2. Through being equipped with the through-hole on the stabilizer blade, the through-hole interpolation has the inserted block, and is used with the elastic component on the inserted block. When the bushing is inserted into the first slot, the plug connector can be inserted into the second slot, and the plug block can be inserted into the groove under the action of the elastic component, so that the bushing is pressed by the plug block to be clamped in the groove. When the sliding block is pushed to be inserted into the third slot on the insert block, the insert block can be forced to withdraw from the groove, and unlocking of the supporting leg, the supporting piece and the bushing is achieved. When the sliding block is pushed to withdraw from the third slot on the insert block, the insert block is inserted into the groove under the action of the elastic piece, so that the locking of the insert piece, the support leg and the bushing is realized. The locking and unlocking among the plug connector, the support leg and the bushing can be realized by pushing the sliding block, and the locking and unlocking are convenient and quick. The fixing among the plug connector, the support leg and the bushing can be realized without the need of screw driving.
3. Because the elastic piece continuously acts on the insert block, the insert block does not need to be worried about being separated from the groove. Meanwhile, as the bushing is clamped in the groove, the gap between the insert block and the groove is filled, and shaking can not occur.

Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
The specific embodiments of the present invention are as follows:
embodiment as shown in fig. 1-8, the invention provides a detachable seat support, which comprises a support leg 1, a bushing 2 and a support piece 3. Wherein the supporting leg 1 and the supporting piece 3 are metal pieces, and the lining 2 is made of plastic materials.
As shown in fig. 4, the supporting leg 1 has a top end and a bottom end in its height direction, and the top end side wall of the supporting leg 1 is provided with a plug 4 extending horizontally outward. As shown in fig. 5, the bushing 2 has a head end and a tail end along its length direction, the bushing 2 is sequentially divided into an insertion section 5 and an abutting section 6 along the head end to tail end direction, and the diameter of the bushing 2 in the abutting section 6 is larger than the diameter of the insertion section 5. Meanwhile, the lining 2 is further provided with a second slot 8 on the end wall of the tail end of the lining 2, and the second slot 8 extends along the length direction of the lining 2. As shown in fig. 2-4, the support 3 has legs 9 extending horizontally outwards, and the legs 9 are provided with first slots 7 extending in the length direction of the support. Specifically, support piece 3 in this scheme includes cross-connected first support body and second support body, and the head and the tail both ends of first support body and the head and the tail both ends of second support body all constitute above-mentioned stabilizer blade 9. The insertion section 5 of the bushing 2 is horizontally inserted into the first slot 7 of the supporting leg 9, the plug 4 is horizontally inserted into the second slot 8 of the bushing 2, and the opposite outer walls of the supporting leg 1 and the supporting leg 9 are abutted against the two side outer walls of the bushing 2 and the abutting section 6 to clamp the abutting section 6.
The support structure adopts a spliced connection mode, is firmer than a connection mode of a sheet metal part, and cannot deform. And because the plug connector 4 and the first slot 7 on the support leg 9 extend horizontally, the parallelism is easy to control, and the plug connector is more convenient to plug. The supporting legs 9 are also difficult to shake relative to the plug-in connector 4 when the top groove wall of the first slot 7 presses on the plug-in connector 4 due to gravity or the pressure of the upper cushion after plugging. At the same time, the support structure further reduces the gap between the plug connector 4 and the wall of the first slot 7 by being provided with the bushing 2. And because bush 2 is the plastics material, avoid rocking between stabilizer blade 9 and the plug connector 4 after long-time use and make a sound, play the effect of silence. And the diameter of the lining 2 in the abutting section 6 is larger than that of the inserting section 5, when the plug connector 4 is inserted into the second slot 8, the opposite outer walls of the supporting leg 1 and the supporting leg 9 are abutted against the outer walls of the lining 2 and the two sides of the abutting section 6 and clamp the abutting section 6, so that a gap is not reserved between the supporting leg 9 and the supporting leg 1 any more, and the sound after long-time use caused by direct contact of the supporting leg 9 and the supporting leg 1 is avoided.
And to facilitate the insertion of the insertion section 5 of the bushing 2 into the first slot 7 on the foot 9. As shown in fig. 4 and 6, in this embodiment, the insertion section 5 is divided into a diameter-reduced portion 11 and an equal diameter portion 10 along the head-to-tail direction of the connection section, the diameter of the insertion section 5 in the diameter-reduced portion 11 gradually decreases from the head to the tail, and the diameter of the insertion section 5 in the equal diameter portion 10 is the same as the diameter of the tail end of the diameter-reduced portion 11. Since the diameter of the insertion section 5 in the diameter-reduced portion 14 gradually decreases from the head end to the tail end, the insertion of the insertion section 5 into the first slot 7 can be facilitated. The diameter of the constant diameter portion 10 is the same as the diameter of the tail end of the diameter-reduced portion 11, so that the problem of shaking caused by an excessive gap between the insertion section 5 and the first slot 7 can be avoided.
Meanwhile, in order to further eliminate the gap between the bush 2 and the support leg 1. In this scheme supporting leg 1 is the cylinder structure, and the tail end wall of bush 2 is inwards sunken arcwall face, and the relative outer wall of supporting leg 1 and stabilizer blade 9 offsets with bush 2 and the both sides outer wall of supporting section 6 and presss from both sides tightly when supporting section 6, arcwall face and the laminating of supporting leg 1's outer wall. Because the tail end wall of the lining 2 is an inward concave arc surface, even the supporting leg 1 is of a cylindrical structure, the lining can be attached to the outer wall of the supporting leg 1, so that the structure is firmer, and the appearance is more attractive. Of course, if the supporting leg 1 is in a quadrangular prism structure, the tail end wall of the bushing 2 may also be a flat plane.
In addition, as shown in fig. 4, in this embodiment, when the opposite outer walls of the supporting leg 1 and the leg 9 abut against the bushing 2 and the outer walls of the two sides of the abutting section 6 and clamp the abutting section 6, the top end surface of the supporting leg 1 is flush with the top end surface of the abutting section 6 and the top end surface of the supporting member 3. Because the top end surface of the supporting leg 1 is flush with the top end surface of the abutting section 6 and the top end surface of the supporting piece 3, the problem that the subsequent cushion is uneven after being mounted on a bracket formed by the supporting leg 1 and the supporting leg 9 is avoided, and the installation of the cushion is facilitated.
And in order to achieve locking and unlocking of the positions among the plug connector 4, the bush 2 and the support leg 9. As shown in fig. 4-8, in this embodiment, the side wall of the plug 4 is provided with a groove 12, while the leg 9 is provided with a through hole 13, and the through hole 13 is inserted with an insert block 14, and the insert block 14 is acted on by an elastic member. Specifically, the elastic member in this embodiment is a spring 16, and the outer wall upper cover of the leg 9 is provided with a fixed cover 22, and the insert 14 is partially exposed out of the leg 9 and is located in the fixed cover 22 and covered by the fixed cover 22. One end of the spring 16 abuts against the inner wall of the fixed cover 22, and the other end of the spring 16 abuts against the insert block 14.
Meanwhile, a third slot 15 is arranged on the side wall of the insert block 14, and the third slot 15 is partially exposed out of the support leg 9. The foot 9 is further provided with a slide 17, which slide 17 can slide in relation to said foot 9 and be inserted into or withdrawn from a third slot 15 in the insert block 14. The slider 17 is also located within the fixed cover 22 and is covered by the fixed cover 22. The slider 17 has a head end and a tail end along its length, wherein the head end of the slider 17 is adjacent to the plug 14. In order to avoid the slide block 17 from being skewed in the sliding process, the top end surface of the slide block 17 abuts against the inner wall of the fixed cover 22 to form limit. And the head end of the sliding block 17 is provided with a reducing part 18, and the thickness of the sliding block 17 on the reducing part 11 gradually increases from the head end to the tail end of the locking piece.
When the assembly of the plug 4, the bushing 2 and the foot 9 is required. The sliding block 17 is slid firstly to enable the sliding block 17 to be inserted into the third slot 15 of the plug block 14, and as the thickness of the sliding block 17 on the reducing part 18 gradually increases from the head end to the tail end of the locking piece, the plug block 14 is forced to move in the depth direction of the through hole 13 in the process of inserting the sliding block 17 into the third slot 15, so that the plug block 14 completely exits from the groove 12 on the plug block 4 to complete unlocking. The bushing 2 and the plug 4 can be assembled by freely inserting into the first slot 7 on the leg 9.
In order to facilitate the pushing of the slider 17, the fixed cover 22 is provided with a sliding groove 19 and a positioning groove 20, the sliding groove 19 extends along the length direction of the third slot 15, the slider 17 is provided with a push rod 21, and the push rod 21 passes through the sliding groove 19 and is exposed out of the fixed cover 22. The slider 17 can be inserted into or withdrawn from the third slot 15 by simply pushing the push rod 21 to move. And in this embodiment, the width of the slider 17 is smaller than the width of the third slot 15. The fixed cover 22 is further provided with a positioning slot 20, the positioning slot 20 extends along the width direction of the third slot 15, and when the push rod 21 drives the sliding block 17 to move to the communication position between the sliding slot 19 and the positioning slot 20, the sliding block 17 is inserted into the third slot 15 and the insert block 14 is withdrawn from the groove 12. Since the width of the middle slider 17 is smaller than the width of the third slot 15, the slider 17 can move along the width direction of the third slot 15 after being inserted into the third slot 15. When the push rod 21 drives the sliding block 17 to move to the communication position between the sliding groove 19 and the positioning groove 20, the sliding block 17 is inserted into the third slot 15 and the insert block 14 is already retracted out of the groove 12. Only then need push rod 21 to slide along positioning groove 20. When the push rod 21 receives the limit of the wall of the positioning groove 20, the slide block 17 can not move along the length direction of the third slot 15, the slide block 17 can be always inserted into the third slot 15, the insertion hole can not be inserted into the groove 12, and at the moment, the hands of a user do not need to be always pressed against the push rod 21, so that two hands can be vacated to take and assemble the supporting leg 1, the supporting piece 3 and the lining 2.
And at this time, the spring 16 is in a compressed state because the insert 14 moves a distance in the depth direction of the through hole 13.
After assembly is complete, the user need only push the push rod 21 in the opposite direction so that the slider 17 exits the third slot 15. At this time, after the insert 4, the bush 2 and the support leg 9 are inserted by the restoring force of the spring 16, the spring 16 acts on the insert block 14 to force the insert block 14 to press the bush 2 to deform and squeeze the bush 2 into the groove 12 on the side wall of the insert 4, so that the insert block 14 can clamp the bush 2 by matching with the inner wall of the groove 12, thereby realizing the locking of the insert 4, the support leg 9 and the bush 2. The structure can realize the locking and unlocking of the plug connector 4, the support leg 9 and the bushing 2 without screwing a screw. And there is no concern that the insert block 14 will be pulled out of the recess 12 because the restoring force of the spring 16 will continue to act on the insert block 14. Meanwhile, as the bushing 2 is clamped in the groove 12, the gap between the insert block 14 and the groove 12 is filled, and shaking cannot occur.
The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
