All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it will be understood that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present.
Furthermore, the terms "long," "short," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship based on that shown in the drawings, for convenience of description of the present invention, and are not intended to indicate or imply that the apparatus or elements referred to must have this particular orientation, operate in a particular orientation configuration, and thus should not be construed as limiting the invention.
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 5, the present embodiment provides a stroller including a seat 3 and a frame 4. The two sides of the seat 3 are fixedly connected with a first connecting part 1 respectively; two sides of the frame 4 are fixedly connected with a second connecting part 2 respectively.
The first connecting part 1 includes a positioning plate 101, a button 102, a hooking plate 103, a latch 104, and a spring (not shown). A hook slot 1011 is provided in the middle of the positioning plate 101. The lower end of the button 102 is connected with the upper end of the hook plate 103. A sliding hook 1031 for hooking the hook slot 1011 is arranged on one side of the hook plate 103 close to the positioning plate 101. One side of the latch 104, which is close to the positioning plate 101, is connected to the positioning plate 101 through a spring, and one side of the latch 104, which is far away from the positioning plate 101, is connected to the hook plate 103, and when the sliding hook 1031 is close to the hook slot 1011, the latch 104 compresses the spring under the driving of the hook plate 103. The second connecting part 2 is provided with a bolt hole 201 at one side close to the first connecting part 1, and when the chair frame and the frame 4 are connected, the spring drives the latch 104 to be inserted into the bolt hole 201.
Further, the side of the first connecting portion 1 near the second connecting portion 2 further includes a first housing 105. A boss 1032 extending to the outside of the first housing 105 is arranged on one side of the hook plate 103 away from the positioning plate 101; the second connection part 2 is pressed against the boss 1032 to insert the hook 1031 into the hook groove 1011.
Preferably, in order to obtain suitable rigidity and elasticity of the hooking plate 103, the hooking plate 103 is made of polyoxymethylene material.
In this embodiment, in order to facilitate the seat 3 being put on the frame 4 from top to bottom without being blocked, an end of the bottom of the latch 104 near the second connecting portion 2 is a bevel structure 1041.
In this embodiment, a lateral chute 1012 is provided at the lower end of the positioning plate 101, the latch 104 is mounted in the lateral chute 1012, and the spring is located between the bottom of the lateral chute 1012 and the latch 104. An end of the latch 104, which is far away from the second connecting portion 2, is provided with a relief groove, and an end of the spring, which is far away from the positioning plate 101, is inserted into the relief groove.
Preferably, a bevel 1033 is provided at a side of the lower end of the hook plate 103 near the latch 104, and when the bevel 1033 moves downward from top to bottom, the latch 104 moves in a direction near the positioning plate 101.
The following is a description of the use of the stroller:
(1) When the seat 3 needs to be detached from the frame 4, the first and second connection portions 1 and 2 are in the state shown in fig. 3, and the latch 104 has been inserted into the latch hole 201:
(1) pressing the button 102, and sliding the button 102 downwards drives the hook plate 103 to slide downwards;
(2) on the other hand, since the second connecting portion 2 is disposed on the right side of the first connecting portion 1, after the hook plate 103 slides down a small distance, the boss 1032 is pushed to the left by the second connecting portion 2, and as the hook plate 103 continues to slide down, the sliding hook 1031 slides into the groove to hook the hook slot 1011 due to the left force;
(3) on the other hand, since the lower end of the hook plate 103 is connected with the latch 104 through the inclined plane 1033, when the hook plate 103 slides down, the latch 104 is pushed to the left by the inclined plane 1033, and finally when the hook slot 1011 is hooked by the sliding hook 1031, the latch 104 is pushed to the leftmost side which can be reached, and leaves the latch hole 201; the state is locked by the slide hook 1031 at this time, and the latch 104 is not reset due to the release of the button 102;
(4) then, the seat 3 and the frame 4 can be separated only by holding the seat frame upwards;
(5) during the upward movement of the chair frame, the boss 1032 and the second connecting portion 2 generate sliding friction, once the chair frame moves to the first connecting portion 1 and the second connecting portion 2 are separated, the second connecting portion 2 cannot bear against the boss 1032 any more, at this time, the sliding hook 1031 loses the left thrust, and the sliding hook 1031 moves to the right to restore to the original position due to the elasticity of the hook plate 103, so as to separate from the hook slot 1011;
(6) once the sliding hook 1031 is separated from the hook groove 1011, the spring drives the latch 104 to move to the right, the latch 104 pushes the hook plate 103 and the button 102 up through the inclined plane 1033, and finally, the reset of the whole first connecting part 1 is realized;
(2) If the seat 3 is to be mounted on the frame 4, the seat 3 is directly put into the frame 4 from top to bottom:
(1) when the seat 3 is put into the frame 4 from top to bottom, since the right side of the lower end of the latch 104 is the bezel structure 1041, the latch 104 compresses the spring along the lateral chute 1012 by the bezel structure 1041, so that the seat 3 can be inserted into the frame 4;
(2) when the latch 104 is aligned with the latch hole 201, the latch 104 is inserted into the latch hole 201 by the action of the spring, and the connection of the first connection portion 1 and the second connection portion 2 is achieved.
In the stroller provided in this embodiment, only one hand is required to press the buttons 102 on both sides (since the first connecting portion 1 has a memory function of maintaining a locked state, the user can release his hands after pressing, and the user does not need to maintain pressing), and then the user can lift the seat 3 with one hand, thereby completing the operation of disassembling the seat 3 and the frame 4.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
