First of all, please refer to Figures 2 to 3, which are the three-dimensional views of the unfolded state and the closed state of this creation. This creation is mainly composed of a table board 1, an L-shaped connecting plate 11, a support rod 2, a tripod 21, and a card system. Sheet 22, interlocking device 3, and retarding device 4 are made up of, hereby the relevant position and structure of each component are described as follows: a table board 1, its back side and L-shaped connecting plate 11 side are screwed in parallel, and this L-shaped The other side of the connecting plate 11 is perpendicular to the table plate 1 and is pivotally provided with an interlocking device 3 on the outer side, and a convex column 111 is protruded on the inner side; There is a clamping piece 22 fixed; the clamping piece 22 has an arc-shaped track 221, and a first limiting groove 222 sunken downward is provided at the top of the track 221, and a first limiting groove 222 with an inclined angle is provided at the bottom. Two limit grooves 223; linkage 3, which has a bent connecting rod 31 and a spring 32; the two ends of the connecting rod 31 form a fixed angle, and connect the pivot with the L-shaped connecting plate 11 at the bending place Connect, the front end of the connecting rod 31 is fixed with the control rod 4, the outside of the rear end is provided with a locking rib 311 protruding into the arc track 221, and a protruding post 312 is provided on the inside to fix one end of the spring 32, and the other end of the spring 32 One end is fixed with the boss 111 on the L-shaped connecting plate 11 .

Please refer to Fig. 4, which is the three-dimensional view and partial enlarged view of the action of the L-shaped connecting plate 11, the clamping piece 22 and the linkage device 3 in this creation. With the above structure, the control rod 4 is pulled up to drive the connecting rod 31. With the L-shaped connecting plate 11, the locking rib 311 on the connecting rod 31 can slide in the track 221 of the locking piece 22, and is limited by the first limiting groove 222 and the second limiting groove 223; When the clamping rib 311 slides to the top of the track 221, the concave groove portion of the first limiting groove 222 can clamp the clamping rib 311 therein. At this time, the spring 33 inside the connecting rod 31 exerts a tightening characteristic and helps Due to the fixation of the locking rib 311 in the first limiting groove 222; if the control rod 32 is pulled up slightly, the locking rib 311 on the connecting rod 31 will be driven to leave the first limiting groove 222 and move along the track 221. Slide to the second limiting groove 223; the second limiting groove 223 has an inclined angle so that the locking rib 311 can be fixed against the upper edge. At this time, the spring 32 rotates with the connecting rod 31 and helps the locking rib 311 is fixed in the second limiting groove 223; on the contrary, if you want to make the locking rib 311 slide from the second limiting groove 223 to the first limiting groove 222, then pull the control rod 32 in an arc upward, that is, drive The clamping rib 311 reversely displaces and resets into the first limiting groove 222 .

Please continue to refer to Figure 5, which is a side view of the action of this creation. The table board 1 is screwed on one side of the L-shaped connecting plate 11, so the pulling control rod 32 makes the locking rib 311 on the track of the locking piece 22. 221 to slide and be fixed in the first limiting groove 222 or the second limiting groove 223, and also drive the table board 1 to limit and rotate so that the table board 1 is in a parallel (expanded) or vertical (folded) state; when in use , the clamping rib 311 is located in the second limiting groove 223 and resists the upper edge of the second limiting groove 223 so that the table top 1 is in a parallel state. Through the design of the inclination angle of the second limiting groove 223, it can avoid collision due to external force, Shaking or excessive pressure on the top of the table 1 causes the locking rib 311 to slide, causing the table 1 to turn over arbitrarily, which completely solves the shortcomings of the conventional structure; The tabletop 1 is in a vertical state in the slot 312, and through the design of the first limiting slot 312, which is recessed downward, it can also prevent the tabletop 1 from being turned over arbitrarily due to external force collisions; And on the side of the L-shaped connecting plate 11, a clamping device is added to fix the slowing device 5, and the pulling control rod 4 can make the slowing device 5 rotate with the table 1 with the side of the support rod 2 as a pivot, and penetrate the oil. The mode of pressure control produces a retarding effect, avoiding the gravity generated by the rotation of the table 1 from causing the whole structure to shake.

At last, please refer to shown in Fig. 6, which is a reference figure of a preferred embodiment of this creation, an L-shaped partition 6 can be set, and its two ends are extended to the lower edge of the table 1 and the control rod 4 respectively, so, Just form a storage space, and then enhance the practical value of this creation.

To sum up, through the limiting effect produced by the linkage device 3 and the limiting groove, the invention can control the opening of the table 1 by pulling the control rod 4 and has good fixation. Compared with the conventional example, it is more labor-saving and It is convenient, and the structural stability is good, so that the safety is greatly improved. It is truly a progressive creation. I have filed a patent application in accordance with the law. I hope that the patent will be granted as soon as possible. It is really convenient.
