[0026] See also Figure 1-4 ,The utility model provides a technical solution:

[0027] A seat panel that is easy to assemble comprises two groups of first seat panels 1, wherein the lower sides of the two groups of the first seat panels 1 are fixedly provided with a clamping block 2, the outer side of the clamping block 2 is penetrated by a clamping groove 22, and a second seat panel 3 is movably provided between the two groups of the first seat panels 1, the second seat panel 3 movably penetrates the first seat panel 1 and extends to the inner side, and the lower side of the second seat panel 3 is located at the inner side of the first seat panel 1 and is fixedly provided with a threaded rod 5, the threaded rod 5 movably penetrates the first seat panel 1 and extends to the lower side, and the outer side of the threaded rod 5 is located at the lower side of the first seat panel 1 and is threadedly sleeved with a butterfly nut 6, the lower side of the first seat panel 1 is penetrated by a through groove 7 for docking the threaded rod 5, and the lower side of the first seat panel 1 is provided with an installation mechanism 4 for docking the clamping block 2, the position of the first seat panel 1 and the second seat panel 3 is adjustable, so that it is convenient for installation and storage, thereby improving flexibility of use.

[0028] Specifically, the mounting mechanism 4 includes a U-shaped block 8 fixedly arranged on the lower side of the first seat plate 1, and a mounting rod 9 is rotatably arranged on the inner side of the U-shaped block 8, and a card frame 10 is fixedly arranged on the outer side of the mounting rod 9, and mounting plates 11 are fixedly arranged on both sides of the card frame 10 on the outer side of the mounting rod 9, and two groups of coil springs 12 are sleeved on the outer side of the mounting rod 9, one end of the two groups of coil springs 12 are connected to the U-shaped block 8, and the other end of the coil spring 12 is connected to the mounting plate 11. The coil spring 12 does not deform in the initial state. When installing the seat plate, it is necessary to rotate the card frame 10 outward first. At this time, the mounting plate 11 can be driven to stretch the coil spring 12, causing the coil spring 12 to deform, and then the elastic potential energy of the coil spring 12 is released, which can drive the card frame 10 to quickly rotate and reset and fit the chair frame, thereby ensuring the installation stability of the seat plate while improving the convenience of use.

[0029] Furthermore, two groups of limiting columns 13 are fixedly provided on both sides of the second seat plate 3, and limiting grooves 14 for docking with the limiting columns 13 are opened on both sides of the first seat plate 1. The limiting columns 13 slide in the limiting grooves 14. Through the limiting cooperation between the limiting columns 13 and the limiting grooves 14, the movement of the first seat plate 1 is facilitated while the connection stability between the first seat plate 1 and the second seat plate 3 is guaranteed.

[0030] It is worth noting that push blocks 15 are fixedly provided on both sides of the card block 2, and the card block 2 is made of soft material. By setting the push blocks 15, the card block 2 can be easily pushed and pressed. At the same time, through the elastic effect of the card block 2, the cross bar of the chair frame can be quickly inserted into the card slot 22.

[0031] It is worth noting that a bayonet 16 is provided on the inner side of the card frame 10 . The bayonet 16 allows the card frame 10 to fit more closely to the chair frame, thereby further improving the connection stability between the card frame 10 and the chair frame.

[0032] In addition, a handle 17 is fixedly provided on the outer side of the card frame 10. The card frame 10 can be easily rotated by providing the handle 17, thereby improving the convenience of operation.

[0033] Working principle: First, adjust the first seat plate 1 and the second seat plate 3 according to the size of the chair frame. After the adjustment is completed, tighten the two sets of butterfly nuts 6 upward to fix the first seat plate 1 and the second seat plate 3. Then, dock the block 2 on the lower side of the first seat plate 1 with the chair frame so that the slot 22 on the block 2 is locked into the cross bar of the chair frame. During the locking process, the card frame 10 is pulled outward by the handle 17. When the card frame 10 moves, it drives the mounting rod 9 to rotate, and the rotation of the mounting rod 9 stretches the coil spring 12, causing the coil spring 12 to deform. When the slot 22 is completely locked on the cross bar of the chair frame, release the handle 17. At this time, the mounting rod 9 is driven to rotate and reset by the rebound force of the coil spring 12. The rotation of the mounting rod 9 drives the card frame 10 to rotate and fit the outside of the cross bar, thereby ensuring the stability of the connection between the block 2 and the cross bar. Then, the other first seat plates 1 and the second seat plates 3 are installed in turn, and the entire seat plate can be assembled to the chair frame.
