DETAILED DESCRIPTION

[0023] In order to make the person skilled in the art more clear and clear the technical scheme of the utility model, the utility model is described in further detail below in combination with examples and drawings, but the embodiment of the utility model is not limited to this.

[0024] Example one

[0025] As Figs. 1-3As shown, this embodiment provides a retractable plywood pallet, including a fixed plate 1, a fixed tube 2 fixed to the bottom of the fixed plate 1, a rotating shaft 3 rotatably mounted inside the fixed tube 2, a bevel gear 4 mounted on the top side wall of the rotating shaft 3, and screws 5 evenly mounted on the outside of the fixed tube 2. A bevel gear 6 is fixed to one end of the screw 5, and the bevel gear 6 meshes with the bevel gear 4. A sleeve 7 is threaded onto the other end of the screw 5, a fixed block 8 is fixed to one end of the sleeve 7, a movable plate 9 is fixed to the top of the fixed block 8, and hinge rods 10 are hinged to both sides of the movable plate 9. The other end of the connecting rod 10 is hinged to the fixed plate 1. A slot 13 is provided at the connection between the outer side of the fixed plate 1 and the movable plate 9. A worm gear 11 is installed on the bottom side wall of the rotating shaft 3. A worm 12 is rotatably installed inside the fixed tube 2, and the worm 12 meshes with the worm gear 11. A support block 14 is fixed at the bottom of each fixed block 8. A through-hole 15 is provided at the bottom of the support block 14. An installation groove 16 is provided on the inner top wall of the through-hole 15. A buffer block 17 is slidably installed inside the installation groove 16. A buffer seat 18 is fixed at the bottom of the buffer block 17. A spring 19 is sleeved on the outer side of the buffer seat 18.

[0026] Depending on the size of the items to be stored, the worm gear 12 is rotated, which drives the worm wheel 11 and the rotating shaft 3 to rotate. The rotating shaft 3 drives the first bevel gear 4 to rotate, and the first bevel gear 4 simultaneously drives the second bevel gear 6 and the screw 5 to rotate. Under the limit of the slot 13 and the movable plate 9, the screw 5 pushes the sleeve 7, the fixed block 8, and the movable plate 9 to move outward, so that the movable plate 9 moves away from the fixed plate 1, thus expanding the overall holding area. The fixed plate 1 is placed on the ground or other platform, and the bottom buffer seat 18 contacts the ground or platform, so that the fixed plate 1 and the movable plate 9 are pushed down by the weight of the object and squeeze the spring 19. The elastic force of the spring 19 can play a buffering role.

[0027] Example 2

[0028] In this embodiment, as Figs. 1-3 As shown, a wear-resistant layer 20 is provided on the top of both the fixed plate 1 and the movable plate 9, and a protective layer 21 is provided on the top of the wear-resistant layer 20.

[0029] The wear-resistant layer 20 protects the top of the fixed plate 1, preventing burrs on the top of the fixed plate 1 and the movable plate 9 from damaging the bottom of the item, while the protective layer 21 acts as a buffer.

[0030] In this embodiment, a handle is fixed to one end of the worm gear 12, and the handle is a non-slip handle.

[0031] The anti-slip handle makes it easy for workers to rotate, causing the worm gear 12 to rotate and drive the worm wheel 11 to rotate.

[0032] In the embodiment, the bottom of the buffer seat 18 is provided with a non-slip pad, and the non-slip pad is a rubber non-slip pad.

[0033] The non-slip effect of the bottom of the buffer seat 18 is increased by the rubber non-slip pad, and the stability of the whole is improved.

[0034] In the embodiment, the two ends of the rotating shaft 3 are provided with bearings, and the outer sides of the bearings are fixedly connected with the bottom of the fixed plate 1 and the inner bottom wall of the fixed tube 2, respectively.

[0035] The protection effect of the fixed plate 1 and the fixed tube 2 is increased by the bearings, and the friction between the rotating shaft 3 and the fixed plate 1 and the fixed tube 2 is reduced.

[0036] The above is only further embodiments of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the conception of the present application within the scope disclosed by the present application, and all of them belong to the protection scope of the present application.
