A support block is fixedly connected to the bottom of the placement board. A folding mechanism is arranged at the bottom of the support block. A fixing mechanism is arranged on the outer wall of the placement board.

[0008] The folding mechanism includes a base plate 1, a locking block fixedly connected to the outer wall of the base plate 1, a base plate 2 fixedly connected to the bottom of the support block, a central rod fixedly connected to the inner wall of the base plate 2, a locking frame rotatably connected to the outer surface of the central rod, a spring 2 fixedly connected to the inner wall of the base plate 2, a push plate 2 fixedly connected to the outer wall of the spring 2, a spring 1 fixedly connected to the inner wall of the base plate 2, a push plate 1 fixedly connected to the outer wall of the spring 1, a slider slidably connected to the inner wall of the base plate 2, and a torsion block fixedly connected to the outer wall of the slider.

[0009] Furthermore, the top of the base plate is fixedly connected to the bottom of the support block, the outer wall of the slider is in contact with the outer wall of the lock frame, the outer wall of the push plate is in contact with the outer wall of the lock frame, the outer wall of the lock frame is in contact with the outer wall of the lock block, the outer wall of the push plate is in contact with the outer wall of the lock block, and there are two center rods.

[0010] Furthermore, the fixing mechanism includes a fixing block, the bottom of which is fixedly connected to the top of the base plate.

[0011] Furthermore, the top of the fixing block is fixedly connected to the bottom of the placement plate, and there are two fixing blocks.

[0012] Furthermore, a bidirectional threaded rod is rotatably connected to the inner wall of the fixed block, and a threaded block is threadedly connected to the outer surface of the bidirectional threaded rod. A central block is fixedly connected to the top of the second base plate.

[0029] Please see Figure 1-5 As shown, this utility model is a foldable plastic tray, including a placement plate 11, a connecting block 12 rotatably connected to the inner wall of the placement plate 11, and a support block 13 fixedly connected to the bottom of the placement plate 11. By rotating the two contacting placement plates 11 through the connecting block 12, they become parallel, thereby unfolding the tray. A folding mechanism 1 is provided at the bottom of the support block 13, and a fixing mechanism 2 is provided on the outer wall of the placement plate 11. The folding mechanism 1 includes a bottom plate 101, and a locking block 106 is fixedly connected to the outer wall of the bottom plate 101. A base plate 111 is fixedly connected to the base plate 111. A central rod 102 is fixedly connected to the inner wall of the base plate 111. A locking frame 103 is rotatably connected to the outer surface of the central rod 102. The locking frame 103 located on the outer surface of the central rod 102 can rotate through the central rod 102. A spring 108 is fixedly connected to the inner wall of the base plate 111. A push plate 107 is fixedly connected to the outer wall of the spring 108. The locking block 106 will push the push plate 107 located in contact with its outer wall to move, thereby pushing the spring 108 fixed on the outer wall of the push plate 107 to compress.

[0030] A spring 104 is fixedly connected to the inner wall of the base plate 111, and a push plate 105 is fixedly connected to the outer wall of the spring 104. The push plate 105, which is in contact with the outer wall of the lock frame 103, moves, thereby pushing the spring 104, which is fixed to the outer wall of the push plate 105, to compress. A slider 109 is slidably connected to the inner wall of the base plate 111, and a torsion block 110 is fixedly connected to the outer wall of the slider 109. By moving the torsion block 110, the slider 109, which is fixed to its outer wall, moves. The top of the base plate 101 is fixedly connected to the bottom of the support block 13. The outer wall of slider 109 contacts the outer wall of lock frame 103. When slider 109 moves, it pushes lock frame 103, which is in contact with it, to rotate on the outer surface of center rod 102. The outer wall of push plate 105 contacts the outer wall of lock frame 103. The outer wall of lock frame 103 contacts the outer wall of lock block 106. The outer wall of push plate 107 contacts the outer wall of lock block 106. There are two center rods 102. By releasing torsion block 110, spring 104 pushes push plate 105 to move, thereby causing lock frame 103 to rotate at the same time, so that it is firmly locked with lock block 106.

[0031] The fixing mechanism 2 includes a fixing block 201. The bottom of the fixing block 201 is fixedly connected to the top of the base plate 111, and the top of the fixing block 201 is fixedly connected to the bottom of the placement plate 11. There are two fixing blocks 201. A bidirectional threaded rod 202 is rotatably connected to the inner wall of the fixing block 201. A threaded block 203 is threadedly connected to the outer surface of the bidirectional threaded rod 202. By rotating the bidirectional threaded rod 202, the threaded block 203 located on its outer surface will move along the groove on the surface of the bidirectional threaded rod 202. A center block 204 is fixedly connected to the top of the base plate 111. The outer wall of the bidirectional threaded rod 202 penetrates the inner wall of the center block 204 and extends to the outside. A fixing rod 205 is rotatably connected to the inner wall of the threaded block 203. By rotating the fixing rod 205 located on the inner wall of the threaded block 203, it is disengaged from the base plate 111 and becomes straight. In the upright position, a drive shaft 206 is fixedly connected to the outer wall of the bidirectional threaded rod 202. When the drive shaft 206 rotates, the bidirectional threaded rod 202 fixed to the outer wall of the drive shaft 206 will rotate inside the fixed block 201. A worm gear 207 is fixedly connected to the outer wall of the drive shaft 206. A rotating frame 209 is fixedly connected to the outer wall of the base plate 211. A worm 208 is rotatably connected to the inner wall of the rotating frame 209. The outer surface of the worm 208 meshes with the outer surface of the worm gear 207. When the worm 208 rotates, it will drive the worm gear 207 meshing with it on its outer surface to rotate. At this time, the drive shaft 206 fixed to the outer wall of the worm gear 207 will rotate simultaneously. A handle 210 is fixedly connected to the outer wall of the worm 208. By rotating the handle 210, the worm 208 fixed to its outer wall will rotate inside the rotating frame 209.

[0032] One specific application of this embodiment is:

[0033] When a worker needs to use the tray, the two contacting placement plates 11 are rotated via the connecting block 12 to make them parallel. At this time, the locking block 106, which is fixed to the outer wall of the first base plate 101, moves towards the inner wall of the second base plate 111. Then, the toggle block 110 is activated, causing the slider 109, which is fixed to its outer wall, to move. When the slider 109 moves, it pushes the locking frame 103, which is in contact with it, to rotate on the outer surface of the central rod 102. At this time, the push plate 105, which is in contact with the outer wall of the locking frame 103... The movement causes the spring 104, which is fixed to the outer wall of the push plate 105, to compress. At this time, the locking block 106 enters the base plate 111. The locking block 106 pushes the push plate 107, which is in contact with its outer wall, to move, thereby compressing the spring 108, which is fixed to the outer wall of the push plate 107. Then, releasing the torsion block 110 causes the spring 104 to push the push plate 105 to move, causing the locking frame 103 to rotate simultaneously, firmly locking it against the locking block 106. The advantage of this is... The system facilitates folding and storage of the pallet, saving space. It also provides a fixed position for the unfolded pallet. After the goods are placed, rotating the fixing rod 205 located on the inner wall of the threaded block 203 causes it to detach from the base plate 211 and stand upright. At this time, rotating the handle 210 drives the worm gear 208 fixed on its outer wall to rotate inside the rotating frame 209. When the worm gear 208 rotates, it drives the worm wheel 207 meshing with it on its outer surface to rotate. Simultaneously, the drive shaft 206 fixed on the outer wall of the worm wheel 207 rotates. When the drive shaft 206 rotates, the bidirectional threaded rod 202 fixed on its outer wall rotates inside the fixing block 201. The threaded block 203 on the outer surface of the bidirectional threaded rod 202 moves along the groove on its surface, thereby moving the fixing rod 205 located on the inner wall of the threaded block 203. This system secures the placed goods, preventing them from falling off the pallet when it is moved.
