DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 In this embodiment, a height-adjustable pallet includes a pallet body 1, a connecting rod 2 is fixedly connected to the bottom of the pallet body 1, a support frame 3 is sleeved on the outer surface of the connecting rod 2, a limiting structure 4 is set between the connecting rod 2 and the support frame 3, and a protective structure 5 is set on the pallet body 1.

[0025] Specifically, the protective structure 5 is composed of nine parts: a first groove 501, a second groove 502, a first protective plate 503, a second protective plate 504, a connecting rope 505, an insert 506, a slot 507, a first magnet 508 and a second magnet 509. Slide grooves are provided on the left and right inner walls of the first groove 501 and the front and rear inner walls of the second groove 502. Slide blocks are fixedly connected to the left and right sides of the first protective plate 503 and the front sides of the second protective plate 504. The slide grooves are slidably connected to the slide blocks. The outer wall of the insert 506 is provided with a plurality of sliding grooves. The surface fits with the inner wall of the slot 507, and the first magnet 508 and the second magnet 509 are attracted to each other by opposite charges, pulling the first protective plate 503 and the second protective plate 504 upward to expose the slot 507. At this time, with the cooperation of the connecting rope 505, the plug 506 is inserted into the slot 507, so that the first magnet 508 and the second magnet 509 attract each other, fixing the plug 506, and then completing the positioning of the first protective plate 503 and the second protective plate 504, thereby protecting the goods placed on the pallet body 1.

[0026] Specifically, the limiting structure 4 consists of six components: a mounting shell 401, a connecting column 402, a spring 403, a movable arm 404, a limiting block 405 and a limiting slot 406. The limiting block 405 passes through the mounting shell 401 and the support frame 3 at one end close to the connecting rod 2 and extends to the interior of the limiting slot 406. A sliding hole is provided at the top of the mounting shell 401, and the top of the movable arm 404 extends to the outside of the mounting shell 401 through the sliding hole. The outer surface of the limiting block 405 fits with the inner wall of the limiting slot 406. The number of limiting slots 406 on the connecting rod 2 is not less than four. By pulling the movable arm 404, it interacts with the rebound force of the spring 403, thereby driving the limiting block 405 to engage with the corresponding limiting slot 406, thereby completing the adjustment of the overall height of the tray.

[0027] During implementation, the following steps are followed: first, the overall height of the pallet is adjusted through the connecting rod 2, the support frame 3 and the limiting structure 4 as needed, then the goods are placed on the pallet body 1, and the first protective plate 503 and the second protective plate 504 are pulled upward to expose the slots 507 on their outer surfaces, and finally the insert block 506 is inserted into the slot 507 so that the first magnet 508 and the second magnet 509 attract each other, and the insert block 506 is fixed to complete the positioning of the first protective plate 503 and the second protective plate 504, thereby protecting the goods placed on the pallet body 1.

[0028] To sum up, the height-adjustable pallet, by setting up a protective structure 5, pulls the first protective plate 503 and the second protective plate 504 upward to expose the slot 507. At this time, with the cooperation of the connecting rope 505, the plug 506 is inserted into the slot 507, so that the first magnet 508 and the second magnet 509 attract each other, fix the plug 506, and then complete the positioning of the first protective plate 503 and the second protective plate 504, thereby protecting the goods placed on the pallet body 1 and preventing the goods from slipping.

[0029] Moreover, by setting up the connecting rod 2, the support frame 3 and the limiting structure 4, the connecting rod 2 moves up and down, so that the limiting block 405 corresponds to different limiting grooves 406. Under the interaction of the spring 403 and the movable arm 404, the limiting block 405 is engaged with the corresponding limiting groove 406, thereby adjusting the overall height of the pallet, solving the problem that some existing pallets on the market can be appropriately adjusted in height to meet some work needs, but when there are more goods on the pallet, the goods may slip during the movement, which is not conducive to the use of the staff.
