[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Examples, such as Figures 1 to 8 As shown, this utility model proposes a logistics storage rack hanging plate, including a column 1 and a hanging plate 2 installed on the column 1. The column 1 has multiple connecting holes 101, and the hanging plate 2 is fixedly connected to the column 1 through the connecting holes 101. Two second positioning blocks 202 are fixedly installed on the hanging plate 2. The second positioning blocks 202 are the same size as the connecting holes 101. By inserting the second positioning blocks 202 into the connecting holes 101, the hanging plate 2 can be positioned and prevent the hanging plate 2 from shaking after installation. One end of the second positioning block 202 is chamfered, which facilitates the second positioning block 202 entering the connecting hole 101. A support rod 201 is fixedly installed on the hanging plate 2. The support rod 201 can support the shelf.

[0027] This embodiment also includes a self-locking structure installed on the hanging piece 2. The self-locking structure includes an expansion component, which controls the size of the expansion component and applies pressure to the column 1. When the expansion component is retracted, it can enter the other side of the connection hole 101 through the connection hole 101, and then expand the expansion component so that it abuts against the column 1. At this time, the expansion component cannot pass through the connection hole 101. The self-locking structure can then apply a fastening force to the column through the expansion component, thereby fixing the hanging piece 2 to the column 1.

[0028] Further, the self-locking structure comprises a first bolt 3 threadedly connected to the hanging piece 2, a first hexagonal bolt head 301 fixedly installed on the first bolt 3, and a second bolt 302 threadedly connected in the first bolt 3, and a second hexagonal bolt head 303 fixedly installed on the second bolt 302. By rotating the first hexagonal bolt head 301, the first bolt 3 can be driven to rotate, so that the first bolt 3 moves along the axial direction of the first bolt 3 on the hanging piece 2. Similarly, by rotating the second hexagonal bolt head 303, the second bolt 302 can be driven to move along the axial direction of the second bolt 302.

[0029] The first bolt 3 has a connecting block 304 fixedly installed at one end thereof, the second bolt 302 has a first positioning block 305 rotatably installed thereon, and the expansion assembly is installed on the connecting block 304 and the first positioning block 305. The expansion assembly comprises a plurality of first connecting rods 306 rotatably installed on the connecting block 304, a joint 308 rotatably installed on the first connecting rod 306, and a second connecting rod 307 rotatably installed on the joint 308 and rotatably connected with the first positioning block 305. When the second bolt 302 is rotated to drive the first positioning block 305 to move away from the connecting block 304, the first connecting rod 306 and the second connecting rod 307 will be driven to rotate, and the joint 308 will be driven to move towards the axial direction of the second bolt 302, so that the plurality of first connecting rods 306, the second connecting rod 307 and the joint 308 are retracted, and the expansion assembly can pass through the connecting hole 101. After the expansion assembly passes through the connecting hole 101, the second bolt 302 is reversely rotated to drive the first positioning block 305 to move towards the connecting block 304, so that the plurality of joints 308 are lifted. At this time, the size of the expansion assembly will be larger than that of the connecting hole 101, and the expansion assembly cannot pass through the connecting hole 101 and abuts against the stand 1.

[0030] At this time, the first bolt 3 is rotated to clamp the hanging piece 2 and the expansion assembly against the stand 1, so that the hanging piece 2 is fixedly connected with the stand.

[0031] In this embodiment, the first hexagonal bolt head 301 and the second hexagonal bolt head 303 are provided with anti-loosening assemblies, which prevent the first bolt 3 and the second bolt 302 from loosening. The anti-loosening assembly comprises a limiting rod 4 slidingly installed on the first hexagonal bolt head 301 and the second hexagonal bolt head 303, a plurality of limiting blocks 401 fixedly installed on the limiting rod 4, a connecting seat 402 fixedly installed on the first hexagonal bolt head 301 and the second hexagonal bolt head 303, a clamping plate 403 rotatably installed on the connecting seat 402, a clamping block 405 fixedly installed on the connecting seat 402, and an elastic sheet 404 fixedly installed on the clamping plate 403 and the connecting seat 402. When the first bolt 3 and the second bolt 302 move towards the column 1, the connection between the hanging piece 2 and the column 1 will loosen. By abutting the limiting rod 4 against the hanging piece 2 and the first hexagonal bolt head 301, when the first bolt 3 moves towards the column 1, the limiting rod 4 will move rightwards relative to the first hexagonal bolt head 301. At this time, the rightward moving limiting rod 4 will drive the limiting blocks 401 to move, and at this time, the clamping plate 403 will be located between the two limiting blocks 401. At this time, the movement of the limiting blocks 401 needs to drive the clamping plate 403 to rotate towards the clamping block 405, and under the limiting action of the clamping block 405, the clamping plate 403 cannot rotate towards the clamping block 405, thereby preventing the limiting rod 4 from moving, and further preventing the first bolt 3 from loosening. Similarly, it can be seen that the limiting rod 4 can prevent the second bolt 302 from loosening.

[0032] When the limiting rod 4 is pushed to move towards the column 1, the moving limiting rod 4 can drive the clamping plate 403 to rotate towards the column 1, and after the limiting blocks 401 pass through the clamping plate 403, the clamping plate 403 is reset under the action of the elastic sheet 404, so that the clamping plate 403 enters between the two limiting blocks 401 again.

[0033] Working principle: when the second bolt 302 is rotated to drive the first positioning block 305 to move away from the connecting block 304, it will drive the first connecting rod 306 and the second connecting rod 307 to rotate, and further drive the joint 308 to move towards the axis of the second bolt 302, so that the plurality of first connecting rods 306, second connecting rods 307 and joints 308 are contracted, and the expansion assembly can pass through the connecting hole 101. After the expansion assembly passes through the connecting hole 101, the second bolt 302 is reversely rotated to make the first positioning block 305 move towards the connecting block 304, so that the plurality of joints 308 are lifted. At this time, the size of the expansion assembly will be larger than the connecting hole 101, and the expansion assembly cannot pass through the connecting hole 101 and abuts against the column 1. At this time, rotating the first bolt 3 can make the hanging piece 2 and the expansion assembly clamp the column 1, so as to fixedly connect the hanging piece 2 and the column.

[0034] The above specific embodiments are only several optional embodiments of the present application, and based on the technical scheme of the present application and the related enlightenment of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
