[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-3 A spliced ​​steel plate pin comprises a steel plate pin main body 1, a concave splicing end 2 at one end of the steel plate pin main body 1, the concave splicing end 2 is connected to one end of the steel plate pin main body 1 through a connecting plate, and a convex splicing end 3 is provided at the other end, the concave splicing end 2 is provided with a through slot 4, and four locking blocks 4 are arranged in the through slot 4, and four locking slots 6 are provided around the convex splicing end 3, and the four locking slots 6 correspond to and match the four locking blocks 5 one by one, and a rotating shaft 7 passes horizontally through the through slot 4, and an unlocking block 8 is provided at one end of the rotating shaft 7, and the unlocking block 8 is in the through slot 4.

[0020] Among them, four inner grooves are opened on the inner wall of the through groove 4, and four locking blocks 5 are correspondingly arranged below the four inner grooves.

[0021] At the same time, a connecting block is provided at one end of the locking block 5, and the other end of the connecting block is connected to one side of the steel plate pin body 1. A compression spring 9 is provided at the top center part of the locking block 5, and the other end of the compression spring 9 is connected to the top of the inner groove.

[0022] At the same time, there is an unlocking block 8 on one side of the locking block 5. The unlocking block 8 is located inside the connecting block. A plurality of friction strips are provided at the four corners of the outer wall of the unlocking block 8 to increase the friction force, and the unlocking block 8 is adapted to the locking block 5.

[0023] At the same time, the rotating shaft 7 passes through the through slot 4 horizontally and is provided with an unlocking block 8, and the other side of the rotating shaft 7 is adapted to the concave hole opened on one side of the steel plate pin body 1.

[0024] In addition, an unlocking paddle 10 is provided on the rotating shaft 7, and the unlocking paddle 10 passes through a through slot provided on the connecting steel plate.

[0025] In this embodiment, by pushing the steel plate pin body 1, the concave splicing end 2 is connected to the convex splicing end 3, and a locking groove 6 is provided around the outer wall of the convex splicing end 3. A locking block 4 is installed in the concave splicing end 2 and one end of the locking block 4 is set to an arc surface. Under the action of the thrust, the convex splicing end 3 will contact the side of the locking block 4 with the arc surface, and the locking block 4 will be compressed under the action of the compression spring 9 and the thrust. When it is pushed to an appropriate distance, the locking block 4 will be under the action of the compression spring 9 and the locking groove 6, and the locking block 4 will bounce into the locking The locking piece 4 is stuck in the groove 6 to achieve the splicing effect. When it needs to be unlocked, it is only necessary to push the unlocking paddle 10 in the sliding groove opened in the splicing plate to unlock it. The rotating shaft 7 will rotate, and the rotation of the rotating shaft 7 will drive the unlocking block 8 to rotate. The rotation of the unlocking block 8 will make the four corners of the unlocking block 8 contact with the connecting plate, which will open the connecting plate. Because the connecting plate is connected to the locking block 4, the locking block 4 will be under the action of the unlocking block 8, and the compression spring 9 will be compressed again until the convex splicing end 3 leaves the concave splicing end 2 to achieve separation.
