DETAILED DESCRIPTION

[0045] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 5 The present application is further described in detail.

[0048] The first reinforcing plate 31 is fixed with a first plug 311 close to one side of the first side plate 1, the first slot 11 is formed on the outer side wall of the first side plate 1, the first plug 311 is a T-shaped block, and the first plug 311 is in plug-in cooperation with the first slot 11. The second reinforcing plate 32 is fixed with a second plug 321 close to one side of the second side plate 2, the second slot 21 is formed on the outer side wall of the second side plate 2, the second plug 321 is a rectangular block, and the second plug 321 is in plug-in cooperation with the second slot 21.

[0049] Referring to Figure 2 and Figure 4 , the outer side wall of the first side plate 1 is provided with a first fixing assembly 4, and the first fixing assembly 4 fixes the first reinforcing plate 31. The first fixing assembly 4 comprises a first fixing block 41, a positioning block 42 and a spring 43, the first fixing block 41 is fixed with the first side plate 1, the first fixing block 41 is provided with a mounting groove 411 close to one side of the first reinforcing plate 31, and the first reinforcing plate 31 is provided with a positioning groove 312 close to one side of the first fixing block 41.

[0050] The spring 43 is located in the mounting groove 411, one end of the positioning block 42 is also located in the mounting groove 411, the spring 43 is located below the positioning block 42, one end of the spring 43 is fixed with the bottom of the positioning block 42, the other end of the spring 43 is fixed on the groove bottom of the mounting groove 411. The top surface of the positioning block 42 is an inclined surface, the side of the top surface of the positioning block 42 close to the second side plate 2 is low, and the side away from the second side plate 2 is high.

[0051] When the reinforcing mechanism 3 is installed, the first reinforcing plate 31 is installed with the first side plate 1, the first plug block 311 is inserted into the first plug slot 11, when the end of the first reinforcing plate 31 away from the second side plate 2 contacts with the top surface of the positioning block 42, the first side plate 1 pushes the positioning block 42, the positioning block 42 extrudes the spring 43 downward, and the first side plate 1 extrudes the positioning block 42 into the mounting groove 411.

[0052] When the positioning block 42 is aligned with the positioning groove 312, the positioning block 42 is inserted into the positioning groove 312 under the action of the spring 43, the side wall of the positioning block 42 contacts with the side wall of the positioning groove 312, thereby reducing the possibility of the first plug block 311 sliding out of the first plug slot 11, and increasing the stability of the first side plate 1.

[0053] The lower side of the positioning block 42 is provided with a pressing block 44, the pressing block 44 is a magnetic block, the lower side of the pressing block 44 is rotatably connected with a threaded rod 45, the spring 43 is sleeved on the threaded rod 45, the threaded rod 45 penetrates downwardly through the first fixed block 41 and is threadedly connected with the first fixed block 41, the bottom of the threaded rod 45 is fixed with a push block 46. After the positioning block 42 is inserted into the positioning groove 312, the push block 46 is rotated to make the pressing block 44 abut against the bottom of the positioning block 42, the pressing block 44 is attracted and fixed with the positioning block 42, thereby increasing the stability of the positioning block 42 in the positioning groove 312, and increasing the stability of the connection between the first reinforcing plate 31 and the first side plate 1.

[0054] When the first reinforcing plate 31 is disassembled, the push block 46 is first rotated to make the threaded rod 45 drive the pressing block 44 to move downwardly, since the pressing block 44 is attracted and fixed with the positioning block 42, in the process that the threaded rod 45 moves downwardly, the pressing block 44 drives the positioning block 42 to move downwardly, and the positioning block 42 extrudes the spring 43 downwardly; when the positioning block 42 completely enters into the mounting groove 411, the first plug block 311 is pulled out of the first plug slot 11, thereby the reinforcing mechanism 3 is removed from the angle steel.

[0055] When the positioning block 42 is completely inserted into the mounting groove 411, the suction force between the positioning block 42 and the abutting block 44 is greater than the elastic force of the spring 43, and as the positioning block 42 continues to drop, the elastic force of the spring 43 continues to increase. When the threaded rod 45 continues to move downward, the elastic force of the spring 43 will be greater than the suction force between the positioning block 42 and the abutting block 44, so that the positioning block 42 and the abutting block 44 are separated, and the top of the positioning block 42 is stretched out of the mounting groove 411 under the action of the elastic force of the spring 43, thereby facilitating the next installation of the first reinforcing plate 31.

The mounting frame 6 covers the second fixing block 51 and the second reinforcing plate 32.

[0057] The second fixing block 51 is located at the bottom of the second reinforcing plate 32 and is in contact with the second side plate 2. The second fixing block 51 is fixed with the second side plate 2. The first connecting plate 61 is in contact with the top of the second reinforcing plate 32. The third connecting plate 63 is in contact with the bottom of the second fixing block 51. The second connecting plate 62 is in contact with the side wall of the second reinforcing plate 32 and the second fixing block 51. The first locking bolt 52 penetrates through the third connecting plate 63 and the second fixing block 51 and is threadedly connected with the second reinforcing plate 32.

[0058] In order to increase the stability of the connection between the mounting frame 6 and the second reinforcing plate 32, a second locking bolt 7 is arranged on the first connecting plate 61, and the second locking bolt 7 penetrates through the first connecting plate 61 and is threadedly connected with the second reinforcing plate 32. By arranging the first locking bolt 52 and the second locking bolt 7 to connect the second fixing block 51 and the second reinforcing plate 32, the stability of the connection between the second reinforcing plate 32 and the second side plate 2 is improved.
