When the pressing plate 30 is pressed and rotates compared with the U-shaped longitudinal frame 20, the transmission assembly 40 drives the supporting assembly 50 to move along the outer wall of the U-shaped longitudinal frame 20, and then supports the side wall of the cross frame 10 to realize the connection between the U-shaped longitudinal frame 20 and the cross frame 10, and the limiting assembly 60 is arranged on the inner wall of the U-shaped longitudinal frame 20, and when the pressing plate 30 is pressed and rotates to a horizontal position compared with the U-shaped longitudinal frame 20, the limiting assembly 60 is used to limit the pressing plate 30.

[0034] When it is necessary to connect the U-shaped vertical frame 20 with the cross frame 10, the U-shaped vertical frame 20 can be placed on the inner side of the U-shaped member formed by the plurality of cross frames 10. At this time, the top support assembly 50 extends between two adjacent groups of cross frames 10, and then the pressure plate 30 is pressed. The pressure plate 30 rotates compared with the U-shaped vertical frame 20. At this time, the transmission assembly 40 drives the top support assembly 50 to move along the outer wall of the U-shaped vertical frame 20, and then supports it to the side wall of the cross frame 10, and utilizes the supporting effect between the top support assembly 50 and the cross frame 10 to fix the U-shaped vertical frame 20 on the inner sides of the plurality of cross frames 10; when the top support assembly 50 supports the side wall of the cross frame 10, the pressure plate 30 rotates to a horizontal position compared with the U-shaped vertical frame 20. At this time, the limiting assembly 60 is used to limit the pressure plate 30, so that the top support assembly 50 can stably support it to the side wall of the cross frame 10, thereby improving the connection firmness between the U-shaped vertical frame 20 and the cross frame 10.

[0035] See also Figure 3 as well as Figure 4In one embodiment, the transmission assembly 40 includes a first stopper 401, a first elastic member 402, a transmission rod 403 and a wedge block 404. The transmission rod 403 penetrates the U-shaped longitudinal frame 20 and cooperates with the U-shaped longitudinal frame 20. The transmission rod 403 and the U-shaped longitudinal frame 20 are perpendicular to each other. One end of the transmission rod 403 extends to the inner side of the U-shaped longitudinal frame 20 and is attached to the pressure plate 30, and the other end extends to the outer side of the U-shaped longitudinal frame 20. The wedge block 404 is provided with two groups, and the two groups of wedge blocks 404 are respectively fixedly arranged on the transmission rod 403 is located on both sides of the rod body on the outside of the U-shaped longitudinal frame 20, the first stop block 401 is fixedly arranged on the outside of the rod body of the transmission rod 403 located on the inside of the U-shaped longitudinal frame 20, one end of the first elastic member 402 is connected to the U-shaped longitudinal frame 20, and the other end is connected to the first stop block 401, which is used to provide elastic support for the transmission rod 403, and the top support assembly 50 includes two groups of top support rods 501, and the two groups of the top support rods 501 are slidably arranged on the outer wall of the U-shaped longitudinal frame 20, and the two groups of the top support rods 501 are respectively located on the opposite sides of the transmission rod 403.

[0036] When the U-shaped longitudinal frame 20 is placed on the inner side of the U-shaped component formed by a plurality of transverse frames 10, the two groups of top support rods 501 extend into between two adjacent groups of transverse frames 10, and then press the pressure plate 30. The pressure plate 30 rotates compared to the U-shaped longitudinal frame 20, and then presses the transmission rod 403 so that the transmission rod 403 moves toward the outside of the U-shaped longitudinal frame 20. When the transmission rod 403 moves, it drives the two groups of wedge blocks 404 to move synchronously. When the two groups of wedge blocks 404 move, they act on one end of the two groups of top support rods 501 respectively, and then push the two groups of top support rods 501 away from each other. When the two groups of top support rods 501 move away from each other, their other ends are respectively supported on the side walls of the two adjacent groups of transverse frames 10. At this time, the U-shaped longitudinal frame 20 can be stuck on the inner side of the U-shaped component formed by a plurality of transverse frames 10, thereby realizing the connection between the U-shaped longitudinal frame 20 and the transverse frame 10.

[0037] See also Figure 3 In one embodiment, the top support assembly 50 also includes a fixed block 502, a second elastic member 503 and a second stop block 504. The fixed block 502 is fixedly installed on the outer wall of the U-shaped longitudinal frame 20. The second stop block 504 is fixedly arranged on the outside of the top support rod 501. The top support rod 501 passes through the fixed block 502 and movably cooperates with the fixed block 502. One end of the second elastic member 503 is connected to the fixed block 502, and the other end is connected to the second stop block 504, which is used to provide elastic support for the top support rod 501.

[0038] When the pressing plate 30 is compressed and rotated relative to the U-shaped longitudinal frame 20, the transmission rod 403 moves relative to the U-shaped longitudinal frame 20, the first elastic member 402 is compressed, and at the same time the wedge block 404 pushes the top support rod 501 so that the top support rod 501 moves relative to the fixed block 502, and the second elastic member 503 is compressed; when it is necessary to detach the U-shaped longitudinal frame 20 from the inner side of the U-shaped member formed by the plurality of cross frames 10, the pressing plate 30 can be lifted up so that the pressing plate 30 rotates in the opposite direction relative to the U-shaped longitudinal frame 20. At this time, the first elastic member 402 pushes the transmission rod 403 to move toward the inside of the U-shaped longitudinal frame 20, so that the wedge block 404 is removed from the end of the top support rod 501, and the second elastic member 503 pushes the top support rod 501 to move in the opposite direction compared to the fixed block 502, so that the other end of the top support rod 501 is separated from the corresponding side wall of the cross frame 10, thereby releasing the restricted state between the U-shaped longitudinal frame 20 and the cross frame 10. At this time, the U-shaped longitudinal frame 20 can be removed from the inside of the U-shaped component formed by several cross frames 10.

[0039] See also Figure 3 In one embodiment, a groove 201 is formed on the inner wall of the U-shaped longitudinal frame 20 , and the pressing plate 30 is hingedly disposed inside the groove 201 .

[0040] By setting the groove 201, the pressing plate 30 can be rotated into the groove 201 when pressed, thereby preventing the pressing plate 30 from protruding from the inner wall of the U-shaped vertical frame 20 after rotating to a horizontal position, thereby avoiding interference with the routing of cables.

[0041] See also Figure 3 In one embodiment, a sliding cavity 202 is formed on the inner wall of the groove 201, an inclined surface is formed on one end of the pressure plate 30, and the limiting assembly 60 includes a limiting plate 601 and a third elastic member 602. One end of the limiting plate 601 extends into the sliding cavity 202 and is connected to the inner wall of the sliding cavity 202 through the third elastic member 602, and the other end extends into the groove 201. The third elastic member 602 is used to provide elastic support for the limiting plate 601.

[0042] When the pressure plate 30 is pressed and rotates into the groove 201, the inclined surface at one end of the pressure plate 30 acts on the end of the limit plate 601 located in the groove 201, thereby pushing the limit plate 601 to move the limit plate 601 into the sliding cavity 202. When the pressure plate 30 passes over the limit plate 601 and rotates to a position below the limit plate 601, the third elastic member 602 pushes the limit plate 601 to move the limit plate 601 into the groove 201. When the limit plate 601 moves, it fits the upper surface of the pressure plate 30, thereby limiting the pressure plate 30. When leaving, the limit plate 601 can be pushed to make the limit plate 601 move into the sliding cavity 202. When the limit plate 601 moves, it is removed from the upper surface of the pressure plate 30. At this time, the first elastic member 402 pushes the transmission rod 403 to make the transmission rod 403 move toward the inside of the U-shaped longitudinal frame 20, thereby ejecting the pressure plate 30 from the inside of the groove 201. At the same time, the second elastic member 503 pushes the top support rod 501 to move relative to the fixed block 502, so that the top support rod 501 is separated from the corresponding cross frame 10, thereby releasing the clamping state of the U-shaped longitudinal frame 20. At this time, the U-shaped longitudinal frame 20 can be taken out from the inside of the U-shaped component formed by several cross frames 10.

[0043] In one embodiment, the first elastic member 402 , the second elastic member 503 and the third elastic member 602 may be springs or metal springs, which are not limited here.

[0044] See also Figure 1 as well as Figure 2 In one embodiment, a grid-type wiring rack is provided, which includes a plurality of horizontal frames 10, a plurality of U-shaped vertical frames 20 and a plurality of the above-mentioned connecting members, wherein the plurality of horizontal frames 10 form a U-shaped member, and the plurality of U-shaped vertical frames 20 are arranged at intervals on the inner side of the U-shaped member, and each group of the U-shaped vertical frames 20 is connected to the U-shaped member through a group of the connecting members.

[0045] In the embodiment of the present invention, when it is necessary to connect the U-shaped vertical frame 20 and the horizontal frame 10, the U-shaped vertical frame 20 can be placed on the inner side of the U-shaped member formed by the plurality of horizontal frames 10. At this time, the top support assembly 50 extends between two adjacent groups of horizontal frames 10, and then the pressing plate 30 is pressed. The pressing plate 30 rotates relative to the U-shaped vertical frame 20. At this time, the transmission assembly 40 drives the top support assembly 50 to move along the outer wall of the U-shaped vertical frame 20, and then supports it to the side wall of the horizontal frame 10. The top support effect between the top support assembly 50 and the horizontal frame 10 is utilized to connect the U-shaped vertical frame 20. It is fixed on the inner side of several cross frames 10; when the supporting assembly 50 supports the side wall of the cross frame 10, the pressure plate 30 rotates to a horizontal position compared to the U-shaped vertical frame 20. At this time, the limiting assembly 60 is used to limit the pressure plate 30, so that the supporting assembly 50 can stably support the side wall of the cross frame 10, thereby improving the connection firmness between the U-shaped vertical frame 20 and the cross frame 10. Compared with the prior art, it can realize a quick connection between the U-shaped vertical frame 20 and the cross frame 10, and has the advantages of simple and quick connection, high connection efficiency, and firm and reliable connection.
