[0025] Specifically, the two fastening bolts 3 are provided to improve the tight fixation between the first steel structure 1 and the second steel structure 2, so that the steel structures can be easily and quickly installed.

[0026] The mounting assembly 4 includes two L-shaped clamping plates 401 fixedly installed at the bottom of the first steel structure 1, two movable grooves 402 are provided on the top outer surface of the second steel structure 2, sliding plates 403 are slidably installed inside the two movable grooves 402, cylinders 404 are fixedly installed on the tops of the two sliding plates 403, reset springs 405 are fixedly installed on the inner bottom walls of the two cylinders 404, movable plates 406 are movably installed on the inner walls of the two cylinders 404, connecting rods 407 are fixedly installed on the tops of the two movable plates 406, rectangular plates 408 are fixedly installed on the tops of the two connecting rods 407, and limiting grooves 409 are provided on the top of the second steel structure 2 and at one end of the two movable grooves 402.

[0027] Specifically, when installing between the first steel structure 1 and the second steel structure 2, the two L-shaped clamping plates 401 are respectively inserted into the rectangular plate 408, and the first steel structure 1 is pressed downward, so that the rectangular plate 408, the connecting rod 407 and the movable plate 406 move downward to squeeze the reset spring 405, and then the first steel structure 1 is rotated so that the two rectangular plates 408 are respectively inserted into the limiting grooves 409, thereby realizing the installation between the first steel structure 1 and the second steel structure 2.

[0028] The tops of the two rectangular plates 408 are each provided with a slot that matches the L-shaped card plate 401 , and the two L-shaped card plates 401 are both mounted in the slots.

[0029] Specifically, when the first steel structure 1 is rotated, the rectangular plate 408 can be driven to move through the connection between the L-shaped clamping plate 401 and the clamping slot.

[0030] The bottoms of the two movable plates 406 are fixedly connected to the tops of the return springs 405 , and a sealing gasket is installed between the contact surfaces of the first steel structure 1 and the second steel structure 2 .

[0031] Specifically, the expansion and compression of the return spring 405 realize the movement of the movable plate 406; and the sealing gasket can intercept rainwater from entering the movable groove 402 and the limiting groove 409, thereby increasing the sealing of the connection between them and reducing the difficulty of disassembly.

[0032] The height of the two movable grooves 402 is greater than the sum of the heights of the cylinder 404 and the connecting rod 407 .

[0033] Specifically, when the first steel structure 1 is pressed downward, the L-shaped clamping plate 401 and the rectangular plate 408 will enter the interior of the limiting groove 409, thereby facilitating the disassembly and assembly work.

[0034] When implementing, follow these steps:

[0035] 1) When disassembling the first steel structure 1 and the second steel structure 2, the two fastening bolts 3 are twisted so that the two fastening bolts 3 are completely separated from the steel structure;

[0036] 2) Then, the first steel structure 1 is rotated so that the rectangular plate 408 is disengaged from the limiting groove 409;

[0037] 3) The rectangular plate 408 is lifted up by the return spring 405, and then the L-shaped card plate 401 is pulled upward, so that the L-shaped card plate 401 is out of the card slot.

[0038] 4) Finally, the disassembly between the first steel structure 1 and the second steel structure 2 is completed.

[0039] To summarize, the steel structure connector, by setting the cooperation between the L-shaped clamping plate 401, the movable groove 402, the sliding plate 403, the cylinder 404 and the reset spring 405, respectively inserts the two L-shaped clamping plates 401 into the rectangular plate 408, presses the first steel structure 1 downward, so that the rectangular plate 408, the connecting rod 407 and the movable plate 406 move downward to squeeze the reset spring 405, and then rotates the first steel structure 1, so that the two rectangular plates 408 are respectively inserted into the limiting groove 409, to achieve the installation between the first steel structure 1 and the second steel structure 2, and further uses two fastening bolts 3 to tightly fix the first steel structure 1 and the second steel structure 2, so that the steel structure can be easily and quickly installed.

[0040] In addition, by installing a sealing gasket between the surfaces of the first steel structure 1 and the second steel structure 2, the sealing gasket can intercept rainwater from entering the movable groove 402 and the limiting groove 409, thereby increasing the sealing of the connection between them and reducing the difficulty of disassembly.
