[0028] Please refer to Figures 1-4 As shown, a combined steel grating includes a first plate body 1 and a second plate body 2;

[0029] Slots 3 and insert plates 4 are provided at corresponding positions on the sides of the first plate body 1 and the second plate body 2. The insert plate 4 is U-shaped, and the slot 3 is adapted to the insert plate 4. The insert plate 4 is movably inserted into the slot 3, and the insert plate 4 and the slot 3 are fixedly connected by a connection component 5;

[0030] Each set of the connection components 5 includes two connection plates 53. Limiting rods 55 are respectively installed at both ends of the side of the connection plate 53. Limiting holes 56 are symmetrically opened on the side walls at both ends of the insert plate 4 and the slot 3, and the limiting holes 56 are inserted into each other; during work, the insert plate 4 on the first body is inserted into the slot 3 on the second body to assemble the first body and the second body together, and at the same time, the limiting holes 56 opened on the side walls of the insert plate 4 and the slot 3 are aligned. Then, the two limiting rods 55 are respectively inserted into the corresponding limiting holes 56 on the insert plate 4 and the slot 3 through the connection plate 53, so that the insert plate 4 and the slot 3 can be connected together, and further the assembly of the first plate body 1 and the second plate body 2 is more stable.

[0031] A threaded rod 52 is installed in the middle of the connecting plate 53. The threaded rod 52 and the limiting rod 55 are arranged on the same side. Rotating sleeves 51 are arranged in the middle of the two connecting plates 53. The two threaded rods 52 are respectively threadedly connected to the two ends of the rotating sleeve 51. Vertical grooves 57 with open tops are respectively formed on the side walls at both ends of the insertion plate 4 and the slot 3. The vertical grooves 57 are arranged at the middle positions between the two limiting holes 56. The size of the threaded rod 52 is adapted to that of the vertical groove 57. During operation, the threaded rod 52 is placed from top to bottom at the bottom of the vertical groove 57, and the connecting plate 53 and the limiting rod 55 are placed outside the slot 3. Then the rotating sleeve 51 is rotated, thereby driving the two threaded rods 52 to move towards the inside of the rotating sleeve 51, and then driving the connecting plate 53 and the limiting rod 55 to move towards the middle of the slot 3, so that the limiting rod 55 is inserted into the corresponding limiting hole 56. Through the cooperation of the rotating sleeve 51 and the threaded rod 52, the connecting plate 53 can be limited, so that the limiting rod 55 is stably inserted into the limiting hole 56.

The rotation of the connecting plate 53 is restricted by the limiting plate 54, so that the rotating sleeve 51 can drive the threaded rod 52 and the connecting plate 53 to move left and right, realizing the installation and disassembly of the connecting component 5.

[0034] The length of the horizontal bar part at the top of the limiting plate 54 is greater than the length of the limiting rod 55; during operation, when the threaded rod 52 is placed in the vertical groove 57, by making the length of the horizontal bar part at the top of the limiting plate 54 greater than the length of the limiting rod 55, when the limiting rod 55 is not inserted into the limiting hole 56, the end part of the horizontal bar part of the limiting plate 54 is within the range of the vertical groove 57, so that the connecting plate 53 can be limited, facilitating the subsequent accurate insertion of the limiting rod 55 into the limiting hole 56.

[0035] The end of the threaded rod 52 is threadedly connected to the connecting plate 53 through a threaded structure; during operation, so as to facilitate the disassembly and assembly of the threaded rod 52 and the connecting plate 53 and facilitate the replacement of damaged parts.

[0036] The end of the limiting rod 55 is threadedly connected to the connecting plate 53 through a threaded structure; during operation, so as to facilitate the disassembly and assembly of the limiting rod 55 and the connecting plate 53 and facilitate the replacement of damaged parts.
