[0004] In the process of implementing this application, it was found that the technology has the following problems: most of the existing installation clamps for steel gratings fix the steel gratings by first clamping and then installing them to prevent the subsequent movement of the steel gratings during use. However, the outer contour of most installation clamps is matched with the inner contour of the steel grating during use, so that a single set of installation clamps can only be used to install a single type of steel grating during use, thereby reducing the practicality of the equipment.

[0005] For this purpose, a connecting clamp for installing a steel grating is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the outer contour of most installation clamps is adapted to the inner contour of the steel grating during use, so that a single set of installation clamps can only be used to install a single type of steel grating during use. The utility model provides a connecting clamp for steel grating installation.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A connecting clamp for installing a steel grating comprises a base, a support rod is installed on the upper surface of the base, the base is installed at the bottom of the inner wall of the sewer, a connecting block is installed on the upper surface of the support rod, a positioning mechanism for limiting the movement of the steel grating is installed on the top of the connecting block, and protective mechanisms are provided on both sides of the left and right sides of the support rod.

[0013] Furthermore, the two groups of protection mechanisms each include a connecting plate, the two groups of connecting plates are respectively installed on the left and right sides of the support rod, and a V-shaped fixing plate is installed on the opposite sides of the two groups of connecting plates.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model drives the fixing rod, bevel gear 1 and bevel gear 2 to rotate by rotating the connecting rod, and then the bevel gear 2 is installed on the outer surface of the two-way threaded rod, so that the subsequent bevel gear 2 drives the two-way threaded rod to trigger the two groups of L-shaped limit plates to slide in the slots of the fixing plate during the rotation, and the left and right inner walls of the two groups of L-shaped limit plates are respectively abutted against the non-adjacent inner walls of a group of grooves in the central area of ​​the steel grating, so that the two groups of L-shaped limit plates limit the moving position of the steel grating inside the sewer pipe, thereby completing the installation of the steel grating; the spacing between the two groups of L-shaped limit plates can be adjusted and moved, so that the positioning mechanism can be clamped inside the steel gratings with different inner diameters of the grooves during use, thereby expanding the positioning range of the device and thus improving the practicality of the device.

[0026] like Figures 1 to 3As shown, the positioning mechanism 5 includes a fixing plate 501, a slot is provided on the upper surface of the fixing plate 501, the fixing plate 501 is mounted on the upper surface of the connecting block 3, through holes are provided on the inner walls on the left and right sides of the slot of the fixing plate 501, two sets of through holes of the fixing plate 501 are rotatably connected with a bidirectional threaded rod 502 inside, and two sets of L-shaped limiting plates 506 are connected to the outer threads of the bidirectional threaded rod 502, and the two sets of L-shaped limiting plates 506 are slidably connected to the inside of the slot of the fixing plate 501, and the upper surface of the fixing plate 501 is mounted A U-shaped fixing plate 503 is provided, a through hole is provided on the upper surface of the U-shaped fixing plate 503, a fixing rod 504 is connected to the through hole of the U-shaped fixing plate 503 for damping rotation, a card slot is provided on the upper surface of the fixing rod 504, a connecting rod 505 is connected to the card slot of the fixing rod 504, a bevel gear 1 507 is installed on the outer surface of the bottom end of the fixing rod 504, the outer teeth of the bevel gear 1 507 are meshed and connected with a bevel gear 2 508, and the bevel gear 2 508 is installed on the outer surface of the bidirectional threaded rod 502;

[0027] Specifically, when the subsequent base 1 is installed to the bottom of the inner wall of the sewer at the lower end of the steel grating and the positions of the two groups of L-shaped limit plates 506 are located at the lower end of a group of grooves in the central area of ​​the steel grating, the fixing rod 504, the bevel gear 1 507 and the bevel gear 2 508 are driven to rotate by rotating the connecting rod 505, and then the bevel gear 2 508 is installed on the outer surface of the two-way threaded rod 502, so that the subsequent bevel gear 2 508 drives the two-way threaded rod 502 to trigger the two groups of L-shaped limit plates 506 in the slots of the fixing plate 501 during the rotation process. The two groups of L-shaped limit plates 506 are slid to respectively abut the inner walls on the left and right sides of a group of non-adjacent inner walls of a groove in the central area of ​​the steel grating, so that the two groups of L-shaped limit plates 506 limit the moving position of the steel grating inside the sewer pipe, thereby completing the installation of the steel grating; the spacing between the two groups of L-shaped limit plates 506 can be adjusted and moved, so that the positioning mechanism 5 can be clamped inside the steel grating with different inner diameters of the grooves during use, thereby expanding the positioning range of the device and thus improving the practicability of the device.

[0028] like Figure 1 and Figure 2 As shown, the inner walls of the two groups of L-shaped limit plates 506 are both installed with support blocks 6; specifically, when the top of the inner walls of the subsequent two groups of L-shaped limit plates 506 abut against the upper surface of the steel grating, the two groups of support blocks 6 are positioned so as to be respectively arranged at the lower end of the top of the inner walls of the two groups of L-shaped limit plates 506, so that the two groups of support blocks 6 abut against the lower surface of the steel grating during use, thereby limiting the downward movement of the steel grating during use by the two groups of support blocks 6, thereby improving the stability of the subsequent positioning mechanism 5 in positioning the steel grating.

[0029] like Figure 1 and Figure 2 As shown, the positions of the left and right outer surfaces of the U-shaped fixing plate 503 and the left and right ends of the bevel gear 507 are kept parallel; specifically, by keeping the positions of the left and right outer surfaces of the U-shaped fixing plate 503 and the left and right ends of the bevel gear 507 parallel, the left and right outer surfaces of the U-shaped fixing plate 503 limit the sliding paths of the two groups of L-shaped limiting plates 506 in the slots of the fixing plate 501, thereby avoiding as much as possible the collision of the two subsequent groups of L-shaped limiting plates 506 with the left and right ends of the bevel gear 507 during the movement.

[0030] like Figure 1 and Figure 2 As shown, the left and right corners of the upper surface of the two groups of L-shaped limit plates 506 are both set to an arc shape; specifically, the exposed corners at the top of the two groups 206 are set to an arc angle, so that subsequent vehicles rolling over the upper surface of the two groups 206 are not easily damaged by the two groups 206, thereby improving the safety of the subsequent 206 during use.
