A manhole cover grid with a tamper-resistant alloy pin

Abstract

This utility model discloses a manhole cover grating with anti-damage alloy pins, including a support frame, a limiting platform fixedly connected to the bottom of the support frame, and a push handle and a shaft seat welded to the outer wall of the support frame. A filter screen plate is inserted into the support frame, and the surface of the support frame has an assembly hole, while the surface of the filter screen plate has an assembly groove. Both the filter screen plate and the support frame are made of metal. The filter screen plate is inserted into the support frame, with the insertion end extending to the surface of the limiting platform. An alloy pin body penetrates through the assembly hole of the support frame until the insertion end of the alloy pin body extends into the assembly groove of the filter screen plate. This effectively supports the manhole cover grating composed of the filter screen plate and the support frame, improving structural strength, reducing deformation and damage, and enhancing safety during use.

A filter screen plate 5 is inserted into the inside of the support frame 1, and an assembly hole 10 is opened on the surface of the support frame 1. An assembly groove 9 is opened on the surface of the filter screen plate 5.

[0023] Alloy pin body 4 is inserted into the assembly hole 10 of the support frame 1, and the insertion end of the alloy pin body 4 extends into the assembly groove 9 of the filter screen plate 5.

[0024] The surface of the filter screen plate 5 is symmetrically provided with finger holes 8, and the center of the surface of the filter screen plate 5 is provided with mounting holes 7.

[0025] As can be seen from the above description, the present invention has the following beneficial effects: both the filter screen plate 5 and the support frame 1 are made of metal. The filter screen plate 5 is inserted into the inside of the support frame 1, and the insertion end of the filter screen plate 5 extends to the surface of the limiting platform 16. The alloy pin body 4 penetrates the assembly hole 10 of the support frame 1 until the insertion end of the alloy pin body 4 extends into the assembly groove 9 of the filter screen plate 5. This effectively supports the manhole cover grid composed of the filter screen plate 5 and the support frame 1, improves the structural strength, makes it less prone to deformation and damage, and improves the safety of use.

[0026] Example 2: Please refer to Figures 1 to 4 As shown, based on Embodiment 1, this utility model provides a technical solution for a manhole cover grating with anti-damage alloy pins: an anti-fall component is installed at the bottom of the support frame 1.
