Problems solved by technology

Since the bolts and nuts are often exposed to the outside, they are easy to rust after being washed by rainwater. Even if the anti-corrosion oil is used for maintenance, it can only play a temporary role. In order to improve the safety and stability of the equipment, people have to take The method of frequently replacing bolts is a waste of manpower, material resources, and financial resources
And because the disassembly of bolts is also very convenient, it is often stolen by lawless elements.

Embodiment 1

[0011] The bolt guard reference of this embodiment figure 1 , 2 , which consists of three independent parts, including a cover 1, a cover body 2 and a trapezoidal pad 3, the cover 1 is a metal disc with a mark at the center point, the cover 2 is a bottom with a step, and an upper part with a The metal cylinder of the mouth 4, the trapezoidal pad 3 is a gasket with a trapezoidal shape, the trapezoidal pad 3 is located at the lower opening of the cover body 2, and the cover 1 is located at the upper stop 4 of the cover body 2. In order to make the cover 1 It is not easy to be disassembled. There is an interference fit between the cover 1 and the cover body 2, that is, the diameter of the cover 1 is larger than the diameter of the stop 4; when the cover 2 is rotated by external force, in order to prevent the trapezoidal pad 3 from rotating accordingly, thereby The bolts are loosened, and the height h1 of the bottom of the trapezoidal pad 3 is greater than the height h2 of the bo...

Abstract

The invention relates to a bolt shield, belonging to the technical field of shield structures. The bolt shield is characterized by comprising a shield cap, a shield body and a trapezoid mat which are mutually independent, wherein the shield cap is a metal disc the central point of which has a mark, the shield body is a metal cylinder of which the bottom part is provided with steps and the top part is provided with a spigot, the trapezoid mat is a trapezoid shape and is arranged at the lower part opening part of the shield body, the shield cap is arranged at the upper part spigot part of the shield body, and the shield cap is in interference fit with the shield body, namely the diameter of the shield cap is larger than that of the spigot. The bolt shield in the invention has the advantages of simple manufacture, wide application, considerable prospect, burglary prevention, breakage resistance, gas cutting prevention and corrosion resistance.

Description

1. Technical field [0001] The invention relates to a bolt protective cover, which belongs to the technical field of protective cover structures. 2. Background technology [0002] At present, many outdoor, roadside or field devices need to be fastened with bolts, but the protection of bolts has always been a problem that plagues people. Since the bolts and nuts are often exposed to the outside, they are easy to rust after being washed by rainwater. Even if the anti-corrosion oil is used for maintenance, it can only play a temporary role. In order to improve the safety and stability of the equipment, people have to take The method of frequently replacing bolts is a waste of manpower, material resources and financial resources. And because the disassembly of bolt is also very convenient, it is often stolen by lawless elements. 3. Contents of the invention [0003] The object of the present invention is to solve the shortcomings of the above-mentioned prior art, and provide ...
