Embodiment 1

[0013] A nut anti-theft and unloading protective cover. The nut anti-theft and unloading protective cover is a hollow cone structure. The upper part of the cone 1 is provided with a circular hole matching the bolt 2 and the upper part of the circular hole is provided with a boss 3 along the circumferential direction , The middle of the boss 3 is provided with a central hole matching the bolt 2. In the tightening process, a round tube is used to punch or press the anti-theft shield with ordinary nuts to make the boss of the anti-theft shield into a flat surface, and then hold the bolts to achieve the anti-theft function.

Embodiment 2

[0015] A nut anti-theft and unloading protective cover. The nut anti-theft and unloading protective cover is a hollow cone structure. The upper part of the cone 1 is provided with a threaded hole matching the bolt 2 and the upper part of the threaded hole is provided with a boss 3 in the circumferential direction , The middle of the boss 3 is provided with a threaded hole that matches the bolt 2, and the outer wall of the nut anti-theft shield is provided with a slot 4, and the left side of the slot 4 is perpendicular to the nut anti-theft shield On the outer wall of the cover, the recess on the right side of the slot 4 is arc-shaped to transition to the outer wall of the nut anti-theft protection cover. During the tightening process, a special clamp is used to rotate clockwise to tighten the cone, and when the clamp is rotated counterclockwise, the cone cannot be disassembled due to the slippage of the clamp, thus realizing the anti-theft and unloading effect of the nut.

Embodiment 3

[0017] A nut anti-theft and unloading protective cover. The nut anti-theft and unloading protective cover is mainly composed of a cylindrical cover body 5 and an anti-theft protective pad 6. The cylindrical cover body 5 is a hollow cylinder structure, and the upper part of the cylinder body is provided with a bolt 2 The outer diameter of the anti-theft pad 6 is smaller than the outer diameter of the cylindrical cover 5, and a threaded hole matching the bolt 2 is provided in the middle of the anti-theft pad 6, and the outer circumference of the anti-theft pad 6 is provided There is a card table 8, the right side of the card table 8 maintains the circular plane structure of the anti-theft pad 6, and the left side of the card table 8 transitions to the circular plane of the anti-theft pad 6 in an arc surface. During the tightening process, a special clamp is used to rotate clockwise to tighten the anti-theft pad. When the anti-theft pad is rotated counterclockwise, the anti-theft p...

Abstract

The invention discloses an anti-theft and anti-disassembly nut shield. The key points of the technical scheme are that the anti-theft and anti-disassembly nut shield is of a hollow cone structure, the upper part of the cone is provided with a round hole matched with a bolt, the upper part of the round hole is provided with a boss along the circumferential direction, and the middle part of the boss is provided with a central hole matched with the bolt. The invention also discloses anti-theft and anti-disassembly nut shields in other three different design schemes. The anti-theft and anti-disassembly nut shield is simple in structure and convenient to use, compared with the original anti-theft nut, the production cost is reduced, and the anti-theft and anti-disassembly nut shield achieves good anti-theft and anti-disassembly effects.

Description

Technical field [0001] The invention relates to a nut anti-theft and unloading accessory, in particular to a nut anti-theft and unloading shield. Background technique [0002] At present, television stations and various newspapers continue to report that highway guardrails, power supply towers and railway facilities in the wild have been stolen and unloaded by criminals, causing huge losses to the country and people's lives and property. In order to solve this problem, the inventor has successively applied for five national patents, which have been partially used on Lianhuo Expressway and Beijing-Zhuhai Expressway, and initially achieved satisfactory results. However, they are all aimed at improving the shape of the nut. Although they have a certain anti-theft effect, the manufacturing cost is relatively high, and they have not reached a wider range of popularization and application. Summary of the invention [0003] The technical problem solved by the present invention is to pro...
