Abstract
The utility model discloses an anti-theft nut kit, which comprises a three-groove nut and an external protection housing of a nut. The utility model has advantages of simple structure, easy operation, which can prevent to disassembly by using non-special tools; the utility model is an ideal fastening component for protecting the safety of equipment.
Description
Technical field
The utility model relates to a kind of antitheft clamp structure.
Background technique
At present, outdoor light equipment is as communal facility or air conditioner outdoor machine, the plug-in spare tyres of automobile etc. such as traffic sign, Advertisement label, gardens facilities, usually because of losing that theft causes.But above-mentioned facilities and equipment does not find to take anti-theft measure as yet in installation process.
Summary of the invention
The purpose of this utility model provides a kind of anti-theft nut external member.
For achieving the above object, constitute by following two parts:
A tri-slot nut, this nut are the pipe shape, are evenly distributed with three boss and three grooves at an end of this nut, at the other end of this nut the convex surface of one diameter less than the tri-slot nut diameter are arranged, and at the inwall of this nut screw thread are arranged;
A nut oversheath, this sheath is cylindric, its internal diameter is slightly larger than the convex surface diameter of tri-slot nut, and it highly is slightly larger than the height of tri-slot nut, can only rotate and the state of translation can not take place around tri-slot nut so that can be blocked by tri-slot nut and keep after installing.One reducing is arranged at the bottom of nut oversheath, this reentrant diameter be slightly larger than tri-slot nut convex surface diameter and less than the diameter of tri-slot nut.For tri-slot nut can enter in the nut oversheath, the diameter of tri-slot nut is less than the diameter of the inwall of nut oversheath.
Feature of the present utility model is that also the height of the convex surface of tri-slot nut is greater than the thickness of the bottom of nut oversheath.Like this, the convex surface that the back tri-slot nut is installed can pass the bottom of nut oversheath, helps being fastenedly connected.
The utility model can only be dismantled with special tool.Special tool can be " fourth " font sleeve pipe, and head has three grooves and three boss, and three boss and three grooves with tri-slot nut are corresponding respectively.After the utility model is installed, because the protection of the nut oversheath that can rotate freely is arranged, so can't dismantle with general purpose tool.Because tri-slot nut gos deep into the inboard of nut oversheath, general purpose tool also can't go deep into wherein dismantling, so this product has only with corresponding special tool installing/dismounting, can play antitheft effect.
The utlity model has advantage simple in structure, easy to use, can prevent the dismounting of non-special tool, thereby be the desirable clamp structure of protection device security.

Embodiment
To shown in Figure 7, the utility model is made of two parts as Fig. 1:
A tri-slot nut 1, this nut 1 is the pipe shape, is evenly distributed with three boss 3 and three grooves at an end of this nut 1, at the other end of this nut 1 convex surface 4 of a diameter less than the nut diameter is arranged, and at the inwall of this nut screw thread 5 is arranged;
A nut oversheath 2, this sheath 2 is cylindric, its internal diameter is slightly larger than the convex surface diameter of tri-slot nut 1, and it highly is slightly larger than the height of tri-slot nut 1, so that can be blocked and keep can not to take place around tri-slot nut 1 rotation the state of translation after installing by tri-slot nut 1; The reducing of the inboard of nut oversheath 2 is reducing 6, and the slightly larger in diameter of this reducing 6 is in the diameter of the convex surface 4 of tri-slot nut 1 and less than the diameter of tri-slot nut 1.The height of the convex surface of tri-slot nut 1 is greater than the thickness of the inboard of nut oversheath.Like this, the back tri-slot nut is installed is deep into the nut oversheath, help being fastenedly connected.
The utility model can only be dismantled with special tool.Special tool can be " fourth " font sleeve pipe, and head has three grooves and three boss, and three boss and three grooves with tri-slot nut are corresponding respectively.After the utility model is installed, because the protection of the nut oversheath that can rotate freely is arranged, so can't dismantle with general purpose tool.Because tri-slot nut 1 integral body is goed deep into the inboard of nut oversheath 2, general purpose tool also can't go deep into wherein dismantling, so this product has only with corresponding special tool installing/dismounting, can play antitheft effect.
Claims (2)
1. an anti-theft nut external member is characterized in that, is made of following two parts:
