Abstract
The utility model relates to a nut, in particular to a theft-proof nut, which comprises a theft-proof nut main body and a protective outer ring, wherein the appearance of the theft-proof nut main body is a cylinder shape, the protective outer ring is in a tubular shape whose inner diameter is bigger than the outer diameter of the theft-proof nut main body, the theft-proof nut main body and the protection outer ring are provided with chutes which are mutually anastomotic, the protective outer ring is sleeved on the periphery of the theft-proof nut main body, is clamped and is moveably connected, and the upper end surface of the theft-proof nut main body is further provided with a wedge-shaped mounting groove which is from shallow to deep along the mounting direction of the nut. The theft-proof nut further has a theft-proof function, and can be widely used in electric systems, communication systems and highways.
Description
Technical field
The utility model relates to a kind of nut, relate to a kind of in field facilities such as electric power system, communication system and expressway the anti-theft nut of fastenings or member, particularly a kind of anti-theft nut of protecting outer ring and nut body to maintain an equal level.
Background technique
Present anti-theft nut has nut body and protection outer ring, the external form of nut body is a cylinder type, protecting jacket is that an internal diameter is greater than this body diameter of anti-theft nut tubular, anti-theft nut body and protection outer ring have the draw-in groove that coincide mutually, and the periphery that the protection outer ring is enclosed within the anti-theft nut body sticks and rotatable connection; The nut body upper end has the groove of tightening, and a kind of is that the anti-theft nut body has than the high height in protection outer ring, tightens groove in order that the nut body upper end has larger area, tighten easily, yet this gives the antitheft certain difficulty of having brought; Another kind is that the protection outer ring has the height higher than nut body, in order that better reach antitheft effect, this brings certain difficulty for again last jack panel.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provide a kind of tighten easier, the better anti-theft nut of anti-theft effect.
The purpose of this utility model is achieved in that the anti-theft nut, comprise nut body and protection outer ring, the external form of nut body is a cylinder type, the protection outer ring is the tubular of an internal diameter greater than the nut body external diameter, anti-theft nut body and protection outer ring have the draw-in groove that coincide mutually, and the periphery that the protection outer ring is enclosed within nut body sticks and rotatable connection; The upper-end surface of nut body also has along the wedge shape mounting groove of nut installation direction by shallow intensification; It is characterized in that: the protection outer ring has with nut body and has the same high height; In order better to realize the utility model, the last outer of described nut body has the triangle or the trapezium structure of protrusion, and described protection outer ring has the structure that matches with nut body.
The beneficial effects of the utility model are: so antitheft protection outer ring that lowers the curtain has higher height, helps the protection of nut body, can further reach antitheft purpose.
