Abstract
The utility model relates to a nut, in particular to an anti-theft nut, comprising an anti-theft nut body and a protection outer ring, the shape of the anti-theft nut body is cylindrical, the protection outer ring is a barrel shape, the inner diameter of the protection outer ring is more than the outer diameter of the anti-theft nut body, and the anti-theft nut body and the protection outer ring are provided with clamping grooves which are matched, and the protection outer ring is sheathed and clamped at the periphery of the anti-theft nut body and is movably connected at the periphery of the anti-theft nut body, and the upper end surface of the anti-theft nut body is provided with a wedge-shape mounting groove which is formed from shallow to deep along the nut mounting direction; the anti-theft nut further has an anti-theft function and can be widely applied to electric power systems, communication systems and high ways.
Description
Technical field
The utility model relates to a kind of nut, particularly 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.
Background technique
Present anti-theft nut improves on the internal structure of nut mostly, the anti-theft nut applied for of patent 200720090142.7 for example, and such nut outside is polygonal cylindricality, using screw wrench to have under the situation of collapsing force, still can turn on; The profile of the nut that has is columniform, and is the one that does not have overcoat, also can turn under the situation of using pipe wrench, so anti-theft feature needs further improvement.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of anti-theft nut of better effects if is provided.
The purpose of this utility model is achieved in that the anti-theft nut, comprise anti-theft nut body and protection outer ring, it is characterized in that: the external form of anti-theft nut body is a cylinder type, the protection outer ring 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 flexibly connects; The upper-end surface of anti-theft nut body also has along the wedge shape mounting groove of nut installation direction by shallow intensification.As preferred version: the wedge shape mounting groove is 3; Wedge shape mounting groove by shallow intensification is that groove face is from the horizontal by 20 degree angles.
The beneficial effects of the utility model are:
1, owing to adopted the upper-end surface also to have square wedge shape mounting groove structure by shallow intensification is installed, only to use special tool, has guaranteed that anti-theft nut is only with a direction rotation during installation along nut;
2, because the outside has overcoat, cannot use pipe wrench when having guaranteed to twist this nut, further increase anti-theft effect.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1; the anti-theft nut comprises anti-theft nut body 1 and protection outer ring 2, and it is characterized in that: the external form of anti-theft nut body 1 is a cylinder type; the protection outer ring 2 be an internal diameter greater than anti-theft nut body 1 external diameter tubular, can guarantee like this to protect outer ring 2 to be enclosed within the periphery of anti-theft nut body 1.
The upper-end surface of anti-theft nut body also has along the wedge shape mounting groove 4 of nut installation direction by shallow intensification, and this measure is to use when screw is installed special tool system to install along a direction.
The wedge shape mounting groove is 3; Wedge shape mounting groove 4 by shallow intensification is that groove face is from the horizontal by 20 degree angles.
