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 nut with anti-theft feature of fastenings or member.
Background technique
The anti-theft nut comprises nut body and protecting jacket, and protecting jacket is enclosed within the outside of nut body, and in the prior art, nut body inside has antitheft pin block or tapering spring, and such nut has manufacture cost height, baroque shortcoming.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, and a kind of nut with anti-theft feature of simple in structure, low cost of manufacture is provided.
The purpose of this utility model is achieved in that the nut with anti-theft feature; comprise nut body and protecting jacket; protecting jacket is enclosed within the outside of nut body; the nut body upper-end surface has along tightening the tighten groove of direction by shallow intensification, and it is characterized in that: nut body inside is complete screw structural.
Say that further described protecting jacket outside is columned.
Say further that perhaps described protecting jacket outside is a prism-shaped, the outside that described protecting jacket is enclosed within nut body is also bonding by glue.
The beneficial effects of the utility model are: such nut with anti-theft feature has simple in structure, advantage of low manufacturing cost.
Description of drawings
Fig. 1 is the structural representation with nut of anti-theft feature of the present utility model
Wherein, 1, nut body 2, protecting jacket 3, tighten groove 4, complete screw
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1; nut with anti-theft feature comprises nut body 1 and protecting jacket 2, and protecting jacket 2 is enclosed within the outside of nut body 1; nut body 1 upper-end surface have along tighten direction by shallow intensification tighten groove 3, it is characterized in that: nut body 1 inside is complete screw 4 structures.Complete screw structural described here is meant: the screw lines of nut body inside is uninterrupted from the bottom to the top, does not pacify the groove of shape tapering piece or tapering spring in nut body.
Say that further described protecting jacket outside is columned, can install tightening on the groove during installation that protecting jacket can be antitheft.
Say further that perhaps described protecting jacket outside is a prism-shaped, the outside that described protecting jacket is enclosed within nut body is also bonding by glue.During installation, twist outside prism with spanner in certain scope, reach certain degree, bonding glue cracking perhaps continues to tighten tightening groove, reaches antitheft effect.
