Abstract
The utility model provides an one -wayly prevent tearing open bolt, includes: screw and nut, be equipped with a breach on the top screw thread of screw, be equipped with the block tongue in the breach, have elastomeric element in the block tongue, the screw uses with the nut cooperation, has nut groove on the nut. The utility model discloses a structural design is novel unique, and simple installation, the screw suite after the installation are under the effect of strong spring, and in the bolt block tongue top embedding nut groove, during clockwise rotation, the block tongue quits the draw -in groove under inner wall of nut pressure, and the screw is further screwed, and rotated counter -clockwise is not worked as to the affect using, and under the effect of strong spring, the block tongue prevents that the bolt from separating the get loose in enterring nut groove rapidly.
Description
Technical field
This utility model is related to a kind of bolt, it is adaptable to power domain, relates generally to electric power line pole tower, bracing wire closely
When the connection in face, fastening or a kind of power equipment can not be opened, disengaging section is used device.More particularly to a kind of unidirectional tamper
Bolt.
Background technology
In the mid ＆ low-voltage line of current distribution, steel tower, line bar is typically all adopted to set up, the connection of iron tower component, line bar
Assorted golden tool etc. can all be related to connecting screw, and existing screw both can be tightened with forward direction, reversely can be released again, just
Screw dismounting under often maintenance, maintenance plan, does not result in steel tower, line bar and topples over normal operation with power equipment, once meet with
Meet the artificial dismounting and destruction of unplanned property, it will pole is brought to power circuit, the normal operation of power equipment and personal safety
The earth endangers.
The content of the invention
The shortcoming of prior art in view of the above, the purpose of this utility model are to provide a kind of unidirectional dismounting-proof bolt,
For solving problems of the prior art.
For achieving the above object and other related purposes, this utility model provides a kind of unidirectional dismounting-proof bolt, including：
Screw and nut, the top screw thread of the screw are provided with a breach, are provided with block tongue in breach, flexible in block tongue
Part；Screw is used with nut screw connection, has nut draw-in groove on nut.
Preferably, the breach is sector structure.
Preferably, the mouth is identical with the structure of block tongue.
Preferably, there is a vertical stile on the nut draw-in groove.
Preferably, the elastomeric element is spring.
Preferably, the elastomeric element is located at the clockwise initial end of screw.
Preferably, the structure of the nut draw-in groove is triangle.
As described above, this utility model has the advantages that：
Novel in structural design of the present utility model is unique, simple installation, work of the screw external member after installation in brute spring
With under, in the inserted num draw-in groove of bolt block tongue top, when turning clockwise, block tongue exits draw-in groove, spiral shell under nut inner wall pressure
Silk is further screwed, and does not affect to use, and when rotating counterclockwise, in the presence of brute spring, block tongue quickly enters nut card
In groove, prevent bolt from separating and release.

Refer to Fig. 1 to Fig. 3.It should be noted that the diagram provided in the present embodiment only illustrates this in a schematic way
The basic conception of utility model, when only showing then the component relevant with this utility model in schema rather than implementing according to reality
Component count, shape and size are drawn, and during its actual enforcement, the kenel of each component, quantity and ratio can change for a kind of random
Become, and its assembly layout kenel be likely to it is increasingly complex.
This utility model provides a kind of unidirectional dismounting-proof bolt, including：
Screw 1 and nut 4, cut one piece of screw 1 on the top screw thread of the screw 1, form breach 2, set in breach 2
There is block tongue 3,5 spring of flexible part in block tongue 3；Screw 1 is used cooperatively with nut 4, has nut draw-in groove 6 on nut 4.
In one embodiment of this utility model, the breach 2 is sector structure, and breach 2 is identical with the structure of block tongue 3.
Have a vertical stile 7 in one embodiment of this utility model, the nut draw-in groove 6, in case bolt block tongue bolt,
It is embedded when nut is closed.
In one embodiment of this utility model, 5 spring of the elastomeric element is located at the clockwise initial end of screw.Herein
For the clockwise direction said is the putting position based on bolt, bolt is vertically to put, with screw thread end upper.
In one embodiment of this utility model, the structure of the nut draw-in groove 6 is triangle.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art all can be carried out to above-described embodiment under without prejudice to spirit and the scope of the present utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in this utility model
All equivalent modifications completed under god and technological thought or change, should be covered by claim of the present utility model.
