Description
【Technical field】
The utility model is related to technical field of fastening, particularly a kind of anti-demounting bolt.
【Background technology】
Bolt is machine components, the cylindrical threaded fastener of adapted nut.External screw thread is carried by head and screw rod
Cylinder class fastener dimerous, need to coordinate with nut, for be fastenedly connected two carry through hole parts.This
Plant type of attachment and claim bolt connection.As nut is screwed off from bolt, the two parts can again separated, therefore bolt connection is
Belong to and be detachably connected, the bolt of prior art includes nut and screw rod, and described nut is fixedly connected with screw rod.Said structure
Bolt there is following defect during actual use：The bolt arrangement of prior art is simple, and function is single, existing spiral shell
Bolt is easy to remove bolt from object using spanner or screwdriver, causes the article that bolt is fixed by unique
People steals, for example number plate of vehicle, it is therefore necessary to propose a kind of multi-functional bolt.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of anti-demounting bolt, can be effective
Prevent bolt from arbitrarily being dismantled by other people, improve the safety and reliability that bolt is used, it is simple in construction, it is easy to use, it is easy to
Popularization and application.
To achieve the above object, the utility model proposes a kind of anti-demounting bolt, including nut, screw rod, mounting hole, dial
Bar, spring, the nut circular design a, side of the nut are fixed with screw rod, another side of the nut
Face offers two cross sections for semicircular mounting hole, and described two mounting holes are axisymmetricly distributed on nut, it is described its
In a mounting hole site it is relative in the straight flange of the upper left side of another mounting hole and two mounting holes, slide and insert in the mounting hole
The adaptable driving lever in cross section provided with cross section and mounting hole, is connected between the inner of the driving lever and the bottom of mounting hole
Spring.
Preferably, the vertical range between the straight flange of described two mounting holes is 1mm, the mounting hole in the upper left corner
Level height of the level height of bottom higher than the top of the mounting hole in the lower right corner.
Preferably, the length of the driving lever is identical with the length of mounting hole, the driving lever is located at portion more than mounting hole
Divide and be located at the spherical shape design in the back side of the straight flange of driving lever.
Preferably, the two ends of the spring are to be fixedly connected.
The beneficial effects of the utility model：The utility model is fixed with screw rod by a side in nut, in spiral shell
Another of cap offers two cross sections for semicircular mounting hole sideways, is slided in mounting hole and is inserted with cross section and peace
The adaptable driving lever in the cross section in hole is filled, spring is connected between the inner of driving lever and the bottom of mounting hole, when needs will be anti-
When stealing bolt precession object, the cutter head of straight screwdriver can be placed on between driving lever plane and screwdriver so that driving lever
The side wall of cutter head be in contact, the screwdriver that then turns right screws anti-theft bolt, when anti-theft bolt is being dismantled, by
In turn left screwdriver when, the cutter head of screwdriver can extrude the part of the spheric of driving lever so that in driving lever retraction mounting hole
Demounting bolt can not be realized, effectively can prevent other people from arbitrarily removing bolt, reliability and security that bolt is used is improved,
Compared with prior art, it can effectively prevent bolt from arbitrarily being dismantled by other people, improve the safety and reliability that bolt is used,
It is simple in construction, it is easy to use, it is easy to utilize.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
【Brief description of the drawings】
Fig. 1 is a kind of structural representation of anti-demounting bolt of the utility model.
Fig. 2 is a kind of structural side view of anti-demounting bolt of the utility model.
In figure：1- nuts, 2- screw rods, 3- mounting holes, 4- driving levers, 5- springs.
【Embodiment】
Refering to Fig. 1 and 2, a kind of anti-demounting bolt of the utility model, including nut 1, screw rod 2, mounting hole 3, driving lever 4, bullet
Spring 5, the circular design of nut 1 a, side of the nut 1 is fixed with screw rod 2, another side of the nut 1
Face offers two cross sections for semicircular mounting hole 3, and described two mounting holes 3 are axisymmetricly distributed on nut 1, described
One of mounting hole 3 is located at the upper left side of another mounting hole 3 and the straight flange of two mounting holes 3 is relative, in the mounting hole 3
Slide and be inserted with the cross section driving lever 4 adaptable with the cross section of mounting hole 3, the inner and the bottom of mounting hole 3 of the driving lever 4
Between to be connected with vertical range between spring 5, the straight flange of described two mounting holes 3 be 1mm, the mounting hole 3 in the upper left corner
Bottom top of the level height higher than the mounting hole 3 in the lower right corner level height, the length of the driving lever 4 and mounting hole 3
Length it is identical, the driving lever 4 is located at the back side spherical shape design of the part of mounting hole more than 3 and the straight flange positioned at driving lever 4,
The two ends of the spring 5 are to be fixedly connected.
Utility model works process：
A kind of anti-demounting bolt of the utility model in the course of the work, spiral shell is fixed with by a side in nut 1
Bar 2, another in nut 1 offers two cross sections for semicircular mounting hole 3 sideways, slides and plugs in mounting hole 3
There is the cross section driving lever 4 adaptable with the cross section of mounting hole 3, be connected between the inner of driving lever 4 and the bottom of mounting hole 3
