Abstract
The utility model discloses a kind of two-way bolt, including bolt head and screw rod, screw rod at least includes two screw rod joints, diameter between screw rod joint is laterally away from bolt head side by close bolt head one and tapers into, being provided with transition region between screw rod joint, the diameter of transition region is between the diameter of adjacent two screw rods joint.This utility model carries out mild transition by the diameter that adjacent screws is saved by transition region, thus the intensity between lift-bolt joint.
Description
Technical field
This utility model relates to a kind of two-way bolt.
Background technology
Nowadays on market, the model of bolt is various, when the bolt failure of a kind of model, is necessary for using same model
Bolt, the bolt of possible this model is just finished, it is necessary to going out to buy, bring unnecessary trouble, the impact connect produces effect
Rate.Nowadays on market, the screw rod of a bolt usually cylinder is threaded, when two machine components location hole size not
For the moment, bolt in the market cannot meet requirement.
For the problems referred to above, Chinese patent: a kind of special shaped screw bolt (patent No. 201120460523.6) provides a kind of platform
The bolt arrangement of stepwise solves this problem, but this special shaped screw bolt is owing between the adjacent step of screw rod, the transition of diameter is more
Precipitous, cause screw rod intensity between adjacent step the highest, be easily broken off.
Utility model content
The purpose of this utility model is to solve posed problems above, it is provided that a kind of solve the double of the highest problem of above-mentioned intensity
To bolt.
The technical solution of the utility model is such that
A kind of two-way bolt, including bolt head and screw rod, described screw rod at least includes two screw rod joints, and described screw rod saves it
Between diameter be laterally away from bolt head side taper into by near bolt head one, be provided with transition region between described screw rod joint,
The diameter of described transition region is between the diameter of adjacent two screw rods joint.
The diameter saved adjacent screws by transition region carries out mild transition, thus strong between lift-bolt joint
Degree.
As preferably, between the two ends of described transition region and adjacent screws joint, it is respectively arranged with chamfering.
Chamfering can not only make there is a mild transition, meanwhile, at screw rod between the screw rod joint that transition region is adjacent
The effect of guiding is also played during use.
As preferably, the thickness of described transition region is 1～2 times of the pitch of the adjacent screw rod being relatively large in diameter joint.
As preferably, described screw rod joint is three.
This utility model carries out mild transition by the diameter that adjacent screws is saved by transition region, thus lift-bolt saves
Between intensity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure:
1. bolt head, 2. screw rod joint, 3. transition region, 4. chamfering.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described in further detail:
Embodiment 1
As it is shown in figure 1, a kind of two-way bolt, including bolt head 1 and screw rod, screw rod includes two screw rod joints 2, screw rod joint 2
Between diameter be laterally away from bolt head 1 side taper into by near bolt head 1 one, be provided with transition region between screw rod joint 2
3, the diameter of transition region 3, between the diameter of adjacent two screw rods joint 2, divides between the two ends of transition region 3 and adjacent screws joint 2
Not being provided with chamfering 4, the thickness of transition region 3 is 1～2 times of the pitch of the adjacent screw rod being relatively large in diameter joint 2.
This utility model carries out mild transition by transition region 3 to the diameter of adjacent screws joint 2, simultaneously with chamfering 4
Combining, improve the intensity between screw rod joint 2, chamfering 4 also has guide effect, efficiently solves adjacent when bolt screws
Screw rod saves the problem that the intensity between 2 is the highest.
Claims (4)
1. a two-way bolt, including bolt head (1) and screw rod, described screw rod at least includes two screw rods joint (2), described screw rod
Diameter between joint (2) is laterally away from bolt head (1) side by close bolt head (1) and tapers into, it is characterised in that described
Be provided with transition region (3) between screw rod joint (2), the diameter of described transition region (3) between adjacent two screw rods joint (2) diameter it
Between.
Two-way bolt the most according to claim 1, it is characterised in that the two ends of described transition region (3) are saved with adjacent screws
(2) chamfering (4) it is respectively arranged with between.
Two-way bolt the most according to claim 1 and 2, it is characterised in that the thickness of described transition region (3) is adjacent straight
1～2 times of the pitch of screw rod joint (2) that footpath is bigger.
Two-way bolt the most according to claim 3, it is characterised in that described screw rod joint (2) is three.
