Description
Technical field
This utility model is related to a kind of machine tooth screw, more particularly to a kind of cross bilayer pivot pin machine tooth screw.
Background technology
Screw is the physicss of the inclined-plane circular rotating and frictional force using object and mathematical principle, is fastened by easy stages
The instrument of implements parts.Screw is the general saying of securing member, daily pet phrase.Screw is work indispensable in daily life
Industry necessary：The minimum screw that such as photographing unit, glasses, clock and watch, electronics etc. are used；TV, electric product, musical instrument, furniture etc.
General screw；Large-scale screw, nut are used then as engineering, building, bridge；Traffic tool, aircraft, electric car, automobile etc. are then
It is used in combination for big primary screw.Screw industrially bears vital task, as long as industry is there is on the earth, then the function of screw is eternal
It is important.Screw is joint invention over the past thousands of years in people's productive life, and from the point of view of application, it is the first big of the mankind
Invention, traditional screw are used for fixing workpiece, play fastening effect, but cannot function as pivot pin use, single function, in dismounting
Can not quick-detach soon, using not enough facilitating, affect the work efficiency of staff.
Utility model content
The utility model proposes a kind of cross bilayer pivot pin machine tooth screw, solves screw function list in prior art
One, it is impossible to enough to use as pivot pin, the problem that fixed workpiece is not sufficiently stable makes the function of screw more comprehensive, uses more
Plus convenience.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme：
A kind of cross bilayer pivot pin machine tooth screw of this utility model, including screw rod and screw terminal, the top of the screw rod
It is fixedly connected with the screw terminal by stressed member, on the outer wall of the screw rod, is fixed with thread, the top of the screw terminal
Straight-tooth is fixed with, the top of the screw terminal is fixed with installation notch.
Surface fixation as a kind of optimal technical scheme of the present utility model, the screw rod and the screw terminal is electroplate with
Zinc.
Used as a kind of optimal technical scheme of the present utility model, the surface of the straight-tooth is polished polishing.
As a kind of optimal technical scheme of the present utility model, groove of the installation notch for cross-type.
The beneficial effect reached by this utility model is：The scope that this utility model is used is more extensive, it is adaptable to different
The workpiece of diameter, using convenient so that more consolidate between screw body and workpiece, it is using safer, solid by being provided with
Dead axle, enables to stablize between each axis body so that using convenient, and overall structure is simple, cheap, practicality
By force, it is easy to promote.
Description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and constitutes a part for description, with this practicality
New embodiment is used for together explaining this utility model, does not constitute to restriction of the present utility model.In the accompanying drawings：
Fig. 1 is subjective structural representation of the present utility model；
In figure：1st, screw rod；2nd, stressed member；3rd, screw terminal；4th, straight-tooth；5th, installation notch.
Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
Embodiment 1
As shown in figure 1, this utility model provides a kind of cross bilayer pivot pin machine tooth screw, including screw rod 1 and screw terminal
3, the top of screw rod 1 is fixedly connected with screw terminal 3 by stressed member 2, and thread 6, screw terminal 3 are fixed with the outer wall of screw rod 1
Top be fixed with straight-tooth 4, the top of screw terminal 3 is fixed with installation notch 5.
Further, the surface of screw rod 1 and screw terminal 3 is fixed and is electroplate with zinc, can play a protective role, and prevents rust
Change, be easy to increase the usage cycles of cross bilayer pivot pin machine tooth screw.
The surface of straight-tooth 4 is polished polishing, can effectively remove the burr on straight-tooth 4, prevent prick into human body.
Installation notch 5 are the groove of cross-type, facilitate personnel to mount and dismount, and are easy to use.
The scope that this utility model is used is more extensive, it is adaptable to the workpiece of different-diameter, using convenient so that spiral shell
More consolidate between silk body and workpiece, use is safer, and by being provided with fixing axle, enabling to can be steady between each axis body
Fixed so that using convenient, overall structure is simple, cheap, practical, it is easy to promote.
Finally it should be noted that：Preferred embodiment of the present utility model is the foregoing is only, this is not limited to
Utility model, although being described in detail to this utility model with reference to the foregoing embodiments, for those skilled in the art
