Abstract
The utility model discloses a kind of straight pin, including cylindrical body, the cylindrical body side end face is opened up there are two the fixing groove being symmetric, and the cylindrical body side end face offers through-hole, and through-hole runs through cylindrical body, and the through-hole is provided with fixing groove bottom end.Hexagon socket head cap screw is put into through-hole, hexagon socket head cap screw head comes into full contact with fixing groove, after bolt is contacted with connector, connector is come into full contact with by fixing groove and straight pin, can play anti-skidding effect, good fixing effect, drive straight pin come back rotation, good practical effect by connector.Currently, existing straight pin practical function is bad in the market, antiskid effect and fixed effect are bad.The purpose of this utility model is to provide a kind of straight pin, increase fixing groove, solves that existing equipment practical function is bad, antiskid effect and the bad problem of fixed effect.
Description
Technical field
The utility model relates to technical field of hardware, specially a kind of straight pin.
Background technique
Pin can also be used as the part of safety device, cylinder generally to couple, lock part or be used as assembly positioning
Pin is fixed in hole by interference, to retaining element, transmitting power, or makees locating piece.
Straight pin is mainly used for positioning, it can also be used to connect, he is fixed in pin hole by interference fit.Straight pin is used
It is to be generally free from load or by the load of very little, quantity is no less than two in positioning, it is integrally-built is distributed in connected piece
It is more remoter better apart on symmetry direction, sell 1-2 times that the length in each connected piece is about minor diameter.
Straight pin can also do axis use, and a d-axis can also do straight pin, even centring pin.Axis can be used to transmit
Torque bears moment of flexure and torque, and straight pin is used to position, and bears extruding force and shearing force, in some sense for it is (such as small-sized to set
It is standby), straight pin can also do axis use.
It is raw material manufacture that straight pin applies carbon constructional quality steel more at present.Under normal circumstances, material multiselect C35,
C45, but must be heat-treated.High intensity requires lower selection bearing steel.
Positioning pin is generally free from or only by the load of very little, size is often determined by experience, connection be often squeezed with pin and
Shearing, but then the size sold can make corresponding strength check by stress condition according to coupling structure feature and empirically determined, pacify
The strength condition that full pin diameter is cut when should be by overload determines.
Currently, existing straight pin practical function is bad in the market, antiskid effect and fixed effect are bad.
Summary of the invention
The purpose of this utility model is to provide a kind of straight pins, increase fixing groove, solve the practical effect of existing equipment
Fruit is bad, antiskid effect and the bad problem of fixed effect.
To achieve the above object, the utility model provides the following technical solutions: a kind of straight pin, including cylindrical body, described
Cylindrical body side end face is opened up there are two the fixing groove being symmetric, and the cylindrical body side end face offers through-hole, and through-hole passes through
Cylindrical body is worn, the through-hole is provided with fixing groove bottom end.
Preferably, the terminal pad is with a thickness of 1.05mm, diameter 13.7mm.
Preferably, the cylinder diameter is 12mm.
Preferably, the through-hole length is 9mm, and diameter is 8.1mm.
Preferably, the fixing groove diameter is 12.6mm.
Preferably, straight pin total length is 23mm.
Compared with prior art, the beneficial effects of the utility model are as follows:
Hexagon socket head cap screw is put into through-hole, hexagon socket head cap screw head comes into full contact with fixing groove, and bolt is contacted with connector
Afterwards, connector is come into full contact with by fixing groove and straight pin, can play anti-skidding effect, good fixing effect, by connector band
Dynamic straight pin comes back rotation, good practical effect.
Detailed description of the invention
Fig. 1 is the side view of the utility model main body；
Fig. 2 is the top view of the utility model main body.
In figure: 1- fixing groove, 2- terminal pad, 3- cylindrical body, 4- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-2 please be read, the utility model provides a kind of technical solution: a kind of straight pin, including cylindrical body 3,3 side of cylindrical body
End face is opened up there are two the fixing groove 1 being symmetric, and 3 side end face of cylindrical body offers through-hole 4, and through-hole 4 runs through cylindrical body
3, through-hole 4 is provided with 1 bottom end of fixing groove.
Terminal pad 2 is 12mm with a thickness of 1.05mm, diameter 13.7mm, 3 diameter of cylindrical body, and 4 length of through-hole is 9mm, and
Diameter is 8.1mm, and 1 diameter of fixing groove is 12.6mm, and straight pin total length is 23mm.
Working principle: in use, hexagon socket head cap screw is put into through-hole 4, hexagon socket head cap screw head sufficiently connects with fixing groove 1
Touching, after bolt is contacted with connector, connector is come into full contact with by fixing groove 1 with straight pin, can play anti-skidding effect, Gu
It is good to determine effect, drives straight pin come back rotation, good practical effect by connector.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
