Abstract
The utility model relates to a shaft pin, wherein at least one end of the shaft pin is provided with a platform, and a positioning hole is formed on the platform. By arranging the platform in the proper position of the shaft pin and the positioning hole on the platform, the cross section of the position is approximately D-shaped; when the shaft pin is used in combination with a connecting part, a D-shaped hole is formed on the connecting part, in this way, the shaft pin can be clamped on the connecting part and can not rotate in case of high-speed rotation or quivering of the connecting part, resulting in low possibility of damage; in addition, a positioning shaft inserted in the shaft pin positioning hole can be prevented from undergoing excessive radial shearing force, so as to improve the reliability of the shaft pin.
Description
Technical field
The utility model relates to a kind of fastening piece, is a kind of pivot pin specifically.
Background technique
At present, in the machine part assembling, the mode that heavy embeddings such as pivot pin, straight pin, taper pin are arranged that adopts realizes the connection of positioning limit between each parts mostly.In the time need adopting pivot pin to position spacing connection because of function between link, sometimes positioning hole need be set on pivot pin, by in positioning hole, squeezing into locating stud link is fixed, when link changes in high quick-action, or during dither, wiping is wasted in the rotation that has certain amplitude in the patchhole of pivot pin on link, and aggravate with frequency quantity, pivoting friction not only can damage pivot pin but also can produce radial shear power to the locating stud in the positioning hole of pivot pin, the shear fracture that causes locating stud easily, can cause the linkage function of pivot pin unreliable like this, Security is relatively poor.
The model utility content
Technical problem to be solved in the utility model is that a kind of not fragile, comparatively reliable pivot pin is provided.
For solving the problems of the technologies described above, the utility model pivot pin, the sidewall of at least one end of pivot pin is provided with platform, and described platform place is provided with positioning hole.
After adopting above structure, the utility model compared with prior art has the following advantages:
By the appropriate location on pivot pin platform is set, and positioning hole is arranged on the platform, promptly the cross section of this position is roughly the D type, when being used with link, D type hole is set on link, like this, pivot pin will be stuck on the link, in the link high speed rotating or when shake takes place, pivot pin just can not rotate, pivot pin is not fragile, but also the positioning shaft that can avoid being inserted in the pivot pin positioning hole is subjected to excessive radial shear power, and then can improve the reliability of pivot pin.
As improvement, described platform is the radially concave station of pivot pin sidewall.So not only can reduce the size of jack on the link, be beneficial to the intensity that improves link, and can also save the consumptive material of pivot pin.

Fig. 2 is the plan view of the utility model pivot pin;
Wherein, 1, pivot pin; 2, platform; 3, positioning hole; 4, pivot pin head.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in the figure, pivot pin 1 of the present utility model, the one end is provided with pivot pin head 4, and the sidewall of the other end is provided with platform 2, and platform 2 places at sidewall left by the positioning hole 3 of this pivot pin 1, and positioning hole 3 is a radial direction through hole.This platform 2 is the radially concave station of pivot pin 1 sidewall.
Claims (2)
1. pivot pin, it is characterized in that: the sidewall of at least one end of pivot pin (1) is provided with platform (2), and described platform (2) locates to be provided with positioning hole (3).
2. pivot pin according to claim 1 is characterized in that: described platform (2) is the radially concave station of pivot pin (1) sidewall.
