Description
Technical field
The utility model relates to mechanical links, specifically a kind of bearing pin.
Background technique
Bearing pin is the fastening piece of a class standard, both can static state be fixedly connected with, and also can do relative motion with connected piece, be mainly used in the hinged place of two parts, forms chain connection.Bearing pin locks with cotter pin usually, reliable operation, convenient disassembly.The cotter pin at bearing pin two ends often rubs, and the bearing pin of wherein one end may be caused to scurry out, have a strong impact on manufacturing efficiency.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of bearing pin, makes the cotter pin at bearing pin two ends be not easy to rub, and there will not be the bearing pin of wherein one end to scurry out.
In order to solve the problem, the technical solution of the utility model is a kind of bearing pin, comprise the footstalk connected successively, circular pillow block, first axle, second axle, 3rd axle, transition steps is provided with between first axle and the second axle, transition steps is provided with between second axle and the 3rd axle, first axle, second axle, the diameter of the 3rd axle reduces successively, pillow block is provided with the through hole of through front/rear end, pillow block is provided with the hole run through to left side from right side, latch is provided with in hole, described 3rd axle is provided with through spacing hole, described spacing hole and described through hole are parallel to each other.
Further, described footstalk and described through hole are vertical configuration, and the length of described footstalk is less than the diameter of pillow block.
Further, described transition steps conically.
Further, the sidewall of described 3rd axle is provided with the groove of two correspondences, described spacing hole penetrates into another one groove from one of them groove.
The beneficial effects of the utility model: this bearing pin adopts sectional design, and at one end adopt pillow block design, the hole on pillow block is utilized to treat link spacing, there is good position-limiting action, be not easy the bearing pin that weares and teares, there will not be the bearing pin of wherein one end to scurry out, this bearing pin simplicity of design, easy to operate, position-limiting action is good.

Embodiment
As shown in Figure 1, a kind of bearing pin, comprise the footstalk 1 connected successively, circular pillow block 2, first axle 3, second axle 4, the 3rd axle 5, transition steps 31 is provided with between first axle 3 and the second axle 4, transition steps 41 is provided with between second axle 4 and the 3rd axle 5, the diameter of the first axle 3, second axle 4, the 3rd axle 5 reduces successively, pillow block 2 is provided with the through hole 21 of through front/rear end, pillow block 2 is provided with the hole 22 run through to left side from right side, latch is provided with in hole 22,3rd axle 5 is provided with through spacing hole 51, and spacing hole 51 and through hole 21 are parallel to each other.
Conveniently control to be connected of pinned connection, being arranged to the axle direction of through hole 21 by footstalk 1 is vertical configuration, and the length of footstalk 1 is less than the diameter of pillow block 2.
Transition steps 31 is arranged conically, makes bearing pin in connection procedure, reduce damage to pin body.
In order to make spacing hole 51 have better position-limiting action, the sidewall of the 3rd axle 5 will be provided with the groove (52 of two correspondences; 53), spacing hole 51 penetrates into another one groove 53 from one of them groove 52, generally has a spacing bearing pin and passes in spacing hole, the sidewall contact place of spacing hole 51 and the 3rd axle 5 is arranged grooving, convenient fixing spacing bearing pin.
Latch is provided with a position-limited shaft in general, and position-limited shaft runs through latch, locks latch with this position-limited shaft, and so just Absorbable organic halogens lives to be connected.This bearing pin adopts sectional design, and at one end adopt pillow block design, utilizing the hole on pillow block to treat link carries out spacing, coordinate the spacing hole on the 3rd axle to carry out spacing again, there is good position-limiting action, be not easy the bearing pin that weares and teares, the bearing pin of wherein one end is there will not be to scurry out, this bearing pin simplicity of design, easy to operate, position-limiting action is good.
Above three embodiments of the present utility model have been described in detail, but described content being only the preferred embodiment that the utility model is created, the practical range created for limiting the utility model can not being considered to.All equalizations done according to the utility model creation application range change and improve, and still all should belong to patent covering scope of the present utility model.
