Service life, and existing piston pin using when easily come off.
Utility model content
The purpose of this utility model is easily come off to solve to exist in the prior art, and easy to wear, service life is low
The shortcomings of, and a kind of piston pin easy to use proposed.
To achieve these goals, the utility model employs following technical solution：
A kind of piston pin easy to use, including piston pin main body are designed, is offered in the middle part of the piston pin main body logical
Hole, the outer wall middle part of the piston pin main body offer three limit holes, and the limit hole is connected with through hole, three limits
Limited block is mounted in the hole of position, the limited block offers connecting hole close to one end of through hole, inserted in the connecting hole
Equipped with connecting shaft, the inner side of the through hole is installed with fixed plate close to the side of limit hole, and the piston pin main body is close
One end of through hole has been connected through a screw thread standing screw, and the through hole is provided with fixed link between standing screw and fixed plate
And spring, one end of the fixed link are flexibly connected with standing screw, the other end of the fixed link passes through spring and fixed plate
Connection, the fixed plate close to spring one end side wall last week to offering three mounting grooves, three connecting shafts respectively with
Three mounting grooves are flexibly connected.
Preferably, the limited block and limit hole are sector structure, and limit hole, limited block are outside piston pin main body
One end cross-sectional area size of wall is identical.
Preferably, the standing screw is interior hexagonal standing screw.
Preferably, the both ends of the spring are fixedly connected with fixed link, fixed plate respectively.
The utility model proposes a kind of piston pin easy to use, beneficial effect is：By in limited block by piston
Pin main body is fixed on the junction of piston and connecting rod, can reduce wrist pin wear, the risk of destruction be reduced, by through hole
Fixed link is set, and limited block is flexibly connected by connecting shaft with fixed link, coordinates fixed link to drive using standing screw, spring
Dynamic limited block movement, is easily installed, and the utility model is simple in structure, and convenient installation and dismounting, good fixing effect being capable of anti-anti-avulsion
Worn when falling, and piston pin can be avoided to use, reduce the risk of destruction, while improve the service life of piston pin.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of piston pin easy to use structure diagram；
Fig. 2 be the utility model proposes a kind of piston pin easy to use structural side view.
In figure：Piston pin main body 1, through hole 2, fixed link 3, limited block 4, fixed plate 5, screw thread 6, standing screw 7, connecting hole
8th, connecting shaft 9, limit hole 10, spring 11, mounting groove 12.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
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.
With reference to Fig. 1-2, a kind of piston pin easy to use, including piston pin main body 1, the middle part of piston pin main body 1 open up
There is through hole 2, three limit holes 10 are offered in the middle part of the outer wall of piston pin main body 1, limit hole 10 is connected with through hole 2, three limits
Limited block 4 is mounted in the hole 10 of position, limited block 4 and limit hole 10 are sector structure, and limit hole 10, limited block 4 are close
One end cross-sectional area size of 1 outer wall of piston pin main body is identical, in use, limited block 4 can be avoided to come off, ensures piston and company
The stability of bar connection, at the same when piston pin can be avoided to use wear, raising service life.
Limited block 4 offers connecting hole 8 close to one end of through hole 2, and connecting shaft 9, through hole 2 are inserted with connecting hole 8
Inner side be installed with fixed plate 5 close to the side of limit hole 10, piston pin main body 1 passes through screw thread 6 close to one end of through hole 2
Standing screw 7 is connected with, through hole 2 is provided with fixed link 3 and spring 11, fixed link 3 between standing screw 7 and fixed plate 5
One end be flexibly connected with standing screw 7, the other end of fixed link 3 is connected by spring 11 with fixed plate 5, the both ends of spring 11
Be fixedly connected respectively with fixed link 3, fixed plate 5, fixed plate 5 close to spring 11 one end side wall last week to offering three installations
