Description
Technical field
The present invention relates to piston technical field, more particularly to a kind of piston pin easy to use.
Background technology
Piston component includes piston, piston ring, piston pin.Piston pin is the key part for connecting piston and connecting rod, its
Effect is that the gas pressure on piston and inertia force are passed to connecting rod by key seat and piston pin, so as to complete kinetic energy to heat energy
Conversion, existing piston pin when in use, easily rocks in the junction of piston and connecting rod, causes wrist pin wear, reduces
Service life, and existing piston pin using when easily come off.
The content of the invention
The invention aims to solve to exist in the prior art easily to come off, easily abrasion, the low grade of service life lack
Point, and a kind of piston pin easy to use proposed.
To achieve these goals, present invention employs following technical scheme：
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 spacing holes, and the spacing hole connects 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
Provided with connecting shaft, the inner side of the through hole is installed with fixed plate close to the side of spacing 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 fix bar between standing screw and fixed plate
And spring, one end of the fix bar are flexibly connected with standing screw, the other end of the fix bar passes through spring and fixed plate
Connection, the fixed plate circumferentially offer three mounting grooves in one end side wall of spring, three connecting shafts respectively with
Three mounting grooves are flexibly connected.
Preferably, the limited block and spacing hole are sector structure, and spacing 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 fix bar, fixed plate respectively.
A kind of piston pin easy to use proposed by the present invention, beneficial effect are：By in limited block by piston pin master
Body is fixed on the junction of piston and connecting rod, can reduce wrist pin wear, reduces the risk of destruction, by being set in through hole
Fix bar, and limited block is flexibly connected by connecting shaft with fix bar, coordinate fix bar driving limit using standing screw, spring
Position block movement, is easily installed, and the present invention is simple in construction, convenient installation and dismounting, good fixing effect, can prevent from coming off, and
Worn when 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 is a kind of structural representation of piston pin easy to use proposed by the present invention；
Fig. 2 is a kind of structural side view of piston pin easy to use proposed by the present invention.
In figure：Piston pin main body 1, through hole 2, fix bar 3, limited block 4, fixed plate 5, screw thread 6, standing screw 7, connecting hole
8th, connecting shaft 9, spacing hole 10, spring 11, mounting groove 12.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Reference picture 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 spacing holes 10 are offered in the middle part of the outer wall of piston pin main body 1, spacing hole 10 connects with through hole 2, three limits
Limited block 4 is mounted in the hole 10 of position, limited block 4 and spacing hole 10 are sector structure, and spacing hole 10, limited block 4 are close
One end cross-sectional area size of the outer wall of piston pin main body 1 is identical, in use, limited block 4 can be avoided to come off, ensures piston and company
The stability of bar connection, while wear when piston pin can be avoided to use, 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 spacing 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 fix bar 3 and spring 11, fix bar 3 between standing screw 7 and fixed plate 5
One end be flexibly connected with standing screw 7, the other end of fix bar 3 is connected by spring 11 with fixed plate 5, the both ends of spring 11
It is fixedly connected respectively with fix bar 3, fixed plate 5, fixed plate 5 circumferentially offers three installations in one end side wall of spring 11
