Description
Background technology
The utility model is related to a kind of oilless air compressor, specially a kind of connecting rod piston of oilless air compressor.
Background technology
Currently, the connecting rod piston of existing oilless air compressor is an integral structure, piston crown is provided with leather cup and gas
Cylinder is tightly connected, and piston tail is movably hinged with eccentric mechanism.In use, one is driven by the rotation of eccentric mechanism
Formula piston telescopic oscillating works, to make leather cup in the cylinder stretch work while swung.
There is very big problem, the contact surface of one side leather cup and cylinder in the above unitary link piston structure and working method
It is smaller, cause the leakproofness of the two poor, it is difficult to obtain higher operating air pressure；While another aspect leather cup is flexible into
Row swing, leads to the side excessive compression cylinder wall of leather cup and cylinder wall is deviateed in the other side, which not only be easy to cause
The Fast Wearing of leather cup, reduces the service life, the most important leakproofness affected between leather cup and cylinder, is easy at work
Gas leak phenomenon occurs, has seriously affected the service pressure of piston.
Utility model content
In view of the above-mentioned problems, the utility model devises a kind of connecting rod piston of oilless air compressor, seperated activity is used
Hinged piston structure can effectively promote the sealing performance of piston and cylinder, prolong the service life, and improve the work pressure of piston
Power.To achieve the above object, the utility model uses following technical scheme：
A kind of connecting rod piston of oilless air compressor, it is characterised in that：Including piston head and piston rod, set at the top of piston head
It is equipped with the leather cup that can be connect with cylinder seal, piston tail end is movably hinged with piston rod, piston rod tail portion and eccentric wheel
Mechanism is flexibly connected.
Further, above-mentioned leather cup is located in piston head top by a gland.
Further, above-mentioned piston head outer wall is provided at least one of oil-free piston ring below leather cup.
Further, above-mentioned piston head outer wall is provided with mounting groove below oil-free piston ring, is provided with and leads in mounting groove
Xiang Huan.
Further, above-mentioned piston head-tail is provided with a mounting hole and one and perpendicular to mounting hole and penetrates through entire piston head
The axis hole of side wall；The head in piston rod band connection hole is extend into the mounting hole, and by axis pin in axis hole with
The connecting hole flexible connection.
Further, the connecting hole Tong Guo Roll needle bearings of above-mentioned piston rod are flexibly connected with axis pin, needle bearing both sides
It is provided with close trim ring.
The connecting rod piston of the utility model design is made of the piston head and piston rod being movably hinged, and at work, is led to
The rotation for crossing eccentric mechanism drives piston rod to swing, and is movably hinged herein because piston head is seperated with piston rod, piston
The eccentric swing of connecting rod is not transferred on piston head, and only opposite cylinder does axial stretching movement, the movement side to entire piston head
Formula will not cause the swing of leather cup to wear, and can effectively extend the service life of leather cup, promote the connection sealing of leather cup and cylinder,
The operating pressure for promoting piston, makes oilless air compressor meet the need of work of higher pressure.
Description of the drawings

Specific implementation mode
As shown in Figs. 1-3, a kind of connecting rod piston of oilless air compressor, including piston head 1 and piston rod 2, piston head 1 push up
Portion is provided with the leather cup 3 that can be connect with cylinder seal, and leather cup 3 is located in 1 top of piston head by a gland 31.
1 tail end of piston head is movably hinged with piston rod 2.In this diagram, 1 tail portion of piston head is provided with a mounting hole 11
Perpendicular to mounting hole and the axis hole 12 of entire piston head side wall is penetrated through with one.It stretches on the head in 2 band connection hole 21 of the piston rod
Enter into the mounting hole 11, and be flexibly connected with the connecting hole 21 by the axis pin 13 in axis hole 12, and then realizes piston
First 1 with the living hinge of piston rod 2, other articulated structures can also be used in practice.
Here, for that can promote piston head 1 and the hinged flexibility of piston rod 2, the connecting hole 21 of the piston rod 2 is logical
Roll needle bearings 22 of Guoing are flexibly connected with axis pin 13, and needle bearing both sides are provided with close trim ring 23, needle bearing 22 and close trim ring 23
It is interior to be equipped with fire-resistant lubricants, to meet the need of work of piston high temperature and pressure.
2 tail portion of the piston rod is flexibly connected with eccentric mechanism 4.
The connecting rod piston of the above structure is made of piston head 1 and piston rod 2 combination being movably hinged, and at work, is led to
The rotation for crossing eccentric mechanism 4 drives piston rod 2 to swing, and is movably hinged herein because piston head 1 is seperated with piston rod 2,
The eccentric swing of piston rod 2 is not transferred on piston head 1, and the opposite cylinder of entire piston head 1 does stretching motion, the movement
Mode will not cause the swing of leather cup 3 to wear, and can effectively extend the service life of leather cup 3, promote the company of leather cup 3 and cylinder
Leakproofness is connect, the operating pressure of piston is promoted, oilless air compressor is made to meet the need of work of higher pressure.
1 outer wall of the piston head is provided at least one of oil-free piston ring 5 below leather cup 3, can further promote work
Sealing performance between chock plug 1 and cylinder can make oilless air compressor meet the need of work of higher pressure.
