To better illustrate the objects, aspects and advantages of the present invention, the present invention will be further described with reference to specific embodiments. The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art, and the present invention will only be defined by the appended claims.

As shown in fig. 1-3, the utility model provides a leather cup formula pneumatic hydraulic pump, including pump

main part

2, 2 upper portions of pump main part are out water section 21, and the position that goes out water section 21 and be close to the delivery port is equipped with delivery port check

valve sheet rubber

3, and 2 lower parts of pump main part are into water section 22, and section 22 lateral walls of intaking is equipped with the water inlet, and the position that is close to the water inlet is equipped with water inlet check valve sheet rubber 8. The water outlet one-way valve rubber sheet 3 and the water inlet one-way valve rubber sheet 8 can be opened or tightly attached to the inner wall of the pump main body to form sealing due to pressure.

The cylinder 1 is arranged below the pump main body 2, the cylinder 1 is provided with an automatic reversing pneumatic reversing valve 11, the free end of the cylinder 1 penetrates through a lower cover plate of the pump main body 2 and extends into an inner cavity of the pump main body 2, the free end of the cylinder 1 is provided with a supporting sleeve 7, a leather cup 6 is fixed on the supporting sleeve 7 through a locking structure, the outer edge of the leather cup 6 abuts against the inner side wall of the pump main body 2, and the opening of the leather cup 6 can be opened outwards or contracted inwards along with the change of the pressure intensity of the upper end and the lower end.

In above technical scheme, leather cup 6 is the bowl form structure that the bottom was equipped with the through-hole, and supporting sleeve 7 top is equipped with two preforming 5, and leather cup 6 passes through two preforming 5 and locking screw 4 to be fixed on supporting sleeve 7 and can reciprocate along with the free end of cylinder 1.
