Description

Miniature water pump leather cup Technical Field The utility model relates to the technical field of piston sealing elements, in particular to a miniature water pump leather cup. Background The packing cup in the piston type water pump is an important sealing piece, and the packing cup is wrapped and installed on the edge of the piston, so that the piston can reciprocate to form a sealing cavity, water or medium is prevented from leaking between the piston and the pump barrel, and water absorption and drainage efficiency is ensured. The existing patent application number 202420823477.9 is a wear-resistant leather cup for sewage treatment, which comprises a leather cup body, a wear-resistant layer and a substitution layer, wherein the leather cup body comprises a sealing part and a cup bottom, the sealing part comprises the wear-resistant layer, and the substitution layer is arranged on the outer side of the wear-resistant layer. The above patent describes a sealing member for a leather cup, in which the leather cup is usually made of rubber material in the practical application process, and the rubber material of the leather cup is aged after long-time use, so that the elasticity of the rubber cup is weakened, and thus the sealing member cannot maintain effective sealing, and the functional structure of the leather cup can be further perfected, so that the sealing durability of the leather cup is enhanced, and the replacement period is prolonged. Disclosure of utility model The utility model aims to provide a miniature water pump leather cup to solve the problems in the background technology. In order to achieve the purpose, the technical scheme is that the miniature water pump leather cup comprises an inner support leather cup, wherein the inner support leather cup comprises a leather cup main body, a leather cup inner cavity, an assembly hole, a limiting ring part and a support ring, the leather cup inner cavity is formed in the leather cup main body, the leather cup inner cavity is an open cavity, the assembly hole is formed in the middle of the bottom surface of the leather cup inner cavity, the assembly hole penetrates through the bottom of the leather cup main body, the upper part of the inner wall surface of the leather cup inner cavity is integrally provided with the limiting ring part, the support ring is nested in the leather cup inner cavity, and the installation height of the support ring is lower than that of the limiting ring part. Preferably, the whole supporting ring is made of stainless steel. Preferably, the outer surface of the supporting ring is designed into a cambered surface. Preferably, the surface of the supporting ring is cut off and provided with a notch. Preferably, the outer surface of the support ring is provided with anti-skid patterns. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the inner support leather cup is arranged, the support ring is pressed to force the inner support leather cup to shrink the size structure of the inner support leather cup, then the support ring is embedded and plugged into the inner cavity of the leather cup, then the support ring recovers the elastic deformation shape and is restored, and at the moment, the support ring is abutted against the inner wall of the inner cavity of the leather cup to provide internal support for the main body of the leather cup, so that the main body of the leather cup is kept in an expanded state, the inward collapse caused by the loss of elasticity due to the aging of materials is avoided, the structural shape stability of the main body of the leather cup can be enhanced, and the sealing durability is enhanced. According to the utility model, the surface of the support ring is cut off to be provided with the notch, and the support ring can shrink the size structure of the support ring through the notch, so that the support ring can be embedded and plugged into the inner cavity of the leather cup, and the assembly is easy.
