A kind of automobile rubber diaphragm

Abstract

The invention discloses an automobile rubber diaphragm leaf comprising a sealing bowl body. The periphery of the top surface of the sealing bowl body is fixedly connected to a fixed limit sleeve, andsealing blocks are uniformly distributed and arranged on the outside surface of the sealing bowl body from top to bottom in a sleeved manner; and the surface of each sealing block is provided with a first sealing ring in a sleeving manner, and the middle position of the bottom of an inner cavity of the sealing bowl body is fixedly connected to a fixed connecting rod. The invention relates to the technical field of automobile rubber diaphragm leaves. According to the automobile rubber diaphragm pad, the purpose of wide application is achieved, and the sealing bowl body is similar to an invertedcone; openings of different diameters can be sealed effectively through the sealing blocks of different specifications arranged on the outside surface of the sealing bowl body, and the use is relatively convenient; impact force on the sealing bowl body can be reduced through damping springs effectively, so that the sealing bowl body is prevented from loosing at the opening to be sealed or directly falling from the opening to be sealed; and the automobile rubber diaphragm leaf benefits improvement of the overall sealing effect and prolonging of the service life.

Description

technical field [0001] The invention relates to the technical field of automobile rubber diaphragm equipment, in particular to an automobile rubber diaphragm. Background technique [0002] Diaphragm is the main part of diaphragm pump products. Diaphragm has three series: composite diaphragm, rubber diaphragm and PTFE diaphragm. There are different materials to choose from. Diaphragm transmission is a kind of transmission of pressure energy and mechanical movement to pneumatic diaphragm by means of diaphragm. Inside the pump, in the form of a fully enclosed seal for transporting and compressing fluid or driving parts, the reciprocating motion can be transmitted to the cylinder through the flexible diaphragm, and the diaphragm moves to inhale, compress and exhaust. The selection of the diaphragm material is mainly determined by the pump. The nature, pressure and temperature of the sealed fluid, etc. The overall design of the diaphragm should take into account the movement mode...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automobile rubber diaphragm, which solves the problem that the existing automobile rubber diaphragm is fixed in shape and diameter, so generally a single rubber diaphragm is only suitable for one type of opening so that it can be Therefore, the scope of application of this type of rubber diaphragm is small, and it is inconvenient to use, and the surface of the existing rubber diaphragm is prone to friction and impact during use, and it is easy to fall off from the opening to be sealed, and it is easy to seal the opening. It is not strictly necessary for the leakage of liquid and the damage of the diaphragm in the process of impact and friction, which is not conducive to prolonging its service life.
