Problems solved by technology

[0003] Due to the defects in the design of the existing pump system, the components that make up the pump system cannot be made into standard components, and pump systems with different functions cannot be assembled by replacing components, which undoubtedly increases the cost of mold opening, and requires different assembly equipment for assembly also increases assembly cost

Abstract

The invention discloses a locking cover of a standardized screw-tooth lock liquid distribution pump, which includes a locking cover body. Internal threads, a connection hole is provided in the middle of the locking cover body, a positioning step is provided between the outer wall of the lower end of the connecting part and the locking cover body, and a clamping part is provided outside the locking cover body. The purpose of the present invention is to overcome the disadvantages of the prior art, and provide a screw locking cap which is simple in structure, easy to use and can be used as a standardized component. When the standardized screw locking cover of the present invention is applied, it can be assembled with a standardized pump chamber, which can realize standardized production and reduce mold opening costs, and can be assembled by the same assembly machine, thereby effectively reducing production costs.

Description

Technical field [0001] The invention relates to a standardized screw lock liquid distribution pump locking cover. Background technique [0002] At present, many products such as liquids, creams and hair gels are distributed by pump systems. These pump systems are generally produced with specific designs. It is impossible to assemble pump systems with different functions by changing accessories, such as self-locking. A functional pump system is different from a pump system that needs to be screw-locked. Because of the different functions to be realized, it is impossible to change the function of the locking cover and pressing parts. Another example is the need to realize a pump system with an external spring and a pump system with a built-in spring, which need to be realized by using different pump bodies, pump rods, and locking covers. [0003] Due to the defects in the design of the existing pump system, the components that make up the pump system cannot be made into standard com...
