Spring-builtin standard self-locking and thread lock liquid distribution pump

Abstract

The invention discloses a spring-builtin standard self-locking and thread lock liquid distribution pump. The pump comprises a pump chamber; a pump ball mechanism is arranged in the lower part of the pump chamber; a locking bottle cap is arranged at the upper end of the pump chamber; an integral sucking plug and pump rod mechanism is arranged in the pump chamber; a locking cover device capable of preventing the integral sucking plug and pump rod mechanism from deviating from the pump chamber is arranged in the upper part of the pump chamber; the upper end of the integral sucking plug and pump rod mechanism is connected with a pump body pressing head; a positioning mechanism matched with a self-locking connecting part is arranged in the pump body pressing head; a thread matching mechanism matched with a thread locking connecting part is arranged in the pump body pressing head; and a return spring capable of returning the integral sucking plug and pump rod mechanism is arranged between the lower end of the integral sucking plug and pump rod mechanism and the inner wall of the lower part of the pump chamber. The invention aims to provide a spring-builtin emulsion pump with simple structure, capable of realizing standard production, with convenience for assembly and capable of synchronously having a self-locking function and a thread locking function.

Description

technical field [0001] The invention relates to a standardized self-locking and thread-locking liquid dispensing pump with a built-in spring. Background technique [0002] Many products such as liquids, creams and hairsprays are currently dispensed by pump systems, which are typically produced with specific designs and accessories that typically only fit together into one pump system. Existing pump system accessories cannot achieve different functions. For example, if a pump system with self-locking function is formed, a self-locking locking cover needs to be used to match a specific press head. If a pump system with thread locking function is formed, It is necessary to use a screw lock cap and a specific press head to match. In the prior art, there is no locking cover with both self-locking and locking functions and thread locking functions. [0003] In addition, due to the defects in the design of the existing pump system, the components that constitute the pump system, ...

Problems solved by technology

Existing pump system accessories cannot achieve different functions. For example, if a pump system with self-locking function is formed, a self-locking locking cover needs to be used to match a specific press head. If a pump system with thread locking function is formed, You need to use a screw lock cap and a specific press head to match

In the prior art, there is no locking cover with both self-locking locking function and thread locking function

[0003] In addition, due to the defects in the design of the existing pump system, the components that constitute the pump system, such as the locking cover, cannot be made into standard components, and it is impossible to assemble pump systems with different functions by using the same components, which will undoubtedly increase the cost of mold opening, and Need to use different assembly equipment for assembly also increases assembly cost
