Standardized self-locking and screw-locking liquid distribution pump with external spring

Abstract

The invention discloses a standardized self-locking and screw-tooth locking liquid distribution pump with an external spring, which includes a pump chamber, a pump bead mechanism capable of closing the liquid inlet at the lower end of the pump chamber is arranged in the lower part of the pump chamber, and a pump ball mechanism is arranged at the upper end of the pump chamber. The bottle lock cap is equipped with an integrated suction plug pump rod mechanism in the pump chamber, and a locking cap device that can prevent the integrated suction plug pump rod mechanism from detaching from the pump chamber is installed in the upper part of the pump chamber. The upper end is connected with the pump body press head, and a positioning mechanism that cooperates with the self-locking connection part is provided in the pump body press head, and a thread matching mechanism that cooperates with the thread locking connection part is provided in the pump body press head. A back-moving spring is sheathed on the outside of the tooth-locking connection, the upper end of the back-moving spring presses against the press head of the pump body, and the lower end of the back-moving spring presses against the locking cover body. The invention provides a spring-mounted lotion pump with simple structure, which can realize standardized production, is convenient to assemble, and can simultaneously have the functions of self-locking and thread locking.

Description

technical field [0001] The invention relates to a standardized self-locking and thread-locking liquid dispensing pump with external springs. 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, s...

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
