Standardized thread lock liquid dispensing pump with external spring

Abstract

The invention discloses a standardized screw-tooth lock liquid dispensing pump with an external spring, which includes a pump chamber, a pump bead mechanism is arranged in the lower part of the pump chamber, a bottle lock cap is arranged at the upper end of the pump chamber, and a bottle lock cap is arranged on the pump chamber. There is an integrated suction plug pump rod mechanism in the room, and a screw thread locking cover is provided in the upper part of the pump chamber. A pump body press head is connected to the upper end of the integrated suction plug pump rod mechanism. The press head is provided with an external thread that cooperates with the internal thread, and a return spring is provided on the outer cover of the screw connection part. The upper end of the return spring presses against the pump body press head, and the lower end of the return spring presses against the locking Cover the body. The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a standard integrated liquid distribution pump system with simple structure, which can realize standardized production, convenient assembly, and can select and replace different standardized components according to functional requirements.

Description

technical field [0001] The invention relates to a standardized thread lock liquid dispensing pump with external springs. Background technique [0002] At present, many products such as liquids, face creams, and hair styling gels are distributed by pump systems. These pump systems are generally produced with specific designs, and pump systems with different functions cannot be assembled by changing accessories, such as self-locking. The functional pump system and the pump system that needs to realize screw locking, because of the different functions to be realized, it is impossible to realize the functional transformation by changing the locking cover and the pressing head parts. Another example is 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, locking covers, etc. [0003] Due to the defects in the design of the existing pump system, the components that make up t...

AI Technical Summary

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
