Locking cap of standardized self-locking and screw thread-locking liquid distribution pump

Abstract

The invention discloses a locking cap of a standardized self-locking and screw thread-locking liquid distribution pump. The locking cap comprises a locking cap body in which a longitudinal through hole for containing a pump rod is formed in the locking cap body. The locking cap is characterized in that a screw thread-locking connection part which can be matched with outer connection thread on the outer wall of a pump rod connection part of an angle-jaw pressing head so as to realize screw thread locking is arranged at the upper end of the locking cap body; a self-locking connection part is arranged on the locking cap body outside the screw thread-locking connection part; and a clamping part which is used for being connected with a pump chamber is arranged on the outer wall of the locking cap body. Both the self-locking connection part and the screw thread-locking connection part are arranged on the same end. The invention aims at overcoming the deficiencies in the prior art, and providing a locking cap which is simple in structure and convenient to use and is capable of realizing a self-locking function and a screw thread-locking function at the same time.

Description

technical field [0001] The invention relates to a locking cover of a standardized self-locking and screw-locking liquid dispensing pump. Background technique [0002] At present, many products such as liquids, creams, and hairspray are dispensed by pump systems. These pump systems are generally produced using a specific design, and the accessories used are generally only assembled into one type of pump system. Existing accessories used as pump systems cannot achieve different functions. For example, if a pump system with self-locking function is formed, a self-locking locking cover needs to be matched with a specific pressing head. If a pump system with screw locking function is formed, It is necessary to use a screw locking cover to match a specific press head. There is no locking cover in the prior art that has both a self-locking locking function and a screw thread locking function. [0003] In addition, due to the defects in the design of the existing pump system, the ...

AI Technical Summary

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
