Abstract

The invention relates to an external elastomer plastic cement spring pressing pump which comprises a pressing head, screw teeth, a lock cover, a spring, a body, a main column, an auxiliary column and a piston. The pressing head further comprises a locking sleeve, and a locking buckle is arranged at the lower end of the interior of the locking sleeve; the spring is made of a elastomer plastic cement material; a liquid outlet hole is formed in the upper end of the main column; openings are formed in the two ends of the auxiliary column, the auxiliary column is hollow, and a cone-frustum-shaped upper valve element base is arranged at the lower end of the auxiliary column; the piston is arranged at the lower end of the auxiliary column and is integrally molded; a valve element assembly is further included and comprises an upper valve element, a connecting rod, a support, a ring base, a round valve element and an arc elastic connecting piece, in the working process, the locking buckle and the locking position are separated, and the liquid outlet hole of the main column is opposite to the liquid inlet end of the liquid outlet pipe; and in the storing process, the locking buckle and the locking position are locked, the liquid inlet end of the liquid outlet pipe is sealed through the upper end of the main column. As the structure is adopted, the spring is made of a rubber material, and assembly is convenient; and the pressing head and the lock cover are locked, and liquid leakage caused during pouring can be prevented.

Description

technical field [0001] The invention relates to a spray pump. Background technique [0002] In the current prior art, a spray pump includes a press head, screw teeth, a lock cover, a spring, a body, a main post, an auxiliary post, a piston and a steel ball, and the press head includes a body with a lower opening and an outlet connected to the body. liquid pipe. The existing problems are: the spring is made of metal material, which is easy to rust, and the assembly needs to be preloaded, so the work efficiency is low; when it is poured, it will leak. Contents of the invention [0003] The object of the present invention is to provide an external elastic body plastic spring pressing pump, which not only has the characteristics of high work efficiency, but also has the characteristics of dumping and preventing leakage. [0004] The present invention is achieved in this way: an external elastic body plastic spring press pump, including a press head, a thread, a lock cover, a...
