Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0021] Such as Figures 1 to 3 The shown elastic integral pump core includes a pump core rod 1, a liquid guide channel 2 is arranged in the pump core rod 1, and a sealing plug 3 is integrally formed on one end of the pump core rod 1. The pump core rod 1 is integrally formed with a piston part 4, and the pump core rod 1 between the piston part 4 and the sealing plug 3 is provided with a liquid-conducting through hole 5, and the described liquid-conducting through hole 5 is connected to the The liquid guide channels 2 communicate with each other.

[0022] In the present invention, the other end of the pump core rod 1 is provided with a connecting portion 6 connected with the elbow press head, and an annular sealing ring 7 is extended on the outer wall of the connecting portion 6 .

[0023] In the present invention, the diameter of the con...

Abstract

The invention discloses an elastic integrated pump core which is characterized by comprising a pump core rod, a liquid guiding channel is arranged in the pump core rod, a sealing plug is formed on one end of the pump core integrally, a plunger piece is formed on the pump core rod integrally, a liquid guiding through hole is arranged on the pump core rod between the plunger piece and the sealing plug, and the liquid guiding through hole is communicated with the liquid guiding channel. The elastic integrated pump core aims at overcoming the defects in the prior art and is simple in structure, convenient to assemble and good in a sealing effect.

Description

technical field [0001] The invention relates to an elastic integral pump core. Background technique [0002] The traditional pump core is assembled from three parts: the pump rod, the piston and the plug, which is the core component of the pump head for sealing; but the connection between the pump rod, the piston and the plug is not enough in the existing design Strong, easy to separate during use, poor sealing effect, and inconvenient to assemble. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide an elastic integral pump core with simple structure, convenient assembly and good sealing effect. [0004] In order to achieve the above object, the present invention adopts the following scheme: [0005] An elastic integral pump core, characterized in that: it includes a pump core rod, a liquid guide channel is arranged in the pump core rod, a sealing plug is integrally formed on one end of the p...
