Abstract

The invention provides a connecting structure of a steel magnet and a mandrel screw rod. The connecting structure comprises a steel magnet and a mandrel screw rod, wherein the steel magnet is sleeved on the head part of the mandrel screw rod; the head part of the mandrel screw rod is provided with a reinforcement part used for reinforcing the connection with the steel magnet; and the reinforcement part is injected in the steel magnet by the steel magnet. The invention can enhance the connecting strength of the steel magnet and the mandrel screw rod so as to achieve the effect of prolonging the service life of an electronic expansion valve or a similar valve.

Description

technical field [0001] The invention relates to the field of valves, in particular to an electronic expansion valve or similar valve body in which a magnetic steel and a mandrel screw are connected. Background technique [0002] In the prior art, the rotor structure of the electronic expansion valve or similar valve body is fixedly connected by the magnetic steel and the mandrel screw. The magnetic steel is connected, so there is a hidden danger of unreliable connection, which affects the service life of the electronic expansion valve or similar valve body. Contents of the invention [0003] The invention aims to provide a connection structure between the magnet steel and the mandrel screw, which can strengthen the connection strength between the magnet steel and the mandrel screw, and can solve the existing problems such as unreliable connection between the magnet steel and the mandrel screw. [0004] In an embodiment of the invention, a connection structure between magn...
