Description

Technical Field

[0001] The present application relates to the field of solenoid valves, and in particular to a cover pressing mechanism for a spring pin press-fitting tool. Background Art

[0002] In the prior art, the solenoid valve core and the solenoid valve core sealing head are assembled by spring pins. The manual assembly process is cumbersome and it is impossible to ensure that the spring pin is coaxial with the pin holes on the solenoid valve core and the sealing head, which leads to assembly defects or damage to various components.

[0003] The invention with patent number CN215318446U discloses a spring pin pressing tool, which uses a lifting rod to coaxially limit the assembly holes of the solenoid valve core and the sealing head, and then presses the spring pin in through the guide hole. It has a good limiting effect, avoids manual positioning by observation, and has a better assembly effect. The pressing process is always coaxial, avoiding damage to parts and improving the pressing efficiency.

[0004] However, during the assembly process, after one of the spring pins is pressed in, the reaction force of the spring will cause the pressing block to tilt up, affecting the assembly of the remaining spring pins. Summary of the invention

The first arc groove 307 and the second arc groove 308 on the inner wall on the same side of the cavity 304 are symmetrically arranged up and down, and the first arc groove 307 gradually bends downward toward the side away from the pressure block 2, and the end face of the vertical block 302 away from the pressure block 2 is connected to the inner wall of the cavity 304 through the elastic member 4, and a locking tongue 5 is convexly provided on the end face of the vertical block 302 facing the pressure block 2, and a locking block 6 cooperating with the locking tongue 5 is provided on the end face of the pressure block 2 facing the vertical block 302, and a notch 7 connected to the cavity 304 is provided on the pressure block 2, and the handle 303 is fixedly connected to the top of the vertical block 302 through the notch 7.

[0019] Furthermore, the cross section of the locking tongue 5 is a right triangle.

[0020] Furthermore, the elastic member 4 is a spring.

[0021] Furthermore, the handle 303 can swing in the notch 7 .

[0022] Furthermore, the locking tongue 5 and the vertical block 302 are integrally formed, and the locking block 6 and the pressing block 2 are integrally formed.

[0023] In this technical solution, the cover pressing mechanism realizes the rapid disassembly and connection between the pressing block and the base through structural coordination, ensuring that the pressing block does not warp during the assembly process, facilitating assembly and improving assembly efficiency.

[0024] Specific implementation principle:

[0025] When the briquette 2 presses down onto the base 1, the locking block 6 moves downward along the curvature of the locking tongue 5 and exerts a lateral force on the locking tongue 5. At this time, the vertical block 302 is stressed. Hold the handle 303 and make the vertical block 302 flip along the second arc groove 308 with the first connecting shaft 305 as the center. When the locking tongue 5 moves below the locking block 6, release the handle 303. The reaction force of the spring on the vertical block 302 causes the vertical block 302 to return to its original position, and the locking tongue 5 and the locking block 6 are locked. During disassembly, press the handle 303 to make the vertical block 302 flip along the first arc groove 307 with the second connecting shaft 306 as the center. The vertical block 302 drives the locking tongue 5 away from the locking block 6, so that the briquette 2 can be removed from the base 1 to achieve disassembly.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense.
