AI Technical Summary
When using proximity switches in the liquid tank, the detection end is located inside the liquid but the tail data line is located outside the liquid tank, which is easy to come into contact with the leaked liquid, causing the internal circuit of the data line to be disconnected, affecting the normal use of the proximity switch.
A waterproof proximity switch is designed. By setting threaded teeth on the surface of the proximity switch body, and a fixed snap and a soft rubber sleeve are set. The soft rubber sleeve comes into contact with the liquid pool during movement and stops due to the obstruction of the liquid pool. The fixed snap continues to push the soft rubber sleeve. The soft rubber sleeve completely covers the connection between the liquid pool and the proximity switch due to material characteristics to prevent liquid penetration.
Effectively prevent liquid from penetrating into the connection between the proximity switch body and the liquid pool, avoid data line failure, and ensure the normal use of the proximity switch in the liquid pool environment.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of proximity switches, in particular to a waterproof proximity switch. Background Art
[0002] Among all types of switches, there is a component that has the ability to "sense" objects approaching it - a displacement sensor. The proximity switch uses the displacement sensor's sensitive characteristics to approaching objects to control the switch on or off.
[0003] The application range of proximity switches is relatively wide. They are usually used directly under normal use conditions. However, when used in a liquid pool with the detection end located inside the liquid but the tail data line located outside the liquid pool, the tail data line part is easily in contact with the leaked liquid, causing the internal circuit of the data line to be broken, affecting the normal use of the proximity switch. Utility Model Content
[0004] The purpose of the utility model is to solve the following problems existing in the prior art:
[0005] The application range of proximity switches is relatively wide. They are usually used directly under normal use conditions. However, when used in a liquid pool with the detection end located inside the liquid but the tail data line located outside the liquid pool, the tail data line part is easily in contact with the leaked liquid, causing the internal circuit of the data line to be broken, affecting the normal use of the proximity switch.
[0006] In order to solve the problems existing in the prior art, the utility model provides a waterproof proximity switch, including a proximity switch body, the surface of the proximity switch body is provided with threaded teeth, a fixing buckle is provided on the outer side of the threaded teeth, a soft rubber sleeve is provided on the side of the fixing buckle close to the thread, and a threaded groove is provided on the inner wall of the soft rubber sleeve.
[0007] The utility model provides a waterproof proximity switch.
[0008] Furthermore, the proximity switch body includes a sensing head, a column body and a data line, wherein the surface of the column body is provided with thread teeth.
[0009] Furthermore, two fixing buckles are provided on the outer side of the threaded teeth, and soft rubber sleeves are provided on the opposite sides of the two fixing buckles.
[0010] Furthermore, the soft rubber sleeve is a cylindrical tubular structure made of rubber material, and an inclined chamfer is provided on the side away from the fixing buckle.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The utility model is installed on the inner wall of the liquid pool through the threaded teeth arranged on the surface of the proximity switch body, the sensing head is located inside the liquid pool, the data line is located inside the liquid pool, and then two fixing buckles are used to install them along the threaded teeth arranged along the sensing head and the two sides of the data line along the surface of the proximity switch column respectively. In the process of the fixing buckle moving along the threaded teeth, the soft rubber sleeve follows the movement and contacts the liquid pool during the movement. In the contact process, the end is blocked by the liquid pool and stops moving, while the rear fixing buckle continues to push the soft rubber sleeve to move until the fixing buckle can no longer move along the threaded teeth. At this time, the soft rubber sleeve is squeezed and deformed between the liquid pool and the fixing buckle, and due to its own material characteristics, it completely covers the connection between the liquid pool and the proximity switch body and continuously applies pressure there, so as to prevent the liquid in the liquid pool from gradually penetrating outwards and contacting the data line, causing partial failure of the data line.

[0020] Working principle description: The threaded teeth 2 arranged on the surface of the proximity switch body 1 are installed on the inner wall of the liquid pool, and then two fixing buckles 3 are used to be installed along the threaded teeth 2 on both sides of the proximity switch body 1. In the process of the fixing buckle 3 moving along the threaded teeth 2, the soft rubber sleeve 4 follows the movement and contacts with the liquid pool during the movement. During the contact process, the end is blocked by the liquid pool and stops moving, while the rear fixing buckle 3 continues to push the soft rubber sleeve 4 to move until the fixing buckle 3 can no longer move along the threaded teeth 2. At this time, the soft rubber sleeve 4 is squeezed and deformed between the liquid pool and the fixing buckle 3, and due to its own material properties, it completely covers the connection between the liquid pool and the proximity switch body 1 and continuously applies pressure here to ensure that no leakage occurs and the data line part of the proximity switch body 1 comes into contact with water.
