Description

Technical Field

[0001] This utility model relates to the field of displacement sensor technology, specifically a waterproof linear displacement sensor with an elastic corrugated sleeve. Background Technology

[0002] Currently, corrugated pipes need to be installed on sensor cables. Generally, corrugated pipes come with standard corrugated pipe connectors. The standard corrugated pipe connectors are relatively large, which is not suitable for connecting small external sensors. External parts must be small to fit in, and they cannot have any additional impact on sensor performance. Furthermore, there is no waterproof or dustproof effect between the corrugated pipe connector and the corrugated pipe, which is very inconvenient during use.

[0003] To address the aforementioned issues, there is an urgent need to design a waterproof linear displacement sensor with an elastic corrugated sleeve. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof linear displacement sensor with an elastic corrugated sleeve, in order to solve the problems mentioned in the background art, such as the standard corrugated pipe joint being too large, unsuitable for connecting small sensors, requiring small external parts to be installed without affecting sensor performance, and the lack of waterproof and dustproof protection between the corrugated pipe joint and the corrugated pipe, which is very inconvenient during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof linear displacement sensor with an elastic corrugated sleeve, comprising a sensor body, a connector installed at one end of the sensor body, an elastic corrugated sleeve provided on the outer side of the sensor body, rings installed at both ends of the elastic corrugated sleeve, a mating ring fixed on the ring, a tightening ring provided on the outer side of the mating ring, a mating groove provided on the tightening ring, and the mating ring located in the mating groove.

[0006] Preferably, the mating head has a tightening groove, and a sealing gasket is provided at the bottom of the tightening groove.

[0007] Preferably, the elastic corrugated sleeve and the ring body are connected by heat fusion.

[0008] Preferably, the ring body is rotatably connected to the tightening ring via a mating ring and a mating groove.

[0009] Preferably, a sealing ring is provided between the inner wall of the docking ring and the docking groove.

[0010] Preferably, the tightening ring is located in the tightening groove, the tightening ring is threadedly connected to the connector through the tightening groove, and one end of the tightening ring is pressed against the surface of the sealing gasket.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when the tightening ring is turned, the tightening ring will rotate on the ring body through the mating ring and the mating groove, so that the rotating tightening ring can be screwed into the tightening groove on the mating joint, which facilitates the connection between the tightening ring and the mating joint. Thus, the elastic corrugated sleeve is connected to the sensor body. A sealing ring is provided at the connection between the ring body and the tightening ring, and a sealing gasket is provided between the tightening ring and the mating joint, which can improve the sealing performance and achieve dustproof and waterproof.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a waterproof linear displacement sensor with an elastic corrugated sleeve, including a sensor body 1, a connector 2 installed at one end of the sensor body 1, an elastic corrugated sleeve 5 provided on the outer side of the sensor body 1, a ring body 6 installed at both ends of the elastic corrugated sleeve 5, a docking ring 7 fixed on the ring body 6, a tightening ring 8 provided on the outer side of the docking ring 7, a docking groove 9 opened on the tightening ring 8, and the docking ring 7 located in the docking groove 9.

[0019] The connector 2 has a tightening groove 3, and a sealing gasket 4 is provided at the bottom of the tightening groove 3, which facilitates the stable connection of subsequent related components to the connector 2 through the tightening groove 3. The sealing gasket 4 can improve the structural sealing performance.

[0020] The elastic corrugated sleeve 5 and the ring body 6 are connected by heat fusion, which improves the stability of the connection between the elastic corrugated sleeve 5 and the ring body 6 and prevents loosening.

[0021] The ring body 6 is rotatably connected to the tightening ring 8 via the docking ring 7 and the docking groove 9, which facilitates the rotation of the tightening ring 8 on the ring body 6 via the docking ring 7 and the docking groove 9.

[0022] A sealing ring 10 is provided between the inner walls of the docking ring 7 and the docking groove 9, which improves the sealing performance between the docking ring 7 and the docking groove 9 and prevents water leakage.

[0023] The tightening ring 8 is located in the tightening groove 3. The tightening ring 8 is threadedly connected to the connector 2 through the tightening groove 3. One end of the tightening ring 8 is pressed tightly against the surface of the sealing gasket 4, which improves the stability of the connection between the tightening ring 8 and the connector 2. The setting of the sealing gasket 4 improves the sealing performance between the tightening ring 8 and the connector 2.

[0024] Working principle: According to Figures 1-4 As shown, firstly, the elastic corrugated sleeve 5, along with the ring body 6 and the tightening ring 8, is placed over the wires of the sensor body 1. Then, the tightening ring 8 is aligned with the tightening groove 3 on the connector 2, and the tightening ring 8 is tightened. The tightening ring 8 will rotate on the ring body 6 through the connecting ring 7 and the connecting groove 9, so that the rotating tightening ring 8 can be screwed into the tightening groove 3 on the connector 2, which facilitates the connection between the tightening ring 8 and the connector 2. Thus, the elastic corrugated sleeve 5 and the sensor body 1 are connected. A sealing ring 10 is provided at the connection between the ring body 6 and the tightening ring 8, and a sealing gasket 4 is provided between the tightening ring 8 and the connector 2, which can improve the sealing performance and achieve dustproof and waterproof.
