Description

Technical Field

[0001] The present invention relates to the field of sensors, and more particularly to a protective device for a water temperature sensor joint. Background Art

[0002] During the use of the water temperature sensor, the threaded head at the end is usually connected to the inside of the installation hole, and then the detection rod is inserted into the water to detect the water temperature. In order to ensure the safety and stability of the sensor installation and use, the sensor needs to be protected.

[0003] However, existing sensor protection devices mostly use external covers for connection and positioning, which not only greatly increases the installation volume and is prone to interference and misalignment, but also requires drilling holes in the box for alignment installation, which is not conducive to operation. Directly inserting the sleeve for protection is prone to misoperation and causing the sensor to loosen and leak, and has poor stability, which needs to be improved. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a protective device for the water temperature sensor connector, which connects the hexagonal head and the threaded rod through the sensor body. A wrench can be used to tighten the threads, which is convenient for installation. It is sealed in combination with the sealing ring on the side to avoid leakage at the connection position, which is safe and stable. At the same time, by rotating the sleeve protective tube, isolation protection can be performed while avoiding loosening due to misoperation. This can greatly improve the convenience and stability of use and ensure the safety of protection.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A protective device for a water temperature sensor joint comprises a sensor body, one end surface of the sensor body is fixedly connected to a hexagonal head, one side surface of the hexagonal head is fixedly connected to a threaded rod, one end surface of the threaded rod is fixedly installed with a detection rod, one side surface of the hexagonal head is provided with an annular groove, a sealing ring is fixedly installed on the side of the annular groove, the side of the sealing ring is sleeved on one end position of the threaded rod, the other end surface of the sensor body is rotatably sleeved with a protective tube, one end side surface of the protective tube is slidably sleeved on the surface of the hexagonal head, one end side surface of the protective tube is fixedly connected with an annular magnet, the other end surface of the protective tube is fixedly connected with a guide ring, the side surface of the guide ring is slidably sleeved on one end surface of the sensor body, and one end side surface of the protective tube is provided with a limiting socket.

[0007] Furthermore, the other end surface of the sensor body is fixedly connected to a limit plate. By installing the limit plate, the protective tube can be prevented from falling out, thereby improving the stability of the connection.

[0008] Furthermore, tensioning springs are fixedly connected to the side surfaces of both ends of the limiting plate.

[0009] Further, the surfaces of the pressing springs are located on both sides of the sensor body. By installing the pressing springs, pressing and positioning can be achieved, which is beneficial to stable connection.

[0010] Further, a connecting ring is fixedly connected to the surface of the pressing spring.

[0011] Further, the side surface of the connecting ring is slidably sleeved on the surface of the sensor body. By installing the connecting ring, the rotation of the protective cylinder will not be interfered, and at the same time, it is beneficial to pressing and limiting to avoid loosening.

[0012] Further, a pressing head is fixedly connected to the side surface of the connecting ring.

[0013] Further, the surface of the pressing head is tightly connected to the side surface of the guiding ring. By connecting the guiding ring with the pressing head, support and pressing can be achieved, and at the same time, the contact surface is reduced to avoid interfering with rotation and facilitate adjustment and use.

[0014] Compared with the prior art, the advantages of the present invention are as follows:

[0015] (1) In this solution, the sensor body is connected to the hexagonal head and the threaded rod, and a wrench can be used for thread tightening, which is convenient for installation. Sealing is carried out by combining the sealing ring on the side to avoid leakage at the connection position, ensuring safety and stability. At the same time, by rotatably sleeving the protective cylinder, isolation and protection can be achieved while preventing loosening due to misoperation.

[0016] (2) By installing the limiting plate, the protective cylinder can be prevented from coming off, improving the stability of the connection.

[0017] (3) By installing the pressing springs, pressing and positioning can be achieved, which is beneficial to stable connection.

[0018] (4) By installing the connecting ring, the rotation of the protective cylinder will not be interfered, and at the same time, it is beneficial to pressing and limiting to avoid loosening.

[0019] (5) By connecting the guiding ring with the pressing head, support and pressing can be achieved, and at the same time, the contact surface is reduced to avoid interfering with rotation and facilitate adjustment and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-3 , a protection device for a water temperature sensor connector, including a sensor body 1, please refer to Figure 1 and Figure 2 , one end surface of the sensor body 1 is fixedly connected with a hexagon head 11, one side surface of the hexagon head 11 is fixedly connected with a threaded rod 12, which can be installed and fixed by threading with a wrench, facilitating alignment installation and use. One end surface of the threaded rod 12 is fixedly installed with a detection rod 13, which can be inserted into the water tank to detect the water temperature, and will not be elaborated here. One side surface of the hexagon head 11 is provided with an annular groove 14, and a sealing ring 15 is fixedly installed on the side surface of the annular groove 14, which can press against the installation plane for sealing to avoid leakage, ensuring safety and stability. The side surface of the sealing ring 15 is sleeved on one end position of the threaded rod 12. The other end surface of the sensor body 1 is rotatably sleeved with a protection cylinder 16, which can protect the internal structure and can rotate around the surface of the sensor body 1. In this way, when there is a misoperation, it will not drive the sensor body 1 to rotate, thereby avoiding loosening and leakage and ensuring the safety protection effect. One end side surface of the protection cylinder 16 is slidably sleeved on the surface of the hexagon head 11. One end side surface of the protection cylinder 16 is fixedly connected with an annular magnet 17. The other end surface of the protection cylinder 16 is fixedly connected with a guide ring 18. The side surface of the guide ring 18 is slidably sleeved on one end surface of the sensor body 1. One end side surface of the protection cylinder 16 is provided with a limit jack 24, which can insert a plug rod to limit the protection cylinder 16 to avoid interference during installation and facilitate adjustment and use.

[0027] Please refer to Figure 1 and Figure 2, on the other end surface of the sensor body 1, a limiting plate 2 is fixedly connected. The surface of the limiting plate 2 is supported and connected to the other end side surface of the protective cylinder 16. By installing the limiting plate 2, the protective cylinder can be prevented from coming off, improving the stability of the connection. On the two end side surfaces of the limiting plate 2, tightening springs 21 are fixedly connected. The surfaces of the tightening springs 21 are located on both sides of the sensor body 1. By installing the tightening springs 21, they can be tightened and positioned, facilitating stable connection. On the surface of the tightening spring 21, a connecting ring 22 is fixedly connected. The side surface of the connecting ring 22 is slidably sleeved on the surface of the sensor body 1. By installing the connecting ring 22, it will not interfere with the rotation of the protective cylinder, and at the same time is conducive to tightening and limiting to avoid loosening. On the side surface of the connecting ring 22, a tightening head 23 is fixedly connected. The surface of the tightening head 23 is tightly connected to the side surface of the guiding ring 18. By connecting the guiding ring 18 with the tightening head 23, it can be supported and tightened, and at the same time the contact surface is reduced to avoid interfering with rotation and facilitating adjustment and use.

[0028] During use, the protective cylinder 16 can be pulled forward. After contraction, it disengages from the hexagonal head 11 to avoid interference. Then, the limiting jack 24 is moved to the front side position of the limiting plate 2, and a nail is inserted to limit the position to avoid interference caused by contraction and reset. Then, a wrench can be used to connect to the hexagonal head 11 and be installed into the installation hole through the threaded rod 12, which is conducive to tightening and fixing. Combined with the sealing ring 15, it tightens the installation plane for sealing to avoid leakage, ensuring safety and stability. Then, the nail is pulled out, and the tightening spring 21 pushes the connecting ring 22 to move. The guiding ring 18 is pushed by the tightening head 23 to push the protective cylinder 16 to reset, which can completely cover the sensor body 1 and the hexagonal head 11 for isolation and protection. At the same time, the annular magnet 17 is adsorbed onto the installation plane for positioning, which is relatively stable, and thus the internal structure can be protected. At the same time, it can rotate around the surface of the sensor body 1, so that the sensor body 1 will not rotate when there is a misoperation, thereby avoiding loosening and leakage and ensuring the safety protection effect.

[0029] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitution or change, and should be covered by the protection scope of the present invention.
