Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a sensor sealing structure that is easy to assemble. Background Technology

[0002] With economic development, sensors are being used more and more widely in various situations. A sensor is a detection device that can sense the information being measured and transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] Currently, in traditional solutions, the sensor sealing assembly methods are basically 1. threaded assembly with sealing gaskets and thread sealant; 2. bolt hole installation with sealing ring assembly.

[0004] The use of threaded assembly with sealing gaskets and thread sealant requires the sensor to have a threaded structure, necessitating a metal housing that cannot be made of soft metals like aluminum. This results in extremely high material and processing costs. Furthermore, since the final mating surface of the sensor cannot be threaded, bolts, gaskets, and sealant are needed to reinforce the seal if the threaded sealing effect is not ideal. Therefore, threaded sensor structures suffer from drawbacks such as large installation volume, high cost, and complex product assembly.

[0005] The most common assembly method for sensors is bolt hole mounting and sealing ring assembly. The sealing area of ​​the product must not have machining marks or die-casting pores over a considerable area. Similarly, the sensor sealing area must be free of burrs, burn marks, or other defects. Furthermore, bolt installation is required after product assembly, necessitating a separate bolt installation station. Both of these installation methods have significant drawbacks, requiring threaded assembly. Assembling multiple sensors on the same housing greatly increases labor time and demands high precision in the assembly structure, thus necessitating improvement. Utility Model Content

[0006] This utility model provides a sensor sealing structure that is easy to assemble, utilizes any pipeline or client-related assembly structure design, can effectively ensure assembly sealing and efficient assembly, and can meet higher practical requirements. It solves the technical problems of existing sensors, such as the relatively simple assembly structure, high requirements for assembly structure accuracy, long assembly time and high cost, and inability to use bolt guns or other tools for installation in some small spaces, thus failing to meet higher usage requirements.

[0007] The above-mentioned technical problem of this utility model is solved by the following technical solution: a sensor sealing structure that is easy to assemble, including a housing, wherein a mounting hole is pre-drilled on the housing, a sensor is embedded in the mounting hole, a sealing ring that mates with the housing is sleeved on the mounting end of the sensor, and a limiting member for fixing the sensor is provided on the housing. In this utility model, the housing is the client for sensor installation, such as a pipe or gearbox, with a mounting hole pre-drilled on the client housing; during installation, the sealing ring is pre-installed on the bottom end of the sensor, and the sealing ring mates with the housing to achieve a seal, while also increasing friction to ensure a limiting effect. Furthermore, the sealing ring assists in installation, ensuring the coaxiality of the sensor and the mounting hole; during installation, the sensor is inserted into the mounting hole, and then the limiting member limits and fixes the sensor.

[0008] Preferably, the limiting component includes a slot formed on the housing, and a detachable irregularly shaped retaining spring is provided in the slot. The housing in this invention serves as the client for sensor installation, such as a pipe or gearbox. Mounting holes and slots are pre-formed on the client housing, and the sensor is limited by the irregularly shaped retaining spring and its own structure. This allows for quick and convenient installation, reduces the assembly space requirements of the sensor, and improves installation efficiency and reliability during production.

[0009] Preferably, the slots are C-shaped slots formed on both sides of the housing. Two C-shaped slots are formed on both sides of the top of the housing for mating and engaging with irregularly shaped retaining springs.

[0010] Preferably, the irregularly shaped retaining ring is a C-shaped structure with one side open, and the two sides of the retaining ring tighten towards the center for secure locking. During installation, the sensor is inserted into the mounting hole, and then the irregularly shaped retaining ring is secured in the slots on both sides. The retaining ring and the sensor's own structure achieve positioning, making installation quick and convenient, reducing the assembly space requirements of the sensor, and improving installation efficiency and reliability in the production process.

[0011] Preferably, the irregularly shaped retaining ring is attached to the smaller diameter section of the sensor. Since the dimensions of different parts of the sensor's structure vary, the irregularly shaped retaining ring, in conjunction with the sensor's structure, can achieve a limiting effect. The irregularly shaped retaining ring is attached to the smaller diameter middle section of the sensor, and secured by the larger upper and lower structures, preventing the sensor from loosening or falling off.

[0012] Therefore, the sensor sealing structure of this utility model that is easy to assemble has the following advantages: it is easy to assemble, and by utilizing any pipeline or client-related assembly structure design, it can well ensure assembly sealing and efficient assembly, and can meet higher practical requirements.

[0020] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] Example:

[0022] like Figure 1 and 2 As shown in Figures 3, 4, 5, and 6, a sensor sealing structure that is easy to assemble includes a housing 1, a mounting hole 2 pre-drilled on the housing 1, a sensor 6 installed in the mounting hole 2, a sealing ring 3 fitted to the bottom of the sensor 6 and cooperating with the housing 1, and a limiting member for fixing the sensor 6 installed on the housing 1.

[0023] The limiting component includes a slot 4 on the top of the housing 1, which is two C-shaped slots on both sides of the housing 1. A detachable irregularly shaped retaining spring 5 is installed in the slot 4.

[0024] The irregularly shaped retaining ring 5 is attached to the smaller diameter section of the sensor 6, while the sensor 6 has a larger diameter at the bottom of the irregularly shaped retaining ring 5.

[0025] The irregularly shaped retaining ring 5 has a C-shaped structure that is open on one side, and the two sides of the irregularly shaped retaining ring 5 are tightened towards the center to secure it.

[0026] In this utility model, the housing 1 is the client on which the sensor 6 is installed, such as a pipe or gearbox. Mounting holes 2 and slots 4 are pre-made on the client housing 1.

[0027] During installation, the sealing ring 3 is pre-installed at the bottom of the sensor 6. The sealing ring 3 cooperates with the housing 1 to achieve a seal, while also increasing friction to ensure the limiting effect. In addition, the sealing ring 3 can assist in the installation to ensure the coaxiality of the sensor 6 and the mounting hole 2.

[0028] During installation, the sensor 6 is inserted into the mounting hole 2, and then the irregularly shaped retaining ring 5 is clipped into the slots 4 on both sides. The retaining ring 5 and the sensor 6 itself achieve positioning, making installation quick and convenient. This reduces the assembly space requirement of the sensor 6, improves the installation efficiency and reliability in the production process, and the sealing structure of this utility model, together with the sealing ring 3, can improve the vibration resistance and prevent the sensor 6 from falling off or loosening.
