Description

Technical Field

[0001] The utility model relates to sensor-related fields, in particular to a pressure sensor that is easy to install. Background Art

[0002] Pressure sensor is a device or apparatus that can sense pressure signal and convert pressure signal into usable output electrical signal according to certain rules. Pressure sensor is usually composed of pressure sensitive element and signal processing unit. According to different test pressure types, pressure sensor can be divided into gauge pressure sensor, differential pressure sensor and absolute pressure sensor. Pressure sensor is the most commonly used sensor in industry. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent building, production automatic control, aerospace, military industry, petrochemical, oil well, electric power, shipbuilding, machine tools, pipelines and many other industries.

[0003] Existing pressure sensors usually use multiple bolts and flanges to achieve installation on the pipeline, or use direct threaded installation. The flange installation and disassembly requires the use of external tools for assembly and disassembly, and the disassembly and assembly process is relatively cumbersome. If the threaded installation is directly used, after the pressure sensor is installed and fixed in place, it is difficult to ensure the direction of the wire plug at the end of the sensor, which affects the subsequent connection work, thereby reducing the convenience of installing and adjusting the pressure sensor. Therefore, a mounting structure of a pressure sensor is proposed to solve the above problem. Utility Model Content

The pressure sensor body is composed of a sensor housing 5 and a sensor probe 6 at the bottom. The upper end of the connection seat 2 is penetrated with an insertion port 3 connected to the inner cavity, and the pressure sensor body movably penetrates the insertion port 3 and extends to the inner cavity of the pipeline 1. The outer side of the sensor housing 5 is fixedly sleeved with a sealing seat 7 that is docked at the upper end of the connection seat 2. Brackets 8 are fixedly connected to both sides of the sealing seat 7. The brackets 8 on both sides are horizontally movably penetrated with limit pins 9 and threaded pins 10, and both sides of the connection seat 2 are provided with The limiting hole 4 is docked with the limiting pin 9 and the threaded pin 10, and the outer end of the limiting pin 9 is fixedly connected with a fixing block 901, and the fixing block 901 is connected to the outer side of the one side bracket 8 through a contracted spring 902, and the outer side of the other side bracket 8 is transversely penetrated with a plug-in hole 1001, and the threaded pin 10 is movably penetrated and connected to the plug-in hole 1001, and the outer side of the plug-in hole 1001 is rotatably connected with an adjustment sleeve 1002 threadedly sleeved on the outer side of the threaded pin 10, a limiting groove 1003 is transversely arranged on the outer side of the threaded pin 10, and the inner wall of the plug-in hole 1001 is fixedly connected with a limiting block that is snap-fitted with the limiting groove 1003.

[0023] Based on the above structure, when the device is in use, the staff pre-connects the sealing seat 7 to the top of the connecting seat 2 at the upper end of the pipe 1, then pulls the fixing block 901 and stretches the spring 902, so that the limit pin 9 moves outward and presses down the pressure sensor body. At this time, the sensor probe 6 and the sensor housing 5 at the bottom of the pressure sensor body move through the plug interface 3 above the connecting seat 2 in turn until the sealing seat 7 is connected to the upper end of the connecting seat 2, and then releases the fixing block 9 to drive the limit pin 9 to be clamped in the limit hole 4 on one side of the connecting seat 2 under the elastic restoring force of the spring 902, and then rotates the adjusting sleeve 1002, and the adjusting sleeve 1002 threadably drives the threaded pin 10. Since the limit groove 1003 on the outer side of the threaded pin 10 is clamped with the limit block on the inner wall of the plug hole 1001, the threaded pin 10 moves horizontally and is clamped in the limit hole 4 on the other side of the connecting seat 2, thereby completing the reinforcement of the connection of the sealing seat 7, that is, the portable and stable installation of the pressure sensor body, without the assistance of tools, and is very easy to use.
