[0001] The utility model relates to the technical field of pressure gauge installation, in particular to an installation structure of a pressure gauge. Background Art

[0002] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure. It is used to measure and indicate the pressure inside a pressure product. When using a pressure gauge, the user needs to install the pressure gauge, so an installation structure is required.

[0003] For example, a Chinese patent discloses: a pressure gauge installation structure, publication number: CN218628776U, "including a mounting part, a base and a pressure gauge, the top of the mounting part is in close contact with the bottom of the base, and the bottom of the pressure gauge is fixedly connected to the top of the base. The utility model, by setting the mounting part, the base, the pressure gauge, the cylinder, the fixing block, the cavity, the positioning device and the pulling device for coordinated use, the positioning device can be used in coordination with the inside of the cylinder through the fixing block, so that the fixing block can be fixed to the cylinder, and the base drives the pressure gauge to be fixed to the mounting part. The pulling device and the positioning device are used in coordination, and the base drives the pressure gauge to be separated from the mounting part, which has the advantage of being easy for users to disassemble and assemble the pressure gauge. This pressure gauge installation structure solves the problem that the existing installation process of the pressure gauge is not fast enough and is relatively troublesome, and different threads require different mounting parts to be used in coordination to achieve disassembly and assembly." However, in the process of installing the pressure gauge in the pipeline, there are problems of inconvenience in installation and disassembly, and the operation is relatively inconvenient.

The sliding of the two clamping blocks 7 will drive the limiting rod 71 to slide, and the sliding of the limiting rod 71 will apply a force to the arc spring 72, so that the two arc springs 72 are compressed. Then, the two clamping blocks 7 are respectively aligned with the insertion opening 41 and inserted therein, and the two clamping blocks 7 are released. The elastic reset effect of the arc spring 72 is used to make the two clamping blocks 7 respectively engage in the clamping groove 42, so that the fixing plate 6 and the fixing ring 4 are engaged and fixed. At this time, the mounting tube 2 is connected and communicated with the connecting tube 11, and the installation and fixation of the pressure gauge body 1 is completed. When the pressure gauge body 1 is disassembled, the staff pushes the two clamping blocks 7 and moves the pressure gauge body 1 upwards to separate it from the mounting tube 2, which is relatively simple for the installation and disassembly of the pressure gauge body 1.

[0025] Working principle:

[0026] The first step is to install the pressure gauge body 1 by inserting the installation sleeve 3 at the connecting pipe 11 into the installation groove 31 and pushing the two clamping blocks 7 so that the two clamping blocks 7 slide to fit the inner wall of the notch 61 respectively. The sliding of the two clamping blocks 7 will drive the limit rod 71 to slide, and the sliding of the limit rod 71 will apply a force to the arc spring 72 so that the arc spring 72 is compressed. Then, the two clamping blocks 7 are respectively aligned with the insertion opening 41 and inserted therein, and the two clamping blocks 7 are released. The elastic reset effect of the arc spring 72 is used to make the two clamping blocks 7 respectively engage in the clamping groove 42, so that the fixing plate 6 and the fixing ring 4 are engaged and fixed. At this time, the installation pipe 2 is connected to the connecting pipe 11, and the installation and fixation of the pressure gauge body 1 are completed. When the pressure gauge body 1 is disassembled, the staff pushes the two clamping blocks 7 and moves the pressure gauge body 1 upward to separate it from the installation pipe 2, which is relatively simple for the installation and disassembly of the pressure gauge body 1.

[0027] In the second step, the limiting rods 71 ​​are fixedly installed on the card blocks 7, and each limiting rod 71 is slidably installed inside the fixed plate 6, which limits the sliding trajectory of the card blocks 7, ensuring that the two card blocks 7 can be smoothly inserted from the insertion port 41 and clamped in the card groove 42, thereby ensuring the rationality of the structural design. A sealing gasket is provided between the fixed plate 6 and the fixed ring 4, which seals the connection between the connecting pipe 11 and the mounting pipe 2.
