[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] In the description of the utility model, it is understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated components or elements must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the utility model.

[0029] Please refer to Figures 1-6 The utility model discloses a portable pressure gauge installation mechanism, including pressure gauge body 1, one end of pressure gauge body 1 is equipped with installation assembly 3, one end of installation assembly 3 is equipped with pipeline 4 with thread, the inner chamber of pipeline 4 and installation assembly 3 are equipped with sealing assembly 5, two sealing assembly 5 are sealed between pipeline 4 and installation assembly 3 respectively, two sealing assembly 5 are close to contact each other and are pushed mutually, to make pipeline 4 and installation assembly 3 communicate, two sealing assembly 5 are far away from each other, and pipeline 4 and installation assembly 3 are sealed respectively.

[0030] The pressure gauge body 1 is provided with a mounting assembly 3 at one end, and a pipeline 4 is screwed to one end of the mounting assembly 3. During the mounting process, when the mounting assembly 3 is screwed to the pipeline 4, the sealing assemblies 5 provided in the inner cavities of the pipeline 4 and the mounting assembly 3 will be in close contact with each other. As the mounting assembly 3 is continuously screwed in, the two sealing assemblies 5 will push each other. This pushing changes the original sealing state, thereby enabling the pipeline 4 to communicate with the mounting assembly 3, realizing pressure transmission and other functions, and enabling the pressure gauge to accurately measure the pressure in the pipeline 4.

[0031] When the pressure gauge body 1 needs to be disassembled for maintenance or the like, the two sealing assemblies 5 will move away from each other. At this time, due to the internal elastic properties of each sealing assembly 5, the sealing assembly 5 will respectively seal the pipeline 4 and the mounting assembly 3, preventing harmful gases in the pipeline 4 from leaking out of the pipeline 4, effectively preventing harmful gases from being emitted to the outside environment, and protecting the safety of the on-site operators and the surrounding environment from pollution.

[0032] Thus, when the pressure gauge body 1 is disassembled for maintenance, the two sealing assemblies 5 move away from each other, and by virtue of their internal elasticity, they respectively seal the inner cavities of the pipeline 4 and the mounting assembly 3, preventing harmful gases in the pipeline 4 from leaking, and protecting personnel safety and the environment from pollution.

[0033] In one embodiment, for the above-mentioned mounting assembly 3, the mounting assembly 3 comprises a mounting pipe 301, the mounting pipe 301 communicates with the pressure gauge body 1, a fixed plate 302 is fixedly installed on the circumferential surface of the mounting pipe 301, a threaded cap 303 is rotatably installed at one end of the fixed plate 302, and the threaded cap 303 is screwed to the pipeline 4.

[0034] The mounting pipe 301 serves as a bridge for connecting the pressure gauge body 1 and the pipeline 4, and plays a role in pressure transmission, ensuring that the pressure in the mounting pipe 301 can be accurately transmitted to the pressure gauge body 1 for measurement and display. When performing the mounting operation, first, one end of the mounting pipe 301 is aligned with the pipeline 4, so that the two are initially connected. At this time, the threaded cap 303 rotatably installed at one end of the fixed plate 302 is rotated. Since the threaded cap 303 is screwed to the pipeline 4, as the threaded cap 303 is rotated, it will gradually screw into and tighten the pipeline 4. In this process, the threaded cap 303 will exert an inward axial force on the mounting pipe 301, making the connection between the mounting pipe 301 and the pipeline 4 more and more tight, forming a reliable sealing connection. This sealing connection can effectively prevent the gas in the pipeline from leaking outwards during the pressure gauge mounting process. Even if there are harmful gases in the pipeline 4, they can also be safely enclosed in the pipeline 4.

[0035] When disassembling the pressure gauge, the threaded cap 303 is rotated in the opposite direction, so that it gradually loosens the connection with the pipeline 4, thereby enabling the mounting pipe 301 to be separated from the pipeline 4.

[0036] In one embodiment, for the installation pipe 301 described above, the installation pipe 301 and the inner cavity of the pipe 4 are both fixedly installed with resisting plates 304, and the two resisting plates 304 are symmetrically arranged.

[0037] The sealing assembly 5 comprises support rods 501, two of which are fixedly installed in the installation pipe 301 and the inner cavity of the pipe 4 respectively, and the inside of the support rod 501 is slidably installed with a sliding rod 502.

[0038] The sliding rod 502 is sleeved with a spring 503 on the circumferential surface thereof, and one end of the sliding rod 502 is fixedly installed with a sealing block 504.

[0039] One end of the spring 503 is fixedly installed on the support rod 501, and the other end is fixedly installed on the sealing block 504, the sealing block 504 is arranged in a conical shape, and the circumferential surface of the sealing block 504 is provided with an installation groove 505.

[0040] The installation groove 505 is internally installed with sealing rings 506, and the two sealing rings 506 are respectively in abutment with the corresponding resisting plates 304.

[0041] During installation, when the installation pipe 301 and the pipe 4 gradually approach and butt joint, the sealing blocks 504 located in the inner cavities of the installation pipe 301 and the pipe 4 will first contact each other. Since the sealing blocks 504 are arranged in a conical shape, as the installation pipe 301 and the pipe 4 further approach, the two conical sealing blocks 504 will be pressed against each other, causing the sliding rod 502 to slide inside the support rod 501 and compress the spring 503. At this time, the sealing rings 506 installed in the installation groove 505 on the circumferential surface of the sealing block 504 are no longer in abutment with the resisting plates 304, so that the installation pipe 301 and the pipe 4 are in communication with each other, and at the same time, during the threaded installation and tightening of the threaded cap 303 and the pipe 4, the connection between the installation pipe 301 and the pipe 4 is more secure.

[0042] During disassembly, as the installation pipe 301 and the pipe 4 gradually separate, the elastic force of the spring 503 is gradually released, pushing the sealing block 504 and the sealing ring 506 to move towards the resisting plate 304, so that the sealing block 504 and the sealing ring 506 are in close contact with the resisting plate 304, forming a sealed defense line. The sealing ring 506 fills the small gap between the sealing block 504 and the resisting plate 304 by virtue of its good elastic deformation capability, effectively preventing gas from leaking between the sealing block 504 and the resisting plate 304. However, due to the good sealing characteristics of the sealing ring 506 and the resisting plate 304, the effective sealing and protection of harmful gases in the pipe 4 during installation and disassembly of the pressure gauge is realized, ensuring the safety and reliability of the entire operation process.
