DETAILED DESCRIPTION

[0020] The utility model will be further described below in combination with examples.

[0021] The following examples are used to illustrate the utility model, but cannot be used to limit the protection scope of the utility model. The conditions in the examples can be further adjusted according to specific conditions, and simple improvement of the method of the utility model under the concept premise of the utility model all belong to the range required to be protected by the utility model.

[0022] Please refer to Figures 1-3The utility model provides a convenient maintenance's stainless steel pressure gauge, including external pipeline 1 and stainless steel pressure gauge main part 2, the bottom of stainless steel pressure gauge main part 2 is equipped with connecting portion 3, the bottom of connecting portion 3 is equipped with connecting end 4, the top of external pipeline 1 is equipped with connecting disc 101, and connecting end 4 is wrapped in the outside of connecting disc 101 top, the outside of connecting end 4 is equipped with fixed assembly, and fixed assembly includes the multiple connecting pieces 5 of annular distribution in the outside of connecting end 4 top, and connecting piece 5 includes the rotation hook 501 rotationally connected with connecting end 4, and the bottom of rotation hook 501 is equipped with fixed end 502, and the section of connecting piece 5 is " L " shape, and the bottom fixed connection of connecting disc 101 has fixed ring 102, and the inside of fixed ring 102 is equipped with deformation cavity 1021, and the side of fixed ring 102 is equipped with butt joint groove 1022, and the top of fixed end 502 is equipped with the abutment surface 5021 of adaptation with the bottom of fixed ring 102, and one end of fixed end 502 is equipped with the butt joint convex 5022 of adaptation with butt joint groove 1022, first, ensure that external pipeline 1 and stainless steel pressure gauge main part 2 are in the state of waiting to connect, and the top of external pipeline 1 is equipped with connecting disc 101, and the bottom of stainless steel pressure gauge main part 2 is connected with connecting end 4 through connecting portion 3, and connecting end 4 is wrapped in the outside of connecting disc 101 top. This step ensures the preliminary positioning and contact between connecting end 4 and connecting disc 101, and then, connecting end 4 and connecting disc 101 are firmly connected together using fixed assembly. Fixed assembly includes multiple connecting pieces 5 that are annularly distributed on the outside of the top of connecting end 4. Each connecting piece 5 is composed of a rotation hook 501 and a fixed end 502, and has an "L" shaped cross section. The rotation hook 501 is rotationally connected with the connecting end 4, and the fixed end 502 at the bottom of the rotation hook 501 is aligned with the fixed ring 102. Then, the rotation hook 501 is gently rotated, so that the abutment surface 5021 of the fixed end 502 is tightly attached to the bottom of the fixed ring 102. At the same time that the fixed end 502 is attached to the fixed ring 102, the butt joint convex 5022 at one end of the fixed end 502 slides into the butt joint groove 1022. This step ensures that the fixed assembly is firmly locked on the connecting disc 101. Since the deformation cavity 1021 is formed in the inside of the fixed ring 102, when the fixed end 502 is pressed in, the deformation cavity 1021 will elastically deform to a certain extent, thereby absorbing the impact force during installation and ensuring that the fixed end 502 is tightly attached to the fixed ring 102. Once the installation is complete, the deformation cavity 1021 will elastically return to the original state, further consolidating the connection.

[0023] The combination structure of the rotating hook 501 and the fixed end 502 makes the connection between the stainless steel pressure gauge body 2 and the external pipeline 1 simple and fast. Without complex tools or steps, the installation can be completed, and when the stainless steel pressure gauge needs to be disassembled, the fixed end 502 can be separated from the fixed ring 102 by simply rotating the rotating hook 501. This design greatly shortens the disassembly time and improves the maintenance efficiency. The close fit between the connection end 4 and the connecting disc 101 and the firm locking of the fixed assembly ensure the sealing of the connection. Even in high-pressure or high-temperature environments, medium leakage can be effectively prevented. The design of the fixed ring 102 and the butt joint groove 1022 enhances the stability of the connection. Through the cooperation of the fixed end 502 and the butt joint groove 1022 and the elastic recovery effect of the deformation cavity 1021, it can be ensured that the stainless steel pressure gauge will not loosen or fall off during use.

[0024] The bottom of the connection end 4 is provided with a cavity matched with the connecting disc 101, and the inner wall of the cavity is provided with a circular sealing protrusion 401. The outer circle of the connecting disc 101 is provided with a sealing groove 103 matched with the sealing protrusion 401. The inside of the sealing protrusion 401 is provided with a sealing cavity 402, and the inside of the sealing cavity 402 is fixedly connected with a horizontally arranged "H" shaped sealing reset member 403. During the butt joint of the connection end 4 and the connecting disc 101, first of all, it is ensured that the cavity at the bottom of the connection end 4 can be accurately fitted on the outside of the connecting disc 101. This step ensures the preliminary positioning and contact between the connection end 4 and the connecting disc 101;

[0025] With the further butt joint of the connection end 4 and the connecting disc 101, the circular sealing protrusion 401 on the inner wall of the connection end 4 will gradually embed into the sealing groove 103 at the outer circle of the connecting disc 101. This step ensures the close fit between the connection end 4 and the connecting disc 101, thereby preventing medium leakage. During the embedding of the sealing protrusion 401 into the sealing groove 103, the "H" shaped sealing reset member 403 inside the sealing protrusion 401 will be compressed. Since the "H" shaped sealing reset member 403 has a certain elasticity, when the connection end 4 and the connecting disc 101 are completely butt jointed, it will gradually return to the original state, thereby further enhancing the sealing effect. While the sealing protrusion 401 and the sealing groove 103 are closely matched, the fixed assembly (such as the rotating hook 501 and the fixed end 502 described above) is used to firmly connect the connection end 4 and the connecting disc 101 together. This step ensures the stability and reliability of the connection;

[0026] By setting the circular sealing protrusion 401 and the sealing groove 103 matched with it, the close fit between the connecting end 4 and the connecting disc 101 is ensured. This design effectively prevents medium leakage and improves the sealing of the connection. By setting the "H" shaped sealing reset member 403 inside the sealing protrusion 401, not only the elasticity of the sealing protrusion 401 is enhanced, but also a certain compression and recovery force is provided during the connection process. This design makes the sealing effect more reliable, and even in high pressure or high temperature environment, it can also maintain good sealing performance. Since the "H" shaped sealing reset member 403 has a certain elasticity and recovery force, it can adapt to sealing grooves 103 of different sizes and shapes. This design makes the connection between the connecting end 4 and the connecting disc 101 more flexible and convenient. By optimizing the sealing structure and adding the design of the sealing reset member 403, the friction and wear between the connecting end 4 and the connecting disc 101 is effectively reduced. This design not only improves the stability and reliability of the connection, but also prolongs the service life of the pressure gauge.

[0027] The working principle and use process of the utility model are as follows: firstly, ensure that the external pipeline 1 and the stainless steel pressure gauge main body 2 are in the state of being connected, the top of the external pipeline 1 is equipped with a connecting disc 101, and the bottom end of the stainless steel pressure gauge main body 2 is connected with a connecting end 4 through a connecting part 3, and the connecting end 4 is wrapped outside the top end of the connecting disc 101. This step ensures the preliminary positioning and contact between the connecting end 4 and the connecting disc 101, and then, the connecting end 4 and the connecting disc 101 are firmly connected together by using a fixing assembly. The fixing assembly comprises a plurality of connecting pieces 5 which are annularly distributed outside the top end of the connecting end 4. Each connecting piece 5 is composed of a rotating hook 501 and a fixed end 502, and the cross section is "L" shaped, the rotating hook 501 is rotationally connected with the connecting end 4, and the fixed end 502 at the bottom end is aligned with a fixing ring 102. Then, the fixed end 502 is tightly attached to the bottom of the fixing ring 102 by rotating the rotating hook 501 gently, and at the same time that the fixed end 502 is attached to the fixing ring 102, the butt joint protrusion 5022 at one end of the fixed end 502 will slide into the butt joint groove 1022. This step ensures that the fixing assembly is firmly locked on the connecting disc 101, and since the deformation cavity 1021 is formed inside the fixing ring 102, when the fixed end 502 is pressed in, the deformation cavity 1021 will be elastically deformed to a certain extent, thereby absorbing the impact force in the installation process and ensuring the tight attachment between the fixed end 502 and the fixing ring 102. Once the installation is completed, the deformation cavity 1021 will elastically return to the original state, further consolidating the connection, and with the further butt joint of the connecting end 4 and the connecting disc 101, the circular ring-shaped sealing protrusion 401 on the inner wall of the connecting end 4 will gradually be embedded into the sealing groove 103 at the outer circle of the connecting disc 101. This step ensures the tight attachment between the connecting end 4 and the connecting disc 101, thereby preventing medium leakage, and in the process that the sealing protrusion 401 is embedded into the sealing groove 103, the "H"-shaped sealing reset member 403 inside the sealing protrusion 401 will be compressed to a certain extent. Since the "H"-shaped sealing reset member 403 has a certain elasticity, when the connecting end 4 and the connecting disc 101 are completely butt jointed, it will gradually return to the original state, thereby further enhancing the sealing effect.
