The first connecting ring 301, the second connecting ring 302 and the third connecting ring 303 are all made of rubber. There is a gap between the first connecting ring 301 and the third connecting ring 303. When the pipe or tank connected to the pressure gauge vibrates, the first connecting ring 301, the second connecting ring 302 and the third connecting ring 303 made of rubber can play a buffering function, thereby ensuring the safety of the device when in use.

[0039] In this embodiment, the buffer assembly 4 includes a fixed block 402 fixedly connected to the third connecting ring 303, a rubber block 403 is fixedly connected to the fixed block 402, one side of the rubber block 403 is provided with a transverse convex pattern 404, and a guide rod 401 is provided in the second connecting ring 302.

[0042] In this embodiment, the first connecting blocks 13 are symmetrically distributed on both sides of the first connecting ring 12, and the second connecting blocks 14 are symmetrically distributed on both sides of the second connecting ring 18. The first connecting block 13 forms a snap-fit ​​structure with the second connecting block 14 through the docking groove 15 and the rubber docking block 16. The snap-fit ​​structure on the device enables the first connecting block 13 and the second connecting block 14 to be quickly docked and disassembled, so that the protective structure composed of the first connecting block 13 and the second connecting block 14 and the first connecting ring 12 can be installed or disassembled according to the usage scenario later.

[0044] In this embodiment, the docking assembly 19 includes a first protrusion 1901 fixedly connected to the second connecting ring 18, a second spring 1902 is fixedly arranged on the first protrusion 1901, a pressure plate 1903 is slidably installed on the second connecting ring 18, the second spring 1902 is connected to the pressure plate 1903, and the second slider 1702 is provided with a groove 1904 for docking with the pressure plate 1903. The pressure plate 1903 is pressed down, and the second spring 1902 is stretched. When the pressure plate 1903 is inserted into the groove 1904 of the second slider 1702, the second connecting ring 18 rotates to drive the second slider 1702 to rotate, so as to realize the subsequent cleaning function of the pressure gauge dial.

[0046] In this embodiment, the extension assembly 21 includes a movable groove 2101 opened on the connecting rod 2003, an adjustment block 2102 is slidably installed on the movable groove 2101, an adjustment rod 2103 is slidably installed on the adjustment block 2102, a connecting frame 2104 is rotatably provided on the adjustment rod 2103, a convex lens 2105 is fixedly connected in the connecting frame 2104, a connecting handle 2106 is fixedly provided on the connecting frame 2104, and a second cleaning pad 2107 is fixedly connected to the side of the connecting frame 2104 close to the pressure gauge body 1 The movable groove 2101 and the adjustment block 2102 can change the position of the adjustment rod 2103, and the position of the adjustment rod 2103 itself can be adjusted on the adjustment block 2102, thereby making the adjustment range of the connecting frame 2104 and the convex lens 2105 wider. When in use, the connecting handle 2106 can be grasped to change the position of the convex lens 2105 so as to subsequently observe the indication of the corresponding position, and when changing the position of the connecting frame 2104, the second cleaning pad 2107 can be moved to clean the position that needs to be observed.

[0047] It should be noted that the present invention is a pressure gauge with an assembled protection mechanism. First, Figure 1-Figure 8 As shown, when the device is in use, the first connecting ring 12, the second connecting ring 18, the first slider 1701, the second slider 1702, the third slider 1703, the fourth slider 1704, the first connecting block 13 and the second connecting block 14 can be used as a protective structure outside the pressure gauge body 1, because the connection between the first slider 1701 and the second slider 1702 and the third slider 1703 and the fourth slider 1704 is the same as the connection between the first connecting block 13 and the second connecting block 14 (combined with Figure 8 It can be seen that the first connection block 13 and the second connection block 14 can be stably docked through the docking groove 15 and the rubber docking block 16. The first slider 1701 and the second slider 1702 and the third slider 1703 and the fourth slider 1704 can also be docked through the docking groove 15 and the rubber docking block 16. The device can choose to install or remove the protective structure on the pressure gauge according to the usage scenario. The pressure gauge can be cleaned by rotating the first connecting ring 12 and the second connecting ring 18. When the first connecting ring 12 rotates, it will drive the convex plate 11 to rotate, and the rubber belt 6 and the first cleaning pad 9 will rotate. The first cleaning pad 9 can clean the pressure gauge joint 10. The first connecting plate 502 and the second connecting plate 503 can slide in the fixed disk 501, so as to change the installation position of the whole device and the docking position of the first connecting plate 502 and the second connecting plate 503. After the adjustment is completed, the clamping rod 505 is pulled so that the first spring 506 is stretched, and the clamping rod 505 is inserted into the installation holes 504 of the first connecting plate 502 and the second connecting plate 503 to adapt to different fixed positions for use.

[0048] like Figure 4-Figure 12As shown, the connection assembly 17 and the second connection ring 18 are connected by the connection assembly 19. When the second connection ring 18 rotates, the connection assembly 17 is driven to rotate, and the pressure gauge dial is cleaned by the cleaning assembly 20 on the connection assembly 17. The pressing plate 1903 is pressed, and the second spring 1902 is stretched. When the pressing plate 1903 is inserted into the groove 1904 of the second slider 1702, the second connection ring 18 rotates to drive the second slider 1702 to rotate. Since the connection rod 2003 is in sliding connection with the second slider 1702 and the fourth slider 1704, the rotation of the second slider 1702 drives the fourth slider 1704, the connection rod 2003 and the cleaning plate 2004 to rotate. The third spring 2002 on the second protrusion 2001 can keep the cleaning plate 2004 in close contact with the pressure gauge dial, so that the device can clean the pressure gauge dial while rotating the second connection ring 18 of the protective structure. The adjusting block 2102 in the movable groove 2101 can adjust its position, thereby changing the position of the adjusting rod 2103, and the adjusting rod 2103 can slide on the adjusting block 2102, thereby making the adjustment range of the connecting frame 2104 and the convex lens 2105 wider, and the connecting handle 2106 is used to change the position of the convex lens 2105, so as to subsequently magnify and observe the indications of different positions on the dial, and when changing the position of the connecting frame 2104, the second cleaning pad 2107 can move and clean the position to be observed. When the pipeline or tank connected to the pressure gauge vibrates, the first connecting ring 301 and the third connecting ring 303 with pores are provided, and the first connecting ring 301, the second connecting ring 302 and the third connecting ring 303 made of rubber material enable the pressure gauge to play a buffering function to ensure the safety of the device when in use. The guide rod 401 can realize the guiding function. When the device vibrates, the third connecting ring 303 will move up and down on the guide rod 401. The transverse convex grooves 404 on the rubber block 403 make the rubber block 403 move below the guide rod 401. The transverse convex grooves 404 contact the guide rod 401, and the movement resistance of the rubber block 403 is relatively large. When the rubber block 403 moves above the guide rod 401, the transverse convex grooves 404 do not contact the guide rod 401, and the movement resistance of the rubber block 403 is relatively small, thereby improving the buffering and vibration reduction effects of the device.

[0049] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
