Description

Technical Field

[0001] This application relates to the field of pressure gauge technology, specifically to a sleeve mounting device for a pressure gauge interface. Background Technology

[0002] When a pressure gauge is connected to a pipeline, a bend is added between the pressure gauge and the pipeline. This connection is called a pressure gauge bend (or simply gauge bend), formally known as a buffer tube. It's a fitting used to connect the pressure gauge to the equipment or pipeline it measures, buffering the instantaneous impact of the measured medium on the pressure gauge's Bourdon tube. This effectively protects the mechanical structure of the digital display or the pressure sensor from damage, extending its service life.

[0003] The sleeve is threaded onto the pressure gauge via a screw-on connection. Traditionally, a wrench is used to clamp and tighten the connection between the sleeve and the pressure gauge for effective fixation. When one person performs this operation, one hand is needed to align the pressure gauge and the sleeve, while the other hand uses a wrench to clamp and tighten the connection. This method increases physical exertion when repeatedly connecting the pressure gauge and the sleeve, resulting in reduced installation efficiency. Utility Model Content

[0004] The purpose of this application is to provide a sleeve installation device for a pressure gauge interface, in order to solve the problem mentioned in the background art that when a person performs the above-mentioned operation, one hand is needed to align the pressure gauge and the sleeve, and the other hand uses a hand wrench to clamp and turn the pressure gauge and the sleeve. This method increases the physical exertion of the human body and reduces the installation efficiency when connecting the pressure gauge and the sleeve repeatedly.

[0005] To achieve the above objectives, this application provides the following technical solution: a sleeve installation device for a pressure gauge interface, comprising: a fixed base, a first positioning block, a second positioning block, a limiting and pushing mechanism, a positioning mechanism, and a clamping and rotating mechanism. The placement assembly includes a fixed base, a first positioning block disposed on one side above the fixed base, and a second positioning block disposed on the other side above the fixed base. The first positioning block has a groove inside, and a horizontal through hole is formed on the inner wall of the groove. The second positioning block has a groove for placing the sleeve. The limiting and pushing mechanism is disposed inside the horizontal through hole of the first positioning block. The limiting and pushing mechanism includes a third positioning block slidably connected to the groove of the first positioning block. The third positioning block has a groove inside that is adapted to the pressure gauge. A guide rod is welded to the outer wall of the third positioning block. The guide rod passes through the horizontal through hole of the first positioning block. A spring is sleeved on the guide rod. A connecting block is welded to one end of the guide rod, and a protrusion is welded to the top of the connecting block. The positioning mechanism is disposed above the first positioning block, and the clamping and rotating mechanism is disposed on the outer wall of the second positioning block.

[0006] By adopting the above technical solution, the pressure gauge and the sleeve can be quickly and tightly connected.

[0007] Preferably, the positioning mechanism includes a fixing plate welded above the first positioning block, and the fixing plate has an "L" shaped cross-section.

[0008] By adopting the above technical solution, the external structure can be stably and securely connected.

[0009] Preferably, the positioning mechanism further includes a stop block rotatably connected above the fixed plate via a shaft, and one end of the stop block is in contact with the protrusion.

[0010] By adopting the above technical solution, the bump can be positioned by rotation.

[0011] Preferably, the positioning mechanism further includes a handle welded above the stop.

[0012] By adopting the above technical solution, it is possible to provide a handheld device that can move the connected structure together.

[0013] Preferably, the clamping and rotating mechanism includes a slide rail welded to the outer wall of the second positioning block, and the slide rail has an opening for the movement of the sleeve.

[0014] By adopting the above technical solution, it is possible to achieve stable rotation on the slide rail.

[0015] Preferably, the clamping and rotating mechanism further includes a slider rotatably connected to the slide rail.

[0016] By adopting the above technical solution, the connected structure can be rotated and operated in tandem.

[0017] Preferably, the clamping and rotating mechanism further includes a clamping assembly fixed on the outer wall of the slider, the clamping assembly being composed of a threaded rod driving clamping blocks at both ends of the rod to move on the round rod.

[0018] By adopting the above technical solution, the pressure gauge and the sleeve connection can be clamped and fixed by a knob.

[0019] In summary, this application has the following beneficial effects: By providing a first positioning block, a second positioning block, and a limiting and pushing mechanism, the pressure gauge can be moved by pushing it horizontally when the clamping and rotating mechanism clamps and rotates the pressure gauge at the connection between the pressure gauge and the sleeve. This ensures that the pressure gauge remains stably attached to the installation position between the pressure gauge and the sleeve. After the first and second positioning blocks position the pressure gauge and the sleeve, manual positioning is not required; effective positioning is achieved simply by placing the gauge. This prevents displacement when the pressure gauge is moved later. This method reduces the physical effort required for installation, thereby increasing installation efficiency.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The following is in conjunction with the appendix Figure 1-4 The embodiments of this application will be described in further detail.

[0027] Example 1

[0028] Please see Figures 1-4 This embodiment provides a technical solution: a sleeve installation device for a pressure gauge interface, including: a fixed base 1, a first positioning block 2, a second positioning block 3, a limiting and pushing mechanism 4, a positioning mechanism 5, and a clamping and rotating mechanism 6;

[0029] The placement component includes a fixed base 1, a first positioning block 2 disposed on one side above the fixed base 1, and a second positioning block 3 disposed on the other side above the fixed base 1. The first positioning block 2 has a groove inside, and a horizontal through hole is formed on the inner wall of the groove of the first positioning block 2. The second positioning block 3 has a groove for placing the sleeve.

[0030] The limiting and pushing mechanism 4 is located inside the horizontal through hole of the first positioning block 2. The limiting and pushing mechanism 4 includes a third positioning block 401 slidably connected in the groove of the first positioning block 2. The third positioning block 401 has a groove adapted to the pressure gauge. A guide rod 402 is welded to the outer wall of the third positioning block 401. The guide rod 402 passes through the horizontal through hole of the first positioning block 2. A spring 403 is sleeved on the guide rod 402. A connecting block 404 is welded to one end of the guide rod 402. A protrusion 405 is welded to the top of the connecting block 404. The positioning mechanism 5 is located above the first positioning block 2. The clamping and rotating mechanism 6 is located on the outer wall of the second positioning block 3.

[0031] The pressure gauge is positioned by the limiting and pushing mechanism 4 inside the first positioning block 2 above the fixed base 1. Then, the sleeve is positioned by the second positioning block 3. At this time, by unlocking the positioning mechanism 5, the limiting and pushing mechanism 4 can drive the pressure gauge to fit against the sleeve. Then, the clamping and rotating mechanism 6 clamps and rotates the connection between the pressure gauge and the sleeve, thereby driving the sleeve and the pressure gauge to form a threaded connection.

[0032] The pressure gauge is placed inside the third positioning block 401. The third positioning block 401 can move stably horizontally inside the horizontal through hole of the first positioning block 2 through the connection of the guide rod 402. When the protrusion 405 above the connecting block 404 of the guide rod 402 is no longer positioned by the positioning mechanism 5, the connecting block 404 is pulled by the spring 403 on the outside of the guide rod 402, thereby driving the pressure gauge inside the third positioning block 401 at the other end of the guide rod 402 to move and fit against the connecting part of the sleeve.

[0033] Example 2

[0034] Please see Figures 1-4 This embodiment provides a technical solution: a sleeve installation device for a pressure gauge interface, including: a fixing plate 501, a stop block 502 and a handle 503;

[0035] The positioning mechanism 5 includes a fixing plate 501 welded above the first positioning block 2. The fixing plate 501 has an "L" shaped cross section. A stop block 502 is rotatably connected above the fixing plate 501 via a shaft. One end of the stop block 502 is in contact with the protrusion 405. The positioning mechanism 5 also includes a handle 503 welded above the stop block 502.

[0036] By rotating the handle 503, the stop block 502 is rotated from a horizontal state to a vertical state inside the fixed plate 501. At this time, the stop block 502 no longer continues to position the protrusion 405.

[0037] Example 3

[0038] Please see Figures 1-4 This embodiment provides a technical solution: a sleeve installation device for a pressure gauge interface, including: a slide rail 601, a slider 602 and a clamping assembly 603;

[0039] The clamping and rotating mechanism 6 includes a slide rail 601 welded to the outer wall of the second positioning block 3, an opening for the movement of the sleeve on the slide rail 601, a slider 602 rotatably connected to the slide rail 601, and a clamping assembly 603 fixed on the outer wall of the slider 602. The clamping assembly 603 is composed of a threaded rod that drives the clamping blocks at both ends of the rod to move on the round rod.

[0040] Through the operation of the clamping assembly 603, the threaded rod rotates and drives the clamping block on the rod to move stably on the round rod, thereby clamping the rotatable hexagonal block on the sleeve. The slider 602 rotates on the slide rail 601, which synchronously drives the clamping assembly 603 to rotate. At this time, the rotatable hexagonal block on the clamped sleeve is in contact with the pressure gauge, and the threaded tube on the pressure gauge is rotated and threadedly connected to the threaded groove on the inner wall of the rotatable hexagonal block on the sleeve.

[0041] The implementation principle of the sleeve installation device for the pressure gauge interface in this application is as follows:

[0042] First, the pressure gauge is positioned by the limiting and pushing mechanism 4 inside the first positioning block 2 above the fixed base 1. Then, the sleeve is positioned by the second positioning block 3. At this time, by unlocking the positioning mechanism 5, the limiting and pushing mechanism 4 can drive the pressure gauge to fit against the sleeve. Then, the clamping and rotating mechanism 6 clamps and rotates the connection between the pressure gauge and the sleeve, thereby driving the sleeve and the pressure gauge to form a threaded connection.

[0043] Secondly, the pressure gauge is placed inside the third positioning block 401. The third positioning block 401 can move stably horizontally inside the horizontal through hole of the first positioning block 2 through the connection of the guide rod 402. When the protrusion 405 above the connecting block 404 of the guide rod 402 is no longer positioned by the positioning mechanism 5, the stop block 502 is rotated from a horizontal state to a vertical state inside the fixed plate 501 by rotating the handle 503. At this time, the stop block 502 no longer positions the protrusion 405. At this time, the connecting block 404 is lifted by the spring 403 on the outside of the guide rod 402, thereby driving the pressure gauge inside the third positioning block 401 at the other end of the guide rod 402 to move and fit against the connecting part of the sleeve.

[0044] Finally, through the operation of the clamping assembly 603, the threaded rod rotates and drives the clamping block on the rod to move stably on the round rod, thereby clamping the rotatable hexagonal block on the sleeve. The slider 602 rotates on the slide rail 601, which synchronously drives the clamping assembly 603 to rotate. At this time, the rotatable hexagonal block on the clamped sleeve is in contact with the pressure gauge, and the threaded tube on the pressure gauge is rotated and threadedly connected to the threaded groove on the inner wall of the rotatable hexagonal block on the sleeve.

[0045] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
