Description

Technical Field

[0001] This utility model relates to the technical field of chemical production equipment, and more specifically, it relates to an adjustable pressure gauge fastening device. Background Technology

[0002] A pressure gauge is an instrument used to measure the pressure of fluids (gas or liquid). It converts pressure into mechanical displacement through the deformation of an elastic element (such as a Bourdon tube or diaphragm), and then displays the value via a pointer or digital display. Its core components include a pressure port, transmission mechanism, dial, and housing. Common types include mechanical, electronic, and differential pressure gauges, and they are widely used in industries such as industrial, energy, chemical, and medical fields. The main function of a pressure gauge is to monitor system pressure in real time, ensuring that equipment operates within safe ranges. For example, detecting abnormal pressure in pipelines can prevent leaks or explosions; controlling pressure in boilers can avoid the risk of overpressure; and maintaining precise pressure in medical equipment (such as ventilators) ensures patient safety. In addition, it is used for process control (such as pressure regulation in chemical reactions) and efficiency evaluation (such as compressor performance testing), making it an important tool for ensuring production safety and improving process accuracy. When selecting a pressure gauge, factors such as range, accuracy, media compatibility, and environmental adaptability must be considered. A search revealed an existing publication (CN223050770U) disclosing an adjustable pressure gauge fastening device, comprising a main pipe clamp secured by a first set bolt. A vertical support column is provided on one side of the outer surface of the main pipe clamp, and a support column sleeve is slidably fitted onto the vertical support column. A second set bolt is provided on the side wall of the support column sleeve. A transverse support column is fixed to the side wall of the support column sleeve opposite the second set bolt, and a pressure gauge tube clamp is fixed to the end of the transverse support column. The pressure gauge tube clamp is secured by a third set bolt, and a fourth set bolt for fixing the pressure gauge is provided on the side wall. This utility model expands the applicability of pressure gauge fastening devices through the inclusion of a main pipe clamp and a pressure gauge tube clamp. The vertical support column and support column sleeve provide strong adjustability for the installation position of the pressure gauge.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the prior art: The aforementioned device, which uses components such as the main pipe clamp and the first set bolt for locking, is difficult to adjust according to the diameter of the pressure gauge, thus limiting its application range. When the required fixing radius is larger or smaller than the radius of the main pipe clamp, it cannot be clamped and fixed, requiring the replacement of the clamp, which is time-consuming and labor-intensive, and needs to be improved.

[0004] Therefore, an adjustable pressure gauge fastening device is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable pressure gauge fastening device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pressure gauge fastening device, comprising a fastening mechanism, wherein the fastening mechanism comprises a circular plate, a clamping block is provided on one side of the circular plate, and a sliding groove is provided on the side of the circular plate near the clamping block; It also includes an adjustment mechanism for adjusting the distance of the clamping block according to the size of the pressure gauge. The adjustment mechanism includes a fixed plate and a slider. The slider is slidably connected to the inner wall of the groove. One end of the slider is fixedly connected to the clamping block. The fixed plate is fixedly connected to the side of the circular plate away from the clamping block. A torsion spring rod is fixedly connected to the inner wall of the fixed plate. A torsion bar is fixedly connected to the end of the torsion spring rod near the fixed plate. A rotating rod passes through the side of the fixed plate near the circular plate and is fixedly connected to the rotating rod. A connecting rod is rotatably connected to the end of the rotating rod away from the fixed plate. A short rod passes through the end of the connecting rod away from the rotating rod and is rotatably connected to the short rod. The end of the short rod away from the connecting rod is fixedly connected to the end of the slider away from the clamping block. The clamping mechanism is used to press down and fix the pressure gauge after it has been clamped.

[0007] Preferably, the connecting rod is located between the fixed plate and the circular plate.

[0008] Preferably, the connecting rod is L-shaped, and the number of connecting rods is several, arranged in pairs, and is symmetrical about the center point of the fixed plate.

[0009] Preferably, the clamping mechanism includes a slide rod, one end of which is fixedly connected to a pressure plate, the end of which is away from the pressure plate passes through a clamping block and is slidably connected to the clamping block, the inner wall of the slide groove is provided with an inclined groove, and a positioning rod passes through one side of the slide rod and is rotatably connected to the positioning rod.

[0010] Preferably, the number of sliding rods is four, arranged in pairs and symmetrical to each other along the vertical central axis of the circular plate, and the number of pressure plates is the same as the number of sliding rods.

[0011] Preferably, the end of the positioning rod away from the slide rod is slidably connected to the inner wall of the inclined groove, and the end of the slide rod away from the pressure plate is located inside the groove.

[0012] Preferably, the torsion spring rod is initially in a stretched state, and the circular plate is located between the clamping block and the fixing plate.

[0013] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this adjustable pressure gauge fastening device achieves the effect of adjusting the clamping force of the rotating torsion bar in conjunction with components such as the fixed plate, torsion spring rod, and rotating rod. The rotating torsion bar drives the fixed plate to rotate via the torsion spring rod, which in turn causes the fixed plate to slide within the groove via a connecting rod. This allows the slider to move the clamping block horizontally, achieving the effect of clamping adjustment according to the diameter of the pressure gauge. It eliminates the need to replace the clamp when the fixed radius is larger or smaller than the radius of the main pipe clamp, saving time and effort.

[0014] Compared with existing technologies, this adjustable pressure gauge fastening device uses the force of the clamping block displacement in conjunction with components such as the slide rod, pressure plate, and positioning rod. This allows the clamping block to move horizontally, causing the slide rod to move horizontally, which in turn causes the pressure plate to move horizontally. Simultaneously, the slide rod moves the positioning rod horizontally, which in turn causes the positioning rod to move vertically through the inclined groove, thus causing the slide rod to move vertically, which in turn causes the pressure plate to move vertically. This achieves the effect of vertically limiting the pressure gauge. Attached Figure Description

The adjusting mechanism 2 includes a fixing plate 201 and a slider 207, the slider 207 being slidably connected to the inner wall of the sliding groove 103, one end of the slider 207 being fixedly connected to the clamping block 102, and the fixing plate 201 being fixedly connected to the side of the circular plate 101 away from the clamping block 102, the inner wall of the fixing plate 201 being... A torsion spring rod 202 is fixedly connected. A torsion bar 203 is fixedly connected to one end of the torsion spring rod 202 near the fixed plate 201. A rotating rod 204 passes through the side of the fixed plate 201 near the circular plate 101 and is fixedly connected to the rotating rod 204. A connecting rod 205 is rotatably connected to the end of the rotating rod 204 away from the fixed plate 201. A short rod 206 passes through the end of the connecting rod 205 away from the rotating rod 204 and is rotatably connected to the short rod 206. The end of the short rod 206 away from the connecting rod 205 is fixedly connected to the end of the slider 207 away from the clamping block 102. A clamping mechanism 3 is used to press down and fix the pressure gauge after it is clamped.

[0023] Specifically, the slider 207 slides within the groove 103, thereby causing the clamping block 102 to move towards the center of the circular plate 101.

[0024] Example 2: Based on Example 1, the solution in Example 1 is further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, the connecting rod 205 is located between the fixed plate 201 and the circular plate 101.

[0025] As a preferred embodiment, the connecting rod 205 is L-shaped, and there are several connecting rods 205 in pairs, which are symmetrical about the center point of the fixed plate 201. The above design is beneficial to drive the short rod 206 to move through the L-shaped connecting rod 205, so that the short rod 206 drives the slider 207 to slide in the groove 103.

[0026] In a preferred embodiment, the clamping mechanism 3 includes a slide rod 301, one end of which is fixedly connected to a pressure plate 302, and the other end of the slide rod 301 away from the pressure plate 302 passes through the clamping block 102 and is slidably connected to the clamping block 102. An inclined groove 303 is provided on the inner wall of the slide groove 103, and a positioning rod 304 passes through one side of the slide rod 301 and is rotatably connected to the positioning rod 304. The above design is beneficial for clamping and limiting the pressure gauge in the vertical direction.

[0027] In a preferred embodiment, there are four slide rods 301, arranged in pairs and symmetrical to each other along the vertical central axis of the circular plate 101. The number of pressure plates 302 is the same as the number of slide rods 301. The above design is beneficial to use the slide rods 301 to drive the pressure plates 302 to move vertically, thereby limiting the pressure gauge.

[0028] In a preferred embodiment, the end of the positioning rod 304 away from the slide rod 301 is slidably connected to the inner wall of the inclined groove 303, and the end of the slide rod 301 away from the pressure plate 302 is located inside the sliding groove 103. The above design is beneficial to allow the positioning rod 304 to drive the slide rod 301 to move vertically by means of the inclination angle of the inclined groove 303.

[0029] In a preferred embodiment, the torsion spring rod 202 is initially in a stretched state, and the circular plate 101 is located between the clamping block 102 and the fixing plate 201. This design is advantageous because the torsion of the torsion spring rod 202 drives the clamping block 102 to clamp and limit the pressure gauge in the horizontal direction.

[0030] The working process of this utility model is as follows: First, rotate the torsion bar 203, causing the torsion bar 203 to drive the torsion spring rod 202 to rotate, which in turn causes the torsion spring rod 202 to drive the fixed plate 201 to rotate, thereby causing the fixed plate 201 to drive the rotating rod 204 to rotate, which in turn causes the rotating rod 204 to drive the connecting rod 205 to rotate, which in turn causes the connecting rod 205 to drive the short rod 206 to rotate, which in turn causes the short rod 206 to drive the slider 207 to rotate. At this time, the slider 207 will be limited by the slide groove 103, thereby causing the slider 207 to move horizontally within the slide groove 103, which in turn causes the slider 207 to drive the clamping block 102 to move horizontally, thereby causing the clamping block 102 to move away from the center of the circular plate 101. Then, place the pressure gauge to be clamped on the circular plate 101, and then release the torsion bar 203. At this time, the torsion bar 203 will rotate. 3. The pressure gauge is reset by the resetting property of the torsion spring rod 202, thereby clamping the pressure gauge with the clamping block 102. This achieves the effect of clamping and adjusting according to the diameter of the pressure gauge, eliminating the need to replace the clamp when the fixed radius is greater or less than the radius of the main pipe clamp, saving time and effort. At the same time, it also achieves the effect of clamping and fixing the pressure gauge in the horizontal direction. When the clamping block 102 moves closer to the center of the circular plate 101, it causes the clamping block 102 to drive the slide rod 301 to move horizontally, which in turn causes the slide rod 301 to drive the pressure plate 302 to move horizontally. Simultaneously, the slide rod 301 drives the positioning rod 304 to move horizontally, which in turn causes the positioning rod 304 to drive the slide rod 301 to move vertically through the inclined groove 303, which in turn causes the slide rod 301 to drive the pressure plate 302 to move vertically, achieving the effect of clamping and limiting the pressure gauge in the vertical direction.

[0031] The above describes the working principle of this adjustable pressure gauge fastening device.
