Furthermore, holding the barometer by hand requires operators to maintain a specific posture for extended periods, increasing their workload. Handheld operation also causes shaking, affecting test accuracy and reducing work efficiency.

[0004] The above-mentioned method of fixing the barometer has problems such as affecting the testing accuracy and low work efficiency. Utility Model Content

[0035] See Figure 1 , Figure 1 A schematic diagram of the structure of a pressure gauge test fixing device according to an embodiment of this application is shown.

[0036] An embodiment of this application provides a barometer test fixing device, including a base 10, a fixing bracket 20, an elastic reset component 30, an operating component 40, and a rotating connecting component 50. The components cooperate with each other to fix the barometer and adjust its rotation angle.

[0037] In this embodiment, the base 10 is used to fix it to the workbench surface. The fixing bracket 20 includes an upper clamping piece 21 and a lower clamping piece 22, the lower clamping piece 22 being movable relative to the upper clamping piece 21 in a vertical direction. The elastic reset member 30 includes a fixing part 31 connected to the upper clamping piece 21 and a movable part 32 acting on the lower clamping piece 22. The operating member 40 is fixed to the bottom of the lower clamping piece 22. The rotating connector 50 includes a rotatable first connecting part 51 and a second connecting part 52, the first connecting part 51 being connected to the fixing bracket 20, and the second connecting part 52 being connected to the top end of the base 10.

[0038] The base 10 includes two parallel columns 11, which are made of metal. At the top of each column 11, there is a rotating connector 50, which is connected to a fixed bracket 20, allowing the fixed bracket 20 to rotate relative to the base 10 for easy adjustment of the pressure gauge angle.

[0039] The bottom end of the column 11 is fixed to the workbench surface via a mounting flange. The mounting flange has multiple mounting holes, and the column 11 is firmly fixed to the workbench using bolts or other means to prevent shaking or displacement. Alternatively, the mounting flange at the bottom end of the column 11 can be glued to the workbench surface.

[0040] The fixed bracket 20 consists of an upper clamping plate 21 and a lower clamping plate 22, both of which are made of metal. The lower clamping plate 22 can move vertically relative to the upper clamping plate 21 to increase or decrease the clamping space, so that the fixed bracket 20 can accommodate barometers of different sizes.

[0041] The elastic reset member 30 includes a fixed part 31 connected to the upper clamping plate 21 and a movable part 32 acting on the lower clamping plate 22. The fixed part 31 is bolted to the upper clamping plate 21, and the movable part 32 contacts the lower clamping plate 22 and applies an upward elastic force. When the lower clamping plate 22 moves downward, the elastic reset member 30 is compressed, storing elastic potential energy. When the operating member 40 is released, the elastic reset member 30 releases the elastic potential energy, pushing the lower clamping plate 22 upward to return to its initial position, thereby achieving automatic clamping of the pressure gauge.

[0042] The operating component 40 is a pull ring made of metal. One end of the pull ring is fixed to the bottom of the lower clamping plate 22 by welding. Pulling the pull ring downwards causes the lower clamping plate 22 to move downwards, increasing the clamping space.

[0043] The rotating connector 50 includes a rotatable first connecting part 51 and a second connecting part 52. The first connecting part 51 is connected to the fixed bracket 20, and the second connecting part 52 is connected to the column 11 at the top of the base 10. The first connecting part 51 and the second connecting part 52 can rotate relative to each other, allowing the operator to adjust the angle of the pressure gauge according to actual needs, facilitating observation of the pressure gauge reading and conducting experimental operations.

[0044] In the specific implementation process, when a barometer test is required, the operator pulls down the pull ring, causing the lower clamp 22 to move downwards, at which point the elastic reset member 30 is compressed. The barometer is placed between the upper clamp 21 and the lower clamp 22, and then the pull ring is released. The elastic reset member 30 releases its elastic potential energy, pushing the lower clamp 22 upwards, which then cooperates with the upper clamp 21 to clamp the barometer.

[0045] When it is necessary to adjust the angle of the barometer, the operator can manually rotate the fixed bracket 20. The fixed bracket 20 rotates relative to the base 10 to adjust the barometer to the appropriate angle.

[0046] As described above, the barometer testing and fixing device, through the coordinated operation of the base 10, fixing bracket 20, elastic reset component 30, operating component 40, and rotating connecting component 50, achieves the fixation and angle adjustment of the barometer, avoiding the problem of easy damage caused by placing the barometer directly on the test bench. Simultaneously, the clamping action of the fixing bracket 20 reduces the possibility of loosening at the connection between the barometer and the pressure pipe, improving the accuracy and reliability of the test. Furthermore, the operator does not need to hold the barometer, reducing labor intensity and improving work efficiency.

[0047] Combination Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a barometer testing and fixing device provided in one embodiment of this application. In some embodiments, the fixing part 31 is a spring shaft, one end of which is connected to one end of the upper clamping piece 21, and the other end of which is connected to one end of the lower clamping piece 22.

[0048] Specifically, the fixing part 31 is a spring shaft made of carbon steel. One end of the spring shaft is bolted to one end of the upper clamping plate 21 to ensure a reliable connection. The other end of the spring shaft is connected to one end of the lower clamping plate 22, providing guidance and support for the movement of the lower clamping plate 22.

[0049] In one embodiment, the movable part 32 is a spring, which is sleeved on a spring shaft, with one end of the spring abutting against the lower clip 22 and the other end of the spring connected to the limiting part of the spring shaft.

[0050] Specifically, the movable part 32 is a spring, which is sleeved on a spring shaft. One end of the spring abuts against the lower clamp 22, and the other end of the spring is connected to the limiting part of the spring shaft. When an external force causes the lower clamp 22 to move downward, the spring is compressed. In its natural state, the spring force keeps the lower clamp 22 in its initial position near the upper clamp 21. When the lower clamp 22 moves downward, the spring is compressed, storing elastic potential energy. When the external force disappears, the spring releases the elastic potential energy, pushing the lower clamp 22 upward to return to its initial position, thus achieving automatic clamping of the pressure gauge.

[0051] Combination Figure 2 As shown, Figure 2 This is a side view of a pressure gauge testing and fixing device provided in one embodiment of this application. In some embodiments, it also includes a U-shaped connecting bracket 53, whose opposite side walls are respectively connected to the top and bottom ends of the spring shaft.

[0052] Specifically, the U-shaped connecting frame 53 is made of metal. The two opposing side walls of the U-shaped connecting frame 53 are welded to the top and bottom ends of the spring shaft, respectively, ensuring the stability of the spring shaft. The bottom of the U-shaped connecting frame 53 has mounting holes that match the first connecting part 51 of the rotating connector 50, and is connected to the first connecting part 51 by bolts or the like. Alternatively, the bottom of the U-shaped connecting frame 53 is welded to the first connecting part 51.

[0053] In one embodiment, the first connecting part 51 is fixedly connected to the bottom of the U-shaped connecting frame 53; the second connecting part 52 is fixed to the top of the base 10.

[0054] Specifically, the rotating connector 50 is a friction hinge structure, including a first connecting part 51, a second connecting part 52, and an intermediate friction assembly.

[0055] The first connecting part 51 is bolted to the bottom of the U-shaped connecting frame 53 for easy disassembly and installation. The first connecting part 51 has multiple mounting holes, allowing adjustment of its connection position with the U-shaped connecting frame 53 as needed. The second connecting part 52 is bolted to the top of the base 10.

[0056] The friction assembly, located between the first connecting part 51 and the second connecting part 52, consists of friction plates and an adjusting bolt. By rotating the adjusting bolt, the pressure between the friction plates can be adjusted, thereby changing the rotational resistance of the rotating connecting part 50. When it is necessary to adjust the angle of the pressure gauge, the operator can manually rotate the fixed bracket 20 to overcome the frictional resistance and adjust the pressure gauge to the appropriate position; after adjustment, the frictional resistance can keep the angle of the pressure gauge stable and prevent it from rotating on its own.

[0057] Combination Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a barometer testing and fixing device provided in one embodiment of this application. In some embodiments, the upper clamp 21 and the lower clamp 22 are provided with arc-shaped clamping grooves 23 on their opposite sides.

[0058] Specifically, the barometer has a ring-shaped outer periphery with an arc-shaped outer surface. The upper clamp 21 and lower clamp 22 each have arc-shaped clamping grooves 23 on their opposite sides to fit snugly against the outer periphery of the barometer, improving clamping stability. The shape and size of the clamping portions of the upper clamp 21 and lower clamp 22 are adaptively adjusted according to the shape of the corresponding barometer.

[0059] In one embodiment, the upper clamping piece 21 and the lower clamping piece 22 are arc-shaped structures arranged opposite to each other, and the opposite sides of the two arc-shaped structures are respectively provided with arc-shaped clamping grooves 23.

[0060] Specifically, the upper clamp 21 and lower clamp 22 are oppositely arranged arc-shaped structures. These arc-shaped structures better conform to the shape of the barometer, improving clamping stability. Each of the two arc-shaped structures has an arc-shaped clamping groove 23 on its opposite side. The surface of the clamping groove 23 is covered with a rubber layer, which is tightly adhered to the clamping groove 23 with adhesive. The rubber layer increases friction with the barometer, preventing slippage and also acts as a buffer, avoiding damage to the barometer surface during clamping.

[0061] Both the upper clamp 21 and the lower clamp 22 are made of aluminum alloy, which reduces the overall weight of the device.

[0062] In one embodiment, the top end of the spring shaft is provided with a threaded section, and the upper clamp 21 is fixed to the threaded section by a nut 33.

[0063] Specifically, the top of the spring shaft has a threaded section, and the upper clamping plate 21 is fixed to the threaded section by a nut 33. The nut 33 fits tightly with the threaded section to ensure that the upper clamping plate 21 is stably positioned on the spring shaft. The area of ​​the bottom end of the spring shaft is larger than the area of ​​the mounting hole of the corresponding lower clamping plate 22. The bottom end of the spring shaft is located outside the lower clamping plate 22, and its top end passes through the mounting hole and is fixed to the upper clamping plate 21 by a nut 33.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
