Description

Technical Field

[0001] The utility model relates to the technical field of pressure gauges, in particular to a shock-absorbing pressure gauge. Background Art

[0002] Pressure gauges are instruments that use elastic elements as sensitive elements to measure and indicate pressures higher than the ambient pressure. They are widely used in almost all industrial processes and scientific research fields. They can be found everywhere in the fields of heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle repair and maintenance shops.

[0003] For example, patent publication number CN213956653U discloses a novel shock-absorbing automatic sensing pressure gauge, the key points of its technical solution are: it includes a pressure gauge and a connecting pipe, the connecting pipe is fixedly connected to the outer ring wall of the pressure gauge; and, a shock-proof component, which includes a shock-absorbing ring and a shock-absorbing plate, a fixed plate is arranged on the connecting pipe, the shock-absorbing ring and the shock-absorbing plate are nested in the connecting pipe and are fixedly connected, the bottom of the shock-absorbing plate is connected to the top of the fixed plate, and the inner wall of the shock-absorbing ring is fixedly connected to the pressure gauge, which protects the pressure gauge from external damage and can also ensure that the pressure gauge is not affected when some vibrating instruments are working, thereby improving the measurement accuracy of the pressure gauge, and the relative rotational jitter amplitude of the pressure gauge and the shock-proof device can be adjusted as needed to ensure that the pressure gauge will not be damaged due to torque when it shakes violently.

[0004] However, the above-mentioned new shock-absorbing automatic sensing pressure gauge uses multiple groups of springs for shock absorption to achieve the normal operation of the pressure gauge shock absorption. When the pressure gauge and the shock-absorbing device are working, they will follow the vibration to absorb the shock. The shock-absorbing device itself will vibrate. At the same time, the vibration of the device will generate relative noise, so the shock absorption effect is not good enough. In addition, the pressure gauge is a precision device and lacks a protective device to protect it. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-4 The utility model provides a shock-absorbing pressure gauge: it includes a box body 1, two groups of air spring shock absorbers 12 are arranged under the box body 1, and the bottom surface of each air spring shock absorber 12 is fixedly connected with a sound insulation damping plate 13, and a pressure gauge 10 is arranged inside the box body 1. The inner wall of the box body 1 is fixedly connected with a sound insulation cotton board 9, and the inner wall of the sound insulation cotton board 9 is fixedly connected with an isolation plate 11. The upper surface and the bottom surface of the sound insulation cotton board 9 are fixedly connected with the inner top wall and the inner bottom wall of the box body 1. By setting the box body 1, the pressure gauge 10 can be fixed inside to protect the pressure gauge 10. At the same time, the air spring shock absorber 12 can support the box body 1, so that when vibrating, the air spring shock absorber 12 can dampen the box body 1 and the pressure gauge 10, and through the sound insulation damping plate 13, the vibration and noise can be further reduced, and through the sound insulation cotton board 9 and the isolation plate 11, the noise generated by the vibration outside the box body 1 can be isolated, so that the pressure gauge 10 can be used stably.

[0030] The upper surface of the box body 1 is fixedly connected with a mounting plate 5, and the upper surface of the mounting plate 5 is fixedly connected with a traction ring 6. The mounting plate 5 can be fixed on the box body 1 and the traction ring 6 is fixed, so that the staff can move the box body 1 through the traction ring 6 when moving the box body 1, thereby improving the convenience of moving the box body 1. The front of the box body 1 is movably hinged with an opening and closing door 4, and the front of the opening and closing door 4 is fixedly connected with a handle 3. The opening and closing door 4 can open or close the box body 1, so that the pressure gauge 10 can be better protected and maintained, and the handle 3 can be used to facilitate the staff to open or close the opening and closing door 4. The inner wall of the opening and closing door 4 is clamped with a perspective plate 2, and the perspective plate 2 needs to be in a glass perspective shape. The perspective plate 2 can facilitate the staff to observe the working status of the pressure gauge 10 in the box body 1, thereby achieving the effect of convenient use.

[0031] A wiring tube 7 is provided on the left side of the box body 1, and the right end of the wiring tube 7 passes through the sound insulation cotton board 9 and the isolation board 11 of the box body 1 in sequence and extends to the interior of the box body 1. A protective cover 8 is clamped inside the wiring tube 7. The wiring tube 7 can make the connecting wire convenient to connect with the pressure gauge 10 through the box body 1, and the wiring tube 7 can be protected by the protective cover 8 to prevent debris from entering the interior. The outer surface of the pressure gauge 10 is fixedly connected with the original shock absorbing device 14, and the bottom surface of the original shock absorbing device 14 is fixedly connected to the inner bottom wall of the box body 1. The pressure gauge 10 can be shock-absorbing through the original shock absorbing device 14. The upper surface of each air spring shock absorber 12 is fixedly connected with a connecting block 15, and the upper surface of each connecting block 15 is fixedly connected to the bottom surface of the box body 1. The connecting block 15 can fix the air spring shock absorber 12 on the box body 1, so that the connection between the air spring shock absorber 12 and the box body 1 is more stable, thereby improving the stability of shock absorption.

[0032] Working principle: When in use, first, fix the original shock absorbing device 14 and the pressure gauge 10 inside the box 1, and move the box 1 to a suitable use position through the traction ring 6 and the mounting plate 5, and fix the box 1 through the sound insulation damping plate 13, and remove the protective cover 8 from the wiring tube 7, move the connecting wire through the wiring tube 7 to the inside of the box 1, and let the staff open the opening and closing door 4 through the handle 3, and connect the connecting wire to the pressure gauge 10;

[0033] When the pressure gauge 10 is connected, the pressure gauge 10 is turned on, and the opening and closing door 4 is closed again by the handle 3. When the equipment vibrates, the sound insulation damping plate 13 damps by its own material to reduce the transmission of vibration, and at the same time reduces the noise generated by the friction between the equipment, and reduces the vibration buffering by the air spring shock absorber 12, so that the box body 1 is less affected by the vibration. When the box body 1 is vibrated, the original shock absorbing device 14 can use its own structure to reduce the vibration again, and further reduce the vibration of the pressure gauge 10;

[0034] When the equipment is working, the sealing mechanism of the box body 1 can reduce the damage caused by wind and the like to the pressure gauge 10, and the noise generated by external vibration can be isolated by the isolation plate 11 in cooperation with the sound insulation cotton plate 9, so that the pressure gauge 10 can be protected. When the staff needs to observe the value of the pressure gauge 10, the operating data of the pressure gauge 10 can be directly observed through the perspective plate 2 for use.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
