Description

Technical Field

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

[0002] A pressure gauge is an instrument used to measure pressure, primarily for measuring the pressure of liquids, gases, and steam. Its operating principle is to utilize an elastically sensitive element (such as a spring tube) to produce elastic deformation under the action of pressure and vacuum. The magnitude of this deformation is linearly related to the applied pressure, which is amplified by a transmission mechanism, and the measured pressure is indicated by a pointer on a graduated dial. When in use, a pressure gauge is generally directly threaded onto a pipe via its bottom. Since the pressure gauge is directly connected to the pipe during use, when the fluid flows within the pipe, the pipe vibrates, and this vibration is transmitted to the pressure gauge. Prolonged exposure to vibration can easily cause components within the pressure gauge to fall off, resulting in inaccurate pressure detection and a reduced service life of the pressure gauge.

[0003] For example, Chinese patent publication number CN219200525U discloses a seismic-resistant digital pressure gauge, comprising: a main unit, comprising a pressure gauge body, the bottom of the pressure gauge body being fixedly connected to a vertical pipe; a seismic-resistant unit, comprising a plurality of curved plates, the curved plates being fixedly connected to a Y-shaped rod, the vertical pipe being fixedly connected to a rectangular plate, the rectangular plates being symmetrically provided with rectangular grooves, the left and right inner side walls of the rectangular groove being symmetrically fixedly connected to round rods, the inner side wall of the rectangular groove being fixedly connected to a first spring, the first spring being sleeved on the round rod, a connecting assembly being provided between the first spring and the Y-shaped rod, and a shock-absorbing assembly being provided in the rectangular groove.

[0004] The aforementioned utility model utilizes the up-and-down movement of the Y-shaped rod, which drives the fixed plate up-and-down, which in turn drives the rotating rod to rotate, causing the circular plate to move left and right, compressing the first spring. This first spring provides a buffering effect, reducing vibration damage to the pressure gauge body and extending the device's service life. However, during use, its vertical shock resistance is poor, affecting the seismic pressure gauge's ability to detect pipeline pressure. Furthermore, the lack of physical protection and anti-collision mechanisms makes it susceptible to damage. Utility Model Content

The upper protective seat 2 and the lower protective seat 3 are movably connected through a buffer spring 23, and the lower protective seat 3 is slidably connected to the connecting seat 4. An anti-seismic component 8 is provided between the lower protective seat 3 and the connecting seat 4.

[0032] like Figure 1-4 As shown, in this embodiment, the upper protective seat 2 and the lower protective seat 3 are corresponding arc-shaped structures, and an arc-shaped groove 21 corresponding to the meter head 1 is provided on the opposite side of the upper protective seat 2 and the lower protective seat 3, so that the meter head 1 can be set between the upper protective seat 2 and the lower protective seat 3, and connecting grooves 22 are provided at both ends of the upper protective seat 2 and the lower protective seat 3. The two ends of the buffer spring 23 are respectively fixedly connected to the groove walls of the connecting grooves 22 of the upper protective seat 2 and the lower protective seat 3 located on the same side. By setting the buffer spring 23, on the one hand, the connection between the upper protective seat 2 and the lower protective seat 3 can be realized. On the other hand, when subjected to external impact or extrusion, the buffer spring 23 can be used to buffer the pressure to avoid damage to the meter head 1 set between the upper protective seat 2 and the lower protective seat 3.

When the pressure gauge is subjected to longitudinal pressure, the mounting tube 6 moves downward in the sliding groove 41, so that the first connecting spring 61 is compressed. By providing the first connecting spring 61, the longitudinal pressure on the pressure gauge can be buffered, thereby improving the anti-seismic effect.

[0036] like Figure 1-4 As shown, in this embodiment, a second connecting spring 62 is provided in the mounting tube 6, and the two ends of the second connecting spring 62 are fixedly connected to the bottom of the vertical pipe 5 and the top of the connecting seat 4 respectively.

The deformation of the second connecting spring 62 is used to buffer the longitudinal tension of the pressure gauge. At the same time, the pressure gauge drives the upper protective seat 2 to move upward relative to the lower protective seat 3, and the buffer spring 23 is deformed. While buffering the force, it prevents the upper protective seat 2 from separating from the lower protective seat 3 and causing damage to the gauge head 1.

The two ends of the buffer spring 23 are respectively fixedly connected to the groove wall of the connecting groove 22 of the upper protective seat 2 and the lower protective seat 3 on the same side. By setting the buffer spring 23, on the one hand, the connection between the upper protective seat 2 and the lower protective seat 3 can be realized, and on the other hand, when it is subjected to external When the pressure gauge is subjected to impact or extrusion, the buffer spring 23 can be used to buffer the pressure to avoid damage to the gauge head 1 arranged between the upper protective seat 2 and the lower protective seat 3; when the pressure gauge is subjected to longitudinal pressure, the mounting tube 6 moves downward in the sliding groove 43, driving the limit plate 61 to move downward, so that the first connecting spring 61 is compressed. By setting the first connecting spring 61, the longitudinal pressure on the pressure gauge can be buffered. When the pressure gauge is subjected to longitudinal tension, the riser 5 moves upward in the mounting tube 6, and the second connecting spring 62 is stretched. The deformation of the second connecting spring 62 is used to buffer the longitudinal tension on the pressure gauge. At the same time, the pressure gauge drives the upper protective seat 2 to move upward relative to the lower protective seat 3, and the buffer spring 23 is deformed, which buffers the force while preventing the upper protective seat 2 from separating from the lower protective seat 3 and damaging the gauge head 1.

When the first slider 81 and the second slider 82 slide, the shock-absorbing spring 84 is deformed to buffer the longitudinal force. When the pressure gauge is subjected to a lateral force, the second slider 82 moves up and down in the second slide groove 86. When the second slider 82 moves, it drives the rotating rod 83 to rotate. When the rotating rod 83 rotates, it drives the first slider 81 to slide. When the first slider 81 and the second slider 82 slide, the shock-absorbing spring 84 is deformed to buffer the lateral force. By providing the anti-seismic component 8 and utilizing the elastic deformation of the shock-absorbing spring 84, a buffering effect is achieved, the damage caused by vibration to the pressure gauge is reduced, and the service life of the device is extended.
