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] A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate pressure higher than the ambient pressure. It is widely used in almost all industrial processes and scientific research fields. It can be seen everywhere in thermal pipelines, oil and gas transmission, water and gas supply systems, vehicle repair and maintenance shops, etc., especially in industrial process control and technical measurement.

[0003] Most of the pressure gauges on the market now use damping fluid or buffer devices for shock absorption. The shock absorption method when applied is relatively simple. When dealing with a smaller degree of vibration force, the vibration force can be offset. However, when dealing with a larger degree of vibration, a part of the vibration force will still affect the pressure gauge itself, and the shock absorption effect is not good. The pressure gauge will shake violently with the vibration of the main equipment, causing the pressure gauge pointer to swing violently and damage the pointer; the violent swing of the pressure gauge is likely to cause the joint to loosen, and then cause a leakage accident. Being in a bumpy working environment for a long time is likely to reduce the service life of the pressure gauge. Therefore, the present application aims to provide a shock-absorbing pressure gauge, which can increase the shock absorption effect of the pressure gauge, ensure the normal use of the pressure gauge, and extend the service life of the pressure gauge body. Utility Model Content

It should also be understood that in the context, when it is mentioned that an element or feature is connected to another element (one or more), it can not only be directly connected to the other (one or more) elements, but also indirectly connected to the other (one or more) elements through an intermediate element.

[0036] The utility model provides a shock-absorbing pressure gauge, comprising a buffer tube 1, a shock-absorbing box 3, a pressure gauge body 5 and an instrument bracket 6. The buffer tube 1 has a curved portion and is connected to a delivery pipeline 2, a connecting tube 4 connected to the buffer tube 1 is provided in the shock-absorbing box 3, the pressure gauge body 5 is connected to the connecting tube 4, the shock-absorbing box 3 is fixed to the bottom of a top platform 62 of the instrument bracket 6, the top of the connecting tube 4 is arranged on the top platform 62 of the instrument bracket 6 through a tripod 7, and movable plates 31 are arranged on both sides of the inner cavity of the shock-absorbing box 3, the side of the movable plate 31 close to the inner wall of the shock-absorbing box 3 is connected to the inner wall of the shock-absorbing box 3 through a shock-absorbing spring 32, and the side of the movable plate 31 away from the inner wall of the shock-absorbing box 3 is in contact with the connecting tube 4.

[0037] When the pressure gauge adopts the above structure, when it is subjected to external vibration, the buffer tube 1 with a curved portion is first used to buffer the vibration to achieve a primary buffering effect; then, the vibration received by the connecting tube 4 is weakened and dispersed to the shock absorbing box 3 through the movable plate 31 abutting against it through the buffer spring 71 to achieve a secondary weakening effect; finally, the top end of the connecting tube 4 can be stably fixed to the top platform 62 of the instrument bracket 6 through the tripod 7 to achieve a tertiary fixing effect. For further information, please refer to Figure 2 The tripod 7 is provided with a buffer spring 71 on the periphery, which can attenuate the force between the top of the connecting pipe 4 and the top platform 62 of the instrument bracket 6. The above structure not only realizes the fixed installation of the pressure gauge body 5, but also increases the shockproof effect and impact resistance of the pressure gauge body 5, making it durable, ensuring the normal use of the pressure gauge body 5, ensuring the detection accuracy of the pressure gauge body 5, and extending the service life of the pressure gauge body 5.

[0038] In some embodiments, the buffer tube 1 includes at least two curved portions to allow the buffer tube 1 to deform to reduce shock. Figure 1 The buffer tube 1 is designed to be S-shaped and have three bends, so that the shock wave starts to be buffered when it passes through the bends, and the elastic deformation of the buffer tube 1 itself is used to further buffer the vibration, so as to achieve a primary buffering effect. It should be noted that the utility model does not limit the specific form of the bend of the buffer tube. For example, the buffer tube can be made into an S shape to form a bend, or the buffer tube can be coiled to form a bend.

[0039] In some embodiments, the number of groups of shock absorbing springs 32 on both sides of the inner cavity of the shock absorbing box 3 is the same. Figure 1 In this embodiment, two groups of shock absorbing springs 32 are respectively provided on both sides of the inner cavity of the shock absorbing box 3. One end of the shock absorbing spring 32 is connected to the inner wall of the shock absorbing box 3, and the other end is connected to the movable plate 31 provided in the inner cavity of the shock absorbing box 3. When the lower part of the connecting pipe 4 is vibrated, the movable plate 31 abutting against the connecting pipe 4 weakens and disperses the shock wave to the shock absorbing box 3 through the shock absorbing spring 32. The number of groups of shock absorbing springs 32 on both sides of the shock absorbing box 3 is consistent to ensure that the force inside the shock absorbing box 3 is uniform and to avoid the failure of the shock absorbing box 3 due to uneven force. Furthermore, the shock absorbing box 3 is located at the lower part of the connecting pipe 4 so that the secondary shock absorption can be carried out in time when the connecting pipe 4 is vibrated. It should be noted that the utility model does not specifically limit the number of groups of shock absorbing springs 32 on each side of the shock absorbing box 3, and it is only necessary to meet the requirement that the number of groups of shock absorbing springs 32 on both sides of the shock absorbing box 3 is consistent.

[0040] In some embodiments, the top platform 62 of the instrument bracket is provided with a first through hole (not shown in the figure), and the top of the shock absorbing box 3 is provided with a second through hole (not shown in the figure). The connecting tube 4 extends from the first through hole to be connected to the pressure gauge body 5, and the connecting tube 4 extends from the second through hole to be connected to the buffer tube 1. In addition, the pressure gauge body 5 is fixed to the top platform 62 of the instrument bracket 6 by a U-shaped clip (not shown in the figure), that is, in the present utility model, the U-shaped clip is used to fix the pressure gauge body 5, and the tripod 7 is used to fix the top of the connecting tube 4. The use of such a structure can make the shock absorbing pressure gauge have good stability as a whole, so as to achieve the three-level fixing effect of the shock absorbing pressure gauge. It should be noted that, please refer to Figure 1 The instrument bracket 6 also includes two side vertical rods 61, and the bottom ends of the two side vertical rods 61 are used to be fixed on the ground or other installation platforms to achieve the installation and fixation of the shock-absorbing pressure gauge as a whole.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
