Description

Technical Field

[0001] This utility model relates to the field of pressure measuring instrument technology, specifically to a shock-resistant pressure gauge with remote transmission function. Background Technology

[0002] Vibration-resistant pressure gauges (also known as shock-resistant pressure gauges) are specialized instruments designed for complex working conditions such as vibration, shock, and pulsating pressure in the field of industrial pressure measurement. Their core is to solve the pain points of decreased measurement accuracy, pointer jitter, and easy damage of components under vibration environment by optimizing the structure and protective design on the basis of ordinary pressure gauges, so as to ensure stable and reliable pressure data.

[0003] In the drilling operations of petroleum, coal, and geological sectors, anti-vibration pressure gauges are essential for measuring high-viscosity media. However, commonly used anti-vibration pressure gauges have a drawback: they require personnel to be on-site to observe the oil pressure at close range, which is inconvenient and makes it difficult to observe data from multiple pressure gauges simultaneously. Therefore, to address these issues, an anti-vibration pressure gauge with remote transmission function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a shock-resistant pressure gauge with remote transmission function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A shock-resistant pressure gauge with remote transmission function includes a hexagonal connector assembly and a housing assembly. The housing assembly is fixedly connected to the top of the hexagonal connector assembly. A protective cover is provided on the inner side of the hexagonal connector assembly. A sealing gasket located on the outer side of the protective cover is fixedly connected to the inner side of the hexagonal connector assembly. A damping assembly located on the inner side of the hexagonal connector assembly is provided at the top of the sealing gasket and the protective cover. A sealing gasket is fixedly connected to the top of the damping assembly. A diaphragm is fixedly connected to the top of the sealing gasket. A push rod penetrating the diaphragm is fixedly connected to the top of the sealing gasket. A fork spring is provided at the top of the push rod. A transmission mechanism located on the inner side of the housing assembly is provided at the top of the fork spring. A sensor bracket is fixedly connected to the rear side of the transmission mechanism. A magnetic head located inside the sensor bracket is provided on the rear side of the transmission mechanism. An angle sensor is fixedly connected to the side of the sensor bracket away from the transmission mechanism. A dial assembly is provided on the front side of the transmission mechanism. A pointer assembly penetrating the dial assembly is fixedly connected to the front side of the transmission mechanism. An aviation scale is fixedly connected to the outer side of the housing assembly.

[0006] Preferably, the outer diameter of the sealing gasket matches the inner diameter of the hexagonal connector assembly, and the inner diameter of the sealing gasket matches the outer diameter of the cover.

[0007] Preferably, the shape of the sealing gasket matches the shape of the diaphragm, both being disc-shaped, and the diameter of the sealing gasket matches the diameter of the diaphragm.

[0008] Preferably, the dial assembly is disc-shaped, and the diameter of the dial assembly is larger than the diameter of the protective glass portion of the outer casing assembly.

[0009] Preferably, the push rod and the fork spring are connected by a hexagonal thread and a spring washer, with the push rod located directly below the fork spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, through the setting of transmission mechanism, sensor bracket, magnetic head, angle sensor, dial assembly, pointer assembly and aviation scale, etc., the angle sensor is installed at the rear end of the mechanism assembly, and the magnetic head is installed at the rear end of the central gear shaft. The magnetic head drives the internal chip of the angle sensor, and after processing by the internal motherboard of the angle sensor, it outputs a current signal. The voltage input is 12-24VDC. The internal mechanism drives the angle sensor and transmits it to the digital display meter or data terminal through the data cable. It can also be transmitted wirelessly to the computer and mobile phone to directly observe the real-time pressure. The data of multiple anti-vibration pressure gauges can be viewed on one screen at the same time. This solves the problem that anti-vibration pressure gauges are essential for measuring high viscosity media in the drilling equipment operation of petroleum, coal, geology and other departments. However, the commonly used anti-vibration pressure gauges have a disadvantage: the staff needs to observe the oil pressure at close range on site, which is inconvenient to use and makes it difficult to observe the data of multiple pressure gauges at the same time. 2. In this utility model, through the damping components, diaphragm, push rod and fork spring, the damping mechanism inside the instrument controls the pulsation throughout the entire pressure range. No adjustment is required during use. This structure can not only measure the pressure of violent pulsation, but also withstand instantaneous pressure shocks (such as sudden pressure relief). The diaphragm, push rod and fork spring can ensure "precise force transmission", further ensuring the accuracy of measurement. Attached Figure Description

[0016] Please see Figure 1-2 This utility model provides a technical solution: A shock-resistant pressure gauge with remote transmission function includes a hexagonal connector assembly 1 and a housing assembly 2. The housing assembly 2 is fixedly connected to the top of the hexagonal connector assembly 1. A cover 3 is provided on the inner side of the hexagonal connector assembly 1. A sealing gasket 4 located outside the cover 3 is fixedly connected to the inner side of the hexagonal connector assembly 1.

A sealing gasket 6 is fixedly connected to the top of the damping assembly 5. A diaphragm 7 is fixedly connected to the top of the sealing gasket 6. A push rod 8 penetrating the diaphragm 7 is fixedly connected to the top of the sealing gasket 6. A fork spring 9 is provided at the top of the rod 8. A transmission mechanism 10 is provided at the top of the fork spring 9 and located inside the housing assembly 2. A sensor bracket 11 is fixedly connected to the rear side of the transmission mechanism 10. A magnetic head 12 is provided inside the sensor bracket 11 and located at the rear side of the transmission mechanism 10. An angle sensor 13 is fixedly connected to the side of the sensor bracket 11 away from the transmission mechanism 10. A dial assembly 14 is provided at the front side of the transmission mechanism 10. A pointer assembly 15 is fixedly connected to the front side of the transmission mechanism 10 and located through the dial assembly 14. An aviation connector 16 is fixedly connected to the outer side of the housing assembly 2.

[0017] The outer diameter of the sealing gasket 4 matches the inner diameter of the hexagonal connector assembly 1, and the inner diameter of the sealing gasket 4 matches the outer diameter of the cover 3, which can effectively ensure the sealing effect inside the pressure gauge; the shape of the sealing gasket 6 matches the shape of the diaphragm 7, both being disc-shaped, and the diameter of the sealing gasket 6 matches the diameter of the diaphragm 7, which can effectively improve the sealing effect at the diaphragm 7 and ensure the stability of pressure sensing and transmission of the diaphragm 7; the dial assembly 14 is disc-shaped, and the diameter of the dial assembly 14 is larger than the diameter of the protective glass part of the outer shell assembly 2, which can effectively ensure the viewing effect of the dial assembly 14 and avoid the phenomenon of bottom leakage; the push rod 8 and the fork spring 9 are connected by hexagonal threads and spring washers, and the push rod 8 is located directly below the fork spring 9, further ensuring the stability of pressure transmission.

[0018] Workflow: When a shock-resistant pressure gauge with remote transmission function is required, the entire system is powered externally. The measuring medium presses against the inner cover 3 of the hexagonal connector assembly 1 and transmits the signal to the damping assembly 5. The damping assembly 5 lifts the diaphragm 7 and the push rod 8, and the push rod 8 lifts the fork spring 9. At this time, the fork spring 9 deforms under force, causing the transmission mechanism 10 to move. Then, the transmission mechanism 10 drives the magnetic head 12 to rotate. The rotation of the magnetic head 12 causes the internal chip of the angle sensor 13 to work and output a 4-20mA current signal. The current signal is input to an external digital display, wireless transmission module, or data terminal through the aviation connector 16 and data cable. Data from multiple shock-resistant pressure gauges can then be easily viewed from a distance, making it more convenient.
