Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a down-conducting hydraulic pressure sensor. Background Art

[0002] Hydraulic pressure sensor is the most commonly used pressure sensor in industrial practice. It is widely used in various industrial automatic control environments, involving many industries such as oil pipelines, water conservancy and hydropower, railway transportation, intelligent buildings, production automatic control, aerospace, military industry, petrochemicals, oil wells, electricity, ships, machine tools, pipeline air supply, boiler negative pressure, etc. Due to the wide range of use of hydraulic pressure sensors, it is also necessary to optimize the installation method of hydraulic pressure sensors.

[0003] For example, a hydraulic pressure sensor is disclosed in a Chinese utility model patent with announcement number CN212645961 U. Although the above-mentioned prior art reduces the influence of external vibration on the silicon piezoresistive sensitive element by setting a rubber ring on the side surface of the silicon piezoresistive sensitive element and improves the accuracy of sensor measurement, the use of the hydraulic pressure sensor is divided into long-term use and short-term installation use. The use of the hydraulic pressure sensor must be installed and fixed to avoid the shaking of the hydraulic pressure sensor and measurement errors during use. When it is only needed for a short installation and use for one or two measurements, such installation and fixation is more cumbersome, and the installation and fixation time may be longer than the measurement time, which increases the workload of the entire measurement and reduces the work efficiency. Therefore, it is necessary to design a hydraulic pressure sensor that can change the installation method according to the measurement needs. Utility Model Content

[0004] In order to solve the technical problem that a hydraulic pressure sensor is used briefly for simple measurement but the entire instrument needs to be installed and fixed, which affects the work efficiency, the utility model provides a downward-conducting hydraulic pressure sensor.

[0005] The utility model is implemented by the following technical scheme: a downward-conducting hydraulic pressure sensor, comprising a pressure sensor, a circuit being installed at one end of the pressure sensor, a supporting component being provided on the pressure sensor for supporting the pressure sensor during installation, a first fixing component being provided on the supporting component for temporarily fixing the position of the pressure sensor, and second fixing components being provided on both sides of the supporting component for permanently fixing the position of the pressure sensor.

[0006] Through the above technical solution, when the pressure sensor is needed for measurement, whether to use the first fixing component for fixing or the second fixing component for fixing is determined according to the required measurement time and number of times.

[0007] As a further improvement of the above solution, the support assembly includes a first support block arranged on one side of the pressure sensor and a second support block arranged on the other side of the pressure sensor, and a first rotating shaft rotatably mounted on one side of the first support block and rotatably mounted with the second support block.

[0008] Through the above technical solution, the first support block and the second support block clamp the pressure sensor to achieve a supporting effect.

[0009] As a further improvement of the above scheme, clamping grooves are provided on the opposite surfaces of the first support block and the second support block, and rubber plates are fixedly installed inside the two clamping grooves. The two rubber plates are arranged in a semicircular shape, and one side of the two rubber plates is in contact with the outer surface of the pressure sensor.

[0010] Through the above technical solution, the two rubber plates clamp the pressure sensor, thereby preventing the pressure sensor from sliding.

[0011] As a further improvement of the above solution, the first fixing component includes a first suction cup fixedly installed on one side of the first support block and a second suction cup fixedly installed on one side of the second support block, and magnets that cooperate with each other for adsorption are fixedly installed on one side of the first support block and the second support block.

[0012] Through the above technical solution, when only simple measurement or short-time measurement is needed, the pressure sensor can be simply installed and fixed by using the first suction cup and the second suction cup in conjunction with the magnet.

[0013] As a further improvement of the above scheme, the second fixing assembly includes a first frame arranged on one side of the first support block and having a first sliding groove, a second frame slidably installed inside the first frame through the first sliding groove and having a second sliding groove, and a fixing plate slidably installed inside the second frame through the second sliding groove, a replacement port connected to the second sliding groove is provided on one side of the second frame, and a second rotating shaft rotatably installed with the first support block is rotatably installed on one side of the first frame.

[0014] Through the above technical solution, when multiple measurements or long-term measurements are required, bolts are used to pass through the fixing plate for fixing, which not only prolongs the fixing time, but also allows the fixing angle to be adjusted according to different environmental angles, making it convenient to fix in different positions.

[0015] As a further improvement of the above solution, a fixed block is fixedly installed on one side of the first support block, a limiting belt is fixedly installed on one side of the fixed block, a limiting column is fixedly installed on one side of the second support block, a limiting ball is fixedly installed on one end of the limiting column, and a limiting hole matched with the limiting ball is opened on one side of the limiting belt.

[0016] Through the above technical solution, after the first supporting block and the second supporting block clamp the pressure sensor, if long-term measurement is required, a limiting belt can be used in conjunction with a limiting ball for long-term and stable fixation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a support component, a first fixing component and a second fixing component. The support component clamps the hydraulic pressure sensor. According to the number of measurements or time required, it is determined whether the first fixing component or the second fixing component needs to be used for fixing. The first fixing component can fix the support component in a short time and is installed very quickly. The second fixing component can fix the support component for a long time and can adjust the fixing angle according to different needs. The second fixing component needs bolts for fixing and installation so it is slightly slower than the first fixing component. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Combination Figure 1-Figure 3 The support assembly includes a first support block 201 arranged on one side of the pressure sensor 1 and a second support block 202 arranged on the other side of the pressure sensor 1. A first rotating shaft 5 rotatably mounted with the second support block 202 is rotatably mounted on one side of the first support block 201. Clamping grooves are provided on the opposite surfaces of the first support block 201 and the second support block 202. Rubber plates 6 are fixedly mounted inside the two clamping grooves. The two rubber plates 6 are both arranged in a semicircular ring shape. One side of the two rubber plates 6 is in contact with the outer surface of the pressure sensor 1. The two rubber plates 6 clamp the pressure sensor 1 to prevent the pressure sensor 1 from sliding.

[0027] Combination Figure 2 The first fixing component includes a first suction cup 301 fixedly installed on one side of the first support block 201 and a second suction cup 302 fixedly installed on one side of the second support block 202. One side of the first support block 201 and the second support block 202 are fixedly installed with magnets 7 that cooperate with each other for adsorption. When only simple measurements or short-term measurements are required, the pressure sensor 1 can be simply installed and fixed using the first suction cup 301 and the second suction cup 302 in conjunction with the magnet 7.

[0028] Combination Figure 1-Figure 3 The second fixing component includes a first frame 401 which is arranged on one side of the first supporting block 201 and has a first sliding groove, a second frame 402 which is slidably installed inside the first frame 401 through the first sliding groove and has a second sliding groove, and a fixing plate 403 which is slidably installed inside the second frame 402 through the second sliding groove, a replacement port which is connected to the second sliding groove is provided on one side of the second frame 402, a second rotating shaft 8 which is rotatably installed with the first supporting block 201 is rotatably installed on one side of the first frame 401, a fixing block is fixedly installed on one side of the first supporting block 201, a limiting belt 9 is fixedly installed on one side of the fixing block, a limiting column is fixedly installed on one side of the second supporting block 202, a limiting ball 10 is fixedly installed on one end of the limiting column, and a limiting hole which is compatible with the limiting ball 10 is provided on one side of the limiting belt 9. When multiple measurements or long-term measurements are required, bolts are used to pass through the fixing plate 403 for fixing, which can not only prolong the fixing time, but also adjust the fixing angle according to different environmental angles, so as to facilitate fixing at different positions.

[0029] The implementation principle of a down-conducting hydraulic pressure sensor in the embodiment of the present application is as follows: when the down-conducting hydraulic pressure sensor 1 is needed for measurement, the installation and fixing method is determined according to the time or number of measurements required, and the pressure sensor 1 is clamped by the first support block 201 and the second support block 202 in cooperation with the rubber plate 6. When the measurement is short-term or the number of measurements is very small, the first suction cup 301 and the second suction cup 302 are used to suck the object, and the two magnets 7 are attracted to each other to simply fix the pressure sensor 1. When the measurement is long-term or the number of measurements is very large, the second rotating shaft 8 is rotated to The first frame 401 is rotated and adjusted to a suitable installation angle. After sliding the second frame 402 and the fixing plate 403 to determine the fixing position, nails or bolts are used on one side of the fixing plate 403 to pass through the parts that can be used to fix the fixing plate 403, and then the limiting belt 9 is used in conjunction with the limiting ball 10. The pressure sensor 1 can be fixed for a long time. When the pressure sensor 1 needs to be disassembled, the fixing plate 403 can be replaced through the replacement port. This setting can not only change the fixing method according to the use requirements of the pressure sensor 1, but also greatly improve the installation speed and improve work efficiency.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
