[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. Pressure sensors are usually composed of a pressure-sensitive element and a signal processing unit. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. Pressure sensors are one of the most commonly used sensors in industrial practice. They are widely used in various industrial automation environments, involving many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, power, ships, machine tools, and pipelines.

[0003] A search revealed that Chinese patent CN212903655U discloses a high-precision pressure sensor, including a pressure sensor body. The bottom of the pressure sensor body is provided with a connecting heat-conducting column, and the bottom of the connecting heat-conducting column is provided with a heat-conducting sleeve. A heat dissipation component is threadedly connected to the outer wall of the connecting heat-conducting column. Currently, pressure sensors in the prior art still have some shortcomings in use. For example, traditional pressure sensors dissipate heat through the heat-conducting sleeve at the bottom, which has a limited heat dissipation surface and is not very effective. Secondly, the connection heat-conducting column on the heat-conducting sleeve is threaded onto the mounting shell, which is still not very convenient for disassembly and use. Utility Model Content

One end of the heat sink extends into the interior of the mounting shell, and the connecting seat is snapped into the heat sink by a fixing component.

[0008] The fixing assembly includes a mounting cavity, which is opened inside the connecting seat. A guide rod is fixedly installed on the inner side of the mounting cavity, and a spring is sleeved on the outer side of the guide rod. Adjacent guide rods in the mounting cavity are slidably connected by the same limiting plate. A limiting block is fixed on the outer side of the limiting plate.

[0017] Secondly, by inserting the heat sink of the pressure sensor body into the connector, during the insertion process, the sleeve on the heat sink is inserted into the slot and presses against the inclined part of the upper end of the limit block, so that the limit plate connected to the limit block slides on the guide rod of the mounting cavity and compresses the spring. When the sleeve hole of the sleeve corresponds to the position of the limit block, the spring returns to its original position and pushes the limit plate connected to the limit block into the sleeve to fix it. Combined with the push block on the limit plate, the pressure sensor body on the mounting shell can be quickly disassembled and assembled. Attached Figure Description

[0023] refer to Figures 1 to 4 The pressure sensor described in this embodiment is easy to install and includes a pressure sensor body 2 and a heat dissipation mechanism 1 at the lower end of the pressure sensor body 2. The pressure sensor is a known prior art product and will not be described in detail here.

[0024] The heat dissipation mechanism 1 includes a mounting shell 101. Ventilation holes 102 are symmetrically arranged on the outer side of the mounting shell 101. A ventilation mesh 103 is fixed inside one ventilation hole 102 of the mounting shell 101, and a fan 106 is fixed inside the other ventilation hole 102 of the mounting shell 101. A connecting seat 104 is fixed to the upper end of the mounting shell 101. A heat sink 105 is provided at the lower end of the pressure sensor body 2. A heat sink 107 is fixed to the lower end of the heat sink 105. The heat sink 105 is inserted into the inner side of the upper end of the connecting seat 104, and one end of the heat sink 107 extends into it. Inside the mounting housing 101, the connecting seat 104 is snapped into the heat sink 105 by the fixing component 3. By adding the heat sink 105 to the pressure sensor body 2, the heat sink 105 is installed at the connecting seat 104 on the mounting housing 101, so that the heat sink 107 at the lower end of the heat sink 105 can extend into the mounting housing 101. The heat sink 107 increases the heat dissipation area, and the cooling airflow generated by the fan 106 at the ventilation hole 102 of the mounting housing 101 passes through the passage of the adjacent heat sink 107, which can quickly remove the heat.

[0025] The fixing component 3 includes a mounting cavity 301, which is located within the connecting seat 104. A guide rod 304 is fixedly mounted inside the mounting cavity 301, and a spring 305 is sleeved on the outside of the guide rod 304. Adjacent guide rods 304 within the mounting cavity 301 are slidably mounted on the same limiting plate 302. A limiting block 306 is fixed on the outside of the limiting plate 302. A slot 307 is provided on the outside of the connecting seat 104. One end of the limiting block 306 extends into the slot 307 and engages with the heat sink 105. A push block 303 is fixed on the outside of the limiting plate 302, and one end of the push block 303 slides through the inner wall of the mounting cavity 301. By inserting the heat sink 105 of the pressure sensor body 2 into the connecting seat 104, the heat sink 105... The sleeve 10 is inserted into the slot 307 and presses against the inclined surface of the upper end of the limiting block 306, causing the limiting plate 302 connected to the limiting block 306 to slide on the guide rod 304 of the mounting cavity 301 and compress the spring 305. When the sleeve hole of the sleeve 10 corresponds to the position of the limiting block 306, the spring 305 resets and pushes the limiting plate 302 and the limiting block 306 into the sleeve 10 for fixation. When disassembling, it is only necessary to press the push blocks 303 on both sides of the connecting seat 104 at the same time, so that the push blocks 303 and the limiting plate 302 are close to each other. When the limiting block 306 on the limiting plate 302 is separated from the sleeve 10, the pressure sensor body 2 can be directly removed from the connecting seat 104, which facilitates subsequent disassembly and assembly.

[0026] refer to Figure 2 A fixing plate 4 is fixed to the lower end of the mounting shell 101. Fixing holes 5 are symmetrically opened on the inner side of the fixing plate 4. The mounting shell 101 can be easily installed and used through the fixing plate 4 with fixing holes 5 on the mounting shell 101.

[0027] refer to Figure 2 The upper end of the mounting shell 101 is provided with a through hole 6. One end of the heat sink 107 extends into the interior of the mounting shell 101 through the through hole 6. The lower end of the heat sink 107 can be easily extended into the mounting shell 101 through the through hole 6 on the mounting shell 101.

[0028] refer to Figure 4 A retaining sleeve 10 is symmetrically fixed on the outer side of the heat sink 105. The retaining sleeve 10 is inserted into the inner side of the slot 307. The limiting block 306 and the retaining sleeve 10 are snapped together. The retaining sleeve 10 on the heat sink 105 can be used to fix the limiting block 306 to the heat sink 105.

[0029] refer to Figure 3The mounting cavity 301 has symmetrically provided limiting grooves 8 on its inner side. The end of the limiting plate 302 slides in the limiting groove 8. When the push block 303 is squeezed through the limiting groove 8 in the mounting cavity 301, the limiting plate 302 slides in the limiting groove 8 and is limited. At this time, the limiting block 306 on the limiting plate 302 is separated from the sleeve 10, so that the pressure sensor body 2 can be quickly disassembled and used.

[0030] refer to Figure 3 The inner wall of the mounting cavity 301 is provided with a sliding hole 9. One end of the push block 303 slides through the sliding hole 9. Through the sliding hole 9 in the mounting cavity 301, the limiting plate 302 in the mounting cavity 301 can be easily operated by the push block 303.

[0031] refer to Figure 3 An assembly groove 7 is provided on the inner side of the mounting cavity 301. One end of the guide rod 304 is fixed to the inner side of the assembly groove 7. The compressed spring 305 can be conveniently stored through the assembly groove 7 in the mounting cavity 301.

[0032] Operating principle and advantages: During installation, the mounting housing 101 can be easily fixed by the fixing plate 4 with fixing holes 5 on the mounting housing 101. The heat sink 105 of the pressure sensor body 2 is inserted into the connecting seat 104. During insertion, the retaining sleeve 10 on the heat sink 105 is inserted into the slot 307, pressing against the inclined surface of the upper end of the limiting block 306. This causes the limiting plate 302 connected to the limiting block 306 to slide on the guide rod 304 of the mounting cavity 301. When the sleeve hole of the sleeve 10 corresponds to the position of the limiting block 306, the spring 305 is reset and pushes the limiting plate 302 to engage the limiting block 306 into the sleeve 10 for fixation. When disassembling, it is only necessary to simultaneously squeeze the push blocks 303 on both sides of the connecting seat 104 so that the push blocks 303 and the limiting plate 302 move closer to each other. When the limiting block 306 on the limiting plate 302 separates from the sleeve 10, the pressure sensor body 2 can be directly removed from the connecting seat 104.

[0033] During use, by adding a heat sink 105 to the pressure sensor body 2 and installing the heat sink 105 at the connecting seat 104 on the mounting shell 101, the heat sink 107 at the lower end of the heat sink 105 can extend into the mounting shell 101. The heat sink 107 increases the heat dissipation area, and the cooling airflow generated by the fan 106 at the ventilation hole 102 of the mounting shell 101 passes through the passage of the adjacent heat sink 107, which can quickly remove the heat.
