Description

Technical Field

[0001] This utility model belongs to the field of pressure sensor technology, specifically a pressure sensor with a protection mechanism. Background Technology

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable electrical signals according to certain rules. A pressure sensor typically consists of a pressure-receiving element, a converter, an amplifier, and an output device.

[0003] Pressure sensors are widely used in industrial automation environments in many industries such as water conservancy and hydropower, railway transportation, intelligent buildings, and aerospace. After the pressure sensor is used, the pressure block of the sensor needs to be protected. However, the existing pressure sensors do not have a protective mechanism on their outer surface, which means that the pressure block is exposed to the outside world when not in use. This makes the pressure block easy to be damaged, resulting in a decrease in the accuracy of the sensor data. Therefore, it is necessary to improve it. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a pressure sensor with a protective mechanism, which has the advantage of protecting the pressure block.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure sensor with a protection mechanism, comprising a sensor body, a pressure-bearing block body fixedly mounted on the top of the sensor body, a ring movably sleeved on the outer surface of the sensor body, limit plates fixedly mounted on the left and right sides of the top of the ring, a circular shaft movably sleeved between the limit plates, an mounting block fixedly sleeved on the outer surface of the circular shaft, a first protective plate fixedly mounted on the bottom of the mounting block, limit grooves formed at both the front and rear ends of the first protective plate, a limit block movably mounted on the top of the inner surface of the limit groove, a second protective plate fixedly connected between the limit blocks, and two second protective plates, the outer surfaces of the two second protective plates being movably connected to the inner surface of the first protective plate, and a first magnet and a second magnet respectively fixedly mounted inside the bottom ends of the two second protective plates.

[0006] As a preferred embodiment of this invention, a circuit is fixedly installed on the back of the sensor body, a fixing block is fixedly installed on the outer surface of the sensor body, and an L-shaped block is fixedly installed on the bottom of the ring, with the inner surface of the L-shaped block being movably connected to the outer surface of the fixing block.

[0007] As a preferred embodiment of this invention, a fixing ring is fixedly sleeved on the bottom of the outer surface of the sensor body, and a spring is fixedly installed on the top of the fixing ring.

[0008] As a preferred embodiment of this invention, a push plate is fixedly mounted on the top of the spring, and the top of the push plate is movably connected to the bottom of the ring.

[0009] As a preferred embodiment of the present invention, the outer surface of the fixing ring is provided with a sliding groove, and a slider is movably installed inside the sliding groove.

[0010] As a preferred embodiment of this invention, a vertical rod is fixedly installed on the top of the slider, and a limit ring is fixedly sleeved on the top of the outer surface of the vertical rod.

[0011] As a preferred embodiment of this invention, a connecting block is movably sleeved on the outer surface of the vertical rod, and the rear end of the connecting block is fixedly connected to the outer surface of the ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a first protective plate, a second protective plate, a first magnet, and a second magnet, allows the operator to protect the pressure block body when needed. First, by rotating the ring, the L-shaped block disengages from the fixed block, allowing the ring to move upward. This causes the ring to lift the first protective plate. Then, by rotating the first protective plate to a horizontal position, the operator pulls out the second protective plate inside the first protective plate, bringing the two second protective plates into contact. This causes the first magnet and the second magnet to come into contact, and under the action of magnetic force, the first magnet and the second magnet will attract each other, thus protecting the pressure block body and preventing damage to the pressure block body when not in use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5 As shown, this utility model provides a pressure sensor with a protective mechanism, including a sensor body 1. A pressure-bearing block body 2 is fixedly installed on the top of the sensor body 1. A ring 3 is movably sleeved on the outer surface of the sensor body 1. Limiting plates 4 are fixedly installed on the left and right sides of the top of the ring 3. A circular shaft 5 is movably sleeved between the limiting plates 4. An installation block 6 is fixedly sleeved on the outer surface of the circular shaft 5. A first protective plate 7 is fixedly installed on the bottom of the installation block 6. Limiting grooves 8 are opened at both the front and rear ends of the first protective plate 7. Limiting blocks 9 are movably installed on the top of the inner surface of the limiting grooves 8. A second protective plate 10 is fixedly connected between the limiting blocks 9. There are two second protective plates 10. The outer surface of the protective plate 10 is movably connected to the inner surface of the first protective plate 7. The bottom ends of the two second protective plates 10 are respectively fixedly installed with a first magnet 11 and a second magnet 12. By moving the ring 3 upward and then rotating the first protective plate 7 to make it horizontal, and then pulling the second protective plate 10 outward, the first magnet 11 and the second magnet 12 will come into contact. Since the magnetic poles of the first magnet 11 and the second magnet 12 are opposite, the first magnet 11 and the second magnet 12 can be attracted together under the action of magnetic force, thereby protecting the pressure block body 2 and preventing damage to the pressure block body 2 when it is not in use.

[0022] The sensor body 1 has a circuit 13 fixedly installed on its back side, a fixing block 14 fixedly installed on its outer surface, and an L-shaped block 15 fixedly installed on the bottom of the ring 3. The inner surface of the L-shaped block 15 is movably connected to the outer surface of the fixing block 14. By setting the L-shaped block 15, when the L-shaped block 15 is engaged with the fixing block 14, it will fix the ring 3, thereby releasing the protection of the pressure block body 2.

[0023] Among them, a fixing ring 16 is fixedly sleeved on the bottom of the outer surface of the sensor body 1, and a spring 17 is fixedly installed on the top of the fixing ring 16; by setting the fixing ring 16, the spring 17 can be stably installed on the top of the fixing ring 16, and the spring 17 is in a compressed state.

[0024] Among them, a push plate 18 is fixedly installed on the top of the spring 17, and the top of the push plate 18 is movably connected to the bottom of the ring 3. When the ring 3 is released from its fixed position, the spring 17 can push the push plate 18 upward under the elastic recovery action, thereby causing the push plate 18 to push the ring 3 upward.

[0025] The outer surface of the fixed ring 16 is provided with a groove 19, and a slider 20 is movably installed inside the groove 19. By setting the groove 19, the groove 19 can limit the slider 20, so that the slider 20 can move along the inner surface of the groove 19.

[0026] The top of the slider 20 is fixedly mounted with a vertical rod 21, and a limit ring 23 is fixedly sleeved on the top of the outer surface of the vertical rod 21. When the vertical rod 21 moves, it will drive the slider 20 to move along the inner surface of the slide groove 19. The top of the limit ring 23 is at the same height as the top of the sensor body 1.

[0027] The vertical rod 21 has a connecting block 22 movably sleeved on its outer surface, and the rear end of the connecting block 22 is fixedly connected to the outer surface of the ring 3. When the ring 3 rises, it will drive the connecting block 22 to move upward along the outer surface of the vertical rod 21. The limiting ring 23 can prevent the connecting block 22 from detaching from the outer surface of the vertical rod 21, thereby limiting the ring 3 and preventing the ring 3 from detaching from the outer surface of the sensor body 1.

[0028] Working principle and usage process of this utility model:

[0029] When the operator needs to protect the pressure block body 2, firstly, by rotating the ring 3, the ring 3 causes the L-shaped block 15 to rotate, thereby disengaging the L-shaped block 15 from the fixed block 14. At this time, the spring 17 will push the push plate 18 upward under the elastic recovery action, which in turn causes the ring 3 to move upward, thereby causing the ring 3 to drive the connecting block 22 to move upward on the outer surface of the vertical rod 21. Under the obstruction of the limiting ring 23, the movement range of the connecting block 22 can be limited, thereby preventing the ring 3 from moving upward and disengaging from the outer surface of the sensor body 1. Then, the operator rotates the first protective plate 7 and pulls the second protective plate 10 out from the inside of the first protective plate 7, so that the two second protective plates 10 come into contact together. At this time, the first magnet 11 and the second magnet 12 will be attracted together under the action of magnetic force, thereby protecting the pressure block body 2 and preventing damage to the pressure block body 2.
