Description

Technical Field

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

[0002] A sensor is a detection device that can sense the information being measured and transform the sensed information into an electrical signal or other required form of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] When protecting temperature sensors, a protective housing is usually added to the outside of the sensor to achieve the purpose of pressure resistance. When the sensor is squeezed, the foreign object will make hard contact with the housing, resulting in poor buffering effect. At the same time, the protective housing is usually designed to open and close and is fixed by bolts, which makes it extremely inconvenient to maintain and replace the sensor and increases the workload. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a sensor with a pressure-resistant structure, which solves the problem that when the sensor is squeezed, the foreign object will make hard contact with the shell, resulting in poor buffering effect. At the same time, the protective shell is usually designed to open and close and is fixed by bolts, which makes it extremely inconvenient to maintain and replace the sensor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sensor with a pressure-resistant structure, comprising a sensor body, a lead wire installed at the bottom of the sensor body, a protective shell provided outside the sensor body, a pressure-resistant component installed outside the protective shell, and slide tracks respectively opened on both sides of the top of the sensor body, a positioning component installed in the slide track, the positioning component including a locking strip;

[0006] A spring is fixedly connected to one side of the locking strip, and the end of the spring is fixed to the inner wall of the slide. A handle is fixedly connected to the top of the locking strip. A sliding hole is opened at the top of the inner wall of the slide, and the handle is slidably connected in the sliding hole. A locking groove is opened on the inner wall of the protective shell corresponding to the position of the locking strip, and the locking strip is engaged in the locking groove.

[0007] As a further embodiment of this utility model: the side of the card strip away from the sensor body is designed to be inclined, and the shape of the card strip is adapted to the shape of the card slot.

[0008] As a further embodiment of this utility model: the sensor body is inserted into the protective shell, and the top and bottom of the protective shell are respectively provided with openings.

[0009] As a further embodiment of this utility model: the pressure-resistant component includes an elastic frame, and reinforcing ribs are fixedly connected to the four corners of the inner wall of the elastic frame. The ends of the reinforcing ribs are fixedly connected to the corners of the protective shell, and observation windows are provided on the front and rear sides of the elastic frame.

[0010] As a further embodiment of this utility model: the handle is L-shaped, and a pull ring is provided at the top of the handle.

[0011] As a further embodiment of this utility model: transparent partitions are provided on both sides of the inner wall of the protective shell, and the two transparent partitions are located on the front and rear sides of the sensor body, respectively, and a buffer cavity is provided between the inner wall of the protective shell and the transparent partitions.

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

[0013] 1. This sensor with a pressure-resistant structure allows it to slide through two handles in sliding holes. The handles then move two locking strips closer together and disengage from the grooves on the inner wall of the protective housing, releasing the lock between the protective housing and the sensor body. Lifting the handles allows the sensor body to be pulled out of the protective housing for easy removal. When installing the sensor body, it is inserted into the opening at the bottom of the protective housing, with the lead wire at the bottom of the sensor body passing through the bottom of the housing. As the sensor body slides into the housing, the two locking strips slide on both sides of the inner wall. When the sensor body stops moving, the spring force supports the locking strips, allowing them to engage with the grooves on the inner wall of the protective housing, thus locking the protective housing and the sensor body in place and completing the installation. Therefore, bolts are not required for assembling or disassembling the sensor body; the snap-fit ​​method facilitates maintenance or replacement, improving operational convenience.

[0014] 2. This sensor with a pressure-resistant structure resists external forces through pressure-resistant components on the outside of the protective shell. During the compression process, the elastic frame will deform. With the addition of multiple reinforcing ribs on the inner wall of the elastic frame, a certain support force is provided to the elastic frame. When the elastic frame is no longer under pressure, it can quickly return to its original shape. At the same time, after part of the force is transferred to the protective shell, the buffer cavity formed by the transparent partition and the inner wall of the protective shell can further weaken the generated force. Through multi-level buffering, the sensor body inside the protective shell is protected, thereby improving the pressure resistance of the sensor body. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1-6 As shown, this utility model provides a technical solution: a sensor with a pressure-resistant structure, including a sensor body 1, a lead wire 2 installed at the bottom of the sensor body 1, a protective shell 3 provided outside the sensor body 1, the sensor body 1 being inserted into the protective shell 3, and openings respectively at the top and bottom of the protective shell 3, a pressure-resistant component 4 installed outside the protective shell 3, the pressure-resistant component 4 including an elastic frame 401, reinforcing ribs 402 fixedly connected at the four corners of the inner wall of the elastic frame 401, the ends of the reinforcing ribs 402 being fixedly connected to the corners of the protective shell 3, and observation windows 403 provided on the front and rear sides of the elastic frame 401, which will deform during the process of being compressed, and with the setting of multiple reinforcing ribs 402 on the inner wall of the elastic frame 401, a certain supporting force is given to the elastic frame 401, and the elastic frame 401 can quickly return to its original shape when it is no longer compressed;

[0024] The top of the sensor body 1 has slides 6 on both sides, and a positioning component 5 is installed in the slides 6. The positioning component 5 includes a locking strip 501. The side of the locking strip 501 away from the sensor body 1 is inclined. The shape of the locking strip 501 is adapted to the shape of the slot 8. During the process of the sensor body 1 sliding into the protective shell 3, the two locking strips 501 slide on both sides of the inner wall of the protective shell 3. There is no need to manually adjust the position of the locking strip 501 to assist the sensor body 1 in inserting into the protective shell 3.

[0025] A spring 502 is fixedly connected to one side of the locking strip 501. The spring 502 supports the locking strip 501, allowing it to be locked into the slot 8 on the inner wall of the protective shell 3. This facilitates locking the protective shell 3 and the sensor body 1. The end of the spring 502 is fixed to the inner wall of the slide 6. A handle 503 is fixedly connected to the top of the locking strip 501. A sliding hole 7 is provided at the top of the inner wall of the slide 6. The handle 503 is slidably connected in the sliding hole 7. The handle 503 has an L-shaped design and a pull ring at the top. The pull ring facilitates pushing and pulling the handle 503 and also makes it easy to lift the sensor body 1.

[0026] The inner wall of the protective shell 3 has a slot 8 corresponding to the position of the clip 501, and the clip 501 is engaged in the slot 8.

[0027] Transparent partitions 9 are provided on both sides of the inner wall of the protective shell 3, and the two transparent partitions 9 are located on the front and rear sides of the sensor body 1 respectively. A buffer cavity 10 is provided between the inner wall of the protective shell 3 and the transparent partitions 9. When the protective shell 3 is subjected to force, the buffer cavity 10 formed by the transparent partitions 9 and the inner wall of the protective shell 3 can weaken the generated force and improve the protection effect on the sensor body 1.

[0028] The working principle of this utility model is as follows:

[0029] During the compression of the elastic frame 401, deformation occurs. Combined with the multiple reinforcing ribs 402 on the inner wall of the elastic frame 401, a certain supporting force is provided. When the elastic frame 401 is no longer compressed, it can quickly return to its original shape. After some of the force is transferred to the protective shell 3, the buffer cavity 10 can further weaken the generated force. When removing the sensor body 1, squeezing the two handles 503 causes them to slide in the sliding holes 7. The two handles 503 respectively drive the two locking strips 501 to move closer together and disengage from the locking grooves 8 on the inner wall of the protective shell 3, thus releasing the locking state between the protective shell 3 and the sensor body 1. Next, the upper... Lifting handle 503 allows the sensor body 1 to be pulled out from the protective housing 3, thus removing the sensor body 1. When installing the sensor body 1, insert it into the opening at the bottom of the protective housing 3. The lead wire 2 at the bottom of the sensor body 1 passes through the bottom of the protective housing 3. As the sensor body 1 slides into the protective housing 3, the two locking strips 501 slide on both sides of the inner wall of the protective housing 3. When the sensor body 1 stops moving, the spring force of the spring 502 supports the locking strips 501, allowing the locking strips 501 to engage in the slots 8 on the inner wall of the protective housing 3, thereby locking the protective housing 3 and the sensor body 1.
