Description

Technical Field

[0001] This utility model belongs to the technical field of platinum resistance thermometers, specifically relating to a shockproof platinum resistance thermometer. Background Technology

[0002] Resistance thermometers, also known as resistance temperature detectors (RTDs), are temperature sensors made using materials whose resistance changes with temperature. Because they are almost invariably made of platinum, they are commonly called platinum resistance thermometers. Platinum resistance thermometers utilize the functional relationship between their resistance and temperature, and due to their high accuracy, wide measurement range, good repeatability, and stability, they are widely used for temperature measurement in the medium temperature range (-200℃ to 650℃).

[0003] In practical applications, platinum resistance thermometers are small in size and easy to carry. However, they lack a structure to protect the thermometer core during transport, making them susceptible to external impacts or vibrations, which can lead to measurement errors or even damage to the thermometer.

[0004] Therefore, a shockproof platinum resistance thermometer is needed to solve the problem that the existing technology lacks a structure to protect the thermometer core, making it susceptible to external impacts or vibrations, which can lead to measurement errors or even damage to the thermometer.

[0011] Furthermore, it should be noted that one side of the mounting block has an inclined surface that matches the angle of the positioning block, and the interior of the mounting block has a positioning hole that matches the size of the positioning block.

[0012] In a preferred embodiment, the shock-absorbing mechanism consists of a first fixed block, a rotating rod, a second fixed block, a clamping plate, a buffer spring, and a buffer layer.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-4 This utility model provides a shockproof platinum resistance thermometer, including a platinum resistance thermometer body 1, a protective sleeve 2, a connecting mechanism 3 and a shockproof mechanism 4. The protective sleeve 2 is disposed outside the thermal resistor below the platinum resistance thermometer body 1 through the connecting mechanism 3, and the shockproof mechanism 4 is disposed between the protective sleeve 2 and the thermal resistor.

[0026] The protective sleeve 2 is composed of an upper cylinder 201, a threaded groove 202, a lower cylinder 203, a movable ring 204, a rotating ring 205, and a mounting block 206. The bottom surface of the upper cylinder 201 is provided with a threaded groove 202. The movable ring 204 is fixedly connected to the upper part of the lower cylinder 203. The rotating ring 205 is fixedly connected to the upper part of the upper cylinder 201. The mounting blocks 206 are symmetrically fixedly connected to the left and right sides of the upper cylinder 201.

[0027] The connecting mechanism 3 consists of a fixed ring 301, a connecting block 302, a positioning block 304, a baffle 305, and a limiting spring 306. The fixed ring 301 is fixedly connected to the outside of the thermal resistor above the platinum resistance thermometer body 1, and the bottom surface of the fixed ring 301 is provided with an annular groove for the rotating ring 205 to rotate. The connecting block 302 is symmetrically fixedly connected to the left and right sides of the fixed ring 301, and an opening 303 is provided on one side of the connecting block 302. The positioning block 304 is slidably connected to the upper and lower sides of the connecting block 302, and the baffle 305 is fixedly connected to the top of the positioning block 304.

[0028] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the outer surface of the movable ring 204 is provided with a threaded block, and the movable ring 204 is threadedly connected to the upper cylinder 201 through the threaded block and the threaded groove 202.

[0029] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the limiting spring 306 is fixedly connected between the baffle 305 and the top surface of the connecting block 302, and the limiting spring 306 is sleeved on the outside of the positioning block 304. The positioning block 304 has an inclined surface on the open side near the opening 303.

[0030] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that one side of the mounting block 206 has an inclined surface that matches the angle of the inclined surface of the positioning block 304, and the interior of the mounting block 206 has a positioning hole 207 that matches the size of the positioning block 304.

[0031] When the mounting block 206 is inserted into the opening 303, the inclined surface of the mounting block 206 presses against the inclined surface of the positioning block 304, causing the positioning block 304 to retract above the connecting block 302 without affecting the continued installation of the mounting block 206, until the mounting block 206 is completely installed into the opening 303. At this time, under the elastic action of the limit spring 306, the baffle 305 is reset, thereby causing the positioning block 304 to extend into the positioning hole 207, thus fixing the installation of the mounting block 206.

[0032] As can be seen from the above working process, the length of the protective sleeve 2 can be adjusted by rotating the moving ring 204 in the threaded groove 202, so that the anti-slip sleeve 2 can be used for platinum resistance thermometer bodies 1 of different sizes, thereby improving the applicability and practicality of the product.

[0033] Further as Figure 1 , Figure 2 and Figure 4As shown, it is worth noting that the shock-absorbing mechanism 4 consists of a first fixed block 401, a rotating rod 402, a second fixed block 403, a clamping plate 404, a buffer spring 405, and a buffer layer 406. The first fixed block 401 is fixedly connected to the back of the upper cylinder 201. One end of the rotating rod 402 is rotatably connected to one side of the first fixed block 401. The second fixed block 403 is rotatably connected to the other end of the rotating rod 402. The clamping plate 404 is fixedly connected to the side of the second fixed block 403 near the thermal resistor.

[0034] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the buffer layer 406 is fixedly connected to one side of the clamping plate 404, and the material of the buffer layer 406 is set as a sponge layer.

[0035] The buffer layer 406 can be made of sponge or other highly elastic materials, which will absorb the impact energy after contact with it, thus playing a shock-absorbing role.

[0036] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the buffer spring 405 is fixedly connected between the clamping plate 404 and the upper cylinder 201, and a damper is provided inside the buffer spring 405.

[0037] The buffer spring 405 uses its elastic potential energy to absorb and dissipate impact energy. At the same time, the damper inside the buffer spring 405 slows down the spring's rebound speed to avoid secondary impact.

[0038] This solution has the following working process: When the platinum resistance thermometer body 1 is finished using and needs to be carried, firstly rotate the lower cylinder 203. By rotating the moving ring 204 in the threaded groove 202, the extension length of the moving ring 204 can be adjusted, thereby adjusting the length of the overall protective sleeve 2 to adapt to the length of the thermal resistor of different sizes of platinum resistance thermometer body 1, thus improving the applicability of the protective sleeve 2. Then, the protective sleeve 2 is put on the outside of the thermal resistor. Through the arc of the bottom surface of the thermal resistor, the clamps 404 on both sides can be pushed, which compresses the buffer spring 405, causing the rotating rod 402 to rotate, so that the thermal resistor can pass through the anti-vibration mechanism 4 on both sides until the rotating ring 205 is inserted. Inside the annular groove on the bottom surface of the fixing ring 301, rotate the protective sleeve 2 to pull the mounting block 206 into the opening 303. The inclined surface of the mounting block 206 presses against the inclined surface of the positioning block 304, causing the positioning block 304 to retract above the connecting block 302 without affecting the continued installation of the mounting block 206. Until the mounting block 206 is completely installed inside the opening 303, the baffle 305 is reset under the elastic action of the limit spring 306, thereby causing the positioning block 304 to extend into the positioning hole 207, fixing the installation of the mounting block 206, thus fixing the overall installation of the protective sleeve 2. At the same time, the internal shockproof mechanism 4 clamps and fixes the thermal resistor, improving the protective performance.

[0039] When the platinum resistance thermometer body 1 is subjected to an external impact, the upper cylinder 201 and lower cylinder 203 act as the first line of defense, directly receiving the impact. The rotating rod 402 disperses the impact force, causing the clamping plate 404 to move, which compresses the buffer spring 405. The buffer spring 405 uses its elastic potential energy to further absorb and dissipate the impact energy. At the same time, the damper inside the buffer spring 405 slows down the spring's rebound speed, preventing secondary impacts. Finally, the buffer layer 406 absorbs the impact energy, protecting the internal platinum resistance thermometer body 1.

[0040] In summary: the length of the protective sleeve 2 can be adjusted by rotating the movable ring 204 in the threaded groove 202, making the anti-slip sleeve 2 suitable for platinum resistance thermometer bodies 1 of different sizes, thus improving the applicability and practicality of the product; the connection mechanism 3 makes the installation and removal of the protective sleeve 2 simple and quick, improving the practicality and ease of use of the platinum resistance thermometer body 1, while ensuring the stability of the installation; the multi-layer buffer design of the shockproof mechanism 4 effectively reduces the damage to the platinum resistance thermometer body 1 from external impacts, improves the safety of the platinum resistance thermometer body 1 during carrying, and extends the service life of the thermometer.
