Description

Technical Field

[0001] This utility model belongs to the field of thermistor sensor technology, and in particular relates to a protective device for a high-precision thermistor sensor. Background Technology

[0002] The protective device for high-precision thermistor sensors is a structural component designed specifically to protect sensitive temperature sensing elements. It refers to the physical barrier system surrounding the thermistor to isolate external environmental interference, maintain measurement stability, and extend the sensor's lifespan.

[0003] Traditional high-precision thermistor sensors typically use protective housings to protect them from impacts and other damage. However, these housings are usually integrated and require screws for fixation. This makes it difficult to quickly open the housing when maintaining the high-precision thermistor sensor, and the frequent installation and removal of the screws can easily lead to stripping, affecting subsequent fixation. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for high-precision thermistor sensors. By setting a clamping mechanism, specifically, the cover plate is inserted into the front of the protective shell via a fixing base, allowing the clamping block to smoothly enter the interior of the protective shell. The clamping block, under the action of a spring, tightly adheres to the inner wall of the protective shell, thus fixing the cover plate in place through clamping. This allows for quick installation of the cover plate, protecting the thermistor sensor body. The cover plate can be removed by pulling it forcefully. This method is more convenient and efficient for subsequent maintenance of the thermistor sensor body, solving the problem of traditional protective devices that are difficult to open quickly when maintaining high-precision thermistor sensors, and the frequent installation and removal of screws that easily lead to stripped threads.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a protective device for a high-precision thermistor sensor, comprising a mounting plate, a protective shell positioned on the front of the mounting plate, a cover plate positioned on the front of the protective shell, and a thermistor sensor body mounted on the front of the mounting plate by screws. It also includes:

[0007] A clamping mechanism includes a fixed base fixedly connected to the back of a cover plate. The fixed base has a hollow interior. Clamping blocks are slidably connected to the left and right sides of the fixed base. A partition is fixedly connected to the inner wall of the fixed base. A telescopic rod is fixedly connected between the partition and the clamping blocks. A spring is sleeved on the outer side of the telescopic rod. Several protruding teeth are provided on the outer side of the clamping blocks.

[0008] A sealing mechanism is provided at the top and bottom of the protective housing, and the sealing mechanism is used to seal the connected wires;

[0009] The outer back of the clamping block is sloped, and the outer side of the clamping block contacts the inner wall of the protective shell through protruding teeth.

[0010] Furthermore, protruding plates are fixedly connected to the left and right sides of the protective shell, and the protruding plates are fixedly connected to the mounting plate by screws. The top and bottom of the mounting plate are fixedly connected to the wiring tubes. After the thermistor sensor body is installed, the wires are passed through the wiring tubes and connected to the thermistor sensor body.

[0011] The conduit is used to insert a wire and connect the wire to the thermistor sensor body.

[0012] Furthermore, the sealing mechanism includes a rubber sleeve fixedly connected to the end of the connector tube, and a strap is fixedly connected to the outside of the rubber sleeve. The surface of the strap is provided with a snap fastener. After the strap tightens the rubber sleeve, it is fixed by the snap fastener.

[0013] The rubber sleeve is used to contact the surface of the wire, and the strap is used to tighten and fix the rubber sleeve.

[0014] Furthermore, the inner side of the clamping block is U-shaped, the surface of the clamping block contacts the inner wall of the fixing seat, one end of the spring is fixedly connected to the surface of the partition plate, and the other end of the spring is fixedly connected to the inner wall of the clamping block; since the outer back of the clamping block is inclined, the protective shell will push the clamping block when the cover plate is installed, so that the clamping block can smoothly enter the interior of the protective shell;

[0015] The spring uses its elastic force to push the clamping block, and the telescopic rod is used to limit the movement distance of the clamping block.

[0016] Furthermore, a positioning frame is fixedly connected to the front of the mounting plate, and the outer side of the positioning frame is inserted into the inner side of the protective shell. The positioning frame is used to position the protective shell; the back of the protective shell is inserted into the positioning frame to position and install the protective shell on the mounting plate.

[0017] Furthermore, the protective shell has a raised front end with several positioning grooves, and several positioning blocks are fixedly connected to the back of the cover plate. The positioning blocks correspond to the positioning grooves and are inserted into the protective shell through the positioning grooves. After the cover plate is installed on the protective shell, the back of the cover plate contacts the front of the protective shell. The protective shell and the cover plate are used to protect the main body of the thermistor sensor. After the cover plate is installed, the positioning blocks will be inserted into the positioning grooves to position the cover plate and improve the stability of the cover plate after installation.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model features a clamping mechanism. Specifically, the cover plate is inserted into the front of the protective shell via a fixing base, allowing the clamping block to smoothly enter the interior of the protective shell. The clamping block, under the action of spring force, adheres tightly to the inner wall of the protective shell, thereby fixing the cover plate through clamping. This allows for quick installation of the cover plate and protection of the thermistor sensor body. The cover plate can be removed by pulling it forcefully. This method is more convenient for subsequent maintenance of the thermistor sensor body and is more efficient.

[0020] 2. This utility model sets up a sealing mechanism, specifically by connecting the wire to the main body of the thermistor sensor. After the wire is installed, the strap is pulled to tighten the rubber sleeve and wrap the strap around it. Then, it is fixed by attaching the adhesive tape, so that the rubber sleeve and the wire are tightly attached to each other, achieving a sealing effect and greatly reducing the amount of dust entering the protective shell.

[0021] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0030] 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 scope of protection of the present utility model.

[0031] Please see Figures 1-5 As shown, this utility model is a protective device for a high-precision thermistor sensor, including a mounting plate 1, a protective shell 11 positioned on the front of the mounting plate 1, a cover plate 12 positioned on the front of the protective shell 11, and a thermistor sensor body 13 mounted on the front of the mounting plate 1 by screws. It also includes:

[0032] The clamping mechanism 2 includes a fixed base 21 fixedly connected to the back of the cover plate 12. The fixed base 21 has a hollow interior. Clamping blocks 22 are slidably connected to the left and right sides of the fixed base 21. A partition 23 is fixedly connected to the inner wall of the fixed base 21. A telescopic rod 24 is fixedly connected between the partition 23 and the clamping blocks 22. A spring 241 is sleeved on the outer side of the telescopic rod 24. Several protruding teeth are provided on the outer side of the clamping blocks 22. The cover plate 12 is inserted into the front of the protective shell 11 through the fixed base 21, allowing the clamping blocks 22 to smoothly enter the protective shell 11. The clamping blocks 22 will be tightly pressed against the inner wall of the protective shell 11 by the elastic force of the spring 241, thereby fixing the cover plate 12 through the clamping effect. This quickly completes the installation of the cover plate 12 and protects the thermistor sensor body 13. The cover plate 12 can be removed by pulling it forcefully. This method is more convenient for subsequent maintenance of the thermistor sensor body 13 and is more efficient.

[0033] The sealing mechanism 3 is provided at the top and bottom of the protective shell 11 and is used to seal the connected wires. The outer back of the clamping block 22 is set with a slope, and the outer side of the clamping block 22 contacts the inner wall of the protective shell 11 through the protruding teeth.

[0034] The protective shell 11 has protruding plates 111 fixedly connected to the left and right sides. The protruding plates 111 are fixedly connected to the mounting plate 1 by screws. The mounting plate 1 has a wire insertion tube 14 fixedly connected to the top and bottom. The wire insertion tube 14 is used to insert wires and connect the wires to the thermistor sensor body 13.

[0035] The sealing mechanism 3 includes a rubber sleeve 31 fixedly connected to the end of the connector 14. A strap 32 is fixedly connected to the outside of the rubber sleeve 31, and a tab 33 is provided on the surface of the strap 32. When the wire is connected to the thermistor sensor body 13, the strap 32 is pulled after the wire is installed, thereby tightening the rubber sleeve 31 and wrapping the strap 32. Then, the tab 33 is used to stick and fix it, so that the rubber sleeve 31 is tightly attached to the wire, achieving a sealing effect and greatly reducing the entry of dust into the protective shell 11. The rubber sleeve 31 is used to contact the surface of the wire, and the strap 32 is used to tighten and fix the rubber sleeve 31.

[0036] The inner side of the clamping block 22 is U-shaped, and the surface of the clamping block 22 contacts the inner wall of the fixed base 21. One end of the spring 241 is fixedly connected to the surface of the partition 23, and the other end of the spring 241 is fixedly connected to the inner wall of the clamping block 22. The spring 241 uses its elastic force to push the clamping block 22, and the telescopic rod 24 is used to limit the movement distance of the clamping block 22.

[0037] The mounting plate 1 has a positioning frame 15 fixedly connected to the front. The outer side of the positioning frame 15 is inserted into the inner side of the protective shell 11. The positioning frame 15 is used to position the protective shell 11.

[0038] The protective shell 11 has a raised front end and several positioning grooves 112. Several positioning blocks 121 are fixedly connected to the back of the cover plate 12. The positioning blocks 121 correspond to the positioning grooves 112 and are inserted into the protective shell 11 through the positioning grooves 112. After the cover plate 12 is installed on the protective shell 11, the back of the cover plate 12 contacts the front of the protective shell 11. The protective shell 11 and the cover plate 12 are used to protect the thermistor sensor body 13.

[0039] One specific application of this embodiment is:

[0040] Mounting plate 1 is installed on the equipment that needs to detect temperature using screws. Then, the back of the protective shell 11 is inserted into the positioning frame 15 and positioned on the mounting plate 1. Screws are then installed on the protruding plate 111 to lock and fix the protective shell 11. The thermistor sensor body 13 is then installed on the mounting plate 1 using screws. Since the front of the protective shell 11 is open, it is convenient for the operator to operate. The wire is then passed through the insertion tube 14 and the rubber sleeve 31 and connected to the thermistor sensor body 13. After the wire is installed, the strap 32 is pulled to tighten the rubber sleeve 31 and wrap the strap 32, so that the rubber sleeve 31 is in close contact with the wire, achieving a sealing effect and greatly reducing dust from entering the protective shell 11. After it is wrapped tightly, the strap 32 is fixed by attaching the adhesive tape 33.

[0041] Finally, the cover plate 12 is inserted into the front of the protective shell 11 via the fixing base 21. Since the back of the clamping block 22 is set at an angle, the clamping block 22 will be pushed during installation, causing the telescopic rod 24 to retract and the spring 241 to be squeezed, thus allowing the clamping block 22 to smoothly enter the interior of the protective shell 11. Subsequently, the clamping block 22 will be pressed tightly against the inner wall of the protective shell 11 under the action of the spring force of the spring 241, thereby fixing the cover plate 12 through the clamping effect. The clamping block 22 is provided with multiple protruding teeth, which can increase the friction and improve the fixing effect. Finally, the positioning block 121 on the cover plate 12 is inserted into the positioning groove 112 on the protective shell 11, thus completing the installation of the cover plate 12 and protecting the thermistor sensor body 13. When the thermistor sensor body 13 needs to be repaired, the cover plate 12 is pulled forcefully to make the clamping block 22 detach from the protective shell 11, thus quickly completing the disassembly. This method of installing and removing the cover plate 12 by pressing and pulling makes subsequent maintenance work more convenient and efficient.
