[0002] A temperature sensor is a device used to measure temperature. It senses temperature changes and converts them into electrical signals (such as voltage, current, or digital signals) for display, recording, or control. Temperature sensors are widely used in various fields, including industry, healthcare, environmental monitoring, and home automation.

[0003] In actual use, the existing temperature sensors and the sensor probes matched with them are mostly assembled by a tight fitting method. This assembly method has a stable connection and is not easy to loosen. However, during use, when the sensor probe is hit or otherwise physically damaged and needs to be replaced, considering the connection stability of the sensor probe, the tight fitting probe and the sensor are cumbersome and inconvenient to disassemble and assemble, and tools are required for disassembly and installation, which increases the maintenance time and labor cost. At the same time, there are also sensor probes with threaded connections, but this type of probe and sensor adopts an adapter assembly. The same model temperature sensor cannot be replaced with probes of different sizes, resulting in high replacement costs. Therefore, a temperature sensor that is easy to replace the probe is proposed to solve the above problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example

[0023] Depend on Figure 1-4 Provided is a temperature sensor for facilitating probe replacement, comprising a temperature sensor body 1;

[0024] The temperature sensor body 1 is surrounded by a plurality of connecting shafts 11, the ends of which are commonly connected to a limit ring 12, on which a probe quick-release assembly 2 is assembled, and the temperature sensor probe body 3 is detachably assembled in the probe quick-release assembly 2;

[0025] The probe quick-release assembly 2 includes a positioning seat 21 mounted on the limiting ring 12. An intermediate shaft tube 22 is integrally provided in the positioning seat 21. An adjustment shaft 23 is rotatably provided at one end of the intermediate shaft tube 22, and a positioning disk 24 is embedded at the other end thereof. Four clamping cones 242 are provided on one side of the positioning disk 24.

[0026] The intermediate shaft tube 22, the adjusting shaft 23 and the positioning plate 24 are all provided with holes and slots, and they are in continuous communication;

[0027] The temperature sensor probe body 3 is passed through one end of the positioning disk 24 , and an end of the temperature sensor probe body 3 passes through the positioning disk 24 and extends through the adjustment shaft 23 .

[0028] In this embodiment, in actual use, the temperature sensor probe body 3 can be quickly clamped or released in the probe quick-release assembly 2 through the mutual movement and coordination of multiple structures in the probe quick-release assembly 2, thereby realizing quick disassembly and assembly on the temperature sensor body 1. Compared with the traditional fastening-type interlocking installation, the probe quick-release assembly 2 of the present application can quickly disassemble and assemble the temperature sensor probe body 3 without using additional tools. At the same time, compared with threaded assembly, the probe quick-release assembly 2 of the present application can provide a more uniform clamping force through its annular clamping design, and can make the temperature sensor body 1 adapt to temperature sensor probe bodies 3 of different diameters and lengths, thereby enhancing the detection flexibility of the temperature sensor body 1, so that it can meet various application requirements.

[0029] It should be noted that the temperature sensor probe body 3 and the temperature sensor body 1 are electrically connected through a wire, the power supply connection method is the existing technology, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0030] Specifically, refer to Figure 3-4 The four clamping cone pieces 242 are integrally arranged on the side of the positioning plate 24 and are in the form of separated sheet cones. The four clamping cone pieces 242 are formed by cutting a complete cone into equal parts.

[0031] In this embodiment, in actual use, the clamping cone 242 is in the form of a sheet cone, so that it can clamp the outer wall of the temperature sensor probe body 3 in a ring-shaped clamping manner during use, thereby achieving the fastening and limiting of the temperature sensor probe body 3. At the same time, in a more preferred embodiment, a rubber pad is adhered to the end wall of each clamping cone 242, and the rubber pad can further increase the clamping and limiting of the temperature sensor probe body 3.

[0032] Specifically, refer to Figure 3-4 The inner circumferential surface of the adjusting shaft 23 is provided with an inner conical surface 232 , the inner wall surface of the inner conical surface 232 abuts against the conical surfaces of the clamping cone pieces 242 and surrounds the conical surfaces of the clamping cone pieces 242 .

[0033] In this embodiment, the conical surface of the inner conical surface 232 is formed at the same angle as the conical surfaces of the plurality of clamping cone pieces 242. In actual use, when the user rotates the adjustment shaft 23 in the forward direction, the adjustment shaft 23 will gradually separate from the intermediate shaft tube 22, thereby causing the inner conical surface 232 inside the intermediate shaft tube 22 to gradually separate from the conical surface restriction of the clamping cone pieces 242, allowing the four clamping cone pieces 242 to expand outward along the center of the positioning plate 24. At this time, the four clamping cone pieces 242 are in a relaxed state.

[0034] Furthermore, in the same manner as in the above embodiment, when the user rotates the adjustment shaft 23 in the opposite direction, the inner conical surface 232 will gradually clamp the clamping cone pieces 242, so that the clamping cone pieces 242 will gradually be in a clamping state, thereby achieving the clamping limit of the temperature sensor probe body 3.

[0035] Specifically, refer to Figure 3-4 The inner circumference of the intermediate shaft tube 22 is provided with four inserting plates 222 protruding along its center; the outer circumference of the positioning plate 24 is provided with four positioning notches 241 along its center, and the four positioning notches 241 are adapted to the inserting plates 222 .

[0036] In this embodiment, during use, the provided insert plate 222 can be used to cooperate with the positioning notch 241 to achieve the embedded installation of the positioning disk 24 in the intermediate shaft tube 22. The user can simply align the positioning notch 241 with the insert plate 222 and insert the positioning disk 24 as a whole into the intermediate shaft tube 22.

[0037] Specifically, refer to Figure 2-4 The inner circumference of the intermediate shaft tube 22 is provided with an internal thread line 221 , and the outer circumference of the adjusting shaft 23 is provided with an external thread line 231 ; the internal thread line 221 is adapted to the external thread line 231 .

[0038] In this embodiment, during use, the provided internal thread line 221 can be used to cooperate with the external thread line 231 to achieve a threaded connection between the intermediate shaft tube 22 and the adjusting shaft 23 .

[0039] The temperature sensor of the utility model is easy to replace the probe:

[0040] Step 1: In actual use, when the user adjusts the probe quick-release assembly 2 to achieve the disassembly and assembly of the temperature sensor probe body 3, the user first rotates the end of the adjusting shaft 23. At this time, due to the threaded connection between the adjusting shaft 23 and the intermediate shaft tube 22, when the user rotates the adjusting shaft 23 in the forward direction, the set adjusting shaft 23 will gradually disengage from the intermediate shaft tube 22, thereby causing the inner conical surface 232 inside the intermediate shaft tube 22 to gradually disengage from the conical surface restriction of the clamping cone 242, allowing the four clamping cones 242 to expand outward along the center of the positioning plate 24. At this time, the four clamping cones 242 are in a relaxed state;

[0041] Step 2: When the clamping cone 242 is in a relaxed state, the user then passes the temperature sensor probe body 3 to be fixed along the bottom of the positioning plate 24 through the intermediate shaft tube 22 and the adjustment shaft 23 until the connection end of the temperature sensor probe body 3 is connected to the signal end in the temperature sensor body 1. The user can then use a wire to electrically connect the temperature sensor body 1 and the temperature sensor probe body 3.

[0042] Step 3: After the temperature sensor probe body 3 is electrically connected to the temperature sensor body 1, the user can reversely rotate the adjustment shaft 23 again, so that the adjustment shaft 23 gradually moves into the intermediate shaft tube 22. At this time, the inner conical surface 232 can gradually surround and restrict the conical surface of the clamping cone piece 242 until the inner walls of several clamping cone pieces 242 clamp the outer wall of the temperature sensor probe body 3. At this time, the clamping of the temperature sensor probe body 3 can be completed by restricting the clamping cone piece 242 on the temperature sensor probe body 3. Similarly, when the user needs to disassemble and replace the temperature sensor probe body 3 again, the user can rotate the adjustment shaft 23 again to disengage it from the intermediate shaft tube 22.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
