[0024] Please refer to the following: Figures 1 to 6The adjustable wireless temperature measuring device provided by this utility model will now be described. The adjustable wireless temperature measuring device includes a main body 10, at least one adjusting sleeve 20, a temperature measuring probe 30, and an adjusting component 40. The main body 10 has a ring structure, and a first sliding groove 11 extending radially within the main body 10 is provided. The first sliding groove 11 opens towards the inner circumferential surface of the main body 10. The adjusting sleeve 20 is detachably connected to the inner ring of the main body 10. The adjusting sleeve 20 is provided with a through hole corresponding to the opening of the first sliding groove 11. When multiple adjusting sleeves 20 are provided, the multiple adjusting sleeves 20 are sequentially fitted from the inside to the outside, and adjacent two adjusting sleeves 20 are detachably connected. The temperature measuring probe 30 is slidably fitted in the first sliding groove 11 and is used to extend out of the inner circumferential surface of the innermost adjusting sleeve 20. The adjusting component 40 is provided inside the main body 10 and is used to drive the temperature measuring probe 30 to adjust radially along the main body 10.

[0025] It should be noted that the temperature probe 30 uses a high-precision thermistor as its core sensing element. It needs to be powered on when it is working. The heat generated when the switch contacts are working is transferred to the thermistor. The resistance value of the thermistor changes regularly with the temperature. The temperature probe 30 also integrates a simple signal processing circuit. The circuit provides a stable reference current or voltage to the thermistor. By detecting the change in voltage or current, the resistance value is converted into a corresponding analog electrical signal. The electrical signal is then digitally processed to convert it into a temperature value, which can be transmitted to the receiving terminal via a wireless module (such as Bluetooth).

[0026] In this embodiment of the adjustable temperature measuring device, when in use, a corresponding number of adjusting sleeves 20 are selected according to the size of the switch contact, so that the innermost adjusting sleeve 20 is just fitted onto the switch contact. After the adjusting sleeve 20 is fixed, the temperature measuring probe 30 is driven to extend through the adjusting component 40, so that the temperature measuring probe 30 protrudes from the inner circumferential surface of the innermost adjusting sleeve 20, thereby abutting against the outer circumferential surface of the switch contact for temperature measurement.

[0027] Compared with the prior art, the adjustable wireless temperature measuring device provided in this embodiment can be used in combination with detachable adjustment sleeves 20. Different numbers of adjustment sleeves 20 can be installed according to the actual diameter of the switch contact, thereby changing the overall inner diameter of the inner ring of the device and improving the versatility of the temperature measuring device. The first slide groove 11 provides a stable radial movement path for the temperature measuring probe 30. The adjustment component 40 can drive the probe to accurately adjust the extension length, ensuring that the probe can fully and stably contact the contact surface in different contact size adaptation scenarios, avoiding temperature measurement errors caused by poor contact.

[0028] In some embodiments, a specific installation method for the aforementioned adjusting sleeve 20 can be as follows: Figures 1 to 2 The structure shown. See also Figures 1 to 2The outer ring of the adjusting sleeve 20 is provided with a protrusion 21, and both the inner ring of the main body 10 and the inner ring of the adjusting sleeve 20 are provided with grooves 22. The protrusion 21 on the adjusting sleeve 20 cooperates with the groove 22 of the adjacent outer ring. The protrusion 21 penetrates the adjusting sleeve 20 along the axial direction, and similarly, the groove 22 also penetrates the adjusting sleeve 20 along the axial direction. Correspondingly, the groove 22 on the main body 10 also penetrates the main body 10 along the axial direction, and the axial direction of the main body 10 coincides with the axial direction of the adjusting sleeve 20.

[0029] When installing the adjusting sleeve 20, adjust the protrusions 21 and grooves 22 on two adjacent adjusting sleeves 20 to correspond, or adjust the protrusions 21 on the adjusting sleeve 20 to correspond with the grooves 22 on the main body 10, and slide the adjusting sleeve 20 into the inner ring of the main body 10 along the axial direction of the main body 10. Then, install each adjusting sleeve 20 sequentially through the same process, adjusting the end face of the adjusting sleeve 20 to be flush with the end face of the main body 10, and it is ready for use. In this embodiment, protrusions 21 are provided on the outer ring of the adjusting sleeve 20 to ensure that the adjusting sleeve 20 located in the innermost ring is fitted onto the switch contact. When the head is on the outer periphery, there will be no protruding structure colliding with the switch contact, extending the service life of the switch contact; the mating structure of the protrusion 21 and the groove 22 can provide precise positioning for the installation of the adjusting sleeve 20, and the installer can achieve accurate installation without repeatedly adjusting the position of the adjusting sleeve 20, which greatly shortens the installation time and improves the installation efficiency; the tight fit between the protrusion 21 and the groove 22 can effectively limit the circumferential rotation of the adjusting sleeve 20 during operation, avoid the adjusting sleeve 20 from loosening due to the vibration of the switch contact or the weight of the device itself, and ensure assembly stability.

[0030] As a variation, the protrusion 21 and groove 22 may be omitted, and installation can be achieved by adjusting the outer ring of the sleeve 20 and the inner ring of the main body 10 through an interference fit.

[0031] In some embodiments, a modified installation method of the adjusting sleeve 20 can be as follows: Figures 4 to 6 The structure shown. See also Figures 4 to 6 The main body 10 has a sliding rod 12 at its end, which slides radially against the main body 10. Multiple slots 13 are provided on the side of the sliding rod 12 facing the main body 10, spaced radially apart, and used to engage with adjusting sleeves 20. The length of the sliding rod 12 extending beyond the inner circumference of the main body 10 is adjusted by the number of adjusting sleeves 20 required. For example, if three sliding sleeves are required, three slots 13 are needed within the length of the sliding rod 12 extending beyond the inner circumference of the main body 10. Each slot 13 engages with one adjusting sleeve 20, thus fixing both the adjusting sleeve 20 and the sliding rod 12.

[0032] In this embodiment, multiple slots 13 are radially spaced along the main body 10. Each slot 13 corresponds to a fixed position of an adjustment sleeve 20, and thus corresponds to an inner ring size of a temperature measuring device. The sliding rod 12 selects different numbers of slots 13 to extend out of the inner ring of the main body 10 and cooperates with the corresponding number of adjustment sleeves 20. This enables a step-by-step precise adjustment of the inner ring size of the device, meeting the adaptation requirements of different sized switch contacts. The axial fixation of the adjustment sleeve 20 by the slots 13 prevents the adjustment sleeve 20 from falling off due to axial displacement, ensuring a reliable connection.

[0033] In some embodiments, a specific cooperation method between the slide bar 12 and the main body 10 can be as follows: Figures 5 to 6 The structure shown. See also Figures 5 to 6 The main body 10 has a recessed end face forming a second groove 14. The slide rod 12 is located inside the second groove 14 and slides in cooperation with it. An insert rod 15 is provided on an inner wall of the second groove 14 away from the axial direction of the main body 10. The end of the slide rod 12 is provided with an insertion hole 122 that cooperates with the insert rod 15. When the slide rod 12 is not in use, it can slide into the interior of the second groove 14 and be fixed in place by cooperating with the insert rod 15 on the second groove 14, preventing the slide rod 12 from sliding out of the inner circumference of the main body 10 during transportation and causing it to break. The slide rod 12 is located inside the second groove 14, which can prevent it from protruding from the end face of the main body 10, making it convenient for stacking the main bodies 10 and making reasonable use of space. The second groove 14 provides guidance for the sliding process of the slide rod 12, making the sliding of the slide rod 12 smoother and easier to operate.

[0034] In some embodiments, an improved fit between the second groove 14 and the slide rod 12 can be as follows: Figure 6 The structure shown. See also Figure 6 The second slide groove 14 has a first limiting step 141 at one end near the axial direction of the main body 10, and the slide rod 12 has a second limiting step 121 at the end away from the axial direction of the main body 10. When the slide rod 12 moves to its limit position, the second limiting step 121 abuts against the first limiting step 141. The opening on the first limiting step 141 allows the slide rod 12 to extend out. The diameter of the second limiting step 121 is larger than the opening of the first limiting step 141. Therefore, when the second limiting step 121 abuts against the first limiting step 141, the slide rod 12 is prevented from extending further, thus preventing the slide rod 12 from falling out of the second slide groove 14 and effectively limiting the travel of the slide rod 12.

[0035] In some embodiments, a specific implementation of the adjustment member 40 may employ, as follows: Figure 1 and Figure 4 The structure shown. See also Figure 1 and Figure 4The first slide groove 11 has an internal threaded hole on one side wall away from the axis of the main body 10. The adjusting member 40 is threadedly connected to the internal threaded hole, and one end extends out of the first slide groove 11.

[0036] The adjusting component 40 is a threaded rod structure with an external thread on its surface that matches the internal threaded hole. The length of the threaded rod is designed such that one end connects to the temperature probe 30, and the other end extends out of the first sliding groove 11. The length of the extended part facilitates the operation of the adjusting component 40. By rotating the adjusting component 40, the temperature probe 30 can be moved slightly and precisely along the radial direction of the main body 10 using the helical transmission of the thread, achieving high adjustment accuracy. The threaded connection has a self-locking characteristic; once the adjusting component 40 is adjusted to the correct position, it can maintain its current position under the action of its own thread friction without the need for an additional locking structure, thus ensuring that the temperature probe 30 remains in the current position.

[0037] Specifically, one end of the adjusting member 40 extending into the first sliding groove 11 can directly abut against the temperature probe 30. When the adjusting member 40 moves axially closer to the main body 10, it can abut against the temperature probe 30 as it extends axially closer to the main body 10. To return to its original position, the adjusting member 40 needs to be rotated in the opposite direction, and then the temperature probe 30 is pushed into the first sliding groove 11 by external force. Alternatively, the adjusting member 40 can cooperate with the temperature probe 30 through a bearing, so that when the adjusting member 40 rotates forward and backward, it can drive the temperature probe 30 to move radially back and forth along the main body 10, making it more convenient to use.

[0038] In some embodiments, an improved implementation of the adjustment member 40 may employ, as follows: Figure 1 and Figure 4 The structure shown. See also Figure 1 and Figure 4 The adjusting component 40 has a drive wheel 41 at one end outside the first slide groove 11. The drive wheel 41 can be welded or keyed to the end of the adjusting component 40. Manually turning the drive wheel 41 can drive the adjusting component 40 to rotate. The toothed structure on the outer circumference of the drive wheel 41 can increase friction and facilitate the turning operation.

[0039] Specifically, the outer surface of the temperature probe 30 is provided with scale lines 32. When adjusting the position of the temperature probe 30, the length of the innermost adjusting sleeve 20 protruding from the temperature probe 30 can be directly determined by observing the scale lines 32, so as to correspond to the size of the switch contact, ensuring that the temperature probe 30 can abut against the outer surface of the switch contact after installation, thus ensuring the accuracy of temperature measurement.

[0040] In some embodiments, an improved implementation of the adjusting sleeve 20 may employ, as follows: Figures 4 to 5 The structure shown. See also Figures 4 to 5Both the main body 10 and the adjusting sleeve 20 have rubber pads 23 on their inner circumferential surfaces. The elasticity of the rubber pads 23 can eliminate the mating noise between the adjusting sleeve 20 and the main body 10 or adjacent adjusting sleeves 20, while increasing the friction between the adjusting sleeve 20 and the main body 10 or adjacent adjusting sleeves 20, thus improving the connection stability. When the adjusting sleeve 20 is fitted on the outer circumference of the switch contact, the rubber pads 23 can also prevent hard collisions between the adjusting sleeve 20 and the switch contact, playing a buffering role and protecting the surface of the switch contact from being scratched.

[0041] In some embodiments, an improved cooperation method between the temperature probe 30 and the first slide groove 11 can be adopted as follows: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The first slide groove 11 has a guide groove 111 on its side wall, which extends radially along the main body 10. The outer side of the temperature probe 30 has a slider 31 that slides in cooperation with the guide groove 111. The two opposite side walls of the first slide groove 11 each have a guide groove 111. The guide groove 111 has a rectangular groove 22 structure and extends radially along the main body 10. The length of the guide groove 111 is the same as the length of the first slide groove 11. When the temperature probe 30 slides along the first slide groove 11, the slider 31 will slide synchronously in the guide groove 111, providing precise guidance for the movement of the temperature probe 30.

[0042] In this embodiment, the cooperation between the guide groove 111 and the slider 31 provides a precise guide trajectory for the radial movement of the temperature probe 30, ensuring that the probe always moves radially along the body 10.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
