Description
Technical Field
[0001] This utility model relates to the field of temperature measuring equipment technology, specifically a temperature measuring device for power fittings. Background Technology
[0002] Power fittings are metal accessories that connect and combine various devices in a power system. They are mainly used to transmit mechanical loads, electrical loads, and provide protection. Since heat is generated when current passes through power fittings, some fittings may be damaged due to overheating, which will affect the operating efficiency of the power system. Therefore, temperature measuring equipment is required for temperature detection.
[0003] Existing patent CN222866077U discloses a temperature measuring device for power fittings, relating to the field of temperature measuring devices. It includes a fixed mounting base and a fixed housing. A fixed shell is fixedly mounted on one side of the fixed housing, and a movable plate is slidably mounted on the inner wall of the fixed shell. A rotating column is mounted on one side of the movable plate, and a clamping plate is fixedly connected to the outer wall of the rotating column. This invention removes the movable plate from the fixed shell, and the clamping plate, under the action of a torsion spring shaft, comes into contact with the power fitting. The temperature measuring mechanism on the clamping plate measures the temperature of the power fitting. When the clamping plate comes into contact with the power fitting, a protrusion releases the pressure on the blocking mechanism, allowing it to extend out of the movable plate. This prevents the movable plate from sliding left and right during operation, which could cause the clamping plate to detach from the power fitting. The entire device is directly installed on the cable, and the clamping plate is controlled by the elasticity of the torsion spring shaft. This allows it to adapt to different models of power fittings, effectively reducing installation costs.
[0004] Based on the search of the aforementioned patents and in conjunction with existing temperature measuring devices, it was found that although the aforementioned temperature measuring devices can detect the temperature of electrical fittings, their application range is narrowed and their practicality is reduced because they are connected and fixed to the wires via a fixed bracket. However, the fixed bracket is of a fixed size and can only fix wires of a single size. Utility Model Content

The first connecting seat 1 and the second connecting seat 11 can be placed outside the cable, and the plug plate 28 can be inserted into the socket 22. The second arc-shaped blocks 29 can squeeze the first arc-shaped block 26 to move it. The movement of the first arc-shaped block 26 can drive the slider 24 to squeeze the first spring 25 to deform it. The return of the first spring 25 can drive the first arc-shaped block 26 to return to its original position. The second arc-shaped block 29 is locked in place, allowing the first connecting seat 1 and the second connecting seat 11 to be connected and fixed. Multiple second arc-shaped blocks 29 and clamping grooves 30 can be used to fix cables of different thicknesses. Guide grooves 71 are respectively provided on both sides of the slide groove 23. Guide blocks 72 are fixedly connected to both sides of the slider 24, and the guide blocks 72 are slidably connected to the guide grooves 71.

The temperature sensor body 42 and the alarm body 37 are electrically connected to the controller body 31 through wires. The rotation of the screw 34 can drive the drive plate 35. The moving plate 35 and the movable plate 36 move, which in turn drives the connecting plate 41 and the temperature sensor body 42 to move vertically, so that the temperature sensor body 42 comes into contact with the power fittings. The second spring 40 deforms accordingly, which can buffer the pressure and protect the temperature sensor body 42. The temperature sensor body 42 can detect the temperature, and the alarm body 37 can sound an alarm. A rotation-prevention groove 51 is provided on one side of the fixed frame 33.

The second arc-shaped block 29 can contact the first arc-shaped block 26 and press the first arc-shaped block 26 to move it. The movement of the first arc-shaped block 26 can drive the slider 24 to move, which in turn can compress the first spring 25 to deform it. The return of the first spring 25 can drive the first arc-shaped block 26 to return to its original position, thus locking the second arc-shaped block 29. Since there are multiple second arc-shaped blocks 29, they can be adapted to cables of different thicknesses, thereby quickly connecting and fixing the first connecting seat 1 and the second connecting seat 11 to the cable. After fixing, rotating the handle 62 can drive the rotating... The rotating plate 61 and screw 34 rotate, which drives the drive plate 35 to move. The drive plate 35 moves the moving plate 36, which in turn moves the connecting plate 41. This causes the temperature sensor body 42 to move, making it contact the power fitting. The second spring 40 deforms accordingly, protecting the temperature sensor body 42. The temperature sensor body 42 can detect the temperature of the power fitting. The controller body 31 can transmit a signal to the alarm body 37. When the temperature is too high, the alarm body 37 is activated, alerting the staff to the location to be inspected. This is the entire working process of the device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.
