Description

Technical Field

[0001] The present invention belongs to the technical field of temperature clamps, and in particular relates to a temperature clamp that can be rotated to switch between high and low temperature modes. Background Art

[0002] Temperature detectors (most commonly, temperature clamps) are frequently used in HVAC technology. These clamps are attached to the pipes to measure temperature. They are typically divided into high-temperature clamps for measuring dew point and low-temperature clamps for measuring bubble point. The clamps transmit the measured dew point or bubble point temperature to a digital display. Maintenance personnel compare the dew point and bubble point temperatures recorded by the clamps with the retrieved temperatures to identify any faults in the air conditioning system.

[0003] Currently, most high and low temperature detectors on the market are separate, requiring users to purchase both a high-temperature detector and a low-temperature detector (each paired with a digital display that identifies high and low temperatures, with high corresponding to dew point and low corresponding to bubble point). This is expensive and inconvenient to carry around.

[0004] Therefore, it is necessary to implement high and low temperature detection and temperature type switching functions on the same temperature clamp. Although dials and buttons can be used to implement temperature type switching (i.e., switching between dew point and bubble point temperatures sent to the digital display), they are all located on one half of the clamp, which is not aesthetically pleasing, and the operating components are small and difficult to operate. Summary of the Invention

[0005] In view of the shortcomings of the existing high and low temperature mode switching structure of the universal temperature clamp for heating, the present invention provides a temperature clamp that can be rotated to switch the high and low temperature modes. The high temperature detection signal or the low temperature detection signal is switched by the rotating structure of the knob. Compared with the methods of dialing knobs, pressing buttons, etc., the operation of the knob is easier.

[0006] To achieve the above object, the present invention adopts the following technical solution: a temperature clamp for rotating and switching high and low temperature modes, the temperature clamp for rotating and switching high and low temperature modes comprises:

[0007] The temperature clamp body includes a pin shaft, two half clamps rotating relative to the pin shaft, a temperature sensor and a transmission module provided on the half clamps, the two half clamps including a first half clamp and a second half clamp, and the temperature sensor and the transmission module are connected;

[0008] The rotary switching mechanism includes a magnetic sensing element fixed to the first half of the clamp, a knob rotating relative to the pin, and a magnetic element linked to the knob. The magnetic sensing element is connected to the transmission module, and the knob is exposed on the two half clamps.

[0009] The magnetic element rotates with the rotation and switches between a low-temperature position and a high-temperature position, and the magnetic induction element senses different magnetic induction intensities in the low-temperature position and the high-temperature position, thereby sending different signals to the transmission module.

[0010] The temperature clamp for switching high and low temperature modes by rotation of the application has a rotation switching mechanism, which comprises a magnetic induction element and a magnetic element. The magnetic element rotates with the rotation and switches between a low-temperature position and a high-temperature position. The magnetic induction element senses different magnetic induction intensities in the low-temperature position and the high-temperature position, thereby sending different signals to the transmission module. When the magnetic element is in different positions, the magnetic induction element can generate two different signals to distinguish high and low temperatures. For example, when the magnetic element is in the low-temperature position, the magnetic induction element sends a low-temperature signal, indicating that the detected temperature is low (such as the bubble point temperature). When the magnetic element is in the high-temperature position, the magnetic induction element sends a high-temperature signal, indicating that the detected temperature is high (such as the dew point temperature). The rotation of the knob realizes the switching of high and low temperature signals. The knob is located at the axial end of the pin shaft, and the size of the knob can be larger, which is convenient to operate and more beautiful. The rotation structure of the knob is simpler than that of the existing technology, and there is no need to additionally set a separate shaft. The components are installed on the first half clamp or the second half clamp, which can be selected accordingly as needed. The signals generated by the temperature sensor and the magnetic induction element are transmitted to the digital display meter and other equipment through the transmission module.

[0011] As an improvement, the magnetic element swings with the knob and switches between a low-temperature position and a high-temperature position, and the swing angle is between 10° and 180°.

[0012] As an improvement, the rotation switching mechanism further comprises an angle positioning assembly provided on the half clamp. The angle positioning assembly comprises a limiting seat provided on the half clamp, a positioning piece movably provided on the limiting seat, and an elastic piece generating a force acting on the positioning piece in the direction of the knob.

[0059] The magnetic element 42 rotates with the rotation and switches between a low-temperature position and a high-temperature position, the magnetic induction element 41 senses different magnetic induction intensities in the low-temperature position and the high-temperature position, and thus different signals are sent to the wireless transmission module 32.

[0060] In this embodiment, the pin shaft 1 is sleeved with a torsion spring 10, and the two ends of the torsion spring 10 abut against the first half clamp 21 and the second half clamp 22 respectively.

[0061] In this embodiment, the magnetic element 42 oscillates with the knob 5 and switches between the low-temperature position and the high-temperature position, and the oscillation angle is between 30° and 90°. More specifically, in this embodiment, the oscillation angle of the magnetic element 42 and the knob 5 is 45°. With the oscillation operation mode, it is more convenient and faster than the one-way rotation. Figure 1 In the high-temperature position, the knob 5 and the magnetic element 42 are in the high-temperature position where the magnetic induction element 41 senses the magnetic field, Figure 2 In the low-temperature position, the knob 5 and the magnetic element 42 are in the low-temperature position where the magnetic induction element 41 does not sense the magnetic field. The standard for not sensing can be below a certain threshold, which can not be completely not sensed.
