Description

Technical Field

[0001] This invention belongs to the field of temperature clip technology, specifically relating to a temperature clip that allows for rotating switching between high and low temperature modes. Background Technology

[0002] In the field of HVAC technology, temperature sensors (temperature clips being the most common form) are frequently used. These clips are attached to the pipe being tested to measure the temperature. Temperature clips are typically divided into high-temperature clips for detecting dew point temperature and low-temperature clips for detecting bubble point temperature. The clips also transmit the detected dew point or bubble point temperature to a digital display. Maintenance personnel compare the dew point and bubble point temperatures uploaded by the clips with the retrieved temperatures to determine the fault in the air conditioning system.

[0003] Currently, most high and low temperature detectors on the market are sold separately. Users need to purchase two detectors, a high-temperature detector and a low-temperature detector, respectively (each detector is paired with a digital display, which identifies whether the temperature is high or low; high temperature corresponds to dew point, and low temperature corresponds to bubble point), which is costly. Furthermore, users need to carry both detectors, which is inconvenient.

[0004] Therefore, it is necessary to implement high and low temperature detection and temperature type switching functions on the same temperature clamp. While temperature type switching (i.e., switching between dew point temperature and bubble point temperature sent to the digital display) can be achieved using toggle switches or buttons, these are all located on one half of the clamp, which is unsightly, the operating parts are small, and operation is inconvenient. Summary of the Invention

[0005] This invention addresses the shortcomings of existing high and low temperature mode switching structures in general-purpose heating temperature clips by providing a rotary switch for high and low temperature modes. The switch between sending high temperature detection signals and low temperature detection signals is achieved by rotating a knob, which is easier to operate than dials or buttons.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature clip that allows for rotating high and low temperature modes, the temperature clip comprising:

[0007] The temperature clamp body includes a pin, two clamp halves that rotate relative to the pin, a temperature sensor and a transmission module mounted on the clamp halves, the two clamp halves including a first clamp and a second clamp, and the temperature sensor and the transmission module are connected together.

[0008] The rotary switching mechanism includes a magnetic induction element fixed on the first half-clamp, a knob that rotates relative to the pin shaft, and a magnetic element linked to the knob. The magnetic induction element is connected to the transmission module, and the knob is exposed on both half-clamps.

[0009] The magnetic element rotates and switches between low-temperature and high-temperature positions. The magnetic induction intensity sensed by the magnetic induction element is different in the low-temperature and high-temperature positions, thus sending different signals to the transmission module.

[0010] This invention relates to a rotary temperature clip that switches between high and low temperature modes. The rotary switching mechanism includes a magnetic induction element and a magnetic element. The magnetic element rotates and switches between low and high temperature positions. The magnetic induction intensity sensed by the magnetic induction element differs between the low and high temperature positions, thus sending different signals to the transmission module. When the magnetic element is in different positions, it generates two different signals to distinguish between high and low temperatures. For example, when the magnetic element is in the low temperature position, it emits a low temperature signal, indicating that a low temperature (e.g., bubble point temperature) is being detected; when the magnetic element is in the high temperature position, it emits a high temperature signal, indicating that a high temperature (e.g., dew point temperature) is being detected. Switching between high and low temperature signals is achieved by rotating a knob located at the axial end of a pin. The knob can be relatively large for easy operation and a more aesthetically pleasing design. Compared to existing pin-shaft rotation technologies, the knob eliminates the need for a separate shaft, simplifying the rotation structure. The components can be mounted on either the first or second half-clamp, depending on the requirements. Signals generated by the temperature sensor and the magnetic induction element are transmitted to devices such as digital displays via the transmission module.

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

[0012] As an improvement, the rotary switching mechanism also includes an angle positioning component on the half clamp. The angle positioning component includes a limiting seat on the half clamp, a positioning element movably provided on the limiting seat, and a spring element that generates a force in the direction of the knob on the positioning element. The knob has a low-temperature position hole and a high-temperature position hole adapted to the positioning element.

[0013] As an improvement, the angle positioning component is disposed on the first half-clamp, the first half-clamp has an anti-rotation hole, and the limiting seat is located in the anti-rotation hole; and / or,

[0014] The positioning element is a steel ball; and / or,

[0015] The elastic element is a compression spring; and / or,

[0016] The knob has a groove connecting the low-temperature position hole and the high-temperature position hole; and / or,

[0017] The angle positioning component includes a glass ball screw and forms a positioning element and a spring element.

[0018] As an improvement, two limiting blocks are formed on the first half clamp, and the knob has a limiting part located between the two limiting blocks, with the two limiting blocks limiting the limiting part.

[0019] As an improvement, a mounting groove is provided in the limiting part, and the magnetic element is fixed in the mounting groove of the limiting part; and / or,

[0020] The limit seat is threadedly connected to the pin.

[0021] As an improvement, the rotary switching mechanism also includes a temperature indicator label on the limit seat. The temperature indicator label includes two different colored blocks corresponding to the low temperature position and the high temperature position. An observation hole corresponding to the temperature indicator label is opened on the knob.

[0022] As an improvement, the pin has a slot, and the knob is axially prevented from disengaging by a retaining spring in the slot. An anti-disengagement groove is formed on the knob, and the retaining spring is located within the groove. The rotary switching mechanism also includes a decorative cover that closes the anti-disengagement groove; and / or,

[0023] The knob is fitted onto the pin.

[0024] As an improvement, the temperature clip body also includes a battery, a power switch, a display screen, and a main control board. A first anti-detachment groove is formed on the first half-clamp, and the display screen and main control board are located in the first anti-detachment groove. The outer side of the first anti-detachment groove is closed by a screen cover, and the inner side of the second anti-detachment groove is closed by a cover plate. The cover plate is fixed to the first half-clamp by screws, and the cover plate and the first half-clamp are sealed by a sealing ring; and / or,

[0025] A second anti-detachment groove is formed on the second half-clamp, the battery is disposed in the second anti-detachment groove, the outside of the second anti-detachment groove is sealed by a battery cover, and the battery cover is fixed to the second half-clamp by screws; and / or,

[0026] The first half-clamp forms a mounting position for the sensing element, and the magnetic sensing element is located in the mounting position for the sensing element. The mounting position for the sensing element is filled with glue.

[0027] As an improvement, the transmission module can be a wireless transmission module or a wired transmission module; and / or,

[0028] Magnetic induction elements include Hall switches; magnetic elements include magnets.

[0029] The beneficial effects of the rotary switching high and low temperature mode temperature clip of the present invention are as follows: the magnetic element switches between a low temperature position where the magnetic induction element does not sense a magnetic field and a high temperature position where a magnetic field is sensed. When the magnetic element is in different positions, the magnetic induction element can generate two different signals to distinguish between high and low temperatures. For example, when the magnetic element is in the low temperature position, the magnetic induction element emits a low temperature signal, indicating that a low temperature (such as bubble point temperature) is being detected at this time. When the magnetic element is in the high temperature position, the magnetic induction element emits a high temperature signal, indicating that a high temperature (such as dew point temperature) is being detected at this time. The switching between high and low temperature signals is achieved by rotating the knob. The knob is located at the axial end of the pin shaft. The knob size can be relatively large, making it convenient to operate and also more aesthetically pleasing. The knob rotates relative to the pin shaft, eliminating the need for an additional rotating shaft. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0050] See Figures 1 to 11 The rotary temperature clip for switching between high and low temperature modes according to an embodiment of the present invention includes:

[0051] The temperature clamp body includes a pin, two clamp halves that rotate relative to the pin, a temperature sensor and a transmission module mounted on the clamp halves, the two clamp halves including a first clamp and a second clamp, and the temperature sensor and the transmission module are connected together.

[0052] The rotary switching mechanism includes a magnetic induction element fixed on the first half-clamp, a knob that rotates relative to the pin shaft, and a magnetic element linked to the knob. The magnetic induction element is connected to the transmission module, and the knob is exposed on both half-clamps.

[0053] The magnetic element rotates and switches between low-temperature and high-temperature positions. The magnetic induction intensity sensed by the magnetic induction element is different in the low-temperature and high-temperature positions, thus sending different signals to the transmission module.

[0054] The temperature clip of this invention, which allows for rotational switching between high and low temperature modes, has a rotational switching mechanism. This mechanism includes a magnetic induction element and a magnetic element. The magnetic element rotates and switches between low and high temperature positions. The magnetic induction intensity sensed by the magnetic induction element differs between the low and high temperature positions, thus sending different signals to the wireless transmission module. When the magnetic element is in different positions, it generates two different signals to distinguish between high and low temperatures. For example, when the magnetic element is in the low temperature position, it emits a low temperature signal, indicating that a low temperature (e.g., bubble point temperature) is being detected. When the magnetic element is in the high temperature position, it emits a high temperature signal, indicating that a high temperature (e.g., dew point temperature) is being detected. The switching between high and low temperature signals is achieved by rotating a knob located at the axial end of a pin. The knob can be relatively large for easy operation and a more aesthetically pleasing appearance. The knob rotates directly relative to the pin, eliminating the need for an additional shaft for knob rotation.

[0055] Example 1

[0056] See Figures 1 to 11 The rotary temperature clip for switching between high and low temperature modes according to an embodiment of the present invention includes:

[0057] Temperature clamp body 01 includes a pin 1, two half-clamps that rotate relative to the pin 1, a temperature sensor 31, a wireless transmission module 32 and a battery 36 disposed on the half-clamps, and the two half-clamps include a first half-clamp 21 and a second half-clamp 22.

[0058] The rotary switching mechanism 02 includes a magnetic induction element 41 fixed on the first half clamp 21, a knob 5 that rotates relative to the pin 1, and a magnetic element 42 fixed on the knob 5. The magnetic induction element 41 is connected to the wireless transmission module 32.

[0059] The magnetic element 42 rotates and switches between low temperature and high temperature positions. The magnetic induction intensity sensed by the magnetic induction element 41 is different in the low temperature and high temperature positions, thereby sending different signals to the wireless transmission module 32.

[0060] In this embodiment, a torsion spring 10 is sleeved on the pin 1, 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 swings with the knob 5 and switches between a low-temperature position and a high-temperature position, with an swing angle between 30° and 90°. More specifically, in this embodiment, the swing angle of the magnetic element 42 and the knob 5 is 45°. This swinging operation is more convenient and faster than unidirectional rotation. Figure 1 In the middle, knob 5 and magnetic element 42 are in the high-temperature position where magnetic induction element 41 senses the magnetic field. Figure 2 In the middle, knob 5 and magnetic element 42 are in a low-temperature position where magnetic induction element 41 does not sense a magnetic field. The standard for not sensing is below a certain threshold, but it does not have to be completely unsensitized.

[0062] In this embodiment, the knob 5 has a shaft hole 51, through which the pin 1 passes, and the knob 5 swings around the pin 1.

[0063] In this embodiment, the rotation switching mechanism 02 also includes an angle positioning component 6 disposed on the first half clamp 21. The angle positioning component 6 positions the angle of the knob 5 (and also positions the magnetic element 42), so that the position of the knob 5 can be reliably maintained when there is no external force.

[0064] In this embodiment, the angle positioning component 6 includes a limiting seat 61 disposed on the first half clamp 21, a positioning member 62 disposed on the limiting seat 61, and an elastic member 63 that generates a force in the direction of the knob 5 on the positioning member 62. The knob 5 has a low-temperature position hole and a high-temperature position hole adapted to the positioning member 62.

[0065] In this embodiment, the first half-clamp 21 has an anti-rotation hole 211, and the limiting seat 61 is located in the anti-rotation hole 211. The limiting seat 61 has an anti-rotation part 611. Both the anti-rotation hole 211 and the anti-rotation part 611 are rectangular. The anti-rotation part 611 has a hole for the pin shaft 1 to pass through.

[0066] In this embodiment, the positioning element 62 is a steel ball. The spherical shape of the positioning element 62 allows for relatively easy movement. The use of a hard material such as steel for the positioning element 62 ensures a long service life.

[0067] In this embodiment, the elastic element 63 is a compression spring, which can provide reliable elastic force. A spring groove 612 is formed on the limiting seat 61, and the compression spring is located in the spring groove 612.

[0068] In other embodiments, a ball screw is installed on the limiting seat 61, forming a positioning element 62 and a spring element 63, so that the positioning element 62 will not fall off when the knob 5 is disassembled or assembled.

[0069] In this embodiment, a groove 55 is provided on the knob 5 to connect the low-temperature position hole and the high-temperature position hole. By providing the groove 55, the compression spring of the knob 5 is compressed to a smaller extent during the swinging process, making the swinging of the knob 5 less strenuous. Both the low-temperature position hole and the high-temperature position hole are spherical holes with spherical bottom walls. The cross-section of the groove 55 is arc-shaped.

[0070] In this embodiment, two limiting blocks 212 are formed on the first half-clamp 21, and the knob 5 has a limiting part 56. The two limiting blocks 212 limit the limiting part 56 to prevent the knob 5 from exceeding the limit during swing. When the limiting part 56 of the knob 5 contacts the two limiting blocks 212 on the first half-clamp 21, the positioning member 62 also reaches the low temperature position hole or the high temperature position hole. A thinning groove 213 is formed between the two limiting blocks 212 of the first half-clamp 21.

[0071] In this embodiment, the limiting part 56 has a mounting groove 57, and the magnetic element 42 is fixed in the mounting groove 57 of the limiting part 56. In other embodiments, the magnetic element 42 may not be fixed in the limiting part 56, but may be formed as a separate mounting part on the knob 5.

[0072] In this embodiment, the rotary switching mechanism 02 further includes a temperature indicator label 7 disposed on the limiting seat 61. The temperature indicator label 7 includes two segments of different colors corresponding to the low temperature position and the high temperature position. An observation hole 58 corresponding to the temperature indicator label 7 is opened on the knob 5. Usually, the segment corresponding to the low temperature is blue, and the segment corresponding to the high temperature is red. A label groove 613 is formed on the limiting seat 61, and the temperature indicator label 7 is located in the label groove 613. The limiting seat 61 has an indicator portion with an axial dimension larger than that of the anti-rotation portion 611. The label groove 613 is formed on the indicator portion, thereby allowing the temperature indicator label 7 to be closer to the observation hole 58 of the knob 5 for easier observation.

[0073] In this embodiment, the pin 1 has a slot 11, and the knob 5 is prevented from axially disengaging by a retaining spring 81 in the slot 11. An anti-disengagement groove 52 is formed on the knob 5, and the retaining spring 81 is located in the anti-disengagement groove 52. The pin 1 has a cap and a shaft, and the shaft has multiple steps.

[0074] In this embodiment, the rotary switching mechanism 02 further includes a decorative cover 82 that closes the anti-detachment groove 52. The retaining spring 81 and the decorative cover 82 form an anti-detachment decorative assembly 8. The knob 5 has a decorative groove 59, and the decorative cover 82 is located in the decorative groove 59, and the decorative cover 82 does not protrude outward from the knob 5.

[0075] In this embodiment, the magnetic sensing element 41 includes a Hall switch; the magnetic element 42 includes a magnet. A sensing element mounting position 215 is formed on the first half-clamp 21, and the Hall switch is located in the sensing element mounting position 215. The Hall switch is a unipolar Hall switch, which defaults to a low-temperature mode when not connected and switches to a high-temperature mode when connected.

[0076] In this embodiment, the temperature clamp body 01 also includes a power switch 35, a display screen 34, and a main control board 33. A first anti-detachment groove 52 is formed on the first half-clamp 21. The display screen 34 and the main control board 33 are located in the first anti-detachment groove 52. The outer side of the first anti-detachment groove 52 is closed by a screen cover 91, and the inner side of the second anti-detachment groove 52 is closed by a cover plate 92. The cover plate 92 is fixed to the first half-clamp 21 by screws, and the cover plate 92 and the first half-clamp 21 are sealed by a sealing ring 93. By setting the display screen 34 and the main control board 33, different modes can be displayed on the display screen 34 to further prevent errors. The main control board 33 and the display screen 34 are reliably sealed. The screen cover 91, the cover plate 92, the sealing ring 93, and the battery cover 36 form a closed assembly 9. The temperature sensor 31, the wireless transmission module 32, the main control board 33, the display screen 34, the power switch 35, and the battery 36 form an electronic assembly 3. By setting the main control board 33, in addition to displaying information on the display screen 34, it can also process the signals of the temperature sensor 31 and the magnetic induction element 41 to enhance adaptability.

[0077] In this embodiment, a second anti-detachment groove 52 is formed on the second half-clamp 22, and the battery 36 is disposed in the second anti-detachment groove 52. The outer side of the second anti-detachment groove 52 is sealed by the battery 36 cover, and the battery 36 cover is fixed to the second half-clamp 22 by screws. The battery 36 is reliably sealed.

[0078] In this embodiment, an operation indicator mark LOW-HIGH is also formed on the first half-clamp 21. In other embodiments, an indicator mark LH may also be formed on the knob 5.

[0079] In other embodiments, the wireless transmission module 32 can also be replaced by a cable. The temperature sensor 31 and the magnetic induction element 41 are both connected to devices such as digital displays via cables, and power is supplied to the temperature sensor 31 and the magnetic induction element 41 via cables, thus eliminating the need for a battery 36.

[0080] The beneficial effect of the rotating high and low temperature mode switching temperature clip in Embodiment 1 of the present invention is that the magnetic element 42 switches between a low temperature position where the magnetic induction element 41 does not sense a magnetic field and a high temperature position where a magnetic field is sensed. When the magnetic element 42 is in different positions, the magnetic induction element 41 can generate two different signals to distinguish between high and low temperatures. For example, when the magnetic element 42 is in the low temperature position, the magnetic induction element 41 emits a low temperature signal, indicating that the temperature being detected is low (such as the bubble point temperature). When the magnetic element 42 is in the high temperature position, the magnetic induction element 41 emits a high temperature signal, indicating that the temperature being detected is high. The high temperature (such as dew point temperature) is controlled by rotating knob 5 to switch between high and low temperature signals. Knob 5 is located at the axial end of pin 1. Knob 5 can be relatively large, making it easy to operate and aesthetically pleasing. Compared to the existing pin 1 rotation in the prior art, knob 5 does not require a separate shaft for knob 5 rotation, making the rotation structure of knob 5 simpler. Knob 5 swings, making operation convenient. It has a positioning structure, so knob 5 can reliably remain in the desired position when there is no external force. It has a limit structure to prevent knob 5 from exceeding the limit. It has a temperature indicator label 7, which can be used to observe the current mode.

[0081] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
