A mounting device for a temperature sensor

Abstract

This utility model discloses a fixing device for a temperature sensor, including a mounting base and a rotating base. The mounting base has a mounting groove, and a first anti-rotation structure is provided in the mounting groove. The rotating base has a connecting part, and the rotating base is rotatably connected to the mounting groove through the connecting part. The connecting part rotates when the rotating base is subjected to force to guide the rotation of the rotating base. The connecting part has a second anti-rotation structure, which cooperates with the first anti-rotation structure after the rotating base rotates to restrict the rotational movement of the rotating base. In use, the temperature sensor is installed in the rotating base. Since the rotating base is rotatably connected to the mounting groove of the mounting base through the connecting part, when it is necessary to adjust the installation angle of the temperature sensor, only an external force needs to be applied to the rotating base to drive the connecting part to rotate circumferentially along the mounting groove, thereby driving the temperature sensor to adjust its angle synchronously. This allows the temperature sensor to flexibly adjust its angle after installation to adapt to the spatial layout of different models and diverse usage scenarios.

Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a mounting device for a temperature sensor. Background Technology

[0002] In the air conditioning and heat pump industry, the mounting method of the ambient temperature sensor (referred to as "ambient temperature probe") is crucial to temperature measurement accuracy and equipment compatibility. Existing mounting solutions mainly include: high-temperature weather-resistant cable ties, box-type flip-top devices, or a combination of a simple sheet metal bracket and a box-type flip-top device. However, these methods use a rigid, integrated structure with no circumferential adjustment freedom, resulting in the angle of the ambient temperature probe being unadjustable after installation. Due to significant differences in the internal structure of air conditioning heat pumps of different power and models, the ambient temperature probe needs to be adjusted to match the model's installation position. The fixed angle is prone to measurement deviations due to component obstruction or excessive proximity to the heat source, and newly developed models are difficult to integrate with existing mounting components, resulting in extremely poor versatility. Therefore, there is an urgent need for an adjustable and versatile ambient temperature probe fixing device to solve the above problems. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, the present invention provides a fixing device for a temperature sensor, wherein the rotating seat for mounting the temperature sensor can rotate relative to the mounting seat, so that the temperature sensor can still be flexibly adjusted in angle after installation, thereby adapting to the spatial layout of different models and diverse usage scenarios, effectively solving the problem of poor adaptability caused by the non-adjustable angle of traditional fixing methods.

[0004] The technical solution adopted by this utility model to solve its problem is: A device for fixing a temperature sensor, comprising: Mounting base, the mounting base is provided with a mounting groove, and a first anti-rotation structure is provided in the mounting groove; A rotating seat is provided with a connecting part, and the rotating seat is rotatably connected to the mounting groove through the connecting part. The connecting part is used to rotate when the rotating seat is subjected to force, so as to guide the rotating seat to rotate. The connecting part is provided with a second anti-rotation structure, which is used to cooperate with the first anti-rotation structure to prevent the rotation of the rotating seat after the rotating seat rotates, so as to limit the rotational movement of the rotating seat.

[0005] Furthermore, the first anti-rotation structure includes a plurality of ratchet teeth, which are distributed circumferentially along the mounting groove; the second anti-rotation structure includes an elastic paddle, which is used to slide and engage with the ratchet teeth when the rotating seat is subjected to force, so as to guide the rotating seat to rotate, and the elastic paddle is used to abut against one of the ratchet teeth after the rotating seat rotates, so as to restrict the rotational movement of the rotating seat.

[0006] Furthermore, the ratchet is provided with a first guide slope, and the elastic paddle is provided with a second guide slope. The second guide slope is used to slide and engage with the first guide slope when force is applied, so as to guide the elastic paddle to slide.

[0007] Furthermore, the connecting part includes a connecting ring with an installation notch, and the elastic paddle is installed in the installation notch and spaced apart from the side wall of the installation notch.

[0008] Furthermore, the bottom of the rotating seat is provided with a first snap-fit ​​part, the first snap-fit ​​part includes two spaced snap-fit ​​arms, the connecting ring is provided with a first snap-fit ​​hole, the mounting seat is provided with a second snap-fit ​​hole, the second snap-fit ​​hole is correspondingly arranged with the first snap-fit ​​hole, and the two snap-fit ​​arms are used to slide and engage with the inner walls of the first snap-fit ​​hole and the second snap-fit ​​hole when subjected to force, so as to guide the first snap-fit ​​part to pass through the first snap-fit ​​hole and the second snap-fit ​​hole in sequence.

[0009] Furthermore, the rotating base includes a first housing and a second housing, the first housing and the second housing being rotatably connected, the first housing being used to cover or open the second housing during rotation; after the first housing and the second housing are connected, a mounting cavity is formed, the mounting cavity being used to install a temperature sensor; the second housing is provided with a mounting hole, the connecting part is provided with a connecting post, and the connecting post passes through the mounting hole.

[0010] Furthermore, the second housing is provided with a sealing boss, which extends along the periphery of the second housing and is used to abut against the inner wall of the first housing when the first housing covers the second housing.

[0011] Furthermore, the second housing is provided with limiting protrusions at both ends, and the two limiting protrusions are symmetrically distributed at both ends of the second housing. The limiting protrusions are connected to the sealing boss, and the limiting protrusions abut against the inner wall of the first housing.

[0012] Furthermore, the second housing is provided with drainage holes at both ends, and the drainage holes penetrate the second housing.

[0013] Furthermore, the mounting base is provided with a connecting arm, and the connecting arm is provided with a connecting hole. The connecting hole includes a first hole segment and a second hole segment, and the second hole segment is perpendicularly connected to and passes through the first hole segment.

[0014] In summary, the temperature sensor fixing device provided by this utility model has the following technical advantages: In use, the temperature sensor is first installed in the rotating base. Since the rotating base is rotatably connected to the mounting slot of the mounting base via a connecting part, when the installation angle of the temperature sensor needs to be adjusted, only an external force needs to be applied to the rotating base to drive the connecting part to rotate circumferentially along the mounting slot, thereby synchronously adjusting the angle of the temperature sensor. Thus, the temperature sensor can still flexibly change its angle after installation, adapting to the spatial layout of different models and diverse usage scenarios, effectively solving the problem of poor adaptability caused by the non-adjustable angle in traditional fixing methods. In addition, when the rotating seat rotates to the appropriate angle, the first anti-rotation structure in the mounting groove and the second anti-rotation structure on the connecting part will form an anti-rotation fit, thereby restricting the rotational movement of the rotating seat and fixing the rotating seat firmly in the designated position. This ensures that the temperature sensor can be flexibly adjusted after installation and remain stable after adjustment, thus guaranteeing the reliability of the temperature detection process.

[0022] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0023] See Figures 1 to 8 This utility model discloses a fixing device for a temperature sensor, including a mounting base 10 and a rotating base 20. The mounting base 10 is provided with a mounting groove 11, and a first anti-rotation structure 12 is provided in the mounting groove 11. The rotating base 20 is provided with a connecting part 30, and the rotating base 20 is rotatably connected to the mounting groove 11 through the connecting part 30. The connecting part 30 rotates when the rotating base 20 is subjected to force, so as to guide the rotating base 20 to rotate. The connecting part 30 is provided with a second anti-rotation structure 32, which cooperates with the first anti-rotation structure 12 to prevent rotation after the rotating base 20 rotates, so as to restrict the rotational movement of the rotating base 20.

[0024] Based on the above structure, during assembly, the temperature sensor 40 or other parts requiring angle adjustment are installed on the rotating base 20. The rotating base 20 is then rotatably connected to the mounting groove 11 via the connecting part 30. Subsequently, the mounting base 10 is connected to an external structure (e.g., the heat exchanger of an air conditioning heat pump). If, after installation, parts inside the rotating base 20 are obstructed by fins, pipes, or other structures due to improper angle, the user can apply external force to the rotating base 20, driving the connecting part 30 to rotate circumferentially along the mounting groove 11. This allows the rotating base 20 to rotate and adjust its angle, thereby synchronously adjusting the angle of the parts inside the rotating base 20. In this way, the installation position of parts inside the rotating base 20 (such as the temperature sensor 40) can be adjusted in real time according to changes in the scene or space, adapting to the spatial layout of different models and diverse usage scenarios. This effectively solves the problem of poor adaptability caused by the non-adjustable angle in traditional fixing methods.

[0025] When the rotating seat 20 rotates to a suitable angle, the first anti-rotation structure 12 in the mounting groove 11 and the second anti-rotation structure 32 on the connecting part 30 will form an anti-rotation fit, restricting the rotating seat 20 from continuing to rotate, so that the rotating seat 20 is firmly fixed in the designated position, allowing the rotating seat 20 to be flexibly adjusted after installation and to remain stable after adjustment, ensuring the reliability of the internal structure of the rotating seat 20 during operation.

[0026] It should be noted that, in this embodiment, the first anti-rotation structure 12 can be configured as multiple ratchet structures spaced circumferentially along the mounting groove 11, each ratchet structure having an inclined surface facing the rotation direction and a vertical stop surface facing away from the rotation direction; the second anti-rotation structure 32 can be configured as an elastic lever on the connecting part 30, the end of which has a protrusion adapted to the vertical stop surface of the ratchet structure. When the rotating seat 20 is subjected to force and rotates, the protrusion of the elastic lever will slide along the inclined surface of the ratchet structure, and the elastic lever will pass over the current ratchet structure due to elastic deformation, thus achieving rotation; when it rotates to the target angle, the protrusion of the elastic lever will reset under its own elastic force and closely abut against the vertical stop surface of the corresponding ratchet structure. Since the vertical stop surface cannot slide relative to each other, the ratchet structure and the elastic lever form a one-way lock, which can restrict the reverse rotation of the rotating seat 20, thereby achieving angle fixation.

[0027] Of course, in the above embodiments, the second anti-rotation structure 32 can also be a pawl or a paddle structure provided on the connecting part 30, which can also achieve the above anti-rotation effect.

[0028] In addition, the first anti-rotation structure 12 can also be configured as multiple positioning holes evenly distributed circumferentially on the inner wall of the mounting groove 11, and the second anti-rotation structure 32 can be configured as an elastic pin on the connecting part 30, with a retractable spherical protrusion at its end, and the diameter of the protrusion matching the diameter of the positioning hole. When the angle needs to be adjusted, the user applies an external force to the rotating seat 20 to drive it to rotate. During the process, the spherical protrusion of the elastic pin is squeezed and contracted by the inner wall of the mounting groove 11, and rotates synchronously with the connecting part 30. When the target angle is reached, the spherical protrusion aligns with a certain positioning hole, pops out under the action of elastic force and embeds into the positioning hole. At this time, the pin and the positioning hole form a rigid engagement, and the mechanical limitation of the hole and the protrusion prevents the connecting part 30 from continuing to rotate, thereby locking the angle of the rotating seat 20.

[0029] More specifically, in this embodiment, the connecting part 30 can be a columnar or ring-shaped structure integrally formed on the bottom of the rotating seat 20 and matching the contour of the mounting groove 11; or it can be a columnar or ring-shaped structure fixed to the bottom of the rotating seat 20 by connecting parts (such as bolts, buckles 211, etc.). Both forms can form a suitable rotational fit with the mounting groove 11, and the specific form can be selected according to actual assembly requirements, processing technology, etc.

[0030] Furthermore, the first anti-rotation structure 12 includes a plurality of ratchet teeth 121, which are distributed circumferentially along the mounting groove 11. The second anti-rotation structure 32 includes an elastic paddle 321, which slides with the ratchet teeth 121 when the rotating seat 20 is subjected to force, so as to guide the rotating seat 20 to rotate. After the rotating seat 20 rotates, the elastic paddle 321 abuts against one of the ratchet teeth 121 to limit the rotational movement of the rotating seat 20.

[0031] Specifically, when the installation angle of the rotating seat 20 needs to be adjusted, the user applies a circumferential external force to the rotating seat 20, and the connecting part 30 drives the elastic lever 321 to rotate synchronously with the rotating seat 20. At this time, the end of the elastic lever 321 away from the connecting part 30 will contact the inclined guide surface on the ratchet 121, and be compressed by the inclined surface to produce elastic deformation (such as bending inward towards the connecting part 30), and slide smoothly along the inclined surface until it passes the current ratchet 121. As the rotation continues, the elastic lever 321 will sequentially compress and deform with the subsequent ratchet 121 and slide past it in a cyclical action until the rotating seat 20 rotates to the appropriate angle.

[0032] When the rotating seat 20 rotates to the target angle, the user can stop applying external force. At this time, the end of the elastic lever 321 away from the connecting part 30 returns to its original position under its own elastic restoring force, and closely abuts against the vertical stop surface of the corresponding ratchet 121. Since the contact direction between the vertical stop surface and the elastic lever 321 is perpendicular to the rotation direction, relative sliding cannot occur, thus forming a rigid limit, preventing the rotating seat 20 from rotating in the opposite direction, and achieving angle locking.

[0033] Multiple ratchet teeth 121 distributed circumferentially within the mounting slot 11 form angle adjustment positions. Combined with the sliding of the elastic lever 321, the angle of the rotating seat 20 can be adjusted and positioned, thus easily aligning the temperature sensor 40 with the optimal detection position (such as avoiding obstructions such as pipes and fins). This solves the problem of "over-adjustment" or "under-adjustment" in traditional gearless structures and improves the accuracy of angle adjustment.

[0034] Furthermore, the ratchet 121 is provided with a first guide slope 1211, and the elastic paddle 321 is provided with a second guide slope 3211. The second guide slope 3211 is used to slide and engage with the first guide slope 1211 when subjected to force, so as to guide the elastic paddle 321 to slide.

[0035] Specifically, when the user applies a circumferential external force to the rotating seat 20, the connecting part 30 drives the elastic paddle 321 to rotate synchronously with the rotating seat 20. At this time, the second guide slope 3211 of the elastic paddle 321 will first contact the first guide slope 1211 of the ratchet 121. Since the inclination angles of the two slopes are matched, the second guide slope 3211 will slide naturally along the contour of the first guide slope 1211. During the sliding process, the first guide slope 1211 generates a lateral component force on the second guide slope 3211 through the slope contact. This component force will drive the elastic paddle 321 to undergo elastic deformation (rather than rigid collision) towards the inside of the connecting part 30. As the rotation continues, the two slopes always remain in contact, and the second guide slope 3211 gradually climbs up to the top of the ratchet 121 along the first guide slope 1211, completing a single ratchet overrun action; then the elastic paddle 321 quickly returns to its original position under its own elastic force, preparing for the next ratchet overrun. This allows the connecting part 30 to rotate smoothly without jamming when under force, improving the smoothness of operation when adjusting the angle. More specifically, in this embodiment, the connecting part 30 includes a connecting ring 31. During assembly, a mounting notch 311 is provided on the connecting ring 31, and the elastic lever 321 is installed in the mounting notch 311. At the same time, the elastic lever 321 is spaced apart from the side wall of the mounting notch 311, providing a deformation buffer area for the elastic lever 321. When the elastic lever 321 contacts the guide slope of the ratchet 121 and is subjected to force, it can freely bend and deform towards the inside of the mounting notch 311 (instead of being blocked by the side wall), allowing the elastic lever 321 to smoothly pass over the ratchet 121. During reset, the space prevents the lever from rubbing against or getting stuck with the side wall. This improves the smoothness of the angle adjustment process.

[0036] It should be noted that the connecting ring 31 can be detachably connected to the bottom of the rotating seat 20 by means of a clip or screw bolt. In this way, if the connecting ring 31 or the elastic lever 321 is worn and needs to be replaced, only the connecting ring 31 needs to be removed and replaced, which is convenient for maintenance.

[0037] Furthermore, the bottom of the rotating seat 20 is provided with a first snap-fit ​​part 24, which includes two spaced snap-fit ​​arms 241. The connecting ring 31 is provided with a first snap-fit ​​hole 33, and the mounting seat 10 is provided with a second snap-fit ​​hole 13. The second snap-fit ​​hole 13 is correspondingly arranged with the first snap-fit ​​hole 33. When the two snap-fit ​​arms 241 are subjected to force, they slide and cooperate with the inner walls of the first snap-fit ​​hole 33 and the second snap-fit ​​hole 13 to guide the first snap-fit ​​part 24 to pass through the first snap-fit ​​hole 33 and the second snap-fit ​​hole 13 in sequence.

[0038] Specifically, during assembly, the two snap-fit ​​arms 241 at the bottom of the rotating seat 20 are aligned with the first snap-fit ​​hole 33 of the connecting ring 31. The user then applies axial pressure to the rotating seat 20. At this time, the front ends of the two snap-fit ​​arms 241 first contact the inner wall of the first snap-fit ​​hole 33. Because the two snap-fit ​​arms 241 are elastic and the initial distance is slightly larger than the distance between the inner walls of the first snap-fit ​​hole 33, after contact, they are slightly deformed inward by the pressure of the hole wall, reducing the distance to fit the hole diameter. Simultaneously, the outer wall of the snap-fit ​​arm 241 forms a sliding fit with the hole wall, smoothly extending along the axial direction of the hole to pass through the connecting ring 31. Afterward, the two snap-fit ​​arms 241 continue to be pushed by axial force, and their front ends align with the second snap-fit ​​hole 13 of the mounting seat 10. The above sliding fit process is repeated. The snap-fit ​​arms 241 are kept deformed by the pressure of the inner wall of the second snap-fit ​​hole 13, continuing to slide along the hole wall until they completely pass through the second snap-fit ​​hole 13.

[0039] After the two snap-fit ​​arms 241 have completely passed through the first snap-fit ​​hole 33 and the second snap-fit ​​hole 13, the snap-fit ​​arms 241 are released from the hole wall constraint and reset under their own elasticity, and the spacing is restored to the initial state. At this time, the ends of the two snap-fit ​​arms 241 will abut against the bottom of the mounting base 10, and the axial fixation is completed.

[0040] Thus, the entire assembly process can be completed by the user with only a small axial force, without the need for tools or forceful hammering, making the operation convenient and efficient. At the same time, the symmetrical distribution of the two snap-fit ​​arms 241 makes the force more balanced, reducing the jamming problem that may be caused by unilateral force, making the threading process easier and smoother.

[0041] Furthermore, the rotating base 20 includes a first housing 21 and a second housing 22, which are rotatably connected. When the first housing 21 rotates, it covers or opens the second housing 22. After the first housing 21 and the second housing 22 are connected, a mounting cavity 23 is formed. The mounting cavity 23 is used to install the temperature sensor 40. The second housing 22 is provided with a mounting hole 221, and the connecting part 30 is provided with a connecting post 34, which passes through the mounting hole 221.

[0042] Specifically, the first housing 21 and the second housing 22 can be rotatably connected by a hinge 25 or a rotating shaft. When the temperature sensor 40 needs to be installed, the user can apply external force to the first housing 21 to make the first housing 21 rotate until the second housing 22 is opened. Then, the temperature sensor 40 is placed in the preset position of the second housing 22 (such as at the limiting piece 225 on the second housing 22, and the sensor is fixed by the limiting piece 225). Then, the first housing 21 is rotated in the opposite direction to make it snap and seal with the second housing 22. The two housings are fixed by the buckle 211, magnetic attraction and other auxiliary structures. At this time, the temperature sensor 40 is completely wrapped in the mounting cavity 23. Finally, the mounting hole 221 at the bottom of the second housing 22 is aligned with the connecting post 34, so that the connecting post 34 passes through the mounting hole 221, and the fixing of the rotating seat 20 and the connecting part 30 is completed.

[0043] When the temperature sensor 40 needs to be inspected or replaced, the sensor can be removed simply by opening the first housing 21. There is no need to disassemble the overall connection between the rotating base 20, the connecting part 30, and the mounting base 10, making the operation flexible.

[0044] The enclosed mounting cavity 23 formed by the fastening of the first housing 21 and the second housing 22 provides physical protection for the temperature sensor 40, thereby reducing the contamination of the temperature sensor 40 by dust, water vapor, oil and other pollutants during equipment operation, which would affect its temperature measurement accuracy. In addition, it can also buffer external vibrations and impacts (such as pipeline vibrations during equipment operation), reducing the risk of the temperature sensor 40 being damaged by bumps.

[0045] It should be noted that in this embodiment, the first housing 21 and the second housing 22 can be detachably connected through a snap-fit ​​structure. For example, the first housing 21 has an outwardly protruding buckle 211 on its edge, and the corresponding position of the second housing 22 has a snap-fit ​​notch 226 adapted to the buckle 211. When the first housing 21 is rotated to snap into the second housing 22, the buckle 211 will naturally align with the snap-fit ​​notch 226 as the housing rotates and snap into the notch, achieving a stable connection between the two. When separating, simply apply a reverse pulling force to the first housing 21 to disengage the buckle 211 from the snap-fit ​​notch 226 to open the housing. This operation is convenient and suitable for repeated opening and closing.

[0046] Furthermore, the second housing 22 is provided with a sealing boss 222, which extends along the periphery of the second housing 22 and is used to abut against the inner wall of the first housing 21 when the first housing 21 covers the second housing 22.

[0047] Specifically, when the first housing 21 covers the second housing 22, the sealing boss 222 abuts tightly against the inner wall of the first housing 21 along the periphery of the second housing 22, forming a raised sealing barrier at the junction of the two housings. Thus, if rainwater seeps in from the gap between the first housing 21 and the second housing 22, the water flow will be directly blocked by the raised sealing boss 222, making it difficult for the water to pass over the boss and enter the depths of the gap. At the same time, the tight fit between the sealing boss 222 and the inner wall of the first housing 21 shortens the possible path for water to seep in, ensuring that most of the water is blocked upon contact with the sealing boss 222 and cannot enter the interior of the second housing 22.

[0048] Therefore, by sealing the boss 222, the probability of water flowing into the interior of the rotating seat 20 through the connection gap is reduced, the risk of the temperature sensor 40 and related structures in the mounting cavity 23 being damaged by water ingress is reduced, and the waterproof protection performance of the rotating seat 20 is improved.

[0049] More specifically, the second housing 22 has limiting protrusions 223 at both ends, symmetrically distributed at both ends. The limiting protrusions 223 connect with the sealing boss 222 and abut against the inner wall of the first housing 21. When the first housing 21 rotates to cover the second housing 22, as the two housings gradually snap together, the limiting protrusions 223 at both ends of the second housing 22 will first contact the inner wall of the first housing 21. As the snapping force continues to be applied, the top surface of the limiting protrusions 223 fits tightly against the inner wall of the first housing 21, forming an axial limit through rigid abutment. At this time, the limiting protrusions 223 will generate a reverse supporting force on the first housing 21, which, together with the buckle 211 on the edge of the first housing 21 and the snap-fit ​​notch 226 on the second housing 22, locks the first housing 21, reducing the risk of the first housing 21 shifting or loosening and improving the overall stability of the rotating seat 20.

[0050] Furthermore, if a small amount of water accidentally seeps into the mounting cavity 23 through the gap between the first housing 21 and the second housing 22, the seeping water will naturally flow to the bottom of the second housing 22 (the lowest point of the mounting cavity 23) due to gravity, and collect at the drain holes 224 at both ends, and then quickly drain out of the housing through the holes. This drain holes 224 are used to drain the accumulated liquid, reducing the possibility of water accumulation in the mounting cavity 23.

[0051] Furthermore, the mounting base 10 is provided with a connecting arm 14, and the connecting arm 14 is provided with a connecting hole 141. The connecting hole 141 includes a first hole segment 1411 and a second hole segment 1412. The second hole segment 1412 is perpendicularly connected to and passes through the first hole segment 1411.

[0052] Specifically, after the rotating seat 20 and the mounting seat 10 are assembled, the entire fixing device needs to be fixed to the external structure via the connecting arm 14. At this time, the user can insert bolts or screws into the connecting hole 141. Since the connecting hole 141 includes a vertically penetrating first hole segment 1411 and a second hole segment 1412, the user can flexibly choose to insert the connecting piece into the first hole segment 1411 (for horizontal fixing) or the second hole segment 1412 (for vertical fixing) according to the installation orientation (horizontal or vertical) of the external structure and the required initial installation angle. This allows the connecting arm 14 to be compatible with external mounting structures in different directions, such as horizontal and vertical, without needing to replace the mounting seat 10 due to the orientation of the external threaded hole, thus improving the device's adaptability to diverse equipment structures.
