Description

Technical Field

[0001] The utility model relates to the field of air-conditioning temperature sensors, in particular to a temperature sensor for an outdoor unit of an air-conditioning. Background Art

[0002] The temperature sensor can accurately sense the outside temperature and transmit the sensed information to the main control board of the air conditioner. Through the intelligent control mode of the air conditioning system, it can automatically adjust the operating mode of the internal refrigeration system to ensure a more comfortable indoor environment. This function is especially important in hot summer or cold winter because it can help the air conditioning system understand the changes in outdoor temperature at any time and automatically adjust the cooling or heating function to ensure that the indoor temperature always remains within the appropriate range.

[0003] At present, the temperature sensors commonly equipped on air conditioner outdoor units are mainly used to monitor the external ambient temperature, thereby collecting key temperature data, which are crucial for optimizing the operating status of the air conditioner and improving work efficiency. However, such sensors are usually designed to be installed on the heat sink of the air conditioner outdoor unit, and their connection method mainly relies on the fixing buckle to engage with the ribs of the heat sink through stress deformation. However, in actual operation, due to inexperienced operators or improper force during installation, the structure of such fixing buckle is often easy to break, which not only affects the stability of the temperature sensor, but also greatly reduces the convenience of its installation. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a temperature sensor for an air-conditioning outdoor unit to solve the technical problem that the structural form of the fixed buckle is prone to breakage when an operator with no operating experience or applies a large force to the buckle during the installation process, thereby reducing the convenience of installing the temperature sensor.

[0005] To achieve the above object, the utility model provides the following technical solutions: a temperature sensor for an outdoor unit of an air conditioner, comprising a sensor body and a heat sink rib, wherein a sensor housing is disposed on the outside of the sensor body, a clamping mechanism is disposed on the back of the sensor housing, the clamping mechanism comprises a mounting frame, a mounting groove is disposed inside the mounting frame, a hook is disposed inside the mounting groove, a first oblique groove and a second oblique groove are disposed on the surface of the hook, a first pressing rod is disposed inside the first oblique groove, and a second pressing rod is disposed inside the second oblique groove;

[0006] A connecting piece is fixedly provided on the first and second pressing rods, a fixing block is provided on one side of the connecting piece close to the mounting groove, a mounting hole is provided inside the fixing block, and a pressure spring is provided inside the mounting hole.

[0007] By adopting the above technical solution, the traditional fixed structure clip is improved into a movable hook structure, which significantly reduces the pressure on the hook during installation. Since the hook is now movable, it is no longer necessary to force it in during installation as in the past, thereby greatly reducing the possibility of damage to the hook during installation.

[0008] Furthermore, two hooks are provided, and the two hooks are arranged in a mirror image.

[0009] By adopting the above technical solution, the two hooks are arranged in a mirror image manner, which significantly enhances the connection stability between the sensor and the heat sink ribs. Since there are two hooks acting at the same time, they can share the force together, reducing the risk of single-point force, thereby improving the stability of the overall structure.

[0010] Furthermore, the hook is engaged with the rib of the heat sink, and the hook is slidably connected with the installation frame through the installation groove.

[0011] By adopting the above technical solution, it is ensured that the sensor can be firmly mounted on the heat sink and is not easy to fall off or loosen. This snap-fit ​​method provides a stable connection, allowing the sensor to accurately monitor temperature data and ensure the normal operation of the air-conditioning system.

[0012] Furthermore, the inner walls of the first inclined groove and the second inclined groove are both inclined structures, and the inner walls of the first inclined groove and the second inclined groove are respectively in contact with the first pressing rod and the second pressing rod.

[0013] By adopting the above technical solution, the contact area between the inclined groove and the pressure rod is made larger, and the force points are dispersed, thereby reducing stress concentration and local wear, which helps to extend the service life of the engaging mechanism and improve its working stability.

[0014] Furthermore, a pressing rod is provided on one side of the connecting piece, and the pressing rod is used to provide a supporting point for the user to act on the connecting piece.

[0015] By adopting the above technical solution, the user can obtain a clear and stable supporting point, which enables the user to apply force to the connecting piece more accurately and effectively, thereby controlling the movement and engagement operation of the hook.

[0016] Furthermore, two ends of the pressure spring are respectively in contact with the inner walls of the mounting hole and the mounting groove to provide a clamping force between the clamping hook and the heat sink rib.

[0017] By adopting the above technical solution, the pressure spring can stably provide elastic force, and when the hook needs to be engaged with the rib of the heat sink, the elastic force of the pressure spring plays a key role.

[0018] Furthermore, a pressing piece is provided on the outer side of the connecting piece to limit the position of the connecting piece, and the pressing piece is fixedly connected to the mounting frame.

[0019] By adopting the above technical solution, the pressing piece can effectively limit the position of the connecting piece, preventing it from unnecessary movement or deviation during installation or use, thereby improving the stability and reliability of the overall structure.

[0020] Furthermore, the mounting groove is a rectangular structure, and the mounting frame and the sensor housing are an integrated structure.

[0021] By adopting the above technical solution, the movement of components such as hooks and connecting plates in the installation groove is more stable and accurate. The rectangular structure has clear boundaries and positioning, which effectively prevents the components from shaking or deviating from the predetermined position during the installation process, thereby improving the accuracy and efficiency of the installation.

[0022] Furthermore, the snap-fit ​​mechanism has two but not limited to two structural size forms, and the sensor housing and the sensor body are in a detachable structure.

[0023] By adopting the above technical solution, this flexibility enables the snap-fit ​​mechanism to adapt to heat sink ribs of different specifications and sizes. Whether it is facing different models of air-conditioning outdoor units or heat sinks of different designs, the snap-fit ​​mechanism can provide a suitable snap-fit ​​method, ensuring the wide applicability and convenience of sensor installation.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] 1. The utility model improves the traditional fixed structure buckle into a movable hook structure through a snap-fit ​​mechanism, which can significantly reduce the pressure on the hook during installation. Since the hook can now be moved, it is no longer necessary to force it into the heat sink rib during installation, thereby reducing the risk of damage to the hook due to excessive force during installation. At the same time, it is also beneficial to improve the structural strength of the snap-fit ​​between the hook and the heat sink rib. After installation, the hook can snap more tightly with the heat sink rib, thereby enhancing the connection stability between the sensor housing and the heat sink rib. This more stable connection not only improves the safety of the sensor, but also helps to extend its service life.

[0026] 2. The utility model provides a pressure piece, which is arranged on the outer side of the connecting piece to abut against the pressure piece, thereby effectively limiting the position movement of the connecting piece during the installation process, so that the installer can position the connecting piece more quickly and accurately, thereby improving the installation efficiency of the locking mechanism. At the same time, the position restriction of the connecting piece by the pressure piece also helps to reduce errors and adjustment time during the installation process. The installer does not need to repeatedly adjust the position of the connecting piece, but only needs to simply abut it against the pressure piece. This greatly simplifies the installation steps and improves the installation convenience of the locking mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0033] The following describes an embodiment of the utility model based on its overall structure.

[0034] Embodiment 1:

[0035] A temperature sensor for an outdoor unit of an air conditioner, such as Figure 1-Figure 4As shown, it includes a sensor body 2 and a heat sink rib 3, a sensor housing 1 is arranged on the outside of the sensor body 2, a clamping mechanism 4 is arranged on the back of the sensor housing 1, and the clamping mechanism 4 includes a mounting frame 401, a mounting groove 402 is arranged inside the mounting frame 401, a hook 403 is arranged inside the mounting groove 402, a first oblique groove 404 and a second oblique groove 405 are arranged on the surface of the hook 403, a first pressing rod 406 is arranged inside the first oblique groove 404, and a second pressing rod 407 is arranged inside the second oblique groove 405;

[0036] A connecting piece 408 is fixedly provided on the first pressure rod 406 and the second pressure rod 407, and a fixing block 410 is provided on one side of the connecting piece 408 close to the mounting groove 402. A mounting hole 411 is provided inside the fixing block 410, and a pressure spring 412 is provided inside the mounting hole 411. The traditional form of fixed structure buckle is improved into a movable hook 403 structure, which significantly reduces the pressure on the hook 403 during the installation process. Since the hook 403 is now movable, it is no longer necessary to force it into place during installation as in the past, thereby greatly reducing the possibility of damage to the hook 403 during the installation process. At the same time, it is also beneficial to improve the structural strength of the hook 403 and the heat sink rib 3. Since the hook 403 can be moved to the optimal position and then engaged with the heat sink rib 3, the engagement is tighter and not easy to loosen, thereby improving the stability and reliability of the sensor installation.

[0037] See also Figure 2 , Figure 3 , Figure 4 There are two hooks 403, which are arranged in a mirror image. The two hooks 403 are arranged in a mirror image, which significantly enhances the connection stability between the sensor and the heat sink rib 3. Since there are two hooks 403 acting at the same time, they can share the force together and reduce the risk of single-point force, thereby improving the stability of the overall structure. At the same time, this mirror image arrangement also helps to balance the force distribution of the sensor during installation. When installing or subjected to external force, the two hooks 403 can be evenly stressed to avoid damage or deformation caused by excessive force on a single point, further enhancing the durability and reliability of the sensor.

[0038] See also Figure 1 , Figure 2The hook 403 is engaged with the heat sink rib 3, and the hook 403 is slidably connected to the mounting frame 401 through the mounting groove 402, ensuring that the sensor can be firmly mounted on the heat sink and is not easy to fall off or loosen. This engaging method provides a stable connection, so that the sensor can accurately monitor temperature data and ensure the normal operation of the air-conditioning system. At the same time, the hook 403 is slidably connected to the mounting frame 401 through the mounting groove 402, making the installation process more flexible and convenient. The installer can adjust the position of the hook 403 as needed to adapt to heat sink ribs 3 of different specifications or shapes. This sliding connection also reduces stress concentration during the installation process, reduces the risk of damage to the hook 403, and increases the service life of the sensor.

[0039] See also Figure 1 , Figure 2 , Figure 3 The inner walls of the first inclined groove 404 and the second inclined groove 405 are both inclined structures, and the inner walls of the first inclined groove 404 and the second inclined groove 405 are respectively in contact with the first pressing rod 406 and the second pressing rod 407, so that the contact area between the inclined groove and the pressing rod is larger, and the force points are dispersed, thereby reducing stress concentration and local wear, which helps to extend the service life of the engaging mechanism 4 and improve its working stability. At the same time, this close matching relationship ensures the stability and accuracy of the hook 403 during the movement. When the pressing rods are subjected to pressure, they can slide smoothly along the inner wall of the inclined groove, thereby driving the hook 403 to perform reliable engaging or releasing operations.

[0040] See also Figure 1 , Figure 2 , Figure 3 A pressing rod 409 is provided on one side of the connecting piece 408. The pressing rod 409 is used to provide a support point for the user to apply action on the connecting piece 408. The user can obtain a clear and stable support point, which enables the user to apply force to the connecting piece 408 more accurately and effectively, thereby controlling the movement and engagement operation of the hook 403. At the same time, the existence of the pressing rod 409 also improves the comfort and convenience of the user's operation. It provides a part that is easy to reach and hold, so that the user can maintain stable control of the operation even under sweaty or wet conditions.

[0041] See also Figure 2 , Figure 3The two ends of the pressure spring 412 are respectively in contact with the inner walls of the mounting hole 411 and the mounting groove 402, so as to provide a clamping force between the hook 403 and the heat sink rib 3, so that the pressure spring 412 can stably provide elastic force. When the hook 403 needs to be clamped with the heat sink rib 3, the elastic force of the pressure spring 412 plays a key role. At the same time, the clamping between the hook 403 and the heat sink rib 3 is more firm and reliable. The continuous elastic force provided by the pressure spring 412 ensures that the hook 403 can maintain a tight clamping connection with the heat sink rib 3 even when subjected to vibration or external force, thereby improving the stability and reliability of the sensor installation.

[0042] Embodiment 2:

[0043] See also Figure 2 , Figure 4 A pressing piece 5 is provided on the outer side of the connecting piece 408 to limit the position of the connecting piece 408. The pressing piece 5 is fixedly connected to the mounting frame 401. The pressing piece 5 can effectively limit the position of the connecting piece 408 to prevent it from unnecessary movement or displacement during installation or use, thereby improving the stability and reliability of the overall structure. At the same time, the fixed connection between the pressing piece 5 and the mounting frame 401 further enhances the stability of the structure. This connection method ensures that the pressing piece 5 can always play an effective role and will not affect the position stability of the connecting piece 408 due to loosening or falling off.

[0044] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The mounting groove 402 is a rectangular structure, and the mounting frame 401 and the sensor housing 1 are an integrated structure, so that the movement of components such as the hook 403 and the connecting piece 408 in the mounting groove is more stable and accurate. The rectangular structure has clear boundaries and positioning, which effectively prevents the components from shaking or deviating from the predetermined position during the installation process, thereby improving the accuracy and efficiency of the installation. At the same time, the mounting frame 401 and the sensor housing 1 adopt an integrated structure, which significantly enhances the overall structural strength and stability, avoids structural failure problems caused by loose or broken connections between the mounting frame and the sensor housing, and ensures the safety and reliability of the sensor during use.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The snap-fit ​​mechanism 4 is of two but not limited to two structural size forms. The sensor housing 1 and the sensor body 2 are of a detachable structure. This flexibility enables the snap-fit ​​mechanism 4 to adapt to heat sink ribs 3 of different specifications and sizes. Whether it is facing different models of air-conditioning outdoor units or heat sinks of different designs, the snap-fit ​​mechanism 4 can provide a suitable snap-fit ​​method, ensuring the wide applicability and convenience of sensor installation. At the same time, the sensor housing 1 and the sensor body 2 adopt a detachable structure, which makes the maintenance and replacement of the sensor simpler and more efficient. When the sensor needs to be repaired or recalibrated, the staff can easily separate the housing from the body without disassembling or reinstalling the entire sensor, which not only saves time and labor costs, but also reduces the risk of sensor damage due to improper operation.

[0046] The implementation principle of the utility model is as follows: first, the pressing rod 409 is pressed to drive the connecting piece 408 to move in position by overcoming the elastic force of the pressure spring 412. At the same time, the second pressing rod 407 is used to abut against the inclined surface of the second inclined groove 405. As the second pressing rod 407 moves with the connecting piece 408, the two hooks 403 move toward each other. Subsequently, the hooks 403 are passed through the gaps of the heat sink ribs 3. Next, the pressing force on the pressing rod 409 is released, and the elastic force of the pressure spring 412 is used to The connection piece 408 is positioned and utilized, and the first pressing rod 406 exerts a pressing force on the first inclined groove 404, causing the two hooks 403 to move outward, and the hooks 403 are engaged with the corresponding heat sink ribs 3, completing the installation operation of the sensor housing 1, and improving the traditional fixed structure buckle to a movable hook 403 structure, thereby reducing the pressure on the hook 403 during the installation process and reducing the possibility of damage to the hook 403, while helping to improve the strength of the engagement structure with the heat sink ribs 3.
