Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner radiator installation, in particular to a self-locking elastic pressing plate for air conditioner radiator. BACKGROUND

[0002] In the installation and fixing process of air conditioner radiators, the traditional pressing plate structure used to fix the radiator components has many significant limitations, which seriously restricts the performance and stability of the air conditioning system.

[0003] Among them, the installation method of the traditional pressing plate is extremely simple and lacks an effective self-locking mechanism. During installation, the pressing plate and the radiator components are simply fixed by tightening the screws. However, during operation, the radiator is continuously affected by various complex factors. On the one hand, the vibration generated by the operation of air conditioner components such as compressors can be transmitted to the radiator through the system, causing the radiator to be in a state of continuous micro-vibration. On the other hand, the radiator will experience frequent temperature changes under different operating modes of the air conditioner, and the radiator components made of metal will deform due to thermal expansion and contraction.

[0004] Under the combined action of these factors, the fixing method relying solely on screw tightening is prone to problems. The screws will gradually loosen due to vibration, and the degree of loosening will continue to increase as the use time extends. Once the screws loosen, the fixing effect of the pressing plate on the radiator components will be greatly weakened, and the radiator components may shift. After the radiator components shift, their contact area and flow path with the air change, resulting in reduced heat dissipation efficiency and inability to effectively dissipate heat in a timely manner. This not only makes the cooling or heating effect of the air conditioner worse, affecting the user's experience, but also may trigger the protection mechanism due to system overheating, causing the air conditioner to frequently shut down and reducing the overall performance of the air conditioner. More seriously, in extreme cases, the displacement of the radiator components may cause safety hazards such as short circuits, threatening the safety of the user's person and property.

[0005] After the radiator components shift, the radiator cannot effectively transfer the heat absorbed from the refrigerant or heat-generating elements to the surrounding air, affecting the normal operation of the radiator. At the same time, the relative movement between the pressing plate and the radiator components also generates additional friction and stress, accelerating the wear and aging of the components. In the long run, the performance of the radiator components will gradually decline, and they may even be damaged, thereby shortening the service life of the air conditioner and increasing the user's maintenance costs and usage burden.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following will be further described in combination with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present application, and not all. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0026] Embodiment 1: Referring to Figures 1-8 The self-locking elastic pressing plate of the air conditioner radiator shown in the figure comprises a pressing plate body 1 and a screw for installing the pressing plate body 1, the screw comprising a screw rod 2 passing through the installation hole opened at the end of the pressing plate body 1 and a control column 3 fixedly arranged at the end of the screw rod 2; the pressing plate body 1 is provided with a positioning assembly.

[0027] When the pressing plate body 1 is installed, one end of the screw rod 2 passes through the installation hole and drives the screw rod 2 to rotate through the control column 3, drives the control column 3 and the part of the pressing plate body 1 below the control column 3 to move downward and deform, and the deformed pressing plate body 1 is fixed with the control column 3 through the positioning assembly.

[0028] The pressing plate body 1 is placed near the position where the air conditioner radiator component needs to be fixed. At this time, the pressing plate body 1 is in a natural undeformed state, and the parts of the positioning assembly are in the initial position before being matched. The screw rod 2 of the screw is inserted through the mounting hole in the end of the pressing plate body 1, and the screw is preliminarily connected with the pressing plate body 1. The control column 3 is located above the pressing plate body 1 to facilitate subsequent operation. Then the control column 3 is rotated by a tool or manually. Since the control column 3 is fixedly connected with the screw rod 2, the rotation of the control column 3 will drive the screw rod 2 to rotate together. With the rotation of the screw rod 2, under the action of the threaded connection between the screw rod 2 and the mounting position, the control column 3 and the part of the pressing plate body 1 located below the control column 3 will move downward, causing the pressing plate body 1 to elastically deform. This deformation is controllable, and according to the design requirements, the pressing plate body 1 will produce a certain bending or stretching, thereby generating a pre-tightening force on the radiator component. When the pressing plate body 1 deforms to an appropriate degree, the positioning assembly provided on the pressing plate body 1 fixes the deformed pressing plate body 1 and the control column 3.

[0029] The self-locking elastic pressing plate of this embodiment can realize the deformation and fixation of the pressing plate through the rotation of the control column 3, greatly simplifying the installation steps, reducing the time and labor cost required for installation, and improving the installation efficiency. The design of the positioning assembly enables the pressing plate body 1 to be quickly and accurately positioned at the specified position of the radiator component during installation. The self-locking mechanism forms a reliable connection mode through the deformation of the pressing plate body 1 and the fixation of the positioning assembly. Compared with the traditional fixation method relying only on screw tightening, this self-locking structure can better resist vibration and looseness, ensuring that the pressing plate remains in a stable fixed state for a long time after installation, reducing the need for reinstallation or maintenance due to insecure installation.

[0030] Embodiment 2: For the positioning assembly that fixes the position between the pressing plate body 1 and the control column 3, this embodiment provides a first positioning assembly solution.

[0031] As shown in Figure 1 and Figure 2 , the positioning assembly includes two positioning columns 6 symmetrically arranged on the top end face of the pressing plate body 1 relative to the mounting hole, and the bottom end side of the control column 3 is provided with a plurality of positioning grooves 5 matched with the side surface of the positioning column 6 in a circular array; when the control column 3 is deformed downward by the screw rod 2 for installing the pressing plate body 1, the top parts of the two positioning columns 6 are inserted into the positioning grooves 5 and close to each other, fixing the position between the control column 3 and the pressing plate body 1.

[0032] The clamping force has been generated, and the electronic device and the heat sink are reliably attached. Direct observation of the deformation of the pressing sheet can be performed, and the torque of the screwdriver does not need to be measured, and the phenomenon of loose clamping or excessive clamping will not occur. The positioning column 6 is arranged on the pressing plate body 1, and when the pressing plate body 1 is installed, the pressing plate body 1 will be concave and deformed downward, and the two positioning columns 6 on the top of the mounting hole will be close to each other. At this time, the two positioning columns 6 are arranged in the positioning groove 5 arranged on the bottom end side of the control column 3, so as to conveniently fix the position between the pressing plate body 1 and the control column 3, prevent the control column 3 from shaking or shifting relative to the pressing plate body 1 in the subsequent use process, and enhance the stability and reliability of the entire structure. The control column 3 can stably play its function, and the entire device can normally operate.

[0033] Embodiment 3: For the fixation of the position between the pressing plate body 1 and the control column 3 of the first positioning assembly in embodiment 2, the structure of the pressing plate body 1 needs to be improved, and the positioning column 6 needs to be arranged on the pressing plate body 1. The second positioning assembly is given in the embodiment to solve the problem of changing the structure of the pressing plate body 1 itself.

[0034] As shown in Figure 2 and 3 , the positioning assembly includes a limiting plate 7 placed on the top end of the pressing plate body 1, and four limiting blocks 8 arranged in a rectangular array on the bottom end face of the limiting plate 7 and attached to the side face of the pressing plate body 1. The end face of the limiting plate 7 is provided with an opening through the mounting hole, and two positioning columns 6 are arranged on the top end face of the limiting plate 7 and symmetrically arranged about the opening. When the screw rod 2 passes through the opening and the mounting hole, the limiting plate 7 and the pressing plate body 1 are installed by the control column 3. The control column 3 drives the limiting plate 7 and the pressing plate body 1 below to move downward and deform concave. The two positioning columns 6 on the deformed limiting plate 7 are close to each other and arranged in the positioning groove 5.

[0035] The embodiment increases the limiting plate 7, and the limiting block 8 is arranged at the bottom end of the limiting plate 7 and is attached to the side surface of the pressing plate body 1, so that the position of the limiting plate 7 on the pressing plate body 1 is relatively stable, and the limiting plate 7 is accurately placed on the pressing plate body 1, the sliding or deviation of the limiting plate 7 in the horizontal direction is prevented, the foundation for the subsequent installation of the screw rod and the stable work of the whole assembly is laid, at this time, the two positioning columns 6 are symmetrically arranged on the limiting plate 7 about the hole, when the screw rod 2 and the control column 3 install the pressing plate body 1, the control column 3 synchronously moves downward with the limiting plate 7 and the pressing plate body 1, so that the limiting plate 7 and the pressing plate body 1 are synchronously deformed downward, at this time, the top of the two positioning columns 6 on the end surface of the limiting plate 7 is close to each other, at this time, the control column 3 is arranged in the positioning groove 5 arranged on the side surface of the control column 3, the position between the control column 3 and the pressing plate body 1 is fixed, so that the self-locking between the pressing plate body 1 and the control column 3 when the installation of the pressing plate body 1 is completed is realized.

[0036] Embodiment 4: For the fixing of the position between the pressing plate body 1 and the control column 3 of the second positioning assembly in embodiment 3, when the pressing plate body 1 is deformed, the end of the positioning column 6 on the limiting plate 7 is arranged in the positioning groove 5 to realize the position fixing between the control column 3 and the pressing plate body 1, and the third positioning assembly solution is given in the embodiment.

[0037] As shown in Figure 5 and Figure 6 , the positioning assembly comprises the limiting plate 7 placed on the top end of the pressing plate body 1, the four limiting blocks 8 arranged in a rectangular array on the end face of the bottom end of the limiting plate 7 and attached to the side surface of the pressing plate body 1, the positioning ring 9 fixedly arranged on the end face of the top end of the limiting plate 7, and the positioning piece arranged on the control column 3 and fixed between the positioning ring 9, and the opening through hole is arranged on the end face of the inner ring of the limiting plate 7.

[0038] As shown in Figure 7 and Figure 8 , the positioning piece comprises two fixed blocks 16 symmetrically and movably arranged in the telescopic groove 12 arranged on the symmetric side surface of the control column 3, and the control structure arranged on the control column 3 and controlling the movement of the two fixed blocks 16 outside the telescopic groove 12 into the telescopic groove 12, and the fixed grooves 17 are arranged on the opposite side surfaces of the two fixed blocks 16; the positioning grooves 10 matched with the fixed grooves 17 are arranged on the inner ring of the positioning ring 9.

[0039] The embodiment is first controlled by the control structure to control the two fixed blocks 16 to be inserted into the telescopic slot 12 when the driving control column 3 is rotated. At this time, the control column 3 can be rotated relative to the pressing plate body 1, and when the pressing plate body 1 is deformed and installed, the control of the control structure is released at this time. The two fixed blocks 16 will move away from each other under the action of the control structure. At this time, the two fixed blocks 16 are away from each other and abut on the inner ring of the positioning ring 9. At this time, the fixed groove 17 is clamped with the positioning groove 10, so that the position between the control column 3 and the positioning ring 9 is fixed.

[0040] It can be understood that the function of controlling the two fixed blocks 16 to move from the outside of the telescopic slot 12 to the inside of the telescopic slot 12 can be realized in various ways. The embodiment gives the following solution:

[0041] As shown in Figure 8 , the control column 3 is provided with a control slot 4 at the top, and the control structure includes a lifting block 11 movably inserted into the lifting slot 13 opened at the bottom wall of the control slot 4, a telescopic rod 14 arranged on the bottom wall of the lifting slot 13 and connected with the lifting block 11, and a telescopic spring 15 sleeved on the rod of the telescopic rod 14 and connected with the lifting block 11 and the bottom wall of the lifting slot 13 at both ends. When the telescopic spring 15 is in normal elongation state, the lifting block 11 is located at the opening position of the lifting slot 13, and the lifting block 11 is connected with the two fixed blocks 16 through the connecting structure.

[0042] When the wrench (internal hexagonal wrench) is inserted into the control slot 4 at one end, the end of the wrench pushes the lifting block 11 to move into the lifting slot 13, compresses the telescopic spring 15 on the rod of the telescopic rod 14, and the lifting block 11 is connected with the two fixed blocks 16 through the connecting structure, which drives the two fixed blocks 16 to move close to each other. When the driving control column 3 is rotated, the two fixed blocks 16 are inserted into the telescopic slot 12. After the installation of the pressing plate body 1 is completed, the wrench is controlled to move away. At this time, the lifting block 11 is driven to move upward under the elastic force of the telescopic spring 15. At this time, the two fixed blocks 16 are driven to move out of the telescopic slot 12 through the connecting structure. The fixed blocks 16 and the positioning groove 10 and the fixed groove on the positioning ring 9 are clamped to realize the fixation of the position between the fixed blocks 16 and the positioning ring 9.

[0043] It can be understood that the lifting block 11 can be vertically lifted and the fixed block 16 can be moved in and out of the telescopic slot 12 in linkage. The embodiment gives the following solution:

[0044] As shown in Figure 8As shown, the connecting structure comprises two first connecting rods 18 vertically arranged on opposite faces of the two fixing blocks 16, two second connecting rods 19 vertically arranged on adjacent end portions of the two first connecting rods 18 respectively in the vertical direction, and two linkage rods 20 respectively rotationally connected to symmetrical side faces of the lifting block 11 at one end and to top portions of the two second connecting rods 19 at the other end.

[0045] When the lifting block 11 moves downward in the lifting groove 13, the two second connecting rods 19 are brought close to each other by the two linkage rods 20, i.e. the two first connecting rods 18 are brought close to each other, and the two first connecting rods 18 are connected to the fixing blocks 16, so that the fixing blocks 16 are moved in the telescopic groove 12 or outside the telescopic groove 12 synchronously when the lifting block 11 moves vertically.

[0046] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
