Description

Technical Field

[0001] This utility model relates to the field of air conditioning component technology, and more specifically, to a driven sweeping blade clamping plate structure that can be adapted to the mounting holes of the middle frame. Background Technology

[0002] In many devices involving air sweeping functions, such as air conditioners and fans, the stable operation and precise control of the sweeping blades are crucial. The driven sweeping blade clamp is an important component in the air sweeping mechanism of air conditioners and other equipment. It is mainly used to install and fix the driven sweeping blades, and works with the active blades, transmission linkages and other components to realize the air sweeping function.

[0003] The existing air-sweeping clip has poor compatibility with the mounting holes of the middle frame, resulting in inconvenient installation and insufficient stability. The fixing gap between the connecting clip and the reinforcing base plate forms a stress concentration point. In addition, the material is relatively soft, and the clip is prone to deformation and breakage under stress, which shortens the service life. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides a driven sweeping blade clamping plate structure that can be adapted to the mounting holes of the middle frame, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a driven sweeping blade clamping plate structure adaptable to the mounting hole of the middle frame, including a sweeping blade clamping plate and a middle frame mounting hole, wherein multiple sweeping blades are installed on the top of the sweeping blade clamping plate, and a sweeping blade reinforcing base plate is fixedly connected to the bottom of the sweeping blade clamping plate.

[0006] The bottom of the sweeping blade reinforcing base plate is fixedly connected with multiple connecting buckles, the top of the connecting buckles is fixedly connected with a first adhesive plate, a fixing notch is formed between the connecting buckles and the sweeping blade reinforcing base plate, a second adhesive plate is fixedly connected inside the fixing notch, and buckle ribs are fixedly connected between the connecting buckles and the sweeping blade reinforcing base plate.

[0007] Preferably, the top surfaces of the sweeping blade retaining plate and the sweeping blade reinforcing base plate are provided with connecting holes, and an arc-shaped toothed plate is installed on the bottom side of the sweeping blade reinforcing base plate near the connecting holes.

[0008] Preferably, there are multiple connecting buckles, which are evenly distributed on the bottom of the sweeping blade reinforcing base plate and correspond one-to-one with the positions of the mounting holes in the middle frame.

[0009] Preferably, the second adhesive plate fills the fixing notch, so that the connecting buckle and the sweeping blade reinforcing base plate form a complete closed support structure.

[0010] Preferably, the height of the snap-fit ​​rib is adapted to the size of the mounting hole in the middle frame.

[0011] Preferably, the sweeping blade retaining plate, the sweeping blade reinforcing base plate, the connecting buckle, the first adhesive plate and the second adhesive plate are all integrally injection molded from PP material.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. After filling the gap with the second adhesive plate, the connecting buckle and the reinforcing base plate form a closed support structure. By eliminating the stress concentration point at the gap, the structural softness of the PP material is effectively improved, making the buckle less prone to deformation or breakage under stress, thus improving the fatigue resistance of the overall structure. When the first adhesive plate is assembled, it squeezes the inner wall of the middle frame hole and generates axial locking force through elastic deformation, eliminating the assembly gap between the clamp plate and the middle frame, preventing the clamp plate from loosening due to vibration during the air sweeping process, and improving the tightness and stability of the connection. The elastic margin of the first and second adhesive plates can compensate for deformation, avoiding excessive tightness or jamming due to thermal expansion and contraction, so that the clamp plate can maintain normal operation in different temperature environments.

[0014] 2. The torque generated by the rotation of the sweeping blades is transmitted to the reinforced base plate through the ribs, and the load is evenly distributed through the closed buckle structure to avoid structural fracture caused by single-point stress. The height of the buckle ribs is adapted to the assembly holes of the middle frame to avoid interference with the edge of the middle frame holes. At the same time, it can maintain the insertion depth of the connecting buckle to ensure the connection strength between the buckle plate and the middle frame, and realize the synchronous closing of the assembly structure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5 The driven sweeping blade clamping plate structure that can be adapted to the middle frame mounting hole shown includes a sweeping blade clamping plate 1 and a middle frame mounting hole. Multiple sweeping blades 2 are installed on the top of the sweeping blade clamping plate 1, and a sweeping blade reinforcing base plate 3 is fixedly connected to the bottom of the sweeping blade clamping plate 1.

[0023] Multiple connecting clips 4 are fixedly connected to the bottom of the sweeping blade reinforcing base plate 3. A first adhesive plate 5 is fixedly connected to the top of the connecting clips 4. A fixing notch 6 is formed between the connecting clips 4 and the sweeping blade reinforcing base plate 3. A second adhesive plate 7 is fixedly connected inside the fixing notch 6. Clip ribs 9 are fixedly connected between the connecting clips 4 and the sweeping blade reinforcing base plate 3.

[0024] As attached Figure 1 , 2 As shown in Figures 3 and 5, both the top surfaces of the sweeping blade clamping plate 1 and the sweeping blade reinforcing base plate 3 are provided with connecting holes 8. An arc-shaped toothed plate 10 is installed on the bottom side of the sweeping blade reinforcing base plate 3 near the connecting hole 8, so that the arc-shaped toothed plate 10 can provide friction between the plate and the middle frame connector.

[0025] As attached Figure 1-4 As shown, there are multiple connecting clips 4, which are evenly distributed on the bottom of the sweeping blade reinforcing base plate 3 and correspond one-to-one with the position of the middle frame mounting holes to ensure the assembly effect.

[0026] As attached Figure 2 , 4 As shown, the second adhesive plate 7 fills the fixed notch 6 to avoid overly tight assembly or jamming caused by thermal expansion and contraction, so that the connecting buckle 4 and the sweeping blade reinforcing base plate 3 form a complete closed support structure, improving the support effect and overall structural strength.

[0027] As attached Figure 1-4 As shown, the height of the snap-fit ​​rib 9 is adapted to the size of the mounting holes in the middle frame.

[0028] As attached Figure 1-5 As shown, the sweeping blade retaining plate 1, the sweeping blade reinforcing base plate 3, the connecting buckle 4, the first adhesive plate 5, and the second adhesive plate 7 are all made of PP material through one-piece injection molding, which improves the stability of the overall structure.

[0029] The working principle of this utility model is as follows: the sweeping blade clamping plate 1 is positioned by the sweeping blade reinforcing base plate 3 at the bottom and the middle frame assembly hole. The connecting buckles 4 are evenly distributed at the bottom of the reinforcing base plate 3, and their positions correspond one-to-one with the middle frame assembly holes to form the initial assembly positioning points. After the second adhesive plate 7 in the fixing notch 6 is filled, the connecting buckles 4 and the reinforcing base plate 3 form a closed support structure. By eliminating the stress concentration point of the notch, the buckle's anti-deformation ability is enhanced. It is adapted to the soft characteristics of PP material. When the size of the middle frame assembly hole is reduced or the position is changed, the height of the buckle rib 9 can be adapted to avoid interference with the edge of the middle frame hole. At the same time, the insertion depth of the connecting buckle 4 is maintained to achieve synchronous closing. The rib 9 transmits the torque generated when the sweeping blade 2 rotates to the reinforcing base plate 3. The load is distributed through the closed buckle structure to prevent breakage caused by single-point force.

[0030] The sweeping blade 2 is fixed to the top of the clamping plate 1 through the connecting hole 8. The connecting buckle 4 at the bottom of the reinforcing base plate 3 is aligned with the middle frame assembly hole. The first adhesive plate 5 presses the inner wall of the middle frame hole, and the elastic deformation generates axial locking force to eliminate assembly gaps. When the sweeping blade 2 rotates, the torque is transmitted to the reinforcing base plate 3 through the clamping plate 1, and then distributed to the middle frame by the buckle rib 9 and the closed buckle structure. The second adhesive plate 7 prevents cracks from forming at the fixing notch 6 due to long-term stress, ensuring the structural life. When the PP material expands due to temperature, the elasticity of the first adhesive plate 5 and the second adhesive plate 7 can compensate for the deformation and avoid jamming caused by excessive assembly.

[0031] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
