Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment, and in particular to a quick disassembly and assembly structure for air conditioning blades and drive shaft. Background Technology

[0002] To achieve left-right oscillation, existing vertical air conditioner indoor units typically feature left and right sway blades at the air outlet. These blades are usually elongated, approximately 1000mm long and 90mm wide. One end of the blade is fixed to a drive shaft, and the other end to a rotating shaft. The drive shaft is connected to the motor's main shaft, and the swaying motion of the blades is achieved by the motor's rotation. Currently, the blades are connected to the drive and rotating shafts via mounting holes at both ends. Since the drive and rotating shafts are pre-fixed within the cabinet, installing the blades requires first fitting one end of the blade into the rotating shaft, then bending the blade to a certain extent until the other end fits into the drive shaft. This installation method requires significant bending force, making it difficult and prone to damaging the blades. Furthermore, if the user needs to clean the blades after a period of use, they cannot directly disassemble them from the front. They must first remove the front frame, motor, and drive shaft sequentially before removing the blades, making the entire process cumbersome and inconvenient for cleaning. Utility Model Content

[0003] To overcome the above-mentioned shortcomings of the existing louver installation method, the technical problem to be solved by this utility model is to provide a quick disassembly and assembly structure for air conditioner louvers and drive shaft that can be easily disassembled and assembled.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A quick-release structure for air conditioner louvers and drive shaft includes louvers and a drive shaft with a rectangular cross-section. The inner side of the louvers has a U-shaped groove along its length. A sliding cover plate with a length not exceeding half the length of the U-shaped groove is slidably disposed on the open side of the U-shaped groove. The sliding cover plate is anti-detached by the inner flanges on both sides and the outer flanges on the open side edge of the U-shaped groove. The drive shaft is located in the front half of the U-shaped groove. The sliding cover plate and the drive shaft are respectively provided with a first through hole and a second through hole. When the sliding cover plate is located in the front half of the U-shaped groove, the sliding cover plate presses on the drive shaft and the drive shaft is fixed to the louvers by fixing screws passing through the first through hole and the second through hole.

[0005] Furthermore, the outward flange of the opening side edge of the U-shaped groove is only provided in the front half of the U-shaped groove.

[0006] Furthermore, the U-shaped groove has an outwardly protruding arc-shaped limiting block in the middle of its side surface.

[0007] Furthermore, the sliding cover is provided with anti-slip protrusions on both sides.

[0008] The beneficial effects of this utility model are as follows: By changing the traditional mounting hole structure to a combination structure of U-shaped groove and sliding cover plate, when installing the swing blade, the sliding cover plate is slid to the rear half of the U-shaped groove, and the drive shaft can be directly inserted into the front half of the U-shaped groove through the opening of the U-shaped groove. Then, the sliding cover plate is slid back to the front half of the U-shaped groove and locked with fixing screws to achieve a fixed connection between the swing blade and the drive shaft. Disassembly can be performed by reversing the operation, which is convenient and quick. The entire installation process does not require bending the swing blade, which can improve the convenience of swing blade disassembly and facilitate users to disassemble and clean the swing blade.

Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these terms are used to describe the relative positional relationships between components and are not specific references to the absolute positions of the components or the relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture.

[0013] like Figures 1 to 3As shown, this utility model provides a quick-release structure for an air conditioner vane and drive shaft, including a vane 1 and a drive shaft 2 with a rectangular cross-section. The vane 1 has a U-shaped groove 3 along its length on its inner side. A sliding cover plate 4, with a length not exceeding half the length of the U-shaped groove 3, is slidably disposed on the open side of the U-shaped groove 3. The sliding cover plate 4 is anti-detached by its inner flanges 41 on both sides and the outer flanges 31 on the open side edge of the U-shaped groove 3. The drive shaft 2 is located in the front half of the U-shaped groove 3. The sliding cover plate 4 and the drive shaft 2 are respectively provided with a first through hole 42 and a second through hole 21. When the sliding cover plate 4 is located in the front half of the U-shaped groove 3, it presses against the drive shaft 2, and the drive shaft 2 is fixed to the vane 1 by fixing screws 5 passing through the first through hole 42 and the second through hole 21. Figure 1 As shown, the U-shaped groove 3 is located at the end of the vane 1, with its outward-facing end open to allow the drive shaft 2 to pass through. The inner end is sealed by the rib structure of the vane 1, limiting the movement of the sliding cover plate 4. The height and opening width of the U-shaped groove 3 are approximately the same as the height and width of the drive shaft 2, ensuring a tight connection between the drive shaft 2 and the U-shaped groove 3. The portion of the drive shaft 2 located in the U-shaped groove 3 does not exceed half the length of the U-shaped groove 3, and is preferably set to be the same length as the sliding cover plate 4. This allows the sliding cover plate 4 to completely enclose the drive shaft 2 within the U-shaped groove 3, thereby improving the connection strength between the drive shaft 2 and the vane 1.

[0014] The disassembly and assembly process of this utility model is as follows: When installing the swing blade 1, first slide the sliding cover plate 4 to the rear half of the U-shaped groove 3, such as... Figure 3 As shown, the drive shaft 2 is then aligned with the U-shaped groove 3, and the drive shaft 2 is inserted into the U-shaped groove 3. Next, the sliding cover plate 4 is slid back to the front half of the U-shaped groove 3. Finally, a fixing screw 5 is passed through the first through hole 42 and the second through hole 21 on the sliding cover plate 4 and the drive shaft 2, and then connected to the threaded hole on the oscillating blade 1, achieving the desired effect. Figure 2 As shown, the drive shaft 2 and the oscillating blade 1 are fixedly connected. When it is necessary to disassemble the oscillating blade 1, first loosen the fixing screw 5, then slide the sliding cover plate 4 to the rear half of the U-shaped groove 3, so that the side opening of the U-shaped groove 3 where the drive shaft 2 is located is opened, achieving the desired effect. Figure 3 As shown in the diagram, the drive shaft 2 can then be moved out of the U-shaped groove 3, thus disassembling the rotor blade 1. The entire disassembly and assembly process does not require bending the rotor blade 1, which greatly reduces the difficulty of installing the rotor blade.

[0015] The anti-detachment connection between the sliding cover plate 4 and the U-shaped groove 3 is to confine the drive shaft 2 within the U-shaped groove 3 using the sliding cover plate 4, ensuring the reliability of the connection between the drive shaft 2 and the swing blade 1. Therefore, the outward flange 31 on the opening side edge of the U-shaped groove 3 only needs to be set in the front half of the U-shaped groove 3, and the rear half does not have an outward flange 31. During installation, the sliding cover plate 4 can be installed onto the U-shaped groove 3 from the rear half first, and then slid to the front half.

[0016] To facilitate the positioning of the sliding cover 4 during the installation and removal of the swing blade 1, an outwardly protruding arc-shaped limiting block 32 is provided in the middle of the side of the U-shaped groove 3. When the sliding cover 4 is completely covered on the drive shaft 2, the rear end of the sliding cover 4 contacts the arc-shaped limiting block 32. During removal, the sliding cover 4 slides backward, and under the action of the arc-shaped limiting block 32, the sliding cover 4 deforms slightly until the front end of the sliding cover 4 passes the arc-shaped limiting block 32, at which point the sliding cover 4 returns to its original shape and contacts the arc-shaped limiting block 32, at which point the sliding cover 4 is completely disengaged from the drive shaft 2. Furthermore, to facilitate the user's movement of the sliding cover 4, anti-slip protrusions 43 are provided on both sides of the sliding cover 4.

[0017] This utility model replaces the traditional mounting hole structure with a combination structure of U-shaped groove 3 and sliding cover plate 4. When installing the swing blade 1, the sliding cover plate 4 is slid to the rear half of the U-shaped groove 3, and the drive shaft 2 can be directly inserted into the front half of the U-shaped groove 3 through the opening of the U-shaped groove 3. Then, the sliding cover plate 4 is slid back to the front half of the U-shaped groove 3 and locked with fixing screws 5 to achieve a fixed connection between the swing blade 1 and the drive shaft 2. Disassembly can be performed by reversing the operation, which is convenient and quick. The entire installation process does not require bending the swing blade 1, which can improve the convenience of disassembling the swing blade 1 and facilitate users to disassemble and clean the swing blade 1. It has good practicality and application value.
