[0021] The sweeping blade provided by this utility model optimizes the installation process and improves its assembly efficiency. Firstly, it provides an installation structure for the sweeping blade, including a limiting post and a slot; the limiting post and slot are disposed on the sweeping blade. Secondly, it provides an air outlet frame, including a notched rotating shaft; the notch is located at the center of the lower end of the assembly portion of the sweeping blade rotating shaft in the air outlet frame. The notched rotating shaft of the air outlet frame forms a rotatable connection by inserting into the sweeping blade slot, without needing to insert from above the slot. This optimizes the installation process of the sweeping blade and improves the overall assembly efficiency of the air conditioner. Especially when both ends of the sweeping blade need to be fixed, the side-mounting method effectively avoids the deformation and damage to the mounting body (such as the side wall at the air outlet or the sweeping blade) caused by front-mounting, thus reducing maintenance costs.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] like Figures 1-10 As shown, this utility model provides an installation structure 10, including a rotating shaft 3, a slot 5, and a limiting post 6; wherein:

[0040] The rotating shaft 3 is located at one end of the sweeping blade 4. The rotating shaft 3 has an assembly part 8. The diameter of the assembly part 8 is smaller than that of the rotating shaft 3. The assembly part 8 has a notch 9. The notch 9 is used to align the rotating shaft 3 with the limiting post 6 when it is inserted into the slot 5, so as to facilitate insertion.

[0041] The slot 5 has a notch 51 on one side for the assembly part 8 to pass through; the upper end specification a of the slot 5 is 3.8-4.2mm; by partially cutting the side wall of a cylindrical slot 5, a notch 51 structure is formed on one side of the slot 5. This notch 51 structure allows the assembly part 8 of the rotating shaft 3 to be inserted into the slot 5 from the side of the slot 5. During assembly, it is not only convenient to align, but also the assembly of the sweeping blade 4 can be completed without bending the sweeping blade 4.

[0042] The limiting post 6 is set at the notch 51, and the distance between the end of the limiting post 6 near the center of the slot 5 and the center of the slot 5 should be less than or equal to the radius of the assembly part 8.

[0043] The limiting post 6 and the notch 9 are compatible in specifications. When the assembly part 8 is inserted into the slot 5 through the notch 9 and the limiting post 6, the limiting post 6 is locked on the outside of the assembly part 8.

[0044] During installation, align the notch 9 on the assembly part 8 of the rotating shaft 3 with the limiting post 6 at the notch 51, and then press it down firmly so that the assembly part 8 is inserted into the slot 5. After being inserted, the assembly part 8 can abut against the limiting post 6, thereby realizing the individual limiting and anti-slip structure of each sweeping blade.

[0045] The installation structure provided by this utility model, by opening a slot 5 and adding a limiting post 6 at the upper end of the sweeping blade 4, and adding a matching notch with a rounded chamfer to the rotating shaft 3 of the air outlet frame 2, enables the sweeping blade 4 to be inserted and installed from the side without bending, reducing installation inconvenience and improving production efficiency. It also solves the problems of unstable alignment of the mounting hole shaft when installing the sweeping blade 4 assembly, which is laborious and inconvenient, and easily causes damage to the air outlet frame 2 and the sweeping blade 4.

[0046] In this embodiment, the notch 9 is a rectangular structure that is provided through the middle of the assembly part 8. That is, the notch 9 is opened in the middle of the assembly part 8 and is provided through the middle. When the assembly part 8 is inserted into the slot 5, the limiting post 6 can pass through from one side of the notch 9 to the other side. After passing through to the other side, when the sweeping blade 4 rotates, it plays a role in abutting the assembly part 8 and plays a role in preventing slippage.

[0047] To facilitate alignment and quick insertion, the limiting post 6 is a rectangular plate-like structure, and its thickness is matched to the width of the notch 9. For example, as... Figure 6 As shown, the width of the limiting post 6 is b, and the width of the notch 9 is c. b should not be greater than c; b can be equal to c or slightly less than c. The width c of the notch 9 of the air outlet frame 2 and the notch type rotating shaft 3 is 1.1 to 1.2 mm, and the corners are rounded for easy installation; the maximum angle d of the sweeping blades 4 does not exceed 120°.

[0048] To prevent insufficient longitudinal limiting function of the slot 5, a limiting post 6 is added in the middle. The width b of the limiting post 6 is smaller than the width c of the notch 9 of the air outlet frame notch-type rotating shaft 3. The width b of the limiting post 6 is 0.8-1.0mm.

[0049] like Figure 4 As shown, the assembly part 8 has a stepped structure, including an arc-shaped gradient section and a straight section; the inner wall of the slot 5 has a stepped structure, including a first mating groove and a second mating groove; the first mating groove is adapted to the specifications of the gradient section; the second mating groove is adapted to the specifications of the straight section.

[0050] To prevent damage caused by interference or high stress during snap-fitting or insertion, in this embodiment, both the inner and outer side walls of the notch have arc-shaped transition structures; it should be noted here that, as Figure 6 and Figure 8 As shown, the inner and outer side walls of the notch refer to the side wall closer to the center of the slot 5 and the side wall farther from the center of the slot 5, respectively. By setting the inner and outer side walls with arc transitions, the assembly part 8 can avoid damage when it enters through the notch 51, and can be easily inserted from the side.

[0051] In this embodiment, the corners of the limiting post 6 are all arc-shaped transition structures; the corners of the inner wall of the slot 5 are all arc-shaped transition structures; the corners of the notch 9 are all arc-shaped transition structures; and the connection between the assembly part 8 and the rotating shaft 3 is an arc-shaped transition structure.

[0052] By setting all contact points, corners, and edges with rounded transition structures, not only is a good guiding effect achieved, but stress concentration at contact and engagement points is also reduced, preventing damage.

[0053] As an optional embodiment of this utility model, the end of the assembly part 8 is a hemispherical end face; the bottom of the slot 5 is a hemispherical bottom face that matches the specifications of the end of the assembly part 8.

[0054] Furthermore, in this embodiment, the height of the limiting post 6 is not greater than the height of the notch 9.

[0055] It should be noted that the rotating shaft 3 is an integral structure; of course, as another optional embodiment of this utility model, the rotating shaft 3 can also be a split structure. However, when the rotating shaft 3 is a split structure, the number of parts increases and an additional assembly process is added, which increases the cost and reduces the production efficiency, and is not the optimal embodiment.

[0056] like Figure 2 As shown, a stepped section 7 with rounded corners is added to the limiting post so that the rotating shaft 3 with the stepped structure can be smoothly inserted from the side. The lower end of the limiting post 6 is rounded at the connection with the sweeping blade 4 to prevent damage due to excessive stress during installation.

[0057] like Figures 1-10 As shown, the present invention provides a sweeping blade 4, which includes a blade body. One end of the blade body is rotatably connected to the installation position via a cylindrical rotating shaft 20; the other end of the blade body is rotatably connected to the installation position via an installation structure 10.

[0058] Furthermore, the installation location is the air outlet frame 2. One end of the blade body is provided with a rotating shaft 20, and a limiting groove 30 is provided at the corresponding position on the air outlet frame 2. The rotating shaft 20 is inserted into the limiting groove 30 to achieve a rotatable connection at one end of the blade body. The other end of the blade body is provided with a slot 5 with a notch 51, and a limiting post 6 is provided at the notch 51 position. The air outlet frame 2 is provided with a rotating shaft 3 with a notch 9. The rotating shaft 3 is inserted into the limiting post 6 through the notch 9, and then inserted into the slot 5.

[0059] The sweeping blade 4 provided by this utility model optimizes the installation process of the sweeping blade 4 and improves its assembly efficiency. On one hand, it provides an installation structure for the sweeping blade 4, which includes a limiting post 6 and a slot 5; the limiting post 6 and the slot 5 are disposed on the sweeping blade 4. Specifically, the upper end of the sweeping blade 4 has a slot 5 and a limiting post 6. It also provides an air outlet frame 2, including a notch 9 type rotating shaft 3; the notch 9 is located at the center of the lower end assembly part 8 of the rotating shaft 3 of the sweeping blade 4 in the air outlet frame 2, and the edge of the notch 9 has a rounded chamfer; the notch 9 type rotating shaft 3 of the air outlet frame 2 is connected by an insertion... The air sweeping blade 4 is connected to the slot 5 by a rotating connection, eliminating the need to insert it from the top of the slot 5. This allows the air sweeping blade 4 to be inserted and installed from the side without bending, optimizing the installation process, reducing installation inconvenience, and thus improving production efficiency and the overall assembly efficiency of the air conditioner. Especially when both ends of the air sweeping blade 4 need to be fixed, the side installation method can effectively avoid the deformation of the installation body (such as the side wall at the air outlet of the air conditioner or the air sweeping blade 4) caused by front installation, which may result in damage and reduce maintenance costs.

[0060] like Figures 1-10 As shown, the present invention provides an air outlet frame 2, which includes a frame body installed at the air outlet and a plurality of sweeping blades 4 installed in the frame body; a cylindrical limiting groove 30 is provided on one side of the frame body, and a slot 5 is provided on the other side of the frame body; one end of the blade body is connected to the limiting groove 30 through a rotating shaft 20; the other end of the blade body is connected to the slot 5 through a rotating shaft 3.

[0061] like Figures 1-10 As shown, the present invention provides an air conditioner including an air outlet, an air outlet panel 1, and an air outlet frame 2; wherein:

[0062] The air outlet is located on the air outlet panel 1;

[0063] The air outlet frame 2 is installed on the air outlet.

[0064] In this embodiment, a slot 5 is formed at the upper end of the sweeping blade 4 to mate with the rotating shaft 3 of the air outlet frame 2. The shape of the slot 5 is based on the original hole structure, with material removed and chamfered to facilitate lateral entry of the notch-type rotating shaft 3 of the air outlet frame 2. The slot 5 should be easy to install and not easy to slip out. The slot size should not be too large or too small. The width 'a' of the slot 5 at the upper end of the sweeping blade 4 is 3.8-4.2 mm. The slot at the upper end of the sweeping blade 4 is rounded to prevent interference when assembling with the notch-type rotating shaft 3 of the air outlet frame 2.

[0065] To prevent insufficient longitudinal limiting function of the slot 5, a limiting post 6 is added in the middle. Its main purpose is to prevent the rotating shaft 3 of the air outlet frame 2 from slipping off due to vibration or when the sweeping blade 4 is working normally after assembly with the slot 5 of the sweeping blade 4. Although there is a connecting rod between the sweeping blades 4 to prevent slippage, the limiting post 6 provides an extra layer of protection. The width b of the limiting post 6 is smaller than the notch width c of the rotating shaft 3 of the air outlet frame 2. The width b of the limiting post 6 is 0.8-1.0mm.

[0066] A rounded step 7 is added to the top of the limiting post 6 so that the notch-type rotating shaft 3 of the air outlet frame with the stepped structure can be smoothly inserted from the side. The lower end of the rotating shaft 3 is rounded at the connection with the sweeping blade 4 to prevent damage from excessive stress during installation.

[0067] The notch width c of the air outlet frame notch-type rotating shaft 3 is 1.1-1.2mm. This dimension is larger than the width b of the limiting post 6. This can cause the sweeping blade groove 5 to squeeze the outside of the air outlet frame notch-type rotating shaft 3 during installation and pressing, resulting in a reversible deformation. The notch is rounded at the contact point with the limiting post 6 to facilitate installation.

[0068] Through physical verification, the maximum angle d of the sweeping blade 4 does not exceed 120°, which can ensure that the sweeping blade 4 will not rotate back to the installation position when it moves, so that the air outlet frame rotation shaft 3 will slip off from the sweeping blade slot 5.

[0069] The installation process is as follows: First, install the rotating shaft 20 of the sweeping blade 4 with the limiting groove 30 of the air outlet frame 2. Then, use the limiting post 6 of the sweeping blade 4 to press it against the notch 9 of the rotating shaft 3 of the air outlet frame 2 by hand. After pressing it in, rotate it to complete the installation.

[0070] First, it should be noted that "inward" refers to the direction towards the center of the storage space, while "outward" refers to the direction away from the center of the storage space.
