Technical Field
[0001] This application relates to the field of refrigerator technology, and more particularly to a door and a refrigerator. Background Technology
[0002] As living standards improve, users' demands for refrigerator appearance are constantly increasing. Currently, refrigerators with a metallic finish are becoming increasingly popular. Based on this, high-end refrigerators with glass panels typically use aluminum alloy handles for their doors. Aluminum alloy handles give the refrigerator a more upscale look and provide users with a better tactile experience. Meanwhile, high-end refrigerators with metal panels are increasingly adopting stainless steel panels, which also offer a more sophisticated metallic look.
[0003] Chinese patent application number CN201810758039.8 discloses a refrigerator door frame assembly, belonging to the refrigerator field. This refrigerator door frame assembly is a symmetrical component, including a handle trim strip extending along the width of the refrigerator; a trim strip connector connected to one end of the handle trim strip, forming a first groove between the connector and the strip, the groove being recessed from the end of the trim strip towards its center; a sheet metal trim strip extending along the height of the refrigerator and connected to the side of the connector away from the handle trim strip, one end of which has a protruding locking strip near the connector, extending into the first groove and forming a first insertion connection; and an injection-molded trim strip positioned parallel to the bottom of the handle trim strip, one end of which is connected to the end of the sheet metal trim strip away from the connector. This refrigerator door frame assembly effectively prevents the sheet metal trim strip from rusting.
[0004] However, given the trend towards metallic finishes in refrigerators, stainless steel panels paired with aluminum alloy door handles can significantly enhance the premium look of a refrigerator. However, due to structural and material limitations of both aluminum alloy handles and metal panels (metal panels are typically 0.5mm thick), it's difficult to directly machine a 0.7-0.8mm seam into the aluminum alloy handle, making direct assembly impossible with existing methods. Therefore, refrigerators with metal panels often use plastic door handles, severely impacting the user experience. Utility Model Content
[0005] To address the problem of difficulty in securing existing aluminum alloy handles to metal panels, this application provides a door and a refrigerator.
[0006] Firstly, the door body provided in this application adopts the following technical solution: A door body includes a metal panel and a handle assembly, wherein the handle assembly is fixedly connected to the upper end of the metal panel; The handle assembly is provided with a panel slot, which extends from the upper end of the front of the handle assembly to both sides; the handle assembly includes an aluminum alloy handle and a handle bushing, which is fixedly connected to the lower part of the aluminum alloy handle; The top and sides of the metal panel have contoured edges that match the shape of the aluminum alloy handle end, with the first flange extending inward. The metal panel is connected to the panel slot on the handle assembly via the first flange.
[0007] By adopting the above technical solution, during door panel assembly, the aluminum alloy handle and handle bushing can be assembled first, forming a panel slot on the side of the handle assembly near the metal panel, simultaneously securing the plastic handle bushing to the aluminum alloy handle. Then, the first flange on the metal panel is inserted into the panel slot on the handle assembly, thus achieving a convenient connection between the metal panel and the aluminum alloy handle. Furthermore, because the metal panel has a U-shaped structure with open top, bottom, and rear, the connection point between the first flange and the handle assembly provides horizontal and vertical restraint on the aluminum alloy handle, preventing misalignment, separation, or detachment between the assembled aluminum alloy handle and the metal panel, ensuring a long-lasting and stable connection. Moreover, since all visible surfaces of the door are made of metal, this significantly enhances the high-end feel of the refrigerator door.
[0008] Furthermore, the outer edge of the top surface of the front top of the handle liner is provided with a first step extending from its front to both sides; When the aluminum alloy handle is snapped into place with the handle bushing, the lower wall of the aluminum alloy handle and the first step of the handle bushing together form the panel slot.
[0009] By adopting the above technical solution, the panel slot is formed by the first step and the lower wall of the aluminum alloy handle. This simplifies the design complexity of the handle bushing and ensures a stable connection between the handle bushing and the aluminum alloy handle while minimizing the amount of material used in the handle bushing.
[0010] Furthermore, the first step has several ribs on the side of the lower wall of the front top of the aluminum alloy handle, and a gap is reserved between the ribs and the lower wall of the front top of the aluminum alloy handle for the first flange insertion.
[0011] By adopting the above technical solution, a gap is formed between the multiple spaced ribs and the lower wall of the aluminum alloy handle for the insertion of the first flange, which can improve the convenience of inserting the metal panel into the panel slot after the aluminum alloy handle and handle bushing are assembled; in addition, the arrangement of multiple ribs makes it easier for the aluminum alloy handle and handle bushing to clamp the metal panel more firmly and evenly, thereby improving the connection stability between the metal panel and the aluminum alloy handle.
[0012] Furthermore, the first step includes a horizontal section and a vertical section, the rib is provided on the horizontal section, and the vertical section is used to attach to the metal panel.
[0013] By adopting the above technical solution and with the help of the vertical section, on the one hand, the contact area between the first step and the metal panel can be increased, so that after the first flange of the metal panel is fixed into the handle assembly, the vertical section can also effectively support the main body of the metal panel; on the other hand, since the first step surrounds the front and sides of the handle bushing, the vertical section can significantly improve the structural rigidity of the plastic handle bushing, so that it can provide good fixation and support for the aluminum alloy handle.
[0014] Furthermore, the first step on the front of the handle liner is provided with a plurality of first through holes, and the front of the buckle groove on the aluminum alloy handle is provided with a plurality of first buckles, which are engaged with the first through holes.
[0015] By adopting the above technical solution, when the first flange on the metal panel is inserted into the panel slot between the first step and the aluminum alloy handle, the first buckle on the aluminum alloy handle is engaged with the first through hole in the first step on the handle bushing. This can achieve a stable connection between the handle bushing and the front of the aluminum alloy handle and the front of the handle bushing, and evenly control the slot width gap of the control panel slot, thereby improving the stability of the connection between the metal panel and the aluminum alloy handle and handle bushing, and avoiding local warping.
[0016] Furthermore, the bottom of the buckle groove on the handle liner is provided with a plurality of second through holes, the second through holes extending upward to the rear wall surface of the buckle groove on the handle liner, and forming a second step on the rear wall surface of the handle liner; The aluminum alloy handle is provided with multiple second buckles on the inner side of its rear wall, and the second buckles are engaged with the second step at the rear of the second through hole.
[0017] By adopting the above technical solution, after the multiple second buckles set on the inner side of the rear wall of the aluminum alloy handle are connected to the second buckles on the rear wall of the handle liner, a stable connection can be made between the aluminum alloy handle and the back part of the handle liner. Together with the snap-fit connection of the first buckle and the first through hole, a stable connection of the aluminum alloy handle and the handle liner as a whole is achieved, resulting in a higher fit between the two. Moreover, the snap-fit connection between the aluminum alloy handle and the handle liner does not require the use of screws for fixation, avoiding the possibility of fastener rusting, and also ensuring the clean appearance of the aluminum alloy handle.
[0018] Furthermore, the rear of the top of the aluminum alloy handle is provided with a downward-facing second flange, which is fastened to the rear wall surface of the top of the handle liner.
[0019] By adopting the above technical solution, the second flange can limit the lower edge of the rear wall of the handle liner, so that the aluminum alloy handle and the handle liner are not easy to fall off upward after being snapped together, thus improving the firmness of the connection between the two.
[0020] Furthermore, a third step is provided on the rear wall surface of the top rear part of the handle liner, and a third buckle is provided on the lower part of the inner side of the second flange of the aluminum alloy handle, and the third buckle is engaged with the third step.
[0021] By adopting the above technical solution, after the rear wall of the aluminum alloy handle is engaged with the rear wall of the handle liner, the third buckle on the second flange of the aluminum alloy handle is further engaged with the third step on the handle liner, which can further improve the connection stability between the handle liner and the aluminum alloy handle and significantly reduce the probability of shaking after the aluminum alloy handle and the handle liner are engaged.
[0022] Furthermore, multiple reinforcing ribs are provided between the rear wall surface and the front wall surface of the top rear part of the handle liner.
[0023] By adopting the above technical solution, the setting of multiple reinforcing ribs can improve the shaping strength of the second flange and the handle liner body, ensure the snap-fit stability of the second step and the second buckle and the snap-fit stability of the third step and the third buckle, and thus ensure the long-term effectiveness of the snap-fit between the rear wall of the aluminum alloy handle and the rear wall of the handle liner.
[0024] Secondly, this application provides a refrigerator, which includes a cabinet and a door as described above, covering the front of the cabinet.
[0025] By adopting the above technical solution, the aluminum alloy handle and handle bushing connected by multiple buckles on the refrigerator door are fixed to the metal panel, so that the visible surface of the refrigerator door is made of metal, which greatly enhances the high-end texture of the refrigerator's appearance, and also solves the problem that the existing aluminum alloy handle and metal panel are not easy to fix.
[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. After assembling the aluminum alloy handle and handle bushing, a panel slot is formed on the side of the handle assembly near the metal panel, simultaneously securing the plastic handle bushing to the aluminum alloy handle. Then, the first flange on the metal panel is inserted into the panel slot on the handle assembly, thus achieving a convenient connection between the metal panel and the aluminum alloy handle. Furthermore, because the metal panel has a U-shaped structure with open top, bottom, and rear ends, the connection point between the first flange and the handle assembly provides horizontal and vertical restraint on the aluminum alloy handle, preventing misalignment, separation, or detachment between the assembled aluminum alloy handle and the metal panel, ensuring a long-lasting and stable connection. Moreover, this design, with all visible surfaces of the door made of metal, greatly enhances the high-end feel of the refrigerator door. 2. The gap between the multiple spaced ribs and the lower wall of the aluminum alloy handle forms a gap for the insertion of the first flange, which can improve the convenience of inserting the metal panel into the panel slot after the aluminum alloy handle and handle bushing are assembled; in addition, the setting of multiple ribs also makes it easier for the aluminum alloy handle and handle bushing to clamp the metal panel more firmly and evenly, improving the connection stability between the metal panel and the aluminum alloy handle. 3. By using the vertical section of the first flange, on the one hand, the contact area between the first step and the metal panel can be increased, so that after the first flange of the metal panel is fixed into the handle assembly, the vertical section can also effectively support the main body of the metal panel; on the other hand, since the first step surrounds the front and sides of the handle bushing, the vertical section can significantly improve the structural rigidity of the plastic handle bushing, enabling it to provide good fixation and support for the aluminum alloy handle. 4. When the first flange on the metal panel is inserted into the panel slot between the first step and the aluminum alloy handle, the first buckle on the aluminum alloy handle is engaged with the first through hole in the first step on the handle bushing. This enables a stable connection between the handle bushing and the front of the aluminum alloy handle, and evenly controls the slot width gap of the control panel slot, improving the stability of the connection between the metal panel and the aluminum alloy handle and handle bushing, and preventing local warping. 5. After the multiple second buckles set on the inner side of the rear wall of the aluminum alloy handle are engaged with the second buckles on the rear wall of the handle bushing, the back of the aluminum alloy handle and the handle bushing can be stably connected. Together with the engagement of the first buckle and the first through hole, the aluminum alloy handle and the handle bushing are stably connected as a whole, resulting in a higher fit between the two. Moreover, the snap-fit connection between the aluminum alloy handle and the handle bushing does not require the use of screws for fixing, avoiding the possibility of fasteners rusting, and also ensuring the clean appearance of the aluminum alloy handle. 6. The second flange can limit the lower edge of the rear wall of the handle bushing, so that the aluminum alloy handle and the handle bushing are not easy to fall off upward after they are snapped together, thus improving the firmness of the connection between the two. After the rear wall of the aluminum alloy handle and the rear wall of the handle bushing are snapped together, the third buckle on the second flange of the aluminum alloy handle is further snapped together with the third step on the handle bushing, which can further improve the connection stability between the handle bushing and the aluminum alloy handle and significantly reduce the probability of shaking after the aluminum alloy handle and the handle bushing are snapped together. 7. The addition of multiple reinforcing ribs can improve the shaping strength of the second flange and the handle liner body, ensure the snap-fit stability of the second step and the second buckle as well as the snap-fit stability of the third step and the third buckle, and thus ensure the long-term effectiveness of the snap-fit between the rear wall of the aluminum alloy handle and the rear wall of the handle liner. 8. The aluminum alloy handle and handle bushing on the refrigerator door are fixed to the metal panel by multiple snap-fit connections, so that the visible surface of the refrigerator door is made of metal, which greatly enhances the high-end texture of the refrigerator's appearance and solves the problem of the existing aluminum alloy handle and metal panel being difficult to fix.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0031] Example 1: Reference Figures 1-11 This application discloses a door body, which includes a metal panel 21 and a handle assembly 22, wherein the handle assembly 22 is fixedly connected to the upper end of the metal panel 21. The metal panel 21 has a U-shaped structure with open top and bottom ends and rear, and its side top has a Z-shaped contoured edge. The front top of the metal panel 21 and the Z-shaped contoured edge are provided with a first flange 211 extending inward. The handle assembly 22 is provided with a panel slot 221, which extends along the upper end of the front side of the handle assembly 22 to both sides. The metal panel 21 is connected to the panel slot 221 on the handle assembly 22 via the first flange 211.
[0032] Among them, reference Figure 2 , Figure 3 and Figure 4The handle assembly 22 includes an aluminum alloy handle 222 and a handle liner 223, with the handle liner 223 fixedly connected to the lower part of the aluminum alloy handle 222. The aluminum alloy handle 222 is U-shaped with a higher front and lower back and an open top. It has a front top, a groove, and a rear top from front to back, with the rear top being higher than the front top. The handle liner 223 is made of plastic and is designed to conform to the shape of the aluminum alloy handle 222. The Z-shaped contoured edge on the top side of the metal panel 21 is adapted to the shape of the ends of the aluminum alloy handle 222 and the handle liner 223.
[0033] Therefore, when assembling the door panel, the aluminum alloy handle 222 and handle bushing 223 can be assembled first, so that a panel slot 221 is formed on the side of the handle assembly 22 near the metal panel 21. The panel slot 221 is distributed on the lower front top side, the lower end side, and the rear side of the aluminum alloy handle 222. At the same time, the plastic handle bushing 223 and the metal aluminum alloy handle 222 can be fixedly connected. Then, the metal panel 21 is appropriately pried open and inserted onto the handle assembly 22, with the first flange 211 inserted into the panel slot 221 on the handle assembly 22. This allows for a convenient connection between the metal panel 21 and the aluminum alloy handle 222. Moreover, since the metal panel 21 has a U-shaped structure with open top, bottom, and rear ends, the connection points between the first flange 211 and the handle assembly 22 are distributed on the front and Z-shaped contoured edges of the metal panel 21. This provides horizontal and vertical restraint to the aluminum alloy handle 222, preventing misalignment, separation, or detachment between the assembled aluminum alloy handle 222 and the metal panel 21, ensuring a long-lasting and stable connection. Furthermore, the fact that all visible surfaces of the door 2 are made of metal greatly enhances the high-end appearance of the door 2 on the refrigerator 100.
[0034] Specifically, refer to Figure 4 , Figure 5 and Figure 6 The handle liner 223 has a first step 2231 extending from its front to both sides on the outer edge of its top surface; When the aluminum alloy handle 222 is snapped into place with the handle liner 223, the lower wall of the front top of the aluminum alloy handle 222 and the upper wall of the first step 2231 of the handle liner 223 form the panel slot 221.
[0035] Furthermore, referring to Figure 2 and Figure 6The first step 2231 has a plurality of spaced ribs 2232 on the side of the lower wall near the front top of the aluminum alloy handle 222. A gap is reserved between the top of the ribs 2232 and the lower wall of the front top of the aluminum alloy handle 222 for the insertion of the first flange 211. The top of the ribs 2232 is chamfered to facilitate the insertion of the first flange 211 into the insertion gap. After the aluminum alloy handle 222 and the handle bushing 223 are snapped together, the insertion gap is 0.7 to 0.8 mm to facilitate the insertion of the 0.5 mm metal panel 21 and reserve an assembly gap.
[0036] The panel slot 221 is formed by the first step 2231 and the lower wall of the aluminum alloy handle 222. This simplifies the design complexity of the handle bushing 223, ensuring a stable connection between the handle bushing 223 and the aluminum alloy handle 222 while minimizing the material used in the handle bushing 223. Furthermore, the multiple spaced ribs 2232 create a gap between themselves and the lower wall of the aluminum alloy handle 222 for the insertion of the first flange 211. This improves the ease of inserting the metal panel 21 into the panel slot 221 after the aluminum alloy handle 222 and handle bushing 223 are assembled. Additionally, the multiple plastic ribs 2232 fully utilize the properties of plastic, facilitating a more secure and even clamping of the metal panel 21 by the aluminum alloy handle 222 and handle bushing 223, thus enhancing the connection stability between the metal panel 21 and the aluminum alloy handle 222.
[0037] Furthermore, the first step 2231 includes a horizontal section and a vertical section. The rib 2232 is disposed on the horizontal section, and the vertical section is used to abut the metal panel 21. The vertical section increases the contact area between the first step 2231 and the metal panel 21, allowing the vertical section to effectively support the main body of the metal panel 21 after the first flange 211 of the metal panel 21 is fixed to the handle assembly 22. Additionally, since the first step 2231 surrounds the front and sides of the handle bushing 223, the vertical section significantly improves the structural rigidity of the plastic handle bushing 223, enabling it to provide good fixation and support for the aluminum alloy handle 222.
[0038] In order to achieve a secure assembly between the handle bushing 223 and the aluminum alloy handle 222, refer to Figure 2 , Figure 4 , Figure 8 and Figure 9 The first step 2231 on the front of the handle liner 223 is provided with a plurality of first through holes 2233, and the front of the buckle groove on the aluminum alloy handle 222 is provided with a plurality of first buckles 2221, and the first buckles 2221 are snapped into the first through holes 2233.
[0039] Furthermore, the bottom of the buckle groove on the handle liner 223 is provided with a plurality of second through holes 2234, the second through holes 2234 extending upward to the rear wall of the buckle groove on the handle liner 223, and forming a second step 2235 on the rear wall of the handle liner 223; The inner rear wall surface of the aluminum alloy handle 222 is provided with multiple second buckles 2222, which are engaged with the second step 2235 at the rear of the second through hole 2234. Figure 11 As shown.
[0040] Therefore, when the first flange 211 on the metal panel 21 is inserted into the panel slot 221 between the first step 2231 and the aluminum alloy handle 222, the first buckle 2221 on the aluminum alloy handle 222 is engaged with the first through hole 2233 in the first step 2231 on the handle bushing 223. This enables a stable connection between the handle bushing 223 and the front of the aluminum alloy handle 222, and evenly controls the gap of the control slot 221, improving the stability of the connection between the metal panel 21 and the aluminum alloy handle 222 and the handle bushing 223, and preventing local warping.
[0041] Furthermore, after the multiple second buckles 2222 set on the inner side of the rear wall of the aluminum alloy handle 222 are engaged with the second buckles 2222 on the rear wall of the handle bushing 223, a stable connection can be made between the back of the aluminum alloy handle 222 and the handle bushing 223. Together with the engagement connection of the first buckle 2221 and the first through hole 2233, a stable connection of the aluminum alloy handle 222 and the handle bushing 223 as a whole is achieved, resulting in a higher degree of fit between the two. Moreover, the engagement connection between the aluminum alloy handle 222 and the handle bushing 223 does not require the use of screws for fixing, avoiding the possibility of fasteners rusting, and also ensuring the clean appearance of the aluminum alloy handle 222.
[0042] This application also discloses a refrigerator, as shown in the embodiments. Figure 1 It includes a housing 1 and a door 2 that covers the front of the housing 1 and is as described above.
[0043] Therefore, the aluminum alloy handle 222 and handle bushing 223 connected to the metal panel 21 on the door 2 of the refrigerator 100 by multiple buckles are fixed, so that the visible surface of the door 2 of the refrigerator 100 is made of metal, which greatly enhances the high-end texture of the refrigerator 100's appearance, and also solves the problem that the existing aluminum alloy handle 222 and metal panel 21 are not easy to fix.
[0044] Example 2: Reference Figure 10 and Figure 11 This application discloses a door body, which differs from Embodiment 1 in that: Furthermore, a downward-facing second flange 2223 is provided at the rear of the top of the aluminum alloy handle 222, and the second flange 2223 is fastened to the rear wall surface of the top of the handle liner 223.
[0045] Specifically, a third step 2236 is provided on the rear wall surface of the rear top of the handle liner 223, and a third buckle 2224 is provided on the lower part of the inner side of the second flange 2223 of the aluminum alloy handle 222, and the third buckle 2224 is engaged with the third step 2236.
[0046] Therefore, the second flange 2223 can limit the lower edge of the rear wall surface of the top rear part of the handle bushing 223, making it less likely for the aluminum alloy handle 222 to fall off upwards after it is snapped together with the handle bushing 223, thus improving the firmness of the connection between the two. At the same time, after the rear wall surface of the top rear part of the aluminum alloy handle 222 is snapped together with the rear wall surface of the top rear part of the handle bushing 223, the third buckle 2224 on the second flange 2223 of the aluminum alloy handle 222 further engages with the third step 2236 on the handle bushing 223, which can further improve the connection stability between the handle bushing 223 and the aluminum alloy handle 222, and significantly reduce the probability of the aluminum alloy handle 222 and the handle bushing 223 shaking after they are snapped together.
[0047] Example 3: Reference Figure 10 and Figure 11 This application discloses a door body, which differs from embodiment two in that: Furthermore, multiple reinforcing ribs 2237 are provided between the rear wall surface and the front wall surface of the rear top of the handle liner 223.
[0048] Therefore, the setting of multiple reinforcing ribs 2237 can improve the shaping strength of the second flange 2223 and the handle bushing 223 body, ensure the snap-fit stability of the second step 2235 and the second buckle 2222 and the snap-fit stability of the third step 2236 and the third buckle 2224, and thus ensure the long-term effectiveness of the snap-fit between the rear wall of the aluminum alloy handle 222 and the rear wall of the handle bushing 223.
[0049] The implementation principle of a door in this application embodiment is as follows: When assembling the door panel, the aluminum alloy handle 222 and handle bushing 223 can be assembled first, so that a panel slot 221 is formed on the side of the handle assembly 22 near the metal panel 21, and the plastic handle bushing 223 and the metal aluminum alloy handle 222 are fixedly connected. Then, the first flange 211 on the metal panel 21 is inserted into the panel slot 221 on the handle assembly 22, so that the metal panel 21 and the aluminum alloy handle 222 can be conveniently connected. Moreover, since the metal panel 21 has a U-shaped structure with open top and bottom ends and rear, the connection point after the first flange 211 and the handle assembly 22 are inserted can limit the aluminum alloy handle 222 in the horizontal and vertical directions, so that the assembled aluminum alloy handle 222 and the metal panel 21 are not easy to misalign, separate or fall off, and the aluminum alloy handle 222 and the metal panel 21 can be fixedly connected for a long time. Moreover, the visible surfaces of this door 2 are all made of metal, which greatly enhances the high-end feel of the refrigerator 100 door 2.
[0050] Furthermore, when the first flange 211 on the metal panel 21 is inserted into the panel slot 221 between the first step 2231 and the aluminum alloy handle 222, the first buckle 2221 on the aluminum alloy handle 222 is engaged with the first through hole 2233 in the first step 2231 on the handle bushing 223. This enables a stable connection between the handle bushing 223 and the front of the aluminum alloy handle 222, and evenly controls the gap of the control slot 221, improving the stability of the connection between the metal panel 21 and the aluminum alloy handle 222 and the handle bushing 223, and preventing local warping. Furthermore, after the multiple second buckles 2222 set on the inner side of the rear wall of the aluminum alloy handle 222 are engaged with the second buckles 2222 on the rear wall of the handle bushing 223, a stable connection can be made between the back of the aluminum alloy handle 222 and the handle bushing 223. Together with the engagement connection of the first buckle 2221 and the first through hole 2233, a stable connection of the aluminum alloy handle 222 and the handle bushing 223 as a whole is achieved, resulting in a higher degree of fit between the two. Moreover, the engagement connection between the aluminum alloy handle 222 and the handle bushing 223 does not require the use of screws for fixing, avoiding the possibility of fasteners rusting, and also ensuring the clean appearance of the aluminum alloy handle 222.
[0051] Furthermore, the second flange 2223 can limit the lower edge of the rear wall of the handle bushing 223, making it less likely for the aluminum alloy handle 222 to fall off upwards after it is snapped into place, thus improving the firmness of the connection between the two. At the same time, after the rear wall of the aluminum alloy handle 222 is snapped into place with the rear wall of the handle bushing 223, the third buckle 2224 on the second flange 2223 of the aluminum alloy handle 222 further engages with the third step 2236 on the handle bushing 223, which can further improve the connection stability between the handle bushing 223 and the aluminum alloy handle 222, and significantly reduce the probability of the aluminum alloy handle 222 and the handle bushing 223 shaking after they are snapped into place.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
