[0002] The drive structure of a garment handling device (such as a common washing machine) typically includes a motor and a support frame (such as a tripod). The support frame is connected to the garment handling drum, and the motor drives the support frame to rotate, thereby driving the garment handling drum to rotate, ultimately realizing the washing and spin-drying functions of the garment handling device.
[0003] However, in related technologies, tripods are usually composed of a support body and inserts embedded in the support body. A positioning structure needs to be designed in the support body and the inserts need to be riveted to the body after positioning. The connection method is complicated, inefficient and costly.

[0049] This application provides a support frame and a clothing processing device that can improve the corrosion resistance of the support frame, thereby increasing its strength.
[0050] Specifically, please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the clothing processing tube 20 and the support frame 10 provided in the embodiments of this application; Figure 2 This is a schematic diagram of the structure of the support frame 10 provided in the embodiments of this application; Figure 3 This is another structural schematic diagram of the support frame 10 provided in the embodiments of this application; Figure 4 A partial structural schematic diagram of the support arm 111 and the connecting part 13 provided in the embodiments of this application; Figure 5 This is a schematic diagram of another part of the connecting part and support arm provided in an embodiment of this application.
[0051] The garment processing device in this embodiment can be a washing machine, a dryer, a garment care machine, etc. The following description will use a washing machine as the garment processing device in this embodiment.
[0052] The garment processing device of this embodiment includes a housing, a garment processing drum 20, and a support frame 10. The housing comprises an outer shell and an internal support structure. The outer shell can be made of engineering plastic, possessing good insulation properties and impact resistance. A control panel for user operation is located on the front of the outer shell, integrating a touchscreen display or multiple operation buttons. Users can select various garment processing programs, such as regular washing, drying, and steam care, via the touchscreen display or by pressing the operation buttons. The user can also start, pause, and stop the program. A door is also provided on the front of the outer shell, used to selectively open or close the opening of the garment processing drum 20.
[0053] The internal support structure can be made of high-strength metal alloy or plastic, providing a stable and robust structure that can reliably support the garment handling drum 20, ensuring its stability during operation. Shock-absorbing connection technology can be used between the internal support structure and the outer shell to effectively reduce vibration and noise generated by the garment handling device during operation.
[0054] In this embodiment, the laundry drum 20 is installed inside the washing machine, for example, on the internal support structure of the machine. The laundry drum 20 can be made of stainless steel to ensure sufficient strength to withstand the centrifugal force generated by high-speed rotation. The laundry drum 20 is generally hollow and cylindrical, and its internal space can be arranged according to washing needs to accommodate different volumes and types of laundry, such as sheets, clothes, and shoes. The inner wall surface of the laundry drum 20 is smoothed to effectively reduce wear and tear on clothes during the washing process.
[0055] In some of these embodiments, such as Figure 1 As shown, the clothes handling drum 20 includes a drum body 21 and a bottom cover 22. One end of the drum body 21 is open to facilitate the insertion and removal of clothes, while the other end is connected to the bottom cover 22 to form a space for accommodating clothes. The clothes handling drum 20 can rotate to realize the washing function of the clothes handling device. Exemplarily, the clothes handling device also includes a motor, which is driven by a support frame 10, which is installed at the bottom cover 22 of the clothes handling drum 20. The transmission connection between the motor and the support frame 10 can be through belt drive or direct connection via coupling, that is, direct or indirect transmission, to ensure that the motor can drive the support frame 10 to rotate, thereby driving the clothes handling drum 20 to rotate stably. During the rotation of the clothes handling drum 20, the clothes are moved from bottom to top; under the action of gravity, the clothes fall from top to bottom. In this way, the clothes are dispersed, tumbled, and their posture changed under the combined action of the clothes handling drum 20 and gravity, thereby realizing the washing function.
[0056] Since the support frame 10 inevitably comes into contact with water and detergent for a long time, the existing one-piece cast aluminum support frame 10 is prone to corrosion under the long-term action of water and detergent, which affects the life and strength of the support frame 10.
[0057] In this regard, this application provides a support frame 10 with high corrosion resistance to improve the lifespan and strength of the support frame 10.
[0058] Specifically, the support frame 10 includes a bracket 11, a connecting shaft 12, and a connecting part 13. The bracket 11 is the main structural part of the support frame 10 and consists of at least three support arms 111. That is, the number of support arms 111 is not limited; it can be three, four, or five, and no specific limitation is made here. For example, the support frame 10 includes three support arms 111, one end of which is connected to the connecting shaft 12. The connection method can be welding, riveting, or other forms. Furthermore, the three support arms 111 are arranged at an angle of approximately 120°, forming a stable triangular shape. This angular distribution allows for even distribution of force, ensuring that the stress borne by each support arm 111 is relatively balanced when bearing the weight of the clothing handling drum 20 and the clothing inside and rotating, thereby ensuring the stability of the overall structure. It can be understood that when more than three support arms 111 are provided, the multiple support arms 111 can be arranged at approximately equal angles. For example, when four support arms 111 are provided, adjacent support arms 111 are arranged at 90°, thereby improving the overall strength of the bracket 11.
[0059] In some implementations, the bracket 11 is made of a rust-resistant material. In one embodiment, the bracket 11 is made of stainless steel, such as 304 stainless steel, 430 stainless steel, or 200 series stainless steel. Chromium in stainless steel spontaneously forms a dense and stable chromium oxide passivation film on its surface, effectively preventing water, detergents, and other potentially corrosive substances in the garment processing device from contacting the internal metal substrate. This allows the bracket 11 to maintain good corrosion resistance even in the long-term humid environment of the washing machine, where it is exposed to various chemical detergents, greatly reducing the possibility of corrosion and ensuring the strength and stability of the bracket 11. Simultaneously, stainless steel has relatively high toughness and plasticity, making it easy to manufacture the support frame 10 into the required shape through stamping, bending, and other processing techniques, thus facilitating manufacturing.
[0060] In another embodiment, the outer surface of the bracket 11 has a rust-proof coating, which can be selected from a zinc plating coating, a paint coating, and a phosphate coating to achieve the rust-proof function.
[0061] The zinc coating is applied to the surface of the bracket 11 by hot-dip galvanizing or electro-galvanizing. The zinc layer is tightly bonded to the base metal, forming a continuous covering. In the humid and chemically-laden environment of the washing machine, zinc has a lower electrode potential than base metals such as iron, and will preferentially corrode. Acting as a sacrificial anode, zinc protects the base metal bracket 11, effectively delaying the corrosion of the base metal and improving the overall corrosion resistance of the bracket 11.
[0062] Paint coatings are typically made of epoxy paint, polyurethane paint, etc., and consist of various components such as film-forming substances, pigments, and solvents. After the paint coating is applied to the surface of the bracket 11, it undergoes drying and curing processes to form a continuous and dense protective film, which isolates the bracket 11 from the outside air, moisture, and corrosive substances such as detergents that may come into contact with it, thereby achieving the purpose of rust prevention.
[0063] The phosphate coating is achieved through chemical phosphating, where a phosphating solution containing phosphoric acid and phosphates reacts chemically with the metal surface of the support 11 to form a phosphate conversion film, also known as the phosphate film. The phosphate film has a porous structure, which provides a good adhesion foundation for subsequent coating processes and also enhances the rust resistance of the metal, thus improving the corrosion resistance of the support 11.
[0064] In this embodiment, the connecting shaft 12 is connected to the junction of the three support arms 111. The connecting shaft 12 serves as the central rotating shaft 122 of the entire support frame 10. Driven by a power device such as a motor, it drives the entire support frame 10 to rotate, thereby driving the clothing processing drum 20 to rotate.
[0065] In some embodiments, the connecting shaft 12 includes a bushing 121 and a rotating shaft 122. The bushing 121, as the part of the connecting shaft 12 structure directly connected to the support arms 111 of the support frame 10, is welded to the junction of the three support arms 111. The rotating shaft 122 passes through the bushing 121, and the size of the rotating shaft 122 precisely matches the inner diameter of the bushing 121. The two can be connected by an interference fit, welding, or screws. One end of the rotating shaft 122 is connected to a power source (such as a motor, connected to the rotating shaft 122 via belt drive, coupling, or other transmission methods) to receive power from the motor, thereby driving the entire support frame 10 and the clothes processing drum 20 to rotate, realizing the washing and dehydration functions of the clothes processing device. The connecting shaft 12 can be made of the same material as the bracket 11, which will not be described further here.
[0066] In this embodiment, the connecting part 13 is used to connect the support frame 10 and the clothing processing tube 20. The connecting part 13 is connected to at least one side wall 110 of the support arm 111 away from the connecting shaft 12, which is simple, efficient and low cost.
[0067] Specifically, the connecting part 13 can be made of the same material as the support arm 111 to ensure sufficient strength and corrosion resistance. The connection method between the connecting part 13 and the support arm 111 can include welding, riveting, screw connection, etc. In one embodiment, the connecting part 13 is welded to at least one side wall 110 of the support arm 111 at the end away from the connecting shaft 1212. This welding method makes the welding operation relatively intuitive and convenient. In addition, compared with the prior art method of embedding the connecting part 13 on the inner side of the far end of the support arm 111, the welding method requires the connecting part 13 to be positioned first, and then connected to the far end of the support arm 111 by riveting after positioning. This not only involves many processes, but if the positioning is inaccurate, it will affect the reliability of the subsequent connection between the connecting part 13 and the clothing treatment tube 20. The welding method used in this application is simple to manufacture, has lower cost, and more reliable performance. The shape of the connecting part 13 can be block-shaped, such as a regular block such as a cuboid or cube, or other irregular blocks, or it can be formed by bending a plate.
[0068] The side wall 110 structure of the support arm 111 in this embodiment can have various forms. In one embodiment, such as... Figure 4 As shown, the side wall 110 structure of the support arm 111 includes an upper side wall 1101, a lower side wall 1102, a left side wall 1103, and a right side wall 1104. The connecting part 13 can be connected to any one or more of these four side walls 110. This allows the support frame 10 to adjust the connection method according to the actual structure and stress conditions of the garment processing device to achieve the best support effect. For example, in some garment processing devices, the garment processing drum 20 may generate a large upward impact force during operation. In this case, connecting the connecting part 13 to the upper side wall 1101 of the support arm 111 can more effectively withstand this impact force and ensure the stability of the support frame 10.
[0069] In another embodiment, the sidewall structure of the support arm 111 has an outer wall surface 111a and an inner wall surface 111b. The connecting portion 13 can be connected to either the outer wall surface 111a or the inner wall surface 111b of the support arm 111.
[0070] In one implementation, such as Figure 8As shown, the end of the support arm 111 away from the connecting shaft 12 has a flange 1112, which is located on both sides of the support arm 111 in the width direction. The connecting part 13 is connected to the inside of the flange 1112. This connection method can make full use of the structure of the flange 1112, increasing the stability and reliability of the connection. The presence of the flange 1112 not only provides additional connection area, but also changes the force transmission path, making the force more evenly distributed on the support arm 111. For example, the centrifugal force generated during the rotation of the garment processing drum 20 is transmitted to the inside of the flange 1112 through the connecting part 13, and then evenly distributed to other parts of the support arm 111 by the flange 1112, avoiding local stress concentration.
[0071] In another embodiment, the end of the support arm 111 away from the connecting shaft 12 has a mounting groove, and the connecting part 13 extends into the mounting groove and connects to the inner wall surface 111b of the mounting groove. This connection method makes the connection between the connecting part 13 and the support arm 111 tighter, and the inner wall surface 111b of the mounting groove can provide good support for the connecting part 13, preventing the connecting part 13 from shifting or shaking when subjected to force.
[0072] In this embodiment, the connecting part 13 is directly connected to at least one side wall 110 of the support arm 111. Compared with the traditional method of setting complex positioning structures on the bracket 11, this connection method eliminates the need to process additional positioning holes, positioning cavities, or other structures on the bracket 11, greatly simplifying the manufacturing process. Reducing processing steps not only shortens the production cycle but also reduces errors that may arise from complex processing, thus improving the product yield. Simultaneously, since no additional positioning structures are required, manufacturing costs are reduced.
[0073] In one embodiment, at least a portion of the connecting portion 13 is disposed on the outer side of the end of the support arm 111 away from the connecting shaft 12, and the connecting portion 13 partially overlaps the support arm 111 along the width direction of the support arm 111. The fact that the connecting portion 13 is disposed on the outer side of the end of the support arm 111 away from the connecting shaft 12 reduces the positioning or connection between the connecting portion 13 and the support arm 11, making this connection method simpler and easier to implement. The outer side of the support arm 111 referred to here refers to the outer wall surface 111a of the support arm 111. For example, as shown... Figure 8 As shown, the cross-section of the support arm 111 is U-shaped, and the outer wall surface 111a consists of the outer surfaces of the upper side wall 1101, lower side wall 1102, left side wall 1103, and right side wall 1104. The overlapping arrangement means that the connecting part 13 and the support arm 111 at least partially overlap in the width direction of the support arm 111. This overlapping arrangement increases the contact area between the connecting part 13 and the support arm 111, allowing the force generated by the clothing handling drum 20 during operation to be more evenly distributed on the support arm 111, avoiding excessive local stress, and thus improving the stability and reliability of the connection.
[0074] In this embodiment, the connecting part 13 can be disposed on the outer wall surface 111a or the inner wall surface 111b of the end of the support arm 111 away from the connecting shaft 12, as long as they overlap. When the connecting part 13 is disposed on the outer wall surface 111a of the support arm 111, the processing and installation process is relatively intuitive and convenient. When the connecting part 13 is disposed on the inner wall surface 111b of the support arm 111, it can better protect the connecting part 13 from the influence of the external environment and extend the service life of the connecting part 13.
[0075] Please see Figure 4 and Figure 6 , Figure 6 This is a schematic diagram of the structure of the connecting part 13 provided in an embodiment of this application.
[0076] In one embodiment, the connecting portion 13 has a mounting space 1301, which may be a mounting cavity or mounting groove formed in the connecting portion 13. At least one end of the support arm 111, away from the connecting shaft 12, extends into the mounting space 1301, and at least one outer wall surface 111a of the support arm 111 is connected to the connecting portion 13. When the support arm 111 extends into the mounting space 1301, the connecting portion 13 can effectively limit the displacement of the support arm 111 in all directions through its connection with the outer wall surface 111a of the support arm 111, thereby enhancing the stability of the connection. Simultaneously, the presence of the mounting space 1301 can also protect the connecting portion 13 of the support arm 111 to a certain extent, reducing the impact of external factors on the connection.
[0077] For example, when the mounting space 1301 is a mounting cavity, after the support arm 111 extends into the mounting cavity, the inner wall of the mounting cavity is tightly fitted with the outer wall surface 111a of the support arm 111. The two are fixed together by welding, riveting, or bolting, so that the force can be transmitted more evenly from the support arm 111 to the connection part 13, avoiding stress concentration and improving the reliability of the connection. If the mounting space 1301 is a mounting groove, at least a part of the structure of the support arm 111 extends into the mounting groove, and the inner wall of the mounting groove is connected to the outer wall surface 111a of the support arm 111, which can also achieve a stable connection effect.
[0078] In one embodiment, the connecting part 13 includes a connecting body 131 and a connecting post 132. The connecting body 131 has the aforementioned mounting space 1301, and the connecting body 131 can be formed by integral casting or by connecting several plates.
[0079] In this embodiment, the connecting post 132 is installed within the installation space 1301. The connecting post 132 has a connecting hole 1321, which can be a threaded hole. The connecting post 132 is used to connect the support arm 111 to the clothing processing cylinder 20. In practical applications, fasteners (such as bolts or screws) are screwed into the connecting hole 1321 of the connecting post 132 to securely connect the support frame 10 to the clothing processing cylinder 20. The connection method is simple and reliable, easy to install and disassemble, and can effectively transmit force, ensuring the stability of the clothing processing cylinder 20 during operation.
[0080] In one embodiment, the connecting body 131 includes a back plate 1311 and at least two side plates 1312. The back plate 1311 and the side plates 1312 together form a mounting space 1301 for the end portion of the support arm 111 away from the connecting shaft 12 to extend into. The side plates 1312 are connected to the periphery of the back plate 1311, and the connection method can be welding, riveting, bending, etc. The number and connection method of the side plates 1312 can include several methods to meet different usage requirements.
[0081] In one embodiment, the two side plates 1312 of the connecting body 131 are arranged opposite to each other and are both connected to the outer wall surface 111a of the support arm 111. The two side plates 1312 can be arranged opposite each other left and right or top and bottom. This arrangement allows the support arm 111 to be constrained by the two opposite side plates 1312 in the horizontal or vertical direction, effectively limiting the displacement and sway of the support arm 111 in that direction. In the connection method, the side plates 1312 can be firmly connected to the outer wall surface 111a of the support arm 111 by welding, riveting, or bolting.
[0082] In one embodiment, four side plates 1312 are provided. These four side plates 1312 are connected to the periphery of the back plate 1311 and together with the back plate 1311, form an installation space 1301. Each side plate 1312 is connected to the outer wall surface 111a of the support arm 111. This provides more comprehensive constraint and support. The four side plates 1312 fix the support arm 111 from different angles, greatly restricting the degree of freedom of the support arm 111 in three-dimensional space. During the operation of the garment handling drum 20, whether it is gravity in the vertical direction, centrifugal force in the horizontal direction, or vibration and impact forces in other directions, they can be evenly distributed to the connecting body 131 through the four side plates 1312, further enhancing the reliability of the connection.
[0083] In one embodiment, the arrangement of two adjacent side plates 1312 is also different.
[0084] In one embodiment, adjacent side plates 1312 can be spaced apart. On the one hand, spaced-apart side plates 1312 provide more operating space for the installation and adjustment of the support arm 111, facilitating fine-tuning during assembly. On the other hand, a certain gap is left between adjacent side plates 1312. The connecting part 13 may undergo slight deformation under stress, and the spaced design provides additional deformation space for the connecting part 1313, avoiding excessive stress concentration.
[0085] In one embodiment, two adjacent side plates 1312 can also be connected to each other. The connection method can be welding, riveting, bending, etc. The connected side plates 1312 form a continuous structure, which enhances the overall rigidity and strength of the connecting body 131.
[0086] Please see Figure 7 , Figure 7 This is a cross-sectional side view of the connecting part 13 and the support arm 111.
[0087] In one embodiment, such as Figure 1 As shown, the connection between the connecting part 13 and the clothing processing tube 20 can be achieved through fasteners, such as screws or bolts.
[0088] In one embodiment, the garment processing tube 20 is composed of a tube body 21 and a tube bottom cover 22, wherein the tube body 21 has a protruding edge 211 protruding from the tube bottom cover 22.
[0089] In one embodiment, the connecting part 13 is provided with at least one connecting hole 1321, which is used to connect the connecting part 13 to the clothing processing tube 20. For example, the fastener passes through the protruding edge 211 and the connecting hole 1321 in sequence to achieve a tight connection between the connecting part 13 and the clothing processing tube 20.
[0090] In one embodiment, the extended axis of the connecting hole 1321 intersects the axis of the garment processing drum 20. Specifically, the connecting part 13 is connected to the protruding edge 211 of the garment processing drum 20, and the extended axis of the connecting hole 1321 is substantially perpendicular to the axis of the garment processing drum 20, with an angle of 90°±10°. Thus, during the rotation of the garment processing drum 20, the centrifugal force it generates will have different effects depending on the setting angle of the axis of the connecting hole 1321. Compared to a connection method where the axis of the connecting hole 1321 is parallel to the axis of the garment processing drum 20, this embodiment can optimize the force state of the connecting part 13 by utilizing the principle of force decomposition. When the garment processing drum 20 rotates at high speed and generates centrifugal force, this centrifugal force can be decomposed into a component force perpendicular to the connection surface between the connecting part 13 and the garment processing drum 20 and a component force along the tangential direction of the connection surface. The vertical component force has a pressing effect on the connection between the connecting part 13 and the garment processing drum 20, increasing the friction between the two and effectively preventing relative sliding of the connecting part 13. For example, during the spin-drying process of the washing machine, the clothes processing drum 20 rotates at high speed and generates a large centrifugal force. At this time, the vertical component of the force significantly increases the friction between the connecting part 13 and the protruding edge 211 of the clothes processing drum 20, ensuring that the connecting part 13 will not be displaced due to the centrifugal force.
[0091] While the component of the force along the tangent direction of the connection surface generates a tensile force on the connection part 13, the structural design of the connection part 13 is more suitable for withstanding this type of axial tensile force. When a bolted connection is used, the axial tensile strength of the bolt can effectively resist this component of the force. Compared with parallel connections where the bolt mainly bears shear force, the reliability of the connection is greatly improved.
[0092] In some implementations, the end face of the connecting portion 13 away from the support arm 111 is configured as an arc-shaped surface, which matches the connecting surface of the garment processing tube 20. Specifically, the protruding edge 211 of the garment processing tube 20 has an arc-shaped connecting surface, and the arc-shaped surface of the connecting portion 13 can fit tightly against the connecting surface of the protruding edge 211. This fitting method greatly increases the contact area between the connecting portion 13 and the garment processing tube 20. Compared with the traditional planar connection method, when the arc-shaped surface is fitted, the contact points are more evenly distributed, making the force transmission more stable and the connection more secure.
[0093] In some implementations, the edge of the connecting hole 1321 at the end away from the support arm 111 is set as a bevel. The bevel design has a centering function and facilitates the installation of fasteners.
[0094] The presence of this bevel allows the fastener to be automatically adjusted to a certain extent during assembly, even if there is a certain positional deviation, so that it can better match the connecting hole 1321 and reduce connection problems caused by assembly errors.
[0095] Please see Figure 8 , Figure 8 This is a schematic diagram of the support frame 10 after being cut open along the cross-section of a support arm 111, as provided in an embodiment of this application.
[0096] In this embodiment, the upper surface portion of the support arm 111 protrudes upward to form a protrusion 1111, and the length of the protrusion 1111 is the same as the length of the support arm 111.
[0097] The protrusion 1111 can be formed through a bending process. The protrusion 1111 formed by the bending process can significantly increase the strength of the support arm 111. From the perspective of mechanical principles, when the washing machine is running, the support frame 10 bears external forces such as the gravity of the clothes handling drum 20 and the centrifugal force generated by rotation. The protrusion 1111 is equivalent to adding a three-dimensional reinforcing structure to the planar structure of the support arm 111, thereby improving the overall strength of the support arm 111.
[0098] Furthermore, the upper surface of the protrusion 1111 is a smooth surface. During assembly, the support frame 10 needs to be placed in the mounting groove of the bottom cover 22. When the smooth protrusion 1111 on the support arm 111 contacts the inner wall of the mounting groove of the bottom cover 22, the smooth surface can minimize the unevenness and gaps of the surface, allowing the two to make close contact, thereby helping to improve the stability of the entire assembly structure.
[0099] In some embodiments, the support arm 111 has flanges 1112 on both sides of its width direction, and the two flanges 1112 are located on both sides of the protrusion 1111. The flange structure 1112 can also improve the strength of the support arm 111. From a structural mechanics perspective, the flanges 1112 on both sides of the support arm 111 are equivalent to adding additional reinforcing ribs, which can effectively resist the external forces borne by the support arm 111 in the width direction, such as the lateral forces generated during the rotation of the clothing handling drum 20 and the lateral forces caused by possible eccentricity.
[0100] In some embodiments, in the width direction of the support arm 111, the width of the protrusion 1111 is equal to the sum of the distances from the two flanges 1112 to the protrusion 1111, i.e., L = L1 + L2 (L represents the width of the protrusion 1111, L1 represents the distance from one flange 1112 to the protrusion 1111, and L2 represents the distance from the other flange 1112 to the protrusion 1111). This dimensional relationship, on the one hand, ensures a more reasonable and balanced force distribution among the various components of the support arm 111 from a structural strength perspective. The arrangement of the protrusion 1111 and flanges 1112 according to the aforementioned proportional relationship allows the entire support arm 111 to evenly distribute the force to various parts for bearing load when subjected to external forces, fully utilizing the strength-enhancing effects of the protrusion 1111 and flanges 1112, and preventing structural damage due to excessive force on any one part.
[0101] On the other hand, from an aesthetic point of view, the aforementioned size limitation makes the overall shape of the support arm 111 more regular and harmonious, giving people a simple and symmetrical beauty, which meets the requirements of modern home appliances for exquisite and beautiful appearance design.
[0102] Furthermore, the cross-sectional shape of the support arm 111 is axially symmetrical about the centerline of the protrusion 1111, and the cross-sectional shape is approximately "U"-shaped. This axially symmetrical structure gives the support arm 111 better symmetry and stability under stress. Regardless of the direction from which external force acts on the support arm 111, the corresponding structures on its left and right sides can evenly distribute and transfer stress about the centerline of the protrusion 1111 as the axis of symmetry, avoiding problems such as uneven stress and localized deformation that may occur due to structural asymmetry.
[0103] Furthermore, the width of the support arm 111 gradually decreases in the direction from the connecting shaft 12 toward the connecting portion 13. In this embodiment, the support arm 111, while ensuring sufficient strength to withstand the various forces acting on the garment handling tube 20, effectively saves material by gradually varying its width. At the end near the connecting shaft 12, where it primarily bears the torque transmitted from the connecting shaft 12 and distributes the force throughout the support arm 111, the width requirement is relatively high, so the initial width of the support arm 111 is relatively large. As it extends toward the connecting portion 13, the force is gradually dispersed and transmitted, and the width requirement for the support arm 111 decreases accordingly, thus its width gradually decreases.
[0104] The aforementioned gradually narrowing support arm 111 structure not only does not weaken the overall strength of the support arm 111, but also reduces the amount of material used and lowers production costs while meeting mechanical performance requirements through reasonable structural optimization, and also reduces the overall weight of the support frame 10.
[0105] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
