[0002] With the continuous updating of clothing processing equipment, users have also put forward higher and higher requirements for the comprehensive performance of clothing processing equipment. In recent years, some clothing processing equipment has been able to process some high-end items, such as high-end leather goods. Since these items can easily be damaged by the wall of the drum when placed directly in the clothing processing drum for processing, various clothing processing racks have come into being. Although there are many types of clothing processing racks, most of them are used in pulsator-type clothing processing equipment, which requires that the clothing processing drum must be set vertically. However, clothing processing racks for drum-type clothing processing equipment are very rare. Even if there are a few clothing processing racks that can be used in drum-type clothing processing equipment, they can only be placed in the clothing processing drum of drum-type clothing processing equipment for use. However, the existing direct-drive drum-type clothing processing equipment needs to rotate slightly during the process of processing clothes.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] See first Figure 1 、 2 and 3, where Figure 1 This is a schematic diagram of the overall structure of the support frame of the present invention when used in a direct-drive drum-type clothes processing device; Figure 2 This is a partial structural diagram of the support frame of the present invention when used in a direct-drive drum-type clothes processing device; Figure 3 FIG is a schematic diagram of the overall structure of a preferred embodiment of the support frame of the present invention. Figures 1 to 3 As shown, the direct-drive drum type clothing processing device described in this preferred embodiment includes a body and an outer drum, an inner drum 2 and a direct-drive motor arranged in the body, wherein the inner drum 2 is rotatably arranged in the outer drum, and the driving shaft of the direct-drive motor is directly connected to the inner drum 2 so that the direct-drive motor can directly drive the inner drum 2 to rotate, and three water-dispelling blades 21 are arranged on the inner side wall of the inner drum 2. It should be noted that the present invention does not impose any restrictions on the specific structure of the direct-drive drum type clothing processing device, and technicians can set it according to actual use requirements; for example, the direct-drive motor can drive the inner drum 2 to rotate a full circle, or drive the inner drum 2 to rotate back and forth within a small range; for another example, the water-dispelling blades 21 on the inner side wall of the inner drum 2 can be three or more than three; these changes in the specific structure of the direct-drive drum type clothing processing device do not deviate from the basic principles of the present invention.

[0037] Continue reading Figure 3The support frame 1 of the present invention includes a first support plate 11, a second support plate 12, a first connecting shaft 13 fixedly connected to the inner end of the first support plate 11 (i.e., the end close to the second support plate 12), and a second connecting shaft 14 fixedly connected to the inner end of the second support plate 12 (i.e., the end close to the first support plate 11). The first connecting shaft 13 and the second connecting shaft 14 are rotatably connected so that the first support plate 11 and the second support plate 12 can be folded relative to each other, thereby changing the lateral dimension of the support frame 1 (i.e., the direction perpendicular to the first connecting shaft 13 and the second connecting shaft 14) so ​​that the support frame 1 can be placed in the inner tube 2 in a folded state and is more convenient for users to store. It should be noted that the present invention does not impose any restrictions on the specific connection method of the first connecting shaft 13 and the second connecting shaft 14. Technicians can set it according to actual use requirements, as long as the first connecting shaft 13 and the second connecting shaft 14 can rotate relative to each other so that the first support plate 11 and the second support plate 12 can be folded relative to each other. At the same time, a locking device 15 is provided between the first connecting shaft 13 and the second connecting shaft 14. The locking device 15 can selectively limit the relative rotation of the first connecting shaft 13 and the second connecting shaft 14 and, when limiting, enables the outer end of the first support plate 11 (i.e., the end away from the second support plate 12) and the outer end of the second support plate 12 (i.e., the end away from the first support plate 11) to respectively abut against the bottom of the two water-dispelling blades 21 to achieve the overall fixation of the support frame 1. It should be noted that the two water-dispelling blades 21 used to abut against the support frame 1 can be either two adjacent water-dispelling blades or two non-adjacent water-dispelling blades, and the specific selection method can be flexibly set by the number and arrangement method of the water-dispelling blades 21. In addition, it should be noted that the present invention does not impose any restrictions on the specific structure of the locking device 15. Technicians can set it according to actual usage requirements, as long as the locking device 15 can selectively limit the relative rotation of the first connecting shaft 13 and the second connecting shaft 14 and enable the outer ends of the first support plate 11 and the second support plate 12 to respectively abut against the bottoms of the two water-dispelling blades 21 when limiting to achieve overall fixation of the support frame 1.

[0038] Next see Figure 4 , which is a schematic structural diagram of the first support plate and the second support plate of the present invention. Figure 4As shown, in this preferred embodiment, a first sleeve structure 111 is provided at the inner end of the first support plate 11, and the axial length of the first sleeve structure 111 is half of the width of the support frame 1 (that is, the axial length along the inner cylinder 2 when the support frame 1 is fixed in the inner cylinder 2), and the inner wall of the first sleeve structure 111 is formed with a first step (not shown in the figure) so that the first connecting shaft 13 can be fixed through the first step; at the same time, a second sleeve structure 121 is provided at the inner end of the second support plate 12, and the axial length of the second sleeve structure 121 is also half of the width of the support frame 1, and the inner wall of the second sleeve structure 121 is formed with a second step (not shown in the figure) so that the second connecting shaft 14 can be fixed through the second step. When the support frame 1 is assembled in place, the axis of the first sleeve structure 111 arranged on the first support plate 11 and the axis of the second sleeve structure 121 arranged on the second support plate 12 coincide with each other, and the axial lengths of the first sleeve structure 111 and the second sleeve structure 121 are exactly the same as the width of the support frame 1, so as to better ensure the stability of the support frame 1 and the reliability of rotation.

[0039] It should be noted that although the inner end of the first support plate 11 described in this preferred embodiment is provided with a first sleeve structure 111 and the inner end of the second support plate 12 is provided with a second sleeve structure 121, this is not a restrictive structural setting. Technicians can also use other fixing structures to fix the first connecting shaft 13 and the second connecting shaft 14 according to actual use requirements, as long as the first support plate 11 is fixedly connected to the first connecting shaft 13 and the second support plate 12 is fixedly connected to the second connecting shaft 14. For example, technicians can also provide a mounting ring on the first support plate 11 and then fix the first connecting shaft 13 in the connecting ring to achieve a fixed connection. Such changes in the specific fixing method do not deviate from the basic principles of the present invention and fall within the scope of protection of the present invention.

[0040] Next see Figures 5 to 7 ,in, Figure 5 It is a schematic diagram of the overall structure of the first connecting shaft, the second connecting shaft and the locking device of the present invention; Figure 6 is a cross-sectional view of the first connecting shaft, the second connecting shaft and the locking device of the present invention; Figure 7 : is an exploded view of the first connecting shaft, the second connecting shaft and the locking device of the present invention. Figures 5 to 7 As shown, in this preferred embodiment, refer to Figures 5 to 7In the orientation, the second connecting shaft 14 includes a first shaft section 141 (i.e., the right shaft section) and a second shaft section 142 (i.e., the left shaft section). The radial dimension of the first shaft section 141 is smaller than the radial dimension of the second shaft section 142, so that the second connecting shaft 14 has a stepped shaft structure. The axis of the first connecting shaft 13 is provided with a receiving through hole 131. The aperture of the receiving through hole 131 is the same as the outer diameter of the first shaft section 141, so that the first shaft section 141 can be inserted into the receiving through hole 131, that is, the first connecting shaft 13 is sleeved outside the first shaft section 141. At the same time, the right end of the first connecting shaft 13 is provided with a first fixing ring 132, and the first fixing ring 132 is also formed with a mounting notch. The left end of the second shaft section 142 is provided with a second fixing ring 143, and the second fixing ring 143 is also formed with a mounting notch. In addition, a mounting hole 144 is formed on the right end face of the second connecting shaft 14. It should be noted that the present invention does not impose any limitation on the specific structure of the first connecting shaft 13 and the second connecting shaft 14. Those skilled in the art can set it according to actual use requirements, as long as the first connecting shaft 13 and the second connecting shaft 14 can be rotatably connected.

[0041] Based on the structure of the first support plate 11, the second support plate 12, the first connecting shaft 13 and the second connecting shaft 14 described in the above preferred embodiment, when assembling the support frame 1, the inner end of the first connecting shaft 13 (i.e. Figure 7 The left end of the first sleeve structure 111) is from the outer end (ie Figure 4 The upper end of the sleeve 111 extends into the first sleeve structure 111 and extends out of the inner end of the first sleeve structure 111 (i.e. Figure 4 The lower end of the second connecting shaft 14 (ie Figure 7 The right end of the second sleeve structure 121) Figure 4 The lower end of the second sleeve structure 121 extends into the inner end (i.e. Figure 4The upper end of the connecting shaft 11 is inserted into the upper end of the connecting shaft 12, and the first shaft section 141 of the second connecting shaft 14 is inserted into the receiving through hole 131 provided on the first connecting shaft 13. Finally, the mounting bolt 18 is passed through the mounting gasket 17 and fixed to the mounting hole 144, so that the first connecting shaft 13 and the second connecting shaft 14 are fixed to each other in the axial direction, so that the first support plate 11 and the second support plate 12 are connected through the first connecting shaft 13 and the second connecting shaft 14. When the support frame 1 is assembled in place, when the first connecting shaft 13 rotates relative to the first shaft section 141 of the second connecting shaft 14, the first support plate 11 can also rotate relative to the second support plate 12, so that the first support plate 11 and the second support plate 12 can fold each other; the first fixing ring 132 arranged on the first connecting shaft 13 cooperates with the first step formed on the inner wall of the first sleeve structure 111, and a better fixed connection is achieved through the installation notch formed on the first fixing ring 132, so that the first connecting shaft 13 is fixedly connected to the first support plate 11; the second fixing ring 143 arranged on the second connecting shaft 14 cooperates with the second step formed on the inner wall of the second sleeve structure 121, and a better fixed connection is achieved through the installation notch formed on the second fixing ring 143, so that the second connecting shaft 14 is fixedly connected to the second support plate 12.

[0042] Furthermore, the locking device 15 includes a sliding ring 151 and a spring 152 that are slidably mounted on the outside of the first connecting shaft 13. The two ends of the spring 152 are respectively connected to the shaft shoulder of the first connecting shaft 13 and the right end surface of the sliding ring 151. Three axial sliding grooves 133 are provided on the left half of the first connecting shaft 13, and three axial sliding protrusions 1513 are correspondingly formed on the inner wall of the sliding ring 151. The sliding ring 151 is slidably connected to the first connecting shaft 13 via the sliding protrusions 1513, effectively ensuring that only axial sliding occurs between the sliding ring 151 and the first connecting shaft 13 without circumferential rotation. The sliding ring 151 can compress the spring 152 during the sliding process, causing deformation. When the sliding ring 151 moves to the locked position, the spring 152 can press the sliding ring 151 tightly to ensure reliable locking. It should be noted that although the elastic member described in this preferred embodiment is a spring 152, this is not restrictive. The elastic member can also be other elastic structures, such as an elastic ring.

[0043] Furthermore, in this preferred embodiment, a locking notch 1511 is provided at the left end of the sliding ring 151, and a corresponding locking protrusion 145 is provided on the second connecting shaft 14. The shape of the locking notch 1511 matches the shape of the locking protrusion 145, so that the locking device 15 is locked through the locking notch 1511 and the locking protrusion 145, thereby restricting relative rotation between the first connecting shaft 13 and the second connecting shaft 14. Specifically, based on the above structure, when the sliding ring 151 slides leftward to the locking position, the locking notch 1511 and the locking protrusion 145 engage with each other, thereby restricting relative rotation between the first connecting shaft 13 and the second connecting shaft 14. When the sliding ring 151 slides rightward to the unlocking position, the locking notch 1511 and the locking protrusion 145 separate from each other, allowing relative rotation between the first connecting shaft 13 and the second connecting shaft 14.

[0044] Furthermore, a limiting protrusion 134 is provided on the first connecting shaft 13. During the relative rotation of the first connecting shaft 13 and the second connecting shaft 14, the limiting protrusion 134 and the locking protrusion 145 are always located on the same circumference. Based on this, during the rotation of the first connecting shaft 13, the two side surfaces of the limiting protrusion 134 provided on the first connecting shaft 13 can respectively abut against the two side surfaces of the locking protrusion 145, thereby limiting the relative rotation range of the first connecting shaft 13 and the second connecting shaft 14. Moreover, technicians can also limit the relative rotation range of the first connecting shaft 13 and the second connecting shaft 14 by setting the circumferential dimensions of the limiting protrusion 134 and the locking protrusion 145. It will be understood by those skilled in the art that this limiting method is not restrictive and that technicians can also use other limiting devices to limit the relative rotation range of the first connecting shaft 13 and the second connecting shaft 14.

[0045] Continue reading Figure 4 and Figure 5 The inner end of the first sleeve structure 111 is provided with a first notch 1111, the inner end of the second sleeve structure 121 is provided with a second notch 1211, and the sliding ring 151 is also provided with an operating handle 1512; when assembled, the first notch 1111 and the second notch 1211 are connected to each other and form a sliding opening for the operating handle 1512 to slide. The operating handle 1512 can slide in the sliding opening so that the sliding ring 151 can slide on the first connecting shaft 13, so that the user can control the sliding of the sliding ring 151 through the operating handle 1512, thereby effectively ensuring the convenience of operation. It should be noted that the present invention does not impose any restrictions on the specific shapes of the first notch 1111 and the second notch 1211, as long as the operating handle 1512 can slide in the sliding opening formed by the first notch 1111 and the second notch 1211 to drive the sliding ring 151 to move.

[0046] Based on the above structural setting, when the operating handle 1512 is located between the first notch 1111 and the second notch 1211, that is, when a part of the operating handle 1512 is in the first notch 1111 and the other part is in the second notch 1211, the sliding ring 151 is in the locking position. In this case, the locking notch 1511 and the locking protrusion 145 engage with each other to limit the relative rotation of the first connecting shaft 13 and the second connecting shaft 14; when the operating handle 1512 slides in the direction close to the first connecting shaft 13 until the operating handle 1512 is completely in the first notch 1111, the sliding ring 151 slides to the non-locking position, and the locking notch 1511 and the locking protrusion 145 separate from each other to allow the first connecting shaft 13 and the second connecting shaft 14 to rotate relative to each other.

[0047] It should be noted that, although in this preferred embodiment, the sliding opening formed by the first notch 1111 and the second notch 1211 only serves to cooperate with the operating handle 1512 to achieve sliding; however, as another preferred embodiment, technicians can also limit the width of the sliding opening formed by the first notch 1111 and the second notch 1211 to limit the width of the sliding opening, so that the operating handle 1512 and the sliding opening are connected by an interference fit, so that the sliding opening can also serve as an auxiliary limiter.

[0048] Furthermore, as a preferred embodiment, a first mounting groove 1112 is further provided at the first notch 1111 of the first sleeve structure 111, the first mounting groove 1112 is formed around the first notch 1111 and is located above the first notch 1111, and forms a step shape with the edge of the first notch 1111, and a second mounting groove 1212 is further provided at the second notch 1211 of the second sleeve structure 121, the second mounting groove 1212 is formed around the second notch 1211 and is located above the second notch 1211, and forms a step shape with the edge of the second notch 1211, the setting of the first mounting groove 1112 and the second mounting groove 1212 can effectively increase the axial dimension, so that the operating handle 1512 can be more easily installed in the sliding opening formed by the first notch 1111 and the second notch 1211, thereby effectively simplifying the assembly process of the support frame 1.

[0049] Continue reading Figure 4In this preferred embodiment, the right end of the first support plate 11 and the left end of the second support plate 12 are both provided with an elastic abutment structure 16, and the elastic abutment structure 16 includes a plurality of elastic connecting strips 161 and abutment strips 162, wherein the abutment strips 162 are arranged along the width direction of the support frame 1 (that is, the axial direction of the inner tube 2 when the support frame 1 is fixed in the inner tube 2), and the length of the abutment strips 162 is the same as the width of the support frame 1, and a rubber strip is preferably provided on the outer side of the abutment strip 162 so that the abutment strip 162 can abut against the bottom of the water-repelling blade 21 more firmly without causing damage to the inner wall of the inner tube 2. At the same time, a plurality of elastic connecting strips 161 are arranged in an inclined manner between the abutment strip 162 and the main body of the support frame 1 (i.e., including the first support plate 11 and the second support plate 12); specifically, the elastic connecting strip 161 of the elastic abutment structure 16 arranged at the right end of the first support plate 11 is arranged in an inclined manner between its corresponding abutment strip 162 and the first support plate 11, and the elastic connecting strip 161 of the elastic abutment structure 16 arranged at the left end of the second support plate 12 is arranged in an inclined manner between its corresponding abutment strip 162 and the second support plate 12. In this preferred embodiment, by providing a plurality of elastic connecting strips 161 to achieve connection, the spacing between the abutment strip 162 and the main body of the support frame 1 can be changed to adapt to different spacings between the two water-repelling blades 21, thereby significantly improving the scope of application of the present invention.

[0050] It should be noted that the present invention does not impose any restrictions on the specific structure of the elastic abutment structure 16. Technicians can customize it according to actual usage requirements. As long as the first support plate 11 and the second support plate 12 can respectively abut the bottom of the corresponding water-repelling blade 21 through their corresponding elastic abutment structures 16 when the support frame 1 is supported in the inner tube 2, it is sufficient. For example, the elastic abutment structure 16 may also include an abutment strip 162 arranged along the width direction of the support frame 1 and a plurality of springs arranged between the body of the support frame 1 and the abutment strip 162. Such changes in the specific structure do not deviate from the basic principles of the present invention and should fall within the scope of protection of the present invention.

[0051] Furthermore, first guardrails 112 are provided on both sides of the first support plate 11 (i.e., the two sides adjacent to the first sleeve structure 111 and the corresponding elastic abutment structure 16), and second guardrails 122 are provided on both sides of the second support plate 12 (i.e., the two sides adjacent to the second sleeve structure 121 and the corresponding elastic abutment structure 16), so as to better protect the items to be processed placed on the support frame 1 to prevent them from falling during the processing process and causing friction with the inner wall of the inner cylinder 2 and causing damage, thereby ensuring the user experience to the greatest extent.

[0052] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
