[0002] An electric lifting clothes drying rack includes a main unit installed on the ceiling or suspended ceiling, and a lifting drying rod assembly. The drying rod assembly is suspended below the main unit via the lifting assembly. The lifting assembly typically includes a steel wire rope and a folding frame. A motor in the housing of the main unit drives the steel wire rope to wind or lower, thereby driving the drying rod assembly to rise and fall. The folding frame folds or unfolds as the drying rod assembly rises and falls, thus ensuring the stability of the drying rod assembly.

[0003] The lifting assembly is connected to the pole seat in the drying rod assembly. For example, the connection structure between the folding frame and the pole seat disclosed in utility model patent CN218708977U includes a connecting rod, a pin, and a pole seat at the lower middle position of the folding frame; the end of the connecting rod has a connecting hole; the pole seat includes a cavity with an open upper end, in which a first fixing member and a second fixing member are fixedly connected; the middle part of the pin passes through the connecting hole of the connecting rod, the first end of the pin is fixed to the first fixing member, and the second end of the pin is fixed to the second fixing member.

Detailed Implementation

[0047] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of the invention.

[0048] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Similarly, terms such as "first" and "second" are only for the purpose of facilitating understanding and have no other directional meaning, and should not be regarded as limitations on this invention.

[0049] like Figure 5 and Figure 6 The diagram shows a preferred embodiment of the quick assembly structure 100 for a clothes drying rack lifting assembly provided by the present invention, which includes a rod base 10, a pair of hook fasteners 20, a folding frame 30, and an elastic pin p.

[0050] like Figures 1 to 3 As shown, the rod base 10 includes a bottom wall 11 and two opposite side walls 12. The space formed between the bottom wall 11 and the two side walls 12 is the lifting assembly assembly space s1. The bottom wall 11 has symmetrical grooves 13 on both sides, and the two side walls 12 have symmetrical platforms 14 on their inner sides. The two platforms 14 have symmetrical protrusions 15 on their upper sides.

[0051] In this embodiment, a plurality of reinforcing ribs 40 are integrally formed on the inner wall of the rod base 10 along its length. First reinforcing ribs 41 are provided on both sides of the bottom wall 11, second reinforcing ribs 42 are provided in the middle of the inner side of each side wall 12, and third reinforcing ribs 43 are provided on the upper inner side of each side wall 12. The two first reinforcing ribs 41 are positioned close to the side wall 12 on the same side, forming a groove 13 between them. The second reinforcing ribs 42 form a platform 14, and the third reinforcing ribs 43 form a raised edge 15.

[0052] The advantage of this design is that the reinforcing rib 40, which is integrally formed during the manufacturing process of the rod seat 10, serves as the structure for assembly and fixation with the lifting component. This not only improves the structural strength of the rod seat 10 itself, but also eliminates the need for additional processing of the installation structure and the production of additional fasteners, achieving two goals at once.

[0053] like Figures 1 to 3 , Figure 7 As shown, the pair of hook fasteners 20 provided in this embodiment have the same structure and dimensions, including a base 21, on which a hook hole k for connecting the end of a wire rope is provided. The upper end of the base 21 has a forward-extending abutment edge 22, and the lower end of the base 21 has a downward-extending fastening claw 23, on which a first pin hole q1 is provided. The base 21 of the hook fastener 20 has insertion ears 24 on both sides, and the two platforms 14 of the rod base 10 are respectively provided with insertion interfaces 16 for inserting the insertion ears 24 of the two hook fasteners 20.

[0054] In this embodiment, the base 21 is transversely U-shaped and includes a back plate 50, a first branch 51 at the upper end of the back plate 50, and a second branch 52 at the lower end of the back plate 50. The first branch 51 extends forward and forms an abutment edge 22 at its front end. The second branch 52 also extends forward and extends downward at its front end to form a snap-fit ​​claw 23. Two insertion ears 24 are disposed on both sides of the first branch 51 and extend downward.

[0055] Preferably, the plug ear 24 includes a main body 24a and an end head 24b, the cross-section of the end head 24b being smaller than that of the main body 24a, and the size of the plug interface 16 matching that of the end head 24b. Further, a clearance opening 17 is provided in the middle of the platform 14, and two plug interfaces 16 are respectively located on both sides of the clearance opening 17.

[0056] like Figure 7 and Figure 8 As shown, the hanging hole k includes a first hole portion k1 and a second hole portion k2. The first hole portion k1 is formed on the back plate 50 of the base 21, and the second hole portion k2 extends upward from the first hole portion k1 to the first branch 51. The second hole portion k2 is narrower than the first hole portion k1.

[0057] like Figures 4 to 6As shown, the bottom of the folding frame 30 is provided with a mounting base 31, and a second through-hole q2 is opened in the middle of the mounting base 31. The elastic pin p includes a first pin body p1 and a second pin body p2, which can elastically extend and retract.

[0058] In this embodiment, the first pin p1 has a telescopic cavity m1, and an elastic element m2 is built into the telescopic cavity m1. The elastic element m2 can be a spring, or it can be an elastic sheet, elastic pad, or other components. The second pin p2 has a protruding telescopic rod m3. The first pin p1 and the second pin p2 are inserted to form an elastic pin p. The telescopic rod m3 extends into the telescopic cavity m1 and abuts against the elastic element m2, so that the first pin p1 and the second pin p2 can elastically extend and retract. Preferably, the two ends of the elastic pin p have chamfers p3.

[0059] The mounting base 31 of the folding frame 30 includes two symmetrically arranged sliders 32, which are respectively located on both sides of the mounting base 31. Each slider 32 has a sliding claw 33 extending forward and backward respectively. The interior of the rod base 10 is provided with a sliding track 17, which is formed by the space enclosed by the bottom wall 11 of the rod base 10, the first reinforcing rib 41 on the bottom wall 11, and the second reinforcing ribs 42 on the two side walls 12. Two track reinforcing bars 18 are protruding along the length of the bottom wall 11, and the two track reinforcing bars 18 are respectively located inside the first reinforcing ribs 41 on both sides.

[0060] The following describes the implementation method and technical effects of the quick assembly structure 100 for the clothes drying rack lifting assembly provided by the present invention, including the following steps:

[0061] Step 1, as follows Figure 1 and Figure 2 As shown, the latching claw 23 of a hook fastener 20 is placed into the groove 13 on one side; in this step, the hook fastener 20 is tilted at a certain angle so that its latching claw 23 is placed into the groove 13 on that side; at this time, the clearance opening 17 on the platform 14 makes way for the hook fastener 20 and at the same time plays a positioning role for assembling the hook fastener 20.

[0062] Step two, as Figure 2 As shown, the two plug ears 24 of the hook fastener 20 are inserted into the two plug interfaces 16 of the platform 14. In this step, the hook fastener 20 gradually returns to its original position so that the lower ends of its two plug ears 24 are aligned with the two plug interfaces 16 and inserted. At this time, its end head 24b plays a certain guiding and positioning role.

[0063] Step 3, as Figure 3As shown, the abutting edge 22 of the hook fastener 20 is snapped into the protruding edge 15 and abuts against the lower surface of the protruding edge 15; in this step, the hook fastener 20 continues to gradually return to its original position until its abutting edge 22 is snapped into the protruding edge 15, at which point the hook fastener 20 returns to its original position.

[0064] At this time, the hook fastener 20 is assembled in place, with its hook claw 23 snapping into the groove 13 and its abutting edge 22 abutting the protruding edge 15, so as to fix and limit the hook fastener 20 in the up and down and front and back; the plug ear 24 is inserted into the plug interface 16, so as to fix and limit the hook fastener 20 in the left and right and front and back.

[0065] Step four, another fastener 20 is assembled on the inner side of the other side wall 12 in the manner of steps one to three; at this time, the two fasteners 20 are symmetrically assembled on the inner sides of the two side walls 12.

[0066] Step 5, as Figure 4 As shown, the elastic pin p is inserted into the second pin hole q2 of the mounting base 31 of the folding frame 30; in this step, the first pin p1 and the second pin p2 are inserted into the second pin hole q2 from the two ports of the second pin hole q2 respectively, and the telescopic rod m3 of the second pin p2 extends into the telescopic cavity m1 of the first pin p1 and abuts against the elastic member m2.

[0067] Step six, as Figure 5 and Figure 6 As shown, the mounting base 31 is slid into the rod base 10 from one end, and the two ends of the elastic pin p enter the first pin holes q1 of the hook fasteners 20 on both sides respectively. In this step, the slider 32 of the mounting base 31 slides into the rod base 10 from one end of the sliding track 17, and the bottom of the slider 33 slides on the track reinforcing strip 18. At this time, the first reinforcing rib 41 on the bottom wall 11 limits the slider 32 to the front and back, and the second reinforcing rib 42 on the two side walls 12 limits the slider 32 to the front and back. The track reinforcing strip 18 provides structural reinforcement and a certain support for the slider 33.

[0068] When the two ends of the elastic pin p contact the latching claws 23 of the hooks 20 on both sides, the elastic element m2 is compressed, and the first pin p1 contracts relative to the second pin p2. During this process, the chamfer p3 at the two ends of the elastic pin p cooperates with the latching claws 2 on both sides, guiding the contraction of the first pin p1 relative to the second pin p2. Continue sliding the mounting base 31 until the two ends of the elastic pin p spring into the first pin holes q1 of the hooks 20 on both sides under the elastic restoring force of the elastic element m2, thereby fixing the mounting base 31 of the folding frame 30 on the bottom wall 11 of the rod base 10.

[0069] The present invention also provides a clothes drying rack (not shown in the figure) equipped with a quick assembly structure 100 for a clothes drying rack lifting component, and further includes a main unit (not shown in the figure), a lifting component 60, and a drying rod assembly (not shown in the figure). The drying rod assembly includes a plurality of drying rods and a pair of rod seats 10, which are respectively disposed on both sides of the drying rod assembly. Correspondingly, the lifting component 60 is disposed on both sides of the main unit. The drying rod assembly is suspended and connected to the main unit below through the lifting component 60, and the main unit controls the lifting and lowering of the drying rod assembly through the lifting component 60.

[0070] Among them, such as Figure 9 As shown, the lifting assembly 60 includes a folding frame 30 and a steel wire rope 61. One end of the folding frame 30 and the steel wire rope 61 is connected to the main unit, and the other end is fixedly connected to the pole base 10 through the quick assembly structure 100 of the clothes drying machine lifting assembly. The lower end of the steel wire rope 61 is fixedly connected to a fastener 20 through the hanging hole k. The mounting base 31 of the folding frame 30 is installed on the bottom wall 11.

[0071] like Figure 7 and Figure 8 As shown, after the hook fastener 20 is assembled into the inner side wall 12 of the pole base 10, the space formed between its back plate 50, the first branch 51, the second branch 52, and the side wall 12 of the pole base 10 is the wire rope end receiving space s2. The lower end of the wire rope 61 has a rope buckle 61a. The size of the first hole k1 of the hook hole k is larger than the rope buckle 61a, and the size of the second hole k2 is smaller than the rope buckle 61a. During connection, the rope buckle 61a enters the wire rope end receiving space s2 from the first hole k1, and the second hole k2 restricts the rope buckle 61a within the wire rope end receiving space s2, thereby fixing the lower end of the wire rope 61 to the hook fastener 20 and to the pole base 10.

[0072] It should be noted that, in order for the assembled lifting assembly 60 to suspend the connecting drying rack assembly in a balanced and stable manner, the mounting base 31 of the hook fastener 20 and the folding frame 30 should be fixed as close as possible to the middle of the rod base 10. Therefore, the insertion interface 16 and the clearance opening 17 are opened in the middle of the platform 14 or the second reinforcing rib 42 so that the hook fastener 20 is assembled in the middle of the rod base 10; the second pin hole q2 is opened in the middle of the mounting base 31 so that the elastic pin p is inserted in the middle of the mounting base 31.

[0073] Furthermore, the relative positions and dimensions of the groove 13, platform 14, and protrusion 15 of the rod seat 10 must, on the one hand, be compatible with the structure and dimensions of the hook fastener 20, and on the other hand, since the rod seat 10 utilizes the reinforcing rib 40, the structural reinforcement requirements of the rod seat 10 must also be considered.

[0074] In this embodiment, the first reinforcing rib 41 is disposed on both sides of the bottom wall 11 to reinforce the bottom structure, and the distance between it and the side wall 12 on the same side matches the thickness of the lower end of the latching claw 23 of the hook fastener 20. The second reinforcing rib 42 is disposed at a position slightly below the middle of the side wall 12 to reinforce the side structure, and the distance between it and the bottom wall 11 matches the height of the latching claw 23 of the hook fastener 20. The third reinforcing rib 43 is disposed near the top edge of the side wall 12 to reinforce the edge structure, and the distance between it and the second reinforcing rib 42 matches the distance between the first branch 51 and the second branch 52 of the hook fastener 20.

[0075] Furthermore, each pole seat 10 corresponds to one wire rope 61, but the pole seat 10 is internally equipped with a pair of hooks 20. When connecting the wire ropes 61 on both sides to the pole seats 10 on both sides, it is only necessary to ensure symmetry on both sides. For example, if the wire rope 61 on the left side is connected to the hook 20 on the outer side of the left pole seat 10, then the wire rope 61 on the right side is connected to the hook 20 on the outer side of the right pole seat 10; similarly, if the wire rope 61 on the left side is connected to the hook 20 on the inner side of the left pole seat 10, then the wire rope 61 on the right side is connected to the hook 20 on the inner side of the right pole seat 10, thus ensuring left-right balance. Using hooks 20 with the same structure and size facilitates standardized mass production.

[0076] Therefore, the quick assembly structure and method for the clothes drying rack lifting assembly provided by this invention eliminate the need for drilling holes in the pole base 10, removing complex assembly components and fasteners such as bolts and screws. The hook fastener 20 and folding frame 30 can be assembled to the pole base 10 by hand without the aid of installation tools. After assembly, there are no exposed parts on the outer wall of the pole base 10, resulting in a smooth and aesthetically pleasing appearance and avoiding the negative impact of drilling and fastening on the structural strength of the pole base 10. Furthermore, with the hook fastener 20 fixedly installed on the inner wall of the pole base 10 and connected to the wire rope 61, the front and rear forces on the pole base 10 are more balanced during use, reducing mechanical wear and increasing service life. The overall balance and stability of the lifting assembly 60 during the lifting process are also better.

[0077] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.
