[0053] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0054] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0055] like Figure 1 As shown, the clothes drying machine 200 in this embodiment includes a main unit 201 and a clothes drying assembly 202, and the clothes drying assembly 202 and the main unit 201 are connected by a liftable assembly. This technical solution aims to elaborate the upper and lower positioning structure 100 of the fixed clothes drying rod and the movable clothes drying rod, as follows:

[0056] like Figures 2 to 5 As shown, the upper and lower positioning structure 100 of the fixed airing rod and the movable airing rod, the movable airing rod 30 is connected to the fixed airing rod 101 through a rotating arm 20. The design of the rotating arm 20 allows the movable airing rod 30 to be rotated and positioned at multiple angles on the fixed airing rod 101, so that the airing rod can be adjusted according to the needs of the user and the space conditions, so as to adapt to clothes or quilts of different sizes and shapes.

[0057] The design of the fixed clothes-drying rod 101 adopts a rectangular structure, which is not only simple but also very practical. It is composed of two parallel first cross bars 11 and two second cross bars 12 perpendicular to the first cross bars. Such a layout provides a stable foundation for supporting the clothes-drying rod 14 and the movable quilt-drying rod 30. The four corner seats 13 are respectively located at the connection between the first cross bar 11 and the second cross bar 12. They not only play a role in structural reinforcement, but also help to disperse and carry the weight generated when drying clothes.

[0058] The extending direction of the first crossbar 11 is perpendicular to the extending direction of the second crossbar 12, the two first crossbars 11 are parallel to each other, and the two second crossbars 12 are parallel to each other. The parallel and vertical crossbar layout maximizes the clothes drying space, allowing the user to dry more clothes or bedding in a limited area.

[0059] In addition, the vertical connection between the first crossbar 11 and the second crossbar 12, combined with the use of the corner seat 13, enhances the rigidity and load-bearing capacity of the entire structure.

[0060] A clothes-drying rod 14 is connected to the lower side of the first crossbar 11, and a plurality of hanging holes 15 are distributed on the clothes-drying rod 14. The clothes-drying rod 14 is connected to the lower side of the first crossbar 11, and this technical means fully utilizes the space of the clothes-drying machine. The design of the hanging holes 15 is convenient for users to hang and take out clothes.

[0061] More specifically, the corner seat 13 includes a first interface c1 and a second interface c2. During actual installation, the first interface c1 is for the end of the first crossbar 11 to be inserted, and the second interface c2 is for the end of the second crossbar 12 to be inserted. The four corner seats 13 form the corners of the rectangular structure, providing structural stability. The provision of the first interface c1 and the second interface c2 ensures that the first crossbar 11 and the second crossbar 12 can be accurately connected to the corner seat 13, reducing errors during installation. The design of the first interface c1 and the second interface c2 allows the first crossbar 11 and the second crossbar 12 to fit tightly, optimizing space utilization and making the clothes drying machine more compact.

[0062] Furthermore, if Figure 6 As shown, the first interface c1 includes a top wall c11, a bottom wall and two side walls to form a three-dimensional space for accurately fixing the end of the rod. In addition, a recessed groove p is provided on the upper surface of the top wall c11 in the same extending direction as the first crossbar 11.

[0063] When the movable drying rod 30 needs to be stored, the movable drying rod 30 is moved to the recessed groove p by rotating the arm 20, and the bottom surface of the end of the movable drying rod 30 falls into the recessed groove p. The bottom surface of the end is tightly combined with the groove, which reduces the risk of falling off due to wind or shaking and improves the stability of the clothes drying machine.

[0064] Since the movable quilt-drying rod 30 can be directly stored in the corner seat 13 of the fixed quilt-drying rod 101, there is no need to set up an additional storage structure, which simplifies the design and reduces the cost. In addition, since there is no complicated quilt-drying rod locking structure, the storage process is faster and more flexible, and it is sufficient to ensure considerable stability after storage. The user can operate it freely without special tools or skills. After storage, the movable quilt-drying rod 30 and the fixed quilt-drying rod 101 form a whole, and the appearance is neat and tidy, and does not affect the beauty of the home environment.

[0065] Preferably, at least one of the bottom surface of the end of the movable quilt drying rod 30 and / or the recessed groove p is provided with a rough surface that can increase the friction between the contact surfaces of the two.

[0066] The rough surface is an anti-skid sticker attached to the bottom surface of the end of the movable quilt drying rod and / or in the recessed groove; the anti-skid sticker and rough texture design are easy to check and replace. If worn or damaged, the user can quickly perform maintenance to maintain the optimal performance of the clothes drying machine.

[0067] Alternatively, the rough surface is a rough pattern provided on the bottom surface of the end of the movable quilt drying rod and / or in the recessed groove. Figures 7 to 12 As shown, the coarse grain design has a specific texture or pattern, which can be selected by those skilled in the art as needed.

[0068] The rough surface significantly increases the friction between the bottom surface of the end of the movable quilt drying rod 30 and the recessed groove p, which helps to maintain the stable position of the quilt drying rod and prevent it from sliding or falling off when the clothes drying machine moves or is subjected to external force.

[0069] In addition, the rough surface can reduce the direct friction between metals when the quilt drying rod contacts the slot, thereby reducing noise and providing a quieter user experience.

[0070] More preferably, a texture interlocking structure is provided between the bottom surface of the end of the movable quilt drying rod 30 and the groove surface of the concave groove position p. The texture interlocking structure includes a first texture road surface provided on the bottom surface of the end of the movable quilt drying rod 30 and a second friction road surface distributed on the groove surface. After the bottom surface of the end of the movable quilt drying rod 30 and the groove surface are attached, the textures on the first and second friction road surfaces interlock with each other to enhance stability.

[0071] The mutual engagement of the patterns provides a physical locking mechanism, which can prevent the movable quilt drying rod 30 from accidentally falling out even under strong vibration or wind force.

[0072] Preferably, the grain interlocking structure can more evenly distribute the pressure between the quilt drying rod and the slot, thereby improving the load-bearing capacity of the entire structure.

[0073] More preferably, if Figure 6 As shown, the two sides of the concave groove p are raised upward to form arc-shaped limiting inclined surfaces p1. When the movable quilt drying rod 30 is placed in the concave groove p, the two sides of its bottom wall are limited by the corresponding arc-shaped limiting inclined surfaces p1 to further ensure the stability of the upper and lower positioning structure.

[0074] The arc-shaped limiting slope p1 provides additional lateral support when the movable quilt-drying rod 30 is placed in the recessed groove p, thereby increasing the stability of the structure and preventing the quilt-drying rod from shifting or tilting. During the placement of the movable quilt-drying rod 30, the arc-shaped limiting slope p1 can absorb part of the impact force, reduce direct impact, and protect the structural integrity of the clothes drying machine. In addition, the design of the arc-shaped limiting slope p1 makes the insertion and removal of the movable quilt-drying rod 30 smoother, thereby improving the user's convenience in operation.

[0075] Preferably, a clothes-drying rod 14 is connected to the lower side of the second crossbar 12, and a plurality of hanging holes 15 are distributed on the clothes-drying rod 14 to increase the drying area, and the clothes-drying rod 14 below the first and second crossbars 12, similarly, surround a rectangular frame to be unified with the frame structure of the fixed clothes-drying rack.

[0076] The above technical solution is developed around the recessed groove p on the top wall c11 of the corner seat 13, and the friction lines are arranged on the groove surface of the recessed groove p. In another case, the friction lines and rough surface are directly arranged on the upper surface of the first interface c1 of the corner seat 13 without limiting the recessed groove p. The rest of the technical solution is consistent with the above, and the specific differences are as follows:

[0077] At least one of the bottom surface of the end of the movable quilt drying rod 30 and / or the upper surface of the top wall c11 of the first interface c1 is provided with a rough surface that can increase the friction between the contact surfaces of the two.

[0078] The rough surface is a non-slip sticker attached to the bottom surface of the end of the movable quilt drying rod 30 and / or the upper surface of the top wall c11 of the first interface c1; or the rough surface is a coarse-grained design set on the bottom surface of the end of the movable quilt drying rod 30 and / or the upper surface of the top wall c11 of the first interface.

[0079] A texture interlocking structure is provided between the bottom surface of the end of the movable quilt drying rod 30 and the upper surface of the top wall c11 of the first interface c1.

[0080] The grain interlocking structure includes a first grain road surface provided on the bottom surface of the end of the movable quilt drying rod 30 and a second grain road surface distributed on the upper surface of the top wall c11; after the bottom surface of the end of the movable quilt drying rod 30 and the upper surface of the top wall c11 are attached, the grains on the first and second grain roads interlock with each other to enhance stability. The design of the grain interlocking structure, whether in the recessed groove position p or directly on the top wall c11, can provide a physical locking mechanism to enhance the stability of the movable quilt drying rod 30.

[0081] In addition, the above technical means does not set the recessed slot p, which reduces the processing requirements for the corner seat 13 in manufacturing, thereby reducing production costs. The solution without setting the recessed slot p is visually simpler because the surface of the top wall c11 is smoother. Directly laying friction lines or rough surfaces on the top wall c11 can more easily adapt to different installation angles and directions because they are not limited by the shape of the recessed slot p.

[0082] The solution without the recessed groove p provides greater flexibility, because the friction pattern or rough surface on the top wall c11 can be designed to adapt to the end bottom surfaces of different shapes and sizes.

[0083] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, which are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0084] The above is an introduction to the upper and lower positioning structure of the fixed clothes-drying rod and the movable clothes-drying rod provided by the utility model.
