[0058] 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.

[0059] 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 may not be further defined or explained in subsequent drawings.

[0060] like Figure 1 The figure shows a schematic diagram of the folding rack installation structure in the prior art. In the prior art, a roller assembly is located inside the connecting rod at the upper end of the folding rack, and the roller assembly includes a coaxial first roller and a second roller; a horizontal slot is provided on the vertical plate of the housing, the first roller is located inside the vertical plate, and the second roller is located outside the vertical plate, so that the roller moves along the slot when the folding rack is raised or lowered. However, this technical means has technical problems, including that the installation process at the upper end of the folding rack is redundant and complicated, and the cooperation between the roller assembly and the slot is prone to displacement when subjected to the pulling force of the clothes drying rack assembly, which will cause uneven force on the roller in the long run, and the inner wall of the roller and the wall where the slot is located will rub and squeeze, which is easy to be damaged and also easy to make noise.

[0061] In order to solve this technical problem, the present technical solution provides a mounting structure 100 of a folding rack of a clothes drying machine, such as Figure 2 and Figure 3 As shown, the mounting structure 100 comprises a folding frame 10, a rod base 20 and an inverted L-shaped side plate 30. The folding frame 10 is composed of a plurality of connecting rods 11 axially connected to each other, and can be unfolded, folded and retracted in the longitudinal direction.

[0062] The rod seat 20 is provided with a first track h1, and the lower end of the folding frame 10 is connected to the first track h1. The inverted L-shaped side plate 30 includes a vertical plate 31 and a horizontal plate 32 that close the inner cavity of the main unit. The outer side of the horizontal plate 32 is provided with at least one notch 33; the notch 33 is used for expansion screws or other fasteners to pass through to fix the main unit components to the ceiling. Preferably, a plurality of notches 33 are opened on the outer side of the horizontal plate 32, and the notches 33 are symmetrical on the horizontal plate 32; thereby ensuring stable and balanced installation.

[0063] First, the folding frame 10 is composed of a plurality of connecting rods 11 connected to each other, so that the folding frame 10 of the clothes drying machine can be unfolded and folded in the longitudinal direction, thereby achieving more flexible use. This design not only saves space, but also allows the drying height to be easily adjusted as needed to meet the drying needs of different clothes.

[0064] Secondly, the design of the rod base 20 provides a stable support base, and the lower end of the folding rack 10 is connected and fixed by the first rail h1, ensuring the stability and balance of the entire structure. In this way, it is not easy for the clothes drying rack to tilt or the folding rack to be unstable when drying clothes, thereby improving the drying efficiency and safety.

[0065] The introduction of the inverted L-shaped side plate 30 increases the firmness and reliability of the structure. The vertical plate 31 that closes the inner cavity of the main machine effectively protects the internal components of the clothes drying machine, reduces the possibility of being affected by the external environment, and prolongs the service life of the clothes drying machine.

[0066] Furthermore, and more importantly, Figures 4 to 7 As shown, an upper guide rail 40 is fixedly installed at the bottom of the transverse plate 32, and a second rail h2 is provided on the upper guide rail 40, and the second rail h2 and the first rail h1 are in the same vertical plane to ensure that the longitudinally extending folding frame 10 is always lifted and lowered along the same straight line to ensure stability and avoid power loss, thereby ensuring the reliability and durability of the clothes drying machine.

[0067] A fixed shaft 12 is disposed in the middle of the upper end of the folding frame 10 , and an upper sliding block 50 is disposed on both sides of the upper end of the folding frame 10 .

[0068] When the folding frame 10 is unfolded and folded, the upper slider 50 can slide in the second track h2; the two upper sliders 50 can move toward and away from each other synchronously relative to the fixed shaft 12.

[0069] In this technical means, the folding frame 10 is connected to the inverted L-shaped side plate 30 through an upper guide rail 40, and the connecting rod 11 required by the folding frame 10 itself is coordinated to operate through the second track h2. The same technical feature realizes a two-way technical function, and the installation structure of the upper guide rail 40 itself is simpler and the installation is faster. There will be no friction or abnormal noise between the parts.

[0070] In addition, the slider 50 on the folding frame 10 moves synchronously along the second track h2 to ensure balanced movement of the folding frame 10 when unfolding and folding, minimizing power loss, which makes the clothes drying machine more labor-saving and efficient during use.

[0071] Furthermore, the folding rack 10 always moves along the same straight line during the lifting process, thereby avoiding the resistance caused by friction or irregular movement of the clothes drying rack and ensuring the smooth movement of the folding rack 10 .

[0072] More specifically, the upper guide rail 40 includes an upper bottom wall 41, a first side wall 42 and a second side wall 43 are provided at the lower side of the upper bottom wall 41, a first folded edge b1 is provided at the lower portion of the first side wall 42, and a second folded edge b2 is provided at the lower portion of the second side wall 43 to form a second track h2. This structure can not only effectively support the movement of the folding frame, but also ensure that the folding frame 10 moves stably along the predetermined track during the lifting process, thereby improving the reliability and durability of the overall structure.

[0073] The upper bottom wall 41 extends outward to form a first outer wall a1, and the first outer wall a1 is fixed to the transverse plate 32 by multiple screws, ensuring the firm connection and stability of the upper guide rail 40. The upper bottom wall 41 extends inward to form a second outer wall a2, and the vertical plate 31 is integrally stamped to form multiple pressing pieces c, and the pressing pieces c press against the lower end surface of the second outer wall a2. These pressing pieces c can fully press against the lower end surface of the second outer wall a2, providing a supporting means symmetrical to the first outer wall a1, ensuring the balance and stability of the upper guide rail 40. This prevents the folding frame 10 from shaking and deflecting during movement.

[0074] The upper slider 50 is made of rubber material, and the two first connecting rods 11 at the head end of the folding frame 10 are respectively connected to the corresponding upper slider 50. The upper slider 50 is made of rubber material, which has good friction performance and wear resistance, can effectively reduce the friction between the folding frame 10 and the upper guide rail 40, and provide smoother movement. At the same time, the rubber material can also effectively reduce noise and vibration, and improve the comfort of using the clothes drying machine.

[0075] More preferably, the two first connecting rods 11 are axially connected with the support rods 13, and the outer ends of the two support rods 13 are connected by the fixed shaft 12, and the fixed shaft 12 is fixedly connected to the side wall of the upper guide rail 40. A strong connection frame is formed by the two first connecting rods 11 being axially connected with the support rods 13 and the outer ends of the support rods 13 being connected by the fixed shaft 12. The fixed shaft 12 is fixedly connected to the side wall of the upper guide rail 40, which further ensures the stability and safety of the folding frame 10.

[0076] In addition, if Figure 8 and Fig. 9 As shown, the pressing member c includes a connecting arm c1 inclined outwardly and a supporting arm c2 whose outer end extends straight toward the second outer wall a2. The cross section of the supporting arm c2 completely falls into the inner side area of ​​the second outer wall a2 for sufficient pressing.

[0077] The outward-inclined connecting arm c1 enables the pressing member c to exert an outward force externally. The supporting arm c2 further strengthens the pressing force of the pressing member c on the second outer wall a2. The cross section of the supporting arm c2 completely falls into the inner side area of ​​the second outer wall a2, ensuring close contact between the pressing member c and the second outer wall a2. This technical means can not only fully press but also effectively disperse the pressure.

[0078] Preferably, the first and second outer walls are on the same plane with the upper bottom wall 41, and the upper guide rail 40 is closer to the second outer wall a2, which can enhance the stability of the entire structure. By arranging key components on the same plane, the distortion and deformation of the structure are reduced, and the overall stability of the folding frame is improved.

[0079] In addition, preferably, the slider of the utility model is made of a high-performance polymer, the slider has a low friction coefficient and good wear resistance, can effectively reduce the friction loss during sliding, and has a long service life.

[0080] In addition, the notch 33 has a considerable length so that its inner end can extend to a position closer to the inside of the transverse plate 32, so that the fixing point can achieve a more adequate connection and fixing effect. The outer end of the notch 33 is at the outer edge of the transverse plate 32, and the outer end of the notch is in a bell-shaped shape. The bell-shaped design makes it easier for the fastener to be inserted into the notch 33, and can also prevent the fastener from accidentally falling off due to external forces. It also has the effect of simplifying installation. In general, the sufficient length and bell-shaped design of the notch 33 can effectively reduce the possibility of structural defects. By ensuring that the fastener is fully inserted into the notch 33 and firmly connected, the risk of structural loosening or damage caused by unstable connection can be reduced, thereby improving the reliability and durability of the overall structure.

[0081] At the same time, an inwardly recessed arcuate recess is provided on the first outer wall a1 , and each arcuate recess corresponds to a notch 33 . The design of the arcuate recess can effectively avoid interference of the wall surface with the installation of fasteners at the notch 33 .

[0082] 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.
