Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying racks, in particular to a clothes drying rack with an improved folding connector. Background Art

[0002] A clothes drying rack is a rack used for drying clothes. In order to facilitate storage and transportation, a clothes drying rack often adopts a folding structure. The wing-shaped clothes drying rack connects two symmetrical drying wings and two symmetrically arranged support frames through a folding connection assembly, and then connects the drying wings and the support frames through support members. Under the action of the support members, the drying wings and the support frames are opened and positioned at a set angle. When folding, the supporting effect of the support members is released, so that the drying wings and the support frames rotate relative to each other and close together. The folding connection assembly includes a folding connecting rod and two symmetrically arranged folding connecting members fixed at both ends of the folding connecting rod. The drying wings and the support frames are both rotatably mounted on the folding connecting members. The traditional folding connector is composed of two plates and a connecting plate. The two plates are arranged at intervals and the upper parts of the two plates are connected by the connecting plate. The drying wings and the support frame are arranged between the two plates. Therefore, the connection between the drying wings and the support frame and the folding connector is located on the same plane. When folding, the drying wings and the support frame are prone to interference and collision, resulting in the drying wings and the support frame being unable to completely close together after folding, resulting in a gap. The folded volume is large and the folded structure is loose, which is easy to be damaged during transportation. In order to solve this problem, the existing technology, such as Chinese utility model patent: 2019209440819, an improved butterfly type A floor-standing clothes drying rack comprises a connecting assembly, two symmetrically arranged drying wing racks and two symmetrically arranged supporting legs. The connecting assembly is provided with a middle cross bar and two connecting shells, which are respectively installed at both ends of the middle cross bar. A symmetrical upper mounting hole is respectively provided on the left and right sides of the upper part of the connecting shell, and a symmetrical lower mounting hole is respectively provided on the left and right sides of the lower part of the connecting shell. The upper mounting hole and the lower mounting hole located on the same side of the connecting shell are horizontally staggered; the inner end portions of the two drying wing racks are respectively rotatably installed on the upper mounting holes on the left and right sides of the connecting shell, and the inner end portions of the two supporting legs are respectively rotatably installed on the lower mounting holes on the left and right sides of the connecting shell. This patent solves the problem that the drying wings and the support frames cannot be completely closed together after folding by staggering the upper mounting holes and the lower mounting holes horizontally so that the connection between the drying wings and the folding connecting piece is located on the outside of the connection between the support frame and the folding connecting piece. After the clothes drying rack is folded, the two support frames are located between the two drying wings, thereby solving the problem that the drying wings and the support frames cannot be completely closed together after folding. However, the distance between the rotation axes of the two drying wings is relatively far. After folding, the drying wings and the support frames are closed together in the horizontal direction, and the two support frames are clamped between the two drying wings, so that they still occupy a large horizontal space after folding, and the volume after folding is still large, which is not convenient for storage and transportation. Therefore, it is necessary to improve it. Utility Model Content

[0032] The following are merely preferred embodiments of the present invention and do not limit the scope of protection of the present invention.

[0033] A clothes drying rack with an improved folding connector, such as Figures 1 to 7As shown, it includes a folding connection component 1, two symmetrically arranged drying wing frames 2, two symmetrically arranged foot frames 3 and two symmetrically arranged adjustment frames 5, two folding connections 12 are respectively arranged at the two ends of the folding connection rod 11, the two drying wing frames 2 and the two foot frames 3 are respectively hinged to the folding connection component 1, and the two adjustment frames 5 are respectively arranged between each drying wing frame 2 and each foot frame 3. The folding connection component 1 includes a folding connection rod 11 and two symmetrically arranged folding connections 12, the two folding connections 12 are respectively arranged at the two ends of the folding connection rod 11, the folding connection component 12 is provided with a drying connection groove 121 and a support connection groove 122, the drying connection groove 121 and the support connection groove 122 are staggered along the length direction of the folding connection rod 11, the inner end portions of the two drying wing frames 2 are respectively hinged to the left and right sides of the drying connection groove 121, and the upper ends of the two foot frames 3 are respectively hinged to the left and right sides of the support connection groove 122.

[0034] The distance between the rotation axes of the two drying wing frames 2 of the traditional clothes drying rack is relatively far. After folding, the two legs 3 must be clamped between the two drying wing frames 2, which causes the two drying wing frames 2 and the two legs 3 to be arranged side by side in the transverse direction, respectively, occupying a large transverse space. However, the utility model makes the width of the drying wing frames 2 smaller than the width of the legs 3, or the width of the legs 3 is smaller than the width of the drying wing frames 2 by staggering the drying connection grooves 121 and the support connection grooves 122. When folding, the drying wing frames 2 will not interfere with the legs 3, avoiding bulges, and are flatter after folding; the distance between the rotation axes of the two drying wing frames 2 is shortened, and the two drying wing frames 2 can be close together after folding, thereby reducing the transverse width after folding, thereby reducing the volume after folding, reducing space occupancy, and facilitating transportation and storage.

[0035] Specifically, the folding connector 12 is provided with two drying connection grooves 121, with a rod insertion groove 123 provided between the two drying connection grooves 121. The end of the folding connecting rod 11 is inserted into the rod insertion groove 123, and the inner ends of the two drying wing frames 2 are respectively hinged to the two drying connection grooves 121. When folding, the inner walls of the two drying connection grooves 121 respectively limit the position of the two drying wing frames 2, thereby ensuring that the two drying wing frames 2 can be aligned with the clamping feet of the folding connector 12 after folding.

[0036] Specifically, the two drying connection slots 121 are each provided at the upper portion of the folding connection member 12, and the supporting connection slot 122 is provided at the lower portion of the folding connection member 12. Each drying connection slot 121 is provided with an upper mounting hole 124, and lower mounting holes 125 are symmetrically provided on the left and right sides of the supporting connection slot 122. The two lower mounting holes 125 are respectively located between the two upper mounting holes 124. The inner ends of the two drying wing frames 2 are rotatably mounted to the upper mounting holes 124 in the two drying connection slots 121, and the upper ends of the two legs 3 are respectively hinged to the two lower mounting holes 125. The distance between the two upper mounting holes 124 is greater than the distance between the two lower mounting holes 125, thereby increasing the thickness of the drying wing frames 2 and improving the structural strength. Furthermore, when the two drying wing frames 2 are folded, a certain gap is formed between them to accommodate other components, further improving the compactness of the folded structure.

[0037] Specifically, the inner end of each upper mounting hole 124 and each lower mounting hole 125 is provided with a nut retaining slot 126. A nut is embedded in each nut retaining slot 126. Bolts are threaded through each upper mounting hole 124 and each lower mounting hole 125. Each bolt is threadedly connected to a corresponding nut, and the drying wing racks 2 and the foot racks 3 are hingedly connected to the corresponding bolts. The foldable connector 12 is integrally injection-molded from plastic. The nuts are secured by the nut retaining slots 126, and the foldable connector 12 is then connected to each drying wing rack 2 and foot rack 3 by bolts. This simple structure, low cost, and easy production are achieved.

[0038] Specifically, an isolation plate 127 is provided between the drying connection slot 121 and the supporting connection slot 122. The drying connection slot 121 is located inside the isolation plate 127, while the supporting connection slot 122 is located outside the isolation plate 127. The drying connection slot 121 is located inside the supporting connection slot 122, making the width of the drying wing rack 2 smaller than the width of the foot rack 3. This ensures that the weight of the drying wing rack 2 and the clothes hung on it are both placed between the two foot racks 3, thereby improving the structural strength of the clothes drying rack and increasing its load-bearing capacity.

[0039] Specifically, each drying wing frame 2 includes two drying connecting rods 21 and multiple drying hanging rods 22. The inner ends of the two drying connecting rods 21 are respectively hinged to the drying connecting slots 121 of the two folding connectors 12. Each drying hanging rod 22 is connected between the two drying connecting rods 21. The drying hanging rods 22 are spaced apart in the transverse direction. The drying connecting rods 21 and the drying hanging rods 22 are both universal rods, which facilitates production. When in use, clothes are hung on each drying hanging rod 22, resulting in a simple structure and low cost.

[0040] Specifically, the drying wing rack 2 is further provided with a mother-and-baby rod 23 and a plurality of mother-and-baby clips 24. The mother-and-baby rod 23 is fixedly connected between the outer ends of the two drying connecting rods 21, and each mother-and-baby clip 24 is movably mounted on the lower portion of the mother-and-baby rod 23. The mother-and-baby rod 23 not only increases the structural strength of the drying wing rack 2 but also increases the drying capacity. The mother-and-baby clips 24 are used to hold small items of clothing such as socks, making it more convenient to use.

[0041] Specifically, each leg 3 includes two support rods 31 and at least two support links 32. The upper ends of the two support rods 31 are respectively hinged to the support connection slots 122 of the two folding connectors 12, and each support link 32 is fixedly connected between the two support rods 31. The support rods 31 and support links 32 are universal rods, facilitating production. When the clothes drying rack is unfolded, the two legs 3 rotate apart to form a herringbone shape. When folded, they rotate relative to each other and close together. The drying wings 2 can pass between the support rods 31, thereby avoiding collision and interference with the legs 3.

[0042] Specifically, each foot stand 3 is further provided with multiple shoe-drying boards 33. At least two supporting links 32 are spaced apart below the supporting foot rods 31, and each shoe-drying board 33 is snap-fitted to each of the two supporting links 32. The lower end of each supporting foot rod 31 is provided with a supporting foot cover 34, which is equipped with a pulley assembly. The supporting links 32 are positioned below the supporting foot rods 31 to avoid the drying wing racks 2 and are used to secure the shoe-drying boards 33. When drying shoes, shoes can be directly placed on the shoe-drying boards 33, increasing the amount of drying, improving the drying efficiency, and making it more convenient to use.

[0043] Specifically, each tripod 3 is also provided with a limited drying rack 4, the outer ends of the two limited drying racks 4 are respectively hinged to the middle parts of the two tripods 3, and the inner ends of the two limited drying racks 4 are respectively provided with limited folding parts 41, and the upper parts of the opposite sides of the limited folding parts 41 of the two limited drying racks 4 are abutted and matched, and the lower parts are rotatably connected; the adjustment rack 5 includes an adjusting strut 51 and two adjusting connecting rods 52, the lower ends of the two adjusting connecting rods 52 are respectively hinged to the middle parts of the tripod 3, the two ends of the adjusting strut 51 are respectively connected to the upper parts of the two adjusting connecting rods 52, and the two ends of the adjusting strut 51 protrude from the outer side surfaces of the two adjusting connecting rods 52, and the two ends of the adjusting strut 51 are respectively abutted and matched with the two drying connecting rods 21 of the same drying wing rack 2, and the upper ends of the two adjusting connecting rods 52 are respectively abutted and matched with any one of the drying hanging rods 22 of the same drying wing rack 2. When unfolding the clothes drying rack, first rotate the two legs 3 to open, then rotate the drying wing rack 2 upward, and at the same time rotate the adjustment rack 5 upward, and make the adjustment connecting rod 52 of the adjustment rack 5 press against any one of the drying hanging rods 22, and adjust the support rod 51 to press against the adjustment connecting rod 52, so as to lift and fix the drying wing rack 2; then rotate the two limiting drying racks 4 to make the two limiting drying racks 4 horizontal and located in the same plane, so as to fix the two legs 3, avoid the two legs 3 from folding accidentally, and improve the structural strength and firmness.
