Description

Technical Field

[0001] This utility model relates to a double-pole drying rack, particularly a retractable drying rack for storage and transportation, or for unfolding and use. Background Technology

[0002] A clothes drying rack is an everyday item used for drying clothes on balconies or indoor spaces. In some rental properties or similar settings, fixed clothes drying racks are not suitable, so folding clothes racks are needed. They can be unfolded when in use and easily folded for storage when not in use.

[0003] However, existing folding clothes racks require a certain degree of stability when unfolded, so they often only fold into a flat shape, making them easy to fit into narrow spaces, but not compact enough. Furthermore, many folding clothes racks have fixed dimensions when unfolded, and cannot be adjusted according to the size of the items being dried or the site conditions, thus limiting their application scenarios. In addition, many folding clothes racks only have a single drying rod, further limiting the drying space.

[0004] Currently, clothes drying racks often need to be transported over long distances or by express delivery after production. Therefore, it is desirable to fold them into a very small size to reduce the size of the outer packaging and facilitate transportation. However, adopting a smaller size design often results in customers having to assemble the product when it reaches them, which increases the difficulty of use for the customer.

[0005] Chinese Patent Publication No. CN221320400U discloses a foldable clothes drying rack, a double-pole clothes drying rack product. When unfolded, it has a large base area for stable placement and provides two poles for drying clothes; when folded, its storage volume is also small, making it convenient for storage and transportation. However, the folding mechanism of this product (see attached instruction manual)... Figure 3 Appendix Figure 4 The large number of rods used makes assembly relatively difficult during production.

[0006] Therefore, it is necessary to design a double-pole clothes hanger that is compact enough when folded for easy storage and transportation; easy to unfold; adjustable in size after unfolding for convenient drying; and has ample drying space; and is easy to assemble during the production process.

[0044] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0045] This utility model provides a double-pole telescopic storage and drying rack, which, when unfolded, is as follows: Figure 1 As shown, the intermediate process states are as follows: Figure 2 As shown, the folded-down storage state is as follows Figure 3 As shown.

[0046] This utility model discloses a double-pole telescopic drying rack, which first includes a base mechanism consisting of four uprights 1 that can be telescopically extended or retracted. The base mechanism is specifically as follows: Figures 4-7 As shown.

[0047] The upright 1 is preferably a hollow metal tube with a smooth outer wall, which can be used as a guide rod. The bottom of the upright 1 is fixed with a foot 2, and two sliding sleeves 3 are fitted on the outer wall of the upright 1.

[0048] The base mechanism, in its unfolded or in-process state, projects onto a horizontal plane as a rectangle, with the upright 1 and the base 2 located at the four corners of the rectangle.

[0049] The bottom surface of the foot 2 is a placement plane 21 for contact with the ground and to provide stable support; a fixing cylinder 22 is provided on one side of the foot 2 for fixed connection with the upright 1; the foot 2 has two hinged bases 23 along the two sides of the rectangle projected horizontally onto the base mechanism, that is, the directions of the two hinged bases 23 are perpendicular to each other, and a base hinge shaft 24 is provided in the hinged base 23; a swing rod 4 is hinged to each of the two hinged bases 23 of the foot 2 through the base hinge shaft 24; the bottom of the swing rod 4 is hinged to the foot 2, and the top of the swing rod 4 is hinged to the sliding sleeve 3.

[0050] The main body of the sliding sleeve 3 is a hollow sleeve with a sleeve 34, which cooperates with the cylindrical outer wall of the upright rod 1 to form a vertical sliding mechanism; on the outside of the sleeve 34, there is a hinged slide 35 and a slide hinge shaft 36; the top of the swing rod 4 is installed in the hinged slide 35 of the sliding sleeve 3 through the slide hinge shaft 36.

[0051] The two ends of the swing arm 4 are respectively provided with mounting hinge holes 43, which are used to hinge with the base hinge shaft 24 and the slide hinge shaft 36 respectively.

[0052] Furthermore, each side of the rectangular base mechanism is provided with two intersecting swing rods 4. Additionally, a stabilizing hinge hole 44 is provided in the middle of each swing rod 4. The stabilizing hinge holes 44 of the two intersecting swing rods 4 are hinged together, making the position of the intersecting swing rods 4 more stable and preventing bending and deformation during extension and retraction.

[0053] When the two diagonally opposite uprights 1 move relative to each other, the sliding sleeve 3 slides on the uprights 1, which in turn causes the swing arm 4 to swing accordingly, realizing the synchronous extension and retraction movement of the four uprights 1 of the base mechanism, thereby realizing the unfolding or folding.

[0054] Furthermore, since there are two sliding sleeves 3 on a single upright post 1, the sliding sleeves 3 cannot overlap in the height direction. The lower sliding sleeve 3 is a narrow sliding sleeve 31, connected to a short swing rod 41, and the upper sliding sleeve 3 is a wide sliding sleeve 32, connected to a long swing rod 42. Therefore, the horizontal projection rectangle of the base mechanism of this utility model after unfolding is rectangular. During the inward retraction process, the long swing rod 42 swings a greater distance, thus allowing the wide sliding sleeve 32 to slide a greater distance. Therefore, its position at the top allows for a greater vertical stroke. Conversely, the short swing rod 41 swings a relatively smaller distance, resulting in a smaller sliding distance for the narrow sliding sleeve 31. Therefore, its position at the bottom effectively avoids motion interference.

[0055] Furthermore, during the unfolding process, the swing distance of the long swing arm 42 is also greater than that of the short swing arm 41. When the wide-direction sliding sleeve 32 moves downward, it will contact the narrow-direction sliding sleeve 31 at a certain moment, thus locking the unfolded position. At this time, the unfolded size of the base mechanism is at its maximum. Further, in this state, a limiting sleeve 33 is installed below the narrow-direction sliding sleeve 31. The limiting sleeve 33 has a locking screw 332 and a sleeve 333. The sleeve 333 of the limiting sleeve 33 is fitted onto the upright 1. At a designated height position on the upright 1, the locking screw 332 is tightened to fix the position of the limiting sleeve 33 on the upright 1. This ensures that when the narrow-direction sliding sleeve 31 finishes its downward movement during unfolding, it abuts against the limiting sleeve 33, stabilizing the unfolded position of the narrow side of the projected rectangle of the base mechanism. At this time, the wide-direction sliding sleeve 32 also abuts against the narrow-direction sliding sleeve 31, stabilizing the unfolded position of the wide side of the projected rectangle of the base mechanism, thus obtaining a stably unfolded base mechanism.

[0056] In a second aspect, the double-pole telescopic storage and drying rack of this utility model includes a lifting rod 16 fitted inside each upright 1, thereby allowing for overall height adjustment. A height adjustment locking mechanism 17 is provided between the upright 1 and the lifting rod 16, typically installed at the top of the upright 1, and the height of the lifting rod 16 after it is raised is locked using a knob or similar method.

[0057] This utility model discloses a double-pole telescopic drying rack. A drying rod 5 is provided at the top of the upright rod 1 / lifting rod 16 to form a drying space. The drying rod 5 is also a telescopic rod, that is, it includes an extension rod 52. A locking mechanism 53 is provided between the extension rod 52 and the drying rack 5 to lock the extension position of the extension rod 52. In particular, when the extension rod 52 is fully extended during use, the position is locked to obtain a longer drying space. When the extension rod 52 is fully retracted during storage, the position is locked to ensure that it will not accidentally extend during storage and affect the storage process.

[0058] This utility model discloses a double-pole telescopic drying rack. For ease of use, a portion of the drying rod 5 is mounted on the top of the upright 1 / lifting rod 16 via a hinged bracket 61, while the other portion of the drying rod 5 is detachably connected to a quick-release bracket 62, which is mounted on the top of another upright 1 / lifting rod 16. In use, the drying rod 5 is rotated around the hinged bracket 61 and lifted, then inserted into the quick-release bracket 62. When storing, the drying rod 5 is removed from the quick-release bracket 62, then rotated around the hinged bracket 61 and lowered, almost parallel to the direction of the upright 1. In particular, the drying rod 5 is rotated into the space between the four uprights 1. Finally, after storage, the two drying rods 5 are wrapped by the four uprights 1, making the stored volume very small.

[0059] The structure of the drying rod 5 connected to the lifting rod 16 via the hinged bracket 61 is as follows: Figure 8As shown; the hinge bracket 61 includes a fixed end 611 and a hinge end 612; the fixed end 611 is sleeved on the top of the lifting rod 16 and fixed at the top, or preferably can rotate along the axis of the upright 1 to adjust the angle; the hinge end 612 has a sleeve, and the drying rod 5 is installed in the sleeve; the fixed end 611 and the hinge end 612 are hinged together by a hinge pin 613. The drying rod 5 can swing up and down relative to the upright 1 / lifting rod 16 through the hinge bracket 61 to adjust the angle; at the same time, the drying rod 5 can rotate relative to the upright 1 through the hinge bracket 61 (it can be a relative rotation between the fixed end 611 and the lifting rod 16, or a relative rotation between the lifting rod 16 and the upright 1). Preferably, the drying rod 5 is slidably connected to the sleeve of the hinge end 612, so that the position of the drying rod 5 on the hinge bracket 61 can be further adjusted, especially when storing, the drying rod 5 can be slid downward to further reduce the height.

[0060] The structure of the quick-release bracket 62 is as follows Figure 9 As shown; the quick-install bracket 62 includes an installation end 622 and a snap-fit ​​end 623; the installation end 622 is sleeved on the top of another lifting rod 16 and fixed relative to the upright 1, or can rotate along the axis of the upright 1 (the installation end 622 rotates relative to the lifting rod 16, or the lifting rod 16 rotates relative to the upright 1); the top of the installation end 622 is provided with a snap-fit ​​end 623, which is provided with a groove that matches the shape of the drying rod 5. In this embodiment, the drying rod 5 is a round rod, so the snap-fit ​​end 623 is provided with an arc-shaped groove; one side of the snap-fit ​​end 623 has an opening 624. The quick-release bracket 62 itself is made of an elastic material, preferably plastic, which gives the opening 624 a certain degree of elasticity. The outer wall of the drying rod 5 presses against the opening 624 from the outside, which can further open the opening 624, so that the drying rod 5 enters the slot of the locking end 623. The opening 624 then automatically resets and forms a wrapping and fixing effect on the drying rod 5. When the drying rod 5 is removed from the locking end 623, the outer wall of the drying rod 5 presses against the opening 624 from the inside, which opens the opening 624, thereby removing it from the slot of the locking end 623. The opening 624 then automatically resets.

[0061] Furthermore, several circumferential reinforcing ribs 625 are provided on the outer wall surface of the snap-fit ​​end 623, which can improve the strength of the snap-fit ​​end 623.

[0062] Preferably, both ends of the drying rod 5 (one end is one end of the drying rod 5 body, and the other end is the extension end of the extension rod 52) are also fitted with protective heads 55 to prevent clothes from being scratched by the ends of the drying rod 5 when they are laid flat on the drying rod 5 for drying.

[0063] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
