Description

Technical Field

[0001] This utility model relates to the field of drying rack technology, and in particular to a drying rack with a stable structure and easy installation. Background Technology

[0002] Folding drying racks are practical household items that are easy to store and save space, making them especially suitable for small apartments, balconies with limited space, or situations where temporary drying is required.

[0003] Existing clothes drying racks typically consist of legs and support rods for hanging clothes and other items. The support rods are mounted on the legs and supported on the ground. The support rods are divided into two parts that can be folded and unfolded for easy daily use and storage. For example, Chinese utility model patent CN211547006U, entitled "Portable Clothes Drying Rack," includes a crossbar and a pair of legs supporting the crossbar. The crossbar includes a first support rod and a second support rod, which are hinged to the legs. The first and second support rods are connected by a folding member, which includes a first rotating base and a second rotating base that are movably connected. This movable connection can be a hinge or a pivot. When storage is needed, the two legs are simply folded together. Since the legs lose their supporting function, the folding member rotates, bringing the first and second support rods together, making the entire clothes drying rack on the same plane, reducing its footprint and facilitating storage.

[0004] However, the existing technology still has the following drawbacks:

[0005] 1. In existing clothes drying racks, the two support rods used for hanging clothes are connected to each other by a folding component. However, the first and second rotating bases of the folding component are only connected by a hinge or pivot point. As a result, during daily use, the stress points of the two support rods are concentrated on this one hinge or pivot point, which can easily damage the folding component and increase replacement costs. Moreover, the stability and structural strength of the two support rods are not high enough, and disassembly and assembly are not convenient.

[0006] 2. Existing drying racks can usually only hang clothes and other items on the support rods. Therefore, the drying position, space and area of ​​the drying rack are relatively limited, which cannot meet the users' larger drying needs, nor can it meet the users' diverse and personalized drying needs.

[0007] 3. The existing drying racks have a one-piece molded U-shaped leg structure, which cannot be further disassembled and reassembled, and will still take up a lot of space when folded for storage. Utility Model Content

[0008] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a drying rack with a stable structure and easy installation.

[0009] The purpose of this utility model is achieved by the following technical solution: a drying rack with a stable structure and easy installation, including a first leg, a second leg, a first shelf, a second shelf and a folding assembly, wherein the upper ends of the first leg and the second leg are hinged together, the lower ends of the first leg and the second leg are unfolded and supported on the ground, and the first shelf and the second shelf are correspondingly hinged to the first leg and the second leg.

[0010] The folding assembly has a first tube and a second tube that are hinged together. The first tube has a first sleeve hole and a limiting tube groove. The first tube is sleeved on the first shelf through the first sleeve hole. The second tube has a second sleeve hole and is sleeved on the second shelf through the second sleeve hole.

[0011] When the first and second shelves unfold synchronously with the first and second legs, the second tube unfolds downwards with the hinge point with the first tube as the fulcrum and is embedded in the limiting tube groove; when the first and second shelves fold synchronously with the first and second legs, the second tube flips upwards with the hinge point with the first tube as the fulcrum and disengages from the limiting tube groove.

[0012] Furthermore, both the first and second pipe fittings have integrally formed hinged portions on their pipe walls, and are hinged together at the hinged portions by hinge members.

[0013] Furthermore, the inner diameter of the limiting groove is larger than the outer diameter of the second sleeve hole, and the groove opening of the limiting groove is opened on the same side of the first pipe fitting where the hinge portion is located.

[0014] Furthermore, an arc-shaped reinforcing part is provided on the groove opening of the limiting tube groove and at one end near the hinge.

[0015] Furthermore, the upper ends of the first leg and the second leg are provided with drying horizontal tubes, and the first leg and the second leg are rotated and unfolded or folded around the drying horizontal tubes.

[0016] Furthermore, the drying horizontal tube is provided with several sliding hanging arms, each of which is provided with a sliding sleeve and an extension arm with a hanging hole. The sliding hanging arm is movably sleeved on the drying horizontal tube through the sliding sleeve and can slide back and forth along the axial direction of the drying horizontal tube.

[0017] Furthermore, the first leg is provided with a first frame tube and a first foot tube, and the second leg is provided with a second frame tube and a second foot tube. The upper end of the first frame tube is hinged to the upper end of the second frame tube, the lower end of the first frame tube is detachably sleeved with the first foot tube, and the lower end of the second frame tube is detachably sleeved with the second foot tube.

[0018] Furthermore, the lower ends of the first frame tube and the second frame tube are provided with insertion ends with spring fasteners, and the upper ends of the first leg tube and the second leg tube are provided with buckle holes. When the first frame tube and the second frame tube are inserted into the first leg tube and the second leg tube respectively, they are locked by the spring fasteners snapping into the buckle holes.

[0019] Furthermore, it also includes a folding seat, which is composed of a first folding block and a second folding block that are hinged together and spliced ​​together, with the two folding blocks respectively fitted onto the upper ends of the two frame tubes.

[0020] Furthermore, the left and right sides of the first shelf are hinged to the first frame tube, the left and right sides of the second shelf are hinged to the second frame tube, the first shelf and the second shelf are on the same horizontal plane when flipped and unfolded, and a number of equidistant drying rods are provided on the first shelf and the second shelf.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] (1) In this embodiment, the first and second shelves are hinged together by a folding assembly. The second and first tubes of the folding seat are unfolded in reverse with the hinge point as the fulcrum, and the second tube is embedded in the limiting groove of the first tube. Compared with the previous implementation where the force points of the two support rods are concentrated on a single hinge point, this embodiment can distribute the force points at the snap-fit ​​between the second tube and the limiting groove, disperse the force of a single hinge point, increase the force area, improve the structural strength, avoid excessive force concentration and damage to the folding assembly, reduce replacement and maintenance costs, and improve the stability of the unfolded state between the first and second tubes. It also improves the stability of the unfolded support structure between the first and second shelves and between the first and second legs, making the overall structure more robust and the disassembly and assembly of the drying rack more convenient.

[0023] (2) By setting a drying horizontal tube at the upper end of the support leg and setting several sliding hanging arms on the drying horizontal tube, the position of the sliding hanging arm can be adjusted so that its extension arm extends outward from the angle between the first support leg and the second support leg, thereby adapting to hanging clothes of different sizes, improving space utilization, and by setting hanging holes on the extension arm for hanging clothes hangers or hooks, the hanging hole design realizes three-dimensional drying and meets personalized needs.

[0024] (3) By dividing the first leg into a first frame tube and a first foot tube, and the second leg into a second frame tube and a second foot tube, the split structure of the legs reduces the volume after folding, making it easier to store and reducing transportation and storage costs; and by using the plug-in design of the frame tube and the foot tube, transportation and storage costs are further reduced, and the connection is secured by the spring buckle to prevent accidental loosening during use, and the disassembly and assembly steps are simplified to improve the user's ease of operation.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] like Figure 1-7 As shown, a sturdy and easy-to-install drying rack is a practical household item that is easy to store and saves space, especially suitable for small apartments, balconies with limited space, or situations requiring temporary drying. This sturdy and easy-to-install drying rack consists of a first leg 10, a second leg 11, a first shelf 20, a second shelf 21, and a folding assembly 30. The first leg 10 and the second leg 11 are independent frame structures. The upper ends of the first leg 10 and the second leg 11 are hinged together at hinge points. The lower ends of the first leg 10 and the second leg 11 have anti-slip feet and can be unfolded to support the ground, so that the first leg 10 and the second leg 11 are connected in an approximately inverted V-shape, resulting in a stable structure with better load-bearing capacity.

[0041] Both the first shelf 20 and the second shelf 21 are designed with a U-shaped frame structure. During installation, the left and right sides of the first shelf 20 are hinged to the inner side of the frame structure of the first support leg 10, and the left and right sides of the second shelf 21 are hinged to the inner side of the frame structure of the second support leg 11. Rubber pads can be placed between the hinges of the shelves and the support legs to reduce wear. This allows the first shelf 20 and the second shelf 21 to swing freely up and down on the first support leg 10 and the second support leg 11, respectively, and ensures that the first shelf 20 and the second shelf 21 are on the same horizontal plane when unfolded, facilitating clothing drying. Furthermore, several equidistant drying rods 201 are welded to the first shelf 20 and the second shelf 21 along their horizontal unfolding direction, with a rod spacing of 15-20cm. The equidistant design of the drying rods 201 prevents clothing from piling up and optimizes ventilation. Multiple layers of drying rods 201 can also be installed along the height of the support legs to provide a large flat drying area, increasing drying capacity.

[0042] The folding assembly 30 has a first tube 301 and a second tube 302. One end of the first tube 301 has a first sleeve hole 3011, and the other end of the second tube 302 has a limiting groove 3012. The first sleeve hole 3011 is fitted onto one end of the first shelf 20, and one end of the second tube 302 has a second sleeve hole 3021, which is fitted onto one end of the second shelf 21. Moreover, the first tube 301 and the second tube 302 are hinged together, so that the adjacent ends of the first shelf 20 and the second shelf 21 are hinged together by the folding assembly 30. When unfolded, the second tube 302 can be inserted into the limiting groove 3012, and when folded, it can be disengaged from the limiting groove 3012.

[0043] The specific operating procedure is as follows:

[0044] When the drying rack is unfolded, the lower ends of the first leg 10 and the second leg 11 unfold in opposite directions to a certain distance, presenting an inverted V-shaped support structure; during the unfolding process, the first shelf 20 and the second shelf 21 unfold synchronously with the first leg 10 and the second leg 11 until the first shelf 20 and the second shelf 21 flip to the same horizontal plane; moreover, the second pipe 302 and the first pipe 301 unfold in opposite directions with the hinge point as the fulcrum, and the second pipe 302 is embedded in the limiting pipe groove 3012 of the first pipe 301. Therefore, compared with the previous implementation method that concentrates the stress points of the two support rods on a single hinge point, the embodiment of this application can distribute the stress points at the snap-fit ​​joint between the second tube 302 and the limiting tube groove 3012, disperse the stress on a single hinge point, increase the stress area, improve structural strength, avoid excessive stress concentration and damage to the folding assembly 30, and improve the stability of the unfolded state between the first tube 301 and the second tube 302; it also improves the stability of the unfolded support structure between the first shelf 20 and the second shelf 21, and between the first leg 10 and the second leg 11, reduces replacement and maintenance costs, makes the overall structure more robust, and makes the disassembly and assembly of the drying rack more convenient.

[0045] When folding the drying rack, the lower ends of the first leg 10 and the second leg 11 face each other and come together. During the folding process, the first shelf 20 and the second shelf 21 fold synchronously with the first leg 10 and the second leg 11 until the first shelf 20 and the second shelf 21 are folded onto the legs. Moreover, the second tube 302 and the first tube 301 fold towards each other with their hinge points as fulcrums, and the second tube 302 disengages from the limiting groove 3012 of the first tube 301, so that the drying rack is folded up as a whole. The entire folding process eliminates the cumbersome operation of splicing and disassembling the legs, shelves, and folding components 30, saving time and effort.

[0046] The first pipe fitting 301 and the second pipe fitting 302 each have an integrally formed hinge portion 3013 on their pipe walls, meaning the hinge portion 3013 is seamlessly connected to the pipe fitting body, avoiding welding or bolt fixing. The hinge portion 3013 is designed as a cylinder, or it can be designed as a U-shaped lug structure. The hinge portion 3013 has a connecting hole and is hinged by a pin or rivet, thus allowing the first pipe fitting 301 and the second pipe fitting 302 to be hinged together, enabling them to be flipped open and folded for storage. By integrally forming the hinge portion 3013 on the pipe fittings, the number of parts can be reduced, the risk of wear can be lowered, durability can be improved, and the overall bending resistance can be enhanced.

[0047] The inner diameter of the limiting groove 3012 is 1-2 mm larger than the outer diameter of the second sleeve hole 3021, and the opening direction of its groove 30121 is on the same side as the hinge part 3013. When the second tube 302 is inserted into the limiting groove 3012, it can slide in along the groove 30121, and the outer wall of the second tube 302 fits and limits the groove wall of the limiting groove 3012. In this way, the contact area between the first tube 301 and the second tube 302 in the unfolded state is increased, avoiding deformation of the folding assembly 30 due to local stress concentration. Moreover, the same-side groove 30121 design ensures quick alignment during unfolding and prevents misalignment and detachment.

[0048] The end of the groove 30121 of the limiting tube groove 3012 is provided with a concave arc-shaped reinforcing part 30122. When the second tube 302 is repeatedly inserted into or removed from the limiting tube groove 3012, the arc-shaped reinforcing part 30122 on the limiting tube groove 3012 can distribute the force, improve the pressure resistance of the groove 30121, and extend the service life.

[0049] The upper ends of the first leg 10 and the second leg 11 are connected to a horizontal drying tube 40. Each leg can rotate around the drying tube 40 to unfold or fold. The drying tube 40 serves as a hanging area, allowing several drying hangers to be fitted onto the drying tube, providing overhead hanging space and expanding the drying function. It also serves as a central axis to improve the synchronization of leg unfolding and enhance the structural connection strength between the legs.

[0050] The drying horizontal tube 40 is equipped with several sliding hanging arms 50. One end of each sliding hanging arm 50 consists of a sliding sleeve 501 and an extension arm 502 with hanging holes 5021. The sliding hanging arm 50 is fitted onto the drying horizontal tube 40 via the sliding sleeve 501. The sliding hanging arm 50 can be manually slid, allowing it to slide back and forth along the axial direction of the drying horizontal tube 40, thereby adjusting its installation position. The adjustable position of the sliding hanging arm 50 allows, for example, the extension arm 502 to extend outwards from the angle between the first leg 10 and the second leg 11, accommodating different sizes of clothing and improving space utilization. The hanging holes 5021 are used to hang clothes hangers or hooks, and their design enables three-dimensional drying, meeting personalized needs.

[0051] In this embodiment, the legs are designed in a split manner. For example, the first leg 10 is divided into a first frame tube 101 and a first foot tube 102, and the second leg 11 is divided into a second frame tube 111 and a second foot tube 112. The split structure of the legs reduces the volume after folding, makes it easier to store, and reduces transportation and storage costs.

[0052] More specifically, the upper ends of the first frame tube 101 and the second frame tube 111 are hinged together by a folding seat 60, which is formed by the interlocking of a first folding block 601 and a second folding block 602. Furthermore, one end of each of the first and second folding blocks 601 and 602 is hinged together, while the other ends are respectively fitted onto the upper ends of the first frame tube 101 and the second frame tube 111. When unfolded, the two folding blocks rotate in a staggered manner to form an inverted V-shaped support structure; when folded, the two folding blocks rotate around the hinge point to retract. This allows the first leg 10 and the second leg 11 to be hinged together via the folding seat 60, enabling the unfolding and folding actions. The folding seat 60 also enhances the load-bearing capacity at the leg connection point, preventing deformation, and the interlocking design ensures the integrity of the unfolded state.

[0053] In addition, the lower ends of the first frame tube 101 and the second frame tube 111 are provided with insertion ends 1011 with spring fasteners 1012, and the upper ends of the first leg tube 102 and the second leg tube 112 are provided with corresponding fastening holes 1021. When the insertion end 1011 of the first frame tube 101 is inserted into the upper end of the first leg tube 102, and the insertion end 1011 of the second frame tube 111 is inserted into the upper end of the second leg tube 112, the spring fasteners 1012 are fastened into the corresponding fastening holes 1021 of the leg tubes, thereby locking the insertion state between the frame tube and the leg tube. When disassembling, pressing the spring fasteners 1012 can unlock and separate the frame tube and the leg tube.

[0054] Therefore, the plug-in design of the frame tube and the foot tube further reduces transportation and storage costs, and the spring-loaded fastener 1012 ensures the connection is stable, preventing accidental loosening during use, and simplifies the disassembly and assembly steps, improving the user's ease of operation.

[0055] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
