Description

Technical Field

[0001] This utility model relates to the field of drying tools, and in particular to a folding clothes rack that can expand drying space. Background Technology

[0002] Folding clothes racks are drying tools designed to be foldable or extendable, reducing space usage and facilitating storage and transport, making them popular. For example, Chinese utility model patent CN209128757U, entitled "An X-shaped Floor-Standing Clothes Rack," includes two sets of support frames and two sets of crossbars. The two sets of support frames are connected by connecting rods. Each support frame has an X-shaped structure. The two ends of each crossbar are fixedly connected to the top of the same side of both support frames. The two sets of support frames support two crossbars to form an X-shaped clothes rack. A rotating connector connects the upper and lower support rods. The rotating connector has two centrally symmetrical connector heads with joints. The rotating connectors of the two support components engage and rotate in opposite directions. The joints of the rotating connectors provide a stop and fixation, avoiding additional torque when the clothes rack is open. This ensures the entire structure's load-bearing capacity is concentrated on the X-shaped structure, resulting in a stable structure and convenient use.

[0003] However, the existing technology still has the following drawbacks:

[0004] 1. When existing clothes drying racks are unfolded and used, the horizontal bars and connecting rods of their support components are installed using a fixed connection method. The length of the horizontal bars and connecting rods determines the drying space, which limits the flexibility and expandability of use.

[0005] 2. The existing clothes drying rack uses a spliced ​​connector structure for the rotating joint between the upper and lower support rods. This structure is prone to damage during repeated folding and use, and is difficult to maintain and repair, with high replacement costs. Moreover, the clothes drying rack is still quite large after being folded and stored, and the transportation costs remain high. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a folding clothes rack with expandable drying space.

[0007] The purpose of this utility model is achieved by the following technical solution: a folding clothes rack with expandable drying space, including a support leg assembly and a first drying structure. The first drying structure has a first connecting seat, a first drying rod, and a second drying rod. The first connecting seat has a clamp and a rotating arm. The clamp has a connecting tube, a clamping groove, and a positioning part. The two ends of the first drying rod are respectively assembled with the connecting tube of the clamp. The clamp is detachably clamped to the support leg assembly through the clamping groove. One end of the rotating arm is movably sleeved on the connecting tube of the clamp and can rotate around the connecting tube. The other end of the rotating arm is connected to the second drying rod. The rotating arm has a positioning block on the side close to the positioning part of the clamp, so that when the rotating arm and the second drying rod rotate around the connecting tube to the drying position, the positioning block abuts against the positioning part of the clamp for positioning.

[0008] Furthermore, the support assembly has a first support and a second support that are hinged to each other, and the first drying structure is provided on the first support and / or the second support.

[0009] Furthermore, the upper and lower ends of the clamp are respectively provided with connecting shafts and fasteners, and are respectively inserted into the mounting holes on the first leg and / or the second leg through the connecting shafts, and the edges of the first leg and / or the second leg are fastened by the fasteners.

[0010] Furthermore, the first leg and the second leg are hinged together by a hinge seat. The upper and lower ends of the hinge seat are staggered and have insertion holes. The first leg is divided into upper and lower sections and is assembled with the insertion holes at the upper and lower ends of the hinge seat. A limiting cavity is opened in the middle of the hinge seat, which extends through both sides. The second leg extends through and is hinged to the limiting cavity, so that the second leg can be unfolded or folded with the first leg within the space defined by the limiting cavity.

[0011] Furthermore, a reinforcing block is provided on the adjacent side of the clamping groove of the clamping seat, and the positioning part is provided on the surface of the reinforcing block.

[0012] Furthermore, one end of the rotating arm is provided with a sliding sleeve, which is rotatably sleeved on the connecting pipe of the clamp seat. The surface of the connecting pipe is provided with an anti-dislodgement component to prevent the sliding sleeve from sliding out axially into the connecting pipe. The other end of the rotating arm is provided with a pipe hole for assembly with both ends of the second drying rod.

[0013] Furthermore, the surface of the clamp has several finger grooves arranged in parallel for hand gripping.

[0014] Furthermore, the folding clothes rack with expandable drying space also includes a second drying structure having a third drying rod, which is detachably mounted on the upper end of the first and / or second legs.

[0015] Furthermore, the second drying structure also has a second connecting seat, which has a fixed end and a turning end that moves the fixed end. The fixed end of the second connecting seat is fixedly connected to the first support leg and the second support leg. The turning end of the second connecting seat has a sleeve hole through which the third drying rod is sleeved.

[0016] Furthermore, telescopic drying rods are provided at both ends of the third drying rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) The embodiments of this application provide a first drying structure, whose clamp is quickly assembled and conveniently replaced by setting a clamping groove and a support leg assembly; the clamp is connected to the first drying rod and the rotating arm by setting a connecting pipe, and the rotating arm can be rotated around the connecting pipe. The second drying rod is connected to the rotating arm, and then rotates around the connecting pipe of the clamp together with the second drying rod connected to it; so that when the second drying rod is rotated to the horizontal drying position by the rotating arm, the second drying rod and the first drying rod are roughly on the same horizontal plane, forming a horizontal double-layer drying space, breaking the traditional fixed rod length limitation, and realizing flexible expansion of the drying space; and the positioning block abuts against the positioning part of the clamp, so that the second drying rod is rotated open to maintain a more stable use state, and forms a protective positioning mechanism to prevent excessive rotation, which meets the requirements for safe use; when rotated and stored, the second drying rod and the support leg are kept parallel, greatly reducing the storage volume and reducing transportation costs.

[0033] The present invention will now be further described in conjunction with 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.

[0034] like Figure 1-9As shown, a folding clothes rack with expandable drying space includes a support leg assembly 10 and a first drying structure 20. The support leg assembly 10 serves as the basic support structure of the folding clothes rack. The support leg assembly 10 is formed by the first support leg 101 and the second support leg 102 being cross-hinged to each other through a hinge seat 104 to form an X-shaped support structure.

[0035] The upper and lower ends of the hinge base 104 are staggered left and right and have corresponding insertion holes. The upper and lower sections of the first leg 101 are inserted into the corresponding insertion holes. A limiting cavity 1041 is opened in the middle of the hinge base 104. The second leg 102 passes through the limiting cavity 1041 and is hinged by a pin. Assembly is only required by passing the second leg 102 through the limiting cavity 1041, making replacement and assembly more convenient. The limiting cavity 1041 restricts the second leg 102 to rotate only within a set angle (0-45°). That is, the maximum angle between the second leg 102 and the first leg 101 in the unfolded state is 45°, and they are parallel to each other in the folded state, thus avoiding structural damage caused by over-expansion or folding collision.

[0036] Therefore, this application embodiment provides an integrated hinge seat 104 to replace the traditional multi-part splicing connector structure, simplifying the connection structure between the first leg 101 and the second leg 102, reducing wear points, facilitating maintenance, improving the torsional strength of the leg assembly 10, reducing replacement costs, and extending the service life of the folding clothes rack. In addition, through the staggered insertion hole design at the upper and lower ends of the hinge seat 104, the first leg 101 and the second leg 102 can completely overlap after being folded, reducing the folding thickness from the previous 3 tube thickness to about 2 tube thickness.

[0037] The first drying structure 20 has a first connecting seat 201, a first drying rod 2014 and a second drying rod 2015. The first connecting seat 201 has a clamp 2011 and a rotating arm 2012. The clamp 2011 has a connecting pipe 20112, a clamping groove 20111 and a positioning part 20131. The connecting pipe 20112 is located on one side of the upper end of the clamp 2011. The clamping groove 20111 is U-shaped. A reinforcing block 2013 is provided on the outside of the clamping groove 20111. The positioning part 20131 is integrated into the surface of the reinforcing block 2013. The reinforcing block 2013 is provided on the outside of the clamping groove 20111, which can reduce the deformation of the rotating arm 2012 during positioning and improve the bending strength of the clamp 2011.

[0038] During installation, the first drying rod 2014 is fixedly inserted into the connecting pipe 20112 of the clamp 2011 at both ends, thus completing the assembly of the first drying rod 2014 and the clamp 2011. The clamp 2011 can be detachably clamped onto the first support leg 101 and the second support leg 102 through the clamping groove 20111, which facilitates the replacement of the support leg of the clamp 2011 without damage.

[0039] The two ends of the rotating arm 2012 are respectively provided with a sliding sleeve 20122 and a pipe hole 20123. One end of the rotating arm 2012 is movably sleeved on the outside of the connecting pipe 20112 through the sliding sleeve 20122, and can rotate around the connecting pipe 20112. At this time, the clamp 2011 can still maintain the state of clamping the support foot, so that the assembly of the first drying structure 20 and the support foot is more stable, and at the same time, the rotation movement of the rotating arm 2012 is stable.

[0040] The other end of the rotating arm 2012 is assembled with the second drying rod 2015 through the pipe hole 20123; a positioning block 20121 is integrally protruding on the side of the rotating arm 2012 near the reinforcing block 2013. Therefore, the rotating arm 2012, together with the second drying rod 2015, can rotate circumferentially around the connecting pipe 20112 through the sliding sleeve 20122. When the rotating arm 2012 is rotated to the drying position, it is positioned by the positioning block 20121 abutting against the positioning part 20131 on the reinforcing block 2013. At this time, the first drying rod 2014 and the second drying rod 2015 are approximately on the same horizontal plane.

[0041] Thus, this application embodiment provides a first drying structure 20, whose clamp 2011 is quickly assembled with the support leg assembly 10 through the clamping groove 20111, making replacement convenient; the clamp 2011 is connected to the first drying rod 2014 and the rotating arm 2012 through the connecting pipe 20112, and the rotating arm 2012 can rotate circumferentially around the connecting pipe 20112; the second drying rod 2015 is connected to the rotating arm 2012, and thus, together with the second drying rod 2015 connected thereto, it rotates around the connecting pipe 20112 of the clamp 2011; so that when the second drying rod 2015 is rotated to the horizontal drying position through the rotating arm 2012, the second drying rod 2015 and the first drying rod 2014 are roughly on the same horizontal plane, forming a horizontal double-layer drying space, breaking the traditional fixed rod length limitation, and realizing flexible expansion of the drying space;

[0042] The positioning block 20121 abuts against the positioning part 20131 of the clamp 2011, so that the second drying rod 2015 can be flipped open to maintain a more stable use state and form a protective positioning mechanism to prevent excessive flipping and meet the requirements for safe use. When flipped for storage, the second drying rod 2015 and each support leg remain parallel, which greatly reduces the storage volume and reduces transportation costs.

[0043] The clamp 2011 provided in this application embodiment is provided with a connecting shaft 20114 and an elastic fastener 20115 at its upper and lower ends, respectively. When the clamp 2011 is clamped with the first support leg 101 and the second support leg 102 through the clamping groove 20111, it is also inserted into the mounting hole 103 on the support leg through the connecting shaft 20114 at its upper end. Moreover, the elastic fastener 20115 is provided on the side of the clamping groove 20111 and is used to fasten the edge of the support leg inward, thereby realizing quick disassembly and assembly, facilitating the replacement of the drying structure, and further improving the installation stability of the first drying structure 20 and the support leg.

[0044] The surface of the connecting pipe 20112 of the clamp 2011 is provided with an anti-detachment protrusion 20113. After the sliding sleeve 20122 of the rotating arm 2012 is fitted onto the connecting pipe 20112, the anti-detachment protrusion 20113 is screwed onto the surface of the connecting pipe 20112 to prevent the sliding sleeve 20122 from falling off axially and to ensure that the rotating arm 2012 can be safely rotated on the clamp 2011.

[0045] The surface of the clamp 2011 is also provided with 3-4 parallel finger grooves 20116, which facilitate daily hand operation, especially when the hand grips and applies force to disassemble and assemble the clamp 2011.

[0046] The folding clothes rack also includes a second drying structure 30, which has a third drying rod 301 and a second connecting seat 302. The second connecting seat 302 has a fixed end 3021 and a turning end 3022. The fixed end 3021 is inserted into the top of the first support leg 101 and the second support leg 102 through a socket. The turning end 3022 is hinged to the upper part of the fixed end 3021. When the folding action is performed, the turning end 3022 and the fixed end 3021 are at a 90° angle.

[0047] A sleeve hole 30221 is provided on the turning end 3022, through which the third drying rod 301 is movably connected. The addition of the third drying rod 301 further expands the drying area. Moreover, when unfolded for use, the third drying rod 301 is mounted on the top of the support leg via the second connecting seat 302; when folded, the third drying rod 301 can still be assembled on the turning end 3022 after the turn, and the third drying rod 301 is brought together with the support leg, further reducing the folded area. Figure 9 As shown.

[0048] In addition, the two ends of the third drying rod 301 are nested with stretchable telescopic drying rods 3011 (such as the inner rod with a spring pin locking). The length of the telescopic drying rod 3011 is freely adjustable to adapt to different clothing sizes and further expand the drying area, thus improving the flexibility of use.

[0049] The operation and usage of the folding clothes drying rack in this embodiment are as follows:

[0050] In the unfolded state, the first support leg 101 and the second support leg 102 unfold into an X-shaped support structure. The clamp 2011 can hold the clamping groove 20111 clamped on the support leg. The rotating arm 2012 is flipped to the drying position, and the positioning block 20121 abuts against the positioning part 20131 of the clamp 2011, so that the second drying rod 2015 unfolds to be roughly at the same level as the first drying rod 2014. The third drying rod 301 is sleeved onto the second connecting seat 302 at the top of the support leg, and the telescopic drying rod 3011 is pulled out and extended. Figure 6 As shown.

[0051] Fold and store; flip the rotating arm 2012 to align with the clamp 2011, causing the second drying rod 2015 to flip until it is on the same storage plane as the support leg; retract the telescopic drying rods 3011 at both ends of the third drying rod 301; push the first support leg 101 and the second support leg 102 to close, with the limiting cavity 1041 constraining the folding angle; finally, it is closed into a flat state, as shown. Figure 8 As shown.

[0052] In addition, there is another folding and storage method: The clamp 2011 is removed from the support leg to store the first drying rod 2014 and the second drying rod 2015; the telescopic rod is retracted, and the third drying rod 301 is removed from the second connecting seat 302. The turning end 3022 of the first connecting seat 201 is flipped so that the turning end 3022 and the fixed end 3021 are at a 90° angle. Then, the third drying rod 301 is inserted into the sleeve hole 30221 of the turning end 3022, so that the third drying rod 301 and the support leg are folded together; finally, it is stored in a square strip shape, such as... Figure 9 As shown.

[0053] 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.
