Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings: Example
[0028] A sturdy folding drying rack, such as Figure 1-9 As shown, it includes a fixed base 1; a movable panel 2 is provided at the front end of the fixed base 1; the fixed base 1 and the movable panel 2 are connected by a folding frame 3; fixed ends 4 are also fixedly provided at both ends of the fixed base 1; an elastic winding shaft 5 is provided inside the fixed base 1 and rotatably installed between the two fixed ends 4; a drying net 6 is also provided between the fixed base 1 and the movable panel 2, one end of the drying net 6 is fixedly connected to the movable panel 2, and the other end of the drying net 6 is fixedly wound onto the elastic winding shaft 5; a side of the movable panel 2 away from the fixed base 1 is provided with... The pull rod 7 has connecting protrusions at both ends on the side near the movable panel 2. The connecting protrusions at both ends are fixedly connected to the two ends of the movable panel 2 by connecting bolts 71. The movable panel 2 is also provided with protective blocks 8 at both ends. One side of the protective block 8 is provided with a locking block 81 that engages with the movable panel 2. The locking block 81 is fixedly connected to the movable panel 2 by connecting pins. The lower surface of the movable panel 2 is provided with a second insertion groove 21. The lower end of the protective block 8 is provided with a second insertion block 82 that engages with the second insertion groove 21 at the lower end of the movable panel 2.
[0029] The folding frame 3 includes two folding rods 31 located between the fixed base 1 and the movable panel 2, respectively fixedly hinged to both ends of the fixed base 1 and the movable panel 2; a sliding rod 32 is provided between the two folding rods 31 and slides with the two folding rods 31; each folding rod 31 includes a first connecting rod 311 fixedly hinged to one end of the fixed base 1 and a second connecting rod 312 fixedly hinged to one end of the movable panel 2; a slider 313 is provided between the first connecting rod 311 and the second connecting rod 312, with the opposite ends of the first connecting rod 311 and the second connecting rod 312 respectively fixedly hinged to both sides of the slider 313; the slider 313 slides with the sliding rod 32, and a sliding sleeve 314 is fixedly provided on the inner side of the slider 313 at the sliding engagement point with the sliding rod 32; the sliding rod 32 includes a rod body 321 that slides with the slider 313, with anti-disengagement buckles 322 fixedly fastened to both ends of the rod body 321; two limiting blocks 323 are fixedly sleeved in the middle section of the rod body 321.
[0030] Working principle:
[0031] When this utility model of a clothes drying rack is unfolded, the user pulls the movable panel 2 outward via the pull rod 7. The movable panel 2 causes the folding rack 3 to extend synchronously. The first connecting rod 311 and the second connecting rod 312 of the two folding rods 31 gradually unfold with the slider 313 as the hinge point. At this time, the slider 313 slides along the axis of the sliding rod 32, the sliding sleeve 314 reduces the frictional resistance, and the anti-disengagement buckles 322 at both ends of the sliding rod 32 and the limiting blocks 323 form a sliding range to ensure a stable unfolding trajectory. As the movable panel 2 moves, the clothes drying net 6 is pulled out from the elastic winding shaft 5 and unfolded. The outer shaft 52 rotates under the action of traction force, causing the spring 54 between the inner rod 51 and the outer shaft 52 to undergo torsional deformation and store elastic potential energy. After unfolding, the first connecting rod 311 and the second connecting rod 312 of the folding rods 31 are in a straight line. At this time, the retraction force of the elastic retractor 5 acts on a straight line formed by the first connecting rod 311 and the second connecting rod 312, and is at a dead point position, so that the moving panel 2 remains stationary; clothes or other items can be laid flat on the drying net 6 for drying; when the drying is finished and the drying rack needs to be retracted, pull the lever 7, and then push the folding rods 31 on both sides inward to break the dead point position of the folding rods 31. Then release the lever 7, and the elastic restoring force of the spring 54 drives the outer shaft 52 to rotate in the opposite direction, pulling the drying net 6 to automatically retract to the surface of the elastic retractor 5; at this time, the folding rack 3 folds back synchronously under the action of the drying net retraction force, the slider 313 slides back to the initial position along the slider 32, the folding rod 31 is completely folded into the lower cavity of the fixed base 1, and the moving panel 2 is tightly attached to the fixed base 1 to complete the storage.
[0032] The fixing base 1 is a basic support structure, internally divided into upper and lower chambers by a partition 11, which respectively accommodate the elastic winding shaft 5 and the folding frame 3. The fixing ends 4 at both ends of the fixing base 1 are matched with the upper and lower chambers of the fixing base 1 by protrusions 41, ensuring the stability of the structure. At the same time, the lower end of the fixing end 4 is provided with a first insertion block 42, which cooperates with the first insertion groove 13 on the fixing base 1 to enhance the connection firmness. The rear sides of both ends of the fixing base 1 are also designed with snap-fit grooves 14, which are interlocked with the snap-fit blocks 43 on the fixing ends 4, which not only simplifies the fixing process but also... The assembly process of the base 1 and the fixed end 4 improves the assembly efficiency and significantly enhances the connection tightness between the fixed end 4 and the fixed base 1. At the same time, one end of the drying net 6 is fixedly connected to the movable panel 2, and the other end is connected to the elastic winding shaft 5 through the buckle 9. The buckles 9 are evenly distributed on the elastic winding shaft 5, which facilitates the assembly and disassembly of the drying net 6 and ensures that the connection between the drying net 6 and the elastic winding shaft 5 is firm and reliable. In addition, in order to prevent the buckles 9 from rotating on the elastic winding shaft 5, a limiting protrusion is also provided on the elastic winding shaft 5, which plays an effective limiting role.
[0033] If the gap between the movable panel 2 and the fixed ends 4 at both ends of the fixed base 1 is too large, it will affect the aesthetics. If it is too small, the length tolerance of the movable panel 2 needs to be strictly controlled, which will increase the processing difficulty and make it easy to scratch the fixed ends 4 during the retraction and extension process, affecting the smoothness. By setting protective blocks 8 at both ends of the movable panel 2, the gap can be appropriately widened to avoid the trouble caused by excessive processing precision, and scratches can be prevented to ensure smooth retraction and extension. At the same time, safety is improved and the aesthetic effect is maintained.
[0034] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
