DETAILED DESCRIPTION

[0026] The present invention will be further described below in conjunction with specific embodiments and drawings.

[0027] Example 1

[0028] refer to Figure 1 and Figure 7 As shown, a safe and anti-fall clothes drying machine includes a frame 1, a lifting component 2, a lifting rod 3 and a safety rope 4.

[0029] The rack 1 is a fixed frame that provides a mounting and supporting basis for other functional components. The rack 1 is mainly fixed to the mounting base 6 (the mounting base can be a floor, ceiling, beam or crossbar) through the hanging assembly 5. The rack 1 is provided with a lifting assembly 2, which is connected to a lifting rod 3. The lifting rod 3 is a rod-shaped structure for hanging clothes, and the lifting assembly 2 is used to provide power for the lifting rod 3 to move up and down.

[0030] The lifting assembly 2 may be a drum-type lifting assembly, that is, the lifting rope (which may be a rope or chain made of various materials) is wound around the drum to pull up or lower the lifting rod 3. The lifting assembly 2 may also be a folding-link lifting assembly, which converts the folding or unfolding of the connecting rod into the raising or lowering of the lifting rod through a plurality of parallel hinged four-link rods.

[0031] A retractable safety rope 4 is provided between the frame 1 and the lifting rod 3. The lower end of the safety rope 4 is connected and fixed to the lifting rod 3. The safety rope 4 moves synchronously with the lifting rod 3. The safety rope 4 is used to add a safety guarantee for the lifting rod 3. The safety rope 4 has an elongation margin and can be retracted synchronously with the lifting of the lifting assembly without affecting the normal movement of the lifting rod. When the force applied to the lifting rod exceeds the support limit of the lifting assembly 2, the lifting rod 3 will fall. At this time, the safety rope 4 is used to limit the falling position of the lifting rod 3 to avoid falling or reduce the damage caused by falling.

[0032] The long edge of the rack 1 is provided with an upward L-shaped flange 101, so that the clothes drying machine is consistent with the appearance of the ceiling, which can improve the aesthetics. In addition, a clamping convex part is also provided on the flange 101, and the edge of the rack 1 can also be clamped on the clamping seat to further improve the stability of the clothes drying machine.

[0033] Example 2

[0034] refer to Figure 2 As shown, a safe and fall-proof clothes drying machine is optimized based on Example 1.

[0035] The safety rope 4 is an elastic safety rope 401, the upper end of which can be directly connected and fixed to the frame 1, or the upper ends of the elastic safety ropes 401 on both sides can be connected to each other to form a safety rope pulling structure.

[0036] The elastic safety rope 401 is pulled and stretched when the lifting rod 3 is lowered, and is rebounded and shortened when the lifting rod 3 is raised. Since the elastic safety rope 401 cannot be infinitely stretched, the elastic safety rope 401 limits the lifting rod 3 when it is fully stretched to prevent it from falling.

[0037] Example 3

[0038] refer to Figure 3 As shown, a safe and fall-proof clothes drying machine is optimized based on Example 1.

[0039] The retractable end of the safety rope 4 is wound and connected with the first drum 411, and the first drum 411 is rotatably arranged on the frame 1, and a spring 412 is arranged between the first drum 411 and the frame 1. The retractable end of the safety rope 4 is realized by the rotation of the first drum 411.

[0040] When the lifting rod 3 rises or falls, the first drum 411 overcomes or uses the elastic force of the spring 412 to release or retract the safety rope 4. Similarly, since the spring 412 has an elastic limit, the spring 412 limits the lifting rod 3 at the elastic limit position to prevent it from falling.

[0041] Example 4

[0042] refer to Figure 4 As shown, a safe and fall-proof clothes drying machine is optimized based on Example 1.

[0043] The retractable end of the safety rope 4 is wound and connected with the second drum 423, and the second drum 423 is fixed on the lifting transmission shaft 422. The lifting transmission shaft 422 is also fixed with a lifting drum 421, and the lifting drum 421 is wound and connected with the retractable end of the lifting rope 424. The fixed end of the lifting rope 424 is fixedly connected to the lifting rod 3.

[0044] The second drum 423 and the lifting drum 421 have the same diameter and specification to ensure that when the lifting motor drives the lifting transmission shaft 422 to rotate, the second drum 423 and the lifting drum 421 have the same linear speed, that is, the safety rope 4 and the lifting rope 424 have the same retraction and release speed.

[0045] At the same time, the pre-released length of the safety rope 4 is a little longer than the released length of the lifting rope 424, that is, in normal circumstances, the lifting rod 3 is lifted by the tightened lifting rope 424, and the safety rope 4 is relatively released to ensure relaxation. When the lifting rope 424 fails and the lifting rod 3 falls, the safety rope 4 immediately replaces the lifting rope 424 to achieve lifting and avoid falling.

[0046] Or the end of the safety rope 4 adopts an elastic transition section, and the middle section adopts a rigid material, so that the safety rope 4 is looser than the lifting rope 424. However, when the lifting rope 424 fails to pull, the safety rope 4 can replace the lifting rope 424 to avoid falling.

[0047] Or the frame 1 is provided with an elastic tensioning wheel supporting the safety rope 4 to realize elastic tensioning of the safety rope 4, so as to keep the safety rope 4 more relaxed relative to the lifting rope 424. When the lifting rope 424 fails to pull, the safety rope 4 can replace the lifting rope 424 to avoid falling.

[0048] Example 5

[0049] refer to Figure 5 As shown, a safe and fall-proof clothes drying machine is optimized based on Example 1.

[0050] The retractable end of the safety rope 4 is wound and connected with the third drum 431, and the third drum 431 is fixed on the safety transmission shaft 433. The safety transmission shaft 433 is connected with the lifting transmission shaft 422 through the differential 432. The lifting drum 421 is fixed on the lifting transmission shaft 422. The lifting drum 421 is wound and connected with the retractable end of the lifting rope 424, and the fixed end of the lifting rope 424 is fixedly connected to the lifting rod 3.

[0051] When the lifting motor drives the lifting transmission shaft 422 to rotate, the safety transmission shaft 433 is also rotated through the differential 432. Due to the differential effect of the two drums, the third drum 431 has a greater linear speed than the lifting drum 421, so that the safety rope 4 can be released a longer length relative to the lifting rope 424, and the safety rope 4 remains loose and does not affect the lifting of the lifting rod 3. When the lifting rope 424 fails and the lifting rod 3 falls, the safety rope 4 immediately replaces the lifting rope 424 to achieve lifting and avoid further falling.

[0052] Example 6

[0053] refer to Figure 6As shown, a safe and fall-proof clothes drying machine is optimized based on Example 1.

[0054] A multi-directional balance suppression component is provided on the frame 1, and the multi-directional balance suppression component is connected to the safety rope 4. When one end of the lifting component fails (the rope breaks), the gravity of the lifting rod 3 and the clothes thereon will act on the multi-directional balance suppression component through the safety rope 4. Due to the unilateral failure, the multi-directional balance suppression component is subjected to force on one side, and the balance is broken at this time. The multi-directional balance suppression component then suppresses the falling of the safety rope 4 to achieve fall prevention.

[0055] Preferably, the retracted end of the safety rope 4 is wound and connected with the fourth drum 441, and the fourth drum 441 is arranged on the lifting transmission shaft 422. An elastic transmission sleeve 442 (such as a rubber sleeve) is provided between the fourth drum 441 and the lifting transmission shaft 422. The elastic transmission sleeve 442 can ensure the transmission friction between the lifting transmission shaft 422 and the fourth drum 441, but under the action of unilateral tension, the elastic transmission sleeve 442 is compressed, thereby realizing the relative displacement of the fourth drum 441.

[0056] When the lifting motor drives the lifting transmission shaft 422 to rotate, the transmission shaft drives the fourth drum 441 to rotate synchronously, so as to realize the retraction and release of the safety rope 4. When the lifting assembly fails and the safety rope 4 is under load, since the fourth drum 441 is pulled in a single direction and the elastic transmission sleeve 442 is compressed, the fourth drum 441 tilts in that direction. The frame 1 is provided with a friction pad 443 located on the side of the fourth drum 441, and the fourth drum 441 and / or the friction pad 443 are provided with an uneven friction surface. At this time, the fourth drum 441 is pressed against the friction pad 443, and is locked by friction, thereby tightening the safety rope 4 to realize overall anti-falling.

[0057] After the lifting component is repaired or replaced, the lifting rod 3 is lifted again, and the fourth drum 441 is restored to the equilibrium position under the elastic force of the elastic transmission sleeve 442. The fourth drum 441 can still rotate synchronously with the lifting transmission shaft 422 to restore the synchronous retraction and release action of the safety rope 4.

[0058] The above basic examples and further optional examples of the utility model can be freely combined to form multiple embodiments, which are all embodiments that can be adopted and claimed for protection by the utility model. In the scheme of the utility model, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
