In addition, the tighter the spiral spring 61 contracts, the more elastic potential energy the spiral spring 61 has).

[0035] In this way, the handle 5 drives the rotating shaft 53 to rotate, the rotating shaft 53 drives the winding wheel 52 to rotate synchronously, and the rotation of the winding wheel 52 can take in and release the towing line 21 wound around the winding wheel 52; one end of the first towing rope 11 is connected to the clothes hanger 4, and the other end of the first towing rope 11 is connected to the towing line 21; the first towing rope 11 is supported and slid on the pulley assembly for conveying; the taking in and releasing of the towing line 21 can drive the clothes hanger 4 to lift and lower through the first towing rope 11; when the clothes hanger 4 descends, during the rotation of the rotating shaft 53, the spiral spring 61 contracts and stores elastic potential energy, that is, a part of the potential energy of the clothes hanger 4 is converted into the elastic potential energy of the spiral spring 61; when the clothes hanger 4 ascends, the spiral spring 61 expands and assists the user to push the rotating shaft 53 to rotate to drive the clothes hanger 4 to ascend, that is, the elastic potential energy of the spiral spring 61 is converted into the gravitational potential energy of the clothes hanger 4, saving the user's effort.

[0036] Among them, the spiral spring 61 stores elastic potential energy when it is tightened and releases elastic potential energy when it expands.

[0038] Specifically, in one embodiment, when the winding wheel 52 rotates in the first direction, the clothes hanger 4 ascends and the spiral spring 61 contracts. Specifically, in one embodiment, when the winding wheel 52 rotates in the second direction (the second direction is opposite to the first direction), the spiral spring 61 expands.

[0039] Specifically, in one embodiment, the first towing rope 11 can be wound around the first fixed pulley 33 for more than one turn. Specifically, in one embodiment, the first towing rope 11 can be wound around the first fixed pulley 33 for less than one turn.

[0046] Specifically, in one embodiment, the clockwork spring 61 is wound around the rotating shaft 53.

[0047] Further, please refer to Figures 1 to 5, as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, the housing 54 has a receiving cavity, and the clockwork spring 61 is disposed in the receiving cavity. In this way, the clockwork spring 61 is protected in the receiving cavity of the housing 54 to prevent it from being knocked by external objects.

[0048] Further, please refer to Figures 1 to 5 , as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, a first slot adapted to the inner end of the clockwork spring 61 is provided on the rotating shaft 53, and a second slot adapted to the outer end of the clockwork spring 61 is provided on the housing 54; the inner end of the clockwork spring 61 is inserted into the first slot, and the other end of the clockwork spring 61 is inserted into the second slot. In this way, the clockwork spring 61 can be very conveniently connected to the rotating shaft 53 and the housing 54 respectively.

[0049] Further, please refer to Figures 1 to 5 , as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, the inner end of the clockwork spring 61 is flat and coplanar with the axis of the rotating shaft 53. In this way, when the inner end of the clockwork spring 61 is clamped in the first slot, it is not easy for the rotating shaft 53 to slip with the clockwork spring 61 during the process of driving the inner end of the clockwork spring 61 to rotate.

[0050] Further, please refer to Figures 1 to 5 , as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, the edge of the outer end of the clockwork spring 61 is bent. In this way, when the bent outer end of the clockwork spring 61 is clamped in the second slot, the clockwork spring 61 is not easy to separate from the second slot. Specifically, in one embodiment, the outer end of the clockwork spring 61 extends along the extension direction of the rotating shaft 53, so that when the clockwork spring 61 is sleeved on the rotating shaft, it can be inserted into the second slot along with the rotating shaft 53, and the installation is very convenient.

[0051] Further, please refer to Figures 1 to 5 , as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, it further includes a first hanging member 13 for hanging the clothes hanger 4; the first hanging member 13 is connected to the first traction rope 11. In this way, it is convenient to install / separate from the clothes hanger 4 through the first hanging member 13.

[0052] Further, please refer to Figures 1 to 5 , as a specific implementation of the elastic energy storage clothes hanger provided by the present invention, the pulley assembly includes a first hanging seat 31, a second hanging seat 32, a first fixed pulley 33 provided on the first hanging seat 31, and a second fixed pulley 34 provided on the second hanging seat 32; the first traction rope 11 is sequentially wound around the first fixed pulley 33 and the second fixed pulley 34. In this way, the first traction rope 11 can be supported / transported by the first fixed pulley 33 and the second fixed pulley 34. In addition, the first fixed pulley 33 and the second fixed pulley 34 can also adjust the direction of the first traction rope 11.

[0053] Further, please refer to Figures 1 to 5 , as a specific embodiment of the elastic energy storage clothes hanger provided by the present invention, it further includes a third suspension seat 35, a third fixed pulley 36 arranged on the third suspension seat 35, a second traction rope 12 wound around the third fixed pulley 36 and the second fixed pulley 34, and a second hanging member 14 for hanging the clothes hanger 4; one end of the second traction rope 12 is connected to the second hanging member 14, and the other end of the second traction rope 12 is connected to the traction line 21. Thus, when the traction line 21 expands and contracts, it drives the second traction rope 12 to expand and contract, and the expansion and contraction of the second traction rope 12 drives the second hanging member 14 to rise and fall, and the clothes hanger 4 rises and falls more smoothly under the cooperation of the first hanging member 13 and the second hanging member 14.

[0054] Specifically, in one embodiment, the second fixed pulley 34 is provided with a first annular slot 341 and a second annular slot 342; the first traction rope 11 is clamped in the first annular slot 341, and the second traction rope 12 is clamped in the second annular slot 342. Thus, the first traction rope 11 is clamped in the first annular slot 341, and the second traction rope 12 is clamped in the second annular slot 342, making it difficult for the first traction rope 11 and the second traction rope 12 to interfere with each other.

[0055] Specifically, in one embodiment, it further includes a connecting member 7; the first traction rope 11 is fixed to the traction line 21 through the connecting member 7; and / or the second traction rope 12 is fixed to the traction line 21 through the connecting member 7. Thus, the first traction rope 11 and the second traction rope 12 are connected to the connecting member 7, facilitating the traction line 21 to simultaneously retract and release the first traction rope 11 and the second traction rope 12 through the connecting member 7.

[0056] Specifically, in one embodiment, a fourth fixed pulley 37 is arranged on the first suspension seat 31, and the second traction rope 12 is wound around the fourth fixed pulley 37. Thus, the first traction rope 11 cooperates with the first fixed pulley 33 on the first suspension seat 31, and the second traction rope 12 cooperates with the fourth fixed pulley 37 on the first suspension seat 31, making it difficult for the first traction rope 11 and the second traction rope 12 to interfere with each other.

[0057] Further, please refer to Figures 1 to 5 , as a specific embodiment of the elastic energy storage clothes hanger provided by the present invention, the clothes hanger 4 is annular. Thus, the annular clothes hanger 4 is convenient for drying.

[0058] Specifically, please refer to Figures 6 to 12, in one embodiment, the first fixed pulley 33 is flat, and a flat storage cavity 81 adapted to the shape of the first fixed pulley 33 is provided on the first suspension seat 31, and the first fixed pulley 33 is arranged in the storage cavity 81. In this way, the first fixed pulley 33 can be protected by the storage cavity 81, and the first fixed pulley 33 is easy to keep its own orientation unchanged under the limitation of the flat storage cavity 81.

[0059] Specifically, in one embodiment, a wire inlet hole and a wire outlet hole for the first towing rope 11 to pass through are formed on the inner wall of the storage cavity 81.

[0060] Specifically, in one embodiment, a baffle 82 is arranged outside the wire inlet hole, and a wire passing hole 821 for the first towing rope 11 to pass through is formed on the baffle 82. In this way, the first towing rope 11 passing through the wire passing hole 821 can play a guiding role for the first towing rope 11. Specifically, in one embodiment, the included angle between the baffle 82 and the first towing rope 11 is less than 70°. In this way, when the first towing rope 11 vibrates along the wire passing hole 821 or when the first towing rope 11 passes through the wire passing hole 821, the rubbing between the first towing rope 11 and the edge of the wire passing hole 821 is reduced.

[0061] Specifically, in one embodiment, the wire passing hole 821 is a long strip hole. In this way, the first towing rope 11 can swing along the long strip hole.

[0062] Specifically, in one embodiment, a protective cover 83 is provided to cover the bottom of the first suspension seat 31. In this way, the first suspension seat 31 is protected by the protective cover 83. Specifically, in one embodiment, the protective cover 83 is hemispherical and opens upward.

[0063] Specifically, in one embodiment, it further includes a hollow columnar body 84 and a sleeve 85 sleeved outside the columnar body 84. The columnar body 84 is detachably clamped on the inner wall of the sleeve 85 through a buckle mechanism; an installation hole is formed on the protective cover 83, and the sleeve 85 is inserted into the installation hole; a limiting flange 86 is arranged on the sleeve 85 outside the protective cover 83; an external thread is arranged on the outer side wall of the sleeve 85, and an assembly hole communicating with the storage cavity 81 is formed on the first suspension seat 31, and the assembly hole has an internal thread matching with the above external thread; the protective cover 83 is clamped between the limiting flange 86 and the first suspension seat 31. In this way, the protective cover 83 maintains the stability of its own position under the clamping of the limiting flange 86 and the first suspension seat 31. In this way, the first towing rope 11 on the first fixed pulley 33 in the storage cavity 81 passes through the assembly hole and then reaches outside the protective cover 83 through the hollow columnar body 84.

[0064] Specifically, in one embodiment, the snap mechanism includes a positioning groove 841 and a protrusion; the positioning groove 841 is provided on the outer surface of the columnar body 84, and the positioning groove 841 extends along the axial direction of the columnar body 84. The protrusion is provided on the inner wall of the sleeve 85, and the protrusion is clamped in the positioning groove 841. In this way, when the sleeve 85 is sleeved on the columnar body 84, the protrusion is inserted into the positioning groove 841 to position the sleeve 85 and the columnar body 84; if it is necessary to separate the columnar body 84 and the sleeve 85, only the protrusion needs to be slid out of the positioning groove 841.

[0065] Specifically, in one embodiment, a columnar spring 87 is clamped between the columnar body 84 and the first suspension seat 31. In this way, the looseness of the columnar body 84 is reduced.

[0066] Specifically, in one embodiment, the end of the hollow columnar body 84 has a cavity 842 communicating with the hollow channel, and the columnar spring 87 is inserted into the cavity 842. In this way, the columnar spring 87 is not easily detached from the columnar body 84 under the condition of being vibrated under the positioning of the cavity 842.

[0067] Specifically, in one embodiment, a self-locking mechanism for self-locking the winding wheel 52 (self-locking: the user does not drive the rotating shaft 53 to rotate through the handle) is further included.

[0068] Specifically, in one embodiment, the self-locking mechanism includes: a cylinder body 91 disposed on the winding wheel 52 and sleeved on the rotating shaft 53, a torsion spring 92 sleeved on the cylinder body 91 and in a contracted state, a cover body 93 disposed on the housing 54 and having a columnar cavity for accommodating the torsion spring 92, a limiting groove 94 opened on the side surface of the cylinder body 91 and extending along the extending direction of the rotating shaft 53, and a convex platform 95 disposed on the winding wheel 52 and extending into the limiting groove 94; the outer surface of the torsion spring 92 abuts against the inner wall of the columnar cavity, both ends of the torsion spring 92 are respectively clamped in the limiting groove 94 and hooked on the two side walls of the limiting groove 94, and both ends of the torsion spring 92 are respectively located on the moving paths of the opposite sides of the convex platform 95.Thus, a cylinder body 91 is provided on the winding wheel 52, and the cylinder body 91 is coaxially arranged with the winding wheel 52; a limiting groove 94 is provided on the outer surface of the cylinder body 91, and the limiting groove 94 extends along the extending direction of the cylinder body 91; a torsion spring 92 is sleeved on the cylinder body 91, and both ends of the torsion spring 92 are respectively clamped in the limiting groove 94, and the torsion spring 92 is in a tightened state; the torsion spring 92 is received in the columnar cavity of the housing 54, and the outer side wall of the torsion spring 92 abuts against the inner wall of the columnar cavity; so that when the torsion spring 92 unfolds freely, the outer diameter of the torsion spring 92 is greater than the inner diameter of the columnar cavity; both ends of the torsion spring 92 are respectively clamped in the limiting groove 94, and the first end 921 of the torsion spring 92 is hooked on one side wall of the limiting groove 94, and the second end 922 of the torsion spring 92 is hooked on the other side wall of the limiting groove 94; when the winding wheel 52 rotates, the winding wheel 52 drives the cylinder body 91 to rotate. Since the torsion spring 92 is in a tightened state and abuts against the inner wall of the columnar cavity, the torsion spring 92 is stationary relative to the columnar cavity when the cylinder body 91 starts to rotate, that is, the torsion spring 92 does not rotate with the cylinder body 91 when the cylinder body 91 starts to rotate (the static friction force between the torsion spring 92 and the inner wall of the columnar cavity prevents the torsion spring 92 from rotating with the cylinder body 91); the cylinder body 91 either pulls the first end 921 to move towards the second end 922 to further tighten the torsion spring 92, or the cylinder body 91 either pulls the second end 922 to move towards the first end 921 to further tighten the torsion spring 92; the more the torsion spring 92 is tightened, the smaller the outer diameter of the torsion spring 92 becomes, and the contact force between the torsion spring 92 and the inner wall of the cylinder body 91 decreases as the cylinder body 91 rotates, until the cylinder body 91 directly pulls the torsion spring 92 to rotate with the cylinder body 91 through the first end 921, or the cylinder body 91 directly pulls the torsion spring 92 to rotate with the cylinder body 91 through the second end 922; and when the winding wheel 52 does not rotate, the cylinder body 91 is in a stationary state. Whether the boss 95 between the first end 921 of the torsion spring 92 and the second end 922 of the torsion spring 92 pushes the first end 921 in the direction away from the second end 922, or the boss 95 pushes the second end 922 in the direction away from the first end 921, the distance between the first end 921 and the second end 922 increases, which will expand the torsion spring 92. The greater the distance between the first end 921 and the second end 922, the greater the torsion spring 92 is expanded, and the larger the outer diameter of the torsion spring 92 becomes. Since the torsion spring 92 abuts against the inner wall of the columnar cavity, the expanded torsion spring 92 will contact the inner wall of the columnar cavity more closely, resulting in that the torsion spring 92 is difficult to rotate with the rotation of the boss 95 and brakes the boss 95. The boss 95 is provided on the winding wheel 52, and the boss 95 naturally brakes the winding wheel 52.

[0069] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
