Description

Technical Field

[0001] The utility model relates to the field of sports equipment, in particular to an anti-winding rope output device. Background Art

[0002] Most of the power stations used for fitness currently use the method of adding and subtracting weights to adjust the size of the stretching force. The method of adding and subtracting weights is not only heavy and occupies a large area, but also lacks flexibility. Therefore, some manufacturers have recently begun to use servo motors to replace weights. The motor drives the reel wrapped with the pull rope to rotate to realize the pull rope in and out.

[0003] Specifically, the motor drives the cable reel to rotate synchronously. After the motor is started, it generates a positive force. When the force of the user pulling the rope is greater than the positive force of the motor, the cable reel reverses to release the rope, driving the motor to reverse, and the motor acts as a resistance to achieve the effect of exercise. When the force of the user pulling the rope is less than the positive force of the motor, the motor rotates forward, driving the cable reel to rotate forward to collect the rope.

[0004] However, when the device is just powered on, the motor will first reverse and learn to reset (this is controlled by the controller algorithm). Since there is no tension on the pull rope at this time (the user is not pulling the pull rope), the pull rope will be released from the reel, and the released pull rope is not pulled out from the rope outlet hole on the device housing. Therefore, it will remain in the device housing in a scattered manner, which is easy to get entangled inside the device and cause malfunctions.

[0005] In addition, when the user pulls the rope quickly, the cable reel and the motor will still reverse due to inertia, but the user's hand movements have stopped and the rope will not continue to be pulled out. In this case, the rotation of the cable reel will also cause the rope to gather and entangle inside the device. Utility Model Content

[0006] The purpose of the utility model is to provide a rope discharging device which is entanglement-proof so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0009] In some embodiments of the present application, the anti-entanglement rope-discharging device also includes a rope pressing assembly; the rope pressing assembly is arranged in the shell and on the outer side of the retaining ring, the rope pressing assembly includes a rope pressing strip and a connecting piece, the rope pressing strip presses the pull rope between the rope threading hole and the rope outlet hole, and the rope pressing strip is movably connected to the shell through the connecting piece, so that the rope pressing strip can move as the tension of the pull rope changes to tighten the pull rope.

[0010] In some embodiments of the present application, the two ends of the rope pressing strip are respectively a hinged end and a rope pressing end; the hinged end is rotatably connected to the shell; and the rope pressing end presses the pull rope between the rope threading hole and the rope outlet hole.

[0011] In some embodiments of the present application, the pressure rope end is bent in an arc shape.

[0012] In some embodiments of the present application, the rope pressure assembly further includes a gasket; the gasket is connected to the side of the rope pressure strip facing the cable reel, and the hinged end and the rope pressure end protrude out of the outside of the gasket.

[0013] In some embodiments of the present application, the connecting member includes a first magnetic member and a second magnetic member; the first magnetic member is connected to the pressure rope strip; the second magnetic member is connected to the shell; an attraction or repulsion force is generated between the first magnetic member and the second magnetic member to act on the pressure rope strip.

[0014] In some embodiments of the present application, the connecting member is a spring; one end of the spring is connected to the shell, and the other end is connected to the pressure rope.

[0015] In some embodiments of the present application, the retaining ring, the cable reel, the motor and the rope pressing assembly form a group of rope outlet structures; two rope outlet holes are provided on the shell, two groups of rope outlet structures are provided inside the shell, and the pull ropes on the two cable reels respectively pass through the two rope outlet holes to get out of the shell.

[0016] In some embodiments of the present application, the anti-entanglement rope-discharging device also includes a guide wheel and a reversing wheel; the guide wheel is rotatably disposed in the shell and on the outer side of the baffle ring, the guide wheel is close to the rope threading hole, and two guide wheels are provided; the reversing wheel is rotatably disposed in the shell and on the outer side of the baffle ring, the reversing wheel is close to the rope outlet hole; the pull rope passes through the two guide wheels and bypasses the reversing wheel to pass through the rope outlet hole to the outside of the shell; the anti-entanglement rope-discharging device also includes a limiter; the limiter is disposed outside the shell, the limiter is connected to the pull rope, and the size of the limiter is larger than the size of the rope outlet hole.

[0017] In some embodiments of the present application, the cable reel includes a first reel and a second reel coaxially connected to each other; the pull rope is wound on the first reel; the first reel is rotatably disposed in the retaining ring, and the second reel is rotatably disposed outside the retaining ring; the anti-entanglement rope output device also includes a transmission belt, and the transmission belt is connected to the second reel and the rotor of the motor.

[0018] It can be seen from the above technical solutions that the embodiments of the utility model have at least the following advantages and positive effects:

[0019] In the anti-entanglement rope output device of the embodiment of the utility model, when the power is just turned on, the motor drives the winding drum to reverse and output the rope, and the pull rope will be released from the winding drum, but because there is no tension on the pull rope, the pull rope will not be pulled out from the rope output hole.

[0020] 1. By setting a storage gap, and the width of the storage gap is set to be at least twice the diameter of the pull rope, when the pull rope is released from the winding drum, it will fall into the storage gap. Since the space width is relatively loose, the pull rope will not be stuck between the retaining ring and the winding drum, nor will it be entangled in the shell and cause malfunctions.

[0021] 2. Another preferred method is to provide a rope pressing assembly, and to press the rope between the rope outlet hole and the disengagement position through the rope pressing strip, which is equivalent to providing some resistance to the rope outlet. The existence of this resistance will cause the released rope to be divided into two parts, one part of which is still relatively regularly wound on the winding drum, but becomes relatively loose, but will not cause entanglement and cause failure in the shell. The other part stretches the rope between the rope outlet hole and the disengagement position. If the stretched rope between the rope outlet hole and the disengagement position is relatively scattered, it will cause entanglement and cause failure in the shell. The movement of the rope pressing strip can tighten the stretched rope between the rope outlet hole and the disengagement position, thereby avoiding the problem of entanglement and failure caused by the scattered rope. Similarly, when the user pulls the rope quickly, the rope pressing assembly can be used to prevent the rope from being scattered and entangled inside the shell, thereby reducing the failure rate of the device.

[0028] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0029] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0030] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0031] See also Figures 1 to 4 The anti-winding rope discharging device provided in one embodiment of the utility model comprises a housing 1, a winding drum 2 and a motor 3.

[0032] A retaining ring 5 is disposed inside the housing 1 , and a rope threading hole 51 is disposed on the retaining ring 5 . A rope outlet hole 11 is also disposed on the housing 1 and is located outside the retaining ring 5 .

[0033] The cable reel 2 is rotatably disposed in the retaining ring 5 . A pull rope 21 is wound on the cable reel 2 . The pull rope 21 passes through the retaining ring 5 from the rope threading hole 51 and passes through the housing 1 from the rope outlet hole 11 .

[0034] The motor 3 is arranged in the housing 1 and outside the retaining ring 5. The motor 3 drives the winding drum 2 to rotate forward to collect the rope or reverse to deliver the rope.

[0035] A storage gap for storing the pull rope 21 is formed between the winding drum 2 and the retaining ring 5, and the width of the storage gap is set to be at least twice the diameter of the pull rope.

[0036] When the power is just turned on, the motor 3 drives the cable reel 2 to reverse and unwind the cable, and the pull rope 21 will be released from the cable reel 2 . However, since there is no tension on the pull rope 21 , the pull rope 21 will not be pulled out from the cable outlet hole 11 .

[0037] By setting a storage gap, and the width of the storage gap is set to be at least twice the diameter of the pull rope, when the pull rope 21 is released from the winding drum 2, it will fall into the storage gap. Since the space width is relatively loose, the pull rope 21 will not get stuck between the retaining ring 5 and the winding drum 21, nor will it get entangled in the shell 1 and cause malfunctions.

[0038] The anti-entanglement rope-discharging device also includes a rope pressing assembly 4, which is arranged in the shell 1 and on the outside of the retaining ring 5. The rope pressing assembly 4 includes a rope pressing strip 41 and a connecting piece 42. The rope pressing strip 41 presses the pull rope 21 between the rope threading hole 51 and the rope outlet hole 11, and the rope pressing strip 41 is movably connected to the shell 1 through the connecting piece 42, so that the rope pressing strip 41 can move with the change of the tension of the pull rope 21 to tighten the pull rope 21.

[0039] By pressing the rope-pressing strip 41 to press the rope 21 between the rope-threading hole 51 and the rope-exiting hole 11, it is equivalent to providing some resistance to the rope-exiting of the rope 21. The existence of this resistance will cause the released rope 21 to be divided into two parts, one of which is still relatively regularly wound on the winding drum 2, but becomes relatively loose, but will not cause entanglement and cause failure in the housing 1. The other part stretches the rope 21 between the rope-threading hole 51 and the rope-exiting hole 11. If the stretched rope 21 between the rope-threading hole 51 and the rope-exiting hole 11 is relatively scattered, it will cause entanglement and cause failure in the housing 1. The stretched rope 21 between the rope-threading hole 51 and the rope-exiting hole 11 can be tightened by the movement of the rope-pressing strip 41, thereby avoiding the problem of entanglement and causing failure caused by the scattered rope 21. Similarly, when the user pulls the rope 21 quickly, the rope-pressing assembly 4 can also prevent the rope 21 from being scattered and gathered inside the housing 1, thereby reducing the failure rate of the device.

[0040] It should be noted that forward rotation and reverse rotation only represent two different rotation directions. For example, when forward rotation is clockwise, reverse rotation is counterclockwise, or when forward rotation is counterclockwise, reverse rotation is clockwise. That is, forward rotation and reverse rotation should not be limited to specific rotation directions.

[0041] Furthermore, the retaining ring 5 allows the pull cord 21 to be wound neatly on the cable drum 2, and only the loosened portion of the pull cord 21 is stored in the storage gap, further preventing the portion of the pull cord 21 from being entangled in the housing 1 and causing a malfunction. It is understood that after the pull cord 21 is separated from the cable drum 2, it passes through the retaining ring 5 through the rope threading hole 51.

[0042] The cable reel 2 includes a first reel 22 and a second reel 23 which are coaxially connected. A pull rope 21 is wound on the first reel 22. The first reel 22 is rotatably disposed in the retaining ring 5, and the second reel 23 is rotatably disposed outside the retaining ring 5. The anti-winding rope discharging device also includes a transmission belt 6, which is connected to the second reel 23 and the rotor of the motor 3. The rotor of the motor 3 drives the second reel 23 through the transmission belt 6 to synchronously drive the first reel 22 to rotate to achieve rope collection or rope discharging. A ring-shaped winding groove is also provided on the peripheral side of the first reel 22, and the pull rope 21 is wound in the winding groove, so that the pull rope 21 is orderly and regular.

[0043] The pressing rope strip 41 can be movably connected to the housing 1 in such a manner that the pressing rope strip 41 is rotatably connected to the housing 1 or the pressing rope strip 41 is movably connected to the housing 1. In this embodiment, the two ends of the pressing rope strip 41 are respectively a hinged end and a pressing rope end, and the hinged end is rotatably connected to the housing 1. The pressing rope end presses the drawstring 21 between the rope outlet hole 11 and the disengagement position T. In other words, the pressing rope strip 41 is rotatably connected to the housing 1, and the pressing rope strip 41 tensions the drawstring 21 by rotating. When the tension on the drawstring 21 is small, the pressing rope strip 41 rotates in the reverse direction to make the bending float of the drawstring 21 larger and keep the drawstring 21 tensioned. When the tension on the drawstring 21 is large, the pressing rope strip 41 rotates in the forward direction to make the drawstring 21 tend to be straight and keep the drawstring 21 tensioned. In other embodiments, the pressing rope strip 41 is movably connected to the housing 1, and the pressing rope strip 41 tensions the drawstring 21 by moving.

[0044] The end of the pressure rope is bent in an arc shape. On the one hand, it can avoid the problem that the contact resistance between the pressure rope end and the pull rope 21 is too large, resulting in the unsmooth pull rope 21. On the other hand, when the rotation angle of the pressure rope strip 41 changes, the pressure rope end can maintain a stable contact area with the pull rope 21.

[0045] As an embodiment of the connecting member 42, the connecting member 42 includes a first magnetic member 421 and a second magnetic member 422. The first magnetic member 421 is connected to the pressing rope strip 41. The second magnetic member 422 is connected to the housing 1.

[0046] The second magnetic member 422 is disposed on the side of the rope pressing strip 41 facing the winding reel 2, and the first magnetic member 421 and the second magnetic member 422 generate an attractive force to act on the rope pressing strip 41. The first magnetic member and the second magnetic member 422 can both be magnets with their own magnetic force, or one of the first magnetic member and the second magnetic member 422 can be a magnet with its own magnetic force, and the other can be a metal that can be attracted by magnetism.

[0047] In other embodiments, the second magnetic member 422 is disposed on the side of the rope pressing strip 41 facing away from the winding drum 2, and a repulsive force is generated between the first magnetic member 421 and the second magnetic member 422 to act on the rope pressing strip 41. Both the first magnetic member 422 and the second magnetic member 422 are magnets with their own magnetic force.

[0048] As another embodiment of the connecting member 42, the connecting member 42 is a spring, one end of which is connected to the housing 1, and the other end is connected to the pressing rope strip 41. The spring can be arranged on the side of the pressing rope strip 41 facing the winding drum 2, in which case the spring has a tensile force. The spring can also be arranged on the side of the pressing rope strip 41 facing away from the winding drum 2, in which case the spring has a compressive force.

[0049] The connecting member 42 is disposed at a position of the rope pressing strip 41 close to the hinged end, so that when the rope pressing end presses the pull rope 21 between the rope outlet hole 11 and the disengagement position T, the connecting member 42 will not cause interference.

[0050] The rope pressing assembly 4 also includes a gasket (not shown), which is connected to the side of the rope pressing strip 41 facing the winding drum 2, and the hinged end and the rope pressing end protrude out of the gasket. The rope pressing strip 41 can be a plastic part, and the gasket can be a soft pad, such as but not limited to a rubber pad. The gasket prevents the pull rope 21 from rubbing against the rope pressing strip 41 and causing wear. In addition, the gasket separates an elastic space between the rope pressing strip 41 and the winding drum 2 to ensure smooth rope output. The reason is that if the rope pressing strip 41 and the winding drum 2 are set too tightly, the rope output space will be squeezed, and the friction resistance will increase. If the distance between the rope pressing strip 41 and the winding drum 2 is too wide, the rope pressing effect of the rope pressing strip 41 may be poor. Therefore, by setting the gasket, an elastic space is provided, which ensures smooth rope output and the rope pressing effect. In this embodiment, the gasket is arranged on the side of the connecting member 42 close to the rope pressing end.

[0051] The anti-winding rope outlet device also includes a guide wheel 7 and a reversing wheel 8. The guide wheel 7 is rotatably disposed in the housing 1 and disposed on the outside of the retaining ring 5, and the guide wheel 7 is close to the rope threading hole 51. Two guide wheels 7 are provided. The reversing wheel 8 is rotatably disposed in the housing 1 and disposed on the outside of the retaining ring 5, and the reversing wheel 8 is close to the rope outlet hole 11. The pull rope 21 passes through the two guide wheels 7 and bypasses the reversing wheel 8 to pass through the rope outlet hole 11 outside the housing 1.

[0052] The two guide wheels 7 and the reversing wheel 8 make the pull rope 21 smoother during the process of pulling in or pulling out the rope. At the same time, the reversing wheel 8 plays the role of making the pull rope 21 pass through the rope outlet hole 11 out of the housing 1 after reversing.

[0053] The retaining ring 5, the cable reel 2, the motor 3 and the cable pressing assembly 4 form a set of cable outlet structures. Two cable outlet holes 11 are provided on the housing 1, and two sets of cable outlet structures are provided inside the housing 1. The pull ropes 21 on the two cable reels 2 pass through the two cable outlet holes 11 to the outside of the housing 1. The two pull ropes 21 pass through the outside of the housing 1 and are connected to the two handles respectively. The user can hold the two handles with both hands to exercise.

[0054] The anti-entanglement rope outlet device also includes a limiter. The limiter is arranged outside the housing 1, the limiter is connected to the pull rope 21, and the size of the limiter is larger than the size of the rope outlet hole 11. Therefore, the limiter cannot pass through the rope outlet hole 11 into the housing 1, so that the limiter can prevent the pull rope 21 from being completely retracted into the housing 1. The limiter can be a handle, or it can be an additional component added between the handle and the rope outlet hole 11. In this embodiment, a set of rope outlet structures also includes a retaining ring 5, a transmission belt 6, two guide wheels 7 and a reversing wheel 8.

[0055] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
