Description

Technical Field

[0001] This invention relates to the field of sports assistive equipment technology, specifically to a skating traction device. Background Technology

[0002] With the popularization of winter sports and the continuous improvement of competitive levels, scientific and efficient training methods are crucial for improving athletes' skating speed, explosive power, and technical precision. In skating training, traction training is a common and effective auxiliary method that helps athletes experience high-speed skating without having to exert full force, or strengthens specific muscle groups during resistance / assisted training.

[0003] However, existing skating towing devices or similar land or ice towing equipment still have the following major technical problems in practical applications:

[0004] Insufficient traction accuracy and responsiveness: Traditional traction equipment often uses ordinary motors or hydraulic drives, lacking high-precision speed and torque control. During training, it is often unable to quickly adjust the magnitude and direction of the traction force according to the athlete's real-time gliding state, resulting in a significant reduction in training effectiveness and even the possibility of athlete injury due to sudden changes in traction force.

[0005] In existing devices, the rope exit position is often fixed when retracting or extending the rope, while the rope winding position on the drum is dynamically changing. This structure causes the rope to easily generate a large deflection angle when entering and exiting the drum, which not only exacerbates the friction and wear between the rope and the guide components and shortens the service life of the traction rope, but also affects the stability of the traction force due to fluctuations in friction. Therefore, we propose an ice skating traction device. Summary of the Invention

[0006] The purpose of this invention is to provide an ice skating traction device to solve the problems that need to be addressed in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an ice skating traction device, comprising a support frame and a traction rope, wherein the traction rope is a Dyneema rope, multiple sets of universal self-locking wheels are fixedly connected to the bottom of the support frame, a detachable operating box is attached to the top of the support frame, a support mechanism for supporting and limiting the support frame is provided on one side of the support frame, a drive winding and unwinding mechanism for winding and unwinding the traction rope is provided inside the operating box, a wire harness guiding mechanism for guiding the traction rope is provided inside the operating box and at the front end of the drive winding and unwinding mechanism, and a linkage drive mechanism for driving the wire harness guiding mechanism to follow the operation of the drive winding and unwinding mechanism is provided between the drive winding and unwinding mechanism and the wire harness guiding mechanism.

[0008] Existing skating traction devices or similar land or ice traction equipment still suffer from the following major technical problems in practical applications: Insufficient traction accuracy and responsiveness: Traditional traction devices mostly use ordinary motors or hydraulic drives, lacking high-precision speed and torque control. During training, they often cannot quickly adjust the magnitude and direction of the traction force according to the athlete's real-time skating status, resulting in a significant reduction in training effectiveness and even the possibility of athlete injury due to sudden changes in tension. In existing devices, the rope exit position is often fixed when retracting or extending the rope, while the rope winding position on the drum is dynamically changing. This structure causes the rope to easily generate a large deflection angle when entering and exiting the drum, which not only aggravates the friction and wear between the rope and the guide components but also shortens the service life of the traction rope. The control box of this invention is detachably mounted on the support frame, facilitating the separation and maintenance of the entire device. The subsequently installed drive winding and unwinding mechanism can drive the winding and unwinding of the Dyneema rope, and the winding and unwinding speed can be adjusted to suit different training intensities. The installed wire harness guiding mechanism guides the Dyneema rope during winding and unwinding, preventing excessive concentration of the rope during winding and unwinding. The linked drive mechanism synchronously drives the wire harness guiding mechanism while the winding and unwinding mechanism is operating, saving a power source and ensuring the accuracy of synchronous drive operation. The bottom of the support frame is equipped with multiple sets of universal self-locking wheels for flexible movement and positioning on ice or land. Furthermore, the side of the support frame has a support mechanism that provides additional support and limits during operation, preventing the device from sliding.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-6 This invention provides a technical solution: an ice skating traction device, including a support frame 1 and a traction rope. The traction rope is a Dyneema rope, which has the characteristics of high strength and low elongation, making it suitable for high-load traction training. The bottom of the support frame 1 is fixedly connected to multiple sets of universal self-locking wheels 2. The top of the support frame 1 is attached to a detachable operation box 3. A support mechanism 4 for supporting and limiting the support frame 1 is provided on one side of the support frame 1. The operation box 3 is equipped with a drive winding and unwinding mechanism 5 for winding and unwinding the traction rope. Inside the operation box 3 and at the front end of the drive winding and unwinding mechanism 5, a wire harness guiding mechanism 6 for guiding the traction rope is provided. A linkage drive mechanism 7 for driving the wire harness guiding mechanism 6 to operate in conjunction with the drive winding and unwinding mechanism 5 is provided between the drive winding and unwinding mechanism 5 and the wire harness guiding mechanism 6.

[0036] The control box 3 is detachably mounted on the support frame 1, facilitating the separation and maintenance of the entire device. The drive winding and unwinding mechanism 5 drives the winding and unwinding of the Dyneema rope, and the winding and unwinding speed of the Dyneema rope can be adjusted by the drive winding and unwinding mechanism 5, which is convenient for users to use for training of different intensities. The wire harness guide mechanism 6 guides the Dyneema rope during winding and unwinding, preventing the Dyneema rope from being overly concentrated. The linkage drive mechanism 7 drives the wire harness guide mechanism 6 simultaneously when the drive winding and unwinding mechanism 5 is working, saving a power source and ensuring the accuracy of synchronous drive operation. The bottom of the support frame 1 is equipped with multiple sets of universal self-locking wheels 2, which facilitate flexible movement and positioning on ice or land. In addition, the side of the support frame 1 is equipped with a support mechanism 4, which provides additional support and limit during the operation of the entire device to prevent the device from sliding.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The control box 3 includes a lower box body 8 and an upper cover body 12. Two sets of lifting handles 16 are fixedly connected to both sides of the lower box body 8. A first connecting hook 9 is fixedly connected to both sides of the lower box body 8. A first locking hook 10 connected to the first connecting hook 9 is provided on the support frame 1. The upper cover body 12 is rotatably connected to one side of the top of the lower box body 8 through a hinge piece 11. A second connecting hook 13 is fixedly connected to both ends of the upper cover body 12. A second locking hook 14 connected to the second connecting hook 13 is fixedly connected to both ends of the lower box body 8. A wire groove 15 is opened through one side of the upper cover body 12.

[0038] The lower housing 8 is mounted on top of the support frame 1 via a first connecting hook 9 and a first locking hook 10, facilitating the disassembly and maintenance of the operating box 3. The lower housing 8 and the upper cover 12 are then connected via a second connecting hook 13 and a second locking hook 14, allowing the lower housing 8 and the upper cover 12 to be opened via a hinge plate 11 for maintenance of their internal components. The cable channel 15 allows the Dyneema cable to extend from inside the operating box 3.

[0039] Please see Figures 1-6The drive take-up and unwind mechanism 5 includes a drive motor 18, a coupling 19, a first fixed frame 20, and a take-up and unwind roller 21. The drive motor 18 is fixedly installed inside the lower housing 8 via a mounting base 17. The drive motor 18 is configured as a servo motor. An electrical box 39 is fixedly installed inside the lower housing 8. The electrical box 39 is equipped with a mechanism for adjusting the speed of the drive motor 18, which is configured as a servo motor, to adapt to different training intensities. The electrical box 39 also houses a battery for the operation of the drive motor 18. The output end of the drive motor 18 is fixedly connected to the coupling 19. The first fixed frame 20 is fixedly installed inside the lower housing 8. The take-up and unwind roller 21 is rotatably connected to the first fixed frame 20. Dyneema rope is fixedly installed outside the take-up and unwind roller 21. One end of the coupling 19 is fixedly connected to the take-up and unwind roller 21.

[0040] When it is necessary to wind up the Dyneema rope, the drive motor 18 uses a coupling to drive the take-up and unwinding drum 21 to rotate, which can easily drive the Dyneema rope to rotate, thus facilitating the take-up and unwinding operation.

[0041] Please see Figures 1-6 The wire harness guiding mechanism 6 includes a second fixed frame 22, a reciprocating lead screw 23, a lead screw sleeve 24, a limiting slide bar 25, a limiting slider 26, and a connecting piece 27. Two sets of second fixed frames 22 are fixedly installed inside the lower housing 8 and in front of the take-up and unwinding roller 21. The reciprocating lead screw 23 is rotatably connected to the second fixed frame 22. The lead screw sleeve 24 is threadedly connected to the outside of the reciprocating lead screw 23. The limiting slide bar 25 is rotatably connected to the second fixed frame 22 and above the reciprocating lead screw 23. The limiting slider 26 is slidably connected to the outside of the limiting slide bar 25. The connecting piece 27 is fixedly connected to one side of the lead screw sleeve 24 and the limiting slider 26. The connecting piece 27 has a wire hole 28 for the Dyneema rope to pass through.

[0042] When the winding and unwinding mechanism 5 is in operation, the linkage drive mechanism 7 can be used to drive the reciprocating screw 23 to rotate. The Dyneema rope passes through the inside of the wire hole 28. The rotating reciprocating screw 23 can be driven by the screw sleeve 24 to swing left and right through the connecting piece 27 and the wire hole 28, which are limited by the limiting slide bar 25 and the limiting slider 26, so that the Dyneema rope can be wound up evenly and comprehensively along the outside of the winding and unwinding drum 21.

[0043] Please see Figures 1-6 The top of the take-up and unwind roller 21 is on the same horizontal plane as the wire guide hole 28 and the wire guide groove 15. Both sides of the wire guide hole 28 are provided with arc-shaped chamfers. The arc-shaped chamfers can prevent the Dyneema rope from being excessively scratched when it passes through the connecting piece 27 at an angle. Moreover, the fact that the top of the take-up and unwind roller 21 is on the same horizontal plane as the wire guide hole 28 and the wire guide groove 15 can also prevent the Dyneema rope from being excessively scratched.

[0044] Please see Figures 1-6 The linkage drive mechanism 7 includes a first synchronous pulley 29, a second synchronous pulley 30, a first synchronous belt 31, a third synchronous pulley 32, a fourth synchronous belt pulley 33, and a second synchronous belt 34. The other end of the take-up and unwinding roller 21 is fixedly connected to the first synchronous pulley 29. One end of the limiting slide rod 25 is fixedly connected to the second synchronous pulley 30. The first synchronous belt 31 is provided outside the first synchronous pulley 29 and the second synchronous pulley 30. The other end of the limiting slide rod 25 is fixedly connected to the third synchronous pulley 32. One end of the reciprocating screw 23 is fixedly connected to the fourth synchronous belt pulley 33. The second synchronous belt 34 is provided outside the third synchronous pulley 32 and the fourth synchronous belt pulley 33.

[0045] The rotating take-up and unwind roll 21 can drive the first synchronous pulley 30 to rotate. The first synchronous pulley 30, which then rotates, can drive the second synchronous pulley 30, the limiting slide bar 25, and the third synchronous pulley 32 to rotate via the first synchronous belt 31. The third synchronous pulley 32, which then rotates, can drive the fourth synchronous pulley 33 and the reciprocating lead screw 23 to rotate via the second synchronous belt 34, thereby driving the wire harness guide mechanism 6 to swing left and right.

[0046] Please see Figures 1-6 The support mechanism 4 includes a hinge seat 35, a support leg 36, a positioning rod 37, and a positioning frame 38. The hinge seat 35 is fixedly connected to the support frame 1, and the support leg 36 is rotatably connected to the hinge seat 35. The positioning rod 37 is fixedly connected to the support frame 1 and located below the hinge seat 35. The positioning frame 38, which is engaged with the positioning rod 37, is rotatably connected to the support leg 36.

[0047] When it is necessary to limit the support on one side of the support frame 1, the support leg 36 is pulled to rotate and open along the hinge seat 35, and then the positioning frame 38 is inserted into the outside of the positioning rod 37. In this way, the support leg 36 can be used to maintain the stability of the entire support frame 1.

[0048] In use, the control box 3 is detachably mounted on the support frame 1, facilitating easy separation and maintenance of the entire device. The drive mechanism 5, which drives the winding and unwinding of the Dyneema rope, allows for adjustment of the winding and unwinding speed, facilitating training at different intensities. The cable guide mechanism 6 guides the Dyneema rope during winding and unwinding, preventing excessive concentration of the rope. The linkage drive mechanism 7 synchronously drives the cable guide mechanism 6 while the drive mechanism 5 is operating, saving on a separate power source and ensuring synchronized operation. The accuracy of operation is ensured by the multiple sets of universal self-locking wheels 2 at the bottom of the support frame 1, which facilitates flexible movement and positioning on ice or land. Furthermore, the support frame 1 has a support mechanism 4 on its side, providing additional support and limiting during operation to prevent slippage. The lower housing 8 is mounted on top of the support frame 1 via a first connecting hook 9 and a first locking hook 10, facilitating the disassembly and maintenance of the operating box 3. The lower housing 8 and the upper cover 12 are then connected via a second connecting hook 13 and a second locking hook 14, allowing the lower housing 8 and the upper cover 12 to be opened via a hinge plate 11 for maintenance of their internal components. The cable tray 15 provides convenient access to the cable tray. The Dyneema rope extends from inside the control box 3. When it is necessary to wind the Dyneema rope, the drive motor 18 drives the take-up and unwinding drum 21 to rotate via a coupling. This facilitates the rotation of the Dyneema rope, making the take-up and unwinding operations convenient. When the take-up and unwinding mechanism 5 is in operation, the linkage drive mechanism 7 drives the reciprocating screw 23 to rotate. The Dyneema rope passes through the wire guide hole 28. The rotating reciprocating screw 23 can be driven by the screw sleeve 24 to swing left and right through the connecting piece 27 and the wire guide hole 28, which are limited by the limit slide rod 25 and the limit slider 26. This allows the Dyneema rope to be wound evenly and comprehensively along the outside of the take-up and unwinding drum 21. The rotating take-up and unwind roll 21 can drive the first synchronous pulley 30 to rotate. The rotating first synchronous pulley 30 can then drive the second synchronous pulley 30, the limiting slide bar 25, and the third synchronous pulley 32 to rotate via the first synchronous belt 31. The rotating third synchronous pulley 32 can then drive the fourth synchronous pulley 33 and the reciprocating lead screw 23 to rotate via the second synchronous belt 34, thereby driving the wire harness guide mechanism 6 to swing left and right. When it is necessary to limit and support one side of the support frame 1, the support leg 36 is pulled to rotate and open along the hinge seat 35. Then, the positioning frame 38 is inserted into the outside of the positioning rod 37. In this way, the support leg 36 can be used to maintain the stability of the entire support frame 1.
