Description

Technical Field

[0001] This application relates to the field of ice skating machine technology, and in particular to an adjustable safety device for ice skating machines. Background Technology

[0002] In the field of skating, skating movements and techniques are very important. Skating machines can be used to train basic skating techniques, fundamental figure skating techniques, and various individual ice hockey techniques. Especially in competitive sports such as ice hockey, the most important skating skill is the ability to accelerate instantly, that is, to reach the fastest speed in the shortest amount of time while standing still. A professional ice hockey player needs to reach full speed within three to five steps.

[0003] One related technology involves an ice skating machine comprising a machine body and a handrail frame. The machine body has a continuously rotating ice skating board on it. The handrail frame is fixed to the ground and has handrails for athletes to hold onto. During use, athletes stand on the continuously rotating ice skating board and practice techniques such as instantaneous acceleration, skating balance, or turning, according to their training goals. Athletes can adjust their center of gravity by gripping the handrails to avoid falling due to loss of balance during the skating process.

[0004] In the process of developing this application, at least the following problems were found in the technology: the height of the handrail is fixed, but due to differences in the height and arm length of athletes, shorter athletes need to deliberately raise their arms to stably grip the handrail, which can easily lead to shoulder muscle strain in the long run; taller athletes need to bend over to adapt to the height of the handrail, which disrupts the standard body posture when skating and affects the training accuracy of techniques such as instant acceleration; at the same time, improper gripping posture will also reduce the support stability of gripping the handrail and increase safety hazards during training. Utility Model Content

[0005] To facilitate the adjustment of the handrail height to accommodate athletes of different heights and arm lengths, this application provides an adjustable safety device for an ice skating machine.

[0006] The adjustable safety device for an ice skating machine provided in this application adopts the following technical solution: An adjustable safety device for an ice skating machine includes a handrail frame and a handrail bar. A set of slide rails are symmetrically and fixedly installed on both sides of the handrail frame. Several insertion holes are evenly spaced along the vertical direction on the slide rails. One end of the handrail bar slides vertically in one of the slide rails, and the other end of the handrail bar slides vertically in another slide rail. A pin corresponding to the slide rail is provided inside the handrail bar. The pin slides along the length of the handrail bar and is connected to the handrail bar. The pin extends from the end of the handrail bar and is inserted into any insertion hole on the corresponding slide rail.

[0007] By adopting the above technical solution, when it is necessary to adjust the height of the handrail, first pull the pin along the length of the handrail to disengage the pin from the socket on the slide rail. The slide rail and the handrail are no longer constrained, and the handrail can then slide vertically along the slide rail. After adjusting to a height suitable for the athlete's height and arm length, release the pin and reinsert it into the corresponding socket on the slide rail to re-fix the handrail. This allows for flexible adjustment of the handrail height to meet the needs of athletes of different heights and arm lengths, avoiding arm strain for shorter athletes and back hunching for taller athletes, ensuring standard skating posture, and improving the training accuracy of techniques such as instantaneous acceleration.

[0008] Preferably, a fixing block corresponding to the pin is fixedly installed inside the handrail, and a thrust spring is provided between the fixing block and the pin. One end of the thrust spring abuts against the pin, and the other end of the thrust spring abuts against the fixing block. The thrust spring drives the pin away from the fixing block.

[0009] By adopting the above technical solution, the thrust spring always applies a spring force away from the fixed block to the pin, so that the pin tends to extend out of the end of the handrail. When adjusting the height of the handrail, it is only necessary to overcome the spring force to pull the pin to disengage it from the socket. After the adjustment is in place, the pin is released, and the spring force can automatically push the pin into the socket, while ensuring the stability of the pin in the socket and preventing the pin from accidentally disengaging and causing the handrail to loosen.

[0010] Preferably, the handrail is provided with a connecting rod corresponding to the pin. One end of the connecting rod is fixedly connected to the pin, and the other end of the connecting rod is fixedly provided with a lever. The lever has an inclined surface on the side near the corresponding pin. A button is provided through and slidably on the side wall of the handrail. The button is located between the two levers and simultaneously abuts against the two inclined surfaces.

[0011] By adopting the above technical solution, when it is necessary to pull the pin, press the button inside the handrail. The button presses the inclined surface of the two levers. Under the guidance of the inclined surface, the levers drive the connecting rod to move away from the slide rail, thereby pulling the two pins to simultaneously disengage from the insertion holes of the slide rails on both sides. In this way, when adjusting the height of the handrail, there is no need for other people to go to the vicinity of the slide rail to adjust the handrail. Athletes can stand on the skating machine (i.e., the position of use) and directly adjust the height of the handrail, which makes it convenient for athletes to quickly try whether the adjusted handrail height is appropriate.

[0012] Preferably, the handrail is fitted with a sliding sleeve, which slides along the length of the handrail and is engaged with the handrail. The end of the sliding sleeve has a protective groove for the button to be inserted.

[0013] By adopting the above technical solution, when there is no need to adjust the handrail during training, the sliding sleeve allows the button to extend into the protective groove, and the side wall of the sliding sleeve covers the button, preventing the pin from coming off due to accidental button touch by the athlete during training, thus ensuring safety during training; when the handrail needs to be adjusted, the sliding sleeve exposes the button for operation, without affecting the normal adjustment function of the button.

[0014] Preferably, the handrail is provided with a rotating ring, and the side wall of the rotating ring is provided with a threaded groove. The end of the sliding sleeve can extend into the threaded groove and be threadedly connected to the threaded groove.

[0015] By adopting the above technical solution, when the sliding sleeve is moved to the position of covering or exposing the button, the rotating ring drives the threaded groove to rotate, so that the end of the sliding sleeve is threadedly engaged with the threaded groove, thereby fixing the position of the sliding sleeve and preventing the button from being exposed due to accidental slippage of the sliding sleeve during training. This ensures the stability of the sliding sleeve's protective function and further improves the reliability of its use.

[0016] Preferably, the button is provided with a first roller corresponding to the inclined surface, and the peripheral wall of the first roller abuts against the inclined surface.

[0017] By adopting the above technical solution, the first roller converts the sliding friction between the button and the inclined surface of the toggle into rolling friction, reducing the resistance when the button is pressed and reducing the frictional wear of the contact surface between the button and the toggle. This avoids the increase in the fit clearance due to wear after long-term and frequent operation, and prevents problems such as asynchronous adjustment of the pin and jamming.

[0018] Preferably, movable blocks are fixedly provided at both ends of the handrail, and a second roller is rotatably provided on the movable block, the second roller rolling in the slide rail.

[0019] By adopting the above technical solution, the second roller converts the sliding friction between the handrail and the slide rail into rolling friction, reducing the resistance when the handrail slides vertically, making it easier for athletes to adjust the height of the handrail. At the same time, the rolling of the roller can ensure that the handrail moves stably along the slide rail, avoiding tilting or jamming during the sliding process, and improving the stability of the adjustment process.

[0020] Preferably, a safety rope is provided on the handrail.

[0021] By adopting the above technical solution, athletes can attach safety ropes to appropriate parts of their bodies, such as the waist, or connect them to their sportswear during training. Even if an athlete loses balance on the ice skateboard, the safety rope can provide additional tension to prevent them from falling, further reducing safety hazards during training and improving safety.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up handrail frames, handrails, slide rails, sockets, pins, fixing blocks, and push springs, when the height of the handrail needs to be adjusted, first pull the pin along the length of the handrail to disengage the pin from the socket on the slide rail. The slide rail and the handrail are no longer constrained, and the handrail can then slide vertically along the slide rail. After adjusting to a height suitable for the athlete's height and arm length, release the pin and re-insert it into the corresponding socket on the slide rail to re-fix the handrail. This allows for flexible adjustment of the handrail height to meet the needs of athletes of different heights and arm lengths. 2. By setting up a connecting rod, lever, inclined surface, button, and first roller, pressing the button and using the guiding effect of the inclined surface, the two levers drive the connecting rod and the pin to move synchronously. This allows a single person to unlock the pin synchronously while standing in the skating machine's operating position, without the need for others to operate beside the skating rail. This makes it easier for athletes to quickly try and adjust to the optimal height. 3. By setting up a sliding sleeve, protective groove, rotating ring, and threaded groove, when there is no need to adjust the handrail during training, the sliding sleeve slides to make the button extend into the protective groove, the side wall of the sliding sleeve covers the button, and the rotating ring rotates to drive the threaded groove to rotate, so that the end of the sliding sleeve is threadedly engaged with the threaded groove, fixing the position of the sliding sleeve and preventing the pin from coming off due to the athlete accidentally touching the button during training, thus ensuring safety during training.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses an adjustable safety device for an ice skating machine. (See also...) Figure 1 It includes a handrail frame 1 and a handrail 2. The handrail frame 1 is a metal bracket fixedly installed on the ground. A set of slide rails 11 are symmetrically installed on both sides of the handrail frame 1 and fixed by welding, that is, there is one slide rail 11 on each side of the handrail frame 1. Several insertion holes 111 are evenly and spaced along the vertical direction on the side wall of the slide rail 11.

[0030] Reference Figure 1 One end of the handrail 2 slides vertically within one slide rail 11, and the other end slides vertically within another slide rail 11. Specifically, movable blocks 27 are welded and fixed to the outer walls at both ends of the handrail 2. Second rollers 271 are rotatably mounted on the movable blocks 27. The second rollers 271 roll within the slide rails 11, providing guidance for the vertical movement of the handrail 2 and reducing friction during the vertical movement of the handrail 2.

[0031] Reference Figure 1 and Figure 3 The handrail 2 is provided with a pin 21 corresponding to the slide rail 11. The pin 21 slides along the length of the handrail 2. Specifically, each end of the handrail 2 has a circular hole with a circular cross-section along its own length. The pin 21 is cylindrical and fits into the circular hole and slides in cooperation. The pin 21 extends out of the circular hole at the end of the handrail 2 and is inserted into any of the holes 111 on the corresponding slide rail 11.

[0032] Reference Figure 1 and Figure 3 A fixing block 22 corresponding to the pin 21 is fixedly installed inside the round hole of the handrail 2. The fixing block 22 is located on the side of the pin 21 near the middle of the handrail 2. A thrust spring 23 is provided between the fixing block 22 and the pin 21. One end of the thrust spring 23 abuts against the pin 21 and is welded and fixed, and the other end of the thrust spring 23 abuts against the fixing block 22 and is welded and fixed. The thrust spring 23 drives the pin 21 away from the fixing block 22. The thrust spring 23 always applies a spring force to the pin 21 away from the fixing block 22, so that the pin 21 tends to extend out of the end of the handrail 2, ensuring the stability of the pin 21 extending into the insertion hole 111.

[0033] To make it easier for athletes to stand on the skating machine, the height of handrail 2 can be directly adjusted, referring to... Figure 3 and Figure 4The handrail 2 has a square hole with a rectangular cross-section in its middle along its length, and the end of the square hole communicates with a round hole. A connecting rod 24 corresponding to a pin 21 is provided inside the handrail 2. One end of the connecting rod 24 extends into the round hole and is fixedly connected to the pin 21 by welding. The other end of the connecting rod 24 extends into the square hole and is fixedly provided with a lever 25 by welding. The connecting rod 24 passes through a fixing block 22 and slides with the fixing block 22. The square hole restricts the lever 25 to slide only along the length of the handrail 2. The lever 25 has an inclined surface 251 on the side near the corresponding pin 21. A button 26 is provided through and slides along the side wall of the middle section of the handrail 2 along its length. The button 26 slides along the radius of the handrail 2. The button 26 is located between the two levers 25 and simultaneously abuts against the two inclined surfaces 251. Specifically, the button 26 is rotatably provided with a first roller 261 corresponding to the inclined surface 251, and the peripheral wall of the first roller 261 abuts against the inclined surface 251.

[0034] Reference Figures 1 to 4 When it is necessary to pull the pin 21, press the button 26 inside the handrail 2. The button 26 presses the inclined surface 251 of the two levers 25. Under the guidance of the inclined surface 251, the levers 25 drive the connecting rod 24 to move away from the slide rail 11, thereby pulling the two pins 21 to simultaneously disengage from the insertion holes 111 of the slide rails on both sides. In this way, when adjusting the height of the handrail 2, no one else needs to come to the vicinity of the slide rail 11 to adjust the handrail 2. The athlete can stand on the skating machine, press the button 26, and directly adjust the height of the handrail 2, which makes it convenient for the athlete to quickly test whether the height of the handrail 2 is suitable after adjustment.

[0035] To prevent the latch 21 from disengaging due to accidental activation of button 26 by athletes during training, refer to... Figure 1 and Figure 2 A sliding sleeve 28 is fitted onto the handrail 2, and the sliding sleeve 28 slides and engages with the handrail 2 along its length. Specifically, a guide groove is formed on the side wall of the handrail 2 along its length, and a guide block is integrally formed on the inner wall of the sliding sleeve 28, which slides and engages with the guide groove along its sliding direction. A protective groove 281 is formed at the end of the sliding sleeve 28 for the button 26 to extend into. A rotating ring 29 is rotatably mounted on the outside of the handrail 2 via a bearing, and the rotating ring 29 is located on the side of the button 26 away from the sliding sleeve 28. A threaded groove 291 is formed on the side wall of the rotating ring 29 near the sliding sleeve 28, and the end of the sliding sleeve 28 can extend into the threaded groove 291 and be threadedly connected to the threaded groove 291. When the handrail 2 does not need to be adjusted during training, the sliding sleeve 28 slides to allow the button 26 to extend into the protective groove 281, and the side wall of the sliding sleeve 28 covers the button 26. Rotate the rotating ring 29 to make the end of the sliding sleeve 28 threadedly engage with the threaded groove 291, fix the position of the sliding sleeve 28, and prevent the pin 21 from dislodging due to the athlete accidentally touching the button 26 during training, thus ensuring safety during the training process.

[0036] To further reduce safety hazards during training, refer to Figure 1 A safety rope 12 is installed on the handrail 1. During training, athletes can tie the safety rope 12 to a suitable part of their body, such as the waist, or attach it to their sportswear. Even if the athlete loses balance on the ice skate, the safety rope 12 can provide additional tension to prevent them from falling, reducing safety hazards during training.

[0037] The implementation principle of the adjustable safety device for an ice skating machine according to this application embodiment is as follows: When it is necessary to adjust the height of the handrail 2 to suit the athlete's height and arm length, firstly rotate the rotating ring 29 outside the handrail 2, so that the threaded groove 291 on the side wall of the rotating ring 29 disengages from the threaded engagement with the end of the sliding sleeve 28. Then, slide the sliding sleeve 28 along the length direction of the handrail 2 to expose the button 26 in the middle of the handrail 2. Next, press the button 26 into the handrail 2. The first roller 261 on the button 26 rolls along the inclined surface 251 of the lever 25. Under the guidance of the inclined surface 251, the two levers 25 move synchronously towards the middle along the length direction of the handrail 2. The levers 25 drive the connecting rod 24 to pull the pin 21, so that the pin 21 overcomes the elastic force of the thrust spring 23 and slides into the handrail 2 until the pin 21 is completely disengaged from the insertion hole 111 on the slide rail 11. At this time, the constraint between the handrail 2 and the slide rail 11 is released. Athletes can adjust the handrail 2 to a suitable height. Once the height is determined, releasing button 26 causes the push spring 23 to return to its original shape and push the pin 21 towards the slide rail 11, allowing the pin 21 to re-insert into the corresponding hole 111 in the slide rail 11, thus fixing the height of the handrail 2. Then, the sliding sleeve 28 is slid again, causing button 26 to extend into the protective groove 281 at the end of the sliding sleeve 28. Rotating the rotating ring 29 allows the end of the sliding sleeve 28 to re-thread into the threaded groove 291, fixing the position of the sliding sleeve 28 to cover button 26 and prevent accidental activation during training. This facilitates the adjustment of the handrail 2's height to accommodate athletes of different heights and arm lengths.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
