Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-collision device technology, specifically an anti-collision device for ice and snow sports building competition venues. Background Technology
[0002] Winter sports are characterized by high speed and intense competition. During competition, athletes inevitably lose control when gliding at high speeds or engaging in fierce combat, resulting in collisions with the edges of the playing area or surrounding facilities. Such collisions can cause serious injuries to athletes, such as fractures, abrasions, and concussions, greatly threatening their safety. Therefore, installing anti-collision devices on winter sports venues is essential to ensure athlete safety during competitions.
[0003] Currently, the collision avoidance measures in ice and snow sports venues are relatively simple, relying solely on basic protective barriers, which are insufficient to effectively mitigate injuries from collisions. As a result, athletes can suffer significant impacts and injuries when they collide with these barriers. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the shortcomings of the existing technology, this utility model provides a collision protection device for ice and snow sports building competition venues, which has the advantages of good buffering effect and can avoid the problem of athletes being easily injured after collision, thus solving the above-mentioned technical problems.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a collision protection device for ice and snow sports building competition venues, comprising a nylon woven mesh and a column. The nylon woven mesh is stitched with a border strip around its perimeter. A first safety hook is hooked to the edge of the border strip near the four corners, and a second safety hook is hooked to the top and bottom of the border strip. A base is fixedly connected to the bottom of the column, and a rotating shaft is rotatably connected inside the column. A limit sleeve is rotatably connected to the outer surface of the rotating shaft, and a guide wheel is fixedly connected to the outer surface of the rotating shaft. An elastic rope slides in contact with the outer surface of the guide wheel, and a binding ring is pressed to both ends of the elastic rope. A top cover is snapped onto the top of the column.
[0008] Preferably, four safety hooks are provided, and two elastic ropes are provided, with both ends of the two elastic ropes hooked to the safety hooks.
[0009] Preferably, the middle section of the elastic rope is inserted inside the second safety hook, and the elastic rope is woven from multiple strands of latex filaments.
[0010] Preferably, a straight groove is provided on one side of the column, and an elastic rope is inserted into the straight groove.
[0011] Preferably, a bearing seat is installed on the outer surface of the column, and a rotating shaft is rotatably connected inside the bearing seat.
[0012] Preferably, the column is internally rotatably connected to a vertical shaft, the outer surface of the vertical shaft is fitted with a rubber roller, and a limit pin is inserted into the top of the vertical shaft.
[0013] Compared with the prior art, this utility model provides a collision protection device for ice and snow sports building competition venues, which has the following beneficial effects:
[0014] 1. When an athlete collides with the nylon woven net, the nylon woven net shifts due to the impact force. The elastic rope, woven from multiple strands of latex filaments, stretches and deforms, absorbing some of the impact energy, reducing the impact force on the athlete, and lowering the risk of injury. At the same time, the guide wheel slides in contact with the elastic rope, and the rotating shaft can rotate inside the column. When the elastic rope is stretched or returns to its original shape, the guide wheel can guide its smooth movement, reducing the impact of friction on its cushioning performance, ensuring that the elastic rope fully exerts its elastic cushioning effect, improving the device's ability to absorb and disperse impact energy, and better protecting the athlete's safety.
[0015] 2. When the athlete collides with the column, the rubber roller on the column, due to its elasticity, can absorb part of the impact force through elastic deformation at the moment of impact, thus playing a buffering role. The limit pin at the top of the vertical shaft ensures the stability of the vertical shaft inside the column and facilitates installation, allowing the rubber roller to rotate and dissipate force after impact. The bearing seat on the outer surface of the column ensures the stable rotation of the shaft and guarantees the normal operation of related components such as guide wheels and elastic ropes during the buffering process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-4 A collision avoidance device for ice and snow sports venues includes a nylon woven mesh 1 and a column 2. The nylon woven mesh 1 is stitched with a frame strip 3 around its perimeter. The edges of the frame strip 3 are hooked with a first safety hook 4 near the four corners. The top and bottom of the frame strip 3 are hooked with a second safety hook 5. The bottom of the column 2 is fixedly connected to a base 6. The inside of the column 2 is rotatably connected to a rotating shaft 7. The outer surface of the rotating shaft 7 is rotatably connected to a limit sleeve 8. The outer surface of the rotating shaft 7 is fixedly connected to a guide wheel 9. The outer surface of the guide wheel 9 is in sliding contact with an elastic rope 10. The two ends of the elastic rope 10 are pressed with a binding ring 11. The top of the column 2 is snapped with a top cover 12.
[0023] Specifically, there are four safety hooks 4 and two elastic ropes 10. Both ends of the two elastic ropes 10 are hooked to safety hooks 4. The middle section of the elastic rope 10 is inserted into the interior of safety hook 5. The elastic rope 10 is woven from multiple strands of latex filaments. A straight groove 13 is opened on one side of the column 2, and the elastic rope 10 is inserted into the straight groove 13.
[0024] The advantages are that when an athlete collides with the nylon woven net 1, the impact force will cause the nylon woven net 1 to shift. Since the elastic rope 10 is woven from multiple strands of latex filaments and has good elasticity, it will stretch and deform under the action of the impact force, thereby absorbing part of the impact energy, effectively reducing the impact force on the athlete and reducing the risk of injury. The guide wheel 9 slides in contact with the elastic rope 10, and the rotating shaft 7 can rotate inside the column 2. When the elastic rope 10 is stretched or returns to its original shape, the guide wheel 9 can guide the elastic rope 10 to move smoothly, reducing the impact of friction on the cushioning performance of the elastic rope 10, ensuring that the elastic rope 10 can fully exert its elastic cushioning effect, further improving the device's ability to absorb and disperse impact energy, and better protecting the safety of athletes.
[0025] Specifically, a bearing seat 14 is installed on the outer surface of the column 2, a rotating shaft 7 is rotatably connected inside the bearing seat 14, a vertical shaft 15 is rotatably connected inside the column 2, a rubber roller 16 is sleeved on the outer surface of the vertical shaft 15, and a limit pin 17 is inserted into the top of the vertical shaft 15.
[0026] The advantages are that when the athlete collides with the column 2, the rubber roller 16 has a certain elasticity and can absorb part of the impact force through its own elastic deformation at the moment of impact, thus playing a buffering role. The top of the vertical shaft 15 is inserted with a limit pin 17 to ensure the relative position of the vertical shaft 15 in the column 2 is stable and to facilitate the installation of the vertical shaft 15 in the column 2. This allows the rubber roller 16 to rotate and dissipate force after being impacted. At the same time, the bearing seat 14 on the outer surface of the column 2 ensures the stable rotation of the rotating shaft 7, thereby ensuring the normal operation of components such as the guide wheel 9 and elastic rope 10 related to the rotating shaft 7 during the buffering process.
[0027] In use, firstly, connect the nylon woven mesh 1 to the elastic rope 10 via the first safety hook 4 and the second safety hook 5 on the frame strip 3, which is sewn together around the perimeter. Both ends of the two elastic ropes 10 are hooked to the first safety hook 4, and the middle section of the elastic rope 10 is inserted inside the second safety hook 5. The elastic rope 10 also passes through the straight groove 13 opened on one side of the upright 2. Fix the base 6 in a suitable position on the field to ensure the stability of the upright 2. Simultaneously, rotatably connect the vertical shaft 15 inside the upright 2, and fit a rubber roller 16 onto the outer surface of the vertical shaft 15. Insert a limiting pin 17 at the top of the vertical shaft 15, and rotatably connect the rotating shaft 7 within the bearing seat 14 on the outer surface of the upright 2. During the competition... When the athlete collides with the nylon woven net 1, the impact force causes the nylon woven net 1 to shift, causing the elastic rope 10 to stretch and deform. The elastic rope 10 absorbs part of the impact energy, and at the same time, the guide wheel 9 guides the elastic rope 10 to move smoothly, reducing the impact of friction on the cushioning performance of the elastic rope 10. If the athlete's collision direction is towards the column 2, the rubber roller 16 absorbs part of the impact force through its own elastic deformation, playing a cushioning role. At the same time, the vertical shaft 15 rotates inside the column 2 to dissipate the force, ensuring that the rubber roller 16 can work normally after being impacted. The bearing seat 14 on the outer surface of the column 2 ensures the stable rotation of the rotating shaft 7, thereby ensuring the normal operation of components such as the guide wheel 9 and elastic rope 10 related to the rotating shaft 7 during the cushioning process.
