Description

Technical Field

[0001] This utility model belongs to the field of snowboard technology, and in particular relates to a fall protection device for snowboards. Background Technology

[0002] Snowboards are the core equipment used in skiing for gliding on snow. They enable high-speed gliding, turning, and braking through friction with the snow surface and control of the rider's center of gravity.

[0003] For example, Chinese patent CN221491408U discloses a ski, including a ski body with a mounting groove that runs through the ski body. A flip frame is hinged in the mounting groove and extends along the length of the mounting groove. A rotatable rolling shaft is provided in the flip frame, and a positioning mechanism is provided on the flip frame to fix the flip frame in place. An environmental acquisition component, including a GPS positioning sensor, is provided in the ski body. The flip frame drives the rolling shaft to flip to the bottom of the ski body. By lifting one end of the ski body by hand, the rolling shaft on the other end of the ski body touches the ground, and the entire ski body is moved by dragging. This achieves the convenience of carrying the ski and solves the problem of excessive weight in snowboards. The GPS positioning sensor can also locate the position of the ski. The ski body can collect data on the user's current skiing situation and conduct risk assessments through the environmental acquisition component.

[0004] The aforementioned patent has the following problems: This patented design has some drawbacks in use, such as the lack of a fall-prevention mechanism on the skis. Beginners or children using these skis to learn to ski may lose their balance and fall. Therefore, we propose a fall-prevention device for snow skis. Utility Model Content

[0005] The purpose of this invention is to provide a fall protection device for snow skis to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a fall protection device for snow skis, including snow skis, and further comprising: Two housings are fixedly connected to the top surface of the ski. Two first sliding grooves are opened inside each housing. Two sliding rods are slidably connected in each of the two first sliding grooves. A clamping block is fixedly connected to one end of each sliding rod. A threaded rod is threadedly connected to the sliding rod. Two drive components are located in two housings respectively and are used to drive the corresponding two slide rods to move. Two second sliding grooves are respectively opened on the top surface of the two shells. Two support rods are slidably connected in the second sliding grooves. One of the support rods is internally threaded with a bolt, and the bottom end of the bolt is fixedly connected with a pressing block. Two transmission components are located in two housings respectively and are used to drive two support rods to move.

[0007] Based on the above structure, the first slide groove and slide rod ensure that the slide rod can move along the first slide groove. The drive assembly and threaded rod ensure that the user can drive the two threaded rods to rotate in opposite directions, so that the two slide rods are acted upon by the threads of the two threaded rods, moving away from or towards each other. The clamping blocks ensure that when the two slide rods approach each other, they will each drive the two clamping blocks to approach each other, clamping them onto the ski. The housing is then fixed in place. The second slide groove, support rods, and transmission assembly ensure that the two support rods can move along the second slide groove. When one support rod moves, it will drive the other support rod to move simultaneously through the transmission assembly, allowing the user to adjust the distance between the two support rods. The bolt and clamping block ensure that when the user rotates the bolt, the bolt will be acted upon by the threads of one of the support rods, causing the clamping block to move downwards and press against the inner wall of the second slide groove, fixing one of the support rods within the second slide groove and preventing it from moving.

[0008] In the above technical solution, the driving component further includes: A gear groove is formed inside the housing and communicates with two first sliding grooves. Two first bevel gears are rotatably connected inside the gear groove, and one end of each of the two first bevel gears extends into the two first sliding grooves and is fixedly connected to one end of each of the two threaded rods. A second bevel gear meshes between the two first bevel gears. A rotating rod is fixedly connected to the second bevel gear, and one end of the rotating rod passes through the inner wall of the gear groove and extends to the outside and is rotatably connected to the housing. A fixing component is located on the periphery of the rotating rod and is used to fix the rotating rod.

[0009] This technical solution ensures that users can remove the drop protection device when it is no longer needed.

[0010] In the above technical solution, the fixing component further includes: A threaded groove is formed on the circumference of the rotating rod, and a threaded sleeve is threadedly connected inside the threaded groove.

[0011] In this technical solution, it is ensured that the rotating rod will not be affected by external factors and will not rotate.

[0012] In the above technical solution, one end of the first bevel gear is rotatably connected to the first sliding groove.

[0013] In this technical solution, it is ensured that when the first bevel gear rotates, one end of the first bevel gear can rotate normally within the first slide groove.

[0014] In the above technical solution, the transmission component further includes: The movable groove is formed inside the housing and communicates with the second sliding groove. Two racks are slidably connected in the movable groove, and the top ends of the two racks extend into the second sliding groove and are fixed to the bottom surfaces of the two support rods respectively. Gears mesh between the two racks.

[0015] In this technical solution, the user can adjust the spacing between the two support rods to adjust the support capacity of the skis.

[0016] In the above technical solution, furthermore, the top ends of the two racks are slidably connected to the second groove.

[0017] In this technical solution, it is ensured that when the two racks move, the tops of the two racks can slide normally within the second groove.

[0018] In the above technical solution, the gear is further located in the movable groove and rotatably connected to the movable groove.

[0019] In this technical solution, it is ensured that the gear can rotate normally within the movable slot when it rotates.

[0020] In the above technical solution, furthermore, the threads on the multiple threaded rods have the same direction of rotation.

[0021] In this technical solution, it is ensured that when the corresponding two threaded rods rotate in opposite directions, the two slide rods will be acted upon by the threads of the two threaded rods respectively, and will move away from or towards each other along the two first slide grooves respectively.

[0022] The beneficial effects of this utility model are: 1. This snowboard anti-fall device, through the setting of a first slide groove and slide bar, ensures that the slide bar can move along the first slide groove. Through the setting of a drive component and threaded rod, it ensures that the user can drive the two threaded rods to rotate in opposite directions through the drive component, so that the two slide bars are acted upon by the threads of the two threaded rods, moving away from or closer to each other. Through the setting of a clamping block, it ensures that when the two slide bars are close to each other, the two slide bars will each drive the two clamping blocks to move closer to each other, clamping them onto the snowboard and fixing the shell. Through the setting of a second slide groove, support rod, and transmission component, it ensures that the two support rods can move along the second slide groove. When one support rod moves, it will drive the other support rod to move simultaneously through the transmission component, allowing the user to adjust the distance between the two support rods. Through the setting of a bolt and a pressing block, it ensures that when the user turns the bolt, the bolt will be acted upon by the thread of one of the support rods, causing the pressing block to move downward and press against the inner wall of the second slide groove, fixing one of the support rods in the second slide groove and preventing it from moving. This solves the problem that beginners or children may lose their balance and fall when using snowboards to learn to ski.

[0023] 2. The snow ski uses a fall protection device. Through the setting of fixed components, it is ensured that the user can fix the swivel bar in the shell and prevent it from rotating due to external influences. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0027] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0028] Example 1: This example provides a fall protection device for snowboards, including a snowboard 1, and further comprising: Two housings 2 are fixedly connected to the top surface of the ski 1. Two first sliding grooves 3 are opened inside the housings 2. Two sliding rods 4 are slidably connected in the two first sliding grooves 3 respectively. One end of each sliding rod 4 is fixedly connected to a clamping block 5. A threaded rod 6 is threadedly connected inside the sliding rod 4. Two drive components are located in two housings 2 respectively, and are used to drive the corresponding two slide rods 4 to move. Two second sliding grooves 7 are respectively opened on the top surface of the two housings 2. Two support rods 8 are slidably connected in the second sliding grooves 7. One of the support rods 8 is threaded with a bolt 9. The bottom end of the bolt 9 is fixedly connected with a pressing block 10. Two transmission components are located in two housings 2 respectively, and are used to drive two support rods 8 to move.

[0029] Example 2: This example provides a fall protection device for snowboards. In addition to the technical solutions of the above examples, it also has the following technical features, including a drive component: Gear groove 11 is formed inside the housing 2 and communicates with two first sliding grooves 3. Two first bevel gears 12 are rotatably connected inside the gear groove 11, and one end of each of the two first bevel gears 12 extends into the two first sliding grooves 3 and is fixedly connected to one end of each of the two threaded rods 6. A second bevel gear 13 meshes between the two first bevel gears 12. A rotating rod 14 is fixedly connected to the second bevel gear 13, and one end of the rotating rod 14 passes through the inner wall of the gear groove 11 and extends to the outside and is rotatably connected to the housing 2. A fixing component is located on the periphery of the rotating rod 14 and is used to fix the rotating rod 14.

[0030] In use, the user manually rotates the rotating rod 14, causing the second bevel gear 13 to rotate within the gear groove 11. This causes the rotating rod 14 to rotate the two first bevel gears 12 in opposite directions. When the two first bevel gears 12 rotate in opposite directions, they will each drive the two threaded rods 6 to rotate in opposite directions. When the two threaded rods 6 rotate in opposite directions, the two sliding rods 4 will be acted upon by the threads of the two threaded rods 6, moving away from or towards each other along the two first sliding grooves 3. When the two sliding rods 4 move away from each other, they will each drive the two clamping blocks 5 to move away from each other. At this point, the fixing of the housing 2 is released, ensuring that the user can remove the anti-fall device when it is not needed.

[0031] Example 3: This example provides a fall protection device for snowboards. In addition to the technical solutions of the above examples, it also has the following technical features, including a fixing component: The threaded groove 15 is formed on the circumference of the rotating rod 14, and the threaded groove 15 is threadedly connected to the threaded sleeve 16.

[0032] In use, the user rotates the threaded sleeve 16 by hand, causing the threaded sleeve 16 to move towards the housing 2 under the action of the threaded groove 15, so that the threaded sleeve 16 is tightly pressed against the top surface of the housing 2, fixing the rotating rod 14 inside the housing 2 and preventing it from rotating.

[0033] Example 4: This example provides a fall protection device for snow skis. In addition to the technical solutions of the above examples, it also has the following technical features: one end of the first bevel gear 12 is rotatably connected to the first groove 3.

[0034] Specifically, it is ensured that when the first bevel gear 12 rotates, one end of the first bevel gear 12 can rotate normally within the first slide groove 3.

[0035] Example 5: This example provides a fall protection device for snowboards. In addition to the technical solutions of the above examples, it also has the following technical features: the transmission component includes: The movable groove 17 is opened inside the housing 2 and communicates with the second slide groove 7. Two racks 18 are slidably connected inside the movable groove 17, and the top ends of the two racks 18 extend into the second slide groove 7 and are fixed to the bottom surfaces of the two support rods 8 respectively. Gears 19 mesh between the two racks 18.

[0036] In operation, the user slides one of the support rods 8, causing it to move one of the racks 18 within the movable groove 17. This causes the rack 18 to move via the gear 19, bringing the two racks 18 closer together or further apart. As the other rack 18 moves, it moves the other support rod 8, again bringing them closer together or further apart. When the two support rods are at a suitable distance, the user rotates the bolt 9. The bolt 9, acting on the thread of one of the support rods 8, moves the pressing block 10 downwards, pressing it tightly against the inner wall of the second slide groove 7. This fixes one support rod 8 within the second slide groove 7, simultaneously fixing the other support rod 8 within the second slide groove 7, preventing it from moving. This allows the user to adjust the distance between the two support rods 8 to regulate the support capacity of the ski 1.

[0037] Example 6: This example provides a fall protection device for snow skis. In addition to the technical solutions of the above examples, it also has the following technical features: the top ends of the two racks 18 are slidably connected to the second groove 7.

[0038] Specifically, it is ensured that when the two racks 18 move, the tops of the two racks 18 can slide normally within the second groove 7.

[0039] Example 7: This example provides a fall protection device for snow skis. In addition to the technical solutions of the above examples, it also has the following technical features: the gear 19 is located in the movable groove 17 and is rotatably connected to the movable groove 17.

[0040] Specifically, it is ensured that when gear 19 rotates, gear 19 can rotate normally within the movable groove 17.

[0041] Example 8: This example provides a fall protection device for snow skis. In addition to the technical solutions of the above examples, it also has the following technical features: the threads on the multiple threaded rods 6 have the same direction of rotation.

[0042] Specifically, when the corresponding two threaded rods 6 rotate in opposite directions, the two slide rods 4 will be acted upon by the threads of the two threaded rods 6 respectively, moving away from or towards each other along the two first slide grooves 3.

[0043] Working principle: In use, the user slides one of the support rods 8 by hand, causing one of the support rods 8 to move one of the racks 18 within the movable groove 17. This causes one rack 18 to move another rack 18 via the gear 19, bringing the two racks 18 closer together or further apart. When the other rack 18 moves, it moves the other support rod 8, bringing the two support rods 8 closer together or further apart. When the two support rods 8 are far apart to a suitable position, the user rotates the bolt 9 by hand. The bolt 9 is then acted upon by the thread on one of the support rods 8, causing the pressing block 10 to move downwards. This causes the pressing block 10 to press tightly against the inner wall of the second slide groove 7, fixing one of the support rods 8 within the second slide groove 7. At the same time, the other support rod 8 is also fixed within the second slide groove 7 and cannot move, ensuring that the user can adjust the distance between the two support rods 8 to adjust the support capacity of the ski 1. In use, the user manually rotates the rotating rod 14, causing the rotating rod 14 to drive the second bevel gear 13 to rotate within the gear groove 11. This causes the rotating rod 14 to drive the two first bevel gears 12 to rotate in opposite directions. When the two first bevel gears 12 rotate in opposite directions, they will drive the two threaded rods 6 to rotate in opposite directions. When the two threaded rods 6 rotate in opposite directions, the two sliding rods 4 will be acted upon by the threads of the two threaded rods 6, moving away from or towards each other along the two first sliding grooves 3. When the two sliding rods 4 move away from each other, they will drive the two clamping blocks 5 to move away from each other. At this point, the fixing of the housing 2 is released, ensuring that the user can remove the anti-drop device when it is not needed. When in use, the user rotates the threaded sleeve 16 by hand, so that the threaded sleeve 16 is subjected to the action of the threaded groove 15 and moves towards the housing 2, so that the threaded sleeve 16 is tightly pressed against the top surface of the housing 2, fixing the rotating rod 14 inside the housing 2 and preventing it from rotating.
