Description

Technical Field

[0001] This utility model relates to the field of ski technology, and in particular to a double ski with strong grip. Background Technology

[0002] With economic development, skiing has become increasingly popular; skis can be designed in different styles to meet various needs.

[0003] Current skis rely on metal edges for turning and braking grip, but in hard snow, ice, or steep slopes, the contact area between the edges and the snow is limited, making it easy to slip and lose control. Adding textures or embedding spikes to the bottom would disrupt the smoothness of the ride and would not be able to open and close as needed, failing to meet higher usage requirements. Therefore, improvements are necessary. Utility Model Content

[0004] This invention provides a high-grip double ski that can increase grip when turning or braking without affecting the smoothness of skiing, thus meeting higher usage requirements. It solves the technical problems of existing skis having a simple structure, poor grip in some situations, and being prone to loss of control and slipping, while other anti-slip structures can disrupt the smoothness of skiing and fail to meet higher processing and usage requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a double-sided ski with strong grip, comprising a ski body, wherein a grip triggering structure is provided at the deformation point of the bottom of the ski, the grip triggering structure is triggered when turning or braking, and automatically resets after the turn; the grip triggering structure includes a plurality of grip teeth rotatably embedded in the bottom of the ski, and a linkage structure that cooperates with the grip teeth is hidden inside the ski. When in a straight-line skiing state, the grip teeth are hidden inside the ski; when turning or braking, the ski will deform, and depending on the situation, the front end, rear end and foot of the ski will have different deformations. During deformation, the linkage structure will drive the grip teeth to pop out quickly, the grip teeth will penetrate the snow to form anchor points, increasing the grip and stability of the ski; after turning or braking, the grip teeth will reset.

[0006] Preferably, the ski has a deformation cavity at its bottom, and a rotating shaft is rotatably mounted on one side of the deformation cavity, with traction teeth fixed at intervals on the rotating shaft. The ski in this invention has a multi-layer structure, which ensures the strength and elasticity of the ski. The traction teeth are hidden inside the deformation cavity, and the traction teeth are controlled by the rotating shaft and a linkage structure.

[0007] Preferably, the rotating shaft has an integrally formed fan-shaped toothed groove that mates with the linkage structure. The rotating shaft, through the fan-shaped toothed groove and its engagement with the linkage structure, controls the rotation angle of the gripping teeth.

[0008] Preferably, the linkage structure includes a push rod fixed at the deformation point of the ski within the deformation cavity. A rack is integrally formed on the surface of the push rod, and a connecting gear is provided on one side of the push rod, meshing with the rack on the push rod surface. When the ski deforms, a relative displacement occurs between the push rod and the connecting gear. The push rod drives the connecting gear to rotate, which in turn drives the rotating shaft to rotate. The gripping teeth quickly eject from the snow scraper grooves, embedding themselves into the snow to form anchor points, increasing the ski's grip and stability.

[0009] Preferably, the adapter gear meshes with the fan-shaped tooth grooves on the surface of the rotating shaft.

[0010] Preferably, the transmission structure consisting of the adapter gear, shaft, and push rod has an output speed greater than the input speed. This ensures that the gripping gears can quickly eject during deformation.

[0011] Preferably, the grip plates are made of titanium alloy. Titanium alloy grip plates have high strength and good cold resistance, making them suitable for use in snowy environments.

[0012] Preferably, the rotation angle of the grip pegs is between 0 and 60 degrees. However, due to limitations imposed by ski deformation, the rotation angle of the grip pegs is also restricted.

[0013] Preferably, the end of the grip teeth is integrally formed with a barb structure. The barb structure at the end of the grip teeth can increase traction when in contact with snow.

[0014] Preferably, the bottom of the skis has several snow-scraping grooves spaced apart, corresponding to the grip teeth. After turning or braking, the push rod and grip teeth return to their original positions, and the snow-scraping grooves scrape away the snow from the surface of the grip teeth.

[0015] Therefore, the dual-plate ski with strong grip of this utility model has the following advantages: it can increase grip when the ski is turning or braking, without affecting the smoothness of the ski's normal gliding, and can meet higher usage requirements. Attached Figure Description

[0022] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: like Figure 1 and 2 As shown in Figures 3, 4, and 5, a dual-plate ski with strong grip includes a ski body 1. The ski body 1 has a layered structure, with the top layer being a carbon fiber layer and the bottom layer being a highly elastic layer made of polyurethane and glass fiber. A grip triggering structure is installed at the deformation point at the bottom of the ski body 1. The grip triggering structure is triggered when turning and automatically resets after turning.

[0024] The grip triggering structure includes a deformation cavity 2 located at the front, rear, and middle deformation points of the ski. A rotating shaft 3 is rotatably installed on one side of the deformation cavity 2. A fan-shaped toothed groove 4 is integrally formed on the right side of the rotating shaft 3. Several gripping toothed plates 5 are fixed at intervals on the left side of the rotating shaft 3.

[0025] The bottom of the deformation cavity 2 is provided with several snow scraping grooves 6 that correspond to the gripping toothed plates 5.

[0026] The rotation angle of the grip paddle 5 is between 0 and 60 degrees.

[0027] The grip teeth 5 are made of titanium alloy.

[0028] The 5-piece gripper has a one-piece molded tail end with a barbed structure.

[0029] The deformation cavity 2 is equipped with a linkage structure that cooperates with the gripping tooth 5; the linkage structure includes a push rod 7 fixed in the deformation cavity 2 at the deformation point of the ski, the surface of the push rod 7 is integrally formed with a rack, and a transition gear 8 is rotatably installed on the left side of the push rod 7. The transition gear 8 meshes with the rack on the surface of the push rod 7 and meshes with the fan-shaped tooth groove 4 on the surface of the rotating shaft 3.

[0030] The transmission structure consisting of the adapter gear 8, the rotating shaft 3, and the push rod 7 has an output speed greater than the input speed.

[0031] When skiing in a straight line, the grip teeth 5 are hidden in the deformation cavity 2. When turning or braking, the skis will deform. Depending on the situation, the front end, tail end and foot of the skis will deform differently. During deformation, the push rod 7 and the adapter gear 8 will have relative displacement. The push rod 7 drives the adapter gear 8 to rotate, and the adapter gear 8 will drive the shaft 3 to rotate. Since the output speed is greater than the input speed, the grip teeth 5 will quickly pop out from the snow scraper 6. The grip teeth 5 will penetrate the snow to form anchor points, increasing the grip and stability of the skis.

[0032] After turning or braking, the push rod 7 and the grip 5 return to their original positions, and the snow scraper 6 scrapes away the snow from the surface of the grip 5.

[0033] The specific embodiments described herein are merely illustrative examples of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.
