Abstract
Description
Technical Field
[0001] This utility model relates to short track speed skating blades and belongs to the field of skating technology. Background Technology
[0002] As a competitive sport highly dependent on equipment performance, short track speed skating relies heavily on the structural design and functional adaptability of skates to directly impact an athlete's skating speed, control precision, and safety. The core technological challenges of traditional short track speed skating skates lie in three main areas: a single method of skate fixation, a conflict between shoe support strength and lightweight design, and insufficient customization options.
[0003] 1. Limitations in ice skate adjustment
[0004] Most existing ice skates use rigid fixing methods (such as bolt locking), which prevents flexible adjustment of the relative position of the skate and the skate body (especially the lateral offset). This forces athletes to rely on experience to repeatedly change skates or skate bodies to adapt to different ice surface conditions (such as hardness and temperature) or technical movements (such as the angle of inclination in corners). Although some adjustable designs allow for fine-tuning through rails or pads, they lack precise scale markings, resulting in low adjustment efficiency and a high risk of introducing errors.
[0005] 2. Bottlenecks in shoe structure performance
[0006] To balance lightweight design (often using carbon fiber composites) and torsional strength, shoe uppers, forefoot, and heels are often reinforced with localized reinforcement layers. However, traditional reinforcement designs (such as embedded metal plates) can lead to stress concentration, uneven weight distribution, and insufficient support during high-speed cornering, causing foot wobbling and affecting power transmission efficiency.
[0007] 3. Functionality expansion and maintenance deficiencies
[0008] The upper and the shoe body are mostly molded or glued together, making it impossible to quickly replace worn areas (such as replacement covers), increasing the cost of use; at the same time, the lack of modular design inside the shoe body makes it difficult to adapt to different arch shapes or customized support needs.
[0009] Therefore, there is an urgent need to develop a new type of short track speed skating blade to solve the above-mentioned technical problems. Utility Model Content
[0010] The purpose of this invention is to solve the problem of providing an ice skate that integrates high-precision adjustment, dynamic adaptive support, and modular maintenance functions. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.
[0011] The technical solution of this utility model:
[0012] A short track speed skating blade includes a boot body, a blade, a blade adjustment mount, and a fixing bolt. The blade is mounted to the bottom of the boot body via the blade adjustment mount.
[0013] The ice skate adjustment seat has an adjustment groove, and the fixing bolt passes through the adjustment groove to install the ice skate adjustment seat on the bottom of the skate body.
[0014] Preferably, the bottom of the shoe body is provided with positioning scale lines, and the ice skate adjustment seat is fixedly installed in a position determined by the positioning scale lines.
[0015] Preferably, the ice skate adjustment base is provided with a positioning mark that aligns with the positioning scale line.
[0016] Preferably, the adjustment groove is a strip-shaped hole, and the length direction of the strip-shaped hole is perpendicular to the ice blade direction of the ice blade.
[0017] Preferably, the positioning scale line is parallel to the length direction of the strip hole.
[0018] Preferably, the bottom of the shoe body has a threaded hole, and the fixing bolt passes through the adjustment groove and engages with the threaded hole.
[0019] Preferably, the upper of the shoe body is fixed by straps or zippers.
[0020] Preferably, the upper surface of the shoe body is detachably fitted with a replacement cover, a replacement instep strap, and / or a replacement ankle strap.
[0021] Preferably, the shoe body is provided with reinforcing ribs.
[0022] Preferably, the reinforcing ribs surround or partially surround the lower side of the shoe body.
[0023] Preferably, the reinforcing ribs surround or partially surround the arch or heel of the shoe.
[0024] This utility model has the following beneficial effects:
[0025] 1. The skate adjustment seat of this utility model enables the lateral position adjustment of the skate blade, allowing athletes to quickly align with the optimal skating trajectory according to the ice surface conditions (hardness, temperature) or the requirements of cornering techniques, thereby improving adjustment efficiency;
[0026] 2. The positioning scale line visualization aid of this utility model can avoid the accumulation of deviations caused by traditional "blind adjustment", and is especially suitable for emergency fine-tuning scenarios in competitions, reducing the risk of errors caused by equipment compatibility issues;
[0027] 3. The forefoot and heel of this shoe have built-in reinforcing ribs that wrap around the foot. The optimized layout forms multi-point distributed support in key stress areas (such as the metatarsals and Achilles tendons), which improves torsional strength while reducing overall weight. It avoids stress concentration caused by traditional rigid reinforcement. The composite design of the reinforcing ribs and the flexible material of the shoe lining achieves "dynamic wrapping" during high-speed cornering, improves foot fit, and reduces power transmission loss.
[0028] 4. The detachable and replaceable cover design of this utility model supports quick replacement of worn areas within 3 seconds, or switching between different hardness / breathability materials (such as carbon fiber competition version, breathable mesh training version), reducing maintenance costs and extending the fatigue life of the shoe body, which is especially suitable for high-frequency training and high-intensity competition scenarios.

[0038] Specific implementation method one: Combining Figures 1-6 This embodiment describes a short track speed skating blade, which includes a boot body 1, a blade 2, a blade adjustment seat 3, and a fixing bolt 4. The blade 2 is mounted on the bottom of the boot body 1 via the blade adjustment seat 3.
[0039] The ice skate adjustment seat 3 has an adjustment groove 5, and the fixing bolt 4 passes through the adjustment groove 5 to install the ice skate adjustment seat 3 on the bottom of the shoe body 1.
[0040] The bottom of the shoe body 1 has a threaded hole. The fixing bolt 4 passes through the adjustment groove 5 and engages with the threaded hole. By tightening or loosening the fixing bolt 4, the ice skate adjustment seat 3 can be moved laterally along the adjustment groove 5 to adjust the lateral position of the ice skate 2. The adjustment range is ±5mm.
[0041] The bottom of the shoe body 1 is provided with positioning scale lines 6, and the ice blade adjustment seat 3 is fixedly installed in a position determined by the positioning scale lines 6. The adjustment groove 5 is a strip-shaped hole, and the length direction of the strip-shaped hole is perpendicular to the ice blade direction of the ice blade 2. The positioning scale lines 6 are parallel to the length direction of the strip-shaped hole, and the direction of the scale lines is parallel to the adjustment groove 5. The interval between each scale is 1mm, and the accuracy error is ≤0.2mm.
[0042] The ice skate adjustment base 3 is provided with a positioning mark 7 that is aligned with the positioning scale line 6. The positioning mark 7 is an arrow or a scale line.
