Description

Technical Field

[0001] This invention relates to the field of sports equipment technology, specifically to a lacrosse stick. Background Technology

[0002] Lacrosse, as a competitive sport, places extremely high demands on the performance of the clubs. They need to be strong enough to cope with intense competition, and lightweight to improve the athlete's control, flexibility, and swing speed.

[0003] In some applications, weight reduction in golf clubs is achieved by thinning the overall wall thickness or replacing materials with lighter ones. However, these existing techniques have several problems. Firstly, thinning the overall wall thickness weakens the club's impact resistance, making it prone to deformation or breakage during intense play, thus affecting the club's lifespan and the player's experience. Secondly, while using high-end lightweight materials can achieve weight reduction, it significantly increases manufacturing costs, limiting its widespread application. Furthermore, both wall thinning and material replacement employ uniform weight reduction methods, failing to optimize the design for different usage areas of the club (such as the striking area and grip area), resulting in an unreasonable weight distribution and failing to fully realize the advantages of weight reduction.

[0004] Therefore, this application studies a lacrosse stick that optimizes weight distribution, ensures the overall strength of the stick, and achieves lightweighting while improving maneuverability. Utility Model Content

[0005] In order to optimize the weight distribution, ensure the overall strength of the hockey stick, achieve lightweighting and improve handling flexibility, this application provides a lacrosse stick.

[0006] This application provides a lacrosse stick, which adopts the following technical solution: A lacrosse stick includes a stick body, wherein a first weight-reducing structure is provided between 20-39cm of the end near the end of the stick body, and a second weight-reducing structure is provided between 0-15cm. Both the first weight-reducing structure and the second weight-reducing structure are grooves formed on the inner wall of the stick body.

[0007] By adopting the above technical solution, and by setting inner wall grooves in specific areas of the cue as a weight-reducing structure, the cue is made lighter, and the strength reduction problem caused by overall wall thickness reduction is avoided. At the same time, the optimized design for different usage areas improves the rationality of weight reduction distribution and solves the problem that it is difficult to balance weight reduction and strength in the existing technology.

[0008] Optionally, the groove depth is 30%-50% of the wall thickness of the cue stick body, and the groove width is 3-6mm.

[0009] By adopting the above technical solutions, it is ensured that the weight reduction structure does not excessively weaken the wall thickness of the club body while achieving weight reduction, thereby ensuring the overall strength and impact resistance of the club and further optimizing the balance between weight reduction and strength.

[0010] Optionally, the groove of the first weight-reducing structure is a plurality of first annular grooves spaced apart along the length direction of the cue body.

[0011] By adopting the above technical solution, the weight of the club tail can be distributed more evenly, further optimizing the weight reduction effect, while maintaining the structural integrity of the club tail and avoiding insufficient strength due to excessive local weight reduction.

[0012] Optionally, five annular grooves are evenly spaced, and the distance between adjacent annular grooves is 1.4 mm.

[0013] By adopting the above technical solutions, we can ensure that while reducing weight, we can effectively avoid stress concentration and guarantee the stability and impact resistance of the club tail during the swing.

[0014] Optionally, the groove of the second weight-reducing structure has multiple second annular grooves spaced apart along the length direction of the cue body.

[0015] By adopting the above technical solutions, the weight distribution of the grip area can be optimized, reducing the weight felt when gripping, without affecting the structural strength of the grip area, thus improving the athlete's maneuverability and comfort.

[0016] Optionally, five annular grooves are evenly spaced, and the distance between adjacent annular grooves is 1.4 mm.

[0017] By adopting the above technical solution, the structural strength and feel of the grip area are not affected by the excessive density of the weight reduction structure, thus ensuring that athletes can have a better control experience when gripping the object.

[0018] Optionally, both ends of the groove in the cross-section of the cue body are U-shaped, V-shaped, or arc-shaped structures.

[0019] By adopting the above technical solutions, the selection can be optimized according to the specific usage requirements and mechanical performance requirements of the cue, further improving the mechanical performance and applicability of the weight-reducing structure and enhancing the overall performance of the cue.

[0020] Optionally, the cue body may be made of carbon fiber, aluminum alloy, or composite materials.

[0021] By adopting the above technical solutions, the overall weight of the cue can be further reduced while ensuring its strength. At the same time, these materials have good corrosion resistance and durability, which improves the service life and performance stability of the cue.

[0022] Optionally, both the first weight-reducing structure and the second weight-reducing structure are manufactured by in-mold forming or CNC machining.

[0023] By adopting the above technical solutions, the processing accuracy and surface quality of the weight-reducing structure can be ensured, stress concentration caused by processing defects can be avoided, and production efficiency and product quality consistency can be improved, while reducing production costs.

[0024] In summary, this application includes the following beneficial technical effects: 1. By setting inner wall grooves in specific areas of the cue as a weight-reducing structure, the cue is made lighter and the strength reduction problem caused by overall wall thickness reduction is avoided. At the same time, the optimized design for different use areas improves the rationality of weight reduction distribution and solves the problem of difficulty in balancing weight reduction and strength in the existing technology. 2. The distribution of the first and second annular grooves can more evenly distribute the weight of the club tail, further optimizing the weight reduction effect, while maintaining the structural integrity of the club tail and avoiding insufficient strength due to excessive local weight reduction; 3. The depth and width of the grooves ensure that the weight-reducing structure does not excessively weaken the wall thickness of the club body while achieving weight reduction, thereby ensuring the overall strength and impact resistance of the club and further optimizing the balance between weight reduction and strength.
