In the prior art, the skate comprises a skate body, a skate blade and a blade holder, wherein the skate blade comprises a blade and a blade pipe, the blade is connected with the blade pipe, and the skate body is connected with the blade pipe through the blade holder. The cutter tube is a core component of the ice skate, and not only is required to bear the load caused by high-speed movement, but also is required to reduce the resistance in the movement process as much as possible, thereby reducing the influence on the athletic level of athletes. The prior art knife tube is manufactured by adopting an aluminum stamping and forging method, and due to the limitation of a processing technology, the whole knife tube must comprise a metal material with a continuous structure, particularly an aluminum alloy material, so that redundant materials and unnecessary weight are caused, and the design of the appearance of the knife tube is also limited. The weight of the knife pipe is heavy, the use is inconvenient, and the influence on the athletic level of athletes is large.

In view of this, the designer designs an ice skate blade tube, and light in weight, structural strength is high, and convenient to use is little to the sportsman's competitive level influence.

Referring to fig. 1 and 2, in the present embodiment, the ice skate blade tube includes a streamlined tube body 110, and the tube body 110 is provided with a blade slot 111 for mounting the blade 120; the pipe body 110 is provided therein with a cavity 112 independent of the knife groove 111. Since the tube 110 is provided with the cavity 112 inside, the cavity 112 is independent from the knife groove 111, i.e., the cavity 112 is a closed chamber and is not communicated with the knife groove 111. The design of the cavity 112 reduces the weight of the pipe body 110, thereby being beneficial to the use of athletes and not easily influencing the athletic level of the athletes; and the cavity 112 is designed to be closed and independent of the knife slot 111, the inner wall of the tube body 110 enclosing the cavity 112 has a continuous structure, and the structural strength of the tube body 110 is not easily affected.

In this embodiment, the tube 110 is a streamline structure, and the length of the tube 110 is set to 400mm-460 mm. The outer surface of the pipe body 110 includes a first plane and a second plane opposite to the first plane, the first plane is used for assembling the base, the second plane is provided with a knife groove 111, the knife groove 111 is a rectangular groove, and two ends of the knife groove 111 in the length direction of the pipe body 110 extend to the first end surface and the second end surface respectively.

In this embodiment, the gradient of the change in the cross-sectional area of the pipe bodyAnd G_nThe value range of (1) is (0-5.00); so, the streamlined structure of body is reasonable, and the windage is little.

Wherein S is_nRepresents the cross-sectional area of the measurement point n, (S)_n+1-S_n) Representing the difference, X, between the cross-sectional areas of adjacent measurement points_nRepresents the distance from the measuring point n to the reference line, (X)_n+1-X_n) Representing the distance between adjacent measurement points; the cross-sectional area is a cross-sectional area perpendicular to the extending direction of the pipe body 110, and the reference line is a center line in the length direction of the pipe body 110.

It will be appreciated that the tube body 110 is provided as a streamlined structure which reduces wind resistance and thereby increases speed. Further, the pipe body 110 has two transition sections, and specifically, the middle position of the length direction of the pipe body 110 is used as a boundary line to divide the pipe body 110 into a first pipe portion and a second pipe portion, and the transition sections are arranged on the first pipe portion and the second pipe portion. The transition section is a portion in which the outer profile or the cross-sectional area of the cross-section of the pipe body 110 changes depending on the position in the longitudinal direction of the pipe body 110. In the present embodiment, the cross-sectional area of the pipe body 110 is taken as an example for explanation. The cross-sectional area of the transition section is gradually increased in a direction from the middle of the pipe body 110 to the end of the pipe body 110Decreases and the gradient G of the change of the cross-sectional area of the pipe body 110 in the transition section_nIs set to be (0.03-3) mm²Mm, for example, the ratio of the cross-sectional area of the tubular body 110 increasing with distance is set to 0.03mm²/mm、1.55mm²Mm or 3mm²Mm, etc. So design, the windage of body 110 is little, and is little to sportsman's competitive level influence.

And, the length of the unilateral transition section is not less than 40mm, wherein, the length of the transition section is consistent with the length direction of the tube body 110.

To facilitate understanding of the difference between the streamline structure of the tube body of the present embodiment and the tube body of the conventional ice skate blade, please refer to fig. 6 and 7, wherein fig. 6 is a schematic structural diagram of the tube body of the present embodiment, fig. 7 is a schematic structural diagram of the tube body of the comparative example, and the data of the streamline structure of the tube body is shown in a form of a table, where table 1 is the tube body of the present embodiment, and table 2 is the tube body of the comparative example, as follows:

TABLE 1

TABLE 2

As can be seen from tables 1 and 2, the conventional pipe body is streamlined only at both ends, wherein in table 1 (X)₅-X₉) And (X-₅-X-₉) Two gradual change sections that show the body all are streamlined, and the overall structure of body is more reasonable, and the windage is little.

In this embodiment, it should be noted that the number of the cavities 112 disposed inside the tube 110 may be one or more, please refer to fig. 3, when the number of the cavities 112 is one, the cavities 112 are in a strip shape, the cavities 112 extend along the length direction of the tube 110, and the cross-sectional shape of the cavities 112 is similar to the cross-sectional outer contour shape of the tube 110, that is, as the cross-sectional outer contour of the tube 110 changes in the length direction, the cross-sectional shape of the cavities 112 also changes in the length direction of the tube 110, and the change in the cross-sectional shape of the cavities 112 is consistent with the change in the cross-sectional outer contour of the tube 110. It should be understood that two figures with equal corresponding angles and proportional corresponding sides are called similar figures, and the ratio of corresponding sides of similar figures is called similar ratio, and when the similar ratio is 1, the two similar figures are identical, and obviously, since the cavity 112 is arranged inside the tube body 110, the similar ratio of the two figures is always different from 1.

When the number of the cavities 112 is plural, the plural cavities 112 are arranged at intervals in the length direction of the tube body 110, and the center lines of the plural cavities 112 are collinear with the center line of the tube body 110. And, the cross-sectional shape of each cavity 112 is similar to the cross-sectional outer contour shape of the tube body 110.

In this embodiment, the cross-sectional shape of the cavity 112 is similar to the cross-sectional outer contour shape of the tube 110, so that the tube 110 is stressed more uniformly, has high structural strength, and is not easily damaged.

In this embodiment, the cross-sectional shape of the cavity 112 may be one or a combination of at least two of a circle, an ellipse, a drop, a polygon and a curve, wherein the cross-section is a plane perpendicular to the length direction of the tube body 110. Meanwhile, the range of the cross-sectional area of the cavity 112 is set to 0mm²-190 mm²It is apparent that the cross-sectional area of the cavity 112 is not 0.

Referring to fig. 2, in order to improve the structural strength and safety of the tube 110, a rib structure 130 is disposed in the cavity 112 and outside the tube. For example, the rib structures 130 may be disposed in the cavity 112, and the rib structures 130 are connected to the inner wall surface of the tube body forming the cavity, and the rib structures 130 disposed in the cavity may be configured as a honeycomb structure, a rectangular array structure, or an annular array structure. The stiffener structure located outside the tube body may be welded or integrally formed with the tube body, and the stiffener structure 130 located outside the tube body may be provided as a geometric support structure. By providing the rib structure 130, the structural strength of the pipe body 110 can be enhanced. Meanwhile, the inner and outer reinforcing rib structures 130 and the pipe body 110 can be integrated, for example, the reinforcing rib structures 130 can be integrated with the pipe body 110 in a welding manner, or the reinforcing rib structures 130 can be integrated with the pipe body 110 in a 3D printing manner, so that the reinforcing rib structures 130 and the pipe body 110 are combined more closely, and the strength enhancement effect on the pipe body 110 is better.
