[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-2 As shown, this utility model embodiment provides a technical solution: an ice skate, which includes a foot carrier 1, a blade holder 200, and an ice skate 300. Its detailed structure includes the following embodiments:

[0037] Example 1

[0038] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and 8 As shown, this embodiment aims to provide a detachable structure for ice skates and skate frames, which specifically includes:

[0039] The threaded mounting part 11 (metal threaded sleeve) is integrally molded with the bottom of the foot carrier 1 (which can be a shoe or an external carrier that fits onto the bottom of the shoe plate) through an injection molding process. The threaded hole is normally exposed to facilitate contact and engagement with the threaded rod 203.

[0040] The aforementioned tool holder 200 (casting process) includes a main body 201 and a connecting part 202 fixedly mounted on the main body 201. The connecting part 202 contacts the bottom of the foot carrier 1. The connecting part 202 is provided with a rotatable threaded rod 203, which can selectively screw into or out of the threaded groove mounting part 11 on the foot carrier 1, thereby realizing the connection and separation of the two.

[0041] As a further improvement to this embodiment, the knife holder 200 also includes a packing head 204, on which a T-shaped sliding block 205 is fixedly disposed. Correspondingly, the foot carrier 1 is provided with a matching groove 206 that matches the T-shaped sliding block 205 (it is wrapped by injection molding, and the matching groove 206 is also a metal part, the T-shaped sliding block 205 is also a metal part, and the matching groove 206 is located at the toe of the foot carrier 1). In the initial stage of installation, by sliding the T-shaped sliding block 205 into the matching groove 206, the knife holder 200 and the foot carrier 1 can be initially positioned and pre-connected. Then, the rear of the knife holder 200 is attached to the bottom of the foot carrier 1, and finally locked by the threaded rod 203.

[0042] Preferably, the main body and connecting parts of the blade holder 200 are made of high-quality steel to ensure that they have sufficient strength, rigidity and wear resistance to meet the harsh mechanical requirements of ice sports, and the blade holder 200 and the ice blade 300 can be integrally formed.

[0043] To facilitate the driving of the threaded rod 203, a fixing part 207 is fixedly installed inside the connecting part 202. The threaded rod 203 passes through a through hole in the center of the fixing part 207 and forms a threaded engagement with the thread inside the through hole. A first bevel gear 208 is fixedly installed on the threaded rod 203.

[0044] Furthermore, the tool holder 200 also includes a rotating part 209 distributed opposite to the tool head 204. A transmission rod 211 is rotatably mounted within this rotating part 209. The exposed end face of the transmission rod 211 is constructed as an internal hexagonal groove 210 to facilitate driving with a standard hexagonal wrench. A protrusion is also provided inside the tool holder 200, on which a second bevel gear 213 is rotatably mounted. This second bevel gear 213 is constantly meshed with the first bevel gear 208.

[0045] To ensure that the rotation of the transmission rod 211 is effectively transmitted to the second bevel gear 213, while allowing for a certain axial displacement tolerance, a polygonal prism 212 (e.g., a hexagonal prism) is fixedly mounted on the transmission rod 211. Multiple elastic arc-shaped portions 214 arranged in a circumferential array are provided within the central hole of the second bevel gear 213. The arc-shaped inner walls of these elastic arc-shaped portions 214 abut against the sides of the polygonal prism 212, thereby forming a locking mechanism to achieve a fit. When the transmission rod 211 rotates, the abutment between the polygonal prism 212 and the elastic arc-shaped portions 214 drives the second bevel gear 213 to rotate synchronously.

[0046] In this embodiment, the cross-section of the elastic arc-shaped portion 214 is a rectangular frame structure with one side being an arc-shaped surface. Preferably, the elastic arc-shaped portion 214 is made of elastic stainless steel sheet, which combines good elasticity, strength, and corrosion resistance.

[0047] And the main body 201 on one side, as Figure 5 As shown, the outer side plate 241 then covers the missing portion of the main body 201 to form the completed tool holder 200, as... Figure 4 As shown, it is fixed by bolts.

[0048] Installation process:

[0049] First, align the T-shaped sliding block 205 of the tool holder 200 with the matching slot 206 of the foot carrier 1 and slide it into place to complete the initial positioning. Then, insert a hex wrench into the internal hexagonal slot 210 at the end of the transmission rod 211 and turn the wrench. The rotation of the transmission rod 211 is transmitted to the elastic arc-shaped portion 214 of the second bevel gear 213 through the polygonal prism 212 on it, thereby driving the second bevel gear 213 to rotate. The second bevel gear 213 drives the first bevel gear 208, which meshes with it, to rotate, and the first bevel gear 208 drives the threaded rod 203 fixed to it to rotate. Since the threaded rod 203 is engaged with the through thread on the fixing part 207, the rotational motion is converted into the upward movement of the threaded rod 203, so that the end of the threaded rod 203 gradually screws into the threaded groove mounting part 11 of the foot carrier 1. As it continues to screw in, the end of the threaded rod 203 finally abuts against the bottom of the threaded groove mounting part 11, at which point the tool holder 200 is firmly locked and installed in place. During this process, the first bevel gear 208 and the second bevel gear 213 may experience slight axial separation due to the advancement of the thread, forming a predetermined gap. However, due to the design of the elastic arc-shaped part 214 and the maintenance of the meshing state of the gears (maximum gap of 4-6cm), the two always maintain effective transmission cooperation and will not experience tooth disengagement.

[0050] Disassembly process:

[0051] During disassembly, simply use a hex wrench to rotate the transmission rod 211 in the opposite direction. Through the same transmission path, drive the threaded rod 203 to rotate in the opposite direction, gradually disengaging it from the threaded groove mounting part 11. Once the threaded rod 203 is completely disengaged, the tool holder 200 can be slid out along the matching groove 206, achieving separation from the foot carrier 1.

[0052] Example 2

[0053] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, this embodiment aims to provide an ice skate with an adjustable blade tilt angle, which realizes stepless or graded adjustment of the angle between the ice skate blade and the frame (i.e., the connection part of the skate body), thereby allowing users to personalize the tilt angle of the ice skate blade, especially the heel area, according to their individual physiological characteristics or training needs.

[0054] Overall, the adjustable ice skate structure mainly includes a blade holder 200 and an ice skate 300. A headpiece 204 is fixedly provided at the end of the blade holder 200. On the end face of the headpiece 204 facing the other end of the blade holder 200, a recessed slot 400 is provided, and a hanging shaft 401 is provided in the slot.

[0055] An embedded hook portion 301 is fixedly provided on the back of the ice skate 300. During installation, the embedded hook portion 301 is inserted into the recessed slot 400 and directly suspended or hooked onto the hanging shaft 401, thereby forming a stable rotation or swing fulcrum at the front end of the ice skate 300 (near the toe side).

[0056] To achieve angle adjustment, a slanted groove 302 is provided on the back of the ice skate 300, opposite to the embedded hook portion 301. This slanted groove 302 extends at a certain angle to the length of the ice skate, and its highest point is typically near the head 204. Correspondingly, a guide slider 402 is slidably mounted on the blade holder 200. This guide slider 402 has a slanted surface that slidably engages with the slanted groove 302 on the back of the ice skate 300. By changing the forward and backward position of the guide slider 402 on the blade holder 200, the ice skate 300 can be forced to change its pitch angle around its front hook, thereby achieving flexible adjustment of the angle between the ice skate 300 and the blade holder 200 within the range of 0° to 15°.

[0057] To precisely and conveniently control the movement of the guide slider 402, the present invention further integrates a transmission adjustment mechanism. This mechanism includes a transmission rod 211 rotatably mounted on the tool holder 200, with a threaded section 2111 machined on the transmission rod 2111. The guide slider 402 has a plane facing the transmission rod 211, on which a semi-threaded toothed slide block 403 is slidably mounted. This semi-threaded toothed slide block 403 is designed to engage or disengage with the threaded section 2111 of the transmission rod 211.

[0058] More specifically, the semi-threaded toothed slide block 403 is a telescopic structure comprising a sliding fixed part that slides and engages with the guide slider 402, and a sliding sleeve that slides and engages with the sliding fixed part. The inner side of the sliding sleeve has threaded teeth that match the threaded section 2111 of the transmission rod. A groove is formed on the outer side plate 241, and the screw head of the adjusting screw 404 moves within the groove. Figure 4 As shown, an adjusting screw 404 passes through this groove and screws into the threaded hole of the semi-threaded toothed slide 403 (sliding sleeve). When the adjusting screw 404 is tightened, the screw head presses against the side of the tool holder 200, thereby locking the entire semi-threaded toothed slide 403 in place and preventing it from sliding; when loosened, its sliding ability is released.

[0059] For ease of operation, the end of the transmission rod 211 extends into a rotating part 209 fixed to the tool holder 200, and an internal hexagonal slot 210 is fixed at the end. A spring groove is formed at the bottom of the internal hexagonal slot 210, and an equidistant spring 405 is installed in the groove. The other end of the spring is connected to a ring plate 406, which forms a rotational engagement with the rotating part 209. This design allows the transmission rod 211 to move slightly against the spring force when subjected to axial thrust.

[0060] The outer side plate 241 has a groove, and the screw head of the adjusting screw 404 moves within the groove. Figure 4 As shown,

[0061] Working principle:

[0062] Insert the hex wrench into the internal hex socket 210. Gently push the wrench inward toward the tool holder 200 to move the transmission rod 211 axially inward, compressing the equidistant spring 405. This action temporarily separates the polygonal prism 212 at the front end of the transmission rod 211 from the elastic arc-shaped part 214, so as to allow for subsequent manual coarse adjustment.

[0063] Loosen the loosening screw 404 completely so that the sliding sleeve of the semi-threaded toothed slide 403 can slide freely on the plane of the guide slider 402. At this time, manually push the guide slider 402 to make a rough and quick pre-adjustment of the ice skate angle.

[0064] The sliding sleeve portion of the semi-threaded toothed slide block 403 is moved to contact and engage with the threaded section 2111 of the transmission rod 211.

[0065] Slightly tighten the loosening screw 404 to prevent the semi-threaded toothed slide 403 from sliding on its own, but not completely lock it (or completely lock it into pure thread drive mode).

[0066] At this point, rotating the hex wrench will drive the transmission rod 211 to rotate. Through the transmission of the threaded pair, the semi-threaded toothed slide 403 and the guide slide 402 connected to it will move precisely back and forth along the tool holder 200.

[0067] When the drive guide slider 402 slides close to the head of the bag 204, due to the fixed height of the guide slider 402 and the cooperation between its inclined surface and the ice blade groove 302, the end of the ice blade 300 near the heel will be forced to lift up, thereby reducing the opening angle between the ice blade 300 and the blade holder 200.

[0068] Conversely, when the drive guide slider 402 slides away from the head of the pack 204, the end of the ice skate 300 near the heel sinks downward under the assistance of gravity or external force, thereby increasing the opening angle between it and the blade holder 200.

[0069] After adjusting to the desired angle, fully tighten the loosening screw 404 to securely lock the semi-threaded toothed slide 403 and the tool holder 200, ensuring that the angle will not change during use.

[0070] It should be noted that the loosening screw 404 and the internal hex socket 210 mentioned above are operated using the same type of hex wrench. Furthermore, a marking point 600 is provided on the exposed end face of the loosening screw 404 to distinguish whether the screw 404 drives the semi-threaded toothed slide 403 to engage with the threaded section 2111.

[0071] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
