Description

Technical Field

[0001] This invention relates to the field of ice skate technology, and in particular to a quick ice skate changing structure. Background Technology

[0002] Sports are an important part of national fitness, and ice skating is one of the main ice sports. Athletes showcase the beauty and charm of sports with their superb skills and graceful movements, adding a dazzling brilliance to the sport.

[0003] Ice skates need to be replaced promptly if they develop chips or have been used for an extended period. Otherwise, it's very dangerous to be unable to exert force while skating, making falls more likely. Changing ice skate blades is currently quite cumbersome. In emergencies (such as during competitions) where a quick blade change is needed, the inability to quickly install the blades onto the skate's frame hinders the efficiency of the change, sometimes causing even greater problems. Furthermore, most users change blades with one hand, and current technology often makes one-handed operation difficult and fast. Additionally, the blade-changing mechanism is frequently exposed, making it easy to accidentally lock the skate during intense skating, posing a significant safety hazard.

[0004] Therefore, the existing ice skate replacement mechanism needs further improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a quick and safe ice skate replacement structure that is simple in structure, easy to replace, fast and safe.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A quick-change ice skate structure includes: a blade holder having a front support shell, a rear support shell, and a mounting groove communicating with the lower part of the front and rear support shells for mounting the blade; a limiting part disposed at the rear end of the mounting groove for fixing the rear end of the blade; a rotating hook hinged within the front support shell for fixing the front end of the blade; at least one elastic clamping device disposed within the front support shell for keeping the rotating hook locked to the blade; an unlocking component disposed within the front support shell, one end of which presses against the upper rear side of the rotating hook to disengage it from the blade, and the other end extends out through the outside of the front support shell; and a safety component disposed on the front support shell and connected to the unlocking component for restricting the movement of the unlocking component.

[0008] Furthermore, it also includes a quick ejection device, which includes a guide groove with an opening at the bottom inside the front support shell. An ejection cylinder and a first spring that keep the ejection cylinder bouncing downwards slide up and down in the guide groove. The lower end of the ejection cylinder abuts against the upper side of the front end of the blade.

[0009] Furthermore, the limiting part includes a through hole that extends through the rear end of the mounting groove, and a fixing shaft that engages with the U-shaped groove at the rear end of the blade is inserted into the through hole.

[0010] Furthermore, the fixed shaft is a rivet.

[0011] Furthermore, the elastic clamping device is a torsion spring, which is sleeved on the hinge shaft of the rotating hook.

[0012] Furthermore, an anti-rotation block is provided at the upper end of the rotating hook.

[0013] Furthermore, the unlocking component includes a limiting groove disposed within the front support shell, a driving top block that slides back and forth within the limiting groove, the front end of the driving top block abutting against the rear side of the anti-rotation block, and an unlocking crossbar that slides back and forth on the rear side of the front support shell, the front end of the unlocking crossbar abutting against the rear end of the driving top block.

[0014] Furthermore, the rear end of the unlocking crossbar extends to the rear side of the front support shell and is provided with a push button. A push button placement groove is provided on the outside of the front support shell, and the push button is movably disposed in the push button placement groove.

[0015] Furthermore, the safety component includes a track groove disposed on the upper end of the push button, a safety catch block that slides up and down in the track groove, a limiting notch on the upper side of the push button placement slot, and a second spring connected between the track groove and the safety catch block to keep the safety catch block extended into the limiting notch.

[0016] Furthermore, a third spring is connected between the front end of the drive top block and the inner wall of the front support shell.

[0017] In summary, the advantages of this invention over the prior art are:

[0018] The quick-change ice skate structure of this invention has advantages over existing technologies in that it is simple in structure and allows for convenient and quick replacement of the ice skate. During replacement, firstly, the safety catch is pressed to disengage from the limiting notch. Then, the safety catch and the push button are moved together into the push button placement slot. The unlocking crossbar then pushes the anti-rotation block, causing the rotating hook to rotate and disengage from the fixed hook. Finally, the ejector cylinder ejects the blade. The ice skate can be quickly disassembled with one hand. During installation, simply align the pressing part of the blade with the limiting part, rotate the ice skate, insert the fixed hook into the front support shell, and lock it by rotating the hook. The simple operation allows for quick ice skate replacement, significantly reducing replacement time. Furthermore, the safety mechanism prevents accidental contact with the unlocking crossbar, ensuring user safety. Additionally, the rotating hook is made of zinc alloy, which strengthens the blade's fixing strength, ensuring normal product use and enhancing practicality. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1 to 5The illustrated quick-change ice skate structure includes a skate holder 1, which has a front support shell 3 corresponding to the forefoot position and a rear support shell 4 located at the heel position, as well as a mounting groove 5 formed below the front and rear support shells 3 and 4 and communicating with them for mounting a blade 2 (the blade 2 refers to a traditional ice skate); a limiting part 6 for fixing the rear end of the blade 2, the limiting part 6 being located within the mounting groove 5 at the heel position; a rotating hook 62 for fixing the front end of the blade 2, the rotating hook 62 being hinged within the front support shell 3; the bottom of the rotating hook 62 has a hook that can cooperate with the hook body on the ice skate, and above the hinge axis has a protruding part, namely an anti-spin block 63; the overall cross-section of the rotating hook 62 viewed from front to back is cross-shaped (see [reference]). Figure 4 At least one elastic clamping device 64 is used to keep the rotating hook 62 locked to the blade 2. The elastic clamping device 64 is disposed inside the front support shell 3. The unlocking component 7 is disposed inside the front support shell 3. One end of the unlocking component 7 presses against the rear side of the anti-rotation block 63 protruding from the upper end of the hinge shaft of the cross-shaped rotating hook 62 to press the rotating hook 62 so that it can be released from the blade 2. The other end extends and passes through the outer side of the wall of the front support shell 3. The extension direction of the unlocking component 7 is consistent with the length direction of the ice skate. The safety component 9 is used to restrict the movement of the unlocking component 7. The safety component 9 is disposed on the front support shell 3 and slidably connected to the unlocking component 7. When the safety component is locked, a part of its body will be in close contact with the outer wall of the front support shell 3. After unlocking, it will be released from the outer wall of the front support shell 3.

[0028] like Figures 2 to 4 As shown in the figure, the present invention also includes a quick ejection device for ejecting the blade 2. The quick ejection device includes a guide groove 91 with an opening at the bottom, which is disposed in the front support shell 3. An ejection cylinder 92 and a first spring 93 that keep the ejection cylinder 92 moving downward slide in the guide groove 91. The lower end of the ejection cylinder 92 abuts against the upper side of the front end of the blade 2. When the rotating hook 62 disengages from the fixing hook 10 on the blade, the ejection cylinder 92 is ejected by the elastic force of the second spring 93, thereby ejecting the front end of the blade 2 out of the mounting groove 5, which facilitates the removal of the blade 2 and improves the efficiency of blade replacement.

[0029] See Figures 2 to 3As shown, the limiting part 6 includes a through hole 21 that passes through the rear end of the mounting groove 5 (i.e., the position corresponding to the lower part of the rear support shell 4). A fixing shaft 22 that can cooperate with the U-shaped groove 11 at the rear end of the blade 2 is inserted into the through hole 21. The fixing shaft 22 is preferably a rivet. The fixing shaft 22 is installed by riveting, which is simple in structure and easy to install. The rear U-shaped groove 11 of the blade 2 is obliquely inserted into the fixing shaft 22 in the mounting groove 5. The front end of the blade 2 is flipped and pressed to insert it into the mounting groove 5. Then, the bottom hook of the rotating hook 62 is squeezed, causing the rotating hook 62 to flip. The front end of the blade 2 is pressed to make the hook body on the blade body pass over the bottom hook of the rotating hook 62. At this time, the rotating hook 62 is reset and the bottom hook is engaged with the hook body at the front end of the blade 2, thus fixing it. The contact surfaces of the bottom hook of the rotating hook 62 and the hook body at the front end of the blade 2 are both provided with bevels and rounded corners to facilitate mutual squeezing and displacement. The specific shape can be understood with reference to the attached drawings.

[0030] The elastic clamping device 64 described in this invention is a torsion spring. The torsion spring is sleeved on the hinge shaft of the rotating hook 62. One end of the torsion spring is anchored on the rotating hook 62, and the other end is anchored on the inner wall of the front support shell. When the user inserts the blade 2 into the front support shell 3, the fixing hook 10 on the blade 2 strikes the inclined part of the rotating hook 62 and overcomes the torsion force of the torsion spring, thereby allowing the fixing hook 10 to be inserted into the rotating hook 62, and then the force of the torsion spring locks the fixing hook 10 in place.

[0031] The unlocking component 7 of this invention includes a limiting groove 65 disposed within the front support shell 3. A driving top block 66 is slidably disposed within the limiting groove 65, with its front end abutting against the rear side of the anti-rotation block 63. An unlocking crossbar 8 is slidably disposed on the rear side of the front support shell 3, with its front end abutting against the rear end of the driving top block 66. The driving top block 66 and the unlocking crossbar 8 can be separate components or integrally disposed as a long strip component. A safety component 9 is slidably mounted on one end of the unlocking crossbar 8 that passes through the outer wall of the front support shell 3. During installation, the blade 2 rotates along the fixed axis 22. The surfaces where the rotating hook 62 collides with the fixed hook 10 both have a beveled structure. When the rotating hook 62 presses against the fixed hook 10... When the fixed hook 10 is engaged, it overcomes the torque of the torsion spring, allowing the fixed hook 10 to engage with the rotating hook 62. The force of the torsion spring then locks the fixed hook 10, thus achieving the locking function. When unlocking, the driving unlocking crossbar 8 pushes the driving top block 66, and one end of the driving top block 66 pushes the anti-rotation block 63, thereby causing the rotating hook 62 to rotate and disengage from the fixed hook 10, thus achieving unlocking. In addition, firstly, the anti-rotation block 63 can limit the rotation of the rotating hook 62, preventing the rotating hook 62 from rotating too much due to the force of the torsion spring 64 and thus failing to engage with the fixed hook 10. Secondly, the driving top block 66 can push the anti-rotation block 63, thereby causing the rotating hook 62 to rotate and disengage from the fixed hook, thus achieving the unlocking function.

[0032] In this invention, the rear end of the unlocking crossbar 8 extends to the rear side of the front support shell 3 and is provided with a push button 71. A push button placement groove 72 is provided on the outer side of the front support shell 3. The push button 71 is movably disposed in the push button placement groove 72. With the setting of the push button 71, the unlocking crossbar 8 can be driven to move more comfortably and conveniently.

[0033] The safety component 9 of this invention includes a track groove 81 symmetrically arranged on the upper end of the push button 71. A safety locking block 82 that can slide up and down is provided in the track groove 81. The surface of the safety locking block 82 preferably has multiple anti-slip protrusions. A limiting notch 83 is provided on the upper side of the push button placement groove 72. A second spring 84 is connected between the track groove 81 and the safety locking block 82 to keep the safety locking block 82 extended into the limiting notch 83. When the safety is released, the safety locking block 82 is slid down along the track groove 81. At this time, the safety locking block 82 disengages from the wall of the limiting notch 83. Then, by pushing the safety locking block 82 and the push button 71 together into the push button placement groove 72, the unlocking crossbar 8 is driven to push the unlocking component 7 to unlock. In this way, it can first play the role of locking the limiting unlocking crossbar 8, and at the same time prevent the push button 71 from accidentally contacting foreign objects such as hockey sticks or hockey pucks, which would cause false locking, thus further ensuring the safety of the user.

[0034] See Figure 2-4As shown, a third spring 99 is connected between the front end of the drive top block 66 and the inner wall of the front support shell 3. Preferably, a third spring 99 is provided on both sides of the anti-rotation block 63, which can keep the drive top block 66 with a backward force, so that the drive top block 66 is more stably fixed in the limiting slide groove 65 and can ensure the smooth sliding of the drive top block 66.

[0035] To ensure that blade 2 is installed more stably and securely in mounting slot 5, please refer to... Figure 2 As shown in Figure 3, the fixing hook 10 and the U-shaped groove 11 on the blade 2 are roughly symmetrically arranged and close to the center of the blade 2, which can improve the bearing capacity of the blade 2, extend the service life of the blade 2, and at the same time ensure that the blade 2 is more stably and firmly installed in the mounting groove 5, thus ensuring the safety of the user.

[0036] To further enhance the fixing strength between the rotating hook 62 and the fixed hook 10, the rotating hook 62 and the anti-rotation block 63 are integrally formed of zinc alloy. Zinc alloy has the unique characteristics of all alloys, such as light weight, high strength, lower thermal conductivity than steel, and corrosion resistance.

[0037] The specific working principle of this invention is as follows: First, during installation, the U-shaped groove 11 is inserted into the fixed shaft 22. Then, the blade 2 rotates along the fixed shaft 22, causing the fixing hook 10 to extend into the front support shell 3 and engage with the rotating hook 62. The rotating hook 62 locks the fixing hook 10 in place, thereby firmly fixing the blade 2 in the mounting groove 5 through the limiting part 6 and the rotating hook 62. During disassembly, the safety block 82 is first pressed downwards along the track groove 81. At this time, the safety block 82 disengages from the limiting notch 83. Then, by moving the safety latch 82 and the push button 71 together into the push button placement slot 72, the unlocking crossbar 8 pushes the drive block 66 to move, and the drive block 66 pushes the anti-rotation block 63, thereby causing the rotating hook 62 to rotate and disengage from the fixed hook 10. Finally, by the elastic force of the first spring 93, the pop-out cylinder 92 pops out, thereby popping the front end of the blade 2 out of the mounting slot 5, thus achieving the unlocking function. Therefore, the installation and disassembly of the whole set is extremely convenient and fast, improving the speed of blade replacement.
