Description

A kind of ice blade disassembly and assembly locking structure

technical field

The invention relates to the field of ice racing equipment, in particular to a disassembly and assembly locking structure of an ice skate.

Background technique

Skating is a sport that uses skates to walk or race on ice. In the Winter Olympic Games, there are also a variety of skating events, such as: racing short track speed skating, speed skating and performance figure skating, as well as curling and ice hockey in recent years. Appeared on the field of the Winter Olympics, and at the same time, countries have gradually vigorously carried out mass participation in various ice sports.

In the existing ice sports, due to the intense high-speed sliding and the wear of the skates, there is a great impact on the skating, especially in ice hockey, figure skating and other sports with short blades and large longitudinal curvature, the skates can It is very important to be in the best state, so in the ice hockey game or figure skating scene, use the gap between the games to quickly sharpen the skates, which can be implemented without taking off the protective gear and skates to ensure that the skates are in the best sharp state. Skate skates for ice skating have become the best solution, but the existing skating blade replacement mechanism is very laborious and cumbersome to operate and has great potential safety hazards. For example, in curling and ice hockey, players wear thicker Protective equipment, it is very difficult to remove the skate with thick gloves on the hand, but removing the protective gear to remove the skate in the short gap of the game will have many unfavorable factors for the game. On the one hand, it may lead to When wearing the protective gear again, the adjustment is not optimal, and on the other hand, it will waste a lot of time. In addition, the ice slag deposited between the skates and the slashes on the commercial skates will condense after a long time of skating, making it difficult to disassemble the skates. For the weaker groups, the operation is also very unfriendly when the skates need to be replaced. In order to ensure that the removable skates are not easy to fall off during intense sports, the commercially available skates with replaceable skates usually use a strong torsion spring or high The hardness spring is used to realize that the locking part in the disassembly and assembly of the skating blade can be firmly clamped to the hook on the skating blade, so as to ensure that the locking part used to fix the skating blade will not be released due to external impact after the skating blade is installed. However, whether it is a professional ice hockey player or an ordinary consumer group, it is not easy to resist the large torsion force of the strong torsion spring or the elastic force of the spring in the process of disassembling and assembling the ice skates. For professional speed athletes, every game Competition time is very precious to them, and too much time cannot be wasted only on changing the skates. Furthermore, since the springs or torsion springs are usually made of metal, in skating, the ice is very difficult. It is difficult to avoid slag remaining in the ice blade holder, which is prone to rust of elastic parts made of metal. In addition to the cold nature of ice and snow movement itself, metal is more likely to be in a low temperature and rusted environment. Due to the hidden danger of breaking after being suddenly squeezed by external force, this is very dangerous for intense high-speed confrontation sports.

In addition, in the prior art, there is also a way of fixing the skate by using a folding wrench similar to the bicycle quick release assembly, that is, using a hook that can hook the hook on the skate, and at the hook of the hook The tail uses a wrench hinged on the skate holder. During the flipping process, the hook is pressed to compress the spring, and then the hook of the skate is released, so as to achieve a quick disassembly and assembly method. We found in the experiment, This kind of way of fixing the ice blade is very prone to the problem of the wrench being turned over after the external sharp object squeezes the wrench at the bottom of the hinge shaft. Since the top pressing part of this type of wrench is usually designed as an eccentric, so , it is basically unavoidable to flip over after being touched, which will cause very dangerous safety hazards to players or consumers participating in high-speed taxiing.

Therefore, there is an urgent need to improve the existing ice blade disassembly and locking mechanism.

The push-out portion 8 in the hook accommodating cavity 13 is described, so that the ice blade 14 can be disassembled faster, preventing the ice blade 14 from being blocked in the blade groove 11 due to ice slag, which makes disassembly difficult and affects the time for replacing the ice blade.

Wherein, the engaging member 20 includes: a locking hook member 21 that can be movably connected to the skate hook 141B in the hook accommodating cavity 13 in cooperation with each other, and a locking hook member 21 that is fixedly connected to the upper end of the locking hook member 21 The guide member 22, and the drive shaft 34 provided on the skate holder 10 for lateral rotation, the drive member 30 is arranged on the drive shaft 34, as shown in FIG. 2 and FIG. 3, this The guide member 22 in the embodiment is an elongated square block, and the bottom of the guide member 22 is integrally formed with a locking hook member 21 formed by bending backwards. The shape of the locking hook member 21 matches the skate hook 141B. In the embodiment, the bending direction of the hook body of the skate hook 141B is forward, and the bending direction of the locking hook member 21 is backward. If the bending direction of the hook body of the ice skate hook 141B is backward, the locking hook member 21 The bending direction of the hook member 21 is forward, and the bending direction of the hook member 21 will also change according to the shape of the ice blade that is actually matched. Moving back and forth, the guide groove 23 can be set at the front end of the guide member 22 or at the rear of the guide member 22. It should be noted that in this embodiment, when the guide groove 23 is set at the rear of the guide member 22, the tail end is an opening. The drain port is connected to the knife groove 11, and the bottom surface of the inner cavity of the guide groove 23 is a sloped surface with a high front and a low back, which can better enter the hook accommodating cavity 13. The ice slag and water are discharged to prevent the ice slag and water from freezing in the guide groove 23 and affecting the movement of the guide member 22. When it is arranged at the front end of the guide member 22, there is no need to set a drain port and a slope with a high front and a low back. In the embodiment, the ice blade 14 is inserted into the blade slot 11 first, wherein the ice blade hook 141A is aligned with the first card point 12 and inserted, and the ice blade hook 141B is turned over and inserted into the hook accommodating cavity 13, and the driving shaft is rotated by rotating the driving shaft. 34 Make the driving member 30 provided on it drive the guide member 22 with the locking hook member 21 at the bottom to move back and forth in the hook accommodating cavity 13. The ice blade hook 141B in the hook accommodating cavity 13 is hooked or released, so that the ice blade 14 can be locked in the blade slot 11 or released from the blade slot 11;

Among them, as shown in FIGS. 2 to 6 , an implementation of the driving member 30 in this embodiment includes a rack 33 fixedly formed on the guide member 22 , and the driving shaft 34 is fixedly provided with a rack 33 . There is a gear A35 that is coaxial with the drive shaft 34 and can be meshed with the rack 33. The rack 33 is fixedly formed on the top surface of the guide member 22. In addition, one end of the drive shaft 34 passes through The side wall of the ice blade holder 10 is provided with a screwing device 4 which can be turned over and opened at one end protruding from the outer side wall of the ice blade holder 10 to facilitate the rotation of the drive shaft 34 .

Figures 1, 3 to 6 show an embodiment of the screwing device 4: the screwing device 4 includes a hinged on the end of the drive shaft 34 and can pull the drive shaft 34 when it can be turned over and opened. The foldable locking wrench 41 displaced in the axial direction is provided on the drive shaft 34 located in the inner cavity of the skate holder 10 to drive the drive after the folding locking wrench 41 is turned over to be parallel to the side wall of the skate holder 10 . The return spring 5 for the reset of the shaft 34 (in this embodiment, one end of the return spring 5 is pressed against the side wall of the inner cavity of the ice blade holder 10 , and the other end is pressed against the gear A35 (driving member 30 ) fixed on the driving shaft 34 ), one end of the return spring 5 is pressed against the side wall of the inner cavity of the ice blade holder 10, and the other end is pressed against the gear A35 (driving member 30) fixed on the drive shaft 34. The folding locking wrench in this embodiment The articulation method of the 41 can be implemented with reference to the states shown in FIGS. 1 and 3 to 6 . The folding locking wrench 41 is a long-strip-shaped flip sheet with a rectangular notch at the bottom, and the drive shaft 34 is hinged at the bottom. In this rectangular gap, and the position must be close to the middle of the flip sheet, so that when the folding lock wrench 41 is turned over and opened, the drive shaft 34 can be pulled axially to the side of the skate holder 10 where the folding lock wrench 41 is located. The direction of the wall is displaced (refer to Fig. 3 and Fig. 5), and the return spring 5 is compressed at this time. When the folding locking wrench 41 is turned over to make the side wall fit parallel to the outer wall surface of the side of the skate holder 10, the return spring 5 is released, the drive shaft 34 can be axially displaced to the other side of the skate holder 10, and the side wall of the foldable locking wrench 41 is in contact with the side wall of the skate holder 10 (refer to FIG. 1, 4 and 6 ), and maintain such a fitted state to prevent the skating shoes from being hit and hit by the folding locking wrench 41 during sliding. In the embodiment, the side wall of the skate holder 10 where the folding locking wrench 41 is located is provided with an accommodating groove 411 that can accommodate the folding locking wrench 41 in the closed state, and is located at the side where the drive shaft 34 passes through. The diameter and width of the accommodating groove 411 at the position are larger than the width of the folding locking wrench 41, while the shape of the accommodating groove 411 located above the drive shaft 34 is basically the same as the length, width and height of the folding locking wrench 41, and is slightly larger than the folding locking wrench. The length, width and height of 41 are only 1MM, so that the folding locking wrench 41 can be further locked to prevent it from turning unexpectedly. Due to the contact surface with the skate holder 10 in the embodiment of the screwing device 4, when the folding locking wrench 41 is turned over to be parallel to the side wall of the skate holder 10, it can completely fit with the side wall of the skate holder 10, reducing the risk of The impact of external force is likely to cause the risk of the folding locking wrench 41 being opened by mistake, which increases the safety of the disassembly and assembly locking structure of the ice blade.

As shown in FIGS. 4 to 6 , in this embodiment, the locking portion 6 includes a slot 60 formed on the side wall of the inner cavity of the ice blade holder 10 that can clamp the teeth of the gear A35. When the drive shaft 34 is turned over to the closed state (refer to FIG. 1 , FIG. 4 and FIG. 6 ), the return spring 5 is released so that the drive shaft 34 is concentric and can be aligned with the The gear A35 meshed with the rack 33 moves in the direction away from the folding locking wrench 41 , and the slot 60 provided on the inner cavity wall of the skate holder 10 on the side away from the folding locking wrench 41 is just locked and displaced. The teeth of the gear A35 restrict the rotation of the gear A35. It can be seen from FIG. 5 and FIG. 6 that the width of the gear A35 in this embodiment is greater than the distance of its displacement. After the ice blade hook 141B in the hook accommodating cavity 13 is in the hooked state, the left and right displacement of the gear A35 will not cause the teeth to be separated from the rack 33, that is, when the gear A35 is displaced to In the slot 60, the bottom teeth of the gear A35 will be clipped into the slot 60 and the teeth of the rack 33 at the same time, and finally the folding locking wrench 41 is accommodated in the accommodating slot 411 to make it It cannot be rotated, and the ice blade 14 is completely locked. On the contrary, the lock hook 21 is removed from the skate hook 141B to complete the purpose of releasing and unlocking the skate 14. In addition, in repeated experiments and feedback from users, we found that after long-term skating, the skate needs to be replaced and sharpened. Or when the ice blade is replaced, the remaining ice slag in the blade groove 11 is condensed between the blade 14 and the blade groove 11, and sometimes it is difficult to pull out the blade with bare hands, especially when wearing gloves and other protective gear, so in this In the embodiment, when the skate 14 is unlocked, the push-out portion 8 on the engaging member 20 can simultaneously push the skate hook 141B out of the hook accommodating cavity (13) while unlocking the skate hook 141B. To achieve the effect of quick disassembly of the ice blade, specifically as shown in FIG. 2 , the push-out portion 8 includes a top pressing member 81 that is fixed on the bottom of the guide member 22 and extends downward. The bottom of the front side of the top pressing member 81 is provided with For some chamfers (in this embodiment, the rounded arc angle is used as an example), the chamfer is used to squeeze the skate hook 141B during the synchronous movement with the top pressing member 81 when the guide member 22 moves forward. The rear end of the top forces the skate hook 141B to move down. Since the skate hook 141A at one end of the skate 14 is still stuck on the first card point 12 at this time, the skate 14 is pressed against the top of the skate hook 141B by the pressing member 81 . At the rear end, the ice blade will be turned downward with the first card point 12 as the axis (please refer to Fig. 3). After the rear end of the ice blade 14 is pushed out of the slot 11, it can be easily removed. 14 will become faster, to prevent the ice blade 14 from being blocked in the blade groove 11 due to ice slag, which will make it difficult to disassemble. Users can be more friendly to use.

Figures 7 to 12 show the second embodiment of an ice blade disassembly and locking structure of the present invention. It can be clearly seen from the figures that this embodiment is basically the same as the first embodiment, except that the guide member 22 The formation of the guide member 22 is different from the implementation of the driving member 30 and the locking portion 6. In this embodiment, there are strip-shaped grooves 31 that can accommodate the driving shaft 34 to pass through the side wall of the guide member 22. The driving member 30 includes a rack 33 fixedly formed on a side wall of the guide member 22 located on the top plane of the strip groove 31 , and a rack 33 is fixed on the driving shaft 34 coaxial with the driving shaft 34 The gear A35 is central and can be meshed with the rack 33. In this embodiment, both ends of the drive shaft 34 are respectively rotatably fixed to the left and right side walls of the skate holder 10. When the skate hook 141B on the top of the skate 14 is inserted After the hook is accommodated in the cavity 13, the drive shaft 34 is rotated clockwise, and the gear A35 will rotate synchronously. Since the gear A35 meshes with the rack 33, the rack 33 will be driven to move when the gear A35 rotates, so that the gear A35 will move within the guide groove 23.
