Description

Technical Field

[0001] The invention relates to the field of skate accessories, and in particular to a novel ice skate and a quick-release blade holder having the ice skate. Background Art

[0002] The blade is the core component of the skate, and its performance directly affects the skater's speed, stability, and the quality of the completion of technical movements. In sports such as speed skating, figure skating, and ice hockey, the design of high-quality ice skates can significantly improve the performance of athletes. By reducing the friction of the ice surface, ice skates enable athletes to skate efficiently, while providing the necessary stability to ensure the balance of high-speed skating and complex movements. And when completing difficult movements such as jumping, spinning, sudden stops, and quick turns, the design of the ice skates is particularly critical, which directly determines the completion effect of technical movements and competitive results.

[0003] Traditional ice skates mostly use a symmetrical thin-sheet design that is parallel to the left and right. Although this design has a certain degree of stability when skating, it exposes obvious limitations in difficult movements. In jumping movements, traditional ice skates have low take-off efficiency, and the impact force when landing is concentrated on the parallel blades, which makes it difficult to disperse the pressure and easily causes damage to the athlete's joints. When turning quickly, the parallel blades have insufficient contact area when the roll angle is large and cannot provide sufficient grip, which often causes the blades to slip, limiting flexibility and safety. In addition, during emergency stops, the parallel blades cannot fully cut into the ice surface, and insufficient friction leads to low stopping efficiency. At the same time, the center of gravity is unstable, increasing the risk of falling. These problems significantly limit the performance of athletes in competitions, especially in scenarios that require high flexibility and quick response, where traditional ice skate designs seem to be unable to cope.

[0004] In addition, with the advancement of skating technology and the increase in competition intensity, not only does the design of ice skates need to be optimized, but the rapid disassembly and assembly technology of ice skates has also become a research hotspot. This technology not only provides athletes with a convenient way to change equipment, but also significantly improves competition efficiency and safety. In high-intensity sports, ice skates may wear or be accidentally damaged due to frequent use. At this time, timely replacement of ice skates is crucial for athletes. However, traditional ice skates are usually fixed with screws or buckles, and require tools or cumbersome operating steps to complete the replacement, which obviously cannot meet the needs of racing against time in the game. Especially in ice hockey games, athletes wear heavy protective gear and protective gloves on their hands, which further increases the difficulty of traditional disassembly and assembly methods.

[0005] At present, many quick disassembly and assembly systems set the operation area at the tail end of the knife holder, and use a paddle device installed in the horizontal small hole slot to achieve one-handed disassembly. Although this design simplifies the disassembly and assembly process in theory, in actual operation, it is difficult for heavy gloves to accurately reach into the small hole slot to complete the operation. If athletes take off their protective gear for replacement, it will not only waste precious time, but may also affect the competition strategy due to failure to return to the original position in time. In addition, frequent removal of protective gear will also increase the risk of physical exposure of athletes during the game. Therefore, the existing quick-release technology still has a lot of room for improvement in meeting actual combat needs.

[0006] In summary, the existing ice skates and ice skate quick disassembly and assembly technology need to be further optimized and improved to better meet the needs of modern ice skating. Summary of the invention

[0007] The purpose of the present invention is to provide a new type of ice skates and a quick-release blade holder with the ice skates that can significantly improve the gliding stability, smoothness and speed, while effectively reducing air resistance and ice friction, solving the problems of low gliding efficiency and inflexible operation of traditional ice skates, and having an efficient and convenient locking and unlocking mechanism, which significantly improves the convenience of disassembly and assembly of the ice skates.

[0008] In order to achieve the above object, the present invention adopts the following scheme: a new type of ice skates, comprising: a blade body having a top and a bottom; The hook parts are arranged at intervals at the top of the blade body, and are used to cooperate with the ice skate holder, so that the blade body can be fixed on the ice skate holder; A connecting rib, which is disposed between the two hook portions and has a tooth-like structure, helps to evenly disperse the impact force caused by movement, is used to enhance the stability of the connection between the blade body and the skate holder, and avoids vibration or deviation caused by a loose connection; The blade part is set at the bottom of the blade body, and its cross section is trapezoidal, so that the bottom width of the blade part in contact with the ice surface is greater than the width of the blade body. This design increases the contact area between the bottom of the blade part and the ice surface, which can better disperse the impact force from the sliding process, enhance the grip, and improve the efficiency of braking and steering. When performing high-intensity actions such as emergency stops, turns or jumps, this design provides more stable support and reduces the risk of falling; The width of the front and rear ends of the blade is greater than the width of the central part, and the left and right edges of the bottom of the blade are inversely arched to reduce air resistance during skating. By optimizing the shape of the blade, air can flow around the skate more smoothly, reducing wind resistance during skating, thereby improving skating speed and efficiency. This design can significantly improve the performance of athletes who need to skate at high speed.

[0009] As a preferred solution of the present invention, the blade body, the blade portion, the hook portion and the connecting rib are integrally formed.

[0010] As a preferred embodiment of the present invention, the bottom surface of the blade portion in contact with the ice surface is in an arc shape with both ends tilted upward.

[0011] As a preferred solution of the present invention, the connecting rib includes a main tooth-shaped joint portion extending continuously along the length direction of the top of the blade body. The continuity of the main tooth-shaped joint portion improves the stability of the connecting rib, avoids loosening or dislocation between the blade body and the blade holder during movement, and ensures that the blade body is fixed on the blade holder more firmly, especially in the environment of high-speed movement and high impact, to avoid operational errors or safety hazards caused by unstable connection. Auxiliary tooth-shaped joint portions are respectively provided on the left and right sides of the main tooth-shaped joint portion, and the auxiliary tooth-shaped joint portion is staggered with the main tooth-shaped joint portion, and the height of the auxiliary tooth-shaped joint portion is lower than the main tooth-shaped joint portion. Through the staggered tooth-shaped joint, the connecting rib can effectively disperse the stress and impact force caused by high-speed movement or violent action at multiple contact points. The low height design of the auxiliary tooth-shaped joint portion not only helps to reduce weight and make the overall structure lighter, but also optimizes the force transmission path, avoiding excessive wear or fracture of the connection part caused by excessive concentrated stress. This structural design improves the strength and durability of the connecting rib and enhances the long-term reliability of the ice skates in fierce competitions.

[0012] The present invention also provides a solution for a quick-release tool holder, comprising a tool holder shell, wherein the tool holder shell is used to be connected to a shoe sole and has a cavity-shaped structure inside; An operating area is formed by being recessed from the center of the tool holder housing, and a groove communicating with the inner cavity of the tool holder housing is provided at the bottom of the operating area; A knife groove, which is recessed upward along the length direction of the bottom of the knife holder shell and is used to insert the new ice skate as described above; A front hook locking groove, which is arranged in one end of the blade groove and is used to lock one of the hook parts of the new ice skate; A rear hook locking groove, which is arranged in one end of the blade groove away from the front hook locking groove and is used to accommodate another hook portion of the new ice skate to be inserted; A locking rod is disposed in the blade holder housing and can slide forward and backward. One end of the locking rod is provided with a hooking end, which is used to hook the hook portion inserted into the rear hook locking groove when the locking rod moves forward, thereby locking and fixing the new ice skate; A pull bolt, which can be turned 90 degrees and connected to the end of the lock rod away from the hook end, and after the pull bolt is turned and folded into an upright state, it passes through the slot and extends upward into the operating area; When the pull bolt is manually pulled, the lock rod slides backwards, releasing the locking of the hook portion by the hook end, thereby unlocking the new ice skate, so that it can be removed from the blade holder housing; A first return spring is arranged behind the hooking end and is used to apply a return force to the locking rod after the locking rod moves backward, so that the locking rod returns to its initial position.

[0013] The above scheme realizes the rapid disassembly and assembly of ice skates by setting an operating area and a slot in the blade holder shell, combining the blade slot, front and rear hook lock slots, locking rod, hook end and pull bolt, so that athletes can quickly replace ice skates without the help of tools or complicated operations. This convenient operation is particularly important for high-intensity competitions, especially in sports such as ice hockey, where athletes can quickly adapt to changing competition environments. Among them, the locking mechanism cooperates with the front and rear hook lock slots and the hook end of the locking rod to ensure that the ice skates are firmly fixed during use, resist the impact force caused by intense exercise, and enhance the safety of ice skates during high-speed skating or intense exercise. At the same time, the first reset spring design enables the locking rod to reset automatically, which improves the smoothness of operation and the reliability of the system and avoids human errors in operation.

[0014] As a further solution of the present invention, a bolt lock is provided at the end of the bolt, which can lock the bolt in the slot and prevent it from turning over and standing upright, effectively preventing the bolt from accidentally loosening or turning over during sliding, and further ensuring operational safety.

[0015] As a preferred embodiment of the present invention, the pull-bolt lock includes a lock tongue groove arranged at the end of the pull-bolt, the head end and the top end of the lock tongue groove are open, a lock tongue is retractably arranged in the lock tongue groove, and an elastic arm is arranged at the tail end of the lock tongue to keep one end of the lock tongue extending out of the head end of the lock tongue groove. When the pull-bolt and the locking rod are in a straight line, the lock tongue is clamped on the inner wall of the tool holder shell at one end of the slot, and a safety device is arranged on the top of the lock tongue to lock the lock tongue so that it cannot be retracted into the lock tongue groove. The design of the pull-bolt lock further enhances the safety and stability of the quick-release tool holder. The lock tongue groove and the retractable lock tongue enable the lock tongue to clamp one end of the slot in the tool holder shell during the pull-bolt operation, ensuring that the pull-bolt will not flip upright due to the looseness of the pull-bolt when not in use or in a sliding state, thereby causing the hook end to accidentally unlock the hook portion. The pull-bolt lock solves the potential safety hazards in the traditional disassembly method, especially when athletes quickly disassemble and assemble the ice skates in high-intensity competitions. It can effectively prevent the ice skates from falling off or improper installation due to loose locking, and ensure that the ice skate disassembly and assembly system can still maintain high stability under high-frequency operations. This allows the design to meet the needs of rapid disassembly while ensuring the safety and reliability of the ice skates during use.

[0016] As a further solution of the present invention, the safety device includes a groove arranged at the top of the lock tongue, a seesaw with one end that can be turned up and down is hinged in the groove, a second return spring that can keep the seesaw in an upturned state is arranged on the bottom surface of the end of the seesaw away from its hinge axis, and a limiting inclined surface is arranged on the side wall of the groove located on the side away from the second return spring, and the end of the seesaw away from the second return spring is against the limiting inclined surface, so that the tail end of the seesaw is against the end surface of the top opening of the lock tongue groove, so that the lock tongue cannot be retracted into the lock tongue groove, and the design of the seesaw and the limiting inclined surface makes the lock tongue always in a stable locking position in the non-operating state, avoiding the lock tongue from retracting into the lock tongue groove and unlocking due to external vibration or unexpected force, thereby ensuring the reliability of the connection between the ice skate and the knife holder. An extension arm is connected to the seesaw, one end of the extension arm extends out of the groove and is connected to an operating button that can operate the seesaw to turn down, and the operating button is located in the operating area. The addition of the extension arm and the operating button makes the operation of the safety device more humane. The operating button is located in the operating area, which is convenient for users to press directly to trigger the rocker to flip down and unlock the lock tongue. This design ensures the locking strength while maintaining the convenience of the unlocking process, providing users with a fast and safe operating experience. This innovative structure greatly improves the functional integrity of the quick-release tool holder, making it suitable for scenarios that require frequent disassembly and assembly and have high safety requirements.

[0017] Due to long-term skating on the ice, ice can easily enter the gap between the ice blade and the blade groove and freeze the ice blade in the blade groove. Therefore, in actual use, it is often seen that when skaters remove the ice blade, they need to use a crowbar or a screwdriver to pry up the ice blade after unlocking it before they can pull it out. As a further solution of the present invention, a sealing ring is detachably embedded in the blade groove and around the blade body. By providing a sealing ring in the blade groove and a detachable design of the sealing ring, it is convenient for users to clean, replace or maintain the sealing ring during use, thereby ensuring the continued effectiveness of the sealing performance. This design improves the overall user experience of the quick-release ice blade, so that the unlocked ice blade can be easily pulled out, avoiding the embarrassment and inconvenience of using a crowbar or a screwdriver to assist in disassembly due to ice debris blocking the traditional quick-release structure. The bottom of the sealing ring is provided with a skirt extending outward along the bottom of the blade support shell, forming an additional protective barrier to further prevent ice debris from entering the blade groove from the side. This double protection structure not only effectively deals with the problem of ice debris intrusion caused by high-speed friction or external environment during skating on ice, but also reduces the wear and tear on the blade groove and blade surface caused by ice debris accumulation, thereby extending the service life of the ice blade and the blade groove.

[0018] As a further solution of the present invention, a first blade retraction slope is provided on the front side of the hook portion inserted into the rear hook lock groove, and a second blade retraction slope is provided on the hook end, which can cooperate with the first blade retraction slope to squeeze and push out the new ice skate in the blade groove from downward. During the unlocking operation, while the lock rod slides backward, the second blade retraction slope slides and squeezes the first blade retraction slope, squeezing and pushing out the ice skate from the bottom of the blade groove downward. This sliding fit utilizes the inclined force of the structural design, and the initial push-out of the ice skate can be completed during the unlocking process, reducing the resistance caused by ice chips or clamping, making it easier to remove the ice skate.

[0019] In summary, the present invention has the following beneficial effects compared with the prior art: First of all, the new ice skate of the present invention is particularly outstanding in the design of the blade part, adopting a trapezoidal cross-section structure and a unique bottom arc edge design, thereby significantly improving the sliding performance and handling stability. The trapezoidal cross-section makes the bottom width of the blade in contact with the ice surface greater than the width of the blade body. This design not only increases the force-bearing area and improves the stability during sliding, but also effectively disperses the pressure and reduces the resistance caused by the ice skate being embedded too deeply in the ice surface, especially in high-intensity sliding. In addition, the bottom of the left and right sides of the blade part adopts an arc edge to form an inverted streamlined structure. This design can significantly reduce the air resistance caused by ice cutting during sliding, increase the sliding speed, and reduce the vibration during sliding, thereby enhancing smoothness and flexibility. In particular, in the design where the width of the front and rear ends of the ice skate is slightly larger than that of the middle part, the arc edge cooperates with the trapezoidal cross-section to further optimize the stability of the sliding trajectory, making it easier for the skater to control the movement trajectory more accurately when turning or accelerating. This comprehensive improvement solves the problems of insufficient stability and large air resistance caused by the single design of traditional ice skates when skating, making the present invention have significant advantages in both competitive skating and daily skating scenarios, and greatly improving skating efficiency and comfort.

[0020] Secondly, the quick-release blade holder of the present invention overcomes the problem that the traditional quick-release ice skates need additional tools to pry out the ice skates through the exquisite cooperation of the pull bolt, the lock rod and the blade retraction bevel. The rear hook lock groove cooperates with the hook end of the lock rod to lock one of the hook parts, so that the installation and locking of the ice skates are stable and reliable. The first blade retraction bevel and the second blade retraction bevel cooperate with each other through the clever bevel, so that the ice skates can be automatically pushed downward when disassembled without the need for additional tools, which greatly improves the convenience of installation and disassembly. The design of the lock rod and the first reset spring ensures the automatic reset function after the unlocking action, which improves the operating efficiency and user convenience. In addition, in view of the phenomenon that traditional ice skates are easily difficult to disassemble due to ice chips freezing in the blade groove, the present invention effectively prevents ice chips from entering the blade groove by embedding a sealing ring in the blade groove and adding a skirt structure, greatly reducing the risk of freezing. The detachable design of the sealing ring is not only convenient for cleaning and maintenance, but also prolongs the service life of the ice skates. At the same time, the fit between the blade groove and the blade body is optimized, further improving the durability, reliability and ease of use of the quick-release structure.

[0036] The following specific implementation contents provide a variety of different embodiments or examples for implementing the present invention. Of course, these are only embodiments or examples and do not wish to be restrictive. In addition, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0037] In addition, spatially related words may be used, such as "below", "lower side", "from the inside out", "above", "upper side" and similar words. These relative words are for the convenience of describing the relationship between one element or feature and another element or feature in the drawings. These spatially related words include different orientations of the device in use or operation, as well as the orientations described in the drawings. The device may be turned to different orientations, rotated 90 degrees or other orientations, and the spatially related adjectives used therein may also be interpreted in the same way. Therefore, it cannot be understood as a limitation of the present invention. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0038] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments: Figures 1 to 4 A new type of ice skate shown in the figure comprises a blade body 1 designed as a symmetrical thin sheet parallel to the left and right, the blade body 1 having a top and a bottom, and two hook parts 3 protruding upward are arranged at intervals on the top of the blade body 1, which are used to cooperate with the ice skate holder, so that the blade body 1 can be fixed on the ice skate holder, wherein the front hook part 3 is a clamping ear 3a extending obliquely forward from the top of the blade body 1, and the rear hook part 3 is a hook 3b protruding upward from the top of the blade body 1. A connecting rib 4 with a tooth-like structure is arranged on the top of the blade body 1 between the clamping ear 3a and the hook 3b, and the connecting rib 4 comprises a main tooth-shaped joint part 41 extending continuously along the length direction of the top of the blade body 1, and auxiliary tooth-shaped joint parts 42 are respectively arranged on the left and right sides of the main tooth-shaped joint part 41, and the auxiliary tooth-shaped joint part 42 is arranged in a staggered manner with the main tooth-shaped joint part 41, and the height of the auxiliary tooth-shaped joint part 42 is lower than that of the main tooth-shaped joint part 41, so as to enhance the stability of the connection between the blade body 1 and the ice skate holder. The blade portion 2 is connected to the bottom of the blade body 1. The bottom surface of the blade portion 2 in contact with the ice surface is in an arc shape with both ends tilted upward, and the bottom surface of the blade portion 2 in contact with the ice surface is wider than the width of the blade body 1. Figure 3 As shown in the figure, the cross section of the blade portion 2 is trapezoidal. In this embodiment, the blade body 1, the blade portion 2, the hook portion 3 and the connecting rib 4 are integrally formed. Figure 4As shown in the figure, the width of the front and rear ends of the blade portion 2 is greater than the width of the central portion, forming the left and right edges of the bottom ends of the blade portion 2 to be inversely arched to each other, that is to say, although the central portion between the two wider ends of the blade portion 2 is also trapezoidal, its width gradually becomes narrower than that of the central portions at both ends. In addition to the two left and right edges of the bottom being inwardly concave inversely arched, the central waistline of the blade portion 2 is also inwardly concave inversely arched, which is beneficial to reducing air resistance during gliding. The inversely arched curve makes the shape of the bottom edge of the blade portion 2 cutting the ice surface during gliding more in line with fluid mechanics, allowing the blade to better fit the ice surface during inclined turns, reducing the local friction resistance when the blade portion 2 contacts the ice surface and providing stronger grip, which not only improves the gliding speed, but also allows the skater to complete sharp turns or changes of direction more easily.

[0039] In addition, if Figures 5 to 14A quick-release knife holder shown in the figure includes a knife support shell 5 for connecting to the sole of a shoe. The interior of the knife support shell 5 is a cavity-like structure. An operating area 50 is formed by a depression in the center of the knife support shell 5. Since the operating area 50 is in the center of the knife support shell 5, its size can be much larger than the hole groove possessed by similar quick-release mechanisms on the market, and it is easy to perform actions in the operating area 50 while wearing gloves. A slot 54 communicating with the inner cavity of the knife support shell 5 is provided at the bottom of the operating area 50. The slot 54 runs through the outer wall of the knife support shell 5 along the length of the knife support shell 5. An upwardly recessed knife groove 51 is provided along the length direction of the bottom of the knife support shell 5, and the new type of ice skates described above can be inserted into the knife groove 51. In order to fix the new type of ice skate as described above in the blade groove 51, the blade groove 51 has a tooth groove 55 at the top of the center that can match the auxiliary tooth-shaped joint part 42 and the main tooth-shaped joint part 41. A front hook lock groove 52 for accommodating the insertion of the hook 3a is provided at the front end of the blade groove 51. In this embodiment, the front hook lock groove 52 is connected with the inner cavity of the blade holder housing 5. When the hook 3a is inserted into the front hook lock groove 52, since the hook 3a is extended obliquely forward and upward, the front end of the front hook lock groove 52 will clamp the hook 3a so that it cannot be disengaged downward. A rear hook lock groove 53 is provided at the rear end of the blade groove 51. The rear hook lock groove 53 is also connected with the inner cavity of the blade holder housing 5 and can accommodate the insertion of the hook 3b. A guide groove 60 is provided from front to back in the knife holder housing 5, and a lock rod 6 is movably inserted in the guide groove 60. The lock rod 6 can slide forward and backward along the guide groove 60. A hook end 61 is provided at the tail end of the lock rod 6. The hook end 61 is in the shape of a hook with an opening facing downward, and is used to hook the knife hook 3b inserted into the rear hook lock groove 53. A first return spring 64 is provided behind the hook end 61. The top of the tip of the knife hook 3b is an inclined surface. When the knife hook 3b is inserted into the rear hook lock groove 53, the inclined surface of the knife hook 3b will squeeze the hook head of the hook end 61 backward, so that the entire lock rod 6 moves backward. When the hook head of the knife hook 3b passes over the hook head of the hook end 61, the first return spring 64 applies a return force to the hook end 61, so that the hook end 61 moves forward to hook the knife hook 3b, and the lock rod 6 returns to the initial position. In this way, the new ice skate is locked and fixed in cooperation with the rear hook lock groove 53. When unlocking the knife hook 3b, the lock rod 6 is moved backward again, and the hook end 61 can release the knife hook 3b again. In order to facilitate the backward movement of the lock rod 6, a pull bolt 62 is hinged at the end of the lock rod 6 away from the hook end 61. The pull bolt 62 can be turned up 90 degrees to an upright state. The hinge axis of the pull bolt 62 is provided with a torsion spring 67 that can keep the pull bolt 62 turned up and folded to an upright state. It can be clearly seen from the figure that when the pull bolt 62 is turned up and folded to an upright state, it passes through the slot 54 and extends upward into the operating area 50, and the end of the pull bolt 62 at the hinge will abut against the end of the lock rod 6, which is convenient for pulling the lock rod 6 to move backward. When in use, the upright pull bolt 62 is manually pulled backward to make the lock rod 6 slide backward, and the hook end 61 is released from the lock of the knife hook 3b.A first blade-retracting slope 31 is provided at the front side of the knife hook 3b inserted into the rear hook lock groove 53, and a second blade-retracting slope 66 is provided on the hook end 61, which can cooperate with the first blade-retracting slope 31 to squeeze and push out the new ice skate in the knife groove 51. When the hook end 61 releases the hooking state of the knife hook 3b, the pull bolt 62 is continuously pulled backward, and the first blade-retracting slope 31 on the hook end 61 squeezes the second blade-retracting slope 66 on the back of the knife hook 3b, so that the tail end of the knife body 1 moves downward from the knife groove 51, and the operator can conveniently pull the entire new ice skate out of the knife groove 51, so that it can be disassembled from the knife support housing 5.

[0040] During the skating process, the friction between the ice skates and the ice surface generates a large amount of small ice chips. These ice chips enter the gaps and accumulate under the action of the sliding pressure. In addition, due to the influence of the thermal expansion and contraction effect, the ice skates are heated by friction, and the ice chips freeze quickly in a low temperature environment, further embedding the gaps. As a result, it becomes difficult to pull out the ice skates after a long period of skating. It is necessary to use tools such as crowbars to forcibly pry them out, which is not only time-consuming and labor-intensive, but may also damage the connection structure between the ice skates and the blade groove, reducing the service life of the ice skates. Therefore, the present invention has a sealing ring 9 detachably embedded in the blade groove 51 and around the blade body 1. The bottom of the sealing ring 9 is provided with a skirt 91 extending outward along the bottom of the blade support shell 5. By detachably arranging the sealing ring 9 in the blade groove and the design of the skirt 91 extending outward, ice chips are effectively prevented from entering the gap between the blade body 1 and the blade groove 51, which is convenient for users to clean, replace or maintain the blade groove 51 and the sealing ring 9 during use, ensuring the continued effectiveness of the sealing performance. This design improves the overall user experience of the quick-release ice skates, allowing the new ice skates to be easily pulled out after being unlocked, avoiding the embarrassment and inconvenience of using a crowbar or screwdriver to assist in disassembly due to ice jams in traditional quick-release structures. In addition, in order to facilitate the disengagement of the sealing ring 9 from the knife groove 51, a triangular block 92 extending upward and bypassing the top of the knife body 1 is provided at the top of the sealing ring 9, and the tail end of the hook end 61 is also a slope. When the second knife withdrawal slope 66 squeezes the knife hook 3b downward, the tail end of the hook end 61 will squeeze the triangular block 92 at the same time, so that the sealing ring 9 can be disengaged from the knife groove 51. It should be noted that in order to prevent the sealing ring 9 from being disengaged from the knife groove 51 during sliding, a hanging ring 93 bypassing the top of the knife body 1 is provided at the top of the sealing ring 9 corresponding to the front hook lock groove 52. It should also be noted that in order to prevent foreign objects or ice from falling into the slot 54 in this embodiment, a cover plate 68 with the same shape as the slot 54 is provided on the top of the locking rod 6. When the locking rod 6 is in the initial position, the cover plate 68 will be inserted into the slot 54 behind the pull bolt 62 to close this part of the slot 54.

[0041] When the top end of the blade body 1 is inserted into the blade groove 51 and the hook end 61 is hooked and locked to the blade hook 3b, that is, when the new ice skate is completely installed on the blade holder housing 5, the pull bolt 62 is turned over to be in a straight line with the locking rod 6, in order to prevent the pull bolt 62 from being accidentally loosened or turned over during sliding, such as Figures 7 to 14 As shown, a bolt lock buckle 7 is provided at the end of the bolt 62, which can lock the bolt 62 in the slot 54 and prevent it from turning over and standing upright. The bolt lock buckle 7 includes a lock tongue groove 65 arranged at the end of the bolt 62, and the head end and the top end of the lock tongue groove 65 are open. A lock tongue 71 is telescopically provided in the lock tongue groove 65, and an elastic arm 72 is provided at the tail end of the lock tongue 71 for keeping one end of the lock tongue 71 extending out of the head end of the lock tongue groove 65. The bottom surface of the head end of the lock tongue 71 is an inclined surface. When the bolt 62 and the locking rod 6 are in a straight line, the lock tongue 71 is stuck on the inner wall of the knife support shell 5 at one end of the slot 54.

[0042] In order to prevent the lock tongue 71 from accidentally retracting, causing the pull bolt 62 to spring up, thereby causing a potential safety hazard, a safety device 8 is provided on the top of the lock tongue 71 to lock the lock tongue 71 so that it cannot retract into the lock tongue groove 65. Specifically, the safety device 8 includes a groove 73 arranged at the top of the lock tongue 71, and a seesaw 81 with one end that can be flipped up and down is hinged in the groove 73. The bottom surface of the end of the seesaw 81 away from its hinge axis is provided with a second return spring 82 that can keep the seesaw 81 in an upturned state. A limiting inclined surface 83 is provided on the side wall of the groove 73 located on the side away from the second return spring 82, and the end of the seesaw 81 away from the second return spring 82 is abutted against the limiting inclined surface 83, so that the tail end of the seesaw 81 abuts against the end surface of the top opening of the lock tongue groove 65, thereby preventing the lock tongue 71 from retracting into the lock tongue groove 65. An extension arm 84 is connected to the seesaw 81, one end of the extension arm 84 extends out of the groove 73 and is connected to an operating button 85 that can operate the seesaw 81 to flip down, and the operating button 85 is located in the operating area 50. When the locking bolt 71 cannot be retracted into the bolt groove 65, one end of the rocker plate 81 is pushed upward by the second return spring 82 and abuts against the end surface of the top opening of the bolt groove 65, so that the bolt 71 cannot be retracted into the bolt groove 65. When unlocking, the operating plate 85 is pressed to move the rear end of the rocker plate 81 downward to be offset from the end surface of the top opening of the bolt groove 65, and then the operating plate 85 can be moved to drive the bolt 71 to retract into the bolt groove 65. In this way, the pull bolt 62 can flip up under the action of the torsion spring 67.
