Description

Technical Field

[0001] The invention relates to the field of ice and snow sports equipment, in particular to an ice skate quick locking structure. Background Art

[0002] Skating is an intense ice sport. The wear of ice skates, especially the change of curvature, has a great impact on skating. Especially for professional athletes, in order to maintain adhesion on the ice and skating speed during the game, the blades of ice skates must be replaced at any time. It is very important to grind the worn blades and maintain the curvature of the blades. However, the existing replacement structures of ice skates usually cannot firmly ensure that the ice skates are installed on the bottom of the shoes. Even if the replacement structures can be firmly installed on the bottom of the shoes, it is difficult to quickly achieve the purpose of changing the blades in operation, which is not conducive to athletes quickly and reliably changing ice skates in the midfield. In addition, most replacement structures are very complicated and cannot be popularized for use on ordinary commercially available products.

[0003] Therefore, the existing ice skate locking mechanism needs to be further improved. Summary of the invention

[0004] The purpose of the present invention is to provide a faster, safer and more reliable ice skate quick locking structure which can be widely used in commercially available and professional ice skates.

[0005] To achieve the above-mentioned purpose, the ice skate quick locking structure of the present invention adopts the following scheme:

[0006] The invention comprises a support shell installed on the bottom of the shoe, wherein a blade groove capable of accommodating the insertion of an ice skate is provided at the bottom of the support shell, and a first accommodation space capable of accommodating the hook at the front end of the ice skate and a second accommodation space capable of accommodating the hook at the rear end of the ice skate are respectively provided at the front and rear ends of the support shell, and the front and rear ends of the blade groove are respectively connected to the first accommodation space and the second accommodation space;

[0007] A first engaging member, which is disposed in the first accommodating space and can be used to engage with a hook at the front end of the ice skate;

[0008] A second engaging member, which is movably disposed in the second accommodating space, and one end of which can be used to engage with a hook at the rear end of the skate, and the other end of which passes through the bracket housing and extends out of the bracket housing;

[0009] A limiting member, which is connected to one end of the second engaging member outside the bracket housing and can drive the second engaging member to move forward and backward in the second accommodating space, and is used for locking or releasing the hook at the rear end of the skate;

[0010] A reset member is formed between the second engaging member and the bracket shell and can press the second engaging member to keep it in a forward position.

[0011] Furthermore, the first engaging member includes: hooks and columns which are laterally arranged in the first accommodating space and can be used to engage and fix the front end of the ice skate.

[0012] Furthermore, the second engaging member includes a pull rod movably arranged in the second accommodating space and capable of moving forward and backward, a stopper is fixedly sleeved on the circumferential outer wall of the pull rod, the reset member is arranged between the stopper and the inner wall of the second accommodating space, and a hook body capable of engaging with the hook of the rear end portion of the ice skate is connected to the end of the pull rod facing the first accommodating space, and the other end of the pull rod away from the hook body extends out of the bracket shell and is connected to the limiting member. The pull rod is maintained with a force in the direction of the first accommodating space under the action of the reset member, and the limiting member controls and limits the movement direction of the pull rod, so that the rear end portion of the ice skate can be removed or installed into the second accommodating space at any time after the force of the pull rod in the direction of the first accommodating space is released.

[0013] Furthermore, the limiting member includes a rotating column eccentrically hinged at the end of the pull rod, and a wrench capable of driving the rotating column to rotate is connected to the circumferential outer wall of the rotating column. A locking member capable of locking the rotation of the rotating column is also provided between the wrench and the bracket shell. The wrench can drive the rotating column to rotate along the hinge axis with the pull rod as the axis. Through the eccentric design, the pull rod can move forward and backward relative to the bracket shell.

[0014] Preferably, a receiving groove for accommodating a wrench is provided at the rear of the bracket shell, and the locking piece is arranged between the receiving groove and the wrench. The presence of the receiving groove can prevent the user from accidentally opening the wrench due to external factors during intense exercise, causing the ice skates to fall off, thereby further increasing safety.

[0015] Furthermore, the locking piece includes a locking hole arranged in the accommodating groove, and a locking block that can be inserted into and engaged in the locking hole is provided on the surface of the wrench facing the accommodating groove. After the locking block is engaged in the locking hole, it can more reliably prevent the wrench from being accidentally scratched and opened by external objects.

[0016] Preferably, a front-to-rear longitudinal guide groove is provided in the second accommodating space, and the pull rod is movably arranged in the guide groove. The pull rod can move forward and backward more stably relative to the bracket shell in the guide groove, thereby preventing the pull rod from swinging up and down, which would cause the hook body to be unable to engage with the hook at the rear end of the ice skate.

[0017] Furthermore, the reset member includes a spring sleeved on the pull rod, one end of the spring presses against the stopper, and the other end of the spring presses against the rear inner wall of the guide groove.

[0018] Preferably, the pull rod is also provided with a length adjustment structure capable of adjusting the length of the pull rod.

[0019] Furthermore, the length adjustment structure includes a threaded hole arranged at the end of the pull rod near the hook body, and a thread is provided on the circumferential outer wall at one end of the hook body, and the thread is screwed into the threaded hole. When the hook body is hooked on the hook at the rear end of the ice skate and is too tight or too loose, the distance between the pull rod and the hook body is increased or decreased by rotating the pull rod so that the threaded hole at the end of the pull rod cooperates with the thread at one end of the hook body, thereby adjusting the situation where the hook body is too tight or too loose when hooked on the hook at the rear end of the ice skate.

[0020] In summary, the present invention has the following beneficial effects compared with the prior art:

[0021] The present invention adopts the above-mentioned technology, and can adjust the distance between the pull rod and the hook body by rotating the wrench, so that the hook body can be hooked on the hook at the rear end of the ice blade more stably, and the pull rod can be driven forward or backward by flipping the wrench, so that the hook body at the front end of the pull rod can engage and hook the hook at the rear end of the ice blade, thereby realizing rapid disassembly and assembly of the ice blade. Through the accommodating groove provided at the rear part of the ice blade bracket, the wrench can be hidden in the accommodating groove, and the clamping block on the wrench cooperates with the clamping hole on the bracket shell located in the accommodating groove to further ensure that the ice blade will not fall off during skating due to scratches from external objects during use. Safety hazard, can provide a faster, safer and more reliable ice blade quick locking structure for commercially available ordinary skates and professional skates, and further optimize the structure for rapid replacement of ice blades.

[0031] Among them, it also includes a first engaging member 20 arranged in the first accommodating space 12, the first engaging member 20 is a post 21 arranged horizontally in the first accommodating space 12 and can be used to engage with the hook 2 at the front end of the ice skate 1, and a second engaging member 30 arranged in the second accommodating space 13 and can be used to engage with the hook 3 at the rear end of the ice skate 1, and the end of the second engaging member 30 facing the rear of the bracket shell 10 passes through the bracket shell 10 and extends out of the bracket shell 10; a limiting member 40 connected to the end of the second engaging member 30 located outside the bracket shell 10, the limiting member 40 can drive the second engaging member 30 to move forward and backward in the second accommodating space 13, and can be used to engage, lock or release the hook 3 at the rear end of the ice skate 1; a reset member 50 is formed between the second engaging member 30 and the bracket shell 10, and the reset member 50 can press the second engaging member 30 to keep it in a forward (towards the first accommodating space 12) force state.

[0032] like Figures 1 to 3 As shown, it can be clearly seen that in this embodiment, the second engaging member 30 includes a front-to-back longitudinal guide groove 131 provided in the second accommodating space 13, a strip-shaped pull rod 31 capable of moving forward and backward relative to the bracket housing 10 is provided in the guide groove 131, an annular stopper 32 is fixedly sleeved on the circumferential outer wall of the pull rod 31, the reset member 50 is provided between the stopper 32 and the inner wall of the second accommodating space 13, and a stopper 32 is connected to the end of the pull rod 31 facing the first accommodating space 12. The hook body 33 in the shape of a letter "7" can be engaged with the hook 3 at the rear end of the ice skate 1. The other end of the pull rod 31 away from the hook body 33 extends out of the bracket shell 10 and is connected to the limit member 40. The pull rod 31 is maintained in the direction of the first accommodating space 12 by the action of the reset member 50, and the limit member 40 controls and limits the movement direction of the pull rod 31. In this way, after releasing the force of the pull rod 31 in the direction of the first accommodating space 12, the rear end of the ice skate 1 can be removed from or installed in the second accommodating space 13 at any time.

[0033] In addition, if Figures 1 to 3 As shown, the limit member 40 in this embodiment includes a rotating column 41 eccentrically hinged at the end of the pull rod 31, and a wrench 60 that can drive the rotating column 41 to rotate is connected to the circumferential outer wall of the rotating column 41, and a receiving groove 61 that can accommodate the wrench 60 is provided at the rear end of the bracket shell 10, and a locking member 70 that can lock the rotation of the rotating column 41 is also provided between the receiving groove 61 and the wrench 60. The wrench 60 can drive the rotating column 41 to rotate along the hinge axis with the pull rod 31 as the axis. Through the eccentric design, the pull rod 31 can move forward and backward relative to the bracket shell 10.

[0034] Among them, Figures 1 to 3As shown, the locking member 70 includes a latch hole 71 arranged in the accommodating groove 61, and a latch block 72 which can be inserted into the latch hole 71 is provided on the surface of the wrench 60 facing the accommodating groove 61.
