[0053] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] like Figures 1-17 As shown, this utility model provides a portable, quick-assembly ice skate, including a retainer 1, a blade holder 4, and a blade 5; wherein:

[0055] The tool holder 4 is fixed to the bottom of the retainer 1; specifically, the tool holder 4 and the retainer 1 are connected by screws.

[0056] The blade 5 is installed at the bottom of the tool holder 4; specifically, the blade 5 is connected to the tool holder 4 by metal glue. In order to improve the installation strength, rivets are also included to connect the blade 5 to the tool holder 4.

[0057] The binding 1 is provided with a locking bar for engaging the fixing bar of the cross-country ski boot 6;

[0058] The fixing device 1 is also equipped with an automatic locking control component 2 for automatically locking and releasing the locking bar.

[0059] The ice skate provided by this utility model can be installed on the bottom of the cross-country ski boot 6. When wearing the cross-country ski boot 6 on an ice surface, it can be easily and quickly combined with the cross-country ski boot 6 to achieve ice gliding. It can also easily and quickly release the top fixing bar of the cross-country ski boot 6. At this time, the cross-country ski boot 6 will detach from the binding 1. The ice skate can be separated and connected to the upper boot without the aid of any special tools. The upper boot after separation can be used to walk like a normal shoe, which solves the problem that the ice skate cannot be quickly separated and connected to the upper boot without the aid of any special tools.

[0060] As an optional embodiment of this utility model, the blade holder 4 has a triangular cross-section, with a top plate 41 connected to the retainer 1 at the top and a blade slot 42 at the bottom for inserting the blade 5.

[0061] By employing a triangular blade holder 4 structure, the stability of the triangle structure is utilized to provide stable and durable performance when gliding on non-man-made ice surfaces (natural ice surfaces). The blade 5 is mainly fixed to the blade holder 4 with metal glue, and rivets provide double protection.

[0062] To reduce weight and buffer stress, in this embodiment, the tool holder 4 is provided with two buffer cavities, namely a first buffer cavity 43 and a second buffer cavity 44; the first buffer cavity 43 is cuboid and the second buffer cavity 44 is triangular.

[0063] In order to improve the applicability of the product and make it suitable for cross-country ski boots 6 of different sizes, in this embodiment, a number of connection holes 411 are provided on the top plate 41 to adjust the installation position of the fixing device 1.

[0064] Specifically, the binding 1 includes a front pedal 11 and a rear pedal 12. After the front pedal 11 is fixedly installed, the installation position of the rear pedal 12 can be adjusted according to the size of the shoe, so as to be suitable for cross-country ski boots 6 of different sizes and increase the applicability of the ice skates.

[0065] The surface of the blade holder 4 has pre-drilled mounting holes (connection holes) for the fixer. Users can adjust the position of the rear pedal 12 in the fixer 1 according to the size of the skate. Specifically, the fixer 1 is connected to the blade holder 4 of the ice skate by screws.

[0066] To improve the ice skate's passability, the tip of blade 5 has an arc-shaped structure.

[0067] The curved design at the tip of blade 5 allows for smooth passage through uneven, non-worked ice surfaces, improving the overall passability of the ice skate.

[0068] like Figures 1-17As shown, as a further improvement of this utility model, the fixing device 1 includes a front pedal 11 and a rear pedal 12 that are separately arranged; the locking rod is arranged on the front pedal 11, and the automatic locking control component 2 is arranged inside the front pedal 11 and connected to the locking rod; the automatic locking control component 2 can realize the automatic opening and automatic closing of the locking rod.

[0069] The binding device provided by this utility model, by setting the automatic locking control component 2, can realize the automatic opening and closing of the locking bar, thereby realizing the automatic locking when the binding bar of the cross-country ski boot is stepped in, and the automatic removal when the cross-country ski boot needs to be removed, without the need for manual locking and releasing, making it more convenient for users and easier and faster to operate.

[0070] As a further improvement of this utility model, the automatic locking control assembly 2 includes a support member 21, a fixing hook 22, a return spring 23, a fixing base 24, and a release block 26; wherein:

[0071] The front part of the front pedal 11 has a first hollowed-out portion 13 and a second hollowed-out portion 14 that are independent of each other;

[0072] The support member 21 is located at the bottom of the front pedal 11 and passes through the first hollow part 13;

[0073] The front pedal 11 is also provided with a slot 15 for securing the fixing rod of the cross-country ski boot 6; in order to realize the rotation and support of the release block 26, the front side of the support member 21 is provided with a hole for the rotating shaft 27 to pass through; the support member 21 is fixed to the bottom of the front pedal 11 by screws.

[0074] The fixed base 24 is installed on one side of the support 21, and the fixed base 24 is provided with a groove 25 at the corresponding position. The groove 25 is aligned with the slot 15 for inserting the fixing rod of the cross-country ski boot 6. Considering the strength of the pedal 1, in order to ensure the stable fixation of the cross-country ski boot, the fixed base 24 is provided. The groove 25 of the fixed base 24, the slot 15 on the front pedal 11 and the fixing hook 22 are used together to form a locking part, thereby achieving the stable fixation of the fixing rod.

[0075] The fixing hook 22 is slidably disposed within the support member 21 and the fixing base 24, and its top passes through the second hollow part 14 and engages with the opening positions of the groove 25 and the slot 15 to form a locking bar that locks the position of the fixing bar of the cross-country ski boot 6. When the fixing hook 22 moves away from the fixing base 24, the locking bar can be opened, and when the fixing hook 22 returns to its original position close to the fixing base 24, the locking bar can be closed.

[0076] One end of the return spring 23 is connected to the fixing hook 22, and the other end is connected to the support member 21. When the fixing hook 22 engages with the slot 15 and the groove 25, the return spring 23 is in a freely extended or compressed state. By setting the return spring 23, the automatic locking component 2 can be reset.

[0077] When the cross-country ski boots are put on, when the binding rod is stepped on the front pedal 11 of the binding, the binding rod will push the binding hook 22 to move towards the front end of the front pedal 11, thereby opening the locking rod. At this time, the binding rod smoothly enters the groove 25 of the fixing base 24 and the slot 15 of the front pedal 11. Then, the binding hook 22 automatically returns to its original position under the action of the return spring 23, and continues to lock the locking rod, thereby realizing the position locking of the binding rod and realizing the automatic insertion of the automatic cross-country ski boots 6.

[0078] In order to enable automatic unlocking and facilitate the separation and removal of cross-country ski boots, the release block 26 is rotatably mounted on the other side of the support 21 via the pivot 27; and the bottom of the release block 26 is provided with a push post 28 for the push fixing hook 22; the front end of the fixing hook 22 is provided with an adjustment groove 224 for the push post 28 to pass through.

[0079] When the cross-country ski boots need to be automatically unlocked, the release block 26 can be pressed. When the release block 26 rotates, the pusher 28 pushes the fixed hook 22 forward into the adjustment groove 224, causing the fixed hook 22 to leave the locked position, thereby opening the locking bar. At this time, the cross-country ski boots can be separated from the locking bar and removed.

[0080] As a further improvement of this utility model, a limiting wall 211 is provided inside the support member 21, and a connecting part 221 is provided on the fixing hook 22; the reset spring 23 is placed in the adjustment groove 224, with one end abutting against the limiting wall 211 and the other end abutting against the connecting part 221; and the limiting wall 211 passes through the adjustment groove 224, and when the fixing hook 22 is in the original position, there is a gap between the limiting wall 211 and the head end of the adjustment groove 224.

[0081] The fixed base 24 and the support 21 are fixed to the pedal 1 by screws.

[0082] This structural design limits both ends of the return spring 23. Furthermore, by setting the limiting wall 211, not only can one end of the return spring 23 be fixed, but it can also guide and limit the movement of the fixing hook 22, ensuring the stability of the forward and backward movement. In addition, the setting of the limiting wall 211 can also prevent interference between the return spring 23 and the push column 28, making it easier to install the return spring 23.

[0083] As a further improvement of this utility model, the fixing hook 22 includes a base plate 222, a latch 223, a connecting part 221, and an adjusting groove 224; wherein:

[0084] The substrate 222 is slidably mounted on the support member 21 and the fixed base 24;

[0085] Hook 223 is provided on the rear top side of substrate 222;

[0086] Adjustment groove 224 is provided at the front of substrate 222;

[0087] The connecting part 221 is provided on the top of the substrate 222 and is located at the rear end of the adjustment groove 224.

[0088] As a further improvement of this utility model, in order to limit the rotation angle of the cross-country ski boot 6 on the fixing device 1, a limiting block 3 is also included, which is installed on the support member 21 and located above the fixed base 24; the top of the limiting block 3 passes through the second hollow part 14.

[0089] The limiting block 3 has an internal hollow design, which limits the rotation angle between the binding 1 and the ski boot. The maximum rotation angle cannot exceed 45°. This design allows users to better control cross-country skis, cross-country rollers or ice skates.

[0090] When the cross-country ski boot is lifted relative to pedal 1, that is, when it flips, the position of the limit block 3 allows the flip angle to reach a maximum of 45°.

[0091] As a further improvement of this utility model, in order to facilitate the operation during automatic unlocking and ensure operational stability, a skewer slot 261 is provided on the side of the top of the release block 26 away from the rotating shaft 27.

[0092] When automatic unlocking of cross-country ski boots is required, the ski pole tip can be inserted into the pole slot 261 to remove the boot.

[0093] Furthermore, the pole insert 261 has an inverted trapezoidal structure that matches the shape of the ski pole head.

[0094] This utility model of bindings addresses the problem that existing bindings require manual locking and unlocking. To make it more convenient and quick for users, it implements an automatic step-in locking function for ski boots. By simply pressing the release block 26 of the binding with the tip of a ski pole, the ski boot can be separated from the binding, allowing users to use the binding more conveniently and quickly.

[0095] This utility model provides a cross-country ski boot 6, which includes the aforementioned ice skates.

[0096] When using the bindings, the user wears cross-country ski boots and can step directly into the slot of the binding. The binding will automatically lock the top bar of the cross-country ski boot. By using ski poles or pressing the release block with your fingers, the binding will release the top bar of the cross-country ski boot, at which point the cross-country ski boot will detach from the binding.
