Detailed Implementation

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Please see Figure 1 - Figure 4 , Figure 7 , Figure 8 and Figure 10 This application provides a quick-release snowboard binding, comprising: Ski boots 100; The binding device 200 for fixing the ski boot 100, when the binding device 200 is in the open state, the ski boot 100 steps on the pedal 2085 inside the binding device 200 and presses down. The locking component 203 and the linkage side plate component 208 work together to close and lock the heel pressure plate 202. The binding device 200 and the ski boot 100 are then bound together, enabling the ski boot 100 to be put on and taken off quickly. The binding device 200 includes a foot support plate 201 that supports the bottom of the ski boot 100, a heel pressure plate 202 that presses down on the heel of the ski boot 100, a linkage side plate component 208 installed on the side of the foot support plate 201, and a locking component 203 that locks the heel pressure plate 202 and the linkage side plate component 208 together. An instep tightening component 205 is installed on the linkage side plate component 208 to press the ski boot 100.

[0021] In this embodiment, preferably, the fixing device 200 further includes a wedge-shaped heel back plate 204. The upper left end of the heel back plate 204 is connected to the lower end of the heel pressure plate 202. The heel back plate 204 includes two corners at its lower right end, which are respectively rotatably connected to the side of the foot support plate 201 and the linkage side plate component 208. When the fixing device 200 is in the locked state, the two corners at the lower right end of the heel back plate 204 are in a horizontal state. At the same time, the left end of the movable side plate 2081 is rotatably connected to the heel back plate 204, and the lower trapezoidal end of the movable side plate 2081 is in a horizontal state. That is, the heel back plate 204, the movable side plate 2081 and the foot support plate 201 are all horizontal. At this time, the heel pressure plate 202 forms an angle with the vertical direction and presses against the ski boot 100. The side of the foot support plate 201 is provided with a protective cover plate 2011. The protective cover plate 2011 can support the first locking plate 2033 and the second locking plate 2034, and also protect and cover them. The top of the protective cover plate 2011 has a storage groove 2012 for storing the locking pin 2031, and the locking pin 2031 is limited when it touches the bottom of the storage groove 2012.

[0022] In this embodiment, preferably, the linkage side plate component 208 includes: The movable side plate 2081 is installed on the side of the foot support base plate 201. The movable side plate 2081 is trapezoidal. The right corner of the heel back plate 204 is rotatably connected to the lower left corner of the movable side plate 2081, that is, a rotating shaft 2083 is provided between the two. A first linkage plate 2082 and a second linkage plate 2084 are rotatably installed on the inner left side of the heel back plate 204 and the upper left corner of the linkage side plate component 208. The inner ends of the first linkage plate 2082 are rotatably connected to each other. The rotatable connection between the two facilitates that when locked, the two can be folded and stored in the inner side of the movable side plate 2081 by relative rotation. And a foot pedal 2085 installed between the inner ends of two relatively distributed first linkage plates 2082, when the foot pedal 2085 moves downward and is subjected to force, it drives the first linkage plates 2082 and the second linkage plates 2084 to rotate and fold downward.

[0023] In this embodiment, preferably, the locking member 203 that cooperates with the linkage side plate member 208 to achieve the locking state includes: The locking pin 2031 installed on the inner side of the movable side plate 2081 is I-shaped. When it is engaged with the second lock core plate 2034, the I-shape can limit the front and rear directions of the second lock core plate 2034. A connecting shaft 2037 is installed on the inner side of the heel back plate 204. One end of the connecting shaft 2037 extends to the outer side of the heel back plate 204, and an operating wrench 2038 is provided at the end of the connecting shaft 2037. Both ends of the connecting shaft 2037 are provided with fan-shaped wheels 2036. The first lock cylinder plate 2033 and the second lock cylinder plate 2034 are located between the movable side plate 2081 and the protective cover plate 2011. The two lock cylinder plates can cooperate with each other to lock together, and can also cooperate with the lock pin 2031 to lock together. An extension rod is installed at the rear end of the sector wheel 2036. The rear end of the extension rod is connected to the lower end of the first lock core plate 2033, so that when the sector wheel 2036 rotates, it drives the first lock core plate 2033 to rotate around the guide shaft 2032. A tension spring 2035 is installed between the lower ends of the first lock core plate 2033 and the second lock core plate 2034 to facilitate the synchronous rotation of the two plates and change their angles.

[0024] In this embodiment, preferably, a guide shaft 2032 is provided between the upper end of the first lock core plate 2033 and the protective cover plate 2011, and the first lock core plate 2033 can rotate around the guide shaft 2032. A pivot is provided on the outer side of the protective cover plate 2011 to support the middle part of the second lock core plate 2034, so that the second lock core plate 2034 can rotate around the pivot. The upper end of the second lock core plate 2034 is bent forward, and when it cooperates with the lock pin 2031, it is not easy to disengage from the lock pin 2031.

[0025] In summary, when the binding device 200 is in the unlocked / open state, the size of the instep tightening component 205 is adjusted to the required size for wearing. The first linkage plate 2082 and the second linkage plate 2084 are extended to their maximum size. The left end of the movable side plate 2081 and the right end of the heel back plate 204 rotate upwards. The lower end of the first locking plate 2033 is biased forward, while the upper end of the second locking plate 2034 is biased backward and disengaged from the locking pin 2031. The fan-shaped wheel 2036 rotates biased forward, and the heel pressure plate 202 is biased outwards and away from the ski boot 100. When it is necessary to put the ski boot 100 on the binding device 200, the binding device 200 is changed from the unlocked state to the locked state. With the ski boot 100 inserted into the binding device 200 and the pedal 2085 pressed down, external force is applied, causing the pedal 2085 to move downwards. This causes the first linkage plate 2082 and the second linkage plate 2084 to rotate downwards and gradually fold, causing the movable side plate 2081 to rotate downwards. The connected heel back plate 204 then rotates downwards. The locking pin 2031 on the movable side plate 2081 moves downwards and contacts the arc-shaped extension block on the second locking core plate 2034. Pressing down the arc-shaped extension block causes the second locking core plate 2034 to rotate around the pivot. The upper end of the second locking core plate 2034 rotates forward and gradually locks onto the locking pin 2031, while the lower end of the second locking core plate 2034 moves backwards. The rotation causes the tension spring 2035 to stretch backward, which in turn causes the lower end of the first locking plate 2033 to rotate backward around the guide shaft 2032. The arc-shaped protrusion 20331 on the first locking plate 2033 is engaged in the arc-shaped slot 20341. The backward rotation of the lower end of the first locking plate 2033 causes the extension rod to move backward, which in turn causes the fan-shaped wheel 2036 and the connecting shaft 2037 to rotate backward. The operating wrench 2038 rotates backward to a near-horizontal position. The upper curved part of the second locking plate 2034 is close to the upper end of the first locking plate 2033, making it less likely to detach from the locking pin 2031. At this time, the ski boot 100 is fully placed on the footrest plate 201. The instep tightening component 205 presses against the instep of the ski boot 100, and the heel pressure plate 202 is driven by the heel back plate 204 to press against the heel of the ski boot 100. At this time, the binding device 200 is in a locked state, forming a fixed connection between the ski boot 100 and the binding device 200. When it is necessary to unlock again, hold the operating wrench 2038 to drive the connecting shaft 2037 and the fan wheel 2036 to rotate forward. The other parts move in the opposite direction to the unlocked state. When all parts are in the unlocked state, the ski boot 100 can be removed from the foot support plate 201. The whole process is convenient and quick, improving the efficiency of putting on and taking off the ski boot 100 and the binding device 200. Example 2

[0026] Reference Figure 6 This is the second embodiment of the present invention.

[0027] In this embodiment, preferably, the multiple slots on the second lock core plate 2034 and the arc-shaped protrusions 20331 on the first lock core plate 2033 cooperate with each other, which can further increase the locking effect when the two are locked with the lock pin 2031, and it is not easy to separate. The upper end of the second lock core plate 2034 is provided with an arc-shaped notch for the lock pin 2031 to be placed. The two can be locked quickly by engaging the lock pin 2031 and the second lock core plate 2034. The surface of the second lock core plate 2034 is provided with an arc-shaped slot 20341 located below the arc-shaped notch. The first lock core plate 2033 is provided with an arc-shaped protrusion 20331 that cooperates with the arc-shaped slot 20341 near the middle position. There is an arc-shaped extension block similar to the arc-shaped protrusion 20331 between the arc-shaped slot 20341 and the arc-shaped notch.

[0028] In this embodiment, preferably, the outer end of the first linkage plate 2082 is rotatably connected to the inner side of the heel back plate 204, and the outer end of the second linkage plate 2084 is rotatably connected to the upper left end of the movable side plate 2081. This facilitates the rotation of the heel back plate 204 and the movable side plate 2081 when the first linkage plate 2082 and the second linkage plate 2084 rotate. The front and rear ends of the pedal 2085 are respectively connected to the inner ends of the first linkage plate 2082 and the second linkage plate 2084, so that when the pedal 2085 is subjected to force, the first linkage plate 2082 and the second linkage plate 2084 rotate synchronously.

[0029] In this embodiment, preferably, a rear side plate is provided on the rear side of the foot base plate 201, and the right end of the movable side plate 2081 is slidably connected to the rear side plate. The rear side plate has a transverse sliding hole, and the side of the movable side plate 2081 is provided with a sliding column that slides with the transverse sliding hole. When the fixing device 200 is in the unlocked state, the slider is located in front of the sliding hole, and vice versa, it is located behind the sliding hole, which facilitates the rotation of the movable side plate 2081.

[0030] In summary, during use, when the pedal 2085 is subjected to a downward force, the first linkage plate 2082 and the second linkage plate 2084 rotate synchronously and move downward with the pedal 2085, causing the movable side plate 2081 to rotate downward. That is, the sliding column at the rear end of the movable side plate 2081 rotates during lateral sliding. In order to adapt to the rotation of the movable side plate 2081 and the heel back plate 204, the movable side plate 2081 will drive the sliding column to move backward in the lateral sliding hole. When it moves to the rear of the lateral sliding hole, the fixing device 200 is in the locked state. Conversely, when the front end of the movable side plate 2081 rotates upward, the sliding column slides forward in the lateral sliding hole, and the fixing device 200 is in the unlocked state. Example 3

[0031] Reference Figure 9 - Figure 12 This is the third embodiment of the present invention.

[0032] In this embodiment, preferably, the instep tightening component 205 can be adjusted to a suitable size according to the size of the individual ski boot 100, in conjunction with the foot support plate 201, and together with the toe tightening component 206, forms a multi-part fixation measure for the ski boot 100, further increasing the degree of fixation and compression of the ski boot 100, and increasing the safety of use. The instep tightening component 205, which is installed on the linkage side plate component 208 to press the ski boot 100, includes: A first rotating plate is installed on the inner side of the upper left end of the movable side plate 2081, and a first strap 2052 is provided on the other end of the first rotating plate. Multiple toothed grooves are evenly opened on the outer surface of the first strap 2052 along its length. The instep pressing strap 2051 is located between the two first rotating plates. The outer surfaces of both ends of the instep pressing strap 2051 are provided with first buckles 2053. The first buckles 2053 include teeth that cooperate with the tooth groove. The first buckles 2053 are detachably connected to the first strap 2052.

[0033] In this embodiment, preferably, a toe-tightening member 206 is provided at the top rear end of the foot support plate 201 to press against the toe of the ski boot 100. The toe-tightening member 206 can press against the toe of the ski boot 100, increasing the fixation safety of the ski boot 100. The toe-tightening member 206 includes: A second rotating plate is installed on the inner surface of the rear end of the movable side plate 2081 at one end, and a second strap 2062 is provided at the other end of the second rotating rod. Multiple toothed grooves are evenly opened on the outer surface of the second strap 2062 along its length. The toe-pressing strap 2061 is located between the two second rotating plates. The outer surfaces of the front and rear ends of the toe-pressing strap 2061 are provided with second buckles 2063. The first buckle 2053 includes teeth that cooperate with the tooth groove. The second strap 2062 is detachably connected to the second buckle 2063 to facilitate adjustment of the pressing size on the ski boot 100.

[0034] In summary, before the ski boot 100 is fixed to the binding device 200, the first buckle 2053 is opened, and its internal teeth disengage from the grooves on the first strap 2052. The first strap 2052 is pulled to adjust its length beyond the first buckle 2053, thereby adjusting the space between the first strap 2052 and the foot support plate 201 for the ski boot 100 to pass through. When the size is appropriate, the first buckle 2053 is closed, and its internal teeth engage with the appropriate grooves on the first strap 2052, thereby adjusting the overall size of the instep tightening component 205. Similarly, the size of the toe tightening component 206 is adjusted to fit the space for the toe of the ski boot 100, increasing the ease of wearing the ski boot 100. Example 4

[0035] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0036] When in use, the binding device 200 is in the unlocked state. Adjust the size of the instep tightening component 205 and the toe tightening component 206 to form a suitable space with the foot support plate 201 for easy wearing of the ski boot 100. When wearing the ski boot 100, step on the pedal 2085 to lock the linkage side plate component 208 and the locking component 203 together, which will drive the heel pressure plate 202 to rotate toward the ski boot 100, so that the binding device 200 is quickly fixed to the ski boot 100. During the wearing process, there is no need to bend over for a long time to put on and take off the ski boot. When taking off the ski boot, simply hold the operating wrench 2038 and pull it upward to a near-vertical position to complete the removal. The whole process is convenient and quick, improving the efficiency of putting on and taking off the ski boot.
