[0008] Preferably, a pin rod is installed on the inner wall of the back support, and a rocker plate is rotatably connected to the surface of the pin rod. A back pad is installed on the inner wall of the back support through a pin.

[0009] Preferably, a double torsion spring is installed on the surface of the pin rod and on the outside of the seesaw, with the center of the double torsion spring in close contact with the seesaw and the two ends of the double torsion spring in close contact with the inside of the back pad.

[0010] Preferably, the toe binding mechanism is composed of a large toe binding strap, a side toe binding strap, a toe oblique toothed strap, and a toe adjuster assembly. The left and right sides of the fixing base are respectively pinned with a side toe binding strap and a toe oblique toothed strap. A large toe binding strap is provided between the side toe binding strap and the toe oblique toothed strap, and the large toe binding strap and the side toe binding strap are interlocked. The large toe binding strap and the toe oblique toothed strap are adjusted and tightened by the toe adjuster assembly.

[0011] Preferably, the ankle binding mechanism is composed of a large ankle strap, a side ankle strap, a toothed ankle strap, and an ankle adjuster assembly.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] The structure of the snowboard binding provided by this utility model is as follows: Figure 1 as well as Figure 4 As shown, the device includes a retainer base 1, a back support 2 hinged to the rear side of the retainer base 1, a back pad 21 mounted on the inner wall of the back support 2 via a pin, a back plate 3 hinged to the inner wall of the back support 2, and a tension adjustment mechanism 4 provided between the back plate 3 and the back support 2. The tension adjustment mechanism 4 includes a limit seat 41, a knob screw 42, a downward pressure block 43, a rocker 44, a double torsion spring 45, and a pin rod 46. The tension adjustment mechanism 4 is used to adjust the tension of the back support 2.

[0027] During implementation, by stepping on the seesaw 44, the seesaw 44 pushes the back plate 3 back to its original position. When the snow boot is fully inserted, the seesaw 44 will be pressed against the downward pressure block 43.

[0028] Furthermore, such as Figure 4 as well as Figure 5As shown, a limiting seat 41 is embedded inside the back plate 3. A knob screw 42 is provided on the top of the limiting seat 41, and a downward pressure block 43 that can move up and down is connected to the bottom of the limiting seat 41. The bottom end of the knob screw 42 and the downward pressure block 43 are threaded together. A pin rod 46 is installed on the inner wall of the back support 2, and a rocker plate 44 is rotatably connected to the surface of the pin rod 46. A double torsion spring 45 is installed on the surface of the pin rod 46 and on the outside of the rocker plate 44. The center of the double torsion spring 45 is in close contact with the rocker plate 44, and the two ends of the double torsion spring 45 are in close contact with the inside of the back pad 21.

[0029] After putting on the snow boots, if the user feels that the back plate 3 is not tight enough, by rotating the knob screw 42, the knob screw 42 will push the downward pressure block 43 to move downward under the limit of the limit seat 41 to press against the position of the rocker 44, thereby making the back plate 3 rotate back and forth until the tightness of the back plate 3 is adjusted properly.

[0030] Furthermore, such as Figure 2 as well as Figure 3 As shown, a toe-binding mechanism 5 is provided on the front side of the fixing base 1. The toe-binding mechanism 5 is used for binding the toes. The toe-binding mechanism 5 is composed of a large toe strap 51, a side toe strap 52, a toothed toe strap 53, and a toe adjuster assembly 54. The side toe strap 52 and the toothed toe strap 53 with oblique teeth are respectively pinned to the left and right sides of the fixing base 1. The large toe strap 51 is provided between the side toe strap 52 and the toothed toe strap 53. The large toe strap 51 and the side toe strap 52 are interlocked. The large toe strap 51 and the toothed toe strap 53 are adjusted and tightened by the toe adjuster assembly 54.

[0031] During implementation, the toe side strap 52 is inserted into the toe large strap 51 and fastened, and then the toe oblique toothed strap 53 is tightened and fixed to the toe large strap 51 through the toe adjuster assembly 54.

[0032] Furthermore, such as Figure 3 as well as Figure 6 As shown, an ankle binding mechanism 6 is provided on the surface of the fixation base 1 and between the back support 2 and the back plate 3. The ankle binding mechanism 6 is used for binding the ankle. The ankle binding mechanism 6 is composed of a large ankle strap 61, a side ankle strap 62, an ankle oblique toothed strap 63, and an ankle adjuster assembly 64. The left and right sides of the fixation base 1 are respectively pinned to the side ankle strap 62 and the oblique toothed ankle strap 63. The large ankle strap 61 is provided between the side ankle strap 62 and the oblique toothed ankle strap 63. The large ankle strap 61 and the side ankle strap 62 are interlocked. The large ankle strap 61 and the oblique toothed ankle strap 63 are adjusted and tightened by the ankle adjuster assembly 64.

[0033] During implementation, the ankle side strap 62 is inserted into the ankle main strap 61 and fastened, and then the ankle oblique toothed strap 63 is tightened and fixed to the ankle main strap 61 through the ankle adjuster assembly 64.

[0034] Furthermore, such as Figure 6 , Figure 7 as well as Figure 8 As shown, both the toe adjuster assembly 54 and the ankle adjuster assembly 64 consist of a fixed base 7, an outer lever 8, an inner lever 9, and a locking block 10. The fixed base 7 is bolted to the surfaces of the toe strap 51 and the ankle strap 61. One end of the fixed base 7 is hinged to a locking block 10 with helical teeth via a pin. The helical teeth at the bottom of the locking block 10 mesh with the helical teeth of the toe helical toothed band 53 and the toe adjuster assembly 54 to achieve the locking function of the toe helical toothed band 53 and the toe adjuster assembly 54 after locking. The pin surface on one side of the locking block 10 is fitted with... There is a single torsion spring 101, one end of which is in close contact with the anti-reverse block 10, and the other end of which is in close contact with the fixed seat 7. The center part of the surface of the fixed seat 7 is hinged to an inner plate 9 by a pin. One end of the inner plate 9 is in close contact with the anti-reverse block 10 for locking. The other end of the fixed seat 7 is hinged to an outer handle 8 with helical teeth by a pin. The helical teeth of the outer handle 8 mesh with the helical teeth of the toe helical tooth belt 53 and the toe adjuster assembly 54. One end of the inner plate 9 passes through the outer handle 8, and the outer handle 8 is used for locking the inner plate 9.

[0035] When locked, the elastic force of the single torsion spring 101 will press down the oblique teeth of the anti-reverse block 10 to always engage with the oblique teeth of the toe oblique toothed band 53 and the ankle oblique toothed band 63, thereby pressing the toe oblique toothed band 53 and the ankle oblique toothed band 63 tightly. Then the inner plate 9 will press against the anti-reverse block 10 to form a first lock, while the outer handle 8 will press against the inner plate 9 to form a second lock. After the strap is locked, the inner plate 9 cannot be opened without opening the outer handle 8, and the anti-reverse block 10 will be in a locked state and will not disengage.

[0036] When adjustment is needed, the toe oblique toothed band 53 or the ankle oblique toothed band 63 can be moved forward by pulling the outer lever 8 upwards. The toe oblique toothed band 53 or the ankle oblique toothed band 63 can only move forward. When the outer lever 8 is opened first and then the inner lever 9 is pulled, the inner lever 9 will press the anti-retraction block 10 and lift it up, and the toe oblique toothed band 53 or the ankle oblique toothed band 63 can be disengaged, and the length of the toe oblique toothed band 53 or the ankle oblique toothed band 63 can be adjusted.

[0037] Compared to existing technologies, the snowboard bindings of this invention feature automatic wearing by stepping on the rocker arm 44, eliminating the need for two-handed operation and thus reducing effort and improving convenience. Furthermore, the invention incorporates a tension adjustment mechanism 4 to adjust the tightness of the backplate 3, allowing for compatibility with various ski boots and expanding the bindings' applicability. Additionally, the invention includes toe and ankle tightening mechanisms 5 and 6, respectively, providing adjustable tightness at the toes and ankle, enhancing comfort. The double locking mechanism further improves safety, preventing the bindings from coming undone as is common with existing bindings.

[0038] Working principle: When using, first fix the binding to the snowboard. After fixing, the user puts on the binding and puts on the snow boots. When putting on the binding, the user rotates the back plate 3 and the ankle fastening mechanism 6 to open the back plate 3 and the ankle fastening mechanism 6. The user puts on the snow boots and puts them into the binding between the back plate 3 and the ankle fastening mechanism 6. During the process of putting on the binding, the user will step on the rocker 44. The rocker 44 pushes the back plate 3 back to its original position. When the snow boots are fully put on, the rocker 44 will be pressed against the downward pressure block 43. Then, by adjusting the tension adjustment mechanism 4, the toe fastening mechanism 5 and the ankle fastening mechanism 6, the entire snow boot can be completely bound to the appropriate position.

[0039] When removing snow boots, adjust the adjusting components in the toe-tightening mechanism 5 and the ankle-tightening mechanism 6 to the longest position. Lift your foot, and under the action of the double torsion spring 45, it will automatically return to the position where the back plate 3 is opened, thus completing the boot removal action.

[0040] During installation, the toe-binding mechanism 5 and ankle-binding mechanism 6 of this utility model are secured by bolts to the fixing seat 7 onto the large toe-binding strap 51 and the large ankle-binding strap 61. When locking is required, the toe-toothed strap 53 and the ankle-toothed strap 63 pass through the toe-binding mechanism 54 and the ankle-binding mechanism 64. The elastic force of the single torsion spring 101 presses down on the oblique teeth of the anti-reverse block 10, which are permanently engaged with the oblique teeth of the toe-toothed strap 53 and the ankle-toothed strap 63, thereby pressing the toe-toothed strap 53 and the ankle-toothed strap 63 tightly. Then, the inner plate 9 presses against the anti-reverse block 10 to form a first lock, while the outer handle 8 presses against the inner plate 9 to form a second lock. After the straps are locked, the inner plate 9 cannot be opened without opening the outer handle 8, and the anti-reverse block 10 will be locked and will not disengage.

[0041] When the outer lever 8 is pulled upwards alone, the toe oblique toothed band 53 or the ankle oblique toothed band 63 can move forward. The toe oblique toothed band 53 or the ankle oblique toothed band 63 can only move forward. When the outer lever 8 is pulled open first and then the inner lever 9 is pulled, the inner lever 9 will press the anti-reverse block 10 and lift it up, and the toe oblique toothed band 53 or the ankle oblique toothed band 63 can be disengaged. The length of the toe oblique toothed band 53 or the ankle oblique toothed band 63 can be adjusted, thereby adjusting the tightness of wearing snow boots.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
