It should be noted that, under the premise that the materials used for the first protrusion 34 and the second protrusion 35 are the same, the height of the protrusion of the second protrusion 35 can optionally be set higher than that of the first protrusion 34, so as to The pressing effect between the first positioning member 11 and the engaging portion 32 is further improved. Here, elastic materials such as sponge can be used for the first protrusion 34 and the second protrusion 35, because the sole surface of the boot 1 will first contact the first protrusion 34 and the second protrusion when the boot 1 is stepping on the fixer 2. 35 to contact, the toe part of the boot 1 after abutment is constrained by the toe fixing part to limit its upward movement, and further clamping effect is played due to the abutment effect, preventing the toe fixing part from colliding with the toe part during skiing. The toe part of the boot 1 is not fixed tightly, so there is abnormal noise and shaking. And when the material elastic deformation degree that first protrusion 34 adopts is greater than the material elastic deformation degree of second protrusion 35, the protrusion height of first protrusion 34 and second protrusion 35 can be consistent, as long as guarantee both and boots 1 is sufficient.

Principle of use:

As shown in the figure, the toe portion of the boot 1 is first inserted in the direction corresponding to the engaging portion 32, and during this process, the first positioning member 11 of the boot 1 is correspondingly engaged with the first restraining member 321 and the second restraining member 322. In the U-shaped groove formed, then, step the boots 1 as a whole downwards to abut against the bottom plate 21 of the holder 2, because the boots 1 press against the bottom plate 21 of the holder 2 to drive the supporting body 31 to pivot toward the direction A, and the supporting body 31 drives the clamping part 32 to pivot in the same direction, and when the boot 1 is fully stepped on the bottom plate 21, the supporting body 31 is in a horizontal position, and the second restraint part 322 on the clamping part 32 and the first positioning part 11 of the boot 1 The tight fit forms a fixation; when the clamping state needs to be released, the heel of the boot 1 is first unfixed, and the heel of the boot 1 is lifted up, and finally the toe part of the boot 1 is drawn out.

Of course, this embodiment does not specifically limit the manner in which the clamping portion 32 is driven to pivot, and in other embodiments, the pressing force of the boot 1 can be replaced by electric control or manual rotation, so that the clamping The connecting portion 32 is driven to pivot, so as to form an abutting state between the engaging portion 32 and the first positioning member 11 .

Example 2

This embodiment relates to a ski binding, including the clamping assembly as described in Embodiment 1.

As a further embodiment, the ski binding in this embodiment also includes a second positioning member 12 arranged on the heel of the boot 1, and a heel restraining member 22 fixed on the binding 2, the heel restraining The member 22 has a guide channel 24 for accommodating the second positioning member 12 to extend into. The heel constraining member 22 is rotatably provided with a clamping piece. The clamping piece has a coaxially fixed first protruding end 41 and a second extending end. Two protruding ends 42 , the first protruding end 41 protrudes into the guide channel 24 .

In the locked state of the boots, the second extended end 42 abuts against the outer side wall of the heel restraint member 22, so that the first extended end 41 blocks the guide channel 24; in the unlocked state of the boots, the first extended end 41 Pushed by the action of the second positioning member 12 extending into the guide channel 24 , the second extending end 42 is driven to pivot, so as to limit the position of the second positioning member 12 .

In this embodiment, as shown in FIG. 6 , the guide channel 24 on the heel constraining member 22 extends downward along the height direction. opening, so that the second positioning member 12 of the boot 1 extends downward into the guide channel 24 . Here, on the outside of the guide channel 24, that is, on the side of the heel constraining member 22 away from the heel of the boot 1, a pivot shaft is threaded, and the clip is sleeved on the pivot shaft, which correspondingly protrudes from the heel constraining member 22. One end of the outer wall is provided with an opening for the extension of the second extension end 42 .

In this embodiment, the shape of the second positioning member 12 is set in accordance with the guide channel 24, and the two side baffles 241 of the guide channel 24 that constitute the slot-type setting have the effect of relatively restricting the movement of the positioning member toward the front, so the guide channel 24 also has Resisting the effect of the forward movement tendency of the boot 1 , this setting is beneficial to avoid using additional straps to fix the boot 1 , and thus helps to reduce the putting on and taking off time between the boot 1 and the anchor 2 . Here, it should be noted that the guide channel 24 may not be provided with the baffle plate 241 , as long as it serves to guide the second positioning member 12 into the guide channel 24 .

Here, the clamping part in this embodiment also includes a biasing part provided on the heel constraining member 22, and the biasing part is used to abut against the outer wall of the heel constraining member 22 toward the second protruding end 42. connected bias force. As one of the specific implementation manners, the biasing member is an elastic member connected to the clamping member and the fixer 2 respectively. Elastic part can adopt existing mature torsion spring part, and its one end is attached to the bottom surface of first extension end 41, and the other end is attached to the side of heel constraint member 22, and the active force of this torsion spring is the aforementioned biasing force. pressure. Here, setting the biasing member can further ensure that the second protruding end 42 abuts against the outer sidewall of the heel restraining member 22 in a natural state, so as to ensure a stable clamping effect of the clip and prevent the second protruding end 42 when skiing. Accidental pivoting of end 42 affects the locked state of boot 1 .

It should be noted that, when the first extending end 41 is pivoted by the second extending end 42 , its final pivoted position should be enough to allow the second positioning member 12 to escape from the guiding channel 24 . As one of the implementations, the side wall surface in the guide channel 24 is recessed to form a relief groove, and the first extension end 41 enters into the relief groove after pivoting, thereby avoiding the contact between the first extension end 41 and the second positioning member. 12 interference; as an alternative embodiment, the side wall of the guide channel 24 may be hollowed out. In the hollow state, when the second extension end 42 is pivoted, the first extension end 41 can be driven to move, and the rotation of the second extension end 42 can push out the snow accumulated in the hollowed-out position, thereby further reducing the snow accumulation into the holder 2 Inside, it is conducive to maintaining a good fixed state.

As shown in Fig. 7 and Fig. 8, the aforesaid locked state of boots is the state in which the second positioning member 12 enters the guide channel 24 and is blocked by the first protruding end 41 in the natural state and cannot escape from the guide channel 24; the boots unlocked state is The state of blocking the guide channel 24 is released after the snap-in member is pivoted by the external force. It should be noted that, optionally, the second positioning member 12 is adapted to the shape of the guide channel 24 to further enhance the cooperation effect between the second positioning member 12 and the guide channel 24 .

In addition, the first protruding end 41 can optionally be a plate shaped corresponding to the guide channel 24. When the side wall of the heel constraining member 22 is hollowed out, the second protruding end 42 can optionally correspond to the heel constraining Due to the above-mentioned configuration, in the locked state, the first protruding end 41 blocks the upper opening of the guide channel 24, and in the skiing state, the first protruding end 41 blocks the guide channel all the time. 24. The second protruding end 42 always blocks the hollowed-out part of the heel restraining member 22, thereby preventing snow accumulation from entering the guide passage 24, and avoiding snow accumulation from freezing and affecting normal pivoting action.

As an alternative embodiment, the heel restraining member 22 in this embodiment is provided with a clamping plate 43 coaxially rotating with the clip, and the clamping plate 43 is located between the second extended end 42 and the heel restraining member. Between the outer side walls of 22 , the clamping plate 43 is adapted to drive the second extension end 42 to pivot in linkage, so that the first extension end 41 is free from blocking the guide channel 24 .

The specific structure is shown in Figure 8. The clamping plate 43 is an extension part coaxially fixed with the clamping member, and its free end is bent relative to the main body of the clamping plate 43 to form a bent part. The shape of the bottom end of the outer wall of the component 22 is adapted. In a natural state, the second extension end 42 of the biasing member has a tendency to pivot in the opposite direction to the B direction, and the second extension end 42 presses the clamping plate 43 to make the bending of the pressing plate The bent part abuts against the outer side wall of the heel restraining member 22 . In addition, the bent part can also be used as a handle, which is more convenient for the outside to operate the clamping plate 43 , so as to facilitate force application.

By setting the clamping plate 43, when the boot 1 tends to fall out of the guide channel 24 during skiing, the second positioning member 12 pushes against the end of the first protruding end 41 so that it pivots in the direction B in the opposite direction. Utilize the principle of leverage to make the bent part of the clamping plate 43 abut against the outer sidewall of the heel restraint member 22, thereby prolonging the moment arm of the second extension end 42, thereby helping to reduce the impact on the second boot when the boot is unlocked. The external force of the protruding end 42 makes the operation simple and labor-saving; in addition, the clamping plate 43 can extend downwards and be attached to the outer side wall of the heel restraining member 22, thereby facilitating the second protruding end 42 to have a stable pressure bearing capacity .

Principle of use:

The toe of the boot 1 is relatively downwardly inclined, and the clip of the boot 1 is aligned with the engaging slot 33 and then snapped into the toe fixing part, and then the heel of the boot 1 is aligned with the guide channel 24 and stepped down. During this process, the convex guiding surface of the second positioning member 12 pushes against the first extending end 41 to pivot in the B direction in the figure. When the second positioning member 12 passes over the first extending end 41, the second extending end 41 The end 42 is biased by the biasing member to drive the first extended end to pivot in the opposite direction of the B direction. Since the clip 43 is attached to the outer side wall of the heel restraining member 22, when the second extended end 42 is biased When the pressing piece biases against the clamping plate 43 , the second extending end stops pivoting, and the first extending end 41 blocks the guiding channel 24 again. When the boots 1 need to be pulled out, the external force pivoting clamp 43 pivots in the B direction, and the second extending end 42 drives the first extending end 41 to give way to the disengagement space of the second positioning member 12, and the boots 1 The heel first escapes from the guide channel 24, and then the boot 1 is displaced in the opposite direction to the toe relative to the fixer 2 so that the first positioning member is disengaged from the engaging slot 33.

An opening is provided to facilitate the extension of the second extension end 3204;

In this embodiment, the shape of the locating member is adapted to the setting of the guide channel 3202, and the side baffles 2021 of the groove-shaped guide channel 3202 have the function of relatively restricting the movement of the locating member toward the front, so the guide channel 3202 also has the function of resisting the movement of the boot 1 As a result of the forward motion trend, this setup has the advantage of avoiding the use of additional straps to secure the boot, thus reducing the time between boot and binding.

Here, the clamping assembly in this embodiment further includes a biasing member provided on the restraining member 3201, and the biasing member is used for biasing the second protruding end 3204 to abut against the outer wall of the restraining member 3201. . As one of the specific implementation manners, the biasing member is an elastic member connected to the clamping member and the fixer 2 respectively. The elastic member can be an existing mature torsion spring component, one end of which is attached to the bottom surface of the first protruding end 3203, and the other end is attached to the side of the constraint member 3201. The active force of the torsion spring is the aforementioned biasing force. Here, setting the biasing member can further ensure that the second protruding end 3204 abuts against the outer wall of the restraining member 3201 in a natural state, so as to ensure a stable clamping effect of the clamping member and prevent the second protruding end 3204 from Accidental pivoting affects the locked state of the boot 1 .

As shown in Figure 15 and Figure 16, as an alternative embodiment of the above structure, the biasing member is an electromagnetic transmission structure, and the second protruding end 3204 is attached to the binding member 3201 by the electromagnetic action of the biasing member. On the outer wall, and when the external force is greater than the electromagnetic force, the second extension end 3204 pivots along the direction A in the figure, thereby driving the first extension end 3203 to make way for the positioning block 3101 to escape from the guide channel 3202; The biasing member adopts other structural forms, as long as it is ensured that the second extending end 3204 has a tendency to be attached to the outer side wall of the constraint in a natural state. As another alternative embodiment, the biasing member may also be set as an active force that drives the first extending end 3203 to move against the direction A.

Of course, this embodiment does not specifically limit whether a biasing member is provided. In other embodiments, it can also be directly operated manually. As one of the implementation methods, a second The protruding end is attached with a locking piece that is locked in the state, and the locking piece can be an existing mature buckle, or other structural parts that are convenient for production and operation.

In addition, the included angles between the first extension end 3203 and the second extension end 3204 on the restraining member 3201 form an acute angle with each other. The end 3203 is inclined downward relative to the horizontal plane, so that the clamping effect between the first extending end 3203 and the positioning block 3101 can be further improved; at the same time, the inclined first extending end 3203 can facilitate guiding the positioning block 3101 into the guide The channel 3202 forms a clamping position behind, so as to have a smooth clamping state.

It should be noted that, when the first extension end 3203 is pivoted by the second extension end 3204 , its final pivoted position should be enough to make the positioning block 3101 escape from the guide channel 3202 . As one of the implementation methods, the side wall surface in the guide channel 3202 is recessed to form a relief groove, and the first extension end 3203 pivots and enters into the relief groove, so as to avoid interference between the first extension end 3203 and the positioning block 3101 ; As an alternative embodiment, the side wall of the guide channel 3202 may be hollowed out. In the hollow state, when the second extension end 3204 is pivoted, the first extension end 3203 can be driven to move, and the rotation of the second extension end 3203 can push out the snow accumulated in the hollowed-out position, thereby further reducing snow accumulation into the holder , is conducive to maintaining a good fixed state.

As shown in Figure 17 and Figure 18, the aforementioned boots locked state means that after the positioning block 3101 enters the guide channel 3202, it is blocked by the first protruding end 3203 in the natural state and cannot escape from the guide channel 3202; After the component is pivoted by an external force, the state of blocking the guide channel 3202 is released. It should be noted that, optionally, the positioning block 3101 is adapted to the shape of the guide channel 3202 to further enhance the cooperation effect between the positioning block 3101 and the guide channel 3202 .

In addition, the first protruding end 3203 can optionally be a plate shaped corresponding to the guide channel 3202. When the side wall of the constraining member 3201 is hollowed out, the second protruding end 3204 can be optionally formed corresponding to the constraining member 3201. Plate type, due to the above-mentioned settings, in the locked state, the first extended end 3203 blocks the upper opening of the guide channel 3202, and when in the skiing state, the first extended end 3201 blocks the guide channel 3202 all the time, and the second extended end 3201 blocks the guide channel 3202 all the time. The protruding end 3204 always blocks the hollow part of the restraining member 3201, thus playing a role of blocking snow from entering the guiding channel, and avoiding snow from becoming frozen and affecting normal pivoting action.

As shown in Figure 15 and Figure 16, the opposite lower end surface of the positioning block 3101 is an arc-shaped raised convex guiding surface 3103, when the positioning block 3101 moves downward, the convex guiding surface 3103 abuts against the first protruding end 3203 , and guide the first extension end 3203 to pivot in the A direction; the opposite upper end surface of the positioning block 3101 is an arc-shaped recessed concave guide surface 3102, and when the clip is pivoted in the A direction, the positioning block 3101 moves upward During the process, the concave guide surface 3102 abuts against the first extension end 3203 for pivoting, so that the lower convex surface 3103 of the positioning block 3101 can always be in contact with the first extension end 3203 during the whole process of pressing down the heel. In this way, the force applied to the end of 3203 is smoother and less labor-saving, which is conducive to improving the smoothness of the boots 1 entering and exiting the restraint 3201 and out of the restraint 3201, and reducing the interference between the first protruding end 3203 and the end face of the positioning block 3101 Causes a sense of resistance to the pivoting process. Here, the convex guide surface 3103 and the concave guide surface 3102 can be convex grooves with an arc-shaped cross section. When they are configured as convex grooves, the convex grooves on the positioning block should be made of wear-resistant and deformation-resistant materials.

As an alternative embodiment, the restraining member 3201 in this embodiment is provided with a clamping plate 3205 coaxially rotating with the clamping member, and the clamping plate 3205 is located on the outer side wall of the second extending end 3204 and the restraining member 3201 Between, the clamping plate 3205 is adapted to drive the second extending end 3204 to pivot in linkage, so that the first extending end 3203 is free from blocking the guiding channel 3202 .

The specific structure is shown in Figure 16. The clamping plate 3205 is an extension coaxially connected with the clamping member, and its free end is bent relative to the main body of the clamping plate 3205 to form a bent part. The shape of the bottom end of the outer side wall is adapted. In the natural state, the biasing member acts on the second extended end 3204 to have an opposite pivoting tendency to the direction A, and the second extended end 3204 presses the clamping plate 3205 to make the bending part of the pressing plate It abuts against the outer side wall of the constraint member 3201. In addition, the bent part can be used as a handle, which is more convenient for external operation of the clamping plate 3205, so as to facilitate force application.

By setting the clamping plate 3205, when the boots 1 have a tendency to fall out of the guide channel 3202 during skiing, the positioning block 3101 pushes against the end of the first extension end 3203 to pivot in the direction A in the opposite direction. The principle makes the bending part of the clamping plate 3205 press against the outer side wall of the restraint 3201, thereby prolonging the moment arm of the second extension end 3204, thereby helping to reduce the impact on the second extension end when the boot 1 is unlocked. The external force of 3204 makes the operation simple and labor-saving; in addition, the clamping plate 3205 can extend downwards and be attached to the outer side wall of the constraint 3201, so that the second extending end 3204 has a stable pressure-bearing capacity.

As shown in Fig. 12 and Fig. 15, in this embodiment, the snap-in assembly also includes clips arranged on both sides of the toe of the boot 1, and a mating slot 3206 provided on the holder 2, and a mating slot 3206 The opening is set toward the toe, so that the clip is suitable for snapping into the engaging slot 3206 . Here, when the boot 1 enters the fixer 2, the toe of the boot 1 is obliquely locked in the matching slot 3206 first, and then the positioning block 3101 on the heel of the boot 1 is aligned with the guide channel 3202 for fixed plugging. The baffle 2021 on the guide channel 3202 of the heel resists the forward movement of the boot 1, cooperates with the card slot 3206 to resist the upward or backward movement of the toe of the boot 1, and the clip can resist the upward movement of the heel of the boot 1, so that the boot 1 1 has a stable fastening effect and avoids relative displacement with the fixer 2.

In addition, this setting can also reduce the difficulty of putting on and taking off the boots, and the horizontal matching slot can make the boots put on and take off in various environments such as slope snow or powder snow, thereby improving the use effect of the binding. It should be noted that the direction of the fitting slot 3206 can also be set toward the heel, as long as the toe of the boot is snapped into the fitting slot 3206 .

As an alternative embodiment, the bottom plate 3207 of the fixture 2 is provided with a support pad 3208 suitable for supporting the boots 1. The support pad 3208 can be made of an existing mature wear-resistant anti-slip pad material, or a certain elastic material. Sponge pad, on the one hand, setting the support pad 3208 can further reduce the relative displacement between the boot 1 and the bottom plate 3207 of the holder 2; Supported by the support pad 3208 , it can be pressed against the matching slot 3206 , thereby further reducing the shaking and abnormal noise of the toe and the matching slot 3206 .

Principle of use:

The toe of the boot 1 is relatively downwardly inclined, and the clip 3104 of the boot 1 is aligned with the engaging slot 3206 and then shifted horizontally for a certain distance, and then the heel of the boot 1 is aligned with the guide channel 3202 and stepped down. During the process, the convex guide surface 3103 of the positioning block 3101 pushes against the first extension end 3203 to pivot in the direction A in the figure. The biasing effect returns to the state of abutting against the outer wall of the restraining member 3201 ; at this time, the second extending end 3204 is driven by the linkage action of the clamping plate 3205 to drive the first extending end 3203 to block the guiding channel 3202 again. When the boots 1 need to be pulled out, the external force pivoting clamp 3205 pivots in the direction A, and the second extending end 3204 drives the first extending end 3203 to give way to the disengagement space of the positioning block 3101, and the heel of the boots 1 Firstly, the guide channel 3202 is disengaged, and then the boot 1 is displaced in the direction of the toe relative to the fixer 2 to disengage the clamping part from the engaging slot 3206 .

Example 6

This embodiment relates to a ski binding, including a boot 1 and a binding 2, wherein the ski binding also adopts the clamping assembly as described in the fifth embodiment. Because the clamping assembly in the fifth embodiment is adopted, it has all the advantages in the fifth embodiment.

Example 7

This embodiment relates to a clamping assembly for a ski binding, including a positioning block 4101 disposed on the boot 1 , and a constraint 4201 fixed on the binding 2 .

Wherein, as shown in FIG. 19 and FIG. 20 , the positioning block 4101 is arranged at the heel of the boot 1 , and a fixing hole 4102 is provided inside the positioning block 4101 , and the fixing hole 4102 is set through opposite sides of the positioning block 4101 . In order to fix the boot 1 to the fixer 2, there should be other snap-fit parts besides the positioning block 4101 on the boot 1. There are existing mature snap-in structures, which will not be described in detail in this embodiment.

The restraint 4201 in this embodiment has a guide channel 4202 for accommodating the positioning block 4101, and a rotatable clamping member 131 is provided on the restraint 4201. The clamping member 131 is driven by external force The fixing hole 4102 is used to prevent the boot 1 from moving toward the toe or upwards at the limited position, and at the limited position, the engaging member 131 is interference-fitted with the fixing hole 4102 .

The specific structure is shown in Figures 21 to 4. On the guide channel 4202, there are two baffle plates 4204 that block the movement of the positioning block 4101 towards the direction of the toe. When the positioning block 4101 stretches into the guide channel 4202, the positioning block 4101 Restricted by the baffle plate 4204, the fixer 2 further plays a role in moving the boot 1 to the direction of the toe. Here, the cross section of the positioning block 4101 is set in a "T" shape, so as to match the shape of the guide channel 4202 and ensure the blocking effect of the baffle plate 4204 on the positioning block 4101 . Here, it should be noted that the baffle plate 4204 may not be provided on the guide channel 4202 , as long as the guide channel 4202 guides the positioning block 4101 to extend downward.

As shown in Figure 21, the restraint 4201 is integrally formed with the bottom plate of the holder 2. Compared with the split connection structure, the integral formation is beneficial to reduce the abnormal sound between the restraint 4201 and the bottom plate after the boot 1 is fixed. , so as to guarantee the skiing experience. The clamping part 131 is arranged on the outer side wall of the restraining part 4201, and a through groove 4203 arranged along the movement path of the positioning block 4101 is opened on the outer side wall, and the positioning block 4101 that goes deep into the guiding channel 4202 exposes the through groove 4203, so as to fit Insert the clamping member 131 into the fixing hole 4102 .

Here, the through groove 4203 on the restraining member 4201 can be an open groove with an opening formed on the upper end, or a square groove that is enclosed and formed around the outer wall of the restraining member 4201, and the through groove 4203 is exposed on the positioning block 4101. The part should be the part with the fixing hole 4102, so as to ensure that the clip 131 is plugged into the fixing hole 4102 of the exposed positioning block 4101 when the boot is locked. As an alternative embodiment, the part of the fixing hole 4102 on the positioning block 4101 does not completely protrude from the through slot 4203 , as long as it is ensured that the clip 131 can be plugged into the fixing hole 4102 . Here, it should be noted that the aforementioned locked state of the boots is a fixed state in which the heel of the boots 1 and the restraint 4201 of the holder 2 are snapped together, which will not be described in detail below.

In this embodiment, an opening is provided on the outer wall of the restraining member 4201, and a pivot shaft is constrained and limited in the opening. One end inside the restraining member 4201 forms a limited protrusion to prevent the pivot shaft from detaching from the hole. Here, the opening should be disposed relatively below the through groove 4203 to further accommodate the installation space of the clip 131 .

As shown in FIG. 23 and FIG. 24 , the clamping member 131 includes a main body 1312 hinged on the restraining member 4201 ; The bending direction of the engaging part 1311 should be consistent with the direction in which the engaging part 131 pivots and inserts into the fixing hole 4102; that is, as in this embodiment, the engaging part 131 pivots in the direction A, and the engaging part 1311 is relative to the main body 1312 It is bent toward the direction A, so as to ensure that the bent engaging portion 1311 is plugged into the fixing hole 4102 to form a fixing effect. As an alternative embodiment, the clamping piece 131 is set inside the guide channel 4202 corresponding to the constraint piece 4201. When the clamping piece 131 is set in the constraint piece 4201, the through groove 4203 may not be provided, and an operating handle is additionally provided to The locking member 131 is operated to pivot.

In this embodiment, the clamping assembly further includes a biasing member disposed on the restraining member 4201 , and the biasing member is adapted to exert a biasing force for pivoting the clamping portion 1311 toward the A direction. As one of the implementations, the biasing member adopts a torsion spring, and the torsion spring is sleeved on the pivot shaft, and one end of the torsion spring is constrained in the inner wall corresponding to the opening of the constraint member 4201, and the other end abuts against the opening of the clamping member 131. On the main body 1312, here, in order to prevent the clamping member 131 from over-pivoting beyond the through slot 4203, a stopper (not shown in the figure) that prevents the clamping member 131 from continuing to pivot in the direction A may also be provided on the restraining member 4201 ), as long as it is ensured that the engaging portion 1311 of the engaging member 131 is located at the limiting position under the natural state of being biased. Here, the limiting position is the position where the clip 131 is located when the boots are locked, and this embodiment will not be described in detail below.

Still as shown in FIG. 24 , in this embodiment, the end face of the engaging portion 1311 corresponding to the positioning block 4101 is an inclined wedge surface 1313 , which is suitable for being pressed by the positioning block 4101 to guide the engaging portion 1311 Pivot, so that the locking part 1311 unblocks the through slot 4203 . The setting of the wedge surface 1313 makes the end of the clamping part 1311 shaped into a tip, and the setting of the wedge surface 1313 can further guide the positioning block 4101 into the through groove 4203, reducing the resistance during the downward stepping process. The connecting portion 1311 is convenient to be plugged into the fixing hole 4102 to ensure the fixing effect.

When the boots 1 are stepping down, the positioning block 4101 first contacts the wedge surface 1313, and the wedge surface 1313 is pressed by the boots 1 to make the clip 131 pivot in the opposite direction of the direction A, and then the pivoting displacement exits. slot 4203, the positioning block 4101 can smoothly continue to enter the through groove 4203 downwards, and when the fixing block moves downward until the fixing hole 4102 is opposite to the wedge surface 1313 of the clamping piece 131, the clamping piece 131 is subjected to a bias force and makes The locking portion 1311 pivots in the direction A, so as to further facilitate the insertion of the locking portion 1311 into the fixing hole 4102 . It should be noted that after the bottom plate of the boot 1 and the holder 2 are in contact, it should be ensured that the fixing hole 4102 on the positioning block 4101 is set directly against the pivoted engaging part 1311, that is, the height of the positioning block 4101 of the boot 1 after stepping on it is equal to After pivoting, the engaging portions 1311 have the same height.

In this embodiment, as shown in Figure 24, the fixing hole 4102 on the positioning block 4101 is formed with an arcuate protrusion 4103 on the inner end surface corresponding to the clamping part 1311. When the boot is locked, the fixing hole 4102 is inserted into the boot. The engaging portion 1311 is disposed beyond the arc protrusion 4103 . As shown in Figure 24, the arc-shaped protrusion 4103 is formed on the lower side of the fixing hole 4102. The center line is at the highest point. During the plugging process of the engaging part 1311 from one end opening of the fixing hole 4102, the extended arcuate protrusion 4103 helps reduce the interference between the engaging part 1311 and the arcuate protrusion 4103, and ensures insertion into the fixing hole 4102 There is a stable locking effect between the locking part 1311 and the arc protrusion 4103 . As another alternative implementation manner, the arc protrusions 4103 may also have a plurality of them arranged at intervals along the insertion direction of the engaging portion 1311 .

In order to further improve the use effect of the clamping member 131, in this embodiment, the restraining member 4201 is provided with a clamping plate 1314 that cooperates with the clamping member 131. The connecting portion 1311 is disengaged from the fixing hole 4102 . Optionally, the clamping plate 1314 is set for the coaxial rotation of the clamping member 131, and a first protrusion 1315 is provided on the pivoting end of the clamping plate 1314, and a matching protrusion is provided on the pivoting part of the main body 1312 of the clamping member 131 the second protrusion 1316, when the clamping plate 1314 pivots in the reverse direction toward the A direction, the first protrusion 1315 pushes the second protrusion 1316 to drive the locking member 131 to move synchronously in the reverse direction of the A direction, so that The clamping member 131 escapes from the fixing hole 4102 . Here, the provided first protrusion 1315 and second protrusion 1316 can also function to limit the over-pivoting of the clip 131 over the through slot 4203 , so as to facilitate maintaining the working state of the clip 131 .

Of course, this embodiment does not specifically limit the installation position of the clamping member 131 , and in other embodiments, the clamping member 131 may also be disposed in a concave cavity inside the constraint member 4201 .

working principle:

When the boot 1 steps down and enters the retainer 2, the positioning block 4101 enters the guide channel 4202, moves to abut against the wedge surface 1313 of the clamping part 1311, and then continues to move downward. During this process, the wedge surface 1313 Guide the clip 131 to pivot in the direction A in the opposite direction to get out of the through slot 4203. When the positioning block 4101 moves down until the bottom surface of the boot 1 and the holder 2 are fully attached, the clip 1311 is deflected. The action of the pressure pivots along the direction A, and is plugged into the fixing hole 4102 to form a restrained and fixed state of the fixer 2 and the heel of the boot 1; when the restraint needs to be released, the operation clamp 1314 performs reverse pivoting in the direction A , the clamping part 131 is synchronously pivoted by the action of the clamping plate 1314 , so that the clamping part 1311 is separated from the fixing hole 4102 and the boot 1 can be lifted out.
