Detailed description of the invention

As Figure 1-Figure 2, for a kind of snowshoe Double-drawing type fixator of the present utility model, comprise protecgulum 1, loose weaving band 2, first strains bracelet 31 and second and strain bracelet 32, first strip winding and buckle that the 41, second coiling is buckled 42, tightened ribbon 5, base 6, self-locking roller bearing buckle 7.

The particular location of above-mentioned critical piece with annexation is: the front end (following before two) of protecgulum 1 is fixedly connected with to form toe portions with base 6, to form footwear back backward above the middle part that the rear end of protecgulum 1 extends to base 6, first tension bracelet 31 and second strain bracelet 32 fix and Relative distribution in the rear end of protecgulum 1, the two ends of loose weaving band 2 are strained bracelet 31, second respectively and are strained bracelet 32 and be fixedly connected with first; Described first strip winding button 41 and the second coiling button 42 are separately fixed at the left and right sides in the middle part of base 6, the rear end of protecgulum 1 also offers the first through hole 11, second through hole 12 of Relative distribution, with reference to shown in Fig. 3, Fig. 4, described one end tightening ribbon 5 successively through the first through hole 11, first strip winding button 41, first tension bracelet 31, described in tighten the other end of ribbon 5 successively through the second through hole 12, second coiling button 42, second tension bracelet 32; Self-locking roller bearing button 7 is connected to form adjustable shoes heel with the afterbody two ends of base 6.

Wherein, the front end, first of base 6 and protecgulum 1 is strained bracelet 31, second and is strained between bracelet 32, and all passes through rivet between the first tension bracelet 31, second tension bracelet 32 and protecgulum 1.The two ends of pine weaving band 2 are each passed through after the first tension bracelet 31, second strains bracelet 32 unrolls loose weaving band 2 end of also sewing to achieve a fixed connection.It should be noted that, above-mentioned riveted joint and sewing connect only as the preferred embodiment of the present embodiment, and the such as welding of other routines, bonding, the mode such as to be threaded is applicable equally.

The operation principle of the utility model snowshoe Double-drawing type fixator is as follows:

First tightens process: acted on down by external force F1, F3 simultaneously and tighten ribbon 5 and strain bracelet 32(self-locking energy merit at the first tension bracelet 31, second) and base between slide to F1, F3 direction, and then slide to realize tightening instep in the first strip winding button 41 and the second coiling button 42, tighten heel by the elastomer tape of the lower 7 self-locking roller bearing buttons of external force F5 effect again, finally complete the safe locking effect realized on pin.

Second release process: when Double-drawing type fixator is locked at state on pin, by (being namely catch loose weaving band 2 with hand upwards to carry) under external force F2 effect, tighten ribbon 5 just to slide in the other direction to F1, F3 power and realize fixator protecgulum 1 and be separated from instep completely, more freely unclamp pin by the elastomer tape of the lower self-locking roller bearing button 7 of external force F6 effect to F5 disengagement in the other direction meeting and easily leave fixator.

As shown in Figure 5, self-locking roller bearing button 7 comprises a fastener base 10, one end of described fastener base 10 is toward being outside equipped with two relative support arms 101, one first bearing pin 21 is provided with between the free end of two support arms 101, described first bearing pin 21 is socketed with a roller bearing cylinder 20 that can rotate around it, the appearance of described roller bearing cylinder 20 is arranged with the locking belt 30 that can rotate around it, the surface of described locking belt 30 is provided with several locking holes 301 along its length direction, one second bearing pin 22 is also provided with between two support arms 101, described second bearing pin 22 is between the first bearing pin 21 and fastener base 10, this second bearing pin 22 is socketed with a fastener 40 that can rotate around it, described fastener 40 is provided with the latch 401 in the locking hole 301 that can insert on described locking belt 30, the second bearing pin 22 is also provided with one for driving described fastener 40 to rotate and torsion spring 50 in the locking hole 301 making the latch 401 on fastener 40 insert on locking belt 30 simultaneously.

The working mechanism of self-locking roller bearing button 7 is: drive fastener 40 to rotate by adopting torsion spring 50 and make the latch 401 on fastener 40 can aim in the locking hole 301 inserted on locking belt 30, when user needs the length regulating locking belt 30, can upwards mention locking belt 30, namely locking belt 30 is mentioned along the direction of putting forth effort F6, now locking belt 30 abuts against with the free end 400 of fastener 40 front end and promotes to rotate backward around the second bearing pin 22 after fastener 40 overcomes the active force of torsion spring 50, in the counter-rotational process of fastener 40, latch 401 is deviate from from the locking hole 301 of locking belt 30, now can regulate arbitrarily the length of locking belt 30, namely locking belt 30 can rotate arbitrarily around roller bearing cylinder 20, when unclamping locking belt 30, locking belt 30 reinstatement, the external force now put on fastener 40 is eliminated, the free end 400 of fastener 40 rotates near locking belt 30 around the second bearing pin 22 and makes the latch 401 on fastener 40 point to locking belt 30 under the effect of torsion spring 50, locking belt 30 is (namely locking belt 30 moves along the direction of putting forth effort F5) in the process of rotating around roller bearing cylinder 20, latch 401 can insert in locking hole 301 automatically, reach the function of self-locking, fast simple to operation, and by the snap-fit engagement of latch 401 from different locking holes 301, self-locking roller bearing button can be made can to have larger tightening force.

In addition, for the ease of installing torsion spring 50, make torsion spring 50 that fastener 40 can be driven better to rotate simultaneously, fastener 40 offers the pin shaft hole that described second bearing pin 22 can be allowed to pass, the sidewall of described pin shaft hole offers the torque arm 51 of described torsion spring 50 can be allowed to embed draw-in groove 402 in it, correspondingly, fastener base 10 or support arm 101 offer can with the pit bit 100 of another torque arm phase clamping of torsion spring 50.

The foregoing is only preferred embodiments of the present utility model, the utility model is not limited to above-mentioned embodiment, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
