Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of physical education roller skate with ankle defencive function, include skidding shoe body 4, the welt of skidding shoe body 4 Opening position is equipped with lower protection ring 3, and the lower upper surface of protection ring 3 is hinged with six damping springs 2, each damping spring by Hooke's hinge 2 upper ends are equally articulated with upper protection ring 1, each lower end hinged place of damping spring 2 damping spring 2 adjacent with side with Hooke's hinge The adjacent arrangement in lower end hinged place, the adjacent arrangement in upper end hinged place of the upper end hinged place damping spring 2 adjacent with its opposite side, Six damping springs 2 it is overall it is W-shaped is circumferentially annularly distributed between protection ring 1 and lower protection ring 3, adjacent damping spring 2 it Between be in 30 ° to 40 ° angles, upper protection ring 1 is placed on shank appropriate location more than sportsman's ankle, and wherein damping spring 2 has Allow to move during low speed, the locking when speed or acceleration exceed corresponding value, form the characteristic of rigid support.

Upper protection ring 1, damping spring 2, the lower outer layer of protection ring 3 are enclosed with flexible material, to prevent itself and human body during motion Hard contact causes sportsman's wound.

Lower protection ring 3 and upper protection ring 1 are by protection semicircular ring A 11, and protection semicircular ring B 12, spacing spine block 13 is spacing Torsion spring 14 forms, and protection semicircular ring A 11 is semi-annular shape structure, and its semicircular ring one end is connected with locating dowel, and the other end is connected with Positioning tooth bar, positioning tooth bar outside offer ratchet, and protection semicircular ring B 12 is also semicircle ring structure, and its semicircular ring both ends is opened Provided with the positioning hole to match with the locating dowels of semicircular ring A 11 and positioning tooth bar, wherein the adjacent positioning to match with positioning tooth bar Hole is further opened with cavity, installs limited location spine block 13 in cavity and spacing torsion spring 14, spacing one end in cavity of spine block 13 are hinged, The other end is connected on the locating dowel ratchet being inserted into its positioning hole, and spacing torsion spring 14 is sleeved on the hinge position of spacing spine block 13 Put, one, two torsion spring arm is connected to protection semicircular ring B 12 cavity sidewalls, and another is connected on spacing spine block 13.

Specifically used method：

Before wearing, spacing spine block 13 is first pulled, respectively by the protection of the upper protection ring 1 in this roller skate and lower protection ring 3 Semicircular ring A and protection semicircular ring B are separated, and after dressing this good roller skate, are again fastened protection semicircular ring A and protection semicircular ring B Annulus is integral, protection ring 3 is fixed on skidding welt at present for this, and upper protection ring 1 is surrounded on shank position.

When roller skating person carries out roller skating, the meeting of damping spring 2 that is connected between upper protection ring 1 and lower protection ring 3 And guarantee upper protection ring 1 flexible according to Athletess state has the free degree of any direction activity, so as to not interfere with pin The motion of ankle any direction, but simultaneously because damping spring allows to move when having low speed, in speed or acceleration more than corresponding Locking during value, the characteristic of rigid support is formed, so when occurring easily to cause the high speed or High acceleration motion of ankle from sprains, Being surrounded on the upper protection ring 1 of shank position, caused high speed or high acceleration moving can be connected to damping spring 2 thereon therewith The state of approach lock in the short time is formed, it is now upper to form rigid support between the damping spring 2 of protection ring 1 and lower protection ring 3, Upper protection ring 3 can limit the motion positioned at sportsman's shank therein, so as to avoid ankle from being transported in high-speed motion or high acceleration Ankle from sprains caused by dynamic possibility, play the function of protection ankle.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
