Summary of the invention

The purpose of the utility model provides a kind of brake gear of skate, and the brake lining and the friction between the ground of heel brake that overcomes present skate is less, the deficiency that can't check fast.

The utility model is achieved through following technical proposals.

The utility model comprises footwear and connected framework and is loaded on pulley and the heel brake on the said framework; Be provided with at least the groove of stopping of leading corresponding to a said pulley; The said groove of stopping of leading fixedly is loaded on the said framework and has distance ground to be surrounded on preceding, the last and rear of corresponding said pulley; Said leading in the groove of stopping can be equipped with the sheet of stopping slidingly back and forth, and the said sheet of stopping is made up of anter, cauda and the linkage section that connects them, and said anter and cauda have part to stretch in respectively saidly to lead in the groove of stopping, part stretches out in said leading outside the groove of stopping; The end face of said cauda is lower than the attrition surface over the ground of said heel brake, in the outer end of said cauda block is housed; Said stop sheet and said lead to stop the maintaining body that resets is housed between the groove.As long as there is a very little power to advance said cauda to said the inside of leading the groove of stopping, then said anter will stretch out downwards, brought between the said pulley and ground of its back behind the tread surface; Because said block retaining is at said notch of leading the groove of stopping; Said anter can not be protracted again; Can only closely fit in said pulley and also and between the ground carry out sliding friction, at this moment, might concentrate on the pedal force of very big part on the said anter fully; Make to produce bigger frictional force between itself and the ground, to reach the purpose of stopping fast and stopping.

The utility model is in order to make said cauda when promoting said anter through said linkage section; Let said linkage section at the said resistance of to reduce friction when moving in the groove of stopping of leading; Said slide plate outside and said lead to stop a plurality of balls are housed between the groove inner face; Perhaps, the roller chain of said linkage section for dressing up by a plurality of group of rollers.The effect of the said maintaining body that resets is after brake is accomplished, removed pressure to said anter after, can make said anter withdrawal, said cauda stretches out and keep usual state; The said maintaining body that resets is to be loaded on said anter and said to lead the extension spring of stopping between the groove; Also can, the said maintaining body that resets is to be loaded on said back sheet and the said spring of stopping between the groove of leading.

Against existing technologies, the beneficial effect of the utility model is:

Can make skate in brake process, obtain the frictional force between bigger and the ground, stop, help the generation of the accident of stopping thereby stop quickly.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.

The utility model is led the groove 5 of stopping and can be adopted sheet metal to process, and also available engineering plastics are processed, owing to the time can receive bigger push-pull effort in brake, so sufficient intensity will be arranged itself and will be connected firmly with framework 2.Anter 7 can be used the sheet material of semihard, should be anti-draw wear-resisting wiping, and its front end should do wedgewise, and cauda 8 can be used thicker harder bar material.When implementing braking, set the utility model and heel brake 4 and all be loaded on the skate of right crus of diaphragm, skidding person mainly is put in left side foot to center of gravity earlier; Reach out right foot slightly, mention the tiptoe of right foot then, at this moment; Cauda 8 is at first run into the 5 li indentations of groove of stopping of ground and guide, releases anter 7 through linkage section 9 simultaneously, wears between thereafter pulley 3 and ground anter 7 quilts; Because link stopper 10 blocks at the notch of leading the groove 5 of stopping, anter 7 can't stretch out again, can only block motionless; The brake lining of heel brake at this moment 4 contacts with ground, produces certain frictional force, and the speed of skate is decreased.Skidding person moves on to right foot with center of gravity then, and imposes on bigger pedal force on the pulley 3 that is blocked by anter 7, and pulley 3 suffered pedal forces are passed to anter 7 immediately, make the bigger frictional resistance of generation between anter 7 and the ground, check skate fast.Stop stop after, as long as lift right foot slightly, the pressure on the anter 7 disappears because the effect of extension spring 14 (or spring 15), anter 7 withdrawals, cauda 8 stretches out simultaneously, recovers and remains in state at ordinary times.
