The utility model is mainly provided with a safety adjusting part corresponding to a wheel body; the braking tightening degree between the safety device and the wheel body is changed by the safety adjusting part, which can lead the wheel body of the wheel shoe and sliding plate to be carried out from fully stopping to fully releasing and from stop positioning to reducing to fully opening without reducing speed; when stopping positioning, the utility model has high safety; when reducing the speed, the utility model can provide best safety speed or fully releases; the utility model can be changed according to the different requirements of the user, and has the efficacies of pre-adjustment, high safety and high stability.
Description
Technical field
The utility model is a kind of safety device of taking turns footwear and slide plate, wheel body side by wheel footwear and slide plate is oppositely arranged safety device, can do relative adjustment according to the needs on individual or the environment for the user, to reach the purpose of high flexibility, high security and high stability.
Background technology
The safeguard construction of present user in ice skate is that rear end or the front end in the footwear body is provided with a brake shoes mostly, and so structure has following defective in fact when using:
1, security is low, must be dependent on advanced technology, the user is when safety, when if footwear body rear end is provided with the structure of brake shoes, must be that fulcrum is suppressed brake shoes downwards with the wheel body of heel with foot, make brake shoes and ground applying safety, if and footwear body front end is provided with brake shoes, then must be that fulcrum is to sinciput with the wheel body of foot's front end, brake shoes can be slowed down with ground friction, so the mode action that must rely in user's motion is reached, and the user can't set before motion or adjust at once, for the beginner, be difficult to utilization in fact, even when standing, still have the state that can't stand really, its structure to be difficult to bring into play its due effect, often the user is caused improper falling because of its excessive velocities, the accident that meets accident, not only cause unnecessary athletic injury, more cause unnecessary setback in study, and influence the power and the effect of follow-up exercise.
The degree of the grasp brake safety that 2, the beginner can't be certain, for the beginner, the sports equipment of general wheel body is when sliding, its speed very fast, the brake that Chang Wufa is certain, and, because it is too fast that its sliding speed is quickened, especially when the state of descending, the user more is difficult to control, so necessity of improvement is arranged.
Structural form with regard to scooter, it is before slide plate, be pivoted with one group of wheel body on the rear end respectively, front-wheel is controlled by the leader, and the structure of brake directly is provided with the brake structure that can trample mostly in the top of trailing wheel, because its brake structure is to be set as directly to trample with pin for the user, so these structural designs, can't apply to aforesaid the wheel on the footwear structure, and, more can't be referenced to the skateboard in the general extreme sport, because of the structure of its slide plate, be to be provided with two relative wheel body structural forms in the slide plate bottom, wheel body can't be by the control of slide plate top, so also can't be used for this skateboard, so the function that slide plate will obtain to brake with regard to present structural form, can't be reached in fact.
No. 89206420, the brake structure of scooter such as utility model patent, mention its brake structure in " scooter trailing wheel anti-vibration structure ", brake bracket action control bit dish with U type, to cooperate control to be subjected to Moving plate and shell fragment and brake member, brake member can after trampling brake bracket, the user be moved, with the clamping wheel body, its major defect is:
Because it is directly to trample control structure by the user, therefore, overall structure also can't apply to take turns brake on footwear or the slide plate, and the form person of being to use of this brake controls, and the form of positive brake can't be provided, therefore, when apply the brakes not, scooter the form of the high speed slippage of not braking, so when user's technology is unskillful as yet, the i.e. danger of ten minutes in the use is so also there is necessity of its improvement.
The inventor makes the wheel footwear preestablish different safety shut-down degree with slide plate, do different settings in order to needs on the various environment and the different user's demand of various degree, to reach high security, high interesting and high controlled purpose, create the technical solution of the utility model.
Summary of the invention
