Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
See accompanying drawing 1-3, this novel disclosed this acrobatic roller skating training protector, comprises horizontal drag-line 1, automatic tightening device 2, suspender belt 3, the helmet 5 and shoulder belt 6.Horizontal drag-line 1 is horizontally disposed with, its two ends are fixed on building, the steel wire rope of this horizontal drag-line preferred diameter 11mm load 2000kg, model is GB-1102(1+6+12+18), its two ends are fixed on the high constructure or vertical rod of ground 2.5m, and are about the cableway of about 10-15m by spooler tension formation one.Automatic tightening device 2 is lifted on horizontal drag-line 1, and suspender belt is flexibly connected with the helmet 5 by movable pulley 4, and shoulder belt 6 is fixed on the both sides of the helmet, during use, the helmet is worn on sportsman's head, and athletic upper limbs is through shoulder belt, shoulder belt is jack type accommodation zone, regulates its length according to actual needs.
Automatic tightening device comprises cableway pulley 7, tape feed roller and automatic tightening device support 10.Automatic tightening device support comprises the plate body of two class trapezium structures, the upper end of two plate bodys is connected with the two axial ends of cableway pulley 7 respectively, its lower end is connected with Belt-coiling wheel shaft, tape feed roller comprises the active tape feed roller 9 and driven tape feed roller 8 that are set up in parallel, initiatively tape feed roller and driven tape feed roller comprise the reel of integrative-structure, Belt-coiling wheel shaft respectively and are arranged on the gear at reel two ends, i.e. initiatively tape feed roller reel 18 and driven tape feed roller reel 19.One group of gear initiatively in tape feed roller respectively with group meshed transmission gear of in driven tape feed roller; Suspender belt 3 inflection takes the shape of the letter U structure, and its two free ends install around respectively in the same way on the reel of active tape feed roller and driven tape feed roller.Initiatively the axle head of tape feed roller 9 and driven tape feed roller 8 is respectively arranged with take-up clockwork spring 12, each take-up clockwork spring is around on Belt-coiling wheel shaft, take-up clockwork spring 12 outer cover is equipped with take-up going barrel 11, the effect of take-up clockwork spring is exactly play the effect of tightening up suspender belt to two tape feed rollers, identical with action of reset spring.The middle part of suspender belt is sleeved on the upper of movable pulley 4, movable pulley axle 13 two ends are flexibly connected with the two ends of moving pulley bracket 15 respectively, moving pulley bracket 15 is fixedly connected with a pivot pin 16 by fastening locknut 14, the bottom of this pivot pin 16 is flexibly connected with the bearing 17 being arranged on the helmet 5 top, like this, sportsman can realize the actions such as original place rotation with the helmet.
Automatic tightening device is the core of this protector, and it can realize the function of automatic band-retracting and slow releasing suspender belt, plays the effect of safeguard protection.Gear initiatively in tape feed roller and the gear in driven tape feed roller are 1:1 engaged transmission; Initiatively the outside barrel diameter of tape feed roller is 2 times of driven tape feed roller outside barrel diameter.
The convergent-divergent principle of the automatic tightening device of this training protector: when sportsman normally trains, movable pulley is not by downward pulling force, take-up clockwork spring reverses initiatively tape feed roller and rotates clockwise under the effect of self Curl power, gear 1:1 engaged transmission initiatively in tape feed roller and driven tape feed roller, driven tape feed roller rotates counterclockwise, suspender belt is wound around in the same way on the reel of two-wheeled, but because the outside barrel diameter of active tape feed roller is larger than driven tape feed roller outside barrel diameter, therefore, two reels are when rotating speed is identical, the suspender belt that the suspender belt that initiatively tape feed roller end is wound around is wound around than driven tape feed roller end is many, namely receive to be greater than and put, suspender belt is in the state of tightening up, when sportsman will fall, movable pulley is by downward pulling force, due to the gear 1:1 engaged transmission in active tape feed roller and driven tape feed roller, initiatively the outside barrel diameter of tape feed roller is larger than driven tape feed roller outside barrel diameter, therefore initiatively suffered by tape feed roller, rotating torque is greater than driven tape feed roller, initiatively tape feed roller reel rotates counterclockwise release suspender belt, driven tape feed roller reel rotates clockwise and tightens up suspender belt, two reels are when rotating speed is identical, it is many that the suspender belt that initiatively tape feed roller end is wound around puts band than driven tape feed roller end, namely amplify in receipts, suspender belt is in release conditions, the movable pulley be sleeved on suspender belt presents slow falling, play health and ground when Protection of the sportsman is fallen down not collide, simultaneously suspender belt slow falls and to alleviate when falling down shoulder belt to the damage of health.
