Abstract
The utility model provides a shifted diving board used for a diving sport, comprising a diving board. The shifted diving board is characterized in that: the shifted diving board is also provided a shifted driving device which can make the front end of the diving board shift. The shifted driving device is mounted on the lower end of the diving board, and the top surface of the shifted driving device is connected with the diving board. The shifted driving device can be a reciprocating motion device in which a hydraulic oil cylinder is used as a main part, and also can be a left and right rotary device which is assembled by a hydraulic rotary motor or a hydraulic oil cylinder, a rack, and a gear. The utility model can realize the fore-and-aft or right and left shift of the front end of the diving board. The absolute safe of a diving athlete is ensured by the shift of the diving board after the diving athlete departs from the diving board, and the accident of the collision of the diving board and the diving athlete is efficiently avoided.
Description
Affiliated technical field
The utility model relates to sports equipment, particularly a kind of diving displacement springboard.
Background technology
In the prior art, the employed springboard of diving can not be done elastic and the displacement that swings, and this fixed springboard is a constant with respect to the distance along the coordinate that hangs down, and promptly immobilizes.And the diver bounces up and down in training and competition when falling, and whereabouts line coordinates value is parameter, and its health is meeting and springboard collision unavoidably, causes player injuries, and this accident occurred in worldwide match.Therefore, the springboard of this traditional type is for match or training, and shortage is perfectly safe, and this is the prior art weak point just.
Summary of the invention
In order to solve the problem that existing springboard can not be perfectly safe, the utility model provides a kind of and can not touch displacement before the springboard as yet after the diver takeoffs, and definitely guarantees the diving displacement springboard of sports safety.
Above-mentioned task realizes by this way: a kind of diving displacement springboard, comprise a springboard, and it is characterized in that also having a displacement drive unit that allows the front edge of board displacement, this displacement drive unit is placed in the springboard lower end, and its end face is connected with springboard.
Described displacement drive unit is made up of connecting plate, hydraulic jack, gear, upper rack, following tooth bar and base, hydraulic jack is placed on the base, gear is installed on the gear shaft of hydraulic cylinder piston rod front end, be placed in respectively on base and the connecting plate with the following tooth bar and the upper rack of gears engaged, springboard is installed on the connecting plate.The technical program is by hydraulic jack driven wheel scroll forward and backward, because tooth bar is fixed down, makes upper rack drive springboard by connecting plate and moves forward and backward, and produces displacement.Therefore, in use, after the diver jumped out of springboard, the coach manually controlled or by optoelectronic induction control springboard is moved immediately backward, and the accident that can avoid the diver to collide springboard takes place.
Described displacement drive unit is by connecting plate, the hydraulic gyration motor, and base is formed, and the hydraulic gyration motor is placed on the base, and its upper end is connected with connecting plate, and springboard is placed on the connecting plate.In order to improve the rotating stability of springboard, can on the base in hydraulic gyration motor the place ahead, establish a circular guideway, on connecting plate, be provided with a guide wheel that cooperates with circular guideway.The technical program is that the revolution by the hydraulic gyration motor makes front edge of board produce left and right sides displacement, can avoid the generation of aforementioned accident equally.
Described displacement drive unit can also be made up of connecting plate, gear, tooth bar, hydraulic jack and base, gear passes through its gear shaft horizontal setting on the bearing block of base, the upper end of gear shaft is connected with connecting plate, hydraulic jack is installed on the base, be connected with the piston rod of hydraulic jack with the tooth bar of gears engaged, springboard is placed on the connecting plate.In order to strengthen the rotating stability of springboard, also a circular guideway can be set on the base in gear the place ahead, on connecting plate, be provided with a guide wheel that cooperates with circular guideway.This programme is to seesaw by hydraulic jack driving tooth bar to turn round about driven gear, and the front edge of board generation left and right sides displacement that makes it and be connected achieves the above object equally.
In sum, the utility model is to make the front edge of board displacement by the displacement drive unit, avoids diver's whereabouts track, thereby prevents the generation of collision accident effectively.In addition, the utility model also has advantages such as simple in structure, easy to operate and safe and reliable, is worthy of popularization.
