Description

Suspension bracket type returned ball accelerator

Technical field

The utility model belongs to the sporting equipment field, relates to a kind of suspension bracket type returned ball accelerator in the bowling equipment.

Background technology

In the prior art, " the horizontal returned ball accelerator of a kind of car formula " in the disclosed bowling equipment of Chinese patent ZL012298115 has advantageous superiority, and be simple in structure, installation, adjusting, easy to maintenance, and the return of serve acceleration is good, but still exists not enough.The one, install, when maintenance or whole the replacement, must carry out from being pulled outwardly out between adjacent two blocks of wallboards of adjacent two alleys, and for existing alley, the electric instrument control cabinet and the instrument board of complete machine all are housed at the position, termination between adjacent two blocks of wallboards of adjacent two alleys, thereby bring a lot of troubles to outwards pulling out the horizontal returned ball accelerator of car formula, when especially the returning accelerator of old alley being transformed, also therefore exist the horizontal returned ball accelerator of car formula and be difficult for carrying out the problem that harmony is regulated with the independent goal that is provided with, the 2nd, free and regulate automatically that to quicken roller unreasonable to the pressure of the ball that returned to pay the stage clip that is equipped with between frame and the body frame, because the telescopic displacement of stage clip is bigger, and the two ends of stage clip all are positioned at body frame with radial type and pay on the frame, in service, mutual wearing and tearing will inevitably make the gap between the articulated elements increasing between the articulated elements, therefore, can be directly influence quicken the pressure of roller to the ball that returned, and difficult adjusting, thus influence return of serve speed.

Summary of the invention

The technical problem that solves:

A kind of suspension bracket type returned ball accelerator is provided, it mainly is improvement to Chinese patent ZL012298115, can overcome the deficiencies in the prior art, it is very convenient when installation, adjusting, maintenance or globality are replaced, more favourable when especially the returning accelerator of old alley being transformed, with the independent goal that is provided with, be easy to carry out harmony and regulate, and can make and quicken that roller is convenient to regulate to the pressure of the ball that returned and stable, thereby assurance return of serve speed.

The technical scheme that adopts:

Suspension bracket type returned ball accelerator, has body frame, by big rotating shaft and the hinged subframe of body frame, be to have the acceleration roller in the transmission system at center with the motor, a whole set of transmission system all is contained on the subframe, transmission system between motor and the acceleration roller, by the motor drive, quicken roller drive and supporting driving-belt composition, and has an adjusting device of driving-belt, also have and quicken the pressure-regulating device of roller the ball that returned, it is characterized in that: body frame is a nose suspension type, has top board, and the rear end formula of hanging upside down of top board is equipped with after gallows, the bottom of after gallows and the rear end of subframe are hinged by big rotating shaft, the front end formula of hanging upside down of top board is equipped with front hanger, and the bottom of front hanger is by the articulated adjusting screw(rod) of little axle, and adjusting screw(rod) is adjustable detachable again property to link together with front end subframe; Described returned ball accelerator, by the adjustable detachable again property in top board globality ground be contained on the wallboard.

Beneficial effect:

Suspension bracket type returned ball accelerator, by the adjustable detachable again property in top board globality ground be contained on the top end face of wallboard of alley, there are enough activity spaces at the position on this top end face, can upwards take out to globality accelerator, it is very convenient when therefore installation, adjusting, maintenance and globality are replaced, more favourable when especially old alley returning accelerator being transformed, be easy to supporting with the independent goal that is provided with and carry out harmony and regulate; Can make and quicken the pressure stability of roller, and regulate easily the ball that returned, thus assurance return of serve speed; While compact conformation, light.
