According to the boosting type slingshot provided by the invention, the moment of the rubber band is adjusted by adopting the eccentric wheels, and the boosting type slingshot is compact in structure and strong in manipulation performance; and with the adoption of the horizontally rotary slingshot body, the slingshot body can keep vertical with an alignment line and elastic force of the rubber band on the two sides of the shot bag is balanced, so that the shooting accuracy is improved.
Description
Technical field
The present invention relates to a kind of sports goods, it is a kind of eccentric booster type catapult specifically.
Background technology
Catapult is a kind of conventional physical culture, game articles, and common catapult is made up of the bow body of a Y shape, and bungee is fastened at the two ends of bow body, and the centre of bungee is with the bullet pocket of parcel bullet. The power of catapult depends on elastic force and the length of bungee, but owing to being subject to the restriction of human body arm exhibition, the impossible indefinite extension of the length of bungee, the length that bungee is stretched is directly proportional to elastic force, and when limit of stretch, arm is relatively big by power, normal with shake, it is unfavorable for aiming at, after release plays pocket, the impellent playing pocket is sharply reduced by bungee, and these factors are all unfavorable for accurate shooting. In addition, play the mid-way that pocket is arranged on bungee, use and middle require that the bow body of catapult is vertical with hair-line(crack), otherwise easily cause the bungee elastic force playing pocket both sides uneven, the bullet deviation hair-line(crack) of injection, but the bow body of common catapult adopts with handle and is fixedly connected with, it may also be useful to being difficult to keep bow body vertical with hair-line(crack), the accuracy of shooting is affected.
Summary of the invention
It is an object of the invention to provide a kind of elastic force big, launch accuracy height, eccentric booster type catapult easy to use.
The present invention is the technical scheme that technical solution problem adopts:
Eccentric booster type catapult of the present invention comprises handle and is arranged on the bow body of handle upper end, described bow body comprises symmetrically arranged left bow body and right bow body, the lower end of described left bow body and right bow body is fixed together by bow body connecting rod, bow body is provided with bungee, the centre of described bungee is provided with bullet pocket, the lower section of described left bow body and right bow body is separately installed with eccentric wheel by hinge, the upper end of left bow body and right bow body is separately installed with pulley, and the end of bungee is walked around pulley and is connected on eccentric wheel.
The peripheral zone of described eccentric wheel has wire casing, and described hinge is positioned at the eccentric position of eccentric wheel.
Being provided with the roller bearing for reducing frictional coefficient in the wire casing of eccentric wheel, the end of described bungee is walked around wire casing and is fixedly connected on hinge.
Described bow body comprises the lower end being fixedly connected on left bow body and right bow body and the hinge support extended downwards, and described hinge is rotatably inserted on hinge support.
The lower end of described hinge support is fixedly connected with the lower end of handle by union lever.
Same hinge runs through the both sides being inserted into hinge support simultaneously, and eccentric wheel is fixedly connected on the two ends of hinge, is provided with torsion spring between described hinge and bow body.
Slide and be set with sliding cover in the outside of described handle.
Described bow body is provided with locating point, between described locating point and corresponding eccentric wheel, is provided with elastomerics.
Owing to have employed said structure, this power-assisted bullet is ingenious utilizes the deflection of eccentric wheel to change moment when bungee stretches, make the stage casing of stretching bigger by power, that suitably reduces limit of stretch state is subject to power, alleviating the load of arm, be conducive to accurate aiming, release can obtain the thrust of long period after playing pocket, contribute to bullet to keep running orbit, extend shooting distance, improve shooting accuracy; Its compact construction, handling are strong; The bow body that can horizontally rotate is conducive to keeping the elastic force that bow body is vertical with hair-line(crack), balance plays pocket both sides bungee, it is to increase shooting accuracy.

Embodiment
As shown in Figure 1, eccentric booster type catapult of the present invention comprises handle 1 and is arranged on the bow body 2 of handle upper end, described bow body 2 comprises symmetrically arranged left bow body 21 and right bow body 22, the lower end of described left bow body 21 and right bow body 22 is fixed together by bow body connecting rod 23, bow body 2 is provided with bungee 3, the centre of described bungee 3 is provided with and plays pocket 4, the side of described left bow body 21 and right bow body 22 is separately installed with eccentric wheel 5 by hinge, the upper end of left bow body 21 and right bow body 22 is separately installed with pulley 6, such as Fig. 3, shown in Fig. 4, the end of bungee 3 is walked around pulley 6 and is connected on eccentric wheel 5.
As shown in Figure 5, the peripheral zone of this eccentric wheel 5 has wire casing, and described hinge is positioned at the eccentric position of eccentric wheel. As shown in Figure 6, being provided with the roller bearing 51 for reducing frictional coefficient in the wire casing of eccentric wheel 5 eccentric wheel, the end of described bungee 3 is walked around wire casing and is fixedly connected on hinge.
