Abstract

A ball clamping slingshot capable of being stretched in multiple directions mainly comprises a slingshot frame, runners and rotating shafts, wherein the runners are arranged at the upper ends of two arms of the slingshot frame, and an original rubber band with a clamping ball fixed on the arm of the slingshot is installed on the runners; the rotating shaft is fixed on the two sides of the runner; and the rotating shafts are arranged in round holes at the upper ends of the two arms of the slingshot frame in a movable matching way, so that the runners and the rotating shafts can rotate on the two arms of the slingshot frame synchronously. Therefore, the runners can be driven to turn front and back by pulling the rubber band in different directions, and the rubber band is kept at a normal tension state throughout, thereby avoiding the sharp bending of the rubber band and prolonging the service life of the rubber band. Therefore, the ball clamping slingshot has the advantage of turning flexibility of a rubber band of a traditional slingshot, and keeps the advantage of convenient installation of the rubber band of the original ball clamping slingshot.

Description

But the ball card catapult of multi tension

Affiliated field

The utility model relates to a kind of sports field of tool of launching, particularly a kind of ball card catapult.

Background technology

Common catapult comes point to mainly contain two kinds in traditional catapult and ball card catapult by design feature, and their planform basically all is Y shapes, and two catapult arms that separate with tree V shape appearance are arranged above handle.The elastic rubber band adhesive tape of these two kinds of catapults all is the two catapult arm tops that are connected the handle shelf, and its method for using is to hold handle with one, and the another hand pinches rubber band bullet pocket backward directions and draws, the release hoodle of loosing one's grip then, directive target object.

Ball card catapult is that the rubber band that end is equipped with the card ball is penetrated in the shoulder hole (card ball hole) on the catapult arm; Utilizing the card ball to be blocked in the shoulder hole then fixes rubber band; And sharply bending wearing and tearing can take place with the shoulder hole edge in fixing rubber band in the different directions drawing process, and rubber band breakage occurs easily in the installation place of catapult arm.Simultaneously, fixing rubber band is restricted draw direction, also will distinguish the positive and negative of catapult in use earlier; Cumbersome time-consuming; The posture of shaking hands at parting that this has also limited the user lets the people feel awkward, uncomfortable, does not also have as traditional catapult the flexibility of rubber band towards multi-direction stretching.

The utility model content

In order to solve easy to wear, the shortcoming that can only orientation stretching of above-mentioned ball card catapult rubber band; Under the prerequisite of emission function that does not change catapult and launching effect; But the utility model provides a kind of ball card catapult of multi tension, has increased the polytropism that rubber band stretches, and has prolonged the service life of rubber band.

The technical scheme that the utility model is taked is: but a kind of ball card catapult of multi tension mainly comprises catapult frame, runner and rotating shaft.It is characterized in that: runner is installed in the upper end at catapult frame two arms, and the former rubber band that is secured in band card ball on the bow arm is installed on this runner; The both sides of runner are fixed with rotating shaft, and rotating shaft is installed in the circular hole of catapult frame two arms upper end with mode movingly, make runner and the rotating shaft can rotation synchronously on catapult frame two arms.Like this, just can drive runner towards different directions pulling rubber band and realize the front and back upset, and rubber band is in normal extended state all the time, avoids taking place rapid bending.

The beneficial effect of the utility model is: make that through the runner that is installed in catapult frame two arms upper ends the rubber band of ball card catapult can multi tension; The rubber band flexible overturning property that had both had the tradition bow; The advantage that kept original ball card catapult rubber band to be convenient to install has again also overcome rubber band and has occurred the shortcoming of wearing and tearing in the installation place of catapult arm easily.Simultaneously, this runner relatively simple for structure, handling ease has also had good value economically.

Among the figure: 1. catapult frame 2. runners 3. rotating shafts 4. rubber bands 5. block balls 6. shoulder holes 7. grooves.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 1, the ball card catapult that the utility model provides mainly comprises catapult frame 1, runner 2 and rotating shaft 3; Wherein, rotating shaft 3 is installed in the circular hole of 1 liang of arm of catapult frame with mode movingly, and the upper end that runner 2 is arranged in 1 liang of arm of catapult frame is provided with open slot; Rotating shaft 3 is fixed on the both sides of runner 2, makes wheel 2 and axle 3 can on 1 liang of arm of catapult frame, keep rotating synchronously.

As shown in Figure 2, have the shoulder hole 6 of two symmetries in the runner 2, the outside in hole 6 has groove 7.

As shown in Figure 3, after an end of rubber band 4 is put into card ball 5, pack rubber band 4 shoulder hole 6 of runner 2 into together with card ball 5 along groove 7.Because the diameter of card ball 5 equals the big bore dia of shoulder hole in the runner 2, when suitably straining rubber band 4 to the right, card ball 5 is stuck in by rubber band 4 in the shoulder hole of runner 2, then rubber band 4 is fixed in the shoulder hole 6 of runner 2.

As shown in Figure 4; Because runner 2 can rotate in 1 liang of arm of shelf with rotating shaft 3; Pulling rubber band 4 can drive runner 2 and rotates in 180 degree scopes by the direction shown in the arrow, thereby it is more flexible that rubber band is stretched, and has also reduced the degree of wear that rubber band receives the shoulder hole edge simultaneously.

The above is used for the utility model, but is not used in the scope that limits the utility model.Under the prerequisite that does not break away from the utility model know-why, the utility model can also be done some variations and variation, and these modifications and variation also are regarded as the protection domain of the utility model.
