Abstract
The utility model relates to sports goods, a accurate catapult that aims specifically says so. Include the handle and install the bow body in the handle upper end, be provided with the rubber band on the bow body, the centre of rubber band is provided with the bullet pocket, two bracing pieces are installed to the lower extreme symmetry of handle, and the both ends of the bow body set up there is the pulley respectively, pulley fixed connection is walked around respectively on the bracing piece in the both ends of rubber band. This accurate catapult that aims adopts longer rubber band and helping hand bracing piece, is favorable to improving launching the distance, adopts the rotatable bow body to be favorable to keeping the bow body perpendicular with the aiming line simultaneously, improves the accuracy of fire.
Description
Technical field
This utility model relates to a kind of sports goods, the catapult of a kind of accurate aiming.
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 rubber band is fastened at the two ends of bow body, and the centre of rubber band is with the bullet pocket of parcel bullet.The power of catapult depends on elastic force and the length of rubber band, but is limited owing to being opened up by human body arm, and the length of rubber band can not indefinite extension；On the other hand being limited by human body arm strength, the elastic force of rubber band is also impossible to infinitely strengthen.Additionally, play pocket and be arranged on the centre position of rubber band, use and middle require that the bow body of catapult is vertical with aiming line, otherwise easily cause the rubber band elastic force imbalance playing pocket both sides, the bullet deviation aiming line of injection, but the bow body of common catapult uses fixing connection with handle, using and be difficult to keep bow body vertical with aiming line, the accuracy of shooting is affected.
Summary of the invention
The catapult precisely aimed at that the purpose of this utility model is to provide that a kind of elastic force is big, to launch accuracy high, easy to use.
This utility model be the technical scheme is that by solving technical problem
The catapult of a kind of accurate aiming described in the utility model includes handle and is arranged on the bow body of handle upper end, it is provided with rubber band on bow body, the centre of described rubber band is provided with bullet pocket, the upper end thereof of described bow body have can pitching deflection sight, the end of described rubber band is fixedly connected on sight.
The centre of described bow body is fixedly connected with rotating shaft, and described rotating shaft is rotatably inserted into the upper end of handle.
The upper end of described bow body is fixing connects horizontally disposed hinge, described sight is rectangular plate-like structure, it is provided for installing the axis hole of hinge on the axis of described rectangular slab, the front projection of axial notch it is provided with on the rectangular slab in described axis hole front, being provided with the rear projection of isosceles triangle scale on the rectangular slab at axis hole rear, rubber band is fixedly connected on the rectangular slab at axis hole rear.
The center of described handle is rotatably mounted with axis, and the centre of bow body is fixedly connected on the upper end of axis, and the lower end of axis is fixing connects two support bars, and described support bar is sheet elastomers, and the angle between two support bars is 180 degree；The upper end of described bow body is fixed with pulley yoke, is provided with pulley in described pulley yoke, and the other end separately having one end to be connected to play the elastic force rubber band on pocket is walked around pulley and is fixedly connected on support bar.
Owing to have employed said structure, this catapult precisely aimed at uses longer rubber band and power assisted support rod, is conducive to improving catapulting distance, uses rotatable bow body to be conducive to keeping bow body vertical with aiming line simultaneously, and sight can improve the accuracy of fire.

Fig. 2 is the planar structure schematic diagram of sight.
Fig. 3 is the structural representation of another embodiment of this utility model.
Detailed description of the invention
As shown in Figure 1, the catapult of a kind of accurate aiming described in the utility model includes handle 1 and is arranged on the bow body 2 of handle upper end, it is provided with rubber band 3 on bow body 2, the centre of described rubber band 3 is provided with bullet pocket 4, the upper end thereof of described bow body 2 have can pitching deflection sight 21,22, the end of described rubber band 3 is fixedly connected on sight 21,22.During use, the when of tension rubber band 3, sight 21,22 can improve, with rubber band 3 pitching, the precision aimed at.
The centre of described bow body 2 is fixedly connected with rotating shaft, and described rotating shaft is rotatably inserted into the upper end of handle 1.The when of tension rubber band 3, bow body 2 can swing with rubber band 3, remains vertical with aiming line, it is to avoid bullet is penetrated partially.
The upper end of described bow body 2 is fixing connects horizontally disposed hinge, as shown in Figure 2, described sight 21,22 is rectangular plate-like structure, it is provided for installing the axis hole 23 of hinge on the axis of described rectangular slab, it is provided with the front projection 24 of axial notch on the rectangular slab in described axis hole 23 front, the rectangular slab at axis hole 23 rear is provided with the rear projection 25 of isosceles triangle scale；Rubber band 3 is fixedly connected on the rectangular slab at axis hole 23 rear.During aiming, sight line groove and target three by the triangle scale of rear projection 25, through front projection 24 forms straight line, i.e. represents and has aimed at target.
As shown in Figure 3, another embodiment of the present utility model, the center of described handle 1 is rotatably mounted with axis, the centre of bow body 2 is fixedly connected on the upper end of axis, the lower end of axis is fixing connects two support bars 5,6, described support bar 5,6 can be rigid rodlike, it is also possible to be sheet elastomers, and the angle between two support bars 5,6 is 180 degree；The upper end of described bow body 2 is fixed with pulley yoke, is provided with pulley 7,8 in described pulley yoke, and the other end separately having one end to be connected to play the elastic force rubber band 31 on pocket 4 is walked around pulley 7,8 and is fixedly connected on support bar 5,6.Longer elastic force rubber band 31 so can be used to reach to improve the purpose of elastic force.
