Description

A kind of combined type catapult

Technical field

The present invention relates to a kind of sports field of tool of launching, particularly a kind of combined type catapult.

Background technology

Now increasing catapult fan can select to participate in athletic competition, in athletic competition, the use of catapult is had to strict requirement, some match requests are used traditional catapult, and some match requires to use wrist holder bow or card ball catapult, therefore, a catapult can not adapt to the requirement of all athletic competitions, just need entrant to prepare different catapults, in use pretty troublesome, carry also inconvenient.

Summary of the invention

The object of the invention is for solving the problems of the technologies described above, a kind of combined type catapult is provided, the combination of the different assemblies of catapult process changes, and can be combined into the various ways such as traditional catapult, card ball catapult and wrist holder catapult, meets the requirement that different athletic competitions are used catapult.

The present invention is in order to solve the problems of the technologies described above, the technical scheme adopting is: a kind of combined type catapult, comprise bow, bent body and wrist holder, bow is bolted on one end of bent body, the dop of projection is set at the other end of bent body, on the minor axis of wrist holder, deck is set, minor axis rotates in the through hole of deck, to drive wrist holder rotation transformation on diverse location, the draw-in groove corresponding with dop is set on described deck, draw-in groove is connected with through hole, dop can be fastened in draw-in groove, an arc groove is also set on dop as locking slot, the minor axis of described wrist holder is provided with the tight lock part of working in coordination with locking slot, tight lock part partly consists of cambered surface corresponding with draw-in groove position on minor axis, radian and the radius of cambered surface part are consistent with radian and the radius of arc groove inwall on dop, position relative with cambered surface part on minor axis is set to a planar structure, described tight lock part and the locking slot on dop form latch-up structure, to prevent in use wrist holder slippage from bending low.

Described deck both sides arrange respectively a limited post.

Described dop and the cross section of draw-in groove can be set to up-small and down-big shape, for example T font, triangle or trapezoidal.

In order to improve stability and the precision of catapult when shooting, when described bow is fixedly connected with bent body, the bottom of bow link arranges a plurality of projections again, and can insert in the shrinkage pool of bent body relevant position, meanwhile, described projection is non-rectilinear setting on bow, and then to improve the fixing stability of bow, or also can offer one section of holddown groove at bent body and the link of bow, bow is inserted in holddown groove and is fixed, avoid the double swerve of bow.

Described deck below is provided with the fixture in order to priming illumination equipment.

Described bow comprises traditional catapult bow, card ball catapult bow and wrist holder catapult bow, and changes as required.

Described wrist holder has three location status, horizontal level, folding position and use location, wherein, horizontal level is that planar structure on wrist holder minor axis is in level, and the position of wrist holder during over against draw-in groove opening, now the dop of bent body could inject in draw-in groove, then, wrist holder is rotated down 180 degree by horizontal level, the planar structure that makes minor axis is draw-in groove opening dorsad, now wrist holder is in use location, now, wrist holder just in time props up the limited post of deck both sides, the cambered surface part of minor axis is fastened in the arc groove of dop completely, lock the most firm, finally, wrist holder rotates up 90 degree by horizontal level and folds, make short axis plane knot form vertical state, now wrist holder is in folding position, the cambered surface part part of minor axis is fastened in the arc groove of dop, at this moment the volume of catapult is minimum, convenient for collecting and carrying.

The present invention compared with prior art, has following beneficial effect:

First, bow of the present invention, bent body and the wrist holder combination that can break, can change as required satisfactory bow on the one hand, on the other hand, wrist holder and bent body combination are become to wrist holder bow, wrist holder is pulled down and is become handbow from bent body, efficient and convenient, and one can be applicable to the requirement of different match occasions catapult;

Second, in the present invention, the combining structure of wrist holder and bent body is ingenious, coordinating between the locking slot forming with arc groove on dop by the tight lock part that on wrist holder minor axis, cambered surface partly forms, form latch-up structure, make wrist holder at use and folded state, all there will not be the situation of slippage, especially in wrist holder use procedure, solved user and worried that wrist holder comes off or unstable trouble and worry, and this structure do not used screw etc. to be fixedly connected with mode, make the assembly and disassembly of wrist holder simpler, convenient, fast;

The 3rd, deck of the present invention both sides arrange limited post, and when the holder of rotation wrist props up limited post, this position is the use location of wrist holder, and now wrist holder is locked with bent body, by the design of limited post, can in use determine easily the turned position of wrist holder;

The 4th, bow in the present invention is inserted in by projection in the shrinkage pool of bent body and is fixedly connected with bent body, can reduce the use of screw, is convenient to Rapid Combination, and the pulling force that the projection of non-rectilinear setting can avoid bow to be in use subject to rubber band rotates, and then guarantee the precision of shooting;

The 5th, the present invention can also be fixedly installed lighting apparatus below deck, to facilitate the use at night.
