Abstract

A quick-shooting primary coach crossbow solves the problems that the traditional bow and arrow crossbow is still in a laborious bow pulling state during aiming, the hit rate is low and the like. The main technical characteristics are as follows: when the upper gun body moves forwards and inclines relative to the lower gun body, the bowstring sleeved on the lower gun body is fixed in the upper gun body arrow triggering groove; when the upper gun body is pulled back to the original position by moving the rod, the bowstring is pulled away, and finally the trigger is pulled to launch the arrow. The utility model has the advantages of simple structure, convenient transmission, high hit rate, continuous transmission and the like.

Description

Rapid-shooting crossbow for training use

The utility model relates to the rapid fire device, the elementary coach's crossbow of especially a kind of rapid fire.

Traditional bow and arrow needs with pulling bow, the effort of pulling the bow, and the degree of accuracy is difficult for improving, and can only the single-shot emission.The utility model purpose is: at the deficiency that existing bow and arrow exists, design a kind of simple in structure, pull the bow joint power, convenience, and the rapid fire that shoots straight religion joins crossbow.

The utility model is achieved in that it is integrated the bow and arrow and the body of a gun, and utilize lever principle that bow is drawn back, collude the trigger action emission after the aiming again, its primary structure is: be positioned at the bow that lower gun body is worn the bow hole, its string places in the bow and arrow slip through hole of upper gun body; Between the upper and lower body of a gun by move bar in, following two axle axles are moving links to each other, and an arrow box that is communicated with bow and arrow slip through hole are set on upper gun body.When moving bar and promote forward, the relative lower gun body of upper gun body moves forward and tilts, and makes bow and arrow fall into the constant chord position of upper gun body, will move bar then and pull back, and this moment, string was drawn, and the upper and lower body of a gun is parallel.Collude trigger action at last and trigger the constant chord of upper gun body, string is launched the arrow that bow and arrow slides in the through-hole groove.

The utlity model has simple in structurely, easy to operate, pull the bow and the run-home segmentation is carried out, can improve hit rate greatly.But not only running fire archery, but also can or replace arrow shaft with the metal ball, make the one arrow mix pilosity.Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail.

Fig. 1 is the pull the bow surface structure schematic diagram of state of the utility model.

Fig. 2 is the surface structure schematic diagram of the aiming state of the utility model after pulling the bow.

In Fig. 1,2,1, gun barrel, 2, foresight, 3, upper gun body, 4, arrow lid turning cylinder, 5, arrow lid, 6, dress arrow inlet, 7, arrow shaft, 8, handle, 9, bow, 10, string, 11, move bar, 12, arrow box, 13, postive stop baffle, 14, bow and arrow slip through hole, 15, wear bow hole, 16, lower gun body, 17, upper gun body arrow trigger bellmouth, 18, upper gun body axle, 19, cone pin, 20, lower gun body axle, 21, lower gun body bellmouth, 22, trigger axle, 23, guard ring, 24, trigger, 25, trigger triggering sheet, 26, gun stock, 27, arrow groove.In this embodiment: (1) upper gun body position: the top of bow and arrow slip through hole 14 is communicated with arrow box 12, its below, and at afterbody arrow is set also and triggers bellmouth 17; (2) lower gun body position: the cone pin 19 corresponding lower gun body bellmouths 21 above lower gun body 16 in one of design and the arrow triggering bellmouth 17.

In conjunction with the use of above-mentioned description of drawings the utility model.

At first will move bar 11 pushes away forward, making string 10 fall into arrow triggers in the hole 17 (as shown in Figure 1), secondly will move bar pulls back (as shown in Figure 2), and from entering the mouth 6 to pack into the metal ball of some arrow shaft 7(or some of arrow box 12), the lowermost arrow shafts (or layer of metal ball) in the arrow box 12 are fallen in the arrow groove 27; At last, aim at and collude trigger action 24, the cone pins 19 that triggering sheet 25 will be inserted in the bellmouth 21 move up, and this pin lifts string 10, the arrow shafts (or metal ball) in the arrow groove 27 is launched by the body of a gun 1, thereby reached the utility model purpose.
