Description

A kind of multiplex bow and crossbow percussion lock

Technical fieldThe utility model belongs to the crossbow technical field, is specifically related to a kind of multiplex bow and crossbow percussion lock.

Background technologyThe crossbow of prior art, function singleness can only be shot an arrow, and can not pull the trigger steel ball, and poor accuracy, also has hidden danger.

Summary of the inventionThe purpose of this utility model is to solve the technical problem that prior art exists function singleness and poor stability.A kind of multiplex bow and crossbow percussion lock is provided.

To achieve these goals, the multiplex bow and crossbow percussion lock of the utility model, its main points are that it comprises lower bullet button, insurance, latch hook, lever contiguous block and trigger, described lower bullet button is communicated with the crossbow hall of in-built steel ball; One end of described insurance and the bottom of lower bullet button join, and the upper end of the other end and latch hook joins; Be provided with the centering type sear below described insurance, an end of centering type sear and the lower end of latch hook join, and the other end of centering type sear and lever contiguous block join; Described trigger be placed in the lever contiguous block below.

The utility model critical piece is forged by the high-quality steel and forms, but insurance all on-hooks in any position; The lever kind of drive significantly reduces trigger pull, the centering type sear is combined with latch hook and is made parts reach self-locking state, the off line phenomenon will not appear, the utility model can be shot an arrow and can be shot steel ball, one crossbow is multiplex, has solved the technical problem that prior art exists function singleness and poor stability.

Description of drawingsFig. 1 is that the utility model is in and closes the hook state structural representation;

Fig. 2 is that the utility model is in unlatching percussion status architecture schematic diagram.

In figure 1, latch hook 2, centering type sear 3, lever contiguous block 4, trigger 5, insurance 6, lower bullet button 7, steel ball

The specific embodimentSee figures.1.and.2, it comprises lower bullet button 6, insurance 5, latch hook 1, lever contiguous block 3 and trigger 4 the utility model, and described lower bullet button 6 is communicated with the crossbow hall of in-built steel ball 7; One end of described insurance 5 and the bottom of lower bullet button 6 join, and the upper end of the other end and latch hook 1 joins; Be provided with centering type sear 2 below described insurance 5, an end of centering type sear 2 and the lower end of latch hook 1 join, and the other end of centering type sear 2 and lever contiguous block 3 join; Described trigger 4 be placed in lever contiguous block 3 below.Under opening, under the effect of external force bowstring, latch hook 1 turn to closed condition; simultaneously, centering type sear 2 moves to the closed condition of closed condition position assurance latch hook 1, simultaneously; insurance 5 plays a protective role, and so far completes opening to the conversion (with reference to Fig. 1) of closed condition.In off position, after insurance 5 is switched to opening, trigger 4 is after flip an angle under the effect of external force (with reference to Fig. 2), centering type sear 2 is under the drive of lever contiguous block 3, disengaging closed condition position, latch hook 1 turn to opening under the effect of external force, realize opening.
