Abstract

A safety device of a shooting system is provided with a safety lever which is inserted in the inner part of a crossbow body from the tail part of a crossbow. The front end of the safety lever is provided with a half lever body retaining extension block which can block the route that a trigger ejects the crossbow cord before the safety lever pushes forwards to make the cord not fire. When the safety lever pulls backwards, the route that the crossbow springs is in an open state, and the firing can be carried out. By utilizing the structure, the safety function for the firing action of the crossbow can be obtained.

Description

Safety device of crossbow shooting system

The utility model relates to a kind of safeties of crossbow trigger system.

Because crossbow is extremely strong motion of a kind of percussion power and hunting apparatus, must very carefully just can avoid unexpected injury during use, in evolution in the past, crossbow is mostly only paid attention to the change on the external form, with attraction consumer's selection, and the safety measure of gunlock itself is seldom considered, therefore, in use, often have because of touching the phenomenon that trigger produces unexpected ejection (cocking off), as easy as rolling off a log generation danger carelessly.

For preventing above-mentioned phenomenon, the purpose of this utility model is to provide a kind of safeties to the crossbow trigger system, as the device that prevent unexpected percussion of crossbow before shooting, to improve the security of whole tool crossbow.

The purpose of this utility model is achieved by following technical scheme, the safeties of this crossbow trigger system are provided with a kind of safeties of crossbow trigger system, it is characterized in that being provided with a bumper bar and insert crossbow body inside from crossbow body afterbody, and reserve its tail end outside crossbow body afterbody, end is provided with half shaft extension block before this bumper bar, on this extension block, be provided with the longitudinally extending slippage slot that radially connects of shaft on one day, and two pits that hold steel ball are set before and after the one segment distance place in the slippage slot rear end, be communicated with by a shallow slot between two pits;

One lock(ing) bolt is screwed into from top to down from trigger mechanism of a crossbow back of the body place sliding decide the screw on the piece and be locked in and slidingly decide on the piece, and the overhanging tail end of lock(ing) bolt stretches in the slippage slot of above-mentioned bumper bar, use limit bumper bar before after moving range and prevent the bumper bar turn;

Trigger mechanism of a crossbow back is provided with a through hole with respect to the rear of lock(ing) bolt position, be placed with a steel ball of being pushed down by spring in this through hole, embed in the pit of above-mentioned front and back on the terminal location that this steel ball is passed before and after bumper bar, reach the effect of location fastening bumper bar;

Press said structure, when pushing away before the bumper bar, the extension block of its front end of mat is sealed the approach that the crossbow string ejects the groove of tuning up, and when bumper bar backward during drawing, promptly open this launches approach.Thereby realize the effect of trigger system switch insurance.

Now reach preferred embodiment in conjunction with the accompanying drawings entity structure of the present utility model is carried out more deep explanation.In the accompanying drawings,

Fig. 1 is perspective appearance figure of the present utility model,

Fig. 2 illustrates gunlock part of the present utility model with the perspective exploded view form,

Fig. 3 is the cutaway views of percussion safeties of the present utility model when shutting,

Fig. 4 is the cutaway views of percussion safeties of the present utility model when opening and pull the trigger.

Now referring to each figure, the utility model mainly inserts a bumper bar 2 at the afterbody of crossbow body 1, end is established half shaft extension block 21 before the bumper bar 2, on this extension block 21, be provided with the longitudinally extending slippage slot 22 that radially connects of shaft on one day, and a segment distance place is provided with 23,24 of two pit 23,24, two pits that hold steel ball and is communicated with by a shallow slot 25 in its back-end;

One lock(ing) bolt 3 locks by the sliding screw of deciding on the piece 4 from the trigger mechanism of a crossbow back of the body 11, and penetrate with its tail end 31 in the slippage slot 22 of above-mentioned bumper bar 2, passing scope in back is limited by lock(ing) bolt 3 and slippage slot 22 before making bumper bar 2, and bumper bar 2 is not also produced spinning movement therefrom;

On the trigger mechanism of a crossbow back of the body 11, be provided with a through hole 12, be placed with a steel ball 13 that is suppressed by spring in this through hole 12, this steel ball 13 embeds on the terminal location that pass bumper bar 2 front and back and holds in the pit 23,24 of steel ball, uses the effect that reaches location fastening bumper bar 2.

Press the utility model of said structure, when crossbow will be prepared to launch crossbow bolt, at first make it to embed in the groove 14 of tuning up, again crossbow bolt is positioned over 15 places, body of a gun top, enter arm-to-arm with the hook 5 drawing crossbow strings 6 of tuning up; This moment is as pushing away bumper bar 2 forward, steel ball 13 embeddings are fixed in the pit 24 of back, then the extension block 21 of bumper bar front end covers the groove 14 of tuning up, block the ejection approach of crossbow string 6, therefore, even trigger trigger 7, also can't pull the trigger because of being hampered by above-mentioned extension block 21, that is crossbow is in the state shut of insurance, as shown in Figure 3; As with bumper bar 2 drawing backward, steel ball 13 embeddings are fixed on before in the pit 23, above-mentioned extension block 21 promptly retreats and the groove 14 of will not tuning up covers, at this moment, trigger trigger 7 and can push crossbow string 6, crossbow string 6 can be deviate from from the groove 14 of tuning up and realize pulling the trigger, crossbow bolt is penetrated, as shown in Figure 4.

In sum, should confirm that the safeties of the trigger system of the utility model can reach the percussion safety effect of expection, provide a kind of reasonable defensive measure for preventing that crossbow from producing to cock off, really creative and practicality.

Claims

1, a kind of safeties of crossbow trigger system is characterized in that being provided with

One bumper bar inserts crossbow body inside from crossbow body afterbody, and reserve its tail end outside crossbow body afterbody, end is provided with half shaft extension block before this bumper bar, on this extension block, be provided with the longitudinally extending slippage slot that radially connects of shaft on one day, and two pits that hold steel ball are set before and after the one segment distance place in the slippage slot rear end, be communicated with by a shallow slot between two pits;

Press said structure, when pushing away before the bumper bar, the extension block of its front end of mat is sealed the approach that the crossbow string ejects the groove of tuning up, and when bumper bar backward during drawing, promptly open this launches approach, thereby realizes the effect of trigger system switch insurance.
