Description

Have air defense and beat the ail gun of function

(1) technical field

The utility model relates to a kind of ail gun, and especially a kind of have air defense and beat the ail gun of function.

(2) background technology

Existing ail gun has quick detach and antiaircraft function of beating, the structure that air defense is beaten is: above the nail folder ejector pin block is set, iron block is installed in end at the ejector pin block, described iron block cooperates with recess on the curved bar, when not having nail in the nail folder, iron block is got back to rifle mouth position under the pulling force effect of wind spring, and iron block is pushed down recess, curved bar can not upwards move freely, and can not start striker; When having nail to push the rifle mouth in the nail folder, the ejector pin block moves backward, and iron block moves backward, and iron block is away from the top of recess, and curved bar can freely move up, and after moving on the curved bar, works as cocking, and starting switch starts striker, by one piece of nail of rifle mouth emission.The shortcoming that exists is: when ejector pin block post-tensioning, if the rifle mouth is pressed on the workpiece, cocking can cause and mistakenly launch, and it is not high that security performance is beaten in air defense.

(3) summary of the invention

In order to overcome the deficiency that may causing of existing ail gun mistakenly launches, security performance is not high, the utility model provides a kind of can avoid causing that mistakenly launching, strengthen air defense beats the antiaircraft ail gun of function of beating of having of security performance.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of have air defense and beat the ail gun of function, comprise gun rack, the rifle mouth, the nail folder, be provided with striker in the described gun rack, the striker actuating mechanism, the rifle mouth is installed in described striker below, the side of described rifle mouth is equipped with the nail folder, the bottom of described rifle mouth is with sliding sleeve, described sliding sleeve is fixedlyed connected with adjusting nut, described adjusting nut is threaded with curved bar, the top free end of described curved bar and the interlock of described striker actuating mechanism, the lower end of described curved bar has hook, described hook is positioned at rifle mouth and a side of following closely the junction that presss from both sides, the opposite side that presss from both sides the junction at described rifle mouth and nail is provided with pressure nail piece, and described pressure nail piece has resetting-mechanism, and described pressure nail piece is on the described hook.

As preferred a kind of scheme: described resetting-mechanism is a torsion spring, and described pressure nail piece is provided with pin-and-hole, and described straight pin passes described pin-and-hole, and described torsion spring set is connected on the straight pin, and described straight pin is fixedlyed connected with the rifle mouth.

As preferred another kind of scheme: described straight pin is fixedlyed connected with the quick detach cover plate, and described quick detach cover plate one side is connected with the rifle mouth rotationally by pivot pin, and the opposite side of described quick detach cover plate is installed in the pin-and-hole of rifle mouth by the quick detach pin.

Further, described curved bar middle part has stopper slot, and sleeve passes the axis hole end face that described stopper slot is installed in the rifle mouth, installs by screw.

Further again, described striker actuating mechanism comprises starting switch, trigger, described starting switch is provided with plunger button, described trigger comprises trigger body, compressing tablet, resilient key, and described compressing tablet is positioned at the below of described plunger button, and described trigger body is connected rotationally with gun rack, described trigger body is provided with pin-and-hole, described resilient key inserts in the described pin-and-hole, and an end of described compressing tablet is installed between resilient key and the trigger body, and the other end of described compressing tablet cooperates with the top free end of curved bar.

Further, be provided with additional groove on described rifle mouth, described pressure nail piece and hook all are positioned at additional groove, and described pressure nail piece is positioned at the below of the last cell wall of additional groove, and described hook is positioned at the top of the following cell wall of additional groove.

Technical conceive of the present utility model is: limited sleeve of curved bar and sliding sleeve are spacing can only be done along rifle mouth axial-movement, when not having nail in the nail folder, press the nail piece to be subjected to the power effect of resetting-mechanism (torsion spring), make and press nail piece rotation set angle (being preferably 60 °), press this moment the nail piece to be in the upper end of curved bar hook, even if when ail gun rifle mouth is pressed on the workpiece, the hook of curved bar is owing to be subjected to pressing the nail piece to stop, and can't do rectilinear motion along rifle mouth axis, play the air defense effect of beating.

Air defense knotting structure of the present utility model with ejector pin block onrelevant, even if during ejector pin block post-tensioning, as long as do not have nail in the nail folder, if the rifle mouth is pressed on the workpiece, cocking can or not cause yet and mistakenly launches, and has strengthened air defense and has beaten security performance.

In order to prevent that straight pin from rupturing in the hook motion that is subjected to curved bar, so done stopper slot on the rifle mouth, stops and press the motion of nail piece.

Straight pin is fixedlyed connected with the quick detach cover plate, have the air defense beat function in, have the function that piece is torn open concurrently.The effect of quick detach pin when nailing, when nail is snapped in the rifle mouth, can draw the quick detach pin to deviate from pin-and-hole on the rifle mouth, and the quick detach cover plate is the pivot rotation with the pivot pin, takes out bad nail.

The beneficial effects of the utility model mainly show: can avoid 1, causing that mistakenly launching, strengthen air defense beats security performance; 2, have the quick detach function concurrently.
