Abstract

The utility model relates to an automatic safety structure for a novel trigger of a shotgun. The automatic safety structure comprises a safety body and a safety button, wherein a slotted hole is formed in the safety button; a blocking shaft is mounted at the upper end of the slotted hole, a spring is arranged in the middle and a screw is encapsulated at the lower end; the blocking shaft penetrates the safety button and is blocked on the outer side of a U-shaped groove in the upper end of a safety push rod; the middle of the safety push rod is in movable connection with a fixed shaft; the lower part of the safety push rod is in movable connection with the safety body through a rotating shaft; a safety arm is arranged at the front end of the safety body, and another safety arm is arranged at the rear end; a matching surface in leaning connection with a rear trigger is arranged on the safety arm; another matching surface in leaning connection with a front trigger is arranged on the another safety arm; the safety body is provided with a sliding aperture passage connected with a fixed mandrel in a sliding and matching manner; and the upper surface of the safety body is in leaning connection with a cartridge receiver matching surface. The automatic safety structure is simple, has a reasonable design, lowers the manufacturing difficulty and cost, is simple and convenient to mount, can be simply and quickly operated, ensures reliable safety action of the trigger and has high safety factors.

Description

The novel trigger voluntary insurance of shotgun structure

Technical field

The utility model relates to a kind of Trigger safety mechanism, particularly relates to a kind of for the novel shotgun trigger voluntary insurance mechanism on the double-barrelled shotgun

Background technology

At present, limit insurance and non-insured position with plate-shaped springs on the known shotgun Trigger safety device.The insurance of this insurance institution is also unreliable, causes the mistake percussion easily, the safety that threatens the user, and inconvenient operation influences result of use simultaneously.Therefore, be necessary to research and develop novel percussion and insurance institution, solve the problem that insurance is unreliable and operation is not simple and direct effectively.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and insurance is reliable, the novel trigger voluntary insurance of shotgun simple to operation structure.

In order to achieve the above object, the technical solution adopted in the utility model is: comprise fuse, safety button, described safety button inside is provided with slotted eye, the slotted eye upper end is equipped with block axis, the middle part is provided with spring, the lower end is packaged with screw, described block axis runs through safety button, end in the U-lag outside of insurance push rod upper end, insurance push rod middle part flexibly connects with fixed axis, and insurance push rod bottom flexibly connects by rotating shaft and fuse, and the front end of described fuse is provided with the insurance arm, the rear end is provided with the insurance arm, the insurance arm is provided with the mating surface that is abutted against with rear trigger, and the insurance arm is provided with the mating surface that is abutted against with fore trigger, and fuse is provided with the slip duct, slip duct and fixed central spindle slide and connect, and the fuse upper surface also is abutted against mutually with the casing mating surface.

The utility model has the advantages that:

1. simple in structure, reasonable in design, reduce manufacture difficulty and cost;

2. install simple, convenient, simple to operation;

3. Trigger safety reliable in action, the safety coefficient height.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 4 as can be known, the utility model comprises fuse 3, safety button 12, described safety button 12 inside are provided with slotted eye, the slotted eye upper end is equipped with block axis 11, the middle part is provided with spring 10, the lower end is packaged with screw 9, described block axis 11 runs through safety button 12, end in U-lag 25 outsides of insurance push rod 8 upper ends, insurance push rod 8 middle parts and fixed axis 7 flexibly connect, and insurance push rod 8 bottoms flexibly connect by rotating shaft 6 and fuse 3, and the front end of described fuse 3 is provided with insurance arm 4, the rear end is provided with insurance arm 16, insurance arm 4 is provided with the mating surface 21 that is abutted against with rear trigger 2, and insurance arm 16 is provided with the mating surface 20 that is abutted against with fore trigger 1, and fuse 3 is provided with slip duct 24, slide with fixed central spindle 22 and connect in slip duct 24, fuse 3 upper surfaces also are abutted against mutually with casing mating surface 23.

The utility model voluntary insurance mechanism, when percussion, block axis 11 contacts with mating surface 17 places of casing 5, when being furious, a pole socket axle 13 of being furious moves backward, make insurance push rod 8 rotate counterclockwise around fixed axis 7 by the contact site 19 on the insurance push rod 8, its top is in rotary course, U-lag 24 on the insurance push rod 8 can be stirred the block axis 11 that is installed in the safety button 12 backward and slide backward along the mating surface with casing, when sliding into mating surface 18 places, spring 10 can head into block axis 11 in the fit circular arc of mating surface 18, forms gripping orientation this moment.Insurance push rod 8 bottoms are connected with fuse 3 by rotating shaft 6, because fuse 3 upper surfaces are subjected to the restriction of casing mating surface 23, rotation along with insurance push rod 8, by Fig. 3, Fig. 4 knows, fuse 3 can only travel forward along casing mating surface 23, again because the restriction of fixed central spindle 22, when fuse 3 moves to the extreme right position of slip duct 24 restrictions, the insurance arm 4 of projection on the fuse 3, insurance arm 16 moves to rear trigger 2 respectively, the top of fore trigger 1, mating surface 20, mating surface 21 respectively with fore trigger 1, the contact of rear trigger 2 upper surfaces, at this moment, the action of being furious is also finished simultaneously, two triggers 1, trigger is all limited 2 this moments, even cocking 1,2 also can't make trigger around separately rotating shaft 14, rotating shaft 15 is realized rotation, promote safety button 12 forward to the situation of non-insured position in no any external force, gun will keep the safety position of trigger always reliably.
