Abstract
The utility model relates to a firearm secondary bolt opening safety mechanism which comprises a safety lever arranged on the outer side of a free end of a firing resisting iron pole of a firing device, a rotating pin and a return torsion spring are arranged in the middle of the safety lever, the middle of the safety lever protrudes upwards smoothly, a guide rope seat of a firearm is positioned on a cradle and slides above the safety lever, the safety lever rotates around the rotating pin and returns through the return torsion spring, the highest point of the middle of the safety lever is higher than the lowest point of the rope guide seat, the tail end of the safety lever tilts upwards to be exactly positioned right ahead the free end of the firing resisting iron pole and fitted with the firing resisting iron pole, and the tail end fails down after the safety lever returns. The firearm secondary bolt opening safety mechanism is safe and reliable to use, reasonable in integral structural arrangement, attractive in appearance, few in parts, good in manufacturability and convenient to maintain.
Description
Technical field
The utility model relates to the conventional weapons technology field, specifically, relates to a kind of firearms secondary and opens bolt insurance institution, and when firearms can not normally be pulled the trigger, the operator detained not trigger action, thereby it is not in place to remind operator's firearms to open bolt, should pull up a horse and open bolt one time again.
Background technology
Along with the development of new military change and military technology, when war situation and combat mission require armament systems can satisfy the required fast reaction of modernized war, maneuver of fire power, self-protection, the lethality of armament systems has been brought up to new level.Thus, it is trend of the times that the large caliber weapon system gets on the bus, 14.5 millimeters vehicle-mounted arising at the historic moment of firearms that thereupon grow up, but the impact that brings greatly owing to 14.5 millimeters firearms powers is out that bolt power is large, reach 65KG, first filling of firearms becomes a quite challenging problem.In the vehicular weapons system, some employing movable pulley forms when reducing out bolt power, have increased by one times but open the bolt stroke, and are originally inadvisable with regard to limited built-in rifle tower for the space; Some employing secondary unbolting mechanisms, for example QTA, QTB product, the bolt stroke is constant can to reduce to 18.6KG from 65KG with opening bolt power in the situation that guarantee to open, but also has a problem, and secondary is opened bolt must open the bolt secondary simultaneously, if only open bolt once, firearms have firing action but can not realize percussion, if open continuously bolt three times, firearms can be freed sear but can not be realized percussion, be easy in this case bungle the chance of winning a battle, repeated multiple times such operation also can the artificial damage part.For this reason, need to have a kind of insurance institution to remind the operator, when firearms can not normally be pulled the trigger, the operator detained not trigger action, thereby it is not in place to remind operator's firearms to open bolt, should pull up a horse and open bolt one time again.When in case of emergency gaining time, also protected and opened bolt mechanism not by artificial damage.
The utility model content
The purpose of this utility model is to adapt to the reality needs, provides a kind of firearms secondary to open bolt insurance institution.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
The firearms secondary leaves bolt insurance institution, the bumper rail that comprises the sear bar free end outside that is arranged at firing device, the middle part of described bumper rail is provided with rotational pin, described bumper rail middle part smoothly raises up, also be provided with the return torsion spring, the conductor rope seat of firearms is positioned on the reel cage and above bumper rail and slides, described bumper rail rotates that untie-sell is rotated and by return torsion spring return, described bumper rail middle part peak is higher than the minimum point of conductor rope seat, the bumper rail tail end is upturned and just is positioned at described sear bar free end dead ahead and fits with the sear bar afterwards, and bumper rail return rearward end falls.
Be provided with the longitudinal spacing groove between the front end outward flange of described bumper rail and the rotational pin, be provided with the spacer pin that is positioned on the reel cage in the described stopper slot, the front end of described return torsion spring is located after hooking the lower surface of the upper surface of walking around successively spacer pin behind the front edge of bumper rail and rotational pin.
The beneficial effects of the utility model are:
1. when firearms can not normally be pulled the trigger, the operator detained not trigger action, thereby it is not in place to remind operator's firearms to open bolt, should pull up a horse and open bolt one time again, when in case of emergency gaining time, had also protected and had opened bolt mechanism not by artificial damage;
2. simple to operate when decomposing fully, easy to maintenance, safe and reliable;
3. few, the good manufacturability of connection and reasonable arrangement on the overall structure, good looking appearance, part number of packages.
Description of drawings
Fig. 1 is structure principle chart of the present utility model;
Fig. 2 is the structure principle chart when the conductor rope seat is positioned at directly over the bumper rail middle part among Fig. 1;
Fig. 3 is the structure principle chart that the conductor rope seat is positioned at the another location among Fig. 2.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1---Fig. 3.
The firearms secondary leaves bolt insurance institution, the bumper rail 2 that comprises the sear bar 1 free end outside that is arranged at firing device, the middle part of described bumper rail 2 is provided with rotational pin 3, described bumper rail 2 middle parts smoothly raise up, also be provided with return torsion spring 4, the conductor rope seat 5 of firearms is positioned on the reel cage 8 and slides above bumper rail 2, described bumper rail 2 rotates that untie-sell 3 is rotated and by return torsion spring 4 returns, described bumper rail 2 middle part peaks are higher than the minimum point of conductor rope seat 5, bumper rail 2 tail ends are upturned and just are positioned at described sear bar 1 free end dead ahead and fit with sear bar 2 afterwards, and bumper rail 2 return rearward ends fall.
Be provided with longitudinal spacing groove 6 between the front end outward flange of described bumper rail 2 and the rotational pin 3, be provided with the spacer pin 7 that is positioned on the reel cage 8 in the described stopper slot 6, the front end of described return torsion spring 4 is located after hooking the lower surface of the upper surface of walking around successively spacer pin 7 behind the front edge of bumper rail 2 and rotational pin 3.
Use principle of the present utility model is summarized as follows:
The setting of stopper slot 6 and spacer pin 7 has not only made things convenient for the installation of return torsion spring, and also convenient height to the perk of bumper rail two ends carries out accurately spacing.
Simple to operate when the utility model decomposes fully, easy to maintenance, safe and reliable.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
