The utility model is formed by that two cylindrical cams are additionally arranged between a trigger and a bolt in an existing double acting pistol, wherein, end points of the bolt are positioned in the cylindrical cams, and one end of each of the cylindrical cams is connected with a driving disc which is driven by the trigger. Therefore, in the course of using a pistol, the utility model offers safety for each bullet through the trigger, and the fastening force and the travel of the trigger are kept the same between a first round bullet and a follow-up bullet, and meanwhile, a dud can be loaded into or unloaded from a bore by a single hand through the trigger.

Description

Be used for the pistol safeties

The utility model relates to and is used for the pistol safeties, particularly two operated pistol safeties.

At present, known pistol insurance is usually by firing pin insurance and the control of hammer sear.Its working method is manual operation.And, no bullet in meeting thorax and need load the time, or when withdrawing from the bore duds, all need two palmistry interworkings to close, spur sleeve, just can finish above-mentioned action.

So above-mentioned working method has following problem:

At first, firing pin insurance has only when finger and is pressed on the trigger and could discharges, though this can reduce the danger of cocking off, works as the user, is subjected to bad or rugged environment influences and when being in biotonus, its sensation and control trigger pull and will be weakened.And in the pistol of now equipping, single action is pulled button button power too weak (about 1.4kg-1.5kg).This just often causes unconscious shooting, even by own entrained weapon self inflicted injury.This emerges in an endless stream.

Secondly, the hammer sear on two operated pistols is a kind of good insurance mode.But its operation sequence is anti-convention (by down down), and simultaneously, it is again manual, so easily it is forgotten.And in a single day forget, but be danger close.Because it is to be in to stop firing point (lower position).And two operated pistols of now equipping are have to open fire fast and prevail against one's opponent fire superiority.But because existing two operated pistols are wanted pulloff, firing lock is finished continuously wait to send out and pull the trigger two actions, this just causes first bullet and follow-up bullet to buckle different on power and the stroke at trigger.Causing therefrom that first bullet tends to beat flies.In order to eliminate the harmful effect when shooting of first bullet, some people just simply pulls hammer with hand in contact battle, What is more, before criminal aiming, in order to shoot second, third bullet, just towards the sky or a direction emission roughly bullet of running initially in the single action mode.Though this is very practical, exposed ejaculator's position.Causing immediately is criminal's fire assault, causes unnecessary injures and deaths.This is the purpose of the two operated pistols of design and contrary also and originally.

Once more, when meeting unexpected situation, need extract pistol shooting and do not have when bullet in the bore, need remove to spur sleeve, push away bullet and load with the another hand.Equally, in meeting thorax, during duds, also need the another hand to remove to spur sleeve, duds in the thorax is dished out.Like this, the one, to move manyly, the time is long, and particularly in point-blank encounter, who is first bullet of shooting earlier, and is conclusive often.The 2nd, also have singlehanded cocking frame to finish singlehanded filling or move back duds, but this was both impracticable, also unreliable.Because, when the user is in high concentration, forefinger be difficult in the utmost point do continuously in the short time two do not connect be used to the action.Simultaneously, this working method, violent inertia fall with the external force effect under, cock off easily, parts are also yielding.

So, consider that from the actual conditions at scene whose rifle energy rifle was accurately shot the advantage who just can obtain to survive before the other side.Because first bullet (also being unique usually) relates to the long-drawn-out major issue of closing of life.

The purpose of this utility model is to have the ability to every bullet provides reliable insurance for pistol provides a kind of, simultaneously, can simplify again and use and operation sequence, thereby make shooting become faster.First higher security insurance operating means of hit probability that plays.

The purpose of this utility model is achieved in that its two ends just enter in two cylindrical cams after gunlock pushes away bullet and loads, and like this, is just isolated by cylindrical cam between firing pin and the bullet and pins, and is in uncocked position.When percussion, only need, and drive drive plate by cocking, two cylindrical cams are rotated synchronously, make the inclined-plane on the cylindrical cam promote gunlock, and its straight line is retreated.After putting in place, under recuperator means promotes, when the end points on the gunlock is crossed check valve on the cylindrical cam, firing pin percussion bullet.Simultaneously, extractor is caught shell case, and under the kick effect, the shell case of dishing out, and promote two cylindrical cams and rotate simultaneously.After the gunlock back seat put in place, gunlock pushed a bullet and loads under recuperator means promotes.At this moment, just finished a shooting circulation.Pistol is in uncocked position again.Meeting one hand when withdrawing from the thorax duds, only need to continue cocking, and, force two cylindrical cams to continue rotation by drive plate, utilize the inclined-plane on the cylindrical cam to force the gunlock straight line to retreat, extractor is extracted duds out, in ejection very under the effect, outside the rifle of dishing out.Equally, when there not being when bullet in the bore, also only need cocking, utilize the inclined-plane in the cylindrical cam rotation, promote the gunlock straight line and retreat, after putting in place, push away bullet again and load, at this moment, loosen trigger, pistol is promptly located uncocked position.This has just reduced some preparation property fires of preshot.As use the hammer sear and pull sleeve etc.

Because the starting point of the present utility model is to provide passive insurance for every bullet by higher trigger button power, and make between first bullet and the follow-up bullet at trigger and buckle power and stroke is consistent, and realize singlehanded filling and move back the ability of duds by trigger, reach the simplification service routine, shorten the reaction time, improve the purpose that first-round hit requires, so, to existing bullet, inside and outside trajectory does not all have any change.It is simple in structure that two cylindrical cams have, and also do not have specific (special) requirements on material and manufacturing process, and it is also easy to make.

Like this, be that the pistol insurance is the most natural in the existing safeties by higher trigger button masterpiece, also be the easiest, and, realize that by trigger singlehanded filling and one hand withdraw from duds in the thorax, also be the most rational.

Below in conjunction with drawings and Examples utility model is described further.

In above-mentioned accompanying drawing, 1, gun barrel, 2, gunlock, 3, bullet, 4, extractor, 5, firing pin, 6, slide block, 7, slide block spring, 8, two cylindrical cams of A, B, 9, trigger, 10, drive plate, 11, recuperator means gear and kicker, 12, magazine, 13, fixedly ejection very, 14, be in magazine (2) on bullet.

In figure (1), be respectively that two cylindrical cams 8 of A, B are in the expanded view along its girth.In this figure, gunlock 2 two-end-point C stop in two cylindrical cams 8 of A, B in the CD inclined-plane of percussion respectively.Two check valve I are drawing under the valve spring J effect, and an end abuts against on the DE face that leads to percussion, and keep on the straight line with the EF inclined-plane that is used for cushioning back seat and drives cylindrical cam 8 rotation.Draw valve spring J one end to be fixed in the cylindrical cam 8, an end is fixed on the check valve I.Like this, when gunlock 2 two ends C put in place because of two cylindrical cams of A, B 8 rotation is subjected to the CD inclined-plane to promote linearly to retreat, gunlock 2 two-end-point C were with the DE face and cross check valve I and pull the trigger bullet forward.When back seat, check valve I directly blocks gunlock 2 two-end-point C and retreats along the DE straight line, and forces it to retreat along EF inclined-plane straight line, also promotes 2 cylinder cams 8 of A, B to rotate a circle, for next shooting circulation is got ready.In addition, the GH inclined-plane on two cylindrical cams 8 of A, B is to retreat as promotion gunlock 2 straight lines to realize singlehanded filling and move back duds.FC is gunlock 2 multiple stand in channels.

In figure (2), dress bullet 3 is arranged in gun barrel 1 rear bore, back 4 millimeters is that to be fixed on the gunlock 2 be firing pin 5 and extractor 4 at distance bullet 3, what slide block 6 and slide block spring 7 were closed is fixed on the gunlock 2, promptly in firing pin 5 and extractor 4 back, its axis and rifle spring 1 axis are upwards 4 ° angle, and ejection very 13 is positioned at firing pin 5 and extractor 4 back and is fixed on left side on the gun platform.In the recuperator means 11 two advance gear again and are positioned on the gun platform both sides, rear and are connected with gunlock 2 both sides, i.e. gunlock 2 walkings are being advanced on the gear again, and entering the gear centre again at two is kicker.Below gun barrel 1 and gunlock 2 two cylindrical cams 8 of A, B of placing side by side, its end is fixed in the rifle body, and its other end links to each other with drive plate 10, is connected and drive plate 10 is axial 90 ° with the trigger 9 of front, in trigger 9 freewheel clutch is housed, magazine 12 is arranged in the small of the stock.

In figure (3), gunlock 2 two-end-point C are in two cylindrical cams 8 of A placed side by side, B.Follow-up bullet is the upper end in magazine 12.Ejection very position 13 is fixed on the gun platform left side.Two are advanced gear again in both sides, gun platform rear in the recuperator means 11, and advancing gear again middle at two is two kickers, and the one end is separately fixed at two and advances again on the gear, and the other end is fixed on the gun platform, provides power for advancing gear driven gunlock 2 again.

In figure (4), gun barrel is for 1 time two cylindrical cams 8 of A, B of placing side by side.Two cylindrical cam 8 one ends of A, B are positioned on drive plate 10 girths.Trigger 9 and drive plate 10 diaxons intersect and are 90 ° and be connected.

The operation sequence of the utility model embodiment is as follows: after first bullet 3 is received in thorax, when to be hit, gunlock 2 two-end-point C enter in the CD inclined-plane that two cylindrical cams of A, B 8 stop percussion, and are fixed and block, make firing pin 54 millimeters, promptly be in uncocked position apart from 3 ends of bullet.This has just been avoided the accidents such as the accidental injury of cocking off that cause because of external force effects such as violent inertia fall.Simultaneously, the percussion energy of firing pin 5 also is lower than the required percussion energy of bullet 3.

When percussion, pull and pull 9, and drive drive plate 10 and two cylindrical cams 8 of A, B rotate synchronously, force that straight line retreats 6 millimeters being in that the gunlock 2 two-end-point C that stop firing position are subjected to promote along the CD inclined-plane, be to advance on the gear to walk 6 millimeters again in the both sides of gunlock 2 in recuperator means 11, and turn round and press two kickers to carry out energy storage, thereby make firing pin 5 reach the required energy of percussion bullet 3.After putting in place, under recuperator means 11 effect, gunlock 2 two-end-point C are again along the DE face in two cylindrical cams 8 of A, B, and cross check valve I, preshoot percussion bullet 3, and meanwhile, dog extractor 4 is embraced bullet 3 root edges, promptly is in the percussion state.At this moment, gunlock 2 is free gunlock working method.Slide block 6 and overcomes the resistance of slide block spring 7 after absorbing the energy that recuperator means 11 discharged, impact before upwards being 4 ° angle with gun barrel 1 axis, suppresses gun barrel 1 and upwards beats.

At this moment, trigger 9 button power are 5.5kg, and stroke is 6 millimeters.

Behind the slide block 6 and recuperator means 11 active forces of kick that after bullet 3 is by percussion, is produced greater than preshoot, gunlock 2 beginning back seats.Check valve I on two cylindrical cams 8 of A, B has stoped retreating along DE inclined-plane straight line of gunlock 2 two-end-point C under the effect of extension spring J, and forces it to cushion back seat and unblank because of the resistance that is subjected to the EF inclined-plane.At this moment, gunlock 2 is semi-free gunlock working method.Along with the straight line of gunlock 2 two-end-point C retreats, also just promote the rotation of A, two cylindrical cams 8 of B, extractor 4 has been extracted shell case out, and in ejection very under 13 the effect, and the shell case rifle of dishing out is external.

When gunlock 2 drives because of kick to advance gear in the recuperator means 11 again and be and be rotated counterclockwise and after 38 millimeters of last walkings, promptly the back simultaneously, also is that gunlock 2 two-end-point C retreat into terminal point at two cylindrical cams 8 of A, B along EF inclined-plane straight line to the seat.At this moment, gunlock 2 two in recuperator means 11 advance gear again under kicker effect separately, turn clockwise, and promote gunlock 2 its two-end-point C and advance again along FC inclined-plane in two cylindrical cams 8 of A, B.And the follow-up bullet 14 that promotes magazine 12 upper ends loads, and gunlock 2 two-end-points arrive along FC when being in the C point that stops percussion in two cylindrical cams 8 of A, B, and gunlock 2 is prevented from advancing again, and fixedly blocks.Be in uncocked position.At this moment, two cylindrical cams 8 of A, B just in time revolve and turn around, and, because of in trigger 9, freewheel clutch is housed, so the rotation of A, two cylindrical cams 8 of B can not influence resetting of trigger 9.Like this, provide passive insurance for every bullet, and used button power and the stroke of each percussion of trigger 9 is consistent all by trigger 9.

After percussion, find that the bullet 3 load is duds, at this moment, need to continue cocking 9, make the gunlock 2 two-end-point C that are arranged in A, two cylindrical cams 8 of B promoted by the GH inclined-plane and straight line retreats.Extractor 4 is extracted duds 3 out, and endures under 13 effects in ejection, and it is dished out.When gunlock 2 two-end-point C fall back in two cylindrical cams 8 of A, B the H point, promptly put in place.Under recuperator means 11 promotes, push away the follow-up bullet 14 in magazine 12 upper ends and load immediately, come back to non-hitting state.

At this moment, trigger button power is 6.5Kg, 12 millimeters of strokes.

After loosening trigger 9, trigger 9 resets, and triggering pulling 9 again, promptly directly changes the percussion state over to from non-hitting state again.

The process that one hand loads is identical with the above-mentioned duds process of moving back, and has just lacked a process of taking out, throwing duds.

Like this, embodiment of the present utility model just has the ability that one hand loads, and has reduced operation sequence and moved back duds and the secondary percussion time.
