Description

Pneumatic gun post

The field that the present invention relates to

The present invention relates to the pneumatic self-defence projectile weapon of portable operation usefulness, particularly belong to shooting type cutter.

The state of the art

The known Britain during World War II and the U.S. are the pneumatic shooting fountain pen of secret service development, the airbrush (Air-Pen) of professional control of strategy (OSS) and special operations control (SOE).This gun post that is used for throwing malicious pin has standard spring-piston aerodynamic arrangement, and wherein the projection of instrument is to lean on the ability of air when the powered compressor of band spring piston to carry out.This kind device is not to be used for power to kill and wound purpose, soaks malicious instrument but be used for low noise ground to the target projection.

Existing known shooting cutter adopts the energy of Compressed Gas, for example Yi Sikeleiliewa (И. С к р ы л e в а) at magazine " firelock technician (М а с т e р Р у ж ь e) ", the pneumatic shooting cutter of describing in 27/28,1998 year.

In this tool structures, the piston that is arranged in the handle chamber has little plunger shaft, wherein is pressed into the compressed air in the cutter with air compressor or by means of compressed gas cylinder through reverse charge valve.Piston interacts with the instrument that is throwed, and the latter itself is short arrow.The arrow that is arranged on the handle end is fixed on the handle of cutter by means of the lever system that has the support of fighting.After this, air compressor is pressed into air in the plunger shaft.

Thumb started by press button during shooting, the latter is a part of dwindling the lever system of tripping force, and fight mechanism (в з в о д) lifts a blockade, and discharges arrow, and the gas in the plunger shaft expands, and invests target to arrow.The cutter of said structure can be used for land, also can be used under water.

The shortcoming of the cutter of similar structures is that the Compressed Gas the blowing pressure of preshot filling plunger shaft is little.

The big as far as possible pressure of Compressed Gas limits with the lever system gearratio of fight support.Improve the pressure of Compressed Gas in order to improve " muzzle energy ", tripping force is sharply increased,, and correspondingly shoot so that the power of thumb has been not enough to remove fight mechanism.Be about 20mm by above-mentioned figure medium scale (magazine " firelock technician " (М а с т e р Р у ж ь e) 27/28,1998 year) piston diameter, under 250 atmospheric pressure the blowing pressures, be about 785 kilograms through the power of piston action in the activation lever system.Even the power less with thumb physically also can not overcome similar power through lever system.

The shortcoming of this cutter is, and is unnatural equally towards the posture of this cutter of user for producing the shooting blade.Even under Pneumatic method; Recoil during shooting depends on that significantly the quality (even under little speed) of arrow possibly reach such numerical value; So that when cutter is launched (for example, under water, because " lubrication of water ") maybe be with holding incessantly; Cutter is with certain speed emission the time, and given in advance recoil possibly make insert tip injure user oneself.In addition; Factitious like this cutter posture is when shooting; The time lengthening that cutter changes to " pneumatic emission weapons " from " cold steel ", this not only possibly cause cutter to come off perhaps even lose cutter (for example, under water); When also maybe be in the time (from a kind of state to another kind of state-transition) not enough, it is impossible that the emission of success is become.The shortcoming of the cutter of this structure also is, can not carry out the emission second time, for example, does not hit when perhaps grappling with a group adversary.

So the basic shortcoming of the cutter of this structure is, the projection energy that kills and wounds arrow is little, can not carry out emission for the second time, use the danger of the factitious attitude of emission and inconvenient to the transformation of " pneumatic projection weapons " attitude from " cold steel ".

At this moment, see, guarantee and the similarly similar pneumatic gun post of the firearm gun post appearance as yet of bullet muzzle energy appearance and size from the state of the art.

Disclosure of an invention

Target of the present invention is the shortcoming that overcomes the most close analog, creates a kind of portable pneumatic gun post, is used for; For example, can not use the place that explosion danger is arranged of firearm projectile weapon to be used to the purpose of defending oneself, perhaps use under water; Use the shooting cutter like frogman, swimming fighter; Be used to kill and wound purpose, for example, kill and wound dangerous ocean fish and animal.

The specific embodiment

Pneumatic gun post (Fig. 1) contains body 1, and this body 1 is to keep handle, on this maintenance handle, is processed with airtight inflatable chamber 2.Block the end in chamber 2 with plug 3, be equipped with sealing ring 4 on the plug 3.On plug 3, be processed with cannelure, flexible valve collar 5 is installed on this cannelure, this valve collar 5 is blocked the interconnection that filling channel 6 is connected.

On plug 3, be processed with the protuberance 7 that has cannelure, configuration hermetic seal packing ring 8 on this protuberance 7.By the element of impelling (promptly below instrument) by shell 9 be attached to head 10 sharp-pointed on this shell 9 and form; This impelling element passes through the gasket arrangements of shell 9 on protuberance 7; By the element of impelling is the instrument of flechette-type; At this moment had the blade cutter shape or the dagger shape by the impelling element, this blade is fixedly mounted in and keeps last or might take off fast.And the flechette-type instrument can have the response part of spiral at head, and this helix is processed on the exit portion of guide groove of inflatable chamber 2, and the role of the gun barrel with helix is played the part of in this chamber 2.

Can be the blade that has afterbody of the dagger shape of the cutter shape that adds equally by the element of impelling; This afterbody is configured in the inflatable chamber 2; In this case; The blade that is installed on the handle has one or more guide grooves longitudinally; Above-mentioned guide groove supplies the one or more additional blades cutter shape or the dagger shape to use, and said guide groove can stop and adds blade and move up except the impelling direction either party, and is had the response part of the guide groove that is used for forever being installed in the blade on the handle by the blade cutter shape or the dagger shape that adds of impelling element.The additional cutter shape of this impelling element or the blade of dagger shape itself also can be one or more sharp-pointed edges of a knife.

Be configured in the chamber that the incompressible light material that can be had oneself by the part of impelling element in the inflatable chamber is filled.Above-mentioned incompressible material is made for relatively the shape of bar-empennage by the inner chamber of impelling element or by the chamber at impelling element rear portion.In housing 9, the bar-empennage 11 of can not be compressed and diameter 12 being increased is installed under the high the blowing pressure with the mode that can in housing, move.The internal diameter 13 that realization is dwindled in housing 9.And in bar-empennage, be formed on the sliding channel 14 that end has chamber 15.Processing is disposed the annular ring of Airtight gasket 16 and is entered the passage 17 in the opening 18 of the sharp-pointed portion 10 of head with big flow resistance in the sharp-pointed part 10 of head.

At this moment, device perhaps can be processed the chamber 2 that has one or more airtight inflations that separate, and said chamber 2 is positioned in the handle.So that can with the mutual co-operating of cocking mechanism act on by the impelling element or by the afterbody of impelling element, make simultaneously by the fluid pressure of impelling element or its afterbody from by impelling element or its afterbody to reached balance or overbalance by emitting side.

Be configured in the inflatable chamber 2 by the end of impelling element or by the afterbody of impelling element or be configured in the inflatable chamber 2 by the inner chamber of impelling element or can be by the passage and the atmosphere of the resistance that has big fluid pressure by the chamber of the afterbody of impelling element, this fluid resistance gets into the atmosphere from the end of airtight inflatable chamber 2 or by the front portion of impelling element.

Cocking mechanism 19 (Fig. 1) is configured in the main body 1 (Fig. 1) in Fig. 2, and this main body 1 has the handle 20 of axle 21, these 21 groove 18 mutual collaborative works with the sharp-pointed part 10 (Fig. 1) of head.The protector 23 of spring-like moves for 20 li at handle, and this head 24 is pulled out by spanner when removing hold mode.

Here; Disposing the shot block device 33 that moves relative to inflatable chamber by the afterbody of impelling element or on by the inner end of the afterbody of impelling element and inflatable chamber 2, this shot block device is the part of being thrown element or being thrown the fluid pressure balance system of element afterbody.

In addition, in an embodiment of this device, shot block device 33 can add inbuilt laser sight or target-sighting apparatus (not shown)

The work of device of the present invention is described below.

In Fig. 1 and Fig. 2, device is in inactive state.Device is full of the compression gases such as air that for example have pressure 350 and Geng Gao atmospheric pressure (maximum pressure in non-special Compressor Technology) through aeration tank.

Under ready condition; The elasticity valve collar 5 of the interconnection that cuts off the plug 3 that is communicated with the passage of proofreading and correct 6 is opened; Compression chamber 2 is compressed gas filling then, and when the bleed pressure balance of pressure in chamber 2 and base measuring pressure, ring 5 just cuts off the interconnection that is communicated with the passage of calibrating 6.The diameter of protuberance 7 is littler than the diameter of the shell 9 of instrument.Therefore the power in instrument impelling direction of fluid pressure generation begins to act on the shell 9, and described power equals above-mentioned shell 9 and the difference in areas of protuberance 7 and amassing that the pressure that is calibrated multiplies each other.Select this pressure, so that under the condition of the extreme value of this pressure, do not hinder with the power of finger through the sharp-pointed part 10 of head the power on the cocking mechanism 19 of being added to and just can easily open the cocking mechanism lock bolt.Act on the instrument with point to not for a short time at the Z-TEK of impelling one side direction, that is to say to make instrument reach fluid pressure balance.

Cocking mechanism 19 is knobs of a rotation; This handle the axle with by the impelling element or by the afterbody co-operating of impelling element; It also can be a button; This button with by the impelling element or by the afterbody coordination of impelling element, and with by impelling element or vertical or move at an angle by the afterbody of impelling element.And cocking mechanism 19 equally can with by the impelling element or by the coordination of impelling element afterbody, so that make cocking mechanism 19 and penetrated element or its afterbody pressure relief balance forcibly through pulling out in the impelling direction by the impelling element or by the afterbody of impelling element.

At Fig. 3, among Fig. 4 and Fig. 5, device is in different firing phases.

Cocking mechanism 19 has a protector 23, and this protector 23 has the effect that before taking from cocking mechanism, stops cocking mechanism 19 actions.

The handle 20 that rotates at transmitting site of throwing off from protector 23 has been shown in Fig. 3.Rotation at the axle 21 of pressing handle 20 and the cocking mechanism that withstands instrument through finger; Under the axle rotating conditions that the grooving of the sharp-pointed part 10 of grooving 22 heads was left in 18 minutes, instrument just begins to move in the impelling direction under the effect of the power that produces because of above-mentioned shell 9 and protuberance 7 difference in areas.

In Fig. 4, in case shell 9 was opened with protuberance in 7 minutes, the gas pressure in chamber 2 just acts on the above-mentioned shell 9 fully, and instrument just begins 2 acceleration along the chamber.Here, by incompressible material for example the bar empennage 11 processed of plastic cement play the part of the role of the constant compressor of the cavity volume that makes shell 9.

When instrument moved in chamber 2, the gas of the compression in bar 11 fell into chamber 15 along passage 14, in chamber 15, produced pressure.At this moment the inappreciable partial pressure of gas escapes in the atmosphere through passage 17.

In Fig. 5; When from chamber 2, being transmitted in the atmosphere instrument; Gas expands in chamber 15 and in shell 9, forms the chamber; Bar empennage 11 is released from shell 9, and the diameter 12 (the position A in Fig. 1) that this release is performed until the increase of bar 11 is because of till the internal diameter 13 (position 5 in Fig. 1) that reduces is when stopping to reduce.The part that head is sharp-pointed, shell 9 and the instrument formed from the bar empennage that shell is released are to target travel.-

Be in the increase that minimal compression gas exerts oneself through the situation of sealing device 8 seepages at the device that remains full of gas and be absolutely necessary even passage 17 is pulled deduction structure 19 for eliminating.If passage 17 the seepage gas pressure do not occur and descends, then since Compressed Gas through sealing device 8 seepages, the power that on shell 9, shifts out and thereby will increase and all one's effort when reaching projection, that is tens (reaching hundred) kilogram in the power of head.Under this condition, when attempting to launch, the not enough rotating lever 20 of the power of finger, so, pull the axis 21 of deduction structure and opened in 18 minutes with head 10 otch.

Because in device of the present invention, should make instrument reach fluid pressure balance, so that the unlatching power of trigger gear is comfortable to the user, promptly stowing pressure is unrestricted with corresponding muzzle energy in theory, and the strength of materials that only receives to be adopted limits.

Pneumatic gun post in inactive state has been shown in Fig. 6.The characteristic of this device is: be set forth in blade 25 fixing in the above-mentioned accompanying drawing with the mode of reproducing, this blade is fixed on the main body 1, if for example be necessary to reduce the volume of emitter, fixes with screw or key in order to extract blade 25 fast.

In Fig. 7, illustrated at shooting pneumatic gun post constantly, handle 20 makes instrument get back to the unlatching state, and instrument 26 leaves from main body 1 and in the groove 27 that forms at blade 25, moves.

The device of pneumatic shooting has been shown in Fig. 8, has comprised fixing blade 28 and additional blade 29.This blade 29 comes down to the variant of an instrument afterbody.

In Fig. 9, illustrated at additional blade 29 shootings pneumatic gun post constantly, this additional blade 29 has processes dovetail guiding protuberance 30 and along the cannelure 31 of response, this groove 31 forms swallow-tail form equally in fixed blade 28 sides.

On pneumatic weapon, big as far as possible weight should be arranged so that guarantee enough muzzle energy by impelling element (instrument); Because the weapon that kind unlike the gunpowder emission in pneumatic weapon reaches big muzzle energy by gathering way; But lean on its weight; The afterbody that utilizes band blade by the impelling element time, promptly heavier blade has increased the utilization ratio of the energy of gas filling.

Pneumatic gun post has been shown in Figure 10, has comprised that the main body 1 that has the chamber 2 of charging, plug 32 the insides that have ring packing packing ring 5 are equipped with the cannelure of flexible valve collar 5, this valve collar 5 cuts off the interconnection that is communicated with calibration ring 6.Form the chamber on the end face of the plug 32 in getting into chamber 2, the protuberance that has the shot block device 33 of the airtight seal 34 of ring-type gets in this chamber.Have the shell 9 of linking top airtight head 10; (this airtight head 10 has annular air sealing gasket 16), had by the shell 9 of impelling element and to distribute superincumbent entering in the end chamber of shot block device 33 and be upside down in by the annular air gasket 36 of impelling side.That is to say that the potted component of airtight sealing inflatable chamber is installed in by on impelling element or handle body or the shot block device body.

Remained in the main body 1 by means of cocking mechanism 19 by the impelling element.The diameter of shell 9 is identical with the area that end 9 is described.Have area that the protuberance of the cyclic sealing gasket 43 of shot block device has area less than shell 9 and end 35.Has under the big fluid pressure 37 hole in processing on the end 35.And processing has the hole of big fluid pressure 38 on shot block device 33; The effect in these holes is to be discharged into gas in the atmosphere; Because the gas leakage of contingent sealing ring 34 and 36; Gas leakage can interrupting device work, and show on the reinforcement that interrupts end 35 and being communicated with of shot block device 33 going up or show the power of unclamping that acts on the cocking mechanism 19 (be described in detail in the summary of the invention of beginning and describe).

Figure 11 shows under the state of opening cocking mechanism 19; Have head 10 (Figure 10) and begun in the shooting lateral movement by external surface area (area of being described with end 35 is identical) and the actuating pressure that difference in areas produced that protuberance had that has the shot block device 33 of sealing gasket 34 with the shot block device, the inflation pressure that this pressure equals in the chamber 2 multiply by above-mentioned difference in areas.

By the shell of impelling element along the chamber 2 when moving, shot block device 33 is connected with the end 35 of shell 9.

In Figure 12, illustrated when the end 39 in shot block device 33 arrival chambeies, shot block device 33 just stops, and opened with the shot block device in 33 minutes the end 35 of being penetrated the shell 9 of element, by the impelling element to target travel.

The pneumatic gun post that has cocking mechanism has been shown in Fig. 3, and this cocking mechanism is perpendicular to also being stoped possible moving under hold mode by impelling element mobile insurance device 41, and this protector 41 rotates with having on the spherical spring steady pin at axle 42.

In Figure 14, protector 41 lifts in the position that disengage button 40 keeps.

In Figure 15, protector 41 lifts, and button 40 is pressed, so that make button and withdrawed from the state that meshes with grooving 18 by the part of grooving 18 co-operatings of the head 10 of impelling element.

In Figure 16, grooving 18 withdraws from and button 40 engagements fully, is begun to be accelerated by the impelling element.

Pneumatic gun post has been shown in Figure 17; This device has the inflatable chamber 2 of decentraction (axle that promptly has dispersion) configuration and by the shell 9 of impelling element; And the sharp cutting edge 43 of additional blade; That is to say, will be by the relatively axle of the airtight inflatable chamber of the handle configuration of staggering of the axle of the element of impelling and its afterbody.The purpose of doing like this can reduce the size of the handle of device under the section and corresponding strength condition that keep fixed blade.
