Abstract

The utility model relates to a tool for fishing (can be used for hunting), whose shape is similar with a short gun, thus naming a hunting rifle for fishes. The utility model is characterized in that powder and compressed air are not needed, according to the elastic force of hard springs which is especially made, and a steel arrow whose top end is sharp and has barb thorns and whose tail end has nylon ropes is rapidly sent out. For increasing elastic force, increasing sending speed and shortening the body of the rifle, the utility model adopts three stage ejecting modes which eject the springs in the automatic relaying mode in sequence from outside to inside via three layers of steel tubes, three layers of springs and three times of strain, and last stage of springs sends the steel arrow out of a bore. After the steel arrow penetrates into preys, the ropes are furled, and the preys are hunted.

Description

Three-stage catapult hunting rifle for fish

The utility model is a kind of fishing instrument of (also can be used for hunting), and so the likeness in form short arm is the name hunting rifle for fish.Its adopts the method for shooting, makes the top sharp keen and have delavay raspberry herb, tail end system and have the steel of nylon rope to vow to thrust fast in the body of hunting thing, draw rope then in and prey can be caught.

At present, harpoon traditional, that fall behind is still used in the fisherman's fishing on rivers,lakes and seas bank and the island, the dart fishing, and not only cast is short, and speed is slow, and adjusting to changed conditions property is poor.This hunting rifle for fish can replace harpoon, improves fishing efficient, increases the enjoyment of fishing.

Though the hunting rifle for fish of submerged type and other type comes out already, because of its manufacturing process complexity, costs an arm and a leg, and mostly is the rifle shape again, it is very not convenient to use, so can not promote for a long time.This shotgun is compared with it, and it is not high to have manufacture process requirement, the body of a gun short (about one chi), (about two kilograms) in light weight, carries and many advantages such as easy to use.

Now, the structure and the using method of this three-stage catapult hunting rifle for fish of having succeeded in developing and having carried out effectively testing for too much time are done with introduction particularly according to accompanying drawing:

Fig. 1 is hunting rifle for fish side longitudinal sectional drawing of (when promptly not using) under non-energy storage state.

Fig. 2 is hunting rifle for fish side longitudinal sectional drawing of (when promptly being triggered at any moment) under the energy storage state.

Referring to Fig. 1, the short and thick steel pipe of one-level (1) and front and back pikestaff (2), (3) are made as one, and there is one section internal diameter the rear end of pipe than front little (thicker), form jut (4).Fix a recurvate little iron lance (5) respectively (scheming medium and small iron lance shows with double dot dash line in the outer symmetrical both sides of this section pipe.Only mark one), be equipped with gunlock in the back handle front upper place of rifle, gunlock is made up of plate machine (6), top spring (7) and push rod (8).Push rod (8) is inserted in the boring of pipe (1).One-level spring (9) (with representing than great circle of the band hatching that equidistantly distributes) is housed in the pipe (1), and the anterior internal diameter of spring external diameter and pipe (1) matches, and spring inside diameter equates with the internal diameter of pipe (1) than thickness portion.Spring has half to put in the pipe (1) approximately, and half exposes outside the pipe, when its full compression, can all put in the pipe.The one-level spring housing is on its corresponding secondary steel pipe of external diameter (10), one the becket of projection (11) and (12) (ring (12) and pipe (10) bonnet are made as one) towards periphery fixed at the two ends of pipe (10) respectively, and these two rings are in order to prevent that spring (9) from slipping out and preventing to manage (10) and spring (9) from pipe (10) and deviating from and establish from manage (1).The suitable two-level spring of thickness (13) (with representing than small circle of the band hatching that equidistantly distributes) is housed in the secondary steel pipe (10), spring (13) is enclosed within on the grade III steel pipe (14), the front end of pipe (14) is fixed with piston (15), piston nose is fixed with resilient steel clip (16), the afterbody of pipe is fixed with pulling plug (17), and three grades of springs (18) are housed in the pipe.

Introduce the stored energy operation methods at different levels of hunting rifle for fish below: referring to Fig. 2, muzzle is withstood on the ground or the deck of boat, left side hand-held gun pull end, handle after the right hand-held gun, incline the power of whole body to pressing down one-level spring (9), jut (4) in the steel pipe (1) promotes spring to lower slider, and the front end of pipe (1) is contacted with becket (11), and spring all is compressed and enters in the pipe.At this moment slide along the outer wall of pipe (10) in the top of gunlock push rod (8), moves on to aperture (19) bottom on the pipe (10) just, creeps in the hole under the promotion of top spring (7), and spring (9) is blocked, and can't uphold.This has just finished the operation of hunting rifle for fish one-level energy storage.

Then, handle is to pressing down after the right hand-held gun, left index finger and middle finger catch on pulling plug (17) and firmly upwards carry, two-level spring (13) is compressed, when the bonnet of pipe (10) is exposed in two grooves of symmetry (20), (20 ') on the pipe (14), two cross sections up and down of special clamping bar are rectangular metallic rod (21), (21 ') on the bonnet, in the embedded groove, spring (13) can't be upheld under spring (22), (22 ') pulling force effect.This has just finished the operation of hunting rifle for fish secondary energy storage.(Fig. 2 lower right corner is shown, is the rearview of special clamping bar device on pipe (10) bonnet, and the arrow indication is the position of little iron lance bump everywhere.〕

At last, steel is vowed in (23) insertion muzzle, steel is vowed that the tip withstands on the fixture, push hard rifle, steel is vowed three grades of springs is compressed to the interior rear portion of pipe (14), at this moment two symmetric windows (24), (24 ') on steel is vowed are clamped by resilient steel clip (16), and spring (18) can't be upheld.This has just finished three grades of stored energy operations of hunting rifle for fish.

Pull gunlock during shooting, push rod (8) moves down, and extracts the aperture (19) from pipe (10), and spring (9) fierce extension out of hand is rapidly moved pipe (10) forward.When back ring (12) bumped against pipe (1) rear portion soon, little iron lance arrived in the nick of time, and clamping bar (21), (21 ') was rushed open (even the distance between two clamping bars enlarges), and disengaging notch (20), (20 ') cause that two-level spring upholds fast.When pulling plug bumps against on pipe (10) bonnet soon, piston resilient steel clip in front (16) has also bumped against just at the same time and has been fixed in pipe (10) front port, that have central aperture, vertical section is on the iron wedge (25) of isosceles trapezoid, the steel double-layered quilt hits and opens, cause that again three grades of springs uphold rapidly, make steel vow to resemble like lightning and penetrate from muzzle.

Here introduce the connecting method of steel resultant nylon rope again.If rope is fastened the neck of vowing at steel, after steel is vowed and is penetrated, the stressed meeting of front end somersaults; If rope is fastened the afterbody of vowing at steel, steel vows when putting into bore that one section rope also will be along with putting into bore simultaneously, and so not only friction is big, and rope is very fast to be rubbed, and rope also can be blocked by the iron wedge sometimes.Facts have proved, adopting the Movable loop connecting method is the best way, be about to rope and be fixed on the neck that steel is vowed earlier, again the rope bifurcated is reserved from steel and vowed that neck is after the length of afterbody, tie up to respectively in the groove that is enclosed within the symmetrical both sides of the live metal collar (26) on the steel arrow, then two fens ropes are prolonged one section unification backward, connect mutually with long longline (27).Like this, when steel was vowed in bore, Movable loop was positioned at steel and vows neck, and rope is all in the outside of bore; When steel vow to penetrate, the collar was because before inertia stops not, and steel washes away before vowing in the hoop, ring got rid of at steel vow afterbody, and the back is being pulled rope and steadily advanced, as the straight target of speeding of meteor with the long-tail crust.

Make in the accurate embedded groove of clamping bar in order to make the gunlock push rod accurately enter the hole neutralization, must not rotate mutually between each steel pipe, the device that this just needs two anti-rotation of peace does not mark among the figure.

In addition, use in order to realize a rifle more, make hunting rifle for fish become the transmitters of using more,, keep fixedly two corresponding bolts of iron wedge as long as the iron wedge at muzzle place is unloaded, (the symmetrical both sides of wooden handle are carved two dark skewed slots from top to bottom but this rifle is with regard to the emission band wooden handle, skewed slot differs 90 ° of skewed slots from beginning to end and aims at bolts, and bolt is embedded, just can be with in the wooden handle rotation threading bore) steel pricker or steel fork, and awl (fork) rotation is advanced, play the effect that rifling makes the bullet rotation.If the pre-installed rubber ball of going up of wooden handle is launched, hunting rifle for fish is used as bodybuilding equipment on sports ground.

In sum, the characteristics of this hunting rifle for fish are, do not use gunpowder and compressed air, by the elastic force of special hard spring steel are vowed fast and penetrate. In order to increase elastic force, improve firing rate, shorten the body of a gun, it adopts the mode of three-stage catapult, be that the rifle body is made of compound steel pipe, three layers of spring, shock mount, spring interpolation steel pipe, overlap assembly, layer by layer identical in the steel pipe, three times firmly with spring-compressed (or pulling open), make hunting rifle for fish be in energy storage state, respectively stretching with push rod, clamping bar and steel clamp control spring. Touch gunlock, extract push rod, two, three grades of springs of first order spring promotion and steel are vowed travel forward simultaneously; When the fast end of motion, clamping bar is backed down, and second level spring then promotes three grades of springs and steel arrowhead preacceleration campaign; When the fast end of motion, steel clamp is opened, and third level spring then only promotes steel arrow itself again and again accelerates to travel forward. Be shot, can moment cause springs at different levels from outer to inner successively automatic relay launch, the afterbody spring vow to penetrate bore with steel, still launches an artificial satellite generally like three-stage rocket.

Use the method for this hunting rifle for fish shooting, the gunning of presenting arms pushes away the rifle gunning and strides that to push away the rifle gunning multiple, adopts different gunnery techniques, can make same gun have different firing rates and range.
