Abstract

The invention discloses an ejector special for an injector. The ejector for the injector is characterized by mainly comprising an ejection tube, a pushrod, a bowed frame, an elastic string, a finger lock triggering mechanism and a grab handle, wherein the pushrod is arranged in the ejection tube; a small section of half surface for assembling and disassembling the injector is arranged on the rear part of the ejection tube; a section groove penetrating through the two sides of the ejection tube is also formed in the middle part of the ejection tube; the bowed frame is crosswise and fixedly connected with the ejection tube; the finger lock triggering mechanism and the grab handle are also arranged on the rear part of the ejection tube.

Description

Syringe special bullet emitter

Technical field

The present invention relates to a kind of catapult-launching gear, particularly a kind of catapult-launching gear for launching syringe, belongs to technical field of medical instruments.

Background technology

In field of medical technology, often will carry out medication injections to some animals, but some animal is very violent or quick, always keeps remote with the mankind, adopts general hand-held injecting method to be impossible success or the thing of danger close.Launching injection is that people can at a distance to the method for animal liquid medicine injection, current people have employed a lot of long distances and launch syringe method, syringe emitter made by some use Compressed Gas rifles, this Compressed Gas rifle structure is very complicated, profile is similar to military firearms, be easy to cause misunderstanding when carrying out therapeutical operation in the wild, and the power of this rifle is excessive, likely animal is damaged, also likely put into other than syringes class projectile by lawless person and carry out attacking crime behavior.Another kind adopts spring to launch injection device, and equally, spring ejector profile feature still cannot be distinguished with formal military firearms.Launch injection device as therapeutical, not only will reach remote injection effect accurately, can not also injure animal, it is belong to general civilian catapult-launching gear that outer shape also must allow people understand at a glance.

Summary of the invention

In order to the shortcoming that the shape overcoming compressed air type or spring distance transmission syringe is similar to military firearms, and it is excessive to launch power, be easy to the shortcoming injuring animal, a kind of device for distance transmission injection animal of my invention: syringe special bullet emitter, this device has and launches injectability at a distance accurately and effectively, and this planting unit has the arc opened, profile and military firearms phase difference are comparatively large, carry out medical procedures in the wild and do not cause misunderstanding accident.

Syringe special bullet emitter taked technical scheme of dealing with problems is: syringe special bullet emitter primarily of an ejection guns, arciform frame, elasticity string rope, push rod, refer to buckle trigger mechanism, hold handle and form, there is a push rod ejection guns inside, ejection guns also have one section of groove pass through both sides, ejection guns rear portion has a bit of half to lack face for filling imperial syringe, arciform frame and ejection guns interconnection, two of elasticity string rope connect arciform frame two, to be middlely connected with push rod, refer to that button trigger mechanism is arranged on the rear portion of ejection guns.

Syringe special bullet emitter relies on push rod movable propelling in ejection guns to launch syringe, and the movable kinetic energy of push rod in ejection guns comes from the energy of the elastic-restoring force release that elasticity string rope provides.We are according to the gunnery of bow and arrow, and in the arrow movement locus of bow and arrow, increase a trajectory, this trajectory is exactly ejection guns.Had the support of ejection guns, we can put the syringe than long arrow much shorter in ejection guns into and launch at a distance, and launch trigger mechanism and can be arranged on ejection guns, make people can carry out the control of launching.

Syringe special bullet emitter relies on ejection guns to carry out trajectory to syringe and controls to launch, imperial for the ease of filling, we open cross-sectional for ejection guns rear portion a bit of, and this is a bit of can just fill in cylinder syringe, this completes the setting that injection tube can be loaded in trajectory cylinder.But, elasticity string rope is connected with push rod, push rod is movable in ejection guns, elasticity string rope but will pass through barrel, stretch out two ends and connect arciform frame, like this, the tubular structure closed also counteracts that the motion of elasticity string rope, we must output groove in the two sides of ejection guns and pass through cylindrical shell, but the length of this groove also can only be the part in the middle part of cylindrical shell, can not be whole, to maintain the tubular feature of ejection guns.

The beneficial effect of syringe special bullet emitter is: syringe special bullet emitter utilizes the catapult-launching gear of arc to coordinate the design of the trajectory of cylinder, not only outer shape is different from military firearms, also injury can not be formed to people and animals in ejection force, and launch accurately, success rate is large, is best civilian catapult-launching gear.

Accompanying drawing explanation

Fig. 1 is the arciform frame of syringe special bullet emitter and ejection guns cross facet sectional median plane structure chart.

Fig. 2 is the outer surface figure after the syringe special bullet emitter side of Fig. 1 turns 90 degree of angles.

In figure, 1. ejection guns, 2. arciform frame, 3. elasticity string rope, 4. push rod, 5. syringe, 6. sight, 7. half face, 8. refer to buckle trigger mechanism, 9. groove, 10. hold handle.

Detailed description of the invention

Below in conjunction with accompanying drawing, further implementation is done to syringe special bullet emitter.

Fig. 1 is arciform frame and the ejection guns cross facet middle section structure chart of syringe special bullet emitter.In Fig. 1, ejection guns (1) postmedian is equipped with syringe (5), and syringe (5) rear portion heads on push rod (4), the company's of tying up elasticity string rope (3) on push rod (4).Arciform frame (2) in Fig. 1 and ejection guns (1) intersect fixing, but arciform frame (2) does not pass through ejection guns (1), do not affect in ejection guns (1) smooth and easy.Two that arciform frame (2) opens is connected with elasticity string rope (3), and elasticity string rope (3) is in straining at state, and the elasticity size of elasticity string rope (3) determines the power of launching of whole ejector.

If we are the device of Fig. 1 rollover 90 degree, to observe the structure of this syringe special bullet emitter better.Some important feature that Fig. 2 energy exploded view 1 can not be shown: ejection guns (1) is not complete, not only latter half of have a bit of cutting half to become half face (7), can just fill in syringe (5) etc. to be launched; The imperfect of ejection guns (1) is also that its mid portion also has one section of groove (9) to pass through both sides, and the effect of this groove (9) is to allow elasticity string rope (3) stretchy push rod move in ejection guns (1).Be equipped with below ejection guns (1) rear portion in Fig. 2 and refer to button trigger mechanism (8) and hold handle (10), top is also provided with sight (6), using this device to launch syringe with using gun to shoot is the same gesture actions, launch really facilitate accurate, but people from side can find out that this is a professional ejector at a glance.

Claims

1. syringe special bullet emitter, it is characterized in that: syringe special bullet emitter primarily of an ejection guns, arciform frame, elasticity string rope, push rod, refer to buckle trigger mechanism, hold handle form, a push rod is had in ejection guns, ejection guns also have one section of groove pass through both sides, ejection guns rear portion also has a bit of half to lack face for filling imperial syringe, arciform frame and ejection guns interconnection, two of elasticity string rope connect arciform frame two, to be middlely connected with push rod, refer to that button trigger mechanism is arranged on the rear portion of ejection guns.
