Abstract

The utility model mainly relates to a bullet used for an air gun. The air gun bullet of the prior art is made up of metal, and thus the bullet has the disadvantages of high manufacturing cost, serious pollution, and poor flying state. The bullet of the utility model is formed by that a bullet shell made up of polymer materials is used, and the tail of the bullet shell is a hollow structure, and a weight core which is made up of materials, such as steel, or iron filings, or concrete, etc., to be matched with the bullet shell. The outer surface of the bullet shell is provided with a longitudinal wing. Thus, the flight stability is raised, precious lead resources is saved, pollution does not have, the flight weight of the bullet can be regulated, and optimum flight state can be obtained.

Description

Plastic bullet of air gun

The utility model relates generally to the pneumatic gun bullet, promptly makes plumb with metallic lead.

The pneumatic gun bullet of prior art is metallic lead and makes.Along with development and national economy, industrial some field, as: industries such as storage battery, cable, nuclear power, military project are increasing to the demand of metallic lead, and the raising of living standards of the people also tends to variation to the requirement of amusement, practices shooting with pneumatic gun after the work-break and hunts keeping tensions down psychology, will increase considerably needs to plumb, can cause show business and industrial production to strive the situation of resource undoubtedly, give original lead resource, cause nervous more situation with regard to few China.The lead contamination environment constitutes the harm this point to human body and is confirmed by medical science.Thereby in the producing and selling of plumb and in use, direct contactee is worked the mischief.And the plumb price is higher, and flight quality is relatively poor.Lead is used for making the bullet that pneumatically promotes, and mainly is the sealing of considering it, does not hinder bore.Just because of this, it also has many weakness that are difficult to overcome, and mainly is that machining shape is irregular, sealing is not good enough, the density of material dissymmetry, and center of gravity reach etc., the two big fundamentals that these factors have directly influenced the plumb shooting are surely, far.Thereby its penetration power also is subjected to the restriction of material hardness.Address these problems, must select new material and new structure.

The purpose of this utility model just is a kind of aboundresources is provided, and pollution-free, price is low, and human body is not had harm, and flight quality is good, and outward appearance can add decoration, and can adjust the plastics pneumatic gun bullet of weight as required.

Shell case of the present utility model has adopted macromolecular material, and the counterweight core adopts iron and steel or iron filings or concrete and other material, and both combine bullet.Body is cylindricality and other shape behind sphere, cylindricality, taper, the inner cone; The afterbody of shell case is a hollow structure, and has a counterweight core to cooperate with it, an assembled formation.Shell case adopts macromolecular material to make; Vertical missile wing is arranged on the outer surface of shell case; Fluted or fin on the surface of the afterbody hollow space of shell case, and its axial length is long greater than the counterweight core.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a cutaway view of the present utility model;

In Fig. 1, the 1st, guide part, it adopts the streamlined structure of arc transition, to reduce the air drag in the bullet running; 2 is sealing, it is the circumference seamed edge in the tail protrusion of shell case 3, to guarantee the sealing of bullet and bore, vertically missile wing 4 can improve the stability in the bullet flight course, adapting to machining accuracy, and can reach the purpose of economical with materials, missile wing 4 is on the outer surface of shell case, evenly distributing, is 3 at least.The 5th, the counterweight core can be adjusted its flying weight, reaches the state of flight optimization.

The utility model compared with prior art has:

1, economize on resources, cost is low; With material 5 grams, the material of counterweight core very easily obtains approximately for per hundred of the shell cases of plastics pneumatic gun bullet, so its price is well below the price of plumb, and consumer Geng Yi accepts.

2, because its shell case and counterweight core do not have non-ferrous metal,, in its producing and selling and use, can reduce some expenses so there is not pollution.

3, can select different counterweight cores, thereby its center of gravity be reasonable according to different shooting requirements, because the good seal of plastic ball shell and bore, frictional force is little, has missile wing to guarantee stability in its flight course again, so flying quality is good, the shooting average height, distance, penetration power is strong.

4, the surface of plastics pneumatic gun bullet can make shades of colour, helps distinguishing, also helps improving user's interest.

Embodiment 1:

Shell case adopts vinyon, use the injection moulding one-shot forming, its diameter is 4.5mm, and long is 6.0mm, the diameter of afterbody hollow part is 3.0mm, long is 4.0mm, and the missile wing on the shell case outer surface has 9 for being symmetrically distributed, the diameter of its sealing is 5.0mm, the counterweight core adopts scrap iron, and its diameter is 3.0mm, the long 4.0mm of being, its weight is identical with existing plumb.

Embodiment 2:

Body adopts a compression moulding of mixture of polyvinyl chloride and iron filings, and shape is with existing rifle bullet bullet, and its length is 5,5mm, and tail diameter is 4,5mm, and its weight is identical with existing plumb.

Claims

1, a kind of plastics pneumatic gun bullet, it is characterized in that: vertical missile wing 4 is arranged on the outer surface of shell case 3, and the afterbody of shell case 3 is a hollow structure, and has a counterweight core 5 to cooperate with it.

2, plastics pneumatic gun bullet according to claim 1 is characterized in that: shell case 3 is to adopt macromolecular material to make, and it is iron and steel or iron filings or concrete and other material that counterweight core 5 has adopted.

3, plastics pneumatic gun bullet according to claim 2, it is characterized in that: the vertical missile wing on the outer surface of shell case 3 is more than three or three.

4, plastics pneumatic gun bullet according to claim 2 is characterized in that: fluted or fin on the surface of the afterbody hollow space of shell case, and its axial length is long greater than the counterweight core.
