Abstract

The invention relates to a paper bullet gun which is a toy. A tubular gun barrel is made of plastic or metal. The paper bullet gun is provided with a bar-shaped push rod. The caliber of one end of a gun bore with two opening ends is large and is gradually reduced toward the other end of the gun bore. Firstly, a wetted small paper filler A is filled into the end with the large caliber and is pushed to the end with the small caliber by the push rod, wherein the length of the push rod is less than that of the gun bore, so that the small paper filler A is retained at an orifice at the end with the small caliber to seal up the orifice; then another wetted small paper filler B is filled into the end with the large caliber and is rapidly pushed to the end with the small caliber by the push rod; and the small paper filler A which seals up the orifice at the end of the small caliber is fired by the compressed air.

Description

The word bomb rifle

Technical field

The present invention is a kind of toy.

Background technology

At present, the pneumatic gun of people's use is that the kinetic energy that utilizes compressed air to produce is launched plumb.The pneumatic gun volume is big, complex structure, and lethality is big, is not suitable for children and plays, neither a kind of toy.

Summary of the invention

For overcoming the above-mentioned shortcoming of pneumatic gun, the present invention provides a kind of word bomb rifle, its simple structure, and volume is little, and no lethality is a kind of toy that is fit to children.

The technical solution adopted for the present invention to solve the technical problems is: with plastics or metal is that material is processed the tubular gun barrel, and length is 0.10 meter to 0.20 meter, 0.01 meter to 0.03 meter of external diameter.Bore be both ends open, cross section is circular pipeline, port footpath is bigger, is 0.005 meter to 0.008 meter.Its bore successively decreasing gradually to the other end, make other end bore less, is 0.004 meter to 0.007 meter.Other is furnished with a cross section and is bar shaped push rod circular, that diameter is slightly less than (little 1 millimeter) bore lowest calibre, and the bar shaped push rod is processed with metal or plastics, and length is slightly less than bore length (little 5 millimeters).Push rod is connected with portion of the handle, is convenient hand-held push rod, and portion of the handle adds greatly cylindrical, and diameter equates that with the gun barrel external diameter length is 0.02 meter to 0.10 meter.Earlier soak paper during use, rub into little group, make little spitball A can just fill in bore heavy caliber one end; Be pushed into a small-bore end with push rod; Because push rod length is less than bore length, spitball A rests on a small-bore end mouth of pipe place, and this moment, little spitball A sealed a small-bore end.Go into same little spitball B at heavy caliber one end plug again, be pushed into a small-bore end quickly with push rod, air is compressed between two spitballs at this moment, and air compressed was launched the little spitball A of front when push rod was pushed into the end.

The invention has the beneficial effects as follows: volume is little, no lethality, and simple structure, easy to use, there is the sound to send, be fit to playing by children.

The specific embodiment

In Fig. 3, Fig. 4, R1=R3, numerical value are 0.01 meter to 0.03 meter, and R2 is 0.005 meter to 0.008 meter, and R4 is 0.004 meter to 0.007 meter; In Fig. 5, a is a push rod length, and its numerical value is 0.095 meter to 0.195 meter, and c is a rod diameter, and its numerical value is 0.003 meter to 0.006 meter, and b is a push rod portion of the handle length, and its numerical value is 0.02 meter to 0.10 meter, and d is a push rod portion of the handle diameter, d=R1=R3; In Fig. 6, e is a gun barrel length, and its numerical value is 0.10 meter to 0.20 meter, f1=f2=R1=R3.

Claims

1. one kind tubular word bomb rifle is characterized in that: the little spitball made from l Water Paper is launched with push rod as bullet.

2. word bomb rifle according to claim 1 is characterized in that: push rod length is slightly less than bore length, and bore is that cross section is circular pipeline, both ends open, and port footpath is bigger, is decremented to the other end gradually, and other end bore is less.
