  • II. Description of the Prior Art
  • Heretofore, it is known that the structure of the gas bottle powered toy guns are not available for game for their lethality, those toy guns need decompression valve connected to the high pressure gas bottle to lower the pressure of the gas bottle, that can increase shooting quantity with the same capacity of gas bottle and assure shooting force is within safety regulation.
  • However, referring to FIG. 5 and FIG. 6, the cross-sectional view of the whole body and the fixed pressure valve (the decompression valve of the present invention) of Taiwan listed pattern no. 568627 “Gas Decompression Device of Toy Guns”. The structure of the fixed pressure valve of the prior art is to have a bullet guiding slot 11 and a container 12 installed in parallel with the magazine 10, a decompression valve 20 is inside the container 12 to subdivide the container 12 into a gas bottle chamber 12 a and a decompression chamber 12 b, a control valve 30 is installed above the magazine 10, a high pressure gas bottle 40 is inside the gas bottle chamber 12 a, the high pressure gas bottle 40 connects to the decompression valve 20; the working principle is when the high pressure gas inside the high pressure gas bottle 40 enters the decompression chamber 12 b, the two sides 221, 222 of the plunger 22 inside the decompression valve 20 apply the inverse proportion of area verse pressure physical character to have the pressure equilibrium between both sides of the plunger 22 of the decompression valve 20, the area on the decompression valve 12 b of the plunger 22 has the larger area to have less pressure for less gas pressure to achieve decompression purpose. The defects of above structure is the known decompression valve a is immobile, the decompression effect is fixed; while application or testing, users find the gas pressure is too high or too low, the known prior art with fixed plunger 22 can not change or adjust the gas pressure entering the decompression chamber 12 b.
    • SUMMARY OF THE INVENTION
  • It is therefore a primary object of the invention to provide a gas decompression magazine of a toy gun that applies the decompression valve to adjust the gas pressure to make sure the high pressure gas inside the decompression chamber is in the best application range.
  • In order to achieve the objective set forth, a gas decompression magazine of a toy gun in accordance with the present invention comprises a bullet guiding slot and a container installed in parallel inside the magazine, a decompression valve is inside the container and subdivides the container into a gas bottle chamber and a decompression chamber, a control valve is on the top of the magazine, a gas bottle is installed inside the gas bottle chamber and connects to the decompression valve; the major character is: a plunger and a compression spring are installed in series inside the valve body of the decompression valve, then are threaded sealed by a cover on the top of the valve body; a bottle connector is on the bottom of the valve body; a small hole is on the wall of the valve body to interconnect the space above the bottle connector and the decompression chamber; the bottle connector connects to the high pressure gas bottle on the lower portion and pierces the high pressure gas bottle while connecting to release the high pressure gas; a top needle is on top of the gas outlet on the center of the bottle connector, then a threaded cover seals the top and has the top needle pass through the threaded cover and prop the plunger.
  • While application based on above structure, users can adjust the depth of the cover inside the valve body to change the distance between the bottom of the cover and the top of the plunger, the decompression strength of the compression spring in between changes, the shooting gas pressure after adjustment can meet the safety requirement.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
  • FIG. 1 is an assembly view of the present invention;
  • FIG. 2 is a perspective view of the present invention;
  • FIG. 3 is a cross-sectional view of an application of the present invention;
  • FIG. 4 is another cross-sectional view of an application of the present invention;
  • FIG. 5 is a cross-sectional view of the prior art;
  • FIG. 6 is a cross-sectional view of a further embodiment of the prior art.
    • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIG. 1 to FIG. 3 and FIG. 5, the parts with the same number tags are the same or similar parts with the prior art.
  • The present invention comprises a bullet guiding slot 11 and a container 12 installed in parallel inside the magazine 10, a decompression valve 20 is inside the container 12 and subdivides the container 12 into a gas bottle chamber 12 a and a decompression chamber 12 b, a control valve 30 is on the top of the magazine 10, a gas bottle 40 is installed inside the gas bottle chamber 12 a and connects to the decompression valve 20.
  • The major character is: a plunger 22 and a compression spring 23 are installed in series inside the valve body 21 of the decompression valve 20, then are threaded sealed by a cover 24 on the top of the valve body 21, a bottle connector 25 is on the bottom of the valve body 21; a small hole 211 is on the wall of the valve body 21 to interconnect the space above the bottle connector 25 and the decompression chamber 12 b; the bottle connector 25 connects to the high pressure gas bottle 40 on the lower portion and pierces the high pressure gas bottle 40 while connecting to release the high pressure gas; a top needle 252 is on top of the gas outlet 251 on the center of the bottle connector 25, then a threaded cover 253 seals the top and has the top needle 252 pass through the threaded cover 253 and prop the plunger 22.
