Description

[Detailed description of the device]

[0001]

This invention relates to a gas pressure reducing device for a toy gun. More specifically, the present invention relates to a gas pressure reducing device for a toy gun that reduces the pressure of gas supplied to a toy gun that uses a pressure of gas to fire a bullet such as a BB bullet.

[0002]

2. Description of the Related Art Conventionally, Freon gas has been used as the gas used in toy guns.

[0003]

[Problems to be Solved by the Invention] However, although the use of CFCs for other gas is being considered recently, CFCs are also used in toy guns that fire BB shells at gas pressure. There was a problem that the performance deteriorated due to the decrease in pressure during use, and it was necessary to replace the magazine to compensate for it and wait until the pressure was restored.

Carbon dioxide gas, when used as a gas for a toy gun by filling it in a gas tank, can have a pressure about 10 times that of fluorocarbon gas. Therefore, if CFCs were used to fire, for example, 60 shots, the pressure of the gas would change from the first shot to the 60th shot, but if carbon dioxide gas was used, the first to 60th shots would occur. The same pressure can be maintained.

However, since carbon dioxide gas has a high pressure, it is necessary to reduce the pressure before use.

[0006]

[Means for Solving the Problems]

A gas tank installed in a toy gun, a pressure reducing device having one end attached to a gas discharge port of the gas tank, and a discharge valve mounting portion attached to the discharge valve attached to the other end, and one end attached to the pressure reducing valve mounting portion. A gas pressure reducing device for a toy gun, which is attached to the other end of the gun engine part and is connected to a gun engine part to supply a gas.

Providing

[0009]

The gas supplied from the gas tank enters the decompression device, is decompressed, enters the barrel base through the discharge valve, and fires a bullet.

The BB magazine 21 has a cylindrical shape, and when the magazine 12 is attached to the toy gun body 11, the upper opening is located in the chamber 13 of the toy gun body 11. The release valve 22, the decompression device 23, and the carbon dioxide gas cylinder 24 are sequentially installed from the top side by side with the BB shell magazine 21. When the magazine 12 is installed in the toy gun body 11, the release valve 22 is installed in the toy gun body 11. It is attached to the gas inlet 14 provided. The carbon dioxide gas cylinder 24 is filled with liquid or gaseous carbon dioxide gas.

The pressure reducing device 23 is attached to a lower portion of the discharge valve 22. In FIG. 3, reference numeral 31 is a body of the decompression device 23. The body 31 has a substantially cylindrical shape with an opening. 32 is a packing holder, 33 is a needle, and 34 is a cylinder packing. The needle 33 is provided with a hole in the center in the longitudinal direction, and the tip thereof is provided so as to project into the hollow portion 51 of the body 31, and is installed substantially parallel to the longitudinal direction of the body 31. The cylinder packing 34 is mounted in a disk shape so as to surround the tip of the needle 33. The cylinder packing 34 is supported by the packing retainer 32 on four sides from four locations. A pressing nut 35 is provided with a hole at the center. The retainer nut 35 is attached to the body 31, supports the packing retainer 32, and attaches the base of the needle 33 to the hole via the O-ring 49.

Reference numeral 36 is a filter. The filter 36 is attached to the hole of the holding nut 35 at the base of the needle 33. Reference numeral 37 is an O-ring mounted between the press nut 35 and the inner peripheral surface of the body 31. A sheet retainer 39 is installed on the bottom portion 50 of the hollow portion 51 provided in the body 31 at the back of the retainer nut 35.

Reference numeral 38 is a primary valve spring, and 41 is a primary valve pin. The primary valve pin 41 is supported by the O-ring 40 and penetrates the bottom portion 50 of the hollow portion 51, and one end of the primary valve pin 41 is urged toward the bottom portion 50 by the primary valve spring located in the filter 36. Reference numeral 57 is a ventilation path that connects the installation space of the primary spring 41 and the side surface of the hollow portion 51.

Reference numeral 52 is a discharge valve side body. The discharge valve side body 52 has a hollow portion 53 and is fitted into the bottom portion 50 of the body 31. From the bottom of the discharge valve side body 52, a hollow cylindrical projection 54 is provided so as to project toward the end of the primary valve pin 41.

Reference numeral 44 is a piston. The piston 44 has a bowl shape and has a bottom portion penetrated by the protrusion 54. Reference numeral 42 denotes a piston O-ring A, which is mounted around the opening of the piston 44 and makes close contact with the inside of the discharge valve side body 52. 43 is a piston rod. The piston rod 43 is installed inside the piston 44, penetrates the protrusion 54, and is installed at a position where the air passage 55 is displaced from the portion corresponding to the primary pin 41. The side of the needle 33 of the piston rod 43 contacts the tip of the primary valve pin 41. Reference numeral 45 is a piston O-ring B, which is installed around the protrusion 54 of the piston 44 at the bottom of the piston rod 43.

Reference numeral 46 is a secondary valve spring. The secondary valve spring 46 has one end attached to the bottom of the hollow portion 53 and the other end attached to the piston 44, and urges the piston 44 toward the needle 33 side. Reference numeral 47 is a case, and 48 is an outer case. Reference numeral 56 denotes a discharging device mounting portion, which is provided in a concave shape at the base of the protrusion 54, and the discharging valve 22 is attached.
