BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure adjusting device for a pressurized air toy gun capable of firing a bullet at a speed within a safety standard by using a gas instead of Freon gas for an air toy gun. is there.

[0002]

2. Description of the Related Art Conventionally, a commercially available chlorofluorocarbon gas has been refilled in a magazine or a cartridge in an air toy gun body, and a gas that has been naturally vaporized has been hit by hitting a discharge valve to discharge the gas and fire a bullet.

[0003]

However, in recent years, the use of CFCs has been restricted due to pollution due to air pollution, and CFCs are affected by the outside air temperature, which causes variations in pressure. Therefore, technological development to replace this is required.

However, a gas cylinder filled with, for example, carbon dioxide gas other than Freon gas is usually about 60 kg / cm.
The carbon dioxide gas was contained at a gas pressure of 2, and the gas pressure was too high to be used.

The pressure adjusting device for a pressurized air toy gun according to the present invention is intended to solve the above-mentioned drawbacks of the conventional example.
An object of the present invention is to provide a compact pressure adjusting device for a pressurized air toy gun which can be incorporated in a magazine or a gun main body so that a bullet can be fired using carbon dioxide gas.

[0006]

A pressure adjusting device for a pressurized air toy gun according to the present invention is a pressure adjusting device for firing bullets of an air toy gun, such as carbon dioxide gas in a magazine or a gun body. It is characterized in that a gas cylinder having a high gas pressure can be used as a substitute for CFC gas by connecting it to a discharge valve via a micro regulator.

According to the present invention, an ultra-compact regulator has a cylindrical regulator body, an inner cylinder having a gas passage formed in multiple stages so as to be fitted into the regulator main body, and the diameter of which is gradually increased, and an inner cylinder. An opening for releasing the gas passage at the tip is formed on the side surface, and a head having packing on the end surface and a spring holding portion on the outer circumference of the inner cylinder are provided, and the spring holding portion forms a spring between the inner cylinder and the inner cylinder. It is also characterized in that a small hole is formed in a partition wall which is interposed and provided at the back of the partition wall, and a gas supply unit for mounting a gas cylinder made of carbon dioxide or the like is provided across the partition wall.

Moreover, the ultra-compact regulators are arranged in one or two stages, and the carbon dioxide gas primary side pressure is 60 kg / cm2.
Is also reduced to a secondary side set pressure.

Further, the secondary side pressure is determined in proportion to the spring pressure contained in the microminiature regulator, and the installation location of the spring is very small due to the small size of the microminiature regulator. It is a structure that a spring with a thick wire diameter cannot be installed, and it will not exceed the set pressure, and if the spring is weak, it will fall below the set pressure, so it has a very safe structure. This is one of the features.

Further, by adopting a piston mechanism, the responsiveness to pressure fluctuation is good and a stable pressure can be obtained.

The collar and the micro regulator are not disassembled by fitting a square or round C ring into the inner groove provided between the inner cylinder and the discharge valve via the collar to prevent the inner cylinder from coming off. It is also a feature that it becomes possible.

[0012]

According to the pressure adjusting device for a pressurized air toy gun of the present invention, the pressure for projecting a bullet can be changed from the conventional CFC gas to carbon dioxide gas or the like, and the CFC gas is used to project a bullet. Since the gas pressure is more stable than when it was used, you can enjoy a good feeling with little variation in bullet velocity.

Further, the pressure adjusting device for a pressurized air toy gun according to the present invention is very useful as a countermeasure against the problem of air pollution due to CFC gas, which is a major social problem.

Of course, since the secondary side pressure is determined in proportion to the spring pressure built in the microminiature regulator, by adjusting the spring pressure of this spring, it is possible to adjust the pressure more than necessary. Therefore, it is possible to provide a pressurized air toy gun having a very safe structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pressure adjusting device for a pressurized air toy gun according to the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of the microminiature regulator in a closed state. The regulator body 1 has a cylindrical shape,
An inner cylinder 2 having a multi-staged gas passage 3 that is fitted into the regulator body 1 and is formed so that its diameter increases in sequence, and an opening 5 that opens the gas passage 3 at the tip of the inner cylinder 2 is formed on the side surface. And a head 4 having a packing 6 on the end face. Inner cylinder 2 is regulator body 1
It is configured to slide inside. Reference numeral 7 is a discharge valve provided on the side of the regulator body 1 opposite to the inner cylinder 2.

Reference numeral 9 denotes a spring holding portion. The spring holding portion 9 is housed inside (rear) of the inner cylinder 2 in the regulator main body 1, and is fitted into the outer circumference of the inner cylinder 2 to be connected to the inner cylinder 2. The spring 10 is interposed between them. A small hole 11 is formed in the inner partition wall. A gas supply unit 12 for mounting a gas cylinder 8 made of carbon dioxide gas or the like is provided on the back side of the partition wall. The gas supply unit 12 is provided with a pin 13 for making a hole in the gas cylinder 8 to let out the gas.

Reference numeral 14 is an inner groove provided between the inner cylinder 2 and the discharge valve 7, and is used to prevent the inner cylinder 2 from coming off by fitting a rectangular or round C ring 15 therein. The rectangular or round C ring 15 is pushed into the regulator body 1 while being mounted on the collar 16 and is positioned with its diameter expanded at the inner groove 14 portion.

The small hole 11 functions as a valve by repeating the operation of pressing the small hole 11 against the packing 10 due to a change in gas pressure. That is, small hole 1
When the sum of the sectional pressure A of 1 and the spring pressure B of the spring 10 is smaller than the sectional pressure D of the gas passage 3, the state is closed.

A + B <D ------------------- Closed FIG. 2 shows an open state, and the sum of the sectional pressure A of the small hole 11 and the spring pressure B of the spring 10 is the sectional view of the gas passage 3. When the pressure is higher than the pressure D, the inner cylinder 2 is pushed up at this time, and gas flows from the gas cylinder 8 punched by the pin 13 from the primary side to the secondary side as indicated by an arrow (dashed line). Then, the discharge valve 7 is opened and the gas is discharged.

A + B> D -------------- FIG. 3 shows that the pressure on the primary side is so strong that the pressure cannot be reduced to the specified pressure by the first stage of the pressure reducing device, and even if the rate of continuous firing is high. In the case of supplying a more stable pressure, the pressure is reduced in two stages. In this case, the pair of regulator mechanisms 21 and 22 having the above-mentioned configuration are arranged with the heat radiation mechanism 23 having the coiled gas passage 24 provided therebetween. Reference numeral 25 is a heat radiation fin provided on the outer periphery of the heat radiation mechanism 23.

Reference numerals 26 are square or round C-rings, respectively. By mounting the square or round C-rings 26, it becomes impossible to disassemble, and accidents due to assembly mistakes can be prevented. That is, after the regulator mechanism 22 is set in the regulator body 1, the square or round C ring 26 is pushed into the regulator body 1 with the collar 27 attached to the collar 27, and the square or round C ring 26 is inserted into the regulator body 1. When it comes to the inner groove 28, it is expanded in diameter and positioned so that it cannot be disassembled. Furthermore, if the heat dissipation mechanism 23 and the regulator mechanism 21 are set and then another square or round C ring 26 is fitted, the whole structure cannot be disassembled.

Therefore, in this case, when the sectional pressure E of the gas passage 3 of the regulator mechanism 21 is smaller than the sum of the spring pressure F of the spring 10 and the sectional pressure G of the small hole 11, the inner cylinder 2 is pushed up and opened. The gas in the heat dissipation mechanism 23 flows to the gas passage 3 side.

Therefore, since the sectional pressure H of the heat dissipation mechanism 23 is lowered (the sectional pressure I of the small hole 11 and the spring pressure J of the spring 10), E <F + G ------------
Smaller than the sum) of the small hole 11 'of the regulator mechanism 22.
The gas flows through the heat dissipation mechanism 23.

H <I + J ------------ Opening and sectional pressure D of the gas passage 3 of the regulator mechanism 21
When becomes the set pressure, the inner cylinder 2 is pushed down and the gas is cut.

A + B <D --------------- When the sectional pressure H of the heat dissipation mechanism 23 also reaches the set pressure, the inner cylinder 2'of the regulator mechanism 22 is pushed down,
Gas is cut.

H> I + J ------------- The coiled gas passage of the heat dissipation mechanism 23 is a circuit only for lowering the gas temperature to room temperature, and the heat dissipation fins 25 are provided around it. Is attached to promote the heat dissipation effect.
