ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a toy gun, and more particularly to a toy gun that is operated smoothly and stably.
2. Description of the Related Art
A conventional toy gun comprises a gun body, a magazine mounted in the gun body and having a first side formed with a bullet chamber for mounting a compression spring, a push block and a plurality of BB bullets and a second side formed with a gas chamber containing high pressure gas, and a gas control device mounted on the gun body for guiding the high pressure gas from the gas chamber of the magazine to flow toward the barrel of the gun body, so that the uppermost BB bullet is pressed by the high pressure gas and is ejected outward from the barrel.
However, the gas control device cannot control the gas flow of the gas chamber of the magazine easily and exactly, so that the toy gun is not operated smoothly and stably, thereby causing inconvenience to the user.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a toy gun, wherein the gas control device can control operation of the gas valve of the gas chamber of the magazine exactly, so that the toy gun is operated smoothly and stably.
Another objective of the present invention is to provide a toy gun, wherein the striking portion of the hammer strikes the valve block of the gas guide valve of the slide to actuate the gas guide valve of the slide to guide the high pressure gas from the gas chamber of the magazine to flow toward the barrel of the slide, so that the uppermost BB bullet is pressed by the high pressure gas and is ejected outward from the barrel of the slide rapidly and actually.
In accordance with the present invention, there is provided a toy gun, comprising a gun body, a support seat, a magazine, and a gas control device, wherein:
the gun body has a vertical section formed with a magazine chamber, a horizontal section formed with a receiving channel and a mediate section provided with a trigger chamber for mounting a trigger;
the support seat is mounted in the receiving channel of the gun body, the support seat has a first end formed with a spring chamber and a second end formed with a receiving recess, the receiving recess of the support seat has a first end having a side formed with an opening having a bottom formed with a first mounting hole for mounting a first compression spring and a first push rod, the receiving recess of the support seat has a second end having a side formed with a second mounting hole for mounting a second compression spring and a second push rod;
the magazine is mounted in the magazine chamber of the gun body;
the gas control device is mounted in the receiving recess of the support seat and includes a link, a press plate, a baffle, a first clamping block, a driven block, a second clamping block, a limit plate, a hammer, a first shaft, and a second shaft, wherein:
the link has a first end pivotally connected with an end of the trigger and a second end mounted in the opening of the support seat, the second end of the link has a first side rested on the first push rod of the support seat and a second side formed with an oblique pressing edge;
the press plate has a first end formed with a pressed block formed with a pivot hole and a second end formed with a mounting hole, the press plate has a side formed with an oblique pressing edge urged on the oblique pressing edge of the link;
the baffle has a first end formed with a pivot hole and a second end formed with a mounting hole, the baffle has a side formed with passage hole;
the first clamping block has a first section formed with a pivot hole and a second section formed with protruding stub;
the driven block has a first end formed with an elongated slot and a second end formed with a pivot hole for passage of a pivot shaft which is extended through a torsion spring, an end of an action block and an end of a lever;
the second clamping block has a first end formed with a pivot hole and a second end formed with a shaft hole;
the limit plate has a first end formed with a cutout for insertion of the pivot shaft of the driven block, a mediate portion formed with a pivot hole, and a second end formed with a pressing portion urged on the second push rod of the support seat, the second end of the limit plate is provided with a pressed block;
the hammer has a first end formed with a pivot hole and a second end formed with a striking portion;
the first shaft is in turn extended through the pivot hole of the press plate, the pivot hole of the baffle, the pivot hole of the first clamping block, the elongated slot of the driven block, the pivot hole of the second clamping block and the pivot hole of the limit plate; and
the second shaft is in turn extended through the pivot hole of the hammer, the mounting hole of the press plate and the mounting hole of the baffle.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
