Structure of grenade for toy gun
A grenade for toy gun generally includes a bullet compartment having multiple circumferentially arranged accommodation cylinders to receive BB bullets or paintballs therein, a storage chamber forming circumferential raised walls, and an actuation rod assembly that is hollow and has a front end forming an air inlet opening in which a check valve is mounted and a rear end forming an air output opening and circumferential gasket rings. The gasket rings are respectively set in engagement with the raised wall to hermetically seal the storage chamber. Compressed air is fed through the air inlet opening and is discharged through the air output opening to accumulate in the storage chamber. In percussion, the actuation rod assembly is caused to move forward to disengage the gasket ring from the raised wall so as to release the compressed air to instantaneously eject the BB bullets or paintballs received in the bullet compartment.
1. A grenade for a toy gun, comprising:
a front cap;
a bullet compartment, which comprises a centrally-formed through bore, which has a circumference around which a plurality of circumferentially arranged accommodation cylinders is arranged to allow each of the accommodation cylinders to receive, via a front opening thereof, and load BB bullets or paintballs therein;
a storage chamber, which is in communication with the bullet compartment and is delimited by a first raised wall and a second raised wall respectively at front end and rear end thereof;
an actuation rod assembly, which is hollow and is received in the central through bore of the bullet compartment and comprises an air inlet tube arranged at a front side thereof, the air inlet tube having a front end forming an air inlet opening and a rear end to which a first disk and a second disk are mounted, an air output opening being formed between the first disk and the second disk, the first disk and the second disk each having a circumference around which a gasket ring is mounted to set the gasket rings in engagement with the first raised wall and the second raised wall of the storage chamber so as to hermetically seal the storage chamber, whereby compressed air is allowed to feed through the air inlet opening of the air inlet tube and the compressed air is discharged through the air output opening to accumulate in the storage chamber and whereby in percussion, a trigger of a toy grenade launcher is structured to push the actuation rod assembly forward to disengage the first disk from the first raised wall of the storage chamber so as to release the compressed air in the storage chamber to instantaneously eject the BB bullets or paintballs received in the bullet compartment.
2. The grenade according to claim 1 , wherein the storage chamber has a rear end forming an opening, the actuation rod assembly having a rear end forming a projection that is receivable in the opening of the storage chamber for positioning purposes.
3. The grenade according to claim 2 , wherein pressure relief apertures are formed on sides of the opening.
4. The grenade according to claim 1 , wherein each of the accommodation cylinders of the bullet compartment has an inner side portion which is provided with a flexible rubber ring, whereby the BB bullets or paintballs are forcibly movable through the flexible rubber ring to be positioned into each of the accommodation cylinders, the flexible rubber rings blocking and preventing the BB bullets or paintballs from dropping off.
5. The grenade according to claim 1 , wherein the air inlet opening formed in the front end of the air inlet tube of the actuation rod assembly is provided with a check valve mounted therein.
