BB gun loading device
A BB gun loading device includes a feeder, a loading unit, a power breaker, and an ejection unit. The loading unit includes a worm, a driven pulley, and a motor. The worm is inserted into the feeder and coupled to the driven pulley which is driven by the motor to rotate. The rotation of the driven pulley links the worm to load BB balls in the feeder for shooting. The power breaker is adapted to cut off power supply. The ejection unit includes a press rod and a touch switch. By pressing the press rod, the touch switch is activated to link the worm to move backward so as to clear the jammed chamber.
1. Field of the Invention
The present invention relates to a BB gun loading device, and more particularly to one applied to a BB gun, with auto loading and being capable of clearing a jammed chamber.
2. Description of the Prior Art
A conventional BB gun uses high pressurized air to shoot BB balls, but in many events the gun fires in empty chamber.
In order to solve the problem, the inventor applied for Taiwanese Publication No. M333550 “An electronic control device to shoot BB balls”, which uses a sensor to increase accuracy of shooting.
The conventional BB gun has a feeder secured on top of the gun to carry BB balls, as shown in
The present invention provides a device to load balls for a BB gun, in particular to a worm which is driven by a motor when the gun is triggered to feed balls. When shooting is stopped, the worm will move backward to activate a power breaker to cut off the power supply. An ejection unit is designed to clear any jammed situation.
According to the present invention, there is provided a BB gun loading device, comprising:
- a feeder having a top, a center, a front end and a rear end, the center having a first chamber, the top having an insertion groove interconnecting with the first chamber, the rear end having a second chamber, the front end having a third chamber;
- a loading unit comprising a worm, a driven pulley, and a motor, the worm being disposed in the first chamber of the feeder and coupled to the driven pulley, the motor driving the driven pulley;
- a power breaker disposed in the second chamber of the feeder, the power breaker comprising a holder and a breaker switch, the holder having a front end and a rear end, the front end of the holder being provided with a sleeve, a push rod, and a first elastic member, the first elastic member being located between the sleeve and the push rod, the push rod holding against the worm of the loading unit, the rear end of the holder being provided with the breaker switch corresponding to the push rod; and
- an ejection unit disposed in the third chamber of the feeder, the ejection unit comprising a press rod, a touch switch, and a second elastic member, the press rod having a first end and a second end, the first end of the press rod corresponding to the worm of the loading unit, the second elastic member being disposed on the first end of the press rod, the touch switch being disposed at the second end of the press rod.
Preferably, the BB gun loading device further comprises a loader, the loader being inserted into the insertion groove of the feeder.
Preferably, the breaker switch is a micro switch, a magnetic induction switch or a light sensor switch.
Preferably, the sleeve is formed with a through hole at a center position thereof for insertion of the push rod.
Preferably, the press rod of the ejection unit activates the touch switch to drive the motor to link the worm to move backward when the press rod is pressed.
Preferably, the touch switch is electrically connected to the motor.
It is the primary object of the present invention to provide a BB gun loading device, which can load with massive balls to save the time of reloading.
It is another object of the present invention to provide a BB gun loading device, which can insert the loader direct to the insertion groove at the top of the feeder to facilitate loading process.
It is still another object of the present invention to provide a BB gun loading device, which has the feeder installed directly on top of the drop hole of the gun to maintain the gun in a constant shooting ready.
It is a further object of the present invention to provide a BB gun loading device, which provides the power breaker to cut off the power supply when the BB balls are fed into and jammed the chamber. The worm is linked to move backward until it reaches the push rod which then will activate the power breaker to cut off the power supply.
It is still a further object of the present invention to provide a BB gun loading device, which uses the push rod to link the worm to clear the jammed chamber.
It is still a further object of the present invention to provide a BB gun loading device, which uses the press rod to activate the touch switch which links the motor to drive the worm to move backward to clear the jammed chamber.
As shown in
The feeder 1 has a top, a center, a front end, and a rear end. The center of the feeder 1 has a first chamber 11. The top of the feeder 1 has an insertion groove 12 interconnecting with the first chamber 11. The rear end of the feeder 1 has a second chamber 13. The front end of the feeder 1 has a third chamber 14. A fixture 15 extends from a lower edge of the front end of the feeder 1. A guiding groove 151 is formed in the fixture 15.
The loading unit 2 comprises a worm 21, a driven pulley 22, and a motor 23. The worm 21 having two ends is disposed in the first chamber 11 and coupled to the driven pulley 22. The motor 23 is used to drive the driven pulley 22 to link the worm 21 to move.
The power breaker 3 corresponding to the loading unit 2 is disposed in the second chamber 13. The power breaker 3 comprises a holder 31. The holder 31 has a front end and a rear end. A sleeve 32 protrudes from the front end of the holder 31. A through hole 33 is formed in the center of the sleeve 32. A push rod 34 is provided at a front end of the sleeve 32 and inserted into the through hole 33. A first elastic member 35 is provided between the sleeve 32 and the push rod 34. The first elastic member 35 urges the push rod 34 to engage with the worm 21 of the loading unit 2. The rear end of the holder 31 is provided with a breaker switch 36 corresponding to the push rod 34. The breaker switch 36 is a micro switch, a magnetic induction switch or a light sensor switch.
The ejection unit 4 corresponding to the worm 21 of the loading unit 2 is disposed in the third chamber 14 of the feeder 1 and comprises a press rod 41. The press rod 41 has a first end and a second end. The first end of the press rod 41 corresponds to the worm 21 of the loading unit 2. A second elastic member 42 is provided on the first end of the press rod 41, urging the worm 21 of the loading unit 2 to clear the jammed chamber by force. The second end of the press rod 41 is provided with a touch switch 43. The touch switch 43 is electrically connected to the motor 23. When the push force is applied, the touch switch 43 will be activated to drive the motor 23 which links the worm 21 to move backward. This can clear the jammed chamber, either.
The loader 5 is to load BB balls 51 and is inserted into the insertion groove 12 on the top of the feeder 1.
To assemble the present invention, as shown in
To operate the present invention, as shown in
When shooting is stopped, as shown in
When reloading the BB balls 51, because all the BB balls 51 in the loader 5 are fired, the BB balls 51 will be released from squeezing. Hence, the worm 21 will be forced by the first elastic member 35 to disengage from the breaker switch 36. The electric power is resumed, and the motor 23 is running again.
When jamming occurred, as shown in
