Description

The double dynamical gear structure of peashooter high rate of fire

Technical field

The utility model relates to the double dynamical gear structure of peashooter high rate of fire and makes field, refers to especially a kind of peashooter gear structure that can effectively avoid repeating to be packed into before percussion bullet.

Background technology

Generally can launch in the peashooter product of plastic material bullet at present, common are two kinds of structures of vapour-pressure type and mechanical type, vapour-pressure type peashooter is with an additional gas cylinder supply peashooter pressure-air, and utilizes pressure that pressure-air produces to promote outwards transmitting of plastic bullets; Mechanical type toy rifle is that the elastic force that produces while upholding with spring by compression promotes a piston and produces pressure-air and promote outwards transmitting of plastic bullets, and therefore the two also have obvious difference due to power resources difference in structure.

In No. ZL200520136485.3 " Double-driving toy gun control gear " utility model patent case of China of this case patent application, this case inventor has researched and developed manual and electrical motor driven has been annexed to the structure in single peashooter, this kind of structure is in the time of practical application, under motoring condition, in the time of power-off, electro-motor can depart from precalculated position because effect of inertia continues to drive compound gear to rotate, or because producing reversion, side protruding pin crash panel machine default on compound gear departs from precalculated position, while causing electro-motor again to activate, cannot effectively engage driving, cause peashooter card bullet occurs or repeat bullet and the situation of two bullets of shot.

For this reason, this case inventor applied for having again No. ZL200820302448.9 " Double-driving toy gun control gear " utility model patent case of another improvement afterwards, and it mainly comprises: a head rod, one first impeller and a transmission group; Described head rod one end is to be articulated with the first impeller, the other end of head rod is connected with a plate machine, aforementioned panels machine can drive head rod horizontal sliding, and via the first impeller interlock one switch, makes the power supply of switch conduction one electro-motor; Described transmission group has a compound gear being connected with electro-motor, is provided with an elastic cantilever and an interlock protruding pin on aforementioned compound gear, and described interlock protruding pin is positioned at the free end of aforementioned elastic cantilever; In the time of practical application, said structure can coordinate the associated mechanisms being made up of a rifle shell, a gunlock sleeve pipe and a piston and implement; Wherein said gunlock sleeve pipe and piston are positioned at rifle shell, and aforementioned gunlock sleeve pipe is provided with a L shaped hook portion being positioned on interlock protruding pin active path, aforementioned piston base is provided with a tooth bar corresponding with compound gear, and piston is to stretch in gunlock sleeve pipe with part at least; In the time that the power supply of aforementioned electro-motor is switched on, can move pivotally via compound gear, to drive piston to form backward compression, and interlock protruding pin drives gunlock sleeve pipe to contract to recurve via L shaped hook portion immediately, makes the bullet in a default magazine be scheduled to treat firing position to falling to gunlock sleeve pipe front; After aforementioned compound gear separates with tooth bar, piston returns back to original position and by the air Fast Compression in gunlock sleeve pipe, can will treat that the bullet on firing position outwards pulls the trigger.

But, said structure is in the time of actual act, because described gunlock sleeve pipe is in the process of recessed retraction bullet, aforementioned piston is also simultaneously in compression process, therefore plastic bullets imports after firing position, can maintain a rapid lapse of time labile state (compressed action of piston causes the shake of gunlock sleeve pipe, rocks), to wait for that piston completes compression process, and then continue firing action; Thus, the bullet in this magazine may continue the filling of falling, and still unavoidable meeting causes the situation repeating into bullet to occur.

Because common toy gun structure is still difficult to solve completely the shortcoming repeating into bullet, inventor is the road for those shortcoming Improvements, finally has generation of the present utility model.
