Referring to these figures, the toy gun according to the present embodiment prevents the head from being shaken by the piston that is rapidly accelerated, mitigates impact applied to the head to improve durability, Thereby providing a feeling of immersion and a feeling of reality.

The toy gun 100 according to the present embodiment, which can provide such effects, includes a main body 110, a gear portion 120, and a launch portion 130.

The main body 110 is formed in a total shape, and may have various shapes such as a handgun, a rifle, and a machine gun.

A trigger 113 for triggering the moat and a motor (not shown) driven by the operation of the trigger 113 are provided in the main body 110, 114 are installed.

The gear portion 120 is a gear driven by the motor 114 and is coupled to the inside of the main body 110, and a support protrusion 125 is formed at an upper rear side thereof.

The gear portion 120 is provided with a first gear 121, a second gear 122, a third gear 123 and a fourth gear 124 interlocked with each other sequentially.

The first gear 121 is gear-coupled to the pinion gear 114a formed at the end of the motor 114 in the form of a ring gear 121a in a bevel gear manner.

The second gear 122 is interlocked with the first gear 121 and interlocked with the second gear 122.

The fourth gear 124 is interlocked with the third gear 123. The cylinder gear 124a and the piston gear 124c are coupled to both sides of the fourth gear 124, respectively.

A first tooth 124b is formed in a part of the outer circumferential surface of the cylinder gear 124a in one direction and arranged at regular intervals.

A second tooth 124d is formed in a part of the outer peripheral surface of the piston gear 124c in one direction, and is disposed at the same interval as the first tooth 124b.

At this time, the second toothed portion 124d is further extended in one direction than the first toothed portion 124b.

For example, it is preferable that ten of the first teeth 124b are formed on the cylinder gear 124a and thirteen teeth 129d are formed on the piston gear 124c.

This is because the piston and the cylinder, which will be described later, are driven in gear engagement with the first and second toothed gears, at which time the gears are released from each other.

Also, the first toothed portion 124b and the second toothed portion 124d are formed in one direction from the same line.

Further, a stopper 126 is provided on one side of the first gear 121.

For example, the stopper 126 prevents the first gear 121 from being reversely rotated in the same manner as a ratchet (not shown) at one side of the first gear 121.

It may also be formed in the form of a one-way clutch.

This is to prevent recoil when the driving of the motor 114 is stopped, or to prevent accidental detonation of the movers due to rotation by the first spring 131b and the second spring 132b to be described later .

The launching part 130 generates air pressure in the main body 110 to emit the mois- tain disposed in the chamber. The launching part 130 includes a cylinder 131 that is moved in the forward and backward direction as the gear part 120 is driven, (132).

The cylinder 131 is disposed on the upper side of the gear unit 120 so as to be movable in the front and rear direction. The head 131d is coupled to the front side and the first guide 131c is coupled to the rear side.

The head 131d transmits the air pressure generated in the cylinder 131 to the chamber and fires the arsenic through the barrel 112. The cylinder 131 and the piston 132 are moved forward The user hits the inside of the main body 110 and receives a physical shock.

As a result, the head 131d can not be held in place due to shaking, and the position at which the air pressure is supplied to the mojit is different.

Therefore, the head 131d is formed to be movable in the cylinder 131 by a predetermined distance so that the head 131d is held in place even when the cylinder 131 is shaken, .

Specifically, an elongated hole 131f is formed on the front side of the cylinder 131, and a moving shaft 131e is formed on both sides of the head 131d to be inserted into the elongated hole 131f so as to be movable forward and backward. do.

A first spring 131b which is contracted as the cylinder 131 is moved rearward is coupled or supported to the rear of the first guide 131c.

A first rak 131a is formed at a position opposite to the first tooth 124b of the cylinder gear 124a and a cutout 131g is formed at the rear of the lower surface of the cylinder 131 .

Here, the first lever 131a and the first toothed wheel 124b are engaged with each other, and the cylinder 131 is moved rearward according to the driving of the cylinder gear 124a, and the first spring 131b is contracted.

At this time, when the portion of the cylinder 131 where the first toothed portion 124b of the cylinder gear 124a ends, that is, the portion where the first toothed portion 124b is not formed, reaches the first recoil 131a , The gear engagement with the cylinder gear 124a is released.

Accordingly, the cylinder 131 is moved forward again by the elastic force of the first spring 131b.

The piston 132 is movably provided in the cylinder 131 in the forward and backward directions and a second spring 132b is provided at the rear of the piston to contract as the piston 132 moves backward.

The rear side of the second spring 132b is supported by a support jaw 125 inserted into the cylinder 131 through the cutout 131g of the cylinder 131. [

At this time, a second guide 132c, to which the second spring 132b is coupled or supported, is formed in front of the support step 125.

A second rak 132a is formed on a rear surface of the piston 132 and protrudes downward through the cutout 131g and extends forward along the lower surface of the cylinder 131 .

Here, the second rak 132a is disposed in parallel with the first rak 131a, and the respective rear ends are located on the same line.

The tips of the first and second leaks 131a and 132a are formed to correspond to the first teeth 124b and the teeth of the second tooth 124d. May be further extended forward than the first leaks 131a.

This is to correspond to the second tooth 124d formed more than the first tooth 124b.

Meanwhile, the cylinder gear 124a and the piston gear 124c move the cylinder 131 and the piston 132 backward as the fourth gear 124 is driven.

Thereafter, the cylinder 131 is moved forward when the gear teeth of the first tooth 124b and the first lock 131a are released. At this time, the piston 132 moves to the second tooth 124d Is fixed by the second lock 132a, and only the cylinder 131 is moved forward.

Accordingly, after the cylinder 131 is first moved forward, the piston 132 is moved forward while being disengaged from the second tooth 124d and the second lever 132a, It will launch a mojitan.

Hereinafter, the operation of the toy gun 100 according to the present embodiment will be described.

When the trigger 113 is pulled in a state in which the mois is arranged in a chambers, the motor 114 is driven to drive the gear 120.

Here, the first gear 121, the second gear 122, the third gear 123, and the fourth gear 124 are sequentially driven by the motor 114 in the gear portion 120.

At this time, since the cylinder gear 124a and the piston gear 124c are formed on both sides of the fourth gear 124, the fourth gear 124 rotates together with the cylinder gear 124a and the piston gear 124c.

The first and second leaks 131a and 132a of the cylinder 131 and the piston 132 are engaged with the first teeth 124b and the second teeth 132a by driving the cylinder gear 124a and the piston gear 124c, And is moved rearward while engaging with the second tooth 124d.

At this time, the first spring 131b and the second spring 132b provided at the rear of the cylinder 131 and the piston 132 are contracted.

Here, the cylinder 131 is moved forward before the piston 132. When the first and second teeth 131a and 124b of the cylinder 131 are in contact with the second and third leaks 132a and 132b, The teeth 124d are first disengaged and moved forward by the elasticity of the first spring 131b.

At this time, the piston 132 is fixed by the second rak 132a and the second tooth 124d.

When the cylinder 131 is moved forward, the piston gear 124c is driven to disengage the second and third teeth 132a and 124d, 2 spring 132b.

Accordingly, the air pressure generated in the cylinder 131 and the piston 132 is transferred to the chamber by the head 131d, and the ammo is fired into the barrel 112.

The head 131d is moved in the forward and backward directions in front of the cylinder 131 so that the head 131d can be moved in the forward and backward directions even if the piston 132 is moved forward, So that it is possible to maintain a fixed position in the elongated hole 131f and to provide a constant air pressure to the razor.

With this configuration, it is possible to reproduce the feeling of immersion and realism because it is possible to direct the same as the actual situation as well as the revolving.

According to the toy gun according to the present invention, since the cylinder is moved forward and backward like the piston, it is possible to produce the same situation as the actual situation at the time of triggering, thereby obtaining the effect of maximizing the immersion feeling and the real feeling.

Further, by moving the head of the cylinder in the forward and backward directions at a predetermined interval, it is possible to prevent damage or breakage caused by the impact of the piston, thereby improving durability.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
