Definitions
- the description below relates to a cylinder assembly for use in an automatic loading device equipped with a gas toy gun.
- the engine's performance is comparable.
- the autoloaders of companies that inherited the design of MGC generally use cylinder diameters of 14-15mm and cylinder lengths in the early to late 20mm range.
- Western Arms has a special long cylinder length of mid 30mm, but this was possible by reducing the diameter of the cylinder to less than 14mm. All of these existing products have only one cylinder built-in, which reduces the cylinder length or diameter due to the shape of the model gun.
- Korean Patent Laid-Open Publication No. 2003-0070418 discloses a baboon bullet supply device for a toy gun
- Korean Patent Publication No. 2010-0132379 discloses a triggering structure of a toy gun.
- the performance of the automatic loading device is proportional to the volume of the cylinder.
- the maximum suppression of recoil is a virtue, but in gas-operated toy guns, the stronger the recoil, the more the product is recognized as a high-performance product.
- the maximum slide distance of the pistol is about 44 to 50 mm, and in the case of a rifle of the rifle, it is 80 mm or more.
- the existing gas-operated toy guns have a cylinder length of 20-25 mm in the pistol type and 50-62 mm in the rifle type, so that the ball cage wins the elasticity of the left spring by the inertia force alone. Should.
- gas-operated toy guns are often equipped with a stop mechanism that retracts and locks the ball stack when all the bullets inside the magazine are fired.
- the existing autoloader stops the ball stack in a low temperature, continuous trigger situation. If you can not move to the position where the tooth is caught will continue.
- the process of reloading the nozzle and loading the charcoal may be interrupted.
- the two cylinders are telescopically arranged to greatly extend the length of the cylinder.
- extension cylinder which is conveyed in the longitudinal direction of a cylinder inside a cylinder main body, and inside this extension cylinder is a nozzle part which is responsible for gas input and a bullet reload.
- the cylinder valve inside the nozzle unit When compressed gas is input to the automatic loading mechanism, the cylinder valve inside the nozzle unit operates to discharge a small amount of gas forward to fire a bullet and close the front outlet.
- the compressed gas induced backward by the front outlet closing is first introduced into the cylinder body.
- the gas flowing into the cylinder body is pushed together with the extension cylinder and the nozzle to start the primary transfer of the bunch of nuts.
- the extension cylinder is transported to a limit point at which the seal between the extension cylinder and the cylinder body is maintained, and then temporarily stopped while maintaining the gas pressure seal by the transport distance limiter.
- gas is introduced into the extension cylinder, and the extension cylinder pushes the nozzle forward, and secondly transports the cylinder body.
- the nozzle unit supporting member connected to the protrusion of the extension cylinder and supporting the nozzle unit supports the nozzle unit.
- the nozzle portion extends to the outside, and there is a possibility that the nozzle portion is shifted by the lever principle due to the elastic force acting on the nozzle portion.
- the nozzle extending to the outside may be displaced by the elasticity in which the magazine spring pushes the bullet.
- the force of the spring pushing the bullet such as the bullet from the bottom is applied to the nozzle part, which may cause the nozzle part to be displaced due to such elastic force. .
- the nozzle part and the extension cylinder are accommodated in the cylinder body by the elastic body connecting the nozzle part and the cylinder body, and the cylinder valve is also returned to the front opening state again by the elastic body which returns the cylinder valve to its original position. Finish the bullet.
- the cylinder body then advances by the elastic body to load the next bullet into the chamber.
- the cylinder assembly is formed in the inner space, an extension cylinder accommodated in the cylinder body, movable in the longitudinal direction of the cylinder body in the interior of the cylinder body, at least a part of the extension cylinder And a nozzle unit accommodated and movable in the longitudinal direction of the cylinder body, both sides of which are open and in which a gas inlet is formed, connected to the extension cylinder, a nozzle unit support member supporting the nozzle unit, and a cylinder valve capable of opening and closing the nozzle.
- the inner space may be primarily expanded according to the movement of the extension cylinder, and the inner space may be additionally expanded according to the movement of the nozzle.
- the nozzle support member is inserted and coupled with the protrusion formed in the body portion and the extension cylinder surrounding the outside of the nozzle portion, it may include a locking portion extending along the body portion.
- a protrusion is formed outside the extension cylinder, a first guide groove is formed in the cylinder body in the longitudinal direction of the cylinder body, the protrusion is accommodated in the first guide groove is the first By moving in the guide groove the movement of the extension cylinder can be restricted.
- one side may further include a first elastic body connected to the cylinder body and the other side is connected to the nozzle to provide a restoring force to the nozzle.
- the other side of the first elastic body may be fixed to the nozzle by a pin passing through the nozzle, one side is connected to the nozzle and the other side is connected to the cylinder valve to provide a restoring force to the cylinder valve. It may further include a second elastic body that can be.
- a communication hole for injecting the gas injected from the gas inlet to the cylinder body may be formed.
- the primary feed is driven by extension cylinders with strong traction but with low maximum feed rate, and the secondary feed is accelerated by a bunch of bolts by the nozzle that has relatively low traction but high operating speed. You get the same effect as shifting and accelerating.

- One side of the second elastic body 141 may be connected to the nozzle unit 130, and the other side thereof may be connected to the cylinder valve 140.
- the cylinder valve 140 may be moved to the front of the nozzle unit 130 by the injected gas to close the nozzle unit 130. Thereafter, when the supply of the gas is stopped, the cylinder valve 140 may be separated from the nozzle unit 130 by the restoring force of the second elastic body 141 to open the nozzle unit 130 to the outside air.
- the nozzle support member 200 may be regarded as a hollow pipe formed in a form surrounding the outside of the nozzle unit 130 to support the nozzle unit 130.
- the rear end of the body portion 201, the engaging portion 202 formed in the 'c' shape to have an inner receiving groove corresponding to the protrusion 122 so as to be coupled to the protrusion 122 protruding outside the extension cylinder 120 , 203 is formed along the outer circumferential surface of the body portion 201.
- the protrusion 122 formed on the outer side of the extension cylinder 120 may be accommodated in the first guide groove 112 formed in the cylinder body 110 to guide the movement of the extension cylinder 120.
- the protrusion 122 may limit the moving range of the extension cylinder 120 so that the protrusion 122 does not go out of the range in which the sealing of the inner space 111 is maintained.
- the nozzle unit support member 200 coupled with the protrusion 122 may support the nozzle unit 130 extending in two steps to prevent the nozzle unit 130 from being displaced by the elastic force. Let's explain.
- a communication hole 121 may be formed in communication with the nozzle unit 130 and the cylinder body 110 to inject the gas injected from the gas injection hole 134 into the cylinder body 110. have.
