A movable elastic shell ejection mechanism

Abstract

The present invention discloses a movable elastic ejection mechanism, which realizes elastic ejection and can automatically give way and return to its original position when the ejector interferes with the feeding of the cartridge. In the free state, under the action of the ejector spring, the front end surface of the ejector presses against the plug, and the ejector is in a state ready for ejection. When a cartridge case contacts the ejection portion of the ejector and drives the ejector backward, the cartridge case drives the ejector backward and compresses the ejector spring. When the cartridge case reaches the ejection position, the ejector spring releases energy, causing the ejector to move forward, completing the ejection. Then, the ejector automatically returns to the state ready for ejection under the action of the ejector spring. In the feeding state, when a cartridge case is caught in the ejection portion, the cartridge case presses the rear end inclined surface of the ejection portion, and the front end of the ejector moves upward under the action of the cartridge, giving way to the cartridge. The upper front end of the ejector enters the upper notch. After the cartridge passes through, the ejector automatically returns to its original position under the action of the ejector spring.

Description

Technical Field

[0001] The present invention relates to the technical field of firearms, and in particular to a movable elastic shell ejection mechanism. Background Art

[0002] Existing ejection mechanisms primarily include rigid ejection and elastic ejection. Rigid ejection is typically used in firearms with high-speed automatic mechanisms, while elastic ejection is typically used in firearms with weaker automatic mechanisms or manual ejection. The ejector is located inside the receiver and can only move longitudinally (as shown in utility model patent application number 200820099843.1). During feeding, if the cartridge slightly deviates from the standard position, the ejector may interfere with feeding, causing the firearm to malfunction. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a movable elastic shell ejection mechanism to realize the elastic shell ejection and the function of automatically giving way and returning to a position when the shell ejector interferes with the feeding of the ammunition.

[0004] The object of the present invention is achieved like this:

[0005] The cam is secured to the rear of the rifle and has a spring loaded interior surface for receiving the shell, the cam being secured to the rear of the rifle and having a spring loaded interior surface for receiving the shell.

[0006] In the free state, under the action of the ejector spring, the front end of the ejector presses against the plug, forming a downward force component, which is used to make the ejector parallel to the chute, and the ejector is in the state of waiting to eject the shell;

[0007] When the cartridge case contacts the ejection portion of the ejector and drives the ejector backward, the cartridge case drives the ejector backward and compresses the ejector spring. When the cartridge case reaches the ejection position, the ejector spring releases energy and the ejector moves forward, completing the ejection. Then, the ejector automatically returns to the ejection ready state under the action of the ejector spring.

[0008] In the feeding state, when the bullet hooks the ejection part, the bullet presses the inclined surface at the rear end of the ejection part, and the front end of the ejector moves upward under the force of the bullet to make way for the bullet. The upper front end of the ejector enters the upper notch. When the bullet passes through, the ejector automatically returns to its position under the action of the ejector spring.

[0009] Preferably, the width of the lower notch is smaller than the width of the ejector and larger than the width of the ejector, so that the ejector is positioned in the chute and the ejector can be extended.

[0010] Preferably, a stop is formed between the front end of the ejection portion and the ejector, and the stop is used to cooperate with a corresponding plug to limit the upper limit position of the ejection portion.

[0011] Preferably, a clearance notch is provided at the upper front end of the shell ejector, and the clearance notch at the upper front end of the shell ejector is used to prevent an upper notch from emerging from the upper front end of the shell ejector.

[0012] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0013] When ejecting a shell, the shell contacts the ejector and drives the ejector backward. The ejector spring stores energy. When it moves to the ejection position, the ejector spring releases energy and pops out, ejecting the shell and driving the ejector back. When feeding, if the shell contacts the inclined surface at the rear end of the ejector, the ejector will move sideways to make way and prevent the ejector from interfering with feeding. After the shell passes, it will automatically return to its position under the action of the ejector spring.

[0014] The present invention is composed of separate parts, which are relatively simple to assemble and maintain, and provides users with a good shooting experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-Figure 5 A flexible, resilient ejection mechanism that allows for flexible ejection and automatically returns to its original position if the ejector lever interferes with ammunition feeding. The mechanism is constructed as a single component, simplifying assembly and maintenance, providing a superior shooting experience.

[0023] The present invention mainly consists of five parts: 1. a shell ejector seat; 2. a shell ejector; 3. a shell ejector head; 4. a shell ejector spring; and 5. a plug.

[0024] In the free state, the ejector spring pushes the ejector rear end face, and the ejector front end inclined surface presses against the plug. Figure 2 As shown, the ejector spring is in the ejection position. The inclined surface forces the front end of the ejector to move downward. The upper rear end of the ejector cooperates with the upper wall of the chute to limit its movement, preventing it from moving downward beyond a position parallel to the chute. The lower front end of the ejector is provided with an ejection unit. Under normal conditions, friction is generated when the front end of the ejection unit contacts the bullet.

[0025] When the cartridge case contacts the ejector and drives the ejector backward, the ejector maintains its vertical position unchanged due to the friction between the cartridge case and the ejector. The cartridge case drives the ejector backward, and at the same time the ejector spring is compressed to store energy.

[0026] When the cartridge case reaches the ejection position, the ejector spring releases energy, the ejector moves forward, and the ejected cartridge case flips forward out of the receiver.

[0027] After the shell is ejected, the ejector spring automatically returns to the ejection state.

[0028] When feeding, when the bullet hits the ejector, the bullet presses the rear end of the ejector, and the ejector moves to the outside of the receiver under the force of the bullet and moves back a certain distance to make way for the bullet. Figure 5 shown.

[0029] When the bullet passes through, it automatically returns to its original position under the action of the ejector spring.

[0030] Make the push rod connecting sleeve hook enter the annular groove in the ring. After releasing the trigger, the trigger automatically returns to its position, connecting the handguard and the push rod connecting sleeve together. At this time, the gun is in pump-action mode.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
