Gun rear structure

The present invention relates to a post-fixing structure of a gun; in particular, a structure that can be self-retained when the projectile in the magazine or the magazine is used up, and can be applied to the field of various pneumatic toy guns.

Since the development of survival games or paintballs, military fans have increasingly demanded toy guns for games. Military collectors especially care about the appearance and operational sense of toy guns. Currently, they are more suitable for appearance and operation. The toy gun is a gas blow back rifle (GBBR); GBBR has a reciprocating motion and a recoil force that can simulate a real gun, so it has the player's demand for the immersive part.

Generally, the conventional GBBR only shoots the BB bomb and can simulate the reciprocating motion and the recoil force of the real gun. Although there is no post-fixing function, there are some problems in the general design, such as the post-fixing action is not true or after Insufficient durability of the fixed parts is easy to malfunction or the production cost of the fixed parts is high, which is inconvenient for the producer and the user.

The custom toy automatic rifle has been continuously improved in order to be true to the real gun action. The applicant of this case has previously proposed a new application for the Republic of China. No. 100213341, "Toy Gun Structure", the new application discloses a shot that can emit an object (such as a BB bomb) when the toy automatic rifle is fired, and produces a recoil force that simulates a real gun, and can simulate a real gun throw. The function of the shell, this technology makes a major breakthrough in the operation fidelity of the toy gun. However, the case does not reveal that the automatic rifle for the shell-throwing toy should achieve a "durable, reliable, low-cost" simulated real gun machine. The post-determination function must be achieved in conjunction with the new post-determination system.

In view of the above-mentioned lack of the fixed structure of the toy gun, the present invention proposes a post-fixing structure of the gun, which aims to increase the durability and reliability of the post-fixing mechanism of the gun, and reduce the production cost of the parts. In order to improve the post-fixing mechanism of the currently available toy pneumatic rifle; this new type of gun rearing mechanism is more suitable for the automatic rifle pneumatic rifle, because the mechanism of the pneumatic rifle is more complicated than the generally non-shell GBBR, can accommodate The space for setting up a fixed mechanism is limited, and it must be matched with a new type of post-determination system.

The fixed part of the new fixed system adopts the steel plate stamping process, and another purpose is to use the calculated and experimental sheet metal width and shape to increase the strength of the impact force of the rear fixed piece by the gun, while using the thin and thin sheet metal. The thickness of the material can be accommodated in the limited space of the gun body, and it is linked with the mechanical parts such as the gun machine, the supporting elastic plate and the post-release button. Since the weight of the whole system is light and the system burden is low, the action is quick and accurate. Effective and durable; the final film of this system is made of sheet metal stamping process, and the production cost is low. And when the part is worn for a long time, it is cheap and simple to replace the sheet metal part.

In order to effectively reach the gun of the toy gun, the present invention proposes a post-fixing structure of the gun. Please refer to Figure 1A first, which is a perspective view of the fixed structure of the new gun.

The post-fixing structure of the new type of gun has a structure including a post-release button 10 and a rear fixed plate 20 fixed on the shell-removing system module 1, wherein the post-release is released The button 10 is further engaged with the gun body 50 through the latch 11 and is coupled with the rear fixed piece 20 of the machine. The upper rear end 201 of the machine rear fixed piece 20 is provided for receiving the external force to make the rear of the machine. The fixed piece 20 produces an elevation angle to top the rifle to form a rifle.

Please continue to refer to Figure 1B, which is a side view of the rear structure of the new type of gun. It can be seen that when the projectile inside the magazine device is used up, the top plate 31 at the rear end of the shell plate 30 is raised. The upper end 201 of the leading edge of the fixed blade 20 of the rear shell system module 1 causes the rear fixed end 20 of the gun to generate an elevation angle centered on the rotating shaft 12, and is used when the fixed rear plate 20 is tilted up. The buckle guide angle 202 is used to hold the gun 40, and the buckle guide angle 202 can be embedded in the front bump 41 of the bolt machine 40. It can be seen from the figure that the front bump 41 is provided with an oblique guide angle. The oblique guiding angle is just engaged with the buckle guiding angle 202, and the automatic setting of the gun can be achieved (no elastic setting), since the buckle guiding angle 202 and the oblique guiding angle of the front projection 41 are geometric complementary angles, When the impact force of the bolt 40 acts on the rear stator, the closer the two will be fastened, the post-timing can be effectively prevented from sliding. In addition, the front bumps 41 on the gun 40 can be lengthened or shortened according to the different positions of different types of gun-type guns, so as to achieve the same post position as the real gun, and increase the degree of immersiveness.

After the completion of the gun 40, if the user wants to release the pressing of the lower release button 10, the L-shaped column 102 can be linked, and the vertical angle between the L-shaped column 102 and the rear fixed plate 20 is designed. The end surface 104 of the L-shaped column 102 can be slid along the edge of the notch 203 provided on the rear plate 20 of the machine to the lower rear platen 20 to release the buckled guide angle 202 of the rear plate 20 of the machine. Top of the gun 40 峙, the state of the gun is released; from the 1C chart, it can be seen that the composition of each component has reached the appearance of the pseudo-firearm, and the structure of the good gun is designed from the limited gun body space. The reference to Fig. 1C can be synchronized, which is a front view of the rear structure of the new gun.

Next, please continue to refer to Figure 2A. After the structure of the new gun is fixed, the release button is disassembled (1). It can be seen from the figure that the release button 10 is further provided with a release button perforation. The 101 and L-shaped columns 102, and more preferably, use a latch 11 to pass through the release button through hole 101 to fix the trailing release button 10 to the through hole 51 of the gun body 50; and the L-shaped column 102 is disposed at the rear release button. The back edge of the 10 is combined with the notch 203 provided on the rear fixed piece 20 of the gun machine to form a linkage. For the above structure, please refer to FIG. 2B, which is the release button (2) after the fixed structure of the new gun.

Please continue to refer to Figure 3A, which is a schematic diagram of the state of the new gun after the fixed structure (1); the embodiment in the figure is the timing of the rear of the gun, the action state of the fixed structure of the gun, 3A is the left side of the structure When the upper end 201 is supported by the external force, the rear fixed piece 20 of the machine can be generated with an elevation angle centered on the rotating shaft 12, and the displacement of the buckle guide angle 202 when the fixed piece 20 is raised by the rear of the machine is used. Hold the gun (not shown), please continue to refer to Figure 3B, which is the state after the fixed structure of the new gun (2); 3B is the right side of the structure, you can see the release button The L-shaped column 102 disposed on the 10 is passed through the notch 203 of the fixed piece 20 of the gun to interlock the release button 10 with the rear plate 20 of the machine; the L-shaped column 102 disposed on the release button 10 is mainly The purpose is to change the angle between the release button and the rear of the gun. Degree of change, because the angle of rotation of the two must be properly matched by changing the length of the arm of the two moments to obtain the correct stroke required for the final action, so the design of the mechanism is indispensable Sex, without this L-shaped design, it will not be able to achieve the correct post-function.

The arc-shaped spherical surface 104 is further designed at the end of the L-shaped column 102 and the notch 203. Therefore, the angle of the lifting of the fixed piece 20 after passing through the gun will cause the circular spherical surface 104 of the L-shaped column 102 to slide along the edge of the notch 203. The micro-lifting is performed. At this time, the release button 10 is tilted by the angle of the pin 11 as an axis; the main purpose of the arc-spherical surface 104 is because the rotation axis 11 of the release button 10 and the camera are determined. The rotation axis 12 of the piece 20 is perpendicular to each other. Therefore, the contact point of the L-shaped column 102 with the notch 203 on the rear plate of the machine will include four directions and angle changes, so one of the contact faces must be a circular arc surface. In order to make the movement smooth and not interfere with each other, the design of this mechanism has its indispensable necessity. Without the design of the circular spherical surface 104, the correct post-function will not be achieved; and the inner edge of the lower end of the release button 10 is provided. The elastic member accommodates the groove 103 for accommodating an elastic member (not shown). For the foregoing structure, please refer to FIG. 3C, which is a schematic diagram (3) of the fixed structure of the new gun, and the 3C diagram is a structure. Positive indication.

Please continue to refer to the 4C figure, which is the diagram of the release state of the fixed structure of the new type of gun (3); the embodiment in the figure is the post-release timing, the action state of the fixed structure of the gun, and the 4C diagram is the front view of the structure. After the gun is to be released, it is only necessary to press the release button 10, and then the release button 10 will be rotated by an angle with the pin 11 as an axis, so that the arc spherical surface 104 on the release button 10 is pressed down. Machine setting The lower edge of the notch 203 on the sheet is connected to the rear fixed plate 10 of the gun to rotate downward by an angle centering on the rotating shaft 12, so that the buckle guiding angle 202 is separated from the oblique guiding angle on the cam 41 of the machine, and the lifting action is completed, and then The elastic member (not shown) accommodated in the elastic member groove 103 at the lower end of the button 10 is used to push the lower end of the rear release button 10 to interlock the L-shaped column 102, so that the rear release button and the rear plate of the machine are fixed. In the case of the top plate 31 at the rear end of the unsupported elastic plate 30, it is ensured that the firearm is always maintained in a non-reset state (this state is the same as that of the real gun). For the above operation, please refer to Figures 4B and 4A simultaneously, which is the new type of machine. The release state of the post-determination structure is shown in (2) and (1).

Next, please refer to FIG. 5A, which is a front view of the release button after the rear structure of the new type of the gun; in FIG. 5A, it can be seen that the L-shaped column 102 disposed after the release button 10 is passed through the machine and is fixed. The notch 203 is used to interlock the rear release button 10 with the rear fixed piece of the gun. The end of the L-shaped column 102 is further designed as an arc spherical surface 104, and the circular spherical surface 104 is used for the L-shaped column 102 to be behind the gun. The edge of the notch 203 of the fixed piece slides, thereby changing the state (angle) of the fixed piece of the machine, and the design of the circular spherical surface 104 can make the angle of the rear fixed piece of the machine change more smoothly (Smooth), and the foregoing structure can be Synchronously refer to Figure 5B, which is a side view of the release button after the rear structure of the new type of gun.

Finally, please refer to FIG. 6A, which is an embodiment (1) of the rear structure of the new type of gun. The rear structure of the machine is constructed on the shell-removing system module 1, and the structure includes a post-release button 10 And the rear fixed plate 20 of the gun is fixed on the shell system 1 , wherein the rear release button 10 is evenly coupled to the gun body 50 through the bolt 11 and is coupled with the rear stator 20 of the gun. The fixed piece 20 is provided with upper The support end 201 can be placed on the top plate of the elastic support plate to cause the rear fixed piece 20 of the machine to generate an elevation angle to top the rifle to form a rifle, and the magazine is disposed in the magazine well 52, and The gun can be placed in the gun base (not shown). It can be seen from Figure 6A that the new structure can completely maintain the appearance and action of the real gun; The fixed mechanism uses the original limited space inside the gun body. It can be seen from Fig. 6B that the components (the rear release button 10 and the rear brake plate 20) are closely attached to the shell system module 1, and the structure It is compact and effective, and does not occupy too much internal space of the gun body.
