[0001] The utility model relates to the field of toy gun, especially short cylinder reduction air gun. BACKGROUND

[0002] In the field of entertainment, training and simulated shooting, there is a continuous demand for toy guns or training equipment that can simulate the shooting feel of real firearms. Traditional toy guns often use simple mechanical structures or spring power to achieve shooting function, and their shooting process is single, lacking the ability of continuous shooting, and the shooting feel is far from real firearms. With the progress of technology and changes in market demand, people began to pursue more realistic and stronger shooting experience.

[0003] However, the existing simulated shooting equipment still has deficiencies in continuous shooting mechanism, shooting stability and operation feel. For example, although some simulated firearms can achieve continuous shooting, the recoil force and feedback during shooting are not realistic enough. SUMMARY

[0004] The utility model aims at providing a short cylinder reduction air gun to solve the technical problem that although the traditional simulated firearm can achieve continuous shooting, the shooting feel is not realistic enough.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of providing a short cylinder reduction air gun, which comprises:

[0006] A shell is provided with a barrel inside, and an excitation chamber is arranged inside the shell, which is communicated with the barrel;

[0007] A short cylinder is slidingly arranged in the excitation chamber;

[0008] A first spring is connected to one end of the short cylinder, and the other end of the first spring is connected to the shell;

[0009] An airplane is built in the short cylinder, and a gas pressure cavity is arranged inside the airplane, and a gas pressure cavity outlet is arranged at one end of the airplane close to the barrel, and an air inlet is arranged at the bottom of the airplane;

[0010] A dart is slidingly arranged in the gas pressure cavity of the airplane;

[0011] A magazine is installed on the shell, and an automatic feeding mechanism and a gas valve are arranged inside the magazine, and the outlet of the gas valve is communicated with the air inlet of the airplane;

[0012] A hammer is hinged to the shell, and a torsional spring is arranged on the hammer;

[0013] a striker slidingly arranged on the housing, one end of the striker being connected with the gas valve, the other end of the striker abutting against the hammer;

[0014] a trigger hingedly arranged on the housing, a top of the trigger being provided with a bayonet, the bayonet being in clamping engagement with the hammer, a second spring being arranged between the trigger and the housing.

[0015] In one embodiment, a connecting rod is further arranged, one end of the connecting rod being hingedly arranged on the housing, a third spring being arranged between a bottom of the one end of the connecting rod and the housing, the other end of the connecting rod being in engagement with the clamping groove on the hammer, a top of the connecting rod being located on the sliding track of the short cylinder.

[0016] In one embodiment, a slide rod is further arranged in the housing, the short cylinder and the first spring being sleeved on the slide rod.

[0017] In one embodiment, the dart comprises an air inlet portion at a front end and a sealing piston at a rear end, the air inlet portion being arranged at an air pressure cavity outlet of the airplane, an air inlet channel being arranged in the air inlet portion, one end of the air inlet channel being in communication with an air inlet of the airplane, the other end of the air inlet channel being in communication with a root of the barrel, the sealing piston being in sliding engagement in the air pressure cavity.

[0019] The one or more technical solutions in the embodiments of the utility model have at least the following technical effects or advantages:

[0020] The short cylinder provided by the utility model realizes automatic loading and continuous shooting of BB bullets through cooperation of the automatic bullet feeding mechanism in the magazine, the gas valve and the airplane. After the trigger is pulled, the hammer pushes the striker to open the gas valve, high-pressure gas enters the air pressure cavity of the airplane, the gas is output from the air pressure cavity outlet of the airplane after passing through the dart and enters the barrel, so that the BB bullet in the barrel flies out at high speed under the action of air pressure, and the shooting function is realized. Meanwhile, the high-pressure gas pushes the dart to close the air pressure cavity and drives the short cylinder to slide backward, and the hammer is pressed downward to the standby shooting state. After the trigger is reset, the airplane and the short cylinder slide forward under the elastic force of the first spring, the airplane pushes the BB bullet pushed out of the magazine to the shooting position, and continuous shooting is realized.

[0021] The utility model simulates the shooting, recoil and reset processes of a real gun, and provides a more realistic shooting feeling. The trigger feeling when the trigger is pulled, the force feedback when the hammer rotates and the sliding of the short cylinder and the airplane under the action of the recoil force all make the shooting process closer to the real gun.

[0033] Please refer to Figures 1 to 4 The embodiment of the application provides a short cylinder restoring air gun, which comprises a shell, a short cylinder, a first spring, an airplane, a dart, a magazine, a hammer, a firing pin and a trigger. The shell is provided with a barrel, and an exciting chamber is arranged in the shell. The exciting chamber is communicated with the barrel. The short cylinder is slidably arranged in the exciting chamber. One end of the first spring is connected with the short cylinder, and the other end of the first spring is connected with the shell. The airplane is arranged in the short cylinder. The airplane is provided with a gas pressure cavity. The gas pressure cavity is arranged at one end of the airplane close to the barrel. The airplane is provided with an air inlet at the bottom. The dart is slidably arranged in the gas pressure cavity of the airplane. The magazine is arranged on the shell. The magazine is provided with an automatic feeding mechanism and a gas valve. The outlet of the gas valve is communicated with the air inlet of the airplane. The hammer is hingedly connected with the shell. The hammer is provided with a torsional spring. The firing pin is slidably arranged on the shell. One end of the firing pin is connected with the gas valve, and the other end of the firing pin abuts against the hammer. The trigger is hingedly connected with the shell. The top of the trigger is provided with a bayonet. The bayonet is tightly matched with the hammer. The second spring is arranged between the trigger and the shell.

[0034] The specific principle is as follows: the magazine loads the BB bullets in the barrel (the root of the barrel), when the trigger is pulled (such as Figure 2The hammer is rotated upward under the elastic force of the torsion spring and pushes the firing pin, so that the firing pin pushes open the gas valve (the gas valve is connected to a gas supply pipe, the gas supply pipe contains high-pressure gas, and the other end of the gas supply pipe is connected to a gas pump or other gas source), so that the gas is output from the gas valve and enters the aircraft pressure cavity from the air inlet at the bottom of the aircraft. Part of the gas is output from the air pressure cavity outlet of the aircraft after the dart and enters the barrel, so that the BB bullet in the barrel is high-speed ejected under the action of air pressure, realizing the shooting function. At the same time, part of the gas entering from the air inlet at the bottom of the aircraft enters the air pressure cavity, causing the pressure in the air pressure cavity to rise, and then the dart slides towards the air pressure cavity outlet until the air pressure cavity is closed. The closed aircraft drives the short cylinder to slide backward under the backward force of the air pressure, in this process, the first elastic member is compressed, and the short cylinder slides backward and presses down the hammer, so that the hammer rotates downward to the standby firing state (as shown in Figure 3 At the same time, the hammer is reset under the elastic force of the second spring and clamps the hammer, so that the hammer remains in the standby firing state. Due to the downward rotation, the original pushing force acting on the firing pin is removed, so that the firing pin releases the gas valve, the gas valve is closed, the air pressure no longer enters the barrel, and the dart no longer closes the air pressure cavity, so that the aircraft and the short cylinder slide forward to the initial position under the elastic force of the first elastic member, and the BB bullet pushed out by the automatic feeding structure in the magazine is pushed forward to the shooting position (the root of the barrel) when the aircraft slides forward, as shown in Figure 1 At this time, only the trigger needs to be pulled again to shoot the BB bullet again. The purpose of the utility model is to simulate the continuous shooting of a real gun through various firing mechanisms, so as to be closer to the real shooting feel of a gun.

[0035] In one embodiment, a connecting rod is further included, the connecting rod is hinged to the shell, a third spring is arranged between the bottom of one end of the connecting rod and the shell, the other end of the connecting rod cooperates with the clamping groove on the hammer, and the top of the connecting rod is located on the sliding track of the short cylinder. When the short cylinder retreats and presses down the hammer, the connecting rod rotates clockwise under the action of the third elastic member, so that the right end of the connecting rod is clamped into the clamping groove of the hammer (as shown in Figure 3 The hammer is locked in the pressed-down state, so that the trigger below has enough time to reset to clamp the hammer. When the first spring pushes the short cylinder to advance and reset, the bottom of the short cylinder will press down the left side of the connecting rod, so that the connecting rod rotates counterclockwise, and then the connecting rod is separated from the clamping groove of the hammer, so that the connecting rod does not limit the movement of the hammer, so as to control the hammer through the trigger. By arranging the connecting rod, the trigger has enough time to reset and clamp the hammer, and the stability of the continuous shooting structure is improved.

[0036] In one embodiment, a slide rod is further included, the slide rod is arranged in the shell, and the short cylinder top and the first spring are sleeved on the slide rod. The slide rod can guide the sliding movement of the short cylinder and the extension and contraction movement of the first spring.

[0037] As Figure 4 shown, in one embodiment, the dart includes a front end air inlet part and a rear end sealing piston, the air inlet part is arranged at the air pressure cavity outlet of the aircraft, the air inlet part is provided with an air inlet channel, one end of the air inlet channel is communicated with the air inlet of the aircraft, the other end of the air inlet channel is communicated with the barrel root; the sealing piston is slidingly fitted in the air pressure cavity. After the high-pressure gas enters the air pressure cavity from the air inlet of the aircraft, part of the gas flows to the barrel through the air inlet channel of the air inlet part to push the BB bullet out, and part of the gas enters the air pressure cavity, so that the pressure in the air pressure cavity is increased, and then the sealing piston is pushed to slide to the left until the air pressure cavity outlet of the aircraft is closed, causing the high-pressure gas to push the aircraft and the short cylinder to retreat.

[0038] In one embodiment, the bottom of the shell is provided with a handle, and the surface of the handle is provided with anti-skid lines. The anti-skid lines can improve the hand feeling when the user holds the gun, improve the comfort, and avoid slipping.

[0039] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
