Description

Continuous firing mechanism of paintball gun

Technical Field

The invention relates to the technical field of paintball guns, in particular to a continuous firing mechanism of a paintball gun.

Background

At present, the mainstream non-electric control shooting paintball guns in the market only have a semi-automatic shooting function and do not have a full-automatic continuous shooting function. The main reasons for this are that the mainstream paintball guns all adopt a structure of open chamber standby and hopper feed. Firearms in an open-chamber standby state all have high radio frequency, and the paintball gun of the magazine ammunition feed realizes ammunition feed because the ammunition falls only by gravity, the time of the movement of the ammunition to the chamber is long, and the ammunition feed timeliness cannot be matched with the high radio frequency, so that full-automatic emission cannot be realized.

To solve the contradiction between the ammunition supply timeliness and the mismatching of radio frequency, only the radio frequency is greatly reduced or the ammunition supply timeliness is improved. The period of the gravity ammunition feeding of the ammunition bucket is only influenced by the diameter of the ammunition and an ammunition feeding angle, the method for improving the ammunition feeding timeliness of the ammunition bucket in the market at present is to additionally install an electric driving mechanism, however, only the ammunition feeding timeliness is improved without reducing radio frequency, even if reliable ammunition feeding can be realized, a series of problems of low gas utilization rate, low initial speed, poor precision and the like can be caused due to too high radio frequency. In addition, the method for reducing radio frequency in the market mainly adopts an electric control transmitting mechanism, namely high-pressure gas is used as transmitting energy, and electric energy is also used as control energy.

also comprises a time delay body which is matched on the recoil spring guide rod in a sliding way and drives the recoil through a recoil spring of the time delay body sleeved on the recoil spring guide rod, the chain-shot choke is hinged on the choke and is driven to re-advance by a chain-shot choke spring, the lower end of the driving hammer is provided with a strip-shaped groove, the free end of the continuous firing sear is provided with a blocking part and a pressing part which are raised upwards, a yielding space is formed between the blocking part and the pressing part, used for abdicating the lower part of the rear end of the driving hammer, the front end of the blocking part is provided with an inclined plane which is used for matching with the rear end of the driving hammer and pressing down the free end of the continuous firing resistor, the rear end of the blocking part is provided with a limiting surface which is used for matching with the rear wall of the strip-shaped groove, the driving hammer is limited, the rear end of the pressing part is provided with an inclined plane which is used for being matched with the front end of the delay body and pressing the free end of the continuously-triggered sear downwards to remove the limit of the driving hammer;

after the hammer finishes the previous percussion, the hammer moves backwards under the action of air pressure and presses down the free end of the continuous ignition resistance iron to enable a continuous ignition resistance iron spring to be in a compressed state, when the hammer sits in place, the hammer collides with a rear delay body to stop the hammer from sitting backwards, and the hammer spring is in a compressed state;

the hammer spring resets, the hammer moves forwards under the action of the hammer spring, the delay body moves backwards, the repeating sear spring resets, and the free end of the repeating sear moves upwards;

after the hammer moves forwards for a certain distance, the stop face of the blocking part of the continuous firing resistor is matched with the rear wall of the strip-shaped groove to limit the hammer, so that the hammer stops moving forwards, the delay body continues moving backwards, and the re-feeding spring of the delay body is in a compressed state;

the time delay body is reset by the recoil spring, the time delay body moves forwards under the action of the recoil spring of the time delay body, and when the time delay body is in place, the time delay body presses the continuous firing resistor downwards, so that the hammer is released, and the hammer is fired next time under the action of the spring force of the hammer.

Preferably, the repeating resistance iron spring is a torsion spring, one leg of the repeating resistance iron spring is limited on the resistance iron, and the other leg of the repeating resistance iron spring is limited on the lower part of the repeating resistance iron.

Preferably, the spring force of the hammer spring is greater than the spring force of the delay body recoil spring.

Due to the adoption of the technical scheme, the invention has the following beneficial effects:

Detailed Description

Referring to fig. 1-4, a continuous firing mechanism of a paintball gun comprises a blocking iron 1, a hammer 2, wherein the hammer 2 is driven to re-advance by a hammer spring 8, the continuous firing mechanism further comprises a delay body 6, the delay body 6 is in sliding fit with a re-advancing spring guide rod 5 and is driven to re-advance by a delay body re-advancing spring 7 sleeved on the re-advancing spring guide rod 5, the blocking iron 1 is hinged with a continuous firing blocking iron 4, the continuous firing blocking iron 4 is driven to re-advance by a continuous firing blocking iron spring 3, a strip-shaped groove is arranged at the lower end of the hammer 2, a blocking part and a pressing part which protrude upwards are arranged at the free end of the continuous firing blocking iron 4, a yielding space is formed between the blocking part and the pressing part and is used for yielding to the lower part of the rear end of the hammer 2, an inclined plane is arranged at the front end of the blocking part and is used for matching with the rear end of the hammer 2 and pressing the free end of the continuous firing blocking iron 4 downwards, and a limiting surface is arranged at the rear end of the blocking part, the pressing part is used for being matched with the rear wall of the strip-shaped groove and limiting the impact hammer 2, and the rear end of the pressing part is provided with an inclined plane and is used for being matched with the front end of the delay body 6 to press the free end of the continuous ignition resistor 4 downwards so as to relieve the limitation on the impact hammer 2.

The repeating resistance iron spring 3 is a torsion spring, one leg of the repeating resistance iron spring 3 is limited on the resistance iron 1, and the other leg of the repeating resistance iron spring 3 is limited on the lower part of the repeating resistance iron 4. The spring force of the hammer spring 8 is larger than that of the time delay body recoil spring.

As shown in fig. 1, after the hammer completes the previous firing, the hammer moves backward (rightward in the drawing) by the air pressure and collides with the rear delay body when the hammer is seated in position.

As shown in fig. 2, the hammer stops the squat after the collision and moves forward by the hammer spring, while the delay body moves backward.

As shown in fig. 3, the hammer moves forward a short distance and is stopped by the trip resistor, and the delay body continues to move backward.

As shown in fig. 4, the delay body moves forward under the action of the recoil spring after moving backward to the proper position, and when the delay body returns to the proper position, the continuous firing resistor is pressed down by the delay body, so that the hammer is released, and the hammer can perform the next firing under the action of the spring force of the hammer.

The four steps demonstrate the process of realizing the continuous hair by the continuous hair mechanism. Because the hammer is under the action of the repeating sear and the delay body, the hammer can be hung by the repeating sear to stop moving for a period of time, the spring force of the hammer is much larger than the spring force of the recoil spring, and the movement stroke of the delay body is longer, so that the shooting cycle time is greatly prolonged, and the effect of prolonging the cycle time and reducing the radio frequency is realized.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
