Steady flow structure of pneumatic power gun

This creation relates to a local structure of a pneumatic power gun; in particular, it is a revealer of an innovative structure of a steady flow structure of a pneumatic power gun.

The pneumatic power gun referred to in this creation is a toy gun product including an air gun, a gas gun, and the like, which is driven by a gas pressure as a bullet.

In the design of the conventional pneumatic power gun, the air pressure introduced into the gun body when the trigger is buckled is usually guided to the barrel through a gas valve to push the bullet to fire. However, due to the design of the valve type, it is still lacking. An ideal and perfect flow guiding mechanism, so that the air pressure introduced into the gun body is in a state of turbulent or swirling airflow when the bullet is fired. (Note: a coil spring is usually installed at the front of the valve, which leads to The air pressure is in a spiral state. As a result, the ball-shaped bullet is affected by the uneven deflection of the ball-shaped bullet and affects the straightness of the ballistic stroke, which affects the quality of the pneumatic gun.

Therefore, in view of the problems existing in the flow guiding structure of the above-mentioned conventional pneumatic power guns, how to develop an innovative structure that can be more ideal and practical, and it is necessary for the relevant industries to think about the goals and directions of breakthroughs; Therefore, the creator has been engaged in the manufacturing development and design experience of related products for many years.

The technical feature of the present invention is mainly that the steady flow structure comprises the following structure: a guide tube is installed in the intake guide cylinder in a forward and backward sliding state, and the guide tube comprises a barrel body and is formed in the tube. a guiding channel in the body, and the barrel body has a front end opening and a rear end wall, wherein the front end opening is oriented toward the barrel, and the rear end wall is sealed at the rear end of the guiding channel, and the barrel is adjacent to the rear end wall a radial through hole is provided for correspondingly connecting the air pressure introduction hole of the air inlet guide tube; a steady flow end is set at a rear end wall of the guide tube body by a rod column body, and the flow is stabilized The tip includes a plurality of splitter sheets in a radially arranged configuration, and each of the splitter sheets is formed with a relatively separated split air guide passage; a tapered guide portion is disposed at the rear end of the rod cylinder adjacent to the guide tube barrel One end of the wall, the tapered guiding portion is tapered from the rod cylinder toward the rear end wall; and a distance between one end of the steady-flow end connecting rod cylinder and the front end of the guiding cylinder barrel .

The main effects and advantages of the creation, through the shape of the flow tube and the steady flow end, enable the air pressure to uniformly and uniformly push the bullet after passing through the steady flow end, thereby greatly increasing the pressure and power gun shooting out of the ballistics. Practical and progressive straightness.

Please refer to Figures 1, 2, 3 and 4 for a preferred embodiment of the steady flow structure of the present pneumatic gun. However, these embodiments are for illustrative purposes only and are not subject to this structure in patent applications. The steady flow structure A is used for the rear position of the bullet 11 ready for firing in a barrel 10 (only shown in FIG. 3) provided in a pneumatic power gun (not shown). And located at a front end of a gas pressure introduction hole 21 provided in an intake guide cylinder 20.

The steady flow structure A includes a steam guide 30 that is mounted in the intake and guide cylinder 20 in an advanceable and retractable state. The guide tube 30 includes a barrel 31 and is formed on the barrel. a guide channel 32 in the 31, and the barrel 31 has a front end opening 33 and a rear end wall 34, wherein the front end opening 33 faces the barrel 10, and the rear end wall 34 is sealed to the guide a rear end of the flow passage 32, and a radial through hole 35 is provided in the tubular body 31 adjacent to the rear end wall 34 for correspondingly connecting the air pressure introduction hole 21 provided in the air intake guide cylinder 20; a steady flow end 40, the rear end wall 34 of the tubular body 31 of the draft tube 30 is set by a rod cylinder 41. The steady flow end 40 includes a plurality of split pieces 42 in a radially arranged configuration (in this case, a three-piece type), a split-dividing air guiding passage 43 is formed between each of the splitting pieces 42; a tapered guiding portion 50 is disposed on the rear end of the tubular body 41 adjacent to the tubular body 31 of the guiding cylinder 30 One end of the wall 34, the tapered guiding portion 50 is tapered by the rod cylinder 41 toward the rear end wall 34; and wherein the stabilizing end 40 connects one end of the rod cylinder 41 with the The front end of the guide barrel 30 The openings 33 have a separation distance W (as shown in Fig. 3).

As shown in FIG. 5, in the present embodiment, the rear end wall 34 of the tubular body 31 of the guide tube 30 is provided with a screw hole 36, and a stud 44 is disposed at one end of the rod cylinder 41. The stud 44 root sleeve has an elastic ring 45, and the rear end wall 34 is provided with a recess 37 for inserting one end of the tapered guiding portion 50. The embodiment disclosed in this example is mainly capable of utilizing the The rod cylinder 41 has a function of being able to adjust the reverse rotation direction with respect to the rear end wall 34, and can finely adjust the front and rear positions of the assembly state of the guide tube 30 to conform to different internal structural specifications of various pneumatic power guns.

By uncovering the structural composition and technical characteristics of the structure, the state of the steady flow structure A disclosed in the present invention is installed at the position of the post-shooting position of the bullet 11 installed in the barrel 10 of the pneumatic power gun as shown in Fig. 3. As shown, the rear end wall 34 of the barrel 31 of the draft tube 30 can be restrained by a pin 60 having a front end opening 33 and a shoulder portion of the intake guide tube 30. Between the two, a return spring 70 can be arranged to elastically support the guide tube 30. In the present operation, when the air pressure is introduced by the air pressure introduction hole 21 provided in the air guide guide 20, the radial direction is sequentially passed through the radial direction. The through hole 35 is introduced and guided into the flow guiding channel 32 of the guiding tube 30 by the guiding of the tapered guiding portion 50, and then passes through the steady flow end 40, when the air pressure passes through the steady flow end 40. When the split air guiding passage 43 formed between the splitter pieces 42 is formed, a uniform distributed path state is exhibited, so that the air pressure can uniformly push the firing bullet 11 (as shown in FIG. 4), and the steady flow end One end of the head 40 connecting rod cylinder 41 and the front end opening 33 of the draft tube 30 barrel 31 have a separation distance W (as shown in Fig. 3) The type design is such that the inertial airflow formed by the flow guiding passage 32 of the guiding tube 30 is smoothly transmitted through the steady flow end 40; then, when the bullet 11 is passed through the steady flow end 40 After the firing is pushed, because the air pressure in the barrel 10 and the draft tube 30 is instantaneously released, the negative pressure force will drive the draft tube 30 forward until its radial through hole 35 is pushed by the wall of the intake guide tube 20. The blocked air is closed. At this time, the re-entered air pressure temporarily cannot enter the air guiding tube 30, and the pressure is applied to the rear end of the air guiding guide cylinder 20 to drive the machine to retreat. Then, the air guiding tube 30 is again returned to the spring 70. The top support is returned to the original position; wherein, the design of the steady flow end 40 connecting the one end of the rod cylinder 41 and the front end opening 33 of the draft tube 30 is opposite. In order to allow the steady flow end 40 to protrude forward through the return spring 70 (in an uncompressed state), and then to an outlet pipe 22 provided at the front end of the intake guide 20, thereby obtaining a better Split flow stabilization effect (Note: because the steady flow end 40 is adjacent to the front end of the draft tube 30 barrel 31 33 is easily affected by the rotation of the return spring 70 to generate turbulence).
