Detailed Description

The technical solution in the embodiments of the present invention is clearly and completely described below with reference to the drawings in the embodiments of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 6, a dual-wire trigger firing head structure of the present invention comprises a front ring body 1 and a rear cone body 2 which is retracted backward, a rear half external thread 10 of the front ring body 1 can be connected to an internal thread 30 at the front end of a firing body 3 by means of a close-fitting ring 29, a partition plate 11 is transversely arranged at the middle horizontal diameter of the front ring body 1, a through hole 12 is arranged at the center of the partition plate 11, a fixing screw 21 can pass through the through hole 12 to be locked to a screw hole 22 correspondingly arranged at the center of the rear cone body 2, and the rear cone body 2 is connected to the front ring body 1; in addition, the upper half and the lower half of the front ring sleeve body 1 are respectively provided with a hole seat 13, a projectile body 15 containing a double-section columnar counterweight connected with one end of a rope 14 (one of the two is shown in the figure 3 that a rope hole 32 transversely penetrates through one side of the lower half body of the projectile body 15 to enable the rope 14 to penetrate through and then to be tied into a whole) is respectively placed in each hole seat 13, the front end of the projectile body 15 is locked with a claw 28 through a screw 27 (a hole 26 is arranged in the claw 28 and is locked into a screw hole 25 at the top end of the projectile body 15 through the screw 27), each rope 14 in the upper half and the lower half penetrates through a cutting seam 16 oppositely arranged beside the hole seat 13 and is connected in pairs to form a rope 14 to be embedded into an upper half middle section space 17 and a lower half middle section space 18; an air outlet 23 is arranged at each hole seat 13 of the rear cone sleeve body 2 relative to the front ring sleeve body 1, a diaphragm 24 is arranged between the air outlet 23 and the hole seat 13, when the air of the launching body 3 is started forward, the diaphragm 24 can be broken to enable each pair of projectiles 15 to fly forward respectively, and two pairs of the ropes 14 and the projectiles 15 are enabled to fly forward in parallel to each other until the two pairs of the ropes touch a human body to rotate, the ropes 14 are hooked by a claw 28 to generate the function of tripping the escapement, a cover plate 20 is arranged at the front end of the front ring sleeve body 1 and is clamped by a lantern ring 19 (a pair of protruding points are arranged on the lantern ring 19 to clamp a pair of grooves arranged on the outer surface of the front ring sleeve body 1), and the cover plate 20 is broken at the same time of launching (the launching body 3 launches the projectiles 15 and launches). When the projectile body 15 is integrally formed, as shown in fig. 3, a side rope hole 32 is formed around the projectile body 15 to allow the rope 14 to be fixed by being tied, and a rope holding groove 31 is formed around the projectile body 15. In addition, the projectile body 15 is two-piece, as shown in fig. 3A and 3B, the projectile body 15 has a bottom piece 33 with a large diameter and a top piece 34 with a small diameter, the top piece 34 is inserted into a middle slot 35 fixed on the top surface of the bottom piece 33, before the rope 14 is threaded through a bottom rope hole 36 of the bottom piece 33, the bottom rope hole 36 is communicated with a fixed slot 39 at the middle section inside the screw hole 25 of the top piece 34, the bottom rope hole 36 is communicated with a thin through hole 37 at the bottom end of the fixed slot 39, the diameter of the thin through hole 37 is the same as that of the bottom rope hole 36, and the rope 14 is fixed at the fixed slot 39 under the screw hole 25 by a bundle of rope sleeve 38 after being threaded through the thin through hole 37; and the periphery of the projectile body 15 is provided with a rope placing groove 31. When the projectile body 15 is in a separated type, it can fly forwards under the state of counterweight, when touching human body, because the weight of the bottom piece 33 will automatically separate as the rocket is used up, the top piece 34 will generate the counteracting rotational acceleration force, and further after the ring-shaped rotation, the gripper 28 will catch the rope 14 very quickly to generate the definite binding action.

In summary, the present invention uses a specially designed partition 11 to divide the front ring housing 1 into two halves, and a rope 14 containing two projectiles 15 is provided to fly horizontally as shown in fig. 6.

It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
