Detailed Description
The invention is further described below with reference to the accompanying drawings.
The structure of the regulator 1 of this embodiment is shown in fig. 1, where two positioning arms 102 are provided, and positioning protrusions 103 are provided in front of the positioning arms. The thickness of the positioning arm is controlled to have certain elasticity. Two pairs of 4 regulator bleed holes 104 are provided in the regulator. Optimally, the scheme is provided with the T-shaped groove 105 below the regulator, and when the regulator is hotter or the manual force can not finish the regulation, the bottom edge of the cartridge case can be clamped into the T-shaped groove, and the cartridge case is pulled to regulate.
An outer circle 201 is arranged on the air guide hoop 2 and matched with the inner hole 101 of the regulator, one or more air guide hoop air release holes 202 are arranged on the outer circle 201, the diameter of each air release hole is determined by the minimum energy of the air guide mechanism, and the air release holes can be optimally and symmetrically arranged on the left side and the right side of the air guide mechanism. More than 2 positioning pits are provided in front of the air guide for cooperation with positioning protrusions 103 on the regulator, as shown in fig. 2.
After the regulator is in place, as shown in fig. 3, the regulator 1 can be rotated on the air guide hoop 2 about the outer circumferential axis. The pilot hole 202 and the regulator hole 104 are located on a single cross section, and the locating boss 103 is located in a locating recess 203 on the pilot. When the adjuster rotates, the positioning protrusion 103 needs to deform the positioning arm 102 to release from the positioning pit 203, so that the adjuster has certain positioning capability and can not rotate except manual adjustment.
The regulator is provided with bleed holes with different sizes, and for convenience of explanation, the bleed holes are respectively number 1 bleed holes and number 2 bleed holes.
When the regulator is in the position shown in fig. 4, the air guide hoop air release hole 202 is blocked by the regulator, and the mechanism cannot release air, so that all the gunpowder gas introduced by the air guide mechanism is used for pushing the automaton at the moment, and the energy provided by the air guide mechanism is maximum.
When the regulator is in the position shown in fig. 5, the bleed hole 202 of the air guide hoop is aligned with the bleed hole No. 1 on the regulator, and because the diameter 104 of the bleed hole No. 1 on the regulator is smaller than the diameter 202 of the bleed hole on the air guide hoop, the amount of bleed is determined by the bleed hole 104 of the regulator, the amount of bleed is smaller at this time, and a part of gunpowder gas escapes from the bleed hole, at this time, the energy which can be provided by the air guide mechanism is smaller than that in the state of fig. 4.
When the regulator is in the position shown in fig. 6, the bleed hole 202 of the air guide hoop is aligned with the bleed hole No. 1 on the regulator, and because the diameter 104 of the bleed hole No. 1 on the regulator is larger than the diameter 202 of the bleed hole on the air guide hoop, the bleed amount is determined by the bleed hole 202 of the air guide hoop, the bleed amount is maximum at this time, and more gunpowder gas escapes from the bleed hole than in the state of fig. 5, and at this time, the energy which can be provided by the air guide mechanism is smaller than in the state of fig. 5.
The regulator is integrally processed by a material with certain elasticity, such as spring steel or other alloys, and is provided with an inner hole for being matched with the air guide hoop, one or more positioning arms are arranged, protrusions are arranged on the positioning arms for positioning, and more than two pits are arranged at corresponding positions on the air guide hoop and are matched with the protrusions on the positioning arms. One or more air release holes are arranged on the air guide hoop, one or more air release holes are also arranged at the corresponding positions of the regulator, and after the diameters of the air release holes are matched, the energy regulation of the air guide mechanism can be realized through different combinations.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
