[0032] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0033] Figures 1 to 8 The overall structural schematic diagram of this embodiment is shown. Attached Figure 1It is shown that a new type of hydraulic cartridge extractor includes an extraction cylinder 14, a pressure-bearing rubber hose 3, a blocking plate 4, and a hydraulic converter 6. The extraction cylinder 14 has a hollow structure. The hydraulic converter 6 is located on one side of the blocking plate 4, and its axially movable free end faces the extraction cylinder 14; the axial center of the hydraulic converter 6 coincides with the axial center of the extraction cylinder 14. One end of the connecting pipe 8 with a long axis is connected to the extraction cylinder 14, and the other end in the long axis direction of the connecting pipe 8 is connected to the end of the axially movable free end of the hydraulic converter 6. One end of the pressure-bearing rubber hose 3 passes through the blocking plate 4 and is connected to the liquid inlet interface of the hydraulic converter 6. Among them, during use, the hydraulic cartridge extractor is located inside the combined structure of the gun barrel 13 and the muzzle brake 1. The other end of the pressure-bearing rubber hose 3 is connected to the recoil device inspection and treatment tool 2. The blocking plate 4 is clamped near the inner side of the end of the muzzle brake 1, so that the hydraulic converter 6 cannot axially sway left and right inside the muzzle brake 1 under certain circumstances; a projectile 15 is placed inside the hollow structure of the extraction cylinder 14; during cartridge extraction, the fuse 151 of the projectile 15 is inside the hollow structure of the extraction cylinder 14, and the edge of the extraction cylinder 14 contacts the outer surface of the projectile 15 to ensure that there is an accommodation space between the fuse 151 and the extraction cylinder 14; shake the handle of the recoil device inspection and treatment tool 2 to pump the hydraulic medium into the hydraulic converter 6, causing the axially movable free end of the hydraulic converter 6 and the connected connecting pipe 8 and extraction cylinder 14 to move, and pushing the projectile 15 out of the gun barrel 13. In this embodiment, due to the addition of the blocking plate 4, the hydraulic converter 6 will not axially sway left and right, thereby reducing the thrust loss during the operation of the new type of hydraulic cartridge extractor and improving the cartridge extraction efficiency to a certain extent.

[0034] It should be noted that in this embodiment, to ensure that when the handle of the recoil device inspection and treatment tool 2 is shaken to pump the hydraulic medium into the hydraulic converter 6, causing the axially movable free end of the hydraulic converter 6 and the connected connecting pipe 8 and extraction cylinder 14 to move, the pressure-bearing rubber hose 3 does not burst, it is necessary to select a plastic hose with better pressure-bearing capacity, such as a plastic hose with a pressure resistance value ≥ 6 Mpa, or a plastic hose with reinforcing fibers or reinforcing steel wires inside.

[0035] In this embodiment, the hydraulic cartridge extractor is provided with a blocking plate 4. Specifically, as shown in the appendix Figure 4As shown in the figure, the baffle plate 4 includes a sixth side portion 44 and a seventh side portion 45. There is a gap between the sixth side portion 44 and the seventh side portion 45, and both the sixth side portion 44 and the seventh side portion 45 are in the shape of a cuboid. One end of the sixth side portion 44 is connected to a seventh end portion 43. The seventh end portion 43 is in the shape of a cuboid, and an arc-shaped groove is provided at the corner of the seventh end portion 43 facing the seventh side portion 45. The other end of the sixth side portion 44 is connected to a fifth end portion 41, and the fifth end portion 41 is generally in an L shape. The fifth end portion 41 straddles the gap between the sixth side portion 44 and the seventh side portion 45, and a part of the fifth end portion 41 is connected to the end face of the seventh side portion 45; the remaining part of the fifth end portion 41 is connected to the outer side edge of the seventh side portion 45. The outer side edge of the seventh side portion 45 is the side of the seventh side portion 45 opposite to the sixth side portion 44. A groove is provided on the surface of the fifth end portion 41 facing the gap. The groove starts from the inner side edge of the sixth side portion 44 and ends at the inner side edge of the seventh side portion 45. One end of the seventh side portion 45 opposite to the connection with the fifth end portion 41 is connected to a sixth end portion 42, and an arc-shaped groove is provided at the corner of the sixth end portion 42 facing the sixth side portion 44. Arc-shaped grooves are provided on the opposite end faces of the fifth end portion 41 and the sixth end portion 42. In addition, there is a gap between the opposite end faces of the seventh end portion 43 and the sixth end portion 42. A first convex portion 47 is connected to the inner side edge of the sixth side portion 44 near the seventh end portion 43, and arc-shaped grooves are provided on both sides of the first convex portion 47; on the end face of the seventh side portion 45 opposite to the sixth side portion 44, a second convex portion 48 identical to the first convex portion 47 is provided, and there is a gap between the first convex portion 47 and the second convex portion 48. One end of the inner side edge of the sixth side portion 44 near the fifth end portion 41 is connected to one end of a blocking portion 46, and the other end of the blocking portion 46 is connected to the inner side edge of the seventh side portion 45. The blocking portion 46 is in the shape of a cuboid, and grooves identical to those of the fifth end portion 41 are provided on both side edges of the blocking portion 46. Among them, there are gaps between the blocking portion 46 and the first convex portion 47 and the second convex portion 48, and one end of the pressure-bearing rubber hose 3 passes through the gap and is connected to the hydraulic converter 6. Due to the setting of the baffle plate 4, the movement of the hydraulic converter 6 in the direction of the pressure-bearing rubber hose 3 can be prevented, the loss of thrust is reduced, and the efficiency of the hydraulic cartridge extractor is thus improved.

[0036] In this embodiment, the hydraulic converter 6 includes a hydraulic cylinder 63, a piston 65, and a piston rod 7. Specifically, as shown in the attached Figure 6As shown, the hydraulic cylinder 63 has a hollow structure, and the inner surfaces at both ends of the hydraulic cylinder 63 are respectively connected with a front cover 66 and a rear cover 62. Both ends of the front cover 66 and the rear cover 62 are open; the pressure-bearing rubber hose passes through the rear cover 62, and a pressure-bearing joint 5 is arranged in the middle of the pressure-bearing rubber hose. The pressure-bearing joint 5 is generally selected as a DN19 male / KJ19 female conversion joint, and the pressure-bearing joint 5 is made of steel or stainless steel. Among them, the pressure-bearing rubber hose 3 is connected with the liquid inlet interface of the hydraulic converter 6. The pressure-bearing joint 5 is used to bear the pressure at the connection between the pressure-bearing rubber hose 3 and the hydraulic converter 6 to prevent bending at the connection. A tight plug ring 61 is connected to the inner surface of the through hole of the rear cover 62 to make the connection between the pressure-bearing rubber hose and the hydraulic converter 6 more stable. The inner surface in the middle of the hydraulic cylinder 63 is in sliding contact with the piston 65. Several O-rings 68 and retaining rings 69 are embedded in a partial area of the piston 65 close to the inside of the hydraulic cylinder 63. In addition, an installation groove 67 is formed on the end face of the piston 65 facing the second end 12. A piston rod 7 is connected in the installation groove 67. Specifically, one end of the piston rod 7 is connected with the installation groove 67 of the piston 65, and the other end of the piston rod 7 is connected with a connecting pipe 8. Optionally, an outer sleeve 64 is arranged on the outer surface of the hydraulic cylinder 63. The outer sleeve 64 is generally made of soft materials such as rubber and can play a role in shock absorption. Thus, by changing the stroke of the piston 65, the transmission of thrust can be realized.

[0037] In this embodiment, the hydraulic converter 6 is connected with the cartridge ejector cylinder 14 through the connecting pipe 8, and the axial center of the hydraulic converter 6 coincides with the axial center of the cartridge ejector cylinder 14. Specifically, the axial length direction of the connecting pipe 8 includes a first side portion 81 and a second side portion 82 facing the second end 12, and the piston rod 7 is connected with the first side portion 81; in addition, the second side portion 82 of the connecting pipe 8 is located inside the gun barrel 13, and the second side portion 82 is connected with the cartridge ejector cylinder 14. Specifically, a fixing ring 9 is arranged between the first side portion 81 and the second side portion 82 of the connecting pipe 8. The specific structure of the fixing ring 9 is as shown in the appendix Figure 7As shown, the middle part of the fixing ring 9 has an inner hole 91, and the outer diameter of the inner hole 91 is equal to or slightly larger than the diameter of the connecting pipe 8. The outer peripheral surface of the fixing ring 9 is called the thick end 92. Exemplarily, the fixing ring 9 is likened to a clock, and threaded holes 93 are respectively opened from the 12 o'clock, 8 o'clock, and 4 o'clock directions of the thick end 92 towards the position of the inner hole 91. Then, screws (not marked in the figure) are arranged at the positions of these three threaded holes 93, and the screws are screwed into the threaded holes 93 so that the screws abut against the outer peripheral surface of the connecting pipe 8. Of course, those skilled in the art can open the threaded holes 93 at different positions, as long as the threaded holes 93 are opened on the fixing ring 9 to play a role in fixing the connecting pipe 8. Exemplarily, 4 of the aforementioned fixing rings 9 are arranged on the outer surface of the connecting pipe 8. Optionally, 6 through holes are also opened around the inner hole 91, and the purpose of this is to reduce the weight of the entire hydraulic cartridge extractor. The second side portion 82 of the connecting pipe 8 is connected to the fifth side portion 141 of the cartridge case ejector 14, and among them, the second side portion 82 and the fifth side portion 141 are connected through a quick connector 16. In addition, the connecting pipe 8 and the fixing ring 9 in this embodiment are both made of high-strength aluminum alloy. For high-strength aluminum alloy, generally, aluminum alloy with a tensile strength higher than 480 Mpa is called high-strength aluminum alloy. Thus, the setting of the fixing ring 9 makes the connecting pipe 8 of the hydraulic cartridge extractor not easily radially shake up and down in the muzzle brake 1, thereby improving the stability of the overall structure of the hydraulic cartridge extractor.

[0038] In this embodiment, the cartridge case ejector 14 includes a transmission part 142 and a cartridge case part 144. Specifically, the cartridge case ejector 14 is located inside the gun barrel 1. The fifth side portion 141 of the cartridge case ejector 14 facing the second end portion 12 is connected to the connecting pipe 8 through a pressure-bearing joint 5. Relevant explanations have been made before and will not be elaborated here. The structure of the fifth side portion 141 facing the fourth side portion 132 is successively a transmission part 142, a first ring part 143, a cartridge case part 144, and a second ring part 14. Among them, the fifth side portion 141 belongs to the structure of the transmission part 142. The first ring part 143 is a hollow structure, and the two sides of the first ring part 143 are the transmission part 142 and the cartridge case part 144. Among them, the cartridge case part 144 is a hollow cylindrical shape. A plurality of holes are opened on the outer surface of the cartridge case part 144, and the specific number is not limited. In addition, at one end of the cartridge case part 144 opposite to the first ring part 143, a second ring part 14 identical to the first ring part 143 is connected. For the description of the structure of the second ring part 14, reference can be made to the relevant content in the aforementioned first ring part 143. Thus, when using this embodiment, the thrust generated by the hydraulic converter 6 can be transmitted into the cartridge case ejector 14, and then the projectile 15 in the cartridge case ejector 14 can be pushed out of the gun barrel 13 to realize the operation of safe cartridge extraction.

[0039] In use, the hydraulic converter 6 is installed inside the muzzle brake 1, and the hydraulic converter 6 of the hydraulic cartridge extractor is connected to the recoil device inspection and treatment tool 2. Specifically, the recoil device inspection and treatment tool 2 includes a connecting portion 21. On the opposite side of the connecting portion 21 is the muzzle brake 1, which is of a hollow structure; the axial length direction of the muzzle brake 1 includes a first end 11 and a second end 12, and both the first end 11 and the second end 12 are open. As can be seen from the appendix Figure 2 There are several windows 13 on the inner wall surface of the muzzle brake 1. The hydraulic converter 6 is arranged on the side of the baffle 4 facing the second end 12. The fifth end 41 of the baffle 4 penetrates into the muzzle brake 1 through the window until it stops when the surface of the fifth end 41 opposite to the sixth end 42 contacts the outer surface of the muzzle brake 1, so that the baffle 4 is clamped on the window 13 of the muzzle brake 1. This window 13 can be the first window 13 near the first end 11 of the muzzle brake 1 or the second window 13 near the first end 11, and no specific limitation is made here. One end of the pressure-bearing hose 3 facing the recoil device inspection and treatment tool 2 is the third end 31, and the end opposite to the third end 31 is the fourth end 32; among them, the third end 31 is connected to the connecting portion 21 through the pressure-bearing joint 5. The fourth end 32 extends into the interior of the muzzle brake 1, then penetrates through the baffle 4 and is connected to the liquid inlet interface of the hydraulic converter 6 through the pressure-bearing joint 5, and this pressure-bearing joint 5 is used to bear the liquid pressure at the connection between the pressure-bearing hose 3 and the hydraulic converter 6. Those skilled in the art should know that the projectile 15 is arranged inside the gun barrel 13. Specifically, the projectile 15 is arranged inside near the fourth side portion 132, and a partial area on the outer surface of the projectile 15 is in close contact with the inner wall surface of the gun barrel 13. The width formed from the edge of this partial area to the fuse 151 gradually becomes smaller, and there is an accommodation space between the fuse 151 and the transmission portion 142.
