Description

Technical Field

[0001] This application relates to the field of anti-recoil technology for military individual-carried weapons, such as an anti-recoil mechanism. Background Technology

[0002] Currently, the main anti-recoil mechanism of individual weapon systems is the base plate mechanism, which consists of parts such as a sling ring, stiffener, mortise, trapezoidal main plate, and carrying handle. During firing, it bears the recoil force and distributes this force to the soil. By relying on the resistance of the soil, it achieves anti-recoil against the firing barrel, ensuring the continuity and stability of firing.

[0003] However, this anti-recoil mechanism requires the barrel to be installed on soil with a certain degree of looseness. Once it encounters hardened cement ground, its shooting effect is greatly reduced, and it may even deviate from the target or be damaged, which greatly limits the range of use of the weapon. Utility Model Content

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0027] Currently, the main anti-recoil mechanism of individual weapon systems is the base plate mechanism, which consists of parts such as a sling ring, stiffener, mortise, trapezoidal main plate, and carrying handle. During firing, it bears the recoil force and distributes this force to the soil. By relying on the resistance of the soil, it achieves anti-recoil against the firing barrel, ensuring the continuity and stability of firing.

[0028] However, this anti-recoil mechanism requires the barrel to be installed on soil with a certain degree of looseness. Once it encounters hardened cement ground, its shooting effect is greatly reduced, and it may even deviate from the target or be damaged, which greatly limits the range of use of the weapon.

[0029] Therefore, the design concept of this application is to design a device that can replace soil as the discharge material for the cannon barrel, so that it is no longer limited to soil use and can be used in a wider range of applications.

[0030] like Figures 1-4 As shown, this application provides an anti-recoil mechanism, including a U-shaped seat 1, a buckle is provided on the base plate 2 of the U-shaped seat 1, a spring shaft 5 is provided on the buckle, a support plate 6 is rotatably provided on the spring shaft 5, and a torsion spring 7 is connected to the support plate 6; a rubber pad 8 is provided at the bottom of the base plate 2 of the U-shaped seat 1.

[0031] The buckle includes a connecting sleeve 41 that is threadedly connected to the spring shaft 5. The outer wall of the connecting sleeve 41 is connected to an ear seat 42, which is threadedly connected to the base plate 2.

[0032] In use, the ear bracket 42 is installed on the base plate 2 with screws and nuts to support the installation of the component.

[0033] The buckle includes buckle I3 and buckle II4. Buckle I3 is threaded to the front end of the spring shaft 5, and buckle II4 is threaded to the middle and rear ends of the spring shaft 5.

[0034] The front end and the middle and rear end of the spring shaft 5 are provided with external threads on their outer walls, which are threaded to the buckle. When in use, the buckle, spring shaft 5, support plate 6 and torsion spring 7 are assembled together, and then the buckle is installed on the base plate 2 using screws and nuts.

[0035] Among them, a limiting block 43 is provided on the outer wall of the connecting sleeve 41 of the buckle II4.

[0036] The limiting block 43 is a locking block with a support edge at a certain angle α (the angle of α is in the range of 85°~95°), which can prevent the support plate 6 from tilting inward. When in use, the support plate 6 can only tilt outward, thereby reducing the recoil force.

[0037] The support plate 6 has a slip ring rotatably connected to the spring shaft 5 on its side. The slip ring includes a front ring 9 rotatably connected to the front end of the spring shaft 5, a middle front ring 10 rotatably connected to the middle front end of the spring shaft 5, and a rear ring 11 rotatably connected to the rear end of the spring shaft 5. The torsion spring 5 is located between the middle front ring 10 and the buckle II 4. The slip ring can rotate and slide freely on the spring shaft 5.

[0038] The bottom of the base plate 2 of the U-shaped seat 1 has a rough surface, which is bonded to the rubber pad 8; the design of the rough surface is more conducive to the firm bonding of the rubber pad 8.

[0039] When the rocket is fired on hardened ground, the rubber pad 8 on the bottom surface of the base plate 2 can reduce the recoil.

[0040] This application relates to an anti-recoil mechanism that can be used in a certain military man-portable weapon system. This weapon system is used for over-the-horizon real-time aerial reconnaissance and target surveillance in complex terrain environments such as hills, mountains, and towns, and can carry out precision strikes against targets such as light vehicles, personnel, and battlefield command systems.

[0041] This application mainly consists of parts such as a U-shaped base 1, a support plate 6, a torsion spring 7, a buckle, and a rubber pad 8. The two buckles are used to install the support plate 6, the spring shaft 5, and the torsion spring 7 onto the base plate 2 with screws and nuts. The base plate 2 is bonded to the rubber pad 8 (the parts are threaded onto the spring shaft 5, and then the buckles I3 and II4 are installed on the base plate 2 with screws and nuts. The bottom surface of the base plate is roughened by grinding, and finally the rubber pad 8 is bonded to the bottom surface of the base plate 2). When firing, the launch tube is placed on the support plate 6. When the loitering munition is launched from the tube, it gives a certain amount of recoil force to the support plate 6, the base plate 2, and the rubber pad 8. However, the support plate 6 with the torsion spring 7 can dissipate part of the recoil force by rotating the torsion spring 7 at a certain angle. At the same time, the relatively soft rubber pad 8 is compressed and undergoes elastic deformation, which can also reduce part of the recoil force. These two effects enable the loitering munition to still achieve the required initial velocity and flight direction when it is launched.
