Technical Field
[0001] This invention relates to a low-cost, high-strength training round structure, belonging to the field of full-ball structure technology for small-caliber ammunition. Background Technology
[0002] During the development of training rounds, researchers found that the existing training rounds have poor structural strength. After multiple uses, the connection between the projectile and the cartridge case is prone to loosening and separation, failing to meet the technical requirement of at least 30 uses. In addition, the procurement cost of the cartridge case is high.
[0003] Therefore, in order to reduce costs and solve the problem that the connection between the projectile and the cartridge case is prone to loosening and separation after multiple uses of training rounds, a low-cost, high-strength training round structure is proposed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a low-cost, high-strength training missile structure.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A low-cost, high-strength training round structure includes a projectile core, an integrated cartridge support, and a cartridge base. The projectile core and the cartridge base are respectively threaded at both ends of the integrated cartridge support. The integrated cartridge support has a cartridge band groove, in which a cartridge band is installed. The cartridge base has a threaded hole three at the middle of the end away from the integrated cartridge support, and a primer is internally threaded into the threaded hole three.
[0006] Furthermore, the integrated cartridge case includes a cartridge case and a cartridge case, which are integral structures. The outer surface of the cartridge case has a cartridge band groove, the cartridge band is installed in the cartridge band groove, the cartridge core is threaded to the end of the cartridge case, and the bottom of the cartridge case is threaded to the end of the cartridge case.
[0007] Furthermore, a threaded hole is provided at the center of the end of the core, and a threaded post is provided at the end of the support, the threaded post being threadedly connected and fixed to the threaded hole.
[0008] Furthermore, a second threaded hole is provided at the center of the end of the cartridge, and an external thread is provided on the outer surface of the bottom of the cartridge, which is threadedly connected to the second threaded hole.
[0009] Furthermore, threadlocker is applied to the threaded connection between the threaded post and the first threaded hole, the threaded connection between the external thread and the second threaded hole, and the threaded connection between the third threaded hole and the primer.
[0010] Furthermore, the cartridge belt includes an outer cartridge belt and an inner cartridge belt, the inner cartridge belt being installed inside the cartridge belt groove, and the outer cartridge belt being installed outside the inner cartridge belt.
[0011] Furthermore, both the inner and outer spring bands are fixed within the spring band groove by pressing.
[0012] Furthermore, the outer surface of the bullet core and the outer surface of the cartridge bottom are respectively provided with anti-slip texture one and anti-slip texture two, and the outer surface of the cartridge is provided with a groove, and a plurality of anti-slip blocks are provided in the groove, the anti-slip blocks being a hexagonal pyramid structure.
[0013] The beneficial effects of this utility model are: This utility model features an integrated cartridge case and cartridge case design, where the cartridge case and cartridge case are connected as one unit. This eliminates the need for joining and tightening during assembly, thereby improving the strength of the training cartridge and meeting the technical requirement of at least 30 uses.
[0014] This utility model, through the design of anti-slip texture one, anti-slip texture two, and anti-slip block, not only facilitates the user's handling of the training rounds but also facilitates their disassembly. At the same time, as the main point of force application, the hexagonal pyramidal anti-slip block on the outer surface of the cartridge increases the contact area with the user, making it easier for the user to apply force and perform disassembly.
[0015] The integrated cartridge case of this utility model is machined, and the shape of the cartridge case is consistent with that of the purchased cartridge case. The inner cavity is hollowed out so that the weight is consistent with that of the purchased cartridge case. The machined cartridge case significantly reduces the cost compared to the purchased cartridge case. It also optimizes the structure of the traditional training cartridge and reduces some parts, thereby reducing the manufacturing cost of the training cartridge case. Attached Figure Description
