DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0019] Examples of the described embodiments are shown in the accompanying drawings, in which the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0020] The preferred embodiment of the simulated compression and tension dual-purpose fuse device provided by the present application is as shown in the figure Figures 1-3 As shown in the figure: a simulated compression and tension dual-purpose fuse device, comprising a fuse body 21, the bottom of the fuse body 21 is provided with a connecting pipe 22, the connecting pipe 22 and the bottom of the fuse body 21 form a cap cavity 24, and the bottom of the connecting pipe 22 is provided with an igniter 23, the top of the igniter 23 is in communication with the inside of the cap cavity 24;

[0021] The fuse body 21 has an inner cavity, and the inner cavity is further provided with a hammer 212, the head of the hammer 212 is provided with a limit block 214, the limit block 214 is installed in the inner cavity, the tail of the hammer 212 is provided with a card hole fork head 211, the outer part of the hammer 212 is provided with a hammer spring 213, one end of the hammer spring 213 is fixedly connected with the limit block 214, and the other end of the hammer spring 213 is fixedly connected with the tail of the hammer 212;

[0022] The outer wall of the fuze body 21 is integrally provided with a protruding portion 25, which is provided with a pushing groove, and a stop block 26 is arranged in the pushing groove. A pull ring pin 27 is slidably connected in the pushing groove, and a compression spring 28 is arranged on the outer wall of the pull ring pin 27. One end of the compression spring 28 is fixedly connected with the pull ring pin 27, and the other end of the compression spring 28 is fixedly connected with the stop block 26. The head of the pull ring pin 27 is beveled, and a clamping fork head 210 is fixedly connected with the clamping fork head 211. When the pull ring pin 27 is subjected to an external force, it slides along the pushing groove, and the clamping fork head 210 and the clamping fork head 211 are engaged with each other, so that the firing pin 212 loses control, thereby activating the firing pin 212 to move downward and strike the igniter 23 in the primer cavity 24, thereby completing the ignition process. At this time, the design of the protruding portion 25 makes the operation more convenient and can quickly adapt to various complex environments. In this embodiment, the movement trajectory of the pull ring pin 27 is carefully designed to ensure stability and reliability in complex environments. In addition, the material selection of the connecting pipe 22 is also critical, which needs to withstand forces from different directions while maintaining good sealing performance.

[0023] Further, the head of the pressure head 35 is beveled and matches the slope of the pull ring pin 27. The design of the slope of the pressure head 35 aims to increase the force transmission efficiency. When the pull ring pin 27 is pushed by an external force, the pressure head 35 can effectively guide the external force through the matching of the slope with the pull ring pin 27, so that the action of the firing pin 212 is more rapid and accurate. At the same time, this design also reduces the risk of misoperation caused by uneven external force, and improves the reliability and safety of the entire fuze device. In addition, under the design of the compression spring 28, the sliding process of the pull ring pin 27 is well buffered, so that the sensitivity of the pressure is effectively moderated, further ensuring the stability of the firing pin 212 when striking the igniter 23, and effectively improving the success rate of ignition.

[0024] The upper body of the fuze body 21 is provided with a pressure groove connected with the inner cavity. A piston rod 31 is slidably connected in the pressure groove, and a touch 33 is arranged on the top of the piston rod 31. A pressure head 35 is arranged on the bottom of the piston rod 31, and the head of the pressure head 35 is beveled and matches the slope of the pull ring pin 27. A spring 32 is arranged on the outer wall of the piston rod 31, and one end of the spring 32 is fixedly connected with the piston rod 31, and the other end of the spring 32 is fixedly connected with the bottom of the pressure groove. When the pressure head 35 is subjected to an external force, the piston rod 31 will slide along the pressure groove, and the slope on the pressure head 35 will move relative to the slope on the pull ring pin 27, so that the firing pin 212 loses control, further enhancing the reliability of the ignition process. This design enables the device to maintain high performance in various environments, such as harsh weather and extreme temperature conditions. At the same time, by optimizing the matching precision of the piston rod 31 and the pressure groove, the stability and durability of the overall structure are further improved.

[0025] The fuze body 21 is further provided with an upper safety pin 34 and a lower safety pin 29, the upper body section of the fuze body 21 and the top of the piston rod 31 are both provided with an upper safety pin hole and are fitted with the upper safety pin 34, and the protruding section 25 on the fuze body 21 and the pull ring bolt 27 are both provided with a lower safety pin hole and are fitted with the lower safety pin 29.

[0026] In the embodiment, the operation mechanism of the compression and pull dual-purpose fuze device is simulated, the precise ignition of the fuze under compression and pull actions is realized through the above structure design, and the stability and reliability of the fuze are improved.

[0027] In use, the upper safety pin 34 and the lower safety pin 29 are withdrawn in advance, when the feeler 33 on the fuze device is subjected to sufficient pressure or the pull ring bolt 27 is subjected to sufficient tension, the piston rod 31 moves downward, the pressure head 35 descends, the relative movement between the inclined surface on the pressure head 35 and the inclined surface on the pull ring bolt 27 occurs, that is, the pressure head 35 will push the pull ring bolt 27 to move outward under the action of the compression spring 28, the catch head 210 on the pull ring bolt 27 is separated from the catch hole head 211 on the firing pin 212, the firing pin 212 loses control, moves downward under the stretching force of the firing pin spring 213, and hits the primer, so that the igniter 23 ignites and detonates.

[0028] Finally, it should be noted that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced.
