Description

Technical Field

[0001] This utility model relates to the field of military teaching and training equipment, and in particular to a simulated landmine. Background Technology

[0002] In the field of military teaching and training, simulated landmines are important training tools used to simulate the triggering and explosion effects of landmines in real combat environments, so as to improve soldiers' battlefield identification, bomb disposal and tactical response capabilities. Simulated landmines in existing technologies are usually composed of a shell, explosive charge, ignition device and triggering mechanism. Their core requirements are safety and reliability, simulation realism and ease of operation.

[0003] However, traditional ignition methods are easily affected by environmental conditions. Humid environments may cause poor circuit contact, and low temperatures may reduce the sensitivity of the ignition charge. For example, exposed firing pins are easily damaged by impacts. Furthermore, during transportation, storage, or pre-training preparation, if subjected to vibration, accidental activation, or environmental interference, the ignition device may be accidentally activated and ignite the charge, causing the simulated explosion to occur prematurely, posing a safety hazard to operators and training sites. Therefore, these methods have certain shortcomings. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1: This utility model provides the following... Figures 1-4 The simulated landmine shown includes an inner shell 1, a propellant charge 2, an end cap 3, an ignition assembly 4, a detonation blocking mechanism 5, and an outer shell 6. The propellant charge 2 is fitted inside the inner shell 1, and the end cap 3 is installed on the top of the inner shell 1. The end cap 3 is used to shield and protect the propellant charge 2. The propellant charge 2 is composed of a shell, gunpowder, sawdust, black powder, and a fuse. The gunpowder, sawdust, black powder, and fuse are arranged from top to bottom inside the shell. Figure 2 As shown, the fuse corresponds to the ignition assembly 4. The propellant charge 2 operates on the same principle as fireworks. When the fuse is lit, it ignites the black powder. The ignition of the black powder gives the casing a thrust, causing the propellant charge 2 to eject from the inner casing 1. The black powder ignites the gunpowder through sawdust, causing the propellant charge 2 to explode. This is existing technology and will not be discussed in detail here. This simulates a landmine explosion. The ignition assembly 4 is located on the inner casing 1 and is used to ignite the propellant charge 2. The detonation blocking mechanism 5 is located between the ignition assembly 4 and the propellant charge 2. During transportation and storage, the detonation blocking mechanism 5 can prevent the ignition assembly 4 from igniting the propellant charge 2, thereby improving the safety of the propellant charge 2 during transportation and storage. The outer casing 6 is threaded onto the outside of the inner casing 1. The outer casing 6 can ensure the stability of the installation of the ignition assembly 4 and the detonation blocking mechanism 5.

[0045] Specifically, the bottom of the end cap 3 is provided with a circular ring 7, which is slidably sleeved between the inner shell 1 and the propellant charge 2. The outer wall of the circular ring 7 is fixedly connected to a limiting sleeve 8. A limiting groove is opened at the top inside the inner shell 1. The outer wall of the limiting sleeve 8 is slidably engaged with the inner cavity of the limiting groove. The limiting sleeve 8 can improve the stability of the connection between the circular ring 7 and the inner shell 1. Furthermore, the friction between the limiting sleeve 8 and the inner shell 1 is greater than the weight of the propellant charge 2 and much less than the lifting force when the propellant charge 2 is launched, thereby improving the stability of the end cap 3 in shielding and protecting the propellant charge 2.

[0046] Furthermore, the ignition assembly 4 includes a base plate 41, a heating resistor 42, and an ignition charge 43. The bottom of the inner housing 1 is provided with a mounting groove, and the base plate 41 is slidably fitted into the inside of the mounting groove. The heating resistor 42 is fixedly installed on the top of the base plate 41. The top of the inner wall of the mounting groove is provided with a mounting hole corresponding to the heating resistor 42. The ignition charge 43 is placed inside the mounting hole and is wrapped around the outside of the heating resistor 42. When the heating resistor 42 is energized or generates heat, it ignites the ignition charge 43, which in turn ignites the propellant column 2.

[0047] Furthermore, the ignition assembly 4 also includes an electrode plate 44, a conductive plate 45, and an arc-shaped pad 46. The electrode plate 44 is fixedly connected to the bottom of the base plate 41 and is electrically connected to the pins of the heating resistor 42. The conductive plate 45 is fixedly installed inside the outer casing 6. The conductive plate 45 and the electrode plate 44 are pressed together and adhered to each other. The two electrode plates 44 are respectively in the shape of a ring and a disk. So when the outer casing 6 and the inner casing 1 are rotated together, the two conductive plates 45 can contact the two electrode plates 44 individually, thereby avoiding short circuits or open circuits. The arc-shaped pad 46 is fixedly connected to the inner wall of the bearing groove. The outer wall of the arc-shaped pad 46 is slidably engaged with the base plate 41. The arc-shaped pad 46 can improve the stability of the base plate 41 installed inside the bearing groove.

[0048] In particular, the detonation mechanism 5 includes a partition 51 and a restraint assembly. A connection hole is provided on one side of the inner housing 1. The outer wall of the partition 51 is slidably inserted into the inner cavity of the connection hole. The partition 51 is located between the propellant column 2 and the ignition powder 43. The partition 51 is made of a material with good heat insulation performance to reduce the chance of the ignition powder 43 accidentally igniting the propellant column 2. When the propellant column 2 is in use, the outer housing 6 needs to be disassembled and the partition 51 needs to be pulled out. A mounting groove corresponding to the restraint assembly is provided on one side of the inner housing 1. The restraint assembly is used to limit and restrain the partition 51.

[0049] Furthermore, the restraint assembly includes a connecting block 521, a first magnet 522, and a second magnet 523. The top of the connecting block 521 is fixedly connected to the partition 51, and a notch is provided at the bottom of the connecting block 521. The first magnet 522 and the second magnet 523 are respectively fixedly embedded in the connecting block 521 and the inner shell 1. The opposite magnetic poles of the first magnet 522 and the second magnet 523 are opposite to each other. The first magnet 522 and the second magnet 523 can limit the position of the connecting block 521, thereby improving the stability of the partition 51 installation. Moreover, the connecting block 521 and the partition 51 can be directly pulled out using the notch at the bottom of the connecting block 521.

[0050] Example 2: Unlike Example 1, as follows... Figure 5As shown, the restraint assembly includes a connecting frame 524, a locking rod 525, a connecting plate 526, a handle 527, a guide rod 528, and a limiting spring 529. The top of the connecting frame 524 is fixedly connected to the partition plate 51. The outer wall of the locking rod 525 is slidably inserted into the connecting frame 524. A locking groove is provided at the bottom of the inner wall of the mounting groove. The bottom of the outer wall of the locking rod 525 is slidably engaged with the inner cavity of the locking groove. The connecting plate 526 is fixedly connected to the top of the locking rod 525. The handle 527 is fixedly connected to the top of the connecting plate 526. The handle 527 can be used to move the rod. The connecting plate 526 and the locking rod 525 rise, thereby separating the locking rod 525 from the inner housing 1, and thus pulling out the partition 51. The guide rod 528 is fixedly connected to the inside of the connecting frame 524. The outer wall of the guide rod 528 is slidably inserted into the connecting plate 526. The limiting spring 529 is slidably sleeved on the outside of the guide rod 528. The limiting spring 529 is located at the top of the connecting plate 526. Under the action of the limiting spring 529, the connecting plate 526 can drive the locking rod 525 to be in a stable state and locked with the inner housing 1, thereby ensuring the stability of the partition 51 installation.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
