Description

Technical Field

[0001] The invention belongs to the technical field of ammunition detonation, and in particular relates to a linkage type internal energy storage explosion device integrating safety, locking and ignition. Background Art

[0002] Explosive devices are mainly used in military weapons for special ammunition (such as jamming ammunition). Since this type of ammunition explosive device has no external ignition energy and the ballistic environment is difficult to provide the energy required for ignition, the commonly used explosive devices that provide external ignition energy cannot be used on this type of ammunition. Only internal energy storage ignition mechanisms can be used. Conventional internal energy storage ignition mechanisms are generally coaxial with the primer and the lower-level pyrotechnics (detonators or other explosives). When the firing pin accidentally pokes the primer, the entire product will be detonated, posing certain safety hazards. Summary of the Invention

[0003] To solve the problems raised in the above background technology, the present invention provides a linked internal energy storage explosive device that integrates safety, locking, and ignition. It has the characteristics of ensuring the safety of ammunition before the safety is released, and achieving the reliability of ignition without external energy after the safety is released.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a linkage type internal energy storage explosion device integrating safety, locking and ignition, comprising a shell, wherein an operating chamber with a top opening is provided in the shell;

[0005] A slider assembly is provided in the operating chamber, comprising a slider installed in the operating chamber, one end of the slider being connected to a slider spring compression screw via a slider spring, a safety hole being provided on one side of the slider, a locking hole being provided on the other side, a placement cavity being provided on the top, a detonator being installed in the placement cavity, and a transmission groove being provided at the bottom of the slider communicating with the placement cavity;

[0006] A safety pin installed on one side of the operating chamber has one end inserted into the safety hole and the other end passing through and extending out of the side wall of the housing, and is used to fix the position of the slider in the operating chamber;

[0007] An internal energy storage ignition mechanism and a locking mechanism are installed on the other side of the operating chamber and are linked to each other. A first accommodating chamber communicating with the operating chamber is provided in the housing, and the internal energy storage ignition mechanism is arranged in the first accommodating chamber;

[0008] The housing is further provided with a second accommodating chamber communicating with the operating chamber, which is located on one side of the accommodating chamber, and the accommodating chambers 1 and 2 are communicated with each other through a limiting hole, and the locking mechanism is provided in the accommodating chamber 2;

[0009] The internal energy storage firing mechanism includes a firing pin pressure screw installed in the accommodating chamber 1, the firing pin pressure screw is connected to the firing pin through the firing pin spring, the end of the accommodating chamber 1 away from the firing pin is connected to the operating chamber, and a needle percussion cap is provided at the connection point, a limiting hole is provided in the accommodating chamber 1 near the end of the firing pin, and a safety ball is provided in the limiting hole to limit the position of the firing pin near the end of the firing pin;

[0010] The locking mechanism includes a locking pressure screw installed in the second accommodating chamber. The locking pressure screw is connected to a locking rod through a locking spring, and the end of the locking rod extends into the operating chamber close to the slider. One end of the locking rod is located at the end of the limiting hole, limiting the safety ball in the limiting hole, and the other end of the locking rod is adapted to the locking hole.

[0011] Preferably, a plurality of locking threaded holes are distributed around the operating cavity, and a cover plate is placed on the top of the shell. The cover plate is installed on the top of the shell by matching the locking threaded holes with locking bolts to cover the operating cavity.

[0012] Preferably, the locking rod consists of three cylindrical sections, the diameter of cylindrical section one is adapted to the inner diameter of the locking hole, the diameter of cylindrical section two is larger than that of cylindrical section one, and it is located at the end of the limiting hole, and the diameter of cylindrical section three is smaller than the diameter of cylindrical section one, and it is connected to the locking spring.

[0013] Preferably, the firing pin is provided with a chamfer near the safety ball.

[0014] Preferably, the locking pressure screw, the firing pin pressure screw and the slider spring pressure screw are all flat screws, and their end faces are exposed on the side wall of the shell.

[0015] Preferably, the safety holes and the locking holes on the slider are staggered.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The linked internal energy storage explosive device described in the present invention integrates safety, locking, and ignition. In the assembled state, the safety pin locks the slider, ensuring that the detonator on the slider is misaligned with the needle percussion cap of the internal energy storage ignition mechanism. At the same time, the internal energy storage ignition mechanism is constrained by the locking mechanism, making the needle percussion cap unable to activate, thereby ensuring the safety of the ammunition before the safety is released.

[0018] 2. The linked internal energy storage explosive device integrating safety, locking and ignition described in the present invention is in the aligned state, that is, the safety pin is pulled out of the shell, the safety pin cancels the constraint and fixation on the slider, and the slider spring elastically pushes the slider to move in the operating chamber until the locking hole is aligned with the locking rod, and the transmission groove is aligned with the communication between the accommodating chamber and the operating chamber, so that the locking spring elastically pushes the locking rod into the locking hole to lock the slider. At the same time, since the locking rod enters the locking hole, it cancels the restriction on the safety ball in the limiting hole, and the firing pin spring pushes the firing pin through the elastic force, so that the firing pin pushes the safety ball out of the limiting hole, and the firing pin is pushed to poke the needle piercing cap, causing it to ignite. After ignition, its energy is transmitted to the detonator through the transmission groove, causing the detonator to be detonated, and since the slider is restricted and locked by the locking rod, the needle piercing cap ignites and detonates the detonator, and the slider will not be affected by the thrust of the gunpowder when the needle piercing cap ignites, so that the detonator can be reliably detonated.

[0019] 3. The linked internal energy storage explosion device described in the present invention, which integrates safety, locking and ignition, has a simple working principle, high safety, high working reliability, strong parts processing technology, and can significantly reduce manufacturing costs.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 , the present invention provides the following technical solutions: a linkage type internal energy storage explosion device integrating safety, locking and ignition, comprising a shell 3, wherein the shell 3 is provided with an operating chamber 9 with a top opening;

[0030] The slider assembly 6 is provided in the operating chamber 9 and includes a slider 13 installed in the operating chamber 9. One end of the slider 13 is connected to a slider spring compression screw 21 via a slider spring 20. The slider 13 has a safety hole on one side and a locking hole 22 on the other side. The top of the slider 13 has a placement cavity in which a detonator 14 is installed. The bottom of the slider 13 has a transmission groove 23 in communication with the placement cavity.

[0031] The safety pin 7 is installed on one side of the operating chamber 9, with one end inserted into the safety hole and the other end passing through and extending out of the side wall of the housing 3, for fixing the position of the slider 13 in the operating chamber 9;

[0032] The internal energy storage ignition mechanism 4 and the locking mechanism 5 are installed on the other side of the operating chamber 9 and are linked to each other. The housing 3 is provided with a receiving chamber 1 that communicates with the operating chamber 9, and the internal energy storage ignition mechanism 4 is arranged in the receiving chamber 1;

[0033] The housing 3 is further provided with a second accommodating chamber communicating with the operating chamber 9, which is located on one side of the accommodating chamber 1, and the accommodating chamber 1 and the accommodating chamber 2 are communicated with each other through a limiting hole, and the locking mechanism 5 is arranged in the accommodating chamber 2;

[0034] The internal energy storage firing mechanism 4 includes a firing pin pressure screw 18 installed in the accommodating chamber 1. The firing pin pressure screw 18 is connected to the firing pin 16 via the firing pin spring 17. The end of the accommodating chamber 1 away from the firing pin 16 is connected to the operating chamber 9, and a needle-piercing primer 19 is provided at the communication point. A limiting hole is provided in the accommodating chamber 1 near the end of the firing pin 16, and a safety ball 15 is provided in the limiting hole to limit the end of the firing pin 16.

[0035] The locking mechanism 5 includes a locking pressure screw 12 installed in the accommodating chamber 2. The locking pressure screw 12 is connected to the locking rod 10 through the locking spring 11, and the end of the locking rod 10 extends into the operating chamber 9 close to the slider 13. One end of the locking rod 10 is located at the end of the limiting hole, limiting the safety ball 15 in the limiting hole, and the other end of the locking rod 10 is adapted to the locking hole 22.

[0036] Specifically, there are multiple locking threaded holes 8 distributed around the operating cavity 9, and a cover plate 1 is placed on the top of the shell 3. The cover plate 1 is installed on the top of the shell 3 through the locking bolts 2 and the locking threaded holes 8, which are used to cover the operating cavity 9 and better protect the structural components inside the shell 3.

[0037] Specifically, the locking rod 10 is composed of three cylindrical segments. The diameter of cylindrical segment one is adapted to the inner diameter of the locking hole 22, which limits the slider 13. The diameter of cylindrical segment two is larger than that of cylindrical segment one, and it is located at the end of the limiting hole, which limits the safety ball 15. The diameter of cylindrical segment three is smaller than the diameter of cylindrical segment one, and it is connected to the locking spring 11, ensuring that it is in contact with the locking spring 11 at all times.

[0038] Specifically, the firing pin 16 is provided with a chamfer near the safety ball 15 to avoid jamming during operation, so that the firing pin 16 can better push the safety ball 15 out of the limiting hole.

[0039] Specifically, the locking pressure screw 12, the firing pin pressure screw 18 and the slider spring pressure screw 21 are all flat screws, and their end faces are exposed on the side wall of the shell 3, ensuring that the internal energy storage ignition mechanism 4, the locking mechanism 5 and the slider assembly 6 can be inspected or maintained, and their structure is also better for their installation and assembly.

[0040] Specifically, the safety holes and the locking holes 22 on the slider 13 are staggered so that only one of the safety holes or the locking holes 22 can be restricted at all times in different states of the explosive device, thereby avoiding motion interference and causing detonation failure.

[0041] The working principle and usage process of the present invention are as follows: The linked internal energy storage explosive device, which integrates safety, locking, and ignition, is initially in an assembled state. When in this state, the safety pin 7 engages the slider 13, ensuring that the detonator 14 on the slider 13 is misaligned with the needle percussion cap 19 of the internal energy storage ignition mechanism 4. At the same time, the internal energy storage ignition mechanism 4 is constrained by the locking mechanism 5, making the needle percussion cap 19 unable to activate, thereby ensuring the safety of the ammunition before the safety is released.

[0042] When the ammunition needs to be fired and detonated, the safety pin 7 is pulled out of the housing 3, and the safety pin 7 cancels the constraint and fixation on the slider 13. The slider spring 20 elastically pushes the slider 13 to move in the operating chamber 9 until the locking hole 22 is aligned with the locking rod 10. At the same time, the transmission groove 23 is aligned with the communication between the accommodating chamber and the operating chamber 9, so that the locking spring 11 elastically pushes the locking rod 10 into the locking hole 22 to lock the slider 13. At the same time, since the locking rod 10 enters the locking hole 22, it cancels the restriction on the safety ball 15 in the limiting hole. The firing pin spring 17 pushes the firing pin 16 through the elastic force, so that the firing pin 16 pushes the safety ball 15 out of the limiting hole, and the firing pin 16 is pushed to poke the needle primer 19, so that it ignites. After the ignition, its energy is transmitted to the detonator 14 through the transmission groove 23, so that the detonator 14 is detonated, and because the slider 13 is restricted and locked by the locking rod 10, when the needle primer 19 ignites and detonates the detonator 14, the slider 13 will not be affected by the gunpowder thrust when the needle primer 19 ignites, so that the detonator 14 can be reliably detonated.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
