[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below 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 creative work are within the scope of protection of the present invention.

[0030] This embodiment provides a pressure relief and splash prevention device suitable for breaking door locks, such as Figure 1 and Figure 2 As shown, the pressure relief and splash prevention device includes a launcher and a circular pressure relief and splash prevention mechanism coaxially connected to the launcher mouth.

[0031] like Figure 3 and Figure 4 As shown, the side wall of the pressure relief and splash prevention mechanism is provided with a plurality of pairs of air relief grooves along the axial direction, each pair of air relief grooves is symmetrical along the central axis, and two axially adjacent air relief grooves are spaced apart by a first preset distance to ensure the mechanical strength of the pressure relief and splash prevention mechanism.

[0032] This embodiment provides a pressure relief and splash prevention mechanism with an air relief groove at the mouth of the launcher. On the one hand, it is used to discharge the gunpowder gas in the launcher chamber to prevent the launcher mouth from being blocked by metal powder and causing the chamber to explode. On the other hand, it gathers the metal powder and makes full use of the broken metal powder to damage the door lock. On the other hand, the splashing metal powder is shielded by the pressure relief and splash prevention mechanism to prevent harm to the staff.

[0033] In addition, the air relief grooves of the present invention are arranged in pairs, and each pair of air relief grooves is symmetrical along the central axis, that is, two symmetrical air relief grooves are arranged on the same cross-section of the circular pressure relief and splash-proof mechanism, which can ensure that the pressure relief and splash-proof mechanism is subjected to uniform force during the air relief process, thereby preventing the pressure relief and splash-proof mechanism from falling off the launcher or causing the launcher to shake.

[0034] In some embodiments, the area on the side wall of the pressure relief and splash prevention mechanism where no air relief groove is provided is provided with weight reduction holes arranged in an array to reduce the weight of the pressure relief and splash prevention mechanism itself, and the weight reduction holes do not penetrate the side wall of the pressure relief and splash prevention mechanism.

[0035] In some embodiments, a second preset distance between the lightening hole and the outer surface of the pressure relief and splash prevention mechanism is equal to a third preset distance between the lightening hole and the inner surface of the pressure relief and splash prevention mechanism.

[0036] In some embodiments, a spacing distance between two axially adjacent lightening holes is equal to a spacing distance between two radially adjacent lightening holes.

[0037] In some embodiments, Figure 6 As shown, one end of the pressure relief and splash prevention mechanism is arranged on the periphery of the launcher mouth and is locked by a screw to prevent the pressure relief and splash prevention mechanism from falling off from the launcher mouth.

[0038] In some embodiments, one end of the pressure relief and splash prevention mechanism is sleeved on the outer periphery of the launcher mouth through the inner cavity circular surface and the step end surface.

[0039] In some embodiments, Figure 5 As shown, a clamp structure is provided at one end of the pressure relief and splash prevention mechanism connected to the mouth of the emitter.

[0040] In some embodiments, the clamp structure includes at least one threaded hole and a matching stepped hole.

[0041] Preferably, the clamp structure comprises a plurality of threaded holes and matching stepped holes, and the plurality of threaded holes are symmetrical around the central axis.

[0042] Preferably, the number of the threaded holes and the number of the stepped holes are both two.

[0043] In some embodiments, a gap is provided between the threaded hole and the stepped hole to further lock the pressure relief and splash prevention mechanism to the launcher to prevent loosening.

[0044] In some embodiments, the pressure relief and splash prevention mechanism is formed in one piece by laser melting 3D printing of titanium alloy to meet the needs of rapid production.

[0045] In some embodiments, the launcher is a gun-shaped launcher.

[0046] In some embodiments, Figure 1 and Figure 2 As shown, the pressure relief and splash prevention device suitable for breaking door locks also includes a destruction mechanism.

[0047] Specifically, the damaging mechanism is a lock-breaking bullet, and the interior of the lock-breaking bullet is filled with metal powder.

[0048] The working process and principle of the pressure relief and splash prevention device for breaking door locks of the present invention are as follows:

[0049] like Figure 7 As shown, a launcher 1 equipped with a pressure relief and splash-proof mechanism 2 is brought close to a door lock, and the launcher 1 launches a lock-breaking bullet 4, in which a metal powder body 41 directly strikes and damages the door lock. On the one hand, the pressure relief and splash-proof mechanism 2 can gather the metal powder body 41 and make full use of the broken metal powder to damage the door lock; on the other hand, the high-temperature and high-pressure gas generated during the launch of the lock-breaking bullet 4 is discharged through the gas relief groove of the pressure relief and splash-proof mechanism 2, to prevent the metal powder 41 from colliding with the target (such as a door lock) and then blocking the mouth of the launcher 1, so that the high-temperature and high-pressure gas cannot be discharged and causes a bursting accident; on the other hand, the splashing metal powder 41 is shielded by the pressure relief and splash-proof mechanism 2 to prevent harm to the staff.

[0050] After use, the pressure relief and splash prevention mechanism 2 can be disassembled from the launcher 1 to clean the residue.

[0051] In summary, the solution proposed by the present invention has the following technical effects:

[0052] The invention provides a pressure relief and splash prevention mechanism with a gas relief groove at the mouth of the launcher to discharge gunpowder gas in the launcher chamber, thereby preventing the launcher mouth from being blocked by metal powder and causing the chamber to explode.

[0053] In addition, the side wall of the pressure relief and splash prevention mechanism of the present invention is provided with weight-reducing holes arranged in an array to reduce the weight of the pressure relief and splash prevention mechanism itself.

[0054] In addition, one end of the pressure relief and splash prevention mechanism of the present invention is set as a clamp structure, which is convenient for locking the pressure relief and splash prevention mechanism and the launcher, and the clamp structure is suitable for launchers of different calibers and has good compatibility and adaptability.

In order to make the description concise, all possible combinations of the technical features in the above embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above embodiments only express several implementation methods of the present application, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, several variations and improvements can be made, which all belong to the scope of protection of the present application.
