Description

Technical Field

[0001] This utility model belongs to the field of security equipment technology, specifically relating to a dual-purpose tear gas and glass-breaking device. Background Technology

[0002] In daily life, single people may need to use self-defense tear gas spray or window-breaking escape equipment in emergency situations; or police officers may need to use tear gas spray or window breakers to subdue criminal suspects during an arrest.

[0003] To facilitate the carrying of tear gas spray and glass-breaking devices, a patent with authorization publication number CN217585531U discloses a portable glass-breaking tear gas device that combines tear gas spray and glass-breaking device into one, making it more portable. However, this patent uses piezoelectric ceramics to electrically ignite the propellant head separately, which has a certain degree of instability; most importantly, it is inconvenient to reuse.

[0004] In addition, tear gas spray is non-directional and there is a possibility of it missing its target. Utility Model Content

[0005] This invention provides a dual-purpose tear gas and glass-breaking device to solve the technical problems of poor directional tear gas spray in existing glass-breaking tear gas devices and the difficulty in reusing the piezoelectric ceramic ignition head.

[0006] This utility model includes: an upper handle;

[0007] The tear gas component is located inside the upper handle;

[0008] The lower handle is threadedly connected to the upper handle.

[0009] The glass-breaking component is located inside the lower handle;

[0010] The laser emitter is fixed parallel to the upper handle by a fixing member.

[0011] This invention utilizes a laser emitter as a pointing device for the tear gas component, ensuring the accuracy of the tear gas component's emission.

[0012] Further: the tear gas assembly includes:

[0013] A piston plate is located in the upper part of the inner cavity of the upper handle;

[0014] A fixing plate is located in the lower part of the inner cavity of the upper handle;

[0015] A tear gas spring is disposed between the piston plate and the fixed plate;

[0016] A nozzle is located at the top of the upper handle, and a spray hole is opened in the center of the nozzle. Tear gas is stored between the nozzle and the piston plate.

[0017] A trigger is located outside the upper handle. The head of the trigger extends into the inner cavity of the upper handle and is inserted into the compressed tear gas spring. The beneficial effect of this step is that by pressing the trigger, the front end of the trigger is disengaged from the compressed tear gas spring. The kinetic energy released by the tear gas spring will push the piston plate forward, squeezing and spraying out the tear gas liquid.

[0018] Furthermore, the upper handle is also provided with a protective cover, which is adapted to the trigger and the laser emitter. The beneficial effect of this step is that during the forward movement of the protective cover, the laser emitter can be pushed open and the trigger exposed, thus disarming the safety.

[0019] Further: the glass-breaking component includes:

[0020] A fixing sleeve is provided in the inner cavity of the lower handle;

[0021] A plug is located at the top of the fixed sleeve;

[0022] The firing pin is located inside the fixed sleeve;

[0023] A glass-breaking spring is provided between the plug and the striker;

[0024] A trigger sleeve is located on the outside of the fixed sleeve;

[0025] The striker is provided with a limiting point, the fixed sleeve is provided with a limiting groove corresponding to the limiting point, and the trigger sleeve is provided with a slanted groove corresponding to the limiting groove. The beneficial effect of this step is that by colliding with the trigger sleeve, the slanted groove of the trigger sleeve will push the striker out of the limiting groove of the fixed sleeve, and it will be ejected under the action of the glass breaking spring, thus impacting the glass.

[0026] Furthermore: a sealing gasket is provided between the nozzle and the upper handle, and one end of the sealing gasket extends into a nozzle plug;

[0027] The bottom of the lower handle is also equipped with a protective cap. The beneficial effects of this step are: the sealing gasket is used to seal the gap between the nozzle and the upper handle, and the nozzle plug can block the nozzle.

[0028] Furthermore, the surfaces of the lower handle and the protective cap are provided with knurling. The beneficial effect of this step is that the knurling increases friction and plays a role in preventing slippage.

[0029] The beneficial effects of this utility model are:

[0030] 1. This utility model not only integrates a tear gas component and a glass-breaking component, but also adds a directional laser emitter to the tear gas component, which can improve the accuracy of spraying tear gas liquid;

[0031] 2. Both the tear-inducing component and the glass-breaking component of this utility model are mechanical structures, which are easy to disassemble and reassemble, and can be reused repeatedly. Attached Figure Description

[0042] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0043] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0044] Examples of embodiments of this utility model Figures 1-6 As shown, the present invention provides a dual-purpose tear gas and glass-breaking device that can improve the accuracy of tear gas spraying, and is also easy to disassemble, reset, and reuse.

[0045] This utility model includes: an upper handle 1;

[0046] The tear gas component is located inside the upper handle 1;

[0047] The lower handle 2 is connected to the upper handle 1 by a thread;

[0048] The glass-breaking component is located inside the lower handle 2;

[0049] The laser emitter 4 is fixed parallel to the upper handle 1 by the fixing member 3.

[0050] This invention utilizes a laser emitter 4 as a pointing device for the tear gas component, which ensures the accuracy of the tear gas component's emission.

[0051] Based on the above technical solution, the tear gas component includes:

[0052] Piston plate 11 is located at the upper part of the inner cavity of the upper handle 1. A sealing ring is provided on the circumferential surface of piston plate 11, which is sealed to the inner cavity of the upper handle 1.

[0053] A fixing plate 12 is provided in the lower part of the inner cavity of the upper handle 1. The fixing plate 12 is connected to the inner cavity of the upper handle 1 by a thread. The bottom surface of the fixing plate 12 is provided with a groove or recess for rotation.

[0054] A tear gas spring 13 is disposed between the piston plate 11 and the fixed plate 12;

[0055] The nozzle 5 is also threaded onto the top of the upper handle 1. The nozzle 5 has a spray hole 51 in the center, and tear gas is stored between the nozzle 5 and the piston plate 11.

[0056] Trigger 14 is located outside the upper handle 1. The head of trigger 14 extends into the inner cavity of the upper handle 1 and inserts into the compressed tear gas spring 13. The head of trigger 14 can prevent the compressed tear gas spring 13 from releasing. By pressing trigger 14, the front end of trigger 14 is disengaged from the compressed tear gas spring 13. The kinetic energy released by the tear gas spring 13 will push the piston plate 11 forward. The tear gas liquid squeezed by the piston plate 11 will be sprayed out from the nozzle 51. After use, remove the nozzle 5, press the piston plate 11, and the tear gas spring 13 will be compressed. At this time, reinsert the head of trigger 14 into the tear gas spring 13 to prevent the tear gas spring 13 from opening. Then pour the tear gas liquid back onto the piston plate 11, screw on the nozzle 5, and the reset and reinstallation will be completed, ready for the next firing.

[0057] Based on the above technical solution, the upper handle 1 is also provided with a protective sleeve 7. The protective sleeve 7 is adapted to the trigger 14 and the laser emitter 4. The protective sleeve 7 can slide along the upper handle 1. When the protective sleeve 7 is below the upper handle 1, it can cover the trigger 14 and play a safety role to prevent the trigger 14 from being accidentally triggered. During the forward movement of the protective sleeve 7, the upper edge of the protective sleeve 7 corresponding to the laser emitter 4 can push open the switch 41 of the laser emitter 4, and the laser emitter 4 can emit a directional laser and expose the trigger 14 to release the safety.

[0058] Based on the above technical solution, the glass-breaking component includes:

[0059] The fixing sleeve 21 is threaded into the inner cavity of the lower handle 2;

[0060] The plug 22 is also threaded onto the top of the fixed sleeve 21;

[0061] The firing pin 23 is disposed inside the fixed sleeve 21, and the bottom of the fixed sleeve 21 is also provided with a through hole for the firing pin 23 to extend out.

[0062] A glass-breaking spring 24 is disposed between the plug 22 and the striker 23;

[0063] The trigger sleeve 25 is located on the outside of the fixed sleeve 21, and the bottom of the trigger sleeve 25 is also provided with a through hole for the protrusion of the firing pin 23.

[0064] The impact pin 23 is provided with a limiting point, and the fixing sleeve 21 is provided with a limiting groove corresponding to the limiting point. When the limiting point is locked in the groove on the side of the limiting groove, it can prevent the impact pin 23 from popping out. The trigger sleeve 25 is provided with a slanted groove corresponding to the limiting groove. When the bottom of the trigger sleeve 25 encounters a collision, the trigger sleeve 25 moves upward under force. At this time, the slanted groove will push the limiting point of the impact pin 23 out of the limiting groove of the fixing sleeve 21 and pop out under the action of the glass breaking spring 24, so as to hit the glass. When resetting, the limiting point can be locked back into the groove on the side of the limiting groove.

[0065] Based on the above technical solution, a sealing gasket 6 is also provided between the nozzle 5 and the upper handle 1. The sealing gasket 6 is used to seal the gap between the nozzle and the upper handle. One end of the sealing gasket 6 extends into a nozzle plug 61. The nozzle plug 61 blocks the nozzle 51 when the tear gas assembly is not in use to prevent tear gas leakage.

[0066] The bottom end of the lower handle 2 is also provided with a protective cap 26, which can prevent the trigger sleeve 25 from being accidentally triggered.

[0067] Based on the above technical solution, the surfaces of the lower handle 2 and the protective cap 26 are provided with knurled patterns. The knurling increases friction and provides an anti-slip function. In addition, the circumferential surface of the lower handle 2 can also be provided with a milled plane to increase the gripping force surface.

[0068] Because this utility model uses a mechanical structure to complete all functions, and all parts are connected by threads, it is easier to disassemble, reassemble, and reuse.
