Description

Technical Field

[0001] This invention relates to the field of tactical equipment technology, specifically to glass breakers. Background Technology

[0002] The hand-thrown glass-breaking vehicle barrier is a non-lethal tactical device designed for rapid breaching of vehicles, buildings, and other enclosed spaces. It combines highly efficient glass-breaking capabilities with rapid tear gas release, instantly shattering tempered glass and creating an irritating aerosol cloud to quickly disperse threatening individuals within the target area. It is suitable for highly sensitive law enforcement scenarios such as vehicle interception, counter-terrorism raids, and hostage rescue.

[0003] In existing technologies, tear gas is directly sprayed and released through a flue in hand-thrown glass-breaking ball valves. Because the temperature of the tear gas is high when it is released, it can easily cause injury to people. This release method is dangerous. Summary of the Invention

[0004] This invention provides a glass breaker to solve the problem of existing technologies where hand-thrown glass-breaking balls directly release tear gas, posing a certain danger due to the high temperature of the tear gas.

[0005] This invention provides a glass breaker, comprising a housing, a load release component, an activation component, and a safety component. The housing has an internal mounting cavity and several pointed heads on its exterior. The housing has mounting holes, slots, and several flues communicating with the interior. The load release component is disposed within the housing and is adapted to release smoke. The load release component is connected to the flues, and the smoke exits the flues along a curved path. The activation component is disposed within the housing, with one end located in the mounting hole. The activation component is signal-connected to the load release component. The safety component is inserted into the slot and movably connected to the activation component. The safety component has a locked state that restricts the movement of the activation component and an activated state that allows the movement of the activation component.

[0006] Beneficial effects: The present invention sets the flue in a bent shape, which can ensure that the high-temperature smoke emitted when the tear gas is burned in the load release component has a cooling process, avoiding the direct emission of high-temperature smoke and thus preventing injury to personnel.

[0007] In one alternative embodiment, the safety assembly includes a insert plate and a safety pin. The insert plate is inserted into a slot and is movably connected to the activation assembly. An opening is provided at one end of the insert plate away from the slot, and the safety pin is disposed in the opening.

[0008] Beneficial effects: The invention features a locking pin that can lock the button, preventing accidental triggering of the activation component. The safety pin on the insert plate prevents the pin from accidentally falling off, further improving the safety of the glass breaker.

[0009] In one alternative embodiment, the safety pin includes an insertion part and a limiting part. The insertion part is arrow-shaped, the limiting part is connected to the insertion part, and the insertion part passes through the opening.

[0010] Beneficial effects: The arrow-shaped insertion part of the present invention facilitates the installation of the safety pin in the opening, and the limiting part can prevent the safety pin from falling off.

[0011] In one alternative implementation, the safety assembly further includes a pull ring located outside the housing and connected to the insert plate.

[0012] Beneficial effects: The present invention provides a pull ring on the insert plate to facilitate the user's pulling operation.

[0013] In one alternative embodiment, the excitation assembly includes a button and an exciter. The button is movably disposed in a mounting hole, and the exciter is disposed within a housing. The top of the exciter abuts against the button, and the exciter is signal-connected to a load release assembly.

[0014] Beneficial effects: The present invention uses a button to trigger the exciter, which has the advantages of simple structure and convenient operation.

[0015] In one alternative implementation, the excitation assembly further includes a battery disposed within a housing and connected to the exciter.

[0016] In one alternative embodiment, the load release assembly includes a tear gas canister, at least one tear gas canister being disposed within the housing, the tear gas canister being connected to the activation assembly, and the release end of the tear gas canister being connected to the flue.

[0017] In one alternative implementation, two tear gas canisters are symmetrically arranged inside the housing, with their release ends positioned opposite to each other.

[0018] Beneficial effects: The present invention symmetrically arranges two tear gas canisters, which can achieve redundancy design to ensure smoke output. The opposite arrangement of the release ends of the two tear gas canisters can achieve multi-directional smoke output and improve the smoke output effect.

[0019] In one alternative embodiment, the glass breaker further includes a protective shell, two protective shells being detachably connected, forming a receiving cavity between the two protective shells, and the shell being detachably installed within the receiving cavity.

[0020] Beneficial effects: The present invention allows the shell to be detachably installed inside the protective shell, making it convenient for users to carry the glass breaker and preventing the sharp tip from piercing the user when carrying it.

[0021] In one alternative implementation, the two protective shells are hinged at one end and have a snap fastener at the other end. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0028] According to embodiments of the present invention, such as Figures 1 to 6As shown, a glass breaker is provided, including a housing 1, a load release component 2, an activation component 3, and a safety component 4. The housing 1 has an internal mounting cavity and several pointed heads 101 on its exterior. The housing 1 has mounting holes, slots, and several flues 102 communicating with the interior. The load release component 2 is disposed inside the housing 1 and is adapted to release smoke. The load release component 2 is connected to the flues 102, and the smoke exits the flues 102 along a bend. The activation component 3 is disposed inside the housing 1, with one end of the activation component 3 located in the mounting hole. The activation component 3 is signal-connected to the load release component 2. The safety component 4 is inserted into the slot and movably connected to the activation component 3. The safety component 4 has a locked state that restricts the movement of the activation component 3 and an activated state that allows the activation component 3 to move.

[0029] Specifically, such as Figures 1 to 3 As shown, the shape of the housing 1 is not specifically limited in this embodiment. For example, the housing 1 is spherical in this embodiment. The housing 1 has an internal mounting cavity and several pointed heads 101 on its outer wall. The pointed heads 101 can be used to break glass. The housing 1 has an activation component 3 inside, with one end of the activation component 3 installed in the mounting hole for easy operation by the user. The load release component 2 is installed inside the housing 1 and stores tear gas. The load release component 2 is connected to the activation component 3. Under the action of the activation component 3, the load release component 2 releases high-temperature tear gas smoke. The smoke is released into the external environment from inside the housing 1 through the flue 102 along a tortuous path. The tortuous path increases the flow of smoke inside the housing 1, reducing the temperature of the output smoke and preventing the high-temperature smoke from being directly sprayed into the external environment. The safety component 4 is inserted into the slot and detachably connected to the release component. When not in use, the safety component 4 restricts the movement of the activation component 3 and is locked to prevent accidental triggering of the activation component 3. When in use, removing the safety component 4 allows the activation component 3 to trigger the load release component 2.

[0030] In this embodiment, as Figure 1 and Figure 3 As shown, the housing 1 is provided with several smoke outlets, which are set vertically to the housing 1. The release end of the load release component 2 is set at an angle to the smoke outlet. The load release component 2 first releases the smoke into the receiving cavity, and then the smoke is output to the external environment from the smoke outlet. During the process of the smoke being output from the release end of the load release component 2 to the external environment, it flows through the bend and is output, which to a certain extent cools the smoke.

[0031] The present invention outputs the smoke through the flue 102 along a curved path, which can ensure that the high-temperature smoke emitted when the tear gas is burning in the load release component 2 has a cooling process, avoiding the direct emission of high-temperature smoke and thus preventing injury to personnel.

[0032] In one embodiment, such as Figures 1 to 4As shown, the safety component 4 includes a plug plate 401 and a safety pin 402. The plug plate 401 is inserted into the slot and is movably connected to the excitation component 3. An opening is provided at one end of the plug plate 401 away from the slot, and the safety pin 402 is disposed in the opening.

[0033] Specifically, in this embodiment, the insert plate 401 is rectangular and is horizontally inserted into the slot. One end of the insert plate 401 is inserted into the excitation assembly 3 to restrict the movement of the excitation assembly 3, and the other end extends out of the housing 1 for easy removal by the user. The end of the insert plate 401 away from the slot passes through the excitation assembly 3, and an opening is provided on the protruding part. A safety pin 402 is vertically inserted through the opening.

[0034] In this embodiment, the insert plate 401 is provided with two openings, and a safety pin 402 is provided in each opening. When not in use, the safety pin 402 can prevent the insert plate 401 from separating from the excitation component 3. When in use, the user pulls out the insert plate 401 with force. The insert plate 401 drives the safety pin 402 to move towards the slot. When the safety pin 402 abuts against the excitation component 3, the user continues to apply force. Under the action of external force, the insert plate 401 shears and breaks the safety pin 402 at the opening, thereby separating the insert plate 401 from the excitation component 3. At this time, the user can press the excitation component 3 to activate the load release component 2 to release tear gas smoke.

[0035] The present invention provides a locking pin to the button 301 to prevent accidental triggering of the trigger component 3, and a safety pin 402 on the insert plate 401 to prevent the pin from accidentally falling off, further improving the safety of the glass breaker.

[0036] In one embodiment, such as Figure 4 As shown, the safety pin 402 includes an insertion part 4021 and a limiting part 4022. The insertion part 4021 is arrow-shaped, and the limiting part 4022 is connected to the insertion part 4021. The insertion part 4021 passes through the opening.

[0037] Specifically, in this embodiment, the insertion part 4021 includes a pointed end and a connecting rod. Two wings are provided at one end of the connecting rod, forming an arrowhead-shaped structure. The tail end of the connecting rod is connected to the limiting part 4022. When the pointed end 101 is inserted into the opening, the two wings are compressed and deformed. After passing through the opening, the wings return to their original shape. The wings prevent the connecting rod from coming out of the opening. The limiting part 4022 is larger than the opening size, thus also limiting the connecting rod and preventing its tail from coming out of the opening. Under external force, the insertion plate 401 moves perpendicular to the connecting rod, and the shear force exerted by the opening on the connecting rod can break it.

[0038] The arrow-shaped insertion part 4021 of the present invention facilitates the installation of the safety pin 402 in the opening, and the limiting part 4022 can prevent the safety pin 402 from falling off.

[0039] In one embodiment, such as Figure 1 and Figure 3 As shown, the safety component 4 also includes a pull ring 403, which is located outside the housing 1 and is connected to the insert plate 401.

[0040] Specifically, in this embodiment, a pull ring 403 is provided at one end of the insert plate 401 located outside the housing 1.

[0041] The present invention provides a pull ring 403 on the insert plate 401 to facilitate the user's pulling operation.

[0042] In one embodiment, such as Figures 1 to 3 As shown, the excitation assembly 3 includes a button 301 and an exciter 302. The button 301 is movably disposed in the mounting hole, and the exciter 302 is disposed inside the housing 1. The top of the exciter 302 abuts against the button 301, and the exciter 302 is signal-connected to the load release assembly 2.

[0043] Specifically, in this embodiment, button 301 is cylindrical and is movably installed in the mounting hole. The top of button 301 matches the shape of housing 1. When button 301 is not pressed, the top of button 301 smoothly transitions to the housing. Actuator 302 is fixedly installed inside housing 1. The switch on top of actuator 302 abuts against the bottom of button 301. When the user presses button 301, button 301 triggers the switch to activate actuator 302. Actuator 302 sends a signal to load release assembly 2, which then releases tear gas upon receiving the signal.

[0044] The present invention triggers the exciter 302 via button 301, which has the advantages of simple structure and convenient operation.

[0045] In one embodiment, such as Figure 2 As shown, the excitation assembly 3 also includes a battery, which is disposed inside the housing 1 and connected to the exciter 302.

[0046] Specifically, in this embodiment, the battery is fixedly installed inside the housing 1 and is electrically connected to the exciter 302 to supply power to the exciter 302 to ignite the load release component 2, thereby releasing tear gas smoke.

[0047] In one embodiment, such as Figure 2 and Figure 3 As shown, the load release assembly 2 includes a tear gas canister 201. At least one tear gas canister 201 is disposed inside the housing 1. The tear gas canister 201 is connected to the activation assembly 3. The release end of the tear gas canister 201 is connected to the flue 102.

[0048] Specifically, in this embodiment, the number of tear gas canisters 201 is not specifically limited. For example, in this embodiment, there are two tear gas canisters 201, which are symmetrically arranged on both sides of the button 301.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, two tear gas canisters 201 are symmetrically arranged inside the housing 1, and the release ends of the two tear gas canisters 201 are arranged opposite to each other.

[0050] Specifically, in this embodiment, the two tear gas canisters 201 are vertically arranged with opposite smoke release directions. A smoke channel runs between the two canisters 201, and the smoke outlets are connected to the inner side of the smoke channel. In this embodiment, four smoke outlets are provided, symmetrically located on both sides of the smoke channel, with two outlets on each side. When smoke is released, it originates from the top of the tear gas canister 201 and enters the smoke channel in the middle of the housing 1. The smoke then exits through the smoke outlets to the outside of the housing 1.

[0051] The present invention symmetrically arranges two tear gas canisters 201, which can achieve redundancy design to ensure smoke output. The release ends of the two tear gas canisters 201 are set opposite to each other to achieve multi-directional smoke output and improve the smoke output effect.

[0052] In one embodiment, such as Figure 5 and Figure 6 As shown, the glass breaker also includes a protective shell 5. The two protective shells 5 are detachably connected, and a receiving cavity is formed between the two protective shells 5. The shell 1 is detachably installed in the receiving cavity.

[0053] Specifically, in this embodiment, the outer wall of the protective shell 5 has a polyhedral structure, and the inner wall matches the shape of the shell 1. When the two protective shells 5 are fastened together, a receiving cavity matching the shape of the shell 1 is formed inside, and the shell 1 is disassembled and placed inside the protective shell 5.

[0054] The present invention allows the housing 1 to be detachably installed inside the protective housing 5, making it convenient for users to carry the glass breaker and preventing the pointed tip 101 from piercing the user when carrying it.

[0055] In one embodiment, such as Figure 5 and Figure 6 As shown, the two protective shells 5 are hinged at one end and have a buckle 501 at the other end.

[0056] Specifically, in this embodiment, one end of the protective shell 5 is connected by a hinge 502, and the other end is provided with a buckle 501. The buckle 501 can lock and open the two protective shells. When locked, the shell 1 can be stably placed inside the protective shell 5 to prevent the sharp head 101 from piercing the wearer. When opened, the wearer can take the shell 1 out of the protective shell 5 for use.

[0057] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
