Description

It is alert with throwing tear-gas bomb from locking-type aerosol hand

Technical Field

The utility model relates to a tear-gas shells field especially relates to a tear-gas shells is thrown to alert aerosol hand with self-locking function.

Background

The tear-gas shells are also called lachrymatory gas and lachrymatory explosion-proof shells, and belong to nonfatal police or weapon ammunition. The traditional tear-gas shells are all of combustion nature, and are filled with magnesium, aluminum, sodium nitrate, barium nitrate and other substances. After detonation, the magnesium is rapidly combusted in the air to emit dazzling white light containing ultraviolet rays, and simultaneously, the nitrate is decomposed by emitting heat, and the generated oxygen further promotes the combustion of the magnesium and the aluminum; the tear-gas bomb is filled with volatile liquid bromine which can stimulate the sensitive parts of human body, such as mucous membranes of organs like eyes and noses, and stimulate the tear to flow downwards. Sometimes it is also charged with the toxicant, siemens (CS agent), which causes profuse tearing, severe coughing, and sneezing, which is intolerable and can lead to death. Taking the tear-gas shells RS97-2 of domestic shaping equipment as an example, the tear-gas shells react with combustible agents through oxidants in main charge, and a large amount of heat and gas generated by the reaction sublimate and evaporate irritant aerosol tear-gas, so that irritant aerosol is sprayed out from smoke holes to act on a living target. The structure of the device mainly comprises an ignition mechanism, a safety device, a projectile body and a main charge 4. The main function of the ignition mechanism is to ignite the ignition tablet after 0.7-1.5 seconds of delay, thereby igniting the main charge. The firing mechanism consists of a firing seat, a firing pin spring and a needle-prick delay igniting tube. The safety device controls the percussion and prevents accidental impact ignition; consists of a safety handle, a safety pin and a pull ring. The projectile body is a main part for containing medicament (main charge) and connecting all parts and consists of a projectile barrel and a connecting seat. The connecting seat is used for connecting the ignition mechanism and the bomb tube into a whole, 4 oblique smoke holes are formed in the circumferential surface of the connecting seat and used for discharging lacrimator smoke (irritant aerosol) generated by atomization of the main charge, and the smoke holes are sealed by hot melt sealant at ordinary times. The cartridge is made of aluminum and is used for containing lacrimatory agents. A round smoke hole is arranged at the center of the bottom (the end opposite to the connecting seat) of the bomb tube and used for discharging lacrimator smoke.

The prior technical scheme has a plurality of defects and hidden dangers in inconvenient and numerous safety aspects in actual combat.

The traditional tear-gas shells triggered by the fire powder bin or combustion have the case that inflammable objects in a room are on fire due to the fact that the tear-gas shells based on the throwing combustion principle are thrown for many times, and meanwhile, the cases that a thrower and a thrown person are bruised, scalded and killed by the traditional tear-gas shells due to misoperation or other reasons occur for many times.

Structurally, as the traditional tear-gas shells need to be added with complex structures such as smoke agent or gunpowder, ignition agent, firing seat, firing pin and the like, the traditional tear-gas shells which need to be portable cannot be added with excessive tear agent in the shells, usually, the tear-gas shells with the diameter of 38MM can be added with about 10 g of tear agent, and the tear-gas agent concentration and the continuous smoke amount of the traditional tear-gas shells are not ideal.

In addition, traditional tear-gas shells all possess insurance shell fragment and insurance pull ring. The user is in-service use, at first need one hand tightly to hold the safety handle, the other hand need rotate insurance pull ring (safety catch) and make strength pull-out simultaneously, the tear-gas shells is in the preparation state this moment, because the user is still holding the safety handle tightly, so the tear-gas shells can not percussion smoking, the user need preserve the insurance pull ring usually and give up after the task so that the producer recycle, in this state, when the user throws out the tear-gas shells, shell fragment in the safety handle releases in the twinkling of an eye, lead to traditional tear-gas shells to ignite ignition device, and ignite tear-gas agent release tear-gas smog. With such safety handles with spring release, it is also common at home and abroad to have a spring escape from the housing to hurt the user or innocent people. In addition, in a vanishing battlefield or an anti-terrorism and anti-riot environment, personal safety of a user is concerned every minute and every second, the existing tear-gas shells firstly need to be used by both hands of the user, which means that the user needs to temporarily put down weapons or protective equipment (such as an explosion-proof shield) in the hands, and if an emergency happens at the moment, the user cannot rapidly respond to kill enemies or protect the user.

Detailed Description

The self-locking aerosol hand-throwing tear-gas bomb for police of the utility model is further explained by combining the attached drawings.

A self-locking aerosol hand-throwing tear-gas bomb for police mainly comprises a disposable locking cover 1, an aerosol valve 2 and a tank body 3. Optionally, the tear-gas bomb may be provided with accessories such as a bottle cap and a PVC hose, which are conventional in the art and are not illustrated in the present example.

Specifically, fig. 1 is a schematic cross-sectional structure diagram of the aerosol valve 2. Referring to fig. 1-2 and 6 (for clarity, functional components such as valve stem 23 are relatively large in size, line portions such as can 3 are relatively short; length ratio of can 3, length of gentle portion of valve cup 21 are much larger than the scale shown in the figure) in the actual product, an exemplary aerosol valve 2 used in the present invention includes a valve cup 21, a valve housing 22, a valve stem 23, an inner gasket 24, an outer gasket 25, a spring 26 and a liquid tube 27.

The outer edge of the valve cup 21 is sealingly connected to the mouth of the can body 3 by an outer gasket 25 (see fig. 2 and 6), and the inner edge is sealingly connected to the valve housing 22 and the valve stem 23 by an inner gasket 24. The valve housing 22 houses one end of a stem 23 and a spring 26, the stem 23 extending from the valve housing 22, through the inner gasket 24, and out of the valve cup 21. The valve rod 23 has a hollow main body and a nozzle 30 at the top end for spraying aerosol; the bottom end is closed (suitably thickened to ensure tightness, as shown in fig. 1, and provided with a spring groove to ensure a stable abutment) against the spring 26, the bottom side (left side as shown in fig. 1) having a lateral hole for the entry of aerosol fluid. A spring 26, one end of which abuts against the bottom end of the stem 23 and the other end of which abuts against the wall of the chamber 22, is provided to hold the stem 23 in a closed position (storage state) in which the lateral aperture of the stem 23 is located at the internal gasket 24, ensuring a fluid-tight seal in the tank; a liquid pipe 27 extends from the lower end opening of the valve chamber 22 into the can 3, and supplies the objects to be sprayed (aerosol fluid — propellant and tear agent) from the can 3 to the valve chamber 22.

Further, fig. 3 is a schematic perspective design view of the disposable locking cap 1, which is an injection molded one-piece plastic structure with plastic deformation characteristics, and is the most preferred design view. On the contrary, fig. 4 is a schematic top view, fig. 5 is a schematic central sectional view, focusing on the functional schematic, and not showing all the design details in the design drawing of fig. 3 (for example, the peripheral protection vertical surface of the pressing locking part 12 in fig. 3 is not shown in fig. 5), and the disposable locking lid of the present example is a lid structure capable of realizing disposable locking, which has the functional details of fig. 4 and 5.

Referring specifically to fig. 3-6, the disposable locking cap 1 is divided into three parts, a base 11, a push locking part 12 and a spray opening 13, which are concentrically arranged (also concentrically arranged with the can section/nozzle). The base 11 is substantially in the shape of a hollow cylindrical ring, and the bottom side thereof is provided with an inward bottom flange 111 for forming a snap connection with the mouth of the can body 3; at the upper edge, there is also an inwardly projecting detent flange 112.

The main body of the pressing locking part 12 is a circular deformable plastic sheet (a reinforced edge may have an elevation as shown in fig. 3); one end of the pressing part extends from the base 11 (the lower end of the pressing part is connected as shown in fig. 4, and can be a circular piece extending from a vertical surface of the top surface of the base 11, or can be a circular piece extending obliquely upwards), the opposite end of the pressing part is a sector-shaped pressing part 121, and the upper surface of the pressing part 121 is preferably provided with a friction strip to increase friction force. The locking protrusion 122 is located under the pressing portion 121, and is disposed corresponding to the locking flange 112 for locking; to achieve locking, the locking projection 122 and the detent flange 112 preferably each have a slope that is inclined toward one another so that they cannot be reset easily (by deformation) past one another.

The injection port 13 extends upward from the middle of the pressing locking portion 12; of course, depending on the height of the mating nozzle 30, it may also extend downwardly. The injection port 13 is open at the center.

In a normal state (storage state), the circular plastic sheet of the locking part 12 is slightly higher than the upper surface of the base 11, and at the time, the injection port 13 does not press the nozzle 30 down, so that the nozzle is kept in a closed position under the action of spring force and high-pressure air; when the pressing part 121 is pressed down by an external force, the locking protrusion 122 is locked after being deformed downward beyond the catching flange 112, and at this time, the injection port 13 presses down the nozzle 30 to the injection position (the lower end opening of the valve stem 23 is exposed to the valve chamber 22, so that the high-pressure mixture in the tank can be injected along the valve stem 23).

The tank body 3 is internally mixed by propellant and lacrimator, and the propellant is compressed gas.

The valve rod 23 can also be reversely refilled with contents, and after the lacrimatory agent is filled into the tank body 3, the propellant (compressed gas) is pumped into the tank, and at the moment, the lacrimatory agent and the propellant (compressed gas) are contained in the tank.

As another possible solution, the present invention provides a self-locking aerosol hand-throwing tear-gas bomb for police, which can be obtained by disposing a vacuum bag (the liquid tube 27 can be omitted) in the can body 3 (this solution is not shown in the drawings), and connecting the vacuum bag to the valve chamber 22. At this time, compressed air is filled between the tank body 3 and the vacuum bag, lacrimatory agent is filled in the vacuum bag, and other structures are the same as the above preferred scheme.

In this scheme, the vacuum bag is four layers of vacuum bags.

The specific working principle is as follows: after the aerosol valve is pressed, the propellant (high-pressure gas) is discharged out of the bottle body, the vacuum bag filled with the lacrimatory agent (the capsicum agent, the CN agent or the CS agent are not limited) is extruded by utilizing the pressure principle (the propellant directly propels the lacrimatory agent to be atomized and sprayed in the scheme 1), and the lacrimatory agent is promoted to be sprayed out. The back is erupted to the lacrimatory agent, at first can be through the aerial fog valve, and the principle that the aerial fog valve made the lacrimatory agent to disperse into tiny dropping liquid through high-speed gas makes the lacrimatory agent atomizing turn into aerosol to the jar body is erupted to pressure through propellant (gas), diffuses in the atmosphere.

In the in-service use, the user only needs the one-hand to press disposable locking lid to the lock-out state, and the nozzle is in spraying the position this moment, and inside and outside intercommunication state, lacrimator just begin to spray the atomizing, and the user throws novel tear-gas shells to the target direction this moment can. The tear-gas shells can continuously atomize and spray the lacrimatory agent at the moment when the motion trail and the landing, the lacrimatory agent is converted into aerosol after being atomized, and the propellant has pressure intensity, so that the lacrimatory agent can be rapidly diffused in the atmosphere, and rapid and effective lacrimation is caused to target crowds. Even target crowd someone tries to pick up novel tear-gas shells and tries to throw back to user's side, because of tear-gas shells have shower nozzle locking device, tear-gas shells continuously sprays (until the lacrimator has been spouted), the people who tries to pick up tear-gas shells also can give up to pick up the action because of not receiving the lacrimator of tear-gas shells.

Meanwhile, the novel tear bomb can also utilize a PVC hose to connect the nozzle part and the door slot. Similar to the narrow space of prisons, in case of a travel group event, a disposal person is usually inconvenient to open for throwing a traditional tear-gas shells in a short time, because the people may rush out of a door to cause injury to the disposal person; after novel tear-gas shells utilized PVC hose connection shower nozzle and crack, the user only need press the novel tear-gas shells of locking, and the tear-gas just can be shed to indoor volatilizing through the PVC hose, provides more convenience for dealing with next.

After the novel tear-gas shells are used up, the user can send the intact tear-gas shells of the bottle back to a production factory. The production factory only needs to replace or repeatedly fill the vacuum bag in the bomb (bottle) body with new lacrimatory agent, fill the propellant (gas) again and replace the disposable locking nozzle, so that the cost of a user is further reduced.

In transportation and storage process, can not cause the threat of deflagration, be different from traditional initiating explosive device tear-gas shells, this kind of neotype tear-gas shells because inclusion stability is higher relatively, deflagration not, can be in the shade normal atmospheric temperature store can to ordinary commodity circulation alright with transporting, the at utmost has reduced transportation and storage cost.
