The benefits of the present utility model include:
1. The utility model utilizes high pressure gas in the pressurized gas containers mounted on a indoor ceiling or a wall as the power source to trigger the shooting mechanism, which releases the high pressure gas thus pushes out the bullets in the bullet holes of the shooting head; the bullets in turn pull out the net in a umbrella-like shape to cover and wrap the suspect, make the suspect unable to escape or struggle; therefore capture the suspect effectively, without injuring the police and people around.
2. The ceiling-mounted catcher is not only equipped with a shooting head but also another pressurized gas container, which can release high pressure gas to spray out stimulating substance and color paint from the small containers under it, causing the suspect unable to open eyes, difficult to breathe and subjects to a strong burning pain, thus the suspect fails temporarily to continue the crime, it wins the time for the police to arrive. Even if the suspect breaks the net and escapes, he will be noticed by people due to the significant color paint sprayed on him, providing valuable witness clues for solving the case later. At night, it can also spray fluorescent powder on the suspect, so that the suspect is exposed.
3. For a ceiling-mounted catcher, the shooting mechanism may be electro-magnetic valve triggered type or fuse resistor triggered type; for a wall-mounted catcher, the shooting mechanism may be electric fuse triggered type or hand-held spinning blade cut type, so that security personnel can take down the catcher from the wall and shoot at the suspect with it in hand; therefore, the shooting types of the utility model are various, and each type is simple in structure and easy to use.
4. The control unit of the utility model is designed at a concealed place that is easy to access; therefore, the utility model can trap the suspect quickly and effectively; the utility model can be connected to an internal alarm system in a police station or be controlled in a remote mode by a central monitoring system in financial enterprises.
5. Combined with existing CCTV monitoring systems of the banks, the utility model delivers great deterrent to criminals and can effectively prevent major crime (e.g., robbery, theft) in banks and jewelry stores.
wherein:
Hereunder, the utility model is further described in the embodiments, with reference to the attached drawings.
Said casing 1 is connected to the ceiling via a ball joints 3; the two pressurized gas containers 2, 2a are connected to the casing 1 via ball joints 3b, 3a respectively, so that the overall angle of casing 1 can be adjusted via the ball joints 3, and the angles of two pressurized gas containers can be adjusted via the ball joints 3a, 3b.
A slide track is mounted on the ceiling; the casing 1 can slide along the slide track or be fixed at an appropriate position.
A cap 10 is mounted under the shooting head 6 to prevent the bullets 8 and the net 9 from dropping.
Manometers 4, 4a are mounted at the orifices of the pressurized gas containers 2, 2a respectively to facilitate casual inspections for container pressure.
The shooting mechanisms mounted on the two pressurized gas containers 2, 2a shown in
The operating procedures of ceiling-mounted catcher with solenoid valve triggered shooting mechanism(s) are: turn on the concealed switch to power on the solenoid valve 5, which triggers the pressurized gas container 2 to release high pressure gas; pushed by the high pressure gas, the bullets 8 in the bullets holes 7 fly out and pull out the net 9 from the net storage pipe 7a in a umbrella-like shape to wrap the suspect. At the same time, the solenoid valve 5a on the pressurized gas container 2a is also powered on, so that the high pressure gas rushes through the T-joint 14 into the small container 12a containing stimulating substance 11a, the small container 12 containing color paint 11, and into the nozzles 13 under the small containers; under the pressure of the gas, the plugs on the nozzles are pushed out and the stimulating substance and the color paint are sprayed on the suspect, causing the suspect unable to continue the crime and leaving color marks on the suspect.
The operating procedures of a ceiling-mounted catcher with fuse resistor triggered shooting mechanism(s) are: switch on the switch so that the current flows through the leads and the riveted rings 17, 17a and fuses the wire resistor 18 winded on the fastening string 21; the high pressure gas in the pressurized gas container 2 pushes out the plug 20 and the pressing plate 19 and forces out the bullets, which in turn pull out the net. At the same time, the high pressure gas in the other pressurized gas container 2a also rushes out to force the small containers to spray stimulating substance and paint.
The indoor anti-riot catcher described in the utility model can also be mounted on a wall or at a corner. A wall-mounted catcher comprises a casing, pressurized gas containers, a shooting head, and shooting mechanisms; said casing is mounted on a wall or at a corner; the frames of said pressurized gas containers are mounted in the casing and are connected to the casing through boss and recess connection, which is detachable; the shooting head is mounted under the pressurized gas container; several bullet holes inclining outward at a certain angle are distributed along the periphery of the shooting head; one bullet in each bullet hole and the bullets are connected to the net in the net storage pipe of the shooting head through connecting strings; the shooting mechanisms are mounted at the orifices of the pressurized gas containers and may be online controlled to a central monitoring system or a CCTV monitoring system.
