Quickly-opened embrasure

Abstract

The invention discloses a quickly-opened embrasure. The quickly-opened embrasure comprises a bullet-proof steel plate provided with an opening hole and an embrasure body; a guide limiting shaft sleeveis fixedly welded inside the opening hole; the inside of the guide limiting shaft sleeve is movably connected with a rotating shaft; the rotating shaft is connected with one side of a connecting partin a welding manner after extending out of the guide limiting shaft sleeve; the other side of the connecting part is connected with a movable baffle; the outer side of the bullet-proof steel plate isfixedly provided with an external limiting groove corresponding to the embrasure body in a welding manner; the inner side of the guide limiting shaft sleeve is fixedly provided with a handle support;a handle is arranged on the handle support; the handle comprises an eccentric cam and a hand shank; one end of the rotating shaft is hinged with the eccentric cam after protruding out of the handle support; the eccentric cam is provided with an extending limiting surface and a closing limiting surface; the hand shank is pulled to make the movable baffle extend out of the external limiting groovewhen the extending limiting surface of the eccentric cam makes contact with the handle support; and the hand shank is also pulled to make the movable baffle retract into the external limiting groove when the closing limiting surface of the eccentric cam makes contact with the handle support. The quickly-opened embrasure is safe, reliable, and quick and convenient to open.

Description

technical field [0001] The invention relates to the technical field of explosion-proof equipment for special vehicles, in particular to a quick-opening shooting hole. Background technique [0002] In recent years, the domestic public security situation has become increasingly severe, the crime rate has risen sharply, terrorist forces have gradually risen, and drug-making and drug-trafficking gangs have become increasingly rampant. The severe social security situation has put forward higher requirements for the rapid handling capabilities of our public security and armed police; In order to quickly and effectively respond to emergencies, riot-proof armored vehicles have gradually become a new field. The firing hole is the window for the anti-riot vehicle to handle extreme events, and its reliability and flexibility play a vital role in the entire defense capability. [0003] But now there are mainly two types of shooting holes in China: the first one is the shooting hole wit...

Problems solved by technology

[0003] But now there are mainly two types of shooting holes in China: the first one is the shooting hole with tension spring (the spring is under tension in the closed state to keep the seal reliable), and the spring is compressed by pushing the handle to make the protective panel exceed the limit slot, so that it can be opened. Turn the handle to open the protective cover, but it has the following defects: (1) In order to save space, the handle is small, and it is extremely inconvenient to push and pull; (2) There is no limit when it is pushed out, and there is no limit when it is turned, and it can be rotated at will, or even closed forcibly , extremely unsafe; (3) When closing, a safety pin needs to be inserted to ensure that the outside cannot be opened, but the operation is cumbersome. When opening, the safety pin needs to be removed first, which cannot meet the purpose of quick strike

The second commonly used is the mechanical flip-out shooting hole. The inside is locked by the baffle. Although the lock is reliable and easy to open, it cannot be closed quickly from the inside when terrorists use poisonous gas, and there is a certain risk.
