Financial anti-theft safety door of double-door-type structure

Abstract

The invention belongs to a safety door in the field of finance, and particularly relates to a financial anti-theft safety door of a double-door-type structure. The financial anti-theft safety door ischaracterized in that a first door body (1) and a second door body (2) are arranged at the front end and the rear end of a bridge passage (3) correspondingly; the bridge passage (3) is internally provided with first switches (19 and K1), conversion switches (15 and K0) and a barrier plate (11) which is transversely and rotatably connected; a rotating shaft motor (10) and a barrier plate spring (18) are arranged on a shaft rod (9) of the barrier plate (11), and a second electromagnetic lock (7) is arranged on the second door body (2); and a resistor (R1) of the rotating shaft motor and a resistor (R2) of the second electromagnetic lock are connected in parallel and then connected with the conversion switches (15 and K0) arranged on a primary circuit in series, wherein the conversion switches can be mutually switched between branch circuits of the resistor (R1) of the rotating shaft motor and the resistor (R2) of the second electromagnetic lock. By additionally arranging a barrier mechanism and the second door body in the bridge passage, anti-trailing crossed opening and closing are achieved, and the risk of trailing of the first door body is reduced.

Description

technical field [0001] The invention belongs to a safety door in the financial field, and in particular relates to a financial anti-theft safety door with a double-door structure. Background technique [0002] There are usually two security door passages installed between the hall and the counter in the bank to ensure that bank personnel will not enter and exit suddenly from robbers. CN200420055275.7 discloses an anti-tailgating linkage safety door, which is to watch the first door, send a signal to the control device through a sensor, after the first door is closed, use a key to open the second door. But there are two problems in it, the first cannot guarantee that the person who enters the first door is a person, and the second needs to use the key to open the door every time, which reduces the speed of personnel passing. The shorter the time it takes for the user to enter the first door, the less the risk of being tailed. In the prior art, the user enters the first door ...
