Technical Field

The utility model relates to an automatically-controlled door technical field specifically is a canned type intelligence people's bank of china emergency exit.

Background

The automatic door is as follows: the door opening control system comprises a control unit which can recognize the action of a person approaching the door (or authorize some entrance) as a door opening signal, opens the door through a driving system, automatically closes the door after the person leaves, and controls the opening and closing processes. The automatic door is widely applied to rapid bus stations, traffic light passing intersections and other important traffic places, and realizes highly intelligent, safe and rapid pedestrian access control. After the traditional automatic door works for a long time, under the influence of water vapor and dust, the function can lose efficacy, and the normal operation of traffic is hindered.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the technical problem that functions of a traditional automatic door are prone to failure after the traditional automatic door works for a long time is solved.

The utility model provides a sealed intelligent pedestrian safety door, which comprises a first movable door structure and a second movable door structure which have the same structure and are symmetrically arranged;

the first movable door structure comprises a door frame and door leaves, wherein a power mechanism is arranged at the upper end of the door frame, and the power mechanism drives the door leaves to move linearly through power transmission so as to realize the closing or separation of the two door leaves;

the protective cover is arranged at the upper end of the door frame, and the lower end of the protective cover is hermetically connected with the periphery of the upper end of the door frame.

When the pedestrian passes the safety door verification, the power mechanism drives the door leaf to move towards the door frame, the pedestrian can pass the safety door, and after the pedestrian passes the safety door, the power mechanism drives the door leaf to move towards the outside of the door frame, and the safety door is closed; so as to realize the automatic opening or closing of the automatic door; power unit sets up in the door frame upper end, and is covered inside the protection casing, and the protection casing forms confined space with door frame upper end periphery, makes the floating gate structure can not receive external environment's influence, all can normally realize its function.

Further, a linear guide rail is installed at the upper end of the door frame, and the upper end of the door leaf is fixedly connected with a sliding block in the linear guide rail;

the sliding block is transmitted through a synchronous belt arranged at the upper end of the door frame, and the synchronous belt is driven through the power mechanism.

Through power unit drive synchronous pulley, synchronous pulley drives the hold-in range operation to drive the slider and remove, linear guide has the precision height, removes stable characteristics, thereby makes the door leaf remove more stably, reliably.

Furthermore, a first roller group and a second roller group which have the same structure and are symmetrically arranged are installed on two sides of the lower end of the door frame, the first roller group comprises at least two rollers which are arranged in parallel, and the rollers are connected with the lower end of the door leaf in a rolling manner. The arrangement of the first roller set and the second roller set limits the lower end of the door leaf, and the phenomenon that the lower end of the door leaf shakes during the movement of the door leaf is avoided.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1 and 8, the utility model relates to a sealed intelligent pedestrian safety door, which comprises a first movable door structure 1 and a second movable door structure 2 which have the same structure and are symmetrically arranged;

as shown in fig. 2 and 3, the first movable door structure 1 includes a door frame 11 and a door leaf 12, the width of the door frame 11 is greater than the width of the door leaf 12, when the emergency exit is opened, the door leaf 12 can be completely hidden in the door frame 11, so that the emergency exit can achieve a complete passage for pedestrians to pass in and out;

the upper end of the door frame 11 is provided with a power mechanism 15, as shown in fig. 7, the power mechanism 15 comprises a direct current motor and a speed reducer, and the power output end of the speed reducer drives a synchronous belt to move through the synchronous belt;
