Telescopic intelligent entrance guard

Abstract

The invention relates to a telescopic intelligent entrance guard which comprises an entrance guard device arranged between two side walls and recognition devices arranged on the inner side and the outer side of the entrance guard device respectively, the entrance guard device comprises a guide rail and a plurality of U-shaped door plates which are nested together step by step, the guide rail is laid on the ground between the two side walls, and a machine head is arranged on the guide rail in a sliding mode, in all the U-shaped door plates, the U-shaped door plate on the outermost layer is fixedly connected with the wall on one side, the U-shaped door plate on the innermost layer is fixedly connected with the machine head, the adjacent U-shaped door plates are connected in a sliding mode, and the end, close to the machine head, of any U-shaped door plate is provided with a rolling wheel matched with the guide rail. The telescopic intelligent access control is good in anti-creeping performance, can avoid the hidden danger of clamping in the opening and closing process, is suitable for being used on a large-span door wall, and occupies a small installation space; in the access control opening and closing process, each section of door plate is good in moving stability and smoothness, and is not easy to deform to influence use; and diversified identification modes are adopted, so that the use requirements of different users are met.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to a retractable intelligent access control. Background technique [0002] For some door walls with large spans, it is usually chosen to install scissor-type telescopic doors or plate-type translation doors. Although the scissor type telescopic door can save installation space, its anti-climbing performance is poor and there is a danger of jamming during use; while the plate-type sliding door has good anti-climbing performance and can avoid the hidden danger of jamming, but the long-span distance means Enough installation space should be reserved on the side of the exit door. [0003] Therefore, it is necessary to design an access control that combines the advantages of the above two types of doors to meet the needs of large-span doors and walls. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a retractable inte...
