Embodiment Construction
[0023] The content of the present invention will be described below in conjunction with specific embodiments.
[0024] Such as figure 1 As shown, it is a structural schematic diagram of an existing rotatable access control device, including a fixed door frame 20, and a rotatable revolving door 10 used in conjunction with the door frame 20. The revolving door 10 rotates with Y as the central axis. A frame 21 is arranged on the side of the door frame 20 close to the passage, and the revolving door 10 cooperates with the frame 21 to form a "door" structure to open or close the middle passage. A suction part 100 is provided on one side of the edge of the revolving door 10, and a matching part 200 corresponding to the position of the suction part 100 is provided on the frame 21. Controllable electromagnetic coils are respectively arranged in the suction part 100 and the matching part 200. , the suction part 100 and the mating part 200 are suctioned together by magnetism.

The invention discloses a muffling long-life access control device comprising a fixedly-arranged door frame and a pivoted door which is used in cooperation with the door frame and is rotatable, wherein a side frame is arranged on the side, near a passage, of the door frame; an attraction part is arranged on one side of the edge of the pivoted door; a cooperation part of which the position corresponds to the position of the attraction part is arranged on the side frame; a groove is arranged around the attraction part; a protrusion part is arranged on the side frame; the position of the protrusion part corresponds to the position of the groove; a mold cavity is arranged between the protrusion part and the cooperation part on the side frame; the protrusion part is provided with a plurality ofsmall holes; and when the attraction part and the cooperation part are attracted together, the protrusion part enters the groove and a relatively-closed sealed space is formed inside the protrusion part. The muffling long-life access control device prolongs the service lives of the attraction part and the cooperation part; and in addition, the sound produced in the attraction process is basicallyinaudible to human ears. The structure is verified through practice, and is good in using effect, remarkable in technical effect and worthy of market promotion.
Description
