Embodiment Construction

[0010] Please refer to the attached figure 1 , 2 As shown, a center sleeve 10 is installed on the base plate 1, and the center sleeve 10 is fixed in the middle of the base plate 1. There is a ratchet mandrel 9 supported by a bearing in the center cover 10, and the front end of the ratchet mandrel 9 is equipped with a three-bar chassis 8 through a key. Three three bar rotating bracket heads 18 that are 120 degrees each other are housed on the bar chassis 8, and the metal bar 17 is connected on the three bar rotating bracket heads. The end is equipped with a central disc 27, which is fixedly connected with the ratchet 14 and the inner cam disc 12 through keys, vertical sleeves 13 and screws, and can rotate freely in the central sleeve 10, and is controlled by the ratchets on the left and right sides of the ratchet 14. The shift fork 7 restricts the forward or reverse rotation of the ratchet wheel 14, and at the same time restricts the forward or reverse rotation of the front th...

Abstract

The entrance guard device includes a central sleeve on the substrate, bearing supported ratchet wheel mandrel inside the sleeve; three-pole chassis with three-pole rotating carriage connected to metal rods; emergency opening unit mounted also on the chassis and capable of opening by the automatically falling rod in power failure; and central disc behind the ratchet wheel mandrel and connected viakey, vertical sleeve and screw to the ratchet wheel and internal cam for rotating freely inside the central sleeve. The ratchet wheel limited by the right and left shift forks rotates in right direction or inversely, and so does the front three poles, so that one pole of the three is made to stay in horizontal position or rotate to reach the aim of shutting down or opening the door.

Description

technical field [0001] The invention relates to a three-bar access control device for subways and public places where large flow of people passes through by swiping cards and pushing rods. Background technique [0002] The existing three-bar access control device does not have an emergency automatic opening device during a power failure, which is likely to cause safety accidents. Contents of the invention [0003] The object of the present invention is to provide a three-bar type access control device with low cost, simple structure, and automatic opening device for power failure emergency. It is equipped with a center sleeve on the bottom plate, the center sleeve is fixed in the middle of the bottom plate, and the center sleeve is supported by bearings. The ratchet mandrel, the front end of the ratchet mandrel is equipped with a three-bar chassis through a key, and three three-bar rotating bracket heads with a mutual angle of 120 degrees are installed on the three-bar cha...
