Transportable access control device for construction site
The invention discloses a transportable access control device for a construction site. The device comprises a main body and an auxiliary body, the auxiliary body is separated from the main body; a connecting groove with a rightward opening is formed in the right side wall of the auxiliary body; a movable groove with a leftward opening is formed in the left side wall of the main body; a lifting groove with a leftward opening is formed in the right side wall of the movable groove; and screw shafts extending downwards are rotationally installed on the upper wall and the lower wall of the liftinggroove. The screw shafts are in threaded connection with lifting blocks with opposite threads in the lifting groove in an up-and-down symmetrical manner; the lifting blocks are in sliding fit with theinner walls of the lifting grooves; and the lifting blocks at the upper and lower sides extend into the main body and are in rotation connection with hinge compression rods. The device has the advantages that the structure is simple, the operation is convenient, the function change of the device is controlled through the control turntable, the rotating rod is driven through the connecting shaft to fix the main body; and the movable block and the main body can be separated.
本发明公开了一种建筑工地用可搬运门禁装置，包括主机体和副机体，所述副机体与所述主机体分离，所述副机体右侧壁设有开口向右的连接槽，所述主机体左侧壁设有开口向左的活动槽，所述活动槽右侧壁上设有开口向左的升降槽，所述升降槽上下壁转动安装有向下延伸的螺杆轴，所述螺杆轴于所述升降槽内上下对称螺纹连接有螺纹相反的升降块，所述升降块和所述升降槽内壁滑动配合，上下侧所述升降块伸入所述主机体转动连接有铰接压缩杆，本装置结构简单，操作方便，通过控制转盘控制装置的功能变化，从通过衔接轴带动转杆来固定主机体，同时可使活动块和主机体分离。
