As shown in Figures 2 to 3b, the shaft link 100 produces a planar shape as shown in Figure 3a processing a metallic plate material (eg, press working, cutting, punching or perforation). As shown in Figure 3a, the shaft link 100, the first plate 150, the bent portion 140 and the second plate 160 are integrally formed. At both ends of the shaft link 100, the second shaft connection parts 120 and 125 are formed through, respectively, and the first shaft connection parts 110 and 115 are formed through the vicinity thereof.

In addition, the slot 130 is formed to pass through the first shaft connecting portions 110 and 115 and the bent portion 140 . The slot 130 may be elastically narrowed by tightening the bolt 180 assembled to the outside of the bent portion 140 .

The second shaft connecting portions 120 and 125 are positioned on the same center line so that the second shaft 200 can pass through at the same time.

Construction of rotating structures with axial links

Hereinafter, the configuration of the rotation structure will be described in detail with reference to the accompanying drawings. 4 is a partial perspective view of the rotation structure to which the shaft link shown in FIG. 2 is applied, and FIG. 5 is a perspective view illustrating the rotation structure illustrated in FIG. 4 in an open state. 4 and 5 , the driving shaft of the motor 5 becomes the first shaft 190 and is inserted into the first shaft connection part 110 . In addition, by tightening the bolt 180 and the nut mounted to the bent portion 140 , the gap between the slots 130 is reduced so that the first shaft 190 is press-fitted into the first shaft connection portion 110 .

One end of the "L"-shaped first link 210 is rotatably connected to the second shaft connection part 120 , and the other end is connected to the second link 220 .

The second link 220 has the configuration of the integral axial link 100 shown in FIG. That is, one end of the second link 220 is connected to the first link 210 , and the other end is fitted to the rotation center shaft 230 . The rotation center shaft 230 is fixed to the second link 220 by a bolt and a nut. The second link 220 is fixed to one end of the rotation center shaft 230 and the stopper 250 is fixed to the other end so as to be integrally rotatable.

The third link 260 has the same structure as the axial link 100 and the second link 220 . One end of the third link 260 is integrally coupled to the central axis of rotation 230 , and the other end is connected to a spring 240 . The spring 240 generates a torque to return to the central axis of rotation 230 .

The stopper 250 is fixed to the other end of the rotation center shaft 230 , and a blocking rod of the parking lot gate may be connected to the stopper 250 .

The rotating structure can be applied to various industrial fields (traffic safety signs, robots, production machinery fields, service fields, etc.) in addition to the blocking rods of parking lots.

rotating structure movement

Hereinafter, the operation of the rotating structure will be described in detail with reference to the accompanying drawings.

FIG. 5 is a perspective view illustrating the rotation structure illustrated in FIG. 4 in an open state, and FIG. 6 is a side view of the rotation structure illustrated in FIG. 5 . 5 and 6, no power is applied to the motor 5, and the third link 260 and the rotation center shaft 230 rotate by the restoring force of the spring 240, and accordingly the stopper 250 maintains a vertical state (open state). Thereafter, the vehicle may pass through a circuit breaker (not shown). In addition, the first and second links 210 and 220 rotate by the central axis of rotation 230 , and the axis link 100 maintains the direction shown in FIGS. 5 and 6 .

7 is a side view illustrating the rotation structure shown in FIG. 4 in a closed state. Referring to FIG. 7 , when the stopper 250 is switched to the closed state, the shaft link 100 is rotated counterclockwise around the first shaft 190 by the power applied to the motor 5 ( FIGS. 5 to 5 ). 7), it is rotated by 180° to have the same state as in FIG. 7 . At this time, the first and second links 210 and 220 rotate at the same time, and the rotation center shaft 230 is rotated counterclockwise by 90°. Accordingly, the stopper 250 is in a horizontal state to close the parking lot gate.

An open state (stopper 250 in a vertical state) as shown in FIG. 6 and a closed state (stopper 250 in a horizontal state) as shown in FIG. 7 are frequently repeated. Nevertheless, due to the simple structure and reliable power transmission of the shaft link 100, the rotation structure can have high durability.
