When the lock tongue 72 is stuck in the folding wing limiter 5, the folding wing limiter 5 is fixed. At this time, the door leaf 3 of the revolving door is fixed in the direction of the bottom of the upper disk 1. When the lock tongue 72 is disengaged from the folding wing limiter 5, the folding wing limiter 5 can be rotated, and the rotation simultaneously drives the folding wing shaft 4 below to rotate. At this time, the door leaf 3 of the revolving door also rotates accordingly. An entry and exit channel can be left by rotating the direction of the door leaf 3 to allow people to pass quickly.
[0026] like Figure 3 As shown, the upper disk 1 is provided with a first through hole 11 and a second through hole 12, the outer circumference of the upper disk 1 is circular, the first through hole 11 is arranged at the center of the upper disk 1, the center of the first through hole 11 is the same as the center of the upper disk 1, the number of the second through holes 12 is multiple, the number of the second through holes 12 is the same as the number of the door leaves 3, the figure surrounded by the centers of the multiple second through holes 12 is a regular polygon, and the number of sides of the regular polygon is the same as the number of the second through holes 12, if it is a three-wing revolving door, it is an equilateral triangle, if it is a four-wing revolving door, it is a square, the center of the regular polygon coincides with the center of the upper disk 1, so that when the door leaves 3 of the revolving door are in the initial position, the angles between adjacent door leaves are the same.
[0027] like Figure 4 As shown, there are multiple folding wing shafts 4, and the number of the folding wing shafts 4 is the same as the number of the second through holes 12. The folding wing shafts 4 pass through the second through holes 12 and are rotatably connected to the upper disk 1.
[0028] There are multiple folding wing limiters 5, and the number of the folding wing limiters 5 is the same as the number of the second through holes 12. The outer periphery of the folding wing limiter 5 is a regular polygon, and the number of sides of the regular polygon is the same as the number of the second through holes 12. If it is a three-wing revolving door, it is an equilateral triangle, and if it is a four-wing revolving door, it is a square. The folding wing axis 4 is arranged at the center of the regular polygon so that the distance from each corner of the folding wing limiter 5 to the folding wing axis 4 is equal.
[0029] like Figure 5 As shown, an upper sleeve 8 is arranged in the first through hole 11, and the upper sleeve 8 is arranged on the top of the central column 2. The folding wing fixing member 6 is sleeved on the outside of the upper sleeve 8 and fixed above the upper disk 1. The folding wing fixing member 6 is provided with a fixing groove 61. The number of the fixing grooves 61 is multiple, and the number of the fixing grooves 61 is the same as the number of the second through holes 12. The fixing groove 61 is arranged between the first through hole 11 and the second through hole 12, and the line connecting the first through hole 11 and the center of any second through hole 12 passes through the center of the fixing groove 61 close to the second through hole 12, so that the locking assembly 7 placed in the fixing groove 61 is arranged relative to the folding wing fixing member 5.
[0030] There are multiple locking components 7 , and the number of the locking components 7 is the same as the number of the second through holes 12 . The bottom of the locking component 7 is placed in the fixing groove 61 and is connected to the folding wing fixing piece 6 .
[0031] like Figure 6 As shown, the locking assembly 7 includes an electric latch 71, which is fixed above the fixing slot 61, and the lock tongue 72 is arranged in the fixing slot 61 below the electric latch 71 and is elastically connected to the fixing slot 61 through a spring 73, and the spring 73 is fixed in the fixing slot 61 through a spring pressing member 74, and the lock tongue 72 extends out of the fixing slot 61 and is stuck in the folding wing limiter 5 by the elastic force of the spring 73, and an electric latch slot 72b is arranged on the top of the lock tongue 72, and the length direction of the electric latch slot 72b is the same as the length direction of the spring 73. A magnetic piece is provided in the latch slot 72b, and the magnetic piece is arranged at one end of the electric latch slot 72b away from the spring. The electric lock tongue 71a of the electric latch 71 is extended and inserted into the electric latch slot 72b. At this time, the magnetic piece arranged at one end of the electric latch 72 is moved toward the electric lock tongue 71a by the action of the magnetic force. At this time, the spring 73 is squeezed, and the lock tongue 72 moves in the direction away from the folding wing limiter 5 and disengages from the folding wing limiter 5. When the electric lock tongue 71a retracts into the electric latch 71, the magnetic piece disengages from the electric lock tongue 71a, and the lock tongue 72 is extended out of the fixed slot 61 by the spring elastic force 73 and is stuck in the folding wing limiter 5.
[0032] like Figure 7 As shown, a groove 72a is provided on the locking tongue 72, and the shape of the groove 72a matches the corner of the regular polygon on the outer periphery of the folding wing limiting member 5, so that when the locking tongue 72 contacts the folding wing limiting member 5, a corner of the folding wing limiting member 5 is inserted into the groove 72a.
[0033] like Figure 8-9As shown, taking a three-wing revolving door as an example, during normal use, the three door leaves 3 of the revolving door are respectively fixed at the bottom of the upper disc 1 and rotate with the central column 2 as the center. When the flow of people is large, the locking assembly 7 is used to control the lock tongue 72 to disengage from the folding wing limiter 5, and one door leaf 3 of the revolving door is rotated under the upper disc 1 through the folding wing shaft 4. Since the folding wing limiter 5 is an equilateral triangle, when the adjacent angles of the folding wing limiter 5 are aligned with the lock tongue 72, the rotation angle is 120°. At this time, two of the door leaves 1 are rotated 120° clockwise and 120° counterclockwise, so that the three door leaves 1 are parallel, and people can walk directly through the passage next to the door leaf 1 without waiting, thus saving waiting time.
[0034] If it is a four-wing revolving door, the principle is the same as that of a three-wing revolving door. In this case, the folding wing limiter 5 is a square, and the angle of rotation of the door leaf 3 is 90°. When the flow of people is large, two of the spaced door leaves 1 are rotated 90° clockwise (or counterclockwise) to make the four door leaves 1 parallel. People can walk directly through the passage next to the door leaf 1 without waiting, thus saving waiting time.
