As shown in fig. 1-5, when the device of the present invention is in the initial state, the torsion spring 20 is in the relaxed state, the rear end surface of the opening/closing type gate 16 is just in contact with the front end surface of the gate baffle 21, the rotation limiting spring 25 is in the relaxed state, the rotation limiting block 28 is just partially positioned in the stopping cavity 32, the control slider 36 is just in contact with the right control contact block 33, the centrifugal spring 49 is in the relaxed state, the centrifugal friction block 53 is just completely positioned in the centrifugal spring cavity 52, the unfolding spring 56 is in the stretched state, the unfolding plate 66 is just completely positioned in the folding cavity 63, and the unfolding plate 66 is just in contact with the folding contact block 67;

sequence of mechanical actions of the whole device:

in the peak period of non-class-getting and leaving, if the student uses the entrance guard key to correspond to the card reader 12, the card reader 12 sends a signal to enable the gate electromagnetic switch 11 to work, so that the limitation on the opening-closing gate 16 is removed, and the student can just open the opening-closing gate 16;

when the peak period of the previous class and the next class arrives, the motor 18 is automatically started, so that the motor main shaft 50 is driven to rotate forwards, the centrifugal turntable 51 and the threaded sleeve 35 are driven to rotate, the threaded sleeve 35 drives the control slider 36 to slide leftwards, when the left end face of the control slider 36 is in contact with the left end wall of the control sliding cavity 34, the control slider 36 is just in contact with the left control contact block 33, the left control contact block 33 can disconnect the card reader 12 from the gate electromagnetic switch 11, and simultaneously connect the card reader 12 with the rotary electromagnet 24, so that the use in the subsequent peak period is facilitated, and meanwhile, the motor main shaft 50 just cannot drive the threaded sleeve 35 to rotate continuously;

the centrifugal turntable 51 drives the centrifugal friction block 53 to rotate, the centrifugal friction block 53 overcomes the centrifugal spring 49 to slide outwards under the action of centrifugal force until the centrifugal friction block is just contacted with the driven friction wheel 48, so as to drive the driven friction wheel 48 to rotate, the driven friction wheel 48 drives the driven friction shaft 47 to rotate, so as to drive the turbine 40 to rotate, the turbine 40 and the driven friction shaft 47 generate a self-locking effect, so as to prevent the expansion plate 66 from rotating under the action of the expansion spring 56, the turbine 40 drives the self-locking driving shaft 39 to rotate, so as to drive the self-locking main bevel gear 38 to rotate, the self-locking main bevel gear 38 drives the self-locking auxiliary bevel gear 41 to rotate, so as to drive the self-locking driven shaft 42 to rotate, the self-locking driven shaft 42 drives the transmission wire wheel 43 to rotate, so as to loosen the transmission pull rope 45, the expansion slide outwards under the action of the expansion spring 56 after the tension of the expansion, therefore, the unfolding plate 66 is driven to rotate by the unfolding half gear ring 62, when the outer end face of the unfolding sliding block 61 is in contact with the unfolding contact block 55, the unfolding plate 66 is right vertical to the opening-closing type gate 16, so that the unfolding of the cross revolving door is realized, and meanwhile, the unfolding contact block 55 sends a signal to stop the motor 18;

when a student uses an access key to correspond to the card reader 12, the card reader 12 can not enable the gate electromagnetic switch 11 to work right at the moment, the card reader 12 can send a signal right to enable the rotary electromagnet 24 to be electrified for a certain time, the rotary electromagnet 24 attracts the rotation limiting magnet 27, so that the rotation limiting block 28 is driven to overcome the rotation limiting spring 25 to slide leftwards until the rotation limiting block is completely positioned in the rotation limiting cavity 26, and the student can push the rotary door 14 or the expansion plate 66 to rotate ninety degrees around the rotary door rotating shaft 13 and then pass through the cavity 22 through opening and closing;

when the rotating door 14 or the unfolding plate 66 rotates ninety degrees, the rotating door 14 or the unfolding plate 66 drives the cross rotating block 30 and the circumferential magnet 31 to rotate ninety degrees through the rotating door rotating shaft 13, at the moment, the stop magnet 29 and the circumferential magnet 31 attract each other, so that the rotating door 14 and the unfolding plate 66 are finally kept at a certain position, the subsequent rotation limiting block 28 limits the cross rotating block 30, when the rotating electromagnet 24 stops working, the rotation limiting block 28 slides outwards to be partially positioned in the stop cavity 32 under the action of the rotation limiting spring 25, and therefore the limiting effect on the circumferential magnet 31 and the cross rotating block 30 is realized, and other people are prevented from passing through the cavity 22 through opening and closing during the rush hour;

after the peak period of the last class and the next class, if the driven friction cavity 46 is just corresponding to the centrifugal rotation cavity 54, the host tube enables the motor 18 to rotate reversely, if the driven friction cavity 46 is not corresponding to the centrifugal rotation cavity 54, the host tube enables the card reader 12 to send a signal to enable the rotary electromagnet 24 to work by using an entrance guard key, thereby finally removing the limiting and limiting effect on the rotary door 14 and the unfolding plate 66, further pushing the rotary door 14 to rotate until the driven friction cavity 46 is corresponding to the centrifugal rotation cavity 54, enabling the motor 18 to rotate reversely, enabling the motor 18 to drive the motor spindle 50 to rotate reversely, further enabling the control slide block 36 to reset, enabling the control slide block 36 to just contact with the right control contact block 33, enabling the card reader 12 to be just connected with the gate electromagnetic switch 11 by the right control contact block 33, enabling the card reader 12 to be disconnected with the rotary electromagnet 24, meanwhile, enabling the transmission reel 43 to rotate reversely to drive the unfolding slide block 61 to overcome the inward sliding of the unfolding, therefore, the unfolding plate 66 is finally reversely reset, the unfolding plate 66 is just contacted with the folding contact block 67, and the folding contact block 67 sends a signal to stop the motor 18, so that the folding of the cross revolving door is completed, and meanwhile, the folding of students with more articles is facilitated.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
