[0026] In one embodiment of the utility model, the end of the rotating shaft 2 away from the inner top of the mounting frame 1 is fixedly connected with a shielding plate 5, the bottom end face of the shielding plate 5 is fixedly connected with an upper gear ring 12, the inner bottom face of the bottom plate 4 is fixedly connected with a base 7, the top end face of the base 7 is fixedly connected with a limit rod 8, the limit rod 8 is hinged with the non-return rod 10 through the sleeved rotating shaft 9, the side wall of the non-return rod 10 is clamped with the upper gear ring 12, so that the upper gear ring 12 can only rotate counterclockwise but not clockwise, the rotating shaft 9 is fixedly connected with the non-return rod 10, the non-return rod 10 can rotate around the axis of the rotating shaft 9, the side wall of the rotating shaft 9 is fixedly connected with a coil spring 11, and the end of the coil spring 11 away from the rotating shaft 9 is fixedly connected to the limit rod 8. The inner bottom surface of the base 7 is fixedly connected with a hydraulic cylinder 13, the output end of the hydraulic cylinder 13 is fixedly connected with a transmission shaft 14, the end of the transmission shaft 14 away from the hydraulic cylinder 13 is fixedly connected with a lower gear ring 15, the lower gear ring 15 is meshed with the upper gear ring 12, when the lower gear ring 15 is meshed with the upper gear ring 12, the upper gear ring 12 will be unable to rotate, the top end surface of the bottom plate 4 is fixedly connected with a shielding ring 6, the shielding ring 6 does not contact the shielding plate 5, the bottom plate 4 does not contact the shielding plate 5, the axis of the bottom plate 4 coincides with the axis of the shielding plate 5, the bottom end surface of the shielding plate 5 is fixedly connected with a conical collar 16, the side wall of the transmission shaft 14 is sleeved with a mounting ring 17, and the top end surface of the mounting ring 17 is fixedly connected with a brush 18.
[0027] Under normal use, the door body 3 is pushed to rotate counterclockwise, and the upper gear ring 12 pushes the check rod 10 to rotate around the rotating shaft 9, so that the upper gear ring 12 can rotate normally, and the coil spring 11 pulls the check rod 10 to reset through elastic deformation. When the door body 3 is pushed clockwise, the limit rod 8 blocks the check rod 10 from rotating. At this time, the door body 3 cannot rotate clockwise, so that the door body 3 can only rotate clockwise, guiding the flow of people, diverting the flow of people, facilitating security inspection of the flow of people, and when encountering emergencies, it is necessary to lock the When the door body 3 is opened, the hydraulic cylinder 13 pushes the transmission shaft 14 to move upward, thereby engaging the upper gear ring 12 with the lower gear ring 15. The engagement of the upper gear ring 12 with the lower gear ring 15 blocks the upper gear ring 12 from rotating. At this time, the door body 3 is locked, so that people outside and inside the door cannot pass through, which has a good protective effect. At the same time, through the setting of the shielding ring 6, the gap between the shielding ring 6 and the shielding plate 5 is directed towards the rotating shaft 2, which reduces dust or garbage from falling into the locking assembly and improves the stability of the locking assembly.
[0028] In addition, a conical collar 16 is fixedly connected to the bottom end face of the baffle plate 5, a mounting ring 17 is sleeved on the side wall of the transmission shaft 14, and a brush 18 is fixedly connected to the top end face of the mounting ring 17. The brush 18 blocks the space between the upper gear ring 12 and the lower gear ring 15. At the same time, the brush 18 will not affect the rotation of the rotating shaft 2 and prevent debris from falling in. When the hydraulic cylinder 13 drives the transmission shaft 14 to move upward, the brush 18 also moves upward, which can further push out the debris and ensure the stable operation of the locking assembly.
[0029] In the utility model, when in use, the limit rod 8 limits the non-return rod 10 so that the door body 3 can only rotate counterclockwise. When encountering an emergency, the upper tooth ring 12 engages with the lower tooth ring 15, and then quickly locks the door body 3 to prevent it from rotating a short distance due to inertia, so that people inside and outside the door cannot pass through, thereby improving the protection effect of the revolving door. At the same time, the shielding ring 6 reduces the dust from falling into the non-return device. During the engagement of the upper tooth ring 12 and the lower tooth ring 15, the brush 18 pushes debris out of the non-return device, thereby improving the stability of the locking assembly.
[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
