With the increase of social demands, the revolving door is rapidly developed, various types of revolving doors are continuously developed and perfected, and the three-wing revolving door or the four-wing revolving door is more and more widely applied due to stronger stability and attractiveness.
The door leaves of the current three-wing or four-wing revolving door are directly fastened and connected on the turntables above and below the central shaft of the revolving door, and the door leaves rotate around the central column of the revolving door through motor driving or manual driving on the revolving door, so that the running of the revolving door is ensured to be passed. All gaps are of fixed design and are not adjustable. In this construction, a running gap of typically 35mm remains between the revolving door leaf and the outer stationary curved wall of the revolving door, which gap is sealed by means of a brush. Just because the existence in this 35mm clearance, in the in-service use of revolving door, can appear the pedestrian and snatch or prevent the condition such as clamping sensor malfunction, because there is the reason of braking distance in the running inertia of door leaf, the pedestrian just is in the narrow and small clearance of 35mm by the clip easily, causes the centre gripping injury to the pedestrian. In the process of saving people, people can only adopt a breaking and dismantling method, which causes property loss. The safety problem becomes an important potential safety hazard problem in the current revolving door industry, and the national standard defines the safety problem as a main danger area to remind pedestrians of safety because no good method is available for solving the safety problem.

Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1 to 4, the present invention provides a revolving door with retractable and slidable door leaves, which is a three-wing revolving door in this embodiment, and includes a central pillar 2 and three groups of door leaves 1, wherein an outer curved wall is disposed on an outer side of each door leaf 1, and a gap, for example, 35mm, exists between each door leaf 1 and the outer curved wall. The upper and lower both ends of center pillar 2 are provided with carousel 3 respectively, and door leaf 1 is rotatory around center pillar 2 through carousel 3. The upper end and the lower end of the center post 2 are provided with symmetrical shaft discs 4, the upper shaft disc is fixed on the upper turntable, and the lower shaft disc is fixed on the lower turntable. The door leaf 1 is connected to the shaft disc 4 through a sliding mechanism parallel to the door leaf, and the door leaf 1 can slide along the sliding mechanism in a direction toward the center pillar 2 (i.e., a rotation center).
The sliding mechanism comprises a linear guide rail 5 fixed on the shaft disc 4 and a sliding block 6 matched with the linear guide rail 5, the linear guide rail 5 is parallel to the door leaf 1, and the sliding block 6 is fixed with the door leaf 1 through a connecting piece. The linear guide rail 5 can adopt an SBR linear guide rail, and the slide block 6 is a bearing slide block.
In this embodiment, the sliding mechanism includes two sets of linear guide 5 fixed on the reel 4 and two sets of sliders 6 matched with the linear guide 5, and the two sets of linear guide 5 are respectively located two sides of the door leaf 1 and the distance between the two sets of linear guide 5 is greater than the thickness of the door leaf 1. The two groups of sliders 6 are fixed together through slider connectors 7, transition connectors 8 are fixed at the bottoms of the slider connectors 7, door leaf connectors 9 are fixed on one sides, facing the middle columns 2, of the door leaves 1, and the transition connectors 8 and the door leaf connectors 9 are fixed together, so that the slider connectors 7 and the door leaves 1 are fixed together.
A reset device is further arranged between the door leaf 1 and the shaft disc 4, the reset device in this embodiment is a hydraulic elastic device 10, one end of the hydraulic elastic device 10 is fixed on the shaft disc 4, the other end of the hydraulic elastic device is fixed on the door leaf connecting piece 9, and the hydraulic elastic device 10 can push the door leaf 1 to slide outwards for resetting.
The working principle and the specific implementation mode of the invention are as follows:
when the revolving door is in normal operation, the clearance between the outer side of the door leaf 1 and the outer curved wall is still the original clearance, for example 35 mm. When a pedestrian is extruded into the gap, the door leaf 1 is subjected to inward extrusion force, and the door leaf 1 slides to the rotating center along the linear guide rail 5 along with the sliding block 6, so that the distance between the outer side of the door leaf 1 and the outer curved wall is increased, and the pedestrian can get off in time. When the door leaf 1 loses the effect of the extrusion force, the hydraulic elastic device 10 pushes the door leaf 1 to slide outwards along the linear guide rail 5 under the effect of the restoring force until the door leaf is restored to the original position, and the subsequent normal operation of the revolving door is ensured. The whole action process does not need manual regulation and control, and can save pedestrians in distress in time without dismantling the revolving door, thereby avoiding unnecessary loss of manpower and property and achieving multiple purposes at one time.
In the present embodiment, the direction toward the center pillar is regarded as inward, and the direction away from the center pillar is regarded as outward.
The structures of the SBR linear guide rail and the bearing slider and the like matched with the SBR linear guide rail in this embodiment are the prior art, and are not described again.
The foregoing is directed to preferred embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. However, any simple modification, equivalent change and modification of the above embodiments according to the technical spirit of the present invention may be made without departing from the technical spirit of the present invention.
