Embodiment Construction

[0012] According to Figures 1 and 2, in the fixed revolving door curved wall 6 is the revolving door body 5, and the two sides of the curved wall 6 are fixed support columns 4; the support column 4 supports the fixed disk 2 and the revolving door ceiling 3, the revolving door body 5 and the hanging plate 1 are firmly connected together; the supporting column 4 supports the fixed frame 2. According to the attached Figure 5 And Figure 6 As shown, the hanging plate 1 is a convex table, and a permanent magnet 7 is installed on the inner ring surface of the big head. Picture 9 And Picture 10 As shown, there is a central circular hole at the top of the fixed plate 2 and a permanent magnet 8 on the top surface of the edge, as shown image 3 As shown, the positions of the permanent magnets 7 and 8 correspond, and the magnetic poles repel each other, and the relative area of ​​the permanent magnets must be large enough to ensure that sufficient repulsive force can be generated to suspen...

Abstract

A device of applying repulsion magnetic suspension to support a rotating door includes that permanent magnets with opposite magnetism are set between a hanger frame and a fixed frame to make the door suspend based on the theory of like things repel each other, unlike things attract each other, a permanent magnet is set at the outer plate of the ceiling board and a magnet is opposite magnetic pole is also set at the fixed frame correpsonding to it for preventing thedoor from tilting. Since the door is suspended, no friction is here, the door is easy to be pushed, power source, push bearing, the related driving systems andcontrol system are eliminated.

Description

Technical field [0001] This device belongs to the automatic revolving door for buildings. Background technique: [0002] Automatic revolving doors are widely used in various high-end restaurants, hotels, and office buildings, but the automatic revolving doors currently generally use thrust bearings to support the door body. Because the door body of the revolving door is very heavy, the general thrust bearing life time More than half a year will produce a lot of noise, which will greatly affect the use effect of the revolving door and increase the maintenance cost. In addition, because the door body is very heavy, using a motor to drive the revolving door will continue to consume energy and increase the cost of use. Summary of the invention: [0003] The purpose of the device is to provide a revolving door supporting device with simple structure, flexible rotation, no noise, and energy saving. [0004] In order to achieve the above-mentioned purpose, this device is realized by th...
