[0030] Embodiment 1

[0031] Reference Figures 1-2 In this embodiment, a door body rotating shaft structure is proposed for supporting a door body, especially a folding door. The door body rotating shaft structure can include:

[0032] The upper rotating shaft base is used to connect the top of the rotating center of the door body 21 and the door frame, and forms a rotating connection structure that elastically and detachably sleeves the door body 21 and the door frame, thereby completing the rotating connection of the door body 21. The upper rotating shaft base can include an upper fixed base 1 and an upper rotating shaft 2. The upper fixed base 1 can be installed on the top of the door frame and forms the rotating connection basis of the door body 21. The upper fixed base 1 can be a piece of iron with a sleeve hole 9, which can be directly fixed on the door frame or the guide rail 23 by bolts when the upper fixed base 1 is installed. The upper rotating shaft 2 can include a spring and a telescopic rod, which are cooperatively installed in the door body 21. The spring makes the telescopic rod slide outward, which will not be described in detail here. The upper rotating shaft 2 can also include a sleeve shaft 10, an upper fixed sleeve 12, and a lifting spring 20. The sleeve shaft 10 is provided with a limiting structure, which can be a stepped concentric cylindrical structure with a reduced radius. The sleeve shaft 10 has the upper fixed sleeve 12 axially slidingly nested at one end, and the portion exceeding the upper fixed sleeve 12 is provided with a limiting protrusion, which can limit the upper fixed sleeve 12 from disengaging from the sleeve shaft 10. The limiting protrusion can be completed by stamping after the upper fixed sleeve 12 and the sleeve shaft 10 are fixed. The lifting spring 20 is sleeved between the sleeve shaft 10 and the upper fixed sleeve 12. The other end of the sleeve shaft 10 is fixedly provided with a limiting piece 11, which is provided with a nesting portion away from the end of the sleeve shaft 10. The lifting spring 20 is used to make the sleeve shaft 10 slide towards the nesting portion. By providing the limiting structure on the sleeve shaft 10, the lifting spring 20 can easily exert an elastic force on the sleeve shaft 10. Of course, the limiting structure can also be a radial protrusion, which will not be described in detail here. The limiting piece 11 can be a circular ring structure. The end of the upper fixed sleeve 12 towards the limiting piece 11 can be fixedly provided with an outer edge, which can facilitate the control of the installation depth of the upper rotating shaft 2. During installation, an installation hole can be pre-formed at the rotating center position of the door body 21. The upper fixed sleeve 12 is installed in the installation hole, thereby completing the installation of the upper rotating shaft 2. The radius of the outer edge at the end of the upper fixed sleeve 12 is greater than the radius of the installation hole, thereby quantitatively controlling the installation depth of the upper rotating shaft 2. In order to improve the stability of the installation of the upper rotating shaft 2, a protruding line 13 can be fixedly provided on the outer side of the upper fixed sleeve 12, which can increase the stability of the sleeve. The sleeve shaft 10 can axially elastically slide inside the upper fixed sleeve 12.

Through the axial elastic sliding of the upper rotating shaft 2, the height requirement of the door body 21 can be adjusted, thereby facilitating the installation operation of the door body 21.

[0033] The lower rotating shaft base is used for connecting the bottom of the rotating center of the door body 21 and the door frame, and forms a connection structure which can detachably connect the door body 21 and the door frame and adjust the rotating position and the supporting height of the door body 21, so as to complete the rotating supporting structure of the door body 21. The lower rotating shaft base can comprise a lower rotating shaft 3 and a lower fixed base 4. The lower rotating shaft 3 can comprise a lower fixed sleeve 14, a screw 15 and a nail cap 16. One end of the screw 15 is fixedly connected with the nail cap 16, and the screw 15 is provided with a threaded structure. The lower fixed sleeve 14 is fitted on the screw 15. The side surface of the nail cap 16 is provided with a toothed structure. The supporting height can be adjusted by screwing the screw 15. Of course, the lower rotating shaft 3 is also directly provided with a screw, but it is not convenient to adjust, and the service life is also limited. The lower fixed base 4 can comprise a lower fixed main body 17 and a placing groove 18. The lower fixed main body 17 can be an L-shaped structure matched with the corner of the door, so as to be installed at the corner position of the door frame. The two edges of the lower fixed main body 17 are provided with screw holes, so that the corner of the lower fixed main body 17 can be fixedly installed by screws, thereby increasing the stability of the installation of the lower fixed main body 17. The placing groove 18 is arranged at the edge of the fixed main body 17, and the side edge of the placing groove 18 is provided with a toothed structure 19 matched with the nail cap 16. When the door body 21 is installed, the lower fixed sleeve 14 can be nested into the installation hole arranged at the bottom rotating center position of the door body 21, and then the nesting part of the sleeve-in shaft 10 on the door body 21 is nested into the sleeve-in hole 9 of the upper fixed base 1. The door body 21 is lifted, the sleeve-in shaft 10 is elastically stretched in the upper fixed sleeve 12, and the lower rotating shaft 3 at the bottom of the door body 21 is lifted along with the door body 21, so that the placement position of the nail cap 16 in the placing groove 18 can be adjusted, the rotating center position of the door body 21 is adjusted, and the door body is conveniently and quickly installed. The cross section of the placing groove 18 is a V-shaped structure, and the nail cap 16 is a circular truncated cone structure, so that the support of the nail cap 16 is facilitated, the contact area of the nail cap 16 and the placing groove 18 is increased, and the stability of the placement of the nail cap 16 is improved.
