Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the positional and orientational relationships indicated as "upper", "lower", "left", "right", "front", "rear", "vertical", "bottom", "inner", "outer", etc. are based on the positional and orientational relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
As shown in fig. 1-6, a concealed, hinged fire rated door comprising: a doorframe 1; a door panel 2; hinge assembly 3, hinge assembly 3 includes: the door frame comprises a fixed sleeve 31, wherein the fixed sleeve 31 is fixed on one side of an inner ring of the door frame 1, an accommodating cavity 31a is arranged in the fixed sleeve 31, a rotating shaft 31b is arranged in the accommodating cavity 31a, and the rotating shaft 31b can be rotatably connected with the fixed sleeve 31 or fixedly connected with the fixed sleeve, such as welding; a fixing sheet 32, the fixing sheet 32 being fixed to one side of the door panel 2; one end of the connecting piece 33 is rotatably connected with the rotating shaft 31b, the other end of the connecting piece 33 is fixedly connected with the fixing piece 32, the connecting piece 33 is U-shaped, one end of the connecting piece 33 is provided with a shaft sleeve 33a, and the shaft sleeve 33a is sleeved on the rotating shaft 31 b.
In this way, one end of the connecting element 33 is rotatably connected to the rotating shaft 31b in the fixing sleeve 31, and the other end of the connecting element 33 is located between the door panel 2 and the door frame 1, rather than protruding from the surface of the door panel 2 or the door frame 1, so that the connecting element 33 is not located at a clearly noticeable position, and then the fixing sleeve 31 is located at one side of the inner ring of the door frame 1, rather than at the front of the door frame 1, and the fixing sheet 32 is located at one side of the door panel 2, rather than at the front of the door panel 2, so that the fixing sleeve 31 and the fixing sheet 32 are not located at clearly noticeable positions, and thus the hinge assembly 3 is effectively hidden, thereby increasing the aesthetic property.
In addition, the fixing sleeve 31 is provided with a through hole 31c, and both ends of the rotating shaft 31b are fixed in the through hole 31 c. Therefore, when the rotating shaft 31b is fixed, the rotating shaft 31b can be fixed conveniently and the rotating shaft 31b can be positioned conveniently only by penetrating the rotating shaft 31b through the through hole 31c and then welding the rotating shaft 31b with the through hole 31c on the fixed sleeve 31.
