Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 to 3, the hinge-concealed type double-sliding door structure of the present invention includes an upper hinge assembly 3a and a lower hinge assembly 3b for rotatably connecting a door leaf 2 to one side of a door frame 1, each of the upper hinge assembly 3a and the lower hinge assembly 3b includes a main body 31, a rotating shaft 32 extending and retracting in the main body 31, and a spring 33 for allowing the rotating shaft 32 to extend out of the main body 31, an upper fixing plate 4 is disposed on an upper portion of the door frame 1, an upper fixing hole 41 through which the rotating shaft 32 of the upper hinge assembly 3a passes is disposed on the upper fixing plate 4, a lower fixing plate 5 is disposed on a lower portion of the door frame 1, a lower fixing hole 51 through which the rotating shaft 32 of the lower hinge assembly 3b passes is disposed on the lower fixing plate 5, and the upper fixing hole 41 and the lower fixing hole 51 are in a coaxial position. The upper fixing hole 41 and the lower fixing hole 51 determine the position of the rotating shaft of the door leaf 2, the upper hinge assembly 3a and the lower hinge assembly 3b are elastic connecting pieces, hinge components are hidden at positions where the upper side and the lower side of the door leaf 2 are not easy to observe, and the appearance is concise. The spring 33 is compressed before assembly, and when the rotating shaft 32 is matched with the positions of the upper fixing hole 41 and the lower fixing hole 51, the spring 33 enables the rotating shaft 32 to pop out, so that the door leaf 2 can rotate in a range of not less than 180 degrees in the front and back direction, and a bidirectional door opening function is realized; when the door leaf 2 is detached, the door leaf 2 is only slightly lifted and then pulled outward, and the rotating shaft 32 of the lower hinge assembly 3b is firstly taken out of the lower fixing hole 51, so that the door leaf can be taken out. The lower hinge component 3b is arranged below the rotation axis of the door leaf 2, and the bearing force is larger than that arranged at the side of the door leaf 2.

As shown in fig. 2 and 3, the main body 31 includes a cylindrical portion 311, a panel portion 312 located at one end of the cylindrical portion 311, and a sealing piece 313 located at the other end of the cylindrical portion 311, the panel portion 312 has a through hole having an inner diameter smaller than that of the cylindrical portion 311, the rotation shaft 32 includes a thick portion 321, a thin portion 322, and a tapered portion 323 which are integrally formed, an outer diameter of the thick portion 321 is between an inner diameter of the cylindrical portion 311 and an inner diameter of the through hole 3121, an outer diameter of the thin portion 322 is smaller than that of the through hole 3121, the spring 33 is sandwiched between the sealing piece 313 and the thick portion 321, and the panel portion 312 is used to be screwed to the door leaf 2, so that the upper hinge assembly 3a and the lower hinge assembly 3b are firmly fitted into the door leaf 2. The cylindrical portion 311, the panel portion 312 and the sealing piece 313 form a cavity allowing the rotating shaft 32 to extend and retract without falling out, and the upper hinge assembly 3a and the lower hinge assembly 3b are preferably integrally cast members and are firmer than a welded structure.

As shown in fig. 3, the lower hinge unit 3b further includes a raising pipe 314 coaxial with the cylindrical portion 311, and the raising pipe 314 is connected to a side of the panel portion 32 facing away from the cylindrical portion 311. The heightening pipe 314 can keep the door leaf 2 away from the ground for a certain distance, so as to prevent the door leaf 2 from drooping and touching the ground to generate friction force for blocking the door opening. In practical application, the lower part of the door leaf 2 can be suspended in the air by increasing the height of the lower fixing sheet 4, so that the blocking force for opening and closing the door is reduced.

As shown in fig. 2 and 3, the bottom of the thick section 321 is provided with a circular groove 324 for holding the spring 33. The spring 33 has a portion located in the circular groove 324 so that its axis can be maintained substantially coaxial with the shaft 32, avoiding axial deflection of the shaft 32 when the spring 33 is compressed.

As shown in fig. 1 to 3, the upper fixing piece 4 is a sheet-like member screwed to the upper side of the door frame 1, the lower fixing piece 5 is an L-shaped member screwed to the side of the door frame 1, the upper fixing hole 41 is a tapered hole having a small top and a large bottom, and the lower fixing hole 51 is a tapered hole having a small bottom and a large top. Because the rotating shaft 32 is inserted into the upper fixing hole 41 and the lower fixing hole 51 by the elastic force of the spring 33, the tapered head 323 is more easily aligned with the tapered hole structure, and the assembly is convenient.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the utility model.
