Detailed Description

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

Example 1:

as shown in fig. 1 to 4, the utility model discloses a hidden indoor door hinge, include with first hinge 1 of key shaft 3 articulated and second hinge 2, first hinge 1 includes first bobbin 11 and the first stationary blade 12 that extends from first bobbin 11 tangential direction, second hinge 2 includes second bobbin 21 and the second stationary blade 22 that extends from second bobbin 21 tangential direction, is equipped with a plurality of first fixed orificess 121 on the first stationary blade 12, and first stationary blade 12 is located the tangent line outside of first bobbin 11 with the stationary plane of door frame 4, is equipped with a plurality of second fixed orificess 221 on the second stationary blade 22. The first fixing plate 12 is fixed on the door frame 4 by a screw passing through the first fixing hole 121, the second fixing plate 22 is fixed on the door leaf 5 by a screw passing through the second fixing hole 221, the door leaf 5 is provided with a notch 51 for fixing the second fixing plate 22, the notch 51 does not damage the panel of the door leaf 5, but a space must be left on the edge of the door frame 4 when the door leaf 5 rotates, the fixing surface of the first fixing plate 12 and the door frame 4 is positioned outside the tangent line of the first shaft tube 11 so as to leave the space, and the 90-degree rotation of the door leaf 5 is avoided being influenced. When the door leaf 5 is rotated. This indoor door hinge can hidden installation, does not influence the integrality of door outward appearance face, and compact structure can let the door leaf toward one-way opening and stop at specific aperture.

As shown in fig. 1 to 4, the first fixing plate 12 is provided with a plurality of equal-height cushion blocks 13 perpendicular to the axial direction of the first shaft barrel 11, and the first fixing holes 121 are located between adjacent equal-height cushion blocks 13, and the height of the equal-height cushion blocks 13 is greater than the height of the first shaft barrel 11. When screwing the screw, the equal-height cushion blocks 13 do not need to be punched. The elevated structure may be other structures that can increase the distance between the first fixing plate 12 and the doorframe 4, such as an E-shaped protrusion, an X-shaped protrusion, etc.

As shown in fig. 3, the thickness of each of the first fixing piece 12 and the second fixing piece 22 is not more than half of the outer diameter of the first shaft tube 11 and the second shaft tube 21, so that the first fixing piece 12 and the second fixing piece 22 can be closely attached to each other at one side when the door 5 is completely closed.

As shown in fig. 1, the first hinge 1 has a first shaft tube 11, and the second hinge 2 has two coaxial second shaft tubes 21, and the first shaft tube 11 and the second shaft tube 21 are inserted through and penetrated by the key shaft 3. The first shaft barrel 11 and the second shaft barrel 21 are arranged in an inserting mode, so that the whole hinge has higher bearing capacity. In practical applications, the first shaft cylinder 11 and the second shaft cylinder 21 can be provided in multiple numbers and in coaxial positions, and the difference between the numbers of the first shaft cylinder 11 and the second shaft cylinder 21 is only required to be not more than 1.

As shown in fig. 2, one end of the key shaft 3 is a fixing portion 31 having an outer diameter larger than the rest, and the fixing portion 31 is used for interference fit with the second shaft 21. The key shaft 3 is clamped on the second shaft 21 by the fixing part 31, so that the key shaft 3 can be prevented from falling out in the opening and closing process of the door leaf 5. The fixing portion 31 may also be interference fitted on the first shaft tube 11 if the first shaft tube 11 is on the outside.

As shown in fig. 2, the fixing portion 31 has a knurled structure. The knurling structure may be a cross-hatched or straight-grained structure for facilitating the insertion of the key shaft 3 into the first shaft cylinder 11 or the second shaft cylinder 21.

Example 2:

as shown in fig. 5, the difference from embodiment 1 is that: the first fixing piece 12 is in a zigzag shape with uniform thickness. That is, the raised manner is not used here, but the bending of the first fixing piece 12 itself is used to make room for the rotation of the door leaf 5.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
