Detailed Description

The technical solutions of the present invention will be explained and explained in detail with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement the present invention.

Referring to fig. 1, a novel adjustable door hinge includes a leaf hinge 2 and a frame hinge 1, both of which are provided with a shaft cylinder. The novel fan hinge assembly is characterized by further comprising a fan hinge back plate 4, a fan hinge positioning back plate 3, a frame hinge back plate 5, a frame hinge adjusting block 11 and a fast-assembling mechanism 10. Wherein, the middle milling flutes of the shaft barrel part of the frame hinge 1 are embedded and installed in the shaft barrel of the fan hinge 2. The leaf hinge 2 and the frame hinge 1 are hinged through the hinge shaft 6, and the nylon sleeves 7 are further mounted at the two ends of the shaft barrel of the leaf hinge 2 to play a role in lubrication. Nylon sleeve 7 is tubular structure, outwards turns out the beam barrel tip of being convenient for block hinge 2 at the edge of one of them tip, and tubular structure supplies hinge shaft 6 to penetrate in order to reduce the friction between hinge shaft 6 and the beam barrel.

The hinge shaft 6 is a round rod-shaped structure, a clamping groove is arranged at a proper position, a shaft hole is formed in the side wall of the shaft cylinder at the corresponding position of the frame hinge 1, and after the hinge shaft 6 penetrates through the hinge 2 and the frame hinge 1, a jackscrew 14 penetrates through the shaft hole and abuts against the clamping groove, so that the hinge shaft 6 can be fixed on the frame hinge 1 and becomes a hinge whole.

The fan hinge back plate 4 is in a pre-installation form and is used for being pre-installed and fixed in a fan section bar cavity, and the fan hinge back plate 4 is specifically fixedly installed on a fan section bar through a fan hinge installation screw 9. Fan hinge location backplate 3 plays location and regulation effect at fan hinge backplate 4 and the 2 intermediate positions of fan hinge. Fan hinge location backplate 3 is installed on the C type notch of fan section bar, and fan hinge location backplate 3 is equipped with the location limit and is used for with the C type notch joint of fan section bar, be convenient for fan hinge 2 location installation, in the one side design towards fan hinge 2 there is the arch, corresponding, fan hinge 2 towards the one side of fan hinge location backplate 3 have the recess of mutually supporting with it, the arch can insert the recess, realizes the joint.

Adjusting screw 8 about installing on fan hinge location backplate 3 is equipped with the regulation screw that adjusting screw 8 passed about supplying on fan hinge 2, during the installation, about the first screw in of adjusting screw 8 pass the regulation screw of fan hinge 2 screw in fan hinge location backplate 3 again. The fixing between the fan hinge 2 and the fan hinge positioning back plate 3 is completed by a fan hinge mounting screw 9.

The frame hinge back plate 5 is used for being pre-installed and fixed in a cavity of a frame section bar and is fixed on the frame section bar through a frame hinge installation screw 13. A frame hinge adjusting block 11 is installed on the lower portion of the frame hinge back plate 5, and an upper adjusting screw 12 and a lower adjusting screw 12 are installed on the frame hinge adjusting block 11. Specifically, the frame hinge adjusting block 11 is a longitudinal block structure with a back edge, a longitudinal screw hole is formed in the block structure for an upper adjusting screw 12 and a lower adjusting screw 12 to penetrate through, and the back edge is used for being pressed by the frame hinge 1 after the upper and lower positions are adjusted so as to improve stability.

The frame hinge 1 is also provided with a quick-mounting mechanism 10 which can quickly fix the frame hinge 1 on the frame section. Referring to fig. 4, the quick-assembly mechanism 10 is a three-level step rivet, the lowermost step is in a truncated cone shape with two sides cut into parallel planes, and the middle of the lowermost step may have a mounting hole 102, which may be an inner hexagonal hole. During the use, can directly detain on the frame notch when the both sides plane of lower floor's ladder 101 is parallel with frame section bar notch, then can rotate 90 degrees fast-assembling mechanism 10 with special spanner, fast-assembling mechanism 10 can the joint realize quick installation function in the C type notch of frame like this. If the inner hexagonal mounting hole is formed, the quick-assembly mechanism can be rotated by embedding a tool into the mounting hole, and if the inner hexagonal mounting hole is not formed, other modes which can be relatively fixed with the quick-assembly mechanism can be adopted, such as clamping planes on two sides to rotate the quick-assembly mechanism.

During installation, the frame hinge 1 is installed and fixed on the frame section bar, then the frame hinge 1 is fixed on the frame hinge back plate 5 through the frame hinge installation screw 13, and the frame hinge 1 presses the frame hinge adjusting block 11, so that the frame hinge adjusting block 11 cannot fall off.

After the adjustable door hinge is installed, fine adjustment of the vertical position and the transverse position can be carried out. As shown in fig. 2, when the vertical relative position between the frame section bar and the sash section bar needs to be adjusted, that is, the vertical relative position relationship between the door frame and the door leaf, the frame hinge mounting screw 13 is loosened first, the upper and lower adjusting screw 12 is rotated by a hexagonal wrench, and then the frame hinge 1 is driven to move vertically, so that the vertical relative position between the frame hinge 1 and the frame section bar can be changed, and after the frame hinge mounting screw 13 is adjusted to a proper position, the purpose of vertical adjustment is achieved, and the adjustment range is +/-3 mm.

When the transverse relative position between the frame section bar and the leaf section bar needs to be adjusted, namely the transverse relative position relation between the door frame and the door leaf, the leaf hinge mounting screw 9 is firstly loosened, the left and right adjusting screw 8 is rotated by a hexagonal wrench, and then the leaf hinge 2 is driven to transversely move (mutually close or far away) relative to the leaf hinge positioning back plate 3, the transverse relative position between the leaf hinge 2 and the leaf section bar can be changed, after the appropriate position is adjusted, the leaf hinge mounting screw 9 is fixed, so that the transverse adjusting purpose is achieved, and the adjusting range is-1 mm- +2mm.

Through the adjustable door hinge, not only can the frame section bar be installed quickly, but also the relative position relation of the frame section bar and the sash section bar in the transverse direction and the longitudinal direction can be adjusted conveniently after installation, and the adjusting space of the hinge is greatly increased, so that convenience is brought to the processing, manufacturing and installation of the door, and the technical effect is more prominent particularly for the installation and use of an ultra-large door.

The inventive concept is explained in detail herein using specific examples, and the above description of the embodiments is only used to help understand the core idea of the present invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are intended to be included within the scope of the present invention.
