Description

Three-dimensional adjustable hinge

technical field

The invention belongs to the technical field of hinges, in particular to three-dimensional adjustable hinges.

Background technique

Hinge is a furniture copper ornament, commonly known as a hinge, is a metal piece that connects two parts of furniture and enables them to move. The structure of the traditional hinge is two-fold, usually a pair of metal leaves connected by pins, so that the door, cover or other swinging parts can be rotated.

After the hinge has been used for a long time, it is prone to loosening, which causes errors in the gap between the door leaf and the door frame, and it is often necessary to disassemble the door leaf to adjust the gap. And along with the development of interior decoration technology, people have higher and higher requirements for interior decoration grade. Most of the traditional door hinges are exposed on the facade, which destroys the overall decoration style. Moreover, in order to coordinate the decoration style and integrate the hinge with the door and the wall, people hope that the hinge can be adjusted conveniently and has a concealed function.

Contents of the invention

The object of the present invention is to solve the above problems and provide a three-dimensional adjustable hinge that is convenient for installation and adjustment and has a concealed function.

For this reason, the technical solution of the present invention is: a three-dimensional adjustable hinge, including a door frame side shell and a door leaf side shell, which are respectively fixed on the door frame and the door leaf, and the door frame side shell and the door leaf side shell are connected by a connecting arm device. There is a rectangular groove in the middle of the door frame side shell and the door leaf side shell, and an up and down adjusting device is fixed on the door frame side shell, and the up and down adjusting device includes two up and down adjusting screws, one up and down adjusting block and two adjusting Inclined block; the upper and lower adjustment screws pass through the adjustable inclined block and are inserted into both ends of the door frame side shell; the upper and lower adjustment blocks are center-symmetrical and placed in a rectangular groove in the middle of the door frame side shell, and the two ends of the upper and lower adjustment blocks pass through The fixing screw is connected to the adjusting slanting block; the adjusting slanting block and the upper and lower adjusting blocks have an inclined downward slope at the joint position; the two ends of the upper and lower adjusting blocks have a U-shaped mouth respectively, and a front and rear adjustment device is installed;

The front and rear adjustment devices include front and rear adjustment screws and front and rear adjustment blocks; the front and rear adjustment screws are stuck on the U-shaped openings at both ends of the upper and lower adjustment blocks, and the front ends of the front and rear adjustment screws pass through the front and rear adjustment blocks;

Left and right adjustment devices are respectively installed on both sides of the rectangular groove of the door leaf side shell, including left and right adjustment screws and left and right adjustment blocks; the left and right adjustment screws pass through the left and right adjustment blocks and are inserted into the two ends of the door leaf side shell; the connecting arm One end of the device is fixed on two front and rear adjustment blocks, and the other end is fixed on two left and right adjustment blocks.

Further, the connecting arm device includes a door frame side connecting arm, a door leaf side connecting arm, an outer connecting arm and a middle connecting arm; the door frame side connecting arm is fixed between two front and rear adjustment blocks by rivets, and the door leaf side connecting arm is fixed by a rivet It is fixed between the two left and right adjustment blocks; the outer connecting arm is "concave"; The two ends of the connecting arm and the middle connecting arm respectively utilize the roller flower shaft to pass through the door frame side connecting arm and the door leaf side connecting arm, and are connected therewith.

Further, the upper and lower adjusting screws have external threads, and the adjusting slanting block has internal threads, and the external threads of the up and down adjusting screws are screwed together with the internal threads on the adjusting slanting block.

Further, the front and rear adjustment screws have external threads, the front and rear adjustment blocks have internal threads, and the external threads of the front and rear adjustment screws are screwed together with the internal threads on the front and rear adjustment blocks.

Further, the left and right adjusting screws have external threads, the left and right adjusting blocks have internal threads, and the external threads of the left and right adjusting screws are screwed together with the internal threads on the left and right adjusting blocks.

The invention is installed on the side of the door and the door frame. When installing, two grooves with the same size as the door frame side shell and the door leaf side shell are opened on the side of the door and the door frame. Put the invention into it, then lock it with screws, and adjust it well. door gap, and then cover the decorative cover. The door frame side shell and the door leaf side shell are connected by a connecting arm device, and each connecting arm is connected by a roller flower shaft and can rotate around the roller flower shaft; so when the door frame and the door leaf are closed, the connecting arm device can be placed on the door frame side shell 1. Two rectangular grooves on the side shell of the door leaf, so that when the door is closed, the hinge can be integrated with the door and the wall.

The present invention can also adjust the position of the door leaf in three directions without disassembly:

1. Up and down adjustment: Since the external thread of the up and down adjusting screw is screwed with the internal thread on the adjusting inclined block, and the up and down adjusting screw is inserted into the side shell of the door frame; so when the up and down adjusting screw is rotated, the up and down adjusting screw is not separated from the side shell of the door frame. Only the screwed threads drive the adjusting slanting block, so that the adjusting slanting block moves along the up and down adjusting screws. Both the adjusting slant block and the up and down adjusting block have an inclined downward slope at the joint position, which makes the adjusting slant block drive the up and down adjusting block to move in the direction vertical to the up and down adjusting screw; The connecting arm device is connected, so the up and down adjustment block drives the door leaf through the connecting arm device, so that the door leaf moves up and down relative to the door frame to realize up and down adjustment;

2. Front and rear adjustment: Since the front and rear adjustment screws are stuck on the U-shaped openings at both ends of the upper and lower adjustment blocks, the front ends of the front and rear adjustment screws pass through the front and rear adjustment blocks, and the external threads of the front and rear adjustment screws are screwed together with the internal threads on the front and rear adjustment blocks; When the front and rear adjustment screws are rotated, the front and rear adjustment screws do not move on the upper and lower adjustment blocks, but only drive the front and rear adjustment blocks through the twisted threads, so that the front and rear adjustment blocks move along the front and rear adjustment screws, thereby driving the connecting arm device connected with the front and rear adjustment blocks, so that The door leaf connected with the connecting arm device moves left and right relative to the door frame to realize front and rear adjustment;

3. Left and right adjustment: because the left and right adjustment screws pass through the left and right adjustment blocks and are inserted into both ends of the door leaf side shell, and the external threads of the left and right adjustment screws are screwed together with the internal threads on the left and right adjustment blocks. Therefore, when the two left and right adjustment screws are rotated, the left and right adjustment screws are not separated from the door leaf side shell, and the left and right adjustment blocks are only driven by the twisted threads, so that the left and right adjustment blocks move along the left and right adjustment screws, and the left and right adjustment blocks are connected with the connecting arm device, thereby Make the distance between the door leaf and the door frame change, realize left and right adjustment.
