According to the hinge mechanism of the non-standard door, a hexagon wrench is inserted into an inner hexagonal block, rotates and drives a threaded column to rotate, so that a locking block in threaded connection with the outer side of the threaded column moves downwards, then limitation and extrusion of the locking block to an abutting column are relieved, and therefore a worker can twitch an L-shaped fixing plate towards one side; the non-standard door leaf acting force is converted into the acting force of the L-shaped fixing plate moving towards one side through the metal hinge, and therefore the acting force of the L-shaped fixing plate is transferred to the steel door frame through the locking block and the abutting column. Therefore, the stability of the non-standard door leaf after installation is guaranteed.

Description

Technical Field

[0001] The utility model relates to the technical field of non-standard doors, in particular to a hinge mechanism for non-standard doors. Background Art

[0002] Non-standard doors refer to doors with non-standard sizes, non-standard styles or customized according to specific needs. They are a hardware product used to improve the anti-theft security of residential and commercial buildings. Common non-standard doors are simply processed into door frames and door leaves with different panels, then sprayed, and finally assembled with hinges and locks. They vary in size and shape. According to the different materials of non-standard doors, they can be divided into steel non-standard doors, wooden non-standard doors and aluminum alloy non-standard doors. Among them, steel non-standard doors have high strength, durability and good anti-theft performance. Steel non-standard doors can adopt different surface treatment processes, such as plastic spraying, baking paint, etc., to make them have different colors and textures.

[0003] In the current existing technology, the door leaf and door frame of steel non-standard doors are connected by metal hinges. First, holes for fixing need to be opened on the door leaf and the door frame, and then locking screws are passed through the metal hinges and connected to the door leaf and the door frame. Since the steel non-standard doors are frequently opened and closed during use, the connection between the metal hinges and the door leaf will be deformed, causing the door leaf to sag, and the metal hinges need to be replaced regularly. Since locking screws are used for installation, the metal hinges are deformed and the screws are stuck, which makes disassembly inconvenient. Therefore, a hinge mechanism for non-standard doors is proposed to solve the above problem. Utility Model Content

It solves the problem that the connection between the metal hinge and the door leaf will be deformed and cause the door leaf to sag due to the frequent opening and closing of the door leaf during use of steel non-standard doors, and the metal hinge needs to be replaced regularly. Since locking screws are used for installation, the metal hinge will get stuck with the screws after deformation, making disassembly inconvenient.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a hinge mechanism for a non-standard door, comprising a steel door frame, a non-standard door leaf arranged in the steel door frame, a lock arranged on the non-standard door leaf, and a hinge mechanism and a control structure arranged on the steel door frame;

[0008] Furthermore, the non-standard door leaf is installed inside the steel door frame, and the lock is fixedly installed on the steel door frame.

[0009] Furthermore, the guide component includes a guide plate, which is fixedly installed on the rear side wall of the inner cavity of the installation frame. A guide groove is provided on the back side of the L-shaped fixing plate, and the outer surface of the guide plate is slidably connected to the inner wall of the guide groove.

[0010] Furthermore, a rectangular groove is provided on the metal hinge, and one end of the L-shaped fixing plate passes through the rectangular groove and extends to the outside of the metal hinge.

[0011] Furthermore, a circular groove is provided on the steel door frame, a bearing is fixedly installed inside the circular groove, one end of the threaded column passes through the bearing and extends to the outside of the steel door frame, and the inner circumferential wall of the bearing is fixedly connected to the outer surface of the threaded column.

A limiting groove is opened on the front side of the locking block, and the inner wall of the limiting groove is slidably connected to the outer surface of the I-shaped limiting strip.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The hinge mechanism of the non-standard door is provided with a hinge mechanism and a control structure, which realizes that a hexagonal wrench is inserted into the inner hexagonal block, rotated and drives the threaded column to rotate, so that the locking block connected to the outer thread of the threaded column moves downward, thereby releasing the restriction and squeezing of the locking block on the abutment column, so that the staff can pull the L-shaped fixing plate to one side, thereby releasing the fixation of the L-shaped fixing plate on the metal hinge, thereby facilitating the disassembly and replacement of the deformed metal hinge, and converting the force of the non-standard door leaf into a force for moving the L-shaped fixing plate to one side through the metal hinge, so that the locking block and the abutment column are used to transfer the force of the L-shaped fixing plate to the steel door frame, thereby ensuring the stability of the non-standard door leaf after installation, and enhancing the practicality of the hinge mechanism of the non-standard door.
