Description

Technical Field

[0001] This utility model relates to the field of door and window hardware technology, specifically an adjustable hinge structure. Background Technology

[0002] Hinges with automatic closing function and hydraulic control of closing speed are becoming increasingly common. A utility model patent with patent number CN222314907U discloses a hinge structure including an installation box installed in the door frame and a receiving box installed in the door leaf. The receiving box contains a functional shaft for controlling the closing of the door leaf. A torque-transmitting connecting component is provided between the installation box and the receiving box. The installation box contains an installation component, including an installation panel installed within the installation box. The installation panel has at least one oblong hole at its upper and lower ends. The installation box contains an installation groove for accommodating the installation panel, and the bottom of the installation groove has a connecting hole adapted to the oblong hole.

[0003] The oblong hole on the mounting component in the above hinge structure can only adjust the position of the mounting component along the axis of the oblong hole. If the axis of the oblong hole is set longitudinally, only the size of the upper and lower door gaps can be adjusted. If the axis of the oblong hole is set laterally, only the alignment between the door leaf and the door frame after the door is closed can be adjusted. This design cannot simultaneously adjust the size of the upper and lower door gaps, the left and right door gaps, and the alignment between the door leaf and the door frame, making it difficult to adjust according to the actual situation. Once an adjustment is needed, the receiving box and the mounting box must be removed and reinstalled, which is very inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an adjustable hinge structure that addresses the shortcomings of the prior art, allowing for the adjustment of the positions of the mounting components and the receiving box according to actual needs, thereby achieving three-dimensional adjustment of the hinge.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hinge structure, including a receiving box, a mounting component, and a functional shaft disposed in the receiving box. A torque-transmitting connecting component is provided between the receiving box and the mounting component. The receiving box includes a receiving shell, a support, and an adjusting component. The receiving shell has a receiving cavity for accommodating the support and the adjusting component. The support includes a support body and adjusting lugs disposed at both ends of the support body along its length. Each adjusting lug has a first oblong groove. The adjusting component includes a separate or integrated first adjusting block and a second adjusting block. The first adjusting block and the second adjusting block are disposed at both ends of the support along its length. The end faces of the first adjusting block and the second adjusting block are flush with the end faces of the adjusting lugs. Both the first adjusting block and the second adjusting block have... The device has a concave surface for placing the adjusting lugs, and a first connecting hole adapted to the first waist-shaped groove on the concave surface. The receiving cavity has two receiving platforms along its length. The first adjusting block and the second adjusting block are respectively placed on the receiving platforms. The first adjusting block and the second adjusting block are provided with locking holes and adjusting holes. The receiving platforms are provided with second connecting holes and third connecting holes respectively at the positions of the locking holes and adjusting holes. The locking holes and adjusting holes are located on one side of the adjusting lugs.

The axial direction of the first waist-shaped groove and the second waist-shaped groove is the adjustment direction. The longitudinally set waist-shaped groove adjusts the size of the upper and lower door gaps, and the transversely set waist-shaped groove adjusts the flushness between the door leaf and the door frame after the door leaf is closed. The adjustment hole is threaded with a screw. By rotating the screw, the gap between the receiving box and the mounting part is changed, thereby adjusting the size of the left and right door gaps. The three adjustment methods are set on the hinge structure to achieve multi-dimensional adjustment.

[0007] A further feature of this invention is that the support body includes an L-shaped base and wall panels disposed at both ends of the base along its length. The adjusting lugs are disposed on the wall panels. The base includes a vertical plate and a horizontal plate. The vertical plate is provided with two spaced-apart first connecting protrusions.

[0008] The present invention, which has the above-mentioned features, has an L-shaped structure in the bracket body that can distribute the torque transmitted by the hinge during use and reduce local stress concentration.

[0009] A further feature of this invention is that the connecting assembly includes a first connecting arm, a second connecting arm, and a third connecting block. Two spaced-apart second connecting protrusions are provided on one side of the mounting component in the width direction. A third connecting protrusion is provided in the middle of the mounting component. The first connecting arm includes a first connecting shaft and a first support arm. An upper support arm and a lower support arm are provided at both ends of the first connecting shaft in the length direction, connecting the first support arm.

The third connecting protrusion is located within and hinged to the third hinge groove. One side of the third connecting block is placed within and hinged to the second hinge groove, and the other side passes through the upper and lower support arms and is placed between and hinged to the first connecting protrusion. The third connecting block is simultaneously hinged to both the upper and lower support arms.

[0010] The present invention, which has the above features, can achieve stable torque transmission between the accommodating box and the mounting parts through the multi-node hinge design of the first connecting arm, the second connecting arm and the third connecting block, ensuring uniform force when the door is closed.

[0011] A further feature of this invention is that: one end of the functional shaft is provided with a speed regulating component for adjusting the flow speed of hydraulic oil within the functional shaft; the speed regulating component extends to the outside of one side of the wall panel and a passive gear is provided at its end; a drive gear is rotatably mounted on the wall panel; and a space is left between the second adjusting block and the wall panel for the drive gear to rotate.
