Description

Technical Field

[0001] This utility model relates to the field of furniture hinge technology, and in particular to a single-slot hinge that is easy to adjust. Background Technology

[0002] A hinge is a widely used mechanical device in daily life used to connect a movable door to a fixed wall, allowing relative rotation between the two. In furniture such as doors, windows, and cabinets, hinges are indispensable components, ensuring smooth opening and closing. While their structure may seem simple, they embody ingenious design.

[0003] Currently, traditional hinge bases all use a cross-shaped exposed structure. After the base is installed on the side panel, it occupies a large amount of space on the side panel, affecting the overall layout and aesthetics of the cabinet. At the same time, traditional door hinge designs also present many inconveniences during installation, especially in terms of screw pre-installation. This not only increases the difficulty and time cost of installation, but also affects the stability and lifespan of the door hinge.

[0004] Chinese utility model patent CN220336696U discloses a single-slot hinge base, belonging to the field of single-slot hinges. A single-slot hinge base includes: a base movable piece; a first mounting hole on the base movable piece; a base body connected to the base movable piece; a connecting seat connected to the base body; an outer shell fixedly connected to the connecting seat; a first connecting clip rotatably connected to the outer shell; a cup head rotatably connected to the first connecting clip, and the cup head and the first connecting clip correspond to each other; the cup head has multiple sets of second mounting holes, symmetrically arranged on the cup head. However, this patent uses an eccentric screw to connect to the connecting seat. The eccentric screw has both positioning and adjustment functions, therefore the eccentric screw needs to be tightly connected to the outer shell, making it difficult to adjust, and placing high demands on the manufacturing processes of both the eccentric screw and the outer shell.

[0005] Therefore, it is necessary to develop an easily adjustable single-slot hinge to solve these problems and improve installation efficiency and quality. Utility Model Content

[0006] The technical problem to be solved by this utility model embodiment is to provide a single-straight hinge that is easy to adjust.

[0007] To address the aforementioned technical problems, this utility model provides an easily adjustable single-piece hinge, comprising a base assembly fixed to a wall and a hinge body detachably mounted on the base assembly. The hinge body includes an arm, and the base assembly is disposed within the arm. The base assembly includes an outer base frame and an inner base frame connected vertically. The arm is movably connected to the outer base frame via a first fastening adjustment member and a first positioning adjustment member. After the inner base frame is fixed to the wall, the relative position of the hinge body and the base assembly in the length direction is adjusted by the first positioning adjustment member, and the first fastening adjustment member is then tightened to secure it.

[0008] Furthermore, the first positioning adjustment component includes a nut and an eccentric rotating shaft eccentrically disposed at the lower end of the nut. The nut passes through the first adjustment hole of the arm body and the eccentric rotating shaft is rotatably disposed in the positioning hole of the base frame.

[0009] Furthermore, the positioning hole is elongated along the width direction of the hinge, and the width of the positioning hole matches the diameter of the eccentric rotating shaft. When the first positioning adjustment member rotates, the eccentric rotating shaft slides in the positioning hole and moves along the length direction of the hinge.

[0010] Furthermore, the first fastening adjustment member is adjustable in the second adjustment hole of the arm body and is detachably connected to the connection hole of the base frame.

[0011] Furthermore, the base assembly is in the shape of a straight line, and a connector is provided on the inner frame of the base. The connector has a T-shaped limiting hook, and the outer frame of the base has a limiting protrusion that cooperates with the limiting hook.

[0012] Furthermore, the inner frame of the base is provided with a plurality of mounting holes along its length, and each mounting hole is provided with an assembly screw, and the base assembly is mounted on the wall by the assembly screw.

[0013] Furthermore, it also includes a second positioning adjustment member for adjusting the relative position of the hinge body and the base assembly in the width direction, the second positioning adjustment member passing through the connector and connected to the inner frame of the base.

[0014] Furthermore, a second fastening adjustment component is also provided in the third adjustment hole of the arm body, and the first fastening adjustment component passes through the third adjustment hole and is slidably disposed in the slide groove of the base frame.

[0015] Furthermore, both the first and second fastening adjustment components are adjusting bolts, and both the first and second positioning adjustment components are eccentric bolts.

[0016] Furthermore, the hinge body also includes a hinge cup, an outer rocker arm, an inner rocker arm, and a torsion spring that provides the hinge closing power. Both ends of the outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup and the arm body, respectively. The torsion spring is sleeved at the connection between the outer rocker arm and the arm body. The outer rocker arm and the inner rocker arm are rotatably connected to the hinge cup through U-shaped pins.

[0017] Implementing the embodiments of this utility model has the following beneficial effects:

[0018] The base assembly is connected to the arm tail via adjusting bolts and eccentric bolts, replacing the existing technology which uses only one eccentric bolt. The adjusting bolt and eccentric bolt have the functions of adjusting fastening and adjusting positioning, respectively. The eccentric bolt does not need to be tightly connected to the arm and is easy to turn, reducing the manufacturing and assembly process requirements of the eccentric bolt and the arm, and making it more widely applicable.

[0019] Users can quickly and conveniently open and close walls, cabinets, and doors using this single-straight hinge. The base assembly of this single-straight hinge is entirely in a straight line shape and is equipped with an eccentric bolt. It eliminates the mounting wings on the left and right sides of the base assembly in existing technology, making the base assembly more aesthetically pleasing. Furthermore, the base assembly is covered by the arm body, effectively avoiding safety hazards such as user scratches or hinge falling off during use. It better meets the needs of modern users and improves product safety.

[0020] The mounting holes eliminate the need for manual positioning. After measuring the installation position, the base assembly is placed in the installation position and can be installed directly. There is no need to remove the base assembly. The mounting screws are simply screwed into the mounting holes to quickly install the base assembly on the cabinet or wall. This solves the problem of low installation efficiency caused by the need to remove the base during installation of existing bases.

[0021] The eccentric bolts on the base assembly allow for vertical and horizontal position adjustment between the cabinet or wall and the door. Users can adjust the relative position between the cabinet or wall and the door according to their needs, effectively eliminating problems caused by inconsistent manufacturing specifications or misalignment during installation, which can prevent the furniture cabinet or wall from opening or closing properly or create gaps after closing, affecting usability and aesthetics. This greatly facilitates daily use. Attached Figure Description
