Technical Field
[0001] This utility model relates to the field of furniture hinge technology, and in particular to a novel single-slot hinge. Background Technology
[0002] Currently, traditional hinge bases mostly use a four-hole base structure made of aluminum or zinc alloy, fixed to the wall panel from the left and right. After the base is installed on the side panel, it occupies a large space on the side panel, which is particularly problematic in scenarios such as bathroom mirror cabinets with an inner width ≤95mm. This affects the overall layout and aesthetics of the cabinet, and users are easily bumped into the fixed base, causing scratches. Furthermore, the large space required and high manufacturing cost do not meet production and user needs. Moreover, different door thicknesses from 16mm to 25mm require different hinge specifications; the arm length of a standard straight hinge is usually 95mm-100mm, which can easily prevent installation on narrow cabinets. This not only increases the difficulty and time cost of installation but also affects the stability and lifespan of the hinge.
[0003] Chinese patent document CN214463420U, published on October 22, 2021, discloses a base stabilization and adjustment structure for a furniture hinge. The structure includes a hinge body and a fixed base that are detachably connected. The fixed base includes a fixing component and a connecting component, both of which are in a straight line shape, with an adjusting component positioned at their midpoint. The fixing component and the connecting component are adjusted in position via the adjusting component. The hinge body is detachably mounted on the connecting component, and a hinge clearance portion is provided on it corresponding to the adjusting component. However, the fixing component and the connecting component are connected by a guide shaft, resulting in complex assembly and increased arm length, making it unsuitable for use in narrow cabinets. Utility Model Content
[0004] The technical problem to be solved by this utility model embodiment is to provide a novel one-piece hinge.
[0005] To address the aforementioned technical problems, this utility model provides a novel one-piece hinge, comprising a fixed base and a hinge body detachably mounted on the fixed base. The hinge body includes an arm, and the fixed base is disposed within the arm. The fixed base includes an outer base frame and an inner base frame. The outer base frame has a slot along its length, and the inner base frame has a limiting step and a limiting block. The limiting step slides the inner base frame within the slot, and the limiting block secures it in place. The outer base frame is made of metal, and the inner base frame is made of plastic.
[0006] Furthermore, the fixed base is in the shape of a straight line, the outer frame of the base has a locking part that cooperates with the limiting step, and the limiting block abuts against the lower part of the outer frame of the base.
[0007] Furthermore, the front and rear parts of the arm body are respectively provided with screw adjustment components and eccentric adjustment components, and the arm body is movably connected to the base frame through the screw adjustment components and the eccentric adjustment components.
[0008] Furthermore, the inner frame of the base is provided with a first mounting hole and a second mounting hole along its length direction. The first mounting hole is located below the through hole of the arm body, and the second mounting hole is located behind the tail of the arm body.
[0009] Furthermore, both the first mounting hole and the second mounting hole are provided with mounting screws, and the fixed base is installed on the cabinet by the mounting screws.
[0010] Furthermore, the arm body is provided with a first adjustment hole and a second adjustment hole along its length direction.
[0011] Furthermore, the outer frame of the base is provided with a sliding groove and a positioning hole along its length.
[0012] Furthermore, the screw adjusting member is disposed within the first adjusting hole, and the screw adjusting member passes through the first adjusting hole and is slidably disposed within the slide groove.
[0013] Furthermore, the eccentric adjustment component is disposed in the second adjustment hole. The eccentric adjustment component includes a nut and an eccentric rotating shaft eccentrically disposed at the lower end of the nut. The nut passes through the second adjustment hole and the eccentric rotating shaft is rotatably disposed in the positioning hole.
[0014] Furthermore, it also includes a damping device, which is disposed in the front part of the arm body. The damping device includes a support, a linkage, and a damping element.

[0028] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0029] like Figure 1-6 As shown, a novel straight hinge includes a fixed base 1 and a hinge body detachably mounted on the fixed base 1. The hinge body includes a hinge cup 2, an arm body 3, an inner rocker arm 4, an outer rocker arm 5, a torsion spring 6, and a damping device 7. Both ends of the outer rocker arm 5 and the inner rocker arm 4 are rotatably connected to the hinge cup 2 and the arm body 3, respectively. The torsion spring 6 is sleeved at the connection between the outer rocker arm 5 and the arm body 3. The damping device 7 and the fixed base 1 are located inside the arm body 3. The fixed base 1 is straight and includes an outer base frame 11 and an inner base frame 12. The inner base frame 12 has a limiting step 121 and a limiting block 124. The outer base frame 11 has a locking part 111 that cooperates with the limiting step 121. The limiting block 124 abuts against the lower part of the base outer frame 11. The base outer frame 11 has a slot along its length. After the base inner frame 12 slides into the slot, the limiting step 121 limits the sliding of the base inner frame 12 within the slot and fixes it in place by the limiting block 124. The base outer frame 11 is made of metal and the base inner frame 12 is made of plastic, which effectively reduces the production cost of the base assembly and extends the service life of the fixed base 1 device. The front and rear parts of the arm body 3 are respectively provided with screw adjustment component 31 and eccentric adjustment component 32. The arm body 3 is movably connected to the base outer frame 11 through the screw adjustment component 31 and eccentric adjustment component 32.
[0030] like Figure 2-5As shown, the inner frame 12 of the base has a limiting step 121, and the outer frame 11 of the base has a locking part 111 that cooperates with the limiting step 121. The inner frame 12 of the base is provided with a first mounting hole 122 and a second mounting hole 123 along its length. The first mounting hole 122 is located below the through hole 33 of the arm body 3, and the second mounting hole 123 is located behind the tail of the arm body 3. Each of the first mounting hole 122 and the second mounting hole 123 is provided with an assembly screw 8, and the fixed base 1 is installed on the cabinet by the assembly screw 8.
[0031] like Figure 2-5 As shown, the base frame 11 has a sliding groove 112 and a positioning hole 113 along its length. The arm body 3 has a first adjustment hole 34 and a second adjustment hole 35 along its length. The first mounting hole 122 and the second mounting hole 123 eliminate the need for manual positioning. After measuring the installation position, the base 1 can be fixed in the installation position and installed directly. The screw adjustment component 31 is set in the first adjustment hole 34, passes through the first adjustment hole 34 and is slidably set in the sliding groove 112. The eccentric adjustment component 32 is set in the second adjustment hole 35. The eccentric adjustment component 32 includes a nut 321 and an eccentric rotating shaft 322 eccentrically set at the lower end of the nut 321. The nut 321 passes through the second adjustment hole 35 and the eccentric rotating shaft 322 is rotatably set in the positioning hole 113.
[0032] like Figure 6 As shown, the damping device 7 includes a support 71, a linkage 72, and a damping element 73. The support 71 is fixedly installed inside the arm body 3, the damping element 73 is slidably installed inside the support 71, and the linkage 72 is slidably installed on the support 71. The damping element 73 and the linkage 72 slide synchronously.
[0033] During adjustment, simply rotating the screw adjusting component 31 changes the height of the fixed base 1 and simultaneously alters the relative position of the screw adjusting component 31 and the slide groove 112, adjusting the horizontal vertical position of the fixed base 1. This allows for simultaneous adjustment of the hinge cup 2 cover position and door gap adjustment. Rotating the eccentric adjusting component 32 adjusts the horizontal front-to-back position of the fixed base 1. When deviations in the cabinet's openings prevent proper installation, compensatory adjustments can be made, avoiding the need for re-drilling due to opening deviations. The screw adjusting component 31 and the eccentric adjusting component 32 enable vertical and front-to-back position adjustment between the cabinet and the door. Users can adjust the relative position between the cabinet and the door according to their needs, effectively eliminating problems caused by inconsistent manufacturing specifications or misalignment during installation, which can lead to gaps between the furniture cabinet and doors, affecting usability and aesthetics. This greatly facilitates daily use.
[0034] Through the above structural improvements, users can quickly and conveniently lock and release the door and cabinet using a single-hinged hinge. The fixed base 1 of the single-hinged hinge is entirely in a straight line shape and has an eccentric adjustment component 32 positioned at the rear of the arm 3. This reduces the installation space requirement on the cabinet side panel to 40mm, and it can accommodate doors of any thickness from 16mm to 25mm. The arm 3 is shortened to 88mm, consistent with the length of a traditional four-hole base hinge, allowing for direct replacement. This effectively reduces the overall length of the fixed base 1 while making its appearance more aesthetically pleasing. The fixed base 1 is partially covered by the arm 3, effectively preventing user scratches or hinge detachment during use and improving product safety.
[0035] Of course, the above embodiments are only for illustrating the technical concept and features of this utility model, and their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All modifications made in accordance with the spirit and essence of the main technical solution of this utility model should be covered within the protection scope of this utility model.
