Description

Technical Field

[0001] This application belongs to the field of hinge technology, and in particular relates to quick-release hinges. Background Technology

[0002] Hinges are widely used in furniture doors, equipment covers, and other structures. A typical hinge structure includes a hinge cup, a hinge arm, and a mounting base. The mounting base is directly mounted to the external structure with screws, and the hinge arm connects to the mounting base to achieve the opening and closing action.

[0003] However, there are significant inconveniences in the actual installation and disassembly of hinges. Assemblers must rely on tools to tighten and loosen screws when fixing or replacing hinges, involving numerous steps and considerable time consumption. Furthermore, when the external structure is made of wood, repeated screw installation and removal can easily cause the original mounting holes to gradually enlarge or become damaged, reducing the engagement force of subsequent screws and thus affecting the stability and reliability of the connection.

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention

[0005] This application provides a quick-release hinge to solve or alleviate one or more technical problems in the prior art.

[0006] The first aspect of this application provides a quick-release hinge, including: Hinge cup, used for fixed connection with the first external structure; The hinge arm has one end rotatably connected to the hinge cup and the other end rotatably connected to the fixed base; A fixed base is used for fixed connection with a second external structure. The fixed base includes an upper housing and a lower housing. The upper housing is used for rotatable connection with the hinge arm. A first limiting shaft is spanned between two opposing first sidewalls of the upper housing. The lower housing is provided with a first hook groove for engaging with the first limiting shaft. The quick-release assembly includes a pressing plate and an elastic element. One end of the pressing plate is rotatably connected to the lower housing. The pressing plate is also provided with a limiting protrusion. The elastic element is fixed to the lower housing and abuts against the pressing plate to push the pressing plate upward. When the first limiting shaft is engaged in the first hook groove and the pressing plate is pushed upward by the elastic member, the limiting protrusion cooperates with the first hook groove to form a first limiting groove. The opening of the first limiting groove is smaller than the diameter of the first limiting shaft, so as to lock the first limiting shaft in the first limiting groove, so as to fix the upper housing and the lower housing in a fixed connection.

[0007] Optionally, the lower housing includes a lower chassis and two opposing second sidewalls, the two second sidewalls being fixed to the same side of the lower chassis, and each of the two second sidewalls having a first protrusion on the side closest to each other, the first protrusion being used to block the pressing plate.

[0008] Optionally, the lower housing further includes a second limiting shaft and a third limiting shaft, both of which are connected across the two second side walls, and one end of the pressing plate is rotatably sleeved on the third limiting shaft; The elastic element includes a sleeve portion, a first extension end, and a second extension end. The first extension end and the second extension end are respectively connected to opposite sides of the sleeve portion. The sleeve portion is sleeved on the third limiting shaft. The first extension end abuts against the bottom of the second limiting shaft, and the second extension end abuts against the bottom of the pressing plate.

[0009] Optionally, the upper housing includes an upper chassis and two opposing first sidewalls, the two first sidewalls being fixed to the same side of the upper chassis, and the upper chassis and the two opposing first sidewalls cooperating to form a groove for accommodating the lower housing.

[0010] Optionally, the upper chassis includes a first upper plate and a second upper plate, wherein the first upper plate is stacked and fixed on the second upper plate; The quick-release hinge also includes a first adjustment component, which is disposed on the first upper plate and the second upper plate. The first adjustment component is axially rotatable, and the rotation of the first adjustment component can cause the first upper plate to move relative to the second upper plate in a first direction.

[0011] Optionally, the quick-release hinge further includes a second adjustment component. The first adjustment component passes through the first upper plate and is fixed to the second upper plate. The second adjustment component is axially rotatable, and the axial rotation of the second adjustment component can cause the first upper plate and the second upper plate to move closer to or further apart from each other.

[0012] Optionally, the second sidewall of the lower housing is further provided with a second hook groove at the end away from the lower chassis, and the second hook groove is spaced apart from the first hook groove; The first sidewalls of the upper housing are each provided with a second protrusion that matches the second hook groove on the side that is close to each other; In the case where the upper housing and the lower housing are fixedly connected, the second hook groove is hooked to the second protrusion.

[0013] Optionally, the lower chassis includes a first lower chassis and a second lower chassis, the first lower chassis being stacked on the second lower chassis, and the opposite ends of the first lower chassis being fastened to the second lower chassis; The quick-release hinge also includes a third adjustment component, which is inserted through the first lower plate and the second lower plate. The third adjustment component is axially rotatable, and the rotation of the third adjustment component can cause the first lower plate to move relative to the second lower plate in a second direction.

[0014] Optionally, the hinge cup includes a cup plate, a cup rim, and a pull plate. The cup rim is fixed to one side of the cup plate and forms a receiving groove for accommodating part of the hinge arm. The pull plate is slidably attached to the cup plate. The quick-release hinge also includes a damping mechanism, the two ends of which abut against the rim of the cup and the pull plate, respectively; When the hinge arm rotates relative to the hinge cup, the hinge arm drives the pull plate to move, thereby causing the pull plate to compress the damping mechanism and generate a damping force.

[0015] Optionally, a rotating shaft is bridging the receiving groove, and the hinge arm is rotatably connected to the rotating shaft; The quick-release hinge also includes a damping adjustment block, which is slidably sleeved on the rotating shaft. One end of the damping adjustment block is connected to the hinge arm so that the damping adjustment block can rotate synchronously with the hinge arm. A first damping block and a second damping block are fixed on the pull plate; When the damping adjustment block slides to the first position along the rotation axis, the damping adjustment block is disposed opposite to the first damping stop block. When the hinge arm rotates at a first predetermined angle, the damping adjustment block contacts the first damping stop block so that the hinge arm drives the pull plate to move. When the damping adjustment block slides to the second position along the rotation axis, the damping adjustment block is positioned opposite to the second damping stop. When the hinge arm rotates to the second predetermined angle, the damping adjustment block contacts the second damping stop, so that the hinge arm drives the pull plate to move.

[0016] The embodiments of this application employing the above-described technical solution may have the following advantages: When installing the upper and lower housings, first press the pressing plate to expose the entire first hook groove, facilitating the entry of the first limiting shaft. After the first limiting shaft enters the first hook groove, the pressing plate can be released. The elastic element then pushes the pressing plate upwards, causing the limiting protrusion of the pressing plate to block part of the opening of the first hook groove, thus forming the first limiting groove and locking the first limiting shaft within it, completing the installation. If the hinge needs to be disassembled, simply press down the pressing plate to separate the upper and lower housings. The lower housing can remain on the first external structure without requiring further screw removal. This not only reduces the cumbersome screw handling steps in traditional hinge disassembly and assembly, significantly improving efficiency, but also avoids the enlargement or damage to the original mounting holes caused by repeated screw removal and assembly, thus ensuring the long-term stability of the external structure.

[0026] This application provides a quick-release hinge. Based on this, the hinge can be quickly installed or removed, and the problem of gradually enlarging or damaging the mounting holes can be mitigated in the event of repeated installation and removal. See below for details.

[0027] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0028] Please see Figures 1 to 7 This application provides a quick-release hinge, which includes a hinge cup 10, a hinge arm 20, a fixing base 30, and a quick-release assembly. The following is a detailed description: The hinge cup 10 is used for fixed connection with the first external structure. The first external structure can be a door panel or a cover plate, and the hinge cup 10 can be fixed to the first external structure by screws or an embedded structure.

[0029] One end of the hinge arm 20 is rotatably connected to the hinge cup 10, and the other end is rotatably connected to the fixed base 30. Through the rotatable connection at both ends of the hinge arm 20, smooth opening and closing of the door panel relative to the fixed base 30 can be achieved. In some embodiments, a pin structure or a pivot assembly can be used to ensure good smoothness of the hinge arm 20 in terms of opening angle and closing springback.

[0030] The fixing base 30 is used for fixed connection with the second external structure. The fixing base 30 includes an upper shell and a lower shell. The upper shell is used for rotatable connection with the hinge arm 20. A first limiting shaft 312 is spanned between two opposing first side walls of the upper shell. The lower shell is provided with a first hook groove 351 for engaging with the first limiting shaft 312. Specifically, the second external structure can be a cabinet or a wall.

[0031] The quick-release assembly includes a pressing plate 42 and an elastic element 41. One end of the pressing plate 42 is rotatably connected to the lower housing. The pressing plate 42 is also provided with a limiting protrusion 421. The elastic element 41 is fixed to the lower housing and abuts against the pressing plate 42 to push the pressing plate 42 upward.

[0032] When the first limiting shaft 312 is engaged in the first hook groove 351 and the pressing plate 42 is pushed upward by the elastic member 41, the limiting protrusion 421 cooperates with the first hook groove 351 to form a first limiting groove. The opening of the first limiting groove is smaller than the diameter of the first limiting shaft 312, so as to lock the first limiting shaft 312 in the first limiting groove, so as to fix the upper shell and the lower shell in a fixed connection.

[0033] In practical applications, when the upper and lower housings are connected and fixed, the first limiting shaft 312 enters the locking position of the first hook groove 351, enabling rapid positioning. This means the first hook groove 351 can be initially fixed without screws. The pressing plate 42 can swing around a rotation point at one end of the lower housing. When installing the upper and lower housings, the pressing plate 42 can be pressed first to expose the entire first hook groove 351, facilitating the entry of the first limiting shaft 312. After the first limiting shaft 312 enters the first hook groove 351, the pressing plate 42 can be released. The elastic element 41 then pushes the pressing plate 42 upwards, causing the limiting protrusion 421 of the pressing plate 42 to block part of the opening of the first hook groove 351, forming a first limiting groove and locking the first limiting shaft 312 within the first hook groove 351. If the hinge needs to be disassembled, simply press down the pressing plate 42 to separate the upper and lower housings. The lower housing can remain on the first external structure without further screw removal. This not only reduces the tedious screw handling steps in traditional hinge assembly and disassembly, significantly improving assembly and disassembly efficiency, but also avoids the enlargement or damage of the original mounting holes caused by repeated screw assembly and disassembly, thus ensuring the long-term stability of the external structure.

[0034] In this embodiment, the lower housing includes a lower base 357 and two opposing second sidewalls. The two second sidewalls are fixed to the same side of the lower base 357. Each of the two second sidewalls has a first protrusion 353 on the side that is close to each other. The first protrusion 353 is used to block the pressing plate 42.

[0035] Specifically, the lower chassis 357 can be a single metal stamped part, serving as the load-bearing base for the lower housing. Two second sidewalls extend vertically from the same side, providing lateral restraint and support for the quick-release assembly and the upper housing. A first protrusion 353 located on one side of the sidewalls that is close to each other can provide a mechanical stop when the press plate 42 is pushed upward by the elastic member 41, thereby limiting the press plate 42 to a specific position to prevent the press plate 42 from being excessively lifted, which would cause the first limiting shaft 312 to be pushed out of the first hook groove 351.

[0036] Furthermore, in this embodiment, the lower housing also includes a second limiting shaft 354 and a third limiting shaft 355, both of which are connected across the two second side walls, and one end of the pressing plate 42 is rotatably sleeved on the third limiting shaft 355.

[0037] The elastic element 41 includes a sleeve portion 410, a first extension end 411, and a second extension end 412. The first extension end 411 and the second extension end 412 are respectively connected to opposite sides of the sleeve portion 410. The sleeve portion 410 is sleeved on the third limiting shaft 355. The first extension end 411 abuts against the bottom of the second limiting shaft 354, and the second extension end 412 abuts against the bottom of the pressing plate 42.

[0038] The second limiting shaft 354 and the third limiting shaft 355 together form the mounting reference for the pressing plate 42 and the elastic element 41. The third limiting shaft 355 serves as the rotation shaft 113 of the pressing plate 42, enabling the pressing plate 42 to achieve stable pressing and resetting actions around the shaft. The second limiting shaft 354 serves as the force support point for the elastic element 41, ensuring that the elastic element 41 maintains a fixed force direction during pressing and rebound.

[0039] In practical applications, the elastic element 41 is rotatably sleeved on the third limiting shaft 355 through the sleeve part 410, so that it remains structurally stable; the first extension end 411 contacts the second limiting shaft 354 and the second extension end 412 contacts the pressing plate 42, so that the pressing plate 42 undergoes elastic deformation when it is pressed down, and provides a rebound force after being released, automatically pushing the pressing plate 42 back to the top position, realizing the self-resetting locking function of the quick-release component.

[0040] In an optional embodiment, the upper housing includes an upper chassis 315 and two opposing first sidewalls, the two first sidewalls being fixed to the same side of the upper chassis 315, and the upper chassis 315 and the two opposing first sidewalls cooperating to form a groove for receiving the lower housing.

[0041] Specifically, one end of the upper housing is provided with an opening, which is connected to the sliding groove of the upper housing. When installing the upper housing and the lower housing, the opening of the upper housing can be aligned with the end of the lower housing, and then the lower housing can be slid into the upper sliding groove along the opening. The installation is then completed by locking the first limiting shaft 312.

[0042] Furthermore, the upper chassis 315 includes a first upper chassis 316 and a second upper chassis 317, wherein the first upper chassis 316 is stacked and fixed on the second upper chassis 317.

[0043] The quick-release hinge also includes a first adjustment component 51, which is inserted through the first upper plate 316 and the second upper plate 317. The first adjustment component 51 is axially rotatable, and the rotation of the first adjustment component 51 can drive the first upper plate 316 to move relative to the second upper plate 317 in a first direction.

[0044] Specifically, the first adjustment component 51 can be an eccentric bolt, which can be rotated to adjust the relative position of the first upper plate 316 and the second upper plate 317, thereby adjusting the tilt of the door or the gap width between the door and the cabinet.

[0045] In an optional embodiment, the quick-release hinge further includes a second adjustment component 52. The first adjustment component 51 passes through the first upper plate 316 and is fixed to the second upper plate 317. The second adjustment component 52 is axially rotatable, which allows the first upper plate 316 and the second upper plate 317 to move closer or further apart. The lifting height of the door relative to the cabinet can be adjusted by rotating the second adjustment component 52, thereby optimizing the installation details of the door by adjusting the hinge.

[0046] In an optional embodiment, the second sidewall of the lower housing is further provided with a second hook groove 356 at the end away from the lower chassis 357, and the second hook groove 356 is spaced apart from the first hook groove 351.

[0047] The first sidewalls of the upper housing are provided with a second protrusion (not shown) that matches the second hook groove 356 on the side that are close to each other. When the upper housing and the lower housing are fixedly connected, the second hook groove 356 is hooked to the second protrusion.

[0048] By engaging the second hook groove 356 with the second protrusion, the upper housing can be double-fixed when installed onto the lower housing: not only does the positioning shaft lock the first hook groove 351, but the engagement of the second hook groove 356 with the second protrusion further stabilizes the connection structure, enhancing the positioning accuracy and stability of the lower housing on the upper housing during quick-release operations, reducing the risk of accidental loosening, and improving the overall reliability of the quick-release hinge under load or frequent operation conditions.

[0049] Furthermore, the lower chassis 357 includes a first lower chassis 358 and a second lower chassis 359, with the first lower chassis 358 stacked on the second lower chassis 359, and the opposite ends of the first lower chassis 358 fastened to the second lower chassis 359.

[0050] The quick-release hinge also includes a third adjustment component 53, which is inserted through the first lower plate 358 and the second lower plate 359. The third adjustment component 53 is axially rotatable, and the rotation of the third adjustment component 53 can drive the first lower plate 358 to move relative to the second lower plate 359 in a second direction.

[0051] Specifically, the third adjusting component 53 can also be an eccentric bolt, and the second direction can be located on the same horizontal plane as the first direction, and the second direction and the first direction are perpendicular to each other.

[0052] Accordingly, the relative positions of the first lower plate 358 and the second lower plate 359 can be adjusted by rotating the third adjustment component 53, thereby adjusting the tilt of the door or the gap width between the door and the cabinet, so as to optimize the installation details of the door by adjusting the hinges.

[0053] In an optional embodiment, the hinge cup 10 includes a cup plate 11, a cup rim 12, and a pull plate 13. The cup rim 12 is fixed to one side of the cup plate 11 and forms a receiving groove for accommodating a portion of the hinge arm 20. The pull plate 13 is slidably attached to the cup plate 11. The quick-release hinge also includes a damping mechanism 60, with its two ends abutting against the cup rim 12 and the pull plate 13, respectively.

[0054] When the hinge arm 20 rotates relative to the hinge cup 10, the hinge arm 20 drives the pull plate 13 to move, thereby causing the pull plate 13 to press the damping mechanism 60 to generate a damping force.

[0055] Specifically, an abutment structure can be provided at the end of the pull plate 13. When the hinge arm 20 rotates to a certain angle, it abuts against the abutment structure, thereby driving the pull plate 13 to move and generate damping force. This allows the door to generate damping force only after rotating to a certain angle, rather than having a damping sensation at all times.

[0056] Furthermore, in this embodiment, a rotating shaft 113 is bridging within the receiving groove, and the hinge arm 20 is rotatably connected to the rotating shaft 113. The quick-release hinge also includes a damping adjustment block 115, which is slidably sleeved on the rotating shaft 113. One end of the damping adjustment block 115 is connected to the hinge arm 20, so that the damping adjustment block 115 can rotate synchronously with the hinge arm 20. A first damping stop 131 and a second damping stop 132 are fixed on the pull plate 13, and the second damping stop 132 has a different height than the first damping stop 131.

[0057] When the damping adjustment block 115 slides to the first position along the rotation axis 113, the damping adjustment block 115 is disposed opposite to the first damping stop block 131. When the hinge arm 20 rotates at a first predetermined angle, the damping adjustment block 115 contacts the first damping stop block 131, so that the hinge arm 20 drives the pull plate 13 to move.

[0058] When the damping adjustment block 115 slides to the second position along the rotation axis 113, the damping adjustment block 115 is disposed opposite to the second damping stop block 132. When the hinge arm 20 rotates to the second predetermined angle, the damping adjustment block 115 contacts the second damping stop block 132, so that the hinge arm 20 drives the pull plate 13 to move.

[0059] In this embodiment, the rotation angle of the hinge arm 20 when damping is triggered can be adjusted by moving the damping adjustment block 115. For example, when the damping adjustment block 115 slides along the rotation axis 113 to the first position, and the hinge arm 20 rotates 150°, the damping adjustment block 115 contacts the first damping stop 131, causing the hinge arm 20 to drive the pull plate 13 to move and generate damping force. When the damping adjustment block 115 slides along the rotation axis 113 to the second position, because the second damping stop 132 and the first damping stop 131 have different heights, when the hinge arm 20 rotates 100°, the damping adjustment block 115 contacts the second damping stop 132, causing the hinge arm 20 to drive the pull plate 13 to move and generate damping force.

[0060] That is, by moving the damping adjustment block 115, the door can generate damping force at different opening and closing degrees, and the user can adjust the opening and closing angle that triggers the damping according to their needs. In other embodiments, a number of other damping blocks of different heights can also be fixed on the pull plate 13, thereby increasing the number of selectable angles for the hinge to generate damping force.

[0061] In this embodiment, the cup plate is also provided with a top block, which is used to abut against the pull plate and to limit the farthest distance that the damping mechanism pushes the pull plate out.

[0062] In some embodiments, a through hole is provided at the end of the cup rim near the cup plate, which allows the pull plate to extend out, thereby improving the range of motion and flexibility of the pull plate.

[0063] In one optional embodiment, the hinge cup is provided with a first fixing hole, through which bolts, screws, or the like can be passed to fix the hinge cup to the first external structure. Specifically, the hinge cup may further include a cup edge, which is provided along the periphery of the cup edge, and the first fixing hole may be provided on the cup edge.

[0064] The lower housing is provided with a second fixing hole, and accordingly, the hinge cup can be fixedly connected to the second external structure by passing bolts, screws, etc. through the second fixing hole.

[0065] Furthermore, the pressing plate is provided with clearance holes, which are corresponding to the second fixing holes, so that the user can pass a screwdriver through the clearance holes on the pressing plate to tighten / loosen the bolts, reducing interference and reducing the volume occupied by the fixing base.

[0066] In an optional embodiment, the quick-release hinge further includes a cover plate assembly for covering the surfaces of the hinge cup and the mounting base to conceal the first and second mounting holes. The cover plate assembly may include a first cover plate and a second cover plate. The first cover plate covers the surface of the hinge cup, and the second cover plate covers the surface of the mounting base, thereby reducing dust accumulation, making the surfaces smooth and aesthetically pleasing.

[0067] In some embodiments, a connecting arm may be provided on the upper housing for rotatable connection with the hinge arm.
