[0023] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0024] Example 1 See Figures 1 to 4 This application provides a hinge quick-release structure, including a hinge cup, a hinge arm, an adjusting arm 1, and a base 2. The hinge arm is rotatably connected to the hinge cup; the adjusting arm 1 is movably installed inside the hinge arm; the hinge cup is installed on a cabinet door; and the base 2 is installed on a cabinet body. The adjusting arm 1 has a first end and a second end, and the base 2 has a third end corresponding to the first end of the adjusting arm 1 and a fourth end corresponding to the second end of the adjusting arm 1. The first end of the adjusting arm 1 and the third end of the base 2 are detachably connected via a first elastic snap-fit ​​structure, and the second end of the adjusting arm 1 and the fourth end of the base 2 are detachably connected via a second elastic snap-fit ​​structure.

[0025] In this embodiment, the first end and the second end of the adjusting arm 1 are the front end and the rear end of the adjusting arm 1, respectively; similarly, the third end and the fourth end of the base 2 are the front end and the rear end of the base 2, respectively; the front end of the adjusting arm 1 and the front end of the base 2 are detachably connected by a first elastic snap-fit ​​structure, and the rear end of the adjusting arm 1 and the rear end of the base 2 are detachably connected by a second elastic snap-fit ​​structure.

[0026] With this configuration, when installing the adjusting arm 1 and the base 2, the front end of the adjusting arm 1 can be first snapped into the front end of the base 2, and then the rear end of the adjusting arm 1 can be connected to the rear end of the base 2 to complete the assembly; alternatively, the rear end of the adjusting arm 1 can be first snapped into the rear end of the base 2, and then the front end of the adjusting arm 1 can be snapped into the front end of the base 2 to complete the assembly; or the front end of the adjusting arm 1 and the front end of the base 2, as well as the rear end of the adjusting arm 1 and the rear end of the base 2, can be snapped into simultaneously to complete the assembly. Therefore, the adjusting arm 1 and the base 2 can be installed in multiple ways, greatly improving the installation convenience for installers.

[0027] Specifically, the first elastic snap-fit ​​structure includes a first snap hook 101 disposed on both sides of the front end of the adjusting arm 1 and a first spring piece 3 disposed at the front end of the base 2. The first snap hook 101 is detachably snapped onto the front edge of the first spring piece 3.

[0028] Therefore, when it is necessary to engage the front end of the adjusting arm 1 with the front end of the base 2, simply press the front end of the adjusting arm 1 from top to bottom to drive the first hook 101 to abut against and pass over the first spring 3 and finally hook it onto the front edge of the first spring 3 to achieve assembly. The operation is simple.

[0029] In this embodiment, the first hook 101 is integrally formed on the adjusting arm 1; the first spring piece 3 is riveted and fixed to the base 2 by the first rivet 4.

[0030] Furthermore, the second elastic snap-fit ​​structure includes a snap-fit ​​member 5 hinged to the rear end of the adjusting arm 1. A torsion spring 6 is provided at the hinge point between the snap-fit ​​member 5 and the adjusting arm 1. A second hook 501 is provided on the snap-fit ​​member 5. The second hook 501 can be detachably snapped to the rear end of the base 2 under the elastic force of the torsion spring 6.

[0031] Therefore, when it is necessary to snap the rear end of the adjusting arm 1 to the rear end of the base 2, simply press the rear end of the adjusting arm 1 from top to bottom to drive the second hook 501 to abut against and pass over the rear end edge of the base 2 and finally hook it onto the rear end edge of the base 2 to achieve assembly. The operation is simple.

[0032] In addition, the buckle 5 is also provided with an integrally formed pressing part 503. When it is necessary to separate the rear end of the adjusting arm 1 from the rear end of the base 2, the second hook 501 on the buckle 5 can be driven to disengage from the rear end of the base 2 by pressing the pressing part 503, and then the rear end of the base 2 can be removed. Then the front end of the adjusting arm 1 can be separated from the front end of the base 2 to achieve separation between the two.

[0033] The system also includes a pin 7. Second shaft holes 102 are provided on both sides of the rear end of the adjusting arm 1, and third shaft holes 502 are provided on both sides of the fastener 5. The pin 7 passes through the second shaft holes 102 and the third shaft holes 502 respectively to hinge the fastener 5 to the adjusting arm 1. A torsion spring 6 is sleeved on the pin 7, with both ends of the torsion spring 6 abutting against the rear end of the adjusting arm 1, and the middle part of the torsion spring 6 abutting against the fastener 5, thus providing elastic force to the fastener 5.

[0034] In addition, to improve the stability of the connection between the adjusting arm 1 and the base 2, this application also provides a limiting structure between the adjusting arm 1 and the base 2. Specifically, the limiting structure includes a limiting hole 2023 opened on the base 2 and a limiting block 103 provided at the bottom of both ends of the adjusting arm 1 and engaging with the limiting hole 2023. When the front and rear ends of the adjusting arm 1 are respectively engaged and fixed with the front and rear ends of the base 2, the limiting block 103 is just inserted into the limiting hole 2023, thereby improving the stability between the two.

[0035] Of course, in other embodiments, the positions of the limiting hole 2023 and the limiting block 103 can be interchanged to achieve the same technical effect, and there are no restrictions on this.

[0036] See also Figure 4 The base 2 includes a fixed frame 201 and a movable frame 202 slidably disposed on the fixed frame 201. The first spring piece 3 is installed at the bottom of the movable frame 202 by a first rivet 4 and its front end extends out of the front end of the base 2 to be engaged and fixed with the first hook 101 on the adjusting arm 1. The second hook 501 on the buckle 5 is engaged and fixed with the rear end of the movable frame 202.

[0037] The system also includes an adjusting pin 8. The movable frame 202 has an adjusting hole 2021, and the fixed frame 201 has a fixed hole 2011. The adjusting pin 8 passes through the adjusting hole 2021 and is rotatably fixed in the fixed hole 2011, and the side wall of the adjusting pin 8 abuts against the hole wall of the adjusting hole 2021. Thus, when the adjusting pin 8 is rotated, the movable frame 202 can be moved along the width direction of the fixed frame 201 through its abutment with the adjusting hole 2021.

[0038] In addition, the fixed bracket 201 is provided with mounting holes 2012 for fixing to the cabinet, and the movable bracket 202 is provided with clearance holes 2022 that communicate with the mounting holes 2012. Thus, assembly can be completed by passing screws through the clearance holes 2022 and the mounting holes 2012 and driving the mounting holes 2012 to fix them to the cabinet. Example 2 See Figures 5 to 8 The difference between the hinge quick-release structure in this embodiment and that in Embodiment 1 is that the first elastic snap-fit ​​structure is different. In this embodiment, the first elastic snap-fit ​​structure includes a snap-fit ​​shaft 9 disposed at the front end of the adjusting arm 1 and a second spring piece 10 disposed at the front end of the base 2. The second spring piece 10 has a snap-fit ​​hole 1001, and the snap-fit ​​shaft 9 can be detachably snapped into the snap-fit ​​hole 1001.

[0039] Therefore, when it is necessary to snap the front end of the adjusting arm 1 to the front end of the base 2, simply press the front end of the adjusting arm 1 from top to bottom to drive the snap shaft 9 to snap into the snap hole 1001 to achieve assembly. The operation is simple.

[0040] The adjusting arm 1 has first shaft holes 104 through both sides of its front end, and the retaining shaft 9 passes through the two first shaft holes 104; the front end of the second spring piece 10 is bent upward to form a retaining hole 1001; the second spring piece 10 is riveted and fixed to the bottom of the moving frame 202 by the second rivet 11.

[0041] In summary, this utility model has the following technical effects: The buffer hinge of this utility model has a first elastic snap-fit ​​structure that allows for a detachable connection between the first end of the adjusting arm 1 and the third end of the base 2, and a second elastic snap-fit ​​structure that allows for a detachable connection between the second end of the adjusting arm 1 and the fourth end of the base 2. With this configuration, when it is necessary to install the adjusting arm 1 and the base 2, the first end of the adjusting arm 1 can be snapped to the third end of the base 2 first, and then the second end of the adjusting arm 1 can be snapped to the fourth end of the base 2 to achieve assembly; alternatively, the second end of the adjusting arm 1 can be snapped to the fourth end of the base 2 first, and then the first end of the adjusting arm 1 can be snapped to the third end of the base 2 to achieve assembly; or the first end of the adjusting arm 1 and the third end of the base 2, as well as the second end of the adjusting arm 1 and the fourth end of the base 2, can be snapped to achieve assembly simultaneously. Therefore, the adjusting arm 1 and the base 2 can be installed in multiple ways, greatly improving the installation convenience for installers.

[0042] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
