[0029] Through the improvement of the above structure, the present invention has the following advantages compared with the prior art:

[0030] 1. A cover plate is disassembled and assembled on the connecting arm, and the cover plate can completely cover the connecting portion, the pressing member and the buckling member of the connecting arm, not only making the appearance of the furniture product more neat and beautiful, but also avoiding the exposure of the connecting parts such as the assembly part, the assembly fitting part, the buckling part, the buckling fitting part, and the fastener. When the user uses it, the above positions will not be accidentally touched, thus reducing the problems of furniture hinge dropping or user injury and improving the use safety; moreover, after the cover plate is assembled, it can realize the positioning of the front-back, left-right, and up-down positions, so its assembly stability is relatively high and it is not easy to loosen, thereby improving its use stability.

[0031] 2. By using the fastening effect of the fastener, the pressing member and the buckling member are fixed as a whole, not only improving the assembly stability of the two, but also using the elastic force of the elastic member to enable the pressing member and the buckling member to simultaneously slide linearly elastically on the extending portion. Since the pressing member and the buckling member are fixed as a whole, no matter how large the elastic force of the elastic member is, the separation of the pressing member and the buckling member will not be caused. On the basis of ensuring the stable assembly of the two, it is ensured that the elastic member can generate a large enough elastic force, so that a stable assembly can be realized between the furniture base and the hinge device, avoiding loosening problems.

[0032] 3. The left-right, up-down, and front-back position fixed assembly can be realized between the pressing member and the buckling member, further improving the assembly stability of the two and at the same time improving the connection compactness between the two; the pressing member and the buckling member can simultaneously slide with left-right and front-back position limits relative to the connecting plate, thereby reducing the shaking and swinging problems that occur when the pressing member and the buckling member slide, so as to improve the use stability of the pressing member and the buckling member.

[0033] 4. When in use, the user can pre-assemble the fixed base and the hinge device on the furniture cabinet body and the furniture door body respectively.

[0034] When the hinge device is assembled, the rear assembly part is pre-positioned and guided to be placed on the assembly mating notch through the assembly guiding part, and the front assembly mating part can also be pre-positioned and guided to be placed on the assembly notch through the assembly guiding part. Then, the hinge device is linearly slid and assembled on the front and rear assembly mating parts by using the front and rear assembly parts respectively. Subsequently, the buckling part and the buckling mating part are mutually guided and buckled through the buckling guiding part, so as to realize the all-round fixed connection between the hinge device and the fixed base in the left-right, up-down and front-back directions, and finally realize the quick disassembly and assembly between the furniture cabinet body and the furniture door body, making the disassembly and assembly between the two more convenient and fast, and more stable and firm after assembly.

[0035] Since the front assembly part and the rear assembly mating part can be pre-positioned and guided to be placed on the assembly mating notch and the assembly notch respectively, it is not only convenient for the user to pre-position and place the hinge device on the fixed base, avoiding the need for the user to align multiple times to make the hinge device and the fixed base in the correct assembly position, reducing the user's redundant operations and improving the assembly convenience of the user. At the same time, it can also effectively reduce the translational sliding assembly distance between the hinge device and the fixed base, enabling the user to assemble the hinge device on the fixed base within a limited space position, so that the user can set multiple hinge devices on the furniture door body, and the multiple hinge devices can be assembled on the fixed base asynchronously, improving the assembly convenience of the user.

[0036] At the same time, the buckling part and the buckling mating part can realize guided buckling, enabling the user to apply less linear sliding force to realize the buckling between the buckling part and the buckling mating part, further improving the assembly convenience of the user.

[0037] When the hinge device is disassembled, only by applying a tool or manually acting on the pressing part, the buckling part and the buckling mating part are separated from each other, and then the front and rear assembly parts are linearly slid away from the front and rear assembly mating parts respectively, so as to realize the disassembly between the hinge device and the fixed base. During the whole process, when the front assembly part slides to a certain position, it will limit the rear assembly mating part, not only prompting the user that the disassembly of the hinge device has been completed, but also avoiding the problem that the hinge device slides out excessively, resulting in the user being injured or the furniture door body falling from the user's hand, improving the use safety of the user.

[0038] Moreover, the pressing of the pressing part is a downward linear operation, and its operation process is convenient and fast. Compared with the swinging or rotating of the prior art (the user needs to apply a swinging or rotating force in addition to the pressing force), the user only needs to apply a single pressing force, and it is easier to apply.

[0039] 5. Due to the positioning and mating relationships between the front assembly part and the front assembly mating part, the rear assembly part and the rear assembly mating part, and the snap joint part and the snap joint part, the hinge device can be prevented from detaching from the fixed base when subjected to forces in different directions after assembly, resulting in a higher structural strength and stronger load-bearing capacity of the hinge device. This not only avoids potential safety hazards such as breakage and deformation during use, which could cause the furniture door to fall, but also further improves the assembly stability between the fixed base and the hinge device, extends the service life of the hinge device, and can be widely applied to furniture doors with large volume and weight.

[0040] 6. The pressing part and the snap joint part can linearly and elastically slide on the extension part, and the direction is different from the direction of the sliding disassembly and assembly of the hinge device. This not only enables the snap joint mating part to generate reaction forces in different directions compared to the disassembly of the hinge device after the hinge device and the fixed base are assembled, so that the hinge device can be stably assembled on the fixed base, but also facilitates the user to apply a linear pressing force to the pressing part and the snap joint part, improving the convenience of disassembling the hinge device from the fixed base.

[0041] Generally speaking, it has the characteristics of reasonable structure, compact connection between components, low manufacturing cost, easy production, easy implementation, wide application range, fast, simple and convenient disassembly and assembly process, and firm assembly, with strong practicability.
