[0016] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0017] 1. The U-shaped front and rear ends of the intermediate element are elastically movable with a locking member and a buckle member, respectively. The locking member always generates a locking force toward the rear end of the connecting arm or the intermediate element through the action of the front elastic member, and is elastically locked or disengaged with the front opening of the front end of the base. The buckle member always generates a buckling force toward the front end of the connecting arm or the intermediate element through the action of the rear elastic member, and is elastically buckled or disengaged with the rear buckling part of the rear end of the base, so that the connecting arm, the intermediate element and the base can be easily disassembled and connected; because the buckle member and the locking member generate forces in opposite directions respectively, the base can be effectively clamped and fixed in the front and rear directions during assembly, thereby improving the assembly stability between the connecting arm, the intermediate element and the base, making the assembly between the connecting arm, the intermediate element and the base more secure, and at the same time, because the buckle member and the locking member can be elastically movable at the front and rear ends of the intermediate element, the problem of the connecting arm, the intermediate element and the base being stuck after assembly can be effectively avoided, thereby improving the rationality of the assembly between the connecting arm, the intermediate element and the base, and at the same time, it is convenient for users to dismantle the connecting arm, the intermediate element and the base, which greatly facilitates the use of users.

[0018] 2. The connecting arm is provided with a first step portion, a second step portion and a notch portion, and the front elastic member is U-shaped and is provided with a first action portion, a second action portion, a bending portion and a locking action portion. During assembly, the front elastic member acts on the first step portion by elastic positioning in the left and right and / or front and back manner through the first action portion, the bending portion is positioned up and down on the notch portion, and the front elastic member acts on the second step portion by the second action portion in a winding manner, that is, the left and right, front and back, and up and down positioning of the front elastic member can be achieved, which can effectively improve the assembly firmness of the front elastic member.

[0019] 3. Since the front elastic member is at least partially wound around the second step portion, the elastic force of the front elastic member can be converted so that the first action portion and the locking action portion can always generate an action force toward the rear end of the connecting arm or the intermediate element at the same time, thereby enhancing the elastic force of the front elastic member and making the elastic force generated by the front elastic member more concentrated, ultimately preventing the base from detaching from the connecting arm or the intermediate element during daily use, thereby improving the assembly stability and firmness between them.

[0020] 4. A positioning portion and a positioning matching portion for mutual positioning and cooperation are respectively provided between the base and the intermediate element. After the base and the intermediate element are buckled and locked with each other, left-right, and / or front-back, and / or up-and-down positioning can be achieved through the cooperation of the positioning portion and the positioning matching portion, thereby further improving the assembly stability between the base and the intermediate element and avoiding the problem of the two being loose when hinged and opened.

[0021] 5. Guide positions are respectively provided between the opening buckle part and the rear buckle part, between the locking piece and the front opening part, and between the positioning part and the positioning matching part. The user only needs to press force during assembly to achieve the matching between the opening buckle part and the rear buckle part, between the locking piece and the front opening part, and between the positioning part and the positioning matching part through the guiding effect of the guide position. The application of the pressing force is quick, convenient, easy and of small force, thereby reducing the force used by the user when assembling the connecting arm, the intermediate element and the base, and further facilitating the use of the user; at the same time, the user can assemble the opening buckle part and the rear buckle part first, and then press and assemble the locking piece and the front opening part according to actual needs during use, or assemble the locking piece and the front opening part first, and then press and assemble the opening buckle part and the rear buckle part, or press and assemble the opening buckle part and the rear buckle part, and the locking piece and the front opening part at the same time. The selection of multiple assembly sequences can further improve the convenience of user use.

[0022] 6. The intermediate components are provided with limiting parts corresponding to the elastic activities of the buckles and locking parts. When in use, users can predict the elastic activity positions of the buckles and locking parts through the limiting parts to improve the user experience and avoid the problem of excessive activities of the buckles and locking parts affecting the stability of furniture hinges.

[0023] 7. An up-and-down adjustment member and / or a front-and-back adjustment member are also provided between the connecting arm and the middle element. The user can adjust the up-and-down and / or front-and-back relative position between the connecting arm and the middle element through the up-and-down adjustment member and / or the front-and-back adjustment member according to actual use requirements, thereby effectively improving the overall aesthetics of the furniture hinge while also improving the compactness of the connection between the components.

[0024] In general, it has the characteristics of simple and reasonable structure, reliable performance, low manufacturing cost, long service life, easy production, easy implementation, exquisite appearance, firm assembly, high safety, and fast, simple and convenient disassembly and assembly process, and is highly practical.
