[0008] The adjusting member is an eccentric adjusting member, and is provided with an adjusting action portion for a tool or manual action; the coupling member is provided with a transmission portion; the tool or manual action acts on the adjusting action portion through the hinge avoidance portion and the notch portion in sequence, and drives the eccentric portion of the adjusting member to rotate on the rotating matching portion. When the adjusting member rotates, the transmission portion drives the coupling member to move relative to the fixed member to achieve position adjustment between the fixed member and the coupling member.

[0009] The connecting member is provided with connecting left and right bending parts on both sides respectively; the transmission part is provided on the inner side of the connecting left and right bending parts; the fixing member is provided with fixed left and right bending parts on both sides respectively; the adjusting member is located between the connecting left and right bending parts and the fixed left and right bending parts.

[0010] A guide shaft is also arranged transversely between the engaging left and right bending parts and the fixed left and right bending parts; the fixed part and the engaging part realize guided position adjustment through the cooperation of the adjusting part and the guide shaft.

[0012] A front elastic member is provided between the front locking member and the front end of the intermediate element. The front locking member slides at the front end of the intermediate element through the elastic limitation of the front elastic member and always generates a locking force toward the rear end of the intermediate element. When the front locking member slides, it elastically locks or disengages with the front locking position.

[0013] A rear elastic part is provided between the rear fastening part and the rear end of the intermediate element. The rear fastening part swings at the rear end of the intermediate element through elastic limitation of the rear elastic part, and always generates a fastening force toward the front end of the intermediate element.

[0014] The outer side of the engaging member or the fixing member is provided with a pre-positioning step and a final positioning portion; the intermediate element or the connecting arm is provided with a pre-positioning matching step and a final positioning matching portion.

[0015] The coupling or fixing part and the intermediate element or connecting arm are pre-positioned by the cooperation of the pre-positioning step and the pre-positioning matching step, and after the pre-positioning, at least the front and rear positioning are achieved by the cooperation of the final positioning part and the final positioning matching part, and after the front and rear positioning, a detachable connection is achieved by the cooperation of the front locking part and the front locking position, and the rear buckling part and the rear buckling position, so as to finally achieve a pre-positioned detachable matching connection between the hinge body and the fixed base.

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

[0017] 1. The fixing part and the coupling part are arranged in a straight line, and fixing parts are respectively provided at the front and rear positions of the fixing part, and a rotating matching part is provided in the middle part. The fixing part can be fixed by the two fixing parts, eliminating the disadvantage of the existing technology that the fixing base can only be fixed to the wall panel on the left and right sides, reducing the overall volume of the hinge, reducing the production cost, and making the hinge look more exquisite. At the same time, since the fixing part and the coupling part are in a straight line, the left and right parts of the existing technology are eliminated, and after the hinge is installed, the fixing part will be blocked by the connecting arm and / or the intermediate component, so the user cannot touch the fixing part when in use, further avoiding the safety hazards such as user scratches or hinge falling during the use of the hinge.

[0018] 2. The connecting arm and the intermediate element are provided with a hinge avoidance portion corresponding to the adjusting piece, and the joint piece is provided with a notch portion corresponding to the adjusting piece. The user can act on the adjusting piece through the hinge avoidance portion and the notch portion to achieve position adjustment between the fixing piece and the joint piece, making the use of the furniture hinge more convenient. At the same time, the adjusting piece is located in the middle position of the fixing piece, the joint piece, the connecting arm, and the intermediate element, which more reasonably utilizes the spatial dimensions of the fixed base and the hinge body, further reducing the overall volume of the furniture hinge, reducing production costs, and being more conducive to the integrated production of furniture hinges, thereby improving the compactness of the connection between the components.

[0019] 3. When assembling the coupling or fixing part and the intermediate element or connecting arm, pre-positioning is first achieved through the cooperation of the pre-positioning step and the pre-positioning matching step. Therefore, the coupling or fixing part and the intermediate element or connecting arm can be assembled at the specified position, thereby ensuring that the final positioning part and the final positioning matching part can complete the mutual positioning function, that is, after pre-positioning, the coupling or fixing part and the intermediate element or connecting arm can achieve at least front and rear positioning through the cooperation of the final positioning part and the final positioning matching part, thereby avoiding the problem that the positioning position of the final positioning part and the final positioning matching part deviates due to the front locking part and the front locking position, the rear buckle part and the rear buckle position cannot cooperate normally, or the cooperation is difficult, or the cooperation position is unreasonable, thereby affecting the positioning function of the two, so as to improve the assembly accuracy between the coupling or fixing part and the intermediate element or connecting arm.

[0020] 4. The front locking member always generates a locking force toward the rear end of the intermediate element through the action of the front elastic member, and is elastically locked or disengaged with the front locking position at the front end of the coupling member. The rear buckle member always generates a buckling force toward the front end of the intermediate element through the action of the rear elastic member, and is elastically buckled or disengaged with the rear buckle position at the rear end of the coupling member, thereby realizing a simple disassembly and assembly connection between the hinge body and the fixed base; since the front buckle member and the front locking member generate forces in opposite directions respectively, the fixed base can be effectively clamped and fixed in the front and back directions during assembly, thereby improving the assembly stability between the hinge body and the fixed base and making the assembly between the two more secure. At the same time, since the front buckle member and the front locking member can elastically move at the front and rear ends of the intermediate element, the problem of the hinge body and the fixed base being stuck after assembly can be effectively avoided, thereby improving the rationality of assembly between the hinge body and the fixed base, and at the same time, it is convenient for users to dismantle the hinge body and the fixed base, which greatly facilitates user use.

[0021] 5. Since the front buckle and the front locking parts can move flexibly at the front and rear ends of the intermediate element, and the hinge body can be assembled on the fixed base by pressing, the pressing force is applied quickly, conveniently, easily and with little force, thereby reducing the force used by the user when assembling the hinge body and the fixed base, making it more convenient for the user to use.

[0022] 6. During use, the user can use gradual pressing or direct pressing to complete the assembly between the hinge body and the fixed base according to actual needs; that is, the user can first assemble the front locking part and the front locking position, and then press and assemble the rear buckle part and the rear buckle position, or first assemble the rear buckle part and the rear buckle position, and then press and assemble the front locking part and the front locking position, or, at the same time, press and assemble the front locking part and the front locking position, and the rear buckle part and the rear buckle position. The choice of multiple pressing assembly sequences can further improve the user's convenience.

[0023] In general, it has the characteristics of simple and reasonable structure, flexible adjustment, low manufacturing cost, long service life, small space occupation, exquisite appearance, good concealment, safe and reliable use, and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
