Description

Invisible hinge

Technical Field

The utility model relates to the technical field of hinges, in particular to an invisible hinge.

Background

At present, for the sake of beauty, hidden hinges are increasingly used in door leaf installation, and hidden hinges with an automatic closing function for controlling the closing speed by hydraulic pressure are also becoming popular, but the adjustment of the closing speed by hydraulic pressure after installation is extremely inconvenient.

The existing concealed hinge has the advantages that the adjusting structure of the speed regulating oil needle in the hydraulic buffer mechanism is positioned below the hydraulic buffer mechanism, the speed of the hydraulic buffer mechanism must be adjusted before the hinge is installed, the speed of the hydraulic buffer mechanism cannot be adjusted after the shell of the hinge is embedded into the door leaf or the door frame, if the closing speed of the hydraulic buffer mechanism is not ideal, the hinge is detached from the door and then the speed regulating oil needle is adjusted when the closing speed of the hydraulic buffer mechanism needs to be adjusted, and therefore, the repeated operation, the debugging and the installation processes are very inconvenient.

Therefore, the hinge capable of being adjusted without disassembly appears in the market, for example, chinese patent utility model with the bulletin number of CN219691329U discloses a hydraulic functional shaft, which comprises an outer shell, a shaft core, a piston, an upper sealing cover and a lower sealing cover which are respectively arranged at two ends of the outer shell, one end of the shaft core is movably inserted into the piston, a space for the shaft core to move axially is arranged in the piston, the outer shell is sleeved on the shaft core, a pushing spring for pushing the piston is arranged between the outer shell and the shaft core, a piston cover is arranged in the piston, a one-way valve and a speed regulating valve hole are arranged on the piston cover, the speed regulating valve hole is communicated with an inner cavity of the piston, the hydraulic functional shaft also comprises a speed regulating oil needle, a needle rod and a driving part, wherein the needle rod and the driving part are respectively arranged at two ends of the connecting part, the connecting part is in threaded connection with the lower sealing cover, the needle rod is in a variable-diameter shape, the driving part is movably connected with the speed regulating valve hole, the driving part stretches out of the lower sealing cover, and the driving part is provided with a driving structure along the circumferential direction of the shaft core.
