Embodiment Construction
[0042] like Figure 1-6 As shown, a hydraulic closed door hinge includes a door frame sheet 10, a door leaf sheet 25, an inner pipe 6, and a hydraulic inner pipe 6 assembly arranged in the inner pipe 6. The hydraulic pressure The inner tube 6 assembly includes a cam torque conversion mechanism and a hydraulic damping mechanism. The cam torque conversion mechanism includes a cylindrical groove cam 13, a piston rod 14, a pin shaft 24 and a return spring 5. The cylindrical groove cam 13 and the door frame leaf 10 Fixed connection, in the shape of a hollow tube with a curved groove running through the surface, the piston rod 14 and the return spring 5 are coaxially arranged in the cylindrical groove cam 13 in turn, and the piston rod 14 and the cylindrical groove cam 13 do axial sliding and turnover. Matching, one end of the piston rod 14 is provided with a through hole in the radial direction, and the door leaf 25 corresponding to the through hole is provided with an oblong hole ...

A hydraulic door closing hinge comprises a door frame hinge piece, a door leaf hinge piece, an inner pipe and a hydraulic inner pipe assembly arranged in the inner pipe, the hydraulic inner pipe assembly comprises a cam torque conversion mechanism and a hydraulic damping mechanism, and the cam torque conversion mechanism comprises a cylindrical groove cam, a piston rod, a pin shaft and a reset spring. The cylindrical groove cam is fixedly connected with the door frame hinge and is in a hollow pipe shape, a curved groove is formed in the surface of the cylindrical groove cam in a penetrating mode, the piston rod and the reset spring are sequentially and coaxially arranged in the cylindrical groove cam, the piston rod and the cylindrical groove cam are in axial sliding and turnover fit, a through hole is formed in one end of the piston rod in the radial direction, and the door leaf hinge corresponds to the through hole. A long round hole matched with the pin shaft is formed in the axial direction, the pin shaft penetrates through the piston rod through hole, the cylindrical groove cam curve groove and the long round hole, door opening and door closing of the door leaf hinge drive the pin shaft and the piston rod to rotate forwards and backwards, and the pin shaft ascends and descends in the axial direction of the curve groove to drive the piston rod to compress or release the reset spring.
Description
technical field [0001] The invention relates to a door-controlled hinge in the hardware industry, in particular to an automatic door-closing hinge with a cam structure. Background technique [0002] Among the existing hydraulic door closing buffer hinges, the closing door hinges combined with the return spring hinge and the hydraulic speed regulating hinge are used. figure 1 As shown in the figure, the door leaf drives the hinge to open, which together drives the spring core rod 203 and the cam 205 to rotate, and the curved groove on the cam 205 and the pin shaft 208 are in rolling fit. Since the pin shaft 208 does not move, the cam 205 moves toward the spring 202 side. The movement of the axial rotation upward, the compression spring 202 reserves the vertical spring force. [0003] When the external force for opening the door vanishes, the axial spring force stored by the spring 202 is released, which acts in the opposite direction on the cam 205, and is converted into a t...
