Invisible handle

Abstract

The invention discloses an invisible handle which comprises a panel, a frame, a pressing plate, a connecting assembly, a lock catch, a spring fixing piece and a shell. The panel is assembled in the frame in a limited manner, a fixing column is welded to the upper end of the inner surface of the panel, the pressing plate is welded to the lower end of the inner surface of the panel, and the spring fixing piece is lifted to the lower side of the fixing column through a sleeve piece. The cross section of the sleeve piece is of the annular design, the sleeve piece can be arranged on the surface ofthe fixing column in a sleeving manner, a connecting spring is welded to the lower surface of the spring fixing piece, a spring moving piece is welded to the lower surface of the connecting spring, and the spring moving piece and the connecting assembly are of the integrated design; and a lock catch moving groove is formed between the connecting assembly and the spring moving piece, and the lock catch is assembled in the moving groove. By means of the invisible handle, the plane of the handle is flush with a profile, so that the handle is more attractive; and during operation, a lock device can be opened through only one action to finish door opening work, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an invisible handle. Background technique [0002] Door and window handles generally have the function of locking doors and windows, and the existing auxiliary locking methods are either pressed up and down or rotated. [0003] Pins are used to connect the handle with the transmission block, and then the handle is limited by shrapnel. After the torque is converted into thrust, the lock is transmitted through the fork to unlock the door and window. The above scheme, because the torsion force forms a large shear force at the pin, there is a hidden danger of fatigue fracture after a certain number of uses, and the painting process can only be done after using the pin, which affects the efficiency; It is relatively blunt and not smooth, which affects the user experience. [0004] Pressing up and down to open the lock device requires two operations, and it is not easy to d...

Problems solved by technology

The above scheme, because the torsion force forms a large shear force at the pin, there is a hidden danger of fatigue fracture after a certain number of uses, and the painting process can only be done after using the pin, which affects the efficiency; Relatively blunt, not smooth, affecting the user experience

[0004] Pressing up and down to open the lock device requires two operations, and it is not easy to distinguish whether the current state is the lock is opened or the lock is closed. It needs to be pushed and pulled to try to be clear. The operation is cumbersome and has certain problems with the handle hardware. destructive
