Description

Technical Field

[0001] The invention relates to the technical field of door handles, and in particular to a push-down and lift-back door handle which is convenient for replacing the handle. Background Art

[0002] Door handles are indispensable door accessories that cannot be ignored. They are both decorative and functional. Door handles are classified into ceramic, solid wood, metal, glass, crystal, plastic, alloy and other materials. Door handles are classified into single-hole spherical, single-hole bar or Japanese, Chinese modern, European and other styles according to their shapes. People can choose the material according to their needs. In order to facilitate the opening and closing of the door lock on the indoor door body, two door handles are often installed symmetrically at the door lock on the door body.

[0003] Then, the current door handles mainly adopt an integrated structure, which means that when the door handle needs to be replaced after being used for a period of time, the entire door lock must be removed, and then the handle on the door handle can be replaced. The entire operation process is relatively cumbersome, which greatly reduces the replacement efficiency of the door handle and is not convenient for efficient inspection and maintenance of the door handle in the later stage. Secondly, the current door handles can only be turned downward when in use, which makes the door handle opening method not flexible enough and the usage method is relatively single, which greatly reduces the flexibility of the door handle. Summary of the invention

[0007] Furthermore, the eccentric square bar is plugged into the first handle and the second handle, and the first handle and the second handle are both connected to the eccentric square bar at locations that have a square concave structure.

[0008] By adopting the above technical solution, it is possible to ensure reliable installation of the eccentric square bar, the first handle and the second handle.

[0009] Furthermore, the eccentric hole is formed on the eccentric square bar, and the eccentric square bar adopts a concave structure at a position facing the limiting column.

[0010] By adopting the above technical solution, after the tightening screw is screwed in, the limiting column can extend into the eccentric square bar to achieve reliable installation and fixation of the handle 1 and the handle 2.

[0011] Furthermore, the screw holes are formed on the first handle and the second handle, and the tightening screws are screwed into the screw holes.

[0012] By adopting the above technical solution, the tightening screw can realize the convenient disassembly and assembly of the handle 1 and the handle 2.

[0013] Furthermore, the first handle and the second handle are both made of die-cast aluminum, and the handle groove is formed on the first handle and the second handle.

[0014] By adopting the above technical solution, the handle groove cooperates with the rotating block boss, so that the rotating block can be easily rotated along with the handle 1 and the handle 2.

[0015] Furthermore, the hexagonal groove and the limiting column are both formed on the tightening screw, and the limiting column is inserted into the eccentric hole.

[0016] By adopting the above technical solution, the hexagonal groove is connected to the external rotating handle, so that the fastening screw can be easily disassembled.

[0025] The specific working principle is: when in use, first pass the eccentric square bar through the inside of the lock core on the door body, then install the outer ring, the base, the rotating block and the bottom plate on the handle 1 and the handle 2 respectively, then pass the eccentric square bar through the outer ring, the base, the rotating block and the bottom plate, and insert the two ends of the eccentric square bar into the handle 1 and the handle 2 respectively, at the same time, use the external turning handle to tighten the locking screw, and use the cross countersunk screw and the cross nut to connect the two bases, so that the door handle can be put into use. During use, through the interaction between the rotating block, the bidirectional torsion spring and the base, the handle 1 and the handle 2 can not only be rotated upward, but also be rotated downward, and the rotation angle is 60°, so that the door lock can be opened conveniently and the flexibility of the handle can be improved. When the door handle needs to be replaced after being used for a period of time, it is only necessary to unscrew the locking screw through the external handle and tighten the locking screw again after replacing the new handle, so as to realize the convenient replacement of the door handle and facilitate the efficient inspection and maintenance of the door handle in the later stage.
