Description

Technical Field

[0001] The utility model relates to the technical field of door lock handles, in particular to a three-in-one split door lock handle round cover structure. Background Art

[0002] Traditional door handle (handle round cover adopts two-piece design). The handle round cover has a smaller middle hole because it covers a circle of screw heads on the handle base. This two-piece design of the handle round cover cannot make the middle hole of the handle round cover larger due to the standard lock core (hole distance 38mm) on the market. This will result in the handle round cover being unable to pass through the right angles of various shapes of handles (resulting in limited innovation in handle shapes).

[0003] At the same time, the traditional door handle (the handle cover adopts a two-piece design). This two-piece design of the handle cover will cause the handle cover to be inserted into the handle foot before the handle is installed (the reason: it cannot pass through the right angle of the handle, and needs to be inserted into the handle foot from the root of the handle in advance). Because the handle cover stays at the handle foot, it will be inconvenient to use a screwdriver to tighten the screw (in serious cases, the screwdriver may not be inserted). Utility Model Content

The locking method of the retracted screws in the three-piece design of the door handle is optimized (the two screw heads are in opposite directions). In this way, the installer does not need to distinguish the installation position of the handle base plate, which facilitates installation and prevents errors.

[0015] Preferably, any of the above schemes is that a spiral spring is installed between the handle disc and the handle bottom plate, and the spring is sleeved on the square steel.

[0016] The above technical solution is adopted: the spiral spring is used to provide the torque when the handle is rotated, and the handle is reset when the handle is released.

[0017] Preferably, any of the above solutions has a circular hole in the middle of the handle round cover.

[0018] The above technical solution is adopted: the handle cover adopts a three-piece design, so the long rod screw is installed first to realize the connection of the handle base plate, and then the right-angle handle and the handle round plate are installed, and finally the handle round cover is installed. Since the handle round cover can pass through the foot of the right-angle handle, the handle round cover can be installed last without affecting or interfering with the tightening operation of the long rod screw.
