Detailed ways

Referring to Figures 1 to 6, as shown, a concealed door handle includes: a panel 1 having a recess 2; a handle body 3 disposed within the recess 2, the handle body 3 The outer surface is substantially flush with the outer surface of the panel 1, and the handle body 3 is pivotally connected to the panel 1 and is rotatable relative to the panel 1 within the recess 2.

The invention provides a recess 2 on the panel 1. The handle body 3 is pivotally connected in the recess 2, and the outer surface thereof is substantially flush with the outer surface of the panel 1. By hiding the handle body 3 in the recess 2, the design is not only reasonable. The utility model has the advantages of beautiful appearance, strong consistency, and avoiding the hidden trouble caused by the exposed body 3 of the handle body, and has high practicability. As shown in FIG. 7 , when the handle body 3 is rotated relative to the panel 1 in the recess 2 , the handle body 3 is The bolt 17 in the lock body 16 can be moved between an extended position and a retracted position, where the bolt 17 includes a tongue and a main bolt. The structure of each component will be described in detail below.

The handle body 3 is provided with a handle square shaft 4, which can be rotated relative to the panel 1 with the handle square shaft 4 as a pivot axis, and the panel 1 includes a cover 5 and a bottom plate 6, both of which can be screwed, The first cover 7 and the second opening 8 for the handle square shaft 4 are respectively disposed on the cover 5 and the bottom plate 6, and the handle square shaft 4 passes through the first opening 7, After the second opening 8 is connected with the handle shaft mounted on the door lock body 16, the rotating handle body 3 can drive the handle shaft to rotate, thereby driving the bolt 17 in the lock body 16 in the extended position and the retracted position. Move between. In the present embodiment, the recess 2 is provided on the face cover 5, and after the handle body 3 is placed in the recess 2, the surface thereof is substantially flush with the surface of the face cover 5.

Specifically, the torsion spring 9, the first connecting member 10 and the retaining spring 11 are included. The first connecting member 10 is, for example, a rotating piece. After the square shaft 4 of the handle passes through the first opening 7, the torsion spring 9 and the rotating piece are rotated. The sleeve square shaft 4 is sequentially sleeved, wherein an inner concave portion and a convex portion are disposed between the handle square shaft 4 and the rotating piece, and the convex portion is caught in the inner concave portion, and the rotating piece will rotate together with the handle square shaft 4 The handle square shaft 4 is further provided with a groove for the card spring 11 to be engaged, and the card spring 11 is snapped into the groove to prevent the torsion spring 9 and the rotating piece from being detached from the handle square shaft 4, and the rotating piece is provided with a first protrusion 12 abutting the end of the torsion spring 9, the panel 1 is respectively provided with a second connecting member capable of abutting the end of the torsion spring 9, and the second connecting member may be disposed on the cover 5 or a second protrusion 13 on the bottom plate 6. When the handle body 3 is rotated by an external force, the torsion spring 9 is compressed, and can be reversely rotated back to the initial position by the returning force of the torsion spring 9.
