The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of hand door lock comprises panel 1, handle 2, driving shaft 3, spring 4 and cover plate 5, and driving shaft 3 is rotatably assorted with the axis hole of panel 1, and handle 2 is fixedly connected with driving shaft 3;
The square plate that described panel 1 is made by a metal plate, the axis hole 11 on panel 1 distribute from the rear surface to the front surface successively has draw-in groove 121 on the base plate of the first counterbore 12 and the second counterbore 13, the first counterbores 12; During use, the face on the rear surface of panel 1 and doorframe limit is fitted, for face connects.
Described cover plate 5 is rounded and have centre bore, be positioned at two block tongues 51 of the inherent diameter line of centre bore and be positioned at arcuate guide breach 52 on radial edges; Described spring 4 is a plane scroll spring; Plane scroll spring 4 is arranged in the second counterbore 13, and the radial outside end 41 of plane scroll spring 4 embeds in draw-in groove 121; The surface of institute's cover plate 5 and the rear surface of panel 1 are at grade.
