Door lock back locking safety knob mechanism
The invention relates to a door lock back locking safety knob mechanism which comprises a knob, a limiting gasket, a lock panel and a tubular fixing piece, a through hole is formed in the lock panel, and the fixing piece is arranged at one end of the lock panel and connected with the lock panel; the knob is arranged at the other end of the lock panel, and a rotating shaft part of the knob penetrates through the through hole and the fixing piece and is connected with the fixing piece; the base body of the knob extends into the through hole and is tightly attached to the fixing piece. A limiting groove is formed in the end face, close to the fixing piece, of the base body of the knob and surrounds the rotating shaft part of the knob. The limiting gasket sleeves the rotating shaft part of the knob and is positioned in the limiting groove; a positioning hole is formed in the limiting gasket; blind holes are formed in the inner walls of the fixing pieces, springs and steel balls are arranged in the blind holes, and the steel balls are arranged at the ends, close to the through hole, of the springs. The spring pushes the steel ball to be tightly attached to the limiting gasket, and one end of the steel ball sinks into the positioning hole. Compared with the prior art, the accurate positioning of knob rotation is achieved, and hand feeling feedback is achieved; vacancy is reduced, and shaking is not prone to being generated.
本发明涉及一种门锁反锁保险旋扭机构，包括旋钮、限位垫片、锁面板和管状的固定件，锁面板上设置有穿孔，固定件置于锁面板的一端，固定件与锁面板连接；旋钮置于锁面板的另一端，旋钮的转轴部穿过穿孔和固定件，并与固定件连接；旋钮的基体伸入穿孔内，并紧贴固定件；旋钮的基体靠近固定件的端面上设置有限位槽，限位槽环绕旋钮的转轴部；限位垫片套在旋钮的转轴部上，并处于限位槽内；限位垫片上设置有定位孔；固定件的内壁上设置有盲孔，盲孔内设置有弹簧和钢珠，钢珠置于弹簧靠近穿孔的一端；弹簧推动钢珠紧贴限位垫片，且钢珠的一端部陷入定位孔内。相对现有技术，本发明实现旋钮旋转精准定位，具有手感反馈；减小虚位，不易产生晃动。
