Abstract

The invention discloses a mechanical arm locking mechanism of a movable DR. The mechanical arm locking mechanism comprises a supporting piece and a lock base, the supporting piece is arranged on a mechanical arm of the movable DR, the lock base is arranged on a machine frame of the movable DR, wherein the supporting piece comprises a support, a locking shaft and a hanging shaft, the support is connected with the mechanical arm, the locking shaft is movably connected with the support, and the hanging shaft is rotatably connected with the support; the lock base comprises a base, a rotating shaft, a hook, an elastic reset element and a driving element, the base is arranged on the machine frame, the rotating shaft is rotatably connected with the base, the center of the rotating shaft and the center of the hanging shaft are staggered in the vertical direction, the hook is rotatably connected with the rotating shaft, and the hook is movably connected with the hanging shaft after penetrating through the base; and the elastic reset element and the driving element are both arranged on the base and connected with the hook. The mechanical arm locking mechanism of the movable DR has the beneficial effects that unlocking is smooth, locking is stable and reliable, and abnormal unlocking cannot occur in the impact state.

Description

technical field [0001] The invention relates to the field of robots, in particular to a locking mechanism of a mechanical arm for moving a DR. Background technique [0002] Generally, when the mechanical arm of the mobile DR (mobile digital X-ray machine) is not working, it is locked on the frame by a locking mechanism. The traditional locking mechanism adopts a lock and pin structure, wherein the lock is set on the frame, and the pin is set on the mechanical arm; when the mechanical arm returns to its original position, the lock cooperates with the pin, and the mechanical arm remains locked ; When the mechanical arm needs to work, the lock pops open and the mechanical arm is unlocked. However, the locking mechanism of the mechanical arm of the traditional mobile DR has the following problems during use: after the mechanical arm is in the locked state, the rack moves, and the mechanical arm will be unlocked when it is impacted, and abnormal unlocking occurs. In addition, u...
