Title:
LOCKING DEVICE AND MEDICAL MECHANICAL ARM
Document Type and Number:
WIPO Patent Application WO/2023/216428
Kind Code:
A1
Abstract:
A locking device (10), comprises: a first connecting mechanism (1) and a first positioning mechanism (3) connected with the first connecting mechanism (1); and a second connecting mechanism (2) and a second positioning mechanism (4) connected with the second connecting mechanism (2), wherein the second positioning mechanism (4) has at least two positioning positions (41); wherein the second connecting mechanism (2) is rotatably connected to the first connecting mechanism (1), and wherein the second positioning mechanism (4) is able to rotate relative to the first positioning mechanism (3) with its own axis as the rotation axis, and the first positioning mechanism (3) is able to mutually lock with and unlock from any one of the positioning positions (41) of the second positioning mechanism (4). Through the fit of the first positioning mechanism (3) and the corresponding positioning position, the second connecting mechanism (2) and the first connecting mechanism (1) can be locked together after the second connecting mechanism (2) rotates a certain angle relative to the first connecting mechanism (1), and the control of the rotation angle of the first connecting mechanism (1) and the second connecting mechanism (2) can be realized without using a servo electric motor or a stepping electric motor, further reducing the cost of the locking device (10). A medical mechanical arm (100) is also provided.
