Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Examples
As shown in fig. 1-5, the utility model provides a C-shaped arm straight arm rotating crankshaft locking device, which comprises a straight arm rotating shaft 1, wherein the straight arm rotating shaft 1 is sleeved with a straight arm 7; the straight arm rotating shaft 1 is fixed on a straight arm 7, and the straight arm rotating lock right part 2 is fixed on a straight arm rotating lock right part fixing device 8; the left part 3 of the straight arm rotary lock is jointed with the right part 2 of the straight arm rotary lock; the upper parts of the surfaces of the left part 3 and the right part 2 of the straight arm rotary lock are provided with gear rings which are meshed with each other, wherein the gear rings are meshed with each other and are seized after being contacted; the straight arm rotary lock left part 3 is separated from the straight arm rotary lock right part 2.
Further, the direction range paddle 6 limits the rotation range of the straight arm 7.
Specifically, the eccentric shaft 4 of the straight arm rotary lock pushes the left part 3 of the straight arm rotary lock to extrude the spring 9, and the spring 9 approaches the right part 2 of the straight arm rotary lock; the straight arm rotating shaft 1 is fixed on a straight arm 7, the straight arm rotating lock right part 2 is fixed on a straight arm rotating lock right part fixing device 8, a direction range shifting piece 6 exists, the rotating range of the straight arm 7 is limited, after the rotating straight arm 7 reaches a required position, a handle is rotated, the straight arm rotating lock eccentric shaft 4 is driven to rotate, the straight arm rotating lock eccentric shaft 4 pushes the straight arm rotating lock left part 3 to extrude a spring 9 and approach the straight arm rotating lock right part 2, after the maximum rotating range allowed by the rotating angle range fixing shifting piece 5 is reached, the straight arm rotating lock left part 3 is attached to the straight arm rotating lock right part 2, gear rings meshed with each other are arranged on the surfaces of the straight arm rotating lock left part 3 and the straight arm rotating lock right part 2, and the gear rings meshed with each other after the contact are meshed with each other, so that the locking purpose is achieved. When the handle is rotated reversely, the left part 3 of the straight arm rotary lock is separated from the right part 2 of the straight arm rotary lock under the action of the spring 9, the locking is released, and the straight arm 7 can rotate again within the allowable range of the direction range shifting piece 6. The above processes are repeated to achieve the purpose of free locking and unlocking.
