Detailed Description

The utility model is further described below with reference to the accompanying drawings.

The rotary stopping mechanism shown in fig. 1-8 comprises a fixed support 1, a stopping rod 2 is arranged in front of the fixed support 1, the outer end of the stopping rod 2 is movably connected with the fixed support 1 through a short rotating shaft 6, the short rotating shaft 6 is fixedly connected with the fixed support 1 through a nut, the stopping rod 2 rotates by taking the short rotating shaft 6 as the center of a circle, a winch 3 is arranged in front of the stopping rod 2, the winch 3 is movably connected with the fixed support 1 through a long rotating shaft 8, the long rotating shaft 8 is fixedly connected with the fixed support 1 through a bolt, the winch 3 rotates by taking the long rotating shaft 8 as the center of a circle, a torsion spring 5 is arranged between the winch 3 and the fixed support 1, two ends of the torsion spring 5 are fixedly connected with the winch 3 and the fixed support 1, the torsion spring 5 provides a restoring force opposite to the working rotation direction for the winch 3, a guide rail 4 is arranged on the winch 3, the guide rail 4 is arranged on the back of the winch 3, the whole shape of the guide rail 4 is in a bent arrow shape, a limit post 7 is arranged at the inner end of the stopping rod 2, the limit post 7 is clamped into the guide rail 4, one end of the stopping rod 2 slides in the guide rail 4 in the process of stopping the process, and the stop of the winch 3 reaches the preset position to achieve the stopping aim.

The front-rear, inner-outer, and other directions are only described with reference to the drawings, and the specific positional relationship between the components is not limited.

When the winch 3 is driven to rotate by external force during use, the stopping rod 2 can follow swing when the winch 3 rotates to the opening limit position shown in fig. 4, the winch 3 can rotate in the forward direction due to the fact that the force for rotating the winch 3 is removed due to the hard limit effect, the guide rail 4 on the winch 3 can guide the limiting column 7 on the stopping rod 2 to the stopping position shown in fig. 5 due to the fact that the two ends of the stopping rod 2 are fixed, rotation of the winch 3 is limited, and stopping is achieved. When the winch 3 needs to be reset, the winch 3 is rotated again to the reset limit position shown in fig. 6, the winch 3 cannot rotate continuously again due to the hard limit effect, the force for rotating the winch 3 is removed, the winch 3 can rotate back due to the torsion spring 5, and the guide rail 4 on the winch 3 can guide the limit post 7 on the stop rod 2 to the initial position shown in fig. 3.

The emergency unlocking door lock, engine hood lock, trunk lock and other parts on the automobile need to use a switch with a stopping mechanism to achieve the aim of stopping after opening, but the existing switch with the stopping mechanism has sporadic clamping stagnation, the size of the stopping mechanism is large, the part space is limited, the size chain of the stopping mechanism is long, the fault tolerance rate is low, and a part of the stopping mechanism needs to be electrified and operated.
