Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
As shown in Figure 1 to 4, the utility model embodiment discloses a kind of being braked without excitation with release lever structure
Device, including release lever 1, microswitch 2, the stator 3 with magnet coil, flexible member 4, armature 5, guide sleeve 6, band friction plate
Rotor 7, axle sleeve 8, installing plate 9, the stator 3 it is cylindrical on described microswitch 2 is installed, the installing plate 9 is installed
In the rear end cap of motor 10, the axle sleeve 8 is fixed on motor shaft, and the rotor 7 is arranged on the axle sleeve 8, and the rotor 7 is set
Put between the installing plate 9 and the armature 5, the stator 3 is arranged on the other end of the armature 5, the stator 3 and institute
To state and multiple guide sleeves 6 are provided between the rear end cap of motor 10, the stator 3 is provided with groove, and flexible member 4 is provided with the groove,
One end of the flexible member 4 is contacted with the armature 5, and release lever 1 is provided between the armature 5 and the installing plate 9,
The installing plate 9 is provided with several straight pins, and the release lever 1 is provided with several arc-shaped limit grooves, the release hand
Handle 1 carries out certain angle rotation around straight pin, and the release lever 1 is provided with several grooves, one is placed in each groove
