The invention relates to a brake, in particular to a manual unlocking device for a brake and a motor. The manual unlocking device solves the technical problem that a traditional brake hardly realizes manual unlocking and is hardly continuously kept in an unlocking state under the non-manual action. The manual unlocking device for the brake comprises an unlocking handle arranged on the brake, and further comprises a protective shell and an operating mechanism. The operating mechanism comprises a release rod, a rotating rod, a limiting rod, a connector and a first nut; one end of the release rod extends into the protective shell, and the other end is located outside the protective shell; the rotating rod is arranged on the portion, outside the protective shell, of the release rod, and the limiting rod is arranged on the portion, extending into the protective shell, of the release rod; one end of the connector is provided with a U-shaped opening, and the other end is connected with the unlocking handle; the first nut is connected to the release rod, and the front end face of the first nut is a spherical surface and located on the rear side of the U-shaped opening of the connector; and a rectangular through hole matched with the limiting rod is formed in an end plate, close to the rotating rod, of the protective shell, and the brake is manually unlocked and continuously kept in the unlocking state.
Description
technical field [0001] The invention relates to a brake, in particular to a manual unlocking device and a motor for the brake. Background technique [0002] Traditional brakes with manual release function such as figure 1 and figure 2 As shown, the unlocking handle 2 and the joystick are arranged on the body of the brake 1; the unlocking handle is U-shaped, and the middle part of the upper end is provided with a joystick installation hole, and the joystick is a cylindrical long rod; When using the manual unlock function, the user needs to move the brake to a certain unlocking angle in the specified direction before the brake can be unlocked. To maintain the unlocked state, manpower is required to keep the joystick in the unlocked position. [0003] However, when the brake with manual unlocking function is used for the motor, it is often necessary to consider the sealing of the motor and process the joystick cover to solve the sealing problem of the manual unlocking brake....
