Description

Full-sealed brake with handle Technical Field The utility model relates to the technical field, in particular to a full-sealing brake with a handle. Background The electromagnetic brake is generally arranged on the motor, a friction plate in the electromagnetic brake is matched with a rotating shaft of the motor, an armature is arranged on one side of the friction plate, and the armature is pushed to be pressed against the friction plate under the action of the elasticity of a built-in spring, so that the rotating freedom degree of the rotating shaft is limited through the braking effect of the friction plate. When the braking is required to be released, an electromagnetic coil in the electromagnetic brake starter attracts an armature to be far away from a friction plate, and the braking effect is released. In some cases, the solenoid may fail, resulting in a braking condition that cannot be relieved, such as when the coil is damaged, the power source is a mobile power source, and the power is exhausted. For this reason, a graspable member such as a handle for manually releasing the brake is separately provided for the user to manually release the locked state. However, the electromagnetic brake also needs to meet the sealing requirement, if not, water seepage and shortened service life can be caused, and the handle can damage the external integral structure of the electromagnetic brake, so that the sealing structure of the electromagnetic brake is damaged, and a series of negative effects such as reduced service life and the like are generated. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide a full-sealed brake with a handle, which can maintain a good sealing structure after the handle is additionally arranged. The aim of the utility model is realized by the following technical scheme: The full-sealed brake with the handle comprises a cover plate and a shell, wherein the cover plate is used for being fixed to a motor, the shell is provided with an opening at one side, the cover plate is matched to the opening side of the shell and is used for limiting a containing cavity, at least an armature, a friction plate and an electromagnetic coil are arranged in the containing cavity. The utility model has the beneficial effects that when the first bolt is screwed down, the matching section is strongly pressed to the corresponding surface of the shell in the axis direction of the bolt, so that the contact surface between the matching section and the shell is tightly attached. The compression effect generates local high pressure at the through position of the first bolt, and effectively closes the micro gap, so that a reliable sealing interface is formed at the connecting point, the integral sealing structure of the brake is maintained, the reduction of the sealing performance caused by the arrangement of the handle is avoided, and the long-term use of the brake in a wet or dusty environment is ensured. Further, the nut of the first bolt is located in the accommodating cavity, the screw rod section of the first bolt is sleeved with the nut, and one side of the nut is pressed against one side of the matching section away from the shell.
