Abstract

The invention relates to the technical field of brakes and discloses a bidirectional spring brake. The bidirectional spring brake comprises a brake cover with an inner accommodating cavity, an input spring pusher dog which is connected with a first input shaft of an external input device, an output spring pusher dog which is connected with a second input shaft of the external input device and springs which can be respectively clamped on the input spring pusher dog and the output spring pusher dog. The input spring pusher dog, the spring and the output spring pusher dog are sequentially arranged in the accommodating cavity. The bidirectional spring brake disclosed by the invention is a mechanism and can be used at an input device end and an output device end. The invention has the advantages of low cost, simple structure, high reliability and flexibility in use. The torsion is large during brake, and a brake function can be accurately realized in time. The torsion strength can be adjusted by the springs according to actual conditions. The invention further provides electric equipment comprising the bidirectional spring brake.

Description

technical field

[0001] The invention relates to the technical field of brakes, in particular to a two-way spring brake and electrical equipment including the two-way spring brake. Background technique

[0002] In the prior art, brakes are generally provided between the input device and the output device in some electrical equipment, and the brake can ensure that the electrical equipment has the functions of self-locking, accurate positioning and high safety factor, such as cranes, roller shutters, etc. and other electrical equipment to prevent accidents caused by sudden power failure or power loss of the input device. If there is no electricity or no power, the roller blind machine will slide down due to its own weight, causing a safety accident, and the roller blind machine cannot be positioned accurately, so the brake has been widely used in the existing electrical equipment, but the brake in the prior art The brake device absorbs the brake components through the electrom...
