Conductive ring-free limiting protection device

Abstract

A conductive ring-free limiting protection device is disclosed, including a base, a support plate is fixedly connected with the upper end face of the base in front-rear symmetry, the support plate isprovided with a rotating space in which a front-rear end wall end penetrates the front and rear end faces of the support plate, A limit space communicating with that rotate space on the left side of the lower end wall is arranged in the upper end wall of the rotating space, A low end wall communicating with a pushing space of that limit space is arranged in the upper end wall of the limiting space, an uplifting space is arrange in the upper end wall of the pushing space, a lifting mechanism is arranged in the uplifting space, and a right end wall communicating with the lifting space of the pushing space is arranged in the left end wall of the limiting space. The device has simple structure and convenient operation. In the work of the invention, the number of position limiting devices is used to limit the number of rotation turns of the conductor, and the rotation of the conductor can be controlled, so as to limit the safety of the protection conductor and improve the safety coefficientof the conductor.

Description

technical field [0001] The invention relates to the field of safe electricity utilization, in particular to a limit protection device without a conductive ring. Background technique [0002] At present, with the development of science and technology and the progress of society, it has become the choice of most manufacturers to replace human labor with machinery. However, machinery is inseparable from the connection of wires, etc., and it is inevitable that wires will be entangled during mechanical work, causing safety problems. Hidden danger, when there is no conductive ring, most of the machines at this stage avoid winding by bundling the wires, which greatly increases the safety hazard, and cannot effectively solve the problem of wire winding damage due to rotation. Contents of the invention [0003] The object of the present invention is to provide a limit protection device without a conductive ring, so as to solve the problems raised in the above-mentioned background t...
