Problems solved by technology

The problem with the existing three-position operating mechanism is that the motor must be cut off when the disc cam rotates to the corresponding positions of opening, closing and grounding. If the motor is not cut off, the disc cam continues Rotation will have serious consequences on the ring network cabinet

Embodiment Construction

[0026] An example of a three-position operating mechanism Figure 1~10 Shown: including a frame, the frame is provided with a motor 1, a manual operating lever 23, a transmission shaft 6 and an output shaft parallel to the transmission shaft, and the motor shaft 25 of the motor is connected to the transmission shaft 6 through a gear transmission mechanism 5 , the output end of the manual operating lever 23 is provided with a transmission sleeve 24 which is used to prevent rotation and is set on the motor shaft, and an unlocking plate 26 and an unlocking travel switch 2 are arranged beside the manual operating lever, and the unlocking plate 26 is hinged on the frame. The hinge axis of the unlocking plate is perpendicular to the axial direction of the motor shaft. The outer peripheral surface of the drive sleeve has a conical thrust section. The inner plate surface of the travel switch 2 pushes and fits. When the motor is in the working mode, the transmission sleeve 24 on the ma...

Abstract

The invention relates to a three-position operating mechanism and a transmission shaft thereof. The three-position operating mechanism comprises a motor and a transmission shaft in transmission connection with the motor, wherein the transmission shaft comprises a shaft body with an axis extending along a front-rear direction, a cutoff cam is fixedly arranged on the shaft body, the cutoff cam is provided with a grounding position bulge, an opening position bulge and a closing position bulge which are arranged at intervals around the circumferential direction, and the opening position bulge is arranged in a manner of being staggered relative to the grounding position bulge and the closing position bulge in the front-rear direction. The three-position operating mechanism further comprises a grounding travel switch, an opening travel switch and a closing travel switch which are respectively used for being in push fit with the grounding position bulge, the opening position bulge and the closing position bulge to respectively cut off the motor when the transmission shaft rotates to a grounding position, an opening position and a closing position. The invention provides the three-position operating mechanism which can cut off the motor when the transmission shaft rotates in place and the transmission shaft used in the three-position operating mechanism.

Description

technical field [0001] The invention relates to a three-station operating mechanism and its transmission shaft. Background technique [0002] At present, with the emergence of more and more ring network cabinets in the domestic and foreign markets, the three-station operating mechanism is an important part of the ring network cabinet, and its performance directly determines the quality of the ring network cabinet. Existing three-position operating mechanism, such as the "three-position self-locking cam operating mechanism and its operating method" disclosed in Chinese patent CN102751129A, discloses such a three-position operating mechanism in this patent document, including a motor , the manual operating lever and the first transmission shaft connected to the output end of the motor and the manual operating lever, and also includes a second transmission shaft parallel to the first transmission shaft, and a disc cam is fixed on the first transmission shaft , the disc cam is ...
