Example Embodiment

[0014] The structure and use of the present invention will now be further described with reference to the drawings. Such as figure 1 As shown, figure 1 It is the state when the mechanism is almost closing in place, and the closing ends when the roller on the eccentric rotates clockwise and contacts the detent surface. One side of the side plate 6 of the operating mechanism is provided with an eccentric wheel 1, a spring 2 and a detent 4. The side plate at the spring is symmetrically provided with limit ribs, and the spring is arranged in the spring groove between the limit ribs; The spring seats are respectively provided with spring rollers, and the spring rollers of the spring seats at both ends are arranged in the sliding holes of the side plate through the spring shaft; the eccentric wheel is connected with one end of the main shaft 5, and the shaft centers of the main shaft and the spring roller are on the same straight line. The outer wheel surface of the eccentric wheel...

Abstract

The invention relates to an operating mechanism for a three-position closing band holding device, aiming at the technical problem that a holding device in a current like product is not good enough in the design of safety. The operating mechanism comprises an eccentric gear, a spring and a grabbing element, wherein the eccentric gear is connected with a main shaft; a roller is arranged at the outside gear surface; and the circumferential surface of the eccentric gear abuts against a spring roller at one end of the spring. The operating mechanism is characterized in that the eccentric gear is an irregular cam; the circumferential surface at one side of the axle center of the eccentric gear is provided with a spacing groove; the circumferential surface at two sides of the spacing groove and one symmetrical side of the spacing groove are arc bulges, that is, one side of the roller of the spacing groove in the eccentric gear enlarges in a spiral shape towards the other symmetrical side; and the roller is arranged at the middle part between a spiral enlargement starting point of the eccentric gear and the symmetrical side of the spacing groove; the L-shaped grabbing element bends downward, and the outside of the bending end is provided with a spacing end groove, and the other end is fixed at a side plate through a pin roll; the eccentric gear keeps abutting against the roller at one end of the spring; and when the eccentric gear arrives at one position, the energy of the spring is released gradually.

Description

technical field [0001] The invention relates to a three-station mechanism of a high-voltage switch, which is an operating mechanism of a three-station closing belt holding device. Background technique [0002] The three-position mechanism of the high-voltage switch has been developed to this day, and there have been some unsatisfactory designs. For example, the traditional three-position mechanism with a fuse. The energy source of the mechanism opening has always been a shortcoming of the mechanism design. The energy of the three-station mechanism basically has the characteristics of instant storage and use, and there is no concept of energy storage for use. Therefore, the power supply department needs a mechanism that can have the function of breaking the circuit when it needs to be broken, instead of going to manual or mechanical energy storage and then opening the switch when it wants to break the circuit, which is dangerous and not allowed in time. Among them, the cams ...
