Embodiment Construction

[0020] Embodiment 1 of a two-position spring operating mechanism for a switchgear, such as Figure 1-7 As shown, there is a housing, the housing has a base plate 1, and a rotating shaft is mounted on the base plate 1. The lower end of the rotating shaft passes through the base plate 1 and is provided with a transmission joint for transmission connection with the switchgear in the switch cabinet. Specifically, The lower end of the rotating shaft is equipped with an output cam 3 for anti-rotation. The camshaft of the output cam 3 is a hollow shaft and has a gap in its circumferential direction. The part where the gap is located forms the transmission joint, and the transmission joint passes through its circumferential direction during use. The gap of the corresponding switch device is fitted; the upper side of the bottom plate 1 on the rotating shaft is anti-rotating and equipped with a spring support, and the spring supporting includes the first turntable 4 and the second turnta...

Abstract

The invention relates to a two-position spring actuating mechanism for switchgear, which comprises a casing. The casing comprises a bottom plate, a rotating shaft is rotatably assembled on the bottom plate, a spring support is assembled on the rotating shaft in a rotation stop manner, a driving mechanism is arranged between the spring support and the casing and comprises more than two guide arms and driving springs sleeved on the guide arms, vertical shafts are rotatably assembled at two ends of each guide arm respectively, at least one of the two vertical shafts of each guide arm is axially and movably matched with the corresponding guide arm, one of the two vertical shafts of each guide arm is vertically arranged on the spring support while the other of the two vertical shafts of each guide arm is arranged on the casing, a point on the axis of one of the two vertical shafts of each guide arm positioned on the casing and the axis of the rotating shaft determines an interface, the other vertical shaft rotates along with the rotating shaft and is provided with a first station and a second station which are arranged on two sides of the interface respectively, and the vertical shafts positioned on the spring support are the same in the rotation direction around the rotating shaft when moving from the first station to the second station. The two-position spring actuating mechanism for the switchgear solves the problem that an existing spring actuating mechanism for switchgear is large in size.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a double-position spring operating mechanism for a switch cabinet. Background technique [0002] With the development of social economy, in densely populated areas, large industrial and mining enterprises, high-rise buildings, etc., due to factors such as floor area and space constraints, it is necessary to choose compact and small power distribution switchgear, which also poses a challenge to the operating mechanism. In order to meet the requirements of miniaturization, most of the operating mechanisms supporting the switchgear are single spring operating mechanisms. Since the switchgear itself needs to close and break large currents, the requirements for opening and closing speed are high, which requires its supporting operation. The volume of the single spring on the mechanism is also correspondingly increased to meet the requirements of the switchgear for opening and closing sp...
