technical field

The invention relates to an operating unit, in particular to an operating unit of a switching device and a switching device group including the operating unit.

Background technique

In the switching device (such as isolating switch, etc.), by operating the drive shaft to switch between the open position and the closed position, the drive shaft is driven to make the movable contact contact and separate from the fixed contact, thereby controlling the switching device to close or disconnect, so as to realize On-off control of power supply lines.

For a switching device or a switching device group composed of several switching devices, it is often necessary to apply an external force through a handle or the like to change the state of the switching device (group). Restricted by the location of the switching device in the cabinet or other occasions, the user sometimes needs to perform the operation from different directions, such as from the front or side, but the current switching device only has a frontal operation mode.

Detailed ways

In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, in which the same reference numerals represent the same parts.

Chinese patent application CN102468077A discloses a switch control device, which has a compact structure, is stable and reliable, and occupies little space. Based on the switch manipulation device, the present invention provides an operation unit that is easy to manipulate the switch device (such as the switch in CN102468077A) from the side to switch the switch device in different states.

As shown in Figures 1 and 2, the operating unit has a housing 16, the housing 16 has a through hole 17, the operating shaft 11 can be placed in the through hole 17, and a part of the operating shaft 11 extends into the housing 16 There is also a part protruding from the outside of the housing 16 as an operating part, so that it is convenient for the user to perform a corresponding rotation operation on the outside of the housing through a handle or the like.

One end of the operating shaft 11 extending into the housing 16 has an operating head 18, the operating shaft 11 can rotate in the through hole 17, thereby driving the operating head 18 to rotate, specifically, the operating head 18 can be connected with the switch control device 20 The operation hole 22 cooperates, that is to say, when the operation head 18 is embedded in the operation hole 22, since the operation head 18 has a shape adapted to the operation hole 22, the rotation of the operation head 18 can drive the movement of the operation hole 22, thereby The state switching of the switch operating device 20 is driven.

Since in the switch control device 20, there is a certain gap in the switching process from the OFF state to the ON state, if there is no additional design, the same gap will appear in the operating head 18, in order to avoid the gap affecting the operator's feel , while avoiding the shaking of the operating shaft 11 during this process, in conjunction with Fig. 3, the side of the operating shaft 11 close to the operating head 18 also has a cam 15, so that the operating shaft 11 will also drive the cam 15 to rotate when it rotates. Simultaneously, there is also a pair of elastic mechanisms 123 oppositely arranged on both sides of the operating shaft 18. The elastic mechanisms 123 can include a slider 12 and a spring 13 nested in the slider 12. One end of the elastic mechanism 123 is pushed against by the slider 12. Leaning against the cam 15, of course, the elastic mechanism 123 can also have other forms, such as a plug with a spring sheathed outside. The pair of elastic mechanisms are symmetrically arranged along the axis of the operating shaft 11, so that they can better bear against the cam 15, so that the movement of the cam is always carried out smoothly under the abutment of the elastic mechanism, so that the user feels better when operating , will not cause shaking due to idle travel and other reasons.

In addition, the housing 16 also has limit mechanisms 14 and 19 that limit the movement range of the cam 15 . As shown in FIG. 3 , the limiting mechanism 14 and the limiting mechanism 19 are arranged symmetrically along the axis of the operating shaft 11 and perpendicular to the elastic mechanism 123 , that is, the limiting mechanism and the elastic mechanism form an angle of 90 degrees. In this way, the operating shaft can be switched between the ON position and the OFF position within a 90-degree rotation range. When the switching device reaches the OFF position or the ON position, the existence of the limit mechanism makes it possible to continue to rotate the operating shaft in the original direction. Impossible, but can only change state according to turning in the opposite direction, like this, will more conveniently indicate the current accurate state of switching device to the operator.

A state switching process is described in conjunction with FIG. 3 to FIG. 6 .

In FIG. 3 , the switching device is in the OFF state, and the cam 15 is abutted against by a pair of sliders 12 of the elastic mechanism in the middle, and by the limit surface 141 on the limit mechanism 14 and the limit surface 192 on the limit mechanism 19 Clockwise motion tendency is limited.

If it is necessary to manually switch the state of the switching device to the ON state, you can operate the operating part of the operating shaft 11 to make the operating shaft rotate counterclockwise, and the cam 15 will compress the slider 12 and then compress the elastic mechanism 123, so that the spring compression reaches the maximum At this time, as shown in Figure 4, the elastic mechanism is at the dead point position, and correspondingly, in the switch operating device 20, the spring is also at the dead point position at this time, that is to say, there are two operating units and the switch operating device. Charge at a dead point.

In Fig. 5, the operating shaft 11 continues to rotate counterclockwise, and the slider 12 of the elastic mechanism continues to abut against the cam 15, so that even if there is a lost motion in the switch operating device 20, the operator will not feel obvious existence , and, relying on the stored force at the dead point, the operating shaft 11 can easily continue to rotate until the ON state shown in Figure 6, at this time, the slider 12 is still against the cam 15, and the cam 15 is also limited The blocking of the limiting surface 142 of the mechanism 14 and the limiting surface 191 of the limiting mechanism 19 prevents further counterclockwise rotation.

The present invention also provides a switching device group, as shown in Figure 7, the switching device group includes a plurality of switching devices, three switching devices 31, 32 and 33 are shown in Figure 7, in addition, a switch Operating mechanism 20 and an operating unit 10, switch operating mechanism 20 is connected with operating unit 10, like this, just there are two manipulation directions of front and side, in Fig. To switch the states of the switching devices 31, 32 and 33, the states of the switching devices 31, 32 and 33 are switched on one side by the operating shaft 11 of the operating unit 10, while the two shafts 11 and 21 are in a vertical state. In this way, by adding a single operation unit 10, the user can be provided with the possibility to switch the state at the side, providing an additional usage scenario for the switching device group.

Specifically, the operation unit 10 can be used as a separately sold product, and the side wall of the operation unit 10 can be disassembled, and then it can be fixed with the switch operating mechanism 20 by fasteners such as bolts.
