Fig. 2 is the partial view of the contact position schematically shown between stationary contacts and movable contact;
Fig. 3 is the schematic diagram of the operation illustrated according to adjusting device of the present invention; And
Figure 4 and 5 are schematic diagrames of two different adjustment positions of the position that operating axis is shown.
Embodiment
In FIG, can see that rocking bar 1 supports the movable contact 2 belonged to according to middle pressure electric protective equipment of the present invention.The mechanism that this rocking bar 1 is included control lever 4 by means of operating axis 3 drives rotation.This control lever 4 is designed to the drive rod 5 being in the operating axis 3 of drive rocker 1 between the primary importance of the primary importance being called aligned position and the second place at rocking bar, at described aligned position, its movable contact 2 contacts with the stationary contacts of equipment, and in the second place, this movable contact 2 and stationary contacts 6 separated from one another.
According to the present invention, the driving of control lever 4 pairs of drive rods 5 is carried out by means of adjusting device.This adjusting device comprises the first bar 7, this first bar 7 is connected on drive rod 5 via one end thereof (being called first end) 7a in hinged way, and comprise pin 8 in the other end being called the second end 7b, the hole 9 that the end being called first end 10a that this pin 8 is arranged in the second bar 10 is arranged, the second end 10b of this second bar 10 is connected in hinged way and belongs on the control lever 4 of this mechanism, and this second bar is rotatably installed by the operating axis 3 around rocking bar 1 between these two ends 10a, 10b.The motion of pin 8 in hole 9 is designed to the rotary motion causing the first bar 7, and therefore by means of to be arranged on the one hand on drive rod 5 and the tooth 11 be arranged on operating axis 3 causes the rotary motion of the drive rod 5 of operating axis 3 on the other hand, this causes the change of the position of rotation of rocking bar 1.
This drive rod 5 comprises two two bars in the face of part 5a, 5b, and these two connect in the face of the folding of partly in its end, and these two parts lay respectively on every side of the first bar 7 and the second bar 10, and operating axis 3 is through them.This adjusting device also comprises such device, and this device is designed to be pressed on the second bar 10 by the first bar 7 in the position of hinged 7b by two part 10c, 10d of the control lever 10 that moves up in mutual side.This extrusion system comprises the screw 12 be threaded in the pin 8 forming nut.Screw 12 is threaded in pin 8 bar 10c, 10d and 7 to be pressed onto and goes up each other, until obtain clamping fully, keeps the relative position between the first bar 7 and the second bar 10, prevents the change of this relative position thus.
With reference to Figure 4 and 5, the operation according to the electric protective equipment of particular implementation of the present invention is described below.First, through comprising the opened/closed mechanism of control lever 4, rocking bar 1 moves to the position being called aligned position, in this position, and movable contact 2 and stationary contacts 6 electrical contact.Then, when two contacts 2,6 are closed, the adjustment more accurately of the relative position of two contacts is carried out as follows, that is: by the direction translation pin 8 along the one end in hole or the other end in hole 9, therefore, depend on whether the drive rod 5 of operating axis 3 moves respectively in the clockwise direction or in the counterclockwise direction, in the counterclockwise direction or clockwise direction drive the first bar 7.
In the diagram, the pin 8 be associated with the first bar 7 is positioned at one of them end in hole 9, angle between drive rod 5 and the second bar 10 is minimum, and this corresponds to the minimum movement value driving dry 5, and therefore corresponds to operating axis 3 minimum movement value in the counterclockwise direction.
In Figure 5, pin 8 moves towards the other end in hole 9, and this corresponds to the maximum between drive rod 5 and the second bar 10, and therefore corresponds to operating axis 3 maximum rotary motion in the clockwise direction.
After this regulates, by being clamped in by screw 12, pin 8 is interior obtains the clamping of the first bar 7 on the second bar 10 and the clamping in the position of pin 8 in hole 9 thus to move towards each other two parts of bar 10, performs rocking bar 1 fix in position.Thus by means of the present invention, the power needed when performing adjustment operation, that is: the moment of torsion applied in the position of rocking bar 1, is substantially perpendicular to adjustment hole 9 and applies, and the position that this power is keeping regulating is transmitted.Therefore in hole, there is very little slip stress.Thus, after system is fixing, can not becomes by sliding in hole 9 and float and regulate.
Therefore, the present invention proposes a kind of adjusting device of rocking bar 1 of simplicity of design, it can reduce the skew of the blade of rocking bar or bar at closed aligned position when multipole device.
The present invention is never confined to describe and illustrated execution mode naturally, and these execution modes only provide with the object of citing.On the contrary, the present invention extends to all technical equivalents and combination thereof that contain described device, as long as the latter carries out according to marrow of the present invention.
