Embodiment
In Fig. 1, can see that rocking bar 1 supports the movable contact 2 that belongs to according to middle pressure electric protective equipment of the present invention.This rocking bar 1 drives rotation by means of the mechanism that operating axis 3 is included control lever 4.This control lever 4 is designed to be at rocking bar the drive rod 5 of the operating axis 3 of drive rocker 1 between the primary importance of the primary importance that is called aligned position and the second place, 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 are separated from one another.
According to the present invention, the driving of 4 pairs of drive rods 5 of control lever is carried out by means of adjusting device.This adjusting device comprises the first bar 7, this first bar 7 is connected on the drive rod 5 in hinged way via one end thereof (being called first end) 7a, and comprise pin 8 in the other end that is called the second end 7b, this pin 8 is arranged in the hole 9 of place, the end setting that is called first end 10a of the second bar 10, the second end 10b of this second bar 10 is connected on the control lever 4 that belongs to this mechanism in hinged way, and this second bar is installed by the operating axis 3 around rocking bar 1 between these two end 10a, 10b with rotating freely.The motion of pin 8 in hole 9 is designed to cause rotatablely moving of the first bar 7, therefore and by means of being arranged on the drive rod 5 on the one hand and being arranged on the other hand the rotatablely moving of drive rod 5 that tooth 11 on the operating axis 3 causes operating axis 3, this causes the change of the position of rotation of rocking bar 1.
This drive rod 5 is to comprise two two bars in the face of part 5a, 5b, these two in the face of part through one in its end fold and connect, these two parts lay respectively on each side of the first bar 7 and the second bar 10, and operating axis 3 passes them.This adjusting device also comprises such device, and this device is designed to the first bar 7 is pressed on the second bar 10 in the position of hinged 7b by two part 10c, 10d of mobile control lever 10 on mutual direction.This extrusion system comprises that screw thread is screwed into the screw 12 in the pin 8 that forms nut.Screw 12 screw threads are screwed in the pin 8 bar 10c, 10d and 7 be pressed onto each other and go up, until obtain to clamp fully, keep the relative position between the first bar 7 and the second bar 10, prevent thus the variation of this relative position.
The operation of the electric protective equipment of particular implementation according to the present invention is described with reference to Figure 4 and 5 below.At first, through comprising the opened/closed mechanism of control lever 4, rocking bar 1 moves to the position that is called aligned position, and in this position, movable contact 2 electrically contacts with stationary contacts 6.Then, when two contacts 2,6 closure, the more accurately adjusting of the relative position of two contacts is following to be carried out, that is: by in hole 9 along an end in hole or the direction translation pin 8 of the other end, therefore, the drive rod 5 that depends on operating axis 3 whether respectively in the clockwise direction or mobile in the counterclockwise direction, in the counterclockwise direction or clockwise direction drive the first bar 7.
In Fig. 4, the pin 8 that is associated with the first bar 7 is positioned at one of them place, end in hole 9, angle between drive rod 5 and the second bar 10 is minimum, and this does 5 minimum movement value corresponding to driving, and therefore corresponding to operating axis 3 minimum movement value in the counterclockwise direction.
In Fig. 5,9 the other end moves pin 8 towards the hole, and this is corresponding to the maximum between drive rod 5 and the second bar 10, and therefore rotatablely moves corresponding to operating axis 3 maximum in the clockwise direction.
After this is regulated, by screw 12 being clamped in the pin 8 in order to move towards each other two parts of bar 10, obtain thus the first bar 7 on the second bar 10 clamping and the clamping in the position of pin 8 hole 9 in, execution rocking bar 1 fix in position.Thereby, by means of the present invention, the power that needs when carrying out Adjustment operation, that is: the moment of torsion that applies in the position of rocking bar 1 is substantially perpendicular to adjustment hole 9 and applies, and this power is transmitted in the position that keeps regulating.Therefore in the hole, there is very little slip stress.Thereby, after system is fixing, can not becomes unsteady by in hole 9, sliding 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 in the situation of multipole device.
The present invention never is confined to describe and illustrated execution mode naturally, and these execution modes only provide with the purpose of giving an example.On the contrary, the present invention extends to all technical equivalents and the combination thereof of containing described device, as long as the latter carries out according to marrow of the present invention.
