- the work of coupling apparatus 2 is described more fully below for making breaker 3 be automatically separated with dolly 1 and combine to separate
Make mode.
As illustrated in figures 4 a and 4b, when breaker 3 is in operating position and wishes to be automatically separated breaker 3 and dolly 1,
By handle insertion in the handle handle hole 11 on the forward face of trolley body 10, so as to insert the hand of separation-coupling apparatus
In handle patchhole 27, along the first direction of rotation R1 (in this example for counterclockwise) handle is rotated.Now, drive block 21
Projection 211 is driven through the elongated slot (not shown) of car top, and the rotation of handle is ordered about screw mandrel 22 and is rotated so that it is sheathed on silk
Drive block 21 on bar 22 drives reverse (i.e. towards testing position) translation of the breaker 3 towards first direction.When drive block 21
During close testing position, drive block 21 can be contacted with guideway 242 and connect guideway 242 by guide finger 244.With
Screw mandrel 22 is further rotated, and drive block 21 continues towards testing position to move, so as to be oriented to towards the reverse pressure of first direction
Axle sleeve 242 so that the external tooth 2421 of guideway 242 is engaged with the tooth 221 for being fixed on screw mandrel 22.After both engage, drive
Block 21 is moved together with guideway 242 and tooth 221 along the first direction of rotation R1.Now, the stage portion 2411 in fixed plate 241
The external tooth 2421 of guideway 242 can be made at a fully engaged with tooth 221.Afterwards, handle is rotated so that drive block 21 is along the first rotation
Direction R1 rotate 90 degree, drive projection 211 can depart from elongated slot and drive block 21 arrival separation point position, so as to breaker 3 with it is little
Car 1 is separated.
When breaker 3 is in testing position and hope is automatically combined breaker 3 with dolly 1, now at drive block 21
In separation point position as shown in Figure 2, handle is rotated, make drive block 21 (for example, suitable along the direction contrary with the first direction of rotation R1
Clockwise) it is rotated by 90 ° to binding site.Now, the driving projection 211 on drive block 21 is engaged in elongated slot, and due to
The effect of torsion spring 25, tooth 221 is disengaged from so as to separate with the external tooth 2421 on guideway 242.Handle is rotated further, due to
Projection 211 is driven to be engaged in elongated slot so that axis in the first direction P1 direction examination of the drive block 21 after separating along screw mandrel 22
Test position to do translational motion and do not rotate.The foregoing describe the device for making breaker and dolly be automatically separated and combine.
Although the better model to performing the present invention has carried out detailed description, those skilled in the art can obtain
Know many alternative designs and embodiment for implementing the present invention within the scope of the appended claims.
