Torsion spring 7 resets, and the first torsion spring 7 is mounted on the rocking arm set 201 stretched out on rocking arm 2, and one end is mounted in the hole 1 on rocking arm 2, separately
One end props up the surface of support 1.The cam arm 4 is resetted by the second torsion spring 8, and second torsion spring 8 is mounted on axle sleeve 13, one end
In being inserted into the hole 2 101 of support 1, the other end is hung on cam arm 4, and the axle sleeve 13 is sleeved on the second rivet shaft 5.Rocking arm
2 are connected with pull bar 10, drive pull bar 10 to move up and down in the swing process of rocking arm 2, and the one end of the pull bar 10 is mounted in connecting shaft 12,
The other end passes through support 1, the connecting shaft 12 to be installed in the mounting hole 204 of rocking arm 2, and connecting shaft 12 is spacing with jump ring 11.
Pull bar 10 stretches into corresponding with trip shaft 9 in chopper.
The support 1 is provided with limited post 6, can limit the swing position of cam arm 4.
The rivet shaft 5 of first rivet shaft 3 and second is installed on support 1.
Specifically, as shown in Figure 6, the cam arm 4 includes cam 401 and cam lever 402, the drive on cam 401
Dynamic face 401a is contacted with the linkage post 203 stretched out on rocking arm 2, and drive surface 401a includes successively the first drive surface 401a01,
Second drive surface 401a02 and the 3rd drive surface 401a03, in the swing process of cam arm 4, the first drive surface 401a01, second drives
Dynamic face 401a02 and the 3rd drive surface 401a03 are contacted successively with linkage post 203, rocking arm 2 in the first drive surface 401a01, second
Drive surface 401a02 and the 3rd drive surface 401a03 and the first torsion spring 7 swing back and forth under acting on.First drive surface 401a01
Rocking arm 2 can be driven for inclined-plane, the mounting hole 204 for making rocking arm 2 is rotated down, second drive surface 401a02 can for cambered surface
Make the holding position of rocking arm 2, the 3rd drive surface 401a03 to drive rocking arm 2 for inclined-plane, make the mounting hole 204 of rocking arm 2 to
Lower rotation.
The course of work of the present utility model is：Such as accompanying drawing 2, shown in accompanying drawing 7 and accompanying drawing 8, when cam arm 4 is subject to external force
When, cam arm 4 is withstood at the limited post 6 of support 1 by the power of the second torsion spring 8, cam lever 402, and now, rocking arm 2 receives the first torsion spring 7
Power, linkage post 203 withstood in the first drive surface 401a01, and the mounting hole 204 on rocking arm 2 is in extreme higher position, pull bar 10
End face is in extreme higher position.
Start to rotate when cam arm 4 is subject to external force, the first drive surface 401a01 of cam arm 4 promotes linkage post 203, makes
Rocking arm 2 is rotated, and the mounting hole 204 on rocking arm 2 is rotated down, and the end face for driving pull bar 10 is moved down.
When cam arm 4 is rotated further, cam arm 4 continues to press on rocking arm 2 and rotates, when the second drive surface of cam arm 4
When the linkage post 203 of 401a02 and rocking arm 2 is contacted, rocking arm 2 turns to maximum angle, and the mounting hole 204 on rocking arm 2 is moved to most
Lower position, the end face for driving pull bar 9 is in extreme lower position.In the process that the second drive surface 401a02 and linkage post 203 are contacted
In, the position of mounting hole 204 keeps constant, and the endface position of pull bar 10 keeps constant.
When cam arm 4 continues to rotate to maximum angle, the linkage post 203 of rocking arm 2 departs from the second drive surface of cam arm 4
401a02, rocking arm 2 is rotated in the presence of the first torsion spring 7, and the linkage post 20 for making rocking arm 2 is against in the 3rd drive surface 401a03,
The mounting hole 204 of rocking arm 2 is moved upwards, is returned to extreme higher position, and the end face for driving pull bar 10 is returned to extreme higher position.
After cam arm 4 turns to maximum angle, if external force disappears, cam arm 4 is reverse in the presence of the second torsion spring 8
Rotate, the 3rd drive surface 401a03 of cam arm 4 promotes the linkage post 203 of rocking arm 2, rotates rocking arm 2, the kidney-shaped on rocking arm 2
Hole 204 rotates down, and the end face for driving pull bar 10 is moved down.
When cam arm 4 continues to rotate backward, when the linkage post 203 of the second drive surface 401a02 and rocking arm 2 is contacted, shake
Arm 2 turns to maximum angle, and the mounting hole 204 on rocking arm 2 moves to lowermost position, drives the end face of pull bar 10 in minimum
Position.During the second drive surface 401a02 and linkage post 203 are contacted, the position of mounting hole 204 keeps constant, so drawing
The position of the end face of bar 10 keeps constant.
When cam arm 4 continues to rotate backward, rocking arm 2 receives the power of the first torsion spring 7, linkage post 203 to withstand on the first drive surface
On 401a01, the mounting hole 204 on rocking arm 2 is rotated up, and the end face for driving pull bar 10 is moved up.When the cam of cam arm 4
When bar 402 withstands on the limited post 6 of support 1, cam arm 4 stops operating, and now, the mounting hole 204 on rocking arm 2 is in highest order
Put, the end face for driving pull bar 10 is in extreme higher position.
When chopper is in combined floodgate or buckle-like state again, trip shaft 9 is in position shown in accompanying drawing 9；When chopper is in de-
During buckle-like state, trip shaft 9 be in position shown in Figure 10, relative to close a floodgate or again buckle-like state when, trip shaft 9 have rotated certain angle
Degree.
When interlocking mechanism pull bar 10 not by 2 pulled down of rocking arm when, i.e., interlocking mechanism be in Fig. 2, Fig. 8, Fig. 9 and Figure 10
State, chopper in closing a floodgate, detain again or during trip status, trip shaft 9 not with the end contact of pull bar 10, so breaking
The state of device is not affected by interlocking mechanism.When pull bar 10 is by 2 pulled down of rocking arm, if chopper is in combined floodgate or again buckle-like
State, the end face of pull bar 10 will promote trip shaft 9 in folding process, make circuit breaker tripping.
As shown in figure 9, when chopper is initially inserted into socket under "on" position, the end face of pull bar 10 will be in folding process
Trip shaft 9 is promoted, circuit breaker tripping is made.
As shown in Figure 10, when chopper starts to extract socket under "on" position, the end face of pull bar 10 will be in folding process
Middle promotion trip shaft 9, makes circuit breaker tripping.
The plug-in moulded case circuit breaker interlock that this utility model is provided, employs the form of integral installation, installs letter
Single, Reliability of Microprocessor is high, and whole interlock cam arm can be rotation, when chopper is not inserted into bearing, cam arm height
Highest, but during insertion socket, with the rotation of cam arm, the height of cam arm is gradually reduced, so relative to biography
It is less demanding to receptacle face spatial depth for the interlock of system.Overcoming existing circuit breaker interlocking device needs socket
There is deeper space to meet the needs installed and move.
