Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes, structures, mutual positions and connection relations of the components, the functions and operation principles of the components, and the like:

as shown in fig. 1 and 2, the utility model relates to a circuit breaker separating brake pawl part mounting structure, including frock riser 1, frock bottom plate 2, frock dog 3, frock riser 1 arranges with frock bottom plate 2 is perpendicular, and frock dog 3 is located 1 one side lateral part position of frock riser. The circuit breaker opening latch component comprises a large latch 4, a small latch 5, a torsion spring a6, a torsion spring b7, a connecting shaft 8 and a connecting pin 9. The large pawl 4 and the small pawl 5 of the circuit breaker opening pawl component mounting structure are connected through a connecting pin 9, a torsion spring b7 is sleeved on the connecting pin 9, a connecting shaft 8 penetrates through the small pawl 5, and a torsion spring a6 is sleeved on the connecting shaft 8. The above structure is used for mounting the opening latch member of the circuit breaker, especially because the two torsion springs have overlapping problem. Before installing, to assembling frock riser, frock base, frock dog (bolted connection or welding all can) to form an installation frock, then install according to the step: connect together torsion spring b messenger's little sincere son and big sincere son through the connecting pin earlier, put big sincere son on the frock dog again, realize the location of big sincere son through the cooperation of frock riser and the frock dog that is located frock riser middle part position. Then, lean on in torsional spring b one end through frock riser upper end top, realize torsional spring b one end and block for there is certain clearance between torsional spring b and the torsional spring a of dress on the connecting axle, and torsional spring a is connected with big sincere son and little sincere son respectively, like this, just can freely install the connecting axle and pass the macropore on the big sincere son, release torsional spring b one end on torsional spring a again at last, just accomplished the assembly of separating brake part. Therefore, the problem that torsion needs to be overcome to facilitate installation due to superposition interference of the two torsion springs does not exist in the whole installation process, the installation process is effectively simplified, and the labor intensity during installation is reduced. Breaker separating brake pawl part mounting structure, simple structure can accomplish the installation of big sincere son (the sincere son of big separating brake), the sincere son of little sincere son (the sincere son of little separating brake) conveniently laborsavingly, need not use very big power to overcome the torsion of torsional spring, intensity of labour when reducing the operation improves assembly efficiency.

When the large pawl 4, the small pawl 5, the torsion spring a6, the torsion spring b7, the connecting shaft 8 and the connecting pin 9 of the breaker opening pawl component are installed, the large pawl 4 is arranged to be positioned at the position of the tool vertical plate 1 and the position of the tool stop 3. When the large latch 4 is positioned at the positions of the tooling vertical plate 1 and the tooling stop dog 3, the end a10 of the torsion spring b7 of the breaker opening latch part is set to be a structure which can abut against the position of the vertical plate inclined plane 11 at the upper end of the tooling vertical plate 1. Above-mentioned structure through the riser inclined plane of frock riser upper end, can play limiting displacement to torsional spring b one end, avoids it to fall to take place the coincidence and interfere with torsional spring a, improves the installation convenience. And after the torsion spring a is installed, the torsion spring b is released, and the original limited end of the torsion spring b is pressed on the torsion spring, so that accurate installation is realized. Thus, when two torsion springs are installed, the problem of mutual superposition interference can not occur.

When the large latch 4 is positioned at the position of the tooling vertical plate 1 and the tooling stop dog 3, the end b12 of the torsion spring b7 of the breaker opening latch component is arranged to be capable of abutting against the connecting shaft 8. The end a13 of the torsion spring a6 of the circuit breaker opening latch component is configured to abut against the positioning hole a14 on the large latch 4. The end b15 of the torsion spring a6 of the circuit breaker trip pawl member is configured to abut against the positioning hole b16 of the small pawl 5. According to the structure, after the components of the breaker opening pawl component are installed, the two ends of each torsion spring are respectively limited at the corresponding positions, so that reliable installation is realized, and reliable work can be realized. And then the circuit breaker opening latch component is detached from the tool.

The present invention has been described in detail with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and the present invention can be implemented in various ways without modification, and the present invention is not limited by the above embodiments.
