The transmission member 3 includes a push rod contact portion 9 that is always in contact with the release push rod 7 and is used to push the circuit breaker when the circuit breaks down. The drawbar pushing part 10 of the drawbar 8, the transmission part 3 can rotate freely, the return spring 4 is relatively fixed on the transmission part 3, one end is connected on the transmission part 3, and the other end is connected on the shell 1, and the return spring 4 always makes the The transmission member 3 is in contact with the push rod 7 of the release.
本发明实施例结构如图1所示，其装配结构如图2和图3所示。 The structure of the embodiment of the present invention is shown in FIG. 1 , and its assembly structure is shown in FIG. 2 and FIG. 3 .
该实施例中，采用一个如图6所示的压板2与外壳1底部相配合形成一个空腔，形成空腔的方式可以是仅在压板底部开槽，也可以是仅在外壳底部开槽，但最好是在压板底部和外壳底部同时设置半圆弧状的凹槽（如图4和图6所示），二者拼合后共同形成一个空腔。与之相配合，传动件3上可设置凸起11或转动轴或其它轴状结构，本实施例仅以设置凸起11的情况进行说明。传动件上3的凸起11设置于空腔内，与空腔配合，可实现传动件3的轴向定位。该空腔优选为圆柱形，圆柱形空腔与传动件3为间隙配合，使传动件3可灵活转动。 In this embodiment, a pressure plate 2 as shown in FIG. 6 is used to cooperate with the bottom of the housing 1 to form a cavity. The cavity can be formed by slotting only at the bottom of the pressure plate or only at the bottom of the housing. But it is better to set semi-arc grooves (as shown in Figure 4 and Figure 6 ) at the bottom of the pressing plate and the bottom of the shell at the same time, and form a cavity together after the two are put together. Correspondingly, the transmission member 3 may be provided with a protrusion 11 or a rotating shaft or other shaft-like structures, and this embodiment is only described with the case of providing the protrusion 11 . The protrusion 11 on the transmission part 3 is arranged in the cavity, and cooperates with the cavity to realize the axial positioning of the transmission part 3 . The cavity is preferably cylindrical, and the cylindrical cavity is in clearance fit with the transmission member 3 so that the transmission member 3 can rotate flexibly.
传动件3的优选结构如图5所示，其推杆接触部9和牵引杆推动部10为两端呈圆弧面的柱状结构，其中，推杆接触部9的圆弧面始终与脱扣器推杆7相接触配合。 The preferred structure of the transmission part 3 is shown in Figure 5, the push rod contact part 9 and the draw bar push part 10 are columnar structures with two ends being arcuate surfaces, wherein the arcuate surface of the push rod contact part 9 is always in contact with the tripping The device push rod 7 is in contact with each other.
本发明的工作过程如下： Working process of the present invention is as follows:
当断路器正常工作时，脱扣器传动装置的状态如图7所示。传动件3的推杆接触部9在复位弹簧4的作用下稳定倚靠在脱扣器推杆7的一侧。 When the circuit breaker is working normally, the state of the release device transmission is shown in Figure 7. The push rod contact portion 9 of the transmission member 3 leans against one side of the release push rod 7 stably under the action of the return spring 4 .
当电路发生故障时，脱扣器将动作，其中脱扣器致动件6将绕中心O1转动，并带动脱扣器推杆7移动，脱扣器推杆7的杆臂作用在传动件3的推杆接触部9上，使传动件3绕中心O2转动。随着传动件3的传动，传动件3的牵引杆推动部10位置发生变化，如图8所示。同时，传动件3的牵引杆推动部10推动断路器牵引杆8，断路器牵引杆8将绕其转动中心O3转动，触发断路器的机构动作，最终断路器分断电路。 When the circuit breaks down, the tripper will act, wherein the tripper actuating part 6 will rotate around the center O1, and drive the tripper push rod 7 to move, and the lever arm of the tripper push rod 7 acts on the transmission part 3 on the push rod contact portion 9, so that the transmission member 3 rotates around the center O2 . With the transmission of the transmission member 3, the position of the traction rod pushing portion 10 of the transmission member 3 changes, as shown in FIG. 8 . At the same time, the drawbar pushing part 10 of the transmission part 3 pushes the breaker drawbar 8, and the breaker drawbar 8 will rotate around its rotation center O3 , triggering the action of the mechanism of the breaker, and finally the breaker breaks the circuit.
虽然本发明已以较佳实施例公开如上，但实施例并不用来限定本发明。在不脱离本发明之精神和范围内，所做的任何等效变化或润饰，同样属于本发明之保护范围。因此本发明的保护范围应当以本申请的权利要求所界定的内容为标准。 Although the present invention has been disclosed above with preferred embodiments, the embodiments are not intended to limit the present invention. Any equivalent changes or modifications made without departing from the spirit and scope of the present invention also belong to the protection scope of the present invention. Therefore, the scope of protection of the present invention should be based on the content defined by the claims of this application.
