Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker opening and closing, in particular to a circuit breaker operating mechanism. Background Art

[0002] A circuit breaker is a switching device that can close, carry and disconnect current under normal circuit conditions and can close, carry and disconnect current under abnormal circuit conditions within a specified time. During the opening and closing process of the circuit breaker, the circuit breaker handle on the circuit breaker needs to be manually turned to increase safety when turning the circuit breaker handle.

[0003] Therefore, the circuit breaker opening and closing operating mechanism of the prior art has a publication number of CN212209390U. When the circuit breaker is installed and used, the circuit breaker is installed in an explosion-proof electrical appliance, and the opening and closing operating mechanism is installed on the box cover, so that the clamping sleeve is sleeved on the circuit breaker handle of the circuit breaker. During operation, the operating handle is rotated to rotate the transmission shaft, thereby driving the transmission slide plate and the clamping sleeve to move along the length direction of the guide rod, and driving the circuit breaker handle to move.

[0004] However, when the prior art is used, the rotational force generated by the rotating handle is directly converted into the rotational force of the transmission shaft, but the rotation of the transmission shaft drives the transmission slide plate and the ferrule to slide horizontally, that is, the rotational force is converted into a linear force. Because the direction of the line of action of the force changes, when the magnitude or direction of the force changes, it will affect the external effect of the force on the circuit breaker handle.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] like Figure 1-5As shown, the circuit breaker operating mechanism includes a circuit breaker body 1 and a circuit breaker handle 3 on the circuit breaker body 1. The circuit breaker body 1 is a circuit breaker known on the market, so the internal structure and wiring diagram are known and do not need to be described in detail. A sliding plate 4 is installed on the circuit breaker body 1. The sliding plate 4 is arranged close to the circuit breaker handle 3, and a slot 14 is opened on the side of the sliding plate 4. The sliding plate 4 is fixedly connected to a connecting frame 6 on the side facing away from the circuit breaker handle 3. The inner wall of the connecting frame 6 is slidably connected to a slider 7 extending into the slot 14. The slider 7 moves along the circuit breaker. The handle 3 slides in the toggle direction, and a bolt 8 is threadedly inserted on the side of the slider 7. The end face of the bolt 8 is fixedly connected with a lever 13 for toggling the circuit breaker handle 3. The bolt 8 and the slider 7 are disassembled by machining a threaded hole on the side of the slider 7 and threadedly connected with the bolt 8 by the threaded hole. In addition, the lever 13 at the end of the bolt 8 is slidably connected with the inner wall of the threaded hole opened on the slider 7. Therefore, after the bolt 8 is disengaged from the slider 7, the slider 7 can be directly withdrawn. After the lever 13 is no longer in contact with the side of the circuit breaker handle 3, the slider 7 can be adjusted. The position of the lever 13 is adjusted after the lever 13 is reinstalled. The top and bottom sides of the connecting frame 6 are provided with a slide groove 9. The top and bottom sides of the slider 7 are integrally formed with a T-shaped protrusion that is slidably connected to the inner wall of the slide groove 9. The T-shaped protrusion is used to ensure that the slider 7 can only slide in the slide groove 9. Therefore, when the slider 7 slides, the bolt 8 and the lever 13 are driven to slide. The lever 13 is used to resist the circuit breaker handle 3, so that the lever 13 pushes the circuit breaker handle 3 to move, so that the circuit breaker handle 3 is moved to the circuit breaker body 1. On the other hand, when resetting the circuit breaker handle 3, it is only necessary to rotate the bolt 8 until the bolt 8 is disengaged from the slider 7, and then the lever 13 can be directly pulled out, and then the slider 7 can be slid to the other side of the circuit breaker handle 3, and then the lever 13 can be inserted into the slider 7 until the bolt 8 is re-threaded in the slider 7, so that the lever 13 can be adjusted to the other side of the circuit breaker handle 3, and the slider 7 can be moved in the reverse direction to realize that the lever 13 pushes the circuit breaker handle 3 to be reset. In addition, the lever 13, the bolt 8, the slider 7 and the sliding plate 4 are all made of insulating materials.

[0024] Further discussion: The two ends of the bottom edge of the sliding plate 4 facing away from the circuit breaker handle 3 are penetrated and fixedly connected with an extension frame 10, and a connecting column 5 is inserted in the extension frame 10. The two ends of the connecting column 5 are detachably connected with side brackets 2 for fixing on both sides of the circuit breaker body 1. The side brackets 2 are sleeved on the connecting column 5, and the two connecting columns 5 are arranged in parallel. Arc grooves 12 are opened at the edges of the connecting column 5, and the several arc grooves 12 on the connecting column 5 are concentric and have the same arc. The arc surface part of the arc groove 12 is processed with a threaded groove, and the end face of the extension frame 10 is rotatably connected with a nut 11 threadedly connected to the arc groove 12, and a fixing pin 15 threadedly connected to the side of the circuit breaker body 1 is penetrated by the side of the side bracket 2, and a nut 11 threadedly connected to the groove surface of the arc groove 12 is also provided on the side bracket 2. Specifically, the connecting column 5 can be made of plastic material, so it can be adjusted according to the circuit breaker. The connecting column 5 is cut according to the width of the circuit breaker body 1, and then the side bracket 2 is fixed to the side of the circuit breaker body 1 by using the fixing pin 15, and the two side brackets 2 are aligned during the installation process, and the sliding plate 4 is placed on the circuit breaker handle 3 of the circuit breaker body 1, and the connecting column 5 passes through the side bracket 2 on one side, then passes through the extension frame 10, and finally passes through the side bracket on the other side, and then the nut 11 is installed on the side bracket 2, and the threaded connection between the nut 11 and the arc groove 12 is used to fix the relative position of the connecting column 5 and the side bracket 2, and when the connecting column 5 passes through the extension frame 10, the nut 11 on the extension frame 10 is rotated, so that the extension frame 10 can drive the sliding plate 4 to move on the connecting column 5, that is, the position of the sliding plate 4 can be adjusted according to the position where the circuit breaker handle 3 is installed on the circuit breaker body 1, to ensure that the lever 13 smoothly fits one side of the circuit breaker handle 3.

[0025] Working principle: according to the width of the circuit breaker body 1, the connecting column 5 is cut into the corresponding length, the side brackets 2 are aligned and fixed on both sides of the circuit breaker body 1, the sliding plate 4 is installed on the circuit breaker body 1, and then the connecting column 5 is fixed to the circuit breaker body 1 through the nuts 11 on the side brackets 2, and the position of the sliding plate 4 is adjusted again using the nuts 11 on the extension frame 10 until the lever 13 moves to the circuit breaker handle 3. When in use, the slider 7 slides to drive the bolt 8 and the lever 13 to slide, and the lever 13 is used to push the circuit breaker handle 3 to move, so that the circuit breaker handle 3 is moved to the other side of the circuit breaker body 1.
