Description

Technical Field

[0001] This utility model relates to the field of circuit breaker switch lever technology, and more specifically, to a positioning structure for a circuit breaker switch lever. Background Technology

[0002] Circuit breaker switch levers, also known as insulating levers or link bars, are insulating tools specifically designed for high-voltage circuit equipment. They are primarily used for closing or opening high-voltage disconnect switches, installing or removing portable grounding wires, and performing measurements and tests. These levers typically consist of three parts: a working head, an insulating rod, and a handle. This ensures that operators can work on high-voltage equipment from a safe distance. During manufacturing, circuit breaker switch levers require precise positioning to ensure that their dimensions meet design requirements. Accurate positioning helps prevent deviations during processing, guaranteeing that the lever's geometry and dimensions meet usage requirements.

[0003] A search revealed that Chinese Patent CN215527658U discloses a switch-pushing device for a circuit breaker. This utility model's switch-pushing device is installed on the circuit breaker and includes a pull rod and an arc-shaped track. The arc-shaped track is located on the side of the circuit breaker. One end of the pull rod has a slider, which is installed in the arc-shaped track and can move along the track. The other end of the pull rod has a latch, which is nested in the switch handle of the circuit breaker and is hinged to the pull rod. This utility model makes it more convenient and faster to operate the control switch, and the user does not directly contact the switch, thus improving the safety of operation.

[0004] During the production and processing of the aforementioned circuit breaker switch levers, the levers are generally positioned once. When multiple levers need to be adjusted or replaced, the operator must position and operate them one by one, which greatly increases the workload and time cost. At the same time, when positioning a single lever, it is difficult to ensure that the positioning of all levers is completely consistent, thus making it difficult to guarantee the quality of the levers. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a positioning structure for a circuit breaker switch lever, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for a circuit breaker switch lever, comprising a mounting plate, a positioning groove on the mounting plate, a lever body movably disposed inside the positioning groove, a horizontal plate on the top of the mounting plate, a sliding groove on the horizontal plate, and a positioning component and a connecting component disposed between the horizontal plate and the mounting plate, the positioning component comprising a first screw and two first nuts, and the connecting component comprising a second screw, a second nut, a connecting plate, a threaded rod, and a plug rod.

[0007] Furthermore, the bottom end of the first screw passes through the groove, and both first nuts are movably sleeved on the first screw, with the opposite sides of the two first nuts contacting the horizontal plate.

[0008] Furthermore, the bottom end of the second screw passes through the groove and the insert rod, and the second screw is threadedly connected to the mounting plate. The second nut is movably sleeved on the second screw, and both ends of the connecting plate are fixedly connected to the threaded rod and the insert rod, respectively.

[0009] Furthermore, three washers are movably fitted on the second screw, and one side of each of the three washers contacts the second screw, the cross plate, the second nut, and the mounting plate, respectively.

[0010] It can be seen that the above technical solution aims to improve the stability between the second screw, the cross plate, the second nut, and the mounting plate.

[0011] Furthermore, the number of mounting plates, positioning slots, horizontal plates, positioning components, and connecting components is several, and adjacent mounting plates are connected by connecting components.

[0012] It can be seen that the above technical solution is designed to facilitate the simultaneous positioning of multiple tie rod bodies.

[0013] Furthermore, one end of the threaded rod extends into and is threadedly connected to one of the mounting plates.

[0014] Furthermore, one end of the insert extends into the interior of another mounting plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention fixes the cross plate, mounting plate, and insert rod by rotating the insert rod and extending the threaded rod into the interior of the mounting plate. Then, the two mounting plates are brought together, and the second screw is rotated and moved into the insert rod, thereby fixing the cross plate, mounting plate, and insert rod together. Similarly, multiple mounting plates can be installed. The first screw can be used to position the main body of the pull rod, allowing multiple pull rod bodies to be positioned simultaneously, effectively reducing workload and time costs, while ensuring that the positioning of all pull rod bodies is completely consistent.

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Refer to the instruction manual appendix Figure 1-5 The positioning structure of a circuit breaker switch lever in this embodiment includes a mounting plate 1, a positioning groove 2 on the mounting plate 1, a lever body 3 movably disposed inside the positioning groove 2, a horizontal plate 4 on the top of the mounting plate 1, a sliding groove 5 on the horizontal plate 4, and a positioning component 6 and a connecting component 7 disposed between the horizontal plate 4 and the mounting plate 1. The positioning component 6 includes a first screw 601 and two first nuts 602, and the connecting component 7 includes a second screw 701, a second nut 702, a connecting plate 704, a threaded rod 705, and a plug rod 706.

[0026] Furthermore, the bottom end of the first screw 601 passes through the slide groove 5, and both first nuts 602 are movably sleeved on the first screw 601, with the opposite sides of the two first nuts 602 contacting the horizontal plate 4. The bottom end of the second screw 701 passes through the slide groove 5 and the insert rod 706, and the second screw 701 is threadedly connected to the mounting plate 1. The second nut 702 is movably sleeved on the second screw 701. The two ends of the connecting plate 704 are fixedly connected to the threaded rod 705 and the insert rod 706, respectively. Three washers 703 are movably sleeved on the second screw 701, and one side of each of the three washers 703 contacts the second screw 701, the horizontal plate 4, the second nut 702, and the mounting plate 1, respectively.

[0027] Furthermore, there are several mounting plates 1, positioning grooves 2, horizontal plates 4, positioning components 6 and connecting components 7, and two adjacent mounting plates 1 are connected by connecting components 7. One end of the threaded rod 705 extends into the interior of one of the mounting plates 1 and is threadedly connected to it, and one end of the insertion rod 706 extends into the interior of the other mounting plate 1.

[0028] The usage method of this embodiment is as follows:

[0029] In use, the operator rotates the insert rod 706, causing the threaded rod 705 to extend into the interior of the mounting plate 1, thereby fixing the insert rod 706 to the mounting plate 1. Then, the two mounting plates 1 are brought together, and the insert rod 706 is inserted into the interior of another mounting plate 1. The second screw 701 is then passed through the sliding groove 5, and the second screw 701 is rotated to move into the insert rod 706, thereby fixing the cross plate 4, the mounting plate 1, and the insert rod 706 together, thus fixing the two mounting plates 1. Multiple mounting plates 1 are installed in the same way. The pull rod body 3 is placed into the positioning groove 2, and the first nut 602 is rotated away from the first screw 601, thereby releasing the first screw 601. The first screw 601 is fixed to the horizontal plate 4 by vertically moving the first screw 601 and adjusting its position on the horizontal plate 4. Similarly, the first screw 601 is fixed to the horizontal plate 4 by the two first nuts 602. The first screw 601 can be used to position the pull rod body 3. Multiple pull rod bodies 3 can be positioned simultaneously, which effectively reduces the workload and time cost. At the same time, it can ensure that the positioning of all pull rod bodies 3 is completely consistent. The distance between the horizontal plate 4 and the mounting plate 1 can be adjusted by the second nut 702. The stability between the second screw 701, the horizontal plate 4, the second nut 702 and the mounting plate 1 can be improved by the three washers 703.
