[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions and closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Outdoor circuit breakers are particularly suitable for rural power grids and locations requiring frequent operation. One existing type of outdoor circuit breaker and its transmission device are located at the bottom of the enclosure. During assembly, commissioning, and mechanical characteristic testing, the enclosure must be inverted. Furthermore, in some testing phases, the circuit breaker needs to be flipped to meet the testing conditions.
[0003] To address this, some assembly fixtures have emerged on the market that can enable outdoor circuit breakers to flip. These fixtures often use limit pins and sockets on the rotating structure to fix the flip angle of the circuit breaker. This results in a relatively fixed adjustment unit and low adjustment accuracy when adjusting the flip angle of the circuit breaker. In actual assembly of outdoor circuit breakers, there may be situations where the required rotation angle cannot be fully matched. Furthermore, the matching method of the limit pins and sockets is prone to jamming, making adjustment difficult.
[0004] Therefore, there is an urgent need for a tooling that can maintain the rotation angle of outdoor circuit breakers, has a simple adjustment method, and high adjustment accuracy. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0030] This utility model provides a tooling for outdoor circuit breakers, such as... Figures 1-3As shown, the fixture includes a base 1, a mounting bracket, a mounting plate 3, and a rotary braking assembly 4. The mounting bracket includes a first bracket 21 and a second bracket 22, which are spaced apart on the base 1 along a first direction, and the distance between the first bracket 21 and the second bracket 22 is adjustable. The mounting plate 3 is rotatably mounted on the mounting bracket and is used to connect with the circuit breaker. The rotary braking assembly 4 is mounted on the mounting bracket and is connected to the mounting plate 3 in a transmission manner. The rotary braking assembly 4 can drive the mounting plate 3 to rotate and can maintain the rotation angle of the mounting plate 3. The fixture for outdoor circuit breakers of this utility model achieves adaptation to different models of circuit breakers by setting the first bracket 21 and the second bracket 22 with an adjustable distance on the base 1. The rotary braking assembly 4 drives the mounting plate 3 to rotate, thereby realizing the flipping of the circuit breaker, and can also maintain the rotation angle of the mounting plate 3 and the circuit breaker in real time, without being limited by the socket spacing, greatly simplifying the adjustment method of the circuit breaker rotation angle, and having high adjustment accuracy. It is understood that there are two mounting plates 3, which are respectively mounted on the first bracket 21 and the second bracket 22, and the two mounting plates 3 are symmetrically arranged to support and install the circuit breaker. For ease of installation, the mounting plate 3 is configured as an L-shaped plate, including a first part extending along a first direction and a second part extending along a second direction. One end of the second part is rotatably connected to the mounting bracket, and the other end is fixedly connected to the second part.
[0031] In some embodiments, at least one of the first bracket 21 and the second bracket 22 is adjustablely disposed on the base 1. It is understood that only the position of either the first bracket 21 or the second bracket 22 relative to the base 1 needs to be adjustable to achieve the tooling of the present invention for outdoor circuit breakers to adapt to circuit breakers of different sizes. In order to further improve the applicability of the tooling of the present invention for outdoor circuit breakers without excessively increasing the structural size, both the first bracket 21 and the second bracket 22 can be adjustablely disposed on the base 1 along the first direction.
[0032] In some embodiments, the tooling for outdoor circuit breakers of this invention further includes an adjustment component 5, which is used to adjust the gap between the first bracket 21 and the second bracket 22. It is understood that using the adjustment component 5 to adjust the gap between the first bracket 21 and the second bracket 22 can minimize structural changes to the mounting bracket and save on product manufacturing costs.
[0033] In some specific embodiments, such as Figures 1-3As shown, the adjustment assembly 5 includes a base plate 51, which is mounted on the base 1. A slide rail 511 extending along a first direction is provided on the base plate 51. A groove is provided at the bottom end of either the first bracket 21 or the second bracket 22. The groove cooperates with the slide rail 511 to allow the first bracket 21 or the second bracket 22 to slide along the first direction. It is understood that the cooperation between the groove and the slide rail 511 is simple and easy to use; simply pushing or pulling the first bracket 21 or the second bracket 22 along the first direction adjusts the distance between them, adapting to different types of circuit breakers. To prevent the first bracket 21 or the second bracket 22, which is slidably connected to the base plate 51, from disengaging from the base 1, both the groove and the slide rail 511 are T-shaped, ensuring that they slide smoothly without disengaging. Furthermore, since the mounting plate 3 is fixedly connected to the circuit breaker during installation, threaded holes can be provided on the mounting plate 3, matching the mounting holes on the circuit breaker base 1. The circuit breaker is then fixed to the mounting plate 3 using bolts. Once the circuit breaker is installed, the first bracket 21 or the second bracket 22, which can slide relative to the base plate 51, is simultaneously fixed, naturally eliminating the need for additional fasteners. In some optional embodiments, the relative position between the base plate 51 and the base 1 is adjustable, thereby further increasing the applicability of this utility model for the tooling of outdoor circuit breakers.
[0034] In some alternative embodiments, such as Figure 1 and Figure 3 As shown, to prevent the adjustable first bracket 21 and second bracket 22 from moving freely when not in use, and to facilitate circuit breaker installation, the adjustment assembly 5 also includes a tongue plate 52. The tongue plate 52 is rotatably connected to the first bracket 21 or the second bracket 22. A positioning plate 53 is also provided on the base plate 51. The positioning plate 53 has multiple positioning slots. In use, the tongue plate 52 can be moved and rotated to engage with any one of the positioning slots, thereby fixing the position of the first bracket 21 or the second bracket 22. It is understood that by setting the tongue plate 52 and the positioning plate 53 to fix the position of the adjustable first bracket 21 or the second bracket 22, the circuit breaker can be installed more conveniently and effortlessly. No manual maintenance is required; the circuit breaker is simply placed on the first part of the mounting plate 3, and then only the position of the circuit breaker needs to be adjusted and fixed. The assembly structure of the circuit breaker and the tooling of this utility model for outdoor circuit breakers is as follows: Figure 4 and Figure 5 As shown, where, Figure 4 neutralization Figure 5 The position can be considered as the initial position after the circuit breaker is installed, or it can be considered as... Figure 5 yes Figure 4 The position of the circuit breaker after flipping 180 degrees. In other embodiments, the tongue plate 52 may also be movably connected in the second direction, i.e., configured as a latch lock.
[0035] In some embodiments, such as Figure 1 and Figure 2 As shown, the rotary brake assembly 4 includes a reducer 41. The output end of the reducer 41 is connected to the mounting plate 3, and the input end of the reducer 41 is connected to a crank handle or a drive component. It is understood that by setting the reducer 41, the drive load can be greatly reduced, facilitating the rotational adjustment of the circuit breaker angle. It can also be manually operated using the crank handle 42, making it convenient to use without a drive component, or connected to a drive component when one is available, requiring less effort. To facilitate switching power sources, the input end of the reducer 41 is equipped with rotating locking arms that are respectively connected to the crank handle 42 and the drive component, and are respectively located on both sides of the reducer 41. When connected to the drive component, it is not necessary to disassemble the crank handle 42. Furthermore, to ensure the circuit breaker maintains its rotation angle in real time without adjustment, this embodiment employs a high-ratio reducer 41. This makes it difficult for the mounting plate 3 on one side of the reducer 41's output end and the circuit breaker to overcome the internal frictional resistance generated by the reducer 41's structure. Thus, without adjustment, the circuit breaker's rotation angle is maintained by utilizing the reducer 41's high reduction ratio. In some specific embodiments, the reducer 41 is a worm gear reducer, which has good mechanical self-locking performance, preventing reverse rotation. After the circuit breaker's angle is adjusted, the rotation angle can be maintained, with a reversible angle approaching 180 degrees, and it offers high reliability.
[0036] In some optional embodiments, the rotary braking assembly 4 further includes a rotary damper (not shown in the figure). The mounting plate 3 and the circuit breaker maintain their rotation angle through the rotary damper. It is understood that by using a rotary damper and setting its resistance to be greater than the weight of the circuit breaker and the mounting plate 3, the rotation angle can be kept fixed even when disconnected from the drive source during circuit breaker rotation angle adjustment, achieving real-time position fixation. The damper can be disposed between the reducer 41 and the mounting plate 3 and drivenly connected to both the reducer 41 and the mounting plate 3 respectively. The use of the damper can reduce the cost requirements of the reducer 41.
[0037] In some optional embodiments, the rotary braking assembly 4 further includes a friction brake (not shown in the figure). The mounting plate 3 and the circuit breaker maintain their rotation angle through the friction brake. It is understood that by using a friction brake, and braking the input shaft of the reducer 41 at its input end when disconnected from the drive source (and of course, braking the output end of the reducer 41), the rotation angle can be kept fixed, thereby achieving a fixed rotation angle for the circuit breaker. Furthermore, friction brake technology is relatively mature, low in cost, and easy to use.
[0038] In some embodiments, in order to ensure the safety and reliability of the circuit breaker during rotation, the reducer 41, the rotary damper and the friction brake can be used in any combination, without any specific restrictions.
[0039] In some embodiments, such as Figure 1 and Figure 3 As shown, the mounting bracket is equipped with a rotating shaft 23 and a bushing 24. The rotating shaft 23 passes through the bushing 24 in a first direction. One end of the rotating shaft 23 is fixedly connected to the mounting plate 3, and the other end is connected to the rotary brake assembly 4 for transmission. It can be understood that, in order to make the rotating shaft 23 rotate more smoothly, a bearing can be installed inside the bushing 24, and the transmission shaft passes through and is fixed inside the bearing.
[0040] In some embodiments, such as Figure 1 and Figure 3 As shown, the fixture for outdoor circuit breakers of this utility model also includes casters 6, which are disposed at the bottom of the base 1. It can be understood that multiple casters 6 can be provided, and multiple casters 6 are arranged around the circumference of the base 1 to realize the movement support and directional adjustment of this fixture.
[0041] The fixture for outdoor circuit breakers disclosed in this utility model adapts to different models of circuit breakers by setting an adjustable first bracket 21 and a second bracket 22 on the base 1. The circuit breaker is flipped by rotating the mounting plate 3 via the rotary braking assembly 4. It can also maintain the rotation angle of the mounting plate 3 and the circuit breaker in real time, without being limited by the spacing of the sockets, greatly simplifying the adjustment method of the circuit breaker rotation angle and providing high adjustment accuracy.
[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
