DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a debugging tooling for a circuit breaker propulsion mechanism, including a bracket 1. Two guide rails 5 are fixedly connected to the bracket 1. The guide rails 5 are used to guide the movement direction of the test trolley frame 6. The test trolley frame 6 is movably installed between the two guide rails 5. Rolling wheels 19 slidably connected to the guide rails 5 are installed on both sides of the test trolley frame 6. The rolling wheels 19 facilitate the sliding of the test trolley frame 6 on the guide rails 5. Support rods 3 are fixedly connected to both sides of the top of the bracket 1. The top of the support rods 3 is fixedly connected with a bottom plate 8. A slide rail 16 is installed on the top of the bottom plate 8. A slider 9 is slidably connected to the outside of the slide rail 16. By providing the slider 9 and the slide rail 16, the support plate 12 and the limit plate 10 can be slidably adjusted to adapt to circuit breaker propulsion mechanisms of different sizes. The slider 9 is fixedly connected with a support plate 12. A limit plate 10 is integrally formed on the top of the support plate 12. The circuit breaker propulsion mechanism can be installed between the two limit plates 10, and the protrusions at both ends of the circuit breaker propulsion mechanism can be snapped into the U-shaped groove 11, thereby playing a limiting role. Then, by connecting the mobile end of the circuit breaker propulsion mechanism to the test trolley frame 6 with screws, the circuit breaker propulsion mechanism can be debugged without installing it on the switch cabinet for debugging, simplifying the installation steps and reducing the adjustment difficulty. A U-shaped groove 11 is opened in the middle of the limit plate 10.

[0018] Among them, a positioning rod 17 is slidably connected to the support plate 12. The positioning rod 17 and the positioning hole 7 cooperate to fix the slider 9, thereby fixing the limit plate 10 and preventing the circuit breaker propulsion mechanism from moving. A pressing block 14 is rotatably connected to the top of the positioning rod 17. By rotating the pressing block 14, the pressing block 14 can drive the positioning rod 17 to move in the vertical direction, so that the positioning rod 17 enters or exits the positioning hole 7. An arc surface 15 is provided on one side of the pressing block 14. The arc surface 15 facilitates the rotation of the pressing block 14 and avoids the pressing block 14 being stuck by the support plate 12 and unable to rotate. A grip 13 is provided on the other side of the pressing block 14. The grip 13 facilitates the user to rotate the pressing block 14. Multiple positioning holes 7 cooperating with the positioning rod 17 are provided on the top of the bottom plate 8.

[0019] Among them, a contraction part 18 is provided at the bottom of the positioning rod 17. The contraction part 18 facilitates the alignment of the positioning rod 17 and insertion into the positioning hole 7.

[0020] Among them, a storage box 4 is fixedly connected to the top of the bracket 1. The storage box 4 is used to place parts or tools to avoid loss.

[0021] Among them, universal wheels 2 are installed at the bottom of the bracket 1. The universal wheels 2 facilitate the movement of the bracket 1.

[0022] Specifically, during debugging, the grip 13 is pulled upwards, causing the pressing block 14 to rotate with the connection point with the positioning rod 17 as the center of the circle. The arc surface 15 of the pressing block 14 contacts the support plate 12, and the pressing block 14 drives the positioning rod 17 to move upwards until the pressing block 14 rotates to a vertical state. At this time, the positioning rod 17 disengages from the positioning hole 7, and then the slider 9 can slide. Adjust the appropriate position of the limit plate 10 according to the length of the circuit breaker propulsion mechanism. After the adjustment is completed, pull the grip 13 downwards until the pressing block 14 rotates to a horizontal state. At this time, the positioning rod 17 snaps into the positioning hole 7, making the limit plate 10 unable to move. Then, place the circuit breaker propulsion mechanism between the two limit plates 10, and the protrusions at both ends of the circuit breaker propulsion mechanism snap into the U-shaped groove 11 to fix the circuit breaker propulsion mechanism. Finally, connect the mobile end of the circuit breaker propulsion mechanism to the test trolley frame 6 through bolts to debug the circuit breaker propulsion mechanism.
