Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electrical appliances, in particular to a quick tripping mechanism device. Background Technique

[0002] The quick opening technology is very effective in scenarios such as overvoltage. When the detection line device detects overvoltage, the small electric operating mechanism will perform the opening operation. The faster the opening speed, the more effectively it can protect the line at the load end.

[0003] The prior art generally uses an electronic release for tripping, which has a high cost. Due to the magnetic protection coil structure, it cannot be switched for a long time, and it occupies a large space, which is not conducive to movement in the case of low cost and small space. At the same time, the prior art also uses a cam structure, and the tripping rod is driven by the cam to achieve opening. However, in this scheme, once gear skipping or installation error occurs, the device will misjudge. Therefore, we propose a quick tripping mechanism device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a quick tripping mechanism device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

The braking handle and the clutch gear are coaxially connected and the clutch gear is located inside the braking handle. One end of the connecting rod is connected to the tripping piece, and the other end of the connecting rod is connected to the clutch gear. The tripping pin is located at the lower end of the tripping piece.

[0007] Preferably, a connecting rod hole is provided on the outer surface of the middle part of the tripping piece. A baffle is integrally formed on the outer surface of the tripping piece. A tripping shaft hole for cooperating with the tripping pin is provided at the lower end of the tripping piece. A tripping linkage groove is provided at the upper end of the tripping piece.

[0008] Preferably, one end of the connecting rod is provided with a connecting rod end, and the other end of the connecting rod away from the connecting rod end is provided with a connecting rod top.

[0009] Preferably, a clutch groove hole is provided at the upper end of the clutch gear, and the clutch groove hole is an arc structure.

[0010] Preferably, a groove hole top is provided on one side of the clutch gear, and a groove hole end is provided on the side of the clutch gear away from the groove hole top.

[0011] Preferably, the end of the connecting rod is inserted into the connecting rod hole on the release fastener, and the top of the connecting rod is inserted into the end of the slot hole on the clutch slot hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is mainly used for the quick release of a miniature circuit breaker. This structure has a small movement angle and fast release, achieving a real quick trip. Moreover, the cost is extremely low and the assembly is simple. Since it is an end movement, the overall structure is relatively stable and reliable.

[0014] 2. The utility model realizes quick release through the feature groove on the gear, the release lever and the intermediate metal connecting rod.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] A quick release mechanism device, including a release part 1, a brake handle 2, a release pin 3, a connecting rod 4 and a clutch gear 5. The brake handle 2 and the clutch gear 5 are coaxially connected and the clutch gear 5 is located inside the brake handle 2. One end of the connecting rod 4 is connected to the release part 1, and the other end of the connecting rod 4 is connected to the clutch gear 5. The release pin 3 is located at the lower end of the release part 1.

[0025] In this embodiment, a connecting rod hole 11 is provided on the outer surface of the middle part of the release part 1. A baffle 13 is integrally formed on the outer surface of the release part 1. A release shaft hole 12 for cooperating with the release pin 3 is provided at the lower end of the release part 1. A release linkage groove 14 is provided at the upper end of the release part 1. One end of the connecting rod 4 is provided with a connecting rod end 41, and the end of the connecting rod 4 far from the connecting rod end 41 is provided with a connecting rod top 42. A clutch groove hole 51 is provided at the upper end of the clutch gear 5, and the clutch groove hole 51 is an arc-shaped structure. A groove hole top 511 is provided on one side of the clutch gear 5, and a groove hole end 512 is provided on the side of the clutch gear 5 far from the groove hole top 511. The connecting rod end 41 on the connecting rod 4 is inserted into the connecting rod hole 11 on the release part 1, and the connecting rod top 42 on the connecting rod 4 is inserted into the groove hole end 512 on the clutch groove hole 51.

[0026] It should be noted that the present utility model is a quick release mechanism device. During use, in the normal closing position: in this state, all components are in the initial position. The braking handle 2 and the clutch gear 5 are both in the closing position. The connecting rod 4 is connected to the release member 1 through the connecting rod hole 11, and the release pin 3 is located in the release shaft hole 12, ready; when electrically tripping: in the electric operation mode, the clutch gear 5 is instantaneously started and rotates rapidly clockwise. The end 512 of its slot contacts the top end 42 of the connecting rod, driving the whole connecting rod 4 to rotate clockwise. The end 41 of the connecting rod is engaged with the connecting rod hole 11 on the release member 1, prompting the release member 1 to rotate in the same direction. At this time, the release pin 3 moves upward along the direction of the release shaft hole 12 and strikes the release mechanism inside the miniature circuit breaker to achieve quick tripping; when electrically closing, the clutch gear 5 rotates counterclockwise, driving the braking handle 2 to return to the closing position. During this process, the top end 42 of the connecting rod on the connecting rod 4 is not affected in the clutch slot 51. At this time, the position of the release pin 3 remains unchanged, preparing for the next tripping.
