Each base has an operating component on its surface. The operating component comprises a main body and a beak-shaped closing / opening component. The side of the closing / opening component away from its tip is rotatably connected to the main body. An elastic element is located inside the main body, and the side of the closing / opening component away from its tip is connected to the interior of the main body via this elastic element. This handle operator changes the contact point with the miniature circuit breaker handle from a rigid structure to an elastic structure, effectively absorbing mechanical shock and vibration. Through the elastic design, it better conforms to the movement trajectory of the miniature circuit breaker handle during closing and opening, effectively solving the problem of jamming during operation and making the operation gentler, thus reducing the risk of damage to the miniature circuit breaker handle.

Description

Technical Field

[0001] This utility model relates to the field of miniature circuit breaker technology, and in particular to a handle operator. Background Technology

[0002] Miniature handle operators are primarily used to control the opening and closing of miniature circuit breakers. According to GB / T10963.1-2020, miniature circuit breakers need to undergo 4000 opening and closing operations. According to standards such as GB / T 31143, GB / Z 40680, and GB / T16917 series, operational characteristic tests, such as fault arc operating characteristics and residual current operating characteristics, require multiple opening and closing operations of samples under full voltage conditions. Considering the requirements for testing safety and efficiency, a miniature handle operator was specifically designed. Figure 1 As shown, the miniature handle operator is pushed up and down by an external force (such as a pneumatic solenoid valve) to control the opening and closing of the miniature circuit breaker handle. Existing miniature handle operators have the following disadvantages: 1. The impact force when the miniature handle operator contacts the miniature circuit breaker handle is relatively large, easily damaging the handle during opening and closing; 2. The miniature circuit breaker handle has a certain curvature during opening and closing operations, while the miniature handle operator moves vertically, which can cause mechanical jamming of the miniature circuit breaker handle.

[0026] refer to Figure 3 , 5 As shown, the surface of the base 2 is provided with multiple connecting grooves 21. In this embodiment, each base 2 is provided with two connecting grooves 21. A guide rail 311 is provided on one side of the main body 31. The connecting grooves 21 and the guide rail 311 are connected to each other to fix the operating component 3 in the horizontal position.

[0027] Bolt holes are provided in the connecting groove 21, and bolt holes are provided in the guide rail 311 at the corresponding positions of the bolt holes in the connecting groove 21. The connecting groove 21 is fixedly connected to the guide rail 311 by bolts.

[0028] The cross-section of the slide rail 1 is an arc shape. The side wall of the connection hole between the base 2 and the slide rail 1 is provided with a slot 22. A clamping member 23 is provided in the slot 22. The clamping member 23 cooperates with the straight edge of the cross-section of the slide rail 1 to fix the base 2 in the horizontal position.

[0029] The inner side of the slot 22 is provided with a through hole that communicates with the outer wall of the base 2. The clamping member 23 is provided with a hole corresponding to the position of the through hole. The locking member 24 is connected to the through hole by a thread. The locking member 24 can be a locking nut. The clamping member 23 is connected to the base 2 through the locking member 24. By locking the locking member 24, the base 2 is fixedly connected to the slide rail 1.

[0030] refer to Figure 4 , 5 As shown, the assembly / disassembly component 32 is connected to the main body 31 via a pin 33, and the assembly / disassembly component 32 can rotate about 10 degrees around the pin 33;

[0031] The main body 31 has a through hole inside, and an elastic element 35 is provided in the through hole. One end of the elastic element 35 is connected to the top cap 34, and the other end is connected to the pre-tightening element 36. The end of the top cap 34 away from the elastic element 35 abuts against the connecting and separating part 32. The inner wall of the through hole of the main body 31 away from the connecting and separating part 32 is provided with threads. The outer side of the pre-tightening element 36 is also provided with threads. The outer side of the pre-tightening element 36 is connected to the main body 31 through threads. The elastic force of the elastic element 35 can be adjusted by turning the pre-tightening element 36.

[0032] refer to Figure 6 , 7 As shown, one end of the top cap 34 is provided with a top cap protrusion 341, one end of the elastic member 35 is sleeved on the top cap protrusion 341, one end of the pre-tightening member 36 is provided with a pre-tightening member protrusion 361, and the other end of the elastic member 35 is sleeved on the pre-tightening member protrusion 361.

[0033] The specific working method is as follows:

[0034] The base 2 drives the operating component 3 to move on the slide rail 1. After the position is determined, the locking piece 24 is tightened to fix its position. The slide rail 1 moves up and down with a fixed stroke under the push of the pneumatic solenoid valve (not specified here). The closing / opening component 32 is connected to the main body 31 through the pin 33 and can rotate around the pin 33. Because it is restricted by the main body 31, it can rotate about 10 degrees. Under the action of the elastic member 35, the closing / opening component 32 is held in a certain position. When the handle operator moves upward, the closing / opening component 32 pushes the miniature circuit breaker handle to close. At this time, the reaction force generated by the miniature circuit breaker handle causes the closing / opening component 32 to rotate. When the reaction force generated by the miniature circuit breaker handle disappears, the closing / opening component 32 returns to its original position. The opening principle of the miniature circuit breaker handle is the same as that of the closing principle. If different elastic forces are required, they can be adjusted by tightening the preload 36.

[0035] The beneficial effects are:

[0036] This utility model discloses a handle operator, in which the contact point with the miniature circuit breaker handle is changed from a rigid structure to an elastic structure, which can effectively absorb mechanical shock and vibration. Through the elastic design, it more closely follows the movement trajectory of the miniature circuit breaker handle during the closing and opening process, effectively solving the problem of jamming during the closing and opening of the miniature circuit breaker handle, making the closing and opening of the miniature circuit breaker more gentle, and reducing the risk of damage to the miniature circuit breaker handle.
