SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at is exactly to the location structure of above-mentioned current circuit breaker handle, and the demand part is more, and the great technical defect of occupation space provides a circuit breaker handle rotational positioning structure, under the condition that reduces the part, can reach the function of location equally, and the required space that occupies is reasonable, has practiced thrift the cost.

Technical scheme

In order to realize above-mentioned technical purpose, the utility model provides a pair of circuit breaker handle rotational positioning structure, including handle and base, the handle includes handle and pivot, the pivot is installed mounting groove on the base is downthehole, its characterized in that: the wall of the installation groove hole is provided with an elastic arm, the elastic arm is provided with a boss, and a boss sliding avoidance groove and a boss positioning groove corresponding to the boss are arranged on the shaft surface of the rotating shaft corresponding to the wall of the installation groove hole.

Furthermore, when the boss is positioned in the boss sliding avoiding groove and the boss positioning groove in the rotating process of the rotating shaft, the elastic arm does not deform;

when the boss leaves the boss sliding avoidance groove and the boss positioning groove in the rotating process of the rotating shaft, the elastic arm deforms. The structure effectively reduces the deformation holding time and improves the durability of the elastic arm.

Preferably, the handle of the handle adopts a honeycomb structure, and honeycomb holes of the honeycomb structure are hexagonal.

Advantageous effects

The utility model provides a pair of circuit breaker handle rotational positioning structure through having set up an elastic arm on the base, sets up the boss on the elastic arm, sets up in the pivot and slides and keep away the position groove, through reducing deformation hold time, improves the durability of elastic arm, increase of service life, whole location structure is under the condition that reduces the part, can reach the function of location equally, and the required space that occupies is reasonable, has practiced thrift the cost.
