Embodiment Construction
[0028] The following is attached Figure 1 to 6 The given examples further illustrate the specific implementation of the drawer cabinet interlocking operating mechanism of the circuit breaker created by the present invention. The drawer cabinet interlocking operating mechanism of the circuit breaker created by the present invention is not limited to the description of the following embodiments.
[0029] Such as figure 1 with figure 2 As shown, the drawer cabinet interlocking operating mechanism of the circuit breaker created by the present invention includes a sleeve gear 10, a positioning gear 20, a locking member 30, a driving rocker 40 and a transmission rod 50. The shaft sleeve gear 10 is connected to the drawer cabinet through the transmission rod 50 The positioning gear 20 includes a gear body 21 and a first limit block 22. The first limit block 22 is located on the surface of the gear body 21. The gear body 21 meshes with the sleeve gear 10 for transmission; the outer sid...

A circuit breaker drawer cabinet interlocking operation mechanism comprises a shaft sleeve gear, a positioning gear, a locking part, a driving rocker arm and a driving rod. The shaft sleeve gear is connected with a drawer cabinet through a transmission rod, the positioning gear comprises a gear body and a first limit block positioned on the surface of the gear body, the gear body is engaged with the shaft sleeve gear each other, one end of the locking part is abutted to the outer edge of the first limit block, the other end of the locking part is embedded into a clamping groove of the drivingrocker arm when one end of the locking part is abutted to the projecting edge of the first limit block, and the other end of the locking part is moved out from the clamping groove of the driving rocker arm when one end of the locking part is abutted to the recessed edge of the first limit block. According to the circuit breaker drawer cabinet interlocking operation mechanism, the different connecting states of the locking part, the positioning gear and the driving rocker arm are converted under different stroke states of the drawer cabinet, opening and closing states of the drawer cabinet under the special stroke states are further locked, and the use reliability of the circuit breaker drawer cabinet interlocking operation mechanism is improved.
Description
Technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a drawer cabinet interlocking operating mechanism of a circuit breaker. Background technique [0002] The withdrawable circuit breaker is a circuit breaker that can disconnect the power supply. The circuit breaker body is placed in the drawer cabinet, and the circuit breaker isolation is realized by swinging in and out of the drawer base. At present, the drawer cabinet operating mechanism used on the circuit breaker has high requirements for the corresponding relationship between the transmission mechanism and the stroke. Most of the existing drawer cabinet operating mechanisms are manually adjusted and determined through the operator’s experience, even if a small number of drawers appear The cabinet operating mechanism can be locked when the drawer cabinet is in a certain stroke state (such as connection, test, separation), but there is no further lock for the opening a...
