Detailed Description

The utility model will be further described in detail with reference to the following examples, which are given in the accompanying drawings.

Referring to fig. 1 to 4, the linear driving structure of the withdrawable circuit-breaker of the present embodiment includes: drawer seat 1 and switching pole 2, actuating lever 3, the drive hole 11 of setting on drawer seat 1, actuating lever 3 and the coaxial setting of drive hole 11, the equal rotatable setting of actuating lever 3, switching pole 2 is in drawer seat 1, actuating lever 3 is connected with switching pole 2 is perpendicular, be equipped with switching gear 21 on the switching pole 2, be equipped with drive assembly 4 on the drawer seat 1, drive assembly 4 connects switching gear 21 and circuit breaker.

Through the technical scheme, when the state of circuit breaker needs to be switched, insert in the drive hole 11 with the handle, make handle and actuating lever 3 accomplish the joint, later twist grip, but the rotatory actuating lever 3 that can rotate, 3 rotatory drive of actuating lever lack the rotation of goods pole, it is rotatory that 2 rotations of switching lever drive switching gear 21, thereby switching gear 21 is rotatory to drive transmission assembly 4 motion, thereby transmission assembly 4 motion switches over the state of circuit breaker, through switching gear 21 drive transmission assembly 4 behind the twist grip, required power is more linear in the driving process, high durability and convenient use.

As a modified specific embodiment, the transmission assembly 4 comprises a transmission gear 41 and a driving gear 42 which are integrally and coaxially arranged, and a driven gear 43 and a pushing gear 44 which are integrally and coaxially arranged, wherein the transmission gear 41 is meshed with the switching gear 21, the driving gear 42 is meshed with the driven gear 43, the pushing gear 44 is connected with the circuit breaker, the diameter of the switching gear 21 is smaller than that of the transmission gear 41, the diameter of the transmission gear 41 is larger than that of the driving gear 42, the diameter of the driving gear 42 is smaller than that of the driven gear 43, and the diameter of the driven gear 43 is larger than that of the pushing gear 44.

Through the technical scheme, when the switching gear 21 rotates, the transmission gear 41 is driven to rotate, the transmission gear 41 rotates to drive the driving gear 42 coaxial with the transmission gear to rotate, the driving gear 42 rotates to drive the driven gear 43 to rotate, the driven gear 43 rotates to drive the pushing gear 44 coaxial with the driven gear to rotate, the pushing gear 44 pushes the circuit breaker to switch states, and the rotating speed on the pushing gear 44 is lower than that on the switching gear 21 because the diameter of the switching gear 21 is smaller than that of the transmission gear 41, the diameter of the transmission gear 41 is larger than that of the driving gear 42, the diameter of the driving gear 42 is smaller than that of the driven gear 43, and the diameter of the driven gear 43 is larger than that of the pushing gear 44, so that the required force in the driving process is more linear, the use is convenient, and the accuracy is improved.
