And lock) and exit and (exited testing position by operating position and locked) function, vacuum is generally carried using a chassis vehicle
Breaker is taken turns by the driving being equipped on the chassis vehicle and moves ahead or retreat on the track in switchgear.Existing electric chassis
Vehicle includes end carriage, screw rod, motor, handle, car body and control system, by swinging handle or is driven by motor so that silk when work
Bar drives vehicle frame and the breaker on vehicle frame to move to operating position or exit.It can band when motor works in real work
Dynamic screw rod rotation, if being sheathed on handle on screw rod at this time, motor will drive handle rotation, and handle may fly to throw away because of centrifugation
Or staff is driven to roll over, there are some potential safety problems, and the circuit breaker chassis energy of manual priority function
So that when being inserted into handle, motor is failure to actuate, so that the above motor be avoided to turn by arm of the lead screw with fixed handle and staff
It is dynamic, however such structure still has some potential safety problems, due in manual operation, the chassis vehicle of manual priority due to
Reasons in structure will receive thrust reversed when handle insertion, so that handle in rotation, is easy to fall off with lead screw, influence chassis vehicle
Manual operation performance.

Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown in Fig. 1 combination Fig. 2-4, a kind of circuit breaker chassis with manual priority function, including end carriage 1, transmission
Bar 2 and car body 3, one end of the drive rod 2 are set on car body 3, and the other end passes through car body 3 and is set on end carriage 1 and is used for and hand
Handle is adapted, and the drive rod 2 is equipped with the first mounting hole 21, is equipped with 22 He of the first card bead in first mounting hole 21
Second card bead 23, first card bead 22, the second card bead 23 are protruded outside drive rod 2 respectively for matching with handle inner wall.
The utility model has the beneficial effects that being provided with two card beads, can be mutually clamped with the inner wall of handle, thus not influencing handle
While with drive rod rotation, so that having biggish resistance between handle and drive rod, and the drag direction and drive rod are axial
It is parallel, avoid handle from falling off without the normal rotation for influencing drive rod.The utility model also has structure simple, assembly side
