Embodiment

?below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, extraction and the insert structure of pull-out type band bypass automatic transfer switching electric appliance described in the utility model, for utilizing the transmission of screw mandrel and rack-and-pinion, the strength of staff actuating rocking bar is changed into the rotational power of casing underframe the inside square shaft, by the plate at square shaft two ends, stir the swing arm of being fixed on box side again, thus the extraction that realizes body by the rotation with the fixing guide plate of swing arm with insert function.

A kind of pull-out type band bypass automatic transfer switching electric appliance, mainly by bypass casing 1 and change over switch body 2, formed, bypass casing 1 and change over switch body 2 are two independent modules, these two modules are integrated in working order time, when product needed is overhauled, just change over switch body can be extracted out and be keeped in repair.On bypass casing 1, be provided with and extract out and insert structure, this structure comprises bypass casing underframe 4, jockey, supporting bracket 9, rocking bar 11, square shaft 12, fixed axis 13, screw component 14, connecting plate 15, rack and pinion assembly 16.Whole bypass casing 1 is fixed on bypass casing underframe 4; Jockey is left and right symmetrical structure, includes switch-plate shaft 5, swing arm 6, fixed head 7, guide plate 8, plate 10; Switch-plate shaft 5 one end are fixed on bypass casing underframe 4, and the other end is connected with swing arm 6; Fixed head 7 is fixed on the side plate of by-pass switch 1; Opposite side swing arm 6 is fixed in the rotating shaft in supporting bracket 9, and swing arm 6 simultaneously is also fixedly connected with guide plate 8.Feed screw nut on screw component 14 is fixedly connected with connecting plate 15, and rack and pinion assembly 16 middle racks are fixed on connecting plate 15, matches with the tooth bar on square shaft 12; Plate 10 is fixed on the both sides of square shaft 12, and change over switch body 2 is provided with bearing 3, for matching with the guide plate 8 on bypass casing 2.

Fig. 5 is that in the utility model, bypass casing is extracted the first schematic diagram with insert structure out; Fig. 6 is that in the utility model, bypass casing is extracted the second schematic diagram with insert structure out; Fig. 7 changes the swing arm of Switch main body when extracting out and the position view of bearing in the utility model; Fig. 8 changes the swing arm of Switch main body when inserting and the position view of bearing in the utility model.

Concrete motion principle is described as follows:

When change over switch body is when extraction state need be inserted in bypass casing 1; the position of change over switch body 2 in bypass casing 1 as shown in Figure 7, is now fixed on the gathering sill outside of the bearing 3 fixing guide plate 8 on bypass casing 1 on change over switch body 2; When shaking clockwise rocking bar 11, rocking bar 11 drives screw component 14 to clockwise rotate, the connecting plate 15 fixing with screw component 14 moved backward, by the rack and pinion assembly 16 being fixed on connecting plate 15, drive the gear on square shaft 12 to do counterclockwise motion, square shaft 12 is and then rotated counterclockwise together.The plate 10 that is fixed on square shaft 12 both sides drives the horizontal swinging arm 6 being fixed in side plate and supporting bracket 9 to do clockwise motion simultaneously, the left and right guide plate 8 being fixed together with swing arm 6 is also done clockwise motion simultaneously, the bearing 3 being fixed on change over switch body 2 is promoted to casing the inside, thereby drive change over switch body 1 to be inserted into stably box house.

When change over switch body 2 is just in time contrary with above-mentioned motion when insertion state need be extracted maintenance out, now only need shake counterclockwise rocking bar 11 just.
