In a preferred embodiment of the present invention, described U-shaped plate is fixed on described backing plate by cross recess pan bolt and spring washer and plain washer.
Of the present invention is a kind of protective device with automatic reclosing function, and the present invention reduces the manufacturing cost of product under the prerequisite not affecting properties of product; Metal insert strengthens the stress-bearing capability of gear wheel and connecting rod contact site; Nylon material adds large and small gear, bar cover and connecting rod that glass or polyphenylene sulfide or polytetrafluoroethylene make and coordinates and not easy to wearly when running have insulating properties, self lubricity and high-wearing feature, and bar cover serves the effect of pad; Load unilateral bearing in large and small gear, make it when manual misoperation, large and small gear is all failure to actuate, and only, hexagonal rotating shaft is dallied in the unilateral bearing of pinion.
Accompanying drawing explanation
Fig. 1 is a kind of explosive view had in protective device one preferred embodiment of automatic reclosing function of the present invention;
Fig. 2 is a kind of structural representation had in another preferred embodiment of protective device of automatic reclosing function of the present invention.
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Of the present invention is a kind of protective device with automatic reclosing function, as shown in Figure 1 with Figure 2, comprises middle cover 1, lever 2, handle 3, connecting rod 4, gear wheel 5, motor 6, pinion 7, interior hexagonal rotating shaft 8.
Described handle 3 riveted joint is arranged on described lever 2.
Described motor 6 is arranged on described lever 2 side, and be arranged on the motor shaft of motor 6 by unilateral bearing 9 in the middle of described gear wheel 5, described gear wheel 5 is reliably located by circlip for shaft 10 by described motor shaft top.
Protrusion side, described gear wheel 5 top is provided with metal insert 11.
Described connecting rod 4 two ends are connected with described handle 3 and described metal insert 11 respectively.
Described handle 3 is adopted countersunk head screw 12 with described connecting rod 4 and is connected by bar cover 13.
Described metal insert 11 is fixedly connected with by circlip 10 with described connecting rod 4.
Described pinion 7 to be arranged in described interior hexagonal rotating shaft 8 and with the external toothing of described gear wheel 5.
Backing plate 14 is provided with bottom described interior hexagonal rotating shaft 8.
Described interior hexagonal rotating shaft 8 is also located by U-shaped plate 15.
