Described in the utility model is a kind of protective device with automatic reclosing function, and the utility model reduces the manufacturing cost of product under the prerequisite not affecting properties of product; The large nylon material that is with pinion adds glass or polyphenylene sulfide or polytetrafluoroethylene and makes, and have self-lubricating function, toughness is strong, high temperature resistant, and resistance to wear is by force, not easy to wear in operation process, stable movement; The manual splitting or integrating lock of protective device, with in inner hexagon spanner counterclockwise switching during hexagonal rotating shaft, pinion drives gear wheel running, realizes product splitting or integrating lock; If hexagonal rotating shaft in the switching of inner hexagon spanner clockwise direction, because pinion is built with unilateral bearing, within institute, hexagonal rotating shaft can only be dallied in unilateral bearing, any misoperation will be caused to affect on product; Assemble simple and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of front section view had in protective device one preferred embodiment of automatic reclosing function of the utility model;
Fig. 2 is a kind of vertical view had in another preferred embodiment of protective device of automatic reclosing function of the utility model.
Embodiment
Below preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
Described in the utility model is a kind of protective device with automatic reclosing function, as shown in Figure 1 with Figure 2, comprises gear wheel 1, pinion 2, motor 3, interior hexagonal rotating shaft 4 and fixed housing 5.
Described motor 3 is arranged in the installing hole 6 in described fixed housing 5.
Described gear wheel 1 is nested with on described motor 3.
The side of the motor 3 of described fixed housing 5 is provided with U-shaped plate 7.
Described pinion 2 is nested with in described interior hexagonal rotating shaft 4.
Described interior hexagonal rotating shaft 4 is located by connecting by described U-shaped plate 7.
Backing plate 8 is provided with bottom described U-shaped plate 7 and between fixed housing 5.
Described gear wheel 1 is arranged with the external toothing of described pinion 2.
Also closely cooperated in described gear wheel 1 unilateral bearing 9 being fixedly connected with described motor 3, and the unilateral bearing 9 that closely cooperated equally in described pinion 2 is connected with described interior hexagonal rotating shaft 4.
Together load motor 3 after unilateral bearing 9 and gear wheel 1 tight fit, after unilateral bearing 9 and pinion 2 tight fit, together load interior hexagonal rotating shaft 4.
When protective device energising runs, motor 3 drives unilateral bearing 9 and gear wheel 1 together to operate clockwise, drives pinion 2 to operate by gear wheel 1 simultaneously; The manual splitting or integrating lock of protective device, with in inner hexagon spanner counterclockwise switching during hexagonal rotating shaft 4, pinion 2 drives gear wheel 1 to operate, and realizes product splitting or integrating lock; If hexagonal rotating shaft 4 in the switching of inner hexagon spanner clockwise direction, because pinion 2 is built with unilateral bearing 9, within institute, hexagonal rotating shaft 4 can only be dallied in unilateral bearing 9.
