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; 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 utility model;
Fig. 2 is a kind of structural representation 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 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.
Described U-shaped plate 15 is fixed on described backing plate 14 by cross recess pan bolt 16 and spring washer 17 and plain washer 18.
The protective device with automatic reclosing function comprises gear wheel, connecting rod, inserts, bar cover, unilateral bearing, motor, handle, lever, middle cover, countersunk head screw, circlip for shaft, pinion, backing plate, U-shaped plate, interior hexagonal rotating shaft, Cross Recess Head Screw, when the energising of this protective device runs, driven by motor gear wheel and unilateral bearing run clockwise, the large gear turn the small gear and unilateral bearing and interior hexagonal axis of rotation, pinion and unilateral bearing and interior hexagonal rotating shaft by U-shaped plate and backing plate Cross Recess Head Screw fixing after reliable location, because gear wheel is working of plastics, its working position contacted with connecting rod is stressed larger, easy fracture, therefore employing metal insert, strengthen its stress-bearing capability, and connecting rod and handle contact position, born by bar cover, not only reduce friction of motion, also serve insulating effect, strengthen personal safety, lever and handle adopt rivets, and effectively reduces labour cost and fee of material, when manual conjunction and separating brake, in order to prevent misoperation, loading unilateral bearing in pinion and locking, gear wheel can be driven to carry out closing and separating brake when making it operate counterclockwise, otherwise interior hexagonal rotating shaft is dallied in unilateral bearing.
