Description

Toy excavator

Technical field

The utility model relates to a kind of toy for children imitating engineering machinery, is a kind of toy excavator specifically.

Background technology

Excavator is used for excavating soil and sandstone in engineer operation, has larger attraction to children.Ordinary excavator complex structure, bulky, operation is more complicated, just can need operate through professional training, can not as toy for children, and the excavator cost of integral miniaturization is high, operation is still complicated, is also not suitable for popularizing.

Summary of the invention

The purpose of this utility model is to provide the toy excavator that a kind of structure is simple, easy to operate, cheap, can imitate excavation action.

In order to reach above object, the technical scheme that the utility model adopts is: this toy excavator comprises the armed lever assembly be made up of lifting arm and digging arm, the dipper stick being connected to armed lever assembly front end, is arranged on the scraper bowl of dipper stick lower end, the front end of described lifting arm is hinged on the lower end of dipper stick, and the front end of described digging arm is hinged on the upper end of dipper stick, horizontal steering shaft is separately had to be fixedly mounted on the upper end of base, on described horizontal steering shaft, slip cap is equipped with slip ring, the outer ring surface of described slip ring is fixedly connected with cradling piece and axle bed, the upper end fixed installation seat of described cradling piece, described axle bed is fixedly connected with horizontally disposed axostylus axostyle, on described axostylus axostyle, slip cap is equipped with lifting arm sliding sleeve and digging arm sliding sleeve, described lifting arm sliding sleeve is fixedly connected on the rear end of lifting arm and the lower end of lifting arm control stick, described digging arm sliding sleeve is fixedly connected on the lower end of digging arm control stick, the rear end of described digging arm is hinged on the stage casing of digging arm control stick.

The beneficial effects of the utility model are: this toy excavator structure is simple, easy to operate, cheap, can imitate excavation action, uses as toy.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the plan structure schematic diagram of horizontal steering shaft and base portion.

Detailed description of the invention

As shown in Figure 1 and Figure 2, this toy excavator comprises the armed lever assembly be made up of lifting arm 1 and digging arm 2, the dipper stick 3 being connected to armed lever assembly front end, is arranged on the scraper bowl 4 of dipper stick 3 lower end, the front end of described lifting arm 1 is hinged on the lower end of dipper stick 3, and the front end of described digging arm 2 is hinged on the upper end of dipper stick 3; Separately have horizontal steering shaft 5 to be fixedly mounted on the upper end of base 6, on described horizontal steering shaft 5, slip cap is equipped with slip ring 7, and slip ring 7 is horizontally disposed with and can rotates around horizontal steering shaft 5; The outer ring surface of described slip ring 7 is fixedly connected with cradling piece 8 and axle bed 9, the upper end fixed installation seat 10 of described cradling piece 8, described axle bed 9 is fixedly connected with horizontally disposed axostylus axostyle 11, on described axostylus axostyle 11, slip cap is equipped with lifting arm sliding sleeve 12 and digging arm sliding sleeve 13, and lifting arm sliding sleeve 12 and digging arm sliding sleeve 13 all can rotate around axostylus axostyle 11; Described lifting arm sliding sleeve 12 is fixedly connected on the rear end of lifting arm 1 and the lower end of lifting arm control stick 14, and described digging arm sliding sleeve 13 is fixedly connected on the lower end of digging arm control stick 15, and the rear end of described digging arm 2 is hinged on the stage casing of digging arm control stick 15.

During operation, children are sitting on seat 10, and two hands hold the upper end of lifting arm control stick 14 and digging arm control stick 15 respectively, and twisting health makes seat 10 rotation that slip ring 7 and axle bed 9 can be driven to rotate, thus moves in the scope of operation by the scraper bowl 4 of armed lever assembly front end; Forward and backward promotion lifting arm control stick 14, can change the bowing of lifting arm 1, elevation angle degree, changes the height of scraper bowl 4, realizes scraper bowl 4 and decline or lifting operation; Forward and backward promotion digging arm control stick 15 can be pushed away by digging arm 2, the upper end of draw bucket connecting rod 3, makes the scraper bowl 4 of draw bucket connecting rod 3 lower end realize excavating action.
