The specific embodiment
Referring to figs. 1 through Fig. 7; Present embodiment is a kind of toy fire fighting truck that uses toy aerial ladder synchronization lifting telescoping mechanism; Be at the toy fire fighting truck aerial ladder synchronization lifting telescoping mechanism to be set, aerial ladder synchronization lifting telescoping mechanism comprises the shared gear train of a motor 1, a group 2, one group of expansion teeth wheels 3 and one group of lifting tooth wheels 4; The gear of each gear train is located in the tooth case 5 through pedestal separately, and the tooth case is installed on the toy through tooth block 6; The input of motor connects power switch, and the output of motor connects the gear wheel 7 of shared gear train; Shared gear train comprises gear wheel 7 and change- speed gearing 8,9,10, and gear wheel drives transmission chain wheel 11 after the change-speed gearing speed change of shared gear train; The expansion teeth wheels comprise rear end change- speed gearing 12,13, connecting shaft imperial crown tooth 14,15 and front end travelling gear 16; Its rear end change-speed gearing 12 is by the chain wheel transmission; Tooth bar 18 engaged transmission of the interior aerial ladder 17 of its front end travelling gear and toy constitute toy aerial ladder telescoping mechanism; The lifting tooth wheels comprise by the tooth 20 of chain wheel Synchronous Transmission with by the sector gear 21 of tooth 20 transmissions, and the interior aerial ladder support of itself and toy connects during by the sector gear rotary oscillation, constitutes the elevating mechanism of toy aerial ladder; Be provided with the flexible protection mechanism of protection tooth 22, spring 23, copper cup scholar 24 formations between the front end travelling gear 16 of expansion teeth wheels and the imperial crown tooth 15; Be provided with the up-down protection mechanism of protection tooth 25, spring 26, copper cup scholar 19 formations between the tooth 20 of lifting tooth wheels and the chain wheel 11.
The assembling process of the utility model: design the link of expansion teeth wheels 3, shared gear train 2, lifting tooth wheels 4 earlier, design the link of expansion teeth wheels and interior aerial ladder 17 again; Fix the circular hole of the corresponding gear wheel 7 of an end of motor 1; Be contained in the top of motor to shared gear train again and mesh with gear wheel; Be assembled in lifter wheel rear side and its engagement of shared gear train; Expansion teeth wheel be assembled in shared gear train front side and with its engagement, be contained in expansion teeth wheels top to interior aerial ladder and make its tooth bar 18 and the engagement of expansion teeth wheels, thus composition aerial ladder synchronization lifting telescoping mechanism.Pack into the assigned address of tooth case 5 of aerial ladder synchronization lifting telescoping mechanism is fixed, fixing on the aerial ladder 17 in outer aerial ladder is contained in; Whole tooth case is contained on the tooth block 6 again and fixes, the assigned address that is installed in the tooth block toy fire fighting truck vehicle body gets final product.
The use principle of the utility model: because shared gear train connects lifting tooth wheels and expansion teeth wheels simultaneously, therefore up-down and expanding-contracting action carry out synchronously.The action of going up and down is to drive the tooth case through lifter wheel to rotate, and is provided with protection mechanism, promptly in the rotation process, has external force to stop normal rotation, does not also damage parts.Flexible action is the tooth bar engagement through flexible gear and interior aerial ladder, reaches the flexible effect of aerial ladder, and is provided with protection mechanism, promptly in the aerial ladder telescopic process, has external force to stop normal expanding-contracting action, does not also damage parts.
The use of the utility model: when the control bar of manual control box is up pressed, the motor energising, the motor gear wheel rotates, thereby drives shared gear train, and then drives lifting tooth wheels and expansion teeth wheels, and the aerial ladder of fire fighting truck begins rise and stretches out; When the control bar of manual control box is down pressed, the motor counter-rotation, thus drive shared gear train, and then driving lifting tooth wheels and expansion teeth wheels, the aerial ladder of toy fire fighting truck begins landing and contraction; Owing to going up and down and stretching protection mechanism is arranged all; When running into undesired use, except playing a protective role,, aerial ladder hinders when running into external force; Make when the corner that goes up and down is asynchronous with flexible distance; As long as the circulation primary operation can be got back to the corner of aerial ladder and the synchronous state that stretches, reach reset function.
