Technical field

The utility model belongs to toy art, and in particular to a kind of to be played with the lint of all kinds of moulding with what gear drove Have one kind for combining to turn a somersault machine core.

Background technique

Emulate class toy toy kind it is more and more, simulated actions type toy be by belt transmission or gear drive, Reach a type toy of certain effects by changing a series of transmission ratios and transmission direction change movement range, cooperation acousto-optic can Show very strong interest, is pursued by the majority of consumers.The existing toy that can be turned a somersault mostly is clockwork spring driving, is continued Property and interest it is of inadequate achievement, also useful motor directly drives swing arm and realizes rotation, but the transmission directly driven with motor The torque that mode is transmitted is smaller, and the service life of complete machine and volume, the weight of machine core are all restricted.

Summary of the invention

The utility model overcomes existing defect to provide one kind to turn a somersault machine core, and the structurally reasonable rotation that can be realized machine core is in It now turns a somersault movement.

Compared to the prior art the utility model has the advantage that

It turns a somersault machine core, including casing, is rotatably connected on the arm of casing two sides and the driving device of casing internal； The lower end of the arm is lower than the bottom of casing, and the driving device includes one group of train of reduction gears being driven by motor, described The output shaft of train of reduction gears is a horizontally disposed square shaft, and two rotating connectors are plugged on the both ends of square shaft respectively, two A protruding casing of rotating connector is connect with two arms respectively, in the extension end and arm upper end of the rotating connector The square hole that side is equipped with is plugged and fixed.

The further improvement project of the utility model is that the middle part of the rotating connector is equipped with a circle annular convex platform, institute It states casing and is equipped with the mounting groove rotated with annular convex platform cooperation.

The further improvement project of the utility model is that the motor and train of reduction gears are mounted in tooth case, motor Shaft stretches out tooth case and extension end is equipped with small belt pulley, and the small belt pulley and the big belt pulley above it are driven by belt Connection, the big belt pulley are mounted on the input shaft of the train of reduction gears.

The further improvement project of the utility model is that the train of reduction gears is the three-level reducing gear being mounted in tooth case Wheel group.

The further improvement project of the utility model is that the arm is the arc that middle part is arched upward outward, the arm Lower end surface in the middle part of be equipped with inverted U-shaped notch.

Compared to the prior art the utility model has the advantage that

The utility model drives train of reduction gears to drive rotating connector to rotate by motor, and then drives two sides It rolls over, drive mechanism advantages of simple transmitting torque is big, is suitable for large volume machine core, the length of arm is longer to be supported on It rotates casing integrally around arm, while can also crouch and be placed on bottom surface, electric motor starting rear arc arm resists ground energy It is enough that entire casing is lifted into the continuous movement of turning a somersault of presentation, more motion actions, true to nature, interest height.

Specific embodiment

Machine core of turning a somersault as shown in Figure 1, 2, 3 including casing 1, is rotatably connected on arm 2, the Yi Jiji of 1 two sides of casing Driving device inside shell 1.The lower end of arm 2 is lower than the bottom of casing 1, and arm can be individually placed on the ground by entire machine Shell supports.Driving device includes one group of train of reduction gears 4 driven by motor 3, and the output shaft of the train of reduction gears 4 is one The horizontally disposed square shaft 5 of root, two rotating connectors 6 are plugged on the both ends of square shaft 5 respectively, and square shaft rotation drives rotating connector Rotation, two protruding casings of rotating connector 6 connects with two arms 2 respectively, the extension end of the rotating connector 6 and The square hole 7 being equipped on the inside of 2 upper end of arm is plugged and fixed, and rotating connector rotates two arms and follows rotation, and two arms are forbidden When motionless, casing is overturn around arm, and playability is high.

In the present embodiment, the middle part of rotating connector 6 is equipped with a circle annular convex platform 8, and the casing 1 is equipped with and the ring The mounting groove of the cooperation rotation of shape boss 8, the casing of the present embodiment are divided into front, back casing, and front and back casing is connected by bolt, front and back Half of mounting groove is respectively opened on casing, forms entire mounting groove after combination is fixed, and the annular convex platform at 6 middle part of rotating connector is stuck in peace It can be rotated in tankage.Motor 3 and train of reduction gears 4 are mounted in tooth case 9, and motor is stretched out in tooth bottom portion, the shaft of motor 3 Tooth case 9 and extension end are equipped with small belt pulley 10, and the small belt pulley 10 is passed with the big belt pulley 11 above it by belt 12 Dynamic connection, big belt pulley 11 are located on the outside of tooth case, and big belt pulley 11 is mounted on the input shaft 13 of train of reduction gears 4.Reducing gear Wheel group 4 is the three-level train of reduction gears being mounted in tooth case 9, i.e. the square shaft 5 in addition to input shaft 13 and output, and there are also two transmissions Axis, and gear is designed on every transmission shaft, engagement reaches slowing effect step by step.Arm 2 is the arc that middle part is arched upward outward, After can falling, arcuate arm, which can resist ground and lift entire casing, continuously turns a somersault.It is equipped in the middle part of the lower end surface of arm 2 U-shaped breach 14 can be stablized and support casing, casing integrated hanging, can rotate around arm.
