The planetary drive wheel includes two gears, one with revolution axis connection, another and rotation axis connection, revolution Gear on axis is engaged with planet carrier.

The shell is equipped with concave station, and the bulge loop as planet carrier is located on concave station.

Safety head is equipped with outside the rotary table, the safety head is snapped connection with shell, and the safety head is Transparent.

Compared with the prior art, the utility model has the following advantages: increasing by two mutual cooperation turntables, two turntables are logical The rotation relation cooperatively formed between simulated solar and the earth is crossed, to the section of user's especially pupil's science popularization rotation and revolution It gains knowledge, makes full use of penknife self structure and feature, not needing to do big adjustment to penknife structure itself can be real Existing, at low cost and interest is strong, is particularly suitable for pupil and uses, does not increase the buying expenses of parent also.

Specific embodiment

As shown in figures 1 to 6, the utility model penknife, it includes shell 1, is equipped in shell 1 for installing bite core From into bracket 2, for driving the handle 4 from into the main turntable 3 of bracket 2 and for driving bite core, it is also wrapped Include rotary table 5 and autorotation disk 6, rotary table 5 is equipped with hollow shaft 7, and autorotation disk 6 also is provided with the axis of rotation 8, hollow shaft 7 and the axis of rotation 8 it Between be cooperatively connected through planetary drive wheel 11 and planetary drive wheel 11 is located at below autorotation disk 6, the back side of the main turntable 3 is equipped with Multiple pillars 9 as moving tooth, the pillar 9 are circumferentially uniformly distributed along main turntable 3, are additionally provided with below the axis of rotation 8 Transmission gear 10, the transmission gear 10 are engaged with the pillar 9 on main turntable 3, and 1 upper surface of shell is equipped with bulge loop 12, the inner wall setting rack gear of bulge loop 12 makes bulge loop 12 play the role of planet carrier, and the planetary drive wheel 11 is located at bulge loop 12 Interior and engage with the rack gear of 12 inner wall of bulge loop, rotary table 5 connect and is located at the upper surface of autorotation disk 6 with the upper end of hollow shaft 7, public The lower end of shaft 7 is connect with planetary drive wheel 11.Above structure is available under the drive of main turntable 3, passes through transmission gear 10 Planetary drive wheel 11 is driven to move, autorotation disk keeps original place rotation, and rotary table is rotated around the axis of rotation, realizes simulated solar and ground Movement relation between ball has good science popularization meaning.Planet carrier on shell is played to 11 stabilization of planetary drive wheel, Guarantee that autorotation disk and rotary table being capable of smooth rotations.

Specifically, the planetary drive wheel 11 includes two gears, one connect with hollow shaft 7, another and rotation Axis 8 connects, and the gear on hollow shaft 7 is engaged with planet carrier.This is the concrete mode of planetary drive wheel 11 in the present embodiment, planet Driving wheel 11 is more mature, is not repeated.

The shell 1 is equipped with concave station, and the bulge loop 12 as planet carrier is located on concave station.Outside penknife Globality is more preferable, is also convenient for collecting, and the turntable of simulated solar and the earth is accommodated with concave station, is not take up exceptional space, storage When be also not easy to collide with, avoid being easily damaged.

It is that safety head is equipped with outside the rotary table 5 that further improvement, which is employed all means available, and the safety head and shell 1 block Button connection, the safety head are transparent.Safety head plays protection and isolation to turntable, so that entire rotational structure is more It the use of transparency cover is even more under the premise that security is guaranteed, moreover it is possible to guarantee observing effect, not need to remove safety head for safety and stability The rotation relation of autorotation disk and rotary table can be observed.
