In the figure: 1-box body, 2-pull rod, 3-handle, 4-groove, 5-universal wheel, 6-roller, 7-small bearing, 8-big bearing, 9-connecting rod, 10-rotating rod, 11-socket and 12-pin shaft.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a household draw-bar box of a planet wheel stair climbing mechanism comprises a box body 1, a draw bar 2 is slidably connected to the left side of the top of the box body 1, a handle 3 is fixedly connected to the top of the draw bar 2, the handle 3 is provided with an anti-slip design, a groove 4 is formed in the left side of the bottom of the box body 1, the size of the groove 4 is larger than that of a structure formed by a connecting rod 9 and a roller 6, a large bearing 8 is fixedly connected to the inner side of the groove 4, a connecting rod 9 is fixedly connected to the outer side of the large bearing 8, the connecting rod 9 is distributed on the large bearing 8 in a surrounding manner, the included angle is one hundred twenty degrees, a socket 11 is formed in one side of the connecting rod 9 away from the large bearing 8, a pin shaft 12 is fixedly connected to one side of the connecting rod 9, the small bearing 7 is, and the height of the structure formed by the connecting rod 9 and the roller 6 is slightly higher than the height of a normal step, the right side of the bottom of the box body 1 is fixedly connected with a rotating rod 10, and the bottom of the rotating rod 10 is fixedly connected with a universal wheel 5.

The working principle is that when going upstairs, the box body 1 is driven by pulling the pull rod 2, so that the roller 6 rolls on the ground, when the roller reaches a stair step, the roller 6 on the left side is subjected to resistance of the step, the connecting rod 9 and the roller 6 form a planetary gear device to start anticlockwise rotation, the roller 6 on the upper side reaches the top of the step on the next step, the roller 6 on the right side simultaneously anticlockwise rotates to replace the position of the roller 6 on the upper side in situ, the roller 6 on the left side also anticlockwise rotates to replace the position of the roller 6 on the right side in situ, the pull rod box continues to be pulled, and the planetary gear device repeats the steps, so.
