Detailed Description

As shown in figures 1-5, a portable child seat is suitable for children aged 3-6 years. Including chair body 1, chair body 1's back 12 sets up to the similar pattern with the animal, and chair body 1's seat 13 sets up to circular pattern, the preferred, and chair body 1's back 12 sets up to the little bear molding, and chair body 1's back 12 is circular promptly, and circular as the face type of little bear, sets up "two bear ears" on the upper portion of circular back, and chair body 1 collocation candy color to promote the interest of seat in children's use.

The lower part of the rear leg 11 of the chair body 1 is provided with an accommodating groove 2 which penetrates through the radial direction of the rear leg 11, the accommodating groove 2 is arranged in parallel with the backrest 12 of the chair body 1, and the accommodating groove 2 is a straight groove. A blocking piece 3 is arranged at the upper end of the accommodating groove 2, and at least one end of the blocking piece 3 is arranged to protrude out of the surface of the rear leg 11; a connecting shaft 4 penetrating through the accommodating groove 2 is arranged below the blocking piece 3, the connecting shaft 4 is arranged in parallel with the blocking piece 3, the connecting shaft 4 is positioned in the accommodating groove 2, an extensible piece 6 is arranged between the blocking piece 3 and the connecting shaft 4, the extensible piece 6 is respectively fixedly connected with the blocking piece 3 and the connecting shaft 4, rollers 5 are arranged at two ends of the connecting shaft 4, and the connecting shaft 4 is in bearing connection with the rollers 5; the inner side surface of the roller 5 is provided with convex stop levers 7 equally arranged in the radial direction, the distance between the surface of the stop lever 7 and the surface of the rear leg 11 is smaller than the convex part of the blocking member 3, and the distance between the inner side surface of the roller 5 and the surface of the rear leg 11 is larger than the convex part of the blocking member 3. When the chair body 1 is stressed, the telescopic piece 6 deforms and shortens, the chair body 1 sinks, and the stop rod 7 on the roller 5 is in contact with the protruding part of the stop piece 3, so that the roller 5 is clamped, and the chair is prevented from sliding when a child sits down.

Further, the lower end of the accommodating groove 2 extends to the end surface of the bottom of the rear leg 11; the middle part of the connecting shaft 4 is provided with a limiting block 8, and a limiting cavity 80 matched with the limiting block 8 is arranged in the accommodating groove 2. The limiting block 8 is annular, the limiting block 8 is fixedly arranged in the middle of the connecting shaft 4, the diameter of the limiting block 8 is larger than that of the connecting shaft 4, the thickness of the limiting cavity 80 is also larger than that of a cavity where the connecting shaft 4 is located, and the limiting block 8 can be prevented from moving left and right; therefore, the connecting shaft 4 and the roller 5 can be prevented from moving left and right during rotation, which is beneficial to the stability of the roller 5.

11 bottom end faces of back leg are provided with limiting plate 9, and limiting

plate

9 and 11 bottom end face fixed connection of back leg, limiting plate 9 prevent to damage because of extensible member 6, perhaps extensible member 6 and connecting axle 4 with stop 3 when breaking away from, connecting axle 4 break away from and put and accomodate groove 2, cause the seat can not normally move, limiting plate 9 is favorable to connecting axle 4 and gyro wheel 5's normal use, and timber or plastics material are chooseed for use to limiting plate 9.
