[0017] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] As Figs. 1-2 shown, the utility model provides a kind of baby stroller folding device, it includes cylindrical hollow pipe 1, the center area of cylindrical hollow pipe 1 is provided with shrink tube 4, and movable pin 3 is arranged in the both ends of cylindrical hollow pipe 1, and two ends of cylindrical hollow pipe 1 are provided with driving part 2, and rotating seat 5 is connected to two driving parts 2, and rotating seat 5 is sleeved on cylindrical hollow pipe 1;

[0019] Cylindrical hollow pipe 1 is provided with two through slots 11;

[0020] Movable pin 3 is provided with protruding part 31;

[0021] Driving part 2 is provided with arc-shaped through slot 21;

[0022] Rotating seat 5 is provided with button 6 with spring, and button 6 corresponds to shrink tube 4;

[0023] Protruding part 31 is pasted with arc-shaped through slot 21 after passing through through slot 11.

[0024] The principle and use process of the utility model:

[0025] The device is usually installed below baby stroller sleeping basket, movable pin 3 can be movable in the hole of both sides of mounting seat, and the folding function of baby stroller is completed by the extension or shrinkage of movable pin 3, when folding, just press button 6, then rotating seat 5 is unlocked, and rotating seat 5 can be rotated, because rotating seat 5 is connected with driving part 2, so driving part 2 is also rotated, and protruding part 31 of movable pin 3 is affected by arc-shaped through slot 21, and movable pin 3 moves inward under the influence of through slot 11 track, so as to separate from both sides of mounting seat, and folding is carried out.

[0026] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
