Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them; based on The embodiments of the present invention and all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

As shown in Figures 1-3, the present invention discloses a baby stroller structure with a foldable handle that can be retracted and lowered in one piece, including: a stroller frame with two states: unfolded and folded. The top ends of both sides of the stroller frame The installation is provided with a fixed joint 5. The bottom end of the handle tube 6 is rotated and inserted on the fixed joint 5. The top of the handle tube 6 is connected with a bending device 7. When the cart frame is in In the unfolded state, the limiting boss 8 provided on the bottom side wall of the handle tube 6 is in position-limiting conflict with the top wall of the fixed joint 5. When the stroller frame is in the folded state, the folding The bending device 7 bends and drives the handle tubes 6 on both sides to rotate. The limiting boss 8 of the handle tube 6 rotates to a position corresponding to the chute 50 provided on the fixed joint 5. The handle tube 6 6. Slide down along the fixed joint 15 to close it.

Side brackets are symmetrically arranged on both sides of the stroller frame, and X-shaped cross tubes 9 and X-shaped cross flat irons 10 are connected between the side brackets on both sides. The side brackets on each side include Front branch pipe 1 and rear branch pipe 2. The bottom ends of the front branch pipe 1 and the rear branch pipe 2 are respectively equipped with front wheel assemblies 3 and rear wheel assemblies 4. The top of the front branch pipe 1 is fixedly connected to a fixed joint 5, so The top end of the rear branch pipe 2 is rotatably connected to a fixed joint 5.

The X-shaped cross tube 9 is hingedly connected at its middle position, the front end of the X-shaped cross tube 9 is rotationally connected to the bottom end of the front branch pipe 1, and the rear end of the The side walls are rotatably connected.

The X-shaped cross flat iron 10 is hingedly connected at its middle position. The bottom end of the X-shaped cross flat iron 10 is rotationally connected to the bottom end of the rear branch pipe 2. The side walls of the joint 11 are connected in a rotational manner, and a foot pedal 17 is installed at the middle position of the X-shaped cross flat iron 10 to facilitate the user to step down on the foot pedal 17 to open the cart frame for use.

The sliding joint 11 is slidably mounted on the rear branch pipe 2. One end of the sliding joint 11 is rotatably connected to the flat iron 12, and the other end of the flat iron 12 is rotatably connected to the draw tube 13 and the flat iron 2 14 respectively. One end of the draw tube 12 is rotatably connected to the front branch pipe 1, and the other end of the flat iron 14 is rotatably connected to the fixed joint 2 15. The fixed joint 2 15 is fixedly installed on the rear branch pipe 2.

The fixed joint 5 is provided with a removable buckle-mounted shower seat assembly 16, which facilitates the buckle installation of the shower seat assembly 16 and facilitates the folding of the stroller frame when dismantled.

The present invention is implemented as follows: when the stroller frame is folded for use, the buckle-mounted shower seat assembly 16 on the stroller frame is removed in advance, and the bending device 7 is used to unlock and bend, thereby driving the handle tube 6 to exert downward force, so that The side brackets on both sides are folded close together, so that during the folding and folding process of the X-shaped cross flat iron 10, the sliding joint 11 is pushed to slide upward along the rear branch pipe 2. The sliding joint 11 slides upward and connects the side brackets on both sides with the X-shaped cross pipe 9. When the sliding joint 11 slides upward, the flat iron 12 is rotated and folded downward, so that under the action of the flat iron 2 14 and the pull tube 13, the rear branch pipe 2 is folded closer to the forward branch pipe 1 and the two sides of the flat iron 12 are folded. The side brackets are folded close together, and the rotation limit boss 8 of the handle tube 6 corresponds to the position of the chute 50 provided on the fixed joint 1 5, so that the handle tube 6 slides downward along the fixed joint 5 to close, thereby realizing the vehicle frame. Folding; during the unfolding process of the stroller frame, the user presses the foot pedal 17 downward, thereby causing the X-shaped cross flat iron 10 to rotate and open, thereby linking the side brackets on both sides and the rear branch pipe to unfold away from the front branch pipe, and the handle The tube 6 slides upward along the fixed joint 5, so that the limiting boss 8 provided on the bottom side wall of the handle tube 6 is in limited conflict with the top wall of the fixed joint 5, and then the shower seat assembly 16 is installed and ready for use. Using this technical solution, the folding and closing of the cart frame is realized by the bending device driving the handle tube to bend and rotate. The folding operation of the cart frame is convenient. To unfold the cart frame, you only need to step on the foot pedal until the cart frame is opened, and Just pull the handle upward to the limit position. This design has a simple structure, is easy to install and process, is easy to operate, and is more flexible.

Finally, it should be noted that the above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, there are still many problems in this field. It should be understood by those of ordinary skill that the present invention can still be modified or equivalently substituted; and all technical solutions and improvements that do not depart from the spirit and scope of the present invention shall be covered by the claims of the present invention.
