Description

A portable folding stroller

technical field

The invention relates to a baby carriage, in particular to a portable folding baby carriage.

Background technique

Children generally need adult care before they learn to walk stably. In order to facilitate the care of children at this stage, many families have generally begun to use strollers. Due to the large size of the stroller when working, it will take up a lot of space when not in use. Therefore, the stroller has gradually developed towards a foldable direction. The traditional stroller is bulky and heavy after being folded, and it is not easy to carry.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a folding stroller that is easy to carry. When the stroller is folded, the armrest is first pushed to the side of the seat plate, and the armrest is rotated around the hinge joint with the seat plate, so that the armrest is connected to the seat plate. Press the upper rod of the push handle into the lower rod of the push handle, and push the lower rod of the push handle to the side of the backrest board, and the lower rod of the push handle rotates around the hinge joint with the lower rod seat, and the lower rod of the push handle rotates At the same time, push the backboard to rotate, so that the backboard and the armrest are in close contact. When one side of the wheel moves, the slider drive seat drives the front foot slider to move to the front wheel side, and drives the two front foot rods to rotate around the hinge joint between the two front foot rods and the connecting seat, so that the two front foot rods are closed, and the two front foot sliders are corresponding to each other. When the front foot rod slides on the front foot rod, it drives the pull rod to move, and the pull rod drives the rear foot link rod two to rotate to the front wheel side, and drives the rear wheel to fold, and the baby carriage of the present invention is folded. Together, the front wheel and the rear wheel are concentrated in one place, and the front foot rod, the rear foot link rod 1 and the rear foot link rod 2 are folded together. , which solves the technical problem that the traditional baby carriage is bulky and inconvenient to carry after being folded.

The object of the present invention can be realized through the following technical solutions:

An easy-to-carry folding stroller includes a seat board, two seat support rods are hinged on the bottom of the seat board, and one end of the two seat support rods away from the seat board is respectively connected to both sides of the connection seat.

A slider drive seat is arranged between the two front foot sliders, the two ends of the slider drive seat are respectively hinged with the front foot slider, and the top of the slider drive seat is connected to one end of the push handle forefoot folding linkage rod Hinged, the other end of the front foot folding link rod of the push handle is hinged with the middle of the lower rod of the push handle, the bottom of the connecting seat is fixedly installed with two rear foot rod seats, and the rear foot rod seat is hinged with the rear foot link rod The first and second rear foot linkage rods, the ends of the first and second rear foot linkage rods away from the rear foot rod seat are respectively hinged with the rear wheel seat, and the rear wheel seat is mounted with a rear wheel.

Further, the first linking rod of the rear foot and the second linking rod of the rear foot are parallel to each other.

Further, one end of the seating board is hinged with a backrest board, and the other end of the seating board is hinged with an armrest 1 .

Further, a hook is fixedly installed on the lower rod of the push handle, a slot is formed on the backboard, and the hook is clipped with the slot.

Further, two pull rods are hinged on the slider drive base, and one end of the pull rod away from the slider drive base is hinged with the middle part of the second link rod of the rear foot.

Further, the working method of the stroller specifically includes the following steps:

When the stroller is folded, first push the armrest to the side of the seat board, and then rotate the armrest around the hinge joint with the seat board, so that the armrest and the seat board are in close contact, and push the upper rod of the push handle into the lower part of the push handle. Push the lower rod of the push handle to the side of the backrest board, rotate the lower rod of the push handle around the hinge joint with the lower rod seat, and push the lower rod of the push handle to rotate the backrest board while rotating, so that the backrest board and the armrest are tightly connected. Abutting, push the lower rod of the handle to push the front foot folding linkage rod of the push handle to move to the front wheel side; The front wheel moves on one side, and drives the two front foot rods to rotate around the hinge joint with the connecting seat, so that the two front foot rods are folded, and the two front foot sliders slide on the corresponding front foot rods while driving the pull rod to move, and the pull rod drives the rear foot. The second linkage rod rotates to the front wheel side, and drives the rear wheel to fold, and the folding is completed.

Beneficial effects of the present invention:

In the stroller of the present invention, the first handrail, the backrest plate and the lower rod of the push handle are close together after folding, the front wheel and the rear wheel are concentrated in one place, and the front foot rod, the rear foot link rod 1 and the rear foot link rod 2 are folded and concentrated. The stroller is easy to fold, small in size after folding, large in size when unfolded, light in weight, and easy to carry.
