Abstract

A baby carriage that can be folded horizontally and vertically, the upper end of the second rear link [3] is pivotally connected to the first sliding sleeve [4], and the first sliding sleeve [4] is slidably sleeved on the first rear leg [5], the upper end of the first rear link [2] is pivotally connected with the second sliding sleeve [9], and the second sliding sleeve [9] is slidably sleeved on the second rear leg [6]; When the stroller is folded, the two sliding sleeves slide along the corresponding two rear legs respectively. When the stroller is in the open state, the position of the sliding sleeve is greatly lowered, which does not affect the setting of the seat frame, and the seat frame can also protrude toward the rear of the rear legs, so the rear cross brace of the utility model becomes smaller, and the production cost is also reduced .

technical field

The utility model relates to a baby carriage.

Background technique

In the prior art, the umbrella handle vehicle includes a first front leg, a second front leg, a first front wheel arranged at the lower end of the first front leg, a second front wheel arranged at the lower end of the second front leg, a first rear leg, second rear leg, first rear wheel arranged at the lower end of the first rear leg, second rear wheel arranged at the lower end of the second rear leg, first push handle bar, second push handle bar, front a first support rod pivotally connected to the first front leg and the first rear leg at the rear portion, a second support rod pivotally connected to the second front leg and the second rear leg at the front portion and the rear portion, respectively, The lower cross brace and the rear cross brace, the two front ends of the lower cross brace are pivotally connected to the first front leg and the second front leg respectively, and the two rear ends of the lower cross brace are respectively connected to the second front leg One rear leg is pivotally connected to the second rear leg, the first push handle rod is pivotally connected to the upper end of the first rear leg, and the front end of the first push handle rod is connected to the rear end of the first front leg. pivotally connected, the second push handle rod is pivotally connected to the upper end of the second rear leg, the front end of the second push handle rod is pivotally connected to the rear end of the second front leg, the first push handle rod and A seat frame is arranged between the second push handle bars. After the rear cross support is pivotally connected at the intersection by the first rear link and the second rear link, the lower end of the first rear link is pivoted to the first rear leg. connection, the lower end of the second rear link is pivotally connected to the second rear leg, the upper end of the first rear link is pivotally connected to the higher position of the second rear leg, and the second rear link The upper end is pivotally connected to the higher position of the first rear leg, so that the rearmost end of the seat frame must be positioned in front of the upper end of the rear cross brace, and the seat frame can only be arranged in a sitting position, and cannot be arranged in a lying position. position, so the setting of the rear cross affects the horizontal position of the seat frame being set on half or full reclining. If the top of the rear cross is to be moved down, a parent-child support must be provided, which will make the structure of the product complex and increase the production cost.

Contents of the invention

The purpose of the utility model is to provide a horizontally and longitudinally foldable stroller with a simple structure and a seat frame that can be set flat or half-lying.

The technical scheme of the utility model is: a baby carriage that can be folded horizontally and vertically, including a first front leg, a second front leg, a first front wheel arranged at the lower end of the first front leg, a the second front wheel at the lower end, the first rear leg, the second rear leg, the first rear wheel arranged at the lower end of the first rear leg, the second rear wheel arranged at the lower end of the second rear leg, the first a push handle bar, a second push handle bar, a first support bar pivotally connected to the first front leg and the first rear leg at the front and rear parts, and a first support bar at the front and rear parts to the second front leg and the second rear leg, respectively The second support bar, the lower cross brace, and the rear cross brace are pivotally connected. The two front ends of the lower cross brace are respectively pivotally connected to the first front leg and the second front leg. The lower cross brace The two rear ends of the brace are pivotally connected to the first rear leg and the second rear leg respectively, the first push handle rod is pivotally connected to the upper end of the first rear leg, and the front end of the first push handle rod It is pivotally connected to the rear end of the first front leg, the second push handle is pivotally connected to the upper end of the second rear leg, and the front end of the second push handle is connected to the rear end of the second front leg are pivotally connected with each other, a seat frame is arranged between the first push handle bar and the second push handle bar, and after the rear cross support is pivotally connected by the first rear connecting rod and the second rear connecting rod The lower end is pivotally connected to the first rear leg, the lower end of the second rear link is pivotally connected to the second rear leg, and the upper end of the second rear link is pivotally connected to the first sliding sleeve , the first sliding sleeve is slidably sleeved on the first rear leg, the upper end of the first rear link is pivotally connected with the second sliding sleeve, and the second sliding sleeve is slidably sleeved on the second On the two rear legs; a locking mechanism is provided between the second sliding sleeve and the second rear leg, or a locking mechanism is provided between the first sliding sleeve and the first rear leg; when the stroller is in an open state, the The locking mechanism is in the locked state; and when the locking mechanism is in the unlocked state, the two sliding sleeves slide along the corresponding two rear legs respectively so that the stroller is in the folded state.

Compared with the prior art, the utility model has the following advantages:

Since the upper end of the second rear link is pivotally connected to the first sliding sleeve, the first sliding sleeve is slidably placed on the first rear leg, and the upper end of the first rear link is connected to the first sliding sleeve. The two sliding sleeves are pivotally connected, and the second sliding sleeve is slidably set on the second rear leg, so that during the folding process of the stroller, the sliding sleeve will move along the rear leg without affecting the folding of the whole vehicle. And when the stroller is in the opened state, the position of the sliding sleeve is greatly reduced, which does not affect the setting of the seat frame, and the seat frame can also protrude to the rear of the rear legs to form a half-lying or fully lying seat. Therefore, the rear cross of the utility model The support becomes smaller, and the production cost is also reduced.
