Embodiment

[0025] as attached figure 1 As shown, the front leg support (1), the pull rod (2), the rear leg support (3), the seat board (4), the armrest support (5), and the backrest support (6), they together constitute two linked four-connected Rod folding structure. The front leg support (1), the pull rod (2), the rear leg support (3), and the seat plate (4) constitute the first four-link folding structure. The rear leg support (3), the seat board (4), the armrest support (5), and the backrest support (6) constitute the folding structure of the second four-link. The rear leg support (3) and the seat board (4) can be regarded as the shared connecting rods of the first four-link folding structure and the second four-link folding structure, realizing the first four-link folding structure and the second four-link folding structure. The effect of the linkage between the four-link folding structure. The joints of all the links are fixed by means of pivot joints, so as to realize the requi...

Abstract

The invention discloses a foldable frame structure applied to a portable baby carriage, and relates to the field of baby carriages. The foldable frame structure mainly solves the problems that a babycarriage is large in storage size after being folded, storage steps are tedious, and an injection-molded piece is high in production cost and short in service life. The foldable frame structure applied to the portable baby carriage comprises front leg brackets (1), pulling rods (2), back leg brackets (3), a seat board (4), armrest brackets (5) and backrest brackets (6), and is characterized in that the front leg brackets (1), the pulling rods (2), the back leg brackets (3), the seat board (4), the armrest brackets (5) and the backrest brackets (6) jointly form two linked four-connecting-rod folding structures. Locking mechanisms (7) are arranged between the front leg brackets (1) and the back leg brackets (3). A backup plate (8) is arranged on the backrest brackets (6).

Description

【Technical field】 [0001] The invention relates to the field of children's trolleys. 【Background technique】 [0002] Children's trolley is an important tool for carrying children on long and short distance trips and excursions. The existing design of children's trolleys has reached a certain height in terms of aesthetic appearance and comfort, but the folding structure design of the frame is not very ideal. The most common situation is that the storage volume after folding is compared with the unfolded volume before folding. After folding, the space compression rate is not high, and the occupied space is still large, making travel and travel difficult. Another common situation is that the functional parts of different parts, such as armrests and backrests, need to be folded or disassembled twice or even three times before they can be completely stored. The overall storage cannot be completed at one time, resulting in time-consuming and laborious storage. Another situation is...
