Folding type bedstead and air bed with the folding type bedstead

Abstract

The invention discloses a folding bed frame which is positioned on a supporting surface and is used for supporting a bed body. The folding bed frame comprises a plurality of supporting units that are juxtaposedly arranged along the extending direction, and extending units which are connected between every two adjacent supporting units and can movably change the relative distance between every twoadjacent supporting units along the extending direction, wherein the supporting units comprise a plurality of supporting frames which are connected juxtaposedly, each supporting frame comprises two vertical rods, an upper cross rod connected with the top ends of the two vertical rods, and a lower cross rod connected between the two vertical rods; each extending unit comprises an upper cross rod pivoted on the supporting frame outside the first supporting unit, a first connecting bar which is arranged between the lower cross rods of the supporting frames outside the second supporting unit adjacent to the first supporting unit, a lower cross rod pivoted on the supporting frame outside the fist supporting unit, and a second connecting bar which is arranged between the upper cross rods of thesupporting frame outside the second supporting unit. In addition, the invention also discloses an inflating bed body with the folding bed frame. The invention has the advantages of simple structure, stable integral structure, and the like.

Description

technical field [0001] The invention relates to a foldable bed frame and an air bed with the foldable bed frame. Background technique [0002] The folding bed frame of the prior art, such as patent No. 02107950.1, discloses a telescopic bed frame, which includes several support units parallel and juxtaposed along a telescopic direction and a movable support unit that can change the relative distance between the support units along the telescopic direction. Contraction unit, the support unit includes two upright rods and a cross bar connected to the upright rods, the telescopic unit includes two telescopic frames connected to the corresponding upright rods of the adjacent support unit, the telescopic frame has four mutual pivots The connected connecting rod is shaped like two parallel X shapes, and the connecting rod is close to the end of one of the upright rods of the adjacent support unit to form a connection part, and is close to the other end of the other corresponding u...

Problems solved by technology

[0004] However, the shrinking structure of this kind of shrinking bed frame is composed of four connecting rods that are pivotally connected to each other. The structure is too complicated, and too many parts are used, which greatly improves the manufacturing cost and production efficiency

[0005] In addition, the contraction structure of this kind of retractable bed frame only pays attention to the fixed connection in the telescopic direction, but there is no good fixed connection method for the direction perpendicular to the telescopic direction, which may easily cause the bed frame to loosen.

Although this defect is also improved in the patent literature, such as connecting a connecting rod between the telescopic frames, this method can only keep the distance between the telescopic frames stable, and has no effect on the stability of the overall telescopic unit. improve
