Detailed Description

The structure and the working principle of the draw-bar box type folding bed provided by the invention are further explained in detail with the attached drawings.

Referring to fig. 1, fig. 2 and fig. 3, the structure of the draw-bar box type folding bed provided by the present invention is schematically illustrated. The structure of the draw-bar box type folding bed comprises a box bottom 1 and a box cover 2 which are fixedly connected by a shaft 3, and a draw-bar box body which is composed of a draw bar 4 which can be pushed in and pulled out; preferably, U-shaped brace mechanisms 6 fixed by shaft structures 5 are respectively arranged at two sides of the inner parts of the box bottom and the box cover close to the side arms thereof (namely, connecting rods 8 are arranged at the bottoms of the brace mechanisms at two sides of the inner parts of the box bottom and the box cover to form a U-shaped conjoined structure), the brace mechanisms can be pulled out from the box bottom and the box cover which are laid by the shaft structures 5 to form a stable support leg as shown in fig. 2 and 3, and the brace mechanisms 6 are arranged close to the side arms 22 of the box bottom or the box cover to form a stable support leg, namely, a fixing mechanism which is formed by a rotating shaft 63 and a supporting plate 62 and can be pressed at the bottom of the box bottom or the box cover when not used is arranged at the top of the support leg; a display board 71 which can be pulled out and pushed in the same direction as the pull rod 4 (in a pulled-out state as shown in the figure), used for putting on feet when a person lies down or used for placing a pillow is arranged in the cover body 21 of the box cover 2 provided with the pull rod 4, and the pull rod 4 and the display board 71 are in a separated state (can be pulled out respectively).

The use principle is as follows: the draw-bar box type folding bed is characterized in that on the basis of a traditional draw-bar box, support bar mechanisms fixed by shafts are respectively arranged on two sides of the interior of a box bottom and a box cover, the support bar mechanisms can be folded on the inner surfaces of the box bottom and the box cover, when the box cover is lifted flat and forms a bed surface with the box bottom, the support bar mechanisms are rotated to be perpendicular to the bed surface to form bed (support) legs, and meanwhile, a support plate 62 is rotated out through a rotating shaft 63 to form a fixing mechanism of the bed (support) legs (a stable support leg can be formed by fixing a support bar 61 between a left bed (support) leg and a right bed (support) leg). In order to adapt to lying of a human body and increase the length of the bed surface, a display board 71 which can be pulled out and pushed in is arranged in the cover body 21 of the box cover and can be used for stepping or placing a pillow. The draw-bar box type folding bed is very convenient to use, and provides convenience for a traveler or other people in need of lying and resting.

In the structure constituting the above-described draw-bar box type folding bed,

the U-shaped display board support rods 9 fixed by the shafts 51 are arranged on the lower side surface of the display board 71, after the display board 71 is pulled out through the outlet at the outer edge of the box bottom, a bed head and/or a bed tail area is formed, the display board support rods 9 are folded out at the lower side of the display board, the display board can be effectively supported, the flatness of the bed surface is improved, and the comfort level of lying of a human body is increased;

in order to further meet the use of the persons with higher height, a second display plate 72 which can be pulled out and pushed in is arranged in the bottom cover 11 which forms the pull rod box bottom 1, namely, the length of the bed surface is increased to meet the requirement; a U-shaped second display board support rod 92 fixed through a shaft is arranged on the lower side of the second display board 72 and can be pulled out when in use;

as shown in fig. 4 and 5, the second structure schematic diagram of the draw-bar box type folding bed is shown, that is, the structure of the draw-bar box type folding bed comprises a box bottom 1 and a box cover 2 connected by a shaft 3, and a draw-bar box body formed by a draw bar 4 capable of being pushed and pulled out; the two sides of the inside of the box bottom and the box cover (and the two sides are separated from the side arms 22 of the box body by a certain distance L) are respectively provided with a stay bar mechanism 6 fixed by a shaft structure 5 (namely, the bottom of the stay bar mechanism 6 forming the two sides of the inside of the box bottom and the box cover is provided with a connecting rod 8 to form a U-shaped conjoined structure), the stay bar mechanism can be placed in the box bottom and the box cover and can be pulled out to form a splayed support leg as shown in figure 5, and two sides forming the top of the support leg are provided with a fixing mechanism which is formed by a rotating shaft 63 and a support plate 62 and can be pressed on the bottom of the box bottom or the box cover when not used (or a stable support leg can be formed by fixing a support bar 61 between the left bed leg and the right bed leg); a display board 71 which can be pulled out and pushed in (pulled out state as shown in the figure), used for putting feet or used for placing a pillow is arranged on the other side of the cover body of the box cover 2 provided with the pull rod 4. The display board 71 of the pull rod box type folding bed with the structure is not arranged together with the pull rod 4, so that the structure at the pull rod is simpler, namely, the pull rod is pulled out or pushed in without considering the in and out of the display board 71. Of course, in the structure of the draw-bar box type folding bed, in order to further meet the use requirements of people with higher height, a second display plate 72 which can be pulled out and pushed in is arranged in the bottom cover of the box bottom 1; at least one (preferably two) second board brace rods 92 fixed by the shaft 51 are arranged at the lower side of the second board 72, and when two board brace rods 92 are arranged, the connecting rod 82 is also arranged at the bottom of the two board brace rods to form a connected structure for improving the stability of the two board brace rods, namely, the brace rods are in a U (or 'door') shape;

in order to improve the bearing capacity of the bed surface, the box bottom and the box cover are made of hard materials, such as light aluminum alloy, plastic steel, glass fiber or carbon fiber, so that the weight is light, the box is convenient to carry during business trips, and the materials are high in mechanical strength, wear-resistant and long in service life; or as shown in fig. 3 and 5, the inside of the box bottom and the box cover is provided with a support framework 10, the support framework is fixedly connected with a rotating shaft 5 shaft sleeve which forms the support rod mechanism, and the support framework and the rotating shaft are integrated into a whole structure, so that the integral bearing strength of the folding bed is improved.
