Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model discloses a folding bed.

Referring to fig. 1 to 5, a folding bed includes: the bed comprises a bed framework, a back supporting mechanism and a plurality of bed boards 5, wherein the bed framework comprises an inner framework 2 and an outer framework 1, the inner framework 2 is rotatably connected with the outer framework 1, so that the inner framework 2 can relatively rotate relative to the outer framework 1;

the bed skeleton includes inner frame 2 and exoskeleton 1, inner frame 2 with exoskeleton 1 all is C shape, and the open end of the two rotates the connection, the both sides width at 2 opening places of inner frame is less than the both sides width at 1 opening places of exoskeleton.

After inner frame 2 and exoskeleton 1 are folded, the size of inner frame 2 is less than exoskeleton 1 for inner frame 2 can be embedded into exoskeleton 1, and thus the volume after folding is smaller.

The bed boards 5 are respectively arranged above the inner framework 2, and the bed boards 5 are arranged above the outer framework 1.

The back supporting mechanism comprises a bottom support 21, a back support 22 and a first electric push rod, one side, far away from the bottom support 21, of the back support 22 is rotatably connected with a head support 23, the bottom support 21, the back support 22 and the head support 23 are sequentially arranged from the direction far away from the outer framework 1, the back support 22 is rotatably connected with the bottom support 21, a bed board 5 is respectively and fixedly connected above the bottom support 21, the back support 22 and the head support 23, a sliding strip 41 is fixedly connected below the bottom support 21, the sliding strip 41 is slidably connected with the inner framework 2, and the sliding direction is parallel to the inner framework 2;

the first electric push rod is fixed on the slide bar 41, an output shaft of the first electric push rod is fixed on the back support 22, a connecting rod 24 is arranged between the back support 22 and the inner frame 2, and two ends of the connecting rod 24 are respectively connected to the back support 22 and the inner frame 2;

the reason that is in the frictional force when reducing draw runner 41 and slides, be provided with a plurality of gyro wheels 42 on the

draw runner

41, 2 open-ended both sides of inner frame are the channel-section steel form, gyro wheel 42 roll connection is in the channel-section steel form opening of inner frame 2.

Further, in order to improve that the rollers 42 evenly share the stress on the sliding bars 41, the number of the rollers 42 is four, two sliding bars 41 are respectively arranged below the bottom framework, two sliding bars 41 are located at two sides of the bottom framework, and two rollers 42 are respectively arranged at two ends of one sliding bar 41.

The working principle of the back support function is as follows: when back support is required, the first push rod 31 is extended, and due to the limitation of the length of the connecting rod 24, on one hand, the bottom bracket 21 slides away from the outer frame 1 with the help of the slide bar 41 and the roller 42, and on the other hand, the back bracket 22 rotates upward relative to the bottom bracket 21 and is obliquely arranged relative to the inner frame 2, so that the head bracket 23 moves upward along with the back bracket 22 in response to the sitting posture of the patient.

This arrangement reduces the risk of the waist of the person moving away from the exoskeleton 1, and thus reduces the risk of the waist of the person being pinched, since the rollers 42 cause the bottom bracket 21 to move away from the exoskeleton 1 at the same time as the back support function.
