Description

A hospital bed with adjustable length

technical field

The utility model relates to a medical auxiliary tool, in particular to a length-adjustable hospital bed.

Background technique

The general length of common sick bed used now is fixed, and for taller patient, uses sick bed in the prior art, and patient may stretch out leg because sick bed is too short, thereby affects the patient's rest, and then is unfavorable for patient's rehabilitation.

Utility model content

Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a stretchable hospital bed whose length can be adjusted according to needs.

In order to achieve the above object, the utility model takes the following technical solutions:

A length-adjustable hospital bed, comprising: a lower bed board, a bedside rail, an upper bed board, and bed legs. It is located above the lower bed board; four bed legs are provided at the four corners below the lower bed board, and two bed legs are provided at the two corners below the head of the upper bed board; the inner end of the lower bed board is below Two sliding rod seats are arranged on both sides, and a lower bearing seat is arranged in the middle below the inner end of the lower bed board; two upper sliding rod seats are arranged on both sides below the bed head end of the upper bed board, and the upper bed board There is an upper bearing seat in the middle of the bed head end; each lower bar seat is provided with a slide bar, one end of each slide bar is fixed on the upper slide bar seat by a bolt, and the other end of the slide bar is provided with a limit A block plays a position-limiting role; a threaded rod is arranged on the upper bearing seat, one end of the threaded rod with a crank handle is arranged on the upper bearing seat, and the other end of the threaded rod is arranged on the lower bearing seat. Turning the crank handle by hand can make the threaded rod screw in or out, so that the upper bed board can be driven in or out, and then the whole bed can be lengthened or shortened.

Further, the lower end of each bed leg is provided with wheels.

When in use, turn the crank handle counterclockwise by hand, and turn the threaded rod to unscrew the threaded rod, so that the threaded rod moves away from the lower bearing seat while the threaded rod is unscrewed, driving the upper bed board to move away from the lower bed board, and then Stretch the entire bed to make the bed stretch to the appropriate length for the patient; turn the crank handle clockwise by hand to screw in the threaded rod, so that the threaded rod moves in the direction close to the lower bearing seat while screwing in, driving the upper bed plate to Move near the direction of the lower bed board, and then shorten the whole bed, so that the length of the whole bed is reduced. Therefore, by turning the crank handle, the threaded rod can be screwed in or out, thereby driving the upper bed board to move in or out, and then the whole bed can be shortened or extended.

The utility model can meet the needs of patients with different heights for different lengths of hospital beds, and has simple structure and convenient operation.

Detailed ways

Below in conjunction with accompanying drawing, by embodiment, the technical scheme of the present utility model is described in further detail:

As shown in Figures 1 to 5, a length-adjustable hospital bed includes: a lower bed board 1, a headboard 2, an upper bed board 3, and bed legs 4; The bedside of the above-mentioned upper bed board 3 is also provided with a headboard gear 2, and the upper bed board 3 is arranged on the top of the lower bed board 1; four corners of the lower bed board 1 are provided with four bed legs 4, and There are two bed legs 4 at the two corners below the head of the bed; two sliding rod seats 13 are arranged on both sides below the inner end of the lower bed board 1, and a lower bearing is arranged in the middle below the inner end of the lower bed board 1 Seat 14; Two upper slide bar seats 9 are provided below the head end of the upper bed board 3, and an upper bearing seat 10 is provided in the middle below the head end of the upper bed board 3; each lower bar seat 13 is provided with There is a slide bar 6, one end of each slide bar 6 is fixed on the upper slide bar seat 9 by a bolt 12, and the other end of the slide bar 6 is provided with a limit block 8, which acts as a limiter; on the upper bearing seat 10 A threaded rod 7 is provided, and one end of the threaded rod 7 with a crank handle 11 is located on the upper bearing seat 10, and the other end of the threaded rod 7 is located on the lower bearing seat 14. Turning the crank handle 11 by hand can make the threaded rod 7 screw in or out, so that the upper bed board 3 can be driven in or out, and then the whole bed can be extended or shortened.

Further, wheels 5 are provided under each bed leg 4;

When in use, turn the crank handle 11 counterclockwise by hand, turn the threaded rod 7, and thread the threaded rod 7 to unscrew, so that the threaded rod 7 moves away from the lower bearing seat 14 while the threaded rod 7 is unscrewed, and drives the upper bed board 3 to move away from the lower bearing seat 14. Move in the direction of the bed board 1, and then elongate the bed; turn the crank handle 11 clockwise by hand, so that the threaded rod 7 is screwed in, so that the threaded rod 7 moves in the direction close to the lower bearing seat 14 while screwing in, driving the upper bed board 3. Move towards the direction close to the lower bed board 1, thereby shortening the whole bed, and reducing the length of the whole bed; in this way, by turning the crank handle 11, the threaded rod 7 can be screwed in or out, thereby driving the upper bed board 3 to move in or out , thereby shortening or elongating the entire bed.

The above-mentioned embodiments are only explanations and descriptions of the technical solution of the utility model, and cannot be understood as limitations on the technical solution of the utility model. Any modification made on the basis of the utility model without departing from the basic spirit of the utility model belongs to the utility model The scope of the claims.
