Description

Technical Field

[0001] The utility model relates to the technical field of hospital beds, in particular to a hand-cranked hospital bed. Background Art

[0002] The hand-cranked hospital bed adjusts the inclination of the bed board by rotating the handle, assisting the patient to change from a lying state to a sitting state, which is convenient for the patient to get up or eat.

[0003] Since the hand crank needs to be pulled outwards first when in use, and then rotated to control the angle of the bed board. After the adjustment of the bed board angle is completed, the handle is pushed back to its original position. The process of pushing and pulling the handle is relatively cumbersome, and if the handle is not pushed back to its original position after being pulled out, it will affect the walking of nearby people. Therefore, the handle needs to be pushed back to its original position after use.

[0004] Therefore, the traditional hand-cranked hospital bed can be improved to simplify the use of the hand crank. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hand-cranked hospital bed to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The hand-cranked hospital bed includes a bed body, a bed frame and a bed board. The bed board is rotatably connected to the bed frame, and the bending part of the bed board abuts against a push rod. The push rod is rotatably connected to the bed frame. A slot is formed on the bed frame, and a rotating rod is arranged in the slot. The rotating rod is threadedly connected with a round sleeve, and the round sleeve is rotatably connected to the push rod. A handle is arranged on the rotating rod, and the handle automatically retracts below the bed frame under the action of an adjusting member.

[0008] Preferably, the adjusting member includes a fixed disk fixed on the rotating rod, and a connecting rod is fixed on the fixed disk. A chute is formed on the connecting rod, and a collar is slidably connected to the connecting rod. A slider slidably connected to the chute is fixed on the collar, and the slider is fixed to the handle. A spring is sleeved on the connecting rod.

[0009] Preferably, one end of the spring abuts against an end block, and the other end abuts against the collar.

[0010] Preferably, an elastic rubber gasket is arranged on the part of the collar abutting against the fixed disk.

[0011] Preferably, balls are arranged on the part of the slider slidably connected to the chute.

[0012] Preferably, rubber anti-slip patterns protrude from the surface of the handle.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. After the angle adjustment of the bed board is completed in this application, the pulling force on the handle is released. Under the push of the elastic force of the spring, the round sleeve moves to abut against the fixed plate. At this time, the handle moves to the bottom of the bed and is hidden. After use, the handle does not need to be manually returned to its original position. Under the action of the elastic force of the spring, the handle can automatically return to its original position, which is more convenient and saves cumbersome steps.

[0015] 2. When using the handle in the present application, it is only necessary to pull the handle outwards, and the degree to which the handle is pulled out from the bottom of the bed is controlled by the operator. Therefore, the operator can make real-time adjustments according to his own needs, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] The utility model provides a technical solution, please refer to Figures 1-3 :

[0024] Hand-cranked hospital bed, including a bed body 1, a bed frame 2 and a bed board 3. The bed board 3 is rotatably connected to the bed frame 2, and the bed board 3 abuts against the bent portion of the push rod 15. The push rod 15 is rotatably connected to the bed frame 2. A slot 4 is provided on the bed frame 2, and a rotating rod 5 is provided in the slot 4. A circular ring 16 is rotatably connected to the outer wall of the rotating rod 5, and the circular ring 16 is slidably connected to the slot 4 in the vertical direction. The rotating rod 5 is threadedly connected with a round sleeve 14, and the round sleeve 14 is rotatably connected to the push rod 15. A handle 13 is provided on the rotating rod 5. The surface of the handle 13 protrudes with rubber anti-slip patterns, and the handle 13 automatically retracts below the bed frame 2 under the action of the adjusting member. When the rotating rod 5 rotates, under the restriction of the push rod 15, the round sleeve 14 moves, thereby driving the push rod 15 to rotate. The bent portion of the push rod 15 pushes the bed board 3 to rotate.

[0025] Embodiment 2:

[0026] Basically the same as the technical solution of Embodiment 1, the difference is that, as Figure 3 shown, the adjusting member includes a fixed disk 6 fixed on the rotating rod 5, and a connecting rod 7 is fixed on the fixed disk 6. A chute 9 is provided on the connecting rod 7, and a collar 11 is slidably connected to the connecting rod 7. A slider 12 slidably connected to the chute 9 is fixed on the collar 11. Ball bearings are provided on the part of the slider 12 slidably connected to the chute 9. The slider 12 is fixedly connected to the handle 13. A spring 10 is sleeved on the connecting rod 7. One end of the spring 10 abuts against the end block 8, and the other end abuts against the collar 11. An elastic rubber gasket is provided on the part of the collar 11 abutting against the fixed disk 6. Under the elastic force of the spring 10, when the collar 11 is not subjected to external force, the collar 11 can move along the connecting rod 7 until the side wall of the collar 11 abuts against the side wall of the fixed disk 6. At this time, the handle 13 retracts below the bed body 1 and is hidden.

[0027] In summary, when adjusting the angle of the bed board 3 in this embodiment, the handle 13 can be pulled outwards. At this time, the spring 10 is compressed. Then the handle 13 can be rotated, so that the connecting rod 7 and the rotating rod 5 rotate together. Since the round sleeve 14 is restricted by the push rod 15, the round sleeve 14 moves along the rotating rod 5, resulting in the rotation of the push rod 15. The bent portion of the push rod 15 pushes the bed board 3 to rotate, thereby changing the angle of the bed board 3.

[0028] After the angle adjustment of the bed board 3 is completed, release the pulling force on the handle 13. Under the elastic force of the spring 10, the round sleeve 14 moves to abut against the fixed disk 6. At this time, the handle 13 moves below the bed body 1 and is hidden.

[0029] The foregoing description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather should be accorded the widest scope consistent with the principles and novel features disclosed herein.
