DETAILED DESCRIPTION

[0018] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions based on the principles of the present invention should be included in the scope of protection of the present invention. It should also be noted that improvements and modifications that do not depart from the principles of the present invention by ordinary skill in the art should also be considered within the scope of protection of the present invention.

[0019] like Figures 1 to 3 As shown, a medical bed with adjustable guardrail height includes a bed frame body 1 and a guardrail 2 movably arranged on the bed frame body 1, the guardrail 2 includes a movable rod 3 movably arranged on the bed frame body 1 and a lifting rod 4 slidably engaged with the movable rod 3, a cross bar 5 movably arranged above the lifting rod 4, and hollow chambers are provided inside the cross bar 5 and the lifting rod 4, a limit mechanism is provided inside the lifting rod 4, and a control component for controlling the state of the limit mechanism is provided on the cross bar 5.

[0020] like Figure 1 As shown, the maintenance and fixation of the vertical state of the guardrail 2 is an upper fixing method in the prior art, specifically, a connecting block with a hole is fixed on the outermost lifting rod 4, and a limiter is fixed on the cross bar 5 at a position corresponding to the block. The limiter can pop out a block that is adapted to the hole on the connecting block. Through the cooperation of the limiter and the connecting block, the angle between the lifting rod 4 and the cross bar 5 can be fixed, that is, the vertical state of the guardrail 2 is fixed. There is an active button on the limiter. Pressing the active button can retract the block into the limiter, thereby releasing the fixation of the vertical state of the guardrail 2 and making it movable. When it is necessary to adjust the height of the guardrail 2 in the vertical state, squeeze the control component by hand, and the control component will control the working state of the limit mechanism, thereby releasing the fixed state between the lifting rod 4 and the movable rod 3, and making it movable.

[0021] like Figure 3 As shown, the control component includes a movable hole 16 opened on the cross bar 5 and a pressing block 10 slidably set in the movable hole 16. The movable hole 16 is communicated with the hollow chamber inside the cross bar 5. Fixed blocks 17 are fixed at both ends of the pressing block 10. A connecting rod 18 is provided between the fixed block 17 and the limiting column 15. The two ends of the connecting rod 18 are movably connected to the fixed block 17 and the limiting column 15 respectively.

[0022] like Figure 3 As shown, hold the pressing block 10 with your hand and move the pressing block 10 toward the direction close to the cross bar 5. The movement of the pressing block 10 will drive the fixed block 17 to move together, and then under the action of the connecting rod 18, drive the limit column 15 to move. The limiting mechanism includes a mounting tube 6 fixed in the lifting rod 4, a limiting block 7 slidably set in the mounting tube 6 and a movable groove 8 opened on the limiting block 7. One end of the movable groove 8 is provided with a first inclined surface 9, an upper through hole and a lower through hole are provided on the mounting tube 6, and a telescopic spring 12 is provided in the mounting tube 6.

[0023] like Figure 3As shown, a movable block 13 is provided in the movable groove 8, and a second inclined surface 14 is provided on the movable block 13, and the second inclined surface 14 is in contact with the first inclined surface 9. The upper and lower ends of the movable block 13 are fixed with limit columns 15. When the connecting rod 18 moves in the direction close to the cross bar 5, the limit column 15 will be driven to move upward. A plurality of limit holes 19 are provided on the movable rod 3. The limit block 7 partially passes through the limit hole 19 under the action of the telescopic spring 12 and is exposed on the outside of the movable rod 3. When the limit column 15 moves upward, it will drive the movable block 13 to move upward together. With the cooperation of the first inclined surface 9 and the second inclined surface 14, the movable block 13 will push the limit block 7 to move, so that The exposed part of the limit block 7 re-enters the installation tube 6, thereby releasing the fixed state between the movable rod 3 and the lifting rod 4, and making the movable rod 3 and the lifting rod 4 in a sliding state. At this time, the operator only needs to lift or press the cross bar 5 to achieve the height adjustment of the cross bar 5 in the vertical state. After the height adjustment is completed, release the grip on the pressing block 10, and the limit block 7 will move in the direction away from the spring under the elastic action of the telescopic spring 12, and then part of the limit block 7 will pass through the limit hole 19 again and be exposed, thereby achieving the fixation between the movable rod 3 and the lifting rod 4 again, and the height adjustment of the cross bar 5 in the vertical state is completed at this time.

[0024] like Figure 3 As shown, during the movement of the limit block 7, and with the cooperation of the first inclined surface 9 and the second inclined surface 14, the movable block 13 moves downward. Not only that, after the extrusion block is released, the limit column 15 and the movable block 13 will also return to their original positions under the action of their own gravity. The limit columns 15 located at the upper and lower ends of the movable block 13 partially pass through the upper through hole and the lower through hole respectively, and slide with the upper through hole and the lower through hole respectively. Through the limiting cooperation between the limit column 15 and the upper through hole and the lower through hole, the moving direction of the movable block 13 is guaranteed, and the movable block 13 can give the limit block 7 sufficient thrust when moving, ensuring that the exposed part of the limit block 7 can smoothly enter the installation tube 6.

[0025] like Figure 3 As shown, a rubber pad 20 is provided on the pressing block 10. The rubber pad 20 can enhance the friction between the hand and the pressing block 10 and also provide a certain comfort.
