DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figure 1 - Figure 6 As shown, an obstetric care device with an adjustable armrest device comprises:

[0031] A bed frame 1, wherein a support leg 2 is provided at the bottom of the bed frame 1, a fixed bed board 3 is fixedly connected to the bed frame 1, and the fixed bed board 3 is hingedly connected to a movable bed board 4 that rotates upward;

[0032] An adjusting component, which is arranged at the lower part of the bed frame 1 and is used to adjust the rotation angle of the movable bed board 4;

[0033] A slide rail 9, wherein the slide rail 9 is arranged on the bed frame 1, and a mounting shell 10 with a positioning component arranged inside is slidably connected to the slide rail 9, and a plurality of positioning holes 91 for the positioning component to be inserted are opened on the slide rail 9;

[0034] The mounting tube 11 is fixedly mounted on the mounting shell 10, and an armrest 13 is provided at the end of the mounting tube 11, a rigid hose 26 is fixedly connected between the mounting tube 11 and the armrest 13, a plurality of balls 24 for triggering the positioning assembly are provided inside the mounting tube 11, the rigid hose 26 and the armrest 13, and a handle 25 for pushing the balls 24 is slidably inserted at the end of the armrest 13.

[0035] As can be seen from the above, when the user gets up from the bed, he can grab the armrest 13 for leverage. Due to the difference in arm span between people, the mounting shell 10 and the armrest 13 need to be adjusted to different positions. When adjusting the position of the armrest 13, the handle 25 can be pressed to drive the ball 24 to move, and the ball 24 triggers the positioning assembly, and then the mounting shell 10 is driven by the armrest 13 to move inside the slide rail 9 until the armrest 13 moves to the appropriate position, and the handle 25 is released. The positioning assembly cooperates with the positioning hole 91 to limit the movement of the mounting shell 10. At this time, the user can easily grab the armrest 13 for leverage, and the armrest 13 and the mounting tube 11 will not hinder the user's actions.

[0036] See also Figure 3 - Figure 6 As shown, the positioning assembly includes a positioning rod 17 slidably inserted on the mounting shell 10, a pull rod 18 hinged on the positioning rod 17 and a side pull assembly fixedly mounted on the inner wall of the mounting shell 10, the end of the positioning rod 17 extending out of the mounting shell 10 can be inserted into the positioning hole 91, the mounting cylinder 11 is slidably connected to a pressure rod 22 extending to the inside of the mounting shell 10, the upper end of the pressure rod 22 abuts against the ball 24, and the lower end of the pressure rod 22 is fixedly connected to a pressure block 23 for pushing the side pull assembly to move laterally.

[0037] When there is no external force, the side-pull assembly stops in place. At this time, the pull rod 18 is close to a vertical state, and the positioning rod 17 is extended out of the mounting shell 10 by the action of the pull rod 18. At this time, the positioning rod 17 is inserted into the positioning hole 91, and the mounting shell 10 cannot move. When the user drives the ball 24 to move by pressing the handle 25, the ball 24 will move downward to push the pressure rod 22. As the pressure rod 22 moves downward, the pressure rod 22 drives the pressure block 23 to move downward, and the downward pressure block 24 pushes the side-pull assembly to move sideways. The side-pull assembly drives the pull rod 18 to rotate tilted, so that the pull rod 18 gradually changes from a nearly vertical position to a nearly horizontal position. The rotating pull rod 18 will drive the positioning rod 17 to move upward, so that the positioning rod 17 disengages from the positioning hole 91. At this time, the mounting shell 10 loses the limit of the positioning rod 17, and the mounting shell 10 can slide freely inside the slide rail 9.

[0038] In order to ensure that the positioning rod 17 is evenly stressed and can slide up and down smoothly, one positioning rod 17 is hinged to two pull rods 18, and each pull rod 18 is equipped with a set of side pull components.

[0039] See also Figure 5 - Figure 6 As shown, the side pull assembly includes a slide bar 19 fixedly mounted inside the mounting shell 10, and a block 20 abutting against the pressure block 23 is slidably connected to the slide bar 19, and the pull rod 18 is hinged with the block 20, and the contact surfaces of the pressure block 23 and the block 20 are inclined, and a spring 21 abutting against the block 20 is sleeved on the slide bar 19, and the spring 21 applies a pushing force to the block 20, so that the block 20 is in the middle position of the mounting shell 10, and the pull rod 18 is close to a vertical state. When the pressure block 23 is forced to move downward, the pressure block 23 pushes to both sides. The stop block 20, the movable stop block 20 slides on the slide rod 19 and compresses the spring 21, the sliding stop block 20 drives the pull rod 18 to rotate, so that the pull rod 18 gradually moves toward the horizontal position, and the rotating pull rod 18 drives the positioning rod 17 to move upward, when the handle 25 is unstressed, the compressed spring 21 is reset to push the stop block 20 to move, the displaced stop block 20 pushes the pressure block 23 upward, and at the same time drives the pull rod 18 to rotate so that the positioning rod 17 extends out of the mounting shell 10 again, and the positioning rod 17 extending out of the mounting shell 10 will be inserted into the positioning hole 91, thereby limiting the displacement of the mounting shell 10 again.

[0040] The end of the mounting tube 11 is fixedly connected to a first connecting block 12, the end of the handrail 13 is fixedly connected to a second connecting block 14 hinged to the first connecting block 12, a plurality of through holes 15 are provided on the second connecting block 14, the first connecting block 12 is threadedly connected to a positioning bolt 16 inserted into the through hole 15, the handrail 13 can be rotated to change the angle between the handrail 13 and the mounting tube 11, and the user can flexibly adjust it according to the use requirements. When the angle between the handrail 13 and the mounting tube 11 is adjusted, the mutual rotation between the first connecting block 12 and the second connecting block 14 can be limited by the positioning bolt 16 and the through hole 15 to prevent the handrail 13 and the mounting tube 11 from rotating again.

[0041] See also Figure 1 As shown, the adjustment assembly includes a lead screw 5 rotatably connected to the lower part of the bed frame 1, and the end of the lead screw 5 is fixedly connected to a crank 6 for shaking the lead screw 5, a slide cylinder 7 is threadedly sleeved on the lead screw 5, and a bracket 8 is hinged between the slide cylinder 7 and the movable bed board 4. When the user needs to adjust the inclination angle of the movable bed board 4, the crank 6 can be used to drive the lead screw 5 to rotate, and the rotating lead screw 5 drives the slide cylinder 7 to move axially, and then the slide cylinder 7 drives the bracket 8 to rotate, and the rotating bracket 8 will support the movable bed board 4.

[0042] See also Figure 6 As shown, the rigid hose 26 is a steel hose, and the inner diameter of the rigid hose 26 is one to three millimeters larger than the diameter of the ball 24. The ball 24 can roll freely on the inner wall of the rigid hose 26 without causing deformation of the diameter of the rigid hose 26.

[0043] The slide rail 9 is fixedly mounted on the bed frame 1 by bolts, so that the equipment provider can install the slide rail 9 at a suitable position of the side wall of the bed frame 1 to broaden the application range of the armrest 13 .
