DETAILED DESCRIPTION

[0020] 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 in 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.

[0021] See also Figure 1 The utility model provides a technical solution: a length-adjustable obstetric bed, comprising: a bed frame 1 and armrests 4, a support base 2 is installed at the bottom of the bed frame 1, a mattress 3 is installed on the top of the support base 2, and the armrests 4 are installed on both sides of the bed frame 1;

[0022] A driving motor 5 is installed inside the bed frame 1, and the output end of the driving motor 5 is connected to a screw rod 6 through a coupling. A screw sleeve 7 is sleeved on the outer side of the screw rod 6, and first connecting rods 8 are installed on both sides of the screw sleeve 7. The end of the first connecting rod 8 away from the screw sleeve 7 is connected to a support frame 9, and a cylinder 10 is installed on the top of the support frame 9. A connecting frame 11 is installed at one end of the cylinder 10. Slide blocks 12 are installed at both ends of the connecting frame 11 through a fixed frame, and a track 13 is installed at the bottom of the slider 12. The top of the slider 12 is connected to a connecting rod 14 through a rotating shaft, and the top of the connecting rod 14 is connected to a support pad 15 through a rotating shaft. A baffle 16 is installed on the top of the support frame 9, and the baffle 16 and the support frame 9 are an integrated structure. The track 13 is installed on the inner wall of the support frame 9

[0023] During specific implementation, when the length of the obstetric bed with adjustable length needs to be adjusted, the driving motor 5 can be started, and the driving motor 5 will drive the screw rod 6 connected at one end to rotate. A screw sleeve 7 is sleeved on the outer side of the screw rod 6. Both sides of the screw sleeve 7 are connected to the inner wall of the support frame 9 through the first connecting rod 8, and the support frame 9 is slidably connected to the groove of the bed frame 1. Therefore, when the screw rod 6 rotates, the support frame 9 will be driven to retract along the groove of the bed frame 1 through the cooperation of the screw sleeve 7 and the first connecting rod 8. After the support frame 9 is pushed out of the groove of the bed frame 1, the cylinder 10 can be started to extend the cylinder 10. Since one end of the cylinder 10 is connected to the connecting frame 11, and the connecting frame 11 is connected to the slider 12 through the fixed frame, when the cylinder 10 is extended, it will push the slider 12 to slide along the track 13 on the inner wall of the support frame 9, and the slider 12 will drive the support frame 9 through the connecting rod 14 when sliding. The support pad 15 moves in the direction of the baffle 16. When the support pad 15 moves to one side of the baffle 16, the support pad 15 cannot move forward, and the bottom slider 12 will continue to slide along the track 13 under the action of the cylinder 10. Since the support pad 15 cannot move, the two ends of the connecting rod 14 at the bottom of the support pad 15 are connected between the support pad 15 and the slider 12 through a rotating shaft, and a blocking block is also provided on the top of the slider 12. Through the blocking block, the connecting rod 14 will not rotate in the direction of the cylinder during rotation. Therefore, when the slider 12 moves, it will drive the connecting rod 14 to rotate upward through the rotating shaft. The upward rotation of the connecting rod 14 will push the support pad 15 to move upward, so that the support pad 15 and the mattress 3 are flush with each other. At this time, it will not affect the normal use needs of the user, and the entire obstetric bed has the function of adjusting the length. Conversely, the above steps can be reversed to shrink the support pad 15 into the groove of the bed frame 1.

[0024] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 It can be seen that when in use, according to the needs of use, the support pad 15 can be quickly pushed out of the groove of the bed frame 1 by driving the motor 5, and the support pad 15 can be pushed upward. The patient can be supported by the support pad 15, thereby meeting the different usage needs of the user, so that the entire obstetric bed has the function of adjusting the length.

[0025] A mounting frame 17 is installed on both sides of the bed frame 1, and a movable frame 18 is connected through one side of the mounting frame 17. A leg support 19 is installed on the top of the movable frame 18, and a foot support 20 is installed on one side of the leg support 19 through a bracket. A second connecting rod 21 is connected to one end of the movable frame 18, and a threaded sleeve 22 is installed at the bottom of the second connecting rod 21. A bidirectional screw rod 23 is connected through the middle of the threaded sleeve 22, and a bevel gear set 24 is connected in the middle of the bidirectional screw rod 23. The bottom of the bevel gear set 24 is connected to a transmission motor 25 through a transmission shaft, and the transmission motor 25 is installed at the bottom of the mounting frame 17 through a housing.

[0026] In specific implementation, when the length-adjustable obstetric bed needs to adjust the distance between the leg rests 19 and the foot rests 20 on both sides of the bed frame 1, the transmission motor 25 can be started, and the transmission motor 25 will drive the bevel gear set 24 to rotate through the transmission shaft. The bevel gear set 24 is connected by two mutually meshing bevel gears, one of which is connected to the transmission shaft of the transmission motor 25, and the other is connected to the bidirectional screw 23. With the cooperation of the bevel gear set 24, the bidirectional screw 23 is rotated, and both ends of the bidirectional screw 23 are connected to the bottom of the bed frame 1 through a fixed frame and a bearing, thereby ensuring that the bidirectional screw 23 is more stable when rotating. A threaded sleeve 22 is sleeved on the outer side of the bidirectional screw 23, and the threaded sleeve 22 A second connecting rod 21 is connected to the top of the frame 17, and the second connecting rod 21 passes through the mounting frame 17 and is connected to the movable frame 18. Under the guiding effect of the mounting frame 17, the bidirectional screw 23 drives the movable frame 18 to move through the threaded sleeve 22 and the second connecting rod 21 when rotating, and the top of the movable frame 18 is connected to the leg rest 19, and at the same time, one side of the movable frame 18 is connected to the foot rest 20 through a bracket. At this time, the movement of the movable frame 18 can drive the foot rest 20 and the leg rest 19 to move, and under the action of the bidirectional screw 23, the two groups of foot rests 20 and leg rests 19 move closer to each other or away from each other, thereby facilitating the adjustment of the distance between the foot rest 20 and the leg rest 19 to meet the different usage requirements of users.

[0027] See also Figure 1 and Figure 3 It can be seen that when in use, the transmission motor 25 can be started according to the use requirements. The transmission motor 25 will drive the bidirectional screw 23 to rotate through the bevel gear set 24, and cooperate with the threaded sleeve 22 and the second connecting rod 21 to drive the movable frame 18 to move, thereby facilitating the adjustment of the position of the leg rest 19 and the foot rest 20, ensuring that the patient can lie more comfortably on the obstetric bed.

[0028] To sum up: when the adjustable-length obstetric bed is in use, the support base 2 can be placed in a stable position, and then the pregnant woman can lie flat on the mattress 3, and the stability of the entire mattress 3 is ensured by the bed frame 1, and the feet can be placed on the leg rest 19 and the foot rest 20 as needed, and then the delivery operation can be performed. This is the use feature of the adjustable-length obstetric bed.
