A switch is located on the bed frame 1 near the patient's hand, and a controller is located at the bottom of the hip rest 3. The controller is electrically connected to the first drive mechanism 6, the second drive mechanism 7, and the switch. In this application, the switch has two buttons, one for controlling the first drive mechanism 6 and the other for controlling the second drive mechanism 7.

[0030] When in use, when the patient needs to adjust the back pad 2 or leg pad 4, they can directly press the corresponding button on the switch. The controller sends an electrical signal to the corresponding first drive mechanism 6 or second drive mechanism 7 to achieve posture control of the back pad 2 or leg pad 4. The adjustment process is entirely controlled by the patient according to their actual feeling, resulting in high adjustment satisfaction, improved patient comfort, and reduced workload for patients' families or medical staff. It is also convenient to use.

[0031] Furthermore, refer to Figure 2 The backrest 2 and leg pads 4 are equipped with cushioning elements 21 at their ends away from the hip pads 3. Corresponding limiting plates 11 are provided on the bed frame 1 for each cushioning element 21. When the backrest 2 and leg pads 4 are in a horizontal position, the cushioning elements 21 abut against the upper surface of the limiting plates 11. The cushioning elements 21 use buffer springs, which have good elasticity and energy absorption effects, reducing the impact force between the backrest 2 and leg pads 4 and the limiting plates 11, thus improving safety. The limiting plates 11 can be made of metal, making them sturdy and durable, ensuring they do not deform over long-term use.

[0032] Exemplary, the first driving mechanism 6 comprises a first connecting rod 61, a first screw rod 62, a first sliding block 63 and a power assembly 64, the first screw rod 62 is rotationally connected to the bed frame 1 along the length direction of the bed frame 1, the first sliding block 63 is sleeved on the first screw rod 62 along the length direction of the first screw rod 62 and is threadedly connected with the first screw rod 62, one end of the first connecting rod 61 is rotationally connected with the first sliding block 63, the other end of the first connecting rod 61 is rotationally connected with the back pad 2, and the rotation axis of the first connecting rod 61 is parallel to the rotation axis of the back pad 2.

[0033] When it is needed to adjust the angle of the back pad 2, the controller controls the power assembly 64 to drive the first screw rod 62 to rotate, so that the first sliding block 63 has a tendency to rotate with the first screw rod 62, and since the first sliding block 63 is connected with the first connecting rod and cannot rotate, the first sliding block 63 slides along the length direction of the first screw rod 62, and the sliding of the first sliding block 63 is transmitted to the back pad 2 through the first connecting rod 61, so that the back pad 2 rotates around the width direction of the bed frame 1, thereby realizing the adjustment of the angle of the back pad 2. Similarly, when it is needed to adjust the angle of the leg pad 4, the controller controls the power assembly 64 to drive the second screw rod 72 to rotate. During the rotation driving process of the back pad 2 and the leg pad 4, the controller can accurately control the movement of the back pad 2 and the leg pad 4 through the electrical connection with the power assembly 64, so as to ensure that the patient can obtain the best comfort during use. And through the arrangement of the screw rod and the sliding block, the rotation of the back pad 2 and the leg pad 4 is more stable and reliable, and the use is convenient.

[0034] Further, the first screw rod 62 and the second screw rod 72 can be made of stainless steel, which has good corrosion resistance and wear resistance, and ensures the stability under long-time use.

The butt joint component is arranged on the rotating shaft of the double-head motor 642, and is used for coaxial connection with the first screw rod 62 or the second screw rod 72.

[0036] When it is needed to adjust the angle of the back pad 2, the controller controls the movable end of the electric push rod to be in the retracted state, the rotating shaft of the double-head motor 642 on the sliding base 641 is close to one end of the first screw rod 62, and is connected with the first screw rod 62 under the action of the butt joint component on the first screw rod 62, so that the first screw rod 62 can rotate together with the rotating shaft of the double-head motor 642. At this time, starting the double-head motor 642 can drive the first screw rod 62 to rotate, and the functional requirement of the power assembly 64 driving the first screw rod 62 to rotate is realized. When it is needed to adjust the angle of the leg pad 4, the controller controls the movable end of the electric push rod to be in the elongated state, the rotating shaft of the double-head motor 642 on the sliding base 641 is close to one end of the second screw rod 72, and is connected with the second screw rod 72 under the action of the butt joint component on the second screw rod 72, so that the second screw rod 72 can rotate together with the rotating shaft of the double-head motor 642. At this time, starting the double-head motor 642 can drive the second screw rod 72 to rotate, and the functional requirement of the power assembly 64 driving the second screw rod 72 to rotate is realized.

[0037] Referring to Figure 1The docking component includes positioning posts 644 respectively arranged on the end faces of the rotating shafts of the double-head motor 642, two positioning posts 644 are arranged on the rotating shafts of the same side of the double-head motor 642, and the two positioning posts 644 are symmetrically arranged around the axis of the rotating shaft of the double-head motor 642, and the positioning post 644 is parallel to the rotating shaft of the double-head motor 642. The rotating block 645 is fixed on the end face of the first lead screw 62 and the second lead screw 72 close to the sliding seat 641, the length direction of the rotating block 645 is arranged along the radial direction of the first lead screw 62, and the rotating block 645 is used for clamping between the two positioning posts 644. When the sliding seat 641 moves to a specified position, the positioning post 644 is inserted into the gap between the rotating blocks 645, and the rotating block 645 rotates with the rotating shaft of the double-head motor 642 to drive the positioning post 644 to rotate, so that the coaxial connection of the rotating shaft of the double-head motor 642 and the first lead screw 62 or the second lead screw 72 is realized, and the docking component is simple and practical in structure. In addition, the end of the positioning post 644 away from the double-head motor 642 is provided with a round corner, and the end of the rotating block 645 close to the positioning post 644 is provided with a round corner, and the round corner design helps to reduce the collision and wear in the docking process, and improves the smoothness and reliability of the docking.

[0038] Further, the top four corners of the bed frame 1 are vertically mounted with stand rods 12, and adjacent two stand rods 12 are connected through a cross rod 13, and a plurality of hooks 14 are arranged on the cross rod 13. The structural design of the stand rod 12 and the cross rod 13 increases the stability of the bed frame 1, preventing accidents from occurring during use. The hooks 14 can be used to hang infusion bottles, traction equipment or other medical equipment, facilitating the operation of medical staff.

[0039] The implementation principle of the ABS bed head orthopedic traction bed is: when the angle of the back pad 2 needs to be adjusted, the patient can directly press the button on the switch for controlling the first driving mechanism 6 to send an electrical signal to the controller, and under the action of the controller, the movable end of the electric push rod is retracted. At this time, the positioning post 644 on the rotating shaft of the double-head motor 642 on the sliding seat 641 is clamped with the rotating block 645 on the first lead screw 62, and then the controller controls the double-head motor 642 to start, and the rotating shaft of the double-head motor 642 rotates to drive the first lead screw 62 to rotate, and then drives the first connecting rod 61 to slide along the length direction of the first lead screw 62, thereby driving the back pad 2 to rotate for angle adjustment. Similarly, when the angle of the leg pad 4 needs to be adjusted, the patient only needs to press the button on the switch for controlling the first driving mechanism 6. The whole adjustment process is completely controlled by the patient according to the actual feeling, the adjustment satisfaction is high, the patient comfort is improved, and the working strength of the patient's family members or medical staff is reduced, and the use is convenient.
