[0059] The tensioning assembly includes:

[0060] Two L-shaped plates 2, the two L-shaped plates 2 are respectively fixed on the top and bottom of the support plate 1, and the side wall of each L-shaped plate 2 is rotatably provided with a guide assembly;

[0061] A rotating shaft 19, the rotating shaft 19 is rotatably arranged between the two L-shaped plates 2;

[0062] The transmission seat 5 is fixedly sleeved on the rotating shaft 19. The top of the transmission seat 5 is provided with a plurality of fixing holes distributed at equal distances, and a clutch assembly is arranged in each fixing hole;

[0063] Two winding reels 4 are rotatably sleeved on the rotating shaft 19. The side walls of the two winding reels 4 close to the transmission seat 5 are provided with multiple circular holes 20, and the circular holes 20 correspond to the clutch components one by one. The clutch components are used to cooperate with the circular holes 20 to drive the winding reels 4 to rotate.

[0064] When the clutch assembly is not working, the tension of the traction rope can be adjusted by the free rotation of the winding disk 4. In addition, the tension of each traction rope can be made uniform by adjusting the guide assembly, thereby ensuring uniform force in all directions acting on the patient during the subsequent traction process to ensure the traction effect;

[0065] When the clutch assembly is working, the rotation of the transmission seat 5 can drive the winding disk 4 to rotate, thereby achieving the tensioning and traction of the traction rope, without the need for medical staff to perform adjustments.

[0066] Furthermore, the fixing assembly includes:

[0067] A fixing plate 7, the fixing plate 7 is fixed on the side wall of the support plate 1, and a first threaded hole is opened on the side wall of the fixing plate 7;

[0068] The screw rod 8 is connected to the first threaded hole through a thread, a first knob is fixed to one end of the screw rod 8, and the other end of the screw rod 8 is rotatably connected to the extrusion plate 9.

[0069] When installing the device, place the raised part of the bed between the support plate 1 and the extrusion plate 9, then rotate the first knob to drive the screw 8 to rotate, and cooperate with the first threaded hole to make the extrusion plate 9 close to the support plate 1, thereby achieving the fixation of the device and the bed.

[0070] Further, the clutch assembly includes:

[0071] The cylinder 24 is fixed in the mounting hole;

[0072] Two second pistons 28, both of which are slidably disposed in the cylinder 24;

[0073] A spring 29, the spring 29 is fixed between the two second pistons 28;

[0074] Two transmission rods 25 are fixed to the two second pistons 28 respectively, and the two transmission rods 25 pass through the top and the bottom of the cylinder 24 respectively, and the transmission rods 25 are adapted to the round hole 20 .

[0075] Furthermore, the tensioning assembly also includes:

[0076] An annular tube 17, on which a plurality of connecting tubes are fixed, and the plurality of connecting tubes are connected to the plurality of cylinders 24 in one-to-one relationship;

[0077] The solenoid valve 18 is disposed through the annular tube 17 .

[0078] Furthermore, an annular groove 22 is formed on the side wall of the winding disc 4 close to the transmission seat 5 , and a plurality of rubber sheets 23 distributed at equal distances are fixed on the inner wall of the annular groove 22 .

[0079] In an emergency, the switch of the solenoid valve 18 can be turned on, and the cylinder 24 can be connected to the outside world through the connecting pipe, the annular tube 17, and the solenoid valve 18. Under the action of the spring 29, the transmission rod 25 is driven down, and because the tension of the spring 29 is limited, the top of the transmission rod 25 and the rubber sheet 23 are in conflict. Under the friction between the transmission rod 25 and the rubber sheet 23, the rapid rotation of the winding disk 4 is avoided, thereby avoiding the patient's injury caused by the instantaneous loosening of the traction rope.

[0080] Furthermore, the tensioning assembly also includes:

[0081] The sleeve 21 is connected to the annular tube 17, and a second threaded hole is formed on the top of the sleeve 21;

[0082] A first piston 27, the first piston 27 is slidably disposed in the sleeve 21;

[0083] The screw rod 26 is rotatably arranged on the top of the first piston 27 , the screw rod 26 passes through the second threaded hole, and a second knob is fixed on the top of the screw rod 26 .

[0084] By turning the second knob and cooperating with the second threaded hole, the screw rod 26 is gradually moved into the sleeve 21. In the process, the first piston 27 is driven to descend, and the gas in the sleeve 21 is injected into each cylinder 24 through the annular tube 17 and the connecting tube. Through the action of the two second pistons 28 in the cylinder 24, the transmission rod 25 can pass through the circular hole 20 on the winding drum 4, thereby realizing the fixation between the winding drum 4 and the transmission seat 5.

[0085] Further, the guide component includes:

[0086] An adjusting plate 6, the adjusting plate 6 is rotatably arranged on the side wall of the L-shaped plate 2;

[0087] A rod body 13, the rod body 13 is fixed to the end of the adjustment plate 6, and a ball head 14 is fixed to the end of the rod body 13;

[0088] A seat body 15, a spherical groove is formed on the side wall of the seat body 15, and a ball head 14 is rotatably arranged in the spherical groove;

[0089] The guide ring 16 is fixed on the seat body 15 .

[0090] Furthermore, the guide component also includes:

[0091] An electric push rod 12, the end and telescopic end of the electric push rod 12 are both provided with a connecting block 11;

[0092] There are two connecting seats 10, one of which is fixed on the top of the support plate 1, and the other is fixed on the bottom of the adjustment plate 6, and the two connecting blocks 11 are rotatably connected to the two connecting seats 10 one by one.

[0093] When the electric push rod 12 is turned on, the adjustment plate 6 is rotated by the rotation between the two sets of connecting seats 10 and the connecting block 11 when the electric push rod 12 is working, so that the traction rope can be further tightened. Through the operation of the electric push rod 12, the tensioning degree of each traction rope is made uniform. In this process, the multi-angle rotation between the ball head 14 and the seat body 15 is used to ensure that the bending angle of the traction rope is reduced, thereby avoiding excessive resistance between the traction rope and the guide ring 16, so as to avoid the traction rope from breaking when the tension is too large.

[0094] Furthermore, motors 3 are fixed to the tops of the two upper L-shaped plates 2 , and the output shafts of the two motors 3 are fixed to the two rotating shafts 19 respectively.

[0095] The specific working method is: when performing traction stretching, first prepare two sets of the device and install them at the head and foot of the bed respectively, then use the headgear to fix the lower part of the patient, and pass the four traction ropes on the headgear through the four guide rings 16 at the head of the bed respectively, fix the waist fixing belt around the patient's waist, pass the four traction ropes of the waist fixing belt through the four guide rings 16 at the foot of the bed respectively, and fix the traction rope to the nearest winding drum 4, and then adjust the work;

[0096] When installing the device, the raised part of the bed is placed between the support plate 1 and the extrusion plate 9, and then the screw 8 is rotated by rotating the first knob, and the extrusion plate 9 is made close to the support plate 1 in cooperation with the first threaded hole, thereby achieving the fixation of the device and the bed;

[0097] When making adjustments, first ensure that each transmission rod 25 is in the cylinder 24 so that the winding disk 4 can rotate freely. The rotation of the winding disk 4 is used to tighten the traction rope. When all the traction ropes are tightened, the second knob is turned to cooperate with the second threaded hole to gradually move the screw rod 26 into the sleeve 21. In this process, the first piston 27 is driven to descend, and the gas in the sleeve 21 is injected into each cylinder 24 through the annular tube 17 and the connecting tube. Through the action of the two second pistons 28 in the cylinder 24, the transmission rod 25 can pass through the circular hole 20 on the winding disk 4, thereby achieving the fixation between the winding disk 4 and the transmission seat 5.

[0098] Since the lengths of the traction ropes are different, after the rotation of the winding disk 4 is restricted, the switch of the corresponding electric push rod 12 is turned on according to the situation of the traction rope. When the electric push rod 12 is working, the adjustment plate 6 is rotated by the rotation between the two sets of connecting seats 10 and the connecting block 11, so that the traction rope can be further tightened. Through the operation of the electric push rod 12, the tension of each traction rope is unified. In this process, the multi-angle rotation between the ball head 14 and the seat body 15 is used to ensure that the bending angle of the traction rope is reduced, thereby avoiding excessive resistance between the traction rope and the guide ring 16, so as to avoid the traction rope from breaking when the tension is too large;

[0099] When performing traction work, the switch of the motor 3 is turned on, and the motor 3 drives the rotating shaft 19 to rotate slowly. During the rotation of the rotating shaft 19, the transmission seat 5 is driven to rotate, and then the winding disk 4 is driven to rotate through the cooperation of the cylinder 24, the transmission rod 25 and the round hole 20, thereby realizing traction of the waist at four angles and traction of the head at four angles, so as to achieve uniform force during the traction process. When the tension reaches a certain degree, the speed of the motor 3 is changed, and the traction rope is continuously wound at an extremely slow speed to achieve continuous increase in traction strength, thereby eliminating the need for medical staff to frequently adjust the work;

[0100] During the traction process, when daily activities are needed, the second knob can be rotated in the opposite direction to drive the first piston 27 to rise, so that each transmission rod 25 can be retracted into the cylinder 24 to achieve the re-rotation of the winding drum 4, thereby facilitating the release of the headgear and the waist fixing belt. When the tension is too large, if the patient cannot bear it, etc., the switch of the solenoid valve 18 can be turned on, and the cylinder 24 can be connected to the outside world through the connecting pipe, the annular pipe 17, and the solenoid valve 18. Under the action of the spring 29, the transmission rod 25 is driven down, and because the pulling force of the spring 29 is limited, the top of the transmission rod 25 is in conflict with the rubber sheet 23. Under the friction between the transmission rod 25 and the rubber sheet 23, the rapid rotation of the winding drum 4 is avoided, thereby avoiding the patient's injury caused by the instantaneous loosening of the traction rope.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
