DETAILED DESCRIPTION

[0025] 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.

[0026] The utility model provides a device for improving increased muscle tension of lower limbs, comprising a base 1 and a slide rail 2. A stretching structure is provided on the top of the slide rail 2. The stretching structure comprises a thigh support 3, a calf support 4, a foot support 6, a support frame 8 and a second traction box 16.

[0027] One end of the thigh support 3 is movably connected to a fixed wheel 20, which is fixedly connected to one end of the slide rail 2, and one end of the thigh support 3 is movably connected to the slide rail 2 through the fixed wheel 20; the other end of the thigh support 3 is movably connected to the calf support 4, and both sides of the other end of the calf support 4 are movably connected to movable wheels 15, and the movable wheels 15 are movably connected to the inner cavity of the slide rail 2. It can be seen from the above description that under the action of external force, the structure formed by the calf support 4 and the thigh support 3 can move in the direction of the slide rail 2, so that when the device is in use, the structure formed by the calf support 4 and the thigh support 3 can achieve stretching of the patient's legs and improve the patient's lower limb muscle tension.

[0028] The middle part of the other end of the calf support 4 is fixedly connected with a foot support 6, and the patient's feet can be placed on the foot support 6. The thigh support 3, the calf support 4 and the foot support 6 are all provided with a restraint belt 5, and the patient's legs and feet can be fixed on the device by the restraint belt 5.

[0029] The end of the slide rail 2 away from the fixed wheel 20 is fixedly connected to the support frame 8, and the end of the support frame 8 away from the slide rail 2 is provided with a second traction box 16, and the second traction box 16 is movably connected to the support frame 8 through a cross bar. Through the setting of the cross bar, the second traction box 16 can be limited so that the second traction box 16 can move in the vertical direction. The calf support 4 is connected to the second traction box 16 through a pull rope 7, and there are two pull ropes 7. The two sides of the end of the calf support 4 away from the thigh support 3 are movably connected with the pull rope 7. Through the setting of the pull rope 7, the second traction box 16 can pull the calf support 4 so that the calf support 4 can be close to the support frame 8.

[0030] The top of the support frame 8 is movably connected to a third pulley 9, the pull rope 7 is wound around the third pulley 9, and the pull rope 7 is in contact with the top of the third pulley.

[0031] A quantitative discharging box 10 is provided at the bottom end of the top of the side of the support frame 8 away from the slide rail 2, and the second traction box 16 is located between the two quantitative discharging boxes 10. A discharge pipe is provided in the middle of the bottom of the second traction box 16, and an electric ball valve is provided at one end of the discharge pipe.

[0032] From the above description, it can be known that when the quantitative discharge box 10 located above the second traction box 16 puts the granular material stored therein into the second traction box 16, the weight of the second traction box 16 increases, and the second traction box 16 can pull the calf support 4. When the granular material in the second traction box 16 is discharged into the inner cavity of another quantitative discharge box 10 through the discharge pipe, the weight of the second traction box 16 is reduced, and the traction on the calf support 4 can be released or the traction speed of the calf support 4 can be slowed down.

[0033] One end of the slide rail 2 close to the fixed wheel 20 is movably connected with a guide roller 17, and a draw rope 3 19 is wound around the guide roller 17. One end of the draw rope 3 19 is fixedly connected to the bottom of the end of the calf support 4 away from the thigh support 3, and the other end of the draw rope 3 19 is fixedly connected to a spring 2 18, and the other end of the spring 2 18 is fixedly connected to the slide rail 2, and the spring 2 18 and the calf support 4 are located on the same side of the guide roller 17. When the calf support 4 moves under the action of the second traction box 16, the spring 2 18 is in a stretched state, and when the traction force of the second traction box 16 on the calf support 4 is less than the traction force of the spring 2 18 on the calf support 4, the rebound force of the spring 2 18 pulls the draw rope 3 19, and the other end of the draw rope 3 19 pulls the calf support 4, so that the calf support 4 can be away from the support frame 8.

[0034] From the above description of the stretching structure, it can be known that the user can realize the reciprocating movement of the calf support 4 in the inner cavity of the slide rail 2 by adjusting the weight of the second traction box 16. During the movement, the calf support 4 can realize the forward and backward stretching of the lower limbs of the patient fixed on the device, improve the patient's lower limb muscle tension, and control the traction force and traction speed of the stretching structure on the patient according to the patient's condition, thereby improving the adaptability of the device.

[0035] The top of the base 1 is connected to the slide rail 2 through a rotating structure. Through the setting of the rotating structure, the operation of the rotating structure can cause the slide rail 2 to rotate, so that when the device is in use, the device can pull the patient from multiple angles, thereby improving the adaptability of the device.

[0036] The rotating structure includes a rotating shaft 21, which is fixedly connected to the bottom of one end of the slide rail 2 away from the support frame 8, and the rotating shaft 21 is movably connected to the base 1. The outer ring of the rotating shaft 21 is fixedly connected to a rotating handle 22, and the other end of the rotating handle 22 is movably connected to a connecting rod 1 23, and the other end of the connecting rod 1 23 is movably connected to a connecting rod 2 24. Through the arrangement of the connecting rod 1 23 and the connecting rod 2 24, the movement of the connecting rod 24 can push the rotating handle 22 to rotate through the connecting rod 1 23, and the rotating handle 22 drives the rotating shaft 21 fixedly connected thereto to rotate, and the rotating shaft 21 can drive the slide rail 2 fixedly connected thereto to rotate.

[0037] One end of the connecting rod 24 is fixedly connected to the base 1 through a spring 1 25 , and the other end of the connecting rod 24 is fixedly connected to a pull rope 11 . One end of the base 1 away from the slide rail 2 is fixedly connected to a support rod 12, and the top of the base 1 is movably connected to a first pulley, the first slide rail is located between the slide rail 2 and the support rod 12, the pull rope 11 contacts the bottom of the first pulley, the top of the support rod 12 is movably connected to the second pulley, the pull rope 11 contacts the top of the second pulley, and the support rod 12 is movably connected to a first traction box 13 at one end away from the slide rail 2, and the other end of the pull rope 11 is fixedly connected to the first traction box 13. When the first traction box 13 drives the pull rope 11 to move downward, the other end of the pull rope 11 drives the connecting rod 24 to move, and the movement of the connecting rod 24 allows the rotating handle 22 to rotate. When the first traction box 13 releases the traction of the pull rope 11, the rebound force of the spring 1 25 can push the connecting rod 24 to move in the opposite direction, so that the rotating handle 22 can be reset, and then the slide rail 2 can be reset.

[0038] The top and bottom ends of the support rod 12 are both clamped with a quantitative discharge box 14, the first traction box 13 is located between the two quantitative discharge boxes 14, a discharge pipe is provided in the middle of the bottom of the first traction box 13, and an electric ball valve is provided at one end of the discharge pipe. Through the arrangement of the discharge pipe and the electric ball valve, the granular material in the first traction box 13 can fall into the inner cavity of the quantitative discharge box 14 below it, and the quantitative discharge box 14 located above the first traction box 13 can put the granular material stored therein into the first traction box 13.

[0039] From the above description of the rotating structure, it can be seen that during use of the device, the rotation and resetting of the slide rail 2 can be achieved by changing the weight of the granular material in the first traction box 13, so that the device can achieve left and right traction of the patient's legs and change the traction direction.

[0040] During use of the device, the positions of the two quantitative discharging boxes 14 can be swapped, and the positions of the two quantitative discharging boxes 10 can be swapped. The quantitative discharging box 14 and the quantitative discharging box 2 10 are both prior art. In some embodiments of the present application, the structures of the quantitative discharging box 14 and the quantitative discharging box 2 10 are the same as the structure of the quantitative feeding device disclosed in the authorized patent with application number CN202023067613.7.

[0041] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0042] In summary: when the device for improving increased muscle tension in the lower limbs is used, the patient's thigh is fixed to the thigh support 3 through the restraint belt 5, the patient's calf is fixed to the calf support 4 through the restraint belt 5, and the patient's foot is fixed to the foot support 6 through the restraint belt 5. The medical staff adjusts the traction force and traction length of the second traction box 16 on the calf support 4 according to the patient's lower limb condition. The quantitative discharge box 2 10 located above the second traction box 16 discharges the corresponding granular material into the second traction box 16. The weight of the second traction box 16 increases, and the second traction box 16 can pull the calf through the pull rope 2 7 under the action of gravity. The bracket 4 is pulled, and the calf bracket 4 gradually approaches the support frame 8. At this time, the stretching structure realizes the stretching of the patient's lower limbs. When the second traction box 16 moves to the lowest position, the electric ball valve below the second traction box 16 works, and the granular material in the second traction box 16 is discharged into another second traction box 16 through the discharge pipe, and the traction of the second traction box 16 on the calf bracket 4 is released. The rebound force of the spring two 18 pulls the pull rope three 19, and the other end of the pull rope three 19 pulls the calf bracket 4. The calf bracket 4 is moved away from the support frame 8 under the action of the pull rope three 19, and the calf bracket 4 can be reset, which is convenient for the device to perform the next stretching and traction on the patient's lower limbs.

[0043] When the patient's legs need to be pulled left and right, the rotating structure works, and an appropriate amount of granular material in the quantitative discharge box 14 is discharged into the first traction box 13. The first traction box 13 drives the connecting rod 24 to move through the pull rope 11, and the connecting rod 24 drives the rotating handle 22 to rotate through the connecting rod 23. The rotating handle 22 drives the slide rail 2 to rotate through the rotating shaft 21, which can realize the outward traction of the patient's legs. When the material in the first traction box 13 is discharged into the inner cavity of the quantitative discharge box 14 below it, the rebound force of the spring 1 25 pushes the connecting rod 24 to move in the opposite direction. The reverse movement of the connecting rod 24 causes the slide rail 2 to rotate in the opposite direction, realizing the resetting of the patient's legs. The coordinated use of the first traction box 13 and the spring 1 25 enables the device to realize the left and right traction of the patient's legs.
