Description

Technical Field

[0001] The present invention relates to the technical field of motion measurement, and particularly to an ankle pump motion measuring instrument. Background Art

[0002] Ankle pump exercise mobilizes the function of the calf muscle pump through the movement of the ankle joint, promotes blood circulation and lymphatic return in the lower extremities through the contraction and relaxation of the muscles, and prevents deep vein thrombosis in the lower extremities. It includes two movements: flexion and extension of the ankle joint and circumduction. The patient lies flat on the bed, the thigh is extended, the lower extremities are relaxed, first hook the toes upward as much as possible, keep the toes facing oneself for about 5 seconds; then point the toes downward and do dorsiflexion for about 5 seconds; after a little relaxation, it can be done again. Finally, with the ankle joint as the center, make a 360° circumduction of the ankle joint.

[0003] In the prior art, in order to ensure the effect of ankle pump exercise, a measuring instrument is usually used to measure ankle pump exercise, such as measuring the flexion and extension angle of the ankle joint, or measuring the number of times the ankle joint can reach within a specified flexion and extension angle. However, in the prior art, for different patients, the sizes of the feet are different, and conventional measuring instruments are difficult to apply to different populations. Moreover, the flexion and extension movements of the ankle joint need to be carried out separately, and it is inconvenient to adjust the measuring position. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide an ankle pump motion measuring instrument to solve the problems raised in the above background art. The structure of the present invention is novel. The flexion and extension movements of the ankle joint can be realized through two sets of winding components. The measuring component can be alternately connected with the two sets of winding components to separately measure different flexion and extension movements, and the adjustment and replacement are relatively convenient. The shape and size of the device can be adjusted according to the size of the user's foot, and it is suitable for different populations.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: An ankle pump motion measuring instrument includes a bottom plate. There are two groups of the bottom plates. A middle plate is slidably installed between the two groups of bottom plates. Two telescopic columns are symmetrically fixed on the top of the bottom plate, and the top of the extended end of the telescopic column is fixed with a top plate. A winding component is installed on the bottom plate. The winding component includes a winding seat. There are two winding seats symmetrically arranged on the top plate. A connecting rope is wound inside the winding seats on the same straight line of the two top plates. A measuring component is arranged on the outside of the top plate on one side of the middle plate. The measuring component includes an inner slide rail and an outer slide rail. The inner slide rail and the outer slide rail are fixed on the outside of the winding shaft, and both the inner slide rail and the outer slide rail are semi-circular. A connecting plate is slidably installed at the bottom of the outer slide rail and the inner slide rail, and contact buttons are fixed at both ends of the connecting plate. A counter is fixed on the outside of the connecting plate. A first limiting plate is fixed on the top of the bottom plate, and two second limiting plates are symmetrically and slidably installed on the top of the middle plate. A storage groove is opened at the bottom of the bottom plate, and both ends of the middle plate are slidably inserted into the storage groove.

[0006] Further, a bidirectional screw is rotatably installed on the top surface of the middle plate through a bearing. The bottom of the second limiting plate is threadedly sleeved on the surface of the bidirectional screw. A lifting screw is rotatably installed at the top of one end of the middle plate through a bearing, and a bidirectional telescopic plate is threadedly sleeved on the surface of the lifting screw. The two extended ends of the bidirectional telescopic plate are fixed to the top plate. <\\u

[0007] Further, a resisting plate is fixed at the front end of the first limiting plate. A sliding groove is opened on the top surface of the top plate, and two sliding seats are symmetrically and slidably installed inside the sliding groove. The sliding seat is fixedly connected to the bottom of the winding seat.

[0008] Further, the winding component further includes a fixing bolt. The fixing bolt is threadedly inserted on the outside of the sliding seat, and the fixing bolt is in pressing contact with the side surface of the top plate. The winding shaft inside the winding seat is rotatably installed through a torsion spring and a bearing. A connecting shaft fixedly connected to the winding shaft rotates out through the top of the winding seat.

[0009] Further, the measuring component further includes a sliding rod. The sliding rod is fixed on the outside of the top plate, and a sliding frame is slidably sleeved on the surface of the sliding rod. A turning knob is rotatably installed at the top of the sliding frame. The turning knob and the center of the connecting shaft are on the same vertical line. A connecting frame is fixed on one side of the turning knob, and the connecting frame is fixedly connected to the counter.

[0010] Further, an installation plate is arranged at the top of the connecting shaft, and a push rod is fixed on one side of the installation plate. The push rod moves between the inner slide rail and the outer slide rail. An angle scale is sleeved at the bottom of the connecting shaft, and the angle scale is fixedly connected to the top of the winding seat.

[0011] Further, a circular ring is sleeved on the middle surface of the connecting shaft, and a magnet block is fixed on one side of the circular ring between the inner sliding rail and the outer sliding rail. A metal layer is provided on the surface of the connecting plate, and the connecting plate can be magnetically adsorbed to the magnet block.

[0012] Further, locking bolts are threadedly inserted into the top of the mounting plate and the outer surface of the circular ring, and the locking bolts are in pressing contact with the top and side surfaces of the connecting shaft.

[0013] Further, a convex block is fixed on the top of the connecting plate, and the convex block is slidably clamped between the inner sliding rail and the outer sliding rail.

[0014] Further, a fixing frame is fixed at one end of the inner sliding rail and the outer sliding rail, and the bottom of the fixing frame is fixedly connected to the top of the winding base.

[0015] Advantages of the present invention:

[0016] 1. In the present invention, the connecting plate is inserted along one end of the inner sliding rail and the outer sliding rail. The convex block slides between the inner sliding rail and the outer sliding rail. When moving to the position of the magnet block, the connecting plate is magnetically adsorbed to the magnet block. Then, when the foot stretches forward, the front-end connecting rope is unwound. The connecting shaft drives the push rod to rotate until it reaches the position of the connecting plate and presses against the contact button on one side of the connecting plate, so that the counter counts once. When it is necessary to change to the foot flexion movement, the connecting plate is manually pushed to move and separated from the magnet block, and pulled out along the opening of the inner sliding rail and the outer sliding rail. During this process, when the connecting plate moves along the path of the inner sliding rail and the outer sliding rail, it maintains the connection with the sliding frame through the rotation of the connecting frame and the rotary knob. After completely moving out of the front-end winding base, the sliding frame slides along the sliding rod, and the counter is sent into the opening ends of the inner sliding rail and the outer sliding rail of the rear-end winding base until the connecting plate is adsorbed to the magnet block of the rear-end winding base for foot flexion training.

[0017] 2. In the present invention, the winding base can slide along the sliding rod through the sliding frame, and the position of the counter can be changed. It can be switched and adjusted according to the measurement of foot extension or flexion. According to the connection between the rotary knob and the connecting frame, it is convenient for the connecting plate to slide along the inner sliding rail and the outer sliding rail.

[0018] 3. In the present invention, the middle plate is pulled out from the storage groove to adjust the distance between the two first limiting plates. Then, the bidirectional screw is rotated to move the second limiting plate close to the inner surfaces of the two feet. The first limiting plate and the second limiting plate cooperate to limit the human foot. According to different lengths of human feet, the lifting screw is rotated, and the bidirectional telescopic plate moves along the surface of the lifting screw, driving the top plate and the telescopic column to expand, so that parts of the two connecting ropes are close to the two side surfaces of the front sole. Then, the position of the winding base is adjusted through the inside of the chute, so that the two connecting ropes can be adjusted according to the differences of different human foot soles at the rear end, making them contact the sole. After the adjustment is completed, it is locked by the fixing bolt.

[0019] 4. Compared with the prior art, the present invention can achieve the flexion and extension movement of the ankle joint through two sets of winding components. The measuring component can be alternately connected to the two sets of winding components to separately measure different flexion and extension movements, which is convenient for adjustment and replacement. The shape and size of the device can be adjusted according to the size of the user's foot, making it suitable for different groups of people to use. Brief Description of the Drawings

[0029] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0030] Please refer to Figures 1 to 8 , the present invention provides a technical solution: an ankle pump motion measuring instrument, including a bottom plate 1, there are two groups of the bottom plate 1, a middle plate 11 is slidably installed between the two groups of the bottom plate 1, two telescopic columns 12 are symmetrically fixed on the top of the bottom plate 1, and the top of the extended end of the telescopic column 12 is fixed with a top plate 13. A winding assembly 2 is installed on the bottom plate 1. The winding assembly 2 includes a winding seat 24. There are two winding seats 24 symmetrically arranged on the top plate 13. A connecting rope 25 is wound inside the winding seats 24 on the same straight line of the two top plates 13. A measuring assembly 3 is arranged outside the top plate 13 on one side of the middle plate 11. The measuring assembly 3 includes an inner slide rail 37 and an outer slide rail 36. The inner slide rail 37 and the outer slide rail 36 are fixed on the outside of the winding shaft, and both the inner slide rail 37 and the outer slide rail 36 are semi-circular. A connecting plate 315 is slidably installed at the bottom of the outer slide rail 36 and the inner slide rail 37, and contact buttons 317 are fixed at both ends of the connecting plate 315. A counter 35 is fixed on the outside of the connecting plate 315. A first limiting plate 16 is fixed on the top of the bottom plate 1, and two second limiting plates 19 are symmetrically and slidably installed on the top of the middle plate 11. A storage groove 110 is opened at the bottom of the bottom plate 1, and both ends of the middle plate 11 are slidably inserted into the storage groove 110. When using the device, the patient lies flat with both feet placed on the bottom plate 1. According to the distance between the patient's two feet, the foot length and the rear end of the forefoot, the device is adjusted so that the two connecting ropes 25 are in contact with the front and rear surfaces of the foot. Through the connection between the winding assembly 2 and the measuring assembly 3, the forward extension and backward flexion of the foot can be adjusted in groups, and the number of times of the forward extension and backward flexion angles that meet the requirements can be measured.

[0031] In this embodiment, a bidirectional screw 18 is rotatably mounted on the top surface of the middle plate 11 by means of a bearing. The bottom of the second limiting plate 19 is threadedly sleeved on the surface of the bidirectional screw 18. One end of the top of the middle plate 11 is rotatably mounted with a lifting screw 14 by means of a bearing, and a bidirectional telescopic plate 15 is threadedly sleeved on the surface of the lifting screw 14. The two extended ends of the bidirectional telescopic plate 15 are fixedly connected to the top plate 13. A pressing plate 17 is fixed to the front end of the first limiting plate 16. A chute 21 is formed on the top surface of the top plate 13, and two sliding seats 22 are symmetrically and slidably mounted inside the chute 21. The sliding seat 22 is fixedly connected to the bottom of the winding seat 24. The winding assembly 2 further includes a fixing bolt 23. The fixing bolt 23 is threadedly inserted into the outside of the sliding seat 22, and the fixing bolt 23 is in pressing contact with the side surface of the top plate 13. The winding shaft inside the winding seat 24 is rotatably mounted by means of a torsion spring and a bearing. A connecting shaft 26 fixedly connected to the winding shaft penetrates through the top of the winding seat 24 and rotates. First, when a person lies flat, the feet are naturally relaxed. The first limiting plate 16 contacts the outer sides of the feet in the relaxed state. The distances between the feet of different people are different. The middle plate 11 is pulled out from the storage groove 110 to adjust the distance between the two first limiting plates 16. Then, the bidirectional screw 18 is rotated to move the second limiting plate 19 close to the inner surfaces of the feet. The first limiting plate 16 and the second limiting plate 19 cooperate to limit the feet of the person. According to the different lengths of the feet of different people, the lifting screw 14 is rotated, and the bidirectional telescopic plate 15 moves along the surface of the lifting screw 14, driving the top plate 13 and the telescopic column 12 to expand, so that parts of the two connecting ropes 25 are close to the two side surfaces of the front sole. Then, the position of the winding seat 24 is adjusted inside the chute 21, so that the two connecting ropes 25 can be adjusted according to the differences at the rear ends of the soles of different people to make them contact the soles. After the adjustment is completed, it is locked by the fixing bolt 23.

[0032] In this embodiment, the measuring assembly 3 further includes a sliding rod 31. The sliding rod 31 is fixed to the outside of the top plate 13, and a sliding frame 32 is slidably sleeved on the surface of the sliding rod 31. The top of the sliding frame 32 is rotatably mounted with a knob 33 by means of a bearing. The center of the knob 33 and the center of the connecting shaft 26 are on the same vertical line. A connecting frame 34 is fixed to one side of the knob 33, and the connecting frame 34 is fixedly connected to a counter 35. By sliding the sliding frame 32 along the sliding rod 31, the position of the counter 35 can be changed. When measuring the forward extension or backward flexion of the foot, it can be switched and adjusted. According to the connection between the knob 33 and the connecting frame 34, it is convenient for the connecting plate 315 to slide along the inner slide rail 37 and the outer slide rail 36.

[0033] In this embodiment, a mounting plate 39 is provided at the top of the connecting shaft 26, and a push rod 311 is fixed to one side of the mounting plate 39. The push rod 311 moves between the inner slide rail 37 and the outer slide rail 36. An angle disc 314 is sleeved at the bottom of the connecting shaft 26, and the angle disc 314 is fixedly connected to the top of the winding base 24. A mounting plate 39 is provided at the top of the connecting shaft 26, and a push rod 311 is fixed to one side of the mounting plate 39. The push rod 311 moves between the inner slide rail 37 and the outer slide rail 36. An angle disc 314 is sleeved at the bottom of the connecting shaft 26, and the angle disc 314 is fixedly connected to the top of the winding base 24. Locking bolts 310 are threadedly inserted into the top of the mounting plate 39 and the outer surface of the ring 312, and the locking bolts 310 are in pressing contact with the top and side surfaces of the connecting shaft 26. A convex block 316 is fixed to the top of the connecting plate 315, and the convex block 316 is slidably clamped between the inner slide rail 37 and the outer slide rail 36. One end of the inner slide rail 37 and the outer slide rail 36 is fixed with a fixing frame 38, and the bottom of the fixing frame 38 is fixedly connected to the top of the winding base 24. A ring 312 is sleeved on the middle surface of the connecting shaft 26, and a magnet block 313 is fixed to one side of the ring 312 between the inner slide rail 37 and the outer slide rail 36. A metal layer is provided on the surface of the connecting plate 315, and the connecting plate 315 can be magnetically adsorbed to the magnet block 313. Initially, neither the mounting plate 39 nor the ring 312 is connected to the connecting shaft 26. Before use, it needs to be adjusted according to the foot length, width, and front sole thickness of the patient. Therefore, the two connecting ropes 25 of the two top plates 13 will have displacement and length changes, affecting the initial positions of the push rod 311 and the magnet block 313. So after the position of the winding base 24 and the length of the middle plate 11 extending out are adjusted, the mounting plate 39 is fixed to the top of the connecting shaft 26 through the locking bolt 310. The push rod 311 is located at the zero-degree angle position of the angle disc 314. Then, according to the angle required for the foot to extend forward or bend backward, it is converted into the rotation angle of the connecting shaft 26 and the winding shaft. Simply put, when the foot extends forward or bends backward, it will squeeze the corresponding connecting rope 25 to move, causing the winding base 24 at both ends of the connecting rope 25 to unwind, thereby driving the rotation of the winding shaft and the connecting shaft 26. After calculating the angle, the position of the magnet block 313 is adjusted along the angle disc 314 to the corresponding position. The front and rear groups of winding bases 24 of the top plate 13 are adjusted in this way, corresponding to the positions of the foot extending forward and bending backward respectively. Insert the connecting plate 315 into one end of the inner slide rail 37 and the outer slide rail 36, and slide the convex block 316 between the inner slide rail 37 and the outer slide rail 36. When moving to the position of the magnet block 313, the connecting plate 315 is magnetically adsorbed to the magnet block 313. Furthermore, when the foot extends forward, it drives the front-end connecting rope 25 to unwind, and the connecting shaft 26 drives the push rod 311 to rotate until it reaches the position of the connecting plate 315 and presses against the contact button 317 on one side of the connecting plate 315, so that the counter 35 performs a count. When it is necessary to change to the foot bending backward movement, manually push the connecting plate 315 to move and separate it from the magnet block 313.Pull it out along the openings of the inner slide rail 37 and the outer slide rail 36. During this process, when the connecting plate 315 moves along the paths of the inner slide rail 37 and the outer slide rail 36, it maintains its connection with the carriage 32 through the rotation of the connecting frame 34 and the rotary knob 33. After completely moving out from the front end winding base 24, the carriage 32 slides along the slide rod 31, and the counter 35 is fed into the openings of the inner slide rail 37 and the outer slide rail 36 of the rear end winding base 24 until the connecting plate 315 is adsorbed by the magnet block 313 of the rear end winding base 24 for plantar flexion training.

[0034] When using the device, the patient lies flat with their feet placed on the bottom plate 1. When a person lies flat, their feet are naturally relaxed. The first limiting plate 16 contacts the outer sides of the feet in the relaxed state. Since the distances between the feet of different people are different, the intermediate plate 11 is pulled out from the storage groove 110 to adjust the distance between the two first limiting plates 16. Then, the bidirectional screw 18 is rotated to move the second limiting plate 19 closer to the inner surfaces of the feet. The first limiting plate 16 and the second limiting plate 19 cooperate to limit the feet. According to the different lengths of the feet of different people, the lifting screw 14 is rotated, and the bidirectional telescopic plate 15 moves along the surface of the lifting screw 14, driving the top plate 13 and the telescopic column 12 to expand, so that parts of the two connecting ropes 25 approach the two side surfaces near the front soles of the feet. Then, by adjusting the position of the winding seat 24 inside the chute 21, the two connecting ropes 25 can be adjusted according to the differences at the rear ends of the soles of different people so that they contact the soles of the feet. After the adjustment is completed, it is locked by the fixing bolt 23. Therefore, displacements and length changes will occur in the two connecting ropes 25 of the two top plates 13, affecting the initial positions of the push rod 311 and the magnet block 313. So, after the position of the winding seat 24 and the extended length of the intermediate plate 11 are adjusted, the mounting plate 39 is fixed to the top of the connecting shaft 26 by the locking bolt 310. The push rod 311 is located at the zero-degree angle position of the angle dial 314. Then, according to the angle required for the foot to extend forward or flex backward, it is converted into the rotation angle of the connecting shaft 26 and the winding shaft. Simply put, when the foot extends forward or flexes backward, it will squeeze the corresponding connecting rope 25 to move, causing the winding seats 24 at both ends of the connecting rope 25 to unwind, thereby driving the rotation of the winding shaft and the connecting shaft 26. After calculating the angle, the position of the magnet block 313 is adjusted along the angle dial 314 to the corresponding position. The front and rear groups of winding seats 24 of the top plate 13 are adjusted in this way, corresponding to the positions of the foot extending forward and flexing backward respectively. The connecting plate 315 is inserted into one end of the inner slide rail 37 and the outer slide rail 36. The convex block 316 slides between the inner slide rail 37 and the outer slide rail 36. When it moves to the position of the magnet block 313, the connecting plate 315 is magnetically adsorbed to the magnet block 313. Furthermore, when the foot extends forward, it drives the front-end connecting rope 25 to unwind, and the connecting shaft 26 drives the push rod 311 to rotate until it reaches the position of the connecting plate 315 and presses against the contact button 317 on one side of the connecting plate 315, so that the counter 35 makes one count. When it is necessary to change to the foot flexing backward movement, the connecting plate 315 is manually pushed to move, separating it from the magnet block 313 and pulling it out from the openings of the inner slide rail 37 and the outer slide rail 36. During this process, when the connecting plate 315 moves along the paths of the inner slide rail 37 and the outer slide rail 36, it maintains its connection with the carriage 32 through the rotation of the connecting frame 34 and the knob 33. After completely moving out of the front-end winding seat 24, the carriage 32 slides along the slide rod 31, and the counter 35 is inserted into the openings of the inner slide rail 37 and the outer slide rail 36 of the rear-end winding seat 24 until the connecting plate 315 is adsorbed to the magnet block 313 of the rear-end winding seat 24 for foot flexing backward training.
