DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-8 As shown, the utility model provides a training device for preventing lower limb venous thrombosis, comprising a vertical board 1, two mounting components 6 are provided at the bottom end of the vertical board 1, a central shaft 7 is installed at the front side of the vertical board 1 through a bearing, and a detachable training mechanism is installed at the front end of the central shaft 7;

[0033] The rear end of the central shaft 7 extends to the rear side of the vertical plate 1 and is fixed with a rotating wheel 13, on which a plug hole 14 is provided. A locking assembly 9 is provided at the bottom of the central shaft 7, and the locking assembly 9 can limit the rotation of the central shaft 7;

[0034] The exercise mechanism includes a sleeve 2, a connecting sleeve 3 is fixedly provided at the midpoint of the outer end of the sleeve 2, and the connecting sleeve 3 is installed at the front end of the central shaft 7. Slide rods 4 are provided at both ends of the sleeve 2, and one end of the slide rod 4 extends into the interior of the sleeve 2 and is fixedly provided with a button 15, and the button 15 can control the locking assembly 9;

[0035] A gravity ball 16 is provided inside the sleeve 2, and the gravity ball 16 is provided between two slide bars 4, and a fixing assembly 5 for fixing the lower limbs is installed at the other end of the slide bar 4;

[0036] A controller 11 and a counting switch 12 are installed on the rear side of the vertical board 1. The counting switch 12 is arranged at the input end of the controller 11, and the button 15 is arranged at the input end of the counting switch 12, so as to calculate the number of exercises and control the locking component 9.

[0037] The vertical board 1 is fixed to the end of the bed through the clamping plate 6, and the bed board is inserted between the two clamping plates 6. After tightening the bolts, the exercise equipment can be fixed to the end of the bed. When exercising, the patient's legs are fixed to the two fixing components 5 respectively, and the two fixing components 5 are connected to the two slide bars 4. The whole exercise mechanism is installed at the front end of the central axis 7. The central axis 7 and the exercise mechanism together form a lever structure, and the patient's legs are respectively at both ends of the lever. One leg exerts force downward and the other leg moves upward. The legs move up and down alternately, thereby achieving the purpose of exercising the lower limbs. In addition, the exercise equipment is fixed at the end of the bed, so that the patient can exercise the lower limbs while lying on the bed. It is suitable for patients who find it difficult to stand, has a wider range of application, and has a better exercise effect.

[0038] During the exercise, the central axis 7 is driven by the exercise mechanism to rotate alternately left and right, thereby driving the rotating wheel 13 to rotate left and right. At the same time, the two ends of the sleeve 2 are repeatedly tilted left and right. Each time the leg is exercised, the sleeve 2 will tilt once. When the sleeve 2 tilts, the gravity ball 16 will roll in the tilting direction under the action of gravity, thereby squeezing and triggering the button 15 on the corresponding side. After the button 15 is pressed, it will be counted once by the counting switch 12. Therefore, the counting switch 12 will count once for each leg exercise. The number of exercises can be set according to the recovery of the patient's lower limbs. When the number of exercises reaches the set number, the counting switch 12 controls the locking component 9 through the controller 11 to fix the rotating wheel 13, thereby fixing the central axis 7, so that the patient can no longer exercise, thereby limiting the number of exercises for the patient and avoiding injuries caused by excessive exercise.

[0039] The central shaft 7 can be fixed by the locking assembly 9 so that it cannot rotate any more. Figure 4 , 5 As shown, the locking assembly 9 includes an outer tube 901 fixedly mounted on the vertical plate 1, an iron rod 902 is arranged inside the outer tube 901, and a spring 903 is fixedly mounted at one end of the iron rod 902;

[0040] A detachable end plate 905 is installed at one end of the outer tube 901, and an electromagnet 904 is fixed on the end plate 905. One end of the spring 903 is connected to the electromagnet 904. In the locked state, the outer tube 901 is aligned with the socket 14 so that the iron rod 902 can be inserted into the socket 14, thereby fixing the rotating wheel 13 and the central axis 7. The electromagnet 904 is arranged at the output end of the controller 11.

[0041] In the exercise state, the electromagnet 904 is energized, thereby generating a magnetic force to attract the iron rod 902, causing the iron rod 902 to shrink in the outer tube 901, and the spring 903 is compressed. When the number of exercises reaches the set value, the counting switch 12 controls the controller 11 to cut off the power to the electromagnet 904, and the elastic force of the spring 903 pushes the iron rod 902. When the rotating wheel 13 drives the socket 14 to rotate again to align with the outer tube 901, the iron rod 902 will be inserted into the socket 14, thereby fixing the rotating wheel 13 and the central axis 7.

[0042] Exercise requires a certain intensity to be effective, such as Figure 2 , 3 As shown in Figure 7, an outer ring 8 is fixedly provided at the outer end of the central axis 7, and a torsion spring 10 is fixedly provided at the rear side of the outer ring 8. One end of the torsion spring 10 is fixedly connected to the vertical plate 1. The torsion spring 10 can provide appropriate resistance for the movement of the lower limbs, thereby improving the exercise effect.

[0043] Two slideways are provided at the top of the sleeve 2, and a screw is fixed at the top of the slide rod 4. The tops of the two screws extend to the top of the sleeve 2 through the slideways and are equipped with nuts, which can limit the angle and telescopic degree of the slide rod 4.

[0044] In the absence of external force, the elastic force of the torsion spring 10 maintains the sleeve 2 in a horizontal state. During exercise, the sleeve 2 repeatedly tilts up and down and drives the central axis 7 to rotate. The central axis 7 drives the outer ring 8 to rotate, and the outer ring 8 drives the torsion spring 10 to tighten, so that the exercise has resistance and improves the exercise effect. The slide bar 4 can be extended and retracted inside the sleeve 2 to adjust the distance between the two fixing components 5 according to the patient's body shape and keep the positions of the two fixing components 5 on both sides of the connecting sleeve 3 symmetrical. During the extension and retraction process of the slide bar 4, the screw moves along the slide. After adjustment, the position of the slide bar 4 can be fixed by tightening the nut.

[0045] The lower limbs are fixed to the exercise equipment by the fixing assembly 5. Figure 1 , 6 As shown, the fixing assembly 5 includes a support plate 501, the top of which is inlaid with a cushion 502 having a buffering effect, which can improve the comfort of the lower limbs when fixed, and two elastic straps 503 are fixedly provided on the top of the support plate 501;

[0046] The fixing assembly 5 further includes a connecting rope 505 . The top ends of the connecting ropes 505 of the two fixing assemblies 5 are respectively connected to the two sliding rods 4 . The bottom ends of the connecting ropes 505 are fixed with a fixing frame 504 . Both ends of the fixing frame 504 are connected to the support plate 501 .

[0047] The legs are placed on the top of the support plate 501, and the soft pad 502 is in direct contact with the legs, which improves the comfort of the legs. At the same time, the legs are bound to the top of the support plate 501 using elastic straps 503, and the support plate 501 is connected to the slide bar 4 through a fixing frame 504 and a connecting rope 505, thereby connecting the legs to the exercise equipment.

[0048] In order to store the exercise equipment, Figure 1 , 8 The mounting assembly 6 shown includes two mounting beams 601, the front mounting beam 601 is hinged at the bottom end of the vertical plate 1, a telescopic rod 602 is provided between the two mounting beams 601, and both ends of the telescopic rod 602 are fixedly connected to the two mounting beams 601 respectively;

[0049] Suction cups 603 are installed at the bottom of both ends of the mounting beam 601 , and a support rod 604 is hinged to the top end of the mounting beam 601 on the rear side, and the top end of the support rod 604 is hinged to the rear side of the vertical board 1 .

[0050] When in use, the mounting assembly 6 is fixed on the bed as a whole by suction cup 603, the vertical board 1 is perpendicular to the bed body, and the telescopic rod 602 is in a retracted state. When not in use, the connection between the suction cup 603 and the bed body is released, and then the vertical board 1 is pushed backward to rotate it backward and gradually fall down. During this process, the support rod 604 pushes the rear mounting beam 601 as the vertical board 1 tilts backward, thereby increasing the distance between the two mounting beams 601, and the telescopic rod 602 is thus lengthened until the vertical board 1 is laid down to be parallel to the telescopic rod 602, so that the vertical board 1 is folded for easy storage without taking up too much space.

[0051] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
