[0028] like Figure 2 As shown, the chair mechanism 3 includes: a seat 301, a backrest 302, a hip support belt 303, a limit baffle 304, a connecting bolt rod 305, a limit pressure piece 306, a joint limit piece 307, a compression spring 308, and a limit slide 309. The seat 301 is a circular ring structure, the middle of which is fixedly connected to the backrest 302, the inner side of the seat 301 is movably connected to the hip support belt 303, and the limit baffle 304 is snap-connected to the bottom edge of the seat 301.

[0029] The hip support belt 303 supports the patient's crotch and is made of its own soft material. It can be squeezed and folded to change its usage form so that the patient can use it when sitting or standing.

[0030] like Figure 3 and Figure 4As shown, a hole is provided on the limit baffle 304, and the hole is a threaded hole. The limit pressure piece 306 is arranged on the inner side of the limit baffle 304, and one end of the connecting bolt rod 305 passes through the hole and is movably connected to the limit pressure piece 306 through a bearing.

[0031] The inner side of the limiting pressure piece 306 is embedded and clamped with the two joint limiting pieces 307 , and the compression spring 308 is provided at the connection between the limiting pressure piece 306 and the joint limiting pieces 307 .

[0032] By setting the compression spring 308, it is caused to contract when the connecting bolt rod 305 is locked, and through its elastic action, the locking force of the connecting bolt rod 305 is buffered, so as to avoid that the locking force of the connecting bolt rod 305 is too large, so that the limiting pressure of the joint limiter 307 on the patient's joint is too strong, thereby causing damage to the patient's legs, thereby improving the safety and protection of its use, and enhancing its practicality.

[0033] like Figure 5 As shown, two limiting slide grooves 309 are provided on the back of the chair back 302 , and the limiting mechanism 4 is connected to the seat mechanism 3 at the limiting slide grooves 309 .

[0034] By opening the limiting slide groove 309, the limiting mechanism 4 can slide along the extension direction when in use to adjust the use height of the limiting mechanism 4, thereby improving the applicability of the device to patients of different heights when in use, improving its applicability, and enhancing the convenience of its use and adjustment.

At the same time, through the action of the winding member 402, the Velcro strap 403 is wound up to adjust its use length, so that it is suitable for patients with different body widths, thereby improving its applicability.

[0038] As a preferred embodiment of the present invention, the number of the electric push rods 103 is three, and the three electric push rods 103 are all synchronous electric push rods.

[0039] By setting the electric push rod 103, the connecting frame 2 and the seat mechanism 3 thereon are pushed to adjust the height of use, and by setting three electric push rods 103, they are evenly distributed on the circumference below the connecting frame 2 to ensure its stability in use. At the same time, the three electric push rods 103 are all synchronous electric push rods, which effectively maintain the synchronization of the rising and falling of the connecting frame 2 and the seat mechanism 3 thereon, avoiding the connection frame 2 from tilting due to the lifting and lowering, resulting in the connection frame 2 2 The height adjustment is stuck, thereby improving the fluency of the height adjustment of the connecting frame 2 and its efficiency in use.

[0040] The patient who needs to be trained is placed in the chair seat 301, and the hip support belt 303 is used to support the patient's crotch and the patient himself, so as to adjust the position and placement of the patient's legs, and the connecting bolt rod 305 is rotated to push the limiting pressure piece 306 to move toward the placed patient's legs, so as to make the joint limiting piece 307 on the limiting pressure piece 306 gradually fit with the patient's legs to limit the patient's legs, avoid bending of the patient's legs during standing training, and thus affect the training recovery cycle, ensure the stability of its limited use, and after fitting, stop rotating the connecting bolt rod 305, so as to make the patient lean and fit on the chair back 302, and limit it through the limiting mechanism 4 to ensure its stability in use and improve its convenience in operation.

[0041] As a preferred embodiment of the utility model, the number of the limit baffles 304 is two, and the two limit baffles 304 are symmetrically arranged front and back with the mid-perpendicular line of the seat 301 as the symmetry axis. The two limit baffles 304 are respectively engaged and connected to the front and back sides of the bottom of the seat 301, and the component settings on the two limit baffles 304 are the same.

[0042] When the device is in use, the limiting baffles 304 bidirectionally arranged at the bottom of the front and back of the seat 301 can effectively limit the legs of a patient sitting in the seat 301 in both directions on the front and back, so as to avoid bending of the patient's legs during standing training, thereby affecting the training recovery cycle. At the same time, the limiting baffles 304 at the bottom of the front of the seat 301 and the limiting baffles 304 at the bottom of the back of the seat 301 are arranged in the same way to ensure the symmetry and stability of the bidirectional limitation, so as to avoid loosening of the limitation of the patient's legs during training, thereby affecting the rehabilitation training effect, thereby effectively improving the stability and practicality of its use.

[0043] The steps for using the device are as follows:

[0044] The patient who needs to be trained is placed in the chair seat 301, and the crotch of the patient and the patient are supported by the hip support belt 303, and then the patient's legs are adjusted to make the patient's legs straight and side by side, and the connecting bolt rod 305 is rotated to push the limiting pressure piece 306 to move toward the placed patient's legs, so that the joint limiting piece 307 on the limiting pressure piece 306 gradually fits with the patient's legs to limit the patient's legs, and after fitting, the rotation of the connecting bolt rod 305 is stopped to lock it through the threaded action on the connecting bolt rod 305, so that the patient leans and fits on the chair back 302, and according to the patient's height, the setting of the connecting slide 401 is used to drive the limiting mechanism 4 to slide along the extension direction of the limiting slide groove 309, and the use height of the limiting mechanism 4 is adjusted to make it suitable According to the height of the patient, the Velcro strap 403 is passed around the patient's armpit and adhered accordingly to bind and limit the patient's body leaning on the chair back 302, ensuring the standardization and continuity of the patient's body movement while leaning on the chair back 302. When standing training is required, the three electric push rods 103 are pushed synchronously to push the connecting frame 2 and the seat mechanism 3 thereon to adjust the height of use, and drive the patient's upper body on the hip support belt 303 to move up, and then gradually make the patient stand up, and then stop the operation of the electric push rod 103. On the other hand, after completing the standing training, the electric push rod 103 is operated synchronously to drive the patient's upper body to move down, so that the patient can sit on the hip support belt 303 for a proper rest, avoiding injuries caused by excessive standing training of the patient, and facilitating its use.

[0045] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Those skilled in the art can still adjust the technical solutions recorded in the above embodiments, or replace some of the technical features by equivalents.
