[0007] Furthermore, the worm gear transmission mechanism includes a rocker wheel arranged outside the seat support shell, a worm shaft is correspondingly arranged inside the seat support shell, the rocker wheel is installed on the shaft end of the worm shaft extending outside the seat support shell, and a worm wheel is installed on the seat support shell corresponding to the worm shaft.

[0008] Furthermore, the seat support shell includes a vertical support plate and a transverse support plate installed in the inner space of the vertical support plate. The transverse support plate is divided into an upper transverse support plate and a lower transverse support plate. A worm gear is installed at the lower end of the lower transverse support plate.

[0009] Furthermore, the screw transmission mechanism includes a lifting screw coaxially mounted with the worm gear, the lifting screw is correspondingly provided with a lifting nut, the lifting nut is correspondingly provided with a lifting plate, and the lifting plate is correspondingly provided with a seat mounting seat;

[0010] A lifting guide shaft is installed between the upper transverse supporting plate and the lower transverse supporting plate, and the lifting plate is slidably installed on the lifting guide shaft.

[0011] Furthermore, the lifting screw and the lifting nut are driven by a ball screw.

[0012] Furthermore, two worm support seats are installed on the vertical support plate corresponding to the worm shafts.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model enhances body posture adaptability: by adding a seat lifting function, the utility model can accurately adjust according to the body posture differences of different patients, so that the seat height and angle are more in line with the actual needs of the patients, thereby improving the comfort and effect of sports rehabilitation.

[0015] Compact and stable structure: The combined design of worm drive mechanism and screw drive mechanism makes the entire seat lifting device compact in structure and occupies little space, while ensuring the stability and reliability of the lifting process.

[0016] Easy to operate: The worm drive mechanism is controlled by an external rocker, which in turn drives the screw drive mechanism to raise and lower the seat. The operation is simple and intuitive, and the patient or rehabilitation therapist can easily complete the adjustment.

[0017] High lifting precision: The lifting screw and lifting nut are driven by ball screw, which has the advantages of high transmission efficiency, low friction resistance and high lifting precision, ensuring the accuracy and stability of the seat lifting. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example 1

[0028] like Figures 1 to 4 As shown, the seat lifting device suitable for sports rehabilitation equipment described in the utility model includes a seat support shell 3, a worm transmission mechanism 1 is correspondingly installed on the seat support shell 3, a screw transmission mechanism 2 is correspondingly installed on the output wheel of the worm transmission mechanism 1, and a seat mounting seat 4 that can move up and down is correspondingly provided on the screw transmission mechanism 2.

[0029] The up and down movement is achieved through the screw transmission mechanism 2, and the self-locking function is achieved through the worm transmission mechanism 1, while the transmission characteristics of the ball screw transmission are well taken into account.

[0030] The worm gear transmission mechanism 1 includes a rocker wheel 11 arranged on the outside of the seat support shell 3, and a worm shaft 12 is correspondingly arranged inside the seat support shell 3. The rocker wheel 11 is installed on the shaft end of the worm shaft 12 extending to the outside of the seat support shell 3, and a worm wheel 13 is installed on the seat support shell 3 corresponding to the worm shaft 12.

[0031] The seat support shell 3 includes a vertical support plate 32 and a transverse support plate installed in the inner space of the vertical support plate 32 . The transverse support plate is divided into an upper transverse support plate 33 and a lower transverse support plate 31 . The worm gear 13 is installed at the lower end of the lower transverse support plate 31 .

[0032] The screw transmission mechanism 2 includes a lifting screw 24 coaxially mounted with the worm gear 13, the lifting screw 24 is correspondingly mounted with a lifting nut 21, the lifting nut 21 is correspondingly mounted with a lifting plate 22, and the lifting plate 22 is correspondingly mounted with a seat mounting base 4;

[0033] A lifting guide shaft 23 is installed between the upper transverse support plate 33 and the lower transverse support plate 31 , and the lifting plate 22 is slidably installed on the lifting guide shaft 23 .

[0034] The lifting screw 24 and the lifting nut 21 are ball screw driven, which has the advantages of high transmission efficiency, low friction resistance, and high lifting accuracy, ensuring the accuracy and stability of the seat lifting.

[0035] Two worm support seats 14 are installed on the vertical support plate 32 corresponding to the worm shaft 12 .

[0036] Working process or working principle:

[0037] During the lifting action, the handle of the crank wheel 11 is held and shaken, and the crank wheel 11 will drive the worm shaft 12 to rotate, and the horizontal rotational motion is converted into longitudinal rotational motion through the worm gear 13. The rotation of the worm gear 13 also drives the lifting screw 24 to rotate, so that the lifting nut 21 will generate an up and down movement driven by the rotation of the lifting screw 24, and the seat mounting base 4 and the seat are driven to realize the lifting function at the same time through the lifting plate 22 connected thereto.

[0038] The description of the direction and relative position relationship of the structure in the utility model, such as the description of front, back, left, right, up and down, does not constitute a limitation of the utility model and is only for the convenience of description.
