The present invention will be specifically described below with reference to the accompanying drawings:

As shown in FIG. 1 and FIG. 2, the domestic warm physiotherapy bed with the function of the leg 4 includes the upper body 1, the lower bed 2 and the control device (not shown), and the periphery of the lower bed 2 is arranged. There is a bed support ² 1 , a groove 2 ^{2 is} arranged in the middle of the lower bed body, and two tracks 23 are arranged on the left and right sides of the bottom of the upper and lower bed bodies in the bottom of the groove 22, and the massage frame 24 is arranged on the two tracks 23 . The massage frame 24 is provided with a massage wheel 25, and the massage wheel 25 is rotatable about its own axis. The axis of the massage wheel 25 is parallel to the bed surface of the lower bed, perpendicular to the moving direction of the massage frame 24, and the massage wheel 25 passes through the bracket. 26 is mounted on the massage frame 24, and a driving motor 27 is disposed at one end of the groove 22 along the axial direction of the upper and lower bed bodies. A driving wheel 28 is mounted on the output shaft of the motor 27, and a driven wheel is disposed at the other end of the groove 22. 29, the driving wheel 28 and the driven wheel 29 are surrounded by a transmission belt 30, and both ends of the transmission belt 30 are fixed on the massage frame 24.

In operation, the control device controls the operation of the drive motor 27 and drives the massage frame 24 to reciprocate along the track 23 via the motor 27, the drive wheel 28, the driven wheel 29, the drive chain or the drive belt 30.

Both ends of the recess 22 are provided with a travel switch 37 through which the limit position of the massage frame 24 to both ends is limited.

Two massage wheels 25 are arranged side by side in the direction of the bed surface of the massage wheel bracket 26 in parallel with the bed surface. The massage wheel bracket 26 is hingedly mounted on the mounting seat 38 provided on the massage frame 24, and the massage wheel bracket 26 hinge shaft and the massage wheel 25 The axis is parallel and centered below the massage wheel 25, and the massage wheel bracket 26 is pivotable about its hinge axis.

The track 23 in the above embodiment is a straight track, the cross-sectional shape of which is a transverse U-shape, the U-shaped openings of the two tracks are oppositely arranged, and the traveling wheel of the massage frame is clamped by the dome-shaped structure; the massage wheel 25 is a cylinder The surface has a plurality of massage grooves 251 (see Fig. 6) distributed along the circumference thereof. In the case of ensuring the massage effect, the surface of the massage wheel 25 can also be replaced by a plurality of uniformly distributed protrusions (not shown), and the shape of the massage wheel 25 can also be used other than a cylindrical shape. Appropriate shape. The above-mentioned transmission belt 30 adopts a timing belt, and a transmission chain or a transmission chain plus a traction rope can also be adopted. When the transmission chain is adopted, both ends of the transmission chain are fixed on the pressing frame 24; when the structure of the transmission chain and the traction rope is adopted, both ends of the transmission chain are connected with the massage frame 24 through the traction rope, which is convenient for connection.

3 to 6 show a second embodiment of the present invention, in which, In contrast to an embodiment, in addition to setting the tunnel 23 to an oblique track that gradually rises from the outer end of the lower bed 2 to the inner end that is in contact with the upper bed 1, it is also between the two tracks 23. A pair of straight rails 31 are disposed at the bottom of the recess 22, and the pair of straight rails 31 are symmetrically arranged on both sides of the belt 30. The cross-sectional shape of the straight rails 31 is also a transverse U-shape, and the dome-shaped openings of the two rails 31 are opposite.

A carriage 32 is disposed between the two guide rails 31. The carriage 32 is also clamped in the serpentine groove of the guide rail 31 through the traveling wheels 39 (see FIG. 5) on both sides thereof. The carriage 32 is also rotated on the rotary shaft of the traveling wheel. Two swinging rods 33 are rotatably mounted, and the free ends of the two swinging rods 33 are rotatably connected to a mounting seat 34. The mounting seat 34 is fixed to the bottom of the four-wheeled carriage 24 by screws, and both ends of the transmission belt 30 pass through the pressing plate 35 and The screw is pressed 3⁄4" on the carriage 32.

During operation, the frame 24 moves along the track 23, and its height fluctuates up and down with the change of the track surface. At the same time, the carriage 32 moves linearly along the guide rail 31, and the swing lever 33 on the carriage 32 follows The movement of the massage frame 24 and the carriage 32 is swung about the hinge axes at both ends thereof.

After the massage frame 24, which is composed of the guide rail 31, the carriage 32, and the swing lever 33, is provided at the bottom of the recess 22, the drive belt is connected to the carriage 32, and the drive motor 27 drives the massage frame through the transmission belt 30 and the auxiliary drive mechanism. During the movement of the carriage 32, the height position of the carriage 32 is constant with respect to the driving wheel 28 and the driven wheel 29, thereby also keeping the tension state of the belt 30 constant, thereby making the belt 30 reliable. Work provides protection. However, if the belt 30 is directly attached to the massage frame 24, the tension of the belt 30 will vary with the height of the massage frame 24 on the rail 23, and thereby the belt 30 will be damaged.

The bottom of the recess 22 may also be provided with a tensioning mechanism of a transmission belt 30 composed of a tensioning pulley and a tensioning wheel supporting arm in the prior art.

As shown in Fig. 7, the track 23 of the massage frame 24 can also be arranged in a wave shape according to the natural shape of the leg when the person is in the massage bed.

In order to provide the user with a more perfect health environment with warm function, as shown in FIG. 1 and FIG. 3, a heating plate 36 can also be arranged at the bottom of the groove 22.
