Description

Home warm physiotherapy bed

Technical field

The invention belongs to the technical field of medical care, and particularly relates to a domestic warm physiotherapy bed. Background technique

The Chinese utility model patent of the applicant's earlier application No. 03240502. 2 discloses a domestic warm physiotherapy bed which is provided with a massage frame, a massage jade ball, a motor drive mechanism, and a fever in the upper body thereof. Devices such as devices and thermostats can simultaneously perform physical therapy and health care such as massage, massage and hot compress on the back of the human body. The motor drive mechanism comprises a motor, a motor wheel, a guide wheel and a traction line, and the traction wire is wound around the motor wheel and the guide wheel, and both ends thereof are connected with the massage frame, and the motor drives the massage frame to move along the track through the traction line. In order to ensure reliable driving of the motor to the massage frame and prevent the traction line from sliding relative to the motor wheel or the guide wheel, the physiotherapy bed uses a drive chain or a timing belt as a traction line. In order to make the movement curve of the massage jade ball better coordinate with the curve of the back of the human body, the above-mentioned physiotherapy bed also adopts a curved orbit with curved concave and convex. However, after the drive chain or the timing belt is selected as the traction line, and the curved track with the curved concave and convex is adopted, since the massage frame changes continuously in the vertical direction relative to the motor wheel and the guide wheel, the tension of the traction line is caused. Constantly changing, and this change in tension not only affects the smooth operation of the massage frame, but also causes premature failure of the drive chain or timing belt. Summary of the invention

In view of the above problems, an object of the present invention is to provide a domestic warm physiotherapy bed in which the tension line of the traction line is unchanged and the massage frame is stable.

In order to achieve the above objectives, the twisting solution of the present invention is:

The utility model relates to a household warm physiotherapy bed, which comprises an upper bed body and a lower bed body, wherein a bed circumference support is arranged around the upper bed body, a groove is arranged in the middle of the upper bed body, and a pair of opposite groove bottoms are arranged on the left and right sides of the groove bottom along the length direction thereof. a curvilinear track with curved and concave curves, a massage frame is arranged on the pair of curved tracks, a massage jade ball or a massage wheel is arranged on the massage frame, and a driving wheel with a driving wheel mounted on the output shaft is respectively arranged at both ends of the groove length direction The motor and the driven wheel, the axes of the driving wheel and the driven wheel are parallel to each other, and the driving wheel or the synchronous belt is wound around the driving wheel and the driven wheel, and a pair of straight rails are arranged at the bottom of the groove below the massage frame, and the pair of straight rails are symmetrically active The wheel and the driven wheel are disposed on a plane, and a sliding frame is disposed between the two straight rails. The sliding frame is mounted on the two straight rails through the traveling wheels disposed on both sides thereof, and the swinging rod is hinged with a swinging rod, and the upper end of the swinging rod is The bottom of the massage frame is hingedly connected, the transmission chain or the timing belt is connected with the sliding frame, and the massage frame is driven by the sliding frame. When the sliding frame moves along the curved orbit of the massage frame, the swinging rods respectively rotate around the hinge axes of the two ends. swing.

Further, the bottom of the groove is further provided with a tensioning mechanism of the transmission chain or the timing belt. Further, both ends of the bottom of the groove are provided with a travel switch, and the travel switch cooperates with the sliding frame or cooperates with the massage frame to perform the position of the massage frame at the extreme ends of the groove limited. Further, the bottom of the groove is further provided with a plate type heating element, and the plate type heating element is located below the massage frame and outside the two straight guide rails.

The invention eliminates the prior art by directly connecting the massage chain or the synchronous belt to the massage frame by providing an intermediate connecting mechanism composed of a straight rail, a sliding frame and a swinging rod between the massage frame and the transmission chain or the timing belt. The series of problems brought about by the smooth operation of the massage frame and the normal operation of the drive chain or timing belt. DRAWINGS

Figure 2 is an enlarged view of A-A in Figure 1;

Fig. 3 is an enlarged view of a portion B in Fig. 1. detailed description

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

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the domestic warming physiotherapy bed comprises a lower bed body 1 and an upper bed body 2 , a bed surrounding support 14 is arranged around the upper bed body 2 , and a groove 13 is arranged in the middle of the upper bed body 2 . The bottom of the groove 13 is provided on the left and right sides of the longitudinal direction thereof with a pair of curved tracks 12 with respect to the height of the bottom of the groove. The pair of curved tracks 12 are provided with a massage frame 5, and the massage frame 5 is provided with a massage jade ball. Or the massage wheel (not separately labeled), the two ends of the groove 13 are respectively provided with a drive motor 15 and a driven wheel 20 on which the drive wheel 16 is mounted on the output shaft, and the axes of the drive wheel 16 and the driven wheel 20 are parallel to each other, and the drive wheel 16 and the driven wheel 20 are wound with a timing belt 17, and a bottom of the groove 13 below the massage frame 5 is further provided with a pair of straight rails 11 which are arranged in the plane of the driven wheel 20 and the two straight rails 11 A carriage 6 is disposed between the two sides of the straight rail 11 through the traveling wheels 10 disposed on both sides thereof. A pair of swing rods are hinged on the sliding frame, the upper end of the pair of swing rods 7 is connected with the bottom of the massage frame 5 through the mounting seat 8, and the swing rod 7 is hingedly connected with the mounting seat 8, and the two ends of the timing belt 17 pass through the pressing plate 9. The swing frame 6 is pressed and moved by the carriage 6 to move the massage frame 5. When the carriage 6 moves along the curved track 12 of the massage frame 5, the swing bars 7 swing around the hinge axes of the two ends.

Both ends of the rail 12 are provided with a travel switch 4 which cooperates with the massage frame 5 to define an extreme operating position of the massage frame 5 at both ends of the recess 13. The travel switch 4 can also cooperate with the carriage 6 (not shown;) to define the extreme operating position of the massage frame 5 at both ends of the recess ¹³ .

In order to facilitate the adjustment of the tension of the timing belt 17, a conventional tensioning wheel tensioning mechanism 19 is also provided at the bottom of the recess 13.

In order to provide the user with a warm physiotherapy environment, a plate heating element 18 is also provided at the bottom of the recess 13 below the massage frame 5.

The cross section of the straight rail 11 is a dome shape. The timing belt 17 can also be used with a drive chain.

During operation, the massage frame 5 moves along the track 12, and its height fluctuates up and down with the change of the track surface. At the same time, the carriage 6 moves linearly along the guide rail 11, and the swing bar 7 on the carriage 6 follows the massage. The movement of the frame 5 and the carriage 6 is swung around the hinge axes at both ends thereof.

After the auxiliary frame of the massage frame 5 composed of the guide rail 1 1 , the carriage 6 and the swing rod 7 is disposed at the bottom of the groove 13 , the timing belt 17 is connected to the carriage 6 , and the drive motor 15 passes through the timing belt 17 and the auxiliary drive. The mechanism drives the massage frame 5 to move. During the movement of the carriage 6, the height position of the carriage 6 is always unchanged with respect to the driving wheel 16 and the driven wheel 20, thereby also keeping the tension state of the timing belt 17 constant. This provides a guarantee for the reliable operation of the timing belt 17.
