In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1, an embodiment of the present invention provides a massage medical bed, wherein the bed body includes a bed head 1 and a bed tail 2, and the whole bed body is supported by a bed frame 3. The bed tail 2 is composed of a plurality of strip-shaped bed boards, the bed boards are divided into movable bed boards 4 and fixed bed boards 5, the movable bed boards 4 and the fixed bed boards 5 are arranged in a staggered mode at intervals and can move relative to the fixed bed boards 5. In the present embodiment, the patient is driven by a driving mechanism provided at the bottom end of the movable bed plate 4 so as to perform a reciprocating movement up and down with respect to the fixed bed plate 5, thereby massaging the lower body of the patient when the patient lies on the bed, promoting blood circulation, and preventing the occurrence of cocklebur.

Specifically, referring to fig. 2, the driving mechanism includes a first motor 6, the first motor 6 drives the driving bevel gears 8 on the output shafts at both ends of the bevel gear steering gear 7 to rotate, and at the same time, a rotatable cam shaft 9 is respectively disposed at both sides of the bed frame 3, and a driven bevel gear 10 is disposed at an end thereof and is respectively engaged with the driving bevel gear 8 at a corresponding side. The bottom ends of the two sides of the movable bed board 4 are respectively provided with a bearing rod 11, the side part of the movable bed board 4 is fixedly connected with the bearing rods 11 through vertical support rods 12, and the cam shaft 9 is connected with the bearing rods 11 through a plurality of cam structures. Therefore, under the drive of the first motor 6, the cam shaft 9 is driven to rotate by the meshing transmission of the bevel gears, so that the cam structure drives the bearing rod 11 and the movable bed plate 4 to reciprocate up and down to form a height difference with the fixed bed plate 5, and the massage on the legs and the buttocks of the human body is realized.

Referring to fig. 3, in the present embodiment, each cam structure includes two cams 13 sleeved on the cam shaft 9, an eccentric rotating shaft 14 is disposed at a non-midpoint position of the two cams 13, and the cam shaft 9 is disconnected at this position, and the eccentric rotating shaft 14 and the two cams 13 are integrally connected to form a rotating shaft structure. A connecting plate 15 is hinged and sleeved on the eccentric rotating shaft 14, and the other end of the connecting plate 15 is hinged with a hinge seat 16 arranged on the lower surface of the bearing rod 11. Therefore, when the camshaft 9 rotates, the eccentric rotating shaft 14 will drive the bottom end of the connecting plate 15 to eccentrically rotate around the camshaft 9, and under the condition that the movable bed board 4 is limited to only vertically displace, the connecting plate 15 hinged with the hinge seat 16 of the bearing rod 11 will drive the bearing rod 11 and the movable bed board 4 to vertically reciprocate.

As another embodiment of the present invention, all the bed boards can be set as movable bed boards 4, meanwhile, the bearing rods 11 on both sides are respectively connected with the movable bed boards 4 at different intervals, and the cam shafts 9 on both sides form a phase difference, preferably 180 degrees, so that the cam shafts 9 drive the movable bed boards 4 to reciprocate up and down under the driving of the first motor 6, and because two adjacent movable bed boards 4 have a phase difference of 180 degrees, the height change formed between the movable bed boards 4 is more obvious, and the massage intensity for the human body is higher.

Wherein, for guaranteeing that the vertical reciprocating motion of activity bed board 4 is reliable in order, be provided with a plurality of recesses at the part that bedstead 3 supports the bed board, the both sides of activity bed board 4 slide and set up in the recess that corresponds, and the bottom of recess is provided with the step simultaneously to the minimum displacement of restriction activity bed board 4 prevents that it from dropping. In addition, the first motor 6 of the driving mechanism, the bevel gear steering gear 7, the cam shaft 9 and the like are all arranged on a mounting frame 17, and the end part of the mounting frame 17 is fixedly connected with the bedstead 3.

On the other hand, the bed head 1 of the present invention also has the functions of lifting and massaging, and is specifically realized by the following structure: the bed head 1 is composed of a plurality of bed head boards 18, the bed frame 3 supporting the bed head boards 18 is hinged with the bed frame 3 of the bed tail 2, a lifting cylinder 19 is arranged below the bed head boards 18, the bottom end of the lifting cylinder is fixedly arranged on the bed frame 3, the end part of a piston rod is hinged with the bottom end of the bed head boards 18, the bed head boards 189 and the corresponding bed frame 3 are driven to rotate around the bed tail 2 through the extension of the piston rod, the function of lifting the bed head 1 is realized, and the sitting of a patient is facilitated.

Meanwhile, a massaging structure is also arranged on the headboard 18 to massage the back of the patient. Referring to fig. 4, the headboard 18 in the middle of the head 1 is hollow, and the silicone balls 20 are disposed at the hollow to form a plurality of rows of silicone ball 20 massage parts. Each row of silica gel balls 20 are connected through a connecting rotating shaft 21, and the silica gel balls 20 are eccentrically arranged on the connecting rotating shaft 21. A synchronous pulley 22 is provided at an end of the connection shaft 21, and a second motor 23 installed on the frame 3 drives a synchronous belt 24 to rotate all the synchronous pulleys 22 and the connection shaft 21. Because the silica gel balls 20 are eccentrically arranged and the eccentric phase angles of the adjacent silica gel balls 20 are different, when the connecting rotating shaft 21 rotates synchronously, the massage surface formed by the silica gel balls 20 can generate fluctuation change, thereby massaging the back of the patient.

In this embodiment, the first motor 6, the lifting cylinder 19 and the second motor 23 are controlled by switches arranged on the bed head, so that the patient can conveniently adjust and start the massage without assistance of outsiders.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
