A mounting hole is horizontally opened at the bottom of the connecting block 10, and the mounting hole is connected to the receiving groove.

[0030] An engaging block 17 is slidably installed in the receiving groove, and the top of the engaging block 17 is an arc-shaped surface with an internal thread on the arc-shaped surface. A motor 7 is fixedly installed on one side of the box body 4, and the output end of the motor 7 extends into the box body 4 and is fixedly installed with a threaded rod 12, which is arranged horizontally. The threaded rod 12 passes through the through hole of the connecting block 10, and the external thread on the outer surface of the threaded rod 12 is threadedly installed with the internal thread on the top of the engaging block 17. An optical axis 15 is fixedly installed in the box body 4, and the optical axis 15 is arranged parallel to the threaded rod 12. The optical axis 15 passes through the other side of the connecting block 10 and is slidably installed with the connecting block 10.

[0031] A sliding assembly is installed on the connecting block 10, and an electric push rod 18 is fixedly installed horizontally on one side of the box body 4. The electric push rod 18 cooperates with the sliding assembly and drives the engagement block 17 to disengage from the threaded rod 12. The sliding assembly includes a fixed block 22, which is fixedly installed in the mounting hole, and a sliding rod 16 is horizontally installed on the fixed block 22. The sliding rod 16 passes through the fixed block 22 and is slidably installed with the fixed block 22.

[0032] The slide bar 16 includes a cross bar, a baffle is fixedly installed at one end of the cross bar away from the engagement block 17, a first spring 21 is fixedly installed between the baffle and the fixed plate, and a connecting rod 23 is hingedly installed at one end of the cross bar close to the engagement block 17.

A breathable cloth 2 is also installed on the top of the bed body 1, and the breathable cloth 2 is covered above the massage head 5.

[0035] A first transmission assembly for driving the massage head 5 to rotate is installed on the connecting block 10. The first transmission assembly includes a second gear 9 and two first gears 8. The second gear 9 and the two first gears 8 are both rotatably installed on the top of the connecting block 10. The second gear 9 is located between the two first gears 8. The two first gears 8 are arranged radially symmetrically about the second gear 9, and the two first gears 8 are both meshed with the second gear 9.

[0036] The two first gears 8 are coaxially mounted with the corresponding massage heads 5 , and a rack 11 is fixedly mounted on one side of the box body 4 . The rack 11 is parallel to the optical axis 15 , and meshes with one of the first gears 8 .

[0037] The second transmission assembly is installed in the box body 4. After the engagement block 17 is separated from the threaded rod 12, the second transmission assembly cooperates with the threaded rod 12 and drives the massage head 5 to rotate. The second transmission assembly includes a connecting rod 19, which is horizontally fixedly installed on the side of the box body 4 away from the motor 7. The top of the connecting rod 19 is rotatably installed with a third gear 13, and the third gear 13 cooperates with one of the first gears 8. The third gear 13 is coaxially fixedly installed with a second bevel gear 20, and the end of the threaded rod 12 close to the connecting rod 19 is fixedly sleeved with a first bevel gear 14, and the first bevel gear 14 is meshed with the second bevel gear 20.

[0038] The working principle of a cervical vertebra physiotherapy device provided in this embodiment is as follows:

[0039] When in use, the patient lies on the bed 1, with the patient's neck located above the breathable net 2. The motor 7 is started, and the motor 7 drives the threaded rod 12 to rotate. Since the threaded rod 12 is engaged with the internal thread at the top of the engagement block 17, the threaded rod 12 rotates and drives the connecting block 10 to move toward the third gear 13. At the same time, the connecting block 10 slides on the optical axis 15 and drives the first gears 8 to move. One of the first gears 8 is engaged with the rack 11, and one of the first gears 8 rotates when moving along the rack 11. One of the first gears 8 drives the second gear 9 to rotate, and the second gear 9 drives the other first gear 8 to rotate. Therefore, the two first gears 8 rotate and drive the corresponding massage heads 5 to rotate, and the massage heads 5 rotate to massage the patient's neck.

[0040] By making the output shaft of the motor 7 rotate forward and reverse, the massage head 5 can be driven to move back and forth along the corresponding opening slot 6, so that a wide range of physical therapy for the neck can be achieved.

[0041] When it is necessary to perform focused physical therapy on a diseased area of ​​the patient's cervical spine, the motor 7 is started to drive the connecting block 10 to move toward the third gear 13 through the threaded rod 12, and one of the first gears 8 is meshed with the third gear 13, and then the motor 7 is turned off and the threaded rod 12 stops rotating.

[0042] At this time, the slider 16 is close to the output end of the electric push rod 18, and the electric push rod 18 is started to push the slider 16 toward the engagement block 17. The slider 16 drives the engagement block 17 to move downward through the connecting rod 23, and the engagement block 17 is disengaged from the threaded rod 12, so that the threaded rod 12 will no longer drive the connection block 10 to move when it rotates. At the same time, the bottom of the engagement block 17 will squeeze the bottom of the box body 4 and limit the connection block 10 to prevent the connection block 10 from moving.

[0043] Then the motor 7 is started, the motor 7 drives the threaded rod 12 to rotate, the threaded rod 12 rotates and drives the first bevel gear 14 to rotate, the first bevel gear 14 drives the second bevel gear 20 to rotate, the second bevel gear 20 drives the third gear 13 to rotate, the third gear 13 drives one of the first gears 8 to rotate, so that the two first gears 8 rotate and drive the corresponding massage heads 5 to rotate, and the massage heads 5 rotate to massage the patient's neck, thereby achieving focused physical therapy for a diseased position of the patient's cervical spine.

[0044] Embodiment 2

[0045] See also Figure 9-10 The utility model provides a technical solution: a cervical vertebrae physiotherapy device. On the basis of the first embodiment, a sleeve 24 is coaxially fixedly installed on the top of the first gear 8, and the sleeve 24 is slidably fitted with the bottom of the massage head 5. A second spring 25 is installed in the sleeve 24, and one end of the second spring 25 is fixedly fitted with the first gear 8, and the other end of the second spring 25 is fixedly connected to the massage head 5.

[0046] A limit fitting is provided between the bottom of the massage head 5 and the sleeve 24, and the limit fitting includes a limit strip and a limit groove, the limit strip is fixedly installed at the bottom of the massage head 5, the limit groove is provided on the inner wall of the sleeve 24, and the limit strip and the limit groove are slidably installed. The limit fitting can prevent the massage head 5 and the sleeve 24 from rotating relative to each other, and can also enable the bottom of the massage head 5 to move up and down along the sleeve 24.

[0047] The working principle of a cervical vertebra physiotherapy device provided in this embodiment is as follows:

[0048] During the massage process of the massage block 5, since the force is generated between the massage head 5 and the patient's neck, the second spring 25 is buffered by the squeezing force of the massage head 5. This improves the comfort of the massage, reduces the discomfort of the patient, and further increases the therapeutic effect.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
