[0028] The utility model provides a novel adjustable lumbar massage board, such as Figure 1 , 3 Shown, including

[0029] A bottom plate 10, a slide groove 11 is provided on the surface of the bottom plate 10, and a control cavity 12 connected to the slide groove 11 is provided in the bottom plate 10; an elastic arch plate 20, one end of the elastic arch plate 20 is rotatably connected to one end of the bottom plate 10, and a slide column 21 is provided at the other end of the elastic arch plate 20, and the slide column 21 is slidably connected to the slide groove 11; a positioning plate 30, which is slidably connected to the control cavity 12, one end of the positioning plate 30 is hinged to the slide column 21, and the positioning plate 30 can move with the change of the curvature of the elastic arch plate 20, and the positioning plate 30 is provided A plurality of positioning bosses 31; a positioning member 40 is arranged above the positioning plate 30, and a control member 50 is arranged above the positioning member 40, and the control member 50 is used to control the up and down movement of the positioning member 40. When in use, the user can use his own gravity to squeeze the elastic arch plate 20 downward. After squeezing into place, the user uses the control member 50 to move the positioning member 40 downward, so that the end of the positioning member 40 remains engaged with the positioning boss 31, thereby limiting the further deformation of the elastic arch plate 20. After the above operation is completed, the lumbar relaxation exercise can be performed.

[0030] In order to improve the positioning effect between the positioning member 40 and the positioning plate 30, the positioning boss 31 in this embodiment is a toothed boss, and a toothed groove 41 is provided at the end of the positioning member 40. This positioning structure can increase the number of teeth to increase the effective contact area of ​​the occlusion, thereby improving the positioning effect.

[0031] In one embodiment, if Figure 2 As shown, the control member 50 includes a control box 51, in which a first control magnet and a second control magnet with opposite magnetic poles are fixed. The control box 51 is slidably connected to the base plate 10, and an induction magnet is fixed to the positioning member 40. When the control box 51 moves, the upward and downward movement of the positioning member 40 is controlled by the interaction principle between the magnetic poles of the magnets.

[0032] To facilitate the setting of the control box 51, a positioning boss 31 is provided on the base plate 10, a guide groove 131 is provided on the side of the positioning boss 31, and a guide bar 511 is provided on the control box 51. The guide bar 511 is slidably connected in the guide groove 131, thereby ensuring that the moving direction of the control box 51 relative to the base plate 10 is stable.

[0033] Taking into account that the user may have his back to the product during use, it may be inconvenient to directly move the control box 51 by hand. In one embodiment, a control rod 52 is fixed to the control box 51, and an annular boss 14 is provided on the base plate 10. The other end of the control rod 52 is slidably connected to the annular boss 14, and the user can directly control the movement of the control box 51 through the control rod 52.

[0034] In order to increase the contact area between the product and the ground, the product is provided with anti-scratch edges 15 on both sides of the base plate 10, and stop blocks 16 are provided at both ends of the anti-scratch edges 15. The elastic arch plate 20 is arranged between the stop blocks 16. The stop blocks 16 ensure that the elastic arch plate 20 will not be separated from the base plate 10 when pressed down.

[0035] Since the deformation capacity of the elastic arch plate 20 itself is limited, in order to ensure that the elastic arch plate 20 can rebound smoothly after the positioning effect is removed, this product is provided with a connecting column 17 extending to the control cavity 12 on the base plate 10, and a connecting plate 22 is hinged on the sliding column 21, and the connecting plate 22 is located in the control cavity 12. A tightening spring 23 is provided in the control cavity 12, and the two ends of the tightening spring 23 are respectively fixed on the connecting column 17 and the connecting plate 22, and the elastic arch plate 20 is pulled to retract by the locking spring.

[0036] In this product, the control cavity 12 is located on the lower surface of the base plate 10, and a removable sealing plate 18 is provided on the control cavity 12. A guide groove 181 is provided on the sealing plate 18, and the positioning plate 30 is slidably connected to the guide groove 181. The sliding direction of the sealing plate 18 is ensured to be stable by the guide groove 181. During assembly, the components in the control cavity 12 can be assembled first, and then the control cavity 12 can be closed with the sealing plate 18, which facilitates the assembly of this product. At the same time, the sealing plate 18 can also prevent dust and the like from entering the control cavity 12, thereby extending the service life of the internal components.

[0037] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
