[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides an embodiment of an outdoor fitness sit-up board with massage function, including a sit-up board 1. A front support rod 14 is fixedly installed at one end of the sit-up board 1, and a rear support rod 15 is fixedly installed at the other end of the sit-up board 1 via a diagonal rod. Anti-slip sleeves 16 are fitted around the outer rings of the front support rod 14 and the rear support rod 15 to improve the grip of the device. A massage groove 2 is fixedly opened inside the sit-up board 1. A lifting frame is slidably installed inside the massage groove 2 via a power component. The lifting frame includes two supports 3, which are respectively movably fitted to the inner walls of the two sides of the massage groove 2. A connecting plate 6 is fixedly connected between the lower ends of the two supports 3. The supports 3 have a trapezoidal structure and the middle of the supports 3 is hollowed out.

[0028] Furthermore, the upper end of the support 3 is provided with three equally spaced bearings 4, and a massage wheel 5 is rotatably arranged between two corresponding bearings 4. Several massage balls are fixedly arranged on the outer ring of the massage wheel 5.

[0029] During use, the three massage rollers 5 allow the user to massage their back muscles while lying on the sit-up board 1, relieving muscle fatigue during prolonged exercise. Due to different body types, the required protrusion height of the massage rollers 5 on the sit-up board 1 varies. For overweight users, the massage rollers 5 should protrude higher on the sit-up board 1, while for thinner users, the protrusion height should be lower to achieve the optimal massage effect.

[0030] At this time, the installation of the power component drives the lifting frame to move inside the massage groove 2, thereby adjusting the protrusion height of the massage roller 5 on the sit-up board 1. This makes it suitable for users of different body types and solves the problem that existing outdoor fitness sit-up boards with massage functions cannot freely adjust the protrusion height of the massage roller 5 on the sit-up board 1 according to the user's body type, which reduces the practicality of outdoor fitness sit-up boards.

[0031] Furthermore, the power assembly includes a support plate 8, which is fixedly mounted on the lower surface of the sit-up board 1. There are two support plates 8, which are symmetrically distributed about the center line of the sit-up board 1. The support plates 8 are located in the middle of the side of the massage groove 2. A bidirectional lead screw 10 is rotatably mounted between the two support plates 8. A rotating disk 11 is fixedly mounted at both ends of the bidirectional lead screw 10. A grip is fixedly mounted on the side of the rotating disk 11. Two movable rings 12 are threadedly connected to the outer ring of the bidirectional lead screw 10, which are symmetrically distributed about the center line of the bidirectional lead screw 10. A first hinge seat is fixedly mounted on the surface of the movable ring 12. Two second hinge seats are fixedly mounted on the lower surface of the connecting plate 6, which are symmetrically distributed about the center line of the connecting plate 6. A rotating rod 13 is rotatably mounted between the corresponding first and second hinge seats.

[0032] Furthermore, a limiting groove 9 is fixedly provided inside the support plate 8, and a limiting rod 7 is fixedly provided on the side of the bracket 3. The end of the limiting rod 7 away from the bracket 3 extends into the interior of the limiting groove 9 and is adapted to the limiting groove 9.

[0033] Specifically, when the user lies on the sit-up board 1, if it is necessary to adjust the protrusion height of the massage rollers 5 on the sit-up board 1, the user can simultaneously rotate the two grips with both hands to drive the bidirectional lead screw 10 to rotate. Under the limitation of the limiting rod 7 and the limiting groove 9, the two movable rings 12 are moved closer or further apart. Through the installation of the rotating rod 13, the connecting plate 6 is moved up and down, and finally the lifting frame and the three massage rollers 5 are moved up and down, thereby quickly adjusting the protrusion height of the massage rollers 5 on the sit-up board 1 and improving the convenience of the device.

[0034] Furthermore, a footrest 17 is fixedly installed on the outer ring of the middle part of the front support rod 14, and two elastic ropes 18 are fixedly installed on the outer ring of the front support rod 14, which are symmetrically distributed about the center line of the front support rod 14. The other end of the elastic rope 18 is fixedly connected to a grip ring. When the user lies on the sit-up board 1, he / she can also hold the grip ring with both hands at the same time to do arm stretching exercises, exercise the arm muscles, and enrich the function of the outdoor fitness sit-up board with massage function.

[0035] Working principle: During use, the three massage rollers 5 massage the user's back muscles when lying on the sit-up board 1, relieving muscle fatigue during prolonged exercise. To adjust the height of the massage rollers 5 on the sit-up board 1, the two grips are rotated simultaneously with both hands, causing the bidirectional screw 10 to rotate. Under the limitation of the limiting rod 7 and the limiting groove 9, the two movable rings 12 move closer or further apart. Through the installation of the rotating rod 13, the connecting plate 6 moves up and down, and finally the lifting frame and the three massage rollers 5 move up and down, thereby quickly adjusting the height of the massage rollers 5 on the sit-up board 1 to suit users of different body types.

[0036] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
