[0029] Figure 6 It is a cross-sectional view of the high pull mechanism of a dumbbell rowing machine;

[0030] As Figures 1-6 shown, a dumbbell rowing machine of the present disclosure may include components such as a base mechanism and a high pull mechanism;

[0031] As Figures 1-6 shown, the base mechanism includes a main frame 1, a storage groove 2, an auxiliary frame 3, a card slot 4, a cavity 5, a limit plate 6, a card member 7, a return spring 8, and a support frame 9;

[0032] The storage groove 2 is opened at the end of the main frame 1. The auxiliary frame 3 is slidably arranged in the storage groove 2 and is adapted to it. Two groups of card slots 4 are opened on the side of the main frame 1 and communicated with the storage groove 2. A cavity 5 is opened inside the auxiliary frame 3 and is located between a set of two card slots 4 near the port of the storage groove 2. Two limiting plates 6 are slidably arranged in the cavity 5. A return spring 8 is arranged in the cavity 5 and is located between the two limiting plates 6. Two clamping members 7 are installed at the center of the side surfaces of the two limiting plates 6 and extend into the corresponding set of two card slots 4. A plurality of support frames 9 are installed on the lower surfaces of the main frame 1 and the auxiliary frame 3;

[0033] When a storage device is needed, press the two clamping members 7 inward to make them disengage from the two card slots 4 they are inserted into and enter the cavity 5 to release the fixation of the auxiliary frame 3. And the two mutually approaching clamping members 7 compress the return spring 8 through the limiting plates 6, and push the auxiliary frame 3 towards the storage groove 2 to make it enter the storage groove 2. The inner wall of the storage groove 2 is used to squeeze the two clamping members 7 until the two clamping members 7 are aligned with another set of card slots 4, and the return spring 8 rebounds to drive the two clamping members 7 to insert into the two aligned card slots 4 to fix the auxiliary frame 3, thereby shortening the overall length of this device, reducing the storage space of the device, facilitating the storage of the device. When unfolding, just pull the auxiliary frame 3 outward through the above operation to make the two clamping members 7 snap into a set of card slots 4 near the port of the storage groove 2;

[0034] As Figures 1-6 shown, the high-pull mechanism includes a U-shaped frame 10, a support plate 11, a telescopic damping rod 12, a buffer spring 13, a pulley 14, a hanging seat 15, a dumbbell 16, a steel wire 17, a pull rod 18, a positioning hole 19, a U-shaped seat 20, a screw rod 21, a knob 22, a seat 23, a pedal 24;

[0035] The U-shaped frame 10 is installed on the upper surface of the auxiliary frame 3. Two telescopic damping rods 12 are installed on the upper surface of the auxiliary frame 3 and are located between the inner walls of the U-shaped frame 10. The support plate 11 is installed at the upper ends of the two telescopic damping rods 12. Each buffer spring 13 is sleeved on the corresponding telescopic damping rod 12. Three pulleys 14 are rotatably installed in a triangular shape between the inner walls of the U-shaped frame 10. The hanging seat 15 is slidably arranged between the inner walls of the U-shaped frame 10 and is located directly above the support plate 11. A plurality of dumbbells 16 are hung on the side of the hanging seat 15. The steel wire 17 is installed on the upper surface of the hanging seat 15 and its end bypasses one of the upper pulleys 14, then bypasses the lower pulley 14 and then bypasses the other steel wire 17 above. The pull rod 18 is installed at the other end of the steel wire 17. Two positioning holes 19 are opened on both sides of the hanging seat 15. Two U-shaped seats 20 are installed on both sides of the U-shaped frame 10 and on one side of the positioning hole 19. A threaded hole aligned with the positioning hole 19 is opened on the side of each U-shaped seat 20 on the side of the positioning hole 19. Each threaded hole is provided with a screw rod 21 whose end extends into the positioning hole 19 on the same side. Each knob 22 is installed at the other end of the corresponding screw rod 21. The seat 23 is slidably arranged on the upper surface of the main frame 1. Two pedals 24 are installed on both sides of the auxiliary frame 3;

[0036] Before use, rotate the two knobs 22 to drive the two screws 21 to rotate. Through the threaded holes, the two screws 21 move away from each other, and the two screws 21 are removed from the two positioning holes 19 into which they are inserted, so that the fixing of the hanging seat 15 can be released. The user sits on the seat 23 and steps on the pedal 24. The user's legs are straightened and the seat 23 moves backward. And by pulling the pull rod 18 with both arms to move, the dumbbell 16 on the hanging seat 15 is pulled up by the steel wire 17. Then, the pulling force is reduced to let the hanging seat 15 descend. Then the user continues to pull the pull rod 18 to lift through the hanging seat 15 and the dumbbell 16. Repeating the lifting operation can exercise the body. When the hanging seat 15 descends and touches the support plate 11, it will squeeze the support plate 11 to make it descend. Then, while compressing the two telescopic damping rods 12, the two buffer springs 13 are compressed. The telescopic damping rods 12 and the buffer springs 13 are used to buffer the descending hanging seat 15, avoiding the hanging seat 15 directly hitting the auxiliary frame 3 and causing damage, and extending the service life of the device. When the use is completed, align the two positioning holes 19 of the hanging seat 15 with the two screws 21, and reverse the two screws 21 to make them snap into the two positioning holes 19 to fix the hanging seat 15;
