Technical Field
[0001] The utility model relates to the technical field of training equipment, in particular to a pull-up training device. Background Art
[0002] When people need to train pull-ups, they usually hold the horizontal bar with both hands, hang their bodies in the air, swing their bodies, use the force of the swinging body to stop suddenly, pull the bar up with both hands, raise their chins above the bar surface, slowly bend their arms when getting off the bar, slowly return their bodies to the starting state, then bend their knees, and use the force to complete the next movement. Pull-ups require people's arms to have great strength. When training pull-ups, people directly hold the horizontal bar with both hands. Because the bar is hard and smooth, people's palms will be very painful after training pull-ups. Moreover, the current horizontal bars are generally fixed and cannot be adjusted according to height. For people who are too tall or too short, a horizontal bar of another height needs to be built to train pull-ups normally.
[0003] However, in the prior art, for example, China Publication No.: CN104587641A, "A pull-up training device", the present invention discloses a pull-up training device, comprising a base and a support rod arranged on the base, a U-shaped connecting rod is arranged at the top of the support rod, and training handles are respectively connected to both ends of the U-shaped connecting rod; the training handles are composed of a connecting plate connected to the U-shaped connecting rod and a handle connected to the edge of the connecting plate, and the handle is composed of a U-shaped part connected to the connecting plate and a rod part connected to the U-shaped part; the pull-up training device automatically forces the trainee to separate his arms and exert force when the trainee exerts force upward during training, so as to ensure that the trainee exerts force at a correct angle; in this way, the trainee's force is much less than that of the existing device, and the actual training difficulty can be greatly reduced, which is not only conducive to improving the interest of the exercisers, but also beneficial to improving the utilization rate of such facilities.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] See also Figure 1-5 The utility model provides a technical solution: a pull-up training device, comprising two hollow rods 2, the outer surface of the hollow rod 2 is movably sleeved with a rod sleeve 3, the inner surface of the rod sleeve 3 is fixedly connected with a transmission plate 4, the inner surface of the transmission plate 4 is rotatably connected with a threaded rod 5, the outer surface of the threaded rod 5 is threadedly connected with an internal threaded sleeve 6, the outer surface of the internal threaded sleeve 6 is fixedly connected with four connecting plates 7, the side of the connecting plate 7 away from the internal threaded sleeve 6 is fixedly connected to the inner surface of the hollow rod 2, the top of the threaded rod 5 is fixedly connected with a driven bevel gear 8, the rod The sleeve 3 is internally rotatably connected with an output rod 9 and extends one end. The outer surface of the output rod 9 is fixedly sleeved with a driving bevel gear 10. The outer surface of the driving bevel gear 10 is meshingly connected to the outer surface of the driven bevel gear 8. One end of the output rod 9 that extends is fixedly connected with a rocker arm 11. The rotating driving bevel gear 10 will drive the driven bevel gear 8 and the threaded rod 5 to rotate around the axis of the threaded rod 5 under the action of meshing. The threaded rod 5 is rotatably connected inside the transmission plate 4, and the rotating thread will cause the threaded rod 5 to move up and down inside the internal threaded sleeve 6.
[0026] like Figure 1-5 As shown, a flange plate 1 is fixedly connected to the bottom of the hollow rod 2, and a pressure beam 12 is fixedly connected to the top of the two rod sleeves 3. The two flange plates 1 can be used to fix the device at the target position.
[0027] like Figure 1-5 As shown, two semicircular plates 13 are fixedly connected to one side of the pressure beam 12 , and a plurality of first adjustment slots 14 are formed on the semicircular plates 13 . The first adjustment slots 14 corresponding to the semicircular plates 13 can be used to fix the rotation angle of the adjustment plate 15 .
[0028] like Figure 1-5 As shown, two adjusting plates 15 are rotatably connected to the bottom of the pressure beam 12 . The adjusting plates 15 are provided with second adjusting grooves 16 for assembling the bolts 17 and the adjusting plates 15 .
[0029] like Figure 1-5As shown, the inner surface of the second adjustment groove 16 is threadedly connected with a bolt 17, and the outer surface of the bolt 17 near the bottom is threadedly connected to the inner surface of the first adjustment groove 14. The bolt 17 is rotated and assembled into the inside of the second adjustment groove 16 of the adjustment plate 15 and the inside of the corresponding first adjustment groove 14 on the semicircular plate 13. After the assembly is completed, the distance between the two adjustment plates 15 away from the end of the pressure beam 12 will be fixed.
[0030] like Figure 1-5 As shown, the top of the pressure beam 12 is rotatably connected to two reinforcing plates 18, the bottom of the reinforcing plates 18 is fixedly connected to a connecting rod 19, and the bottom of the connecting rod 19 is fixedly connected to the top of the adjusting plate 15. The reinforcing plates 18 make the ultimate load-bearing capacity of the adjusting plate 15 higher and can adapt to a larger weight.
[0031] like Figure 1-5 As shown, the bottom of the reinforcing plate 18 is rotatably connected to a rotating shaft 20, and the outer surface of the rotating shaft 20 is rotatably connected to the inside of the adjusting plate 15 and extends one end downward, and the rotating shaft 20 can drive the handle 22 to rotate.
[0032] like Figure 1-5 As shown, one end of the rotating shaft 20 extending downward is fixedly connected to a U-shaped plate 21, and the inner side of the U-shaped plate 21 is fixedly connected to a handle 22. Because the rotating shaft 20 can be rotated at will, the handle 22 can be rotated and adjusted, and the forehand, backhand and other angles can be grasped on the handle 22.
[0033] Working principle: First, use two flange plates 1 to fix the device at the target position. When the height of the device needs to be adjusted, the rockers 11 on both sides can be rotated to drive the output rod 9 to rotate inside the rod sleeve 3. The active bevel gear 10 that follows the rotation will drive the driven bevel gear 8 and the threaded rod 5 under the action of meshing to rotate around the axis of the threaded rod 5. The threaded rod 5 is connected and rotated inside the transmission plate 4. The rotating thread will cause the threaded rod 5 to move up and down inside the internal threaded sleeve 6, and drive the rotationally connected transmission plate 4 and the rod sleeve 3 to move up and down together. The up and down movement of the two rod sleeves 3 will drive the top pressure beam 12 and its assembly parts to move up and down together, thereby realizing the adjustment of the height of the device. The internal threaded sleeve 6 is fixed to the inner surface of the hollow rod 2 through the connecting plate 7. When the pull-up needs to be adjusted, the grip distance of the two hands can be reversed. Rotate the two adjustment plates 15. When the two adjustment plates 15 are at a suitable distance away from one end of the pressure beam 12, rotate the bolt 17 to assemble it into the second adjustment slot 16 of the adjustment plate 15 and the corresponding first adjustment slot 14 on the semicircular plate 13. After the assembly is completed, the distance between the two adjustment plates 15 away from the end of the pressure beam 12 will be fixed, and the grip distance will also be fixed. The reinforcing plate 18 rotatably connected to the top of the pressure beam 12 is fixed above the adjustment plate 15 by the connecting rod 19, so that the maximum load-bearing capacity of the adjustment plate 15 is higher and can adapt to a larger weight. Because the U-shaped plate 21 on the outside of the grip 22 is connected to the bottom of the shaft 20, and because the shaft 20 can be rotated at will, the grip 22 can be rotated and adjusted, and the forehand, backhand and other angles can be grasped on the grip 22.
