Description

Technical Field

[0001] This utility model relates to the field of fitness equipment, and in particular to a resistance adjustment device for a front kick training device. Background Technology

[0002] Front kick training can train the front leg muscles of fitness enthusiasts. Most existing front kick training machines use the method of adjusting the weight blocks to allow fitness enthusiasts to adjust the number of pounds. Simply put, the distance the resistance mechanism moves does not change, but the number of pounds of exercise changes.

[0003] Due to individual differences, some people have weak front kick strength, making it difficult to train with low-weight kicks directly. Moreover, people who have not trained their front kicks much have limited range of motion, and the resistance mechanism's large movement distance makes training very difficult for beginners. Existing equipment cannot meet this need. Therefore, based on the above description, this application proposes a resistance adjustment device for a front kick trainer. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a resistance adjustment device for a front kick training device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a resistance adjustment device for a front kick trainer, comprising a base, a column mounted on one side of the base, a connecting column mounted on the side of the column away from the base, a crossbar rotatably connected to the top of the column, the middle of the crossbar rotatably resting on the top of the column, a second force-bearing rod fixed to one end of the crossbar, a first force-bearing rod fixed to the other end of the crossbar, a slider slidably disposed within the first force-bearing rod, a spring connected to the bottom of the slider, the other end of the spring mounted on the top of the connecting column, a threaded rod threadedly connected to the slider, a worm gear fixedly connected to one end of the threaded rod, and a worm engaging with the worm.

[0006] As a further description of the above technical solution:

[0007] The first force-bearing rod and the second force-bearing rod are on the same plane and are located on the same side of the crossbar.

[0008] As a further description of the above technical solution:

[0009] A seat is provided on the top of the base, and a resistance roller is rotatably connected to the end of the second force-bearing rod away from the crossbar. The resistance roller is located on the front side of the seat.

[0010] As a further description of the above technical solution:

[0011] The seat has a backrest on the side away from the resistance roller.

[0012] As a further description of the above technical solution:

[0013] A through groove is provided below the first force-bearing rod, and the spring slides in the through groove.

[0014] As a further description of the above technical solution:

[0015] The threaded rod is rotatably connected inside the first force-bearing rod.

[0016] As a further description of the above technical solution:

[0017] The worm gear is rotatably connected inside the first force-bearing rod, and one end of the worm gear passes through the first force-bearing rod and extends to be fixedly connected to a handwheel.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, turning the handwheel causes the worm gear to drive the worm wheel, which in turn rotates the threaded rod. This causes the slider to move the spring a certain distance. At this time, the first force rod changes the rotation distance of the horizontal bar, which shortens or lengthens the pulling distance of the second force rod and the resistance rod. This allows beginners to perform small-amplitude front kick exercises during training, making the front kick exercise less difficult. The movement distance of the resistance mechanism can be adjusted arbitrarily, gradually increasing the resistance for healthy training. Attached Figure Description

[0025] 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.

[0026] Reference Figure 1-3 This utility model provides an embodiment of a resistance adjustment device for a front kick training device, comprising a base 1, a column 3 mounted on one side of the base 1, a connecting column 9 mounted on the side of the column 3 away from the base 1, a crossbar 4 rotatably connected to the top of the column 3, the middle of the crossbar 4 rotatably resting on the top of the column 3, a second force-bearing rod 7 fixed to one end of the crossbar 4, a first force-bearing rod 5 fixed to the other end of the crossbar 4, a slider 14 slidably disposed within the first force-bearing rod 5, a spring 6 connected to the bottom of the slider 14, the other end of the spring 6 mounted on the top of the connecting column 9, and the slider 14 being threaded. A threaded rod 15 is connected, and a worm gear 13 is fixedly connected to one end of the threaded rod 15. The worm gear 13 is meshed with a worm 12. Before training, turn the handwheel 11 to make the worm 12 drive the worm gear 13 to make the threaded rod 15 rotate, so that the slider 14 drives the spring 6 to move a certain distance. At this time, the first force rod 5 changes the rotation distance of the crossbar 4, and the pulling distance of the second force rod 7 and the resistance roller 8 becomes shorter or longer. This allows beginners to adjust the front kick training at will during training. The movement distance of the resistance mechanism can be adjusted arbitrarily, and the resistance training can be gradually increased.

[0027] The first force-bearing rod 5 and the second force-bearing rod 7 are on the same plane and are located on the same side of the crossbar 4. Being on the same side facilitates force application during training. A seat 10 is provided on the top of the base 1. The end of the second force-bearing rod 7 away from the crossbar 4 is rotatably connected to a resistance roller 8. The resistance roller 8 is located on the front side of the seat 10. Sitting on the seat 10 allows for resistance training by kicking forward using the resistance roller 8.

[0028] The seat 10 has a backrest 2 on the side away from the resistance roller 8, which allows the trainee to lie down.

[0029] A through groove 16 is provided below the first force-bearing rod 5. The spring 6 slides in the through groove 16. The through groove 16 is mainly used to accommodate the moving spring 6 so that it can move easily.

[0030] The threaded rod 15 is rotatably connected inside the first force-bearing rod 5, and the threaded rod 15 mainly drives the slider 14 to move.

[0031] The worm gear 12 is rotatably connected inside the first force-bearing rod 5. One end of the worm gear 12 passes through the first force-bearing rod 5 and is fixedly connected to a handwheel 11. The handwheel 11 drives the worm gear 12, causing the worm wheel 13 to drive the threaded rod 15 to rotate.

[0032] Working principle: Before training, turn the handwheel 11 to make the worm gear 12 drive the worm wheel 13 to rotate the threaded rod 15, which makes the slider 14 drive the spring 6 to move a certain distance. At this time, the first force rod 5 changes the rotation distance of the crossbar 4, which shortens or lengthens the pulling distance of the second force rod 7 and the resistance roller 8, so that the front kick training can be adjusted arbitrarily during training. The movement distance of the resistance mechanism can be adjusted arbitrarily, and the resistance training can be gradually increased. During training, the person sits on the seat 10 with their back against the backrest 2, and places their legs between the seat 10 and the resistance roller 8. Raise the legs and kick forward to achieve the front kick training.
