[0022] 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.
[0023] Example 1
[0024] like Figure 1-2 As shown, this embodiment provides an inertial training device, including a main support 1. The main support 1 is provided with several ground-mounted training modules, high-hanging training modules, and pull-up training modules. The ground-mounted training module includes a first inertial disc training mechanism; the high-hanging training module includes a second inertial disc training mechanism; and the pull-up training module includes a third inertial disc training mechanism. The first, second, and third inertial disc training mechanisms respectively include a first rotating shaft support 2, a second rotating shaft support 3, and a third rotating shaft support 4. The first rotating shaft support 2, the second rotating shaft support 3, and the third rotating shaft support 4 are all rotatably connected to horizontally distributed rotating shafts. One end of the rotating shaft is coaxially fixedly connected to a flywheel 5. A counterweight wheel sleeve 6 is coaxially fixedly fixed on the outer surface of the flywheel 5. Several counterweight wheels 11 are coaxially fixedly sleeved on the counterweight wheel sleeve 6. The counterweight wheel sleeve 6 is a screw rod, and a fixing nut 12 is screwed on the screw rod. The fixing nut 12 presses and fixes the counterweight wheels 11 and the flywheel 5.
[0025] The first rotating shaft support 2 is fixed to the bottom of the main support 1, and a fixed pulley assembly is provided directly above the first rotating shaft support 2. The fixed pulley assembly is detachably fixed to the main support 1. The fixed pulley assembly includes a pulley frame 7, which is detachably fixed to the main support 1. Several fixed pulleys 8 are rotatably connected to the pulley frame 7, and the rotating shafts of the fixed pulleys 8 are perpendicular to the rotating shaft in the first rotating shaft support 2. The pulley frame 7 is bolted to the main support 1, and the main support 1 has several equally spaced vertically distributed bolt holes.
[0026] The second rotating shaft bracket 3 is vertically rotatably connected to a base 9, which is detachably fixed to the main bracket 1. The base 9 and the main bracket 1 are connected by bolts, and the main bracket 1 has several equally spaced vertically distributed bolt holes.
[0027] Among them, the third rotating shaft support 4 is provided with a standing platform 10, and the top surface of the standing platform 10 is a horizontal standing surface.
[0028] The top of the main support 1 is equipped with several miscellaneous hooks 13.
[0029] In use, a training belt is wound and fixed around the axles of the first rotating shaft support 2, the second rotating shaft support 3, and the third rotating shaft support 4. The end of the training belt is then secured to the head or other body parts to bear the load. Pulling the training belt with the head or other body parts drives the flywheel 5 to rotate, thus utilizing the inertia generated during the rotation of the flywheel 5 to perform functional training of the deep small muscle groups in the waist and neck. When adjusting the training intensity, unscrew the fixing nut 12 on the counterweight wheel sleeve 6, place a counterweight wheel 11 of a certain weight onto the counterweight wheel sleeve 6, and tighten the fixing nut 12. This adjusts the rotational inertia of the flywheel 5, achieving a stronger muscle group functional training effect.
[0030] This embodiment features a floor-mounted training module, a hanging training module, and an upward-pull training module, offering a wide range of functions. The fixed pulley assembly in the floor-mounted training module, the second rotating shaft support 3 and base 9 in the hanging training module, which can rotate vertically, and the standing platform 10 in the upward-pull training module can flexibly adapt to users with various training needs and methods. Furthermore, the number of each module can be set to multiple, allowing multiple users to exercise simultaneously.
[0031] In this embodiment, the tensile force is generated by inertial work, and the muscles perform functional strength training and muscle activation training by eccentric contraction. The design is compact and occupies little space. The flywheel 5 can be equipped with a weighted wheel 11 according to training needs, so that the tensile force generated by the flywheel 5 can be flexibly adjusted according to the user's training needs to meet the training needs of different groups of people.
[0032] In this embodiment, there are two sets of floor-mounted training modules and two sets of hanging training modules, and one set of pull-up training modules, which can enable 5 people to train at the same time.
[0033] In this embodiment, the main support 1 has product specifications of ≤1800*1800*2500mm (length*width*height), ±10%, and is black or gray in color. The main tube is a square tube with specifications of 100*50*3mm.
[0034] In this embodiment, there are a total of thirteen counterweights 11, with counterweights 11 having weights of 3.65kg, 2.55kg, and 1.65kg.
[0035] Example 2
[0036] The difference between this embodiment and embodiment 1 is that the counterweight wheel 11 and the counterweight wheel sleeve 6, the pulley frame 7 and the main support 1, and the base 9 and the main support 1 are connected by a snap-fit structure. The counterweight wheel 11, the pulley frame 7 and the base 9 are provided with snap-fit protrusions, while the counterweight wheel sleeve 6 and the main support 1 are provided with corresponding snap-fit grooves. The snap-fit protrusions and snap-fit grooves are fixedly connected by snap-fit. In addition, there are multiple snap-fit grooves on the main support 1 that are vertically distributed at equal intervals to realize the height adjustment of the pulley frame 7 and the base 9 on the main support 1.
[0037] The other structures are the same as in Embodiment 1, and will not be described again here.
