Technical Field
[0001] This utility model relates to the field of fitness equipment technology, specifically to an indoor fitness equipment for abdominal and lumbar exercises. Background Technology
[0002] With increasing health awareness, the demand for fitness equipment in homes and gyms is becoming increasingly diversified. Currently, abdominal and lower back exercise equipment on the market, such as traditional sit-up machines and inverted chair machines, generally suffer from the following problems: 1. Problem of limited functionality: Existing equipment is usually designed for a single purpose. For example, sit-up boards can only be used for abdominal crunches, and inversion machines can only be used for inverted traction. If users want to carry out comprehensive core and spinal maintenance training, they need to purchase multiple different machines, which has the problems of large footprint, high purchase cost, and inconvenience of use.
[0003] 2. Stability and comfort issues: Especially when performing difficult postures such as inversions, many machines have simple support structures, which pose a risk of instability, swaying, or tipping over. At the same time, back supports are mostly made of rigid materials or fixed structures, which cannot effectively distribute pressure and conform to the curves of the human body, resulting in discomfort during training and may even cause back compression pain.
[0004] 3. Insufficient adaptability: The resistance of existing equipment is usually fixed and not adjustable, which cannot meet the personalized training needs of users of different genders, ages and fitness levels. Beginners may find the resistance too high and difficult to complete the movements, while advanced users may find the resistance insufficient and the training effect reduced, thus limiting the scope of its applicable population.
[0005] 4. Convenience issues: Due to the integrated structural design, many large exercise machines are bulky and have huge packaging dimensions, which brings great inconvenience to warehousing, transportation, and home users' storage.
[0006] Therefore, those skilled in the art have provided an indoor fitness device for abdominal and lumbar exercises to address the problems mentioned in the background art. Utility Model Content
[0007] To solve the above-mentioned technical problems, this utility model provides an indoor fitness equipment for abdominal and lumbar exercises. It includes a bottom support mechanism, the upper end of which is rotatably connected to an exercise main body mechanism for exercising the abdomen and waist. The upper end of the exercise main body mechanism is detachably connected to a top telescopic mechanism whose height can be adjusted according to usage needs. Furthermore, the bottom support mechanism and the exercise main body mechanism are detachably connected to an elastic adjustment mechanism to increase exercise resistance.

[0009] Preferably, the main exercise mechanism includes an exercise frame and a hand support frame fixedly connected to the lower end of the exercise frame. Both ends of the hand support frame are fixedly fitted with anti-slip rubber sleeves. A nut sleeve is fixedly connected to one side of the upper end of the exercise frame, and a bolt is connected to the internal thread of the nut sleeve.
[0010] Preferably, two sets of rotating connecting frames are fixedly connected to one side of the main exercise frame, and the two sets of rotating connecting frames are rotatably connected to the outside of the rotating connecting seat.
[0011] Preferably, a second elastic adjustment connecting seat is fixedly connected to one side of the hand support frame, and the elastic adjustment mechanism is sleeved between the second elastic adjustment connecting seat and the first elastic adjustment connecting seat, and the elastic adjustment mechanism is symmetrically arranged on the outer sides of the second elastic adjustment connecting seat and the first elastic adjustment connecting seat.
[0012] Preferably, the front side of the main exercise frame is fixedly connected to multiple sets of back rolling support frames, and each set of back rolling support frames has a back rolling support column fixedly inserted inside, and both ends of each set of back rolling support columns are rotatably connected to a back rolling sponge tube.
[0013] Preferably, the top telescopic mechanism includes a top adjusting component, a top rotating frame fixedly connected to one side of the upper end of the top adjusting component, and a sponge headrest rotatably connected to the inside of the top rotating frame.

In addition, the first and second limiting rubber posts can effectively limit the range of motion, prevent excessive backward tilting, and provide passive safety protection.
[0018] 3. This patent innovatively adopts a flexibly adjustable elastic resistance system. By setting up first and second elastic adjustment connecting seats and using elastic strips as a detachable elastic adjustment mechanism, users can easily set different resistance levels by simply increasing or decreasing the number of rubber strips (e.g., 2, 4, or 6 strips). This design allows a single device to be adapted to different strength levels, from beginners to professional athletes, meeting the personalized training needs of different users and broadening the product's applicable population.
[0019] 4. The key components of this patent adopt a detachable structural design. In particular, the backrest support tube is designed to be detachable. When transportation or storage is required, it can be removed from the bottom support frame, thereby significantly reducing the overall packaging volume of the product. This solves the core pain point of difficult packaging and transportation of large fitness equipment, reduces logistics costs, and makes it easier for home users to store and store.
