Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an outdoor abdominal muscle training device. Background Technology

[0002] The outdoor abdominal muscle trainer is a device specifically designed for outdoor fitness, aiming to help users strengthen their abdominal muscles through crunches. With increasing health awareness and the growing popularity of outdoor fitness activities, abdominal muscle trainers have gradually become common fitness equipment in parks, squares, and other public places. This type of equipment typically needs to possess good stability and durability to withstand the various challenges of the outdoor environment, while also meeting the needs of different users and providing effective exercise results.

[0003] Traditional outdoor abdominal training equipment often employs a relatively fixed mechanical structure design. Commonly, it consists of a simple, rigid frame assembled with fixed crossbars, supports, and other components. Its technical principle is usually based on human body weight; the user sits or lies on the machine, relying on their own body's lifting and curling movements, using gravity to help the body overcome resistance and stimulate the abdominal muscles. For example, some older sit-up benches only provide a basic lying support surface; the exerciser relies solely on their own strength to repeatedly sit up and lie down, without any additional adjustable assist or resistance components.

[0004] Existing outdoor abdominal trainers suffer from inconsistent resistance levels due to varying muscle strength and fitness levels among users. For weaker users, excessive resistance leads to difficulty and even injury; conversely, for stronger or more experienced users, insufficient resistance results in ineffective training. This lack of personalized adjustment limits the applicability and practicality of abdominal trainers, preventing some users from achieving optimal training experience and results. Therefore, this outdoor support-style abdominal trainer is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an outdoor abdominal muscle training device, which aims to improve the problem that the existing technology cannot adjust the crunch intensity, resulting in reduced training effect for people of different strengths during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An outdoor abdominal muscle training device includes a base, a first fixed column fixedly connected to the top of the base, a second fixed column fixedly connected to the top of the base, a hollow block fixedly connected to the top of the second fixed column, a first connecting column fixedly connected to the top of the hollow block, a second connecting column fixedly connected to the outer wall of the first connecting column, and an adjustment component provided inside the hollow block.

[0008] The adjustment assembly includes a first turntable, the outer wall of which is rotatably connected to the interior of a hollow block. A first threaded rod is fixedly connected to one end of the first turntable, a connecting plate is fixedly connected to the side wall of the first threaded rod, a retaining ring is fixedly connected to the outer wall of the connecting plate, a first spring is provided on the outside of the retaining ring, one end of the first spring is fixedly connected to the outer wall of the retaining ring, a support plate is fixedly connected to the other end of the first spring, a sliding plate is fixedly connected to the top of the support plate, and the sliding plate is slidably connected to the outer wall of a second connecting column. A handrail assembly is provided on the side wall of the second connecting column.

[0009] As a further description of the above technical solution:

[0010] The handrail assembly includes a fixing plate, the bottom of which is fixedly connected to the top of a second connecting column, a padded handrail is fixedly connected to the top of the fixing plate, and the bottom of the fixing plate is fixedly connected to the top of a first fixing column;

[0011] As a further description of the above technical solution:

[0012] A connecting block is provided on the top of the base, and a hollow column is provided inside the connecting block;

[0013] As a further description of the above technical solution:

[0014] A third fixed column is slidably connected inside the hollow column, and a button is fixedly connected inside the third fixed column;

[0015] As a further description of the above technical solution:

[0016] The outer wall of the third fixed column is slidably connected to the inside of the hollow column, and a second spring is provided at the bottom of the third fixed column, with one end of the second spring fixedly connected to the bottom of the third fixed column;

[0017] As a further description of the above technical solution:

[0018] The other end of the second spring is fixedly connected to the inside of the hollow column, and the other end of the button is fixedly connected to a trapezoidal column;

[0019] As a further description of the above technical solution:

[0020] A retaining ball is provided at the top of the trapezoidal column, and the outer wall of the retaining ball is located inside the base.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by rotating the first turntable, the first turntable drives the first threaded rod to move, the first threaded rod moves the connecting plate to move, and the retaining ring moves. The retaining ring causes the first spring to contract, which in turn moves the support plate. The support plate then moves the sliding plate to slide on the outer wall of the second connecting column, thus achieving the effect of adjusting the abdominal crunch intensity. This solves the problem that the inability to adjust the abdominal crunch intensity leads to a decrease in the training effect for people of different strengths during use, and improves the practicality of the abdominal muscle trainer.

[0023] 2. In this utility model, pressing the button moves the trapezoidal column at the bottom, and the ball releases force, causing it to move into the interior of the hollow column, achieving the effect of quick disassembly. This solves the problem of insufficient disassembly, which leads to excessive waste of space when not in use, and improves the convenience of the abdominal muscle trainer.

[0031] 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.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an outdoor abdominal muscle training device, including a base 1. The base 1 is made of high-strength steel to ensure the stability and durability of the device. A first fixed column 3 is fixedly connected to the top of the base 1, a second fixed column 4 is fixedly connected to the top of the base 1, a hollow block 5 is fixedly connected to the top of the second fixed column 4, a first connecting column 13 is fixedly connected to the top of the hollow block 5, and a second connecting column 14 is fixedly connected to the outer wall of the first connecting column 13. The first connecting column 13 and the second connecting column 14 are also usually made of high-strength steel to ensure the firmness and stability of the connection. An adjustment component is provided inside the hollow block 5.

[0033] The adjustment assembly includes a first turntable 6, whose outer wall is rotatably connected to the interior of a hollow block 5. A first threaded rod 7 is fixedly connected to one end of the first turntable 6, and a connecting plate 8 is fixedly connected to the side wall of the first threaded rod 7. A retaining ring 9 is fixedly connected to the outer wall of the connecting plate 8. The connecting plate 8 and the retaining ring 9 can be made of high-strength plastic or aluminum alloy to ensure their stability and durability during adjustment. A first spring 10 is provided on the outer side of the retaining ring 9, with one end fixedly connected to the outer wall of the retaining ring 9 and the other end fixedly connected to a support plate 11. A sliding plate 12 is fixedly connected to the top of the support plate 11. The support plate 11 and the sliding plate 12 are typically made of high-strength plastic or aluminum alloy to reduce weight and improve the smoothness of sliding. The sliding plate 12 is internally slidably connected to the outer wall of the second connecting column 14. The side wall of the second connecting column 14 is provided with a handrail assembly, which includes a fixed plate 22. The bottom of the fixed plate 22 is fixedly connected to the top of the second connecting column 14, and the top of the fixed plate 22 is fixedly connected to a padded handrail 15. The padded handrail 15 is made of thermoplastic composite material, which has good anti-slip and wear resistance, while providing a comfortable grip. The bottom of the fixed plate 22 is fixedly connected to the top of the first fixed column 3.

[0034] Specifically, when using the abdominal muscle trainer, the user first needs to kneel on top of the sliding plate 12 to ensure stability and comfort. Next, the user grips the outer wall of the soft-padded armrests 15 for good support and a good grip during the crunch exercise. As the crunch continues, the sliding plate 12 slides along the outer wall of the second connecting column 14, providing a smooth exercise experience. To adjust the crunch intensity, the user can rotate the first turntable 6. When the user applies force, the first turntable 6 moves the first threaded rod 7. The movement of the first threaded rod 7 further moves the connecting plate 8, which in turn moves the retaining ring 9 on its outer wall. The movement of the retaining ring 9 causes the first spring 10 to contract, and during this contraction, the first spring 10 transmits force to the support plate 11. Finally, the support plate 11 transmits the increased tension to the sliding plate 12, thus effectively adjusting the crunch intensity. With this design, the abdominal muscle trainer can flexibly adjust the training intensity according to the user's needs and physical condition, helping users to better train their abdominal muscles and achieve ideal fitness results.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The base 1 has a connecting block 2 on its top. Both the base 1 and connecting block 2 are typically made of high-strength aluminum alloy, which is lightweight, corrosion-resistant, and high-strength, effectively supporting the overall structure and extending its service life. The connecting block 2 contains a hollow column 16, typically made of stainless steel, which has high hardness, wear resistance, and oxidation resistance. A third fixing column 19 is slidably connected inside the hollow column 16. A button 17 is fixedly connected inside the third fixing column 19. The button 17 is made of engineering plastic, possessing wear resistance, self-lubrication, and good mechanical strength. The third fixing column 1... The outer wall of the 9 is slidably connected to the inside of the hollow column 16. The bottom of the third fixed column 19 is provided with a second spring 20. One end of the second spring 20 is fixedly connected to the bottom of the third fixed column 19, and the other end of the second spring 20 is fixedly connected to the inside of the hollow column 16. The other end of the button 17 is fixedly connected to a trapezoidal column 18. The top of the trapezoidal column 18 is provided with a retaining ball 21. The trapezoidal column 18 and the retaining ball 21 are made of quenched steel, which has extremely high hardness and wear resistance and can withstand large pressure and friction, ensuring that the retaining ball 21 maintains a stable fixing effect when moving inside the base 1. The outer wall of the retaining ball 21 is set inside the base 1.

[0036] Specifically, when disassembling the device, first press button 17. Upon application of force, button 17 will move its bottom trapezoidal column 18, causing it to slide linearly along the interior of the hollow column 16. During this movement, the outer wall of the trapezoidal column 18 will contact the retaining ball 21, releasing it from its original fixed position and moving it into the interior of the hollow column 16. Simultaneously, the third fixing column 19 on the outer wall of button 17 will also be moved, sliding linearly along the inner wall of the hollow column 16. During this movement, the third fixing column 19 will cause its bottom second spring 20 to contract. During installation, first insert the hollow column 16 into the connecting block 2, placing the bottom of the hollow column 16 inside the base 1. At this time, the retaining ball 21 will be compressed by external pressure, moving it into the interior of the hollow column 16. Next, through the elastic force of the second spring 20, the trapezoidal column 18 will be pressed against the outer wall of the locking ball 21, thereby fixing the locking ball 21 inside the hollow column 16, achieving the effect of quick disassembly and installation.

[0037] Working principle: When using the abdominal muscle trainer, the user first kneels on top of the sliding plate 12, then grasps the outer wall of the soft handrail 15 with both hands and performs a crunch. This causes the sliding plate 12 to slide along the outer wall of the second connecting column 14. Then, by rotating the first turntable 6, the first turntable 6 is forced to move the first threaded rod 7. The movement of the first threaded rod 7 moves the connecting plate 8, which in turn moves the retaining ring 9 on the outer wall. After the retaining ring 9 moves, it causes the first spring 10 to contract. When the first spring 10 contracts, it also drives the support plate 11 with force, which in turn transmits the increased tension to the sliding plate 12, thus achieving the effect of adjusting the crunch intensity.

[0038] During disassembly, first press button 17. Button 17 will be forced to slide the trapezoidal column 18 at the bottom inside the hollow column 16. During the movement of the trapezoidal column 18, the outer wall of the locking ball 21 will be released, moving it into the hollow column 16. In this process, the third fixing column 19 on the outer wall of button 17 will be moved to slide into the hollow column 16. During the movement of the third fixing column 19, the second spring 20 at the bottom will be compressed. During installation, the hollow column 16 is inserted into the connecting block 2, and the bottom of the hollow column 16 is placed inside the base 1. Then, the locking ball 21 will compress it, moving it into the hollow column 16. The elastic force of the second spring 20 will press the trapezoidal column 18 against the outer wall of the locking ball 21, achieving the effect of quick disassembly.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
