Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and specifically to an adjustable multifunctional fitness device. Background Technology

[0002] Today, with increasing health awareness, fitness has become an important part of daily life. More and more people are choosing to exercise using fitness equipment to improve their physical fitness and maintain health. However, many fitness equipment pieces have limited functions or uses; for example, some equipment can only perform limited sliding, pushing, and pulling movements. For users who need high-intensity training or more comprehensive workouts, such equipment may not meet their needs.

[0003] For example, Chinese Utility Model Patent No. CN202520432401.8 discloses a multifunctional fitness device, comprising: a support base with two outwardly extending telescopic rods rotatably connected to its bottom; an elastic element between the two telescopic rods or between the telescopic rods and the support base to bring the two telescopic rods into a close-up state; a human body support part on the upper surface of the support base; two slides, each corresponding to one of the two telescopic rods; a control part on each slide; and a universal wheel at the bottom of each slide.

[0004] The user sits on the support seat with their feet placed on the two sliding seats. Under the action of the elastic element, the two telescopic rods move in an opening and closing motion, thereby performing leg opening and closing exercises. However, the elastic force of the elastic element is fixed and cannot be adjusted, so the force of opening and closing cannot be adjusted. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable multi-functional fitness device that solves the problem of existing elasticity not being adjustable by adjusting the components.

[0006] The objective of this invention is achieved as follows: An adjustable multifunctional fitness device includes a support base, with two connecting rods spaced apart at the bottom of the support base.

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-7As shown, an adjustable multi-functional fitness device includes a support base 1. Two connecting rods 2 are spaced apart at the bottom of the support base 1. A telescopic rod 3 is installed inside the connecting rod 2. One end of the telescopic rod 3 is connected to a sliding seat 4. An elastic rope 5 is connected between the sliding seat 4 and the connecting rod 2 to push the sliding seat 4 to move back and forth for exercise. The other end of the connecting rod 2 is provided with a gear part 6. The gear part 6 is rotatably installed in the support base 1 via a rotating shaft, which can push the sliding seat 4 to open and close inward and outward for exercise. A lead screw 7 is provided on one side of the gear part 6. One end of the lead screw 7 is connected to a rotating column 8. The rotating column 8 is connected to a reset component 9 for resetting. One end of the reset component 9 is provided with an adjustment component 10 for adjusting its rebound force. When the sliding seat 4 is pushed to rotate left and right, the gear parts 6 on both sides will push the lead screw 7 to move back and forth. Through the cooperation of the lead screw 7, the gear parts 6 on both sides can rotate synchronously, so that the rotation angle and speed of the sliding seats 4 on both sides are the same.

[0029] This invention, through the cooperative design of the lead screw and gear, can not only push the sliding seat 4 to move back and forth for exercise, but also push the sliding seat 4 to move left and right for exercise, providing multiple exercise modes and achieving different exercise effects. The rebound force of the reset component 9 can be adjusted by adjusting the adjustment component 10, thereby adjusting the magnitude of the opening and closing force to suit different fitness groups.

[0030] The bottom of the support base 1 is provided with mounting base 11 and mounting base 2 12 respectively. The two ends of the lead screw 7 are connected to rotating column 13 and rotating column 2 8 respectively. One end of rotating column 13 is rotatably set in mounting base 11, and one end of rotating column 2 8 passes through mounting base 2 12 and is connected to reset component 9. During the rotation and movement of the lead screw 7, it will drive the rotating column to move at the same time. The rotating columns on both sides provide stability and support for the movement of the lead screw.

[0031] The reset assembly 9 includes a limiting sleeve 15 disposed at one end of the rotating post 8, and a reset spring 16 abutting between the limiting sleeve 15 and the mounting base 12. (See details...) Figure 4 In actual use, when the sliding seat 4 is pushed to open and close left and right, the gear parts 6 on both sides will push the lead screw 7 to move back and forth. When the lead screw 7 moves, it will also drive the limit sleeve 15 to move and compress the return spring 16, making its elastic potential energy greater. Therefore, when the sliding seat 4 is pushed to open and close left and right, it is necessary to overcome the elastic force of the return spring 16, which adds a resistance to it, thereby improving the exercise effect.

[0032] The adjustment assembly 10 includes an adjustment knob 17 located at the end of the rotating column 8. The adjustment knob 17 is located outside the limiting sleeve 15. The limiting sleeve 15 is movably fitted around the outer periphery of the rotating column 8. In actual use, the front and rear positions can be adjusted by rotating the adjustment knob 17, and the limiting sleeve 15 can be pushed to compress or stretch the spring, thereby adjusting its rebound force to increase or decrease the load to suit different exercise groups.

[0033] A gasket 18 is provided between the adjustment knob 17 and the limiting sleeve 15 to effectively prevent the adjustment knob 17 from sliding.

[0034] The bottom of the support base 1 is provided with a limiting seat 19 and a limiting seat 20, respectively. The limiting seat 19 and the limiting seat 20 are located on the inner side of the two connecting rods 2. A connecting seat 21 is installed on the outer periphery of the connecting rod 2. The connecting seat 21 is connected to a limiting member 22. A limiting groove 23 is opened in the limiting seat 19 for the limiting member 22 to be engaged, so as to restrict the rotation of the connecting rod 2. In actual use, when only the forward and backward movement function of the sliding seat 4 is needed, and its left and right opening and closing function is not needed, the position of the connecting rod 2 can be fixed by connecting the limiting member 22 to prevent it from rotating.

[0035] See details Figure 5 The limiting member 22 is a cylindrical rod, and spherical clips 24 are formed at both ends of the cylindrical rod, making it easy and simple to assemble and disassemble the spherical clips 24 and the limiting groove 23.

[0036] See details Figure 7 The connecting seat 21 is rotatably sleeved on the outer periphery of the connecting rod 2. The limiting member 22 is an L-shaped snap-fit ​​block. The side of the limiting seat 19 is fitted with a limiting seat 33. A limiting groove 23 for the limiting member 22 to snap into is formed between the limiting seat 33 and the limiting seat 19. The side of the limiting seat 33 is formed with an "Ω"-shaped snap-fit ​​groove for the connecting rod 2 to snap into. This can achieve initial fixation between the two. By rotating the connecting seat 21, the L-shaped snap-fit ​​block can be snapped into the limiting groove 23, which can achieve further fixation between the two and prevent the connecting rod 2 from rotating.

[0037] A connecting seat 25 is installed on the outer periphery of the connecting rod 2, and a connecting seat 3 26 is installed on the outer periphery of the telescopic rod 3. An elastic rope 5 is detachably provided between the connecting seat 3 26 and the connecting seat 2 25. Different counterweight effects can be achieved by replacing the elastic rope 5 with different elastic forces.

[0038] The bottom of the support base 1 is provided with several support feet 28, and the first limiting seat 19 and the second limiting seat 20 can also be used as support feet. The bottom of the sliding seat 4 is provided with sliding wheels 29.

[0039] The upper surface of the support base 1 is provided with a plurality of grips 30 and grip rods 31, and the upper surface of the sliding base 4 is provided with grips 32.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
