Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a structure for a portable flat treadmill. Background Technology

[0002] A flat treadmill is a common type of fitness equipment, mainly composed of a running platform, motor, controller, and display screen. The running platform is the platform for running, generally with a certain length and width, and a non-slip surface; the motor provides power to drive the running belt; the controller is used to adjust parameters such as the treadmill's speed and incline; and the display screen shows exercise data such as speed, distance, time, and calories burned.

[0003] Traditional treadmills are generally large and heavy, making them inconvenient to move and adjust. Some treadmills are equipped with casters, but these are usually only located at the front. To move them, the treadmill needs to be stood up, and the casters at the front are used for movement. Standing up the treadmill often requires a lot of force, making it still inconvenient to move. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a convenient and portable flat treadmill structure.

[0005] This utility model is achieved by the following technical solution: a conveniently movable flat treadmill structure, including a flat treadmill body, an extension rod fixedly connected to the bottom of the flat treadmill body, four extension rods, and universal wheels fixedly connected to the bottom of each of the four extension rods; lifting components are provided at both ends of the flat treadmill body, and a drive component is provided at the right end of the lifting components.

[0006] The lifting assembly includes a mounting frame, the inner wall of which is rotatably connected to a two-way lead screw, the surface of which is threadedly connected to a sliding seat, the bottom of which is fixedly connected to a first hinge seat, the inner wall of which is hinged to a movable plate, the end of which is away from the first hinge seat is hinged to a second hinge seat, and the bottom of which is fixedly connected to a base plate.

[0007] The above technical solution increases the height of the casters by extending the rod, making it easier to store the lifting assembly at the bottom of the treadmill body. The casters facilitate overall movement. When the two bidirectional lead screws rotate, the sliding seats are threadedly connected to the bidirectional lead screws, causing the two adjacent sliding seats to move closer to each other. At the same time, the movable plate rotates on the inner walls of the first and second hinge seats, pushing the base plate downwards to contact the ground, lifting the treadmill body and suspending the casters in the air.

[0008] As a further improvement to the above solution, two mounting brackets are provided, with one end of each mounting bracket close to the other fixedly connected to the surface of the treadmill body.

[0009] As a further improvement to the above solution, the inner wall of the mounting bracket is provided with a sliding groove, and the surface of the sliding seat is slidably connected to the inner wall of the sliding groove.

[0010] The above technical solution limits the sliding seat by using a groove on the inner wall of the mounting frame, allowing the sliding seat to slide along the groove and preventing deviation during movement.

[0011] As a further improvement to the above scheme, the number of the sliding seat, the first hinge seat, the movable plate, and the second hinge seat are all provided to be four.

[0012] Through the above technical solution, the lifting assembly is subjected to uniform force when it is raised by four first hinge seats, a movable plate, and a second hinge seat, which can better support the treadmill body and improve the overall stability and reliability.

[0013] As a further improvement to the above solution, the drive assembly includes a mounting plate, a fixed rod rotatably connected to the inner wall of the mounting plate, a worm gear fixedly connected to the surface of the fixed rod, a worm wheel meshing with the inner wall of the worm gear, and a motor fixedly connected to one end of the mounting plate.

[0014] The above technical solution involves setting two mounting plates to support the fixed rod, ensuring stability during rotation. The motor drives the fixed rod to rotate, causing the two worm gears to rotate, which in turn drives the worm wheel to rotate, resulting in the rotation of the two bidirectional lead screws. This allows the lifting assembly to lift the flat treadmill body.

[0015] As a further improvement to the above solution, the top of the mounting plate is fixedly connected to the bottom of the mounting bracket, and the inner wall of the worm gear is fixedly connected to the surface of the bidirectional lead screw.

[0016] Through the above technical solution, and by utilizing the self-locking performance of the worm gear, when the worm stops rotating, the worm wheel cannot rotate in the opposite direction under the action of external force, thus ensuring that the fixed rod will not rotate unexpectedly due to external vibration or other factors after the lifting assembly completes the lifting action.

[0017] As a further improvement to the above solution, the output end of the motor is fixedly connected to one end of the fixing rod.

[0018] The above technical solution uses a mounting plate to install and fix the motor, ensuring its stability during use.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention features casters on the front and rear ends of the treadmill bottom, facilitating overall movement and improving ease of movement. Furthermore, by incorporating a lifting and driving assembly, the casters are suspended in the air during use, preventing the treadmill body from shifting and ensuring stability. Operation is simple and convenient. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figure 1-5 This embodiment provides a conveniently movable flat treadmill structure, including a flat treadmill body 1. An extension rod 2 is fixedly connected to the bottom of the flat treadmill body 1. The number of extension rods 2 is four. The bottom of each of the four extension rods 2 is fixedly connected to a universal wheel 3. Lifting components 4 are provided at both ends of the flat treadmill body 1. A drive component 5 is provided at the right end of the lifting component 4.

[0031] The lifting assembly 4 includes a mounting bracket 401. A double-acting lead screw 402 is rotatably connected to the inner wall of the mounting bracket 401. A sliding seat 403 is threaded onto the surface of the double-acting lead screw 402. A first hinge seat 404 is fixedly connected to the bottom of the sliding seat 403. A movable plate 405 is hinged to the inner wall of the first hinge seat 404. A second hinge seat 406 is hinged to the end of the movable plate 405 away from the first hinge seat 404. A base plate 407 is fixedly connected to the bottom of the second hinge seat 406. When it is necessary to adjust the position of the flat treadmill body 1, the casters 3 facilitate overall adjustment. The movable design improves the ease of movement and allows for flexible adjustment of the usage position. When the two bidirectional screws 402 rotate, the sliding seat 403 is threadedly connected to the bidirectional screw 402, causing the two adjacent sliding seats 403 to move closer to each other. At the same time, the movable plate 405 rotates on the inner wall of the first hinge seat 404 and the second hinge seat 406, pushing the base plate 407 downward to contact the ground, lifting the flat treadmill body 1 and suspending the casters 3 in the air. This prevents the flat treadmill body 1 from moving during use, ensuring stability during use and making operation simple and convenient.

[0032] There are two mounting brackets 401, and the ends of the two mounting brackets 401 that are close to each other are fixedly connected to the surface of the flat treadmill body 1.

[0033] The inner wall of the mounting bracket 401 is provided with a sliding groove, and the surface of the sliding seat 403 is slidably connected to the inner wall of the sliding groove.

[0034] The sliding seat 403, the first hinge seat 404, the movable plate 405, and the second hinge seat 406 are all provided in four quantities. The support stability during use is improved by using four first hinge seats 404, movable plates 405, and second hinge seats 406.

[0035] The drive assembly 5 includes a mounting plate 501. A fixed rod 502 is rotatably connected to the inner wall of the mounting plate 501. A worm gear 503 is fixedly connected to the surface of the fixed rod 502. A worm wheel 504 meshes with the inner wall of the worm gear 503. A motor 505 is fixedly connected to one end of the mounting plate 501. When the motor 505 is started, it drives the fixed rod 502 to rotate, causing the two worm gears 503 to rotate, which in turn drives the worm wheel 504 to rotate, thus causing the two bidirectional lead screws 402 to rotate.

[0036] The top of the mounting plate 501 is fixedly connected to the bottom of the mounting bracket 401, and the inner wall of the worm gear 504 is fixedly connected to the surface of the double-acting lead screw 402.

[0037] The output end of motor 505 is fixedly connected to one end of fixed rod 502.

[0038] The implementation principle of a conveniently movable flat treadmill structure in this embodiment is as follows: When the position of the flat treadmill body 1 needs to be adjusted, the casters 3 facilitate overall movement, improving the convenience of movement and allowing for flexible adjustment of the usage position. After adjustment, the motor 505 is started, which drives the fixed rod 502 to rotate, causing the two worm gears 503 to rotate, which in turn drives the worm wheel 504 to rotate, causing the two bidirectional lead screws 402 to rotate. Since the sliding seat 403 is threadedly connected to the bidirectional lead screw 402, the two adjacent sliding seats 403 move closer to each other. At the same time, the movable plate 405 rotates on the inner wall of the first hinge seat 404 and the second hinge seat 406, pushing the base plate 407 downward to contact the ground, lifting the flat treadmill body 1, and suspending the casters 3 in the air. This prevents the flat treadmill body 1 from moving during use, ensuring stability during use, and making operation simple and convenient.

[0039] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
