Description

Technical Field

[0001] The utility model relates to the technical field of treadmills, in particular to a treadmill with adjustable slope. Background Art

[0002] In modern society, people are increasingly concerned about health and fitness. Running, as a simple and effective form of aerobic exercise, has become widely popular. However, outdoor running is restricted by factors such as weather and the environment, making indoor treadmills the preferred choice for many people. Traditional treadmills usually have a fixed running belt surface and cannot simulate different terrain slopes. In actual running, different slopes can bring different training effects and challenges. For example, increasing the slope can enhance leg strength and endurance, improve cardiopulmonary function, and also simulate outdoor sports such as mountain climbing. With the continuous advancement of technology, people's requirements for treadmill functions are also increasing. Treadmills with adjustable slope have emerged. They can meet the needs of users at different training stages and goals. By adjusting the slope, users can customize personalized running training plans based on their physical condition and fitness goals.

[0003] The structure of traditional straight-board treadmills cannot meet the user's needs because it cannot adjust the slope of the treadmill, thereby reducing the user's comfort. In addition, the fixed distance of the treadmill of a general straight-board treadmill is relatively long, which can easily cause the treadmill to deform after long-term use. In addition, the angle of the display screen on the treadmill is fixed and cannot be adjusted. Different users cannot more conveniently view the training parameters on the display screen from their best perspective.

[0004] Therefore, it is urgent to provide a treadmill with adjustable slope to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a treadmill with adjustable slope.

[0006] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a treadmill with adjustable slope, including a first connecting block and a second connecting block, the tops of the two first connecting blocks are fixedly connected to the limiting plate, the two first connecting blocks are slidably connected to one side of the limiting plate with a fixed sleeve, the bottoms of the two first connecting blocks are fixedly connected to a plurality of universal wheels, the other sides of the two first connecting blocks are fixedly connected to an installation box, a transmission assembly is installed at the bottom of the inner wall of the installation box, an angle adjustment assembly is installed between the inner walls of the two second connecting blocks, the opposite surfaces of the outer walls of the two second connecting blocks are fixedly connected to a seventh connecting rod, an operating table is fixedly connected between the tops of the two seventh connecting rods, two handles are fixedly connected to one side of the operating table, and a start button and a display screen are provided on the top of the operating table.

[0007] The utility model is further configured as follows: the distance between every two universal wheels is equal, and the bottom of each universal wheel and the bottom of the seventh connecting rod are in the same plane.

[0008] Through the above technical solution, when the distance between each two universal wheels is equal, the treadmill is subjected to more even force during movement. Whether moving forward, backward or turning, the support force in all directions is relatively consistent, which greatly improves the overall stability of the treadmill and reduces the risk of shaking or tilting due to uneven force.

[0009] The utility model is further configured as follows: the two fixing sleeves are respectively tightly fitted with the corresponding first connecting block and the outer wall of the limiting plate.

[0010] Through the above technical solution, when the fixing sleeve is tightly fitted with the first connecting block and the outer wall of the limiting plate, loosening between the various components during use of the treadmill can be effectively prevented, thereby ensuring the stability of the overall structure of the treadmill.

[0011] The utility model is further configured as follows: the transmission assembly includes a motor installed at the bottom of the inner wall of the installation box, the output end of the motor is fixedly connected to a driving wheel, the inner walls of the two first connecting blocks are each provided with two installation grooves, a rotating rod is rotatably connected between each two of the installation grooves, the outer walls of the two rotating rods are fixedly connected to a transmission wheel, the front end of the outer wall of one of the rotating rods is fixedly connected to a driven wheel, a belt is installed between the driving wheel and the driven wheel, and a synchronous belt is provided between the two transmission wheels.

[0012] Through the above technical solution, the motor is first started, so that the motor drives the driving wheel to rotate, and then the driving wheel drives the belt to rotate. At the same time, the belt drives the driven wheel to rotate synchronously, and then the driven wheel drives the corresponding rotating rod to rotate, and the rotating rod drives the corresponding transmission wheel to rotate. Then, the friction force of the synchronous belt drives the other transmission wheel to rotate synchronously along the outer wall of the corresponding rotating rod, thereby achieving the purpose of transmission.

[0013] The utility model is further configured as follows: the driving wheel and the driven wheel are both in the same plane, and the size of the driven wheel is larger than that of the driving wheel.

[0014] Through the above technical solution, when the driving wheel and the driven wheel are in the same plane, it can ensure that the belt maintains a stable tension distribution during operation. When using a treadmill, the transmission system needs to continuously transmit power from the motor to the synchronous belt. The same plane design can make the belt run smoothly between the two wheels, avoiding unstable phenomena such as deviation, twisting or jumping.

[0015] The utility model is further configured such that the outer walls of the two rotating rods are tightly fitted with the corresponding mounting grooves and the inner walls of the transmission wheel.

[0016] Through the above technical solution, the close fit makes the friction more uniform, and the power can be transmitted from the rotating rod to the transmission wheel more efficiently, thereby improving the transmission efficiency of the treadmill and reducing energy consumption.

[0018] Through the above technical solution, the hydraulic rod is first started, so that the hydraulic rod drives the fifth connecting rod to move to one side, and then the fifth connecting rod drives the two adjusting parts to rotate a certain angle, and then move upward. At the same time, the two adjusting parts will drive the fourth connecting rod to move upward, and then the fourth connecting rod will drive the two adjusting rods to rotate upward along the outer wall of the third connecting rod, and then the two adjusting rods will drive the corresponding first connecting block to move upward, thereby achieving the purpose of adjusting the slope.

[0019] The utility model is further configured as follows: the outer wall of one end of the hydraulic rod is tightly fitted with the inner walls of the two third connecting blocks, and the other end is rotatably connected to the outer wall of the fifth connecting rod.

[0020] Through the above technical solution, it can be ensured that during the operation of the treadmill, there will be no loosening or shaking between the hydraulic rod and the third connecting block. At the same time, the tightly fitting connection can effectively resist the effects of these forces, so that the hydraulic rod is always firmly connected to the third connecting block, providing a guarantee for the stable operation of the treadmill.

[0021] The utility model is further configured as follows: the tops of the two adjusting rods on one side close to the hydraulic rod are both rotatably connected to the corresponding sixth connecting rod.

[0022] Through the above technical solution, when the adjustment rod is rotationally connected to the sixth connecting rod, more angle options can be provided for the adjustment of the treadmill. When adjusting the slope or other functions of the treadmill, this rotational connection allows the adjustment rod to rotate freely within a certain range, thereby achieving more precise angle adjustment.

[0023] The utility model is further configured such that: the two handles are arranged in parallel with the operating table.

[0024] Through the above technical solution, the parallel handles can provide more stable support. At the same time, it will make your gripping action smoother and more comfortable, reducing the fatigue caused by unnatural gripping posture.

[0025] The beneficial effects of the utility model are as follows:

[0026] 1. This utility model is equipped with an angle adjustment component. By adjusting the angle, the noise-reducing treadmill can simulate different terrains such as uphill, downhill and flat ground. This not only allows you to experience the feeling of outdoor running indoors, but also increases the fun and diversity of running.

[0027] 2. This utility model is equipped with a transmission component that can withstand the high loads generated when running. Whether it is your weight or the impact force when running, the transmission component can work stably and will not easily malfunction or be damaged. This ensures the long-term reliable operation of the treadmill and reduces the frequency of maintenance and replacement of parts. BRIEF DESCRIPTION OF THE DRAWINGS
