Detailed Description of the Embodiment

[0036] To facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant drawings. The typical embodiments of the utility model are shown in the drawings.

[0037] Embodiment 1:

[0038] As Figures 1-4As shown in the figure, a treadmill with an armrest that can be adjusted in multiple directions according to the present utility model includes a treadmill 1. The front side of the treadmill 1 is fixedly connected with an adjustment mechanism 2 through a bolt 11. The adjustment mechanism 2 includes a fixed seat 201. A threaded rod 202 is fixedly connected inside the fixed seat 201. One end of the threaded rod 202 is threadedly connected with a pressing block 203. One end of the pressing block 203 is arc-shaped. A friction groove 214 is provided on the pressing block 203. A trapezoidal groove 204 is provided on one side of the fixed seat 201, and there are multiple trapezoidal grooves 204.

[0039] A rotating ring 205 is sleeved on the threaded rod 202. One side of the rotating ring 205 is fixedly connected with a trapezoidal block 206. The trapezoidal block 206 is adapted to the trapezoidal groove 204, realizing the multi-directional adjustment function of the armrest 3. This enables the user to freely and flexibly adjust the position of the armrest 3 according to their personal height, body shape, and exercise habits, thereby finding the most suitable exercise posture for themselves, improving the applicability and comfort of the treadmill 1, further enhancing the user's exercise experience and effect. At the same time, the trapezoidal block 206 can smoothly move along the inclined surface of the trapezoidal groove 204, thereby reducing the force required to rotate the armrest 3, enabling the user to adjust more easily. Moreover, when the armrest 3 rotates to the appropriate position, the trapezoidal block 206 can firmly engage into the interior of the trapezoidal groove 204, ensuring that the armrest 3 is stably fixed and will not shake or loosen during use, improving the stability of the armrest 3.

[0040] As Figure 2 and Figure 4 , an installation shell 209 is fixedly connected to the outside of the rotating ring 205. The installation shell 209 is fixedly connected with the armrest 3 through a cross bar 210 inserted. The installation shell 209 fixedly connected to the outside of the rotating ring 205 provides a stable connection point for the armrest 3, ensuring the stability of the armrest 3 during adjustment and use. At the same time, the installation shell 209 is fixedly connected with the armrest 3 through the cross bar 210 inserted, which not only simplifies the installation and disassembly process of the armrest 3 but also enables the rotation of the rotating ring 205 when the armrest 3 is rotated, realizing convenient adjustment of the armrest 3.

[0041] As Figure 2 and Figure 4, there are two crossbars 210. One end of the two crossbars 210 is fixedly connected with a retaining ring 213 by screws 212. By setting two crossbars 210 and fixedly connecting the retaining ring 213 with screws 212, the connection stability between the handrail 3 and the mounting shell 209 is enhanced, enabling the handrail 3 to be more stable when bearing the user's force, not easily shaking or falling off. At the same time, the two crossbars 210 also provide better balance, allowing the handrail 3 to remain stable during adjustment and use, improving the user's comfort and safety. The retaining ring 213 also plays a certain limiting role, preventing the handrail 3 from sliding out of the crossbar 210 and ensuring the stable connection of the handrail 3.

[0042] As Figure 2 and Figure 4 , one side of the pressing block 203 is magnetically attracted to a retaining piece 211 by a sheet magnet 215. By using the annular sheet magnet 215 to magnetically attract the retaining piece 211, a convenient fixing method is provided for the retaining piece 211. Without the need for tools, users can easily disassemble and assemble the retaining piece 211. At the same time, the retaining piece 211 improves the overall aesthetics, preventing the sealing screw 208 from being exposed and enhancing the beauty of the device.

[0043] As Figure 2 and Figure 4 , there are two trapezoidal blocks 206. The two trapezoidal blocks 206 are arranged in a mirror image structure. By setting two trapezoidal blocks 206 in a mirror image structure, the handrail 3 can be more reliably locked when locked. The two trapezoidal blocks 206 are simultaneously clamped with the trapezoidal groove 204, jointly bearing the pressure of the handrail 3 and improving the installation stability of the device. At the same time, the trapezoidal blocks 206 in the mirror image structure also ensure that the handrail 3 can maintain balance during adjustment without skewing or jamming.

[0044] As Figure 2 and Figure 4 , a motor 4 is provided on the front side of the treadmill 1. The output end of the motor 4 is fixedly connected with a first pulley 5. The motor 4 fixedly connected inside the front side of the treadmill 1 provides a power source for the device, enabling the treadmill 1 to operate reliably, improving the convenience and usage efficiency of the device. At the same time, the first pulley 5 fixedly connected to the output end of the motor 4 transmits the power of the motor 4 to the first rotating shaft 6 of the treadmill 1 through a belt drive, thereby driving the running belt 10 to rotate.

[0045] As Figure 2 and Figure 4, on one side of the top of the treadmill 1, a first rotating shaft 6 is rotatably connected. One end of the first rotating shaft 6 is fixedly connected with a second pulley 7. A belt 8 is sleeved between the second pulley 7 and the first pulley 5. The first rotating shaft 6 rotatably connected to one side of the top of the treadmill 1 provides support and stability for the rotation of the running belt 10, ensuring the safety and comfort of the user when running. At the same time, the belt 8 sleeved between the second pulley 7 fixedly connected to one end of the first rotating shaft 6 and the first pulley 5 at the output end of the motor 4 realizes the effective transmission of the power of the motor 4 to the running belt 10.

[0046] As Figure 2 and Figure 4 , on the other side of the top of the treadmill 1, a second rotating shaft 9 is rotatably connected. A running belt 10 is sleeved between the second rotating shaft 9 and the first rotating shaft 6. The second rotating shaft 9 rotatably connected to the other side of the top of the treadmill 1 cooperates with the first rotating shaft 6 to jointly support and stabilize the running belt 10, ensuring the smoothness and safety of the running belt 10 during operation. At the same time, the running belt 10 sleeved between the second rotating shaft 9 and the first rotating shaft 6 provides a stable running platform for the user, enabling the user to perform comfortable and effective exercises on the treadmill 1.

[0047] The implementation principle of the present utility model is as follows: First, when it is necessary to adjust the position of the armrest 3, hold the friction groove 214 on the pressing block 203 and rotate the pressing block 203 so that the pressing block 203 no longer presses tightly on the rotating ring 205. Then rotate the pressing block 203 on the other side so that the armrest 3 can rotate. Then rotate the armrest 3, and the armrest 3 drives the mounting shell 209 and the rotating ring 205 to rotate through the cross bar 210. At this time, the trapezoidal block 206 moves outward along the inclined surface of the trapezoidal groove 204, making it easier to rotate the armrest 3 and reducing the force required to rotate the armrest 3. When the armrest 3 rotates to the appropriate position, the trapezoidal block 206 is inserted into the trapezoidal groove 204 again. Then rotate the pressing block 203, and the pressing block 203 presses the rotating ring 205 and the fixed seat 201 tightly again, so that the armrest 3 is firmly fixed and cannot rotate anymore;

[0048] Then start the motor 4. The motor 4 drives the first rotating shaft 6 to rotate through the first pulley 5, the belt 8 and the second pulley 7, and then drives the running belt 10 to rotate, enabling the user to exercise.

[0049] Embodiment Two:

[0050] As Figure 3 and Figure 4, a through hole 207 for adding lubricating oil is provided inside the briquette 203. A sealing screw 208 is threadedly connected inside the through hole 207. By providing the through hole 207 for adding lubricating oil inside the briquette 203, it facilitates the user to lubricate and maintain the threaded rod 202, thereby reducing the friction that may occur after long-term use, extending the service life of the device. At the same time, the sealing screw 208 threadedly connected inside the through hole 207 ensures that the lubricating oil will not leak outwards, keeps the environment clean, and avoids the possible adverse effects of the lubricating oil on other components of the treadmill 1.

[0051] The implementation principle of the present utility model is as follows: First, when the briquette 203 is not rotated for a long time, the retaining piece 211 is depressed and the sealing screw 208 is unscrewed. Lubricating oil is poured into the interior through the through hole 207, so as to reduce the internal friction and make it easier to rotate the briquette 203.

[0052] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0053] 1. By using the adjusting mechanism, the structural strength at the rotating position is improved, so that sufficient strength can still be maintained after long-term use;

[0054] 2. The sealing screw can provide a sealing effect and can be conveniently filled with lubricating oil when needed.

[0055] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
