[0001] The embodiments of the present application relate to the field of sports equipment, and particularly to a double-lifting mechanism for a treadmill and a treadmill. Background Art

[0002] Treadmills, as aerobic exercise equipment, are becoming increasingly popular among consumers. Treadmills can exercise the user's physical strength, tolerance, and cardiopulmonary function to achieve the purpose of scientific exercise. Most of the treadmills sold on the market currently have a slope adjustment function, and users can set the slope of the running part of the treadmill by themselves to adjust the intensity of the exercise. However, the existing adjustment methods of treadmills are single, resulting in a single slope adjustment gear. Utility Model Content

[0003] The embodiments of the present application provide a double-lifting mechanism for a treadmill and a treadmill, which respectively adjust the slope of the treadmill at both ends of the treadmill, realizing multi-slope adjustment of the treadmill.

[0004] The first aspect of the embodiments of the present application provides a double-lifting mechanism for a treadmill, which is applied under the treadmill body and includes:

[0005] A first lifting mechanism for installing with the first end of the treadmill body, including a support rod and a telescopic driving device. When installed, the first end of the support rod is used for rotatably connecting with the bottom of the treadmill body, and the second end of the support rod is used for abutting against the ground; the first end of the telescopic driving device is rotatably connected with the support rod, and the second end of the telescopic driving device is rotatably connected with the treadmill body. The telescopic driving device drives the support rod to rotate around the hinge point at the first end of the support rod.

[0006] A second lifting mechanism for installing with the second end of the treadmill body, including an adjustment block for rotatably assembling with the second end of the treadmill body. At least two support surfaces are distributed on the outer edge of the adjustment block around the rotation center with different radii.

[0007] The first lifting mechanism and the second lifting mechanism are adjusted independently.

[0008] The first lifting mechanism includes two support rods, and the two support rods are fixedly connected by a connecting frame. The second end of the telescopic driving device is rotatably connected with the connecting frame, and the telescopic driving device drives the connecting frame to drive the support rod to rotate around the hinge point at the first end of the support rod.

[0009] In some embodiments, a roller is installed at the second end of the support rod. When the support rod rotates around the hinge point at the first end, the second end of the support rod rolls on the ground through the roller.

[0010] In some embodiments, a hinge block is provided on the adjusting block, and a first through hole is provided on the hinge block; the second lifting mechanism further includes a connecting member and a rotating shaft. A second through hole is provided at the first end of the connecting member, and the second end of the connecting member is fixedly connected to the treadmill body; the rotating shaft passes through the first through hole and the second through hole to hinge the connecting member to the adjusting block.

[0011] In some embodiments, two sets of the second lifting mechanisms are provided, and when installed, the axes of the two rotating shafts of the two second lifting mechanisms are on the same straight line.

[0012] In some embodiments, the second lifting mechanism further includes a limiting rod for being installed at the bottom of the treadmill body. A limiting groove is provided on the adjusting block. When the adjusting block rotates to one of the supporting surfaces for support, the rod body portion of the limiting rod is located in the limiting groove.

The supporting surfaces include a first supporting surface and a second supporting surface, which are respectively arranged at two vertices of the adjusting block, so that a triangle with unequal three sides is formed among the rotation center of the adjusting block, the midpoint of the first supporting surface, and the midpoint of the second supporting surface.

[0014] The whole shape of the adjusting block is a right triangle. The first supporting surface is located at the right angle. When the first supporting surface contacts the ground for support, the hypotenuse of the adjusting block opposite to the first supporting surface abuts against the lower surface of the treadmill body; when the second supporting surface contacts the ground for support, the right-angle side of the adjusting block opposite to the second supporting surface abuts against the lower surface of the treadmill body.

[0015] In some embodiments, a plurality of anti-slip strips are provided on the supporting surface.

[0016] Another aspect of the embodiments of the present application provides a treadmill, including a treadmill body, and a double-lifting mechanism of the treadmill as described in any one of the above solutions is provided at the bottom of the treadmill body.

[0032] As Figures 1 to 4As shown, according to an embodiment of the present application, a treadmill double-lifting mechanism is provided. It is arranged below the treadmill body 1 and includes a first lifting mechanism 2 arranged on the front side of the treadmill body 1 and a second lifting mechanism 3 arranged on the rear side of the treadmill body 1. Both the first lifting mechanism 2 and the second lifting mechanism 3 can independently adjust the slope of the treadmill running platform.

[0033] The first lifting mechanism 2 includes two support rods 21 with the same shape and size. The first ends of the two support rods 21 are both hinged to the bottom of the treadmill body 1, and the second ends of the two support rods 21 are both used to abut against the ground. A connecting frame 22 is arranged between the two support rods 21. The connecting frame 22 is fixedly connected to the support rods 21 on both sides, so that the connecting frame 22 drives the two support rods 21 to move synchronously. The first lifting mechanism 2 further includes a telescopic driving device 23. The first end of the telescopic driving device 23 is fixedly installed on the treadmill body 1, and the second end of the telescopic driving device 23 is rotatably connected to the connecting frame 22. The second end of the telescopic driving device 23 drives the connecting frame 22 to drive the support rod 21 to rotate around the hinge point at the first end of the support rod 21.

[0034] In some embodiments, the telescopic driving device 23 includes a motor and a lead screw mechanism connected to the output end of the motor. The motor drives the lead screw to expand and contract to adjust the angle between the support rod 21 and the ground, thereby adjusting the height of the front end of the treadmill running platform from the ground and realizing the adjustment of the slope of the treadmill running platform.

[0035] In some embodiments, a roller 24 is installed at the second end of the support rod 21. When the support rod 21 rotates around the hinge point at the first end, the second end of the support rod 21 rolls on the ground through the roller 24, which is convenient for slope adjustment.

[0036] The second lifting mechanism 3 includes two adjusting blocks 31. The adjusting blocks 31 are respectively hinged to the treadmill body 1. When the two adjusting blocks 31 are installed at the bottom of the treadmill body 1, the rotation axes of the two adjusting blocks 31 are on the same straight line, so that the supporting heights of the two adjusting blocks 31 for the rear end of the treadmill body 1 are the same. And first support surfaces 315 and second support surfaces 316 are respectively arranged at the edges of the adjusting blocks 31. The first support surfaces 315 and the second support surfaces 316 are distributed around the hinge point with different radii. When different support surfaces contact the ground, the height of the rear end of the treadmill running platform from the ground is different, thereby realizing the adjustment of the slope of the treadmill running platform.

[0037] In some embodiments, a plurality of anti-slip strips are arranged on the support surface of the adjusting block 31 to increase the friction between the support surface of the adjusting block 31 and the ground.

[0038] In some embodiments, the adjusting block 31 is triangular as a whole, and the first supporting surface 315 and the second supporting surface 316 are respectively located at two vertices of the adjusting block 31, such that a triangle with unequal sides is formed among the axis of the first through hole 313, the midpoint of the first supporting surface 315, and the midpoint of the second supporting surface 316.

[0039] In some embodiments, the adjusting block 31 is a right triangle as a whole, and the first supporting surface 315 is located at the right angle. When the first supporting surface 315 contacts the ground for support, the hypotenuse of the adjusting block 31 opposite to the first supporting surface 315 abuts against the lower surface of the treadmill body 1; when the second supporting surface 316 contacts the ground for support, the right-angle side of the adjusting block 31 opposite to the second supporting surface 316 abuts against the lower surface of the treadmill body 1, improving the stability of the support of the adjusting block 31.

[0040] In some embodiments, a first groove 311 is provided on the first side of the adjusting block 31, an articulated block 312 is provided in the first groove 311, and a first through hole 313 is provided on the articulated block 312. The second lifting mechanism 3 further includes a connecting member 32 and a rotating shaft 33. The connecting member 32 is a U-shaped plate with a third groove 321 in the middle, and a second through hole 322 is provided at the first end of the connecting member 32. During installation, the articulated block 312 is placed in the third groove 321 of the connecting member 32, and the first through hole 313 is opposite to the second through hole 322. The rotating shaft 33 passes through the first through hole 313 and the second through hole 322 to realize the articulation between the adjusting block 31 and the connecting member 32. The second end of the connecting member 32 is fixedly connected to the treadmill body 1, realizing the articulation between the adjusting block 31 and the treadmill body 1. The size of the connecting member 32 is set such that when the second supporting surface 316 contacts the ground, the bottom plate of the second end of the connecting member 32 is located inside the first groove 311, facilitating the stable abutment of the right-angle side of the adjusting block 31 opposite to the second supporting surface 316 against the lower surface of the treadmill body 1.

[0041] In some embodiments, the bottom plate of the second end of the connecting member 32 is connected to the treadmill body 1 by welding, screw connection, or bonding.

[0042] In some embodiments, the second lifting mechanism 3 further includes a limiting rod 34, and the limiting rod 34 is fixedly connected to the bottom of the treadmill body 1. Second grooves 314 are respectively provided on the two adjusting blocks 31, and the second grooves 314 of the two adjusting blocks 31 are opposite to each other, such that when the adjusting block 31 rotates to the position where the second supporting surface 316 contacts the ground for support, both ends of the limiting rod 34 are respectively located in the two second grooves 314, restricting the further rotation of the adjusting block 31 in the direction of the limiting rod 34. When the adjusting block 31 rotates to the position where the first supporting surface 315 contacts the ground for support, the surface of the adjusting block 31 opposite to the first supporting surface 315 abuts against the bottom surface of the treadmill body 1.

[0043] As shown Figures 5 - 8 in the figure, there are several slope states of the treadmill. Figure 5 This is the first state of the treadmill slope adjustment. The second support surface 316 of the adjustment block 31 is in contact with the ground and the first lifting mechanism 2 is in the initial state. At this time, the running platform plane is in a horizontal state. Figure 6 This is the second state of the treadmill slope adjustment. On the basis of the first state, the adjustment block 31 is rotated counterclockwise so that the first support surface 315 abuts against the ground, and the first lifting mechanism 2 is in the initial state. Since the distance between the first support surface 315 and the rotating shaft 33 is less than the distance between the second support surface 316 and the rotating shaft 33, when the adjustment block 31 rotates to this position, the support height at the rear end of the treadmill body 1 decreases. Figure 7 On the basis of the first state, the adjustment block 31 keeps the second support surface 316 in contact with the ground, and the support rod 21 increases the angle between the support rod 21 and the ground under the drive of the telescopic drive device 23, so that the support height at the front end of the treadmill body 1 increases. Figure 8 On the basis of the second state, the adjustment block 31 keeps the first support surface 315 in contact with the ground, and the support rod 21 increases the angle between the support rod 21 and the ground under the drive of the telescopic drive device 23, so that the support height at the front end of the treadmill body 1 increases, thereby further increasing the slope between the running platform and the ground on the basis of the second state.

[0044] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0045] 1. Lifting mechanisms are respectively arranged at both ends of the bottom of the treadmill body, and both the first lifting mechanism and the second lifting mechanism can independently adjust the slope of the treadmill running platform.

[0046] 2. The adjustment block of the second lifting mechanism is provided with at least two support surfaces, and the distance between each support surface and the rotating shaft is different, so as to realize the adjustment of different support heights.

[0047] 3. A limiting rod is installed at the bottom of the second lifting mechanism body, and a second groove is provided on the adjustment block. When the second support surface is in contact with the ground, the rod body part of the limiting rod is located in the second groove, which is used to limit the further rotation of the adjustment block to the side of the limiting rod.

[0048] 4. Anti-slip strips are provided on each support surface of the adjustment block to improve the support stability of the adjustment block at the current support position.

[0049] Compared with the prior art, the treadmill with a double lifting mechanism of the present utility model has multiple slope adjustment gears to meet the different training needs of users.

[0050] The above are only some embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
