Detailed Implementation

[0021] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0022] like Figure 1 As shown, a treadmill pantograph folding structure according to this utility model includes a treadmill body 1 and a pantograph 2. A connecting seat 3, a connector 4, and a fastening component 5 are provided between the treadmill body 1 and the pantograph 2. In the technical solution of this application, the connecting seat 3 can be fixedly connected to the pantograph 2, and the connector 4 can be fixedly connected to the treadmill body 1; alternatively, the connecting seat 3 can be fixedly connected to the treadmill body 1, and the connector 4 can be fixedly connected to the pantograph 2.

[0023] Specifically, the connecting seat 3 includes two opposing stiffening plates, forming an assembly space between them to accommodate the connecting head 4. Each stiffening plate has an assembly hole. The connecting head 4 has an open-type matching hole 41, extending into the assembly space of the connecting seat 3. The fastening assembly 5 includes an assembly shaft 51 and a fastening screw 52. The assembly shaft 51 is adapted to the assembly hole, and the assembly shaft 51 and the fastening screw 52 are threaded together to clamp and fix the connecting seat 3. The connecting head 4 also has an adjusting assembly 6 for adjusting the size of the open-type matching hole 41. In the locked state, the open-type matching hole 41 is fixed relative to the assembly shaft 51.

[0024] This application's technical solution utilizes an adjustable connection structure consisting of a connecting seat 3, a connecting head 4, and a fastening component 5, located between the treadmill body 1 and the gimbal 2. Adjusting the angle between the gimbal 2 and the treadmill body 1 allows the gimbal 2 to fold. Loosening the open-type matching hole 41 and the mounting shaft 51 allows them to rotate relative to each other. Loosening the mounting shaft 51 and the fastening screw 52 allows the mounting shaft 51 to rotate relative to the connecting seat 3. At this point, the user can rotate the gimbal 2 to adjust the angle between the gimbal 2 and the treadmill body 1. Once the target angle is reached, tightening the mounting shaft 51 and the fastening screw 52, ​​and then tightening the open-type matching hole 41 and the mounting shaft 51 using the adjusting component 6, fixes the relative positions of the gimbal 2 and the treadmill body 1, thereby achieving the folding of the gimbal 2.

[0025] In a preferred embodiment, the assembly shaft 51 is an irregularly shaped shaft including a D-shaped shaft segment. One of the assembly holes on the two stiffeners is an irregularly shaped assembly hole 31 with a D-shaped cross-section, and the other is a circular assembly hole 32. The shaft segment that mates with the irregularly shaped shaft in the irregularly shaped assembly hole 31 has a D-shaped cross-section, and the shaft segment that mates with the circular assembly hole 32 has a circular cross-section. It should be noted that the D-shape in this application refers to a rectangular notch cut along the axial direction of the cylinder on its side surface. The D-shape in this application ensures the shaft's rotational capacity and also allows for positioning within the irregularly shaped assembly hole 31.

[0026] Furthermore, an open bushing 7 is provided between the open-type matching hole 41 and the assembly shaft 51. In the locked state, the open bushing 7 is coaxially fitted with the assembly shaft 51, with the inner wall of the open bushing 7 abutting against the outer wall of the assembly shaft 51. The open-type matching hole 41 is coaxially fitted with the open bushing 7, with the inner wall of the open-type matching hole 41 abutting against the outer wall of the open bushing 7. The opening of the open-type matching hole 41 is axially aligned with the axial direction of the open-type matching hole 41, and the opening of the open bushing 7 is axially aligned with the axial direction of the open bushing 7. When the adjusting component 6 adjusts the size of the opening of the open-type matching hole 41, the adjusting component 6 applies a force to the open-type matching hole 41, causing the opening of the open-type matching hole 41 to narrow. At this time, the inner wall of the open-type matching hole 41 applies a force to the open bushing 7, and the narrowing of the opening of the open bushing 7 makes the inner wall of the open bushing 7 fit tightly against the assembly shaft 51, ensuring the stability of the relative position between the assembly shaft 51 and the open-type matching hole 41. It should be emphasized that both the open-type matching hole 41 and the open-type bushing 7 in this application are formed from a material with elastic deformation, such as aluminum alloy. Furthermore, an oil guide groove 71 is provided on the outer wall of the open-type bushing 7, with the length direction of the oil guide groove 71 parallel to the axial direction of the open-type bushing 7. The oil guide groove 71 can store lubricating oil or grease to prevent the open-type matching hole 41, the open-type bushing 7, and the assembly shaft 51 from being corroded and jammed, ensuring convenient adjustment of the connection structure angle.

[0027] Furthermore, gaskets are provided between both stiffening plates and connector 4. A shaped gasket 8 is provided between the stiffening plate containing the irregularly shaped assembly hole 31 and connector 4, and a circular gasket 9 is provided between the stiffening plate containing the circular assembly hole 32 and connector 4. The use of gaskets serves to reduce vibration, prevent loosening, and reduce wear on parts.

[0028] In one feasible embodiment, the adjusting assembly 6 includes an adjusting screw 61 and an adjusting nut 62. Adjusting holes 42 are provided on both sides of the opening of the open-type matching hole 41 on the connector 4. The threaded end of the adjusting screw 61 passes through the two adjusting holes 42 in sequence. The adjusting nut 62 is threadedly connected to the end of the adjusting screw 61 that extends out of the adjusting hole 42. The length direction of the adjusting screw 61 is perpendicular to the axial direction of the open-type matching hole 41.

[0029] In a preferred embodiment, at least one stiffener of the connecting seat 3 has a first limiting protrusion 33 and a second limiting protrusion 34, and an adjusting section 35 connects the first limiting protrusion 33 and the second limiting protrusion 34. A limiting block 43 is provided on the connecting head 4, located between the first limiting protrusion 33 and the second limiting protrusion 34, and the limiting block 43 abuts against and limits the first limiting protrusion 33 and the second limiting protrusion 34 respectively. The adjusting section 35 is arc-shaped, and the limiting block 43 is cylindrical; the arc-shaped outer contour of the adjusting section 35 contacts the cylindrical arc surface of the limiting block 43. The contact between the arc-shaped adjusting section 35 and the cylindrical limiting block 43 guides rotation, facilitating angle adjustment through rotation.

[0030] The included angle between the first limiting protrusion 33, the center point of the circular mounting hole 32, and the second limiting protrusion 34 is 0 to 90 degrees. Preferably, the included angle is 90 degrees, allowing for 90-degree angle adjustment. And / or, the included angle between the first limiting protrusion 33, the center point of the irregularly shaped mounting hole 31, and the second limiting protrusion 34 is 0 to 90 degrees. Preferably, the included angle is 90 degrees, allowing for 90-degree angle adjustment.

[0031] In a preferred embodiment, the gimbal 2 includes a panel and a frame. The panel is detachably mounted on the frame, which includes two spaced-apart connecting parts, each of which is fixedly fitted with a connecting seat 3. The treadmill body 1 includes support rods and a base plate. A support rod is provided on each side of the base plate's width, and a connecting head 4 is fixedly mounted on each of the two support rods. The connecting head 4 connects to the corresponding connecting seat 3, thus connecting the gimbal 2 to the treadmill body 1. More preferably, the gimbal 2 can be adjusted to be parallel to the conveyor belt of the base plate for easy placement of items such as water cups and mobile phones. The gimbal 2 can also be adjusted to be tilted relative to the conveyor belt of the treadmill body 1 for easy placement of items such as e-readers and cameras. Even more preferably, the support rods are configured as rotatable structures, and can be connected to the base plate via a pivot. During transportation, the support rods can be stored on both sides of the base plate's width, while the frame of the gimbal 2 can be stored around the base plate by angle adjustment, improving transportation convenience. During installation, after rotating the support rod to the target position, use fasteners such as pins to fix the support rod to the base plate. Then, adjust the gimbal 2 to the target angle and install the gimbal 2 panel onto the gimbal 2 frame. Installation is convenient.
