Description

Improved Structure of Lifting and Folding Treadmill

technical field

The utility model relates to an improved structure for the lifting and folding of a treadmill, in particular to a treadmill that can not only adjust the inclination angle of the treadmill electrically, but also can fold the treadmill electrically when not in use, and can also be used in the state of no electricity. An improved structure for lifting and folding treadmills for manually folding running boards.

Background technique

As shown in Figure 13, it is the first kind of treadmill structure commonly used, and it is provided with a running board frame 51 pivotally on a base 50, and the rear end of the running board frame 51 is respectively pivotally provided with opposite caster brackets 52, and the caster brackets 52 A linkage mechanism 53 is interlocked with the base 50 , the linkage mechanism 53 is pivotally mounted on the base 50 by a motor 531 , and the motor 531 is interlocked with a screw rod 532 .

In this structure, the motor 531 drives the screw 532 to move the caster bracket 52 at the rear end of the running board frame 51 to change the inclination angle of the running board frame 51; When placing the space, because the structure does not have the function of electric retraction, the user still needs to turn up the running board frame 51 with both hands, as shown in Figure 14, and because the weight of the running board frame 51 is very It is very heavy, and it is extremely unsuitable for the elderly with insufficient arm strength or patients who are recovering.

As shown in Figure 15, it is the second type of treadmill structure commonly used. It is provided with a driving motor (not shown) on the base 60 to drive the running belt to rotate, and a group of motors 62 are provided under the running board frame 61. The folding device that drives screw rod 621 to rotate, and in addition drives running board frame 61 with a group of inclination angle device and does inclination adjustment, and inclination angle device is installed on the base 60 with another motor (not shown in the figure), and this motor A telescoping rod 63 is linked, so that the telescoping rod 63 is linked with the caster bracket 64 below the running board frame 61, so that the running board frame 61 is adjusted for inclination.

Although this structure can be used for the electric inclination adjustment of the running board frame, and the electric running board frame is folded, as shown in Figure 16, and it has two driving rear end caster brackets 64 respectively to change the running board frame 61 inclination angle and electric folding. The motor has two motors. If the motor for driving the running belt is added, there will be three motors in total, which not only increases the cost of the overall installation, but also adds components such as a reduction gear box and a screw to make the overall treadmill more stable. The structure of the treadmill becomes more complicated, moreover, the structure does not have the function of manually folding the running board, and if the running board is in a power-off state, the running board cannot be folded, which makes the treadmill take up a lot of space.

As shown in Figure 17, it is a common third type of treadmill structure, which is provided with a motor 72 at the pivot joint of the running board 70 and the armrest frame 71, and the motor 72 drives a screw rod 73 to rotate, and one end of the screw rod 73 is pivotally connected to the A pivot point 74 is used, and the motor 72 is used to drive the screw rod 73 to rotate, so that the screw rod pushes against the pivot point 74, so that the running board 70 can be pivoted and closed.

Although this structure uses a single motor 72 to drive the running board 70 for electric folding, as shown in Figure 18, and it can also be used for manual running board 70 folding when there is no electricity, but the moment arm of the motor 72 driving the screw rod 73 is short, and the running The arm of force from the plate 70 to the pivot point 74 is long, so the load between the motor 72 and the screw rod 73 becomes larger, and the motor 72 is easily damaged, and the motor 72 needs to use a motor with a higher power, so that the overall cost Increase, moreover, the space under the running board 70 is very small, if the motor used is larger, then its accommodating space must be insufficient, add this structure and can not change the electric inclination angle of the running board, if you want to install another motor Adding the function of electric tilt angle to this structure will increase the cost relatively. Therefore, it is necessary to further improve it in view of the various shortcomings of the above-mentioned known structure.
