The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modifications and equivalent variations of the above embodiment according to the technical spirit of the present invention are within the scope of the present invention.
The implementation mode is as follows: when the device designed by the invention is used for running normally without acceleration or deceleration, a runner runs in the middle area, namely, runs in the area between the two sliding blocks 27 and 400mm-500mm, at the moment, the supporting plate 16 is forced to move downwards, the supporting plate 16 moves downwards to drive the sliding strips 19 at the two sides to move downwards through the fixing plate 36 and the sliding rod 34, the sliding strips 19 move to drive the first triggering triangular block 25 and the second triggering triangular block 26 on the sliding strips to move downwards, under the action of the inclined surface at the upper end of the first triggering block 21, the sliding strips 19 transversely move relative to the supporting plate 16, namely transversely move downwards simultaneously, the inclined surfaces on the two second triggering blocks 22 and the inclined surfaces on the two second triggering triangular blocks 26 are always kept parallel to each other, the gap distance is constant, and the speed adjustment of the subsequent running belt 3 is not influenced.
When the runner needs to accelerate or decelerate, the runner runs forwards or backwards on the running belt 3 relative to the running belt 3, if the runner runs forwards, the supporting plate 16 at the front end is stressed to swing forwards under the action of the two connecting rods 32 at the front side, the first supporting block 18 at the front side is stressed to generate elastic deformation and the first supporting block 18 at the rear side is pulled to generate elastic deformation in the swinging process, on one hand, the swinging amplitude of the supporting plate 16 is smaller, on the other hand, the supporting plate 16 is allowed to swing for a certain angle due to the elastic deformation of the supporting plate, and meanwhile, the effect of stabilizing the supporting plate 16 when the supporting plate 16 moves is achieved. When the support plate 16 swings forward, the slider 27 near the front side slides downward with respect to the fixed sleeve 20, and the third supporting block 28 is deformed under pressure; the slider 27 located on the rear side slides upwards with respect to the fixed sleeve 20, the slider 27 being separated from the third support block 28. In addition, the sliding of the trapezoidal sliding block 30 and the trapezoidal sliding groove 29 during the swinging of the support plate 16 can ensure the normal swinging of the support plate 16.
The supporting plate 16 swings to drive the sliding strip 19 to swing, because the second trigger triangular block 26 is close to the edge of the sliding strip 19 relative to the first trigger triangular block 25, in the swinging process, the swinging speed of the second trigger triangular block 26 is greater than that of the first trigger triangular block 25, although the first trigger triangular block 25 is initially contacted with the first trigger block 21, after the supporting plate 16 swings for a small angle, the second trigger triangular block 26 is inevitably contacted with the second trigger block 22, and the extrusion degree of the second trigger triangular block 26 extruding the second trigger block 22 in the subsequent continuous swinging process is greater than the pressurization degree of the first trigger triangular block 25 extruding the first trigger block 21. When the second trigger triangular block 26 extrudes the second trigger triangular block 22, the second trigger triangular block 22 also extrudes the second trigger triangular block 26 in the reverse direction, at this time, under the action of the spring 35, the second trigger triangular block 26 applies an extrusion force to the second trigger triangular block 22, the spring 35 has the function of ensuring that the second trigger triangular block 26 can apply an extrusion force to the second trigger triangular block 22, on the other hand, the spring 35 can also play a role of resetting the sliding strip 19, and the sliding strip 19 can be successfully reset after the support plate 16 is pressed and disappears; the second trigger block 22 presses the pressure sensor 23, and the pressure sensor 23 transmits a signal to the motor 5 to control the motor 5 to operate to change the rotation speed of the running belt 3. After the speed adjustment is finished, the runner actively slows down the steps and automatically returns to the middle area, and the speed at the moment is the adjusted speed and cannot be changed when the runner returns to the middle area; when the speed is reduced, the angle is automatically accelerated after the adjustment is finished, and the user can return to the middle area to continue running.
