Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment as required without making a contribution, but all the embodiments are protected by the patent law within the scope of the claims of the present invention.
The present embodiment relates to a folding treadmill, as shown in fig. 1-3, comprising: a front panel 1, a rear panel 2 and an automatic folding device 4.
The front plate 1 is loaded with a treadmill motor. The back plate 2 is rotatably assembled with the front plate 1. When the running machine is used, the front plate 1 and the rear plate 2 are combined into a complete running plate. When the treadmill is stored, the front board 1 and the rear board 2 are folded. The folding connector is used for realizing the rotating assembly between the front plate 1 and the back plate 2. The automatic folding device 4 is partially provided on the front panel 1 and partially provided on the rear panel 2. The automatic folding device 4 is used for driving the rear plate 2 to rotate relative to the front plate 1, thereby realizing the opening or the folding of the running board.
As shown in fig. 1-3, the hinge assembly 22 includes: a first pulley 23, a second pulley 24, a third pulley 25, a fourth pulley 26, a first stopper 27, and a first group cord.
The first pulley 23 is mounted on the front plate 1 on the side close to the motor wheel 20. The second pulley 24 is mounted on the front plate 1 on the side closer to the rear plate 2. A third pulley 25 is mounted on the front plate 1 between the first pulley 23 and the second pulley 24. A fourth pulley 26 is mounted on the rear plate 2 adjacent to the front plate 1. The first blocking piece 27 is arranged on the side of the rear plate 2 far away from the fourth pulley 26. The first group of ropes is wound among the first pulley 23, the second pulley 24, the third pulley 25, the fourth pulley 26 and the first stopper 27. The first set of pull cords is used to pull the back panel 2 so that the back panel 2 is drawn toward the front panel 1 side when folded and away from the front panel 1 side when unfolded.
Specifically, when the folding board of running was opened, cardboard 31 block was in thimble 30 to guarantee folding steadiness and the reliability of running the board under the open mode. When the folding running board is folded, the thimble 30 drives the clamping board 31 to be separated from the thimble 30 under the pulling of the second group of pulling ropes, so that the front board 1 and the rear board 2 are bent, the front board 1 and the rear board 2 are not on the same plane, and the force application of the component force of the subsequent first group of pulling ropes is facilitated.
Note that, the first blocking piece 27 and the second blocking piece 29 each include: a baffle body 33 and a thread passing rod 34. The flap body 33 is rotatably assembled with the rear plate 2. Preferably, the flap body 33 is comma-shaped. The baffle body 33 is provided with a wire slot, thereby facilitating the pulling of the pull rope. The threading rod 34 is disposed on one side of the blocking piece body 33 away from the rotating end, and the threading rod 34 is used for the first group of pulling ropes or the second group of pulling ropes to be threaded so as to change the pulling direction. The thimble 30 is provided with a fixing boss for fixing the second group of pulling ropes 32 on one side close to the clamping plate 31. The first group of pull ropes and the second group of pull ropes are both steel wire ropes.
The working principle of the present embodiment is roughly as follows: when the folding treadmill is folded, the motor wheel 20 is driven to rotate by the treadmill motor, the motor wheel 20 drives the first blocking piece 27 to rotate for an angle through the first group of pull ropes and the four pulleys, so that the first blocking piece 27 drives the second blocking piece 29 to rotate, the second blocking piece 29 drives the thimble 30 to rotate through the second group of pull ropes, the thimble 30 ejects the blocking board 31 upwards through rotation, and the blocking board 31 is fixed on the front board 1, so that when the blocking board 31 is ejected upwards, the front board 1 is bent relative to the rear board 2, and at the moment, the front board 1 and the rear board 2 are not on the same plane; then, the treadmill motor continues to wind the first group of pull ropes through the rotation of the motor wheel 20, at this time, after the first blocking piece 27 rotates by an angle, the pulling direction of the pull ropes is adjusted, so that the pull ropes provide an on-line component force and a horizontal component force while winding, the rear plate 2 is pushed by the two component forces to rotate and approach to one side of the front plate 1 until the rear plate 2 rotates to be perpendicular to the bottom surface, and then the folding of the treadmill is completed; when the treadmill is opened, the treadmill motor rotates reversely, so that the motor wheel 20 drives the first blocking piece 27 to rotate through the first group of pull ropes 28, the rotation of the first blocking piece 27 drives the second blocking piece 29 to rotate, the ejector pin 30 is reset, the treadmill motor continues to rotate until the rear plate 2 and the front plate 1 are in the same plane, and at the moment, the ejector pin 30 is buckled with the blocking plate 31, so that the treadmill is opened; the folding running machine arranged in this way can realize automatic folding and unfolding of the running board, and has the advantages of simple and convenient folding operation, and firmness when being unfolded.
The above description is only for the purpose of illustration and not limitation, and other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention should be covered by the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
