The joint structure of the treadmill running belt

The present invention is an adapter joint structure of a treadmill running belt of a treadmill, in particular, the running belt is a sandwich-fitted rectangular running belt, and the two end edges of the running belt are cut into a zigzag row, wherein the running The two end joints of the bottom layer of the belt are engaged, and at least one film is placed on the engaging joint of the bottom layer, and the serrated rows at the two ends of the surface of the running belt are respectively cross-woven, which are the ends of the surface layer. After the serrated column tip is placed under the film and covered, the fitting of all the fittings in a hot melt manner can be quite firm.

The treadmill mainly has a running board for the user to stand on the bottom frame, and a swingable running belt is arranged above the running board. Since the running belt of the treadmill is tightly matched with the two driving rollers, When it is operated by long-term friction, it is easy to cause cracking and affect its service life. The combination of the running belt of the treadmill adopts a suitable length running belt to superimpose the two ends thereof and then combine them by hot pressing to become a rotary running belt, and the joint area of the joint is small and long-term. Under the action of friction, it is easy to cause breakage and peeling in the joint, which affects its service life. In view of this, the present inventors have carefully studied and developed a more practical joint structure to make the swinging running belt more stable. After many efforts and conceiving and testing, the present invention finally developed the present invention.

In view of the fact that the contact area of the running belt joint is small and the long-term friction is under the action, the crack is easily caused and the service life is affected, thereby developing an adapter joint structure of the treadmill running belt, especially The running belt is a sandwich-fitted rectangular running belt, and the two end edges of the running belt are cut into a zigzag row, wherein the two end joints of the bottom layer of the running belt are engaged, and the bottom layer is engaged with each other. At least one film is placed on the head, and the zigzag rows at the two ends of the running belt are respectively cross-weaved, and the sawtooth tips at the two ends of the surface layer are inserted under the film and covered, and then hot-melt All fittings are fused flat and can be quite strong.

In order to understand the structure of the present invention in more detail, referring to the first figure, the present invention provides an adapter joint structure of a treadmill running belt 1 of a treadmill, wherein the running belt 1 is arranged in a loop on a treadmill. On the roller 9 (as shown in the first figure), the roller 9 is mechanically driven by a power motor (not shown in the prior art), and the running belt 1 can be rotated when the motor is running. When stepping on the top of the running belt 1, a passive state of motion is formed.

Referring to Figures 2 to 6, the running belt 1 of the present invention is a sandwich-fit rectangular running belt 1 which is composed of two PET woven fabrics and a PVC contact layer between two PET woven fabrics. A rectangular running belt 1 composed of 130 phases, the two end fittings of the running belt 1 are cross-cut and separated into a zigzag shape, so that the surface layer 110 of the running belt 1 and the left end 11 and the right end 12 of the bottom layer 120 respectively form a top left layer. 2. The upper right layer 3 and the lower left layer 4 and the lower right layer 5, the zigzag rows 41, 51 of the two end joints of the lower left layer 4 and the lower right layer 5 are engaged and bonded to each other, and are meshed in this embodiment. Three films 6, 7, 8 are placed on the lower left layer 4 and the lower right layer 5 joints, and the film 6, 7, 8 is composed of two pieces of PVC material and a PET mesh cloth positioned therebetween, the running belt 1 The zigzag line 21 of the upper left layer 2 of the left end 11 covers the film 6, 7 and the tip of the zigzag line 21 of the upper left layer 2 is inserted under the film 8 on the lower right layer 5 of the right end 12 and covered, and running The zigzag row 31 of the upper right layer 3 with the right end 12 of the strip covers the film 7, 8 and places the tip of the sawtooth column 31 of the upper right layer 3 at the tip. The film 6 on the lower left layer 4 of the end 11 is covered and covered, that is, the zigzag rows 21 and 31 at the two ends of the surface layer 110 of the running belt are respectively combined in a cross-knit manner, and finally all the fittings are fused and flattened by heat fusion to make the joint. When formed in one piece, a relatively firm running belt 1 can be formed.

In view of the foregoing, the joint of the swinging running belt 1 of the present invention divides the surface layer 110 and the bottom layer 120 into the upper left layer 2, the lower left layer 4, the upper right layer 3, and the lower right layer 5 by a new technique, and the end joints are serrated. The shape, the serrated rows 21, 31 at the two ends of the surface layer 110 of the running belt 1 are respectively combined in a cross-knit manner, and finally all the fittings are fused and flattened by heat fusion to form an integral at the joint, and the sandwich-shaped structure can be formed. A fairly stable running belt with 1 connector.
