DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 and Figure 2 and Figure 3 As shown, the adaptive tensioning mechanism for the zipper tape includes a block-shaped body 1, the lower part of the body 1 has a connecting portion for connecting to a corresponding frame, the body 1 has a recessed tensioning cavity 1c, and also includes a tensioning wheel 6 and an adjustment component. The tensioning wheel 6 is located in the tensioning cavity 1c, the adjustment component is connected to the body 1, the inner end of the adjustment component is connected to the tensioning wheel 6, and the outer end of the adjustment component extends out of the body 1.

[0027] The adjustment component has two functions:

[0028] First, the tensioning wheel 6 is stably connected to the tensioning chamber 1c of the body 1 through the adjustment component;

[0029] Secondly, the position of the tensioning wheel 6 relative to the main body 1 is changed by adjusting the assembly to adapt to the corresponding working occasion.

[0030] The tensioning cavity 1c is recessed from one end of the main body 1 into the middle of the main body 1.

[0031] Such a structure enables the tensioning wheel 6 to be conveniently installed into the main body 1 through the end of the tensioning chamber 1c.

[0032] The adjusting assembly includes an adjusting rod 2, a connecting block 3 and a nut 4. The main body 1 has a penetrating connecting hole 1d. The nut 4 is embedded in the connecting hole 1d and the side of the nut 4 is in surface contact with the side of the connecting hole 1d. The adjusting rod 2 is passed through the main body 1. The nut 4 is sleeved on the adjusting rod 2 and the two are threadedly connected. The inner end of the adjusting rod 2 is axially fixed to the connecting block 3 and the adjusting rod 2 can rotate relative to the connecting block 3. The outer end of the adjusting rod 2 extends out of the main body 1, and the tensioning wheel 6 is connected to the outer end of the connecting block 3.

[0033] Since the nut 4 is located at the connecting hole 1 d , the nut 4 and the adjusting rod 2 maintain a threaded connection.

[0034] Therefore, when the adjusting rod 2 is rotated, the fixed nut 4 causes the adjusting rod 2 to move forward and backward relative to the body 1. Since the connecting block 3 is connected to the adjusting rod 2, it eventually drives the connecting block 3 to move, thereby achieving the purpose of changing the position of the tensioning wheel 6.

[0035] The outer end of the connecting block 3 has a concave connecting notch 3 a, and the tensioning wheel 6 is movably connected to the connecting notch 3 a of the connecting block 3 via a pin 5 .

[0036] Such a structure can stably connect the tensioning wheel 6 to the connecting recess 3 a of the connecting block 3 .

[0037] The tensioning cavity of the main body 1 has long guide holes 1c1 on both sides, and the ends of the pin 5 are embedded in the guide holes 1c1.

[0038] After the pin 5 is inserted into the corresponding guide hole 1c1, the connecting block 3 can move smoothly along the main body 1.

[0039] The connecting portion includes a connecting piece 1a and a connecting piece 1b protruding from the lower part of the main body 1. The connecting piece 1a and the connecting piece 1b are arranged in parallel with an installation gap therebetween.

[0040] The device frame is provided with a protruding connecting boss, which can be embedded in the connecting piece 1a and the connecting piece 2 1b to stably connect the entire mechanism to the device frame.

[0041] The connecting piece 1a, the connecting piece 2 1b and the main body 1 are an integrated structure.

[0042] This can appropriately improve the compactness of the structure.

[0043] The tensioning wheel 6 is cylindrical and has an annular concave embedding groove 6a in the middle of the tensioning wheel 6.

[0044] After the zipper tape is embedded in the embedding groove 6a of the tensioning wheel 6, the zipper tape can be stably tensioned.

[0045] The outer end of the adjusting rod 2 is provided with a hand wheel 7 for the operator to rotate.

[0046] The hand wheel 7 is cylindrical and made of rubber material. The hand wheel 7 is sleeved on the outer end of the adjusting rod 2 and the two are tightly fitted and connected.

[0047] The flexible hand wheel 7 can ensure that the adjusting rod 2 rotates smoothly and the comfort during the rotation is relatively high.

[0048] The adaptive tensioning mechanism for the zipper tape has a tensioning wheel located in the main body, and the main body is firmly fixed to the frame of the operating equipment by fasteners. Therefore, the tensioning wheel is protected by the main body. Even if it is touched, it only touches the main body and the tensioning wheel will not be affected, thereby effectively ensuring its tensioning stability.

[0049] Moreover, since the main body is fixed, compared with the rotating tension wheel, it will not cause greater harm to the operator after being touched. It is also safer, the overall structure is more compact, and has high practical value.

[0050] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
