Technical Field
[0001] This utility model relates to the field of fabrics, and in particular to a fabric tensioning device. Background Technology
[0002] In the existing technology, fabric is a commonly used material in decoration, including various types of fabrics such as chemical fiber carpets, non-woven wall coverings, linen, nylon, colored adhesive tape, and flannel. Fabric plays a significant role in decoration and display, and is often an indispensable main force in the entire sales space. The extensive use of fabric for wall decoration, partitions, and background treatment can also create a good commercial space display style.
[0003] Existing tensioning structures are often too fixed in design and lack sufficient flexibility. They can usually only adapt to one or a few specific types of fabrics and cannot adapt well to changes in fabric thickness, softness, hardness, elasticity, etc. This limits their effectiveness in handling different fabrics to some extent. Utility Model Content
[0004] This application provides a fabric tensioning device that solves the problem that the design of tensioning structures in the prior art is often too fixed and lacks sufficient flexibility. They can usually only adapt to one or a few specific types of fabrics and cannot adapt well to changes in fabric thickness, softness, hardness, elasticity, etc., which to some extent limits their effectiveness in handling different fabrics.

[0008] As a further improvement to the above technical solution: a first elastic element is provided in the fourth groove; the first elastic element resets the position of the push rod until the third block is inserted into the third groove.
[0009] As a further improvement to the above technical solution: a fifth groove is provided on the side wall of the second groove; a guide rod is provided in the fifth groove; a locking block is provided on the second block; the locking block slides on the guide rod; a second elastic element is sleeved on the guide rod; one end of the second elastic element is fixedly connected to the fifth groove, and the other end of the second elastic element is fixedly connected to the locking block.
[0010] As a further improvement to the above technical solution: a first inclined surface is provided on the third block; a second inclined surface corresponding to the first inclined surface is provided on the third groove; the first inclined surface contacts the second inclined surface; when the third block is inserted into the third groove, the contact between the first inclined surface and the second inclined surface causes the second block to move outward until the second block restricts the position of the first block.
[0011] As a further improvement to the above technical solution: a plurality of slots corresponding to the second block are provided on the side wall of the first groove; a plurality of slots are provided at the positions to be stopped as needed.

[0013] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0014] 1. Due to the synergistic effect of the second and first elastic elements, the inclined surfaces of the second and third blocks achieve seamless switching between flexible pre-tensioning and rigid locking, adapting to the tension requirements of different stretchable fabrics such as linen and flannel; the slots on the side wall of the first groove and the locking blocks of the second block form multi-level positioning points, allowing users to quickly select the appropriate tension height for the current fabric via the handle, compatible with fabric types with thickness differences of up to 200% (such as from gauze to synthetic fiber carpets); when the fabric tension changes, the second elastic element pushes the locking blocks to slide along the guide rod, and the inclined surfaces of the third and second blocks... The top triggers the second expansion block to compensate for tension fluctuations in real time and avoid slack caused by the fabric's extensibility. When the external force exceeds the threshold of the elastic element, the second block disengages from the slot and slides along the first slot to release excessive tension and prevent fabric tearing or damage to the equipment structure. Pressing down the handle drives the push rod to compress the first elastic element. After the third block disengages from the third slot, the tension roller can rise and fall freely. After releasing the handle, the elastic element automatically resets and locks, allowing a single person to complete the entire process adjustment with a gesture. The inclined contact design between the third block and the third slot reduces frictional resistance and ensures a smooth and unhindered adjustment process, making it especially suitable for high-intensity continuous operation scenarios.

[0023] The adjusting device 3 includes a first block 31, a second block 32 that restricts the position of the first block 31, a third block 33 that adjusts the position of the second block 32, and a push rod 34 that drives the third block 33 to move. The first block 31 has second grooves 311 on both sides. The second block 32 slides in the second grooves 311. The push rod 34 is connected to the third block 33. The third block 33 and the second block 32 are arranged in two sets opposite to each other. The second block 32 has a third groove 321. The third block 33 is inserted into the third groove 321. The first block 31 has a fourth groove 312. The push rod 34 slides in the fourth groove 312.
[0024] The fourth groove 312 is provided with a first elastic element 313; the first elastic element 313 resets the position of the push rod 34 until the third block 33 is inserted into the third groove 321.
[0025] A fifth groove 314 is provided on the side wall of the second groove 311; a guide rod 315 is provided in the fifth groove 314; a locking block 322 is provided on the second block 32; the locking block 322 slides on the guide rod 315; a second elastic member 316 is sleeved on the guide rod 315; one end of the second elastic member 316 is fixedly connected to the fifth groove 314, and the other end of the second elastic member 316 is fixedly connected to the locking block 322.
[0026] The third block 33 has a first inclined surface 331; the third groove 321 has a second inclined surface 3211 corresponding to the first inclined surface 331; the first inclined surface 331 contacts the second inclined surface 3211; when the third block 33 is inserted into the third groove 321, the contact between the first inclined surface 331 and the second inclined surface 3211 causes the second block 32 to move outward until the second block 32 restricts the position of the first block 31.
[0027] The side wall of the first groove 11 is provided with several slots 12 corresponding to the second block 32; the slots 12 are provided at the positions required for stopping.
[0028] The first piece 31 is equipped with a handle 5 for easy adjustment of the tension roller.
[0029] Due to the synergistic effect of the second elastic element 316 and the first elastic element 313, the inclined surfaces of the second block 32 and the third block 33 achieve seamless switching between flexible pre-tensioning and rigid locking, adapting to the tension requirements of different stretchable fabrics such as linen and flannel; the slot 12 on the side wall of the first groove 11 and the locking block 322 of the second block 32 form multi-level positioning points, allowing users to quickly select the tension height suitable for the current fabric via the handle 5, compatible with fabric types with thickness differences of up to 200% (such as from gauze to synthetic fiber carpet); when the fabric tension changes, the second elastic element 316 pushes the locking block 322 to slide along the guide rod 315, and the inclined surfaces of the third block 33 and the second block 32... When the second piece 32 is triggered to expand outward, it compensates for tension fluctuations in real time and avoids slack caused by the extensibility of the fabric. When the external force exceeds the threshold of the elastic element, the second piece 32 disengages from the slot 12 and slides along the first slot 11 to release excessive tension and prevent fabric tearing or damage to the equipment structure. Pressing down the handle 5 drives the push rod 34 to compress the first elastic element 313.

After releasing the handle 5, the elastic element is automatically locked after reset, and the entire process adjustment can be completed by a single person's gesture. The inclined contact design between the third piece 33 and the third slot 321 reduces frictional resistance and ensures a smooth and unhindered adjustment process, which is especially suitable for high-intensity continuous operation scenarios.
