Description

Technical Field

[0001] This utility model relates to the field of sofa cable ties, and in particular to a high-strength cable tie for sofas. Background Technology

[0002] Sofa straps are an important part of the internal structure of a sofa, and their quality and design directly affect the sofa's comfort, durability, and support.

[0003] Sofa straps (bandages) come in various types, including hemp straps, steel straps (iron strips), rubber straps, cotton straps, and plastic straps. Different materials offer different properties and are suitable for different applications. For example, hemp straps are strong and elastic, and are often used for sofa bases; while cotton straps are less strong and are generally used for armrests or backrests.

[0004] However, existing sofa cable ties are not only inconvenient to disassemble and replace during use, but also have a small stress-bearing area at the connection between the cable tie and the sofa frame, making them prone to tearing over time, thus affecting their performance.

[0005] Therefore, it is essential to invent a high-strength cable tie for sofas. Utility Model Content

[0006] To solve the above-mentioned technical problems, the present invention provides a high-strength cable tie for sofas, the technical solution of which is as follows: a high-strength cable tie for sofas includes a cable tie body, an I-beam plate and an L-shaped bracket, wherein: an I-beam plate is fixedly installed inside each of the two ends of the cable tie body, an insertion hole is provided through each of the four corners of the I-beam plate, and an eyelet corresponding to the insertion hole is provided through each of the two ends of the cable tie body.

[0007] Each of the four corners of one side of the L-shaped card holder is fixedly installed with a pin corresponding to the insertion hole, and a card plate is fixedly installed on one side of the other end of each pin, forming an L-shape between the pin and the card plate.

[0008] The size of the pin is smaller than the size of the socket;

[0009] The pin with a retaining plate extends into the socket from one end and extends out from the other end of the socket, and the retaining plate engages with the I-beam plate.

[0010] The cable tie body includes a honeycomb mesh strip, an inner layer, an outer layer, and reinforcing ribs. The outer surface of the honeycomb mesh strip is wrapped with the inner layer, the outer surface of the inner layer is wrapped with the outer layer, and a number of reinforcing ribs are evenly arranged on the outer surface of the outer layer.

[0011] The reinforcing rib has a cross-shaped reinforcing strip embedded inside.

[0012] Each of the two plates of the L-shaped card holder has at least one through-hole.

[0013] The outer layer and the outer surface of the reinforcing ribs are coated with a nano-reinforced coating.

[0014] The inner layer is a highly elastic polyurethane elastomer.

[0015] The outer layer is made of high-strength nylon warp and weft yarns.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The overall design of this utility model allows for a fixed connection between the cable tie body and the sofa frame via an L-shaped bracket. The L-shaped bracket can be disassembled and assembled separately from the cable tie body, facilitating the replacement of the cable tie body later. In addition, the I-beam plate design increases the stress area between the L-shaped bracket and the cable tie body, preventing the cable tie body from tearing. This makes the overall design more convenient, flexible, safe, and reliable during use. Attached Figure Description

[0031] Example

[0032] Reference Figure 1-8 A high-strength cable tie for sofas includes a cable tie body 1, an I-beam plate 3, and an L-shaped bracket 5. The I-beam plate 3 is fixedly installed inside each of the two ends of the cable tie body 1 to increase the strength of the two ends of the cable tie body 1 and prevent tearing. Each of the four corners of the I-beam plate 3 has a through hole 4. Each of the two ends of the cable tie body 1 has a hole 2 corresponding to the through hole 4. The through hole 4 and the hole 2 are connected to each other.

[0033] The I-beam plate 3, L-shaped card holder 5, pin 7, and card plate 8 are made of metal.

[0034] Specifically, each of the four corners of one side of the L-shaped card holder 5 is fixedly installed with a pin 7 corresponding to the insertion hole 4, and a card plate 8 is fixedly installed on one side of the other end of the pin 7, forming an L-shape between the pin 7 and the card plate 8.

[0035] Specifically, the size of the pin 7 is smaller than the size of the socket 4;

[0036] Specifically, the end of the pin 7 with the retaining plate 8 extends into the socket 4 from one end of the socket 4 and extends out from the other end of the socket 4. The retaining plate 8 engages with the I-plate 3 to prevent the pin 7 from coming out of the socket 4, thereby ensuring the stability of the cable tie body 1 after installation.

[0037] Specifically, the cable tie body 1 includes a honeycomb mesh strip 11, an inner layer 12, an outer layer 13 and reinforcing ribs 14. The outer surface of the honeycomb mesh strip 11 is wrapped with the inner layer 12, the outer surface of the inner layer 12 is wrapped with the outer layer 13, and a number of reinforcing ribs 14 are evenly arranged on the outer surface of the outer layer 13.

[0038] Reinforcing rib 14 is made of rubber wire;

[0039] The honeycomb mesh strip 11 is made of carbon fiber reinforced polyamide with a wall thickness of 0.5 mm and a unit size of 5 mm × 5 mm. The honeycomb structure can disperse stress, increasing flexural strength by 40%.

[0040] The density of the honeycomb mesh tape 11 gradually increases from the middle to both ends of the cable tie, with a density of 0.3 g / cm³ in the middle and 0.5 g / cm³ at both ends, which enhances the tear resistance of the ends.

[0041] Specifically, the reinforcing rib 14 has a cross-shaped reinforcing strip 15 (material: glass fiber reinforced polyester) embedded inside, which reduces weight while improving tensile stability.

[0042] Specifically, each of the two plates of the L-shaped bracket 5 has at least one through-hole 6 so as to use corresponding fasteners to fix the L-shaped bracket 5 to the sofa frame.

[0043] Specifically, the outer surface of the outer layer 13 and the outer surface of the reinforcing rib 14 are coated with a nano-reinforced coating. The nano-reinforced coating is a nano-silica / polyurethane composite coating with a thickness of 20μm, which improves wear resistance (wear resistance ≥50,000 times) and UV resistance (strength retention rate ≥90% after UV aging test).

[0044] Specifically, the inner layer 12 is a highly elastic polyurethane elastomer, which is formed into an integral structure through hot melt composite technology. The nylon layer provides tensile strength (≥1000N), and the polyurethane layer provides elastic recovery (elastic modulus ≥20MPa), balancing rigidity and flexibility.

[0045] Specifically, the outer layer 13 is made of high-strength nylon 66 warp and weft yarn (21 count, 32 strands).

[0046] In this embodiment, when in use, firstly, the L-shaped bracket 5 is fixedly installed on the sofa frame through the fixing hole 6 and the corresponding fastener (bolt);

[0047] Specifically, there are two installation methods:

[0048] The first type, as shown in the appendix. Figure 7 As shown, the side of the L-shaped bracket 5 without the latch 7 can be fitted and fixed to one side of the sofa frame.

[0049] The second type is as shown in the appendix. Figure 8 As shown, the corner of L-shaped bracket 5 can be fitted against one corner of the sofa frame and secured.

[0050] Then, the I-beam 3 at one end of the cable tie body 1 is fitted onto the corresponding pin 7 through the insertion hole 4 and the eyelet 2, and the retaining plate 8 is exposed from the insertion hole 4 and the eyelet 2. Under the action of the elasticity of the cable tie body 1, one side of the pin 7 will fit against the inside side of the insertion hole 4, forcing the retaining plate 8 to be stuck on the outside side of the insertion hole 4 of the I-beam 3, thereby preventing the pin 7 from coming out of the insertion hole 4.

[0051] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
