[0021] The utility model will be further described below in combination with the drawings and examples.
[0022] A reinforced chain belt comprises a flat long strip-shaped base tape 1 and a chain tooth 2 sewn on the base tape 1 along the length direction, the base tape 1 is alternately sewn with not less than two longitudinal and transverse first auxiliary ropes 5 and second auxiliary ropes 6, the second auxiliary rope 6 is sewn on both sides of the base tape 1 with the chain tooth 2 as the center, and the first auxiliary rope 5 alternately passes through the second auxiliary rope 6 and is wound on the chain tooth 2 to fix the chain tooth 2.
[0023] Further, the two sides of the base cloth tape 1 are sewn with reinforcing cloth tapes, which pass through the chain teeth 2.
[0024] Further, the reinforcing cloth tapes include first reinforcing cloth tapes 3 sewn on the base cloth tape 1 and second reinforcing cloth tapes 31 sewn above the first reinforcing cloth tapes 3.
[0025] Further, the base cloth tape 1 and the second reinforcing cloth tapes 31 are both sewn with reinforcing cores 4, which pass through the chain teeth 2 and the first auxiliary ropes 5.
[0026] Further, the reinforcing core 4 includes a central rope and a plurality of auxiliary ropes spirally wound outside the central rope.
[0027] The first auxiliary ropes 5 and the second auxiliary ropes 6 pass through the reinforcing cloth tapes alternately.
[0028] The chain teeth 2 are made of a material with high strength and corrosion resistance.
[0029] A luggage zipper with reinforcing chain tape includes the reinforcing chain tape installed on the luggage and the zipper puller matched with the chain teeth 2.
[0030] In a specific embodiment, as shown in Figures 1-5 A luggage zipper with reinforcing chain tape includes the base cloth tape 1 in the shape of a flat strip sewn on the luggage and the chain teeth 2 sewn along the length of the base cloth tape 1, where the chain teeth 2 are made of a material with high strength and corrosion resistance. In a specific embodiment, the chain teeth 2 in a luggage can be made of metal materials such as copper, nickel, and stainless steel, which have high strength and corrosion resistance, thus effectively avoiding the situation that the chain teeth 2 are squeezed and deformed in use. In addition, the chain teeth 2 can also be made of high-strength nylon or polyester fiber, which has the characteristics of light weight and corrosion resistance, and is suitable for backpacks to reduce the weight of the backpack. The base cloth tape 1 is alternately sewn with a plurality of first auxiliary ropes 5 and second auxiliary ropes 6, which are sewn on both sides of the base cloth tape 1 with the chain teeth 2 as the center. The first auxiliary ropes 5 pass through the second auxiliary ropes 6 alternately and are wound around the chain teeth 2 to fix the chain teeth 2. Here, the first auxiliary ropes 5 and the second auxiliary ropes 6 are made of nylon or polyester materials with good wear resistance and flexibility, and their structures are mostly in the shape of a strip or a rope. By winding the chain teeth 2 in a crisscross manner through the first auxiliary ropes 5 and the second auxiliary ropes 6, the chain teeth 2 are fixed, which ensures that the chain teeth 2 can be arranged uniformly and stably. At the same time, the first auxiliary ropes 5 and the second auxiliary ropes 6 sewn on the base cloth tape 1 are integrated with the base cloth tape 1, which can prevent the edges of the zipper from being worn or torn, thus prolonging the service life of the zipper.
[0031] As shown in Figure 3 and Figure 4As shown in the drawings, the two sides of the base cloth tape 1 are sewn with reinforcing cloth tapes, the reinforcing cloth tapes pass through the sprocket 2, here, the reinforcing cloth tapes include a first reinforcing cloth tape 3 sewn on the base cloth tape 1 and a second reinforcing cloth tape 31 sewn above the first reinforcing cloth tape 3, the first reinforcing cloth tape 3 and the second reinforcing cloth tape 31 are sewn on the base cloth tape 1, so that the toughness of the cloth tape at the installation position of the sprocket 2 is strengthened, the situation that the cloth tape is torn due to the over-heavy weight of the bag or the extrusion is avoided, thereby prolonging the service life of the zipper and the bag.
[0032] As shown in the drawings, Figure 4 and Figure 5 The base cloth tape 1 and the second reinforcing cloth tape 31 are sewn with reinforcing cores 4, the reinforcing core 4 passes through the sprocket 2 and the first auxiliary rope 5, the reinforcing core 4 is arranged between the sprocket 2 and the base cloth tape 1 or the second reinforcing cloth tape 31, the reinforcing core 4 includes a center rope and a plurality of auxiliary ropes spirally wound outside the center rope body, the plurality of auxiliary ropes are tightly attached outside the center rope body, the reinforcing core 4 is fixed to the surface of the base cloth tape 1 or the second reinforcing cloth tape 31 through the second auxiliary rope 6, thereby providing stable tension in the longitudinal direction of the base cloth tape 1 and the second reinforcing cloth tape 31, at the same time, the reinforcing core 4 is attached to the inner wall of the sprocket 2, providing the sprocket 2 with lateral tension, thereby maintaining the stability of the sprocket 2.
[0033] As shown in the drawings, Figure 5 The first auxiliary rope 5 and the second auxiliary rope 6 pass through the reinforcing cloth tape alternately, this arrangement makes the sprocket 2 bear force evenly and stably.
