[0025] The technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments only represent some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort belong to the protection scope of the present application.

[0026] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The present application provides a zipper connecting assembly, which comprises a chain belt 1 for bearing each component, please refer to the description accompanying Figure 3 with the accompanying Figure 4In the length direction of the chain belt 1, first core wires 11 and second core wires 12 are arranged on both sides of the chain belt 1, wherein the first core wires 11 are connected with the connecting strips 3, and the second core wires 12 are connected with the plurality of chain teeth 2, and the chain teeth 2 are uniformly arranged on the second core wires 12. The chain belt 1 connects the chain teeth 2 and the connecting strips 3 as a whole. Further, the connecting strip 3 comprises a first clamping groove 32 and a clamping plate 31. The end of the chain belt 1 is arranged at the end of the connecting strip 3. The first core wire 11 is correspondingly arranged at the side port of the first clamping groove 32, and is moved along the length direction of the first core wire 11. The first core wire 11 is embedded in the first clamping groove 32, and gradually fills the first clamping groove 32 with the sliding of the first core wire 11. When the first core wire 11 reaches the other end of the first clamping groove 32, the assembly of the first core wire 11 and the first clamping groove 32 is completed. In the process of clamping the first core wire 11, the chain belt 1 slides between the clamping plates 31. The clamping plates 31 on both sides are pressed towards the side close to the chain belt 1, so as to avoid the slippage or twisting between the chain belt 1 and the connecting strip 3 in the subsequent processing process. In addition, after the chain belt 1 is connected with the clamping plate 31, a fixing member 4 is arranged on the end face of the connecting strip 3. The fixing member 4 is arranged between the clamping plate 31 and the chain belt 1, so as to strengthen the connection strength between the chain belt 1 and the connecting strip 3.

[0028] Please refer to the drawings in the description Figure 2 The second clamping groove 21 is arranged in each chain tooth 2, and the second clamping groove 21 is connected with the second core wire 12. The chain teeth 2 are uniformly arranged on the second core wire 12. The distance between the two adjacent chain teeth 2 is equal to the width of the chain tooth 2. The two clamping plates 31 are parallel to each other and are symmetrically connected on both sides of the clamping groove port. The distance between the clamping plates 31 is greater than the thickness of the chain belt 1, that is, there is a certain fitting allowance between the clamping plate 31 and the chain belt 1. In the process of arranging the chain belt 1, the chain belt 1 can be more easily clamped between the clamping plates 31. There is enough space between the clamping plate 31 and the chain belt 1 for coating adhesive. In addition, the first core wire 11 and the first clamping groove 32, and the second core wire 12 and the second clamping groove 21 are connected by interference fit. The first core wire 11 and the second core wire 12 are tightened in the first clamping groove 32 and the second clamping groove 21, so as to strengthen the connection strength between the chain tooth 2, the connecting strip 3 and the chain belt 1.

[0029] Preferably, the first core wire 11 and the second core wire 12 are coated with an anti-skid layer or texture on the outer side wall, further enhancing the grip of the first clamping groove 32 and the second clamping groove 21 on the first core wire 11 and the second core wire 12. The width of the clamping plate 31 is much smaller than the width of the chain strip 1, that is, after the clamping of the connecting strip 3 and the first core wire 11 is completed, the chain strip 1 connected with the clamping plate 31 has a part that can be bent and moved. When the zipper is pulled to make each chain tooth 2 engage, the bendable chain strip 1 provides sufficient flexibility for the chain tooth 2, which can be smoothly pulled to the corresponding engagement position during the pulling process. Further, the chain strip 1 is made of elastic material. When the load carried by the two ends of the connecting strip 3 is large, the chain strip 1 stretches and deforms and releases part of the load, so that the connecting structure between the connecting strip 3 and the chain strip 1 is damaged, or the engaged chain teeth 2 are separated, thereby increasing the service life of the zipper connecting assembly.

[0030] Please refer to the drawings in the description Figure 1 with the drawings Figure 2 The thickness of the first clamping groove 32 is greater than the distance between the two outer side walls of the clamping plate 31, forming a step surface at the connection between each clamping plate 31 and the clamping groove. A plurality of connecting holes 33 are arranged on the side of the clamping plate 31 close to the step surface along the length direction of the clamping plate. A fixing member 4 is arranged in each connecting hole 33, and the fixing member 4 also passes through the chain strip 1, locking the position of the chain strip 1 and the clamping plate 31, so that when the connecting strip 3 is pulled away from the side of the zipper, the connecting strip 3 and the chain strip 1 are separated. Further, a stop plate is arranged at the two ends of the fixing member 4, and the length of the fixing member 4 is slightly smaller than the distance between the end faces of the two clamping plates 31. That is, after the fixing member 4 is connected with the clamping plate 31, the stop plates at the two ends of the fixing member 4 clamp and fix the clamping plate 31 and the chain strip 1, so that the chain strip 1 and the clamping plate 31 do not slide relative to each other. A chamfer is arranged on the two side edges of the connecting hole 33. It should be noted that the maximum diameter of the chamfer is greater than the diameter of the stop plate, that is, the stop plate is embedded in the clamping plate 31, and the chamfer forms an annular inclined surface at the two ends of the connecting hole 33. During the process of arranging the fixing member 4, the chamfer automatically corrects the alignment deviation between the stop plate and the connecting hole 33, so that the fixing member 4 is not jammed or damaged due to installation deviation. In addition, after the stop plate is embedded in the chamfer, the axial tension of the rivet is converted into radial pressure through the chamfer inclined surface, so that the clamping force between the clamping plate 31 and the chain strip 1 is more evenly distributed, preventing local overload from causing deformation of the chain strip 1.

[0031] Preferably, an adhesive is coated between the first core wire 11 and the first clamping groove 32, and between the clamping plate 31 and the chain strip 1, so as to improve the connection strength between the components of the zipper connecting assembly. In addition, the connecting strip 3 and the chain strip 1 are both made of flexible material, so that the zipper connecting assembly can be bent arbitrarily to adapt to the shape of the bag port. It should be noted that the rigidity of the connecting strip 3 is greater than that of the chain strip 1.

[0032] The application also provides a luggage having the zipper connecting assembly, the luggage includes two symmetrical boxes (not shown in the figure), the openings of the two boxes can be butted against each other, the zipper connecting assembly is arranged on the edge of each box port, in an embodiment of the application, the edge of each box port is provided with a mounting groove, the inner wall of the mounting groove can be attached to the outer wall of the first clamping groove 32, the clamping plate 31 can be arranged in the port of the mounting groove, that is, after the zipper connecting assembly is connected to the box, the chain strip 1 connected with the clamping plate 31 extends out of the mounting groove, the two box ports are butted against each other, the zipper is pulled to make the teeth 2 engage with each other to complete the assembly of the box, preferably, the box structure is generally formed by sewing cloth, plastic injection molding and metal stamping, wherein the zipper connecting assembly can be processed in the process of processing the box port, the connecting strip 3 is integrally formed with the box, the production process is simplified, and the service life and the connecting performance of the luggage are improved.

[0033] It should be noted that the relative terms, such as first and second, in the present description are used only to differentiate one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.

[0034] The principle and implementation mode of the present application are described by using specific examples, and the above description of the examples is only used to help understand the method and the core idea of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the principle of the present application, the present application can be improved and modified in several ways, and these improvements and modifications also fall within the protection scope of the present application.
