Technical Field

[0001] This utility model relates to the technical field, specifically to a luggage zipper structure that is easy to assemble. Background Technology

[0002] Injection-molded bags are a type of bag product manufactured using the injection molding process. Its core characteristic is that molten plastic raw material is injected into a mold, and after cooling and solidification, a one-piece shell structure is formed. This process was first applied in the industrial field and has gradually become more widespread in the consumer market in recent years, especially in areas such as suitcases and tool cases.

[0003] Zippers on suitcases are prone to breakage when subjected to impact. Existing zippers are usually fixed to the mounting frame by sewing or gluing, making disassembly very difficult. Furthermore, after replacing a zipper, it is difficult to assemble the fabric on both sides of the zipper into the correct position. Summary of the Invention

[0005] Technical solution To achieve the above objectives, this utility model provides the following technical solution: A suitcase zipper structure for easy assembly includes a suitcase shell, a main zipper, an inner zipper, and a rigid plastic extrusion frame. The outer side of the rigid plastic extrusion frame has an open first slit. The two side ends of the suitcase shell are inserted into the first slit. The inner and lower sides of the rigid plastic extrusion frame have mounting grooves for installing the main zipper and the inner zipper, respectively. Clamping inserts are inserted into the mounting grooves. Each clamping insert includes two elastic pieces integrally formed at their rear ends, extending outwards at an angle. A clamping opening is provided between the two elastic pieces, clamping both ends of the main zipper. A locking slot is provided in the middle of the upper elastic piece. A forward-extending locking tongue is provided at the rear end of the locking slot. A locking protrusion, higher than the outer wall of the elastic piece, is provided on the upper side of the locking tongue. A raised wedge is provided on the upper side wall of the mounting groove. The raised wedge slides against the upper side of the elastic piece, and the locking protrusion engages with the raised wedge.

[0006] Preferably, the upper elastic sheet has a pressing notch on its front side, a pressing gap is provided between the front end of the locking tongue and the pressing notch, a pressing block is provided at the front end of the locking tongue, an inner groove is provided at the outer end of the mounting groove, and the pressing block is inserted into the inner groove.

[0007] Preferably, the elastic sheet has guide blocks on both sides of its rear end that slide with the mounting groove, and the width of the protruding wedge is less than the distance between the two guide blocks.

[0008] Preferably, the main zipper and the inner zipper are fixed with extrusion protrusions on both sides, a clamping block is provided on the front side of the clamping opening, the clamping block is provided with a clamping groove, the clamping groove is clamped on the extrusion protrusion with a concave-convex fit, and the clamping block is provided with anti-slip teeth.

[0009] Preferably, a decorative groove is provided on the outer side of the rigid rubber extrusion frame, a decorative rubber strip is installed in the decorative groove, and a stitch is provided between the decorative rubber strip, the box shell and the rigid rubber extrusion frame. Beneficial effects

[0010] This utility model provides a luggage zipper structure that is easy to assemble. It has the following advantages: In this invention, the clamping plug can be clamped to both sides of the main zipper. After being inserted into the mounting groove through the guide block, the protruding wedge blocks press the elastic sheet on the elastic sheet during the insertion process, causing the clamping opening to close and clamp the main zipper. At the same time, under the elastic force of the locking tongue, the clamping plug is fixed in the mounting groove, realizing the assembly and fixation of the main zipper. When disassembly is required, simply press the pressing block to make the locking protrusion move inward and disengage from the protruding wedge blocks, so that disassembly can be carried out smoothly.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] This utility model embodiment provides a luggage zipper structure that is easy to assemble, such as... Figure 1As shown, the device includes a case shell 1, a main zipper 2, an inner zipper 3, and a rigid rubber extrusion frame 4. Extrusion protrusions 5 are fixed to both sides of the main zipper 2 and the inner zipper 3. An open first slit is provided on the outer side of the rigid rubber extrusion frame 4. The two ends of the case shell 1 are inserted into the first slit. A decorative groove is provided on the outer side of the rigid rubber extrusion frame 4, and a decorative rubber strip 6 is installed in the decorative groove. A stitch is provided between the decorative rubber strip 6, the case shell 1, and the rigid rubber extrusion frame 4 to sew and fix the rigid rubber extrusion frame 4 onto the case shell 1. Mounting grooves for mounting the main zipper 2 and the inner zipper 3 are respectively provided on the inner and lower sides of the rigid rubber extrusion frame 4. Clamping plugs are inserted into the mounting grooves and clamp the two ends of the main zipper 2 and the inner zipper 3.

[0015] like Figure 2-3 As shown, the clamping plug includes two elastic pieces 7 integrally formed with their rear ends connected. The rear ends of the two elastic pieces 7 are fixed, and their front ends extend outward at an angle. A clamping opening for clamping the main zipper 2 and the inner zipper 3 is provided between the two elastic pieces. A clamping block is provided on the front side of the clamping opening. A clamping groove is provided on the clamping block. The clamping groove clamps the extruded protrusion 5 with a concave-convex fit. The clamping block is provided with anti-slip teeth. By squeezing the two elastic pieces 7, the clamping opening can be closed and clamped on both sides of the main zipper 2 and the inner zipper 3. The main zipper 2 and the inner zipper 3 can be assembled and positioned through the clamping groove. Guide blocks 8 are provided on both sides of the rear end of the elastic pieces 7, which slide and cooperate with the mounting groove.

[0016] A locking slot is provided in the middle of the upper elastic piece 7. A locking tongue 9 extending forward is provided at the rear end of the locking slot. A locking protrusion 10 higher than the outer wall of the elastic piece 7 is provided on the upper side of the locking tongue 9. The locking protrusion 10 protrudes from the outer wall of the elastic piece 7 due to the elastic force of the locking tongue 9. A protruding wedge 11 is provided on the upper side wall of the mounting groove. The protruding wedge 11 slides and abuts against the upper side of the elastic piece 7. The width of the protruding wedge 11 is less than the distance between the two guide blocks 8. The protruding wedge 11 can abut against the upper side of both the elastic piece 7 and the locking tongue 9 at the same time. The protruding locking protrusion 10 is engaged with the protruding wedge 11 under the elastic force, which can fix the clamping plug in the mounting groove and complete the assembly.
