[0001] The present invention relates to the field of luggage accessories, and in particular to a luggage middle frame connector, a luggage middle frame, and a suitcase Background Art

[0002] A suitcase, also known as a travel case, is a portable container for carrying and transporting items. It is widely used in travel, business trips, daily commuting, and professional needs in specific industries. The design of a suitcase usually takes into account factors such as easy carrying, capacity, durability, safety, and personalization

[0003] Common suitcases include two half - boxes, and the two half - boxes are relatively rotatable through pivoting to open and close the suitcase. After the two half - boxes are closed, they are connected by a zipper or a lock. To control the empty weight of the suitcase, the general box material is relatively thin. In order to form an effective seal after the boxes are buckled, a middle frame is generally installed on the two half - boxes

[0004] Currently, common zipper connectors are made of plastic, including a first fastener and a second fastener. The first fastener is adhesively bonded to one half - box, and the second fastener is adhesively bonded to the other half - box. Both the first fastener and the second fastener are installed with zipper teeth

[0005] Due to problems such as tensile stress (too many items in the box), temperature, and rain, the adhesive connection method has the problem of adhesive aging, resulting in a problem of decreased connection strength Utility Model Content

[0006] In order to improve the service life and reliability of luggage, the present application provides a luggage middle frame connector, a luggage middle frame, and a suitcase

[0007] In a first aspect, the present application provides a luggage middle frame connector. The connector is provided with a box - body connection groove for connecting with the luggage box - body. The two inner side walls of the box - body connection groove are an inner groove wall and an outer groove wall. The inner groove wall is used for fitting with the inner wall of the luggage box - body, and the outer groove wall is used for fitting with the outer wall of the luggage box - body. The connector and the luggage box - body are fixedly connected by fasteners or welding. The connector is provided with an inner zipper connection groove, and the opening of the inner zipper connection groove faces away from the box - body connection groove

[0008] By adopting the above technical solution, the connector is fixedly connected to the luggage box - body by fasteners or welding, effectively avoiding the problem of decreased connection strength caused by aging in the traditional adhesive connection method

[0009] Optionally, the fastener is a screw, a rivet, or a pin, and the fastener sequentially passes through the inner groove wall and the luggage box - body and is placed inside the outer groove wall

[0010] By adopting the above technical solution, both ends of the screw, rivet or pin are respectively connected to the inner groove wall and the outer groove wall, and the force-bearing structure of the screw, rivet or pin is a simply supported beam rather than a cantilever beam force-bearing structure, further increasing the connection strength between the connecting piece and the box body.

[0011] Optionally, the connecting piece is provided with an installation groove for accommodating a fastener.

[0012] By adopting the above technical solution, it is used to accommodate fasteners such as screws, rivets or pins, and plays a certain guiding role in installation.

[0039] The following further describes the present application in detail Figures 1-5 in conjunction with the accompanying drawings. Embodiment

[0040] A luggage, referring to Figure 1 , the luggage includes two half box bodies 100 and a luggage middle frame 300, and the two half box bodies 100 are relatively rotatable through a hinge 200. The hinge 200 can be a metal hinge or a hinge made of plastic or rubber.

[0041] The luggage middle frame 300 includes two connecting members 310, one of which is a first connecting member 311 and the other is a second connecting member 312. The first connecting member 311 is installed on the edge of one half box body 100, and the second connecting member 312 is installed on the edge of the other half box body 100.

[0042] The hinge 200 is fixedly connected to the half box body 100, thereby realizing the relative rotation of the two half box bodies 100.

[0043] In order to lock the two half box bodies 100, a luggage lock is installed on the side of the half box body 100 away from the hinge 200. The luggage lock can also be installed on the luggage middle frame 300.

[0044] Referring to Figure 1 and Figure 2, a box body connection groove 320 is formed on one side of the connecting member 310. The box body connection groove 320 is used to connect the connecting member 310 with the half box body 100, and the side wall of the half box body 100 is snapped into the box body connection groove 320. The two side walls of the box body connection groove 320 are an inner groove wall 321 and an outer groove wall 322. The inner groove wall 321 is attached to the inner wall of the half box body 100, and the outer groove wall 322 is used to be attached to the outer wall of the half box body 100, so that the connecting member 310 is pre-fixed to the half box body 100. Then, the connecting member 310 and the half box body 100 are fixedly connected through a fastener 400. The fastener 400 can be a screw, a rivet or a pin, and in this embodiment, a rivet is adopted. The fastener 400 sequentially passes through the inner groove wall 321, the half box body 100 and is placed in the outer groove wall 322. The two ends of the fastener 400 are respectively connected to the inner groove wall 321 and the outer groove wall 322. The force-bearing structure of the fastener 400 is a simply supported beam rather than a cantilever beam force-bearing structure, further increasing the connection strength between the connecting member 310 and the box body.

[0045] Refer to Figure 2 , a cavity 323 is formed in the outer groove wall 322. One end of the fastener 400 is placed in the cavity 323. The design of the cavity 323 increases the wall thickness of the outer groove wall 322 to effectively prevent the outer groove wall 322 from being completely penetrated, and at the same time, it will not excessively increase or decrease the weight of the connecting member 310.

[0046] Refer to Figure 2 , an installation groove 330 is formed in the connecting member 310. The fastener 400 is located in the installation groove 330, passes through the bottom of the installation groove 330, and extends to the box body connection groove 320. The installation groove 330 is used to accommodate the fastener 400, and also plays a certain guiding role in the installation of the fastener 400.

[0047] Refer to Figure 2 , a sealing strip 340 for closing the opening of the installation groove 330 is installed on the connecting member 310. The sealing strip 340 is a rubber strip or a plastic strip, and it is snapped at the opening of the installation groove 330. On the one hand, the sealing strip 340 has an anti-loosening effect on the fastener 400, and on the other hand, it covers the fastener 400 to improve the aesthetics.

[0048] Refer to Figure 1 , a lining 500 is arranged in the half box body 100. The lining 500 is connected to the connecting member 310 through an inner zipper 380. The inner zipper 380 includes an inner chain belt 381 snapped to the connecting member 310 and teeth 382 sewn to the edge of the lining 500. An inner zipper connection groove 350 (refer to Figure 2 ) is formed in the connecting member 310. The opening of the inner zipper connection groove 350 faces away from the box body connection groove 320. The inner chain belt 381 is snapped into the inner zipper connection groove 350. The inner chain belt 381 meshes with the teeth 382 to realize the installation of the lining 500.

[0049] Reference Figure 1 , the cross-sections of the two connecting members 310 in the luggage middle frame 300 are axially symmetrically arranged, that is, the box body connecting groove 320 of the first connecting member 311 and the box body connecting groove 320 of the second connecting member 312 are arranged with opposite opening directions. The inner zipper connecting grooves 350 of the first connecting member 311 and the second connecting member 312 have the same orientation.

[0050] A sealing strip 360 is clamped on the side wall of the first connecting member 311 facing the second connecting member 312. When the two half-box bodies 100 are closed, the sealing strip 360 is located between the first connecting member 311 and the second connecting member 312, thereby realizing the sealing of the luggage.

[0051] Example A luggage middle frame. The difference between this embodiment and the luggage middle frame disclosed in Embodiment 1 is that, with reference to

[0052] , this luggage middle frame is provided with an outer zipper 370 to replace the luggage lock to realize the closing of the luggage. Outer zipper connecting grooves 390 are provided at positions where the first connecting member 311 and the second connecting member 312 of the luggage middle frame 300 are close to each other, and the openings of the two outer zipper connecting grooves 390 are arranged facing each other. The two connecting members 310 of the middle frame are connected by the outer zipper 370, and the two outer chain tapes 371 of the outer zipper 370 are respectively inserted into the two outer zipper connecting grooves 390. Figure 3

[0053] The opening of the outer zipper connecting groove 390 is opposite to the opening direction of the box body connecting groove 320 and is in the same plane. After installation, the side wall of the luggage box body and the outer zipper 370 are in the same plane. When the luggage is closed by using the outer zipper 370, the pulling forces exerted on the connecting member by the side wall of the luggage box body and the outer zipper 370 are in the same plane. Therefore, the torque received by the connecting member is reduced, the force is more stable, and the service life of the connecting member is improved.

[0054] The opening of the outer zipper connecting groove 390 can also adopt other forms, such as Figure 4 , the opening of the outer zipper connecting groove 390 first faces the inside of the luggage box and then faces one side, forming an arrangement facing each other.

[0055] The inner zipper connecting groove 350 is located on the side of the installation groove 330 away from the opening direction of the box body connecting groove 320, that is, when the luggage is closed and the two connecting members 310 are in contact, the two inner zipper connecting grooves 350 are located between the two installation grooves 330. After the inner zipper 380 is installed in the inner zipper connecting groove 350 and connected to the inner lining 500, the installation groove 330 can be blocked, further improving the aesthetics. Example A luggage middle frame. The difference between this embodiment and the luggage middle frame disclosed in Embodiment 1 is that, with reference to

[0056] Figure 5 ​Figure 5 , an outer zipper 370 is provided on the middle frame of the luggage to replace the luggage lock to realize the closing of the suitcase.

[0057] At the positions where the first connecting member 311 and the second connecting member 312 of the middle frame 300 of the luggage are close to each other, abutting portions 313 are integrally formed. One abutting portion 313 forms a protrusion, and the other abutting portion 313 forms a groove. When the suitcase is closed, the two abutting portions 313 abut against each other. The abutting portions 313 are each provided with an outer zipper connection groove 390, and the openings of the two outer zipper connection grooves 390 extend outward and are arranged facing each other. The two connecting members 310 of the middle frame are connected by an outer zipper 370, and the two outer chain bands 371 of the outer zipper 370 are respectively inserted into the two outer zipper connection grooves 390. Embodiment

[0058] A middle frame of a luggage, the difference between this embodiment and Embodiment 2 is that, with reference to Figure 6 , outer zipper connection grooves 390 are provided at the positions where the first connecting member 311 and the second connecting member 312 of the middle frame 300 of the luggage are far away from each other, and the openings of the two outer zipper connection grooves 390 are arranged facing each other. After the outer chain band 371 is installed, the fastener 400 is installed. The fastener 400 first passes through the outer chain band 371 and then passes through the luggage body. Embodiment
