Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a luggage that is resistant to whitening and has high barrier properties. Background Technology

[0002] Bags and luggage are a general term for all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, suitcases, and various types of rolling suitcases. Bags and luggage that are resistant to whitening and have high barrier properties refer to the material's ability to resist the whitening phenomenon that occurs due to physical friction, scratches, or prolonged use. High barrier properties refer to the material's strong ability to block external environmental factors (such as moisture, oxygen, odors, and grease).

[0003] For example, the authorized announcement number "CN212488869U" is named a bag with an expansion function. It has a first expansion component and a second expansion component that open or close relative to the bag body. When in use, the loading space of the bag body 1 can be increased, more items can be placed, and it is more convenient to use. When not in use, it can be folded up without affecting the bag's volume and loading space, thus meeting people's needs.

[0004] The above-mentioned and existing technologies have the following drawbacks: the expansion ring fabric of the first expansion component of the bag will be folded and stretched multiple times. Due to the multiple folding and stretching of the expansion ring fabric, the expansion ring fabric is prone to damage and breakage, which reduces the lifespan of the bag. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bag that is resistant to whitening and has high barrier properties.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a whitening-resistant and highly barrier-free bag, comprising a first box and a second box. The second box has a lid sewn onto it by a zipper. The rear side of the lower surface of the first box is rotatably connected to a wheel. Two support legs are fixedly connected to the front side of the lower surface of the first box. A lifting rod is provided on the rear side of the upper surface of the first box. A connecting device is provided between the first box and the second box. The connecting device includes two fixing blocks. One of the two fixing blocks is located around the front side of the first box, and the other is located around the rear side of the second box. Each of the two fixing blocks has an installation groove on its facing side surface. A connecting cap is provided between the two fixing blocks. Both the front and rear surfaces of the connecting cap have sliders. Both sliders extend into the installation groove. A driving device is provided between each slider and the inner wall of the corresponding installation groove. A locking device is provided on the outer surface of each of the two fixing blocks.

[0008] Preferably, the driving device includes a first limiting block, which is disposed at the end of the slider away from the connecting cap, and a spring is connected between the connecting cap and the inner wall of one side of the mounting groove.

[0009] Preferably, the locking device includes a plurality of first male buckles and a plurality of base plates corresponding to them. The plurality of first male buckles are all disposed on one side surface of the front fixing block, and the plurality of base plates are all disposed on one side surface of the rear fixing block. A connecting post is provided on one side surface of the plurality of base plates, and a belt is rotatably connected to each of the plurality of connecting posts. A second limiting block is provided at one end of each of the plurality of connecting posts. A female buckle is provided on the side surface of the belt near the first male buckle, and the female buckle engages with the first male buckle.

[0010] Preferably, one side surface of the fixing block at the rear is provided with a plurality of second male buckles, and the plurality of second male buckles correspond one-to-one with a plurality of female buckles, and the female buckles are engaged with the second male buckles.

[0011] Preferably, the rear surface of the first housing is provided with multiple wear-resistant pads, the wear-resistant pads are made of polyvinyl chloride, the wear-resistant pads are in the shape of a frustum, the side surface of the wear-resistant pads is provided with multiple reinforcing ribs in a circumferential array, and the rear surface of the wear-resistant pads is provided with multiple wear-resistant particles.

[0012] Preferably, the rear surface of the first housing has a plurality of concealed grooves, each of which corresponds to a plurality of wear-resistant pads. The front surface of each of the plurality of wear-resistant pads has a protrusion, and the inner wall of the concealed groove is glued to the surface of the protrusion.

[0013] This utility model proposes a bag that is resistant to whitening and has high barrier properties. The advantages are as follows: When the bag needs to be expanded, a locking device removes multiple female buckles from their corresponding male buckles. Then, under the elastic action of two springs, the slider extends the volume of the first and second compartments, allowing the bag to hold more items. When expansion is not needed, the multiple female buckles are engaged with their corresponding male buckles, concealing the slider within the mounting groove, thus not affecting the bag's volume or loading space. In summary, the slider of this bag will not fold or extend, and will not break or crack after repeated expansions, extending the bag's lifespan. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-7 A type of anti-whitening and high-barrier bag includes a first body 1 and a second body 2. The second body 2 has a lid 3 sewn onto it by a zipper, which can be opened or closed by opening and closing the zipper. A wheel 4 is rotatably connected to the rear side of the lower surface of the first body 1, and two support legs 5 are fixedly connected to the front side of the lower surface of the first body 1, serving to support the bag. A lifting rod 6 is provided on the rear side of the upper surface of the first body 1. A connecting device is provided between the first body 1 and the second body 2, including two fixing blocks 7. One of the fixing blocks 7 is located around the front side of the first body 1, and the other is located around the rear side of the second body 2. Each of the two fixing blocks 7 has a mounting groove 8 on its facing side surface. A connecting cap 9 is provided between the two fixing blocks 7. Slider blocks 10 are provided on both the front and rear sides of the connecting cap 9, and both sliders 10 extend into the mounting groove 8. A driving device is provided between each slider 10 and the inner wall of the corresponding mounting groove 8. A locking device is provided on the outer surface of each of the two fixing blocks 7.

[0024] The driving device includes a first limiting block 11, which is located at the end of the slider 10 away from the connecting cap 9. A spring 12 is connected between the connecting cap 9 and the inner wall of the mounting groove 8.

[0025] The locking device includes multiple first male buckles 13 and multiple base plates 14 corresponding to them. The multiple first male buckles 13 are all located on one side surface of the front fixing block 7, and the multiple base plates 14 are all located on one side surface of the rear fixing block 7. A connecting post 15 is provided on one side surface of the multiple base plates 14. A belt 16 is rotatably connected to each of the multiple connecting posts 15. A second limiting block 17 is provided at one end of each of the multiple connecting posts 15. A female buckle 18 is provided on the side surface of the belt 16 near the first male buckle 13. The female buckle 18 is engaged with the first male buckle 13.

[0026] The rear fixing block 7 has multiple second male buckles 19 on one side surface, each corresponding to a single female buckle 18. The female buckles 18 engage with the second male buckles 19. This engagement between the second male buckles 19 and the female buckles 18 prevents the strap 16 from drooping when the bag is in its extended state, thus maintaining its aesthetic appeal.

[0027] The rear surface of the first case 1 is provided with multiple wear-resistant pads 20. These pads are made of polyvinyl chloride (PVC), which has excellent wear resistance, thus enhancing the wear resistance of the rear surface of the first case 1. Each wear-resistant pad 20 is frustum-shaped, with multiple reinforcing ribs 21 arranged in a circular array on its side surface. Multiple wear-resistant particles 22 are present on the rear surface of the wear-resistant pads 20. Multiple concealed grooves 23 are formed on the rear surface of the first case 1, each corresponding to one of the wear-resistant pads 20. Each wear-resistant pad 20 has a protrusion 24 on its front surface, and the inner wall of the concealed groove 23 is adhesively connected to the surface of the protrusion 24. The wear-resistant pads 20 enhance the wear resistance of the case. Their frustum-shaped design increases the contact area between the pads and the first case 1, and the adhesive connection between the concealed grooves 23 and the protrusions 24 prevents the pads from detaching.

[0028] Working principle: When the bag needs to be expanded, the locking device and the pulling of the belt 16 remove multiple female buckles 18 from their corresponding first male buckles 13. Then, the multiple female buckles 18 are engaged with their corresponding second male buckles 19. Under the elastic action of the two springs 12, the two fixing blocks 7 move in opposite directions, exposing the slider 10 to the outside. The slider 10 extends the volume of the first compartment 1 and the second compartment 2, allowing the bag to hold more items, such as... Figure 5 When expansion of the bag is not required, the locking device works by pulling the belt 16 to remove multiple female buckles 18 from their corresponding second male buckles 19. Then, by pressing the first and second boxes, the multiple female buckles 18 are engaged with their corresponding first male buckles 13, causing the slider 10 to be concealed within the mounting groove 8. This does not affect the bag's volume or loading space. Figure 1 In summary, the slider 10 of this bag will not fold or stretch, and will not break or crack after repeated expansion, thus extending the lifespan of the bag.
