Description

Technical Field

[0001] This utility model relates to the field of backpack technology, and in particular to a backpack with a vertical opening in the middle. Background Technology

[0002] Backpacks are the core carrying tool for daily commuting, business trips and outdoor activities. The main body consists of the bag body, shoulder straps and zippers. By carrying it on the shoulder, the hands are freed. Traditional models usually have horizontal openings on the top or sides, and the internal capacity is fixed. When carrying it, the weight is concentrated on the shoulders, which can easily cause shoulder pain and back swelling after walking for a long time. In addition, the lack of lumbar support causes the bag body to sway, affecting the stability of walking.

[0003] Most existing backpacks do not have a lumbar support at the back, and the entire load is transferred to the trapezius muscles through the shoulder straps. When walking, the backward tilting torque of the bag continuously pulls on the shoulders and back, which can easily cause muscle fatigue and soreness. Although some products have added lumbar pads, they use sewn or hidden pockets for semi-fixation, which makes it inconvenient to use the lumbar support according to the actual weight of the backpack. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a backpack with a vertical opening structure in the middle.

[0005] This utility model is achieved using the following technical solution: a backpack with a vertical opening in the middle, comprising a backpack body, a vertical zipper on the front of the backpack body, a cloth bag cover fixedly connected to the rear end of the backpack body, a sleeve post sleeved inside the cloth bag cover, a waist support fixedly connected to the surface of the sleeve post, a claw fixedly connected to the end of the waist support away from the sleeve post, a connecting strap one fixedly connected to the surface of the sleeve post, a female buckle sleeved to the end of the connecting strap one away from the sleeve post, a female buckle snapping into the inside of the female buckle, and a connecting strap two fixedly connected to the end of the female buckle away from the female buckle.

[0006] Through the above technical solution, by setting up the backpack body, vertical zipper, cloth bag cover, sleeve post, waist support, claw, connecting strap one, female buckle, connecting strap two, and female buckle, the shoulder straps bear the main weight when carried, the waist support and claw wrap around the waist and are locked by the female and male buckles, forming a shoulder-waist joint load-bearing structure. When the load is light, the sleeve post can be pulled out from the cloth bag cover by tearing the Velcro, so that the waist support and claw are separated from the backpack as a whole, and the backpack returns to its normal lightweight state. Thus, it can achieve the effect of freely switching the load-bearing mode according to the load, and balancing heavy load stability and lightweight simplicity.

[0007] As a further improvement to the above solution, the vertical zipper is set perpendicular to the bottom of the backpack body.

[0008] With the above technical solution, the vertical zipper is arranged perpendicular to the bottom of the backpack body, the zipper path is the shortest and it is located in the center, so the main compartment can be fully opened by pulling it open with one hand at a time.

[0009] As a further improvement to the above solution, the number of the ring claws is set to two, and the two ring claws are symmetrically distributed around the center of the front of the waist support, and the material of the sleeve is filled cotton.

[0010] With the above technical solution, the two ring claws are symmetrically distributed around the center of the front of the lumbar support, so that the force is evenly distributed when hugging the waist, avoiding unilateral compression, thereby improving the fit and preventing the lumbar support from slipping.

[0011] As a further improvement to the above solution, the end of the connecting strap away from the buckle is fixedly connected to the surface of the sleeve post.

[0012] Through the above technical solution, the two ends of the connecting strap are fixed to the surface of the buckle and the sleeve respectively, forming a closed force ring. After fastening, there is no free end shaking, which achieves the effect of eliminating slapping noise and improving wearing comfort.

[0013] As a further improvement to the above solution, one end of the sleeve is fixedly connected to a hook and loop fastener, and the other end of the sleeve is fixedly connected to a hook and loop adhesive fastener.

[0014] Through the above technical solution, the two ends of the sleeve are respectively provided with hook and loop fasteners and adhesive surfaces, so that the sleeve can roll up and stick itself, achieving the effect of fixing the rolled state and preventing loosening when storing.

[0015] As a further improvement to the above solution, the hook and loop fastener's barbed side is adapted to the hook and loop fastener's adhesive side.

[0016] Through the above technical solution, the hook and loop fastener's serrated and adhesive sides are matched to each other, ensuring uniform peel force after bonding and maintaining a reliable connection even after repeated opening and closing.

[0017] As a further improvement to the above solution, cup sleeves are fixedly connected to both the left and right ends of the backpack body, a hanging strap is fixedly connected to the top of the backpack body, a carrying strap is fixedly connected to the top of the backpack body, and a shoulder strap is fixedly connected to the rear end of the backpack body.

[0018] Through the above technical solutions, the cup sleeve provides an independent external storage space, the hanging strap is for temporary hanging, the carrying strap is for short-distance carrying, and the shoulder strap enables double-shoulder carrying, thus achieving the effect of meeting multiple scene switching and improving ease of use.

[0019] As a further improvement to the above solution, the number of shoulder straps is set to two, and the two shoulder straps are symmetrically distributed around the center of the rear surface of the backpack body.

[0020] With the above technical solution, the two shoulder straps are symmetrically distributed around the center of the rear surface of the backpack body, so that the force on the shoulders is even, avoiding unilateral pressure, and achieving the effect of reducing fatigue and maintaining the balance of the backpack.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model incorporates a cloth bag cover, a sleeve post, a waist support, loop claws, a first connecting strap, a female buckle, a second connecting strap, and a male buckle. When carrying the backpack, first, the shoulder straps are placed against the shoulders, then the waist support is placed against the waist. The two loop claws are then moved to symmetrically encircle both sides of the waist. Finally, the second connecting strap is tightened and the male buckle is engaged with the female buckle, ensuring that the waist support and loop claws fit securely against the user's waist. This transfers some of the backpack's weight from the shoulders to the pelvis, reducing shoulder pressure and improving carrying stability.

[0022] This utility model, by setting up a hook and loop fastener and a hook and loop adhesive side, allows the lumbar support to be removed simply by tearing the hook and loop fastener and then pulling out the sleeve to remove the lumbar support and the ring claw from the bag. The process can be completed without tools and with one hand, achieving the effect of quickly assembling and disassembling the lumbar support according to the load, realizing multiple uses in one bag, and improving the flexibility of use.
