Technical Field

[0001] The utility model relates to the technical field of luggage, in particular to a burden-reducing backpack. Background Art

[0002] Ordinary burden-reducing backpacks generally include a bag body, shoulder straps and a waist belt. For example, a spinal protection and weight-reducing backpack with a tension shoulder strap to prevent hunchback, disclosed in Chinese Patent Publication No. CN113615961A, the key points of its technical solution are: including: a bag body, a first shoulder strap, a second shoulder strap, a first elastic waist belt, a second elastic waist belt for pasting with the first elastic waist belt to surround the waist, a first tension shoulder strap for helping the shoulder to open, and a second tension shoulder strap for helping the shoulder to open; the first shoulder strap, the first elastic waist belt and the first tension shoulder strap are all arranged on one side of the bag body; the second shoulder strap, the second elastic waist belt and the second tension shoulder strap are all arranged on the other side of the bag body. This kind of elastic waist belt can better fit the bag body and the body, although it plays a certain role in reducing the burden, the waist belt does not have the function of a lumbar support. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a burden-reducing backpack, improve the function of the lumbar support piece, and enable the backpack to have the functions of burden reduction and spinal protection.

[0004] To solve the above technical problem, the technical solution of the utility model is: a burden-reducing backpack, including a bag body, two left-and-right arranged shoulder straps and lumbar support pieces arranged on both sides of the lower part of the bag body, the upper ends of the shoulder straps are connected to the upper part of the bag body, and the lower ends of the shoulder straps are rotatably connected to the lumbar support pieces. The principle of the utility model: the lower ends of the shoulder straps are connected to the bag body through the lumbar support pieces. When the user normally carries the backpack on both shoulders, the shoulder straps lift the lumbar support pieces upward. After the two lumbar support pieces are connected and locked through the buckle, not only can the lumbar support pieces be closely attached to the body, but also the upward-deformed lumbar support pieces can be pulled down to be straightened, so that the lumbar support pieces have the function of a lumbar support, achieving the effect of spinal protection and burden reduction.

[0005] As an improvement, the lower end of the shoulder strap is rotatably connected to the lumbar support piece through a connecting piece.

[0006] As an improvement, the connecting piece is a rivet or an I-shaped nail buckle.

[0007] As an improvement, an elastic band is arranged between the inner side of the upper part of the shoulder strap and the back panel of the bag body, one end of the elastic band is fixedly connected to the shoulder strap, and the other end of the elastic band is connected to the back panel of the bag body.

[0008] As an improvement, the two elastic bands corresponding to the two shoulder straps are an integral band, the integral band is in a V shape and passes through a buckle fixed on the back panel of the bag body.

[0009] As an improvement, the buckle is fixed on the back panel of the bag body through Velcro or sewing.

[0010] As an improvement, a waist belt is provided on the lumbar support piece, and the two waist belts corresponding to the two lumbar support pieces are connected by a buckle.

[0011] The beneficial effects brought by the present utility model compared with the prior art are as follows:

[0012] The shoulder strap lifts the lumbar support piece, enabling the lumbar support piece to function as a lumbar support. The elastic band can increase the stress points of the shoulder strap and make the bag body fit the human body more closely, enabling the backpack to have the function of reducing burden and protecting the spine. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be further described below in conjunction with the drawings in the specification.

[0015] As Figure 1 shown, a burden-reducing backpack includes a bag body 1, two shoulder straps 2 arranged left and right, and lumbar support pieces 6 provided on both sides of the lower part of the bag body 1. The shoulder strap 2 includes a shoulder belt and an adjustment webbing. The shoulder belt acts on the human shoulder. The upper end of the shoulder belt is connected to the upper part of the bag body 1, and the lower end of the shoulder belt is connected to the upper end of the adjustment webbing. The lower end of the adjustment webbing is rotatably connected to the lumbar support piece 6. In this embodiment, the lower end of the shoulder strap 2 is rotatably connected to the lumbar support piece 6 through a connecting member 7. The connecting member 7 is a rivet or an I-shaped nail buckle, so that the lower end of the adjustment webbing can be reliably connected to the lumbar support piece 6 and can rotate relative to the lumbar support piece 6. A waist belt is provided on the lumbar support piece 6, and the two waist belts corresponding to the two lumbar support pieces 6 are connected by a buckle. An elastic band 3 is provided between the inner side of the upper part of the shoulder belt and the back panel of the bag body 1. One end of the elastic band 3 is fixedly connected to the shoulder belt, and the other end of the elastic band 3 is connected to the back panel of the bag body 1. The two elastic bands 3 corresponding to the two shoulder straps 2 are an integral band. The integral band is in a V shape and passes through a loop 4 fixed on the back panel of the bag body 1. The loop 4 is arranged between the two shoulder straps 2. The loop 4 is fixed to the back panel of the bag body 1 by a magic tape 5 or sewing. The position of the loop 4 can be adjusted through the magic tape 5, so as to adjust the tension degree of the elastic band 3.

[0016] Principle of the present utility model: The lower end of the shoulder strap 2 is connected to the bag body 1 through the lumbar support piece 6. When the user normally carries the backpack on both shoulders, the shoulder strap 2 lifts the lumbar support piece 6 upward. After the two lumbar support pieces 6 are connected and locked by a buckle, not only can the lumbar support piece 6 be closely attached to the body, but also the upward-deformed lumbar support piece 6 can be pulled down to be straightened, enabling the lumbar support piece 6 to function as a lumbar support and achieving the effect of protecting the spine and reducing the burden.
