Description

Technical Field

[0001] The utility model relates to a backpack elastic load-reducing system, belonging to the field of bags. Background Art

[0002] Backpack is a general term for backpacks carried on the shoulders. Its main features are easy to carry, freeing your hands, light weight, good wear resistance, and providing convenience for going out. The back of a general backpack is a 3MM pearl cotton breathable panel. The simplest drawstring bag type backpack has no cushioning material except the material of the backpack itself. This structure cannot move up and down relatively when the user carries it, and cannot play a buffering role. Carrying it for a long time will make the user's shoulders feel tired.

[0003] CN202120362489.2 discloses a load-reducing backpack with a buffer amplitude adjustment function, including a back width and two shoulder straps connected to the back width, the upper part of the shoulder straps is connected to the back width through an elastic member, and a limiting belt assembly is provided between the shoulder straps and the back width to limit the relative movement distance between the upper part of the shoulder straps and the back width, and the limiting belt assembly includes a first limiting belt fixed on the back width, a second limiting belt fixed on the shoulder strap, and a length adjustment buckle provided between the first limiting belt and the second limiting belt and adjusting the limiting length of the limiting belt assembly. During the process of carrying and walking, due to the provision of the elastic member, the upper part of the shoulder strap can move up and down relative to the back width during walking, which can buffer the force of the backpack on the shoulders and improve the comfort of the user. A limiting belt assembly is provided between the shoulder strap and the back panel to limit the relative movement distance between the upper portion of the shoulder strap and the back panel. The buffering amplitude of the shoulder strap can be set by the limiting belt assembly. Although this structure realizes the functions of length adjustment and buffering, the weight of the backpack is still mainly applied to the shoulders of the user, which will still cause shoulder fatigue when carried for a long time. Summary of the invention

[0004] In view of this, the utility model provides a backpack elastic load-reducing system to reduce the pressure of the backpack on the shoulders of the user during exercise, making the backpack more labor-saving during the carrying process.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A backpack elastic load-reducing system comprises a back pad and a back strap, a height-limiting belt is transversely arranged on the upper part of the back pad, an inverted "V"-shaped fixing belt is arranged below the height-limiting belt, and the upper end of the fixing belt is overlapped and fixed with the height-limiting belt;

[0007] The shoulder strap comprises two strap bodies, a connecting piece and a plurality of elastic straps. The upper ends of the two strap bodies respectively pass through two clamping positions formed by the back pad and the fixing strap and are integrally connected with the upper end of the connecting piece. The lower end of the strap body is fixedly connected with the lower end of the back pad. One end of the elastic strap is fixedly connected with the lower end of the back pad, and the other end is fixedly connected with the lower end of the connecting piece.

[0008] The back pad also includes a tension plate, the upper and lower ends of the tension plate are respectively fixed on the back pad, the upper end of the tension plate is superimposed and fixed with the height limiting belt, the lower end is superimposed and fixed with the elastic belt, and the middle section of the elastic belt is fixedly connected to the tension plate.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Further, the elastic belt includes a left elastic belt, a right elastic belt and a middle elastic belt.

[0011] Furthermore, it also includes two height-limiting fixing belts, one end of the two height-limiting fixing belts is respectively fixedly connected to the back pad, and the other end is respectively connected to the two belt bodies through the adjustment buckles on the belt bodies.

[0012] Furthermore, a chest buckle is connected between the two belt bodies.

[0013] The beneficial effects of the utility model are:

[0014] The setting of the elastic belt allows the backpack to move relatively during the user's movement to buffer the pressure of the backpack on the user's shoulders. At the same time, the setting of the tension plate forms a suspended structure, so that the backpack does not stick to the user's back after being carried, further buffering and dispersing the pressure, thereby improving the user's comfort. In addition, a height-limiting fixing belt is provided so that the backpack can be relatively adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 As shown, the backpack elastic load-reducing system includes a back pad and a shoulder strap.

[0023] like Figure 3 A height limiting belt 1 is horizontally arranged on the upper part of the back cushion, an inverted "V"-shaped fixing belt 2 is arranged below the height limiting belt 1, and the upper end of the fixing belt 2 is superimposed and fixed with the height limiting belt 1;

[0024] like Figure 4 The shoulder strap comprises two strap bodies 3, a connecting piece 4 and a plurality of elastic straps 5. The upper ends of the two strap bodies 3 are respectively connected to the upper end of the connecting piece 4 after passing through the two clamping positions formed by the back pad and the fixing strap 2. The lower end of the strap body 3 is fixedly connected to the lower end of the back pad. One end of the elastic strap 5 is fixedly connected to the lower end of the back pad, and the other end is fixedly connected to the lower end of the connecting piece 4.

[0025] The back pad also includes a tension plate 6, the upper and lower ends of which are respectively fixed on the back pad, the upper end of which is superimposed and fixed to the height limiting belt 1, and the lower end is superimposed and fixed to the elastic belt 5, and the middle section of the elastic belt 5 is fixedly connected to the tension plate 6.

[0026] In another embodiment of the present invention, the elastic band 5 includes a left elastic band, a right elastic band and a middle elastic band.

[0027] In another embodiment of the present invention, two height-limiting fixing belts 7 are further included, one end of the two height-limiting fixing belts 7 is respectively fixedly connected to the back pad, and the other end is respectively connected to the two belt bodies 3 through the adjustment buckles 8 on the belt body 3.

[0028] In another embodiment of the present invention, a chest buckle 9 is connected between the two belt bodies 3 .

[0029] With the above technical solution, after the user carries the backpack, the elastic belt 5 is pressed down and stretched by the weight of the backpack, the backpack falls to the connection piece 4 and the fixing belt 2 abuts, the backpack leans back, and a gap is formed between the back pad and the tension plate 6, such as Figure 2 As shown, during exercise, the elastic belt 5 drives the backpack to move up and down to form a buffer, thereby alleviating the fatigue of the user's shoulders.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
