In the figure: the bag comprises a bag body 1, braces 2, shoulder straps 3, wide-edge rubber bands 4, vertical woven belts 5, narrow-edge rubber bands 6, transverse woven belts 7 and an interlayer 8.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically connected, electrically connected or can communicate with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1, the present invention provides an embodiment: a spine-protecting burden-reducing schoolbag comprises a schoolbag body 1, shoulder straps 3 and back straps 2, wherein an interlayer 8 is arranged at the top of the schoolbag body 1, the end parts of the shoulder straps 3 are connected in the interlayer 8, so that the shoulder straps 3 can only move in the range of the interlayer 8, the number of the shoulder straps 3 is two, and the two shoulder straps 3 are symmetrically arranged along the axis of the schoolbag body 1.

The braces 2 are U-shaped, the left and right ends of the braces 2 are respectively and fixedly connected with the inner layer at the top of the bag body 1, and an elastic structure is arranged between the bottom of the braces 2 and the bottom of the bag body 1.

The elasticity structure includes vertical meshbelt 5, broadside rubber band 4 and narrow limit rubber band 6, the equal fixed connection in the intermediate position of 2 bottoms in braces of top of vertical meshbelt 5 and broadside rubber band 4, the equal fixed connection in the intermediate position of 1 bottom in the inclusion of the bottom of vertical meshbelt 5 and broadside rubber band 4, the length of vertical meshbelt 5 is greater than the length of broadside rubber band 4, the length that vertical meshbelt 5 exceeds than broadside rubber band 4 is no longer than 2 bottoms of braces to its length of being connected the port with inclusion 1, thereby all fix the length that is not more than vertical meshbelt 5 at the biggest tensile length of broadside rubber band 4, with the elasticity degree of protection broadside rubber band 4.

The both ends of narrow limit rubber band 6 are fixed connection respectively and set up in 1 bottom of inclusion and along 4 symmetries of broadside rubber band, the middle part fixed connection of narrow limit rubber band 6 is in 2 bottom positions of braces, the same horizontal plane of broadside rubber band 4 and narrow limit rubber band 6 department just is A style of calligraphy structures, make about 3 atress of baldric on both sides and the broadside rubber band 4 and the narrow limit rubber band 6 formation X type atress that form A style of calligraphy structure, be convenient for adjust the atress direction, reach the effect of protecting the spine. The bottom of the bag body 1 is fixedly provided with a horizontal braid 7, and the two ends of the narrow-side rubber band 6, the bottom end of the wide-side rubber band 4 and the bottom end of the vertical braid 5 are fixedly connected to the horizontal braid 7.

The specific implementation mode is as follows: when the schoolbag is used, a stress point is stressed and shunted at the bottom of the back strap 2, the wide-edge rubber band 4 and the narrow-edge rubber band 6 are in an A-shaped structure, the narrow-edge rubber band 6 and the shoulder strap 3 form X-shaped stress, and when the left shoulder strap 3 is stressed greatly, the right narrow-edge rubber band 6 can be tensioned along with the left stress by itself; when the right shoulder strap 3 is stressed greatly, the left narrow-side rubber band 6 can also automatically adjust the tension, so that the stress of the shoulder strap 3 is always kept in a balanced state, and the effects of reducing the load and protecting the spine are achieved.

When the left shoulder strap 3 and the right shoulder strap 3 are in a balanced state, the wide-side rubber band 4 and the vertical braid 5 exert the maximum stress and the decompression effect, when the weight of the schoolbag is increased, the wide-side rubber band 4 starts to stretch, and when the stretching length of the wide-side rubber band is equal to the length of the vertical braid 5, the stretching length is not prolonged any more, so that the stretching elasticity is restricted, the reverse elasticity effect is generated, the gravity of the schoolbag is in a suspension state in a short time, a part of gravity effect is offset, the decompression effect is achieved, and the health of students is prevented from being injured.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
