Description

Backpack

Technical Field

The utility model relates to the technical field of daily necessities, in particular to a backpack.

Background

The existing backpack braces are led out from the upper part of the backpack back to the side edge of the lower part of the backpack to form a carrying arc, and the length is adjusted by the adjusting pair so as to adapt to people with different heights and weights. In addition, the back is provided with a soft cushion to prevent the hard material in the bag from causing discomfort to the back.

However, the arc is carried directly on the shoulder without cushioning, which gives the shoulder a strong sense of weight when walking. The soft cushion at the back can not radiate back heat in seasons with higher air temperature, so that discomfort such as sweating at the back is caused.

The technical scheme adopted by the utility model is as follows:

the utility model provides a backpack, its characterized in that includes the knapsack body and sets up two braces in knapsack body back both sides, still sets up the backplate at the knapsack body back, the breach is left to the both sides shoulder position of backplate, and inside formation space, two braces stretch out from both sides breach department respectively, the lower segment of braces is made in knapsack body back lower part, and the braces middle section connects an elastic webbing in parallel, the length of braces middle section is located between elastic webbing relaxation state length and the taut state length, and the braces upper segment is connected to knapsack body side, forms the satchel arc, set up the back pad on the backplate, form the slot in the middle of the back pad.

Further, the middle groove of the back pad is in a cross shape, the back pad is divided into four pieces, and the upper and lower lengths of the upper back pad and the lower back pad are larger than those of the lower back pad.

Further, the four corners of the back pad are arc-shaped corners.

Further, the back pad is covered with a breathable net.

Further, the groove between the two back pads is in a horn shape with an upward opening.

Further, the notch at the shoulder position of the backboard is in a concave arc shape, and the top bottom and the side edges are sewn on the back surface of the backpack body.

Further, the upper sections of the two harnesses are connected together by a transverse section.

Further, the upper section and the transverse section of the brace are provided with convex layers, and the convex layers are coated with breathable nets.

Further, the height of the back pad is greater than 3cm.

The beneficial effects of the utility model are as follows:

(1) The backboard and the knapsack are separated, so that the processing and sewing difficulty is reduced;

(2) The elastic belt arranged on the back belt generates buffering force for the knapsack when walking, so that uncomfortable feeling of shoulders is reduced;

(3) The back pad on the back plate accords with human engineering, and the grooves provide heat dissipation channels for the back.

Detailed Description

The following describes the backpack according to the present utility model in detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, the backpack comprises a backpack body 1 and two braces 2 arranged on two sides of the back surface of the backpack body 1, wherein the lower sections 3 of the braces 2 are sewn on the lower part of the back surface of the backpack body 1, so that the braces 2 are firmly connected with the backpack body 1.

The middle section 4 of braces 2 connects in parallel an elastic belt 5, and the length of the middle section 4 of braces 2 is located between elastic belt 5 relaxation state length and taut state length, and when the knapsack was carried on the back, elastic belt 5 was taut, and when walking, the knapsack can cushion in elastic force scope of elastic belt 5, reduces the pull-down to the shoulder. The length of the middle section 4 of the back strap 2 limits the maximum extent to which the elastic strap 5 can be tensioned, preventing the elastic strap 5 from failing.

The upper sections 6 of the straps 2 are connected to the side edges of the backpack body 1 to form an arc, and the upper sections 6 of the two straps 2 are connected together through the transverse section 7. The upper section 6 and the transverse section 7 of the brace 2 are provided with a convex layer 8, and the convex layer 8 is covered with a ventilation net. The transverse section 7 can prevent the two braces 2 from falling off from the shoulder, and the convex layer 8 and the ventilation net enable the shoulder to reduce hard extrusion and increase comfort.

Referring to fig. 3, a back plate 9 is arranged on the back surface of the backpack body 1, notches 10 are reserved at shoulder positions on two sides of the back plate 9, a space is formed inside the back plate, two braces 2 extend out of the notches 10 on two sides respectively, and the lower section 3 and the middle section 4 of the braces 2 are hidden in the back plate 9. The notch 10 at the shoulder position of the back plate 9 is in a concave arc shape, and the top bottom and the side edges are sewn or adhered to the back surface of the backpack body 1.

The back plate 9 is provided with back pads 11, grooves 12 are formed in the middle of the back pads 11, the grooves 12 are cross-shaped, the back pads 11 are divided into four pieces, and the upper two back pads 11 are slightly larger than the lower two back pads 11. The four corners of the back pad 11 are arc-shaped corners, and the sewing is more convenient. The back pad 11 is covered with an air-permeable net, the groove 12 between the two back pads 11 is in a horn shape with an upward opening, so that the back pad 11 is just positioned at the shoulder blade position of a human body, and the groove 12 is positioned at the spinal depression position. The back pad 11 is set to a proper height, generally greater than 3CM, so that not only is the back soft when in contact with the backpack, but also the grooves 12 can dissipate heat in time.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
