Description

Elasticity burden reduction knapsack

Technical Field

The invention relates to an elastic load-reducing backpack, belongs to the field of bags and has a certain load-reducing effect.

Background

The backpack is a daily necessity in life, generally carries more articles when going out, is very laboursome after long-term carrying time, is particularly heavier for students, can influence the body development of children after long-term heavy pressure, particularly has adverse effects on the spine compression of the children, is easy to cause fatigue when people carry the backpack outdoors in mountaineering, is very suitable for the needs of people, has various design schemes, some backpack is sold in the market, has good market reflection effect, has a common defect, is always rubbed with the back when the backpack floats up and down, has the main friction point of the waist position, and is very uncomfortable when clothes are worn less in summer or sweat occurs due to the fact that the backpack floats up and down, and has no isolation layer between the back of the backpack and the back of a human body, the backpack is directly rubbed on the back, such as: application No. 2019208508867, a weight-reducing suspension backpack with a flexible connection system of the pre-compression type, although able to solve the above mentioned friction problem, brings new drawbacks, the structure is too complex, the cost is very high, the added functional structure is heavy in weight itself, runs counter to the weight-reducing goal, the weight-reducing effect is not enough to offset the added weight, and the weight-reducing effect is not played on the whole.

Disclosure of Invention

The invention aims to provide an elastic load-reducing backpack with a reasonable structure, which aims to solve the defects and achieve the load-reducing purpose by adopting the vertical bounce between a partition plate and a back panel of the backpack and isolate the back from the back panel of the backpack by utilizing the partition plate, thereby achieving the load-reducing purpose and solving the problem of back friction.

Adopt and connect the baffle to constitute on the knapsack back panel, be provided with the horizontal meshbelt of back panel, the vertical meshbelt of back panel on the knapsack back panel, the baffle is provided with the horizontal meshbelt of baffle, the vertical meshbelt of baffle, the horizontal meshbelt of back panel is the cross with the vertical meshbelt of baffle and alternates and is connected, the vertical meshbelt of back panel is the cross with the horizontal meshbelt of baffle and alternates and is connected, the baffle is connected through the elastic webbing in the knapsack back panel, makes the knapsack reciprocating type up-and-down motion on the baffle under the effect of elastic webbing, reaches the effect of subtracting the burden.

The transverse woven belt of the back panel is arranged at the upper end of the back panel and is sewn and fixed at the position close to the straps along the vertical direction, and the longitudinal woven belt of the partition board penetrates through the transverse woven belt of the back panel and the back panel to form a cross.

The longitudinal back-panel mesh belt is arranged at the lower end of the back panel and arranged along two sides of the back panel of the backpack, the upper end and the lower end of the back panel are fixed by sewing, and the transverse partition plate mesh belt penetrates between the longitudinal back-panel mesh belt and the back panel to form a cross.

And the transverse woven belt of the partition plate is arranged at the lower end of the partition plate and is sewn and fixed along the vertical direction at the position corresponding to the longitudinal woven belt of the back panel.

The longitudinal mesh belt of the partition board is arranged at the upper end of the partition board, is arranged close to the position of the strap, and is fixed at the upper end and the lower end by sewing.

The upper end of the elastic belt is fixed with the partition board through sewing, and the lower end of the elastic belt is fixed with the rear panel through sewing.

Elastic webbing, lower extreme pass the back panel from the back panel trompil department and sew from the inside fixedly, the benefit that sets up like this lets back panel and baffle laminating inseparabler, hides elastic webbing more pleasing to the eye.

The elastic belt is provided with the limiting woven belt, so that the elastic belt is prevented from being excessively stressed and being damaged or weakened in elasticity.

The technical scheme of the invention is as follows: the backpack is characterized in that the backpack rear panel is connected with a partition board, the horizontal displacement of the panel and the partition board is limited by the criss-cross insertion of the woven tape, the backpack can freely move in the vertical direction, the elastic tape generates elasticity, the backpack is fluctuated up and down when a human body moves, and the burden reduction effect is achieved.

The invention has the beneficial effects that: simple structure is light, owing to adopt the meshbelt to connect, and convenient processing accords with case and bag processing technology, and the cost is lower, weight is lighter, sets up spacing meshbelt and takes effect to the guard action of elastic webbing, extension knapsack life.
