Abstract

The utility model relates to the technical field of articles for daily use, concretely relates to knapsack auxiliary device who slows down excessive recurvation of back. This alleviate knapsack auxiliary device of excessive backturn in back includes the inclusion, and the back of inclusion is provided with the thrust body that is used for decomposing knapsack gravity, and the thrust body includes the inclined plane that back contact surface and relative back contact surface slope set up, and the inclined plane is connected with the back, and back contact surface and inclined plane are close to the contained angle that the back top is and set up for the acute angle, provide one kind and slow down the knapsack auxiliary device of excessive backturn in back.

Description

Backpack auxiliary device for slowing down excessive back bending

Technical Field

The utility model relates to the technical field of articles for daily use, concretely relates to knapsack auxiliary device who slows down excessive recurvation of back.

Background

At present, when the backpack is used, if the backpack is used for carrying too much things, the gravity of the backpack is too large when people carry the backpack, for comfort, the body of the backpack often leans forward to resist the gravity from the backpack, and the back of the backpack is excessively bent backwards, so that the appearance is affected.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: the defects of the prior art are overcome, and the backpack auxiliary device for slowing down excessive backward bending of the back is provided.

The utility model discloses a solve the technical scheme that its technical problem adopted and do: alleviate excessive back's of back knapsack auxiliary device, including the inclusion, the back of inclusion is provided with the thrust body that is used for decomposing knapsack gravity, the thrust body includes back contact surface and the inclined plane that sets up of relative back contact surface slope, the inclined plane is connected with the back, back contact surface and inclined plane are close to back top and are the contained angle and set up for the acute angle.

The utility model discloses set up, people are when the knapsack, and the thrust position is between the back and human back, and human back and back contact surface paste mutually, and the inclined plane links to each other with the back, and the inclined plane is the settlement angle with the back contact surface, and the people makes it slope through thrust body jack-up knapsack when the knapsack promptly, and the knapsack receives with inclined plane vertically holding power, and human back receives the pressure at perpendicular to back, thereby the back experiences forward and pushes away and feels and slow down the excessive back bend in back, reduces the influence to pleasing to the eye.

The thrust body is arranged in a triangular prism shape.

The edges and corners of the thrust body at the bottom of the back contact surface are arranged in a round angle mode. Avoid pressing against the back of the human body and causing discomfort.

The number of the thrust bodies is one, and the thrust bodies are located in the middle of the back face.

The thrust bodies are arranged in a number larger than 1 and are symmetrically arranged about the central axis of the back surface.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model provides a knapsack auxiliary device who slows down excessive recurvation in back changes the atress condition at knapsack and human back through the thrust body for the knapsack receive with inclined plane vertically holding power, and human back receives the pressure at perpendicular to back, thereby the back experiences forward pushing away and feels and slow down excessive recurvation in back, reduces the influence to pleasing to the eye.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the usage state of the present invention.

In the figure: 1. a bag body; 2. a back side; 3. a thrust body; 301. a back contact surface.

Detailed Description

The embodiments of the present invention will be further described with reference to the accompanying drawings:

examples

As shown in fig. 1 and 2, the backpack comprises a backpack body 1, a back surface 2 of the backpack body 1 is made of a hard material, a thrust body 3 for decomposing the gravity of the backpack is arranged on the back surface 2, the thrust body 3 comprises a back contact surface 301 and an inclined surface which is obliquely arranged relative to the back contact surface 301, the inclined surface is connected with the back surface 2, and an included angle formed by the back contact surface and the inclined surface close to the top of the back surface 2 is an acute angle.

The thrust body 3 is arranged in a triangular prism. The edges and corners of the thrust body 3 at the bottom of the back contact surface are arranged in a round angle. Avoid pressing against the back of the human body and causing discomfort.

The number of the thrust bodies 3 can be one, and the thrust bodies 3 are positioned in the middle of the back surface 2. The thrust bodies 3 can be arranged in a number larger than 1, and are symmetrically arranged about the central axis of the back 2, so that the uniform stress is ensured. The volume of the thrust body 3 is set according to the set number and the area of the back surface 2 of the backpack.
