Abstract

The utility model discloses a back pad for a backpack. The back pad comprises a pad body which is matched with the back part of the backpack in shape, wherein the pad body is a space cotton pad body; and a plurality of supporting convex granules are convexly arranged on a face of the pad body, contacting with the back of a user. According to the back pad for the backpack, the pad body is the space cotton pad body which can slowly rebound to absorb the pressure from articles in the backpack after being pressed by the articles in the backpack due to the slow rebounding characteristics of the space cotton, thus the impact force of the articles in the backpack to the user can be relieved, namely, the load of the backpack to the back of the user can be reduced to some extent, and the user cannot feel tired; in addition, a ventilation space formed by the spacing between every two supporting convex granules on the pad body is formed between the back of the user and the back part of the backpack, thus the friction heat produced between the back of the user and the back part of the backpack can be released timely through the ventilation spaces, the back of the user is less prone to sweat; and the back pad for the backpack is high in breathability.

Description

A kind of back pad for knapsack

Technical field

The utility model relates to stationery, particularly a kind of back pad for knapsack.

Background technology

Existing knapsack, its structure generally comprises indentured and band, band is fixed on indentured back, this knapsack, its one side contacting with toter's back is that indentured back is generally soft material and makes as cloth, be that indentured back is even surface, like this, toter indentured back when bearing can fit tightly with toter's back, the frictional heat that makes human body back and knapsack produce under moist and hot climatope cannot be discharged, thereby causes the sultry perspiration in toter back; Meanwhile, toter's back can directly be subject to the pressure of indentured interior items, causes toter's fatiguability.

In view of this, the inventor furthers investigate the above-mentioned defect of trousers, then in this case, produces.

Utility model content

The purpose of this utility model is to provide a kind of back pad for knapsack, to solve toter in prior art, easily makes the sultry perspiration in toter back and fatigable problem when bearing knapsack.

The technical solution of the utility model is such: a kind of back pad for knapsack, comprise and the suitable pad closing of knapsack back shape, above-mentioned pad is space wadding pad, and on the contact-making surface that contacts with toter back of above-mentioned pad, convexes with several and support protruding grain.

The protruding grain of above-mentioned support is one-body molded with above-mentioned pad.

Contact-making surface that above-mentioned pad contacts with toter toter back is provided with above-mentioned pad and matches, and will cover the gas-permeable nets layer of cloth of the protruding grain of each above-mentioned support in being covered in.

Above-mentioned gas-permeable nets layer of cloth is three-layer network layer of cloth.

Adopt after technique scheme, a kind of back pad for knapsack of the present utility model, because pad is space wadding pad, utilize the slow rebound characteristics of space wadding, make space wadding pad be subject to understand the pressure that slow resilience absorbs inside backpacks article after inside backpacks article pressure, alleviated the impulsive force that inside backpacks article are born toter, to a certain degree alleviated the heavy burden of knapsack to human body back, make toter's indefatigability; Simultaneously, utilize the protruding grain that respectively supports on pad to make to have by each and support the formed ventilation space of spacing between protruding grain between toter back and knapsack back, like this, the frictional heat producing between toter back and knapsack back can utilize this ventilation space to discharge in time, make toter back be difficult for perspiring, property is good thoroughly, thereby comparatively comfortable while making toter bear knapsack; The contact-making surface that contacts with toter toter back due to pad is again provided with pad and matches, and respectively support the gas-permeable nets layer of cloth of protruding grain in being covered in by covering, by absorbing sweat, the permeation functions of this ventilative screen cloth, can further improve the gas permeability of knapsack like this.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure:

Pad 1 supports protruding grain 11

Gas-permeable nets layer of cloth 2

The specific embodiment

A kind of back pad for knapsack of the present utility model, as shown in Figure 1, comprise and the suitable pad closing 1 of knapsack back shape, this pad 1 is space wadding pad, and on the contact-making surface that pad 1 contacts with toter back, convex with several and support protruding grain 11, it is one-body molded with pad 1 that each supports protruding grain 11, and contact-making surface that pad 1 contacts with toter toter back is provided with pad 1 and matches, and will covering the gas-permeable nets layer of cloth 2 respectively supporting in being covered in for protruding 11, this gas-permeable nets layer of cloth 2 is three-layer network layer of cloth.

A kind of back pad for knapsack of the present utility model, during use, is connected and is fixed on knapsack back by the outer of gas-permeable nets layer of cloth 2 and the stitching on all edges, knapsack back, and now pad 1 is tightly entrenched between knapsack back and gas-permeable nets layer of cloth 2.Compared with prior art, because pad 1 is space wadding pad, utilize the slow rebound characteristics of space wadding, make space wadding pad be subject to understand the pressure that slow resilience absorbs inside backpacks article after inside backpacks article pressure, alleviated the impulsive force that inside backpacks article are born toter, to a certain degree alleviated the heavy burden of knapsack to human body back, make toter's indefatigability; Simultaneously, utilize the protruding grain 11 that respectively supports on pad 1 to make to have by each and support the formed ventilation space of spacing between protruding grain 11 between toter back and knapsack back, like this, the frictional heat producing between toter back and knapsack back can utilize this ventilation space to discharge in time, make toter back be difficult for perspiring, property is good thoroughly, thereby comparatively comfortable while making toter bear knapsack; The contact-making surface that contacts with toter toter back due to pad 1 is again provided with pad and matches, and respectively support the gas-permeable nets layer of cloth 2 of protruding grain in being covered in by covering, by absorbing sweat, the permeation functions of this ventilative screen cloth, can further improve the gas permeability of knapsack like this.

In the utility model, the place, middle part of this pad 1 is concaved with a cavity (not marking in figure), in this cavity, be printed with a pictorial trademark layer (not shown in FIG.), like this, by this cavity, increase the ventilation space between toter back and knapsack back, strengthened gas permeability, the pictorial trademark layer in cavity can play the effect of decorating knapsack simultaneously.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
