Abstract
The utility model relates to a knapsack, which comprises a knapsack body with a plurality of galluses, and is characterized in that: a gasbag is arranged at the rear side of the knapsack body; the gasbag is connected with a gas-filled balloon through a windpipe. Compared with the prior art, the utility model has the advantages that: pliability of the back mat of the knapsack or a schoolbag can be adjusted by people according to tension and friction of the load of the knapsack or the schoolbag to waists of the people, so the knapsack can be closely stuck to the waists of the people effectively; meanwhile, tension of the load of the knapsack or the schoolbag to the waists can be balanced through the waists effectively so as to reduce the friction of the load of the knapsack or the schoolbag to the waists of the people when walking, enabling most comfort of the knapsack.
Description
Technical field:
The utility model relates to a kind of sack, particularly a kind of knapsack.
Background technology:
The back back pad of employed knapsack and children's school bag mainly uses chemical blowing materials such as PE cotton, sponge, EVA sheet to cause in the daily life at present, its effect all is a softness of utilizing these several prong materials, knapsack is distributed to entire back, waist to the pressure of human body, focus on the local location of human body back, waist the comfortableness during with raising people knapsack with the pressure of avoiding knapsack.But because human body back, waist is not straight, the back is than the past evagination of waist, and the PE cotton, sponge, chemical blowing materials such as EVA sheet are subjected to the restriction of physical property own, making knapsack, elastic force is limited during school bag, can not be adjacent to the waist of human body effectively, make can not be the effectively average knapsack of the whole waist of human body, school bag is to the pressure of waist, the friction that the hard thing that is loaded in knapsack or the school bag when walking to reduce human body produces waist, more can not make the user according to knapsack or school bag load-carrying to pressure that waist produced, the situation of frictional force is regulated knapsack voluntarily, the softness of school bag back pad is to reach best comfortableness.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of people to regulate the softness of knapsack, school bag back pad voluntarily to the pressure that waist produced, the situation of frictional force according to knapsack or school bag load-carrying, make knapsack can be adjacent to the waist of human body effectively, make can be the effectively average knapsack of the whole waist of human body, school bag pressure to waist, the friction that the hard thing that is loaded in knapsack or the school bag when walking to reduce human body produces waist is to reach the knapsack of best comfortableness.
The utility model is achieved in that and comprises the knapsack body that has braces, and its special feature is to be provided with an air bag at the back side of knapsack body, and air bag connects an aerating ballon by tracheae.During use, charge into the air of certain pressure in the air bag by aerating ballon.The back knapsack, air in the air bag is subjected to the extruding current downflow at the knapsack and the human body back side, air bag is changed according to rough surface, the human body back side, and be close to the back waist of human body, make human body back, waist on average bear the pressure of knapsack to the human body back side, avoid the long-time pressurized in a certain position, the human body back side and come to harm, disperseed the friction of hard thing that knapsack loaded, the best comfort when reaching back of the body knapsack the body local position.And knapsack is the time spent not, the air in the air bag can be drained, to reduce the volume of knapsack, with convenient collection and transportation.
Here, damage in order to protect air bag to avoid external object, air bag is arranged in the interlayer that has active open at the knapsack body back side.So both protected air bag, simultaneously, in case air bag is impaired, the air bag that can more renew by the opening on the interlayer.
Use for convenience, aerating ballon can be arranged on the knapsack base side and wear in the pocket of opening, and tracheae passes the knapsack internal layer aerating ballon and air bag are linked together.Like this, in people need regulate the knapsack that backs on the body during the air pressure of air bag, only need to take out aerating ballon in the pocket of knapsack side and just can regulate the air pressure of knapsack upper gasbag on one's body according to direct sensation with a hand.
Here, air bag can be separated into three or more than the pneumatophore that communicates, air bag is separated into more convenient gas behind a plurality of pneumatophores organically is distributed to air bag by the situation of pressurized corresponding position, makes the average pressurized in the rough surface of human body back waist avoid the long-time local compression in a certain position, the human body back side and strain.
The utility model compared with the prior art, have people and can regulate the softness of knapsack, school bag back pad voluntarily to the pressure that waist produced, the situation of frictional force according to knapsack or school bag load-carrying, make knapsack can be adjacent to the waist of human body effectively, make can be the effectively average knapsack of the whole waist of human body, school bag pressure to waist, the friction that the hard thing that is loaded in knapsack or the school bag when walking to reduce human body produces waist is to reach the advantage of best comfortableness.
