Description
Technical field
It the utility model is related to knapsack technical field, and in particular to one kind decompression knapsack.
Background technology
Backpack is as a kind of life articles for daily use, when people's both shoulders carry knapsack, the master that bears a heavy burden when shoulder belt is knapsack
Position is wanted, the both shoulders of people is produced fatigue for a long time, and then influence the health of user.Shoulder belt is really up to the mark to be made
The shoulder of people, which produces larger heavy burden sense, can even make one uncomfortable, and shoulder belt is excessively soft, and intensity is not enough to carrying weight.
In order to reduce pressure of the knapsack to shoulder, traditional way is usually in one secondary waist of the lower end of backpack installation
Band, fastens waistband in waist in knapsack.Method using installation waistband can only limitedly mitigate shoulders of human body load；And
When knapsack is equipped with weight, waistband can produce friction with hipbone, give sense of discomfort.
Effect occur preferably solves method at present：Depressurized using antigravity, improve user in knapsack process
In comfort level, the technical solution as disclosed in a kind of antigravity backpack (CN105747477A) of patent application document, lead to
Cross setting pressure reductor, first elastic webbing and length and fix band, user is during knapsack, and knapsack produces up-down vibration, to make
User brings buffering effect, can well alleviate since load is delivered to the feeling of stress of user's shoulder, be produced by elastic webbing
Raw screen resilience reduces the power that user needs to pay, and also mitigates the heavy burden of shoulder, allows user such as to place oneself in the midst of the sky of antigravity
Between, the comfort level of user is which thereby enhanced, makes user to walk not only brisk but also laborsaving.
But such technical solution reliable and stable can safely work to ensure elastic webbing, pressure reductor, fix band,
It must make the connection relation mode that pressure reductor, first elastic webbing, length are fixed between band, knapsack body to be fixedly connected.But
There can be very big difference since knapsack bears a heavy burden under different use environments, when above-mentioned component, particularly first elastic webbing exists
When can not be replaced under different use environments, bad user experience will also result in；Such as when the load of knapsack exceedes rated load,
First elastic webbing can gross distortion elongate, at this time knapsack body be in contact originally with (human body) back stress position may under
Drop, (human body) during knapsack, back may can not feel well since force is improper.
