Description
Technical field
This utility model is related to study article technical field, specially a kind of child's knapsack with safety lock.
Background technology
For the student that each is gone to school, knapsack is one of necessary article.At present, the knapsack that student uses is most to be soft
Knapsack, although soft knapsack can arbitrarily be placed, can reduce and take up room, but soft knapsack has some in use asks
Topic.The books placed in the knapsack of student and other stationery are relatively more, even if student is neat by books before shouldering knapsack at present
Be stacked in knapsack, but in the presence of the action of gravity in books and other stationery itself and knapsack rock, books and other
Stationery can disorderly be put, and easily leads to part books to deform in this case, and particularly relatively thin books deformation can be more severe, this
Also the part page of part books is easily led to by knuckle or to be torn outward, more than this, I haven't seen you for ages affects the normal use of books；Due to
In knapsack, the books placed and other stationery are relatively more, and knapsack therefore can be led to too heavy, for lower student,
Height is smaller, and not only the pressure of the knapsack of back cannot balance and be scattered in back and waist, and the shoulder that increased student bears load,
Have impact on the spinal column of student, and can lead to student that back cannot be kept straight and upright, hunchback can be caused in the course of time, this is for student
Body development be extremely unfavorable；In addition, opening or closing of knapsack would generally adopt zipper, but during slide fastener uses
Often it is susceptible to stripped thread phenomenon, reduce knapsack service life.
