A kind of school bag with breathing padlock
Technical field
The present invention relates to a kind of student's school bag, particularly a kind of school bag with breathing padlock.
Background technology
At present, students in class business is heavy, and books are more and more, has increased the weight of the holding capacity of school bag, has also increased the weight of when the student endorses bag the shoulder pressure born, and the student is honest when growing up, and overweight pressure is influential to bone growth and development.And existing student's school bag, braces does not all have locker, and the pupil endorses, and wrapping to hold or carry in both hands holds up, pulls, and bears inconvenience, and the time has been grown simultaneously, easily causes pupil's pulled muscle, deformation of spinal column, affects figure, is unfavorable for body development, grows up healthy and sound.
Summary of the invention
The present invention is directed to defect and the deficiency of prior art, a kind of school bag of breathing padlock that has is provided.
Technical scheme of the present invention is:
A kind of have a school bag of breathing padlock, comprises inclusion and be located at the Braces hanged over tow shoulders at inclusion back, also comprises waistband, and described waistband is arranged at the bottom between two braces of described Braces hanged over tow shoulders; Respectively be provided with an accommodation zone on two braces of described Braces hanged over tow shoulders, respectively be provided with a sliding shackle on described accommodation zone, described sliding shackle moves up and down along accommodation zone; The two ends of described waistband respectively with accommodation zone on the sliding shackle detachable connection; Described waistband is provided with the slip padlock and breathes padlock; Described breathing padlock is by spacing band and telescopic band upper and lower superimposed composition, and spacing band is longer than telescopic band length.
Preferably, the elasticity that described spacing band is nonelastic band or spacing band is less than the elasticity of telescopic band.
Preferably, described inclusion back is provided with massage cushion; Several horizontal ventilating grooves are set on described massage cushion, and described massage cushion center is provided with the vertebra groove.
Preferably, described Braces hanged over tow shoulders is provided with safety alarm strip.
The invention has the beneficial effects as follows:
1, form three-legged structure by breathing snap close and Braces hanged over tow shoulders, from triangle mechanics angle, can alleviate school bag and content thereof the pressure to the student back, reach rectification figure, prevent deformation of spinal column, the effect reduced the heavy burdens;
But 2 free adjustment, both can change automatic telescopic with breathing health again according to the fat or thin realization of health multi-direction free adjustment up and down, eliminate the constraint sense of health;
3, with the hands do not entrust, both facilitated the student to bear school bag, avoided again pulled muscle.
