Lapped installation type anti-off school bag

Abstract

The invention relates to a school bag, in particular to a lapped installation type anti-off school bag. The lapped installation type anti-off school bag comprises a school bag body, upper straps, lower straps, insertion buckles and insertion buckle boxes. One end of each upper strap and one end of each lower strap are connected with the school bag body; connection lantern ring through holes are formed in the other ends of the upper straps; the other ends of the lower straps penetrate through the connection lantern ring through holes and then are movably sleeved with the insertion buckles; theinsertion buckles are matched with the insertion buckle boxes, and one side of each insertion buckle box is connected with the corresponding lower strap; quick lapped installation openings are formedin the other sides of the insertion buckle boxes. The lapped installation type anti-off school bag is clear in structure, buckling is conducted when the school bag is in use, the optimal using lengthcan be quickly reached; when the school bag is out of use, the hands press the insertion buckles at the same time, and length can be quickly greatly released; the school bag is provided with a safe protection structure, items placed in the school bag can be prevented from being damaged, some other unnecessary loss is reduced, the probability of releasing between the insertion buckles and the insertion buckle boxes is reduced, and the problems of inconvenience and force incoordination caused when a traditional insertion installation way is utilized by the school bag are solved.

Description

technical field [0001] The invention relates to a school bag, in particular to an anti-dropping school bag with leaning installation. Background technique [0002] Most of the existing school bags are fixed and adjusted by directly connecting the upper strap and the lower strap, which is simple and easy to use. However, when it is used, most of the size needs to be readjusted. Otherwise, in winter and other situations that require large movements and wearing, or people who like to adjust to a tight fit, they often choose to put the upper strap and the lower strap when taking it off. Adjust the length of the straps according to the length, and then adjust them tightly when using them. Moreover, the size of this adjustment is often different each time, and it is difficult for the left and right straps to be adjusted to a consistent length. Long-term use in this way can easily lead to high and low shoulders. [0003] The improved schoolbag uses a buckle and a buckle box dire...
