Portable schoolbag for study travel

Abstract

The invention relates to the technical field of schoolbags, and discloses a portable schoolbag for study travel, which comprises a schoolbag, the back of the schoolbag is fixedly provided with an interlayer, the outer wall of the interlayer is provided with an interlayer, and the outer wall of the interlayer is provided with a cushion layer; and fixing cylinders are arranged on the two sides of the interior of the interlayer, pistons are movably arranged on the inner walls of the fixing cylinders, springs are fixedly connected between the bottoms of the pistons and the inner bottom walls of the fixing cylinders, and straps are fixedly installed on the tops of the pistons. When a human body walks, the schoolbag has a transient suspension state in foot alternation, when the schoolbag is in the suspension state, the springs recover deformation and pull the pistons to move downwards, the pistons move downwards to enable air below the pistons to be inflated into the main air bags through the air pipes, and the main air bags are inflated to swell and softly attached to the back of the human body, therefore, the function of massaging the back can be achieved, meanwhile, when the main air bag makes contact with the back, the contact area is smaller, and the back is not prone to sweating.

Description

technical field [0001] The invention relates to the technical field of schoolbags, in particular to a portable schoolbag for research and travel. Background technique [0002] Study trips are organized by the school based on regional characteristics, age characteristics of students, and teaching content needs of various disciplines, and organize students to go out of the campus through collective travel, centralized board and lodging, expand their horizons, enrich their knowledge, and deepen their connection with nature in a different life. The closeness to culture increases the experience of the collective way of life and social public morality. Research travel inherits and develops the educational philosophy and humanistic spirit of traditional Chinese study tours and "read thousands of books and travel thousands of miles", and has become a new model of quality education. The content and new methods have greatly improved the self-care ability, innovative spirit and practic...

AI Technical Summary

Problems solved by technology

[0005] 1. The contact area between the above-mentioned schoolbag and the back is large, and the schoolbag fits the back completely and is easy to cover and sweat, causing the back to be wet with sweat. At the same time, it does not have the function of back massage;

[0006] 2. The contact area between the above-mentioned schoolbag and the back is poorly ventilated, and the lack of ventilation on the back will not only cause sweating on the back, but also cause prickly heat easily;

[0007] 3. The above-mentioned schoolbag does not have the function of drowning rescue. During the study trip, students often go to the water to watch. If they accidentally fall into the water, the traditional schoolbag cannot automatically float up and play the role of "rescue air bag";

[0008] 4. The above-mentioned schoolbag does not have the function of automatically holding an umbrella when it rains. During the study trip, it often encounters sudden rain. If there is no umbrella, the students will easily get wet and catch a cold. Traditional schoolbags do not have the " "Umbrella" function, unable to block the wind and rain;

[0009] 5. The above-mentioned schoolbags do not have the function of fall protection. During the research trip, students often go climbing. If they accidentally fall, the traditional schoolbags cannot protect the human body and play the role of "safety buffer airbag";
