Embodiment 1

[0055] see Figure 1-Figure 4 , a portable schoolbag for research and travel, comprising a schoolbag 1, a mezzanine 2 is fixedly installed on the back of the schoolbag 1, an outer wall of the interlayer 2 is provided with a partition 3, and an outer wall of the interlayer 3 is provided with a cushion 4;

[0056] Both sides of the interlayer 2 are provided with a fixed cylinder 6, the inner wall of the fixed cylinder 6 is movable with a piston 7, a spring 8 is fixedly connected between the bottom of the piston 7 and the inner bottom wall of the fixed cylinder 6, and the top of the piston 7 is fixedly installed. There is a back strap 5, one end of the back strap 5 is fixedly installed on the top of the piston 7, and the other end of the back strap 5 passes through the fixed cylinder 6 and the interlayer 2 and is fixedly installed on the outer wall of the cushion layer 4;

[0057] The outer walls of the two fixed cylinders 6 are all connected with air pipes 9, and the installatio...

Embodiment 2

[0061] see Figure 1-Figure 6 , on the basis of Embodiment 1, side bags 12 are provided on opposite sides of the two main air bags 10, and side plates 13 are fixedly installed on opposite ends of the two side bags 12, and the two side plates 13 are slidably arranged on the two sides. Between two sealing plates 14, two sealing plates 14 are fixedly installed on the outer wall of the interlayer 3;

[0062] The outer wall of the cushion layer 4 is provided with an air outlet 15, and the opening position of the air outlet 15 corresponds to the installation position of the two sealing plates 14;

[0063] When the main airbag 10 is inflated, the side bag 12 is also inflated, and the side bag 12 is inflated to make the two side panels 13 close to each other; The air loss makes the two side panels 13 far away from each other;

[0064] When the two side plates 13 were far away from each other, the external wind was sucked between the two side plates 13 through the air outlet 15, and ...

Embodiment 3

[0067] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 , on the basis of Embodiment 1 and Embodiment 2, through-pipes 16 are connected through the bottoms of the two fixed cylinders 6, and first control valves 17 are arranged inside the two through-pipes 16, and the two through-pipes 16 A compressed gas tank 18 is connected through the bottom;

[0068] The outer wall of the compressed gas tank 18 is covered with an elastic rubber pad, and the outer walls of the interlayer 3 and the cushion layer 4 are respectively provided with a first tank tank 19 and a second tank tank 20 that match the compressed gas tank 18. The compressed gas tank 18 It is clamped on the inner wall of the first tank 19 and the second tank 20, and the compressed gas tank 18 covered with an elastic rubber pad protrudes from the first tank 19 and the second tank 20, and can just hold The waist of the human body makes the schoolbag 1 more comfortable to carry;

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...
