The school bag of pupil contains the exercise book and teaching and auxiliary book of Chinese, mathematics, English, science, sports, art, society and main class, the total forest is also provided with more than ten books, and the dead weight of the water cup and the school bag is as light as six jin and seven jin, and the dead weight is more than ten jin. In order to solve the problems, currently, people adopt a pull rod type schoolbag or a strap type schoolbag, the pull rod type schoolbag can lighten the load of children on a flat road, but when the children touch a step or go upstairs and downstairs, the children have to carry the schoolbag over the step or go upstairs with one hand, and the children are particularly laboursome; the backpack type schoolbag has no elasticity, and the body of the child cannot stand up and is uncomfortable to walk up due to the fact that the backpack type schoolbag is heavily pressed on the back.
Disclosure of Invention
To the problem defect that exists among the above-mentioned prior art, the utility model aims to provide a student's elasticity formula schoolbag, this schoolbag combines the human developments that produce at the in-process of walking, makes the human body can keep straight reasonable state in walking, and it is also relatively light freely to walk to get up.
The technical scheme adopted for realizing the aim of the invention is as follows: an elastic schoolbag for students comprises a schoolbag main body and shoulder straps, wherein a front supporting frame and a back frame are sequentially arranged in an interlayer on the back surface of the schoolbag main body, and the middles of the front supporting frame and the back frame are connected through two push-pull tracks which are longitudinally and symmetrically arranged; the inner rail of the push-pull rail is fixedly arranged in the middle of the front support frame, the outer rail of the push-pull rail is fixedly arranged in the middle of the back frame, and elastic limiting devices are respectively arranged between the two longitudinal ends of the outer rail and the back frame; the inner track is provided with a connecting plate; the left shoulder strap and the right shoulder strap are respectively provided, and four ends of the left shoulder strap and the right shoulder strap are respectively connected with four corners of the back frame.
The elastic limiting device consists of a protective sleeve arranged on the back frame, and a magnet, a spring and a piston which are sequentially arranged in the protective sleeve.
The outer rail of the push-pull rail is embedded in the middle of the back frame and is 3-5 cm away from the elastic limiting devices at the two ends.
The utility model discloses a theory of operation of student's elasticity formula schoolbag:
the back of the elastic schoolbag is provided with a front support frame and a back frame, wherein the front support frame is connected with an inner layer of a back interlayer of the schoolbag main body to bear the weight of the schoolbag, the back frame is connected with an outer layer of the back interlayer of the schoolbag main body, when the schoolbag is carried on the back, the back frame is fixed on the back of a human body basically through braces, the front support frame and the back frame are connected through a push-pull track, and the track can slide up and down by 3-5 cm. The schoolbag body is characterized in that a human body generates dynamic natural vertical power in the walking process, the schoolbag body moves up and down along with the track, and a profile modeling motion state is formed between the schoolbag body and the back of a person by the elasticity of the elastic limiting devices at the upper end and the lower end of the protective sleeve, so that the schoolbag is easy and free to walk.
Compared with the prior art, the utility model discloses a student's elasticity formula schoolbag has following advantage:
1) the student bullet type weight-reducing schoolbag can keep a straight and reasonable state when a human body walks, and the student can walk easily and freely.

Detailed Description
The present invention will be further described with reference to the drawings and specific embodiments provided by the inventor.
Fig. 1 and fig. 2 show the elastic schoolbag for students from the angles of left view and back view respectively, which comprises a schoolbag body 1 and shoulder straps 2, wherein a front support frame 3 and a back support frame 4 are sequentially arranged in an interlayer at the back of the schoolbag body 1. The front support frame is connected with the inner layer of the back interlayer of the schoolbag body to bear the weight of the schoolbag, and the back support frame is connected with the outer layer of the back interlayer of the schoolbag body.
Fig. 3 is a schematic diagram of the internal structure of the back interlayer of the elastic schoolbag for students according to the present invention, wherein the front support frame 3 and the back support frame 4 are connected by two push-pull rails which are longitudinally and symmetrically installed; the inner rail 5 of the push-pull rail is fixedly arranged in the middle of the front support frame 3, the outer rail 6 of the push-pull rail is fixedly arranged in the middle of the back frame 4, and elastic limiting devices are respectively arranged between the outer rail 6 and two longitudinal ends of the back frame 4; the inner rail 5 is provided with a connecting plate 8; the shoulder straps 2 are arranged on the left and right respectively, and four ends of the shoulder straps are connected with four corners of the back frame 4 respectively.
