Abstract
The utility model relates to a schoolbag for preventing crookback, which comprises a bag body (1) and a pair of braces (2). The utility model is characterized in that the upper middle part of each of the braces (2) is provided with two transverse straps (3) which can be buckled with each other, and a pressure sensor alarm circuit (4) is arranged on the bag body (1). The utility model overcomes the disadvantages of single function and easy crookback formation of the existing schoolbag. The schoolbag for preventing crookback, which is disclosed by the utility model, has high practicality, and can alarm a user to correct the incorrect walking posture of the back of the user through the alarm circuit.
Description
Technical field
The utility model relates to a kind of school bag, and more particularly it is a kind of anti-bow-backed school bag.
Background technology
School bag is a kind of daily necessities, and students be unable to do without school bag every day, and the trip traveller also needs knapsack, has the of a great variety of school bag now, and the heavy burden ability is good, but function singleness easily causes long-term user, particularly student's hunchback.
Summary of the invention
The anti-bow-backed school bag of the utility model is seldom to consider the deficiency of user's health at existing product, and a kind of more practical novel school bag is provided, and it has overcome existing knapsack function singleness, easily causes bow-backed defective.
The purpose of this utility model is that general following measure reaches: anti-bow-backed school bag, and it comprises inclusion 1, braces 2, there are two cross bands that can fasten mutually 3 at the middle part on the described braces 2, and warning circuit 4 is arranged on inclusion 1.
In technique scheme, described warning circuit 4 is in series by power supply 4-1, switch 4-2, pressure sensor 4-3, alarm 4-4, and described warning circuit 4 is positioned at inclusion 1 back side interlayer.
The utility model is prevented that bow-backed school bag is practical, can be reported to the police through warning circuit and correct the incorrect walking posture in back.
Description of drawings
Fig. 1 is the structural representation of the anti-bow-backed school bag of the utility model;
Fig. 2 is the anti-bow-backed school bag warning circuit figure of the utility model.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing:
1 is that inclusion, 2 is that braces, 3 is that cross band, 4 is that warning circuit, 4-1 are that power supply, 4-2 are that switch, 4-3 are that pressure sensor, 4-4 are alarm among the figure.
The people buckles cross band when using school bag, and when correct set, then stressed by two braces, the school bag back does not stress, and the switch of pressure sensor warning device disconnects.
When poor form, i.e. front curve dorsad, because the effect of cross band, then human body back is to the school bag application of force, the switch closure of pressure sensor warning device, make circuit turn-on, pressure sensor work is so alarm gives the alarm, after pressure disappears, the switch automatic disconnection, after promptly posture was corrected, alarm disappeared.
Need to prove: to those of ordinary skill in the art, can also make some changes or distortion to the utility model under the prerequisite that does not change the utility model principle, this belongs to protection domain of the present utility model equally.
