Abstract
The utility model discloses a schoolbag with a device for an over-weight alarm, which is provided with an overweight alarm circuit; an elastic metal sheet (5) is arranged on a lifting handle of a schoolbag; a metal strip (6) is provided with an insulation jacket; the metal strip (6) is arranged in a small hole on the elastic metal sheet (5); a power (1), a speaker (2), a voice integrated package (3) and a signal lantern (4) presents a series connection state; one end of the series circuit is connected with the elastic metal sheet (5) and the other end is connected with the metal strip (6). The elastic metal sheet (5) is contacted and connected with the metal strip (6) when the stress reaches certain value, and then the alarm circuit is switched on. The utility model has convenient operation, is favorable to the physical and mental health of the student and can excite the learning interest of the student.
Description
The utility model relates to a kind of school bag that sends audible and visible alarm when overweight.
In today of quality-oriented education, the head of a family, teacher wish that the student is the people of a development in an all-round way, to adapt to demands of social development, require them to learn more knowledge and technical ability, but also therefore cause the school bag of student's back more and more heavier, the whole society all lightens the students' load strong the appealing, the overweight phenomenon of control student's school bag.
The purpose of this utility model provides the school bag that can send audible and visible alarm when a kind of weight surpasses certain value.
The technical solution of the utility model is: overweight alarm school bag, comprise braces, carry hand and pocket, it is provided with overweight warning circuit, by power supply, loudspeaker, the voice integrated package, elastic sheet metal and bonding jumper are formed, elastic sheet metal is arranged on carrying on hand of school bag, bonding jumper is provided with insulation sleeve, bonding jumper is placed in the aperture of elastic sheet metal, elastic sheet metal is provided with the contact, power supply, loudspeaker and voice integrated package are series connection, and an end of series circuit is connected with elastic sheet metal, the other end of series circuit is connected with bonding jumper, when the elastic sheet metal effect of not stressing or stressed during less than certain value, bonding jumper does not contact with the contact of elastic sheet metal, and warning circuit is off-state, when elastic sheet metal is stressed when reaching certain value, contact and bonding jumper bump and connect, and warning circuit is connected, and sounds the alarm.
Also can be connected in series signal lamp in the overweight in addition warning circuit, when the elastic sheet metal effect of not stressing or stressed during less than certain value, bonding jumper does not contact with the contact of elastic sheet metal, warning circuit is off-state, when elastic sheet metal is stressed when reaching certain value, contact and bonding jumper bump and connect, and warning circuit is connected, the luminous alarm of signal lamp.
Elastic sheet metal is arranged on carrying on hand of school bag, and when carrying hand, if when the weight of school bag surpasses the pressure that elastic sheet metal can bear, elastic sheet metal will contact with bonding jumper under the action of gravity of school bag, and closing of circuit is given the alarm; If it is when the weight of school bag does not surpass the ability to bear of elastic sheet metal, then do not send any signal, the same with common school bag.The utility model is simple in structure, and is easy to use, helps student's physical and mental health, excites student's study entertaining.
The utility model is further described below in conjunction with accompanying drawing and specific embodiment.
