Abstract
The utility model discloses a school bag having spring balance. The utility model includes a school-bag body which is equipped with a spring balance. The spring balance includes a handle, a weighing spring and a weight displaying device. The fixed end of the weighing spring is connected with the school-bag body. The weight displaying device can be a measuring scale and a pointer. The pointer is fixed to the fixed end of the spring. One end of the measuring scale is connected with the free end of the weighing spring and the other end is connected with the handle. The utility model is provided with simple structure and convenient use. The utility model is easy to be popularized and applied. The utility model is favorable for the growing development and the physical and mental health of the lower grade students.
Description
Technical field
The utility model relates to a kind of structure of school bag.
Background technology
At present, along with the increase of students in middle and primary schools' learning burden, student's school bag of being carried on the back of going to school every day is also more and more heavier.Bear heavy school bag for a long time,, become the social concern of a generality teenager's growing and the healthy very adverse influence that caused of the students of the junior years particularly.Seek a kind of technical scheme of effective control school bag weight, just become a problem that needs to be resolved hurrily at present.
Summary of the invention
The purpose of this utility model is in order to solve the overweight problem of student's school bag, a kind of school bag that has weighing device to be provided, making student or its head of a family, teacher can know and control the weight of school bag at any time, to avoid bearing too much weight.
The utility model is achieved through the following technical solutions: a kind of school bag with spring scale is provided, comprise the school bag body, on this school bag body a spring scale is housed also, this spring scale comprises handle, weighing spring and weight display unit, and the stiff end of weighing spring is connected with the school bag body.When the user held handle and mentions school bag, the effect of school bag gravity made the movable end of spring be subjected to displacement (being that spring is elongated), and its displacement is directly proportional with the weight of school bag; This displacement is showed by the weight display unit, thereby provides measurement result intuitively.
Described weight display unit can be rule and pointer, and this pointer is fixed with respect to the stiff end of spring, and an end of this rule is connected with the movable end of weighing spring, and the other end is connected with handle.When holding handle and mention school bag, thereby scale is subjected to displacement and makes pointer provide corresponding indication, promptly expresses the weight of school bag.
The utility model is simple in structure, easy to use, is easy to apply, and helps growing and physical and mental health of the students of the junior years.
Description of drawings
Fig. 1 is the structural representation of band spring scale school bag of the present utility model;
Fig. 2 is the structural representation of spring scale part.
The specific embodiment
Below in conjunction with accompanying drawing this practicality is described in further detail.
As shown in the figure, band spring scale school bag of the present utility model mainly is made of school bag body 1 and the spring scale 2 that is contained on this school bag body 1, this spring scale then comprises handle 3, weighing spring 4, rule 5, pointer 6, wherein the stiff end of weighing spring 4 (i.e. lower end among the figure) is fixed on the school bag body 1 by standing part 7, its movable end (i.e. upper end among the figure) then links to each other with an end of rule 5, and the other end of rule 5 links to each other with handle 3, and handle 3 is exposed at the school bag outside.When the user holds handle 3 and school bag is mentioned, the movable end of spring 4 is subjected to displacement with respect to its stiff end under the gravity effect of school bag, and pointer 6 maintains static with respect to the stiff end of spring, thereby rule 5 is subjected to displacement with respect to pointer 6, thereby expresses the weight of school bag.
The installation position of this spring scale is not unique, can be arranged on front, the back side or the side of school bag body as required.
