Abstract
The invention discloses a school bag with weight display, which comprises a school bag body. The school bag body is provided with an electronic weighting device which comprises a handle, a weighting sensor, a weighting sensor seat, a weighting sensor hanging rod, a weighting electronic chip which is electrically connected with the weighting sensor, a display device, a power supply and a power supply button, wherein the weighting sensor seat is fixedly connected with the school bag body; the weighting sensor is arranged in the weighting sensor seat; one end of the weighting sensor is fixedly connected with the weighting sensor seat, while the other free end is fixedly connected with one end of the weighting sensor hanging rod; and the handle is connected with the other end of the weighting sensor hanging rod. The school bag has the advantages of visualized display, high measuring accuracy and small occupied space.
Description
Technical field
The present invention relates to a kind of school bag, relate in particular to a kind of school bag with the weight demonstration.
Background technology
At present, the study article quantity that the student carried in last class hour rolls up, and also fills in the thing of not using the same day sometimes in school bag, so that the gross weight of school bag might surpass student's carrying capacity and influence growing up healthy and sound of student.For this reason, the patent No. is ZL200420071485.5, Granted publication number is CN2728280Y, name is called a kind of school bag with spring scale, following technical scheme is disclosed: 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, the stiff end of weighing spring is connected with the school bag body, described weight display unit can be rule and pointer, 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.Though this technical scheme has solved the problem of weighing of school bag to a certain extent, obviously has following shortcoming: certainty of measurement is relatively poor, weight shows not directly perceived; Whole spring scale places school bag, and the article that take in school bag space and easy and the school bag interfere, and influence the normal use of weighing with school bag.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art exactly, and a kind of weight intuitive display, certainty of measurement height, the space hold school bag that little band weight shows is provided.
The technical solution adopted in the present invention is: the school bag that band weight shows, comprise the school bag body, this school bag body is provided with electronic weighing device, described electronic weighing device comprises handle, LOAD CELLS, load cell block, LOAD CELLS suspension rod and the electronic chip of weighing that is electrically connected with LOAD CELLS, display, power supply and power knob, load cell block is fixedlyed connected with the school bag body, LOAD CELLS places load cell block, one end of LOAD CELLS is fixedlyed connected with load cell block, another free end is fixedlyed connected with an end of LOAD CELLS suspension rod, and handle is connected with the other end of LOAD CELLS suspension rod.
Beneficial technical effects of the present invention is: because the present invention utilizes the operation principle of electronic scale, its structure is improved and reduced volume, make electronic weighing device and place the school bag body, thereby, intuitive display, certainty of measurement height, advantage that space hold is little had.
Description of drawings
Fig. 1: be structural representation of the present invention;
Fig. 2: be operation principle block diagram of the present invention;
Fig. 3: be circuit interconnect pattern of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
As Figure 1-3, the school bag that band weight shows, comprise school bag body 1, this school bag body 1 is provided with electronic weighing device, described electronic weighing device comprises handle 4, LOAD CELLS 2, load cell block 7, LOAD CELLS suspension rod 3 and the electronic chip 9 of weighing that is electrically connected with LOAD CELLS 2, LCD display 6, power supply 8 and power knob 5, load cell block 7 is fixedlyed connected with school bag body 1, LOAD CELLS 2 places load cell block 7, one end of LOAD CELLS 2 is fixedlyed connected with load cell block 7, another free end is fixedlyed connected with an end of LOAD CELLS suspension rod 3, and handle 4 is connected with the other end of LOAD CELLS suspension rod 3.
In the present embodiment, LOAD CELLS 2 is strip, LOAD CELLS 2 has two two ends, the left and right sides that place load cell block 7 along an axis respectively, fixedly connected with LOAD CELLS suspension rod 3 with load cell block 7 by screw in the two ends of LOAD CELLS 2, LOAD CELLS suspension rod 3 is T-shaped, the two ends of handle 4 have groove, and LOAD CELLS suspension rod 3 inserts groove and is connected with handle.As further improvement, electronic weighing device also is provided with function button 10 and is electrically connected with the electronic chip 9 of weighing, and presses function button 10 convertible weight metering units (as kg, Ib) or show temperature.
During use, press power knob 5 earlier, connect power supply 8, the handle 4 of mentioning school bag again, handle 4 is by the free end deformation of LOAD CELLS suspension rod 3 pulling LOAD CELLSs 2, and LOAD CELLS 2 is sent to the signal of telecommunication gross weight that is accurately shown school bag after the electronic chip 9 of weighing is handled again by display 6.The parents of student can judge whether to surpass student's carrying capacity according to gross weight, can take out some same day no things in case of necessity with weight reduction, and the protection student grows up healthy and sound.
