Abstract
The utility model provides an infrared ray range finder, which belongs to an article for preventing a student from becoming nearsighted; the infrared ray range finder comprises a support; an infrared ray ranging alarm device is fixed on the support; a solar panel fixed on the support is in electrical connection with the infrared ray ranging alarm device; interconnecting pieces are arranged at two ends of the support. When in use, the infrared ray range finder can be worn on the head or the eyes of the student through the interconnecting pieces; when the student bends his head to an over-low position, the infrared ray ranging alarm device can give an alarm to ensure that the student forms a good habit of sitting position, and the bad sitting position of the student is corrected forcibly, thus preventing the student from myopia caused by the fact that the eyes are too close to the book, and also preventing humpback. The infrared ray range finder has the advantages of simple and reasonable structure, low manufacture cost and convenient use.
Description
Technical field
The utility model provides a kind of educational supply, especially a kind of articles for use that prevent myopia of student.
Background technology
Be the prevention myopia of student, the correct body position the when student that education department advocates learns is that eyes are 33 centimetres (i.e. 1 chis) to the distance of books.Because students ' age is little, self-control is poor, therefore, often can not reach above-mentioned requirements.Normally lie prone on the table when doing one's assignment, very lowly low, if things go on like this, easily form myopia and bow-backed.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of infrared distance measuring device is provided, and crosses the myopia that closely causes to prevent the student from books because of eyes.
The utility model is achieved in that the infrared distance measuring device, and it has support, is fixed with the infrared distance measuring warning device on the support, and solar panel and infrared distance measuring warning device fixing above the support are electrically connected, and there is link at the support two ends.
Adopt the infrared distance measuring device of said structure, can be worn on student's head or eye by link during use, low as to cross when low the student, the infrared distance measuring warning device can send chimes of doom, can make the student form good sitting posture custom, its incorrect sitting-pose is played the pressure role of correcting, prevent that the student from crossing the myopia that closely causes because of eyes from books, also can play prevention effect to hunchback.And simple and reasonable, low cost of manufacture, easy to use.
Description of drawings
Fig. 1 is the synoptic diagram of a kind of example structure of the utility model.
Fig. 2 is the synoptic diagram of another kind of example structure of the present utility model.
Fig. 3 is the synoptic diagram of the third example structure of the present utility model.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, the infrared distance measuring device of the utility model, it has support (3), is fixed with infrared distance measuring warning device (1) on the support, solar panel (2) fixing above the support is electrically connected with the infrared distance measuring warning device, and there is link (4) at the support two ends.
Described link (4) is leg of spectacles, elastic cord or hair clip.Shown in Figure 1 is that a kind of link is the viameter of leg of spectacles, leg of spectacles hangs on student's ear during use, shown in Figure 2 is that a kind of link is the viameter of elastic cord, during use, elastic cord is enclosed within student's head, shown in Figure 3 is that a kind of link is the viameter of hair clip, and during use, hair clip is clipped in student's head.
The structure of solar panel (2) and principle of work are identical with solar panel on the solar energy type electronic calculator.Obviously, also the accumulator that is electrically connected with solar panel can be arranged at infrared distance measuring warning device (1).
The structure of infrared distance measuring warning device (1) and principle of work are prior art, and the structure of disclosed this warning device has some kinds, no longer describe in detail.Link to each other the infrared distance measuring warning device that infrared emission tube, photosensitive receiving tube (infrared probe), buzzing piece link to each other with each contact of little power consumption range finder module respectively with little power consumption range finder module if any a kind of power supply; Also having a kind of model is the range finding warning integrated circuit (IC) apparatus of 4Y2 type.The utility model just is applied in above-mentioned prior art on the device of pre-myopia prevention.
Support can be the spectacle frame form.During use, the viameter of the utility model is worn on student's head or eye.Cross when near from books when the infrared probe on the infrared ray range finding warning device records student's head or eye, the buzzing piece on the infrared distance measuring warning device can send chimes of doom, reminds.
Claims (2)
1, infrared distance measuring device, it is characterized in that it has support (3), be fixed with infrared distance measuring warning device (1) on the support, solar panel (2) fixing above the support is electrically connected with the infrared distance measuring warning device, and there is link (4) at the support two ends.
2, infrared distance measuring device as claimed in claim 1 is characterized in that, described link (4) is leg of spectacles, elastic cord or hair clip.
