Abstract
The utility model discloses a desk which comprises a desk body and a distance detector, wherein the edge of one side of a desktop is of an inwards concave arc shape. The distance detector is arranged in the middle of the arc shape, a small bulb is arranged at one corner of the desktop of the desk, and a buzzer is arranged at the other corner of the desktop. The distance detector comprises a far infrared transmitter, a far infrared receiver, a single-chip microcomputer and a power source, the far infrared receiver is connected with the single-chip microcomputer by a lead wire, the single-chip microcomputer is connected with the small bulb and the buzzer by a lead wire, a bidirectional key is arranged among the single-chip microcomputer, the small bulb and the buzzer, and the small bulb or the buzzer is controlled by gating of the key to work. The desk can sense the distance of a user away from the desk, properly gives warning, enables the user to often adjust an unscientific sitting position self in the process of use, and thus reduces occurrence rate of myopic eye and cervical spondylosis.
Description
Technical field
The utility model relates to desk, relates in particular to a kind of desk.
Background technology
Desk has a very important role in our daily life and work, places the platform of books when it can provide people to write and during reading, makes people more convenient when bending over one's desk working, do not need book is hand held in, make head with book.But, also has characteristic so easily just because of desk, make the person of bending over one's desk working under working for a long time, can be in spite of oneself near desk, destroying correct reading posture, so talk about for a long time, is that strength or backbone all can have damage for the reader, therefore, make desk have the function of correcting faulty sitting posture and just seem very necessary.At present, the desk of correcting function has appearred having on the market, such as, some desks are considered at the edge of desk one side, the chin fixture to be housed, and make the reader when bending over the desk to read, head and desktop can keep the distance that sets in advance all the time, but such desk in use can be very uncomfortable, in addition, fixture can not be adjusted according to everyone characteristics, but a kind of mode of use that can only mechanization is regulated.
The utility model content
For the problems referred to above that exist in existing mop, the utility model provides a kind of rotary mop.
The technical scheme that the utility model technical solution problem adopts is:
A kind of desk, comprise a body and range finder, wherein, the front edge place of described table body is the curved edge that concaves, central authorities at described curved edge are provided with range finder, desktop wherein be provided with miniature bulb on one jiao, described miniature bulb is connected by wire with described range finder, be provided with buzzer on another angle of desktop, described buzzer is connected by wire with described range finder.
Described desk, wherein, described range finder comprises RF transmitter, infrared receiver, single-chip microcomputer and power supply, and described infrared receiver is connected with single-chip microcomputer, and described power supply is dry cell.
Described desk, wherein, described RF transmitter is fixedly connected on a necklace.
Described desk wherein, is provided with the dibit telegraph key between described range finder and described miniature bulb and described buzzer.
Technique scheme has following advantage or beneficial effect:
the utility model is provided with position sensor at the desktop edge, position sensor comprises RF transmitter, infrared receiver and single-chip microcomputer, the time that the infrared ray that single-chip microcomputer sends by RF transmitter arrives infrared receiver calculates distance, single-chip microcomputer is connected with buzzer with miniature bulb, as the user near in the limited field of desk the time, will come reminding user by miniature bulb or buzzer, the user can adjust according to self actual conditions the sitting posture of oneself, therefore, the utility model is not to force the user to reach standardized reading posture, but make the conscious adjustment sitting posture of user by prompting, very hommization.
Description of drawings
Fig. 1 is the structural representation of the utility model desk.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as restriction of the present utility model.
As shown in Figure 1, the utility model is a kind of desk.Comprise a body and range finder.The edge of desktop one side is the arc that concaves, and is provided with range finder in arcuate center, is provided with miniature bulb 2 at desk desktop one jiao, is provided with buzzer 1 at another angle of desktop.Range finder comprises RF transmitter 3, infrared receiver 4, single-chip microcomputer and power supply, infrared receiver 4 is connected by wire with single-chip microcomputer, single-chip microcomputer is connected by wire with buzzer 1 with miniature bulb 2, be provided with two-way telegraph key between single-chip microcomputer and miniature bulb 2 and buzzer 1, by the gating of telegraph key, can control miniature bulb 2 work or buzzer 1 work.
RF transmitter 3 is arranged on a necklace, when using the utility model, necklace is worn on neck, this moment, infrared receiver 4 just can receive the infrared ray that the RF transmitter 3 on necklace is launched, by signal is transferred to single-chip microcomputer, single-chip microcomputer can receive the infrared ray time used by infrared receiver 3, thereby calculate the user apart from the distance of desk, calculate distance rear by pre-set scheme, if distance is outside safe range, single-chip microcomputer can be connected miniature bulb 2 or buzzer 1, miniature bulb 2 and buzzer 1 will give the alarm by different modes, the user controls the connection of two-way telegraph key, can select the warning mode wanted.
In sum, the utility model is a kind of desk, for the problem that exists in existing desk, desk is carried out new design, install range finder additional by the side at desk, make desk can sense the user for the distance of leaving desk, in time warn, allow the user in use can often adjust the not science sitting posture of oneself, thereby reduce the occurrence probability of suffering from myopia and cervical spondylopathy.
The above is only the utility model preferred embodiment; not thereby limit claim of the present utility model; so the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in protection domain of the present utility model.
