Abstract
The invention discloses a display base capable of moving in an arc-shaped mode. The display base provided by the invention is characterized in that the upper part of the front part of the display base is open, and the open part is of a sector disk shape; the sector disk is internally provided with a sectorial tray which is corresponding to the sector disk, the bottom of the sectorial tray is supported by universal wheels, and a front arc-shaped side and a rear arc-shaped side are provided with supporting wheels which are supported by the front wall and rear wall of the sector disk; the dead rear side of the sectorial tray is fixedly provided with a shifting fork; the shifting fork is clamped at the upper end of a sliding block nut which is vertical to the bottom; a sliding block is screwed on a threaded rod which is in parallel to a bottom plate sidewise; the lower end of the sliding block nut is inserted in a horizontal groove; one end of the threaded rod is meshed with a gear and the output end gear of a speed reduction motor; when a motor is started up, the threaded rod rotates, the sliding block nut is driven to move along a sliding groove, the tray is driven by the shifting fork to move slowly and horizontally along the inside of a sector frame; when the tray moves to a side wall at one side, a stroke switch on the side wall is touched by a supporting plate, so that the motor rotates reversely, thus the supporting plate can move back and forth in sector tracks; and the tracks of the supporting plate are the tracks of any console display arranged on the tray.
Description
Technical field
The present invention relates to the computer monitor that cervical vertebra and periphery supporting tissue are shielded, specifically relate to a kind of display base can arc moving.
Background technique
Neck is the path of important nerve and blood vessel, but due to the development of modern civilization, the supporting tissue of neck is but more and more fragile, as cervical vertebra, ligament and muscle etc., and neck is often long-time deadlocked when a state, cause especially load uneven, cause the injury of neck; These injuries can cause the retrograde hyperplasia of vertebra to change, and maintain the hyperplasia plumpness of stable large ligament and the weakness of musculi colli, and the above two cause blood vessel and neural compressing, and latter increases the weight of the above two development.Thereby the head of human body should be not at a deadlock for a long time, once like this for a long time, must there is above-mentioned pathological state and occur multiple symptom, be exactly clinical alleged disease of cervical vetebra.Along with the universal people of computer are more extensive in " deadlock " of neck, people more and more recognize the urgency addressing this problem, such as notification number publication number is that CN101298897A application for a patent for invention conception is just very good, this application design drives display screen to move on arc track and drives whole arc track is moved up and down with another motor with a motor, so causes the movement up and down of computer operator's head and neck; But there is following problem in this design: 1, display device is relevant to eyesight, mobile also should, in steady state, just require supporting structure design to meet reliable mechanics principle.This patent application is usingd screwed single upright column as support, one end of one arc track is flexibly connected with support, the other end is unsettled, also specially explanation " moment that turbine and worm mechanism can also avoid arc track and flat panel display assembly weight to produce makes arc track and the tenesmus of flat panel display assembly ", and this designs exactly least steady state, not only can not avoid arc track and the tenesmus of flat panel display assembly also will certainly cause vibration in movement, therefore violate the primitive rule of product specification; 2, it is too small and will cause sighting distance and repeatedly change that the inevitable radian of track is pressed close at display screen rear portion; 3, original commercial liquid crystal screen can be pulled and realize front and rear angles variation with hand, and this display device but specially illustrates that by counterweight, being fixed in special angle has affected rational visual angle.Notification number is CN1956642A application for a patent for invention " rotatable, mobile computer monitor and television set " all " motive computer display " by name, notification number is that CN201091023Y utility model patent and CN101055772A patent application are also all made different designs on support, has in various degree huge structure complexity and the inadequate problem of stability.
Summary of the invention
In view of prior art exists above-mentioned defect, technical problem to be solved by this invention is that moving display screen is being met under medical science applied prerequisite, guarantees to divide a word with a hyphen at the end of a line reliable and stable, reduces complexity coefficient, and general all console displays.
The technical solution that the present invention addresses the above problem is:
A kind of have the display base can arc moving and comprise a low flat chassis body, it is characterized in that described chassis body upper front end is unlimited, open section is fan-shaped plate-like, before and after it, two walls and both sides are vertical with chassis, front and rear wall radian is to be the center of circle according to the same viewpoint that meets medical science sighting distance, and the radian of the arc that viewpoint to the limit mid point of covering of the fan is radius is determined.In fan-shaped disk, be provided with radian and anteroposterior diameter respective sector supporting plate, this supporting plate bottom is supported by universal wheels, and front and back arc side is provided with the front and rear wall that supporting wheel is supported on fan-shaped frame;
The positive rear side of described supporting plate sets firmly a shift fork parallel with bottom surface, this shift fork is suspended in fan-shaped disk rear side and is clamped on the cylinder of the slider nut upper end vertical with bottom surface, this slide block is spun on the screw rod parallel with base plate side direction, and the cylinder of slide block lower end inserts in the horizontal slot parallel with screw rod;
Described screw rod one end is with the driving gear engagement of the output terminal of driven gear and DC speed-reducing, when electric motor starting, bolt rotary, band movable slider moves along chute, thereby upper end of slide block cylinder promotes shift fork drive supporting plate along slowly moving horizontally in fan-shaped disk, when moving on one side sidewall, supporting plate touches the position limit switch being arranged on sidewall, motor reversal, thus realize supporting plate with the reciprocal translation of fan-shaped track; This is also the track that is placed in the console display on supporting plate.
Because liquid crystal display front and rear angles is adjustable, the damage that therefore long-term excessively leaning forward causes the moment load of neck to cause is easy to avoid, and only pulls display device angle or adjusts sitting posture; So change the stalemate key of neck in head rotation.The present invention reduces and the also application of reliable and stable power screw technology of large ratio deceleration to stand to support, drive part center of gravity, obtained the platform of stable arc translation, therefore this design not only meets medical science applied requirement, also greatly simplify the structure, the more important thing is and be applicable to all console displays.
accompanying drawing explanation
Fig. 1 is the structural representation for a kind of specific embodiment of the display base can arc moving of the present invention.
