The utility model is characterized in that two front driven wheels and two rear driving assemblies are arranged on the lower part of a pedestal; a stanchion is arranged on the centre at the upper part of the pedestal, a lifting mechanism composed of a lifting cylinder and a guide screw is arranged in the stanchion; a rotary shaft falls into and can rotate in the upper part of the lifting cylinder, a driven gear is fixed on the upper part of the rotary shaft and is driven by a driving gear, and the transmission ratio is between 7 and 10; a platform is fixed on the upper part of the rotary shaft, two lower hinge blocks are respectively fixed on the two sides of the front part of the upper part of the rotary shaft and are hinged with upper hinge blocks through shafts, the upper hinge blocks are fixed on the lower part of the platform, another guide screw lifting mechanism is also arranged between the table-board and the platform and is positioned in the middle of the rear part. The utility model can realize the adjustment of the fore-and-aft position, the height, the left-and-right orientation, and the elevation/depression of the television. The utility model is used for supporting the household televisions.

Description

The adjustable TV set rack in orientation

Technical field

The utility model is that telecontrol engineering and machine walking technology are applied in the existing TV set rack, make TV set rack have position regulating function, function of regulating height thereof, about adjust function towards adjusting function and pitching.Can be as required, by remote controller moderately adjust the position of TV set rack, highly, about towards and pitching, thereby make existing TV set rack possess the function that makes the television set orientation adjustable.Belong to daily life field.

Background technology

Along with the progress and the development of society, people are more and more by the information that TV obtains, and people are more and more stronger to the dependence of television set, see that the time of TV is also more and more longer.Along with the raising of people's living standard, people are also more and more higher to the requirement of comfortableness in addition.Because people see that the position of TV usually is not unique, see that the direction of TV and angle neither be unique, this just wish the position of television set, highly, about towards doing suitable adjustment according to people's different requirements with luffing angle.At present, it is fixed that existing TV set rack all belongs to, and people often see that according to it position of TV and direction place television set in advance.Because distance, highly, towards with aspect such as luffing angle, make the beholder be easy to generate sense of fatigue, and the television image effect of being seen often is not the best, if things go on like this also make the beholder produce some diseases easily.

Summary of the invention

In order to make TV set rack have the function of adjusting the television set orientation, the utility model provides a kind of orientation adjustable TV set rack.

The utility model is achieved in that sees Fig. 1, shown in Figure 2, and two front driven wheels 2, two rear drive assemblies 3 are installed below base 1; Column 4 is installed in the center on base 1, and the elevating mechanism of being made up of lifting tube 5, leading screw 6 is installed in column 4; Rotating shaft 7 falls in the top of lifting tube 5, can rotate therein, is fixed with driven gear 8 on the top of rotating shaft 7, is driven by driving gear 9, and gearratio is between 7～10; Platform 10 is fixed on the top of rotating shaft 7, front part sides respectively is fixed with a following hinged block 11 in the above, and is hinged with last hinged block 13 by axle 12, last hinged block 13 be fixed on table top 14 below, also have another one screw-threaded shaft elevator structure 15 between table top 14 and the platform 10, be positioned in the middle of the rear portion; Preceding and the back that above-mentioned explanation is used by the television screen of putting on the TV set rack towards determining, before screen is oriented, after rightabout is.

Its effect of technique scheme is that television set is placed on the table top 14, is supported by two front driven wheels 2, two rear drive sprockets 3 together with the adjustable TV set rack integral body in orientation, by the driven in synchronism of two rear drives 3, adjusts the front and back position of TV set rack.Leading screw 6 rotates, and drives lifting tube 5 and rises or descend, and has realized the adjustment on the height.Driving gear 9 drives driven gears 8 and reverses, thus about having realized towards adjustment.When 15 work of screw-threaded shaft elevator structure, cooperate with the articulated mounting of forming by following hinged block 11, axle 12, last hinged block 13, realized facing upward the adjustment of bowing.Round Realization front and back position, highly, about towards and the adjustment of pitch angle degree, overcome the deficiency of existing TV set rack, realized goal of the invention.

Description of drawings

Fig. 1 is that orientation adjustable TV set rack broken section agent structure master looks schematic diagram, and this figure is simultaneously as Figure of abstract.Fig. 2 is that schematic diagram is looked on an adjustable TV set rack broken section agent structure left side, orientation.Fig. 3 is the adjustable TV set rack rear drive in an orientation assembly structure schematic diagram.Fig. 4 is that the adjustable TV set rack in orientation prevents mechanism's part cross-sectional schematic that lifting tube rotates with leading screw.

Embodiment

See Fig. 1, shown in Figure 2, two front driven wheels 2, two rear drive assemblies 3 are installed below base 1.Rear drive assembly 3 sees for details shown in Figure 3, and it is made up of wheel carrier 16, driving scroll bar 17, turbine 18 and driving wheel 19, and the wheel shaft that drives scroll bar 17 two ends and driving wheel 19 keeps by wheel carrier 16, and turbine 18 is fixed on the driving wheel 19, and the two is coaxial.Column 4 is installed in the center on base 1, and the elevating mechanism of being made up of lifting tube 5, leading screw 6 is installed in column 4, and the internal thread of the screw thread of leading screw 6 and the lifting tube that is mated 5 lower ends is a rectangular thread, and the lifting travel of lifting tube 5 is 300～400mm.Have chute 20 at lifting tube 5 outer walls and parallel axes, see shown in Figure 4ly, length is identical with the lifting travel of lifting tube 5, and screw 21 passes column 4 post jambs and probes in the chute 20, rotates with leading screw 6 to prevent lifting tube 5.Rotating shaft 7 falls in the top of lifting tube 5, can rotate therein, is fixed with driven gear 8 on the top of rotating shaft 7, is driven by driving gear 9, and gearratio is between 7～10; Platform 10 is fixed on the top of rotating shaft 7, front part sides respectively is fixed with a following hinged block 11 in the above, hinged by axle 12 and last hinged block 13, last hinged block 13 be fixed on table top 14 below, also have another one screw-threaded shaft elevator structure 15 between table top 14 and the platform 10, be positioned in the middle of the rear portion, adopt fine thread, lifting travel is in 10～40mm scope, and the adjusting range of corresponding table top 14 luffing angles is in ± 6 ° of scopes.Preceding and the back that above-mentioned explanation is used by the television screen of putting on the TV set rack towards determining, before screen is oriented, after rightabout is.Drive scroll bar 17, leading screw 6, driving gear 9, screw-threaded shaft elevator structure 15 by the slowspeed machine driving of rotating speed in 20～30rpm scope, the employing infrared remote controller is controlled the startup of motor and is stopped.
