As improvement, this console also can be provided with emergent manual lifting mechanism.As further improvement, this console also can be provided with balanced controls.
The utility model multimedia console, rises to display device more than the table top when needing teaching to use owing to adopt above structure; When meeting was used, display device was then below deck plate, and equipment such as sound equipment can use as usual; When not using multimedia equipment, then be placed on all devices in the console and cover panel and lock, not only antitheft but also dustproof, improve the service life of equipment greatly, this console also is provided with emergent manual lifting mechanism, when in use power failure or circuit break down suddenly, can use this mechanism that display device is put back in the switch board.This console also is provided with balanced controls, spurs big weight with regard to available little transmission ratio like this, thereby reduces power consumption (energy saving power about 1/3rd).
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is this multimedia console front view.
Fig. 2 is this multimedia console left view.
As shown in Figure 1 and Figure 2, this multimedia console comprises stand 12, platform side plate 26, deck plate 27 and power switch 2.Stand 12 is generally made by angle steel, and platform side plate 26 and deck plate 27 can be made of sheet iron or other decorative panels.Deck plate 27 can be opened, and generally can open part for 1/2nd of panel overall width, protrudes from the deck plate 27 for display device 1.Power switch 2 generally places the position of being convenient to operate, and on display device side or table top, display device 1 places on the supporting plate 5.Compared with prior art, this console has been set up elevating mechanism, and its structure is as follows: supporting plate 5 can slide up and down along vertical guide rail 24.Guide rail 24 is fixed on the interior stand 12 of console, and guide rail 24 is generally 4, is symmetrically placed in the both sides in the console.Guide rail 24 is generally made by metal material with supporting plate 5.Drive screw 4 packs in the nut 3 that matches with drive screw 4 that is fixed on supporting plate 5 centers, and the lower end of screw rod 4 is fixed on the bottom of stand 12 by bearing block 23, and the end of screw rod 4 (lower end) is provided with the drive that is connected with electric transmissio mechanism.The drive of present embodiment adopts negative pulley wheel 13, and electric transmissio mechanism then adopts following structure: motor 10 is installed in the bottom of stand 12, and drive pulley 18 is installed on the motor shaft, and negative pulley wheel 13 is connected with drive pulley 18 by belt 17.The connected mode of electric transmissio mechanism also can adopt main, driven gear connection; Main, by movable sprocket by the chain connection etc.End at supporting plate 5 is provided with switch contact 8, and being provided with in the inboard of stand 12 can be by the upper and lower stop travel switch 7,9 of contact 8 shake-up.This console also is provided with emergent manual lifting mechanism, general adopt following structure: the active conical gear 15 that the lower end (top of the below negative pulley wheel 13 of bearing block 23) at drive screw 4 is provided with passive conical gear 14, be engaged with is installed in an end of power transmission shaft 22, and the other end of power transmission shaft 22 is provided with hand crank 20.Power transmission shaft 22 is installed on two bearing blocks 16 that are fixed in stand 12 bottoms, and power transmission shaft 22 is provided with back-moving spring 21, and at ordinary times, under the active force of spring, driving gear 15 is in disengaged condition with driven gear 14.This console also is provided with balanced controls, generally can adopt following structure: balance iron 11 slides up and down along the guide rail 25 that is vertically fixed on inboard, stand 12 two ends, and general every block of balance iron 11 cooperates with two guide rails 25.Balance iron 11 is connected with supporting plate 5 through pulley 19 by steel wire rope 6, on the top stand 12 of pulley 19 in pulley spindle is installed in console.The two cover balanced controls (end one cover) of symmetry are equipped with at two ends, the left and right sides in general every console.This console is based on electric lifting mechanism, be aided with manual lifting mechanism and balanced controls, if other people only are aided with manual lifting mechanism or balanced controls, or only adopt manual lifting mechanism or only adopt balanced controls, should think equivalents of the present utility model as the console elevating mechanism.
During use, when pressing power switch 2 upwards the time, the rotation of power connection motor 10 positive directions, drive the rotation of drive screw 4 positive directions, make supporting plate 5 do motion upwards for nut 3 by the rotation transmission of drive screw 4, cut off the electricity supply by contact 8 and travel switch 7 during to top dead centre, and automatic stopping makes display device 1 in running order; When pressing power switch 2 downwards the time, 10 opposite spins of power connection motor, drive drive screw 4 opposite spins, make supporting plate 5 do downward motion for nut 3 by the rotation transmission of drive screw 4, by contact 8 and travel switch 9 contact cut power supplys, and automatic stopping makes display device 1 get back to the original place during to lower dead center.When moving up and down, balanced controls are started working, and drive steel wire rope 6 by the deadweight of balance iron 11 and spur supporting plate 5 through pulley 19 and move up and down, and spur big weight with regard to available little transmission power like this.When power failure suddenly or circuit break down in using, can use emergency hand(-)drive that display device 1 is replaced, hand handgrip 20 pressed inwards make spring 21 compression, power transmission shaft 22 is done axially-movable, make the active conical gear 15 and passive conical gear 14 closures of disengagement, shake handgrip 20 and come rotating drive shaft 22, making initiatively, conical gear 15 drives passive conical gear 14 rotations, drive screw 4 begins to do downward spinning movement, allows supporting plate 5 get back to the original place.
