Below in conjunction with drawings and Examples the utility model is further described.

Shown in Fig. 1,3, drive worm shaft 3 by motor 2 and rotate, worm shaft 3 drives worm gear 31, and worm gear 31 drives power transmission shaft 32 and rotates, because the engagement of travelling gear 5 and driven gear 6, therefore, driven shaft 33 and power transmission shaft 32 rotate synchronously.One end of chain 12 is fixed on the carriage 19, the other end is through upper right gear wheel 10 and sprocket wheel 7 engagements, be connected with an end of connector 11 through bottom right gear wheel 8 again, the other end of connector 11 is connected with an end of steel wire rope 13, and the other end of steel wire rope 13 is fixed on the carriage 19 through behind the right pulley 20 again; Upper right gear wheel 10 all is fixed on the right-hand member fixed mount 9 with bottom right gear wheel 8, and right fixed mount 9 is fixed on the main tank bracket 1, and right pulley 20 is fixed on the main tank bracket 1; Thereby constitute lifting closed-loop path, a supporting plate right side, supporting plate supporting plate lifting closed-loop path structure is identical with the right side; Supporting plate 21 lies on the carriage, and television set is placed on the supporting plate 21.

As Fig. 2, shown in Figure 3, one end of tooth bar 28 is fixed on the carriage 19, half gear 26 is fixed on the rear side of main tank bracket 1 by fixed axis 51 and support 30, one protrusion pin 29 is set on half gear 26, one end of pull bar 27 is connected with protrusion pin 29, the other end is connected with loam cake 22, the take off and landing strip carry-over bar 28 of supporting plate 21 and carriage 19 is done elevating movement, when

tooth bar

28 and 26 engagements of half gear, make 26 rotations of half gear, such half gear 26 drives pull bar 27 again and moves up and down, thereby makes the loam cake 22 of cabinet for TV do the open and close motion.

Shown in Fig. 1,2,6A, 7B, lock grate 44 is installed in the front of loam cake 22, dead bolt 47 is fixed on the upside of main tank bracket 1 by axle 46 and bearing 45, on the lock pull bar 15 projection 48 is arranged, one end of lock pull bar 15 is connected with dead bolt 47, the other end is contained in the sleeve 50, and spring 49 is arranged in the sleeve 50, and spring 49 gives the lock pull bar 15 1 power that make progress.

Shown in Fig. 1,2,4,5, door shape depression bar 17 is installed in supporting plate 21 rear sides, the middle part of door shape depression bar 17 is provided with a crosspiece 39, one end of fourth shape depression bar 16 is fixedlyed connected with an end of cantilever lever 40, cantilever lever 40 is fixed on by bearing pin 41 and bearing 42 on the rear cross beam 18 of main tank bracket 1, and brake switch 43 is installed in bottom and the fourth shape depression bar 16 and the door shape depression bar 17 corresponding positions of main tank bracket 1.

Shown in Fig. 2,3, the inside, both sides of main tank bracket 1 is installed slide rail 25 respectively, with slide rail 25 opposite positions grooved sliding pallet 52 is installed respectively on the carriage 19 of both sides, and grooved sliding pallet 52 moves up and down along slide rail 25, and supporting plate 21 is steadily moved up and down.

When motor 2 is just changeing, when supporting plate 21 is done ascending motion, open on the loam cake 22, supporting plate breaks away from projection 48, and dead bolt 47 is withdrawed from from lock grate 44 automatically, supporting plate 21 rises and drives 17 risings of door shape depression bar, the strut rail 39 of door shape depression bar 17 collides with an end of cantilever lever 40, makes the bottom compacting brake switch 43 of fourth shape depression bar 16, makes motor 2 outages, supporting plate 21 stop motions, like this television set on the supporting plate 21 just be raised to cabinet for TV above.When motor 2 counter-rotatings, when supporting plate 21 was done descending motion, crosspiece 39 broke away from cantilever lever 40, make the bottom of fourth shape depression bar 16 break away from brake switch 43, door shape depression bar 17 is along with supporting plate 21 descends, and when its bottom compacting brake switch 43, motor 2 cuts off the power supply, supporting plate 21 stop motions, television set is in the cabinet for TV, and loam cake 22 is closed, and supporting plate descends when putting in place, collision projection 48 makes the nip lock grate 44 of loam cake 22 of dead bolt 47.

The utility model circuit as shown in Figure 8, motor 1 line normal open, B ₁Closed, B ₂Disconnection, remote controller make A ₁Disconnection, A ₂Closed, motor 3 lines are connected, motor just changes, supporting plate rises, as the bottom of fourth shape depression bar 16 compacting B ₁, B ₂, make B ₁Disconnect B ₂Closure, motor 2 \ 3 lines disconnection this moment motor does not change; Remote controller makes A ₁Closure, A ₂Disconnect B ₁Still for disconnecting B ₂Closure state, motor 2 lines are connected, the motor counter-rotating, supporting plate descends; As the bottom of door shape depression bar 17 compacting B ₁, B ₂Make B ₁Closure, B ₂Disconnect, then motor 2,3 lines disconnect, and motor does not change.

This cabinet for TV also can be laid video recorder, makes video recorder automatic horizontal turnover cabinet for TV.

The utility model advantage: because the automatic open and close of cabinet for TV loam cake, so, easy to use concerning the user, simple to operate; Because automatic detent mechanism is installed, have anti-theft feature, and can effectively control the use of television set.
