Description

The TV board that height is adjustable

The utility model relates to articles for daily use, specifically, relates to the adjustable TV board of a kind of height.

Though what existing TV board had can rotate, and all has only a kind of height, sense inconvenience in the time of in use.

The TV board that provides a kind of height adjustable is provided the purpose of this utility model, and the TV board that this height is adjustable is driven by motor, when needs rise, as long as just press the height that switch can improve television set smoothly; When needs descend, as long as just press switch and can realize.

The purpose of this utility model is to realize like this, construct the adjustable TV board of a kind of height and comprise mechanical part and circuit part, mechanical part comprises base plate 19, be used to place the carriage 18 of television set, be installed in motor 1 and bearing 4 on the described base plate 19, be installed in described base plate bottom surface four universal wheel 5-8 all around, worm screw 2 with motor 1 spindle coupled, be contained in above the described bearing 4, worm gear 3 with described worm screw 2 engagements, the helical screw 9 that is connected with the center of described worm gear 3, activity external member 10 with helical screw 9 engagements, be fixedly mounted on the described base plate 19 and be in the round pillar overcoat 17 of described worm gear 3 peripheries top, the opposite side of described round pillar overcoat 17 inwalls is respectively equipped with groove 13 and 14, the lower end of described activity external member 10 is provided with flange 11 and 12, described groove 13 and 14 upper port are respectively equipped with stop fixture block 15 and 16, the upper end of described activity external member 10 is removably mounted on the bottom surface of described carriage 18, described circuit part comprises a reversing switch, also comprises the up limit switch 20 that is installed in described stop fixture block 15 bottoms and is installed in the descending limit switch 21 that described vertical tube 14 bottoms can be touched by described activity external member.

Implement the adjustable TV board of height of the present utility model, can adjust the placement height of television set easily, and simple in structure, cost is lower.

In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:

Fig. 1 is the schematic diagram of the mechanical part of the adjustable TV board of the utility model height;

Fig. 2 is the schematic diagram of the circuit part of the adjustable TV board of the utility model height.

In Fig. 2, switch is used for controlling the liter of television set height or falling, and rising stop contact is used for stopping motor operation when being raised to the rising extreme position; Decline stop contact is used for stopping motor operation when dropping to extreme position.
