Abstract

A base device which can raise or lower a display panel suspended therein includes a fixing frame, a hanger for fixing the panel, two sliding rods, a connecting seat, a driving device, and a screw rod. The fixing frame includes two fixing rods spaced apart from each other and a base connected between the two fixing rods. The two sliding rods are connected to the hanger and slidably fixed to the two fixing rods. The connecting seat is fixed between the two sliding rods. The screw rod is fixed on the base. The driving device is fixed on the connecting seat and slidably connected to the screw rod. When the driving device is moved, manually or by motor, up and down along the screw rod the hanger carrying the panel is lifted up or lowered.

First claim

What is claimed is:

1. A displayer elevating device comprising:
a fixing frame comprising two fixing rods spaced apart from each other and a base connected to the two fixing rods;
a hanger for fixing a displayer;
two sliding rods connected to the hanger and slidably fixed to the two fixing rods;
a connecting seat fixed between the two sliding rods;
a screw rod fixed on the base;
a driving device fixed on the connecting seat and slidably connected to the screw rod, the driving device moves along the screw rod to drive the two sliding rods to slide along the two fixing rods;
a first shaft;
two second shafts; and
two adjusting members,
wherein the hanger is rotatably connected to the two sliding rods via the first shaft, each sliding rod defines an adjusting hole and a fixing hole, each second shaft defines a receiving hole, each second shaft is fixed to the hanger and is movably disposed in one of the adjusting holes, one end of the adjusting member passes through one of the fixing holes and is fixed in one of the receiving holes, when the two adjusting members move in an axial direction of the fixing hole, the two second shafts move within two adjusting holes to drive the hanger to rotate around the first shaft.

2. The displayer elevating device as claimed in claim 1 , wherein the driving device is a lifting hand wheel, the lifting hand wheel comprises a rotating wheel, a worm fixed to the rotating wheel and a first worm gear meshing with the worm; the first worm gear is sleeved on the screw rod and screwed with the screw rod.

3. The displayer elevating device as claimed in claim 1 , wherein base comprises at least three universal casters.

4. The displayer elevating device as claimed in claim 1 , wherein each fixing rod defines a sliding slot, two sliding slots of the two fixing rods faces each other, the two sliding rods are slidably disposed in the two sliding slots.

5. The displayer elevating device as claimed in claim 4 , wherein each sliding slots comprises a first sliding slot and a second sliding slot communicating with the first sliding slot, each sliding rod comprises a rod body and a plurality of rollers fixed to the rod body, the rod body is disposed in the first sliding slot, and the plurality of rollers disposed in the second sliding slot, a diameter of each roller is smaller than a width of the rod body.

6. The displayer elevating device as claimed in claim 5 , wherein two ribs protrude from opposite edges of each first sliding slot, each rod body defines two guiding grooves on opposite sides of the rod body, the two ribs are each slidably disposed in one guiding groove.

7. The displayer elevating device as claimed in claim 1 , wherein the adjusting member comprises a threaded rod, a smooth rod located at one end of the threaded rod, and an operating portion at the other end of the threaded rod, the fixing hole is a threaded hole, the threaded rod is movably fixed in the threaded hole, and the smooth rod is fixed in the receiving hole, a step is formed between the smooth rod and the threaded rod, the step abuts against the second shaft.

8. The displayer elevating device as claimed in claim 1 , wherein the hanger comprises a connecting member and a frame body, the first shaft is fixed to the two sliding rods, the connecting member is fixed to the frame body and is rotatably fixed to the first shaft.

9. The displayer elevating device as claimed in claim 8 , wherein the frame body comprises two fixing pieces disposed on opposite sides of the two sliding rods, the connecting member comprises two connecting pieces, each connecting piece defines a first positioning hole, each fixing piece defines a second positioning hole, the second shaft is disposed in the first positioning hole, the adjusting hole, and the second positioning hole and is fixed to the fixing piece and the connecting piece by a nut.
