Abstract
The utility model discloses a mechanism for lifting desks and chairs. The mechanism comprises a worm wheel and a worm matched with each other, a fixed worm wheel, and a shell opposite to the worm, wherein the worm is connected with a rotary wheel; a lifting screw is connected with the worm gear; and an end cover arranged on a hollow lifting leg is matched with the lifting screw by threads. The worm gear and the worm matched with each other are respectively connected with the lifting screw and the rotary wheel; the lifting screw is provided with the thread-matched hollow lifting leg; and the lifting screw is driven by the rotary wheel to rotate and drive the lifting leg to lift. The mechanism disclosed by the utility model has the advantages that a handle is rotated to drive the screw to rotate so as to lift up and down. The mechanism is simple, easy to lift, unlikely to break and convenient to operate; and the mechanism is widely applicable to lifting office desks, lifting computer desk, lifting the desks and the chairs and lifting experiment tables.
Description
Technical field
The utility model relates to field of furniture, is particularly useful for the mechanism of tables and chairs lifting.
Background technology
The mechanism that is used at present the tables and chairs lifting exists the elevating mechanism complex structure, and unfailing performance is not high, and elevating mechanism adapts to poor compatibility, the defective such as is difficult to switch between multiple up-down desk and chair.In the lift adjustment process, the elevating mechanism heave amplitude is large, is difficult to smooth and steady operating and controlling and is adjusted to the appropriate location.And heavy tables and chairs plate face also causes the lift adjustment difficulty.
Summary of the invention
The problem that the utility model in use exists for solving prior art, provide a kind of for tables and chairs lifting convenient operation use, compatible good elevating mechanism.
The technical scheme that the utility model solves existing issue is: a kind of mechanism for the tables and chairs lifting, as improvement, comprise a worm gear that cooperatively interacts, worm screw, the fixing housing of worm gear, worm screw relative position, described worm screw is connected with runner, be connected with lifting screw on the worm gear, set end cap and lifting screw threaded engagement on the lifting leg of a described hollow.
As further improvement, be positioned at worm screw on the described housing and the runner junction is provided with through hole, dismountable being connected on the worm screw of described runner.
As further improvement, described runner comprises linking arm, handle, is removably connected to the rotating shaft on the worm screw, described rotating shaft connecting worm and linking arm one end, and described and handle shaft parallel is connected in the other end of linking arm.
The utility model compared with prior art, the worm and gear that matches connects respectively lifting screw and runner, lifting screw is provided with the lifting leg of the hollow of threaded engagement, driving lifting screw by rotating wheel rotates and lifting leg generation lifting, its beneficial effect is, drive bolt rotary by swinging handle and produce oscilaltion, the lifting of the utility model structure lightly, simply, not fragile, convenient operation, can be widely used in compatible lifting desk, liftable computer desk, lifting desk chair, lifting laboratory table etc.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the implementation case comprises a worm gear that cooperatively interacts, worm screw, the fixing housing 1 of worm gear, worm screw relative position, and worm screw is connected with runner 2, be connected with set end cap 41 and lifting screw 3 threaded engagement on the lifting leg 4 of lifting screw 3, one hollows on the worm gear.Rotating wheel 2, runner 2 drives worm screw and drives the worm gear rotation, cooperates with the end cap of lifting leg 4 by lifting screw 3 rotations to produce lifting.Table can be connected and fixed on the lifting leg 4 arbitrarily, and housing 1 is as feet or be connected on the feet lifting structure of formation tables and chairs.
For the ease of attractive in appearance, be positioned at worm screw on the housing 1 and the runner junction is provided with through hole 11, runner 2 dismountable being connected on the worm screw.
In the implementation case, runner 2 comprises linking arm 22, handle 23, is removably connected to the rotating shaft 21 on the worm screw, rotating shaft 21 connecting worms and linking arm 22 1 ends, and the handle 23 parallel with rotating shaft 21 is connected in the other end of linking arm 22.
