Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
In a kind of lifting desk of the present invention, the structure of desk body is as depicted in figs. 1 and 2, described
Desk body includes desktop 1 and a spike 2, and described spike 2 has two, is separately mounted to described
The lower end of desktop 1 the right and left；
Described spike 2 includes mutually being socketed to form to obtain scalable set by inner tube 3 and outer tube 4
Pipe and screw lifting device；
Described screw lifting device includes screw rod 62, nut 61, fixing termination, described nut
61 are arranged on described screw rod 62, and one end of described screw rod 62 is arranged on described fixing termination
Described fixing termination includes housing the 64, first bevel gear the 66, second bevel gear 67 and
Bearing 63, described first bevel gear 66 is co-axially mounted with described screw rod 62, described second cone
Gear 67 is arranged on described housing 64 by a regulation axle 68, described first bevel gear 66
Engaging each other with described second bevel gear 67, described housing 64 is provided with bearing fixed seat, institute
Stating bearing 63 to be arranged on described bearing fixed seat, described screw rod 62 is arranged on described bearing
On 63, described regulation axle 68 is provided with regulation through hole 65.Described fixing termination and described outer tube
4 are connected, and described nut 61 is connected with said inner tube 3, or described fixing termination is with described
Inner tube 3 is connected, and described nut 61 is connected with described outer tube 4.
Concrete, one end of described screw rod 62 is provided with bearing installation position, described bearing installation position
Radius be combined with screw rod by bearing installation position less than the radius of screw rod 62, described bearing 63
Together.Described screw lifting device is arranged in described telescopic sleeve pipe, described scalable set
Pipe is provided with cooperation through hole 5, and described cooperation through hole 5 overlaps with described regulation through hole 65, institute
State housing 64, bearing 63 and screw rod 62 to be only capable of each other relatively rotating.Coordinate through hole 5
For ensureing that rocking bar 9 can pass described regulation through hole 65.
In the present invention, the gravity of whole desktop 1 is applied on screw rod 62, the most described axle
Hold 63 screw rods 62 to be supplied to power radially, also provide to screw rod 62 1 the biggest
Axial power.General is connected, bearing fixing between bearing 63 outer ring and housing 64
63 inner rings are directly fixing with screw rod 62 to be connected, and then uses a bearing being provided that axial force.
Fig. 3 is the structural representation of rocking bar in liftable desk of the present invention；Described rocking bar 9 wraps
Including stock 91 and quarter butt 92, described rocking bar 9 can prop up spike 2 also cross said two and raise
Regulation through hole 65 on nodal axisn.In conjunction with Fig. 2, described stock 91 with the cross section of quarter butt 92 is
Rectangle, the cross section of described regulation through hole 65 is rectangle.Wherein regulate through hole 65 cross section
Shape is identical with the shape of stock 91 and quarter butt 92 cross section.
As long as rocking bar 9 being inserted regulation through hole 65 during use, spiral shell can be made by shake rocking bar 9
Bar 62 rotates, thus plays and drive rising or falling of screw rod 62 top nut 61, and then band
The dynamic desk body part that be connected fixing with nut 61 rises or declines.
When removing rocking bar 9, owing to the angle of friction between nut 61 and screw rod 62 is very big,
The effect of self-locking can be played between nut 61 and screw rod 62, thus prevent desktop 1 at gravity
Effect is lower glides.Therefore the present invention can facilitate, regulation desktop 1 efficient, high-precision height,
The fixing step after regulating height in general liftable desk can also be saved.
Fig. 4 is the structural representation of tablet chair in liftable desk of the present invention；Described tablet chair includes
Seat 7 and leg 8, described leg 8 has two, is separately mounted to described seat about 7 two
The lower end on limit, described leg 8 includes described telescopic sleeve pipe and described screw lifting device.?
In the present invention, a spike 2 of desk body is essentially identical with leg 8 theory structure of tablet chair.
Fig. 5 and Fig. 6 is respectively use state diagram during desk body lifting in liftable desk of the present invention
Use state diagram when lifting with tablet chair in liftable desk of the present invention.In conjunction with Fig. 3, described length
Bar 91 can be linked together by end with described quarter butt 92, and the length of described stock 91 is with described
The width of tablet chair is corresponding, described stock 91 be connected with quarter butt 92 after length and described desk
Width is corresponding.
So when needs regulation tablet chair height, it is only necessary to stock 91 through the regulation on tablet chair
Through hole 65.When needs desk with adjustable height, then stock 91 and quarter butt 92 are connected as a single entity,
Utilize the height coordinating regulation desk body of stock 91 and quarter butt 92.In addition rocking bar 9 is divided into quarter butt
92 and stock 91 free degree of rocking bar 9 self when can also increase desk with adjustable height.Reduction adds
Required precision during work desk body, prevents from bringing owing to the regulation through hole 65 of the left and right sides highly differs
The unworkable problem of rocking bar 9.
Beneficial effects of the present invention: sound construction, can regulate height convenient, efficiently, use
Getting up time saving and energy saving, screw lifting device uses Integration Design, compact overall structure, installs
Convenient, connect ingenious between each parts.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
