Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
In a kind of lifting desk of the present invention, the structure of table body as depicted in figs. 1 and 2, and described table body comprises desktop 1 and feet 2, and described feet 2 has two, is arranged on the lower end of described desktop 1 the right and left respectively;
Described feet 2 comprises and is mutually socketed to form to obtain telescopic sleeve pipe and screw lifting device by interior pipe 3 and outer tube 4;
Described screw lifting device comprises screw rod 62, nut 61, fixing termination, and described nut 61 is arranged on described screw rod 62, and one end of described screw rod 62 is arranged on described fixing termination;
Described fixing termination comprises housing 64, first bevel gear 66, second bevel gear 67 and bearing 63, described first bevel gear 66 is coaxially installed with described screw rod 62, described second bevel gear 67 is arranged on described housing 64 by a regulating shaft 68, described first bevel gear 66 engages each other with described second bevel gear 67, described housing 64 is provided with bearing fixed seat, described bearing 63 is arranged on described bearing fixed seat, described screw rod 62 is arranged on described bearing 63, and described regulating shaft 68 is provided with and regulates through hole 65.Described fixing termination is connected with described outer tube 4, and described nut 61 is connected with described interior pipe 3, or described fixing termination is connected with described interior pipe 3, 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, and the radius of described bearing installation position is less than the radius of screw rod 62, and described bearing 63 is combined by bearing installation position and screw rod.Described screw lifting device is arranged in described telescopic sleeve pipe, and described telescopic sleeve pipe is provided with and coordinates through hole 5, and described cooperation through hole 5 overlaps with described adjustment through hole 65, and described housing 64, bearing 63 and screw rod 62 only can relatively rotate each other.Coordinate through hole 5 for ensureing that rocking bar 9 can pass described adjustment through hole 65.
In the present invention, the gravity of whole desktop 1 is applied on screw rod 62, and therefore described bearing 63 not only will be supplied to the power of screw rod 62 radial direction, also will be supplied to the power of the very large axis of screw rod 62 1.General is fixedly connected with bearing 63 outer ring with between housing 64, bearing 63 inner ring is directly fixedly connected with screw rod 62, then adopts a bearing that can provide axial force.
Fig. 3 is the structural representation of rocking bar in liftable desk of the present invention; Described rocking bar 9 comprises stock 91 and quarter butt 92, and described rocking bar 9 can simultaneously through the adjustment through hole 65 on regulating shaft on described two feets 2.Composition graphs 2, described stock 91 is rectangle with the cross section of quarter butt 92, and the cross section of described adjustment through hole 65 is rectangle.Wherein regulate the shape of through hole 65 cross section identical with the shape of quarter butt 92 cross section with stock 91.
Regulate through hole 65 as long as rocking bar 9 is inserted during use, screw rod 62 can be made to rotate by shake rocking bar 9, thus play the rising or decline that drive screw rod 62 top nut 61, and then drive the table body be fixedly connected with nut 61 to divide to rise or decline.
When removing rocking bar 9, because the angle of friction between nut 61 and screw rod 62 is very large, the effect of self-locking can be played between nut 61 and screw rod 62, thus prevent desktop 1 from gliding under gravity.Therefore the present invention can facilitate, efficient, high-precision adjustment desktop 1 height, the fixing step after regulating height can also be saved in general liftable desk.
Fig. 4 is the structural representation of tablet chair in liftable desk of the present invention; Described tablet chair comprises seat 7 and leg 8, and described leg 8 has two, and be arranged on the lower end of described seat 7 the right and left respectively, described leg 8 comprises described telescopic sleeve pipe and described screw lifting device.The feet 2 of table body is substantially identical with leg 8 theory structure of tablet chair in the present invention.
Using state figure in using state figure when Fig. 5 and Fig. 6 is respectively the lifting of table body in liftable desk of the present invention and liftable desk of the present invention during tablet chair lifting.Composition graphs 3, described stock 91 and described quarter butt 92 link together by end, and the length of described stock 91 is corresponding with the width of described tablet chair, the length after described stock 91 connects with quarter butt 92 and the width of described desk corresponding.
Like this when needs regulate tablet chair height, only need stock 91 through the adjustment through hole 65 on tablet chair.When needs desk with adjustable height, then stock 91 and quarter butt 92 are connected as a single entity, utilize the height of the cooperation desk with adjustable body of stock 91 and quarter butt 92.The free degree of rocking bar 9 self when being divided into quarter butt 92 and stock 91 can also increase desk with adjustable height rocking bar 9 in addition.Reduce required precision during processing table body, the unworkable problem of rocking bar 9 preventing from the adjustment through hole 65 due to the left and right sides from highly differing bringing.
Beneficial effect of the present invention: sound construction, can regulate height convenient, efficiently, it is time saving and energy saving to use, and screw lifting device adopts Integration Design, and compact overall structure is easy for installation, connects ingenious between each parts.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
