Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
A kind of Portable writing lifting platform, as shown in Figure 1, described lifting platform forms primarily of upper plate 6, lower plate 7, shell fragment 5, guide groove structure 1 and spring connecting mechanism 4,
Described gathering sill 1 is symmetricly set in lower plate, and the front center of gathering sill 1 arranges spin 3,
Described shell fragment 5 is arranged between upper plate and lower plate, and in the bottom of shell fragment, centrally line arranges some spacing holes 2, and the front end of shell fragment is stretched in gathering sill and slided, and described spin falls into spacing hole 2 internal fixtion shell fragment,
Described spring connecting mechanism 4 is four groups, is symmetricly set between upper and lower plates.
Described shell fragment 5 is made up of in a superimposed manner two-layer copper sheet and one deck steel band 8, described steel band has spin groove, and described copper sheet is provided with spacing hole.
Described gathering sill 1 is made up of two panels sheet metal.
Described spring connecting mechanism 4 is turriform, and arranges in two superimposed mode.
Principle of the present utility model is:
(1) according to shell fragment flexible bending principle, adopt shell fragment-guide groove structure, be about to have certain thickness aluminium block bottom surface and mill out a step trough that multiple-layer stacked shell fragment can be inserted, left-hand thread is also fixing in lower plate, form guide groove structure, make cementing multilayer shell fragment through gathering sill.By moving freely of the slip implement device upper plate in the vertical direction of shell fragment in gathering sill.
(2) utilize the stressed rebounding characteristic of steel wire bow-shaped structural dialing spring, by the round design on shell fragment center line, realize the location of upper plate.Shell fragment direction of motion center line is processed the equidistant spacing hole of a row, be pressed in spacing hole with dialing spring by spin, when shell fragment force rectilinear motion, dialing spring and spin by jack-up, and fall into fast and close in spacing hole, and the lifting realizing upper plate is located.
(3) according to leaf spring principle, steel band bending springback and multi-layered sheet is utilized to laminate flexural glide characteristic, one deck steel band is added between two-layer copper sheet, solve the difficult problem that individual layer shell fragment working strength is low, motion is not smooth, also overcome the defect that steel band fragility is easily broken simultaneously, realize shell fragment and drive the motion homogeneous of upper plate in the vertical direction smooth and easy.
(4) utilize turriform spring self-centering characteristic and often enclose between steel wire and can not laminate characteristic, four groups of turriform spring connecting mechanisms are installed between lifting platform upper and lower plates, improve the stability of lifting platform upper plate lifting, realize upper plate and stablize floating riser.
As shown in Figure 1,1 represents gathering sill, and 2 represent spacing hole, and 3 represent spin, and 4 represent turriform spring connecting mechanism, and 5 represent shell fragment, and 6 represent upper plate, and 7 represent lower plate, and 8 represent the two-layer copper sheet and one deck steel band that superpose in shell fragment.
The maximum feature of the utility model by freely be elevated, can regulate the difference in height between lifting platform and desktop, making the utility model upper table surface and writing plane keep sustained height, and improvement is write condition and write environment.
In one embodiment, concrete structure of the present utility model is as follows:
(1) upper and lower plates size:
As shown in Figure 2, write for convenience of student, upper and lower plates size, according to the custom of the daily study of student, adopts the size identical with common books.Upper and lower plates of the present utility model adopts 2Al2 model aluminium sheet, long 230mm, wide 134mm, thick 2mm.
(2) shell fragment size:
As shown in Figure 3, the utility model upper and lower plates elevating function, needs to be realized by the elastic deformation of shell fragment.The utility model adopts 65Mn steel band to serve as shell fragment, launches long 110mm, wide 50mm, thick 0.1mm.
(3) tower spring size:
As shown in Figure 4, the utility model realizes the floating riser of upper plate by four groups of tower springs, improves stability.Tower spring adopts 70C-II model steel, steel wire diameter 0.5mm, and adopts two superimposed mode to assemble.
(4) the utility model overall dimensions:
As shown in Figure 5, the utility model overall long 230mm, wide 134mm, the maximum height 50mm that can raise, minimum altitude 15mm.
In FIG, the difference in height between books and desktop is observed.
In fig. 2, each device in this utility model upper plate, lower plate is adjusted according to the difference in height between books and desktop.
In figure 3, by the oriented sliding of shell fragment 5 in gathering sill 1, moving freely of implement device upper plate 6 in the vertical direction.By the round design on shell fragment 5 center line, realize the location of upper plate 6.Shell fragment 5 direction of motion center line is processed the equidistant spacing hole 2 of a row, be pressed in spacing hole 2 with dialing spring by spin 3, when shell fragment 5 exerts a force rectilinear motion, dialing spring and spin 3 by jack-up, and fall into fast and close in spacing hole 2, and the lifting realizing upper plate 6 is located.According to leaf spring principle, multilayer shell fragment 5 is superposed, solve individual layer shell fragment 5 and to move not smooth difficult problem, realize shell fragment 5 and drive the motion homogeneous of upper plate 6 in the vertical direction smooth and easy.
In the diagram, by between lifting platform upper and lower plates 7, lay four groups of turriform spring connecting mechanisms 4, traction table top floating equilibrium, realizes the function making table top stable elevation.
In Figure 5, according to difference in height, hand is pinned lifting platform, shell fragment 5 is moved in the direction along shell fragment 5 rectilinear motion, makes lifting platform decline desired height.Hand is pinned the other end of lifting platform, same way is before pinned and lifting platform is declined.The lifting platform regulated is flushed placement with books, makes lifting platform and books in same level, the function of lifting platform can be realized.
The beneficial effects of the utility model are, in use, student can regulate the height of Portable writing lifting platform voluntarily according to the height of books and locate, placement concordant with books, make writing plane and lifting platform upper plate in same level, hand and arm are placed on the upper plate of lifting platform and write by student, just can solve difference in height between books and desktop and, to writing the inconvenience brought, reach the function improving student's writing experience.
It should be noted that; above-mentioned specific embodiment is only exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improve or distortion all drops in protection domain of the present utility model.It will be understood by those skilled in the art that specific descriptions are above to explain the purpose of this utility model, not for limiting the utility model.Protection domain of the present utility model is by claim and equivalents thereof.
