Abstract
A hand-crank lifting desk rack belongs to furniture field, comprising two vertical support column components to support the desk board, the support column components also comprise a hollow square-tube arranged at the bottom and a shrinking tube on top, a hollow stopcock is arranged between the hollow square-tube and the shrinking tube, the center part of the support column components is provided with a vertical thread bar; a hollow beam is arranged between two support column components, and the center position of the beam is provided with a rocker axis, the vertical thread bar and a rocking handle are respectively connected with one side of the rocker axis by a pair of occlusive bevel gears; the other side is fixed on the jacket of the other support column components. The lifting desk is of simple and convenient operation, durability, availability for children above five-year-old and adults, high security and practicability, and can be an ideal studying desk for students and adults.
Description
Technical field
The utility model belongs to field of furniture, particularly in computer desk and workbench, is used to regulate the hand-rail type lifting desk frame of desk height.
Background technology
In the adjustment action of desk height, lifting is to realize by stretching of table pin length.The desk that has only the pupil to use at present has height-adjustable function, and is to realize by more original mode.This regulative mode is child's independent operation of having no way not only, adult's gas of also requiring great effort very much that operates.The life-span of this type of desk is very short in addition.How could become child's study desk and to regulate height and durable in use easily, thereby produce the hope and the demand of further reform.
Summary of the invention
The utility model technical issues that need to address are, relatively require great effort and child is difficult to weak points such as independent operation at existing up-down mode, for overcoming these defectives, just need a kind of version of redesign, the purpose of this utility model, provide a kind of hand-rail type lifting desk frame, it belongs to split-type structural mechanical elevating frame, and it rotates rising or the reduction that drives the desk foot rest by adopting bevel gear.
The purpose of this utility model is to adopt following technical scheme to realize, a kind of hand-rail type lifting desk frame, comprise two vertical support column assemblies that are used to support desk faceplate, it is characterized in that, this support column assembly comprises a hollow square tube that is positioned at the bottom again, and superposed telescoping tube, being provided with the hollow pipe close between described hollow square tube and the telescoping tube, its centre is a vertical threaded bar; Be hollow cross between two support column assemblies, there is rocker shaft this crossbeam center, and a side of this rocker shaft links to each other with vertical threaded bar and crank handle respectively through the bevel gear of a pair of interlock; Opposite side is fixed on another support column assembly sheath.Crank handle rotates bevel gear, and another bevel gear of interlock rotates synchronously with it, thereby drives vertical threaded bar and the rotation of horizontal rocker shaft, and then promotes moving up and down of telescopic steel pipe, and realizes the automatic lifting function.
The beneficial effects of the utility model are this hand-rail type lifting desk frame, easy to operate, durable in use, suitable children and adult's use, economical and practical more than five years old.
Description of drawings
Fig. 1 is the outward appearance and the partial sectional view of lifting desk frame.
The specific embodiment
With reference to Fig. 1, the outward appearance and the partial sectional view of expression lifting desk frame.Among the figure, 1 is the square tube of support column assembly, it on it telescoping tube 2, be hollow pipe close 3 between the two, central part is a threaded bar 5, its outside is with nylon square 6, its lower end is the bevel gear 4 of two interlocks, it links to each other with crank handle 7 and horizontal rocker shaft 8, rocker shaft places hollow cross 10 through stator 9, the end is the sheath 11 that places support column assembly square tube outer, by rocking handle in left and right two ends of rocking bar power transmission shaft (an optional end) back with 360 ° clockwise or counterclockwise shake, drive the bevel gear rotation at rocker shaft two ends.The angular wheel of interlock rotates synchronously along with the rotation of bevel gear with it, rotates thereby drive the threaded bar that is welded with bevel gear, and the threaded bar that is welded with bevel gear that drives the other end by power transmission shaft is rotated; And then promote moving up and down of two telescopic steel pipes about foot rest by the nylon square that has internal thread simultaneously.Adopt spacing iron block, spacing plastics spacer to limit the up stop and the descending stop of telescopic steel pipe, thereby realize the automatic lifting function.Because rocking handle can freely be dismantled,, can change on the rocking bar power transmission shaft of another side and realize elevating function on one side fail to realize elevating function by wall or because of other reason.After realizing elevating function, rocking handle can be packed up, avoid child to bring and play.In addition, the rocking bar power transmission shaft can prevent that with its cover child is injured with sheath in the above.
Claims (2)
1. hand-rail type lifting desk frame, comprise two vertical support column assemblies that are used to support desk faceplate, it is characterized in that, this support column assembly comprises a hollow square tube that is positioned at the bottom again, and superposed telescoping tube, be provided with the hollow pipe close between described hollow square tube and the telescoping tube, its centre is a vertical threaded bar; Be hollow cross between two support column assemblies, there is rocker shaft this crossbeam center, and a side of this rocker shaft links to each other with vertical threaded bar and crank handle respectively through the bevel gear of a pair of interlock; Opposite side is fixed on another support column assembly sheath.
2. hand-rail type lifting desk frame according to claim 1 is characterized in that, described rocker shaft is that the pulley that is through in two ends, left and right sides steel pipe the inside fixes, and threaded bar is to be through that the hollow pipe close that is fixed in the steel pipe and nylon square fix and spacing.
