Abstract
The utility model provides a roller type lifting upright column structure, and belongs to the technical field of lifting devices. The roller type lifting upright column structure comprises an inner barrel and an outer barrel; the inner barrel is arranged in the outer barrel; a plate is arranged between the inner barrel and the outer barrel; and rolling balls or rolling needles are arranged on the plate. By the rolling balls or the rolling needles, sliding friction between the inner barrel and the outer barrel can be changed into rolling friction, frictional force between the inner barrel and the outer barrel is greatly reduced, and the inner barrel and the outer barrel smoothly slide relatively.
Description
Technical field
The utility model relates to a kind of lowering or hoisting gear, especially relates to a kind of roller type lifting column structure.
Background technique
Lifting column is used for the occasion that the product height need to be regulated, such as operating table, lifting chair etc.Original lifting column mainly comprises urceolus and inner core, and described inner core is enclosed within the described urceolus, and inner core and urceolus just can slide mutually, realizes the adjusting of height.In the past directly face contact between inner core and the urceolus, during relative sliding, surface friction drag is very large, causes sliding having some setbacks, and therefore is necessary to improve.
Summary of the invention
The utility model provides a kind of roller type lifting column structure for deficiency of the prior art, and it is smooth and easy to slide between inner core and the urceolus.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: roller type lifting column structure, comprise inner core and urceolus, and described inner core is arranged in the described urceolus, be provided with plate between described inner core and the described urceolus, be provided with ball or needle roller on the described plate.Ball or needle roller can become rolling friction to the sliding friction between inner core and the urceolus, have greatly reduced the frictional force between inner core and the urceolus, so that it is more smooth and easy to slide between inner core and the urceolus.
In the technique scheme, preferably, be provided with slide rail on the described outer tube inner wall, the two ends of described slide rail are kink, described kink matches with the two ends of described plate, and described ball or needle roller two ends contact with described slide rail bottom and described inner tank theca respectively.The cooperation of slide rail and plate guarantees that plate can not rotate, and prevents that integrated circuit board is extremely between inner core and urceolus.
In the technique scheme, preferred, be provided with elastic cylindrical pin on the described inner core, described elastic cylindrical pin props up the bottom of described plate, is connected with screw on the described urceolus, and described screw passes the top that plate is stated in described outer tube side wall backstop residence.Elastic cylindrical pin and screw are used for the upper-lower position of limiting plate, prevent that plate from slip up and down occuring.
In the technique scheme, preferably, also comprise jacking block, regulator plate and adjusting bolt, be provided with through hole on the described urceolus, described jacking block is positioned at described through hole, and described regulator plate is fixed on the described urceolus, and described adjusting bolt is connected on the described regulator plate, described jacking block one end face is withstood in the end of described adjusting bolt, and described slide rail is withstood in described jacking block other end.By tightening adjusting bolt, jacking block is pushed up to slide rail one side, and adjusting bolt holds out against described slide rail, so that the ball on slide rail and the plate or needle roller close contact.
The beneficial effects of the utility model are: ball or needle roller can become rolling friction to the sliding friction between inner core and the urceolus, have greatly reduced the frictional force between inner core and the urceolus, so that it is more smooth and easy to slide between inner core and the urceolus.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Referring to Fig. 1 to Fig. 3, roller type lifting column structure comprises inner core 1, urceolus 2, jacking block 6, regulator plate 7 and adjusting bolt 71, the cross section of inner core 1 and urceolus 2 all is rectangle, inner core 1 is enclosed within the urceolus 2, is provided with plate 3 between inner core 1 and the urceolus 2, is provided with needle roller 31 on the plate 3.Needle roller also can replace with ball in the present embodiment.
All be fixed with slide rail 4 on 2 four inwalls of urceolus, the two ends of slide rail 4 are kink 41, and kink 41 matches with the two ends of plate 3, and needle roller 31 two ends contact with slide rail 4 bottoms and inner core 1 outer wall respectively.
Be fixed with elastic cylindrical pin 5 on the inner core 1, elastic cylindrical pin 5 props up the bottom of plate 3, is connected with screw 21 on the urceolus 2, and screw 21 passes the top of blocking plate 3 behind urceolus 2 sidewalls.
On two adjacent side of urceolus 2 through hole 22 is arranged, jacking block 6 is positioned at through hole 22, and regulator plate 7 is fixed on the urceolus 2, and adjusting bolt 71 is connected on the regulator plate 7, and jacking block 6 one end faces are withstood in the end of adjusting bolt 71, and slide rail 4 is withstood in jacking block 6 other ends.
