Description

The plane body height adjuster

Technical field

The utility model relates to a kind of height adjuster, particularly a kind of plane body height adjuster.

Background technique

Progress along with science and technology, people are also more and more fine and closely woven for the division of labor of various work, no matter and the requirement on precision or the quality is also strict day by day, therefore, the instrument of its operating environment and operation also needs to promote thereupon, otherwise be difficult to satisfy harsh day by day quality, the requirement of efficient, and in many relevant operating apparatus, the adjustable for height device of plane body, extensively applied to various assistant tools or working machine, on the utensil, as: table, worktable, drawing bench etc., and the structure of its Height Adjustment also influences the use of its integral body, so, how to design, produce a simple structure, easy-to-use plane body height adjuster is the problem that relevant dealer demands urgently making great efforts in fact.

Known plane body is (as table, worktable) height adjuster, as shown in Figure 6, it is to be provided with at least two sleeves 8 that are divided into both sides in the bottom surface of a plane body 7, this sleeve 8 and swivel nut one screw rod 81 make in plane body 7 bottom sides and form a support, sleeve 8 peripheries also outwards protrude out a rocking arm 82, drive the gear train that is positioned at sleeve 8 by this rocking arm 82, rotatable screw rod 81 forms flexible with respect to sleeve 8, to change the bearing height of plane body 7, and plane body 7 bottom surfaces are provided with a plurality of slide guide sleeves 9 in sleeve 8 sides in addition, can cooperate sleeve 8 to produce the effect of a balanced support; Yet, in above-mentioned this kind known structure, it is because sleeve 8 is to be the off normal design with slide guide sleeve 9, therefore, in fact when rocking arm 82 drive screws 81 extended or shrink with respect to sleeve 8, it all can produce the moment of a bending, distortion to the slide guide sleeve 9 of side, so can cause slide guide sleeve 9 expanding-contracting actions own to hinder, the whole height adjustment is had some setbacks, and this is the significant drawbacks on using.

Because known plane height degree regulating device has above-mentioned shortcoming, this creator is at the road of those shortcoming research improvement, and generation of the present utility model is arranged finally.

Summary of the invention
