Abstract
The utility model discloses a machinery height -regulating device, include base, lower cylinder shaped casing, go up the screw rod, cylinder shaped casing installs down the upper end of base, and be provided with the internal thread on lower cylinder shaped casing's the inner wall, upward the screw rod closes with lower cylinder shaped casing spiral shell and is connected, and be provided with compression spring down in the cylinder shaped casing, compression spring's one end top is supported on cylinder shaped casing's down bottom, other end top to the bottom of going up the screw rod, and upward install the rotation handle on the screw rod. The utility model has the advantages of simple structure and reasonable design, can realize the continuous lift of screw rod, convenient operation through rotating the handle, through installing compression spring in the cylinder shaped casing under, accomplish the back in the last screw rod process that rises, can effectively reduce the locking force of thread section department thread, prevent the thread damage.
Description
Technical field
This utility model relates to field of mechanical technique, particularly relates to a kind of machinery height-regulating device.
Background technology
Mostly the Simple lifter being arranged in ground or support platform in prior art is by upper bush, lower vertical
Post forms, and the inner chamber of described upper bush is socketed on the outer surface of lower pillar stand, has one in the side of upper bush
Row through hole, the position corresponding at lower pillar stand also has string through hole, plugs bearing pin in through hole, when needing
When regulating height, first bearing pin is taken out, then upper bush is moved at the height of correspondence, then plug
Bearing pin.Although this control method simple in construction, but can not realize continuously adjusting, it is impossible to meet to use and want
Ask.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of machinery height-regulating device.
