Abstract
The utility model relates to a spiral expanding support pillar, which comprises a sleeve, wherein the upper end of the sleeve is provided with a nut base; a nut is fixed in the nut base; an upper screw rod is arranged at the upper part of the sleeve; the upper screw rod is connected with the nut; the upper end of the upper screw rod is connected with a top plate; the lower part of the sleeve is provided with a lower screw rod; the lower end of the lower screw rod is connected with a base; the screw thread of the upper screw rod is opposite to the screw thread of the lower screw rod; fixed frames are fixedly connected at the two sides of the outer wall of the sleeve; and handles are movably connected on the fixed frames. When the spiral expanding support pillar is used, the handles are rotated to drive the sleeve to rotate, so that the upper screw rod and the lower screw rod extend or shrink simultaneously to the opposite directions, thereby being convenient and fast to jack up and put down heavy objects; and the spiral expanding support pillar can also be used as a common support pillar. After being used, the rotary handles can be uplifted; therefore, the rotary handles do not occupy area. In addition, the spiral expanding support pillar has simple structure and convenient use, can effectively jack up and support the heavy objects, and can also be used in construction industry.
Description
Technical field
The utility model relates to a kind of utensil that is used for jack-up, supports weight, relates in particular to the flexible fore-set of a kind of spiral.
Background technology
Common jack-up in the daily life, support weight hydraulic jack etc. arranged, but their complex structures, cost height.
Summary of the invention
The purpose of this utility model provides the flexible fore-set of a kind of spiral simple in structure, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of spiral fore-set that stretches, comprising: sleeve is characterized in that: the upper end of sleeve is provided with nut seat, and the nut seat internal fixation has nut, and the top of sleeve is equipped with leading screw, and last leading screw is connected with nut; The upper end of last leading screw is connected with top board; The bottom of sleeve is equipped with down leading screw, and the lower end of following leading screw is connected with base; The screw thread of the screw thread of last leading screw and following leading screw is opposite.The both sides of the outer wall of sleeve are fixedly connected with fixed mount, are connected with handle on the fixed mount.
When the utility model used, turning handle can drive sleeve and rotate, and leading screw and following leading screw are stretched out or indentation simultaneously in the opposite direction, so easily and quickly jack-up with put down weight, the utility model also can be used as the fore-set use.Turning handle in the utility model can upwards lift placement, the not side of occupation of land after using.The utility model is simple in structure, easy to use, and jack-up and support weight also can be used for construction trade effectively.
