Abstract

The utility model discloses a scissor jack, which comprises a base, a support table, a screw rod, a first connecting block, a second connecting block, a first support rod, a second support rod, a third support rod and a fourth support rod, wherein the support rods are mutually enclosed into a diamond. The scissor jack is characterized in that a polished shaft of the screw rod penetrates through the first connecting block provided with a movable pin, the movable pin radially penetrates through the first connecting block and the polished shaft of the screw rod, a thread of the screw rod penetrates through a through hole on the second connecting block, and a driving nut is connected onto the screw rod in a threaded manner and positioned on the outside of the second connecting block. The scissor jack has the advantages that as the movable pin radially penetrates through the first connecting block and the polished shaft of the screw rod, when the scissor jack needs return, the movable pin is pulled out, the first connecting block slides along the polished shaft of the screw rod by pressing down the support table, and then the scissor jack can be rapidly returned.

Description

A kind of scissors-type jack
Technical field
The utility model relates to a kind of jack, relates in particular to a kind of scissors-type jack.
Background technology
Jack is a support expansion tool commonly used in daily life and some disaster reliefs (as traffic accident, earthquake, landslide etc.), and our common jack mainly contains hydraulic jack, scissors-type jack etc. at present.Scissors-type jack mainly is to utilize the rotating drive strut bar of screw mandrel to erect or descend to realize its support function, but the scissors-type jack of this structure resets very slow.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of scissors-type jack that can reset fast.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of scissors-type jack, comprise base, brace table, screw rod, first contiguous block, second contiguous block and surround first strut bar of a rhombus mutually, second strut bar, the 3rd strut bar and the 4th strut bar, the lower end of described first strut bar and second strut bar is coupling on described base, the upper shaft of described the 3rd strut bar and the 4th strut bar is connected on the described brace table, the lower end of the upper end of described first strut bar and described the 4th strut bar is coupling respectively on described first contiguous block, the lower end of the upper end of described second strut bar and described the 3rd strut bar is coupling respectively on described second contiguous block, the optical axis of described screw rod partly passes described first contiguous block, described first contiguous block is provided with removable pin, described removable pin radially passes the optical axis part of described first contiguous block and screw rod, described second contiguous block is provided with through hole, described screw flight partly passes the through hole on described second contiguous block, be bolted with drive nut on the described screw rod, described drive nut is positioned at the outside of described second contiguous block.
Compared with prior art, the utility model has the advantages that because the optical axis part that removable pin radially passes first contiguous block and screw rod, when needs reset, transfer to removable pin, depress brace table then and first contiguous block is partly slided along the optical axis of screw rod scissors-type jack is resetted fast.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, a kind of scissors-type jack, comprise base 1, brace table 2, screw rod 3, first contiguous block 4, second contiguous block 5 and surround first strut bar 6 of a rhombus mutually, second strut bar 7, the 3rd strut bar 8 and the 4th strut bar 9, the lower end of first strut bar 6 and second strut bar 7 is coupling on base 1, the upper shaft of the 3rd strut bar 8 and the 4th strut bar 9 is connected on the brace table 2, the lower end of the upper end of first strut bar 6 and the 4th strut bar 9 is coupling respectively on first contiguous block 4, the lower end of the upper end of second strut bar 7 and the 3rd strut bar 8 is coupling respectively on second contiguous block 5, the optical axis of screw rod 3 partly passes first contiguous block 4, first contiguous block 4 is provided with removable pin 41, removable pin 41 radially passes the optical axis part of first contiguous block 4 and screw rod 3, second contiguous block 5 is provided with through hole, the threaded portion of screw rod 3 passes the through hole on second contiguous block 5, be bolted with drive nut 31 on the screw rod 3, drive nut 31 is positioned at the outside of second contiguous block 5.
The working process of this jack is: during use, turn drive nut 31, in the process that drive nut 31 moves inward, driving second contiguous block 5 moves inward, thereby make strut bar jack-up brace table 2, when needs reset, directly transfer to removable pin 41, depress brace table 2 then and first contiguous block 4 is partly slided along the optical axis of screw rod 3 scissors-type jack is resetted fast.
