Description
Technical field
The utility model relates to a kind of scissor-like jack, especially a kind of scissor-like jack for low tonnage automobile crane.
Background technology
Scissor-like jack be commonly used in low tonnage automobile crane.At present, conventional scissor-like jack is all control by the mode of rotating screw bolt the lifting supported.In use, screw rod often turns over a circle, and the distance of nut mobile pitch on screw rod, is finally converted to the distance of vertical direction movement.But because pitch is little, by the folded state of scissor-like jack to the top lifting state by weight jack-up, need rotating screw bolt multi-turn, like this carry out rising or step-down operation time, can the plenty of time be wasted.Therefore a kind of scissor-like jack that can realize extending to from folded state fast top lifting state in use is not also had in prior art.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of scissor-like jack that can realize extending to from folded state fast top lifting state in use.
The utility model solves the scissor-like jack that its technical matters adopts, comprise base, jacking block, left contiguous block, right contiguous block, left upper support bar, upper right strut bar, lower-left strut bar, bottom right strut bar and screw rod, described left upper support bar one end and left contiguous block hinged, the other end and jacking block hinged, described upper right strut bar one end and jacking block hinged, the other end and right contiguous block hinged, strut bar one end, described lower-left and base hinged, the other end and left contiguous block hinged, strut bar one end, described bottom right and base hinged, the other end is connected with right contiguous block, described left contiguous block is provided with negative thread, described right contiguous block is provided with negative thread, described screw rod is threaded with left contiguous block and right contiguous block, described left contiguous block combines with lower piece by upper piece, described upper piece on be provided with through hole and groove, described lower piece is provided with through hole and groove, described upper piece and the groove of lower piece between be provided with spring, described upper piece be connected by the attaching parts being arranged on through hole with lower piece.
Further, described attaching parts is cam lock holding mechanism.
Further, described groove is circular groove.
Further, described upper piece on be provided with boss, described lower piece is provided with the groove matched with boss, and described boss embeds in groove.
The beneficial effects of the utility model are: the scissor-like jack adopting the application, left contiguous block is separated a segment distance, can the left contiguous block of quick travel, scissor-like jack can be realized so in use to extend to top lifting state from folded state fast, or become scissor-like jack again folded state from top lifting state fast.By the upper block of attaching parts locking and lower piece, allow scissor-like jack in use left contiguous block and screw rod can realize being threaded, make the power of screw rod pass to jacking block.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the left contiguous block of the utility model;
Parts, position and numbering in figure: base 1, jacking block 2, left contiguous block 3, right contiguous block 4, left upper support bar 5, upper right strut bar 6, lower-left strut bar 7, bottom right strut bar 8, screw rod 9, attaching parts 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, scissor-like jack of the present utility model, comprise base 1, jacking block 2, left contiguous block 3, right contiguous block 4, left upper support bar 5, upper right strut bar 6, lower-left strut bar 7, bottom right strut bar 8 and screw rod 9, described left upper support bar 5 one end and left contiguous block 3 hinged, the other end and jacking block 2 hinged, described upper right strut bar 6 one end and jacking block 2 hinged, the other end and right contiguous block 4 hinged, strut bar 7 one end, described lower-left and base 1 hinged, the other end and left contiguous block 3 hinged, strut bar 8 one end, described bottom right and base 1 hinged, the other end is connected with right contiguous block 4, described left contiguous block 3 is provided with negative thread, described right contiguous block 4 is provided with negative thread, described screw rod 9 is threaded with left contiguous block 3 and right contiguous block 4, described left contiguous block 3 combines with lower piece by upper piece, described upper piece on be provided with through hole and groove, described lower piece is provided with through hole and groove, described upper piece and the groove of lower piece between be provided with spring, described upper piece be connected by the attaching parts 10 being arranged on through hole with lower piece.When needing to use the scissor-like jack of the application, first unclamping attaching parts 10, to make piece and distance that lower piece separately certain under the action of the spring, until left contiguous block 3 can first move freely screw rod 9; Then move left contiguous block 3, make left contiguous block 3 to the right contiguous block 4 draw close, left contiguous block 3 drives left upper support bar 5, upper right strut bar 6, lower-left strut bar 7, bottom right strut bar 8 in moving process, and scissor-like jack is extended; The adjusting connector 10 when scissor-like jack is stretched over top lifting state, by upper piece and lower piece of locking, then rotating screw bolt 9 can by automobile jack-up.When use need to pack up scissor-like jack time, first unclamp attaching parts 10, to make piece and distance that lower piece is separately certain under the action of the spring, until left contiguous block 3 can first move freely screw rod 9; Then move left contiguous block 3, left contiguous block 3 is moved to the direction away from right contiguous block 4, and left contiguous block 3 drives left upper support bar 5, upper right strut bar 6, lower-left strut bar 7, bottom right strut bar 8 in moving process, and scissor-like jack is folded.
Described attaching parts 10 is cam lock holding mechanism.Cam lock holding mechanism is simple to operate, can open and the upper block of locking and lower piece by fast speed, convenient by the Quick extension of scissor-like jack and folding.
Described groove is circular groove.Adopt annular groove can well limit the end of fixing spring, prevent it from occurring loosening and ejecting.
Described upper piece on be provided with boss, described lower piece is provided with the groove matched with boss, and described boss embeds in groove.Adopt the mode of boss and groove fit can realize the accurate location of block and lower piece, make both fit together fast and accurately.
