Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment:

a column jack comprises a supporting seat 1, a jack body 2 is fixedly installed at the top end of the supporting seat 1, connecting frames 3 are fixedly installed on two sides of the jack body 2, fixing frames 4 are arranged on the sides, away from each other, of the connecting frames 3, connecting rods 13 are fixedly installed on the sides, away from each other, of the fixing frames 4, fixing blocks 14 are fixedly installed at one ends, away from the fixing frames 4, of the connecting rods 13 through rotating shafts, second cavities 16 are formed in two sides of the supporting seat 1, extension springs 17 are fixedly installed inside the second cavities 16, vertical plates 18 are fixedly installed at the ends, away from each other, of the extension springs 17, connecting plates 15 are fixedly installed at the ends, away from each other, of the connecting plates 15 are fixedly connected with one sides of the fixing blocks 14, sliding grooves 20 are formed in the supporting seat 1 at the top end and the bottom end of the inner wall of each second cavity 16, and the, all slidable mounting has slider 19 in the inside of spout 20, the one end that slider 19 is close to each other all with the one end fixed connection of riser 18, because slider 19 and riser 18 fixed connection, consequently when riser 18 removes in second cavity 16, riser 18 drives slider 19 and slides in spout 20, when riser 18 outwards removes to a locating point, slider 19 is blockked spacingly by 20 inner walls of spout, at this moment, slider 19 can't continue to slide, thereby make riser 18 can't continue outwards to remove, thereby avoid riser 18 to remove floating amplitude too big, break away from with second cavity 16, thereby influence the condition that the device used, the effectual stability that has promoted this device during operation.

Slot 5 has all been seted up to one side that mount 4 is close to each other, and the equal fixed mounting of one end that link 3 kept away from each other has inserted block 6, and inserted block 6 all insert with slot 5's inside, outwards turn through holding two mounts 4, at this moment mount 4 no longer is connected with link 3 to can reduce jack body 2's cross section, thereby promoted the use scene of this device, the effectual practicality that has promoted this device.

The top end of the fixing frame 4 is provided with a through groove 11, the through grooves 11 are communicated with the slots 5, the top end of the insert block 6 is provided with a limiting groove 12, the top end of the fixing frame 4 is fixedly provided with a fixing bin 7, the bottom end of the fixing bin 7 is provided with a first cavity 8, the first cavity 8 is communicated with the through groove 11, the inside of the first cavity 8 is fixedly provided with a compression spring 9, the bottom end of the compression spring 9 is fixedly provided with an insert rod 10, the bottom end of the insert rod 10 penetrates through the through groove 11 and extends to the inside of the limiting groove 12, the top end of the fixing bin 7 is provided with a connecting groove 21, the connecting groove 21 is communicated with the first cavity 8, the inside of the connecting groove 21 is inserted with a vertical rod 22, the bottom end of the vertical rod 22 is fixedly connected with the top end of the insert rod 10, the vertical rod 22 is lifted upwards by holding the vertical rod 22, the compression spring 9 is driven by the vertical, thereby this device is installed and is dismantled, and easy operation is convenient, the effectual operating time who practices thrift the staff.

The jack body 2 is prior art, and the specific model can be selected according to actual needs, so it is not described here.

The working principle is as follows: when the staff uses this device to support 2 one side atress of object jack body, at this moment, mount 4 of jack body 2 atress side drives connecting rod 13 and fixed block 14 outwards, at this moment fixed block 14 drives connecting plate 15 and riser 18 outwards motion in second cavity 16, at this moment riser 18 drives extension spring 17 tensile deformation, at this moment extension spring 17 is owing to the elastic potential energy release that produces after the extension, the reaction force is applyed to riser 18 to the elasticity that produces, thereby make riser 18 drive connecting plate 15 inwards move, at this moment fixed block 14 drives connecting rod 13 and mount 4 inwards movement, thereby cushion the consumption with the power that jack body 2 lateral part received, thereby keep the horizontality of jack body 2 and supporting seat 1.

When some construction scenes are limited by the field, the cross section of the jack body 2 needs to be controlled, at the moment, the cross section of the jack body 2 is enlarged by the connecting rod 13, so that the device cannot be used, the vertical rod 22 is held to lift upwards, at the moment, the vertical rod 22 drives the inserted rod 10 to extrude the first cavity 8 and contract inwards, the bottom end of the inserted rod 10 is no longer limited by the limiting groove 12, at the moment, the connecting frame 3 is no longer connected with the fixing frame 4, the fixing block 14 is connected with the connecting rod 13 through the rotating shaft, at the moment, the two connecting rods 13 can be held to turn downwards, at the moment, the connecting rod 13 drives the fixing frame 4 to turn downwards, so that the cross section of the jack body 2 is reduced.

During installation, the two connecting rods 13 are held to be turned upwards, at the moment, the connecting rods 13 drive the fixing frame 4 to be close to the connecting frame 3, when the connecting rods 13 are turned to a certain position, the inserting block 6 is inserted into the slot 5, at the moment, the vertical rod 22 is held to be lifted upwards, the vertical rod 22 drives the inserting rod 10 to extrude the compression spring 9 and contract inwards, at the moment, the fixing frame 4 can be close to the connecting frame 3, when the inserting block 6 is completely inserted into the slot 5, force is stopped to be applied to the vertical rod 22, at the moment, the compression spring 9 is compressed into generated elastic force, the bottom end of the inserting rod 10 is inserted into the limiting groove 12, at the moment, the inserting rod 10 is matched with the limiting groove 12, and the fixing frame 4 is connected and fixed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
