In the figure: 1. a leg body; 2. a support plate; 3. an extension plate; 4. a limiting clamping block; 5. a fixed block; 6. inserting plates; 7. a handle; 8. and a stop block.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

Examples

Referring to fig. 1-3, a novel crane supporting leg structure comprises a supporting leg main body 1 and a supporting plate 2, wherein the side wall of the lower end of the supporting plate 2 is rotatably connected with a plurality of extension plates 3 through hinges, the upper end of the supporting plate 2 is fixed with a limiting clamping block 4, the limiting clamping block 4 is slidably connected with an inserting plate 6, and a fixing block 5 matched with the inserting plate 6 is fixed on the extension plate 3; rotate extension plate 3 to the outside, then insert in extension plate 3's fixed block 5 through picture peg 6 in, because extension plate 3 is upwards rotating, and landing leg main part 1's pressure is decurrent, and stabilizes the grafting through picture peg 6 and fix, set up like this and need not additionally add the support backing plate again.

As shown in fig. 3, a stop block 8 is fixed on the insertion plate 6, the stop block 8 is arranged between the limiting clamping block 4 and the fixing block 5, and the insertion plate 6 can slide left and right in the limiting clamping block 4 without falling off by arranging the stop block 8.

As shown in fig. 2 and 3, the one end that fixed block 5 was kept away from to extension plate 3 is fixed with handle 7, and through setting up handle 7, handle 7 is located the fixed setting of the one end of keeping away from fixed block 5, has increased pivoted moment, and then reduces the strength when the pivoted, makes to rotate more laborsavingly.

As shown in figure 2, the outer wall of one side of the extension plate 3 close to the handle 7 is an inclined plane, and the outer wall of one side of the extension plate 3 is an inclined plane, so that the soil and the lower part of the inclined plane can be filled when the extension plate 3 rotates upwards, the contact area between the extension plate 3 and the soil is increased, and the support stability is improved.

As shown in fig. 2 and 3, the handle 7 is provided with anti-slip threads, so that the extension plate 3 can be rotated out more conveniently by the aid of the anti-slip threads.

The working principle is as follows: when the supporting leg main body 1 is used, when the supporting leg main body 1 is erected on the land needing to increase the supporting area, the extension plate 3 is rotated outwards and then is inserted into the fixing block 5 of the extension plate 3 through the inserting plate 6, and as the extension plate 3 rotates upwards, the pressure of the supporting leg main body 1 is downward and is stably inserted and fixed through the inserting plate 6, a supporting base plate does not need to be additionally arranged, and the supporting leg main body 1 can be supported and fixed according to different land conditions; simultaneously, the handle 7 of keeping away from the one end fixed of fixed block 5 at extension plate 3 can make things convenient for extension plate 3 to rotate, and can make extension plate 3 keep the lower extreme to peg graft with the soil when not using through handle 7 and fixed block 5, improves stability.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
