Detailed Description
The present invention will be further described with reference to the following examples, which are only some, but not all, of the examples of the present invention. Based on the embodiments in the present invention, other embodiments used by those skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
The utility model provides a connecting piece between square opening steel member, includes connecting block 1, limiting plate 2 and grip block 3, the terminal surface is equipped with constant head tank 4 that matches with the 9 cross-sections of steel member about connecting block 1, is located connecting block 1 and is close to constant head tank 4 lateral wall department fixed being equipped with limiting plate 2 is located connecting block 1 and is close to constant head tank 4 inside wall department and is equipped with spout 5, be equipped with on connecting block 1 with the communicating through-hole 6 of this spout 5, it is equipped with to slide in spout 5 grip block 3, be equipped with double-screw bolt 7 in the through- hole 6, 7 one end of double-screw bolt are connected with grip block 3, and the other end closes nut 8 after stretching out through-hole 6 soon, twists and moves nut 8 back, and grip block 3 can carry out.
The positioning groove 4 is used for positioning, and the limiting plate 2 plays a role in blocking; in actual use, the end of one square steel member 9 is contacted with the positioning groove 4, and the outer wall of the steel member 9 is contacted with the limiting plate 2; then, the screw bolt 7 moves in the through hole 6 by screwing the nut 9, so that the clamping plate 3 moves in the sliding groove 5 and gradually contacts with the inner wall of the steel member 9 until the side wall of the steel member 9 is clamped and fixed; the four sides of the steel member 9 are clamped through the clamping plates 3 respectively, so that the steel member 9 is fixed.
The other steel member 9 is fixed in the same way, so that the connection of the steel member 9 can be realized; carry out the centre gripping through four faces to steel member 9, prepared to have increased lifting surface for steel member 9's connection is more fastened, in the use of reality, even there is partial nut 8 not hard up to appear, under the effect of all the other nuts 8, also can guarantee the zonulae occludens between steel member 9, is connected with traditional fastener and compares, and its security is higher.
