Drawings
Fig. 1 is a schematic structural view of a preferred embodiment of a lower leg assembly for adjusting height and fixing a truss stand column of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1, an embodiment of the present invention includes: the utility model provides a lower margin subassembly for truss stand adjustment height and fixed sets up on bottom plate 2 of truss stand 1, is provided with a plurality of screw holes on bottom plate 2 of truss stand 1 and is used for the screw thread to fix lower margin subassembly.
The lower margin subassembly includes chemical bolt 3, hexagon bolt 4, hollow bolt 5, round nut 6, perpendicular subassembly and limiting plate 7, wherein, hollow bolt 5 overlaps and puts in 3 outsides of chemical bolt, make things convenient for hollow bolt 5 rotatory regulation about on chemical bolt 3, after adjusting the completion, it is spacing to screw through hexagon bolt 4 on the chemical bolt 3 and hollow bolt 5's upper portion, it is fixed to carry out holistic location, separate through flat gasket 8 between hexagon bolt 4 and the hollow bolt 5, avoid rigid connection, round nut 6 on the hollow bolt 5 external screw thread is spacing with 2 upper surfaces of bottom plate of truss stand 1 to screw, limiting plate 7 of 3 end screw thread connection of chemical bolt is spacing with 2 lower surfaces of bottom plate of truss stand 1.
In order to ensure the verticality of the chemical bolt 3 on the bottom plate 2 of the truss upright post 1, the vertical component consisting of the hollow conical ring 9 and the concave ring 10 is sleeved outside the chemical bolt 3 above the limiting plate 7 to be adjusted, wherein the upper surface of the conical ring 9 corresponds to the lower surface of the bottom plate 2 of the truss upright post 1, the convex part of the conical ring 9 corresponds to the concave surface of the concave ring 10, and the concave ring 10 is arranged in the concave clamping groove on the upper surface of the limiting plate 7, so that the construction requirement and difficulty are effectively reduced.
The utility model relates to a lower margin subassembly that is used for truss stand height-adjusting and fixed, the utility model has the advantages of simple structure, rationally, reliable, solved the inconvenient problem of the required various parallels of adjustment, gasket, simplified the adjustment step, easy operation is convenient, effectively improves the installation effectiveness.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
