2results about How to "Improve lateral strength" patented technology

The utility model relates to a kind of portal frame and machine tool, comprising: first crossbeam and reinforcing square tube, the cavity is formed in the first crossbeam inside, the first crossbeam extends horizontally, the reinforcing square tube extends longitudinally, the reinforcing square tube is inserted into first crossbeam longitudinally and is fixedly connected with first crossbeam.The first crossbeam of the utility model is divided into multiple segments by reinforcing square tube, the first crossbeam part of the lateral two sides of reinforcing square tube is different segment, the lateral two ends of segment are supported by support structure, and the lateral length of segment is shorter than first crossbeam, so the middle part of segment is more difficult to produce bending deformation due to external force or dead weight, the first crossbeam of multiple segments is also more difficult to produce deformation, and the movement accuracy of the drive mechanism installed on the first crossbeam is improved, and the machining accuracy of workpiece is finally improved.

The high-stability billiard lamp comprises a lamp frame and at least one lamp panel, the lamp frame comprises a plurality of lamp holders and a plurality of connecting blocks, all the lamp holders are sequentially connected end to end, any two adjacent lamp holders are connected through one connecting block, so that all the lamp holders jointly form a polygonal structure, each lamp holder comprises a plurality of folding blocks, and the folding blocks are connected through the connecting blocks. The folding blocks are sequentially connected, the folding block at the head end is connected with or separated from the folding block at the tail end, the included angle between any two adjacent folding blocks is larger than 0 degree and smaller than 180 degrees, and the lamp panel is arranged in the lamp frame. Therefore, the lamp bracket formed by the folding blocks is of a bent structure, so that the transverse strength of the formed lamp bracket can be effectively enhanced, the transverse bending resistance and the transverse torsion resistance of the lamp bracket are effectively improved, and after the lamp brackets are fixedly mounted end to end through the connecting blocks, due to the fact that the single lamp bracket is high in deformation resistance, the lamp bracket is not prone to deformation. Therefore, all parts of the polygonal structure formed by the lamp brackets are kept on the same plane, and deformation and distortion are effectively prevented.
