The utility model provides an oil tank device for quenching treatment, which relates to the technical field of metal quenching and comprises an oil tank cylinder, a support frame, an electric lifting arm and a rotary stirring component. The oil groove cylinder is composed of a positioning cylinder, a movable cylinder and a spiral water cooling jacket, three-dimensional circulation flow of quenching oil is achieved through a rotary stirring assembly, and the problems that due to the fact that oil temperature distribution of a traditional quenching oil groove is not uniform, workpieces deform, oil liquid oxidation pollution is serious, and the cooling efficiency of large workpieces is low are solved. And in cooperation with a multi-stage gear transmission mechanism, the spiral stirring roller generates planetary motion in the vertical direction while horizontally rotating, and it is ensured that quenching oil forms a three-dimensional turbulent flow field. The spiral water-cooling jacket is matched with the circulating liquid pipe to realize constant-temperature control, the filter frame can quickly load and unload workpieces, and the electric lifting arm automatically finishes hoisting operation, so that the stability and the production efficiency of the quenching process are remarkably improved.

The utility model belongs to the technical field of lighting equipment, and particularly relates to a novel linear lamp installation structure which comprises an installation plate, a lamp body is arranged in the installation plate, the installation plate is movably connected with a connecting frame, the connecting frame is embedded in a ceiling, the section of the connecting frame is in a U shape, and a permanent magnet array formed by a plurality of permanent magnets is arranged on the upper end face of the inner wall of the connecting frame. Track sliding grooves are formed in the inner walls of the two sides of the connecting frame, sliding blocks are arranged at the two ends, corresponding to the track sliding grooves, of the mounting plate, clamping grooves are formed in the two inner walls of the track sliding grooves, clamping blocks are arranged at the positions, corresponding to the clamping grooves, of the two end faces of the sliding blocks, and a mounting groove is further formed in the inner wall of the connecting frame; extension plates are arranged on the two sides of the mounting plate corresponding to the elastic clamping pieces, and arc-shaped grooves are formed in the side walls of the extension plates corresponding to the elastic clamping pieces; compared with the prior art, the mounting precision is ensured, and meanwhile, bare-handed quick mounting, dismounting and maintenance are realized.
