Abstract
The utility model provides a mandrel type casing hanger, relates to casing hanger technical field, including suspension shock absorption subassembly and butt joint positioning mechanism, the both ends side of suspension shock absorption subassembly is equipped with the sheathing part of cup joint installation, the inner side of suspension shock absorption subassembly is equipped with the butt joint positioning mechanism of penetrating cup joint, and the butt joint positioning mechanism is equipped with the sleeve part of the butt joint positioning mechanism. The butt joint positioning mechanism comprises inner end ring bases, threaded strips, third nuts, an upper grooved pipe, an upper grooved ring, a lower inserted pipe and an upper inserted ring. The inner end ring bases are arranged at the two ends of the inner side of the suspension damping assembly. According to the utility model, the annular distribution structure of the inner end ring seat is mainly utilized, so that the third nut is matched with the upper threaded strip to carry out folding operation on the upper receiving groove pipe, the upper receiving groove ring, the lower receiving insertion pipe and the upper receiving insertion ring, and a plurality of groups of grooves and bulges are folded, so that lubricating oil can be effectively sealed in equipment, and the sealing effect is good. And the lubricant can be effectively prevented from overflowing, so that the anti-wear period of equipment is prolonged while the burden of a user is reduced.
