Abstract
The utility model relates to a steel-plastics screw thread protection ring, which is used for protecting inner screw threads at the ends of petroleum casing pipes and various pipes. The utility model is characterized in that a steel sleeve 1 and an injection molding body 2 are injected and formed into a cylinder shape with an outer border on the upper part; the outer wall of the injection molding body 2 is provided with screw threads 4, and the upper part of the injection molding body 2 is provided with the outer border 5; the outer wall of the steel sleeve 1 is provided with four dovetail grooves 3 which are connected with the injection molding body 2 into an integral body.
Description
The utility model steel plastomer screw thread protection ring is used for the protection of the end internal thread of petroleum casing pipe and various tubing.
Similar products at home and abroad has all steel body guard ring or steel plastomer guard ring at present, and it is strong that all steel body guard ring has hardness, easily the screw thread of being protected caused damage, and the cost height, and difficulty of processing is big.Steel plastomer guard ring is the centre that metalwork is clipped in plastics, and because of the outside is a plastics, impact resistance is relatively poor, and is particularly abominable to weather conditions, and the adaptive capacity in areas such as some countries of the Middle East that the temperature difference is big and Xinjiang of China is relatively poor.
The purpose of this utility model provides a kind of steel plastomer screw thread protection ring, has adopted steel bushing to be connected with the plastics dovetail shaped, and single injection-molded is strengthened impact resistance, reduces product cost.
The utility model steel plastomer screw thread protection ring; the purpose of invention is to realize like this; the guard ring steel bushing is thick to be between 4 millimeters to 10 millimeters; and an ancient piece of jade, round, flat and with a hole in its centre is provided with dovetail groove four roads outside steel bushing; increase steel and mould adhesion; make injection molding body and steel bushing form integral body, on the injection molding body outer wall and be threaded, be consistent with various tubing end internal thread.
The utility model steel plastomer screw thread protection ring advantage is: gentle steel combination, promptly protected the screw thread of body end effectively, and have very strong impact resistance again, be applicable to various climatic environments area.
The utility model steel plastomer screw thread protection ring has following diagrammatic sketch and embodiment to provide.
Fig. 1 partly cuts open for the plan view band of the utility model steel plastomer screw thread protection ring.
Fig. 2 is the plan view of the utility model steel plastomer screw thread protection ring.
