Abstract
The invention discloses a threaded protector with demounting process holes, relating to a protective cover of a steel tube head. The threaded protector comprises a steel bushing, wherein the top of the steel bushing is a circular arc top stretched outwards, a plastic lining is arranged outside the steel bushing, a contact part of the plastic lining and the circular arc top is provided with a shoulder, the shoulder is provided with symmetric demounting process holes passing through the plastic lining and the steel bushing, and a thread is arranged outside the plastic lining. The invention has the advantage that: steel bars only need to be inserted into the demounting process holes and rotate in the certain direction after the demounting process holes are provided, thus the threaded protector can be demounted very conveniently and easily.
Description
Technical field
The present invention relates to a kind of protection external member of steel pipe tube head.
Background technology
Steel pipe very easily causes damage to pipe end in transportation, for tube head is protected, generally at pipe end suit pipe cap, also is protector.Because it is very tight that protector combines with steel pipe, the protector after feasible the installation is not easy when removing very much again.
Summary of the invention
The invention provides a kind of screw thread protection device that has the dismounting process hole, it can be easy to realize the dismounting of protector.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of screw thread protection device that has the dismounting process hole; Comprise steel bushing; The steel bushing top is the dome that outwards stretches, and steel bushing is provided with plastic inner lining outward, and plastic inner lining and dome contact part are provided with shoulder; It is characterized in that: said shoulder position is provided with the dismounting process hole of symmetry, and connects plastic inner lining and steel bushing.
The above plastic inner lining is provided with screw thread outward.
The invention has the beneficial effects as follows, be provided with the dismounting process hole after, only need steel bar is inserted the dismounting process hole, press the certain orientation rotation, can realize the dismounting of protector, very convenient easy.
