Description

Technical Field

[0001] This utility model relates to the technical field of thread protection devices, specifically an outward-facing enveloping internal thread protector. Background Technology

[0002] In many industrial sectors such as petroleum, chemical, and machinery manufacturing, threaded connections are widely used for pipeline connections. As a critical part of pipeline connections, internal threads are easily damaged during transportation, storage, and installation. Once the threads are damaged, it may lead to loose pipeline connections, causing leaks and other safety problems, which can seriously affect the normal operation of production.

[0003] According to the authorization announcement number CN205010716U, a protector for protecting the internal thread of a pipe end and preventing pipe end deformation is disclosed. It includes an internal thread protective sleeve and a pipe end protective sleeve. The internal thread protective sleeve is fixedly connected to the pipe end protective sleeve by connecting bolts. The outer circle of the internal thread protective sleeve is tightly connected to the internal thread of the steel pipe end. The pipe end protective sleeve consists of a pipe body protective part and a pipe end protective base. The pipe body protective part is a hollow cylinder open at both ends, and the pipe end protective base is a cylinder with a diameter equal to the outer circle diameter of the pipe body protective part. The pipe end protective base is fixedly connected to one end of the pipe body protective part, and the cross-section of the fixed connection is U-shaped. The inner diameter of the pipe body protective part is larger than the outer diameter of the steel pipe end. This utility model protector greatly enhances the safety and stability of steel pipe use and transportation, effectively protects the internal thread and outer wall of the steel pipe end, has a simple structure, saves production costs, and improves work efficiency.

[0004] However, the above-mentioned devices still have shortcomings. The internal thread protector is not convenient to operate during installation and disassembly. In actual engineering applications, the protector needs to be installed and disassembled frequently. If the operation is cumbersome, it will greatly reduce work efficiency and increase labor costs. Some protectors need to be installed with the help of specific tools, and precise alignment is required during the installation process. This undoubtedly increases the difficulty of operation and the intensity of work for workers on the construction site. Utility Model Content
