Embodiment 1

[0037] A kind of anti-shear protective sleeve of the connecting part of steel-plastic conversion pipe fitting in the preferred embodiment of the present invention, such as Figure 1-4 As shown, the protective cover main body 11 is axially divided into a first protective cover 12 and a second protective cover 13, so that the first protective cover 12 and the second protective cover 13 are hollowed out semi-cylindrical, so The section of the first protective cover 12 is provided with a first installation part 121, and the first installation part 121 is provided with a plurality of first through holes 122; the section of the second protective cover 13 is provided with the same A second installation part 131 corresponding to the first installation part 121, the second installation part 131 is provided with a lock 132 corresponding to the first through hole 122, the first protective cover 12 and the second protective cover 13 buckle synthetic protective cover main body 11; the side...

Embodiment 2

[0046] Such as Figure 5-7 As shown, the difference from Embodiment 1 is that in this embodiment, a lock cylinder 123 and a lock sleeve 124 corresponding to the lock cylinder 123 are also included, and the first mounting part 121 is provided with a The second through hole corresponding to the lock post 123, the first connecting portion 1321 is provided with a third through hole corresponding to the second through hole; the lock post 123 passes through the second through hole and the second through hole. The third through hole is described; the lower end of the lock cylinder 123 is provided with a thread corresponding to the lock sleeve 124; the upper end of the lock cylinder 123 is provided with a limit block, and the lower end is provided with a thread corresponding to the lock sleeve 124, so that the lock cylinder 123 runs through the second The second through hole and the third through hole are tightened through the locking sleeve 124 , and the stability of the installation...

Embodiment 3

[0048] Such as Figure 8-9 As shown, the difference from Embodiment 1 is that in this embodiment, the two ends of the protective cover body 11 are also provided with locking strips 23 extending toward the axis, and the outer wall of the steel-plastic conversion pipe is provided with a The groove corresponding to the locking strip 23; after the groove is provided on the outer wall of the steel-plastic conversion pipe fitting, when the protective cover is installed, the alignment can be quickly performed, and after the main body of the protective cover 11 is installed, the protective cover slips Condition.

Abstract

The invention relates to the technical field of steel-plastic conversion pipe fittings, in particular to an anti-shearing protective sleeve for a connecting part of a steel-plastic conversion pipe fitting. The protective sleeve comprises a first protective sleeve and a second protective sleeve, wherein the first protective sleeve and the second protective sleeve are both in a hollow semi-cylindrical shape; a first installation part is arranged at the section of the first protective sleeve, and a plurality of first through holes are arranged in the first installation part; a second installationpart corresponding to the first installation part is arranged at the section of the second protective sleeve, a lock catch corresponding to the first through hole is arranged on the second installation part, and the first protective sleeve and the second protective sleeve are buckled to form a protective sleeve body; reinforcing ribs are arranged on the side face of the protective sleeve body, and lock belt grooves are arranged in the two ends of the protective sleeve body. By means of the simple structure, the connecting part of the steel-plastic conversion pipe fitting of a gas conveying pipeline is protected, the damage of land subsidence to the connecting part can be resisted, the damage of other external force to the connecting part is reduced, and the protective sleeve is low in manufacturing cost, rapid and convenient to install and suitable for large-scale popularization.

Description

technical field [0001] The technical field of the steel-plastic conversion pipe fittings of the present invention, in particular, relates to a shear-resistant protective sleeve for the connection part of the steel-plastic conversion pipe fittings. Background technique [0002] my country's North China, Huanghuai and other regions have been experiencing large areas of smog during winter and spring and autumn and winter, with PM2.5 concentrations reaching hundreds, which is serious air pollution. The main reason is that coal and oil are widely used in industrial production and daily life. Hundreds of thousands of chimneys and fuel vehicles release a large amount of smoke and sulfur dioxide every day. For this reason, my country began to vigorously promote the use of clean energy in 2017. Natural gas is an indispensable energy source, especially as a green and clean energy source, natural gas is widely used in various industries and fields. The preparation and transportation of...
