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 bar 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 technical field of steel-plastic conversion pipe fittings of the present invention, in particular, relates to a shear-resistant protective cover for the connection part of a steel-plastic conversion pipe fitting; it includes a first protective cover and a second protective cover; both the first protective cover and the second protective cover are hollowed out Semi-cylindrical, the cross-section of the first protective cover is provided with a first mounting part, and a number of first through holes are provided on the first mounting part; the cross-section of the second protective cover is provided with a second mounting part corresponding to the first mounting part. The second mounting part is provided with a lock corresponding to the first through hole, and the first protective cover and the second protective cover are buckled to form the main body of the protective cover; the side of the main body of the protective cover is provided with reinforcing ribs, and the two ends of the main There is a locking belt groove; through a simple structure, the connection part of the steel-plastic conversion pipe fitting of the gas transmission pipeline is protected, and it can resist the damage of the connection part by ground subsidence, reduce the damage of the connection part by other external forces, and the manufacturing cost is low and the installation is easy. Fast and convenient, suitable for mass promotion.

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...
