For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See attached Figure 1-5 , a new type of galvanized steel pipe, including:

[0032] The tube body 1 has a locking ring 2 at each end; the locking ring 2 is provided with three limiting grooves 3;

[0033] The locking sleeve 4 is open at both ends and is sleeved on the tube body 1; the inner wall of the locking sleeve 4 is provided with an internal thread, and a limiting ring 5 is provided at one end of the opening to slide with the tube body 1;

[0034] There are three locking plates 6 and they correspond to the limiting grooves 3 one by one; one end of the locking plate 6 is provided with a limiting plate 7 that slides with the limiting groove 3, and the other end is provided with a threaded plate 8; the outer side of the threaded plate 8 is provided with an external thread that threads with the locking ring 2.

[0035] In this embodiment, the limit groove 3 is an arc groove, and the limit plate 7 and the threaded plate 8 are both arc plates; slots 9 are also provided on both sides of the threaded plate 8. An arc plug plate 10 is also provided between adjacent locking plates 6, and the two ends of the plug plate 10 are respectively inserted into the slots 9 at corresponding positions. The threaded plate 8 and the plug plate 10 are spliced ​​through the slots 9, which is convenient for disassembly and replacement; the threaded plates 8 on the three locking plates 6 and the three plug plates 10 can be spliced ​​to form a complete ring sleeved on the tube body 1. When the locking sleeve 4 is rotated, the three locking plates 6 can maintain a relative position, which is convenient for locking with the locking sleeve 4 threadedly.

[0036] It should be noted that the inner diameter of the limit ring 5 is smaller than the outer diameter of the locking ring 2. When the locking sleeve 4 slides on the tube body 1, it will be blocked by the locking ring 2 and cannot slide out from both ends of the tube body 1; the inner diameter of the opening at one end of the locking sleeve 4 where the limit ring 5 is not set is larger than the outer diameter of the locking ring 2. When the locking sleeve 4 is rotated to lock with the locking plate 6, the internal thread of the inner wall of the locking sleeve 4 will not contact the outer ring of the locking ring 2 to avoid wear.

[0037] In addition, a plurality of longitudinal grooves 11 are provided at intervals on the outer wall of the locking sleeve 4 to increase friction, facilitate manual twisting of the locking sleeve, and facilitate quick connection of adjacent steel pipe bodies 1, which can then be tightened using tools.

[0038] During actual use, two galvanized steel pipes are brought close to each other and butt-jointed; one end of the steel pipe body 1 is provided with a recessed installation groove, and the other end protrudes a connecting section that is butt-jointed with the installation groove. When the two pipe bodies 1 are butt-jointed with each other, the connecting section enters the installation groove; then the pipe body 1 is rotated to align the limiting grooves 3 on the locking rings 2 on different pipe bodies 1, so as to facilitate the insertion of the limiting plate 7 of the locking plate 6 into the limiting grooves 3 of the two locking rings 2 that are close to each other.

[0039] A gasket 12 is provided between adjacent tube bodies 1, and an avoidance groove 13 corresponding to the position of the limiting groove 3 is provided on the gasket 12. When the limiting plate 7 is inserted into the limiting groove 3, it passes through the avoidance groove 13 and then enters the limiting groove 3 on the locking ring 2 on the other tube body 1. The gasket 12 is made of rubber material and can achieve the effect of sealing and leakproofing.

[0040] The new galvanized steel pipe of the utility model is provided with a detachable and replaceable locking plate 6 and a locking ring. During the locking process, it is only necessary to rotate the locking sleeve 4, and there is no need to rotate the pipe body 1 to make the threaded part engage, which saves time and effort. On the other hand, after the locking plate 6 and the locking ring are provided, there is no need to open threads on the pipe body 1 for locking connection. When the locking plate 6 and the locking ring are rusted and the threads slip, it is only necessary to replace the locking plate 6 and the locking ring, and there is no need to replace the entire steel pipe body 1, which is beneficial to saving use costs and extending the practical life of the steel pipe. It is very practical and has good market application prospects.
