[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-Figure 7 A corrosion-resistant and wear-resistant stainless steel pipe comprises a steel pipe body 1, a plug 10 is connected to the inner wall of one end of the steel pipe body 1, a connecting plate 2 is fixedly connected to the side of the plug 10 away from the steel pipe body 1, a shell 3 is connected to the other side of the connecting plate 2, a telescopic component is connected to the inside of the shell 3, one end of the telescopic component passes through the shell 3 and the connecting plate 2, and is connected to a locking component, the locking component is located at the other end of the steel pipe body 1 away from the telescopic component, and a movable ring 5 is connected to the end of the locking component away from the telescopic component, the movable ring 5 is sleeved and rotatably connected to the outer wall of the steel pipe body 1, a marking pen 6 is connected to the inner wall of the movable ring 5, and the front end of the marking pen 6 is against the outer wall of the steel pipe body 1.

[0025] The corrosion-resistant and wear-resistant stainless steel pipe in the utility model is similar to the existing stainless steel pipe structure, such as the wear-resistant and corrosion-resistant stainless steel seamless pipe disclosed in the patent with publication number CN215568528U. Figures 1 to 7 As shown, when the corrosion-resistant and wear-resistant stainless steel pipe in the utility model needs to be cut, it is only necessary to loosen the locking assembly, and then move the movable ring 5 along the surface of the steel pipe body 1. During the movement of the movable ring 5, the telescopic assembly will gradually retract into the interior of the shell 3, and will not occupy the external space. When the movable ring 5 moves to the appropriate position, a mark is made on the surface of the steel pipe body 1 by using the marker 6, and then the movable ring 5 is continued to slide a distance so that the movable ring 5 is misaligned with the mark just made, and then the external cutting machine is used to align the mark just made to cut, and the required length can be cut quickly and conveniently. It should be specially noted here that the plug 10 can be fixedly connected to the inner wall of the steel pipe body 1 or formed as one piece, and can also be set to be detachable, without specific limitation.

[0026] Please refer to Figure 1-Figure 4 The telescopic assembly includes a coil spring 11 and a connecting soft strip 4. The coil spring 11 is located inside the shell 3, and one end of the coil spring 11 is fixedly connected to the inner wall of the shell 3, and the other end of the coil spring 11 is fixedly connected to one end of the connecting soft strip 4. The other end of the connecting soft strip 4 penetrates the shell 3 and the connecting plate 2, and is connected to the locking assembly. A scale line 401 is opened on the outer wall of the connecting soft strip 4.

[0027] More specifically, after the production process of the steel pipe body 1, the end of the connecting soft strip 4 away from the coil spring 11 can be directly connected to the locking assembly, and the total length of the entire steel pipe body 1 can be directly confirmed. When the steel pipe body 1 needs to be cut, it is only necessary to loosen the locking assembly, and then slide the movable ring 5 along the surface of the steel pipe body 1, which can drive the marking pen 6 to move on the surface of the steel pipe body 1, and during the movement, the connecting soft strip 4 will be retracted outside the coil spring 11. When the movable ring 5 moves to the appropriate position, the appropriate length can be marked by rotating the marking pen 6 on the surface of the steel pipe body 1, and then cutting can be performed by an external cutting machine.

[0028] Please refer to Figure 1-Figure 3 and Figure 5 The locking assembly includes a ramp block 7, a threaded ring 8 and a plurality of anti-slip blocks 9, which are all sleeved on the outer wall of the steel pipe body 1, and the threaded ring 8 is sleeved and threadedly connected to the outer wall of the ramp block 7, one side of the ramp block 7 is connected to the movable ring 5, and the other side of the ramp block 7 is fixedly connected to the plurality of anti-slip blocks 9, the side of the threaded ring 8 away from the movable ring 5 is abutted against the plurality of anti-slip blocks 9, and the side of the anti-slip block 9 away from the ramp block 7 is fixedly connected to the end of the connecting soft strip 4 away from the coil spring 11.

[0029] More specifically, when the movable ring 5 needs to be loosened, it is only necessary to rotate the threaded ring 8 to move the threaded ring 8 on the surface of the ramp block 7. Since the surface of the ramp block 7 is a slope, the ramp block 7 and the internally squeezed steel pipe body 1 can be slowly loosened during the movement, and the ramp block 7, the threaded ring 8 and the movable ring 5 can be slid on the surface of the steel pipe body 1. The function of the anti-dropping block 9 is to prevent the threaded ring 8 from falling off the surface of the ramp block 7.

[0030] Please refer to Figure 5 The side of the ramp block 7 close to the movable ring 5 is provided with a rotation cavity 701, and the side of the movable ring 5 close to the ramp block 7 is fixedly connected with a swivel 12, and the outer wall of the swivel 12 is slidably connected to the inner wall of the rotation cavity 701. By providing the rotation cavity 701 and the swivel 12, not only can the connection between the ramp block 7 and the movable ring 5 be strengthened, so that the two are not easy to separate; but also when it is necessary to mark the surface of the steel pipe body 1 with a marking pen 6, the movable ring 5 can be rotated to mark a circle, which is convenient for later cutting.

[0031] Please refer to Figure 6 and Figure 7 The inner wall of the movable ring 5 is provided with a spring cavity 501, and the inner wall of the spring cavity 501 is slidably connected with a pressing plate 13, which is sleeved and fixedly connected to the outer wall of the marking pen 6. By providing the spring cavity 501 and the pressing plate 13, firstly, the marking pen 6 can be prevented from falling from the inside of the movable ring 5; secondly, the marking pen 6 can be moved up and down for a distance on the surface of the movable ring 5, thereby preventing the marking pen 6 from always contacting with the surface of the steel pipe body 1, causing serious wear and affecting subsequent marking.

[0032] Please refer to Figure 6 and Figure 7 The bottom surface of the pressing plate 13 is fixedly connected with a return spring 14, and the other end of the return spring 14 is fixedly connected with the bottom surface of the spring cavity 501, and the return spring 14 is sleeved on the outside of the marking pen 6. By providing the return spring 14, when marking is not needed, the return spring 14 can be used to push up the marking pen 6, so that the marking pen 6 can be separated from the steel pipe body 1 without contact; and when marking is required, the marking pen 6 can be pressed down.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
