The first protective sleeve and the second protective sleeve are both semicircular ring structures, and both ends of the first protective sleeve are fixed with connecting plates, and both ends of the second protective sleeve are provided with connecting grooves. The utility model has a reasonable structure and a clever design. Through the cooperation between the fixing sleeve and the tightening ring, the polyurethane coated sleeve has good heat insulation performance, and it also facilitates the assembly of the fixing sleeve and the tightening ring, and is easy to promote and use.

[0031] Example:

[0032] See also Figure 1-4 , including an outer sleeve 1, characterized in that: the inner cavity of the outer sleeve 1 is slidably connected to the inner sleeve 101, the outer surface of one end of the outer sleeve 1 is fixedly connected to the mounting plate 103, the outer surfaces of one end of the outer sleeve 1 and the inner sleeve 101 are fixedly connected to the connecting flange 102, and one side of the mounting plate 103 is provided with an adjustment mechanism 3, including a rotating ring 301 rotatably connected to one side of the mounting plate 103, a fixing ring 302 is fixedly connected to one side of the mounting plate 103, a pushing rod 304 is movably connected to the inner cavity of the fixing ring 302, and an arc-shaped clamping plate 305 is fixedly connected to the lower end of the pushing rod 304, and a limiting rod 308 is inserted into the inner cavity of the mounting plate 103;

[0033] Specifically, the inner sleeve 101 moves in the inner cavity of the outer sleeve 1, and the outer surfaces of the outer sleeve 1 and the inner sleeve 101 are sprayed with a polyurethane coating 2. The inner cavity of the rotating circle 301 is provided with an arc groove 303. The upper end of the push rod 304 is semicircular, and the upper end of the push rod 304 abuts against the arc groove 303. The outer surface of the push rod 304 is sleeved with a spring 1 307, and the upper end of the spring 1 307 is fixedly connected to the fixing ring 302, and the lower end of the spring 1 307 is fixedly connected to the arc clamping plate 305. A rubber pad 306 is fixedly connected to one side of the arc clamping plate 305, and the rubber pad 306 abuts against the outer surface of the inner sleeve 101. The outer surface of the limit rod 308 is movably connected to the inner cavity of the rotating circle 301, and the outer surface of the limit rod 308 is sleeved with a spring 2 309, one end of the spring 2 309 is fixedly connected to the mounting plate 103, and the other end of the spring 2 309 is fixedly connected to the handle of the limit rod 308;

[0034] Furthermore, the inner sleeve 101 is pulled outward to move it out of the outer sleeve 1, and the use length of the sleeve is flexibly adjusted to meet different needs. Then, the rotating circle 301 is rotated to squeeze the push rod 304 and the arc clamping plate 305 through the arc groove 303 to move downward to clamp and fix the outer surface of the inner sleeve 101. The arc shape of the arc groove 303 gradually changes, and the push rod 304 that can be retracted through the arc groove 303 moves its position and pulls the spring 1 307 to extend it. The arc clamping plate 305 enhances the friction with the inner sleeve 101 through the rubber pad 306 to improve the clamping stability. At the same time, the rubber pad 306 can protect the polyurethane coating 2 on the outer surface of the inner sleeve 101 from being damaged due to excessive squeezing force.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The outer surface of the connecting flange 102 is provided with a splicing mechanism 4, including a splicing sleeve 401 sleeved on the outer surface of the connecting flange 102, an insert rod 402 is inserted into the inner cavity of the splicing sleeve 401, and one end of the insert rod 402 is fixedly connected to a moving plate 403;

[0036] Specifically, the splicing sleeve 401 is semicircular in shape, and there are two splicing sleeves 401. The two splicing sleeves 401 are spliced ​​together to form a whole circle. The outer surface of the connecting flange 102 is provided with a flange hole. The plug rod 402 moves in the flange hole. The outer surface of the plug rod 402 is provided with a spring three 404. One end of the spring three 404 is fixedly connected to the moving plate 403, and the other end of the spring three 404 is fixedly connected to the splicing sleeve 401.

[0037] Furthermore, two semicircular splicing sleeves 401 are put on the outer surface of the connecting flange 102 to form a complete encirclement, and the splicing sleeve 401 limits the connecting flange 102. At this time, the elastic force of the spring three 404 itself drives the insertion rod 402 to move inward into the flange hole on the connecting flange 102 and the hole on the splicing sleeve 401, thereby fixing and limiting the two connecting flanges 102. Conversely, pulling the movable plate 403 outward can drive the insertion rod 402 to leave, thereby removing the splicing sleeve 401, and realizing automatic resetting of the insertion rod 402 through the spring three 404.

[0038] Working principle: During the use of the device, the operator pulls the inner sleeve 101 outward according to actual use requirements to move it out of the outer sleeve 1, and flexibly adjusts the use length of the sleeve to meet different needs, and then rotates the rotating circle 301 to squeeze the push rod 304 and the arc clamping plate 305 downward through the arc groove 303 to clamp and fix the outer surface of the inner sleeve 101, and pulls the spring 1 307 to extend it. The arc clamping plate 305 enhances the friction with the inner sleeve 101 through the rubber pad 306 to improve the clamping stability. At the same time, the rubber pad 306 can protect the polyurethane coating 2 on the outer surface of the inner sleeve 101 from being damaged due to excessive squeezing force. By fixing the position of the adjusted inner sleeve 101, it is ensured that the sleeve can be flexibly adjusted for use while also ensuring stability, avoiding the sleeve The displacement causes the length to change, which affects the normal use of the pipeline. When the length of a single casing is not enough and multiple casings need to be spliced ​​together for use, the operator splices the two connecting flanges 102 together, and then puts the two semicircular splicing sleeves 401 on the outer surface of the connecting flange 102 to form a complete encirclement. At this time, the elastic force of the spring three 404 itself drives the plug rod 402 to move inward into the flange hole on the connecting flange 102 and the hole on the splicing sleeve 401, and the two connecting flanges 102 are fixed and limited, so that they can be quickly and conveniently installed together. Conversely, pulling the movable plate 403 outward can drive the plug rod 402 to leave, thereby removing the splicing sleeve 401. By quickly splicing multiple casings, the use requirements of the casing can be flexibly adjusted, thereby improving the practicality of the device.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
