Description

Technical Field

[0001] This utility model belongs to the field of stainless steel sleeve technology, specifically a stainless steel sleeve suitable for outdoor installation. Background Technology

[0002] Stainless steel conduit is a tubular component made primarily of stainless steel. It is processed using specific techniques and possesses the characteristics of stainless steel. It is used to protect internal pipes, cables, and other equipment or to meet specific engineering requirements. During construction projects, there are often a large number of heavy machinery operations, building material handling, and frequent personnel movement on site. It is necessary to install drainage pipes, fire-fighting pipes, or cables inside stainless steel conduits. With its high strength and good toughness, stainless steel conduit can withstand certain external impacts, providing a reliable protective barrier for internal pipes and cables and preventing them from cracking, short circuits, or other problems caused by mechanical damage.

[0003] Utility model patent application publication number 202320362871.2 discloses a thermostatic sleeve suitable for outdoor installation, comprising an inner stainless steel thermostatic pipe, an outer stainless steel thermostatic pipe, an electric heating tape, a polyurethane-filled foam layer, and an outermost high-density polyethylene pipe. The main pipe structure includes the inner stainless steel thermostatic pipe, the outer stainless steel thermostatic pipe, and the outermost high-density polyethylene pipe. Second connecting flanges are fixedly fitted on both ends of the outermost high-density polyethylene pipe. Several stainless steel gaskets are fixedly connected between the inner and outer stainless steel thermostatic pipes. Heating is achieved through the electric heating tape. In winter, when the ambient temperature is too low, the electric heating tape prevents the pipe from freezing when the circulating water is shut down. Furthermore, the electric heating tape can adjust the internal temperature of the thermostatic sleeve in real time, thereby ensuring that the control cables laid inside the inner stainless steel thermostatic pipe are kept at a suitable temperature.

[0004] According to the aforementioned patent, there is a stainless steel sleeve suitable for outdoor installation. However, it still has drawbacks in actual use. The most obvious drawback is that in the installation of stainless steel sleeves, flanges are usually used for fixing. However, when there are scratches, burrs or radial grooves on the sealing surface of the flange, the effective sealing width will be reduced, which will reduce the sealing performance of the sleeve. Therefore, we propose a stainless steel sleeve suitable for outdoor installation. Utility Model Content

The second protective frame 220 is provided with an installation component to facilitate the fixing of the first protective frame 200.

[0027] Please see Figure 1 and Figure 2 The connecting ring 131 is used in conjunction with the connecting groove 120, and the first threaded groove 121 matches the second threaded groove 132.

[0028] Please see Figure 3 and Figure 4The mounting assembly includes two sets of mounting plates 210 and two sets of mounting slots 221. The two sets of mounting plates 210 are fixedly connected to the lower ends of the first protective frame 200, and the two sets of mounting slots 221 are opened at the upper ends of the second protective frame 220. The mounting plates 210 are located in the inner cavity of the mounting slots 221. The second protective frame 220 is provided with positioning members to limit the mounting plates 210. By setting the mounting plates 210 in the mounting slots 221, the connection between the first protective frame 200 and the second protective frame 220 is realized.

[0029] Please see Figure 3 and Figure 4 The positioning component includes a fixed cylinder 230, which is fixedly connected to both ends of the side wall of the second protective frame 220. A positioning rod 240 is slidably connected to the inner cavity of the fixed cylinder 230. A fixing ring 241 is fixedly connected to the side wall of the positioning rod 240. A spring 242 is fixedly connected between the side wall of the fixing ring 241 and the inner side wall of the fixed cylinder 230. The side wall of the mounting plate 210 and the inner side wall of the mounting groove 221 are both provided with positioning holes that match the positioning rod 240. By the positioning rod 240 cooperating with the positioning holes, the mounting plate 210 is limited in the mounting groove 221, and the spring 242 applies an elastic force to the fixing ring 241 and the positioning rod 240.

[0030] Please see Figure 2-4 One end of the positioning rod 240 is rotatably connected to the rotating shaft 250, and the two ends of the rotating shaft 250 are rotatably connected to the rotating head 251.

At this time, the connecting ring 131 is located on the side of the first fixing plate 110 near the connecting groove 120. Then, by rotating the rotating ring 140, the rotating ring 140 drives the connecting ring 131 to rotate. The connecting ring 131 spirals in the connecting groove 120 through the second threaded groove 132 and the first threaded groove 121, and the sealing ring on the connecting ring 131 contacts the inside of the connecting groove 120. The sidewalls are sealed to achieve a sealing effect. Then, the first protective frame 200 and the second protective frame 220 are placed on the outside of the pipe body 100. At this time, the mounting plate 210 is placed in the mounting groove 221. Then, the rotating head 251 is rotated, and the rotating head 251 drives the rotating shaft 250 to rotate. At this time, the spring 242 applies elastic force to the fixing ring 241 and the positioning rod 240. The positioning rod 240 limits the mounting plate 210 in the mounting groove 221 through the positioning hole, thereby realizing the connection between the first protective frame 200 and the second protective frame 220, and thus completing the use.
