The protective mechanism 2 includes a fixing ring 201, a protective box 202 and a buffer plate 204. The fixing ring 201 is fixedly installed on the surface of the elbow body 1, the protective box 202 is slidably connected to the surface of the elbow body 1, and the buffer plate 204 is slidably connected to the surface of the elbow body 1.

[0031] In this embodiment, the protective mechanism 2 can be used to transport steam or hot water through the elbow body 1 so that the elbow body 1 is expanded under force. The protective box 202 can limit the elbow body 1 to prevent it from moving. At the same time, the buffer plate 204 can be deformed as the elbow body 1 expands to prevent the elbow body 1 from cracking and damage due to stress generated by thermal expansion. The connecting mechanism 3 can push the slide rod 306 to squeeze the limit block 303, so that the No. 1 spring 304 retracts and drives the limit block 303 to rise. At the same time, the No. 2 spring 308 is stretched under force. After the slide rod 306 slides to the appropriate position, the No. 1 spring 304 rebounds and drives the limit block 303 to move, so that the limit block 303 is engaged with the slide rod 306 to connect and fix the two protective boxes 202.

[0032] Reference Figures 2 to 3 In one aspect of this embodiment, a heat-insulating layer 203 is fixedly installed on the inner wall surface of the protection box 202 , and a buffer plate 204 is fixedly installed on the inner wall surface of the heat-insulating layer 203 .

[0033] In this embodiment, when the elbow body 1 transports steam or hot water and causes the elbow body 1 to expand under force, the protective box 202 can limit the elbow body 1 to prevent it from moving. At the same time, the buffer plate 204 can deform as the elbow body 1 expands to prevent the elbow body 1 from cracking and damage caused by stress generated by thermal expansion.

[0034] Reference Figures 4 to 5 In one aspect of this embodiment, a connection box No. 1 301 is fixedly installed on the upper surface and both sides of the protection box 202, a fixing plate 302 is fixedly installed on the top of the inner wall of the connection box No. 1 301, and a limiting block 303 is slidably connected to the inner wall surface of the fixing plate 302.

[0035] A No. 1 spring 304 is fixedly mounted on the upper surface of the limiting block 303 , and the other end of the No. 1 spring 304 is fixedly connected to the top of the inner wall of the No. 1 connection box 301 .

[0037] Connecting plates 307 are fixedly installed on both ends of the inner wall of the slide bar 306 , a No. 2 spring 308 is fixedly installed on one side of the connecting plate 307 , and the other end of the No. 2 spring 308 is fixedly connected to one side of the inner wall of the No. 2 connecting box 305 .

[0038] In this embodiment, the slide rod 306 is pushed so that the slide rod 306 squeezes the limit block 303, causing the No. 1 spring 304 to retract and drive the limit block 303 to rise. At the same time, the No. 2 spring 308 is stretched. After the slide rod 306 slides to a suitable position, the No. 1 spring 304 rebounds and drives the limit block 303 to move, so that the limit block 303 and the slide rod 306 are engaged to connect and fix the two protective boxes 202.

[0039] Working principle: When the device is used, the protective box 202 should be placed on both sides of the elbow body 1 so that the fixing ring 201 is slidably connected to the inner wall surface of the protective box 202, and then the slide bar 306 is pushed to squeeze the limit block 303 so that the No. 1 spring 304 retracts and drives the limit block 303 to rise, and at the same time, the No. 2 spring 308 is stretched. After the slide bar 306 slides to the appropriate position, the No. 1 spring 304 rebounds and drives the limit block 303 to move so that the limit block 303 is engaged with the slide bar 306 to connect and fix the two protective boxes 202. When the device is used, when the elbow body 1 transports steam or hot water and causes the elbow body 1 to expand under force, the protective box 202 can limit the elbow body 1 to prevent it from moving, and at the same time, the buffer plate 204 can deform as the elbow body 1 expands to prevent the elbow body 1 from cracking and damage due to stress generated by thermal expansion.
