[0002] In order to prevent the roof from cracking due to water freezing or gas pressure, exhaust holes are usually reserved on the roof during construction. Exhaust pipes extending to the outside of the roof are connected to the exhaust holes to discharge the gas in the insulation layer in time. However, during exterior wall construction, the exhaust pipes extending out of the roof are prone to tilting or breaking due to lack of effective support, which affects the normal exhaust of the roof and interferes with the normal construction of the exterior wall. Utility Model Content

[0020] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0021] Reference Figure 1 and Figure 2 The cam 2 is provided with a plurality of fixing rods 3 which are welded or integrally formed on one end of the cam 2 and fixed to the wall, thereby ensuring the firmness of the cam 2 and improving the protection effect. The cam 7 is fixed to the wall after being bored, so that the protective tube 2 and the telescopic tube 4 are both sufficiently firm. The interior of the telescopic tube 4 is connected to a plurality of support rods 7 by means of a pin or hinge. The ends of the support rods 7 are in contact with the outer wall of the exhaust pipe 1 by rotation. Such a structure enables the support rods 7 to contact with the outer wall of the exhaust pipe 1 by rotation, thereby effectively supporting the exhaust pipe 1. When wind or manpower acts on the exhaust pipe 1, the exhaust pipe 1 is not easily bent or broken, further ensuring the integrity of the exhaust pipe 1. The interior of the telescopic tube 4 is provided with a plurality of adjusting rods 8 for driving the support rods 7 to rotate. The adjusting rods 8 are used to control the rotation of the support rods 7, so that when the telescopic tube 4 is moved horizontally and installed, the support rods 7 can avoid the exhaust pipe 1, thereby avoiding possible interference with the exhaust pipe 1 during installation. After installation, the adjusting rods 8 are used to control the support rods 7 to rotate in the opposite direction until they contact the outer wall of the exhaust pipe 1, thereby effectively supporting the exhaust pipe 1, improving the convenience of installation, and further improving the effectiveness of protecting the exhaust pipe 1.

[0022] Preferably, the end of the support rod 7 is fixed with a contact plate 9 that contacts the outer wall of the exhaust pipe 1 by welding or integral molding. The contact plate 9 is an arc-shaped shape that adapts to the shape of the outer wall of the exhaust pipe 1. Such a structure makes the contact area between the support rod 7 and the outer wall of the exhaust pipe 1 larger, thereby improving the supporting effect on the exhaust pipe 1 and further improving the stability of the exhaust pipe 1.

[0023] Preferably, refer to Figure 3 and Figure 4 The support rod 7 is rotatably connected to an adjusting sleeve 10 through a pin or a hinge, and the adjusting rod 8 is slidably connected in the adjusting sleeve 10. One end of the adjusting rod 8 is rotatably connected to the inner wall of the telescopic cylinder 4 through a pin or a hinge. With this structure, when the support rod 7 is rotated and adjusted, it is only necessary to slide the adjusting rod 8 in the adjusting sleeve 10 so that the overall length of the two changes, thereby enabling the support rod 7 to rotate. In this process, the whole composed of the adjusting rod 8 and the adjusting sleeve 10 rotates relative to the support rod 7 and the inner wall of the telescopic cylinder 4, further simplifying the steps of rotating and adjusting the support rod 7 and improving the convenience of controlling the rotation of the support rod 7.

[0024] Preferably, a rotating block 11 is rotatably connected to the inner wall of the telescopic cylinder 4 through a pin or a hinge, one end of the adjusting rod 8 is rotatably connected to the rotating block 11 through a bearing, and the other end of the adjusting rod 8 is threadedly connected to the inside of the adjusting sleeve 10. Such a structure only needs to rotate the adjusting rod 8 to drive the adjusting rod 8 toward the inside of the adjusting sleeve 10 or toward the direction away from the adjusting sleeve 10 under the action of the threaded connection, thereby achieving adjustment of the overall length of the adjusting rod 8 and the adjusting sleeve 10, thereby achieving rotation control of the support rod 7, and after adjustment, the threaded connection is used to ensure effective support for the rotation structure of the support rod 7, further improving the convenience of adjustment and the firmness of the rotation structure of the support rod 7.

[0025] Preferably, the telescopic cylinder 4 is threadedly connected to the outside of the protective cylinder 2. Such a structure makes it more convenient to move and adjust the telescopic cylinder 4 relative to the protective cylinder 2. It is only necessary to rotate the external telescopic cylinder 4 to allow it to move axially relative to the protective cylinder 2 under the action of the threaded connection. The threaded connection between the two makes the overall structure more stable, thereby ensuring the protection effect of the exhaust pipe 1.

[0026] Preferably, the protective tube 2 and the telescopic tube 4 are both made of metal. Metal has a high structural strength and can provide sufficient protection. It is also common in construction and can be made using discarded pipes, further reducing the difficulty of manufacturing the device and facilitating widespread promotion and use.

[0027] Working principle: The utility model sets a protective tube 2 on the outside of the exhaust pipe 1, and the protective tube 2 is fixed to the wall by multiple fixing rods 3 at the end, so as to achieve effective protection for the exhaust pipe 1 extending out of the roof, and avoid damage to the exhaust pipe 1 caused by workers or falling objects during exterior wall construction, thereby ensuring the smooth flow of building exhaust. In addition, a telescopic tube 4 that moves in the axial direction is provided on the outside of the protective tube 2, and the telescopic tube 4 is fixed to the wall by an inclined rod 5. The setting of the telescopic tube 4 can be moved relative to the protective tube 2 according to actual use needs, thereby achieving adaptive protection for exhaust pipes 1 of different lengths, broadening the scope of application of the device, and further improving the application of different buildings. The adaptability of the building; the internal rotation of the telescopic cylinder 4 is connected to multiple support rods 7, and the ends of the support rods 7 are in contact with the outer wall of the exhaust pipe 1. The support rods 7 are rotated and adjusted by using the adjusting rods 8. This structure allows the support rods 7 to rotate toward the inner wall of the telescopic cylinder 4 during installation, so that the support rods 7 will not interfere with the internal exhaust pipe 1 during installation. After installation, the support rods 7 are rotated in the opposite direction using the adjusting rods 8 so that the ends of the support rods 7 are in contact with the outer wall of the exhaust pipe 1, thereby achieving effective support for the exhaust pipe 1, preventing the exhaust pipe 1 from tilting or breaking due to external wind or human force, and further improving the protection effect of the exhaust pipe 1.
