Technical Field

[0001] The utility model relates to the technical field of angle iron flanges, in particular to a reinforcement structure and an angle iron flange. Background Art

[0002] Angle iron flange is a metal connector used to connect pipes, air ducts or other equipment. It is usually made of angle iron through cutting, punching, welding and other processing techniques. Angle iron flange has the advantages of simple structure, durability and easy installation. It is widely used in ventilation and air-conditioning systems, fire protection pipe systems, industrial pipes and other fields. The connection method of angle iron flange is generally to fasten the two flanges together with bolts, and a sealing gasket will be placed in the middle to ensure the sealing of the connection.

[0003] The connection between the existing angle iron flange and the pipeline usually adopts a layer of metal cylinder. However, when only one layer of structure is used, it is easy for strong pressure to cause deformation of the metal cylinder during operation. When the metal cylinder is deformed, it is easy to cause air leakage at the connection between the angle iron flange and the pipeline, thereby affecting the connection of the pipeline and failing to meet people's use needs. In view of the above situation, technical innovation is carried out on the basis of the existing reinforced structure and angle iron flange. Utility Model Content

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a reinforcement structure and an angle iron flange include an angle reinforcement strip 2 and a tightening assembly 4. An outer hook protective cover assembly 3 is arranged outside the reinforcement strip 2. The tightening assembly 4 is installed outside the outer hook protective cover assembly 3. The reinforcement strip 2 is distributed in an annular shape inside the outer hook protective cover assembly 3, and the shape of the reinforcement strip 2 is wavy.

[0021] By setting the reinforcing strip 2 between the outer protective cover assembly 3 and the angle iron flange body 1, a double-layer structure is formed by the outer protective cover assembly 3 and the angle iron flange body 1, and the pipeline part is still connected to the angle iron flange body 1, so that when the equipment is subjected to strong pressure, only the outer protective cover assembly 3 will be damaged, and the shape of the angle iron flange body 1 will not be affected, thereby ensuring that the connection between the angle iron flange body 1 and the pipeline will not be deformed, ensuring the tightness of the equipment connection, and at the same time, the reinforcing strip 2 is a triangular structure, and the reinforcing strip 2 can also have a strong supporting effect on the outer protective cover assembly 3, thereby ensuring the integrity of the outer protective cover assembly 3, which can further reduce the occurrence of damage to the equipment due to overpressure.

[0022] like Figure 1 As shown, the outer protective cover assembly 3 includes a fixed cover plate 301 and a telescopic ring 302, and one end of the fixed cover plate 301 is connected to the telescopic ring 302, the outer protective cover assembly 3 also includes a movable cover plate 303 and fixed barbs 304, and the side of the telescopic ring 302 away from the fixed cover plate 301 is connected to the movable cover plate 303, and the side of the movable cover plate 303 away from the telescopic ring 302 is provided with a fixed barb 304, a telescopic structure is formed between the telescopic ring 302 and the fixed cover plate 301, and the telescopic ring 302 and the movable cover plate 303 are integrally connected;

[0023] The movable cover plate 303 is provided with fixed barbs 304, and the tightening outer cover 401 forms an elastic structure with the connecting block 403 through a small strong spring 402, so that the movable cover plate 303 can exert a greater traction force on the connected pipe, thereby ensuring the stability of the pipe connection on the equipment.

[0024] like Figure 4As shown, the tightening assembly 4 includes a tightening cover 401, a small strong spring 402 and a connecting block 403, and the small strong spring 402 is arranged inside the tightening cover 401, and the end of the small strong spring 402 away from the tightening cover 401 is connected to the connecting block 403, the tightening assembly 4 also includes a connecting ball 404 and a threaded collar 405, and the connecting ball 404 is connected inside the connecting block 403, and the end of the connecting ball 404 away from the small strong spring 402 is connected to the threaded collar 405;

[0025] The threaded connection between the threaded collar 405 and the fixed cover plate 301 can pull the movable cover plate 303 when the threaded collar 405 is rotated, so that the movable cover plate 303 and the angle iron flange body 1 cooperate to squeeze the connection of the pipeline, thereby increasing the tightness of the equipment connection.

[0026] An angle iron flange comprises an angle iron flange body 1, and the angle iron flange body 1 is installed with a reinforcement structure as described above.

[0027] Working principle: When using the reinforcement structure and angle iron flange, first insert the pipe to be connected into the movable cover plate 303, so that the end of the pipe is sleeved on the angle iron flange body 1, and then push the pipe with force to wrap the pipe around the angle iron flange body 1 to achieve connection. At this time, rotate the threaded ring 405, and move the threaded ring 405 through the threaded connection between the fixed cover plate 301 and the threaded ring 405, so that the movable cover plate 303 is pulled by the connecting ball 404, the connecting block 403, the small strong spring 402 and the tightening outer cover 401, so that the movable cover plate 303 cooperates with the angle iron flange body 1 to squeeze and fix the pipe sleeved on the angle iron flange body 1, and the movable cover plate 303 can be tightly pulled by the setting of the fixed barb 304 to avoid insufficient friction between the pipe and the movable cover plate 303, which affects the connection effect. At the same time, a telescopic structure is formed between the telescopic ring 302 and the fixed cover plate 301, and the telescopic structure can make the telescopic ring 30 2 plays a guiding role for the movable cover plate 303, making it easier for the movable cover plate 303, the fixed cover plate 301 and the angle iron flange body 1 to be on the same horizontal center line, so that the movable cover plate 303 and the angle iron flange body 1 cooperate to fix the pipeline. At the same time, the outer cover 401 is tightened to form an elastic structure between the small strong spring 402 and the connecting block 403. Through the elastic structure, the outer cover 401 can still provide a continuous traction force to the movable cover plate 303 after the equipment is installed, thereby increasing the stability of the movable cover plate 303 and the angle iron flange body 1 to fix the pipeline. At the same time, the connecting ball 404 and the connecting block 403 are movably connected, so that when the movable cover plate 303 squeezes the pipeline, the movable cover plate 303 will no longer rotate, while the threaded collar 405 can still rotate, thereby facilitating the threaded collar 405 to continue to move, providing traction force to the small strong spring 402, so that the small strong spring 402 can store a certain traction force.
