[0002] In the field of industrial waste gas treatment, various factories generate a large amount of waste gas, which needs to be transported through pipelines to purification equipment for treatment before discharge. Traditional waste gas pipes are usually assembled by welding and flange connections.

[0003] However, flange connection installation requires personnel to accurately locate the installation holes, which is time-consuming and labor-intensive. Therefore, it is necessary to improve the existing technology to solve the above problems. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figures 1-4 , an exhaust pipe that is easy to install, includes an outer tube body 1, an inner tube body 9 is welded inside the outer tube body 1, and one end of the inner tube body 9 extends out of the outer tube body 1, and the outer side of the inner tube body 9 is provided with two symmetrically distributed card grooves 10 at a position outside the outer tube body 1, and the outer side of the outer tube body 1 is provided with two symmetrically distributed sliding openings at a position away from the inner tube body 9, and a fixing block 13 is fixed in the sliding opening by bolts, and a card block 6 is slidably connected in the sliding opening, and the card block 6 is engaged with the card groove 10, and one side of the card block 6 is integrally formed with an inclined surface, and a spring 11 is provided in the sliding opening, and the two ends of the spring 11 are respectively fixed to the card block 6 and the fixing block 13, and the outer side of the outer tube body 1 is welded with flanges 4 at both ends, and a plurality of mounting holes 8 are provided on one side of the flange 4, and the inner tube body 9 on one outer tube body 1 is inserted into the other outer tube body 1, and in the process of inserting the inner tube body 9 into the outer tube body 1, the inner tube body 9 will contact the inclined surface of the block 6. At this time, the inner tube body 9 will push the block 6 to move into the sliding mouth through the inclined surface of the block 6, and the block 6 will squeeze the spring 11. When the flanges 4 on the two outer tube bodies 1 are in contact, one of the outer tube bodies 1 is rotated at this time, and the outer tube body 1 will drive the inner tube body 9 to rotate. When the inner tube body 9 is rotated until the block 6 is aligned with the slot 10, the block 6 will be inserted into the slot 10 under the force of the spring 11. At this time, the mounting holes 8 on the fitting flanges 4 will be aligned, which facilitates positioning of the mounting holes 8 on the flanges 4 and saves time. At the same time, by snapping the block 6 into the slot 10, the two outer tube bodies 1 can be auxiliary fixed, thereby improving the stability of the exhaust pipe assembly.

[0023] In the present invention, a stepped protrusion is integrally formed at one end of the outer tube body 1, and a sealing rubber ring 5 is bonded to each layer of the stepped protrusion. A slot adapted to the stepped protrusion is provided at the other end of the outer tube body 1. During the insertion of the inner tube body 9, the stepped protrusion on the outer tube body 1 is inserted into the slot on the other outer tube body 1. When the two outer tube bodies 1 are assembled, the sealing rubber ring 5 on the stepped protrusion seals the gap between the two outer tube bodies 1, thereby performing multiple sealing on the two outer tube bodies 1 and improving the sealing effect of the exhaust pipe assembly.

[0024] In particular, a plurality of mounting grooves 2 are provided on one side of the flange 4, and magnetic blocks 3 are bonded in the plurality of mounting grooves 2. When the mounting holes 8 on the fitting flanges 4 are aligned, the magnetic blocks 3 on the two flanges 4 are adsorbed, thereby assisting in fixing the two outer tube bodies 1 again, greatly improving the stability of the exhaust pipe assembly. A square rod 12 is welded at one end of the block 6, and the square rod 12 passes through the spring 11 and the fixed block 13. A limit block 7 is welded at one end of the square rod 12 for pulling the square rod 12 to move and limit the block 6. In the process of the block 6 being reset by the spring 11, the block 6 is limited by the contact between the limit block 7 and the fixed block 13 to prevent the block 6 from moving through the slot 10.

[0025] Working principle: When assembly is required, the inner tube body 9 on one of the outer tube bodies 1 is inserted into the other outer tube body 1. During the process of inserting the inner tube body 9 into the outer tube body 1, the inner tube body 9 will contact the inclined surface on the block 6. At this time, the inner tube body 9 will push the block 6 to move into the sliding mouth through the inclined surface of the block 6. The block 6 will squeeze the spring 11. When the flanges 4 on the two outer tube bodies 1 are fitted together, one of the outer tube bodies 1 is rotated, and the outer tube body 1 will drive the inner tube body 9 to rotate. When the inner tube body 9 is rotated until the block 6 is aligned with the slot 10, the block 6 will be inserted into the slot 10 under the action of the spring 11. At this time, they are in close contact. The mounting holes 8 on the flange 4 will be aligned, which makes it easy to position the mounting holes 8 on the flange 4 and saves time. At the same time, the clamping block 6 is clamped into the clamping groove 10, which can assist in fixing the two outer tube bodies 1 and improve the stability of the exhaust pipe assembly. In the process of inserting the inner tube body 9, the stepped protrusion on the outer tube body 1 will be inserted into the slot on the other outer tube body 1. When the two outer tube bodies 1 are assembled, the sealing rubber ring 5 on the stepped protrusion will seal the gap between the two outer tube bodies 1, thereby performing multiple sealing on the two outer tube bodies 1 and improving the sealing effect of the exhaust pipe assembly.

[0026] In addition, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
