[0001] The utility model relates to the technical field of perlite smoke exhaust and ventilation pipes, and particularly relates to an integrated assembled perlite smoke exhaust and ventilation pipe. Background Technique

[0002] The perlite smoke exhaust and ventilation pipe is a ventilation pipe with special properties and is widely used in the smoke exhaust and ventilation systems in fields such as buildings and industries.

[0003] When such perlite smoke exhaust and ventilation pipes in the prior art are in use, they are generally installed between adjacent pipes through bolts and screws. After a section of perlite smoke exhaust and ventilation pipe is installed, its length is fixed. For the entire project, a large number of screws are often required for installation, resulting in a low overall installation efficiency of the device. Therefore, an integrated assembled perlite smoke exhaust and ventilation pipe is needed to improve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrated assembled perlite smoke exhaust and ventilation pipe to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An integrated assembled perlite smoke exhaust and ventilation pipe, including a smoke exhaust and ventilation pipe body. A wind channel is arranged inside the smoke exhaust and ventilation pipe body. Fixed rings are fixedly arranged at both ends of the surface of the smoke exhaust and ventilation pipe body. A locking mechanism for fixing the fixed rings is arranged outside the fixed rings. The locking mechanism includes a fixed frame, a connecting rod, a hanging ear, a fixed block, a wrench, and a buckle. The outer surface of the fixed ring is sleeved with the fixed frame. The connecting rod is fixedly arranged on the surface of the fixed frame. The hanging ear is fixedly arranged at one end of the connecting rod away from the fixed frame. The fixed block is fixedly arranged on the outer surface of the smoke exhaust and ventilation pipe body. One side of the upper end of the fixed block is movably arranged with a wrench through a rotating shaft. The buckle is movably arranged in the middle of the inner side of the wrench through a rotating shaft.

[0006] Preferably, a sealing rubber ring is arranged on the outer surface of the fixed ring. When the "C"-shaped fixed frame is sleeved on the outer surface of the fixed ring, it will tightly squeeze and drive the two fixed rings to fit closely together. At this time, the sealing rubber ring can increase the sealing performance between the fixed rings, thereby ensuring the sealing performance at the connection of the two smoke exhaust and ventilation pipes and ensuring the smoke exhaust quality.

[0007] Preferably, a locking groove is arranged inside the fixed frame. By sleeving the locking groove on the outer surface of the fixed ring, the fixed ring can be fixed, and thus the two smoke exhaust and ventilation pipe bodies can be fixed together.

[0008] Preferably, the buckle is sleeved on the outer surface of the hanging ear. By rotating the wrench, the wrench lies flat, and then the buckle can be driven to be sleeved on the outer surface of the hanging ear, so as to play a role in fixing the hanging ear. After the hanging ears on the left and right fixed frames are fixed by the buckle, they cannot move left and right, so they cannot break away from the flange on the surface of the fixing ring, thus ensuring the stability of the fixed frame after fixing the fixing ring.

[0009] Preferably, buckles are arranged at both the upper end and the lower end of the outer surface of the main body of the smoke exhaust and prevention air duct. In this way, the stability of the buckle for fixing the hanging ear can be ensured by the upper and lower buckles.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The present invention changes the traditional screw-connected smoke exhaust and prevention air duct to a fixing method by clamping with a special buckle. When facing the installation and fixing of a long string of smoke exhaust and prevention air ducts in a project, the installation efficiency can be greatly improved.

[0012] 2. The overall operation of the present invention is convenient, the installation is simple, and no complex training is required. The staff can easily install it, so it is convenient to promote and use. Description of the Drawings

Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3, the utility model provides a technical solution: an integrated prefabricated floating bead smoke exhaust and prevention air duct, including a smoke exhaust and prevention air duct body 1, a duct 2 is arranged inside the smoke exhaust and prevention air duct body 1, fixing rings 3 are fixedly arranged at both ends of the surface of the smoke exhaust and prevention air duct body 1, and a locking mechanism for fixing the fixing rings 3 is arranged outside the fixing rings 3. The locking mechanism includes a fixing frame 4, a connecting rod 5, a hanging ear 6, a fixing block 7, a wrench 8, and a buckle 9. The fixing frame 4 is sleeved on the outer surface of the fixing ring 3, the connecting rod 5 is fixedly arranged on the surface of the fixing frame 4, the hanging ear 6 is fixedly arranged at one end of the connecting rod 5 away from the fixing frame 4, the fixing block 7 is fixedly arranged on the outer surface of the smoke exhaust and prevention air duct body 1, a wrench 8 is movably arranged at one side of the upper end of the fixing block 7 through a rotating shaft, and a buckle 9 is movably arranged in the middle of the inner side of the wrench 8 through a rotating shaft.

[0019] A sealing rubber ring is arranged on the outer surface of the fixing ring 3. When the "C"-shaped fixing frame 4 is sleeved on the outer surface of the fixing ring 3, it will tightly squeeze and drive the two fixing rings 3 to fit closely with each other. At this time, the sealing performance between the fixing rings 3 can be increased under the action of the sealing rubber ring; thus, the sealing performance at the connection of the two smoke exhaust and prevention air ducts can be ensured to guarantee the smoke exhaust quality.

[0020] A locking groove 10 is arranged inside the fixing frame 4. By sleeving the locking groove 10 on the outer surface of the fixing ring 3, the fixing ring 3 can be fixed, and thus the two smoke exhaust and prevention air duct bodies 1 can be fixed together.

[0021] The buckle 9 is sleeved on the outer surface of the hanging ear 6. By rotating the wrench 8 to make the wrench 8 lie flat, the buckle 9 can be driven to be sleeved on the outer surface of the hanging ear 6, thus playing a role in fixing the hanging ear 6; after the hanging ears 6 on the left and right fixing frames 4 are fixed by the buckle 9, they cannot move left and right, and thus cannot be separated from the flange on the surface of the fixing ring 3, so as to ensure the stability after the fixing frame 4 fixes the fixing ring 3.

[0022] Buckles 9 are arranged at both the upper end and the lower end of the outer surface of the smoke exhaust and prevention air duct body 1. In this way, the stability of the buckle 9 for fixing the hanging ear 6 can be ensured by the upper and lower two buckles 9.

[0023] Working principle: When using this device, the connection of the smoke prevention and exhaust air duct body 1 of this device is different from the traditional connection method. The fixing method through bolts and screws is omitted, and it is changed to an integrated quick splicing and installation. When installing, align the fixing ring 3, and then when the "C"-shaped fixing frame 4 is sleeved on the outer surface of the fixing ring 3, it will tightly squeeze and drive the two fixing rings 3 to fit closely together. At this time, the sealing rubber ring can increase the sealing performance between the fixing rings 3; thus, the sealing performance at the connection of the two smoke prevention and exhaust air ducts can be ensured to guarantee the smoke exhaust quality. And after the fixing frame 4 is completely sleeved on the outer surface of the fixing ring 3, the two lugs 6 will be spliced together. Then, make the wrench 8 lie flat, and immediately the buckle 9 can be driven to be sleeved on the outer surface of the lug 6, so as to play a role in fixing the lug 6; and after the lugs 6 on the left and right fixing frames 4 are fixed by the buckle 9, they cannot move left and right, so they cannot be separated from the flange on the surface of the fixing ring 3, thus ensuring the stability after the fixing frame 4 fixes the fixing ring 3; in this way, this device changes the traditional screw-connected smoke prevention and exhaust air ducts to be fixed by the clamping method of the special buckle 9. When facing the installation and fixing of a long string of smoke prevention and exhaust air ducts in a project, the installation efficiency can be greatly improved.
