TECHNICAL FIELD
[0001] The utility model relates to the technical field of air pipe equipment, especially to a fireproof air pipe convenient to install. BACKGROUND
[0002] Air pipes are commonly used for ventilation and are divided into industrial and household air pipes, and the special performance requirements of air pipes are different under different conditions, but the research on fireproof and heat insulation has always been the focus of fire disaster prevention. Air pipes have poor fireproof and heat insulation performance, on the one hand, if a fire occurs, the fire can easily be sprayed along the inside of the air pipe, causing a huge heat wave impact, burning objects, and endangering personal safety, etc. Therefore, people have conducted a lot of research on composite air pipes with fireproof and heat insulation.
[0003] For example, the Chinese utility model patent with patent application number CN202020653029.0 discloses a fireproof air pipe, which comprises an air pipe body, a keel, a fire-resistant plate, a glass wool board, a self-tapping screw, and a suspension mechanism. The keel is installed on the air pipe body, the fire-resistant plate is installed on the keel, the glass wool board is installed on the fire-resistant plate, and the suspension mechanism is installed on the glass wool board. The self-tapping screw is connected to the keel after passing through the glass wool board and the fire-resistant plate. In the utility model, the keel can fix the shape of the air pipe body to improve the load-bearing capacity and strength of the air pipe. The fire-resistant plate and the glass wool board are not easy to burn, which can effectively reduce the probability of burning caused by the high temperature of the airflow conveyed in the utility model. In addition, they have good heat insulation effect, which can effectively prevent the fireproof air pipe from burning due to high temperature from the outside.
[0004] For example, the Chinese utility model patent with patent application number CN202223032716.9 discloses a fireproof air pipe, which belongs to the technical field of air pipes. The fireproof air pipe comprises an air pipe shell, a ventilation pipe fixedly connected to the inner wall of the air pipe shell, fireproof cotton arranged at the end of the air pipe shell and the ventilation pipe and attached to the inner wall of the air pipe shell, and a fixing mechanism comprising a fixed partition plate, a through hole, a limiting circular groove, a threaded sleeve, a limiting circular plate, a bolt, and a clamping plate. The fixed partition plate is fixedly connected to the side end of the ventilation pipe, the through hole is formed in the side end of the air pipe shell, the fireproof cotton, and the fixed partition plate, and is attached to the inner wall of the air pipe shell for fireproofing. The fireproof cotton has good elasticity and will not be torn due to impact, which can reduce the sealing performance of the fireproof cotton. In addition, the fireproof cotton can be replaced according to the effective use time.
[0005] Because fireproof ducts come in various sizes, existing fireproof ducts typically cannot adjust the diameter between the first and second connectors during use, which reduces their versatility. Secondly, fireproof ducts require installation, and existing ducts are not stable or easy to install, which can easily lead to displacement within the first and second connectors during use, reducing the stability of the fireproof duct and making it prone to loosening.

[0025] like Figure 1 As shown, the fireproof duct that is easy to install includes a first connector 1, a second connector 101 is provided on the surface of the first connector 1, and a duct body 102 is provided on the surfaces of the first connector 1 and the second connector 101. One end of the duct body 102 extends into the interior of the first connector 1 and the second connector 101.
[0026] Furthermore, such as Figure 2 and Figure 4As shown, both the first connector 1 and the second connector 101 are provided with a stabilizing mounting mechanism 3. The stabilizing mounting mechanism 3 includes a push-pull rod 301, a extension spring 302, and a stabilizing mounting part 303. The stabilizing mounting part 303 is provided on the surface of the first connector 1 and the second connector 101, and is composed of a spring body 3031, an arc-shaped clip 3032, an anti-detachment pad 3033, and an arc-shaped clamping plate 3034. Both the first connector 1 and the second connector 101 are provided with a push-pull rod 301. One end of the push-pull rod 301 passes through the first connector 1 and the second connector 101 and extends into the interior of the first connector 1 and the second connector 101. An arc-shaped clamping plate 303 is installed on the surface of the push-pull rod 301. 034, an anti-detachment pad 3033 is adhered to the inner wall of the arc-shaped clamp 3034. The surface of the anti-detachment pad 3033 is in contact with the surface of the duct body 102. An extension spring 302 is installed on the inner wall of each push-pull rod 301. One end of the extension spring 302 is fixed to the surface of the first connector 1 and the second connector 101 respectively. A groove is opened on the surface of each push-pull rod 301. An arc-shaped clip 3032 is provided inside the groove. The arc-shaped clip 3032 slides and engages with the inner wall of the groove. The arc-shaped clip 3032 engages with the inner wall of the first connector 1 and the second connector 101. A spring body 3031 is installed on the surface of each arc-shaped clip 3032. One end of the spring body 3031 is fixed to the inner wall of the groove.
[0027] During implementation, the user pulls the push-pull rod 301. Under the elastic force of the extension spring 302, the push-pull rod 301 moves along the inner wall of the first connector 1 and the second connector 101. The user places the duct body 102 on the surface of the first connector 1 and the second connector 101, so that one end of the duct body 102 is inserted into the interior of the first connector 1 and the second connector 101. At this time, under the elastic force of the extension spring 302, the push-pull rod 301 moves the arc-shaped clamp 3034 and the anti-detachment pad 3033, causing the arc-shaped clamp 3034 to move the anti-detachment pad 3033 to the point where it is aligned with the inner wall of the first connector 1 and the second connector 101. The surfaces of the duct body 102 are in contact with each other. Under the elastic force of the spring body 3031 inside the groove, the arc-shaped clamp 3032 moves, causing the arc-shaped clamp 3032 to lock onto the inner wall of the corresponding first connector 1 and second connector 101. Under the combined action of the arc-shaped clamp 3034 and the anti-detachment pad 3033, the duct body 102 is clamped inside the first connector 1 and the second connector 101, preventing the duct body 102 from loosening from the inside of the first connector 1 and the second connector 101, so as to achieve the function of securely installing the duct body 102 and making the installation more convenient.
[0028] Furthermore, such as Figure 3 and Figure 5As shown, both the first connecting member 1 and the second connecting member 101 are provided with an adjusting diameter mechanism 4. The adjusting diameter mechanism 4 includes a fixing screw 401, a fastening bolt 402, and an adjusting diameter assembly 403. The adjusting diameter assembly 403 is provided on the surface of the first connecting member 1 and the second connecting member 101, and is composed of a nail body 4031, an adjusting screw cylinder 4032, and a support base 4033. The inner wall of the first connecting member 1 is equipped with a fixing screw 401, and the adjusting screw cylinder 4032 is threaded onto the surface of the fixing screw 401. The adjusting screw cylinder 4032 and the surface of the fixing screw 401 are rotatably engaged with each other. The adjusting screw 4032 is threaded with a fastening bolt 402. One end of the fastening bolt 402 passes through the adjusting screw 4032 and is threadedly fastened to the surface of the fixing screw 401. A support seat 4033 is provided on the surface of the bottom position of the adjusting screw 4032. The surface of the support seat 4033 and the surface of the adjusting screw 4032 rotate and cooperate with each other. The surface of the bottom position of the support seat 4033 is in contact with the surface of the second connecting member 101. The surface of the support seat 4033 is threaded with a nail body 4031. One end of the nail body 4031 passes through the support seat 4033 and is threadedly fastened to the surface of the second connecting member 101.
[0029] In practice, the user tightens the nail 4031 on the surface of the support base 4033, and the support base 4033 is installed on the surface of the second connector 101 under the action of the nail 4031. Then, the user loosens the fastening bolt 402 on the surface of the adjusting screw 4032, and then rotates the adjusting screw 4032 on the surface of the fixing screw 401, so that the adjusting screw 4032 drives the support base 4033 to move on the surface of the fixing screw 401. At this time, the adjusting screw 4032 drives the support base 4033 and the second connector 101 to adjust up and down to the required position, and adjusts the diameter between the first connector 1 and the second connector 101. After the adjustment is completed, the user tightens the fastening bolt 402 on the surface of the adjusting screw 4032, and the adjusting screw 4032 is fixed on the surface of the fixing screw 401 under the action of the fastening bolt 402, so as to realize the function of adjusting the diameter between the first connector 1 and the second connector 101 of the fireproof air duct.
[0030] Working principle: In use, first place the first connector 1 in the designated position. The user tightens the nail 4031 on the surface of the support base 4033. Under the action of the nail 4031, the support base 4033 is installed on the surface of the second connector 101. Then, the user loosens the fastening bolt 402 on the surface of the adjusting screw 4032, and then rotates the adjusting screw 4032 on the surface of the fixing screw 401. This causes the adjusting screw 4032 to drive the support base 4033 to move on the surface of the fixing screw 401. At this time, the adjusting screw 4032 drives the support base 4033 and the second connector 101 to move. Adjust the diameter between the first connector 1 and the second connector 101 to the desired position. After adjustment, tighten the fastening bolt 402 on the surface of the adjusting screw 4032. Under the action of the fastening bolt 402, the adjusting screw 4032 is fixed to the surface of the fixing screw 401, so as to realize the function of adjusting the diameter between the first connector 1 and the second connector 101 of the fireproof air duct. When in use, the size between the first connector 1 and the second connector 101 can be adjusted according to the diameter of the air duct body 102, making the fireproof air duct more versatile in use.
[0031] Subsequently, the user pulls the push-pull rod 301. Under the elastic force of the extension spring 302, the push-pull rod 301 moves along the inner wall of the first connector 1 and the second connector 101. The user places the duct body 102 on the surface of the first connector 1 and the second connector 101, so that one end of the duct body 102 is inserted into the interior of the first connector 1 and the second connector 101. At this time, under the elastic force of the extension spring 302, the push-pull rod 301 moves the arc-shaped clamp 3034 and the anti-detachment pad 3033, causing the arc-shaped clamp 3034 to move the anti-detachment pad 3033 until it is in contact with the surface of the duct body 102. Under the elastic force of the spring body 3031 inside the groove, the arc-shaped locking piece 3032 moves, causing the arc-shaped locking piece 3032 to lock into the corresponding... The inner walls of the first connector 1 and the second connector 101, under the combined action of the arc-shaped clamping plate 3034 and the anti-detachment pad 3033, clamp the duct body 102 inside the first connector 1 and the second connector 101, preventing the duct body 102 from loosening from the inside of the first connector 1 and the second connector 101, thus achieving the function of securely installing the duct body 102. The installation is more convenient and stable, and the duct body 102 can be securely installed inside the first connector 1 and the second connector 101. This prevents the duct body 102 from shifting inside the first connector 1 and the second connector 101 during use, making the fireproof duct more stable during use and less prone to loosening, ultimately completing the use of the fireproof duct.
