A fixing device 6 is provided on the side surfaces of the connecting frame 4 and the second pipeline 2, and a clamping device 5 is provided on the bottom surface of the first pipeline 1.
[0028] The following specifically describes the specific settings and functions of its fixing device 6 and clamping device 5.
[0029] Referring to Figure 2 and Figure 3As shown in the figure, in this embodiment: The fixing device 6 includes a rotating frame 601. One end of the rotating frame 601 is fixedly connected to the connecting frame 4. The inner wall of the rotating frame 601 is rotatably connected to a rotating plate 603. A screw rod 608 threadedly penetrates through one end of the rotating plate 603 away from the rotating frame 601. A sliding plate 606 is slidably connected to the surface of the rotating plate 603. One end of the sliding plate 606 away from the rotating frame 601 is rotatably connected to the screw rod 608. On both sides of one end of the sliding plate 606, limiting columns 607 are fixedly connected. At a position corresponding to the rotating plate 603 on the side surface of the second pipe 2, a fixing frame 604 is fixedly connected. At a position corresponding to the limiting columns 607 on the side surface of the fixing frame 604, limiting holes 605 are provided. The inner wall of the limiting hole 605 is slidably connected to the arc surface of the limiting column 607. By providing the fixing device 6, the operator can quickly fix and disassemble the two pipes by operating the rotating plate 603 and the screw rod 608, achieving the effects of convenient use, simple operation, and strong practicability. A coil spring 602 is slidably connected to the inner wall of the rotating frame 601. Both ends of the coil spring 602 are fixedly connected to the rotating frame 601 and the rotating plate 603 respectively. The torsional force generated by the coil spring 602 can squeeze and limit the position of the rotating plate 603, thereby avoiding the shaking of the position of the rotating plate 603. On the arc surface of one end of the screw rod 608, a number of anti-slip lines 611 are provided. The number of anti-slip lines 611 are evenly distributed on the arc surface of the screw rod 608, increasing the friction between the hand and the screw rod 608, preventing hand slippage, and playing the role of use. At both ends of the bottom surface of the second pipe 2, positioning rods 609 are fixedly connected. The cross-section of the positioning rod 609 is in an "L" shape. At a position corresponding to the positioning rod 609 on the bottom surface of the connecting frame 4, a positioning plate 610 is fixedly connected. The arc surface of one end of the positioning rod 609 is slidably connected to the inner wall of the positioning rod 609, playing a supporting role between the second pipe 2 and the connecting frame 4 and improving stability.
[0030] Refer to Figure 4As shown in the figure, in this embodiment: The clamping device 5 includes a fixing plate 51. The bottom surface of the fixing plate 51 is fixedly connected to the first pipe 1. A rotating rod 53 is threadedly penetrated through the inner wall of the fixing plate 51. Threads in opposite directions are provided on the arc surface of the rotating rod 53. One end of the rotating rod 53 is rotatably connected to a limiting plate 52. The bottom surface of the limiting plate 52 is fixedly connected to the first pipe 1. Two clamping plates 55 are threadedly connected to the arc surface of the rotating rod 53. A limiting frame 56 is slidably connected to the inner wall of the clamping plate 55. One end surface of the limiting frame 56 is fixedly connected to the first pipe 1. A positioning column 54 is fixedly connected to the bottom surface of the filter net 3 at a position corresponding to the clamping plate 55. The arc surface of the positioning column 54 abuts against one end surface of the clamping plate 55. By providing the clamping device 5, the operator only needs to rotate the rotating rod 53 to quickly use the clamping device 5, preventing the filter net 3 from sliding out of the first pipe 1, reducing potential safety hazards, improving safety. A plurality of friction grooves 57 are provided on the arc surface at the other end of the rotating rod 53. The plurality of friction grooves 57 are evenly distributed on the arc surface of the rotating rod 53, increasing the friction between the hand and the rotating rod 53, preventing the hand from slipping, and facilitating the use of the rotating rod 53. The rotating rod 53 is made of stainless steel, and the fixing plate 51 is made of stainless steel, reducing the oxidation efficiency between the rotating rod 53 and the fixing plate 51 and preventing rust and inconvenient use.
[0031] The working principle of a kind of aluminosilicate anti-smoke and heat-resistant exhaust pipe provided by the utility model is as follows. When it is necessary to connect two exhaust pipes, first slide the positioning rod 609 on the bottom surface of the second pipe 2 into the positioning plate 610, and then rotate the rotating plate 603 onto the fixing frame 604. The torsional force generated by the coil spring 602 during this process can squeeze and limit the position of the rotating plate 603, thereby avoiding the shaking of the position of the rotating plate 603. Then rotate the screw 608, and the screw 608 drives the sliding plate 606 to move. The sliding plate 606 drives the limiting column 607 to move until the limiting column 607 slides into the limiting hole 605, realizing the fixing effect between the two pipes.
[0032] When sliding the filter net 3 into the first pipe 1 again, rotate the rotating rod 53. The rotating rod 53 drives the clamping plate 55 to move towards the positioning column 54. During this process, the limiting frame 56 prevents the clamping plate 55 from rotating during the movement. When the clamping plate 55 is in pressing contact with the positioning column 54, the fixing effect between the filter net 3 and the first pipe 1 is realized.
[0033] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
