[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: an elliptical electric adjustable smoke damper, comprising a mounting frame 1 and a pipe 6, the pipe 6 is located at the outer ring of the mounting frame 1, a valve body 18 is arranged in the inner cavity of the mounting frame 1, mounting plates 2 are arranged on both sides of the mounting frame 1, connecting plates 8 are arranged on both sides of the pipe 6, a movable groove 13 is opened on one side of the mounting plate 2, a limit rod 15 is movably arranged in the inner cavity of the movable groove 13, one end of the limit rod 15 is connected to an L-shaped clamping plate 19, a threaded tube 10 is arranged on the back of the L-shaped clamping plate 19, and a sensor 17 is arranged on the upper front of the mounting frame 1.

[0023] The front surfaces of the mounting plate 2, the connecting plate 8 and the L-shaped clamping plate 19 are all penetrated with connecting holes 9, and the inner cavity of the connecting hole 9 is movably provided with a screw rod 11, and the screw rod 11 is connected to the threaded barrel 10 by threads.

[0024] A limiting ring 14 is disposed at one end of the movable groove 13 , and a limiting rod 15 is movably connected to the limiting ring 14 .

[0025] In this embodiment, refer to Figure 1 The valve body 18 is oval in shape, and its edges are relatively integrated and smooth. When exhausting smoke, the smoke will not generate a vortex at the ends of the valve body 18 due to mutual collision, so that the smoke can enter the valve body 18 more smoothly, thereby improving the exhaust efficiency of the valve body 18;

[0026] During installation, the worker first pulls out the L-shaped card plate 19, then sleeves the pipe 6 on the outer ring of the mounting frame 1, until the front of the connecting plate 8 fits with the back of the mounting plate 2, pushes the L-shaped card plate 19 back, until the three connecting holes 9 are on the same horizontal line, and then passes one end of the screw rod 11 through the connecting hole 9 and is connected to the threaded barrel 10 by threading, thereby locking the position of the connecting plate 8 between the L-shaped card plate 19 and the mounting plate 2, and completing the installation of the device;

[0027] The threaded barrel 10 wraps the outer ring of the screw 11, so that the screw 11 can complete the connection between the mounting frame 1 and the pipe 6 in a hidden form, avoiding corrosion of the surface of the screw 11 by foreign substances, so as to facilitate the subsequent disassembly and maintenance of the smoke damper, thereby improving the practicality of the device;

[0028] The screw rod 11 itself is not connected to the mounting plate 8, and the mounting plate 8 is mainly limited by the L-shaped clamping plate 19 and the mounting plate 2, so the connection strength is high and it is not easy to loosen.

[0029] The outer wall of the mounting frame 1 is provided with a plug-in frame 3 , the inner wall of the pipe 6 is provided with a slot 7 , the plug-in frame 3 and the slot 7 are of the same size, and the plug-in frame 3 and the slot 7 are movably connected.

[0030] In this embodiment, the bracket 3 is composed of a plurality of rectangular evenly arranged metal rods, and the slot 7 is composed of a plurality of strip-shaped grooves. When the pipe 6 is sleeved on the outer ring of the mounting bracket 1, the bracket 3 is snapped into the inner cavity of the slot 7, thereby ensuring that the connection between the mounting bracket 1 and the pipe 6 will not shake, so as to prevent smoke from seeping out through the gap between the mounting bracket 1 and the pipe 6, thereby improving the sealing of the device.

[0031] A fixing plate 4 is disposed at one end of the valve body 18 , and an exhaust fan 5 is disposed in the inner cavity of the fixing plate 4 .

[0032] In this embodiment, the fixing plate 4 is used for installing the exhaust fan 5. When the device is exhausting smoke, the control center starts the exhaust fan 5. At this time, the exhaust fan 5 can accelerate the flow of air to increase the amount of smoke passing through the valve body 18, thereby further improving the smoke exhaust efficiency of the device.

[0033] The outer ring of the screw rod 11 is provided with a washer 20 , the front surface of the mounting plate 2 is provided with a groove 16 , the groove 16 and the connecting hole 9 are concentric circles, and one end of the screw rod 11 is provided with a hexagonal rotation groove 12 .

[0034] In this embodiment, the washer 20 can prevent the screw 11 from loosening and play a role in strengthening the connection. The washer 20 is a prior art and will not be described in detail here. When one end of the screw 11 is connected to the threaded barrel 10, the other end is in the inner cavity of the groove 16, so that the screw 11 can be completely hidden to prevent foreign matter from entering the connecting hole 9. At the same time, the overall aesthetics of the device can be improved. When disassembling, the screw 11 can be unscrewed through the groove 12.
