[0043] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a smoke exhaust pipe fixing device 100, which is mainly used to fix the smoke exhaust pipe 200 so that the smoke exhaust pipe 200 can be easily moved and transported. The smoke exhaust pipe fixing device 100 includes a mounting frame 110, a first fixing assembly 120 and a second fixing assembly 130.

[0044] The mounting frame 110 is formed with a receiving space 112 .

[0045] like Figure 1 As shown, the smoke exhaust pipe 200 is generally cylindrical in shape, and the mounting frame 110 is generally rectangular in shape, so that the smoke exhaust pipe 200 is entirely installed in the mounting frame 110 , forming a first level of fixation for the smoke exhaust pipe 200 .

[0046] In this embodiment, the smoke exhaust pipe 200 includes a muffler 210, an expansion joint 220, a smoke three-way valve 230 and a manifold 240 which are connected in sequence.

[0047] The first fixing assembly 120 is used to fix the muffler 210 , and the second fixing assembly 130 is used to fix the flue gas three-way valve 230 .

[0048] like Figure 1 As shown, the outer surface of the muffler 210 is cylindrical, and the supporting surface of the first fixing component 120 is required to fit the arc-shaped outer surface of the muffler 210 to prevent the muffler 210 from moving.

[0049] The first fixing assembly 120 is located in the accommodating space 112 to fix the muffler 210 in the mounting frame 110 .

[0050] Specifically, the first fixing assembly 120 includes a first connecting seat 121 and two diagonal support seats 122. The first connecting seat 121 is connected to the mounting frame 110. The two diagonal support seats 122 are arranged on one side of the first connecting seat 121 close to the accommodating space 112. The diagonal support seats 122 are formed with inclined surfaces 1221. The two inclined surfaces 1221 of the two diagonal support seats 122 are opposite to each other. By making the two diagonal support seats 122 provide two oblique supporting forces to the muffler 210, the muffler 210 is not easy to roll, and the two diagonal support seats 122 can be stably supported under the muffler 210. The diagonal support seats 122 cooperate with the mounting frame 110 to reduce the vibration amplitude of the muffler 210 during transportation and prevent the first fixing assembly 120 from deforming.

[0051] Please continue reading Figure 1 In some embodiments, a limiting member 111 is still provided on the mounting frame 110 , and the limiting member 111 and the two diagonal support seats 122 are relatively spaced apart along the third direction D3 .

[0052] The limiter 111 is fixed above the muffler 210 and has an arc-shaped limiter surface. The limiter 111 cooperates with the first fixing assembly 120 to fix the muffler 210 to prevent the muffler 210 from rotating or vibrating during the moving and transporting process, thereby forming a second level of fixation for the smoke exhaust pipe 200.

[0053] The second fixing assembly 130 is connected to the mounting frame 110 and is located in the accommodation space. The second fixing assembly 130 and the first fixing assembly 120 are spaced apart along the first direction D1, and the second fixing assembly 130 forms a fixing frame 133. By restricting the three-way smoke valve 230 in the fixing frame 133, the three-way smoke valve 230 can be prevented from moving during transportation, thereby forming a third level of fixing for the smoke exhaust pipe 200.

[0054] By forming a triple fixation for the smoke exhaust pipe 200, the first fixing component 120 or the second fixing component 130 can be prevented from moving or deforming during transportation, so that no shear force can be generated between the muffler 210 and the smoke three-way valve 230, and the two always maintain a firm connection to avoid damage to the smoke exhaust pipe 200.

[0055] It can be understood that the smoke exhaust pipe 200 has multiple specifications and models, and the muffler 210 has different sizes.

[0056] In response to the above problems, Figures 2 to 4As shown, in some embodiments, the diagonal support seat 122 is movably connected to the first connecting seat 121, so as to change the distance between the two inclined surfaces 1221 to accommodate mufflers 210 of different sizes.

[0057] In this embodiment, the diagonal support seat 122 includes a first base plate 1222 and a first adjusting bolt 1223. The first base plate 1222 is connected to the first connecting seat 121. An oblong hole 12221 is provided on the first base plate 1222. A corresponding connecting hole 12111 is provided on the first connecting seat 121. The first adjusting bolt 1223 is passed through the oblong hole 12221 and the connecting hole 12111.

[0058] Thus, during the adjustment stage, the first adjusting bolt 1223 can be loosened to change the position of the first adjusting bolt 1223 in the oblong hole 12221, so that the diagonal support seat 122 can be moved left and right on the first connecting seat 121, thereby changing the distance between the two inclined surfaces 1221. When the distance between the two inclined surfaces 1221 is determined, the first adjusting bolt 1223 can be tightened to fix the diagonal support seat 122 on the first connecting seat 121.

[0059] like Figures 2 to 4 As shown, the number of the oblong holes 12221 can be set according to the needs. In this embodiment, four oblong holes 12221 are provided on the first bottom plate 1222 of each diagonal support seat 122. In other embodiments, the number of the oblong holes 12221 can also be one, two, three, etc. The number of the first adjusting bolts 1223 is the same as the number of the oblong holes 12221, and each oblong hole 12221 is provided with a first adjusting bolt 1223.

[0060] In this embodiment, by providing four first adjusting bolts 1223 , the bonding force between the diagonal support seat 122 and the first connecting seat 121 can be enhanced to prevent the diagonal support seat 122 from moving during the mobile transportation process and thus damaging the smoke exhaust pipe 200 .

[0061] In some embodiments, the diagonal support seat 122 further includes an inclined plate 1224 , a first vertical plate 1225 , a second vertical plate 1226 and a third vertical plate 1227 .

[0062] The inclined surface 1221 is disposed on the inclined plate 1224. In this embodiment, the inclined surface 1221 is a plane, which is conducive to the inclined surface 1221 being applicable to mufflers 210 of different sizes. In other embodiments, the inclined surface 1221 can be set as a curved surface.

[0063] In some embodiments, a gasket 1228 is further provided on the inclined plate 1224 to increase the friction between the muffler 210 and the inclined plate 1224, making it difficult to move, and also to form a flexible contact between the muffler 210 and the inclined plate 1224.

[0064] The first vertical plate 1225 , the second vertical plate 1226 and the third vertical plate 1227 are arranged on the first bottom plate 1222 in parallel along the second direction D2 , and are respectively connected to one side of the inclined plate 1224 away from the inclined surface 1221 .

[0065] In the third direction D3, the heights of the first vertical plate 1225, the second vertical plate 1226, and the third vertical plate 1227 gradually increase, restricting the muffler 210 within the two diagonal support seats 122 to prevent the muffler 210 from being fixed. In some embodiments, only the first vertical plate 1225 and the third vertical plate 1227 may be provided. Adding the second vertical plate 1226 can increase the support force on the inclined plate 1224, strengthen the rigidity of the overall structure of the diagonal support seat 122, and make the diagonal support seat 122 less likely to deform.

[0066] It should be noted that the mounting frame 110 is roughly in the shape of a cube. Figure 1 As shown, the first direction D1 is the length direction of the mounting frame 110, the second direction D2 is the width direction of the mounting frame 110, and the third direction D3 is the height direction of the mounting frame 110. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. In other embodiments, the directions indicated by the first direction D1, the second direction D2, and the third direction D3 can be adjusted according to actual needs.

[0067] like Figure 2 As shown, in some embodiments, the first fixing assembly 120 includes an adjusting member 123 , and the two diagonal support seats 122 are movably connected to the adjusting member 123 respectively to adjust the distance between the two diagonal support seats 122 .

[0068] In some embodiments, the adjustment member 123 includes a screw rod 1231 and a second adjustment bolt 1232 . A through hole 12251 is opened on the first vertical plate 1225 and the second vertical plate 1226 . The screw rod 1231 passes through the through hole 12251 . The second adjustment bolt 1232 is disposed on a side of the second vertical plate 1226 away from the first vertical plate 1225 .

[0069] The threaded rod is arranged along the second direction D2, and two diagonal support seats 122 are respectively arranged at both ends of the threaded rod. When the distance between the two diagonal support seats 122 needs to be adjusted, the first adjustment bolt 1223 and the second adjustment bolt 1232 are both loosened to move each diagonal support seat 122 to an appropriate position. When the position of the diagonal support seat 122 is determined, the first adjustment bolt 1223 and the second adjustment bolt 1232 are respectively tightened to relatively fix the positions of the two diagonal support seats 122.

[0070] It can be understood that in some embodiments, the adjustment member 123 may not be used. Adding the adjustment member 123 can enhance the bonding force between the two diagonal support seats 122, strengthen the rigidity of the first fixing component 120, make it less likely to deform, and form a stable support for the muffler 210.

[0071] In some embodiments, the first connecting base 121 includes a second bottom plate 1211 and a clamping portion 1212 .

[0072] The clamping portion 1212 is disposed on a side of the second bottom plate 1211 away from the diagonal support seat 122 , and the mounting frame 110 is correspondingly provided with a clamping slot (not shown) to enable the clamping portion 1212 to be clamped with the mounting frame 110 , so that the first connecting seat 121 and the mounting frame 110 can be easily disassembled and assembled.

[0073] like Figure 2 and Figure 3 As shown, there are multiple clamping parts 1212, and the multiple clamping parts 1212 are arranged at intervals. By providing multiple clamping parts 1212, the bonding force between the first connecting seat 121 and the mounting frame 110 is increased, so that the connection between the first fixing assembly 120 and the mounting frame 110 is more stable.

[0074] like Figure 1 As shown, the flue gas three-way valve 230 is roughly in the shape of a cube, and a frame structure can be provided to fix the flue gas three-way valve 230 .

[0075] like Figure 5 As shown, in some embodiments, the second fixing assembly 130 includes a second connecting seat 131 and a fixing frame 132 .

[0076] The second connecting seat 131 is connected to the mounting frame 110, and the fixing frame 132 is connected to the side of the second connecting seat 131 facing the accommodating space 112 to form a fixing frame 133. The fixing frame 133 is rectangular, and the flue gas three-way valve 230 is inserted into the fixing frame 133. The fixing frame 133 is sleeved on the outside of the flue gas three-way valve 230 and connected to the mounting frame 110 to fix it.

[0077] It can be understood that the smoke exhaust pipe 200 has multiple specifications and models, and the smoke three-way valve 230 has different sizes.

[0078] To address the above problem, in some embodiments, the fixing frame 132 includes a limiting rod 1321 and two vertical rods 1322 that are spaced apart.

[0079] The limiting rod 1321 and the second connecting seat 131 are arranged in parallel and spaced apart along the third direction D3, the vertical rod 1322 is fixedly connected to the second connecting seat 131, and the limiting rod 1321 and the vertical rod 1322 are movably connected.

[0080] For example, Figure 5As shown, two holes are provided at both ends of the limit rod 1321, and one limit rod 1321 is correspondingly inserted into one hole. The two vertical rods 1322 are threaded rods, and nuts 1323 are provided on the vertical rods 1322 to adjust the distance between the limit rod 1321 and the second connecting seat 131, so that the fixing frame 133 can fix the flue gas three-way valve 230 of different sizes.

[0081] In some embodiments, in the third direction D3, the second connecting seat 131 has the same height as the first connecting seat 121, so that the central axes of the muffler 210 and the flue gas three-way valve 230 can coincide with each other, preventing shear force from being generated between the muffler 210 and the flue gas three-way valve 230.

[0082] In some embodiments, the first connecting seat 121 and the second connecting seat 131 are fixed by welding, the first connecting seat 121 and the mounting frame 110 are clamped by the clamping portion 1212 and the clamping groove, the second connecting seat 131 and the mounting frame 110 are threadedly connected, and multiple connection points of the mounting frame 110 are threadedly connected, so that the smoke exhaust pipe fixing device 100 as a whole can be disassembled and assembled, reducing the transportation cost of the smoke exhaust pipe fixing device 100, and the smoke exhaust pipe 200 can be fixed and assembled on-site in the factory, improving efficiency, and reducing the application site restrictions of the smoke exhaust pipe fixing device 100.
