Description

Technical Field

[0001] The utility model relates to the technical field related to range hoods, in particular to an air duct installation structure. Background Art

[0002] When conducting a working noise and smoke exhaust resistance simulation test on a range hood, it is necessary to connect the exhaust pipe of the range hood with a fixed air duct for a simulation test. One end of the fixed air duct is connected to the exhaust pipe of the range hood, and the other end passes through the exhaust hole in the wall and is fixed to the wall with tape.

[0003] However, during the simulation test, the exhaust pipe needs to be frequently disassembled and assembled, which may easily cause the fixed air duct to loosen. On the one hand, the frequency of the range hood working noise test is very high, and the loosened fixed air duct may produce abnormal noise and affect the test results. On the other hand, the fixed air duct may also cause wear due to looseness. Utility Model Content

[0004] Based on this, it is necessary to provide a more reliable fixed air duct installation structure to address the problem that the current fixed air duct is prone to loosening during the working noise and smoke exhaust resistance simulation test.

[0005] The present application provides an air duct installation structure for fixing a fixed air duct on a wall.

[0006] It comprises a base plate fixed relative to the wall surface, and the base plate is provided with through holes corresponding to the exhaust holes in the wall surface;

[0007] A plurality of fixing members are fixedly disposed at intervals around the through hole on one side of the substrate away from the wall surface, and the inner surfaces of the fixing members are arc-shaped and flush with the inner wall of the through hole;

[0008] An adjustment structure is provided between two adjacent fixing members, and the adjustment structure can adjust the distance between the proximal ends of the two adjacent fixing members to clamp the fixed air duct.

[0009] In one embodiment, the fixing member is in the shape of a plate.

[0010] In one embodiment, the fixing member is provided with fixing flanges at both ends along the circumferential direction, and the fixing flanges extend outward along the radial direction;

[0011] The adjustment structure includes a first bolt and a first nut. The first bolt passes through two fixing flanges near the ends of two adjacent fixing members. The first nut is threadedly connected to the first bolt.

[0012] In one embodiment, the fixing members on the substrate are of equal length and are arranged at equal intervals.

[0013] In one of the embodiments, two fixing members are fixed on the substrate.

[0014] In one of the embodiments, a limiting ring is fixedly provided on one side of the base plate close to the wall surface, and the outer peripheral surface of the limiting ring is in contact with the inner wall of the exhaust hole.

[0015] In one embodiment, the inner surface of the fixing member, the inner wall of the through hole and the inner circumference of the limiting ring are flush.

[0016] In one of the embodiments, the air duct installation structure includes two substrates located on both sides of the wall and a plurality of clamping structures arranged along the circumferential direction of the exhaust hole, and the clamping structures can clamp and fix the two substrates.

[0017] In one embodiment, each set of the clamping structure includes a second bolt and a second nut, the second bolt passes through the two substrates and the wall, and the second nut is threadedly connected to the second bolt.

[0018] In one embodiment, the substrate is fixed to the wall.

[0031] Please combine Figure 1 , Figure 2 as well as Figure 3 As shown, the present application provides an air duct installation structure for fixing a fixed air duct 100 to a wall 200, comprising a base plate 10 fixed relative to the wall 200, the base plate 10 being provided with a through hole 11 corresponding to an exhaust hole 210 in the wall 200; a plurality of fixing members 20 are fixedly arranged around the through hole 11 at intervals on a side of the base plate 10 away from the wall 200, the inner surface of the fixing member 20 is arc-shaped and flush with the inner wall of the through hole 11; an adjustment structure 30 is arranged between two adjacent fixing members 20, and the adjustment structure 30 can adjust the distance between the near ends of two adjacent fixing members 20 to clamp the fixed air duct 100.

[0032] In the present application, the fixed air duct 100 passes through the through hole 11 and the exhaust hole 210, and the adjustment structure 30 can adjust the distance between the fixing parts 20 to clamp the fixed air duct 100 through the inner surface of the fixing part 20, thereby completing the fixation between the fixed air duct 100 and the air duct mounting structure. Since the base plate 10 is fixed relative to the wall 200, the air duct mounting structure is added between the fixed air duct 100 and the wall 200, so that the fixed air duct 100 can be reliably fixed to the wall 200, thereby avoiding the loosening of the fixed air duct 100 due to frequent loading and unloading of the range hood exhaust pipe.

[0033] Please combine Figure 1 as well as Figure 2 As shown, in some embodiments, the fixing member 20 is plate-shaped.

[0034] The adjusting structure 30 drives two adjacent fixing members 20 to deform to change the spacing, thereby clamping the fixed air duct 100 through the inner surface of the fixing member 20; it is not difficult to understand that when the fixing member 20 is an arc-shaped plate structure, the fixing member 20 is easily deformed by the adjusting structure 30, which facilitates the installation of the fixed air duct 100.

[0035] Please combine Figure 1 as well as Figure 3 As shown, in some embodiments, fixing flanges 21 are respectively fixed at both ends of the fixing member 20 in the circumferential direction, and the fixing flanges 21 extend outward in the radial direction;

[0036] The adjustment structure 30 includes a first bolt 31 and a first nut 32 . The first bolt 31 passes through two fixing flanges 21 near the ends of two adjacent fixing members 20 . The first nut 32 is threadedly connected to the first bolt 31 .

[0037] The threaded connection between the first nut 32 and the first bolt 31 can drive the two fixing members 20 to undergo elastic deformation, so that the two fixing flanges 21 are brought closer to each other and clamp the fixed air duct 100 inside.

[0038] In some embodiments, the first bolt 31 can be a screw with a head at one end, which cooperates with a first nut 32 to clamp and fix the fixing flange 21; the first bolt 31 can also be a single screw, which cooperates with two first nuts 32 to fix the angle of the fixing flange 21.

[0039] Please refer to Figure 1 As shown, in some embodiments, the fixing members 20 on the base plate 10 are of equal length and are arranged at equal intervals, so as to ensure that the fixed air duct 100 is evenly stressed and securely fixed.

[0040] Preferably, two fixing members 20 are fixed on the substrate 10 .

[0041] It should be noted that when conducting working noise and smoke exhaust resistance simulation tests on different range hoods, different fixed air ducts 100 need to be replaced. Frequent loading and unloading of the fixed air ducts 100 may cause greater wear on the inner wall of the exhaust hole 210, thereby affecting the test results.

[0042] In this regard, please combine Figure 1 , Figure 2 as well as Figure 4 As shown, in some embodiments, a limiting ring 40 is fixedly provided on one side of the substrate 10 close to the wall 200 , and the outer peripheral surface of the limiting ring 40 is in contact with the inner wall of the exhaust hole 210 .

[0043] The air duct installation structure of the present application is always fixed relative to the wall 200. When replacing a different fixed air duct 100, the limiting ring 40 is located between the fixed air duct 100 and the inner wall of the exhaust hole 210. This can prevent the fixed air duct 100 from rubbing against the inner wall of the exhaust hole 210, causing the exhaust hole 210 to wear and become larger, thereby protecting the exhaust hole 210.

[0044] Please refer to Figure 2 As shown, in some embodiments, the inner surface of the fixing member 20, the inner wall of the through hole 11 and the inner circumference of the limiting ring 40 are flush; this facilitates the insertion and extraction of the fixed air duct 100, simplifies its loading and unloading difficulty, and reduces the possibility of wear of the fixed air duct 100 during loading and unloading.

[0045] Please combine Figure 3 to Figure 4 As shown, in some embodiments, the air duct installation structure includes two substrates 10 located on both sides of the wall 200 and a plurality of clamping structures 50 arranged along the circumferential direction of the exhaust hole 210 , and the clamping structures 50 can clamp and fix the two substrates 10 .

[0046] Please combine Figure 3 to Figure 4 As shown, in some embodiments, each set of clamping structures 50 includes a second bolt 51 and a second nut 52 , the second bolt 51 passes through the two substrates 10 and the wall 200 , and the second nut 52 is threadedly connected to the second bolt 51 .

[0047] In some embodiments, the second bolt 51 can be a screw with a head at one end, which cooperates with a second nut 52 to clamp and fix the substrate 10; the second bolt 51 can also be a single screw, which cooperates with two second nuts 52 to fix the angle of the substrate 10.

[0048] In some other embodiments, the clamping structure 50 may also adopt other fixing structures such as snap-on, as long as the wall 200 can be fixed by clamping the two substrates 10, and the present application does not make any further limitations here.

[0049] In some embodiments, the substrate 10 is fixed to the wall 200; for example, the substrate 10 is fixed to the wall 200 by expansion bolts, etc., which are not listed one by one in the present application.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
