Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment installation technology, and specifically to a duct installation and fixing device. Background Technology

[0002] In building construction, duct installation is a common step, with square ducts being the most prevalent. Because ducts need to better adapt to building space layouts, especially in situations with height and size limitations, specific requirements arise. This necessitates localized design modifications to the ducts, such as right angles, rounded corners, U-shapes, L-shapes, etc. During installation, instability often occurs due to varying site conditions. While simple brackets are typically used for fixing, complex layouts, particularly irregular designs, can cause significant construction difficulties. Incompatible brackets can lead to problems like severe duct vibration or even detachment later on. Furthermore, the stability requirements of irregular designs may necessitate the installation of multiple brackets in certain areas, resulting in wasted materials and labor. Summary of the Invention

[0003] In view of the technical defects of traditional duct installation methods, this utility model provides a duct installation and fixing device, including a placement plate, a lifting plate, a fixing base, support screws, a drive screw, and a lateral limiting component. The placement plate is located below, and the lifting plate is located above, arranged in parallel. Two through holes are provided near both ends of the placement plate and the lifting plate. There are two support screws and two drive screws, each forming a set. The two sets of screws pass through the two through holes at both ends of the placement plate and the lifting plate, respectively. Each support screw is connected to the placement plate and the lifting plate through its through hole using a built-in nut with internal threads. The free end near the placement plate is secured with a nut to prevent the placement plate from detaching, while the other free end is fixedly connected to the fixed base. The drive screw also passes through the placement plate and the lifting plate. A bearing is built into the through hole of the placement plate to connect the drive screw to the placement plate. The lifting plate is connected to the drive screw via a nut with internal threads built into the through hole. The end of the drive screw near the placement plate is connected to the turntable, and the end near the lifting plate is connected to it via a bearing set on the fixed base. The lifting plate is split into two parts near the middle, and the two parts can be raised and lowered separately. The lateral limiting component is located below the two parts of the lifting plate, between the two sets of screws.

[0004] Because the two sets of screws and two fastening plates form a liftable fastening frame, it can be easily adapted to any size or irregular shape of the duct, and installation and adjustment are very convenient. This increases the duct's strength and stability, reduces labor and material waste, and avoids delays in construction due to mismatched fastening frames.

[0005] Furthermore, the placement plate is provided with a shock-absorbing and anti-slip pad layer.

[0006] The addition of anti-vibration and anti-slip pads further enhances the stability of the duct during operation and avoids noise caused by slight vibrations of the duct.

[0007] Furthermore, the connection between the two parts of the lifting plate is a concave-convex contact surface.

[0008] The concave-convex cross-section design increases the friction surface between the two lifting plates, effectively mitigating vibration.

[0009] Furthermore, the lateral limiting component is connected to the lifting plate via a fixed plate fixedly connected below the lifting plate.

[0010] The connection between the lateral limiting component and the lifting plate is more secure through the fixing plate, and the lateral fixation of the air duct is also more effective.

[0011] Furthermore, the lateral limiting component includes a fixed block, a telescopic arm, and a limiting roller. The fixed block and the fixed plate are fixedly connected. One end of the telescopic arm is connected to the fixed block through a "U"-shaped connecting frame, and the other end is connected to the limiting roller shaft.

[0012] The structure of the lateral limiting component forms its elastic limiting capability, which dampens and counteracts the lateral oscillation of the duct.

[0013] Furthermore, the telescopic arm includes an outer arm and an inner arm, which are fitted together. The outer arm has small holes through which bolts pass, and the inner arm has grooves whose position and size correspond to the small holes on the outer arm. The two are fixed together by bolts.

[0014] The segmented design of the telescopic boom can accommodate ducts of different sizes and provide varying levels of vibration resistance.

[0015] Furthermore, the outer surface of the limiting roller is provided with an elastic anti-slip layer.

[0016] The elastic anti-slip layer on the outer surface of the limit roller strengthens its resistance to vibration. Attached Figure Description

[0023] To provide a clearer description of this utility model, the following description is provided in conjunction with the accompanying drawings.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, a duct installation and fixing device includes a placement plate 1, a lifting plate 2, a fixing base 3, a support screw 4, a drive screw 5, and a lateral limiting component 6. The placement plate 1 is below, and the lifting plate 2 is above, arranged in parallel. Two through holes are provided near each end of both the placement plate 1 and the lifting plate 2. There are two support screws 4 and two drive screws 5, each forming a set. The two sets of screws pass through the two through holes at both ends of the placement plate 1 and the lifting plate 2, respectively. Each support screw 4 is connected to the placement plate 1 and the lifting plate 2 with a built-in nut with internal threads in the through hole it passes through. The free end of the support screw 4 near the placement plate 1 is secured with a nut 7. The plate is fixed to prevent it from coming off, and the other free end is fixedly connected to the fixed base 3. The drive screw 5 also passes through the plate 1 and the lifting plate 2. The bearing 8 built into the through hole of the plate 1 connects the drive screw 5 to the plate 1. The lifting plate 2 is connected to the drive screw 5 through the internally threaded nut built into the through hole. The end of the drive screw 5 near the plate 1 is connected to the turntable 9, and the end near the lifting plate 1 is connected to it through the bearing 10 set on the fixed base 3. The lifting plate 2 is split near the middle position, and the two parts can be lifted and lowered separately. The lateral limiting component 6 is set below the two parts of the lifting plate 2, between the two sets of screws.

[0025] Example 2: Based on the above example, the placement plate 1 is provided with a shockproof and anti-slip pad layer 11.

[0026] Example 3: Based on Example 1, the connection between the two parts of the lifting plate 2 is a concave-convex contact surface 12.

[0027] Example 4: Based on any one of the above three examples, the lateral limiting component 6 is connected to the lifting plate via a fixed plate 13 fixedly connected below the lifting plate 2.

[0028] Example 5: Based on Example 4, the lateral limiting component 6 includes a fixed block 14, a telescopic arm 15, and a limiting roller 16. The fixed block 14 and the fixed plate 13 are fixedly connected. One end of the telescopic arm 15 is connected to the fixed block 14 through a "U"-shaped connecting frame 17, and the other end is connected to the shaft of the limiting roller 16.

[0029] Example 6: Based on Example 5, the telescopic arm 15 includes an outer arm 18 and an inner arm 19, which are fitted together. The outer arm 18 is provided with a small hole 20 through which bolts pass, and the inner arm 19 is provided with a groove 21 whose position and size correspond to the small hole 20 on the outer arm 18. The two are fixed by bolts.

[0030] Example 7: Based on Example 6, the outer surface of the limiting roller 16 is provided with an elastic anti-slip layer.

[0031] It should be noted that this specification describes some embodiments, and any technical improvements or substitutions of some components by those skilled in the art based on the prior art are within the protection scope of this utility model.

[0032] In actual construction, the fixing seat is fixedly installed at the pre-determined installation position. Then, the air duct passes through the space formed by the placement plate 1, the lifting plate 2, and the two lateral limiting components 6. By rotating the nut at the lower end of the support screw and the turntable at the lower end of the drive screw, the two parts of the lifting plate 2 can be raised and lowered separately, fixing the air duct in the vertical dimension to prevent it from loosening due to vibration in this dimension. Loosen the bolts at the connection between the fixing block 14 of the lateral limiting component 6 and the telescopic arm 15, and the bolts between the inner and outer arms of the telescopic arm 15. Adjust the opening of the telescopic arm 15 and the lateral force of the limiting roller 16 on the air duct, and then tighten the corresponding bolts to complete the lateral limiting of the air duct. Following the above steps, the air duct receives the force of the fixing device of this utility model in both the longitudinal and lateral dimensions, which can make the air duct less displaced due to vibration. Furthermore, the elastic anti-slip layer on the outer surface of the limiting roller 16 and the shock-absorbing and anti-slip pad layer 11 on the placement plate 1 can reduce the vibration amplitude of the air duct and also reduce the noise caused by vibration.
