Description

Technical Field

[0001] This utility model belongs to the field of ventilation duct technology, and specifically relates to an assembled ventilation duct. Background Technology

[0002] Ventilation ducts are hollow pipes used for ventilation, and they are mostly round or square.

[0003] Currently, a Chinese utility model with announcement number CN218670950U discloses a splicing PP ventilation duct. This utility model disassembles the ventilation duct into multiple splicable parts, which users can transport by stacking these parts separately, reducing the difficulty of transporting the ventilation duct.

[0004] Although this modular ventilation duct can be transported by stacking, it still has some problems in use. For example, the splicing rods and splicing plates of this modular ventilation duct lack a sealing structure. Directly inserting the splicing plates into the slots of the splicing plates results in poor sealing and easily causes air leakage when the airflow is transported in the duct. This leads to air leakage, energy loss, and airflow impact, which also causes noise and vibration. At the same time, this modular ventilation duct lacks a structure that can quickly splice two ducts together. When splicing two ducts together, it is necessary to align the holes and threads. When splicing multiple sections of the modular ventilation duct, deviations are prone to occur, making it difficult to align the holes and threads and slowing down the splicing speed of multiple sections. Utility Model Content

[0005] The purpose of this utility model is to provide an assembled ventilation duct, which has the advantages of good sealing effect and convenient connection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an assembled ventilation duct, including a first flange seat, a second flange seat provided on one side of the first flange seat, a connecting seat provided between the first flange seat and the second flange seat, the number of connecting seats being four, an outer side plate placed between two of the connecting seats, a first pressure plate symmetrically arranged between two of the connecting seats, a second pressure plate symmetrically arranged between two of the connecting seats, a sealing strip embedded in the side of the first pressure plate and the second pressure plate near the outer side plate, a frame fixedly connected to the surface of the second flange seat, and an inclined surface provided on the inner side wall of the frame.

[0007] The above technical solution is adopted as follows: By designing the first and second pressure plates, when the outer plate is placed in the recessed area of ​​the two connecting seats, the first and second pressure plates can fix the outer plate on the connecting seats and support plates, improving the firmness. At the same time, the sealing strips installed on the first and second pressure plates can play a sealing role, improving the sealing performance between the connecting seats and support plates and the outer plate. The outer surface of the second flange seat is designed with a frame, and the inner wall edge of the frame is provided with a slope. When multiple pipe sections are spliced, the first flange seat of the preceding pipe section will enter the frame under the action of the slope on the frame of the following pipe section, so that the first flange seat of the preceding pipe section and the second flange seat of the following pipe section are aligned, which facilitates the subsequent hole and thread alignment and improves the speed of splicing multiple pipe sections.

[0008] The present invention is further configured such that the first flange seat and the second flange seat are both connected to the connecting seat by bolt threads.

[0009] The above technical solution facilitates the fixing of the connecting seat between the first flange seat and the second flange seat.

[0010] The present invention is further configured such that the first pressure plate is threadedly connected to the connecting seat by bolts.

[0011] The above technical solution facilitates the fixing of the first pressure plate onto the connecting seat.

[0012] The present invention is further configured such that a support plate is fixedly connected to the opposite side of the first flange seat and the second flange seat.

[0013] The above technical solution facilitates the support of the outer side panel.

[0014] The present invention is further configured such that the second pressure plate is threadedly connected to the support plate by bolts.

[0015] The above technical solution facilitates pressing the outer side plate onto the support plate.

[0016] The present invention is further configured such that the outer side plate is made of galvanized steel plate.

[0017] The above technical solution is adopted to improve the strength of the outer side panel.

[0018] The present invention is further configured such that the first flange seat, the second flange seat, and the connecting seat are all made of stainless steel.

[0019] The above technical solution improves the corrosion resistance of the first flange seat, the second flange seat, and the connecting seat.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By designing the first and second pressure plates, when the outer plate is placed in the recessed area of ​​the two connecting seats, the first and second pressure plates can fix the outer plate to the connecting seats and the support plate, improving the firmness. At the same time, the sealing strips installed on the first and second pressure plates can play a sealing role, improving the sealing performance between the connecting seats and the support plate and the outer plate.

[0022] 2. This utility model features a frame on the outer surface of the second flange seat, with an inclined surface on the inner wall edge of the frame. When multiple pipe sections are spliced, the first flange seat of the preceding pipe section will enter the frame under the action of the inclined surface on the frame of the following pipe section, aligning the positions of the first flange seat of the preceding pipe section and the second flange seat of the following pipe section. This facilitates subsequent hole and thread alignment and increases the speed of splicing multiple pipe sections. Attached Figure Description
