Description

Technical Field

[0001] This utility model relates to the field of ventilation duct technology, and in particular to a detachable ventilation duct. Background Technology

[0002] Ventilation ducts are metal or non-metal pipes used in ventilation and air conditioning systems for industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases.

[0003] Existing ventilation ducts are made by connecting several ducts end to end. When connecting two duct sections, the installation speed is often slow because the mounting holes are not aligned. After installation, a relatively sealed space is formed inside the ventilation duct during subsequent use, and air flows inside. However, this sealed structure makes maintenance very troublesome during subsequent use. For example, if a rat enters the ventilation duct and needs to be exterminated, the extermination operation can only be carried out at the outlet and inlet of the ventilation duct, which has limited effect. Cleaning the inside of the ventilation duct is also very difficult. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a detachable ventilation duct.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable ventilation duct includes: a duct body, a first connecting plate, and a second connecting plate. The first connecting plate and the second connecting plate are respectively installed on the left and right walls of the duct body. A circular hole is formed on the lower wall of the duct body. Two sets of sealing structures are installed on the lower wall of the duct body. A lifting structure is installed on the lower wall of the duct body. The sealing structure includes: a sealing protrusion, a sealing cover, and a universal ring. The sealing protrusion is installed on the lower wall of the duct body. The universal ring is installed in the circular hole of the duct body. The sealing cover is installed on the outside of the sealing protrusion by bolts. The inner wall of the universal ring is threaded.

[0007] The present invention is further configured with two sets of the hoisting structure, including: a hoisting support base and a hoisting bracket; the hoisting support base is installed on the lower wall of the pipe body, and the hoisting bracket is connected to the hoisting support base by bolts.

[0008] The present invention is further configured such that an air pump is installed inside the general ring via threads.

[0009] The present invention is further configured such that a ventilation branch pipe is installed inside the general ring by means of threads.

[0010] The present invention is further provided with four mounting hooks on the side wall of the first connecting plate.

[0011] The present invention is further provided that the side wall of the second connecting plate has four mounting holes.

[0012] The present invention is further provided that the outer edge of the sealing cover has a flange.

[0013] The beneficial effects of this utility model are as follows: By adding installation hooks and installation holes to the ventilation ducts, the hooks and installation holes of the two ventilation ducts are connected during installation, and the threaded holes of the two ducts can be aligned, allowing the operator to install bolts. This improves the installation speed of the ventilation ducts to a certain extent. In addition, this utility model makes the lower end of the ventilation duct detachable, which facilitates the cleaning and maintenance of the ventilation ducts and makes it easier for operators to use and manage the ventilation ducts.

Therefore, they should not be construed as limitations on this patent.

[0022] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0023] Reference Figure 1-4 A detachable ventilation duct includes: a duct body 1, a first connecting plate 2, and a second connecting plate 3. The first connecting plate 2 and the second connecting plate 3 are respectively installed on the left and right walls of the duct body 1. A circular hole is opened on the lower wall of the duct body 1. Two sets of sealing structures are installed on the lower wall of the duct body 1. A hoisting structure is installed on the lower wall of the duct body 1. The sealing structure includes: a sealing protrusion 4, a sealing cover 5, and a universal ring 6. The sealing protrusion 4 is installed on the lower wall of the duct body 1. The universal ring 6 is installed in the circular hole of the duct body 1. The sealing cover 5 is installed on the outside of the sealing protrusion 4 by bolts. The inner wall of the universal ring 6 is threaded. The side wall of the first connecting plate 2 is provided with four mounting hooks 11. The side wall of the second connecting plate 3 is provided with four mounting holes 12. The outer edge of the sealing cover 5 is provided with a flange.

[0024] Specifically, the two sets of hoisting structures include: hoisting support base 7 and hoisting bracket 8; the hoisting support base 7 is installed on the lower wall of the pipe body 1, and the hoisting bracket 8 is connected to the hoisting support base 7 by bolts.

[0025] As a preferred option, the air pump 9 is further installed inside the general ring 6 via threads.

[0026] As a preferred option, the general ring 6 is further equipped with a ventilation branch pipe 10 installed inside by threads.

[0027] Working principle: When installing this utility model, firstly, the hoisting bracket 8 is installed on the indoor ceiling. Then, the operator connects the hoisting support 7 of the pipe body 1 to the hoisting bracket 8 using bolts. Next, the operator connects the second pipe body 1 to the first pipe body 1, so that the four mounting hooks 11 of the first connecting plate 2 of the second pipe body 1 are hung in the mounting holes 12 of the second connecting plate 3 of the first pipe body 1. Then, the first connecting plate 2 and the second connecting plate 3 are fastened together with bolts. Finally, the hoisting support 7 of the second pipe body 1 is connected to the hoisting bracket 8 with bolts. At this point, the installation of this utility model is completed.

[0028] When using this utility model, if it is necessary to inspect the inside of the pipe body 1, the operator can remove the sealing cap 5 from the sealing protrusion 4 and observe the inside of the pipe body 1 through the universal ring 6. If it is necessary to temporarily change the ventilation system and add a ventilation branch line, the ventilation branch line pipe 10 can be directly installed inside the universal ring 6 through threads. If the air pressure difference of the ventilation system inside the pipe body 1 is insufficient, resulting in insufficient ventilation capacity, the operator can connect the air port of the air pump 9 to the inner wall of the universal ring 6 through threads, and then connect the air pump 9 to electricity. The air pump 9 will start to increase the air flow rate inside the pipe body 1 and increase the ventilation efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
