Technical Field

[0001] The utility model relates to the technical field of air ducts, in particular to an air duct capable of preventing blockage. Background Art

[0002] In modern industry and daily life, air duct systems are widely used in ventilation, air conditioning, smoke exhaust and other fields. Traditional air ducts often face the problem of blockage during long-term use. With the development of industrial production and the improvement of people's requirements for air quality, impurities such as dust, fibers, and particles in the air ducts are easy to accumulate, resulting in reduced ventilation efficiency of the air ducts and even affecting the normal operation of the entire system. For example, in the ventilation system of a factory, dust generated during the production process may enter the air duct and gradually accumulate; in the air conditioning system, dust and fibers in the air may also block the air duct.

[0003] In order to prevent blockage inside the air duct, a dust screen needs to be installed at the port of the air duct, but the existing dust screen is generally fixed and not convenient to disassemble and clean. In view of this, we need an air duct that can prevent blockage. Utility Model Content

[0004] The purpose of the utility model is to provide an air duct that can prevent blockage, so as to solve the problems raised in the above background technology.

[0006] An elastic plate, wherein the elastic plate is fixedly mounted on an outer wall of the mounting frame;

[0007] A clamping block is fixedly mounted on the outer wall of the elastic plate, and one side of the clamping block is arranged in an arc shape.

A clamping plate is fixedly passed through the interior of the rotating rod, and the clamping plate is arranged in an arc shape.

[0012] Preferably, a groove is provided on the outer wall of the air inlet, and the groove is located on the side of the clamping plate.

[0013] Compared with the prior art, the utility model provides an air duct that can prevent blockage, and has the following beneficial effects:

DETAILED DESCRIPTION

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: an air duct that can prevent blockage, including a body 1, an air inlet 2 is opened on the side wall of the body 1, an air outlet 3 is opened on the side wall of the body 1, a mounting frame 4 is arranged on the side of the air inlet 2, and the mounting frame 4 is installed by pushing the mounting frame 4 to the right, a screen 5 is arranged inside the mounting frame 4, a mounting mechanism 6 is arranged on the mounting frame 4 and the air inlet 2, and a stabilizing mechanism 7 is arranged on the mounting frame 4 and the air inlet 2.

[0022] In this embodiment, an installation mechanism 6 is provided on the installation frame 4 and the air inlet 2. The block 62 in the installation mechanism 6 is engaged with the inside of the slot 63, which facilitates the installation of the screen 5 inside the installation frame 4. At the same time, the sliding of the guide block 64 in the guide slot 65 can prevent the interior from deviating during the installation process. By pushing the elastic plate 61, the block 62 can be driven to move out of the slot 63 to release the limit, thereby facilitating disassembly.

[0023] In this embodiment, a stabilizing mechanism 7 is provided on the mounting frame 4 and the air inlet 2. By moving the clamping plate 73 in the middle of the stabilizing mechanism 7 toward the air inlet 2, the clamping plate 73 can be rotated around the rotating rod 71 and engaged into the inside of the groove 74 to make the installation more stable. At the same time, the elastic force of the torsion spring 72 can enable the rotating rod 71 to drive the clamping plate 73 to rotate and reset, thereby facilitating the disassembly and cleaning of the screen 5 inside the mounting frame 4.

A clamping block 62 is fixedly mounted on the outer wall of the elastic plate 61, which is clamped into the interior of the clamping slot 63 by the clamping block 62, so as to facilitate the installation of the screen 5 inside the mounting frame 4. One side of the clamping block 62 is arranged in an arc shape, and the arc surface of the clamping block 62 is squeezed by the air inlet 2, so that the clamping block 62 can drive the elastic plate 61 to deform so that the limit is released, which is convenient for installation. A clamping slot 63 is provided on the side wall of the air inlet 2, and the clamping slot 63 is located on the side of the clamping block 62. A guide block 64 is fixedly mounted on the outer wall of the air inlet 2, and a guide groove 65 is provided on the inner wall of the mounting frame 4, and the guide groove 65 is located on the side of the guide block 64.

When the locking cam 72 is in the state of being firmly fixed on the locking cam 74, the locking cam 73 is in the state of being firmly fixed on the locking cam 74.

[0026] In this embodiment, the installation is first performed by pushing the installation frame 4 to the right, and the block 62 on the outer wall of the elastic plate 61 is driven to move to the right by the installation frame 4, so that the arc surface of the block 62 is squeezed by the air inlet 2, so that the block 62 drives the elastic plate 61 to deform so that the limit is released, and then the block 62 is driven to continue to move to the right by the elastic plate 61, and finally the block 62 is connected to the inside of the card slot 63, and the installation of the screen 5 inside the installation frame 4 is completed. During the installation, the guide block 64 slides inside the guide slot 65 to prevent the interior from deviating during the installation process. At the same time, the installation frame 4 is provided with The locking cam 73 is pressed against the locking cam 74 to lock the locking cam 76. The locking cam 73 is pressed against the locking cam 76 and the locking cam 76 is in a state of being moved downwardly.
