[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Combine the following Figures 1 to 3 The utility model is described in detail.

[0022] A tunnel air duct support includes a fan 1, one end of the fan 1 is connected to an air duct 2, the bottom of the fan 1 is connected to a support 3, the top of the support 3 is provided with a supporting base 301, the top of the support 3 is provided with a placement base 4 near one end of the top, the middle of the placement base 4 is provided with an engaging groove 402, the middle of the engaging groove 402 is connected to a stabilizing component, the stabilizing component moves and assembles along the engaging groove 402, and the stabilizing component fits the air duct 2 for moving and assembling.

[0023] First, the fan 1 is mounted on the support base 301 of the bracket 3 , and then the air duct 2 is connected to one end of the fan 1 , so that the external air is transported into the tunnel through the air duct 2 .

[0024] Furthermore, the air duct 2 is made of metal material, and the air duct 2 is composed of a plurality of metal tubes spliced ​​together.

[0025] By changing the air duct 2 into a plurality of metal tubes spliced ​​together, the air duct 2 can better withstand the blowing of wind and the erosion of rain.

[0026] Further, the placement base 4 is arranged at the bottom of the air duct 2 extending from the bracket 3, and the placement base 4 also includes a connecting block 401, a slide groove 403 and a transmission rod 404, the connecting block 401 is arranged at one end of the placement base 4, the slide groove 403 is arranged on both sides of the middle of the chimeric slot 402, the transmission rod 404 is arranged at one end of the placement base 4 away from the connecting block 401, and the stabilizing component includes a limiting ring 405, a fixing block 4051 and a through slot 4052, and the limiting ring 405 is connected to the chimeric slot 402 The fixing block 4051 is arranged at one end of the limiting ring 405, and the through slot 4052 is arranged in the middle of the limiting ring 405. The limiting ring 405 is connected with the slide slot 403 through the protrusions on both sides near one end. The fixing block 4051 and the connecting block 401 are both provided with threaded holes that cooperate with each other. The through slot 4052 is penetrated by the transmission rod 404, and the side wall of the transmission rod 404 cooperates with the rack on one side of the inner wall of the through slot 4052. The transmission rod 404 penetrates several placement bases 4 in series.

[0027] When the metal air duct 2 is installed, it will be supported and placed at the bottom by the placement base 4 on the extended part of the bracket 3. After the placement is completed, the transmission rod 404 is rotated by controlling the transmission of the motor. The transmission rod 404 penetrates the placement base 4 and also penetrates the through slot 4052 of the limiting ring 405. The rack on one side of the inner wall of the through slot 4052 engages with the transmission rod 404, so that the transmission rod 404 drives the limiting ring 405 to move along the embedded slot 402 when rotating. At the same time, during the displacement of the limiting ring 405, the protrusion near one end is engaged in the slide groove 403 to move, so that the displacement of the limiting ring 405 is more stable, so that it can form a circle with the placement base 4 to provide annular support for the air duct 2, so that the part of the air duct 2 exposed outside the tunnel will not be shaken and rubbed when it is affected by external force due to the contact and connection with the bracket, resulting in wear. At the same time, the transmission rod 404 penetrates several placement bases 4, so that it can drive several limiting rings 405 to perform surrounding limiting together.

[0028] At the same time, because the limiting ring 405 and the placement base 4 can only be semicircular, and because the slide groove 403 is not set to be through, the last end of the limiting ring 405 will be separated from one end of the placement base 4 by a certain distance. Therefore, the connecting block 401 and the fixing block 4051 can be penetrated by a screw rod to connect the two, so that the limiting ring 405 and the placement base 4 can be connected to a certain extent, making the limiting ring 405 more stable after the displacement is limited.

[0029] The following is a specific implementation process of the utility model. First, the fan 1 is set up on the support base 301 of the bracket 3, and then the air duct 2 is connected to one end of the fan 1. The external air is transported into the tunnel through the air duct 2. The air duct 2 is changed into a plurality of metal tubes spliced ​​together to make the air duct 2 more able to withstand the blowing of wind and the erosion of rain. When the metal air duct 2 is installed, it will be supported and placed at the bottom through the placement base 4 on the extension part of the bracket 3. After the placement is completed, the transmission rod 404 is rotated by controlling the transmission of the motor. The transmission rod 404 penetrates the placement base 4 and also penetrates the through slot 4052 of the limiting ring 405. The rack on one side of the inner wall of 4052 is meshed with the transmission rod 404, so that when the transmission rod 404 rotates, it will drive the limiting ring 405 to move along the embedded groove 402. At the same time, during the displacement of the limiting ring 405, the protrusion close to one end will be embedded in the slide groove 403 to move, so that the displacement of the limiting ring 405 is more stable, so that it can form a circle with the placement base 4 to provide annular support for the air duct 2, so that the part of the air duct 2 exposed outside the tunnel will not cause shaking, friction and wear when it is affected by external force due to contact and connection with the bracket. At the same time, the transmission rod 404 passes through several placement bases 4, so that it can drive several limiting rings 405 to perform surrounding limiting together.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
