DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, an adjustable duct for building ventilation includes a base 1, a cover 2 is provided on the base 1, a groove 3 is provided on one side of the base 1, two first slide grooves 4 are provided on the outer wall of the base 1 close to the groove 3, a positioning mechanism 5 is provided in the first slide groove 4, two second slide grooves 6 are provided between the two first slide grooves 4, a slider 7 is provided in the second slide groove 6, a third slide groove 8 is provided on the slider 7, a sealing layer 9 is provided on the inner wall surface of the groove 3, and a plurality of slots 10 are provided on the inner wall of the second slide groove 6 close to the first slide groove 4.

[0024] like Figure 3 and Figure 4 As shown, in another embodiment of the utility model, the positioning mechanism 5 includes a mechanism base 501, a plurality of guide sliders 502 are arranged on the mechanism base 501, a plurality of push friction patterns 503 are arranged on one side of the outer wall of the mechanism base 501, and a plurality of positioning plugs 504 are arranged on one side of the mechanism base 501;

[0025] A sliding block 505 is slidably arranged in the slider 7, and a plurality of guide slots 506 and a push block 507 are arranged on the sliding block 505. A positioning slot 508 is arranged on the side of the sliding block 505 close to the first slot 4. When the diameter of the pipeline needs to be adjusted, the friction pattern 503 is first pushed to move the mechanism base 501 upward along the trajectory of the first slot 4 for a distance, so that the positioning block 504 leaves the positioning slot 508, thereby releasing the fixing of the sliding block 505, and then the sliding block 505 is moved away from the mechanism base 501 by the push block 507, and the moving direction of the sliding block 505 is adjusted by the guide slot 506. After fixing, the sliding block 505 is then moved out of the slot 10, and the cover 2 can be moved in the groove 3, so that the diameter of the pipe can be adjusted by moving the position of the cover 2 in the groove 3. After the adjustment is completed, a part of the sliding block 505 is passed through the slot 10 and into the first slide groove 4 by the push block 507, and then the mechanism base 501 is moved downward along the trajectory of the first slide groove 4 for a distance by pushing the friction pattern 503, so that the positioning block 504 is inserted into the positioning slot 508, thereby fixing the sliding block 505, and then fixing the position of the slider 7 by the sliding block 505, and then fixing the position of the movable cover 2 by the slider 7.

[0026] This adjustable duct for building ventilation works as follows:

[0027] When in use, first push the friction pattern 503 to make the mechanism base 501 move upward along the trajectory of the first slide groove 4 for a distance, so that the positioning block 504 leaves the positioning slot 508, thereby releasing the fixation of the sliding block 505, and then push the block 507 to move the sliding block 505 away from the mechanism base 501, so that the sliding block 505 leaves the slot 10, and then move the slider 7 along the trajectory of the second slide groove 6, and change the position of the movable cover 2 in the groove 3 by the slider 7, so as to adjust the diameter of the pipeline according to actual needs. After the adjustment is completed, push the block 507 allows a part of the sliding block 505 to pass through the slot 10 and enter the first slide groove 4, and then the friction pattern 503 is pushed to move the mechanism base 501 downward along the trajectory of the first slide groove 4 for a distance, so that the positioning block 504 is inserted into the positioning slot 508, thereby fixing the sliding block 505, and then fixing the position of the slider 7 by the sliding block 505, and then fixing the position of the movable cover 2 by the slider 7, and sealing with the sealing layer 9, and then the pipeline can be used for building ventilation, and the diameter of the pipeline can be flexibly adjusted according to actual needs to expand the scope of application.
