[0019] Embodiment:

[0020] like Figure 1-4As shown, the utility model provides an installed fan shut-off fan for construction, comprising a fan shut-off fan body 1, a mounting head 2 is fixedly provided on the top of the fan shut-off fan body 1, a feeding pipe 3 is snap-connected to the top of the mounting head 2, a first mounting cavity 21 is provided on the side of the mounting head 2, a first spring 22 is fixedly provided on the inner side of the first mounting cavity 21, a connecting block 23 is fixedly provided on the front end of the first spring 22, and the connecting block 23 is slidably connected to the first mounting cavity 21, a connecting groove 31 is provided on the side of the feeding pipe 3, and the connecting groove 31 is snap-connected to the connecting block 23, a mounting block 4 is fixedly provided on the bottom edge of the feeding pipe 3, a second mounting cavity 41 is provided inside the mounting block 4, and a second mounting cavity 41 is fixedly provided on the inner lower side of the second mounting cavity 41 Second spring 42, a movable plate 5 is fixedly provided on the side of the second spring 42, and the movable plate 5 is slidably connected to the second mounting cavity 41, a top of the movable plate 5 is fixedly provided with a push-out block 43, and the push-out block 43 is engaged and connected with the connecting slot 31, a guide column 44 is installed inside the second spring 42, and the guide column 44 is fixedly connected to the mounting block 4, and the guide column 44 is slidably connected to the movable plate 5; when the mounting head 2 and the material delivery pipe 3 are installed, the fan shut-off body 1 is pushed upward to make the mounting head 2 at the bottom of the fan shut-off body 1 move upward, so that the connecting block 23 on the side of the mounting head 2 can be squeezed by the material delivery pipe 3 to make the connecting block 23 retract into the first mounting cavity 21, when the mounting head 2 and the material delivery pipe 3 are fully engaged and connected , the elastic deformation of the first spring 22 pushes the connection block 23 to move, so that the connection block 23 is inserted into the connection slot 31, so that the connection block 23 and the material delivery pipe 3 are fixedly connected, and the fixed connection between the material delivery pipe 3 and the mounting head 2 is realized. When the mounting head 2 and the material delivery pipe 3 are separated, the moving plate 5 inside the mounting block 4 on the side of the material delivery pipe 3 is moved. When the moving plate 5 moves, it drives the ejection block 43 to move, so that the ejection block 43 pushes the connection block 23 inside the connection slot 31, so that the connection block 23 can be separated from the material delivery pipe 3. At this time, the mounting head 2 and the material delivery pipe 3 can be separated, and under the push of the elastic deformation of the second spring 42, when the moving plate 5 is not in use When the ejection block 43 is in the state of being pressed against the second mounting cavity 41, it can be made to fit with the side surface of the second mounting cavity 41, thus preventing the ejection block 43 from pushing the connecting block 23. In the absence of external force, the ejection block 43 cannot push the connecting block 23. Through this design, under the action of the first mounting cavity 21, the first spring 22, the connecting block 23, and the connecting slot 31, the mounting head 2 and the material conveying pipe 3 can be conveniently installed.

With such a design, the problem of complicated disassembly and assembly of traditional punching bolts is solved, thereby reducing the difficulty and workload of the work and increasing the work efficiency.

[0021] Among them, a through hole is opened inside the movable plate 5, and the internal cross-section of the through hole and the cross-section of the guide column 44 are both rectangular; by setting the cross-section of the through hole and the guide column 44 to be rectangular, the positioning of the movable plate 5 during movement can be ensured, and the stability of the ejection block 43 when it moves toward the connecting slot 31 can be ensured, so that the ejection block 43 can stably push the connecting block 23 inside the connecting slot 31.

[0022] Among them, the lower internal width of the second installation cavity 41 is adapted to the width of the movable plate 5; by adapting the sizes of the second installation cavity 41 and the movable plate 5, when the movable plate 5 moves in the lower internal part of the second installation cavity 41, the stability of the movable plate 5 can be guaranteed and the position displacement of the movable plate 5 can be avoided.

[0023] Among them, the cross-section of the ejection block 43 is adapted to the internal width of the connecting slot 31; by adapting the sizes of the ejection block 43 and the connecting slot 31, the ejection block 43 can stably push the connecting block 23 when pushing the connecting block 23.

[0024] Among them, the lower internal width of the feed pipe 3 is adapted to the width of the mounting head 2, and the internal width of the first mounting cavity 21 is adapted to the tail end width of the connecting block 23; by adapting the dimensions of the first mounting cavity 21 and the connecting block 23, the stability of the connecting block 23 when slidingly connected inside the first mounting cavity 21 can be ensured, and position displacement can be avoided.

[0025] Among them, the front end top of the connecting block 23 is inclined, and the cross-section of the mounting block 4 is set in an L shape; by setting the shape of the front end top of the connecting block 23, when the mounting head 2 and the feed pipe 3 are engaged and connected, the connecting block 23 can be squeezed through the inclined surface, so that the connecting block 23 moves into the first mounting cavity 21, so that the mounting head 2 and the feed pipe 3 are engaged and connected more conveniently.
