Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically to an intelligent building ventilation device. Background Technology

[0002] Intelligent buildings utilize building automation systems, employing advanced computer control technology, management software, and energy-saving system programs to ensure the orderly, coordinated, and scientific operation of electromechanical equipment within the building or building complex. Exhaust systems are an essential component of intelligent buildings, achieving ventilation by drawing air from indoors or outdoors.

[0003] However, during the installation of existing ventilation devices, after inserting the ventilation pipe into the pre-drilled hole, the excess part needs to be cut off, and then tools and multiple bolts are used to fix the ventilation pipe, which is labor-intensive and has low installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent building ventilation device to solve the problem of cumbersome and complicated installation process mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent building ventilation device, comprising:

[0006] The abutment plate has a slide cylinder fixedly installed at one end. A base cylinder is connected to the outer wall of the slide cylinder at the end away from the abutment plate. A screw rod passes through the interior of the slide cylinder and the base cylinder at their contact positions. Slider blocks are provided inside the four sides of the base cylinder. A shaft rod is fixedly connected to the inner side of the slider rod. A rotating abutment plate is connected to the outer wall of the shaft rod. A threaded ring is connected to the outer wall of the base cylinder at the end away from the slide cylinder. An exhaust hood is fixedly installed at the end of the base cylinder away from the slide cylinder.

[0007] Preferably, the sliding cylinder has four sets of holes corresponding to the size of the screw, the base cylinder has one set of holes corresponding to the size of the screw, and the sliding cylinder and the base cylinder are slidably connected.

[0008] Preferably, both the slide cylinder and the base cylinder are hollow inside, and the surface of the base cylinder has a groove corresponding to the size of the slider.

[0009] Preferably, the slider is slidably connected to the base cylinder, and the rotating abutment is rotatably connected to the shaft.

[0010] Preferably, the screw ring does not contact the slider when it is turned, and the end of the rotating abutment that is perpendicular to the base cylinder and away from the shaft is located outside the screw ring.

[0011] Preferably, the screw ring is threadedly connected to the base cylinder, and the diameter of the screw ring is the diameter of the pre-drilled wall hole.

[0012] Preferably, the diameter of the abutment plate on the side closer to the slide is the same as that of the threaded ring, and the diameter of the abutment plate on the side farther from the slide is larger than that of the threaded ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Before installation, this new type of exhaust device requires drilling a hole in the wall according to the diameter of the screw ring. The total length of the sliding cylinder and the base cylinder is adjusted according to the wall thickness. The screw is then passed through the holes in the sliding cylinder and the base cylinder for positioning and fixation. The exhaust cap is then passed from the inside of the wall to the outside. After the rotating abutment plate moves to the outside of the wall, it is rotated until it is perpendicular to the base cylinder. The screw ring is then turned, causing the rotating abutment plate, shaft, and slider to move, thus bringing the rotating abutment plate into contact with the outside of the wall. This completes the installation of the exhaust device. The operation is simple and quick, and the length of the exhaust pipe can be adjusted, improving practicality, speeding up installation, reducing labor intensity, and increasing installation efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5One embodiment of this utility model is an intelligent building ventilation device. The ventilation cap 09 used in this application is a product that can be directly purchased on the market. Its principle and connection method are existing technologies known to those skilled in the art, so they will not be described in detail here.

[0023] Includes: a receiving plate 01, a sliding cylinder 02 fixedly installed at one end of the receiving plate 01, a base cylinder 03 connected to the outer wall of the end of the sliding cylinder 02 away from the receiving plate 01, the total length of the sliding cylinder 02 and the base cylinder 03 can be adjusted to adapt to the thickness of the wall, a screw 04 passes through the inside of the contact position of the sliding cylinder 02 and the base cylinder 03, the screw 04 passes through the holes of the sliding cylinder 02 and the base cylinder 03 to fix the position of the sliding cylinder 02 and the base cylinder 03, sliders 05 are set inside the four sides of the base cylinder 03, a shaft 06 is fixedly connected to the inner side of the slider 05, a rotating abutment plate 07 is connected to the outer wall of the shaft 06, the rotating abutment plate 07 can abut against the outer side of the wall after being perpendicular to the base cylinder 03, a screw ring 08 is connected to the outer wall of the end of the base cylinder 03 away from the sliding cylinder 02, and an exhaust hood 09 is fixedly installed at the end of the base cylinder 03 away from the sliding cylinder 02.

[0024] Furthermore, the slide cylinder 02 has four sets of holes corresponding to the size of the screw 04, and the base cylinder 03 has one set of holes corresponding to the size of the screw 04. The slide cylinder 02 and the base cylinder 03 are slidably connected, and the total length of the slide cylinder 02 and the base cylinder 03 can be adjusted to adapt to the thickness of the wall.

[0025] Furthermore, both the slide cylinder 02 and the base cylinder 03 are hollow inside, which does not affect ventilation. The surface of the base cylinder 03 is provided with a groove corresponding to the size of the slider 05, ensuring that the base cylinder 03 does not affect the movement of the slider 05, and can drive the shaft 06 and the rotating abutment 07 to move.

[0026] Furthermore, the slider 05 is slidably connected to the base cylinder 03, ensuring that the base cylinder 03 does not affect the movement of the slider 05, and can drive the shaft 06 and the rotating abutment 07 to move. The rotating abutment 07 is rotatably connected to the shaft 06.

[0027] Furthermore, the screw ring 08 does not contact the slider 05 when it is turned, ensuring that the slider 05 does not affect the turning of the screw ring 08. After the rotating abutment plate 07 is rotated to be perpendicular to the base cylinder 03, the end away from the shaft 06 is located outside the screw ring 08. After the rotating abutment plate 07 is perpendicular to the base cylinder 03, it can be pressed against the outside of the wall.

[0028] Furthermore, the screw ring 08 is threadedly connected to the base cylinder 03 to ensure that the position of the screw ring 08 will not easily move when it is screwed. The diameter of the screw ring 08 is the diameter of the wall hole that was pre-drilled.

[0029] Furthermore, the diameter of the side of the abutment plate 01 closest to the slide cylinder 02 is the same as that of the screw ring 08. After installation, both ends fit into the wall hole, ensuring the stability after installation. The diameter of the side of the abutment plate 01 furthest from the slide cylinder 02 is larger than that of the screw ring 08. After installation, the side of the abutment plate 01 furthest from the slide cylinder 02 rests against the inner side of the wall.

[0030] Working principle: First, a hole is made in the wall according to the diameter of the screw ring 08. Adjust the total length of the sliding cylinder 02 and the base cylinder 03 according to the wall thickness. Pass the screw rod 04 through the holes in the sliding cylinder 02 and the base cylinder 03 for positioning and fixation. Insert the exhaust hood 09 from the inside of the wall to the outside. After the rotating abutment plate 07 moves to the outside of the wall, rotate it until it is perpendicular to the base cylinder 03. Tighten the screw ring 08. The screw ring 08 drives the rotating abutment plate 07, the shaft 06, and the slider 05 to move, causing the rotating abutment plate 07 to fit against the outside of the wall, thus completing the installation of the exhaust device. The above is the complete working principle of this utility model.
