[0034] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an exhaust grille of a building ventilation device, including a ventilation pipe 1, a fixing ring 2 is fixed at the outer edge of one end of the ventilation pipe 1, and mounting holes 3 are drilled at the four corners of the fixing ring 2. The ventilation pipe 1 is provided with an exhaust cavity, and a guide plate 10 is rotatably provided at one end of the exhaust cavity. Several guide plates 10 are equidistantly arranged from top to bottom, and a rotating rod 11 is rotatably provided on the outer side of the ventilation pipe 1, and one end of the rotating rod 11 is fixed to one end of a guide plate 10. An installation cavity 101 is provided inside the ventilation pipe 1 and at the end away from the rotating rod 11, and a fixing disk 102 is rotatably provided inside the installation cavity 101, and the end of the guide plate 10 away from the rotating rod 11 is fixed at the center of the fixing disk 102, and a fixing ear 103 is protruding from the outer edge of the fixing disk 102, and a connecting rod 104 is connected and fixed between the several fixing ears 103, and the fixing ear 103 and the connecting rod 104 are fixed by a pin.

[0035] Through the cooperation between the rotating rod 11 arranged on the ventilation pipe 1 and the installation cavity 101, the fixed disk 102 and the fixed ear 103, etc., the rotating rod 11 can be rotated during operation. During the rotation of the rotating rod 11, a guide plate 10 is driven to rotate as a whole, the guide plate 10 drives the installation cavity 101 to rotate as a whole, the installation cavity 101 drives the fixed disk 102 to rotate as a whole, and the fixed disk 102 drives the fixed ear 103 to move as a whole, thereby causing several fixed disks 102 to rotate synchronously, thereby causing the angle of the guide plate 10 to be adjusted synchronously, and the overall exhaust angle of the guide plate 10 can be effectively adjusted according to different work requirements, and the situation that the overall angle of the exhaust port is fixed and cannot be adjusted is avoided as much as possible, thereby improving the overall applicability of the device.

[0036] like Figure 1 and Figure 3 As shown, a positioning assembly 13 is fixed to one end of the rotating rod 11, and a socket 12 is provided on one side of the ventilation pipe 1 corresponding to the rotating rod 11. There are a number of sockets 12, and the sockets 12 are arranged in a fan-shaped array with the rotating rod 11 as the center. The sockets 12 and the positioning assembly 13 are matched and fixed. The positioning assembly 13 includes a positioning cylinder 14 fixed on the rotating rod 11, and a sliding cavity is provided inside the positioning cylinder 14. A fixed pin 16 is slidingly provided in the sliding cavity, and the fixed pin 16 is matched and plugged in with the socket 12. A fixed rod 17 is fixed to the end of the fixed pin 16 away from the rotating rod 11, and one end of the fixed rod 17 extends out of the positioning cylinder 14, and a return spring 15 is installed in the sliding cavity to assist the fixed pin 16 in pushing.

[0037] Through the cooperation between the positioning assembly 13, the socket 12, and the scale ring 121, the fixing rod 17 is pulled inward. When the fixing rod 17 is pulled, the fixing pin 16 is fixed. In the process of the fixing pin 16 being pulled, the return spring 15 is compressed. After the guide plate 10 is adjusted, the fixed pin 16 can be pushed into the socket 12 under the action of the compressed return spring 15, which can ensure that the guide plate 10 is fixed at the corresponding position.

[0038] A scale ring 121 is embedded and installed on the outer side of the ventilation pipe 1 and corresponding to the outer edge of the insertion hole 12, and angle scale lines are engraved on the scale ring 121.

[0039] By means of the provided scale ring 121 and the angle scale lines thereon, the angle of the rotating rod 11 can be conveniently and effectively determined and interpreted during operation, thereby effectively adjusting the overall tilt angle of the guide plate 10 .

[0040] like Figure 1 and Figure 4 As shown, a plug hole 41 is opened on the ventilation pipe 1, a blocking frame 4 is plugged and installed at the plug hole 41, and a blocking net 42 is embedded and installed on the blocking frame 4.

[0041] By plugging and cooperating with the blocking frame 4 installed on the ventilation pipe 1 and the blocking net 42 thereon, the blocking net 42 can prevent animals or larger impurities from entering the exhaust channel through the exhaust port during operation, and avoid abnormal noise or blockage of the exhaust channel.

[0042] A positioning hole is defined at the top of the insertion hole 41, and a snap-fitting cavity is defined on the outer side of the blocking frame 4. A snap-fitting assembly 5 is mounted in the snap-fitting cavity and cooperates with the positioning hole for positioning. The snap-fitting assembly 5 includes a slide bar 8 vertically fixed in the snap-fitting cavity. The slide bar 8 is sleeved with an ejection spring 9 that is pushed by an auxiliary push plate 7. A push plate 7 is slidably mounted on the slide bar 8. A positioning pin 6 is fixed at the top of the push plate 7, and the positioning pin 6 cooperates with the positioning hole for positioning. A connecting rod is fixed to the outer side of the push plate 7.

[0043] Through the provided clamping assembly 5, the connecting rod drives the pushing plate 7 to move as a whole, and in the process of moving the pushing plate 7, the positioning pin 6 is driven to move as a whole. At the same time, the ejection spring 9 is compressed in the process of pulling the pushing plate 7 downward. At this time, the blocking frame 4 is pushed into the insertion hole 41 as a whole. When the blocking frame 4 is completely pushed into the insertion hole 41, the connecting rod is released, and the positioning pin 6 is driven to be inserted and installed in the positioning hole under the action of the compressed ejection spring 9, which can ensure that the blocking frame 4 can be stably clamped and fixed in the corresponding position during operation.

[0044] The working principle of the technical solution provided by the utility model is as follows:

[0045] Before work, fix the fixing ring 2 at the corresponding exhaust outlet with bolts, insert the blocking frame 4 into the plug-in hole 41, pull the connecting rod inward, and the connecting rod drives the pushing plate 7 to move as a whole. In the process of moving the pushing plate 7, the positioning pin 6 is driven to move as a whole. At the same time, the ejection spring 9 is compressed in the process of pulling the pushing plate 7 down. At this time, the blocking frame 4 is pushed into the plug-in hole 41 as a whole. When the blocking frame 4 is completely pushed into the plug-in hole 41, release the connecting rod, and under the action of the compressed ejection spring 9, the positioning pin 6 is driven to be installed in the positioning hole, thereby effectively blocking and filtering the exhaust outlet through the blocking net 42 on the blocking frame 4.

[0046] When the overall exhaust direction of the ventilation duct 1 needs to be adjusted, the fixing rod 17 is pulled inward. When the fixing rod 17 is pulled, the fixing pin 16 is fixed. In the process of the fixing pin 16 being pulled, the return spring 15 is compressed. At this time, the rotating rod 11 is rotated. In the process of the rotation of the rotating rod 11, a guide plate 10 is driven to rotate as a whole. The guide plate 10 drives the installation cavity 101 to rotate as a whole. The installation cavity 101 drives the fixing plate 102 to rotate as a whole. The fixing plate 102 drives the fixing ear 103 to move as a whole, thereby causing several fixing plates 102 to rotate synchronously, thereby causing the angles of the guide plates 10 to be adjusted synchronously. When the guide plates 10 are adjusted to the specified position, the fixing rod 17 is released, and under the action of the compressed return spring 15, the fixing pin 16 is driven to be pushed into the socket 12, thereby completing the overall adjustment of the overall exhaust direction of the guide plates 10.

[0047] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
