[0023] Please see Figure 1 , Figure 2 and Figure 4This invention proposes a telescopic ventilation net 10 for electrical cabinets. The telescopic ventilation net 10 includes a fixed base plate 13, a first telescopic plate 11, and a second telescopic plate 12. Connectors 14 are provided at both ends of the fixed base plate 13, and the connectors 14 constrain the first telescopic plate 11 and the second telescopic plate 12 to the same plane. A transmission mechanism is provided at the lower end of the fixed base plate 13. A first telescopic component is provided at the lower end of the first telescopic plate 11, which is driven to drive the transmission mechanism. A second telescopic component is provided at the lower end of the second telescopic plate 12, which is driven to drive the transmission mechanism. By rotating the transmission mechanism, the first telescopic component and the second telescopic component are driven to move the first telescopic plate 11 and the second telescopic plate 12 along the length direction of the connector 14.

[0024] In this embodiment, the telescopic breathable mesh 10 includes a fixed base plate 13, a first telescopic plate 11, and a second telescopic plate 12. When the telescopic breathable mesh 10 is in a contracted state (see details...), Figure 4 The first telescopic plate 11 and the second telescopic plate 12 are disposed below the fixed base plate 13; more specifically, the total width of the first telescopic plate 11 and the second telescopic plate 12 in the minor axis direction is less than or equal to the width of the fixed base plate 13 in the minor axis direction.

[0025] The fixed base plate 13 has connectors 14 at both ends. The fixed base plate 13 and the connectors 14 are an integral structure. The connectors 14 constrain the first telescopic plate 11 and the second telescopic plate 12 to the same plane. The lower end of the fixed base plate 13 is provided with a transmission mechanism. The lower end of the first telescopic plate 11 is provided with a first telescopic component that is connected to the transmission mechanism. The lower end of the second telescopic plate 12 is provided with a second telescopic component that is connected to the transmission mechanism. By rotating the transmission mechanism, the first telescopic component and the second telescopic component are driven to move the first telescopic plate 11 and the second telescopic plate 12 along the length direction of the connectors 14, thereby realizing the flexible adjustment of the height of the telescopic breathable net 10.

[0026] In one embodiment, such as Figure 4 , Figure 5 and Figure 6As shown, the transmission mechanism includes a transmission rod 133 and two fixed gear assemblies, which are respectively disposed at both ends of the fixed base plate 13. Transmission gears 134 are disposed at both ends of the transmission rod 133, and each transmission gear 134 corresponds to one of the fixed gear assemblies, with each transmission gear 134 being drive-connected to its corresponding fixed gear assembly. The first telescopic assembly includes two first telescopic members 111, each corresponding to one of the fixed gear assemblies, with each first telescopic member 111 being drive-connected to its corresponding fixed gear assembly. The second telescopic assembly includes two second telescopic members 121, each corresponding to one of the fixed gear assemblies, with each second second telescopic member 121 being drive-connected to its corresponding fixed gear assembly.

[0027] In this embodiment, transmission gears 134 are provided at both ends of the transmission rod 133. The transmission gears 134 correspond one-to-one with the fixed gear assemblies. The two transmission gears 134 are connected to their respective fixed gear assemblies. When the transmission rod 133 is rotated, the transmission gears 134 drive the corresponding fixed gear assemblies to rotate synchronously.

[0028] The first telescopic assembly includes two first telescopic members 111, which are respectively disposed at both ends of the first telescopic plate 11. Each first telescopic member 111 corresponds to a fixed gear assembly, and the two first telescopic members 111 are driveably connected to their respective fixed gear assemblies. The second telescopic assembly includes two second telescopic members 121, which are respectively disposed at both ends of the second telescopic plate 12. Each second telescopic member 121 corresponds to a fixed gear assembly, and the two second telescopic members 121 are driveably connected to their respective fixed gear assemblies. When the transmission rod 133 is rotated, the transmission gear 134 drives the corresponding fixed gear assembly to rotate synchronously. When the fixed gear assembly rotates, it drives the first telescopic assembly and the second telescopic assembly to move synchronously, thereby driving the first telescopic plate 11 and the second telescopic plate 12 to move along the length direction of the connecting member 14. During the movement of the first telescopic plate 11 and the second telescopic plate 12, they always maintain an operating state of either moving away from or moving closer to each other. When the first telescopic plate 11 and the second telescopic plate 12 move away from each other, the height of the telescopic ventilation net 10 will increase; when the first telescopic plate 11 and the second telescopic plate 12 move closer to each other, the height of the telescopic ventilation net 10 will decrease. This achieves flexible adjustment of the height of the telescopic ventilation net 10. Therefore, the telescopic ventilation net 10 can be adapted to electrical cabinets of different specifications and has high versatility.

[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixed gear assembly includes a first fixed gear 131 and a second fixed gear 132. The first fixed gear 131 and the second fixed gear 132 are coaxially arranged. The first fixed gear 131 is disposed on the side close to the fixed base plate 13. The first fixed gear 131 meshes with the corresponding first telescopic member 111 and the corresponding second telescopic member 121. The second fixed gear 132 meshes with the corresponding transmission gear 134.

[0030] In this embodiment, the first fixed gear 131 meshes simultaneously with the racks of the corresponding first telescopic member 111 and the corresponding second telescopic member 121, and the second fixed gear 132 meshes with the corresponding transmission gear 134. When the transmission rod 133 is rotated, the transmission gear 134 drives the two second fixed gears 132 to rotate synchronously, which in turn drives the first fixed gear 131 to rotate synchronously. When the first fixed gear 131 rotates, it drives the corresponding first telescopic member 111 and the corresponding second telescopic member 121 to rotate synchronously, thereby driving the first telescopic plate 11 and the second telescopic plate 12 to move along the length direction of the connecting member 14. The present invention can drive the first telescopic plate 11 and the second telescopic plate 12 to move closer or further apart by rotating the transmission rod 133, thereby realizing flexible adjustment of the height of the telescopic breathable net 10.

[0031] In one embodiment, such as Figure 3 and Figure 6 As shown, the connector 14 is provided with a sliding block 141, and the first telescopic plate 11 and the second telescopic plate 12 are both provided with sliding grooves 142 that are adapted to the sliding block 141.

[0032] In this embodiment, when the first telescopic plate 11 and the second telescopic plate 12 move, the sliding groove 142 slides relative to the fixed sliding block 141. The sliding block 141 is used to guide the sliding direction of the first telescopic plate 11 and the second telescopic plate 12, so that the first telescopic plate 11 and the second telescopic plate 12 are always on the same plane.

[0033] In one embodiment, such as Figure 3 and Figure 6 As shown, the end of the first telescopic member 111 is provided with a first travel limit member 112, which is used to limit the maximum telescopic travel of the first telescopic member 111; the end of the second telescopic member 121 is provided with a second travel limit member 122, which is used to limit the maximum telescopic travel of the second telescopic member 121.

[0034] In this embodiment, the first travel limit member 112 is a protrusion or block provided at the end of the first telescopic member 111. When the first telescopic member 111 extends to the maximum position, the first travel limit member 112 abuts against the corresponding first fixed gear 131 to prevent the first telescopic member 111 from disengaging and to achieve the limiting effect.

[0035] The second travel limiter 122 is a protrusion or stop provided at the end of the second telescopic member 121. When the second telescopic member 121 extends to its maximum position, the second travel limiter 122 abuts against the corresponding first fixed gear 131 to prevent the second telescopic member 121 from disengaging, thus achieving a limiting effect (see details). Figure 3 ).

[0036] In one embodiment, such as Figure 3 and Figure 6 As shown, the first telescopic member 111 is fixedly mounted on the lower end of the first telescopic plate 11 by the first bolt.

[0037] In this embodiment, each of the first telescopic members 111 is fixedly mounted on the lower end of the first telescopic plate 11 by a first bolt and is connected to its corresponding fixed gear assembly for transmission. When the transmission rod 133 is rotated, the transmission gear 134 drives the corresponding fixed gear assembly to rotate synchronously. When the two fixed gear assemblies rotate, they drive their respective first telescopic members 111 to move synchronously, thereby driving the first telescopic plate 11 to move along the length direction of the connecting member 14.

[0038] In one embodiment, such as Figure 3 and Figure 6 As shown, the second telescopic member 121 is fixedly mounted on the lower end of the second telescopic plate 12 by a second bolt.

[0039] In this embodiment, the second telescopic members 121 are all fixedly mounted on the lower end of the second telescopic plate 12 by second bolts and are connected to their respective fixed gear assemblies for transmission. When the transmission rod 133 is rotated, the transmission gear 134 drives the corresponding fixed gear assembly to rotate synchronously. When the two fixed gear assemblies rotate, they drive their respective second telescopic plates 12 to move synchronously, thereby driving the second telescopic plates 12 to move along the length direction of the connecting member 14.

[0040] In one embodiment, such as Figure 5 and Figure 6As shown, the transmission mechanism also includes a plurality of connecting blocks 135, which are disposed at the lower end of the fixed base plate 13. Each connecting block 135 is provided with a limiting groove that is adapted to the transmission rod 133, and the transmission rod 133 is rotatably disposed in the limiting groove.

[0041] In this embodiment, the transmission mechanism further includes a plurality of connecting blocks 135, which are spaced apart along the length of the fixed base plate 13; each connecting block 135 is provided with a limiting groove adapted to the transmission rod 133, and the transmission rod 133 is rotatably disposed in the limiting groove.

[0042] More specifically, the opening size of the limiting groove is smaller than the outer diameter of the transmission rod 133, and the transmission rod 133 can be elastically inserted into the limiting groove.

[0043] When the user needs to adjust the height of the telescopic breathable net 10, the transmission rod 133 can be rotated to make the transmission gears 134 at both ends of the transmission rod 133 drive the corresponding fixed gear assemblies to rotate synchronously. When the two fixed gear assemblies rotate, they drive the first telescopic assembly and the second telescopic assembly to move synchronously, thereby driving the first telescopic plate 11 and the second telescopic plate 12 to move along the length direction of the connector 14, thereby realizing the flexible adjustment of the height of the telescopic breathable net 10.

[0044] In one embodiment, such as Figure 1 and Figure 7 As shown, a fixing member 143 is provided on the connector 14, and the telescopic breathable net 10 is fixedly installed on the electrical cabinet 20 through the fixing member 143.

[0045] In this embodiment, the height of the telescopic ventilation net 10 can be adjusted according to the model of the electrical cabinet 20 and / or the usage requirements. After the adjustment is completed, the telescopic ventilation net 10 is fixedly installed on the electrical cabinet 20 by the fastener 143.

[0046] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixed base plate 13, the first telescopic plate 11 and the second telescopic plate 12 are each provided with a plurality of ventilation holes 15, and the ventilation holes are waist-shaped holes.

[0047] In this embodiment, the fixed base plate 13, the first telescopic plate 11 and the second telescopic plate 12 are each provided with a plurality of ventilation holes 15. The ventilation holes 15 on each plate are arranged in an array. The ventilation holes are waist-shaped holes, which can effectively improve the ventilation and heat dissipation effect.

[0048] This invention discloses a telescopic ventilation mesh for electrical cabinets. The telescopic ventilation mesh includes a fixed base plate, a first telescopic plate, and a second telescopic plate. Connectors are provided at both ends of the fixed base plate, constraining the first and second telescopic plates to the same plane. A transmission mechanism is provided at the lower end of the fixed base plate. A first telescopic component, which is drively connected to the transmission mechanism, is provided at the lower end of the first telescopic plate, and a second telescopic component, which is drively connected to the transmission mechanism, is provided at the lower end of the second telescopic plate. By rotating the transmission mechanism, the first and second telescopic components are driven to move the first and second telescopic plates along the length direction of the connectors. This invention allows for flexible height adjustment of the telescopic ventilation mesh by rotating the transmission mechanism to drive the first and second telescopic components to move the first and second telescopic plates along the length direction of the connectors. Therefore, the telescopic ventilation mesh can adapt to electrical cabinets of different specifications, exhibiting high versatility.

[0049] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
