Description

Technical Field

[0001] This utility model relates to the field of louver structure technology, and in particular to a composite louver. Background Technology

[0002] In modern industry and daily life, louvers are widely used in various places as a common ventilation, light-blocking, and protective device. Louvers used in electrical distribution cabinets, in particular, must not only have basic ventilation functions but also meet special requirements such as ease of maintenance and dust prevention. A composite louver has emerged, combining multiple functional characteristics to better adapt to the requirements of use in complex environments.

[0003] Traditional electrical control cabinet louvers typically employ a relatively simple mechanical structure. Generally, the frame and louver body are connected by simple pins or screws. Adjustment is usually done manually by directly turning the slats, or by using a horizontal bar fixed to the frame, moving the bar to rotate the slats. For dust prevention, most simply have a fixed filter installed on the frame, lacking a flexible dustproof structure.

[0004] However, traditional venetian blinds have some drawbacks in practical use. Disassembly and installation are extremely inconvenient. Regular cleaning, maintenance, or replacement of damaged parts requires screws and other tools, making the process cumbersome and time-consuming. Furthermore, due to limited space and inconvenient operation, improper force can easily damage the frame, increasing maintenance costs and potentially rendering the blinds unusable. This affects the efficiency of maintaining and replacing the blind frame, causing inconvenience for users in repairing, cleaning, or replacing parts of the internal structure, and reducing ease of use. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a composite louver, which aims to improve the problem that traditional louvers are inconvenient to disassemble and install, requiring tools for disassembly, which is cumbersome and can easily damage the window frame.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite louver, comprising a power distribution cabinet door panel, a support frame fixedly connected to the inner wall of the power distribution cabinet door panel, a louver frame slidably connected to the inner wall of the support frame, window slats rotatably connected to the inner wall of the louver frame, a disassembly assembly provided on the outer wall of the support frame, and a dustproof assembly provided on the surface of the support frame.

[0007] The disassembly assembly includes a fixed shaft, the outer wall of which is fixedly connected to the outer wall of the support frame. A connecting shaft is slidably connected to the inner wall of the support frame. A switch is fixedly connected to one end of the connecting shaft, and a fixed shaft is fixedly connected to the other end of the connecting shaft. An elastic spring is sleeved on the outer wall of the connecting shaft. A sliding groove is provided on the inner wall of the support frame, and an arc-shaped fixing groove is provided on the inner wall of the louver frame.

[0008] Furthermore, the dustproof component includes a dustproof net, the outer wall of which is slidably connected to the inner wall of the support frame, a second switch is rotatably connected to the outer wall of the support frame, a second connecting shaft is fixedly connected to the outer wall of the second switch, a torsion spring is sleeved on the outer wall of the second connecting shaft, and a fixing block is fixedly connected to one end of the second connecting shaft.

[0009] Furthermore, the fixing block is rotatably connected to the inner wall of the support frame, and the fixing block is used to limit the position of the dustproof net.

[0010] Furthermore, the outer wall of the fixed block is rotatably connected to the inner wall of the dustproof net, which is used to isolate dust and debris.

[0011] Furthermore, the outer wall of the torsion spring is fixedly connected to the inner wall of the support frame, and the torsion spring is used to drive the second connecting shaft to rotate.

[0012] Furthermore, the outer wall of the connecting shaft is slidably connected inside the slide groove, and the elastic spring is used to fix the louver frame.

[0013] Furthermore, the outer wall of the connecting shaft is rotatably connected inside the arc-shaped fixing groove, which is used to limit the position of the connecting shaft.

[0014] Furthermore, one end of the elastic spring is fixedly connected to the inner wall of the fixed shaft, and the elastic spring is used to push the connecting shaft to move.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the switch is pressed, the connecting shaft slides along the slide groove and compresses the spring. After disengaging from the arc-shaped fixing groove, the louver frame is removed. During installation, after aligning with the louver frame, the switch is released, and the spring pushes the connecting shaft back into place to fix the louver frame. This solves the problem that traditional louver disassembly and installation are inconvenient in actual use. Traditional louver disassembly requires tools, is cumbersome, and is prone to damaging the window frame. This invention achieves the goal of improving the efficiency of maintaining and replacing louver frames, reducing maintenance costs, and making it convenient for users to repair, clean, or replace parts of the internal structure of the louver, thus improving the ease of use.

[0017] 2. In this utility model, when the dustproof component is running, turning the switch drives the connecting shaft and the fixing block to rotate, releasing the limit on the dustproof net, unfolding the dustproof net to prevent dust. When cleaning, the dustproof net is slid back to its original position, and turning the switch again twists the spring to make the fixing block limit the dustproof net again, thus achieving the effect of protecting the normal operation of electrical components in the distribution cabinet, reducing faults caused by dust, extending the service life of the distribution cabinet, and reducing maintenance costs and frequency.

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.

[0025] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a composite louver, comprising a power distribution cabinet door panel 1, a support frame 2 fixedly connected to the inner wall of the power distribution cabinet door panel 1, a louver frame 5 slidably connected to the inner wall of the support frame 2, a louver leaf 4 rotatably connected to the inner wall of the louver frame 5, a disassembly assembly provided on the outer wall of the support frame 2 for disassembling the louver leaf, and a dustproof assembly provided on the surface of the support frame 2 for blocking dust.

[0026] The disassembly assembly includes a fixed shaft 10, the outer wall of which is fixedly connected to the outer wall of the support frame 2. A connecting shaft 12 is slidably connected to the inner wall of the support frame 2. A switch 3 is fixedly connected to one end of the connecting shaft 12, and the other end of the connecting shaft 12 is fixedly connected to the fixed shaft 10. An elastic spring 13 is sleeved on the outer wall of the connecting shaft 12. A sliding groove 8 is provided on the inner wall of the support frame 2, and an arc-shaped fixing groove 9 is provided on the inner wall of the louver frame 5.

[0027] Specifically, when switch 3 is pressed, connecting shaft 12 slides along slide groove 8 and compresses elastic spring 13 until it disengages from arc-shaped fixing groove 9, and louver frame 5 can be removed; during installation, after aligning louver frame 5 with support frame 2, switch 3 is released, and elastic spring 13 restores its deformation, pushing connecting shaft 12 back into arc-shaped fixing groove 9 to complete the fixing.

[0028] Reference Figure 1 , Figure 2 and 4 The dustproof component includes a dustproof net 6, the outer wall of which is slidably connected to the inner wall of the support frame 2. A second switch 7 is rotatably connected to the outer wall of the support frame 2. A second connecting shaft 15 is fixedly connected to the outer wall of the second switch 7. A torsion spring 11 is sleeved on the outer wall of the second connecting shaft 15. A fixing block 14 is fixedly connected to one end of the second connecting shaft 15. The fixing block 14 is rotatably connected to the inner wall of the support frame 2 and is used to limit the movement of the dustproof net 6. The outer wall of the fixing block 14 is rotatably connected to the inner wall of the dustproof net 6. The dustproof net 6 is used to isolate... To prevent dust and debris from entering, the outer wall of the torsion spring 11 is fixedly connected to the inner wall of the support frame 2. The torsion spring 11 is used to drive the second connecting shaft 15 to rotate. The outer wall of the first connecting shaft 12 is slidably connected to the inside of the slide groove 8. The elastic spring 13 is used to fix the louver frame 5. The outer wall of the first connecting shaft 12 is rotatably connected to the inside of the arc-shaped fixing groove 9. The arc-shaped fixing groove 9 is used to limit the movement of the first connecting shaft 12. One end of the elastic spring 13 is fixedly connected to the inner wall of the fixing shaft 10. The elastic spring 13 is used to push the first connecting shaft 12 to move.

[0029] Specifically, rotating switch 7 causes connecting shaft 15 and fixing block 14 to rotate, releasing the limit on dustproof net 6 and unfolding dustproof net 6 to isolate dust and debris; when cleaning dustproof net 6, slide it back to the initial position, rotate switch 7 again, torsion spring 11 causes connecting shaft 15 to rotate in the opposite direction, and fixing block 14 limits dustproof net 6 again.

[0030] Working principle: When a composite venetian blind is needed, and when the venetian blind frame 5 needs to be disassembled, first press switch 3 by hand. Switch 3 drives the connecting shaft 12 to slide along the slide groove 8 inside the support frame 2. During this process, the connecting shaft 12 will compress the elastic spring 13. As the connecting shaft 12 slides, the elastic spring 13 is compressed and undergoes elastic deformation. When the connecting shaft 12 moves to a certain position, it will disengage from the limit of the arc-shaped fixing groove 9 inside the venetian blind frame 5. At this time, the venetian blind frame 5 is no longer fixed and can be easily removed from the support frame 2. When installing the venetian blind frame 5, first align the venetian blind frame 5 with the support frame 2 and find a suitable installation position. Then release switch 3. At this time, the compressed elastic spring 13 will recover its deformation, generating a force that pushes the connecting shaft 12. Under the action of this force, the connecting shaft 12 moves and rotates back inside the arc-shaped fixing groove 9. The arc-shaped fixing groove 9 limits the connection shaft 12, thereby firmly fixing the louver frame 5 inside the support frame 2. In addition, when the distribution cabinet needs dust protection, the switch 7 is manually turned. Turning the switch 7 will drive the connection shaft 15 to rotate together. The connection shaft 15 will also drive the fixing block 14 to rotate. The fixing block 14 originally limited the dustproof net 6. After rotation, this limitation is released, and the dustproof net 6 can be removed. The dustproof net 6 can effectively isolate dust and debris and prevent them from entering the distribution cabinet. When the dustproof net 6 needs to be cleaned, first slide the dustproof net 6 back to the initial position along the support frame 2. Then turn the switch 7 again. At this time, the torsion spring 11 plays a role and drives the connection shaft 15 to rotate in the opposite direction. The connection shaft 15 drives the fixing block 14 to rotate in the opposite direction. The fixing block 14 limits the dustproof net 6 again, keeping the dustproof net 6 in a fixed position for easy use next time.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
