Description

Technical Field

[0001] The utility model relates to the field of switch installation, in particular to a dust-proof cover for a power information switch. Background Technique

[0002] A switch is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes accessing the switch. The switch means "switch", and it can, according to the needs of transmitting information at both ends of communication, send the information to be transmitted to the corresponding route that meets the requirements through manual or device-automatic methods.

[0003] Existing switches are mostly placed in weak current rooms. Due to the small space and lack of decoration in the weak current room, there is too much dust in the weak current room. Since the switch has multiple groups of interfaces and most of the interfaces are not all used, a large amount of dust accumulates in the interfaces, which in turn affects the normal contact after the line is connected and the function of the switch. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust-proof cover for a power information switch to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dust-proof cover for a power information switch, including a mounting plate. A sliding groove is opened inside the mounting plate, and a number of moving blocks are slidably connected inside the sliding groove. Communication grooves communicating with the sliding groove are opened on the upper and lower sides of the mounting plate. Limiting blocks are fixedly connected to the upper and lower ends of the moving block, and the limiting blocks are slidably connected inside the communication groove. A first threaded rod is threadedly connected inside the moving block, the tail end of the first threaded rod is rotatably connected to a connecting plate, and the other end of the connecting plate is fixedly connected to a plug.

[0006] Preferably, a second threaded rod is fixedly connected to the upper part of the upper limiting block, and the upper part of the second threaded rod penetrates the outside of the communication groove and is threadedly connected to a fixing nut.

[0007] Preferably, a connecting rod is fixedly connected to the lower part of the lower limiting block, and the lower part of the connecting rod penetrates the communication groove and is fixedly connected to a fixing piece.

[0008] Preferably, a rotating shaft is rotatably connected to the upper parts of both ends of the mounting plate, a rotating disk is fixedly connected to the upper part of the rotating shaft, a third threaded rod is fixedly connected to the upper part of the rotating disk, and a threaded hole matching the third threaded rod is opened in the lower part of the mounting plate.

[0012] 1. In the present utility model, the mounting plate is fixed to the outside of the switch through the adhesive sticker, and the sliding groove of the switch is aligned with the switch jack. By rotating the first threaded rod, the plug is driven to insert into the switch jack, so as to realize dust prevention for the unused switch jack. By rotating the fixing nut, the fixing nut presses the upper part of the mounting plate to lock the position of the moving block, which can block and prevent dust for the unused jacks in the switch, preventing a large amount of dust from adhering to the switch jacks exposed in the air, resulting in poor signal contact.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, the present utility model provides a technical solution: a dust-proof cover for a power information switch, including a mounting plate 1. A sliding groove 2 is formed inside the mounting plate 1. A plurality of groups of moving blocks 3 are slidably installed inside the sliding groove 2. Communication grooves 7 communicating with the sliding groove 2 are formed on the upper and lower sides of the mounting plate 1. Limit blocks 8 are fixedly welded to the upper and lower ends of the moving blocks 3. The limit blocks 8 are slidably installed inside the communication grooves 7 to prevent the moving blocks 3 from detaching from the sliding groove 2. A first threaded rod 4 is threadedly installed inside the moving blocks 3. A connecting plate 5 is rotatably installed at the tail end of the first threaded rod 4. A plug 6 is fixedly welded to the other end of the connecting plate 5. The size of the plug 6 matches the size of the standard switch jack. By pushing the moving blocks 3 along the sliding groove 2, the plug 6 is aligned with the unused switch jack. By rotating the first threaded rod 4, the plug 6 is driven to insert into the switch jack, realizing dust prevention for the unused switch jack;

[0020] A second threaded rod 9 is fixedly welded to the upper part of the upper limit block 8. The upper part of the second threaded rod 9 penetrates the outside of the communication groove 7 and is threadedly installed with a fixing nut 10. By rotating the fixing nut 10, the fixing nut 10 presses the upper part of the mounting plate 1. Continuing to rotate the fixing nut 10, the second threaded rod 9 and the limit block 8 drive the moving block 3 to move upward, so that the moving block 3 presses the upper inner wall of the sliding groove 2, locking the position of the moving block 3; A connecting rod 11 is fixedly welded to the lower part of the lower limit block 8. The lower part of the connecting rod 11 penetrates the communication groove 7 and is fixedly welded with a fixing piece 12. When the moving block 3 moves upward, the fixing piece 12 is driven to move upward through the connecting rod 11, thereby pressing the lower wall of the mounting plate 1 and improving the fixing effect; Rotating shafts 13 are rotatably installed at the upper parts of both ends of the mounting plate 1. A rotating disk 14 is fixedly welded to the upper part of the rotating shaft 13. A third threaded rod 15 is fixedly welded to the upper part of the rotating disk 14. A threaded hole 17 matching the third threaded rod 15 is formed in the lower part of the mounting plate 1. By rotating the rotating disk 14, the third threaded rod 15 rotates and inserts into the threaded hole 17 in the lower part of the upper set of mounting plates 1, realizing the installation between two sets of mounting plates 1 and protecting the double-row switch jacks; Two pushing rods 16 are fixedly welded to the outside of the rotating disk 14, facilitating the rotation of the rotating disk 14 in the gap between the mounting plates 1; Connecting pieces 18 are fixedly welded to both sides of the mounting plate 1. A sticky patch 19 is fixedly connected to the side of the connecting piece 18 facing the plug 6. The mounting plate 1 is fixed to the outside of the switch through the sticky patch 19 to prevent the plug 6 from falling off.

[0021] Working principle: When the utility model is in use, the rotating disk 14 is rotated through the connecting rod 11, and the third threaded rod 15 rotates and is inserted into the threaded hole 17 at the lower part of the upper set of mounting plates 1, so as to realize the installation between the two sets of mounting plates 1. The mounting plate 1 is fixed to the outer side of the switch through the adhesive sticker 19, and the sliding groove 2 on the switch is opposite to the switch jack. By rotating the first threaded rod 4, the plug 6 is driven to insert into the switch jack, so as to realize dust prevention for the unused switch jack. By rotating the fixing nut 10, the fixing nut 10 presses the upper part of the mounting plate 1. Continuing to rotate the fixing nut 10, the second threaded rod 9 and the limiting block 8 drive the moving block 3 to move upward, so that the moving block 3 presses the inner wall on the upper side of the sliding groove 2, and the position of the moving block 3 is locked. When the moving block 3 moves upward, the fixing piece 12 is driven to move upward through the connecting rod 11, so as to press the lower wall of the mounting plate 1 and improve the fixing effect.
