Description

Technical Field

[0001] This utility model relates to the field of low-voltage distribution box technology, specifically a locking structure for a low-voltage integrated distribution box. Background Technology

[0002] A low-voltage integrated distribution box is a low-voltage power distribution device that integrates functions such as power distribution, control, protection, and monitoring. It is widely used in industrial plants, residential communities, commercial buildings, municipal facilities, and other places, and is a key component of low-voltage power distribution networks.

[0003] The locking blocks of existing low-voltage integrated distribution boxes gradually age after long-term use, making them unable to open. In addition, the disassembly method is too cumbersome and the installation location makes replacement extremely difficult. Furthermore, when workers inspect the inside of the distribution box, the box door has no fixing device, which causes the box door to rotate due to natural wind during maintenance, thus affecting the maintenance workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a locking structure for low-voltage integrated distribution boxes, which has the advantages of easy replacement of lock blocks and secure door fixing, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a locking structure for a low-voltage integrated distribution box, comprising a box body, a box door rotatably connected to the outer wall of the box body, an extension rod fixedly installed on the outer wall of the box body, a fixing block fixedly installed on the outer wall of the box door, a magnetic block one fixedly installed on the inner wall of the fixing block, a locking block slidably connected to the inner wall of the box door, a magnetic block two slidably connected to the inner wall of the extension rod, a threaded column fixedly installed on the outer wall of the magnetic block two, a rotating ring rotatably connected to the inner wall of the extension rod, a sliding frame slidably connected to the inner wall of the box door, a threaded rod rotatably connected to the inner wall of the box door, a pressure block fixedly installed at the bottom of the sliding frame, a rack fixedly installed on the outer wall of the sliding frame, a gear rotatably connected to the inner wall of the box door, a locking plate fixedly installed at the bottom of the pressure block, and a locking groove formed at the top of the locking block.

[0006] As a preferred technical solution of this utility model: the shape of the second magnetic block is adapted to the inner wall of the extension rod, and the outer wall of the second magnetic block is in contact with the inner wall of the extension rod.

[0007] As a preferred technical solution of this utility model: the threaded post passes through the rotating ring, and the threaded post and the rotating ring are connected by threads.

[0008] As a preferred technical solution of this utility model: the S pole of the first magnetic block and the N pole of the second magnetic block are arranged opposite to each other, and the positions of the first magnetic block and the second magnetic block correspond to each other.

[0009] As a preferred technical solution of this utility model: the threaded rod passes through the sliding frame, and the threaded rod and the sliding frame are connected by a thread.

[0010] As a preferred technical solution of this utility model: the number of the sliding frame, the pressure block and the rack is two, and the two sliding frames and the pressure block are symmetrically arranged on the inner wall of the box door, and the two racks are respectively located on both sides of the gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This locking structure for low-voltage integrated distribution boxes works by rotating a threaded rod, which in turn moves the sliding frame through its threaded connection with the sliding frame. This movement in turn causes the sliding frame to move the pressure block and rack. The movement of the rack causes the gear to rotate, which in turn causes the racks on both sides to move the sliding frames and pressure blocks on both sides to move to both sides simultaneously. This causes the locking plates on the outside of the pressure blocks on both sides to separate from the locking grooves. At this point, the locking block's fixing relationship disappears, and the locking block can be replaced.

[0012] 2. The locking structure used in the low-voltage integrated distribution box works by rotating the box door, causing magnetic block one and magnetic block two to come into contact, thus attracting magnetic block one and fixing the box door. After maintenance is completed, rotating the rotating ring causes the threaded column to move through the threaded connection between the rotating ring and the threaded column, which in turn causes magnetic block two to move, so that magnetic block two and magnetic block one are no longer in contact. At this time, the box door can be rotated to close. Attached Figure Description

[0015] 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.

[0016] Please see Figure 1 - Figure 6 A locking structure for a low-voltage integrated distribution box includes a box body 1, a box door 2 rotatably connected to the outer wall of the box body 1, an extension rod 3 fixedly installed on the outer wall of the box body 1, a fixing block 4 fixedly installed on the outer wall of the box door 2, a magnetic block 5 fixedly installed on the inner wall of the fixing block 4, a locking block 6 slidably connected to the inner wall of the box door 2, a magnetic block 7 slidably connected to the inner wall of the extension rod 3, a threaded column 8 fixedly installed on the outer wall of the magnetic block 7, a rotating ring 9 rotatably connected to the inner wall of the extension rod 3, a sliding frame 10 slidably connected to the inner wall of the box door 2, a threaded rod 11 rotatably connected to the inner wall of the box door 2, a pressure block 12 fixedly installed at the bottom of the sliding frame 10, a rack 13 fixedly installed on the outer wall of the sliding frame 10, a gear 14 rotatably connected to the inner wall of the box door 2, a locking plate 16 fixedly installed at the bottom of the pressure block 12, and a locking groove 15 opened at the top of the locking block 6.

[0017] In the above structure, the shape of the locking plate 16 is adapted to the locking groove 15, so that after the locking plate 16 enters the inner wall of the locking groove 15, the locking groove 15 is fixed by the locking plate 16, thereby fixing the locking block 6.

[0018] In a preferred embodiment, the shape of the second magnetic block 7 is adapted to the inner wall of the extension rod 3, and the outer wall of the second magnetic block 7 is in contact with the inner wall of the extension rod 3.

[0019] In the above structure, the magnetic block 7 is attached to the inner wall of the extension rod 3, so that the outer wall of the magnetic block 7 is always attached to the inner wall of the extension rod 3 when the magnetic block 7 moves, thus preventing the magnetic block 7 from rotating when it moves.

[0020] In a preferred embodiment, the threaded post 8 passes through the rotating ring 9, and the threaded post 8 and the rotating ring 9 are threadedly connected.

[0021] In the above structure, by rotating the rotating ring 9, the rotating ring 9 drives the threaded column 8 to move through the threaded connection with the threaded column 8, which in turn drives the external magnetic block 7 to move.

[0022] In a preferred embodiment: the S pole of magnetic block 5 is arranged opposite to the N pole of magnetic block 7, and the positions of magnetic block 5 and magnetic block 7 correspond to each other.

[0023] In the above structure, the positions of magnetic block 7 and magnetic block 5 correspond so that when the door 2 rotates, it drives the fixing block 4 and the locking block 6 to rotate, which in turn causes the fixing block 4 to drive the internal magnetic block 5 to rotate, thus causing magnetic block 5 and magnetic block 7 to come into contact. At this time, the relative arrangement of the S pole of magnetic block 5 and the N pole of magnetic block 7 causes magnetic block 5 and magnetic block 7 to attract each other, thereby fixing the door 2 and preventing the door 2 from rotating.

[0024] In a preferred embodiment, the threaded rod 11 passes through the sliding frame 10, and the threaded rod 11 and the sliding frame 10 are threadedly connected.

[0025] In the above structure, by rotating the threaded rod 11, the threaded rod 11 drives the sliding frame 10 to move through the threaded connection with the sliding frame 10, which in turn drives the external pressure block 12 and rack 13 to move.

[0026] In a preferred embodiment, there are two sliding frames 10, two pressure blocks 12 and two racks 13, and the two sliding frames 10 and pressure blocks 12 are symmetrically arranged on the inner wall of the door 2, and the two racks 13 are located on both sides of the gear 14.

[0027] In the above structure, when the sliding frame 10 moves, the sliding frame 10 drives the external pressure block 12 and rack 13 to move. At this time, the meshing of the rack 13 and gear 14 drives the gear 14 to rotate, which in turn drives the rack 13 on the other side to move. This causes the two racks 13 to drive the two pressure blocks 12 and the sliding frame 10 to move relative to or opposite to each other.

[0028] Working Principle: When inspecting internal components, unlocking the locking block 6 disengages the locking mechanism of the door 2. Rotating the door 2 causes the fixing block 4 and magnetic block 5 to rotate, moving magnetic block 5 to the outside of magnetic block 7. The relative arrangement of the S pole of magnetic block 5 and the N pole of magnetic block 7 causes them to attract each other, thus fixing the door 2 and preventing it from rotating due to natural wind, which would affect the maintenance workers. After maintenance, rotating the rotating ring 9 causes it to move through its threaded connection with the threaded post 8. This, in turn, moves the external magnetic block 7, causing the magnetic block to... The separation of magnetic block 7 from magnetic block 5 creates a distance between them, thus eliminating the fixed relationship of magnetic block 5. When it is necessary to replace the locking block 6, the threaded rod 11 is rotated, causing the sliding frame 10 to move through the threaded connection between the threaded rod 11 and the sliding frame 10. This causes the sliding frame 10 to move the external pressure block 12 and rack 13. The meshing of the rack 13 and gear 14 causes the gear 14 to rotate, which in turn causes the rack 13 on the other side to move. This causes the two racks 13 to move the two pressure blocks 12 and the sliding frame 10, thus causing the locking plates 16 outside the two pressure blocks 12 to disengage from the locking grooves 15 on the upper and lower sides of the locking block 6. This eliminates the fixed relationship of the locking block 6, at which point the locking block 6 can be replaced.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
