[0021] 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.

[0022] Please see Figures 1 to 7 This utility model provides an integrated distribution box with incoming line protection, including a box body 1 and a box door 2 rotatably connected to the front end of the box body 1. An incoming line sleeve 3 is connected to the side of the box body 1. The incoming line sleeve 3 is provided with multiple incoming line channels 8, which are evenly distributed in the incoming line sleeve 3. The inlet sleeve 3 is connected to a clamping mechanism for clamping multiple wires. The clamping mechanism includes a guide post 13, a connecting cylinder 7, multiple clamping blocks 11, multiple pressing cylinders 12, multiple pressing rods 15, and multiple springs 16. The guide post 13 is used to guide the connecting cylinder 7. The connecting cylinder 7 is movably connected to the inlet sleeve 3. The clamping blocks 11 are movably connected to the inlet sleeve 3 and are connected to the corresponding inlet channel 8. One end of the pressing rod 15 is connected to the clamping block 11, and the other end is inserted into the pressing cylinder 12. Both ends of the springs 16 are connected to the pressing rod 15 and the pressing cylinder 12. The end of the pressing cylinder 12 is connected to the connecting cylinder 7. The inner side of the inlet sleeve 3 is connected to a connecting seat 4 for limiting the position of the connecting cylinder 7.

[0023] After the guide passes through the inlet channel 8, a thrust is applied to the handle 6, driving the connecting cylinder 7 forward. The connecting cylinder 7 applies a thrust to multiple pressing cylinders 12, and the pressing rod 15 drives the clamping block 11 to move. At this time, spring one 16 and spring two 17 are gradually compressed. When the clamping block 11 presses against the wire, the handle 6 is driven to rotate, so that the connecting block 5 connects with the limiting groove 10 in the connecting seat 4, thereby limiting the connecting cylinder 7, preventing the clamping block 11 from loosening, improving the stability of the connection between multiple wires and the inlet sleeve 3, and achieving a good limiting purpose.

[0024] The clamping mechanism also includes a guide block 14 and a second spring 17. The guide block 14 is connected to one end of the guide post 13 and is slidably connected inside the connecting cylinder 7. The two ends of the second spring 17 are connected to the guide block 14 and the connecting cylinder 7. When the connecting cylinder 7 moves forward, the guide block 14 slides inside the connecting cylinder 7, and the connecting cylinder 7 is slidably connected to the inlet sleeve 3, improving the stability of the movement of the connecting cylinder 7.

[0025] The other end of the guide post 13 is fixedly connected to the inlet sleeve 3.

[0026] The end of the pressing rod 15 is connected to the shaft of the pressing block 11, and the end of the pressing cylinder 12 is connected to the shaft of the connecting cylinder 7. When the connecting cylinder 7 moves forward, the included angle between the two connecting cylinders gradually increases, the spring 16 is gradually compressed, the pressing rod 15 and the pressing cylinder 12 slide relative to each other, the spring 16 applies a pushing force to the pressing rod 15, and the pressing rod 15 pushes the pressing block 11 to move, so that the pressing block 11 gradually presses against the wire, which facilitates the simultaneous locking and fixing of multiple wires.

[0027] The pressing rod 15 is slidably connected to the pressing cylinder 12, which improves the stability of the movement of the pressing rod 15.

[0028] A handle 6 is rotatably connected to the end of the connecting cylinder 7, and a connecting block 5 is connected to the outside of the handle 6. The connecting block 5 matches the connecting seat 4.

[0029] The connector 4 is provided with a movable groove 9 and a limiting groove 10. The movable groove 9 is connected to the limiting groove 10, and the limiting groove 10 matches the connector 5. When the wire is in the positioning state, rotating the handle 6 drives the connector 5 to rotate, causing the connector 5 to move toward the movable groove 9. Then, the handle 6 is released, and the compressed spring 17 drives the connector cylinder 7 to move back a small distance, so that the connector 5 connects with the limiting groove 10, thereby limiting the connector 5 and the connector cylinder 7, preventing the clamping block 11 from moving, and improving the stability of the connection between the clamping block 11 and the wire.

[0030] The end of the clamping block 11 is an arc-shaped surface, which can fit better with the wire. The inner side of the wire inlet channel 8 and the arc-shaped surface are friction surfaces, which improve the contact friction with the wire and prevent the wire from slipping.

[0031] Working principle: The wire passes through the inlet channel 8 and connects with the electrical components inside the housing 1. Applying a pushing force to the handle 6 drives the connecting cylinder 7 forward. The connecting cylinder 7 applies a pushing force to multiple pressing cylinders 12, gradually compressing spring 16. Spring 16 then applies a pushing force to the pressing rod 15, which in turn drives the clamping block 11 to move, pressing it against the wire. Simultaneously, the guide block 14 slides within the connecting cylinder 7, gradually compressing spring 17 until the clamping block 11 presses firmly against the wire, achieving synchronous locking and fixing of multiple wires, improving the stability of the connection between the wire and the inlet sleeve 3. Rotating the handle 6 again moves the connecting block 5, positioning it within the movable groove 9. Releasing the handle 6 causes the compressed spring 17 to drive the connecting cylinder 7 back a small distance, connecting the connecting block 5 with the limiting groove 10, thus limiting the connection of the connecting cylinder 7, preventing the clamping block 11 from moving, and improving the stability of the connection between the clamping block 11 and the wire. When the wire needs to be loosened, a pushing force is applied to the handle 6 to separate the connecting block 5 from the limiting groove 10. Then, the handle 6 is rotated to move the connecting block 5 away from the connecting seat 4. Finally, the handle 6 is released, and the compressed spring 17 drives the connecting cylinder 7 to move back. The connecting cylinder 7 drives multiple pressing cylinders 12 to move back, and the pressing rod 15 applies a pulling force to the pressing block 11 to separate the pressing block 11 from the wire, thereby realizing the simultaneous loosening of multiple wires. The operation is simple and convenient.

[0032] 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.
