[0003] After the cabinet is installed, it needs to be connected to the power grid for use. The common wiring scheme at present is to open an incoming wire hole at the bottom of the cabinet, and directly extend the cable of the power grid into the cabinet from the incoming wire hole and connect it to the external terminal block in the cabinet. Since the cabinet needs to protect the internal equipment, the incoming wire opening hole opened at the bottom of the cabinet is usually small, and the cable to be connected has different specifications, different cable bending radii, and different degrees of softness and hardness, so different operation spaces are required. In addition, the ground exists, and the operation space below the cabinet is small, so it is difficult for the construction personnel to lead the wire into the cabinet. If the size of the incoming wire hole is enlarged, dust is easy to enter the cabinet, reducing the protection effect of the cabinet. Therefore, the application provides a new technical scheme.

[0019] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The present application will be further described in detail.

[0020] An embodiment of the present application discloses a wire hole 3 assembly structure suitable for external wiring of a cabinet.

[0021] Referring to Figure 1 The wire hole 3 assembly structure suitable for external wiring of a cabinet comprises an incoming hole 1 provided on the bottom surface of the cabinet, a wiring baffle 2 covering the incoming hole 1, and a fixing mechanism provided on the wiring baffle 2. The wiring baffle 2 is horizontally located in the cabinet. In the embodiment, the shape of the incoming hole 1 is rectangular and the corners are rounded. It should be noted that the size of the incoming hole 1 in the embodiment is larger than that of the existing hole, and the area of the wiring baffle 2 is larger than that of the incoming hole 1. The wiring baffle 2 covers the incoming hole 1 directly above, so that the wiring baffle 2 abuts against the inner side wall of the bottom surface of the cabinet. The wiring baffle 2 is provided with a plurality of wire holes 3, and each wire hole 3 is in communication with the incoming hole 1. The fixing mechanism is detachably connected to the incoming hole 1 of the cabinet, so that the wiring baffle 2 can be fixed and covered on the incoming hole 1.

[0022] Through the above arrangement, in actual operation, the wiring baffle 2 is first detached from the cabinet, then the external power cable is passed through the incoming hole 1 of the cabinet and the wire hole 3 of the wiring baffle 2, and then connected to the power interface in the cabinet. Finally, the wiring baffle 2 is reinstalled and fixed on the cabinet body. Since the incoming hole 1 is relatively large, it is convenient for the staff to insert the cable into the incoming hole 1 from the bottom of the cabinet. In addition, the wiring baffle 2 is located inside the cabinet, thereby utilizing the space inside the cabinet to facilitate the cable to pass through the wire hole 3 of the wiring baffle 2, which can solve the problem of insufficient vertical wiring space. Moreover, the operation originally needed to be performed below the cabinet is directly placed inside the cabinet, which is simple and has high visualization, so as to effectively improve the efficiency of the on-site construction personnel, and also achieve the effect of dust prevention.

[0023] The fixing mechanism comprises a baffle 4, a screw rod 5 and a stopper 6. The baffle 4 is arranged on the side of the wiring baffle 2 facing the incoming hole 1 and is parallel to the wiring baffle 2. A rubber pad is attached to the side of the baffle 4 facing the wiring baffle 2. The screw rod 5 is vertically arranged and penetrates the center of the wiring baffle 2. The upper end of the screw rod 5 extends out of the upper surface of the wiring baffle 2 and is welded with a knob for easy rotation. The lower end of the screw rod 5 extends below the wiring baffle 2 and penetrates the center of the baffle.

[0024] The stopper 6 is fixed to the side of the wiring baffle 2 facing the incoming hole 1 and is parallel to the screw rod 5. The length of the baffle 4 is greater than the width of the incoming hole 1 and less than the length of the incoming hole 1. When the length direction of the baffle 4 is perpendicular to the length direction of the incoming hole 1, one end of the baffle abuts against the stopper 6.

[0025] Therefore, when the wire harness is passed through the incoming hole 1 from the bottom of the cabinet and then passed through the wire hole 3 of the wiring baffle 2, the wiring baffle 2 needs to be fixed and covered on the incoming hole 1. At this time, the screw rod 5 can be twisted first to rotate the baffle 4 driven by the screw rod 5, adjust the angle of the baffle 4, so that the baffle can pass through the incoming hole 1, and the baffle 4 is located below the bottom surface of the cabinet. When it is rotated to abut against the stopper 6, the baffle cannot continue to rotate due to the limiting of the stopper 6. Since the baffle is threadedly connected with the screw rod 5, the baffle 4 will continue to move upward under the condition of continuing to rotate the screw rod 5 and the limiting of the stopper 6. Finally, the upper surface of the baffle 4 abuts against the outer side wall of the bottom surface of the cabinet, so that the wiring baffle 2 abuts against the inner side wall of the bottom surface of the cabinet, the wiring baffle 2 is fixed, and the wiring operation is completed.

[0026] When the wiring baffle 2 needs to be removed, the screw rod 5 is reversed, the baffle 4 will rotate with it, then the baffle 4 will abut against the stopper 6 to stop rotating, and the baffle will move downward by continuing to rotate the screw rod 5, and finally separate from the bottom surface of the cabinet, and finally remove the wiring baffle 2.

[0027] In order to prevent the baffle from being separated from the screw rod 5, a limiting block 10 is threadedly connected to the lower end of the screw rod 5 and is arranged on the side of the baffle away from the wiring baffle 2, so as to prevent the baffle 4 from moving out of the screw rod 5. In this embodiment, the limiting block 10 can be a nut.

[0028] In order to enhance the dustproof effect of the wiring baffle 2, sealing cotton 7 is attached to the side edge of the wiring baffle 2 facing the incoming hole 1, so that the sealing cotton 7 can be pressed against the inner side wall of the bottom surface of the cabinet under the action of the baffle 4.

[0029] In order to be compatible with different cables and easy to operate, the sizes of the wire passing holes 3 are different. In this embodiment, some of the wire passing holes 3 are circular holes for cables with small wire diameters, and some of the wire passing holes 3 are elliptical holes for cables with large wire diameters.

[0030] In another embodiment of the present application, the fixing mechanism comprises a fixing rod 8, a locking block 9 and a limiting block 10. The fixing rod 8 longitudinally slides through the wire blocking plate 2, and the upper end of the fixing rod 8 extends to the upper surface of the wire blocking plate 2. The locking block 9 is above the wire blocking plate 2 and is threadedly sleeved on the upper end of the fixing rod 8. The lower end of the fixing rod 8 extends below the wire blocking plate 2 and into the wire inlet opening 1 of the cabinet. The limiting block 10 is horizontally arranged, and the upper surface of the limiting block 10 is welded to the lower end of the fixing rod 8. The length of the limiting block 10 is greater than the width of the wire inlet opening 1 and less than the length of the wire inlet opening 1. By rotating the fixing rod 8, the angle of the limiting block 10 is adjusted so that the limiting block 10 can pass through the wire inlet opening 1. Then, the fixing rod 8 is rotated and pulled so that the upper surfaces of both ends of the limiting block 10 can abut against the outer side wall of the bottom surface of the cabinet. By rotating the locking block 9, the locking block 9 is moved downward, and finally the lower surface of the locking block 9 abuts against the upper surface of the wire blocking plate 2, so that the wire blocking plate 2 covers the wire inlet opening 1 and abuts against the inner side wall of the bottom surface of the cabinet.

[0031] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
