Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0030] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The utility model provides a snap-on cable duct in the cable room of a ring main unit. Figure 1 and Figure 2 As shown, it includes a wire slot seat 10 fixed on the ring network cabinet, and a wire slot cover 20 is installed on the wire slot seat 10. The wire slot cover 20 is installed on the wire slot seat 10 to form a channel for the power line to pass through, thereby achieving the effect of bundling the wires.

[0032] Specifically, in the present embodiment, the cross-section of the wire trough seat 10 is similar to a C-shape, and the wire trough cover 20 covers the opening of the wire trough seat 10 to form a channel. Correspondingly, in other embodiments, the cross-section of the wire trough cover 20 can also be designed to be similar to a C-shape. In this case, the wire trough seat 10 is installed in cooperation with the opening of the wire trough cover 20, and a channel can also be formed. The structures of the wire trough seat 10 and the wire trough cover 20 can be freely selected according to actual needs.

[0033] In order to stably install the wire trough cover 20 on the wire trough seat 10, a plurality of evenly distributed long strip mounting holes 11 are opened on the wire trough seat 10, and buckles are provided at positions corresponding to the mounting holes 11 on the wire trough cover 20, and the buckles are hung on the mounting holes 11 to achieve a locking effect.

[0034] Specifically, in this embodiment, the buckle is hung on the mounting hole 11 to realize the connection between the wire trough seat 10 and the wire trough cover 20. When in use, the buckle is first passed through the corresponding mounting hole 11, and then the wire trough cover 20 is slid so that the side of the mounting hole 11 enters into the buckle, so that the buckle is clamped on the mounting hole 11, thereby realizing the connection between the wire trough seat 10 and the wire trough cover 20.

[0035] like Figure 1As shown, after the buckle is hooked on the mounting hole 11 , in order to prevent the buckle from sliding relative to the mounting hole 11 and causing the buckle to move out of the mounting hole 11 , a locking piece is provided on the wire slot seat 10 to prevent the wire slot cover 20 from sliding relative to the wire slot seat 10 .

[0036] The locking piece includes a bolt, and a threaded hole 12 is provided on the wire trough cover 20, and a bolt is installed on the threaded hole 12 through a thread. Specifically, when the wire trough cover 20 needs to be moved downward to clamp the buckle on the mounting hole 11, the wire trough seat 10 opens a threaded hole 12 at a position corresponding to the upper end of the wire trough cover 20. By tightening the bolt on the threaded hole 12, the upper end of the wire trough cover 20 can be limited, so that the wire trough cover 20 cannot move upward relative to the wire trough cover 10, thereby making the buckle stably clamped in the mounting hole 11; similarly, if it is necessary to move upward to clamp the buckle on the mounting hole 11, the threaded hole 12 is opened at the lower end position corresponding to the wire trough cover 20 to limit the lower end of the wire trough cover 20.

[0037] like Figure 1 and Figure 2 As shown, both ends of the wire trough seat 10 are provided with a first flange 13, a mounting hole 11 is opened on the first flange 13, a second flange 21 is provided at the position of the wire trough cover 20 corresponding to the first flange 13, and a buckle is provided on the second flange 21. In other embodiments, a buckle can be provided on the wire trough seat 10, and a mounting hole 11 can be opened on the wire trough cover 20, which can be selected according to actual needs.

[0038] First embodiment:

[0039] In this embodiment, if Figure 2 and Figure 4 As shown, the buckle is an L-shaped bracket 30 , wherein an opening is formed between the L-shaped bracket 30 and the side of the second flange 21 for hanging the wire trough cover 20 on the mounting hole 11 .

[0040] In order to make the L-shaped bracket 30 hang on the mounting hole 11 more stably, the inner end of the opening formed by the L-shaped bracket 30 and the second flange 21 is narrowed. When the L-shaped bracket 30 is hung on the mounting hole 11, due to the effect of the narrowing, the L-shaped bracket 30 will undergo a certain deformation when it is completely hung on the mounting hole 11, so that the connection between the L-shaped bracket 30 and the mounting hole 11 is more stable.

[0041] like Figure 5As shown, the inner end of the opening formed by the L-shaped bracket 30 is arc-shaped, and two opposite first protrusions 31 are arranged at both ends of the arc. The first protrusion 31 has a smooth transition, and the side of the mounting edge 11 corresponding to the L-shaped bracket 30 has a first cylinder 32 adapted to the arc shape of the inner end of the opening. During use, the L-shaped bracket is first passed through the corresponding mounting hole 11, and the L-shaped bracket 31 moves downward. The side of the first cylinder 31 contacts the first protrusion 31, and then the first cylinder 31 slowly opens the L-shaped bracket 30 until the first cylinder 32 enters the inner end of the opening to achieve clamping. The first protrusion 31 achieves a limiting effect, thereby preventing the L-shaped bracket 30 from falling off from the mounting hole 11 by itself, thereby ensuring the stable use of the device.

[0042] Second embodiment:

[0043] In this embodiment, if Figure 3 and Figure 6 As shown, the buckle is a T-shaped bracket 40, wherein the T-shaped bracket 40 and the side of the second flange 21 form two openings, so that the wire trough cover 20 can be moved upward to be hung, and can also be moved downward to be hung, which is more convenient to use.

[0044] In order to make the T-shaped bracket 40 hang on the mounting hole 11 more stably, the two open inner ends formed by the T-shaped bracket 40 and the second flange 21 are both shrunk. When the T-shaped bracket 40 is hung on the mounting hole 11, due to the effect of the shrinkage, the T-shaped bracket 40 will undergo a certain deformation when it is completely hung thereon, thereby making the connection between the T-shaped bracket 40 and the mounting hole 11 more stable.

[0045] Correspondingly, such as Figure 7 and Figure 8 As shown, the inner ends of the two openings formed by the T-shaped bracket 40 are both arc-shaped, and two opposite second protrusions 41 are provided at both ends of the arc. The second protrusions 41 have a smooth transition, and the corresponding two side edges of the mounting hole 11 are provided with second cylinders 42 that are adapted to the arc shape of the inner ends of the openings. The second cylinders 42 are used in conjunction with the corresponding openings to ensure that the connection between the T-shaped bracket 40 and the mounting hole 11 is more stable.

[0046] In this embodiment, if Fig. 9As shown, when one side of the T-shaped bracket 40 is opened for a long time, one end of the T-shaped bracket 40 will slowly tilt up, causing the opening on one side to become larger and the opening on the other side to become smaller. When the wire trough cover 20 is removed for line maintenance, when the wire trough cover 20 is reinstalled on the wire trough seat 10, if the side with the larger opening is continued to be used, the clamping force may be insufficient and it is easy to fall off. At this time, it can be moved to the other side so that the side with the smaller opening cooperates with the mounting hole 11. Due to its smaller opening, it can be clamped more tightly during the clamping, so that the connection between the wire trough cover 20 and the wire trough seat 10 is tighter. Correspondingly, the next time the wire trough cover 20 is removed and reinstalled, the tilting direction of the T-shaped bracket 40 is opposite. Therefore, each time the wire trough cover 20 is reinstalled, it is only necessary to select the side with the smaller opening to clamp with the mounting seat 11, thereby ensuring that the device can stably connect the wire trough seat 10 and the wire trough cover 20 each time, thereby improving the stability of the device.

[0047] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
