At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0027] like Figure 1 - Figure 5 As shown, the embodiment of the utility model provides a line fixing device for a power distribution box, comprising: a base 2, which is a rectangular block structure, a wire fixing groove 21 is provided on the top of the base 2, the wire fixing groove 21 has a U-shaped structure in radial section, and is open at the top, and is used to place the cable 7, a movable groove 22 is provided on one side of the wire fixing groove 21, and an inner cavity 23 is provided on one side of the base 2, and is used to place other components of the fixing device;

[0028] The cover plate 3 is fixedly connected to one side of the base 2 and is used to cover the inner cavity 23 to prevent the components inside the inner cavity 23 from being affected by external environmental factors and becoming ineffective;

[0029] The wire fixing assembly 4 is an integrally formed structure, comprising a pressure rod 41 and a vertical plate 43 which are arranged perpendicular to each other. A rotating shaft 42 is provided at the connection between the pressure rod 41 and the vertical plate 43. The pressure rod 41 and the vertical plate 43 are rotatably connected inside the movable groove 22 through the rotating shaft 42. One end of the rotating shaft 42 is fixedly connected to a connecting column 46 through a bent rod 45, and the bent rod 45 and the connecting column 46 are located inside the inner cavity 23. One end of the bent rod 45 close to the rotating shaft 42 is arranged parallel to the pressure rod 41, and the other end is bent toward a side away from the vertical plate 43, and is arranged to fit the bottom contour of the wire fixing groove 21 when close to the wire fixing groove 21.

[0030] The fixing column 5 is fixed inside the inner cavity 23 and connected to the connecting column 46 via a tension spring 6. The fixing column 5 is configured to pull the pressure rod 41 toward the bottom of the wire fixing groove 21 and press the cable 7 inside the wire fixing groove 21 when contracted.

[0031] The cable fixing assembly 4 is provided to cooperate with the cable fixing groove 21 to clamp and fix the cable 7, and the tension of the tension spring 6 is used to achieve automatic locking, which is convenient to operate and improves work efficiency.

[0032] like Figure 2 As shown, the cover plate 3 and the base 2 are detachably connected, including but not limited to bolts or snap-on fixation, which facilitates the disassembly and maintenance of the internal parts of the inner cavity 23; a through groove 31 is opened on the cover plate 3, and the through groove 31 has the same radial cross-sectional shape as the wire fixing groove 21, which facilitates the passage of the cable 7.

[0033] like Figure 3 As shown, it also includes a shift block 44 which is vertically fixedly connected to the vertical plate 43 and is arranged parallel to the pressure rod 41 . The shift block 44 protrudes from the top of the movable groove 22 .

[0034] By providing the shifting block 44 , it is convenient to manually rotate the pressing rod 41 and the vertical plate 43 by shifting the shifting block 44 , so that the pressing rod 41 is flipped and moved upward and flush with the side wall of the wire fixing groove 21 , thereby opening the wire fixing groove 21 .

[0035] like Figure 3 As shown, a gasket 47 is provided at the bottom of the pressure rod 41 . The gasket 47 is made of flexible rubber material to increase the friction force on the cable 7 and improve the fixing effect of the cable 7 .

[0036] The rotating shaft 42 protrudes from both sides of the pressure rod 41 and the vertical plate 43, and is rotatably connected with the two side walls opposite to the movable groove 22. Two rotating holes symmetrically arranged on the two side walls of the movable groove 22 are rotatably connected with the rotating shaft 42, among which the rotating hole close to the inner cavity 23 connects the movable groove 22 and the inner cavity 23.

[0037] like Figure 1 As shown, it also includes a base plate 1, which is fixed inside the wiring box by bolts. A plurality of linearly arranged bases 2 are fixedly connected to the top of the base plate 1, and each base 2 is closely arranged, so as to achieve fixed wiring of multiple cables 7.

[0038] In the technical solution provided by the utility model, in the initial state, under the tension of the tension spring 6, the connecting column 46 and the fixing column 5 are close to each other, at this time, the bending rod 45 drives the wire fixing assembly 4 to rotate as a whole, the pressing rod 41 flips into the wire fixing groove 21, and presses down close to the bottom of the wire fixing groove 21, while the vertical plate 43 is in a vertical state, and the shifting block 44 is located in the area above the movable groove 22.

[0039] When the cable 7 needs to be fixed, the block 44 is manually moved toward the side of the movable groove 22. At this time, the wire fixing assembly 4 rotates as a whole, and the connecting column 46 is driven away from the fixed column 5 through the bent rod 45 to resist the tension of the tension spring 6 and make the tension spring 6 deform and stretch until one side of the vertical plate 43 abuts against the bottom of the movable groove 22. At this time, the pressure rod 41 is flush with the side wall of the wire fixing groove 21, so that the top of the wire fixing groove 21 is completely open (refer to Figure 4 ); Then put the cable 7 into the top of the wire fixing groove 21, and arrange the cable 7 so that it is close to the bottom of the wire fixing groove 21, then release the finger that is moving the dial block 44, the tension spring 6 is reset and shortened, and the connecting column 46 is pulled close to the fixing column 5, and then the wire fixing assembly 4 is pulled to rotate as a whole through the bent rod 45. At this time, the pressure rod 41 is turned toward the inside of the wire fixing groove 21 until the gasket 47 at the bottom abuts against the top of the cable 7. At this time, the tension spring 6 is not completely reset, and a continuous pulling force is applied to the bent rod 45, and the pressure rod 41 cooperates with the bottom wall of the wire fixing groove 21 to clamp and fix the cable 7 (refer to Figure 5 ).

[0040] When removing the wires, it is only necessary to move the shifting block 44 to open the limit of the pressing rod 41 at the top of the wire fixing groove 21. The operation is simple and no other auxiliary tools are required.

[0041] It is particularly noted that the device can clamp cables 7 of different diameters, and the diameter of the clampable cable 7 only needs to be no greater than the top width of the cable fixing groove 21 or less than half of the groove width.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
