Therefore, other examples of the exemplary embodiments may have different values, and it should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in the subsequent drawings.

[0050] Embodiment 1:

[0051] This embodiment provides a wire fixing device for electrical engineering construction, including a mounting seat 14, and also includes:

[0052] A mounting ring 1, wherein the mounting ring 1 is fixedly disposed on a mounting seat 14, and an opening for inserting electric wires is provided on the mounting ring 1;

[0053] A closed ring 2, which is slidably disposed in the mounting ring 1 and is used to close the opening of the mounting ring 1. The closed ring 2 also has an opening;

[0054] A sliding assembly, wherein the closed ring 2 is slidably arranged in the mounting ring 1 through the sliding assembly;

[0055] Fixing assembly: after the closing ring 2 closes the opening of the mounting ring 1, the position of the closing ring 2 is fixed by the fixing assembly.

[0056] In the technical solution, when the wire needs to be fixed, the mounting seat 14 is first fixed on the wall according to the position to be fixed. Since the closed ring 2 is slidably arranged in the mounting ring 1 through the sliding assembly, the closed ring 2 is first slid, the opening of the closed ring 2 is made to correspond to the opening of the mounting ring 1, and then the wire is put into the opening, and then the closed ring 2 is slid, and the opening of the closed ring 2 is rotated toward the opposite side, so that the body of the closed ring 2 closes the opening of the mounting ring 1.

[0057] After the main body of the closing ring 2 closes the opening of the mounting ring 1, the position of the closing ring 2 and the mounting ring 1 can be fixed by a fixing assembly, thereby fixing the opening of the mounting ring 1, so that the wire will not be separated from the mounting ring 1 and the closing ring 2, and the wire will always be located in the inner circle of the mounting ring 1 and the closing ring 2.

[0058] With this structural design, if the wrong wire is selected and the wire needs to be replaced, it is only necessary to release the position fixation of the closed ring 2, and then move the closed ring 2 so that the opening of the closed ring 2 is rotated again to correspond to the opening of the installation ring 1, so that the opening of the installation ring 1 becomes vacant, and the original wire can be taken out from the vacant opening for replacement, avoiding the need to remove all wire cards when the wire needs to be replaced.

[0059] Embodiment 2:

[0060] This embodiment provides a wire fixing device for electrical engineering construction, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0061] Furthermore, the sliding assembly includes:

[0062] A T-shaped bar 3, which is fixed to the inner circle of the mounting ring 1 and is bent in an arc;

[0063] A T-slot 4, wherein the T-slot 4 is arranged in an arc on the outer ring of the closed ring 2, the outer ring diameter of the closed ring 2 matches the inner ring diameter of the mounting ring 1, and the T-slot 4 matches the T-bar 3;

[0064] The arc trajectory axes of the T-bar 3 and the T-slot 4 are coaxial with the axes of the inner ring of the closed ring 2 and the inner and outer rings of the mounting ring 1 , and the closed ring 2 is slidably arranged on the inner ring of the mounting ring 1 through the cooperation of the T-bar 3 and the T-slot 4 .

[0065] In the present technical solution, since the arc trajectory axes of the T-shaped bar 3 and the T-shaped slot 4 are coaxial with the axes of the inner ring of the closed ring 2 and the inner and outer rings of the mounting ring 1, the closed ring 2 is slidably arranged on the inner ring of the mounting ring 1 through the cooperation of the T-shaped bar 3 and the T-shaped slot 4, so that the closed ring 2 can slide through the cooperation of the T-shaped bar 3 and the T-shaped slot 4. After the closed ring 2 slides, the opening of the closed ring 2 can be rotated about the axis of the closed ring 2, thereby achieving the purpose of moving the opening of the closed ring 2;

[0066] When the opening of the closed ring 2 moves to correspond to the opening of the mounting ring 1, an opening will appear in the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1, and the wire can be inserted through the opening. When the opening of the closed ring 2 moves to completely correspond to the inner ring of the mounting ring 1, the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1 will not have an opening, so that the wire body is completely covered in the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1.

[0067] Through this structural design, the arrangement of the T-shaped bar 3 and the T-shaped slot 4 makes the sliding of the closed ring 2 smoother, and facilitates the sliding of the closed ring 2 in the mounting ring 1 to drive the opening of the closed ring 2 to rotate about the axis of the closed ring 2, thereby achieving the effect of opening and closing the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1.

[0068] Embodiment 3:

[0069] This embodiment provides a wire fixing device for electrical engineering construction, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0070] Furthermore, the fixing assembly includes:

[0071] A pressing plate 5, wherein the pressing plate 5 is located outside the mounting ring 1;

[0072] A positioning column 6, wherein the positioning column 6 is fixedly arranged at the lower end of the pressing plate 5, the positioning column 6 is movably arranged on the mounting ring 1, and one end of the positioning column 6 protrudes from the inner side surface of the mounting ring 1;

[0073] A positioning hole 7, wherein the closed ring 2 is provided with a positioning hole 7 matching the positioning column 6;

[0074] A driving assembly, used for pressing the pressing plate 5 downwards;

[0075] The pressing plate 5 and the mounting ring 1 are fixedly connected via a spring sleeved on the positioning column 6 .

[0076] In the present technical solution, after the wires are put in, it is necessary to drive the inner ring of the closed ring 2 and the inner ring of the mounting ring 1 to form a closed cavity, and then when it is necessary to fix the position of the closed ring 2 to avoid a gap in the cavity, the pressing plate 5 is pulled outward, so that the pressing plate 5 drives the positioning column 6 to move upward, so that the end of the positioning column 6 protruding from the inner side of the mounting ring 1 is retracted into the mounting ring 1, and then the closed ring 2 is slid, so that the end of the closed ring 2 with the positioning hole 7 rotates with the axis of the closed ring 2 as the axis;

[0077] After the positioning hole 7 is rotated to correspond to the positioning column 6, the pressure plate 5 is released. Since the pressure plate 5 and the mounting ring 1 are fixedly connected by the spring sleeved on the positioning column 6, after the pressure plate 5 is released, the pressure plate 5 will be reset by the resilience of the spring, driving the positioning column 6 to reset downward, so that one end of the positioning column 6 protrudes from the inner side of the mounting ring 1 again, so that the positioning column 6 enters the positioning hole 7 of the closed ring 2, thereby fixing the position of the closed ring 2 by inserting the positioning column 6 into the positioning hole 7 of the closed ring 2 to prevent the closed ring 2 from sliding. At this time, the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1 will also be closed, thereby fixing the position of the closed ring 2 to prevent the closed ring 2 from deviating.

[0078] Then, the pressing plate 5 is pressed by the driving assembly to prevent one end of the positioning column 6 from being positioned in the positioning hole 7 of the closed ring 2, thereby fixing the position of the positioning column 6 and preventing the positioning column 6 from being separated from the positioning hole 7 of the closed ring 2.

[0079] Through this structural design, by setting the pressure plate 5, the positioning column 6 and the positioning hole 7, when the closed ring 2 slides to the cavity formed by the inner ring of the closed ring 2 and the inner ring of the mounting ring 1 and is closed, the positioning hole 7 of the closed ring 2 will correspond to the positioning column 6 of the mounting ring 1, so that the position of the closed ring 2 is fixed by the cooperation of the positioning column 6 and the positioning hole 7, avoiding the closed ring 2 from shifting and causing the cavity to open.

[0080] Embodiment 4:

[0081] This embodiment provides a wire fixing device for electrical engineering construction, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0085] A driving ring 9, wherein the driving ring 9 is spirally arranged on the fixing bolt 8, and the driving ring 9 is located between the lower end surface of the screw head of the fixing bolt 8 and the outer surface of the closing ring 2;

[0086] When the positioning hole 7 corresponds to the positioning column 6 , one side of the lower surface of the driving ring 9 is arranged corresponding to the upper surface of the pressing plate 5 .

[0087] The outer ring of the driving ring 9 has concave and convex patterns.

[0088] In the present technical solution, after the electric wire is placed in the cavity and the position of the closed ring 2 is positioned, the fixing bolt 8 can be screwed in so that the screw end of the fixing bolt 8 moves toward the electric wire, so that the screw end of the fixing bolt 8 presses the electric wire tightly to prevent the electric wire from moving, thereby achieving a better fixing effect on the electric wire;

[0089] After the fixing bolt 8 has tightened the wire, it is necessary to press the pressure plate 5 downward to fix the position of the positioning column 6, and then the driving ring 9 can be screwed. The driving ring 9 moves downward on the fixing bolt 8 through threaded transmission. Since the positioning hole 7 corresponds to the positioning column 6, one side of the lower surface of the driving ring 9 is set corresponding to the upper surface of the pressure plate 5, so that after the driving ring 9 moves downward on the fixing bolt 8, the lower surface of the driving ring 9 will be set in conflict with the upper surface of the pressure plate 5, and then continue to screw the driving ring 9, the pressure plate 5 can be pressed downward by the conflict between the driving ring 9 and the pressure plate 5, so as to fix the position of the positioning column 6.

[0090] Through this structural design, the setting of the fixing bolt 8 makes it convenient to put the wire into the cavity and position the closed ring 2. By screwing in the fixing bolt 8, the screw end of the fixing bolt 8 can be moved toward the wire and pressed, so that the fixing effect of the wire is better. The setting of the driving ring 9 makes it convenient to press the pressure plate 5 downward, thereby fixing the position of the positioning column 6.
