[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0030] Referring to Figures 1-3 , an embodiment provided by the present utility model: A new type of building electrical wiring duct fixing device includes a fixing module 1. A through hole 15 is opened on the front surface of the fixing module 1. A first clamping plate 4 is fixedly connected to the inner wall of the through hole 15. A shallow groove 16 is opened on the inner wall of the through hole 15. The first clamping plate 4 and the shallow groove 16 are respectively on the upper inner wall and the lower inner wall of the through hole 15. An extrusion spring 13 is fixedly connected to the inner wall of the shallow groove 16. The top end of the extrusion spring 13 is fixedly connected to a second clamping plate 5. The first clamping plate 4 is pressed by the extrusion spring 13 and closely adheres to the second clamping plate 5. A plurality of convex blocks 9 are fixedly connected to the outer surface of the fixing module 1. A plurality of grooves 8 are opened on the outer surface of the fixing module 1. A plurality of limiting columns 14 are fixedly connected to both ends of the through hole 15. The limiting columns 14 are used to limit the front and back movement of the second clamping plate 5. A fixing base 2 slides on the outer surface of the fixing module 1. The fixing module 1 and the fixing base 2 are connected through the cooperation of the convex blocks 9 and the grooves 8.

[0031] Referring to Figure 2 , Figure 3, an embodiment provided by the present utility model: a placement groove one 10 is formed on the lower surface of the clamping plate one 4, and a placement groove two 11 is formed on the upper surface of the clamping plate two 5. The cavity formed by the two placement grooves is used to place the power cable. The shapes of the clamping plate one 4 and the clamping plate two 5 are trapezoidal. The trapezoidal inclined surfaces of the two clamping plates are for facilitating the insertion of the cable into the interior of the clamping plates. A spherical groove 7 is formed on the inner surface of the groove 8, and the spherical groove 7 is used to hold the ball 6. A clamping groove 17 is formed on the upper surface of the convex block 9. One end of a spring 12 is fixedly connected to the inner wall of the clamping groove 17, and the other end of the spring 12 is fixedly connected to the ball 6. The ball 6 slides on the inner wall of the clamping groove 17 and is stuck in the clamping groove 17 and cannot pop out. The ball 6 can be held on the inner wall of the spherical groove 7 through the spring 12 to clamp the fixing module 1 and the fixing base 2, or the fixing module 1 can be forced to break away from the clamping of the ball 6.

[0032] Referring to Figure 1 , Figure 2 , Figure 4 , an embodiment provided by the present utility model: multiple groups of the convex blocks 9 are provided, and the multiple groups of the convex blocks 9 are symmetrically arranged with the center line of the fixing module 1 as the axis of symmetry. Multiple groups of the grooves 8 are provided, and the multiple groups of the grooves 8 are symmetrically arranged with the center line of the fixing module 1 as the axis of symmetry. Multiple fixing modules 1 can be connected and fixed to each other. The outer surface of the convex block 9 slides on the inner wall of the groove 8. The connection mode between the fixing module 1 and the fixing base 2 is realized through the convex block 9 and the groove 8. The shape of the fixing base 2 is L-shaped, and the L-shape can fix the fixing module 1 more firmly. A convex block 9 is fixedly connected to the upper surface of the fixing base 2, and a groove 8 is formed on the inner surface of the fixing base 2. The convex blocks 9 and the grooves 8 of the fixing module 1 and the fixing base 2 are the same. The shape of the through hole 15 is square, and the outer surface of the clamping plate two 5 is slidably connected to the inner wall of the through hole 15. The clamping plate two 5 is limited by the limiting column 14 and can only slide up and down on the inner wall of the through hole 15. Multiple fixing holes 3 are formed on the outer surface of the fixing base 2, and the fixing holes 3 are openings for fixing the fixing base 2 with bolts or nails, etc.

[0033] Working principle: When in use, the staff can first fix the fixed base 2 at the required installation position through the fixing holes 3, pass the power cable through the cavity formed by the placing groove one 10 and the placing groove two 11. Both clamping plates are provided with inclined surfaces to facilitate the insertion of one or more power cables. At this time, the clamping plate two 5 is pushed downwards, and the upward elastic force of the compression spring 13 clamps the power cable at the same time. Then, the fixing module 1 is slidably connected to the fixed base 2 through the cooperation of the groove 8 and the convex block 9. Because of the cooperation of the ball 6 and the spherical groove 7, the fixing module 1 and the fixed base 2 are fixed. When more power cables need to be fixed, multiple fixing modules 1 can be connected to each other. At this time, if there are too many connections between the fixing modules 1, the fixed base 2 may become loose and it is necessary to add a fixed base 2. Since the installation of the fixed base 2 requires the removal of the fixing module 1, before installing the fixed base 2, the fixing modules 1 can be connected in advance. The fixed base 2 is only half-connected to the fixing module 1. At this time, a fixing hole 3 will be exposed on the fixed base 2. After fixing, the other half is exposed for fixing. When a new cable needs to be added to the power cable that has already been installed, there is no need to reinstall it. Only one or more fixing modules 1 need to be added on the original basis, which is convenient for the modification and maintenance of the power cable.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
