[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

"Inside and outside" refer to the inside and outside of the outline of the corresponding component. In addition, it should be noted that the terms used, such as "first, second", etc., are intended to distinguish one element from another and do not have order and importance. In addition, in the description with reference to the accompanying drawings, the same mark in different drawings represents the same element. The above definitions are only used to explain and illustrate the present disclosure and should not be construed as limitations on the present disclosure.
[0030] For ease of understanding, please refer to the attached Figures 1 to 6 , the specific structure and working principle of the cable fixing device disclosed in the present invention are explained in detail with reference to the embodiments.
[0031] The present disclosure relates to a cable fixing device, which can fix a cable extending along a first direction. Figure 1 , the first direction is the vertical direction. In this embodiment, the cable fixing device includes a first clamp 1 and a second clamp 2. A first connecting surface 11 is provided on the first clamp 1. The first connecting surface 11 can be located on one side of the first clamp 1. A first placement groove 12 and a connecting protrusion 13 are provided on the first connecting surface 11, and the first placement groove 12 passes through the first clamp 1 along the first direction. A second connecting surface 21 is provided on the second clamp 2. The second connecting surface 21 can also be provided on one side of the second clamp 2. The second connecting surface 21 is arranged opposite to the first connecting surface 11, so that the first clamp 1 and the second clamp 2 can be connected through the two connecting surfaces. A second placement groove 22 and a connecting groove 23 are provided on the second connecting surface 21, and the second placement groove 22 also passes through the second clamp 2 along the first direction. The first clamp 1 and the second clamp 2 can be rectangular, and the first connecting surface 11 and the second connecting surface 12 can be arranged on two opposite sides of the rectangle. Of course, the first clamp 1 and the second clamp 2 can be other shapes, which can be determined according to actual conditions, such as the location where the cable 3 needs to be installed and the external environment, etc. The present disclosure does not limit this.
[0032] When the cable 3 needs to be fixed in the cable fixing device, the cable 3 can be first placed in the first placement groove 12 on the first clamp 1, and then the second clamp 2 and the first clamp 1 are aligned with each other, so that the second placement groove 22 on the second clamp 2 can cooperate with the first placement groove 12 on the first clamp 1, and the cable 3 is clamped in the cable fixing device. At this time, the connecting protrusion 13 can also be synchronously inserted into the connecting groove 23, so that the second clamp 2 is fixedly connected to the first clamp 1, so that the cable 3 can be stably located in the cable fixing device.
[0033] The cable fixing device of the present disclosure can clamp the cable 3 between the first clamp 1 and the second clamp 2 through the first placement groove 12 and the second placement groove 22. The first placement groove 12 and the second placement groove 22 can be arc-shaped, for example, the first placement groove 12 and the second placement groove 22 are semicircular, and the two sides of the cable 3 are clamped by mutual cooperation, and the semicircular first placement groove 12 and the second placement groove 22 can also wrap the cable 3 completely, thereby improving the stability of the cable 3 in the first clamp 1 and the second clamp 2. Of course, in other embodiments, the first placement groove 12 and the second placement groove 22 can also be other shapes, as long as they can ensure that the cable 3 located between the two is clamped. The specific shape can be determined according to the actual situation, and the present disclosure does not limit this.
[0034] In one embodiment of the present disclosure, Figure 1The first placement groove 12 and the second placement groove 22 enclose a placement hole 7, and an insulating sleeve 71 is arranged in the placement hole 7. When the cable 3 needs to be fixed, the insulating sleeve 71 can be first installed to the corresponding position of the cable 3, and then the cable 3 is placed in the first placement groove 12 of the first clamp 1, and then the second clamp 2 and the first clamp 1 are matched, so that the first placement groove 12 and the second placement groove 22 can enclose a placement hole 7 to fix the cable 3. By setting the insulating sleeve 71, the wear of the first clamp 1 and the second clamp 2 on the cable 3 can be reduced, so that the first clamp 1 and the second clamp 2 will wear the insulating sleeve 71, and when the insulating sleeve 71 is damaged, it can be replaced to avoid the first clamp 1 and the second clamp 2 damaging the insulation skin of the cable 3, causing leakage, and then causing a safety accident.
[0035] In one embodiment of the present disclosure, see Figure 1 , anti-skid patterns 8 are provided in the first placement groove 12 and the second placement groove 22. In the present embodiment, the anti-skid patterns 8 are semicircular protrusions provided in the first placement groove 12 and the second placement groove 22. When the first clamp 1 and the second clamp 2 clamp the cable 3, the anti-skid patterns 8 can increase the friction of the cable 3 in the first placement groove 12 and the second placement groove 22, reduce the movement of the cable 3 in the first placement groove 12 and the second placement groove 22, and improve the stability of the cable 3. Of course, in other embodiments, the anti-skid patterns 8 can also be other shapes, such as dot-shaped protrusions, stripes, etc., which can be determined according to actual conditions, and the present disclosure does not limit this.
[0036] In one embodiment of the present disclosure, see Figure 2 and Figure 3 In this embodiment, the connection groove 23 is located on the second connection surface 21 and extends a certain distance along the first direction, and does not penetrate the second clamp 2. A first connection hole 24 is provided in the connection groove 23. The first connection hole 24 extends along the first direction, one end of which penetrates the top surface of the connection groove 23, and the other end extends a certain distance along the first direction. A second connection hole 14 matching with the first connection hole 24 is provided on the connection protrusion 13, and the second connection hole 124 penetrates the connection protrusion 13. When the first clamp 1 and the second clamp 2 are matched with each other and need to be fixedly connected, the connection protrusion 13 is located in the connection groove 23, and the first connection hole 24 and the second connection hole 14 are also aligned with each other. At this time, it is only necessary to insert the first tightening bolt 4 from the second connection hole 14, and the first tightening bolt 4 penetrates the connection protrusion 13 through the second connection hole 14, and then screw into the second clamp 2 through the first connection hole 24, so as to complete the fixed connection between the first clamp 1 and the second clamp 2.
[0037] In one embodiment of the present disclosure, see Figure 2 and Figure 3In this embodiment, the side wall of the connection groove 23 located on the second connection surface 21 is an arc-shaped wall, and the connection protrusion 13 is an arc-shaped protrusion that protrudes from the first connection surface 11 and cooperates with the arc-shaped wall. In this way, when the connection protrusion 13 enters the connection groove 23, it will not get stuck in the connection groove 23, and the arc-shaped connection groove 23 and the connection protrusion 13 are also safer, which can prevent the staff from scratching when installing the cable fixing device. Of course, in other embodiments, the connection groove 23 and the connection protrusion 13 can also be other shapes, such as rectangular, or triangular, etc., which can be determined according to actual conditions, and the present disclosure does not limit this.
[0038] In one embodiment of the present disclosure, see Figures 1 to 3 , the first clamp 1 and the second clamp 2 are formed into an elongated structure extending along a second direction perpendicular to the first direction, and a plurality of connecting protrusions 13, connecting grooves 23, and first placement grooves 12 and second placement grooves 22 are provided, and are arranged alternately along the second direction. In this embodiment, the first direction is a vertical direction, and the second direction is a horizontal direction. Four connecting protrusions 13 and connecting grooves 23, and three first placement grooves 12 and second placement grooves 22 are provided on the first clamp 1 and the second clamp 2, respectively. Such an arrangement enables more cables 3 to be connected to the cable fixing device. For example, in this embodiment, the cable fixing device can fix three cables 3, and the connecting grooves 23 and connecting protrusions 13 are alternately provided between the cables 3, so that the mutual fixation between the first clamp 1 and the second clamp 2 can be better completed. In addition, the first clamp 1 and the second clamp 2 can also extend a certain distance along the first direction, so that the first clamp 1 and the second clamp 2 have a certain thickness in the first direction, so that the cables 3 can be better fixed. Of course, in other embodiments, more or fewer first placement grooves 12 and second placement grooves 22, as well as connecting protrusions 13 and connecting grooves 23 may be provided, and the specific number may be determined according to actual conditions, and the present disclosure does not impose any limitation on this.
[0039] In one embodiment of the present disclosure, see Figure 4 and Figure 5 A positioning portion 5 is also provided on the first clamp 1 and the second clamp 2, and the cable fixing device can be positioned and installed at the installation position through the positioning portion 5. For example, when the cable 3 needs to be fixed to a vertical wall, the positioning portion 5 can be located on the side wall of the first clamp 1 or the second clamp 2, so that the entire cable fixing device can be connected to the wall. Or if the cable fixing device needs to be connected between two opposite walls, the positioning portion 5 can also be provided at the four corners of the first clamp 1 and the second clamp 2, so as to complete the fixing of the cable fixing device. Of course, in other embodiments, the positioning portion 5 can also be located at other positions, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0040] In one embodiment of the present disclosure, see Figure 4 , the positioning portion 5 includes a plurality of fixing protrusions 51 arranged at the edges of the first clamp 1 and the second clamp 2, and a connecting hole 51 is arranged in the fixing protrusion 51. A connecting hole 511 is arranged on the fixing protrusion 51, and a second fastening bolt 6 is arranged in the connecting hole 511, and the fixing protrusion 51 can be fixedly connected to the installation position by the second fastening bolt 6. In this embodiment, the first clamp 1 and the second clamp 2 are rectangular, and four fixing protrusions 51 are arranged at the four corners of the first clamp 1 and the second clamp 2 respectively. After the first clamp 1 and the second clamp 2 complete the fixing of the cable 3, the first clamp 1 and the second clamp 2 can be placed at the position to be fixed, and then the second fastening bolt 6 is screwed into the connecting hole 511 to complete the fixing. Of course, in other embodiments, the shapes on the first clamp 1 and the second clamp 2 can also be other, and the number of fixing protrusions 51 can also be other, which can be determined according to actual conditions, and the present disclosure does not limit this.
[0041] In one embodiment of the present disclosure, Figure 5 The positioning portion 5 includes a first buckle 52 disposed on the side of the first clamp 1 and the second clamp 2 and a first slot 53 disposed at the installation position. In this embodiment, the first clamp 1 and the second clamp 2 are rectangular, the first buckle 52 is an L-shaped buckle disposed on one side of the first clamp 1, and a first slot 53 is disposed at the installation position. The first slot 53 can cooperate with the first buckle 52. When fixing, first place the first buckle 52 above the first slot 53 and then move it downward, so that the first buckle 52 can be snapped into the first slot 53, and the fixation is completed. Of course, in other embodiments, the first buckle 52 and the second buckle 53 can be of other shapes and can be located at other positions. The specific shape can be determined according to the actual situation, and the present disclosure does not limit this.
[0042] In one embodiment of the present disclosure, the first clamp 1 and the second clamp 2 are made of insulating wood material. Such an arrangement can first improve the safety of the cable fixing device. The first clamp 1 and the second clamp 2 are made of insulating material, which can improve the safety of the staff during the maintenance process after the cable 3 fails. In addition, the insulating wood material has a lower hardness than the metal material. When the cable 3 is located in the first placement groove 12 and the second placement groove 22, the wear of the first clamp 1 and the second clamp 2 received by the cable 3 can be reduced, thereby reducing the probability of the cable 3 being damaged and increasing the service life of the cable 3.
[0043] When the cable fixing device of the present invention is used, it is first necessary to connect the insulating sleeve 71 to the corresponding position of the cable 3, and then install the cable 3 into the first placement groove 12 of the first clamp 1, and then align the second clamp 2 with the first clamp 1 so that the connecting protrusion 13 on the first clamp 1 and the connecting groove 23 on the second clamp 2 are matched together, and finally screw the first fastening bolt 4 into the first connecting hole 24 and the second connecting hole 14 to complete the mutual fixation between the first clamp 1 and the second clamp 2 and the clamping of the cable 3.
[0044] After that, the cable fixing device needs to be fixedly connected to the installation position. First, the first clamp 1 and the second clamp 2 are placed at the corresponding installation positions, and then the second fastening bolt 6 is screwed into the connection hole 511 of the fixing protrusion 51 to the installation position, and the fixing of the cable fixing device can be completed. The cable fixing device disclosed in the present invention has a simple structure, low manufacturing cost, and has a good fixing effect, can extend the service life of the cable 3 in the cable fixing device, and also has good safety.
