[0003] The cable is generally fixed to the crossarm by a fixing device to prevent the cable from falling from the crossarm. The existing cable fixing device is a U-shaped clamp, which is used to abut the cable on the crossarm, and then the two ends of the U-shaped clamp are fixed to the crossarm by bolts, thereby achieving the fixation of the cable on the crossarm. However, this method will cause uneven force on the cable, thereby causing local deformation of the cable. Utility Model Content

[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.

[0029] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, vertical" are defined according to the direction of the cable fixture device. Figure 1 In the drawing direction, "inside" and "outside" are defined according to the outline of the corresponding parts. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0030] See also Figures 1 to 6 The cable fixing device provided in the embodiment of the present disclosure may include a first clamp 110, a second clamp 120, a first fastener 310, a first protective layer 410 and a second protective layer 420. The first clamp 110 can be installed on the cross arm 10, and one end of the second clamp 120 can be hinged to the first clamp 110. The connected end of the two can be defined as a hinged end, and the opposite end can be defined as a free end. The first fastener 310 is used to fix the free ends of the first clamp 110 and the second clamp 120. The first fastener 310 can be a threaded fastener. The connection between the first clamp 110 and the second clamp 120 is finally achieved by setting threaded holes, through holes, etc. on the first clamp 110 and the second clamp 120. One side of the first protective layer 410 can be detachably connected to the first clamp 110, and the other side is in an arc shape that is compatible with the cable 20. One side of the second protective layer 420 can be detachably connected to the second clamp 120, and the other side is in an arc shape that is compatible with the cable 20. When the first clamp 110 and the second clamp 120 are tightened, they can be enclosed with the first protective layer 410 to form a clamping cavity 421 for clamping the cable 20.

[0031] In the related art, when the cable fixing device is in use, the cable 20 is locally subjected to force. When the clamping force of the cable fixing device on the cable 20 is small, the cable 20 is easy to fall off the cross arm 10. When the clamping force is large, although the cable 20 can be clamped and fixed, the local part of the cable 20 is easily deformed due to the large clamping force.

[0032] It can be understood that in this embodiment, the first protective layer 410 and the second protective layer 420 are respectively installed on the first clamp 110 and the second clamp 120, and the opposite sides are both in an arc shape that is compatible with the cable 20. By setting the first protective layer 410 and the second protective layer 420, the contact area between the cable fixing device and the cable 20 can be increased. When the pressure is constant, the larger the contact area, the smaller the pressure on each stress point of the cable 20, thereby avoiding local deformation of the cable 20 during the clamping process. By making the cable 20 evenly "clamped" by the protective layer, the uniform force on the cable 20 is ensured, so that the cable fixing device can clamp the cable 20 by applying appropriate clamping force to the cable 20.

[0033] In this embodiment, the first protective layer 410 is detachably connected to the first clamp 110, and the second protective layer 420 is detachably connected to the second clamp 120. Therefore, without changing the sizes of the first clamp 110 and the second clamp 120, different sizes of cables 20 can be adapted and fixed by replacing protective layers, thereby improving the adaptability range of the cable fixing device.

[0034] In one embodiment, see Figures 2 to 6 The first clamp 110 and the second clamp 120 may both be provided with a snap-fit ​​groove 111, and the first protective layer 410 and the second protective layer 420 may both be provided with a protrusion 411, and the protrusion 411 is snap-fitted and connected with the snap-fit ​​groove 111, so that the first protective layer 410 can be detachably mounted on the first clamp 110, and the second protective layer 420 can be detachably mounted on the second clamp 120, so as to facilitate the replacement of the protective layers.

[0035] It is not difficult to understand that when the diameter of the cable 20 changes, the original protective layer can be removed from the clamp, and a protective layer that matches the current diameter of the cable 20 can be installed on the clamp. By replacing protective layers of different sizes, cables 20 of different sizes can be adapted, fixed and clamped.

[0036] Of course, in other embodiments, the first clamp 110 and the second clamp 120 may both be provided with a protrusion 411, and the first protective layer 410 and the second protective layer 420 may both be provided with a snap-fit ​​groove 111; or, the first clamp 110 and the second clamp 120 may both be provided with a protrusion 411 and a snap-fit ​​groove 111, and the first protective layer 410 and the second protective layer 420 may be provided with a snap-fit ​​groove 111 and a protrusion 411 at corresponding positions, and by snap-fitting the protrusion 411 and the snap-fit ​​groove 111, a detachable connection between the protective layer and the clamp may be achieved.

[0037] In one embodiment, see Figures 2 to 6 The number of the engaging grooves 111 can be multiple, and they are arranged at intervals in the circumferential direction on the inner side of the first clamp 110 and the inner side of the second clamp 120, respectively. The engaging grooves 111 can extend in the axial direction. The number of the protrusions 411 can be multiple, and they are arranged one by one corresponding to the multiple engaging grooves 111. The axial direction refers to the axial direction of the hole formed by the clamping cavity 421. By providing multiple engaging grooves 111 and multiple protrusions 411, the protective layer can be stably and reliably installed on the clamp.

[0038] For example, the engaging groove 111 can be configured as a dovetail groove, and the protrusion 411 matches the shape of the dovetail groove, so that after the protrusion 411 is inserted into the engaging groove 111, the protective layer can be stably mounted on the clamp. Figures 3 to 6 The dovetail groove may be provided with a bottom wall, which may provide a certain supporting force for the protrusion 411 of the protective layer to prevent the protective layer from being pulled out of the clamp. For example, when the cable 20 is to pass through the clamping cavity 421 up and down, the cable 20 may be pulled downward by the vertical downward gravity to pull the protective layer relative to the clamp. By setting the bottom wall, a certain upward supporting force is provided for the protrusion 411 to prevent the protective layer from being pulled off the clamp.

[0039] In another embodiment, the first protective layer 410 and the first clamp 110 can be magnetically connected, and the second protective layer 420 and the second clamp 120 can be magnetically connected, and the detachable connection between the protective layer and the clamp can be achieved by the magnetic connection; or, the first protective layer 410 and the second protective layer 420 are both provided with screws, and the first clamp 110 and the second clamp 120 are both provided with threaded holes, and the detachable connection between the protective layer and the clamp is achieved by threaded connection of the threaded rod and the threaded hole, so that without changing the size of the first clamp 110 and the second clamp 120, different sizes of cables 20 can be adapted to be fixed and clamped by replacing protective layers, thereby improving the adaptation range of the cable fixing device.

[0040] In one embodiment, see Figures 1 to 3 ,as well as Figure 5 The joint portion 112 of the first clamp 110 close to the cross arm 10 is formed with a plane to fit onto the cross arm 10. The joint portion 112 is provided with a first mounting hole, and the cross arm 10 is provided with a second mounting hole. The cable fixing device also includes a second fastener 320. The second fastener 320 passes through the second mounting hole and is detachably connected to the hole wall of the first mounting hole. The second fastener 320 is a bolt.

[0041] See also Figures 1 to 6 , the use of the cable fixture may include:

[0042] S610. Use the second fastener 320 to install the first clamp 110 that matches the size of the cable 20 on the preset position of the crossarm 10. The preset position refers to the position where the cable 20 should be installed on the crossarm 10. The user can adjust the position of the first clamp 110 on the crossarm 10 based on actual usage.

[0043] S630 , respectively install the first protective layer 410 and the second protective layer 420 adapted to the cable 20 on the first clamp 110 and the second clamp 120 .

[0044] S650 , placing the cable 20 in the clamping cavity 421 .

[0045] S670 , use the first fastener 310 to fix the ends of the first clamp 110 and the second clamp 120 away from the rotating shaft 500 together.

[0046] Of course, the user can also install the first protective layer 410 and the second protective layer 420 that are compatible with the cable 20 on the first clamp 110 and the second clamp 120 respectively according to his own operating habits, and then install the first clamp 110 at the preset position of the crossarm 10. The operating method here is not specifically limited, as long as the cable 20 can be clamped and fixed at the preset position.

[0047] When using a U-shaped clamp to fix the cable, the user needs to first put the U-shaped clamp across the cable 20, and then let the two legs of the U-shaped clamp pass through the two fixing holes on the cross arm 10 respectively, while pulling the U-shaped clamp to push the cable 20 against the cross arm 10, and finally tighten it with a nut. With this cable fixing device, the first clamp 110 can be fixed on the cross arm 10 in advance, and the cable 20 can be moved into the clamping cavity 421 to tighten the two clamps. There is no need to push the cable while aligning the holes, which is easier to operate and improves the installation efficiency.

[0048] In one embodiment, the number of first mounting holes can be multiple, and the multiple first mounting holes can be spaced apart on the joint 112. The number of second mounting holes and second fasteners 320 can also be multiple, and they are respectively arranged one-to-one corresponding to the multiple first mounting holes, so that the first clamp 110 can be stably and reliably fixed on the crossarm 10.

[0049] In one embodiment, see Figures 1 to 3 ,as well as Figure 5 The cable fixing device also includes a rotating shaft 500. Both the first clamp 110 and the second clamp 120 are provided with through holes. The rotating shaft 500 can pass through the through holes on opposite sides of the first clamp 110 and the second clamp 120 along the axial direction, thereby realizing the hinged connection of the first clamp 110 and the second clamp 120.

[0050] In one embodiment, see Figures 1 to 3 The free end of the first clamp 110 has a first plate surface 113, and the first plate surface 113 is provided with a first hole 1131. The free end of the second clamp 120 has a second plate surface 121, and the second plate surface 121 is provided with a second hole 1211. The first plate surface 113 and the second plate surface 121 can fit together, so that the first clamp 110 and the second clamp 120 are fastened by the first fastener 310 passing through the first hole 1131 and the second hole 1211, thereby ensuring that the cable 20 can be evenly "clamped" by the first protective layer 410 and the second protective layer 420, avoiding local deformation of the cable 20 during the clamping process, and ensuring that the cable 20 is evenly stressed.

[0051] Furthermore, there can be multiple first holes 1131, which are spaced apart on the first plate surface 113; there can be multiple second holes 1211 and first fasteners 310, which are respectively arranged in one-to-one correspondence with the multiple first holes 1131, so that the first clamp 110 and the second clamp 120 can be stably and reliably fixed together.

[0052] In this embodiment, the arc is semicircular. Of course, in other embodiments, one of the two protective layers can be a superior arc and the other inferior arc. When the first protective layer 410 is an inferior arc and the second protective layer 420 is a superior arc, the user can place the cable 20 directly in the arc opening of the first protective layer; if the first protective layer 410 is a superior arc and the second protective layer 420 is an inferior arc, the user needs to axially pass the cable 20 into the arc surface of the first protective layer 410, or use force to radially "press" the cable 20 into the arc opening of the first protective layer 410. No specific regulations are made for the arc shape of a single protective layer here, as long as it is convenient for users to install and fix the cable. The superior arc refers to an arc larger than a semicircle, and the inferior arc refers to an arc smaller than a semicircle.

[0053] It should be understood that in order to avoid damaging the cable 20, the first protective layer 410 and the second protective layer 420 can be made of softer materials. For example, in the present embodiment, the first protective layer 410 and the second protective layer 420 can both be structural members made of rubber material. The rubber material has a certain elasticity, which can buffer the clamping force of the clamp on the cable 20 and avoid "squeezing" the cable 20. The rubber material also has a certain friction damping force, which prevents the cable 20 from being pulled along the extension direction of its trajectory, thereby ensuring that the cable fixing device can clamp and fix the cable 20, thereby enhancing the anti-fall effect of the cable 20.

[0054] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0055] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0056] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
