[0032] Figure 1 is a top view of a fixing device for cable installation provided by an embodiment of the present disclosure. Figure 2 is a front view of a fixing device for cable installation provided by an embodiment of the present disclosure. As Figure 1 、 2As shown, the fixing device includes: a housing 10, two clamping components 20, a control component, and a locking component. The two clamping components 20, the control component, and the locking component are all located inside the housing 10;

[0033] Figure 3 is Figure 1 a provided AA cross-sectional view. As Figure 3 shown, the control component includes a first sliding shaft 31, a fixed block 32, a rotating shaft 33, two first elastic members 34, and two flexible ropes 35. Both ends of the first sliding shaft 31 are connected to the inner wall of the housing 10. The fixed block 32 is sleeved outside the first sliding shaft 31. One end of the rotating shaft 33 is rotatably installed on the fixed block 32, and the rotation center line of the rotating shaft 33 is perpendicular to the first sliding shaft 31.

[0034] As Figure 3 shown, both of the two clamping components 20 are used to clamp a cable. Both of the two clamping components 20 are movably sleeved outside the first sliding shaft 31, and the fixed block 32 is located between the two clamping components 20. Both ends of one flexible rope 35 are respectively connected to one clamping component 20 and the rotating shaft 33, and both ends of the other flexible rope 35 are respectively connected to the other clamping component 20 and the rotating shaft 33. Both ends of one first elastic member 34 are respectively connected to one clamping component 20 and the fixed block 32, and both ends of the other first elastic member 34 are respectively connected to the other clamping component 20 and the fixed block 32.

[0035] Among them, the locking component has a first state and a second state. When the locking component is in the first state, the locking component is connected to the two clamping components 20 and locks the relative positions of the two clamping components 20. When the locking component is in the second state, the locking component is separated from the two clamping components 20.

[0036] The fixing device for cable installation provided by the embodiments of the present disclosure is provided with two clamping components 20, a control component and a locking component in the housing 10. Among them, the control component includes a first sliding shaft 31, a fixing block 32, a rotating shaft 33, two first elastic members 34 and two flexible ropes 35. The first sliding shaft 31 is fixed in the housing 10, and the fixing block 32 and the two clamping components 20 are both sleeved on the first sliding shaft 31. A rotatable rotating shaft 33 is further provided at one end of the fixing block 32, and two flexible ropes 35 are further connected to the rotating shaft 33, and the two flexible ropes 35 are respectively connected to the two clamping components 20. In this way, when the rotating shaft 33 is twisted, the flexible ropes 35 can be wound around the rotating shaft 33, and the two flexible ropes 35 will drag the two clamping components 20 to approach the fixing block 32, that is, the two clamping components 20 are made to approach each other. When the positions of the two clamping components 20 are adjusted to the appropriate positions, the locking component is adjusted to the first state to lock the relative positions of the two clamping components 20. In this way, during butt joint installation, the two clamping components 20 respectively clamp the two cables, and after adjusting the clamping components 20 to the appropriate positions, the relative positions of the clamping components 20 are locked by the locking component, so that the positions of the two cables to be butted can be kept fixed, thereby avoiding the problem of inaccurate cable butt joint, reducing the installation difficulty of the staff, and improving the electrical construction efficiency. And, after the cable butt joint is completed, the locking component is adjusted to the second state, and the two clamping components 20 are controlled to reset by the two first elastic members 34 for subsequent use.

[0037] Exemplarily, in the embodiments of the present disclosure, the flexible rope 35 can be a steel wire rope. The steel wire rope has a certain flexibility and good stability, meets the requirement of being wound around the rotating shaft 33 and can improve the wear resistance of the flexible rope 35.

[0038] Figure 4 is Figure 2 A BB cross-sectional view is provided. As Figure 4 shown, the clamping component 20 includes a sliding plate 21, a threaded rod 22, a threaded sleeve 23, a gear 24, a first guide rod 25, a first clamp 26 and a second clamp 27.

[0039] As Figure 3 、 4 shown, the sliding plate 21 is movably sleeved outside the first sliding shaft 31. The plate surface of the sliding plate 21 has a first groove 211 and a second groove 212 which are distributed at intervals. Both the first groove 211 and the second groove 212 penetrate through the sliding plate 21. The threaded rod 22 is movably inserted into the sliding plate 21. One end of the threaded rod 22 is located in the first groove 211 and is coaxially connected to the gear 24 in the first groove 211. The other end of the threaded rod 22 is located in the second groove 212 and is inserted into the threaded sleeve 23. The threaded rod 22 is threadedly connected to the threaded sleeve 23.

[0040] Figure 5 isFigure 4 A partial enlarged view of part C is provided, as Figure 4 、 5 shown. The first clamp 26 and the second clamp 27 are both located in the second groove 212. The first clamp 26 is fixed on the groove wall of the second groove 212. One end of the first guide rod 25 is connected to the first clamp 26, and the other end of the first guide rod 25 is movably inserted into the second clamp 27. The first guide rod 25 is parallel to the threaded rod 22, and the second clamp 27 is connected to the end of the threaded sleeve 23 away from the threaded rod 22.

[0041] Figure 6 is Figure 4 A partial enlarged view of part D is provided. As Figure 3 、 6 shown, the control assembly further includes a rack 38. The rack 38 is parallel to the first sliding shaft 31. The two ends of the rack 38 are respectively connected to the inner wall of the housing 10. The rack 38 is inserted into the first groove 211 and meshes with the gear 24.

[0042] In the above implementation, the flexible rope 35 is connected to the sliding plate 21. In this way, under the traction of the flexible rope 35, the sliding plate 21 can be dragged to slide relative to the first sliding shaft 31. At the same time, a gear 24 is coaxially provided at the end of the threaded rod 22 of the clamping assembly 20, and the gear 24 meshes with the rack 38. Therefore, when the rotating shaft 33 rotates to wind the flexible rope 35 and the flexible rope 35 drags the sliding plate 21, the gear 24 will rotate relative to the fixed rack 38, thereby driving the threaded rod 22 to rotate together with the gear 24.

[0043] The other end of the threaded rod 22 is connected to the threaded sleeve 23, and the second clamp 27 is connected to the threaded sleeve 23. Due to the limitation of the first guide rod 25 between the first clamp 26 and the second clamp 27, the second clamp 27 cannot rotate relative to the first clamp 26, and the first clamp 26 is fixed in the second groove 212. Therefore, under the combined action of the threaded rod 22 and the threaded sleeve 23, the second clamp 27 will axially move up and down along the threaded rod 22, so as to achieve the purpose of approaching or separating from the first clamp 26 and complete the clamping action of the cable.

[0044] In the embodiment of the present disclosure, during the process of turning the rotating shaft 33 to adjust the position of the clamping assembly 20, the first clamp 26 and the second clamp 27 also automatically complete the clamping operation of the cable. In this way, there is no need for technicians to manually adjust, realizing the automation of cable docking, clamping and position adjustment, which is convenient to use and can effectively improve the efficiency of cable docking and installation.

[0045] Optionally, as Figure 4 shown, both the first clamp 26 and the second clamp 27 can be semi-circular clamps. After the two semi-circular clamps are butted, they enclose a through hole for the cable to pass through.

[0046] Exemplarily, as Figure 4 shown, the side of the sliding plate 21 has an opening 213 extending to the second groove 212. By providing the opening 213 on the side of the sliding plate 21 to communicate the opening 213 with the second groove 212, it is convenient to place the cable into the two clamps in the second groove 212 to realize the clamping of the cable.

[0047] Optionally, as Figure 3 shown, the locking assembly includes: a pushing member 41 and a locking plate 42. The locking plate 42 is perpendicular to the threaded rod 22. The locking plate 42 is located between the inner wall of the housing 10 and the sliding plate 21. The pushing member 41 connects the locking plate 42 and the inner wall of the housing 10. The pushing member 41 is used to control the locking plate 42 to move away from or close to the sliding plate 21.

[0048] In the embodiment of the present disclosure, the locking plate 42 is located between the bottom of the housing 10 and the sliding plate 21. A limiting sliding groove is respectively provided on two opposite side walls in the housing 10. The two ends of the locking plate 42 are respectively slidably arranged in the corresponding limiting sliding grooves. In this way, the sliding direction of the locking plate 42 is limited by the limiting sliding grooves to prevent the locking plate 42 from being skewed during the sliding process.

[0049] In one implementation manner, the surface of the locking plate 42 facing the sliding plate 21 has a locking groove, and the side of the sliding plate 21 facing the locking plate 42 has a locking protrusion.

[0050] When the pushing member 41 pushes the locking plate 42 to move towards the sliding plate 21 and makes the locking groove on the locking plate 42 cooperate with the locking protrusion on the sliding plate 21, at this time the locking plate 42 is connected to the two sliding plates 21 and locks the relative positions of the two sliding plates 21 to prevent the two sliding plates 21 from loosening easily.

[0051] When the pushing member 41 drives the locking plate 42 to move away from the sliding plate 21 and the locking groove on the locking plate 42 is separated from the locking protrusion on the sliding plate 21, at this time the locking plate 42 is separated from the two sliding plates 21, and the two sliding plates 21 are released and can be reset under the elastic force of the first elastic member 34.

[0052] In another implementation manner, the surface of the locking plate 42 facing the sliding plate 21 has a locking protrusion, and the side of the sliding plate 21 facing the locking plate 42 has a locking groove.

[0053] When the pushing member 41 pushes the locking plate 42 to move towards the sliding plate 21 and makes the locking protrusion on the locking plate 42 cooperate with the locking groove on the sliding plate 21, at this time the locking plate 42 is connected to the two sliding plates 21 and locks the relative positions of the two sliding plates 21 to prevent the two sliding plates 21 from loosening easily.

[0054] When the pushing member 41 drives the locking plate 42 to move away from the sliding plate 21, and the locking protrusion of the locking plate 42 is separated from the locking groove on the sliding plate 21, at this time, the locking plate 42 is separated from the two sliding plates 21, and the two sliding plates 21 are released and can be reset under the elastic force of the first elastic member 34.

[0055] Exemplarily, as Figure 3 shown, the pushing member 41 includes a pushing screw rod. One end of the pushing screw rod is rotatably inserted into the locking plate 42, and one end of the pushing screw rod is axially fixed to the locking plate 42. The other end of the pushing screw rod penetrates through the housing 10, and the other end of the pushing screw rod is threadedly connected to the housing 10.

[0056] In the above implementation, the pushing screw rod is threadedly connected to the housing 10, and one end of the pushing screw rod is inserted into the locking plate 42 inside the housing 10, and the other end of the pushing screw rod is located outside the housing 10, so that technicians can turn the pushing screw rod outside the housing 10.

[0057] Exemplarily, a limiting disk is provided at one end of the pushing screw rod inserted into the locking plate 42. The limiting disk is movably arranged in the groove inside the locking plate 42, and the opening 213 of the groove is smaller than the diameter of the limiting disk. This enables the pushing screw rod to be movably inserted into the locking plate 42 and not fall off from the locking plate 42.

[0058] Optionally, as Figure 2 、 3 shown, the fixing device further includes a third fixture 51, a fourth fixture 52, a second guide rod 53 and a telescopic member 54.

[0059] As Figure 3 、 4 shown, in the axial direction of the rotating shaft 33, the third fixture 51 is located between the fourth fixture 52 and the sliding plate 21. The third fixture 51 is connected to the inner wall of the housing 10. One end of the first guide rod 25 is connected to the third fixture 51. The other end of the second guide rod 53 is movably inserted into the fourth fixture 52, and the second guide rod 53 is parallel to the threaded rod 22.

[0060] Wherein, the telescopic member 54 is used to control the fourth fixture 52 to move away from or close to the third fixture 51 along the axial direction of the second guide rod 53.

[0061] In the embodiment of the present disclosure, the side surface of the first fixture 26 facing the sliding plate 21 has a groove for inserting the sliding plate 21, and the groove extends along the axial direction of the first sliding shaft 31, so that the sliding plate 21 will slide along the extension of the groove to avoid the problem of skew during the movement of the sliding plate 21.

[0062] In the above implementation, the third clamp 51 and the fourth clamp 52 are used to place the cables that have been butt-jointed and installed, that is, the cables that have been butt-jointed and installed in the first clamp 26 and the second clamp 27 can be temporarily stored in the third clamp 51 and the fourth clamp 52 .

[0063] Exemplarily, the telescopic member 54 includes a telescopic screw, one end of which is rotatably inserted into the fourth clamp 52, and one end of the telescopic screw is axially fixed to the fourth clamp 52, and the other end of the telescopic screw passes through the shell 10, and the other end of the telescopic screw is threadedly connected to the shell 10.

[0064] In the above implementation, the telescopic screw is threadedly connected to the shell 10, and one end of the telescopic screw is inserted into the fourth clamp 52 in the shell 10, and the other end of the telescopic screw is located outside the shell 10, so that the technician can screw the telescopic screw outside the shell 10.

[0065] For example, a limiting plate is provided at one end of the telescopic screw rod inserted into the fourth clamp 52, and the limiting plate is movably arranged in a groove in the fourth clamp 52, and the opening 213 of the groove is smaller than the diameter of the limiting plate. In this way, the telescopic screw rod can be movably inserted into the fourth clamp 52 and will not fall off from the fourth clamp 52.

[0066] Alternatively, if Figure 4 As shown, the third clamp 51 and the fourth clamp 52 can both be half-ring clamps, and the two half-ring clamps are butt-jointed to form a through hole for the cable to pass through.

[0067] Alternatively, if Figure 3 As shown, the control component also includes two second elastic members 36. In the axial direction of the first sliding shaft 31, the two first elastic members 34 are located between the two second elastic members 36. The two ends of one second elastic member 36 are respectively connected to a clamping component 20 and the inner wall of the shell 10, and the two ends of the other second elastic member 36 are respectively connected to the other clamping component 20 and the inner wall of the shell 10.

[0068] By providing the second elastic member 36 and using the first elastic member 34 and the second elastic member 36 to hold both sides of the clamping assembly 20, the clamping assembly 20 can be prevented from being easily loosened. Elastic members are provided on both sides of the clamping assembly 20 to facilitate rapid resetting of the clamping assembly 20.

[0069] For example, Figure 3 As shown, the first elastic member 34 and the second elastic member 36 are both springs, and the first elastic member 34 and the second elastic member 36 are both sleeved on the first sliding shaft 31 .

[0070] Alternatively, if Figure 4As shown, the control component further includes a second sliding shaft 37. The second sliding shaft 37 is parallel to the first sliding shaft 31. Both ends of the second sliding shaft 37 are connected to the inner wall of the housing 10. The fixing block 32 and the two clamping components 20 are both sleeved outside the second sliding shaft 37.

[0071] Exemplarily, as Figure 4 shown, there are two second sliding shafts 37. The two second sliding shafts 37 are arranged on both sides of the first sliding shaft 31. In this way, by sleeving the clamping component 20 on both the first sliding shaft 31 and the second sliding shaft 37 at the same time, it can be avoided that the clamping component 20 rotates around the first sliding shaft 31 during the sliding process, improving the reliability.

[0072] Optionally, as Figure 1 、 2 shown, the fixing device further includes an ear plate 55. The ear plate 55 is located on the outer wall surface of the housing 10. In the embodiment of the present disclosure, the ear plate 55 is used to install bolts so as to facilitate the installation of the fixing device on a tabletop or a wall surface.

[0073] Exemplarily, as Figure 1 、 2 shown, there are two ear plates 55 on the outer wall surface of the housing 10. The two ear plates 55 can be symmetrically distributed on both sides of the housing 10.

[0074] The usage process of the fixing device for cable installation provided in the embodiment of the present disclosure is as follows:

[0075] First, place the two cables between the first clamp 26 and the second clamp 27 of the two clamping components 20 respectively; then rotate the rotating shaft 33, so that the rotation of the shaft 33 drives the two symmetrically distributed flexible ropes 35 to wind around the shaft 33, and drives the two symmetrically distributed sliding plates 21 to approach the fixing block 32, making the spring in a compressed state. When the two symmetrically distributed sliding plates 21 move towards the middle, since the gear 24 is meshed with the rack 38, the gear 24 is driven to rotate. The rotation of the gear 24 drives the threaded rod 22 to rotate, and the rotation of the threaded rod 22 drives the threaded sleeve 23 to move upward. The upward movement of the threaded sleeve 23 drives the second clamp 27 to move upward. The upward movement of the second clamp 27 cooperates with the first clamp 26 to clamp the cable and move towards the direction of the fixing block 32, completing the clamping and positioning functions.

[0076] When the two cables move to the installation position, the push screw can be rotated to make the push screw move upward and push the locking plate 42 upward. When the locking plate 42 moves upward to contact the two sliding plates 21, the two symmetrically distributed sliding plates 21 can be fixed on the locking plate 42. Then, the technician can perform butt joint installation on the two cables to complete the butt joint installation of the cables.

[0077] Finally, loosen the push screw. Due to the elastic force of the spring, the two sliding plates 21 are pushed back to their original positions, and the first clamp 26 and the second clamp 27 are separated. Then, take out the cable from the first clamp 26 and the second clamp 27 and place it into the third clamp 51 and the fourth clamp 52. Repeat the above steps and wait for multiple bundles of cables to gather in the third clamp 51 and the fourth clamp 52. Then, tighten the telescopic screw to drive the third clamp 51 and the fourth clamp 52 to dock and compress the multiple bundles of cables to complete the docking installation operation of the cables.
