Description

Technical Field

[0001] This invention belongs to the field of cable installation technology and relates to a cable clamping device for installing double-row cables. Background Technology

[0002] Cables are devices used for transmitting electrical energy or signals, and are mostly composed of several or groups of conductors. Cables play a vital role in our lives, with a wide range of applications, including transmitting telecommunication signals and delivering electricity. During cable installation, adjacent cables are prone to tangling, leading to cable tangling.

[0003] A cable clamping device for installing double-row cables is disclosed in patent document CN214100633U. It includes two cable bodies, a clamping mechanism, a distance adjustment mechanism, and a cleaning mechanism. The clamping mechanism is located between the two cable bodies and includes a sleeve plate and a through groove. The two sleeve plates are respectively fitted onto the outside of the two cable bodies, and the through groove is located on the sleeve plate and penetrates through the sleeve plate. The distance adjustment mechanism is located between the two sleeve plates. This device rotates a handle to drive a second threaded rod and a triangular prism to rotate, causing the first and second threaded rods to rotate simultaneously. This moves the clamping plates to both sides, clamping the cable bodies inside the sleeve plates to achieve cable clamping and prevent tangling. The distance between the two cable bodies can be adjusted by rotating a screw. However, this device has the following problem during use: if the cables become loose and sag, adjacent cables can easily entangle.

[0004] To address the aforementioned problems, this invention proposes a cable clamping device for installing double-row cables. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention proposes a cable clamping device for installing double-row cables.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable clamping device for installing double-row cables, comprising a base plate and a tensioning assembly disposed on the base plate; the tensioning assembly has four components, each including a rotating plate and a limiting wheel for winding the cable; two limiting wheels are rotatably disposed on each rotating plate; sliding holes are provided on the base plate at positions corresponding to the rotating plates; a sliding shaft rotatably connected to the corresponding rotating plate is slidably disposed within the sliding hole; a first driving assembly for driving the sliding shaft to slide is mounted on the base plate; a second driving assembly for rotating the rotating plate is disposed on the sliding shaft.

[0007] Furthermore, two adjacent sliding holes are arranged in a figure-eight shape.

[0008] Furthermore, the first drive assembly includes a first lead screw, which is rotatably mounted on the bottom of the substrate; the slide shaft is fixedly connected to a second slider, which is slidably sleeved on the slide rod; the first lead screw is threadedly connected to the first slider, which is fixedly connected to the slide rod.

[0009] Furthermore, the second drive assembly includes a worm and a worm wheel, the worm wheel being fixedly connected to a rotating plate, the sliding shaft being fixedly connected to a mounting bracket, the worm being rotatably mounted on the mounting bracket, and the worm meshing with the worm wheel.

[0010] Furthermore, the worm gear is fixedly connected to a gear, a receiving groove is provided on the base plate, a rack is slidably disposed in the receiving groove, and the rack moves upward to mesh with the gear; a driving component is installed on the base plate to move the rack up and down.

[0011] Furthermore, the driving component includes a push plate and a hinge rod; the push plate is elastically movable within the receiving groove; one end of the hinge rod is hinged to the push plate, and the other end of the hinge rod is hinged to the rack.

[0012] Furthermore, a mounting groove is provided in the middle of the substrate, one end of the push plate extends into the mounting groove, a push block is movably disposed in the mounting groove, and the push block is provided with an inclined surface that abuts against the push plate; the push block moves in the mounting groove, causing the push plate to move along the receiving groove.

[0013] Furthermore, a second lead screw is rotatably mounted in the mounting slot, and the push block is threadedly connected to the second lead screw.

[0014] Furthermore, the end of the push plate that mates with the push block is arc-shaped.

[0015] Compared with the prior art, the present invention has the following beneficial effects: by moving the tensioning assembly outward, the cable is initially tensioned, and at the same time, the distance between the two cables is increased, avoiding entanglement between the two cables. By rotating the second screw head, the rack and gear mesh, and when the rotating plate moves outward along the sliding hole, the rotating plate rotates outward, the cable is further tensioned, and the cable is further wound onto the limiting wheel. The contact length between the cable and the limiting wheel is increased, thereby making the cable more stably installed on the tensioning assembly and preventing the base plate from sliding along the cable.

[0016] This device is easy to operate and can tighten and fix the cable at the same time, effectively improving the installation efficiency of the cable. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1-8 As shown, the technical solution adopted by the present invention is as follows: A cable clamping device for installing double-row cables includes a base plate 1 and a clamping assembly, wherein the clamping assembly has four components. Each clamping assembly includes a rotating plate 8 and a limiting wheel 9. Two limiting wheels 9 are rotatably mounted on each rotating plate 8, and the limiting wheels 9 are used to wind the cable 25.

[0028] Four sliding holes 6 are provided on the substrate 1, and the four sliding holes 6 correspond one-to-one with the four rotating plates 8. The two adjacent sliding holes 6 are arranged in a figure-eight shape and are symmetrically arranged.

[0029] A sliding shaft 7 is slidably disposed within each sliding hole 6. The rotating plate 8 is rotatably connected to the corresponding sliding shaft 7. A first driving assembly for driving the sliding shaft 7 to slide is mounted on the base plate 1.

[0030] The first drive assembly includes a first lead screw 2. The first lead screw 2 is rotatably mounted on the bottom of the base plate 1. A first screw head 24 is fixedly connected to one end of the first lead screw 2, facilitating rotation of the first lead screw 2. The threads on both sides of the first lead screw 2 have opposite helical directions, and both sides of the first lead screw 2 are threadedly connected to first sliders 3. Each first slider 3 is fixedly connected to a slide rod 4, which is perpendicular to the first lead screw 2. Two second sliders 5 are slidably sleeved on each slide rod 4. The four second sliders 5 correspond one-to-one with four slide shafts 7, and the slide shafts 7 are fixedly connected to the corresponding second sliders 5. The slide shafts 7 move outward along the slide holes 6, with adjacent slide shafts 7 moving away from each other.

[0031] like Figure 7 As shown, when installing cable 25, the sliding shaft 7 is positioned at one end of the sliding hole 6 near the center of the base plate 1, with the four upper limiting wheels 9 on the same straight line and the four lower limiting wheels 9 on the same straight line. Figure 7 As shown, when installing one of the cables 25 between the four upper limit wheels 9, the cable 25 is routed around the outside of the left and right limit wheels 9, and around the inside of the two limit wheels 9 near the middle. Similarly, the other cable 25 is installed on the four lower limit wheels 9.

[0032] Then, the rotating plate 8 is moved outward along the corresponding sliding hole 6, causing adjacent rotating plates 8 to move away from each other and adjacent tensioning components to move away from each other, thus tightening the cable 25 and gradually moving the two cables 25 apart. When the cable 25 is in a certain tension state, the rotating plate 8 is rotated outward around the corresponding sliding shaft 7, further tightening the cable 25, and the cable 25 is further wound onto the limiting wheel 9, increasing the contact length between the cable 25 and the limiting wheel 9. Furthermore, under the limitation of multiple limiting wheels 9, the cable 25 is more stably mounted on the limiting wheel 9, preventing the base plate 1 from sliding along the cable 25.

[0033] A second drive assembly for driving the rotating plate 8 to rotate is mounted on the sliding shaft 7. The second drive assembly includes a worm gear 10 and a worm 13. The sliding shaft 7 is rotatably mounted on the upper end of the sliding shaft 7 and is fixedly connected to the rotating plate 8. A mounting bracket 11 is fixedly connected to the sliding shaft 7, and the worm 13 is rotatably mounted on the mounting bracket 11. When the worm 13 rotates, it drives the worm gear 10 to rotate, thereby causing the rotating plate 8 to rotate around the sliding shaft 7.

[0034] One end of the worm gear 13 is fixedly connected to a rotating shaft 12, and the rotating shaft 12 is fixedly connected to a gear 14. A receiving groove is provided on the base plate 1 at a position corresponding to the sliding hole 6, and a rack 15 that meshes with the gear 14 is arranged vertically within the receiving groove. The rack 15 is arranged parallel to the sliding hole 6. When the rack 15 moves upward and meshes with the gear 14, the sliding shaft 7 slides along the sliding hole 6, and the gear 14 rolls on the rack 15. The gear 14 drives the worm gear 13 to rotate, and the worm gear 13 drives the worm wheel 10 to rotate, thereby causing the rotating plate 8 to rotate outward.

[0035] A driving component is mounted on the base plate 1 to move four racks 15 up and down simultaneously. The driving component includes a push plate 17 and a hinge rod 19. The push plate 17 is slidably disposed in a receiving groove, and a spring 20 is fixedly connected between one end of the push plate 17 and the end wall of the receiving groove. A first clearance groove 16 is formed at the lower end of the racks 15, and a second clearance groove 18 is formed at the upper end of the push plate 17. One end of the hinge rod 19 extends into the second clearance groove 18 and is hinged to the push plate 17, and the other end of the hinge rod 19 extends into the first clearance groove 16 and is hinged to the racks 15. Multiple hinge rods 19 can be provided on each push plate 17.

[0036] In this embodiment, a mounting groove is formed in the middle of the upper surface of the substrate 1, and two push blocks 21 are slidably disposed in the mounting groove. A second lead screw 22 is rotatably mounted in the mounting groove, and the threads on both sides of the second lead screw 22 have opposite helical directions. The two push blocks 21 are respectively threadedly connected to both sides of the second lead screw 22. When the second lead screw 22 rotates, the two push blocks 21 move closer to each other or further away from each other. Each push block 21 has inclined surfaces on both sides. One end of the push plate 17 extends into the mounting groove and abuts against the corresponding inclined surface. A spring 20 is disposed at the end of the push plate 17 away from the mounting groove.

[0037] One end of the second lead screw 22 extends to the outside of the base plate 1 and is fixedly connected to the second screw head 23, which facilitates the turning of the second lead screw 22.

[0038] like Figure 1 As shown, the second lead screw 22 is rotated, which in turn causes the two push blocks 21 to move away from each other. The push blocks 21 push the corresponding push plates 17 through the inclined plane, causing the push plates 17 to move against the elastic force of the spring 20. The push plates 17 push the rack 15 upward through the hinge rod 19, which in turn causes the rack 15 to mesh with the gear 14.

[0039] The end of the push plate 17 that mates with the inclined plane is arc-shaped so that the push plate 17 can slide smoothly along the inclined plane.

[0040] Working principle: Initially, such as Figure 1As shown, the sliding shaft 7 is located at one end of the sliding hole 6 near the middle of the base plate 1. The rack 15 does not mesh with the gear 14. Under the action of the spring 20, the push plate 17 abuts against the corresponding inclined surface. The four limit wheels 9 on the upper side are on the same straight line, and the four limit wheels 9 on the lower side are on the same straight line.

[0041] Install cable 25, such as Figure 7 As shown, one of the cables 25 is installed between the four upper limit wheels 9, with the cable 25 passing over the outside of the two limit wheels 9 at the left and right ends, and passing over the inside of the limit wheel 9 closest to the mounting groove. Similarly, the other cable 25 is installed between the four lower limit wheels 9.

[0042] Rotating the first screw head 24 causes the two first sliders 3 to move away from each other. The first sliders 3 drive the corresponding sliding rods 4 to move outward. Guided by the sliding hole 6, the second slider 5 slides outward along the sliding rod 4, and the sliding shaft 7 moves outward along the sliding hole 6, thereby causing the rotating plate 8 to move outward along the sliding hole 6. The adjacent tensioning components move away from each other, causing the cables 25 to be gradually tightened, while the distance between the cables 25 gradually increases. When the rotating plate 8 moves along the sliding hole 6, the self-locking action between the worm gear 10 and the worm 13 prevents the rotating plate 8 from rotating around the sliding shaft 7.

[0043] When the cable 25 is tensioned to a certain state, the second screw head 23 is rotated, the second lead screw 22 rotates, and the two push blocks 21 move away from each other. The push blocks 21 push the push plate 17, so that the push plate 17 moves against the elastic force of the spring 20. The push plate 17 pushes the rack 15 upward through the hinge rod 19, so that the rack 15 meshes with the gear 14.

[0044] Next, continue rotating the first screw head 24, causing the rotating plate 8 to move outward along the sliding hole 6. Under the action of the rack 15, the gear 14 rotates, which drives the worm 13 to rotate. The worm 13 drives the worm wheel 10 to rotate, and the worm wheel 10 drives the rotating plate 8 to rotate. The rotating plate 8 rotates outward around the sliding shaft 7, further tightening the cable 25 and further winding it onto the limiting wheel 9. The contact length between the cable 25 and the limiting wheel 9 increases, and the state at this time is as follows: Figure 8 As shown, the cable 25 is in a tightened state. This allows the second slider 5 to be mounted more stably on the tensioning assembly, fixing the cable 25 and preventing the substrate 1 from sliding along the cable 25 when there is strong wind.

[0045] This device is easy to operate. While tensioning the cable 25, it can also fix the cable 25 to the base plate 1, which effectively improves the installation efficiency of the cable 25 and enhances its stability.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
