[0001] The present invention relates to the technical field of cable harnesses, and more particularly to a double-row cable harness tightening device. Background Art

[0002] Double-row cable refers to a cable that contains two cable lines at the same time. This type of cable is usually used to transmit bidirectional data or signals, such as network communication, audio transmission, etc. The double-row cable design can reduce the number of cables and occupied space, and can simplify the wiring and installation process.

[0003] In the process of using cables, due to the large number of connected devices, multiple double-row cables are usually required to be used together. Therefore, the double-row cables installed side by side are relatively messy, which is not only unsightly, but also inconvenient for later maintenance. The existing method is often to bundle them together by cable ties or steel wires, but this tightening method is more suitable for single cables. When tightening the double-row cables, they cannot be combined at will because they are not cylindrical like single cables. The cables need to be sorted, otherwise the tightening effect is not ideal, and when the two cables of the double-row cable need to be connected to different positions, it is not convenient to identify the single double-row cable.

[0032] Second embodiment

[0033] As attached Figure 1-6In one embodiment of the present invention, when the clamping joints 27 on both sides of an adjustment component 1 are squeezed to the bottom of the sleeve frame 22 on both sides of another adjustment component 1, the clamping joints 27 are squeezed, so that the extrusion groove 25 is compressed, and the pressing block 26 and the limit block 28 are respectively moved into the movable groove 24 and the extrusion groove 25. The clamping joint 27 moves to the side, and under the reset action of the reset spring 29, the clamping joint 27 is clamped in the clamping groove 23.

Under the action of the pressing block 26, the clamping joint 27 moves to the side, so that the clamping joint 27 is disengaged from the inside of the clamping groove 23, thereby separating the multiple clamping frames 21 from each other and disassembling the multiple clamping components 2.

[0037] The two sides of the clamping joint 27 are provided with inclined surfaces, and the clamping joints 27 at two ends of one adjusting component 1 are clamped and installed in the clamping grooves 23 at the bottom of the clamping frame 21 at two ends of the other adjusting component 1.

[0038] Third embodiment

[0039] like Figure 1-4 ,7 is an embodiment of the present invention, by rotating the fastening bolt 35, the extrusion plate 36 is moved closer to the positioning block 32, and when the double-row cable 4 is placed between the positioning block 32 and the extrusion plate 36, when the sleeve 39 is sleeved on the outer surface of the double-row cable 4, the sleeve 39 will be deformed and wrapped around the outer surface of the double-row cable 4, which can not only fix the double-row cables 4 of different diameters, but also because the material of the sleeve 39 is elastic material, it can prevent the double-row cable 4 from being squeezed and deformed, or the surface from being worn, thereby avoiding reducing the service life of the double-row cable 4.

[0040] The third embodiment is further optimized relative to the second embodiment in that the fastening assembly 3 includes a support plate 31, the support plate 31 is L-shaped, one end of the top of the support plate 31 is fixedly connected to a positioning block 32, and both ends of the top of the support plate 31 away from the positioning block 32 are provided with movable grooves 33, a bottom block 311 is slidably installed inside the movable groove 33, and the top of the bottom block 311 is fixedly connected to an extrusion plate 36.

[0041] Among them, a positioning plate 34 is fixedly connected to one side of the top of the support plate 31, and a fastening bolt 35 is connected to the internal thread of the positioning plate 34. The fastening bolt 35 is rotatably installed on one side of the extrusion plate 36. One side of the support plate 31 is fixedly connected to the connecting rod 110 by bolts. The support plate 31 is movably sleeved on the outer surface of one side of the fixed plate 11, and one side of the rotating rod 15 is rotatably installed with one side of the support plate 31.

[0042] Among them, a groove 37 is provided on the side facing the positioning block 32 and the extrusion plate 36, and a positioning groove 38 is provided at the lower end of the positioning block 32 and the extrusion plate 36. A belt 39 is movably sleeved on the side facing the positioning block 32 and the extrusion plate 36, and both ends of the belt 39 are fixedly connected with a positioning clip 310. The positioning clip 310 is respectively clamped and installed on the top of the positioning block 32 and the extrusion plate 36 and inside the positioning groove 38 at the lower end of the positioning block 32 and the extrusion plate 36.

[0043] Among them, the shape of the groove 37 is trapezoidal, the material of the sleeve 39 is elastic material, and the sleeve 39 is snap-fitted and installed on the outer surface of the double-row cable 4. Since the shape of the groove 37 is trapezoidal, the four sides of the double-row cable 4 can be fixed through the inclined surfaces on both sides of the groove 37, and thus the double-row cables 4 of different diameters can be fixed.

[0044] Working principle of the present invention: When in use, the single cables on both sides of the double-row cable 4 are placed between the positioning blocks 32 and the extrusion plates 36 on both sides of the adjustment assembly 1 respectively, and the extrusion plates 36 are moved closer to the positioning blocks 32 by rotating the fastening bolts 35. When the sleeve 39 is sleeved on the outer surface of the double-row cable 4, the sleeve 39 will be deformed and wrapped around the outer surface of the double-row cable 4 to fix the double-row cables 4 of different diameters.

[0045] Subsequently, according to the connection position of the double-row cables 4, the adjusting knob 13 is turned to rotate the rotating screw 12, the sliding block 14 slides on the top of the fixed plate 11, and pushes the rotating rod 15 to rotate, pushing the fastening components 3 on both sides of the adjusting component 1 to move toward or in the opposite direction, thereby adjusting the position and distance of the single cables on both sides of the double-row cables 4. At this time, the fastening component 3 pulls the connecting rod 110 outward to both sides, the sliding sleeve 17 moves on the outer surface of the fixed rail 16, and the connecting sleeve 19 moves on the outer surface of the movable rail 18, so that the fixed rail 16 and the connecting rod 110 are unfolded to support the fastening component 3.

[0046] When the clamping joints 27 on both sides of one adjusting component 1 are squeezed to the bottom of the sleeve frame 22 on both sides of another adjusting component 1, the clamping joints 27 are squeezed, so that the extrusion groove 25 is compressed, and the pressing block 26 and the limiting block 28 are respectively moved into the inside of the movable groove 24 and the extrusion groove 25, and the clamping joints 27 move sideways, and under the resetting action of the reset spring 29, the clamping joints 27 are clamped in the inside of the clamping groove 23, and multiple tightening devices can be clamped with each other to complete the fixation. When any double-row cable 4 is to be split, when one side of the pressing block 26 is pressed, the limiting block 28 is moved to the inside of the extrusion groove 25, and the reset spring 29 is squeezed. Under the action of the pressing block 26, the clamping joint 27 moves sideways, so that the clamping joint 27 is separated from the inside of the clamping groove 23, thereby separating the multiple clamping frames 21 from each other, and decomposing the multiple clamping components 2.

[0047] Finally, a few points should be explained: the drawings of the embodiments disclosed in the present invention only involve structures related to the embodiments disclosed in the present invention, and other structures can refer to the usual design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
