Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cable tensioning device for coaxial cable processing. Background Technology

[0002] Coaxial cable, also known as radio frequency coaxial cable, is a type of cable with two concentric conductors, widely used in communications, broadcasting, television, radar, medical, and other fields. In home theaters, broadcast television, and data networks, coaxial cable is favored for its superior signal transmission performance, good anti-interference capabilities, and stable signal quality.

[0003] If coaxial cables are too loose during use, it may lead to unstable signal transmission or even interruption. At the same time, although existing tensioning devices require the cable to maintain a certain tension, excessive tension may damage the internal structure of the cable.

[0004] Therefore, there is an urgent need to provide a coaxial cable processing inlet tensioning device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wire tensioning device for coaxial cable processing.

[0006] To solve the above-mentioned technical problems, the present invention provides a technical solution as follows: a coaxial cable processing infeed tensioning device is provided, comprising a base plate, a side plate fixedly mounted on one side of the base plate, and a front-to-back moving mechanism fixedly mounted on the surface of the base plate, and further comprising:

[0007] The side plate is fixedly mounted with a vertical moving mechanism. An adjusting plate is slidably connected inside the vertical moving mechanism. Symmetrical lower tensioning wheels are slidably connected to the surface of the adjusting plate. A positioning mechanism is fixedly mounted inside both the front-to-back moving mechanism and the vertical moving mechanism.

[0008] The present invention is further configured such that: the forward and backward moving mechanism includes a first fixed block, the first fixed block is fixedly installed on the surface of the base plate, a first lead screw is rotatably connected between the first fixed block and the side plate, a moving block is threadedly connected to the surface of the first lead screw, a symmetrical first guide rod is fixedly installed between the first fixed block and the side plate, and the moving block is slidably connected to the surface of the first guide rod.

[0009] With the above technical solution, when the first lead screw rotates, the moving block moves on the surface of the first lead screw, thereby causing the upper tensioning wheel and the lower tensioning wheel to move back and forth until they are on the same vertical plane as the cable, thus facilitating the tensioning of the cable. The setting of the first guide rod makes the moving block more stable when moving.

[0010] The present invention is further configured such that: the up-and-down moving mechanism includes a second fixed block, the second fixed block is fixedly installed on the surface of the side plate, a second lead screw is rotatably connected between the moving block and the second fixed block, and a second guide rod is fixedly installed between the moving block and the second fixed block.

[0011] With the above technical solution, when the second lead screw rotates, the adjusting plate can move up and down, so that the upper tension wheel and the lower tension wheel are in contact with the cable surface. The setting of the second guide rod makes the adjusting plate more stable when moving up and down.

[0012] The present invention is further configured such that: an adjusting plate is threadedly connected to the surface of the second lead screw, the adjusting plate is slidably connected to the surface of the second guide rod, an upper tensioning wheel is rotatably connected to the surface of the adjusting plate, symmetrical sliding grooves are formed on the surface of the adjusting plate, and a plurality of first insertion holes are formed on the surface of the adjusting plate.

[0013] Through the above technical solution, the adjusting plate can move up and down on the surface of the second lead screw and the second guide rod to tension the cable. The setting of the slide groove facilitates the position adjustment of the lower tensioning wheel, thereby adjusting the tension according to the cable requirements.

[0014] The present invention is further configured such that: cable grooves are provided on the surfaces of the upper tensioning wheel and the lower tensioning wheel; a sliding rod is slidably connected inside the groove; the lower tensioning wheel is rotatably connected to the surface of the sliding rod; a second insertion hole is provided on the surface of the sliding rod; and a pin is movably inserted into both the first insertion hole and the second insertion hole.

[0015] Through the above technical solution, the cable groove facilitates the placement of cables and limits their movement. The slide bar moves inside the groove, thereby allowing the positions of the two lower tensioning rollers to be adjusted. Through the cooperation of the pin with the first and second insertion holes, the lower tensioning rollers can be fixed again after their positions are adjusted.

[0016] The present invention is further configured such that: the positioning mechanism includes a turntable, one end of the first lead screw and the second lead screw are fixedly mounted on the turntable, a positioning rod is slidably connected inside the turntable, and multiple positioning holes are opened on the surfaces of the first fixed block and the second fixed block, and the positioning rod is movably inserted into the positioning hole.

[0017] With the above technical solution, when the turntable rotates, it drives the first lead screw and the second lead screw to rotate, thereby moving the moving block and the adjusting plate, realizing the position adjustment of the upper tensioning wheel and the lower tensioning wheel. Through the cooperation of the positioning rod and the positioning hole, the upper tensioning wheel and the lower tensioning wheel can be fixed after the position is adjusted, so as to avoid the position movement during the tensioning process from affecting the tensioning effect.

[0018] The present invention is further configured such that: a positioning groove is formed on the surface of the turntable, a positioning ring is fixedly installed on the surface of the positioning rod, the positioning rod and the positioning ring are slidably connected inside the positioning groove, a spring is fixedly installed on the surface of the positioning ring, and the other end of the spring is fixedly connected to the inner wall of the positioning groove.

[0019] With the above technical solution, when the positioning rod is pulled out, the turntable can rotate. When the moving block and the adjusting plate rotate to the appropriate position, the positioning rod is released. Under the action of the spring and the positioning ring, the positioning rod can be inserted into the corresponding positioning hole, thereby fixing the moving block and the adjusting plate and preventing rotation from affecting the tensioning effect.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model is equipped with a front-to-back moving mechanism and a vertical moving mechanism. By rotating the turntable, the upper and lower tensioning wheels can be brought into contact with the cable to perform tensioning work, ensuring that the cable maintains appropriate tension during transmission and extending the cable's service life. A limit mechanism is provided, which, through the cooperation of positioning holes and positioning rods, can fix the position of the moving block and the adjusting plate, preventing the moving block and the adjusting plate from moving due to the reaction force of the cable during the tensioning process, thus affecting the tensioning effect.

[0028] Please see Figures 1-4 This application provides a coaxial cable processing inlet tensioning device, including a base plate 1, a side plate 2 fixedly installed on one side of the base plate 1, and a front-back moving mechanism 3 fixedly installed on the surface of the base plate 1.

[0029] like Figure 2 As shown, the forward and backward moving mechanism 3 includes a first fixed block 31, which is fixedly installed on the surface of the base plate 1. A first lead screw 32 is rotatably connected between the first fixed block 31 and the side plate 2. A moving block 33 is threadedly connected to the surface of the first lead screw 32. A symmetrical first guide rod 34 is fixedly installed between the first fixed block 31 and the side plate 2. The moving block 33 is slidably connected to the surface of the first guide rod 34.

[0030] In this embodiment: when the first lead screw 32 rotates, the moving block 33 moves on the surface of the first lead screw 32, thereby causing the upper tensioning wheel 51 and the lower tensioning wheel 6 to move back and forth until they are on the same vertical plane as the cable, so as to facilitate the tensioning of the cable. The first guide rod 34 makes the moving block 33 more stable when it moves.

[0031] A vertical moving mechanism 4 is fixedly installed on the surface of the side plate 2. An adjusting plate 5 is slidably connected inside the vertical moving mechanism 4. Symmetrical lower tensioning wheels 6 are slidably connected on the surface of the adjusting plate 5. A positioning mechanism 7 is fixedly installed inside both the front-to-back moving mechanism 3 and the vertical moving mechanism 4.

[0032] like Figure 2 As shown, the up-down moving mechanism 4 includes a second fixed block 41, which is fixedly installed on the surface of the side plate 2. A second lead screw 42 is rotatably connected between the moving block 33 and the second fixed block 41, and a second guide rod 43 is fixedly installed between the moving block 33 and the second fixed block 41.

[0033] In this embodiment: when the second lead screw 42 rotates, the adjusting plate 5 can move up and down, so that the upper tensioning wheel 51 and the lower tensioning wheel 6 are in contact with the cable surface. The setting of the second guide rod 43 makes the adjusting plate 5 more stable when moving up and down.

[0034] like Figure 2 As shown, the second lead screw 42 is threadedly connected to an adjusting plate 5, which is slidably connected to the surface of the second guide rod 43. The adjusting plate 5 is rotatably connected to an upper tensioning wheel 51, and the adjusting plate 5 has symmetrical sliding grooves 52 and multiple first insertion holes 53.

[0035] In this embodiment, the adjusting plate 5 can move up and down on the surfaces of the second lead screw 42 and the second guide rod 43 to tension the cable. The groove 52 facilitates the adjustment of the position of the lower tensioning wheel 6, thereby adjusting the tension according to the cable's requirements.

[0036] like Figure 3 As shown, cable grooves 61 are provided on the surfaces of the upper tensioning wheel 51 and the lower tensioning wheel 6. A sliding rod 62 is slidably connected inside the sliding groove 52. The lower tensioning wheel 6 is rotatably connected to the surface of the sliding rod 62. A second insertion hole 63 is provided on the surface of the sliding rod 62. A pin 64 is movably inserted into both the first insertion hole 53 and the second insertion hole 63.

[0037] In this embodiment: the cable groove 61 facilitates the placement of the cable and limits its position. The slide bar 62 moves inside the slide groove 52, thereby allowing the positions of the two lower tensioning rollers 6 to be adjusted. Through the cooperation of the pin 64 with the first insertion hole 53 and the second insertion hole 63, the lower tensioning rollers 6 can be fixed again after their positions are adjusted.

[0038] like Figure 4 As shown, the positioning mechanism 7 includes a turntable 71. One end of the first lead screw 32 and the second lead screw 42 are fixedly installed with the turntable 71. A positioning rod 72 is slidably connected inside the turntable 71. Multiple positioning holes 73 are opened on the surface of the first fixing block 31 and the second fixing block 41. The positioning rod 72 is movably inserted into the positioning hole 73.

[0039] In this embodiment: when the turntable 71 rotates, it drives the first lead screw 32 and the second lead screw 42 to rotate, thereby moving the moving block 33 and the adjusting plate 5, realizing the position adjustment of the upper tensioning wheel 51 and the lower tensioning wheel 6. Through the cooperation of the positioning rod 72 and the positioning hole 73, the upper tensioning wheel 51 and the lower tensioning wheel 6 can be fixed after the position is adjusted, so as to avoid the position movement during the tensioning process from affecting the tensioning effect.

[0040] like Figure 4 As shown, a positioning groove 75 is provided on the surface of the turntable 71, and a positioning ring 74 is fixedly installed on the surface of the positioning rod 72. The positioning rod 72 and the positioning ring 74 are slidably connected inside the positioning groove 75. A spring 76 is fixedly installed on the surface of the positioning ring 74, and the other end of the spring 76 is fixedly connected to the inner wall of the positioning groove 75.

[0041] In this embodiment: when the positioning rod 72 is pulled out, the turntable 71 can rotate. When the moving block 33 and the adjusting plate 5 rotate to the appropriate position, the positioning rod 72 is released. Under the action of the spring 76 and the positioning ring 74, the positioning rod 72 can be inserted into the corresponding positioning hole 73, thereby fixing the moving block 33 and the adjusting plate 5 and preventing rotation from affecting the tensioning effect.

[0042] In use, the positioning rod 72 inside the turntable 71 is pulled out, and the positioning rod 72 moves out from the positioning hole 73 on the surface of the first fixed block 31. The turntable 71 is rotated, and the first lead screw 32 rotates, thereby moving the moving block 33 on the surface of the first lead screw 32. After moving to the appropriate position, the positioning rod 72 is released, and the positioning rod 72 is inserted into the corresponding positioning hole 73 to fix the position of the moving block 33. Similarly, the position of the adjusting plate 5 can be fixed. The upper tensioning wheel 51 and the lower tensioning wheel 6 are respectively attached to the cable to perform tensioning work.
