Description

Technical Field

[0001] The invention relates to the technical field of cable laying and installation brackets, in particular to an adjustable support and hanger bracket used for cable laying and installation. Background Art

[0002] Cable is a type of transmission device for electric energy or signals, usually composed of several or several groups of wires. Cables need to be arranged vertically using cable hangers in factories or special scenarios to facilitate neatly arranging and fixing cables for use and avoid cluttered lines.

[0003] However, in the prior art, in order to ensure the safety, stability and effective operation of the cable, the tightness of the cable needs to be constantly adjusted during the laying and installation process. However, during the process of adjusting the tightness, the cable is prone to twisting or falling from the support bracket, resulting in damage to the cable. It is difficult to limit the cable in multiple directions during the process of adjusting the tightness of the cable to prevent damage to the cable.

[0004] At present, in order to improve the stability of cables on supports and hangers, cables are often simply fixed on supports and hangers. However, when encountering stormy weather, insufficient fixing force may easily lead to damage to the cables themselves or affect the stable operation of the entire electrical system. It is difficult to perform multiple synchronous fixations on the cables through supports and hangers to enhance the stability of the cables on supports and hangers.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The object of the present invention is to provide an adjustable support and hanger for cable laying and installation, so as to solve the technical defects proposed by the background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable support and hanger for cable laying and installation, comprising a mounting frame, a cavity is provided inside the mounting frame, a slideway is provided on the side wall of the mounting frame, a threaded rod is rotatably provided in the cavity, a plurality of slides are threadedly connected on the outer wall of the threaded rod, one end of the slide is fixedly connected to an upper limit plate through the slideway, an upper limit piece is provided in the middle of the upper limit piece, a lower pressing roller is provided below the upper limit piece, and an adjustment and fixing component is provided on the side of the upper limit plate;

[0008] The adjusting and fixing assembly includes two notches on both sides of the top of the upper limit plate, and two lower slide grooves are provided at the bottom of the upper limit plate, and the lower slide grooves are connected to the corresponding notches, and a bidirectional threaded screw is rotatably arranged in the lower slide groove, and one end of the bidirectional threaded screw is rotatably connected to the inner wall of the notch through a connecting shaft, and side pressing rollers are connected to the outer walls of both sides of the bidirectional threaded screw through side U-shaped plates, and a gear is fixedly arranged on the outer wall of the connecting shaft, and the gear is meshed with a tooth plate, and the tops of the two tooth plates extend to above the upper limit plate and a connecting plate is fixedly arranged.

[0009] Furthermore, the two notches are symmetrically arranged relative to the center line of the threaded rod, and the two side U-shaped plates located on the same bidirectional threaded screw rod are arranged corresponding to each other.

[0010] Furthermore, the side wall of the connecting plate is fixedly connected to the mounting frame via a fixing plate.

[0011] Furthermore, a lower limit plate is fixedly provided at the bottom end of the lower pressing roller, and a side wall of the lower limit plate is fixedly connected to the mounting frame.

[0012] Furthermore, the upper limit positioning member includes an upper U-shaped plate slidably connected to the upper limit positioning plate, the top of the upper limit positioning plate is fixedly connected to a limiting rod, the limiting rod is slidingly matched with the middle part of the upper U-shaped plate, the limiting rod is located on the outer wall above the upper U-shaped plate and a thrust spring is sleeved on the upper U-shaped plate, and an upper pressing roller is rotatably provided at the bottom of the upper U-shaped plate.

[0013] Furthermore, the bottom end of the threaded rod extends outside the mounting frame and is fixedly provided with a handle, and a plurality of mounting plates are fixedly connected to the side wall of the mounting frame away from the slideway.

[0014] The method of using the adjustable support hanger for cable laying and installation is as follows:

[0015] Step 1: Fix the mounting frame on the wall through multiple mounting plates. Then, install multiple cables on the lower pressing roller. Turn the handle to control the rotation of the threaded rod, so that the multiple slides drive the upper limit plate to move downward, so that the upper pressing roller contacts the top of the cable, and the lower part of the side pressing roller is located on both sides of the cable. At this time, the teeth on the tooth plate do not contact the gear.

[0016] Step 2: Then, the tightness of the cable is adjusted by pulling the cable. During this process, the upper pressing roller, the lower pressing roller and the side pressing roller all limit the pulling adjustment of the cable in multiple directions to prevent the cable from bending, twisting or falling during the pulling process;

[0017] Step 3: After the cable tightness is adjusted, turn the handle again to adjust the position of the slide plate so that the upper limit plate drives the upper pressing roller to press and fix the cable. During this process, the gear is meshed with the bottom of the toothed plate, so that the gear drives the bidirectional threaded screw to rotate through the connecting shaft, and the two side pressing rollers move closer to each other to synchronously fix both sides of the cable; finally, stop turning the handle to complete the laying and installation of the cable.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, the tightness of the cable is adjusted by pulling the cable, and the upper pressing roller, the lower pressing roller and the side pressing roller all limit the pulling adjustment of the cable in multiple directions, thereby preventing the cable from bending, twisting or falling during the pulling process, reducing the mechanical stress on the cable, and preventing the cable from being damaged;

[0020] In the present invention, after the cable tension is adjusted, the handle is turned again to adjust the position of the slide plate again, so that the upper limit plate drives the upper pressing roller to press and fix the cable. At the same time, the gear is meshed and connected with the bottom of the toothed plate, so that the gear drives the bidirectional threaded screw to rotate through the connecting shaft, and the two side pressing rollers move closer to each other to synchronously fix the two sides of the cable. By performing multiple synchronous fixations on the cable, the stability of the cable on the support bracket is enhanced.

[0021] In the present invention, the cable is limited in multiple directions when it is laid to ensure the stability of the cable when adjusting the tension and avoid damage to the cable. After the cable adjustment is completed, the middle and both sides of the cable are synchronously limited and fixed to ensure the stability of the cable on the support bracket, thereby jointly improving the reliability and safety of the cable when it is laid.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: Figure 1-7 As shown, an adjustable support and hanger for cable laying and installation proposed in this embodiment includes a mounting frame 1, a cavity is opened inside the mounting frame 1, a slideway 4 is opened on the side wall of the mounting frame 1, a threaded rod 7 is rotatably arranged in the cavity, a plurality of slide plates 5 are threadedly connected on the outer wall of the threaded rod 7, one end of the slide plate 5 passes through the slideway 4 and is fixedly connected to an upper limit plate 6, an upper limit piece is arranged in the middle of the upper limit plate 6, a lower pressing roller 11 is arranged below the upper limit piece, and an adjustment fixing component is arranged on the side of the upper limit plate 6;

[0033] It should be noted here that the cavity and the slideway 4 are interconnected;

[0034] The adjusting and fixing assembly includes two notches 86 provided on both sides of the top of the upper limit plate 6, and two lower slide grooves 810 are provided on the bottom of the upper limit plate 6, and the lower slide groove 810 is connected with the corresponding notch 86, and a bidirectional threaded screw 83 is rotatably arranged in the lower slide groove 810, and one end of the bidirectional threaded screw 83 is rotatably connected to the inner wall of the notch 86 through a connecting shaft 87, and side pressing rollers 82 are connected to the outer walls of both sides of the bidirectional threaded screw 83 through side U-shaped plates 81, and a gear 84 is fixedly provided on the outer wall of the connecting shaft 87, and the gear 84 is meshedly connected with a tooth plate 85, and the tops of the two tooth plates 85 extend to the upper part of the upper limit plate 6 and are fixedly provided with a connecting plate 89, and the side wall of the connecting plate 89 is fixedly connected to the mounting frame 1 through a fixing plate 88;

[0035] Turn the handle 3 to control the threaded rod 7 to rotate, so that the multiple slide plates 5 drive the upper limit plate 6 to move downward, so that the upper pressing roller 92 contacts the top of the cable, and the lower part of the side pressing roller 82 is located on both sides of the cable. The upper pressing roller 92, the lower pressing roller 11 and the side pressing roller 82 are used to limit the pulling adjustment of the cable to avoid bending, twisting or falling of the cable during the pulling process, reduce the mechanical stress on the cable, and prevent the cable from being damaged;

[0036] After the cable tightness is adjusted, turn the handle 3 again so that the upper limit plate 6 drives the upper pressing roller 92 to press and fix the cable. At the same time, the two side pressing rollers 82 move closer to each other to synchronously fix the two sides of the cable. By multiple fixations of the cable, the stability of the cable on the support bracket is enhanced, and the reliability and safety of the cable during laying are improved.

[0037] like Figure 1-3 , 5-7, the two notches 86 are symmetrically arranged relative to the midline of the threaded rod 7, and the two side U-shaped plates 81 located on the same bidirectional threaded screw 83 are arranged corresponding to each other;

[0038] When the two side U-shaped plates 81 are brought closer to each other, the two side pressing rollers 82 are driven to move closer to each other, thereby completing the fixed position limitation of the cable.

[0039] like Figure 1-3 As shown in 6-7, a lower limit plate 10 is fixedly provided at the bottom end of the lower pressing roller 11, and the side wall of the lower limit plate 10 is fixedly connected to the mounting frame 1; wherein, the lower limit plate 10 serves the purpose of limiting the lower pressing roller 11.

[0040] like Figure 1-7 As shown, the upper limit member includes an upper U-shaped plate 91 slidably connected to the upper limit plate 6, a limit rod 93 is fixedly connected to the top of the upper limit plate 6, the limit rod 93 is slidably matched with the middle part of the upper U-shaped plate 91, a thrust spring 94 is sleeved on the outer wall of the limit rod 93 located above the upper U-shaped plate 91, and an upper pressing roller 92 is rotatably provided at the bottom of the upper U-shaped plate 91;

[0041] It should be noted that friction bumps are provided on the outer walls of the upper pressing roller 92 , the lower pressing roller 11 and the side pressing roller 82 to improve the firmness of the upper pressing roller 92 , the lower pressing roller 11 and the side pressing roller 82 in fixing the cable.

[0042] Before adjusting the cable tension: the slide plate 5 drives the upper limit plate 6 to move downward, so that the upper pressing roller 92 contacts the top of the cable; after adjusting the cable tension: turn the handle 3 again, so that the upper limit plate 6 drives the upper pressing roller 92 to press and fix the cable, so that the upper U-shaped plate 91 squeezes the thrust spring 94 upward.

[0045] The threaded rod 7 can be driven to rotate by rotating the handle 3. Since the slide plate 5 is limited by the slideway 4, the slide plate 5 drives the upper limit plate 6 to move downward in the slideway 4, thereby adjusting the position of the slide plate 5.

[0046] The handle 3 is provided with friction patterns to increase the friction force on its surface.

[0047] In this embodiment: when laying the cable, the cable is limited in multiple directions to ensure the stability of the cable when adjusting the tension, thereby avoiding damage to the cable.

[0048] The method of using the adjustable support hanger for cable laying and installation is as follows:

[0049] Step 1: Fix the mounting frame 1 on the wall through multiple mounting plates 2, then install multiple cables on the lower pressing roller 11, turn the handle 3, control the threaded rod 7 to rotate, and let the multiple slide plates 5 drive the upper limit plate 6 to move downward, so that the upper pressing roller 92 contacts the top of the cable, and the lower part of the side pressing roller 82 is located on both sides of the cable, and the teeth on the tooth plate 85 do not contact the gear 84;

[0050] Step 2: Then, the tightness of the cable is adjusted by pulling the cable. During this process, the upper pressing roller 92, the lower pressing roller 11 and the side pressing roller 82 all limit the pulling adjustment of the cable in multiple directions to prevent the cable from bending, twisting or falling during the pulling process, reduce the mechanical stress on the cable, and prevent the cable from being damaged;

[0051] Step 3: After the cable tightness is adjusted, turn the handle 3 again to adjust the position of the slide plate 5 so that the upper limit plate 6 drives the upper pressing roller 92 to press and fix the cable.
