Description

Technical Field

[0001] The utility model belongs to the technical field of suspension fittings, and more particularly, to a suspension fitting for a straight-line pole tower that is easy to adjust. Background Art

[0002] A straight-line pole tower refers to a pole tower used for the straight section of an overhead line, and its conductors are suspended by suspension clamps (also known as suspension fittings and support fittings). The conductors are suspended by pin-type or post-type insulators. The design form of the straight-line pole tower for AC UHV transmission lines mainly adopts the cat-head type tower, with the conductors arranged in a "V" string in the middle phase and an "I" string on the side phases. The minimum vertical distance between the middle-phase conductor and the lower-phase conductor is about 16 m, and the minimum horizontal distance between the two side-phase conductors is about 30 m. Therefore, the line corridor can be reduced to the narrowest. To save the line corridor and reduce the demolition cost, this type of cat-head type series straight-line tower is generally adopted.

[0003] Among them, Chinese Patent CN202223368325.4 discloses a suspension fitting, which includes a mounting plate and an anti-sway mechanism; an anti-sway mechanism is connected to the lower side of the mounting plate. The anti-sway mechanism includes a mounting cavity, an anti-sway member is arranged in the mounting cavity, several support balls are arranged on the lower side of the anti-sway member, a wire harness clamp is arranged on the lower side of the mounting cavity, a positioning ring is connected between the mounting cavity and the anti-sway member, a positioning groove matching the positioning ring is drilled on the anti-sway member, an extrusion groove matching the mounting cavity is drilled on the anti-sway member, a placement groove matching the support ball is drilled on the mounting cavity, a placement bearing is connected between the support ball and the mounting cavity, and the anti-sway member penetrates through the mounting cavity.

[0004] When the existing suspension fitting for a straight-line pole tower fixes the wire harness through the wire harness clamp, although the wire harness clamp is hinged through a hinge structure, since the wire harness is not only a single bundle, the wire harness clamp in a single direction can only be used for installing and using the wire harness in a single direction, and cannot install and connect multiple wire harnesses, which is relatively single, thus reducing the applicability of the wire harness clamp.

[0005] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] Regarding the problems in the related art, the present utility model proposes a suspension fitting for a straight-line pole tower that is easy to adjust to overcome the above-mentioned technical problems existing in the prior related art.

[0007] To solve the above technical problems, the present utility model is achieved through the following technical solutions:

[0008] The utility model relates to a suspension fitting for a straight-line pole tower which is convenient to adjust, comprising a mounting plate and two wire harness clips. An adjusting assembly and a fixing assembly are respectively arranged below the mounting plate. The adjusting assembly is used to rotate and adjust the using direction of the wire harness clips so as to clamp and limit wire harnesses in different directions. The fixing assembly is used to fix the using position of the adjusting assembly to prevent the adjusted wire harness clips and the adjusting assembly from shaking. Four mounting rods are connected to the bottom end of the mounting plate, and both of the two wire harness clips are arranged below the mounting plate.

[0009] Furthermore, the adjusting assembly comprises two mounting frames, two limiting sliding rings and a connecting seat.

[0010] Furthermore, the inner sides of the two connecting seats are respectively rotatably connected to the surfaces of the two adjusting cylinders. The bottom ends of the two adjusting cylinders are respectively connected to the top ends of the two wire harness clips.

[0011] Furthermore, the fixing assembly comprises two fixing cylinders, two rotating blocks and two rubber pads. Threaded blocks are connected to the surfaces of the two fixing cylinders. The two threaded blocks are respectively in threaded connection with the inner sides of the top ends of the two mounting frames. Mounting bolts are connected to the inner sides of the two fixing cylinders. Rotating blocks are connected to the bottom ends of the two mounting bolts. Limiting blocks are connected to the bottom ends of the two rotating blocks. Silicone pads are connected to the surfaces of the two limiting blocks.

[0014] The utility model has the following beneficial effects:

[0015] 1. First, the mounting plate and the wire harness clip of the present utility model are installed through a hinged structure to form a suspension fitting. Here, only the mounting plate and the wire harness clip are highlighted, but the mounting plate and the wire harness clip as a whole are the suspension fitting, and other components are not shown. When it is necessary to adjust the use orientation of the two wire harness clips, first turn the fixing component to disengage the fixing component from the adjusting component, rotate the adjusting component to drive the wire harness clip to the corresponding angle, and then thread-fix the fixing component to the adjusting component again. Then, the fixing component can be snapped into the interior of the adjusting component to prevent the adjusting component from shifting after adjustment. One wire harness can be clamped in parallel by the two wire harness clips, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips, improving the flexibility of use;

[0016] 2. The present utility model prevents the adjusting cylinder from disengaging from the fixing ring through the rotational limiting effect of the limiting slip ring, and the adjusting cylinder that can be rotated and adjusted conveniently drives the corresponding wire harness clip to adjust the use orientation. One wire harness can be clamped in parallel by the two wire harness clips, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips;

The present utility model facilitates controlling the up-and-down movement of the limiting block through the fixing cylinder and the mounting bolt both threadedly connected to the mounting frame. By controlling the upward movement of the limiting block, it can be separated from the inner wall of the adjusting cylinder, and thus the use orientation of the wire harness clip can be adjusted. By controlling the downward movement of the limiting block and the silicone pad to closely adhere to the inner wall of the adjusting cylinder, the rotation of the adjusting cylinder can be restricted, thereby preventing the wire harness clip with the adjusted use orientation from shifting and preventing instability after the wire harness is installed. While improving the overall flexibility of the wire harness clip, it also facilitates fixing the position of the wire harness clip.

[0029] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the utility model.

[0030] Please refer to Figures 1 - 6 As shown in the figure, the present utility model is a suspension fitting for a straight-line pole tower that is easy to adjust, including a mounting plate 1 and two wire harness clips 5. Below the mounting plate 1, an adjusting assembly 2 and a fixing assembly 3 are respectively provided. The adjusting assembly 2 is used to rotate and adjust the use orientation of the wire harness clip 5 to clamp and limit wire harnesses in different directions. The fixing assembly 3 is used to fix the use position of the adjusting assembly 2 to prevent the adjusted wire harness clip 5 and adjusting assembly 2 from shaking. Four mounting rods 4 are connected to the bottom end of the mounting plate 1, and both of the two wire harness clips 5 are arranged below the mounting plate 1.

[0031] First, the mounting plate 1 and the wire harness clip 5 are installed through a hinged structure to form a suspension fitting. Here, only the mounting plate 1 and the wire harness clip 5 are highlighted, but the mounting plate 1 and the wire harness clip 5 as a whole are the suspension fitting, and other components are not shown. When it is necessary to adjust the use orientation of the two wire harness clips 5, first turn the fixing component 3 to disengage the fixing component 3 from the adjusting component 2, rotate the adjusting component 2 to drive the wire harness clip 5 to a corresponding angle, and then thread-fix the fixing component 3 to the adjusting component 2 again. Then, the fixing component 3 can be snapped into the interior of the adjusting component 2 to prevent the adjusting component 2 from shifting after adjustment. One wire harness can be clamped in parallel by the two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips 5, improving the flexibility of use.

[0032] The adjusting component 2 facilitates the adjustment of the use orientation of the wire harness clip 5. One wire harness can be clamped in parallel by the two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips 5, improving the flexibility of use. The fixing component 3 facilitates clamping and limiting the adjusting component 2 after adjustment to prevent the wire harness clip 5 from shifting after adjustment.

[0033] In one embodiment, for the above-mentioned adjusting component 2, the adjusting component 2 includes two mounting frames 21, two limiting slip rings 23, and a connecting seat 25. Each mounting frame 21 is respectively arranged between every two mounting rods 4. The bottom ends of the two mounting frames 21 are both connected with fixing rings 22. The two limiting slip rings 23 are respectively rotatably arranged inside the two fixing rings 22. The bottom ends of the two limiting slip rings 23 are both connected with adjusting cylinders 24. The two connecting seats 25 are respectively arranged inside the two mounting frames 21.

[0034] First, the mounting plate 1 and the wire harness clip 5 are installed through a hinged structure to form a suspension fitting. Here, only the mounting plate 1 and the wire harness clip 5 are highlighted, but the mounting plate 1 and the wire harness clip 5 as a whole are the suspension fitting, and other components are not shown. When it is necessary to adjust the usage orientation of the two wire harness clips 5 to install wire harnesses in different directions, first turn the fixing component 3, and then move the fixing component 3 upward so that the fixing component 3 is disengaged from the inner top of the mounting frame 21 and the inner part of the adjusting cylinder 24. Rotating the adjusting cylinder 24 can drive the wire harness clip 5 to rotate by a corresponding angle. One wire harness can be clamped in parallel by the two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the usage orientation of the two wire harness clips 5. After adjusting the usage position of the wire harness clip 5, screw the fixing component 3 back into the inner part of the mounting frame 21, and limit the adjusting cylinder 24 by clamping the inner part of the fixing component 3 and the adjusting cylinder 24. Since the fixing component 3 and the mounting frame 21 are threadedly connected, it is advisable to screw the fixing component 3 and the mounting frame 21 as tightly as possible, so that the fixing component 3 can penetrate into the adjusting cylinder 24 as much as possible, thereby improving the clamping and fixing effect and preventing the wire harness clip 5 from shifting after the adjustment component 2 is completed.

[0035] By rotating the limiting sliding ring 23 inside the fixing ring 22, it is convenient to drive the adjusting cylinder 24 and the wire harness clip 5 to rotate, which is convenient for adjusting the usage orientation of the wire harness clip 5 accordingly, and improves the overall usage inclusiveness of the wire harness clip 5. One wire harness can be clamped in parallel by the two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the usage orientation of the two wire harness clips 5. The fixing component 3 is convenient for clamping and limiting the adjusting cylinder 24 after the adjustment is completed, preventing the wire harness clip 5 from shifting after the adjustment is completed, and further preventing instability after the wire harness installation is completed.

[0036] In one embodiment, for the above-mentioned connecting seat 25, the inner sides of the two connecting seats 25 are respectively rotatably connected to the surfaces of the two adjusting cylinders 24, and the bottoms of the two adjusting cylinders 24 are respectively connected to the tops of the two wire harness clips 5, so as to drive the wire harness clip 5 to rotate through the adjusting cylinder 24.

[0037] In one embodiment, for the above-mentioned fixing component 3, the fixing component 3 includes two fixing cylinders 31, two rotating blocks 33 and two rubber pads 35. Threaded blocks 36 are connected to the surfaces of the two fixing cylinders 31, and the two threaded blocks 36 are respectively threadedly connected to the inner sides of the tops of the two mounting frames 21. Mounting bolts 32 are connected to the inner sides of the two fixing cylinders 31. The bottoms of the two mounting bolts 32 are both connected with rotating blocks 33, the bottoms of the two rotating blocks 33 are both connected with limit clamping blocks 34, and silicone pads 37 are connected to the surfaces of the two limit clamping blocks 34. The two rubber pads 35 are respectively arranged at the tops of the two fixing cylinders 31, so as to increase the friction force when the operator holds it, making it more stable to hold, and the friction force between the limit clamping block 34 and the inside of the adjusting cylinder 24 is increased through the silicone pad 37, further improving the stability of the adjusting cylinder 24 when being limited.

[0038] In one embodiment, for the above-mentioned mounting bolts 32, the surfaces of the two mounting bolts 32 are respectively threadedly connected to the inner sides of the tops of the two mounting frames 21, so as to facilitate the rotation and movement in cooperation with the fixing cylinder 31.

[0039] In one embodiment, for the above-mentioned silicone pads 37, the surfaces of the two silicone pads 37 are respectively attached to the inner walls of the two adjusting cylinders 24, so as to increase the friction force and stability of the adjusting cylinder 24 when being limited.

[0040] In summary, by means of the above technical solution of the present utility model, first, the mounting plate 1 and the wire harness clip 5 are installed through a hinged structure to form a suspension fitting. Here, only the mounting plate 1 and the wire harness clip 5 are highlighted, but the mounting plate 1 and the wire harness clip 5 as a whole are the suspension fitting, and other components are not shown. When it is necessary to adjust the use orientation of the two wire harness clips 5 to install wire harnesses in different orientations, hold the rubber pad 35 used to increase the friction and twist the two fixed cylinders 31 with threaded blocks 36 on their surfaces, so that the two fixed cylinders 31 and the two mounting bolts 32 screw upward. Then, the corresponding two limit blocks 34 will be forced to move upward and thus separate from the inner wall of the adjusting cylinder 24. At this time, the two adjusting cylinders 24 are in a loose and rotatable state, so the use orientation of the two wire harness clips 5 can be adjusted. One wire harness can be clamped in parallel by the two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips 5. At this time, after confirming the orientation, first hold one wire harness clip 5 to prevent it from turning, and then rotate the fixed cylinder 31 above the corresponding wire harness clip 5 so that the fixed cylinder 31 is threaded and fixed to the mounting frame 21 again, and the mounting bolt 32 is threaded into the mounting frame 21 and the adjusting cylinder 24 again, thereby driving the limit block 34 connected to the mounting bolt 32 through the rotating block 33 to gradually penetrate downward into the adjusting cylinder 24 and gradually fit with the inner wall of the adjusting cylinder 24. Then, continue to apply a downward force, and then the limit block 34 and the silica gel pad 37 connected to the surface of the limit block 34 are completely in close contact with the inner wall of the adjusting cylinder 24, so as to generate a tightening limit force on the adjusting cylinder 24. The stability of the limit block 34 tightly against the inner wall of the adjusting cylinder 24 is further improved by the friction of the silica gel pad 37. At this time, the limit of the wire harness clip 5 is completed to prevent the wire harness clip 5 from shifting after the adjustment of the orientation. Similarly, the same operation is performed on the other wire harness clip 5, and the use orientation of the wire harness clip 5 can be adjusted at will, increasing the use orientation of the wire harness clip 5, improving the diversity of use, and improving the applicability. It should be noted that the limit block 34 is set in a funnel shape here, or the limit block 34 can be set in a square or regular pentagon shape, which can also improve the clamping and limiting effect. And the height positions of the two wire harness clips 5 can also be set staggered, one high and one low, so that wire harnesses at different heights can be clamped and fixed in different orientations, all of which do not affect the use and can be set as required.

[0041] Through the above technical solutions: 1. The rotation limit function of the limit slip ring 23 prevents the adjusting cylinder 24 from detaching from the fixed ring 22, and the adjustably rotatable adjusting cylinder 24 facilitates driving the corresponding wire harness clip 5 to adjust the use orientation. One wire harness can be clamped in parallel by two wire harness clips 5, or two wire harnesses can be clamped in parallel by adjusting the use orientation of the two wire harness clips 5; 2. The fixed cylinder 31 and the mounting bolt 32, both of which are threadedly connected to the mounting frame 21, facilitate controlling the up and down movement of the limit block 34. By controlling the upward movement of the limit block 34, it can be separated from the inner wall of the adjusting cylinder 24, and thus the use orientation of the wire harness clip 5 can be adjusted. By controlling the downward movement of the limit block 34 and the silicone pad 37 to closely adhere to the inner wall of the adjusting cylinder 24, the rotation of the adjusting cylinder 24 can be restricted, thereby preventing the wire harness clip 5 with the adjusted use orientation from shifting, preventing instability after the wire harness is installed, improving the overall flexibility of the wire harness clip 5 while also facilitating the fixation of the position of the wire harness clip 5.
