Technical Field

[0001] This invention relates to the field of electrical maintenance equipment technology, and in particular to a sign and its mounting device. Background Technology

[0002] Most old outdoor utility poles lack signage, causing significant inconvenience for maintenance personnel during inspections. While some old poles now have signage, this is done manually, using wire or cable ties to attach the signs to the power grid lines. This presents considerable operational risks and is inefficient.

[0003] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a sign that can reduce the difficulty for maintenance personnel to hang the sign, greatly improve the efficiency of hanging the sign, and has a simple structure and low assembly difficulty.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

An upward-opening locking groove is provided between the flip hook and the sign panel. The bottom of the flip hook is connected to the sign panel via a reciprocating rotating assembly. A trigger rod is provided between the flip hook and the sign panel. The trigger rod is located at the opening of the locking groove. One end of the trigger rod is rotatably connected to the flip hook, and the other end of the trigger rod abuts against the sign panel.

[0007] In the aforementioned sign, connecting plates are respectively provided on the top two sides of the rear end face of the sign panel, a hinge seat is provided at the bottom of the connecting plate, a hinge groove is provided in the hinge seat, and a hinge part is provided at the bottom of the flip hook. The hinge part is rotatably connected to the hinge groove through the reciprocating rotation assembly.

[0008] In the aforementioned sign, the top of the connecting plate is provided with an upward-opening slot, and the top of the flip hook is provided with an upward-extending slot plate portion; the groove shape of the slot is adapted to the shape of the slot plate portion.

[0009] In the aforementioned sign, the flip hook is provided with a clearance groove along its length to avoid the trigger rod, and a rotating column is provided at the top of the clearance groove; one end of the trigger rod is provided with a biting part, and the biting part is provided with a biting groove that engages with the rotating column; the other end of the trigger rod is provided with a protrusion, and the connecting plate is provided with a positioning groove that engages with the protrusion.

[0010] In the aforementioned sign, the reciprocating rotating assembly includes a rotating pin and a torsion spring, the torsion spring being fitted onto the rotating pin; the hinge seat has first through holes on both sides of the hinge groove, the hinge part has a movable groove, and the hinge part has second through holes on both sides of the movable groove; the two first through holes, the hinge groove, the two second through holes, and the movable groove are connected by the rotating pin, and the torsion spring is located in the movable groove; one end of the torsion spring abuts against the bottom of the flip hook, and the other end of the torsion spring abuts against the sign panel; the sign panel has a limiting part below the torsion spring, the limiting part being used to support the free end of the torsion spring.

[0011] In the aforementioned sign, one end of the rotating pin is provided with two opposing support parts, and a pressure groove is formed between the two support parts. An inclined block that can engage with the opening of the second through hole is provided on the outside of the support part.

[0012] In the aforementioned sign, the flip hook comprises an integrally formed first arc plate and a second arc plate, the second arc plate being located at the bottom of the first arc plate; the ratio between the arc radius of the second arc plate and the arc radius of the first arc plate is in the range of 0.3-0.5.

[0013] This application also provides a corresponding hanging device for mounting the sign as described above. The hanging device includes a mounting clamp and an insulating rod. One end of the insulating rod is detachably connected to the mounting clamp, and the other end of the insulating rod is provided with an anti-slip sleeve. A clamp is rotatably connected to one side of the mounting clamp, and the clamp is provided with opposing clamping plates. An upward-opening clamping groove is formed between the two clamping plates.

[0014] In the hanging device, the opening of the clamping groove is a constricted opening that gradually narrows outward, and the ends of the two clamping plates are respectively provided with an expanding plate that bends outward toward the opening of the clamping groove.

[0015] The hanging device further includes a screw connection part. The mounting clamp is provided with a clamping groove that opens to one side and is adapted to the insulating rod. Locking plates are respectively provided on both sides of the groove opening. A threaded connection part is provided on the outer side of each locking plate. The screw connection part passes through the two locking plates in sequence and is threadedly connected to the threaded connection part. A rotating part is provided on the side of the mounting clamp away from the locking plate. The bottom of the clamp is rotatably connected to the rotating part.

[0016] Beneficial effects:

[0017] This invention provides a signboard with a panel that can be printed or affixed with different signage content. The content can be printed onto the panel using laser printing, ink printing, or other methods, or it can be affixed with stickers bearing the corresponding information. This allows maintenance personnel to quickly understand the basic condition of the utility pole and power distribution network based on the signboard. When installing the signboard, the two flip hooks are pre-flipped away from the signboard panel, opening the locking groove. Once the groove is open, the trigger rod is rotated to a horizontal position within the groove opening, with the other end of the trigger rod supporting the signboard panel, thus keeping both flip hooks open simultaneously. The process involves first lifting the sign panel from top to bottom onto the power distribution line using a mounting bracket, keeping the two flip hooks balanced, and gradually moving them closer to the power distribution line until the line is simultaneously engaged in both locking slots. When the line contacts and presses down on the two trigger rods, the end of the trigger rod that contacts the sign panel will loosen and swing downwards due to gravity. At this point, the flip hooks will lose the support of the trigger rods, and the reciprocating rotating assembly will cause the flip hooks to flip in the opposite direction towards the sign panel, so that the power distribution line is simultaneously clamped between the two flip hooks, thus completing the hanging action of the sign panel. This method greatly reduces the difficulty of hanging the sign panel and improves the hanging efficiency of maintenance personnel. Attached Figure Description

Detailed Implementation

[0026] This invention provides a sign and its mounting device. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0027] In the description of this invention, it should be understood that the terms "middle," "inner side," "outer side," etc., indicate the orientation or positional relationship of this invention based on the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0028] Please see Figures 1 to 7The present invention provides a sign, including a sign panel 1. A flip hook 2 is provided on both sides of the top of the rear end face of the sign panel 1. A locking groove 21 with an upward opening is provided between the flip hook 2 and the sign panel 1. The bottom of the flip hook 2 is connected to the sign panel 1 through a reciprocating rotating assembly 3. A trigger rod 4 is provided between the flip hook 2 and the sign panel 1. The trigger rod 4 is located at the opening of the locking groove 21. One end of the trigger rod 4 is rotatably connected to the flip hook 2, and the other end of the trigger rod 4 abuts against the sign panel 1.

[0029] In practical use, the sign panel 1 can be printed with or affixed with different signage content. The corresponding signage content can be printed on the sign panel 1 using laser printing, ink printing, or other methods. Alternatively, stickers with corresponding information can be affixed to the sign panel 1, allowing maintenance personnel to quickly grasp the basic information of the utility pole and distribution network lines based on the sign panel 1. When hanging the pole, the two flip hooks 2 are flipped away from the sign panel 1 beforehand, opening the locking groove 21. After the locking groove 21 is open, the trigger rod 4 is rotated to a position horizontally positioned at the opening of the locking groove 21, so that the other end of the trigger rod 4 supports the sign panel 1, keeping both flip hooks 2 open simultaneously. Then, the label panel 1 is lifted from top to bottom onto the power distribution line using a hanger, keeping the two flip hooks 2 balanced and gradually approaching the power distribution line until the power distribution line is simultaneously locked into the two locking slots 21. When the power distribution line contacts and presses down on the two trigger rods 4, the end of the trigger rod 4 that contacts the label panel 1 will loosen and swing downwards due to gravity. At this time, the flip hook 2 will lose the support of the trigger rod 4, and the reciprocating rotating component 3 will drive the flip hook 2 to flip in the opposite direction to the label panel 1, so that the power distribution line is simultaneously clamped in the two flip hooks 2, thereby completing the hanging action of the label panel 1. This method greatly reduces the difficulty of hanging the label panel 1 and improves the hanging efficiency of maintenance personnel.

[0030] like Figures 1 to 7 As shown, further, connecting plates 11 are respectively provided on the top two sides of the rear end face of the marking panel 1, and a hinge seat 12 is provided at the bottom of the connecting plate 11. A hinge groove 13 is provided in the hinge seat 12, and a hinge part 22 is provided at the bottom of the flip hook 2. The hinge part 22 is rotatably connected to the hinge groove 13 through the reciprocating rotation assembly 3. During assembly, the connecting plate 11 and the flip hook 2 are rotatably connected through the hinge groove 13 and the hinge part 22, and then the reciprocating swing action of the flip hook 2 is realized through the reciprocating rotation assembly 3.

[0031] like Figures 1 to 7As shown, the top of the connecting plate 11 is provided with an upward-opening slot 14, and the top of the flip hook 2 is provided with an upward-extending locking plate portion 23; the groove shape of the slot 14 is adapted to the shape of the locking plate portion 23; when the flip hook 2 flips towards the marking panel 1, the locking plate portion 23 will at least partially engage in the slot 14. After the locking plate portion 23 engages in the slot 14, it is restricted by the slot 14 and cannot move left or right, thereby avoiding the problem of the flip hook 2 swaying left and right and disengaging when it is in the hanging state, and improving the stability of the flip hook 2 during use.

[0032] like Figures 1 to 7 As shown, further, the flipping hook 2 is provided with a clearance groove 26 along its length to avoid the trigger rod 4, and a rotating post 27 is provided at the top of the clearance groove 26; one end of the trigger rod 4 is provided with a biting part 41, and the biting part 41 is provided with a biting groove 43 that engages with the rotating post 27; the other end of the trigger rod 4 is provided with a protrusion 42, and the connecting plate 11 is provided with a positioning groove 15 that engages with the protrusion 42; during assembly, the assembler presses the biting part 41 to make the biting part engage with the trigger rod 42. The engaging groove 43 engages with the rotating column 27. After the engaging part 41 is connected to the rotating column 27, the trigger rod 4 can swing around the rotating column 27 at a fixed point. The entire installation process is very simple and convenient. In addition, when the trigger rod 4 swings downward, the avoidance groove 26 avoids the trigger rod 4 from getting stuck in the locking groove 21 and affecting the entry of the distribution network line into the locking groove 21. Furthermore, by setting the protrusion 42 in conjunction with the positioning groove 15, the trigger rod 4 can be more stable in the supported state, avoiding the problem of the trigger rod 4 becoming loose during the hanging process.

[0033] In this embodiment, the protrusion 42 is semi-circular, and the positioning groove 15 is semi-circular.

[0034] like Figures 1 to 7As shown, further, the reciprocating rotation assembly 3 includes a rotating pin 31 and a torsion spring 32, the torsion spring 32 being fitted onto the rotating pin 31; the hinge seat 12 is provided with first through holes 17 on both sides of the hinge groove 13, the hinge part 22 is provided with a movable groove 28, and the hinge part 22 is provided with second through holes 29 on both sides of the movable groove 28; the two first through holes 17, the hinge groove 13, the two second through holes 29, and the movable groove 28 are connected by the rotating pin 31, and the torsion spring 32 is located in the movable groove 28; one end of the torsion spring 32 abuts against the bottom of the flip hook 2, and the other end of the torsion spring 32 abuts against the marking panel 1; the marking The identification panel 1 is provided with a limiting part 16 below the torsion spring part 32. The limiting part 16 is used to support the free end of the torsion spring part 32. In use, the spring characteristics of the torsion spring part 32 are used to realize the reciprocating swing action of the flip hook 2. When the flip hook 2 rotates away from the identification panel 1, it will drive one end of the torsion spring part 32 to rotate, thereby accumulating rotational force in the torsion spring part 32. If it is supported by the trigger rod 4, the torsion spring part 32 is in the triggered state. When the trigger rod 4 is released, the torsion spring part 32 will release the rotational force. One end of the torsion spring part 32 supports the surface of the identification panel 1, and the other end supports the bottom of the flip hook 2, and drives the flip hook 2 to rotate towards the identification panel 1, thereby completing the clamping action of the distribution network line.

[0035] like Figures 1 to 7 As shown, further, one end of the rotating pin 31 is provided with two opposing support portions 33, and a pressure groove 34 is formed between the two support portions 33. An inclined block 35 is provided on the outer side of each support portion 33, which can engage with the opening of the second through hole 29. This arrangement facilitates the disassembly and assembly of the rotating pin 31 by maintenance personnel. During installation, the end of the rotating pin 31 located at the support portion 33 will insert into the two first through holes 17, the hinge groove 13, the two second through holes 29, and the movable groove 28. During insertion, the inclined block 35... The two supporting parts 33 will bend and deform towards the pressure groove 34 under pressure. After the supporting parts 33 have completely passed through the hinge seat 12 and the hinge part 22, the supporting parts 33 will adaptively restore their deformation, so that the two inclined blocks 35 hook into the outer wall of either of the first through holes 17, thus completing the self-locking action of the rotating pin 31. When it is necessary to disassemble the rotating pin 31, the two supporting parts 33 need to be pressed to deform them until the inclined blocks 35 can pass through the first through hole 17 and the second through hole 29, so that it can be pulled out, thus completing the disassembly action of the rotating pin 31.

[0036] like Figures 1 to 7As shown, further, the flip hook 2 includes an integrally formed first arc plate 24 and a second arc plate 25, with the second arc plate 25 located at the bottom of the first arc plate 24; the ratio between the arc radius of the second arc plate 25 and the arc radius of the first arc plate 24 is in the range of 0.3-0.5; by setting the arc radius ratio of the second arc plate 25 and the second arc plate 25 to 0.3-0.5, the flip hook 2 can be made to have a continuous arc surface. Increasing the arc radius of the first arc plate 24 facilitates the entry of the distribution network line into the locking groove 21, while reducing... The radius of the arc of the second arc plate 25 can improve the stability of the distribution network line when it is locked in the locking groove 21. In addition, with this setting, the flip hook 2 can be adapted to cables with different diameters such as 70mm, 95mm, 120mm, 150mm, 185mm and 240mm. Preferably, the ratio between the radius of the arc of the second arc plate 25 and the radius of the arc of the first arc plate 24 is 0.4. When the ratio is 0.4, the flip hook 2 has the highest fit for all diameter cables when locked and the strongest clamping stability.

[0037] like Figures 1 to 7 As shown, this application also provides a corresponding mounting device for mounting the sign as described above. The mounting device includes a mounting clamp 5 and an insulating rod 6. One end of the insulating rod 6 is detachably connected to the mounting clamp 5, and the other end of the insulating rod 6 is provided with an anti-slip sleeve 61. A clamp 7 is rotatably connected to one side of the mounting clamp 5. The clamp 7 is provided with opposing clamping plates 71, and a clamping groove 72 with an upward opening is formed between the two clamping plates 71. In use, maintenance personnel can select an insulating rod 6 of appropriate length according to the height of the distribution network line from the ground, and connect one end of the corresponding insulating rod 6 to the mounting clamp 5. Then, the clamp 7 is used to clamp the lower end of the sign panel 1 until the lower end of the sign panel 1 is fully inserted into the clamping groove 72. At this time, the maintenance personnel can also adjust the clamp according to the position of the distribution network line. The angle of the clamp 7 is adjusted to reduce the difficulty of hanging the sign panel 1. After the sign panel 1 is pre-installed, the maintenance personnel hold one end of the anti-slip sleeve 61 of the insulating rod 6 and use the insulating rod 6 to lift the clamp 7 to below the distribution network line, so that the two flip hooks 2 approach the distribution network line at the same time. During the lifting process, the two flip hooks 2 should be kept on the same horizontal line as much as possible until the distribution network line is inserted into the locking groove 21. When the distribution network line contacts and presses down the trigger rod 4, the end of the trigger rod 4 that contacts the sign panel 1 will loosen and swing downward under the influence of gravity. At this time, the two flip hooks 2 will lose the support of the trigger rod 4 at the same time. The reciprocating rotating component 3 will drive the flip hooks 2 to flip in the opposite direction of the sign panel 1 until the flip hooks 2 complete the closing action, so that the distribution network line is clamped in the locking groove 21, thereby completing the hanging action of the sign.

[0038] like Figures 1 to 7As shown, the opening of the clamping groove 72 is a gradually narrowing shape, and the ends of the two clamping plates 71 are respectively provided with expanding plates 73 that bend outwards from the opening of the clamping groove 72. By setting the opening of the clamping groove 72 to a narrow shape, it is easier to clamp the marking panel 1. Furthermore, by setting the ends of the clamping plates 71 to expanding plates 73 that bend outwards, the width at the entrance of the clamping groove 72 can be increased, which plays a guiding role for the marking panel 1, making the connection between the marking panel 1 and the clamp 7 smoother, and eliminating the need for maintenance personnel to calibrate the position between the clamp 7 and the marking panel 1.

[0039] like Figures 1 to 7 As shown, the mounting device further includes a screw connection part 54. The mounting clamp 5 is provided with a clamping groove 51 that opens to one side and is adapted to the insulating rod 6. Locking plates 52 are respectively provided on both sides of the groove opening of the clamping groove 51. A threaded connection part 53 is provided on the outer side of any locking plate 52. The screw connection part 54 passes through the two locking plates 52 in sequence and is threadedly connected to the threaded connection part 53. A rotating part 55 is provided on the side of the mounting clamp 5 away from the locking plate 52. The bottom of the clamp 7 is rotatably connected to the rotating part 55. The clamping groove 51, locking plate 52, threaded connection part 53 and screw connection part 54 form a clamping structure, realizing the detachable connection between the insulating rod 6 and the mounting clamp 5. This allows maintenance personnel to select different insulating rods 6 according to the mounting height, improving the flexibility of the mounting device during use. In addition, the rotating part 55 is used to adjust the angle of the clamp 7, allowing the mounting device to cope with more different usage scenarios.

[0040] It should be noted that the rotating part 55 can be an existing damping shaft, torsion screw, or other rotating device.

[0041] In summary, the sign panel 1 can be printed with or affixed with different signage content. The corresponding signage content can be printed on the sign panel 1 using laser printing, ink printing, or other methods. Alternatively, the signage content can be attached to the sign panel 1 by affixing stickers with corresponding information. This allows maintenance personnel to quickly understand the basic situation of the utility pole and distribution network lines based on the sign panel 1. When installing the pole, the two flip hooks 2 are flipped away from the sign panel 1 beforehand, causing the locking groove 21 to open. After the locking groove 21 is open, the trigger rod 4 is rotated to a position horizontally positioned at the opening of the locking groove 21, so that the other end of the trigger rod 4 supports the sign panel 1, keeping both flip hooks 2 open simultaneously. Then, the label panel 1 is lifted from top to bottom onto the power distribution line using a hanger, keeping the two flip hooks 2 balanced and gradually approaching the power distribution line until the power distribution line is simultaneously locked into the two locking slots 21. When the power distribution line contacts and presses down on the two trigger rods 4, the end of the trigger rod 4 that contacts the label panel 1 will loosen and swing downwards due to gravity. At this time, the flip hook 2 will lose the support of the trigger rod 4, and the reciprocating rotating component 3 will drive the flip hook 2 to flip in the opposite direction to the label panel 1, so that the power distribution line is simultaneously clamped in the two flip hooks 2, thereby completing the hanging action of the label panel 1. This method greatly reduces the difficulty of hanging the label panel 1 and improves the hanging efficiency of maintenance personnel.
