Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-5 , a telescopic advertising sign, including a sign mounting rod 1, an advertising sign 11 and a support pillar 2 are provided on the sign mounting rod 1, a protective plate 21 is provided on the support pillar 2, anti-bird spikes 22 are provided on the protective plate 21, a fixed plate 8 is provided below the sign mounting rod 1, mounting holes 81 and a bottom box 6 are provided on the fixed plate 8, a motor 61 and a switch 63 are provided in the bottom box 6, a first bevel gear 62 is provided on the motor 61, a second bevel gear 91 is meshed and connected to the first bevel gear 62, a main screw 9 is provided on the second bevel gear 91, a fixed cylinder 3 and a maintenance door 7 are provided on the bottom box 6, the fixed cylinder 3 is slidably connected to the sign mounting rod 1, a pointer arrow 4 is provided on the fixed cylinder 3, a pointer plate 5 is provided on the sign mounting rod 1, the protective plate 21 is made of tungsten steel material with high strength, and the protective plate 21 prevents larger hard objects from directly hitting the sign mounting rod 1.

[0028] Specifically, a scale ruler 51 is provided on the front end face of the pointer plate 5, and the end of the pointer arrow 4 facing the scale ruler 51 is a tip structure, enabling the staff to know the height dimension of the telescopic lifting of the advertising sign 11 in real time.

[0029] Furthermore, the first bevel gear 62 is fixedly arranged on the motor shaft of the motor 61, the second bevel gear 91 is fixedly sleeved on the outer wall of the main screw rod 9, the motor 61 and the switch 63 are electrically connected, and both the motor 61 and the switch 63 are connected to the nearby power supply box through buried wires. Three buttons are preset on the switch 63 to respectively realize the forward and reverse rotation and real-time stop of the motor shaft of the motor 61.

[0030] Furthermore, a threaded groove 12 is formed on the sign mounting rod 1, and the threaded groove 12 is in threaded connection with the main screw rod 9. The number of advertising signs 11 is four, and they are respectively installed on the four side surfaces of the sign mounting rod 1 through screws, improving the effective area of the advertisement display.

[0031] More specifically, the front view cross-section of the protection plate 21 is a conical structure, the anti-bird spikes 22 are overall in a sharp spike structure, there are nine groups of anti-bird spikes 22 arranged horizontally, and each group has ten arranged vertically. The anti-bird spikes 22 are made of hard alloy steel and are directly welded on the protection plate 21. The sharp spike-shaped anti-bird spikes 22 can prevent birds from directly standing on the top of the sign mounting rod 1.

[0032] Generally speaking, a maintenance opening 60 is formed at the right end of the bottom box 6. The side size of the maintenance door 7 is not less than the side size of the maintenance opening 60. Bolts 71 are provided on the maintenance door 7, and the maintenance door 7 is fixedly connected to the bottom box 6 through the bolts 71 by threading. At the same time, hinges are preset on the maintenance door 7, and the maintenance door 7 can be rotated and opened on the bottom box 6 through the preset hinges.

[0033] Finally, a guide sliding hole 32 is formed in the fixed cylinder 3. The guide sliding hole 32 vertically penetrates the fixed cylinder 3 and is rotatably sleeved on the main screw rod 9. A telescopic groove 31 is formed in the fixed cylinder 3, and the telescopic groove 31 is slidably sleeved on the sign mounting rod 1. The top view cross-sections of the telescopic groove 31 and the sign mounting rod 1 are rectangular structures, preventing the sign mounting rod 1 from rotating in the telescopic groove 31.

[0034] A sealing sleeve ring 311 is arranged at the upper opening of the telescopic groove 31. The sealing sleeve ring 311 is made of high-elastic NBR nitrile rubber and has high-elastic sealing performance, which can ensure the sliding connection sealing performance between the telescopic groove 31 and the sign mounting rod 1.

[0035] Working mode: When it is necessary to adjust the advertising sign 11 to extend or retract upward by a certain dimension distance, first rotate the bolt 71 counterclockwise and remove it, then rotate the maintenance door 7 to open it, and then press the right button on the switch 63 to drive the rotation of the motor shaft of the motor 61, which in turn drives the rotation of the first bevel gear 62. Through the meshing connection, it will drive the second bevel gear 91 and the main screw 9 to rotate counterclockwise at the same time. Through the screw drive with the thread groove 12, the sign mounting rod 1 can be driven to slide upward and extend or retract along the telescopic groove 31. At the same time, the pointer arrow 4 on the left side will indicate the dimension value on the scale 51 in real time. When the advertising sign 11 on the sign mounting rod 1 is extended or retracted upward to the required height position, press the middle button on the switch 63, and the motor 61 stops, realizing the electronically controlled telescopic lifting height dimension adjustment of the advertising sign 11. At the same time, the pointer arrow 4 can indicate the scale 51 in real time, enabling the staff to know the telescopic lifting height dimension of the advertising sign 11 in real time, avoiding the inaccuracy of manual telescopic adjustment, and overall improving the accuracy of the telescopic lifting height dimension of the advertising sign 11.

[0036] Moreover, by setting a support column 2 with a protective plate 21 at the top of the sign mounting rod 1 and arranging a bird spike 22 structure on the protective plate 21, it can be avoided that birds will stay on the top of the advertising sign 11 set in an open area and there will be a situation of bird droppings accumulation, greatly improving the anti-bird protection for the top of the advertising sign 11.

[0037] In addition, when it is necessary to regularly check and maintain the motor 61 and related transmission structures in the bottom box 6, first open the maintenance door 7, and then the motor 61 and related transmission structures in the bottom box 6 can be regularly checked and maintained through the maintenance port 60, which is very convenient.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
