[0002] Signs are signs built on the sides of roads or in green belts to facilitate citizens' travel, provide guidance, and identify directions. Road signs are generally composed of sign panels, brackets, and fixings.

[0003] When the road name and other conditions change, or the signboard ages due to age, the signboard needs to be replaced. However, most signs are metal plates and are directly fixed on the poles. This also means that when replacing the signboard, it is necessary to either climb up to the signboard to dismantle it, and when dismantling it, it is necessary to drill screws and position screws again, which is troublesome and inconvenient. In addition, there are high safety hazards when constructing at high places. Or, if the pole is laid down to dismantle the signboard, it is necessary to call for lifting equipment to lay down and stand up the pole, which is also inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 7 A sign that is easy to replace includes a column 1, a base 22 is installed at the bottom of the column 1, and a through hole 24 is opened along the edge of the base 22. In actual use, anchor bolts and other fixing parts can be placed in the through hole 24, so that the column 1 can be installed on a table such as the ground.

[0029] like Figure 1 As shown, a plurality of reinforcing plates 23 arranged at intervals are vertically installed on the top of the base 22 , and the side surfaces of the reinforcing plates 23 are fixed to the column 1 to enhance the supporting strength of the column 1 .

[0030] like Figure 2 and Figure 6 As shown, the column 1 is a hollow support tube, and a strip groove 2 is provided on one side of the column 1 along the length direction of the column 1, and the strip groove 2 runs through the side of the column 1; a screw rod 3 is provided in the strip groove 2, and the end of the screw rod 3 is rotatably connected to the end of the strip groove 2, and a driving mechanism for driving the screw rod 3 to rotate is connected to the bottom of the screw rod 3, wherein, as shown in FIG. Figure 7As shown, the driving mechanism includes a worm wheel 17, which is coaxially fixed on the bottom of the screw rod 3. A worm 18 is meshed on the side of the worm wheel 17. The end of the worm 18 is rotatably mounted on the inner wall of the column 1, and one end of the worm 18 passes through the column 1 and is connected to a rotating handle 19. Rotating the rotating handle 19 can control the rotation of the screw rod 3. In actual use, the transmission structure of the worm 18 and the worm wheel 17 allows the rotation of the rotating handle 19 to provide power for the rotation of the screw rod 3, and the worm 18 and the worm wheel 17 can also lock the screw rod 3, so that the screw rod 3 will not rotate accidentally without the function of the rotating handle 19.

[0031] Furthermore, a frame 14 is installed along the edge of the strip groove 2, and slide rails 15 are installed along the length direction of the strip groove 2 on both sides of the inside of the frame 14, and a slide groove 16 is set on the side of the movable seat 4, and the movable seat 4 is slidably connected to the slide rail 15 through the slide groove 16, providing a guiding effect for the lifting and lowering of the movable seat 4, making the lifting and lowering of the movable seat 4 more stable.

[0032] In order to protect the rotating handle 19 and prevent the rotating handle 19 from being accidentally touched and causing accidental rotation of the screw rod 3, a box body 20 is installed on the side of the column 1, and the rotating handle 19 is placed in the box body 20, and a box cover 21 is provided on the other side of the box body 20. One side of the box cover 21 is hinged on the box body 20, and the other side of the box cover 21 is connected to the box body 20 through a lock. When the sign needs to be replaced, the lock on the box cover 21 can be opened, and then the box cover 21 can be turned open, and the rotating handle 19 can be held to rotate, thereby driving the screw rod 3 to rotate.

[0033] like Figure 2 and Figure 6 As shown, at least one moving seat 4 is threadedly connected to the screw rod 3, and one end of the moving seat 4 passes through the strip groove 2 and is connected to the back plate 5. Figure 3 and Figure 4 As shown, a support plate 6 is vertically installed at the bottom of the other side of the back plate 5, and a limit plate 7 is vertically installed on both sides of the back plate 5, the bottom of the limit plate 7 is correspondingly connected to the support plate 6, and an indicator board 9 is vertically placed above the support plate 6, and a "U"-shaped support structure is formed between the limit plate 7 and the support plate 6 to support the indicator board 9;

[0034] like Figure 3 and Figure 4As shown, a cover plate 10 is provided on the side of the sign 9 away from the back plate 5. The cover plate 10 is a transparent plate, which is one of a transparent plastic plate, a transparent acrylic plate, and a transparent glass plate. A strip plate 11 with an end bent downward in an "L" shape is installed on the top of the cover plate 10, and the cover plate 10 corresponds to the top of the back plate 5, and the end of the cover plate 10 corresponds to the top of the limit plate 7 and is fixed by a fastener, which is a bolt or a screw. After the sign 9 is placed on the back plate 5, the cover plate 10 is taken out and the strip plate 11 is placed on the back plate 5, so that the cover plate 10 can cover the sign 9, and cooperate with the back plate 5 to wrap the sign 9. At this time, the end of the strip plate 11 will cover the top of the limit plate 7, and finally the fastener is taken out and installed on the end of the strip plate 11, so that the cover plate 10 can be fixed on the back plate 5.

[0035] In order to facilitate the placement of the cover plate 10 on the back plate 5, a limiting seat 8 is installed on the limiting plate 7 away from the back plate 5, and limiting grooves 13 corresponding to the limiting seat 8 are installed at both ends of the side of the cover plate 10 close to the back plate 5. When placing the cover plate 10, the cover plate 10 can be vertically lowered from the top of the back plate 5. When the strip plate 11 is placed on the top of the back plate 5, the cover plate 10 will be stabilized due to the corresponding relationship between the limiting seat 8 and the limiting groove 13, so as to facilitate the subsequent fixation of fasteners.

[0036] Specifically, when the sign 9 needs to be replaced, the sign 9 can be lowered from the top of the column 1 by shaking the rotating handle 19, and then the fasteners on the strip plate 11 are unscrewed and the cover plate 10 is lifted up to expose the sign 9. Then the sign 9 can be replaced. After the replacement is completed, the cover plate 10 is placed back to the original position and the fasteners are screwed on, and then the rotating handle 19 is turned again to raise the sign 9 back to the top of the column 1.

[0037] It should be noted that if Figure 5 As shown, the front projection of the back plate 5 is located inside the cover plate 10, and both the back plate 5 and the cover plate 10 are arc panels, and the concave surface of the back plate 5 and the concave surface of the cover plate 10 are arranged opposite to each other. When the wind in the environment blows head-on onto the back plate 5 or the cover plate 10, it can disperse outward along the arc surface, thereby guiding the wind to the side, thereby improving the wind resistance of the sign.

[0038] Since the sign is exposed to the environment, a baffle 12 is installed on the side of the strip plate 11 away from the cover plate 10. The baffle 12 corresponds to the back plate 5 and covers the gap between the strip plate 11 and the back plate 5, thereby preventing rainwater from entering between the back plate 5 and the cover plate 10 through the gap between the strip plate 11 and the back plate 5.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
