Description
Technical Field
[0001] The present application relates to the technical field of identification devices, and particularly to an adjusting device for airport signs. Background Art
[0002] An adjusting device for airport signs is a facility in an airport for installing signs indicating position directions or prompting information, usually set at prominent positions.
[0003] The existing adjusting devices for airport signs generally adopt a hanging design and are installed on the ceiling. Such a hanging adjusting device generally includes a light box and a hanging rod. A light-emitting lamp tube is provided inside the light box. The top of the light box is connected to the ceiling through the hanging rod, and signs can be fixed on the four side boxes of the light box by screws.
[0004] However, since the light box body is suspended by the hanging rod at a relatively high position from the ground, and the signs on the light box need to have the screws on the signs disassembled and assembled when being replaced, it causes workers to frequently move ladders to disassemble and assemble the screws and replace the signs when performing the work of replacing signs, thus making the work of replacing signs of the adjusting device for airport signs rather cumbersome.
[0005] In view of this, there is a need to provide an adjusting device for airport signs. Summary of the Utility Model
[0006] In order to solve the problem that the work of replacing signs of the existing adjusting device for airport signs is rather cumbersome, the present application provides an adjusting device for airport signs.
[0007] The present application provides an adjusting device for airport signs, adopting the following technical solutions: including a top plate, a light box and a pair of signs. The top plate is connected to the ceiling, and a rotating shaft is provided at the bottom of the top plate;
[0008] The top of the light box is rotatably connected to the rotating shaft. Installation through grooves are respectively opened on both sides of the light box extending along the length direction. Each installation through groove runs through the entire length direction of the light box, and limiting edges extending towards the middle of the light box are provided on the bottom wall and the top wall of each installation through groove;
[0009] The signs correspond to the installation through grooves one by one. Each sign can be inserted into the corresponding installation through groove and be abutted between the limiting edge and the side wall of the installation through groove.
[0010] By adopting the above technical solution, when two signs need to be replaced simultaneously, the worker can first place the ladder on one side of the light box extending along the length direction, then climb to a position where the light box can be reached and rotate the light box around the rotating shaft so that the side of the light box extending along the width direction faces the worker. Then, the two old signs are respectively pulled out from the ends of the two installation through slots close to the worker, and the new signs are inserted into the installation through slots. Finally, the light box is rotated back to its original position, and the replacement of the two signs can be easily achieved, so that the worker does not need to move the ladder frequently, thus making the work of replacing signs of the airport sign adjusting device time-saving and labor-saving.
[0011] Specifically, a pair of baffles are provided at the bottom of the top plate. The pair of baffles are oppositely arranged with the rotating shaft as the center. The two baffles correspond to the two sides of the light box extending along the width direction one by one. When one end of the installation through slot faces the baffle, the distance between the slot and the baffle is less than the size of the sign along the length direction of the installation through slot.
[0012] By adopting the above technical solution, when the light box rotates to a state where the two ends of the installation through slot face the corresponding baffles, the two baffles can block the signs in the installation through slot, so that the signs are not easily dropped from the two ends of the installation through slot due to vibration or other reasons and injure pedestrians or objects near the airport sign adjusting device.
[0013] Further, a threaded section, a smooth rod section and an abutting ring are sequentially arranged on the shaft body of the rotating shaft along the axial direction. A rotating hole is opened at the top of the light box, and a connecting hole is opened on the top plate. The threaded section of the rotating shaft can sequentially pass through the rotating hole and the connecting hole and be screwed with a nut. The nut can abut against the top of the top plate. The rotating hole is sleeved on the smooth rod section of the rotating shaft, and the side of the abutting ring facing the top plate abuts against the inner wall of the light box.
[0014] By adopting the above technical solution, the rotating shaft can be suspended on the top plate through the cooperation of the threaded section and the nut, and the light box can be suspended on the rotating shaft and rotate around the smooth rod section.
[0015] Further, a spring is sleeved on the rotating shaft. The spring is located between the abutting ring and the inner wall of the light box and can apply a force to the light box to make it close to the top plate.
[0016] By adopting the above technical solution, the spring can apply a force to the light box to make it close to the top plate, so that the light box is not easily affected by factors such as wind and rotates spontaneously around the rotating shaft.
[0017] Further, a counterbore adapted to the nut is opened at the top of the top plate, and a gasket is provided between the nut and the bottom wall of the counterbore.
[0018] By adopting the above technical solution, the gasket can share the pressure applied by the nut to the top plate.
[0019] Further, a supporting plate extending in the horizontal direction is provided at the bottom of the baffle, and the supporting plate can abut against the bottom of the light box.
[0020] By adopting the above technical solution, the supporting plate and the abutting ring can share the weight of the light box together, so that the connection between the light box and the abutting ring is not easily damaged due to excessive pressure.
[0021] Further, a clamping convex block is provided on the top plate surface of the supporting plate, and a clamping groove is opened at the bottom of the light box. When one end of the installation through groove faces the baffle, the clamping convex block can be inserted into the clamping groove.
[0022] By adopting the above technical solution, the clamping groove and the clamping convex block can cooperate to limit the rotation of the light box, so that the light box will not rotate spontaneously around the rotating shaft due to factors such as being blown by the wind.
[0023] Specifically, a lamp tube for emitting light is provided inside the light box.
[0024] By adopting the above technical solution, when the whole or part of the sign adopts a light-transmitting design, the light emitted by the lamp tube can illuminate these light-transmitting designs, making the sign more beautiful and eye-catching.
[0025] In summary, the present application includes the following beneficial technical effects:
[0026] It includes a top plate, a light box and a pair of signs. The top plate is connected to the ceiling, and a rotating shaft is provided at the bottom of the top plate; the top of the light box is rotatably connected to the rotating shaft, and installation through grooves are opened on both sides of the light box extending along the length direction. Each installation through groove runs through the entire length direction of the light box, and limiting ribs extending towards the middle of the light box are provided on the bottom wall and the top wall of each installation through groove; the signs correspond to the installation through grooves one by one, and each sign can be inserted into the corresponding installation through groove and abutted between the limiting rib and the side wall of the installation through groove. When it is necessary to replace two signs at the same time, the worker can first place the ladder on one side of the light box extending along the length direction, then climb to a position where the light box can be reached and rotate the light box around the rotating shaft so that one side of the light box extending along the width direction faces himself. Then, the two old signs are respectively pulled out from the ends of the two installation through grooves close to himself, and the new signs are inserted into the installation through grooves. Finally, the light box is rotated back to its original position, and the replacement of the two signs can be easily realized, so that the worker does not need to move the ladder frequently, making the work of replacing signs of the airport sign adjustment device time-saving and labor-saving.

When the whole or part of the signboard 3 adopts a light-transmitting design, the light emitted by the lamp tube 22 can illuminate these light-transmitting designs, so that the signboard 3 is more beautiful and eye-catching; mounting through grooves are provided on both sides of the light box 2 extending along the length direction, each mounting through groove runs through the entire length direction of the light box 2, and limiting edges 21 extending towards the middle of the light box 2 are provided on the bottom wall and the top wall of each mounting through groove; the signboards 3 correspond to the mounting through grooves one by one, and each signboard 3 can be inserted into the corresponding mounting through groove and abutted between the limiting edge 21 and the side wall of the mounting through groove.
[0033] With the above settings, when it is necessary to replace two signs 3 simultaneously, the worker can first place the ladder on one side of the light box 2 extending along the length direction, then climb to a position where the light box 2 can be reached and rotate the light box 2 around the rotating shaft 11 so that the side of the light box 2 extending along the width direction faces the worker. Then, the two old signs 3 are respectively pulled out from the ends of the two installation through slots close to the worker, and the new signs 3 are inserted into the installation through slots. Finally, the light box 2 is rotated back to its original position, and the replacement of the two signs 3 can be easily achieved, so that the worker does not need to move the ladder frequently, thereby making the work of replacing the signs 3 of the airport sign adjustment device time-saving and labor-saving.
[0034] Figure 3 is a schematic cross-sectional view taken along the central axis of the light box of an airport sign adjustment device according to the present application. Refer to Figure 2 and Figure 3 , a pair of baffles 12 are provided at the bottom of the top plate 1. The pair of baffles 12 are arranged oppositely with the rotating shaft 11 as the center. The two baffles 12 correspond one by one to the two sides of the light box 2 extending along the width direction. When one end of the installation through slot faces the baffle 12, the distance between the slot and the baffle 12 is less than the dimension of the sign 3 along the length direction of the installation through slot. When the light box 2 rotates to a state where both ends of the installation through slot face the corresponding baffles 12, the two baffles 12 can block the sign 3 in the installation through slot, so that the sign 3 is not easily dropped from the two ends of the installation through slot due to vibration or other reasons and injure pedestrians or objects near the airport sign adjustment device.
[0035] Figure 4 is Figure 3 a schematic enlarged view of area B in Figure 3 and Figure 4 , a threaded section 111, a smooth rod section 112, and an abutting ring 113 are sequentially provided on the shaft body of the rotating shaft 11 along the axial direction. A rotating hole is opened at the top of the light box 2, and a connection hole is opened on the top plate 1. The threaded section 111 of the rotating shaft 11 can sequentially pass through the rotating hole and the connection hole and be screwed with the nut 5. The nut 5 can abut against the top of the top plate 1. The rotating hole is sleeved on the smooth rod section 112 of the rotating shaft 11, and the side of the abutting ring 113 facing the top plate 1 abuts against the inner wall of the light box 2, so that the rotating shaft 11 can be suspended on the top plate 1 through the cooperation of the threaded section 111 and the nut 5, and the light box 2 can be suspended on the rotating shaft 11 and rotate around the smooth rod section 112; a spring 114 is also sleeved on the rotating shaft 11. The spring 114 is located between the abutting ring 113 and the inner wall of the light box 2 and can apply a force to the light box 2 to make it close to the top plate 1, so that the light box 2 is not easily affected by factors such as wind and rotates around the rotating shaft 11 spontaneously.
