Description

Technical Field

[0001] The utility model relates to the technical field of signboards, in particular to an installation structure of a large signboard. Background Art

[0002] Traffic signs are graphic symbols that display traffic regulations and road information. They can express traffic regulations in a vivid, specific and concise manner, and at the same time express content that is difficult to describe in words. They are used to manage traffic, indicate driving directions, ensure smooth roads and safe driving, and can intuitively feedback the display conditions on the signs to viewers.

[0003] The existing signboard installation structure mainly fixes the installation rod and the base on the designated ground by bolts and nuts, and uses a clamp to fix the signboard on the installation rod. Although this installation structure can fix the signboard, when the signboard is repaired and replaced, the operator can only be transported to the signboard by a ladder to carry out the work, which has a certain risk factor and is difficult to maintain and replace the signboard. In addition, due to the large area of ​​the signboard, when encountering strong winds, the signboard is prone to deflection, thereby affecting the viewing of the signboard. Utility Model Content

[0004] In response to the shortcomings of existing signboard installation structures, the utility model provides a large-scale signboard installation structure, which has the advantages of being able to perform daily maintenance and replacement of the signboard installation structure by lifting, thereby improving the convenience of signboard installation, preventing the signboard from deflecting in windy weather, and improving the stability of the signboard, solving technical problems such as complicated signboard installation structure, inconvenient maintenance and replacement, and instability in windy weather.

[0005] The utility model provides the following technical solution: a large signboard installation structure, including a base, and also including:

[0006] The mounting rod is fixedly mounted on the middle part of the top surface of the base, a fixing sleeve is sleeved with bolts on the outer surface of the mounting rod, and a sign is fixedly mounted on the fixing sleeve through a fixing rod.

[0007] Preferably, the interior of the mounting rod includes:

[0008] A cylindrical cavity is provided inside the mounting rod;

[0009] The slide groove is arranged inside the installation rod and located at the left and right sides of the cylindrical cavity. The slide groove penetrates the side wall of the installation rod located at the outer circle of the cylindrical cavity.

[0010] Preferably, the interior of the cylindrical cavity includes:

[0011] The screw is arranged inside the cylindrical cavity, and the top end and the bottom end of the screw are rotatably connected to the top surface and the bottom surface of the inner cavity of the cylindrical cavity respectively.

[0012] Preferably, the interior of the cylindrical cavity further includes:

[0013] A stator, fixedly connected to the lower part of the inner cavity of the cylindrical cavity;

[0014] A stator coil is wound on the stator;

[0015] The rotor is fixedly sleeved on the outer surface of the screw and is located on the inner side of the stator.

[0016] Preferably, the fixing hoop comprises:

[0017] A sleeve, fixedly sleeved on the inner ring side wall of the fixed sleeve, and the sleeve is slidably sleeved on the outer surface of the mounting rod;

[0018] The transverse plate is fixedly connected to the middle part of the inner cavity of the sleeve, the transverse plate is slidably engaged in the slide groove, and the transverse plate and the screw rod are sleeved via threaded transmission.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. By designing the slide, screw, stator, stator coil, rotor, sleeve and cross plate, when the sign needs to be maintained or replaced, the operator only needs to connect the stator coil to the negative pole of the DC power supply, so that the rotor drives the screw to rotate counterclockwise. At this time, the rotation of the screw will prompt the cross plate to move downward, and the cross plate will drive the sleeve downward, causing the sleeve to drive the fixed sleeve and the sign to move downward, so as to achieve the descent of the sign, which is convenient for the operator to maintain or replace the sign, greatly reducing the difficulty of sign maintenance, thereby improving the convenience of the sign installation structure.

[0021] 2. When the signboard is maintained or replaced, just connect the stator coil to the positive pole of the DC power supply. The magnetic field generated by the stator will cause the rotor to rotate clockwise, thereby using the rotor to drive the screw to rotate clockwise, so that the cross plate drives the sleeve and the signboard to move up. The threaded cooperation between the screw and the cross plate makes the signboard more stable and reliable when it is in the air. The rotation of the screw and the design of the cross plate sleeve make it easier to lift the signboard.

[0022] 3. By designing the sleeve and the cross plate, since the signboard is installed on the sleeve through a fixed sleeve, and the cross plate inside the sleeve is stuck in the slide groove, when the signboard is blown by strong winds, the slide groove limits the cross plate, so that the wind cannot blow the signboard to deflect, which greatly improves the stability of the signboard in windy weather.

[0030] See also Figure 1-Figure 4 A cylindrical cavity 21 is defined inside the mounting rod 2 .

[0031] Slide grooves 22 are provided on the left and right sides of the cylindrical cavity 21 inside the installation rod 2 , and the slide grooves 22 penetrate the side wall of the installation rod 2 located at the outer circle of the cylindrical cavity 21 .

[0032] See also Figure 1-Figure 4 A screw rod 23 is disposed inside the cylindrical cavity 21 , and the top and bottom ends of the screw rod 23 are rotatably connected to the top and bottom surfaces of the inner cavity of the cylindrical cavity 21 , respectively, to ensure that the screw rod 23 can rotate inside the cylindrical cavity 21 .

[0033] See also Figure 1-Figure 4 A stator 24 is fixedly installed at the lower part of the inner cavity of the cylindrical cavity 21.

[0034] A stator coil 25 is wound on the stator 24 , and a connector for connecting to an external power source is provided on the rotor coil 25 .

[0035] A rotor 26 is fixedly sleeved on the outer surface of the screw 23 and located inside the stator 24 . The rotor 26 rotates through the cooperation between the stator 24 and the stator coil 25 , thereby driving the screw 23 to rotate through the rotor 26 .

[0036] See also Figure 1-Figure 4 A sleeve 31 is fixedly sleeved on the inner ring side wall of the fixed sleeve hoop 3, and the sleeve 31 is slidably sleeved on the outer surface of the mounting rod 2, so that the sleeve 31 slides on the outer surface of the mounting rod 2, thereby driving the signboard 4 to move up and down.

[0037] A transverse plate 32 is fixedly welded to the middle part of the inner cavity of the sleeve 31. The transverse plate 32 is slidably engaged in the slide groove 22, and the transverse plate 32 and the screw rod 23 are connected by a threaded transmission sleeve to ensure that when the screw rod 23 rotates, the transverse plate 32 is moved by the limit of the slide groove 22. When the screw rod 23 rotates clockwise, the transverse plate 32 moves up, and when the screw rod 23 rotates counterclockwise, the transverse plate 32 moves down.

[0038] Working principle: When the signboard 4 in the air needs to be maintained or replaced, the operator only needs to connect the stator coil 25 to the negative pole of the DC power supply, so that the magnetic field generated by the stator 24 causes the rotor 26 to rotate counterclockwise, and the rotor 26 drives the screw 23 to rotate counterclockwise, and the rotation of the screw 23 causes the cross plate 32 to move downward, and the cross plate 32 drives the sleeve 31 to move downward, and the sleeve 31 drives the fixed sleeve 3 and the signboard 4 to move downward, thereby realizing the lifting of the signboard 4, making the maintenance or replacement of the signboard 4 more convenient. After the maintenance or replacement of the signboard 4 is completed, the operator only needs to connect the stator coil 25 to the DC power supply. The positive pole of the DC power source is connected to the stator 24, so that the magnetic field generated by the stator 24 causes the rotor 26 to rotate clockwise, thereby driving the screw 23 to rotate clockwise, causing the cross plate 32 to drive the sleeve 31, the fixed sleeve 3 and the signboard 4 to move upward, making the overall installation structure of the signboard 4 simpler. Secondly, due to the arrangement of the cross plate 32 and the sleeve 31, when the signboard 4 encounters strong winds, the cross plate 32 is stuck by the slide groove 22, so that the strong wind cannot blow the signboard 4 to deflect, thereby avoiding the signboard 4 being blown and deflected by the strong wind to affect the viewing, improving the stability of the signboard 4, and ensuring that the signboard 4 can be replaced to feed back the sign information to the viewer.
