Description

Technical Field

[0001] The utility model relates to a traffic facility, in particular to a hanging traffic sign board. Background Art

[0002] A suspended traffic sign is a sign that is installed at a higher position through an installation bracket to provide road information to pedestrians on the road. Graphics of different shapes and colors will be set as indicator symbols according to traffic regulations and road information to manage vehicle traffic and pedestrian travel.

[0003] At present, in order to facilitate the replacement of traffic signs and reduce the obstruction of the view of road participants by signs, lifting poles are also set up. The lifting of the lifting poles is controlled by motor drive to adjust the height of the signs to reduce the obstruction of the view. The use of displays on the signs also increases the convenience of replacing the signs.

[0004] For example, the Chinese patent with publication number CN220166741U discloses a hanging traffic sign. Through the switch dial set in the dial slide rail on the main rod, the lifting structure composed of the lowering rod and the bearing enables the lifting rod to control the motor to open, and the motor drives the transmission belt and the lifting shaft to rotate, so that flexible lifting and lowering can be achieved, and the position of the sign can be easily adjusted. The transmission structure composed of the lifting shaft and the main shaft enables the main shaft driven by the motor to drive the lifting shaft to achieve lifting.

[0005] When the hanging traffic sign is used outdoors for a long time, rainwater will penetrate into the motor body, causing a short circuit inside the motor, which is not conducive to the lifting shaft driving the sign to rise and fall, affecting the replacement of the traffic sign. Based on the above reasons, it is necessary to invent a traffic facility that can still replace the sign after long-term use outdoors. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a hanging traffic sign board, which achieves the purpose of waterproofing the hanging traffic sign board for outdoor use.

[0007] To achieve the above purpose, the technical solution of the utility model is as follows:

[0008] A hanging traffic sign includes a main pole, a motor and a lifting and rotating shaft arranged at the top of the main pole, a lifting rod arranged on the lifting and rotating shaft, a sign display arranged under the lifting rod, and a host.

[0009] The main rod, motor, main machine and lifting and rotating shaft are covered with the same waterproof device on their outer sleeves. The waterproof device includes a protective box fixed to the main rod and a protective cover arranged on the top of the protective box. A downwardly opening flow cavity is arranged between the protective cover and the protective box. A fan is arranged in the protective box to form a wind curtain at the flow cavity to isolate external rainwater and prevent rainwater from entering.

[0010] Preferably, the top of the protective cover is configured as an arc-shaped portion.

[0011] Preferably, a bracket connected to the protective cover is provided on the inner upper side of the protective box, and the bracket is in a ∏-shaped structure.

[0012] Preferably, a spacing frame is provided through the lower end of the protection box, and the spacing frame is located below the motor and the main machine.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the embodiments of the present disclosure are described in more detail in combination with the drawings of the embodiments below. Note: The described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] The hanging traffic sign provided by the embodiment of the utility model is used to solve the problem of water seepage and short circuit inside the motor 2 when the traffic sign is used outdoors. Figure 1 and 2 As shown, it includes a main pole 1, a motor 2 and a lifting and rotating shaft 4 arranged at the top of the main pole 1, a lifting pole 5 arranged on the lifting and rotating shaft 4, a sign display 3 arranged below the lifting pole 5, and a host 31. Through the same waterproof device 6 covered on the outside of the main pole 1, the motor 2, the host 31 and the lifting and rotating shaft 4, the electrical equipment used on the sign can be isolated inside the waterproof device 6, wherein the waterproof device 6 includes a protective box 61 fixed to the main pole 1 and a protective cover 62 arranged on the top of the protective box 61, the protective box 61 is covered on the outside of the above components, and the protective cover 62 covers the top of the above equipment and the protective box 61. A flow cavity with an opening downward is set between the protective cover 62 and the protective box 61, and a fan 63 is set in the protective box 61. When the fan 63 rotates and works, the air at the bottom of the protective box 61 can be sucked into the inside of the protective box 61, blocked by the protective cover 62, and passed into the flow cavity, forming a wind curtain at the flow cavity, so that the air is discharged to the outside of the waterproof device 6, and the external rainwater can be isolated to prevent rainwater from entering.

[0028] For better air discharge, such as Figure 5 As shown, the top of the protective cover 62 is arranged as an arc-shaped portion 621. The arrangement of the arc-shaped portion 621 on the inner side of the protective cover 62 facilitates the hot air inside the waterproof device 6 to be quickly discharged into the circulation cavity, thereby increasing the discharge rate of the hot air in the waterproof device 6; and the arrangement of the arc-shaped portion can reduce the accumulation or retention of external rain and snow on the protective cover 62, thereby avoiding load-bearing damage to the waterproof device 6 caused by rain and snow, and increasing the structural stability of the waterproof device 6.

[0029] In order to set the flow cavity between the protective cover 62 and the protective box 61, as shown in FIG. Figure 3 and 5 As shown, a bracket 611 connected to the protective cover 62 is provided on the inner upper side of the protective box 61, and the bracket 611 is a ∏-shaped structure. Through the setting of the bracket 611, the protective cover 62 can be suspended on the top of the protective box 61 to realize the setting of the flow cavity; and the protective cover 62 is connected to the protective box 61, and a triangular area can be formed between the bracket 611 and the protective cover 62, thereby increasing the connection firmness between the protective cover 62 and the protective box 61.

[0030] In order to prevent the rainwater at the bottom of the protection box 61 from being pumped into the protection box 61 when the fan 63 is working, Figure 2 and 3 As shown, a spacing frame 612 is provided through the lower end of the protection box 61, and the spacing frame 612 is located below the motor 2 and the host 31. The setting of the spacing frame 612 can improve the rainwater blocking effect inside the waterproof device 6, and the motor 2 and the host 31 can be kept away from the lower end opening of the protection box 61 through the spacing between the motor 2 and the host 31 and the lower end opening of the protection box 61, so as to avoid the entry of rainwater, and waterproof the lower end of the waterproof device 6.

[0031] Furthermore, if Figure 4 and 5 As shown, the lower end of the spacer frame 612 can also be expanded outward to expand the waterproof range of the spacer frame 612 to the lower end of the protection box 61, thereby preventing rainwater dripping from the lower end of the protection box 61 from being drawn into the protection box 61 and improving the waterproof effect.

[0032] In order to improve the heat dissipation effect of the fan 63, as Figure 4As shown, a detachable speed-increasing plate 613 is provided on the top of the spacer frame 612, and a plurality of through holes 614 are provided on the speed-increasing plate 613. When the speed-increasing plate 613 and the spacer frame 612 are installed, a buckle penetrating through the through hole 614 can be used to snap on the inner side of the speed-increasing plate 613 and fit the main rod 1. When the speed-increasing plate 613 is used, the air holes are used to discharge air, and the speed-increasing plate 613 can increase the air flow rate inside the windproof device and increase the heat dissipation rate by using the principle of increasing wind speed. When the fan 63 is working, the rotation of the fan 63 will draw the external cold air into the protective box 61, and the cold air will be accelerated after passing through a plurality of through holes 614, and then blown to the motor 2 and the main machine 31, taking away the heat on the surface of the motor 2 and the main machine 31, and finally, it will be discharged from the circulation cavity through the arc portion 621, so as to realize the internal circulation cooling of the waterproof device 6.

[0033] The multiple embodiments described above can all be regarded as preferred solutions for hanging signage. In order to better achieve the heat dissipation of the internal equipment of the protective box 61 by the fan 63, the fan 63 can be set on the upper side of the motor 2 and the host 31. When the fan 63 is working, the lower end of the fan 63 is the cold air area, and the upper end of the fan 63 is the hot air area. By setting the position of the fan 63, the heat dissipation of the sign can be increased, and the heat dissipation effect of the fan 63 can be improved.

[0034] Working principle: When the hanging traffic sign is used outdoors, the rotation of the fan 63 in the protective device can draw the air at the lower end of the isolation frame to the protective box 61, and the opening of multiple through holes 614 on the speed increasing plate 613 can increase the flow rate of the drawn air, so that the cold air can quickly enter the protective box 61. When the cold air contacts the motor 2, the main unit 31, and the lifting and rotating shaft 4 inside the protective box 61, the heat on its surface can be transferred to the air to form hot air, which is then output through the upward protective cover 62 at the outlet end of the fan 63. The hot air passes through the arc portion 621 and is discharged into the circulation cavity. The continuous operation of the fan 63 can form a downward-opening wind curtain between the protective cover 62 and the protective box 61, which waterproofs the outside of the waterproof device 6 while also dissipating heat, waterproofs the internal equipment of the waterproof device 6, ensures the normal use of the equipment, and facilitates the traffic sign to drive the lifting and rotating shaft 4 through the power of the motor 2, which can drive the lifting rod 5 and the sign display 3 to lift and lower, thereby extending its service life and use effect.

[0035] Of course, the above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
