Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic facilities, in particular to a pedestrian crossing device which is easy to install. Background Art
[0002] The safety of pedestrian crossing is very important. At present, many crosswalks are equipped with zebra crossings instead of traffic lights in order to improve traffic efficiency. Therefore, under normal circumstances, drivers should slow down before the zebra crossing and brake and avoid pedestrians in time. However, near the slippery belt in the middle of the road, it is difficult to see pedestrians crossing from the other side of the road in time due to the obstruction of the green belt and the obstruction of vision at night. Some pedestrians cross the road with the mentality that the driver will definitely let them cross, and the driver cannot see them, which will inevitably cause traffic accidents. Traditional pedestrian crossing devices are only equipped with corresponding warning lights, but these lights can only serve to remind people to slow down, and cannot indicate the specific situation of pedestrians crossing the street. Therefore, in order to solve these problems, we propose a pedestrian crossing device that is easy to install. Utility Model Content
[0003] The main purpose of the utility model is to provide a pedestrian crossing device that is easy to install and can effectively solve the problems in the background technology.

[0006] Preferably, the pre-installation seat includes a fixed base plate, a fixing hole, a mounting ring, a sub-spiral pattern, an L-shaped clip and a locking screw hole. The mounting ring and the fixing hole are both arranged on the surface of the fixed base plate. There are five fixing holes and four mounting rings. The fixing holes and the mounting rings are evenly and alternately arranged on the surface of the fixed base plate. A locking screw hole is provided on the surface of the fixed base plate near one end, and L-shaped clips are fixedly installed on the front and rear surfaces of the fixed base plate.
[0007] Preferably, the safety warning structure includes a support pole, a light box, a warning light, an extended mounting rod and an infrared human body sensing controller. The light box is fixedly mounted on the upper end of the support pole, and warning lights are fixedly mounted on both sides of the light box. The upper surface of the light box is fixedly mounted with an extended mounting rod, and the lower surface of the extended mounting rod is fixedly mounted with an infrared human body sensing controller near one end. A DC power supply and a single-chip microcomputer are provided inside the extended mounting rod.
[0008] Preferably, the DC power supply is powered by a mains power connection, and the surfaces of the dividing rod and the support rod are provided with a female spiral pattern near the lower end, and the dividing rod is provided with three female spiral patterns. The dividing rod and the support rod are both screwed into the sub-spiral patterns at the corresponding positions through the female spiral patterns and fixedly installed with the pre-installed seat.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1-4 As shown, a pedestrian crossing device that is easy to install includes a pre-installed base 1, a safety warning structure 2 is screw-fixedly installed on the upper surface of the pre-installed base 1, a partition rod 3 is screw-fixed on the upper surface of the pre-installed base 1 on one side of the safety warning structure 2, and a protective structure 4 is snap-fitted onto the surface of the pre-installed base 1;
[0020] The pre-installed seat 1 includes a fixed base plate 11, a fixing hole 12, a mounting ring 13, a sub-helical pattern 14, an L-shaped card strip 15 and a locking screw hole 16. The mounting ring 13 and the fixing hole 12 are both arranged on the surface of the fixed base plate 11. There are five fixing holes 12 and four mounting rings 13. The fixing holes 12 and the mounting rings 13 are evenly and alternately arranged on the surface of the fixed base plate 11. A locking screw hole 16 is opened on the surface of the fixed base plate 11 near one end. The front and rear surfaces of the fixed base plate 11 are fixedly installed with L-shaped card strip 15; the safety warning structure 2 includes a support rod 21, a light box 22, a warning light 23, an extended mounting rod 24 and an infrared human body sensing controller 25, the upper end of the support rod 21 is fixedly installed with a light box 22, and warning lights 23 are fixedly installed on both sides of the light box 22, the upper surface of the light box 22 is fixedly installed with an extended mounting rod 24, and the lower surface of the extended mounting rod 24 is fixedly installed with an infrared human body sensing controller 25 near one end, and a DC power supply and a single-chip microcomputer are arranged inside the extended mounting rod 24; the DC power supply is powered by the mains connection, and the DC power supply supplies the converted electrical energy to the single-chip microcomputer and the infrared human body sensing controller 25, wherein the model of the infrared human body sensing controller 25 is LC1620-pir, and the surface of the partition rod 3 and the support rod 21 are both provided with a female spiral pattern 31 near the lower end, and the partition rod 3 is provided with three, and the partition rod 3 and the support rod 21 are both screwed into the sub-spiral pattern 14 at the corresponding position through the female spiral pattern 31 and fixedly installed with the pre-installed seat 1; the protective structure 4 includes a protective cover 41, an insertion hole 42 , locking holes 43, embedding grooves 44 and quick-connect slots 45. The surface of the protective outer cover 41 is provided with an insertion hole 42, an embedding groove 44 is provided in the middle of the lower surface of the protective outer cover 41, and quick-connect slots 45 are provided in front and behind the embedding groove 44 on the lower surface of the protective outer cover 41.

Then, it is only necessary to pass the dividing rod 3 and the support rod 21 through the female spiral 31 through the insertion hole 42 at the corresponding position and tighten it in the sub-spiral 14 to fix it. In this way, the installation is completed. If the dividing rod 3 or the support rod 21 is damaged in the future, it only needs to be unscrewed and disassembled, and if the protective cover 41 is damaged, it only needs to be removed and locked. The screws, support rods 21 and dividing rods 3 in the holes 43 can be removed without damaging the expansion bolts connected to the ground and the ground, which makes disassembly easier. During use, as long as the human body enters the sensing range of the infrared human body sensing controller 25, its sensing signal is transmitted to the single-chip microcomputer through the wire, and the single-chip microcomputer immediately takes action to control the warning light 23 to flash. Therefore, before the pedestrian reaches the central dividing strip, the driver is warned in advance that there are pedestrians crossing the road on the left, which can provide the driver with enough time to slow down and avoid the situation where the driver takes chances and does not slow down, causing traffic accidents.
