Description

Technical Field

[0001] The utility model relates to the technical field of construction site information public notice boards, in particular to a construction site information public notice board. Background Art

[0002] A project needs to set up public notice boards at the entrance and exit of the construction site. The notice boards will publish information such as environmental protection requirements around the construction site, the impact of construction on the surrounding environment, and related environmental protection measures, so that the public can understand it in a timely manner and take corresponding response measures.

[0003] Existing construction site information notice boards usually use LED screens for display, and the display content is limited. In addition, the LED screen takes up a lot of space. When personnel view the construction site information, they need to look up from the LED screen, which is troublesome. In addition, in extreme weather, the existing construction site information notice boards are difficult to retract and are prone to damage. Therefore, we propose a construction site information notice board. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a construction site information notice board, which can display more detailed information through a liquid crystal display screen and is more suitable for close viewing.

The upper ends of the two support frames are fixedly connected to installation boxes, and the rear wall of the installation box is fixedly connected to a display screen, which is a liquid crystal display screen. The input end of the display screen is electrically connected to the output end of the integrated terminal;

[0007] Support mechanism: It is respectively arranged on the left and right sides of the hollow base. It can display more details through the LCD screen and is more suitable for close viewing. It is also a movable notice board, which can extend the service life of the display screen.

[0008] Furthermore, the supporting mechanism includes a connecting rod, a support rod and a rotating seat. The rotating seats are symmetrically arranged at the four corners of the upper surface of the hollow base. The opposite side surfaces of the two rotating seats on the left and right sides are rotatably connected with support rods through a pin shaft. The upper ends of the two support rods on the left and right sides are fixedly connected with a connecting rod to support the hollow base.

[0009] Furthermore, the supporting mechanism also includes a top rod, a bracket and a connecting rod three. Brackets are provided on both sides of the left and right sides of the interior of the hollow base. The upper ends of the opposite sides of the two supporting rods on the same side are rotatably connected to the top rod through a second pin. A connecting rod three is fixedly connected between the two top rods on the same side. The lower ends of the two top rods on the same side are respectively clamped in the inside of the card grooves formed inside the adjacent brackets and the hollow base to achieve self-locking of the support rods.

[0010] Furthermore, the support mechanism also includes a tilting rod and a connecting rod 2. The front and rear ends of the bracket are rotatably connected to the tilting rod through a pin shaft 3. The outer arc surface of the tilting rod is in contact with the lower end of the adjacent connecting rod 3. The connecting rod 2 is fixedly connected between the two tilting rods on the left and right sides. The connecting rod 2 is respectively located at one end of the tilting rods on the left and right sides away from the adjacent bracket, so as to facilitate the retraction of the support rod.

[0011] Furthermore, a limit plate is provided on the edge of the front side of the installation box, and a protective cover is clamped on the outer side of the limit plate. The protective cover is a transparent plastic protective cover. The display screen is located inside the protective cover. The edge of the protective cover is connected to the front side of the installation box by bolts to isolate dust.

[0012] Furthermore, a sunshade is provided at the upper end of the installation box to facilitate personnel to view the display screen.

[0013] Furthermore, the bottom wall of the installation box is provided with evenly distributed heat dissipation holes to facilitate heat dissipation inside the installation box.

[0014] Compared with the prior art, the beneficial effects of the utility model are: the construction site information notice board has the following advantages:

[0015] 1. The project management personnel push the site information notice board to the door of the construction site with casters. After power is turned on, the information of the project is transmitted to the display screen through the integrated terminal for display. The protective cover isolates dust to prevent dust from sticking to the surface of the display screen. The sun visor blocks the sunlight to facilitate personnel to watch the display screen.

[0016] 2. Pull the connecting rod one to the middle part of the hollow base respectively, and the connecting rod one drives the supporting rod on the same side to rotate on the adjacent rotating seat, and the supporting rod contacts the ground to support the hollow base, and at the same time, the top rod is pulled by the supporting rod to the adjacent bracket and the inner groove formed in the hollow base, and the lower end of the top rod falls into and is clamped in the inner groove formed in the adjacent bracket and the hollow base respectively. Under the action of the gravity of the installation box, the lower end of the supporting rod slides toward the middle part of the hollow base, and the upper end of the supporting rod pushes the lower end of the adjacent top rod to press against the adjacent inner wall of the hollow base. At this time, the top rod and the adjacent supporting rods and the hollow base form a triangular structure, the casters are off the ground, and the lower end of the support rod stably supports the hollow base to prevent the information display board of this construction site from sliding. In case of strong wind and heavy rain, step on the connecting rod two, and the lifting rod pushes the connecting rod three. The lower end of the top rod leaves the inner groove formed in the adjacent bracket and the hollow base. The retraction of the support rod no longer supports the hollow base, and the casters contact the ground. Then push the construction site information notice board into the house where it will not be affected by strong winds and heavy rain to prevent the display screen from getting wet and causing problems such as short circuits.
