[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a road traffic safety education information display device, including a base frame 1, a hinge rod 2, a housing 3, and a cover 4. The hinge rod 2 is symmetrically fixedly connected to both sides of the base frame 1. The top of the hinge rod 2 is hinged to the housing 3 through a rotating shaft 15. A multimedia player is built into the housing 3. A cover 4 is provided on one side of the housing 3. A transparent acrylic plate 13 is fixedly connected to the inside of the cover 4. A connecting mechanism is provided between the housing 3 and the cover 4. An angle adjustment mechanism is provided on one side of the base frame 1. The multimedia player is placed into the housing 3 along the inner wall. Then, the cover 4 is closed on one side of the housing 3. The cover 4 and the housing 3 are connected as one unit by the connecting mechanism. The housing 3 and the cover 4 enclose the multimedia player, preventing external objects from directly contacting the multimedia player and protecting it. Then, the angle adjustment mechanism drives the housing 3, the cover 4, and the multimedia player to rotate from a horizontal state to a vertical state. The multimedia player broadcasts illegal videos to the outside world for safety education.

[0019] The connecting mechanism includes a connecting plate 5, a cam rod 6, an insert block 7, and an arc groove 8. Insert blocks 7 are symmetrically fixedly connected to both sides of the cover 4, and connecting plates 5 are symmetrically fixedly connected to both sides of the housing 3. Cam rods 6 are symmetrically and eccentrically hinged to the top and bottom of the connecting plates 5. Arc grooves 8 are symmetrically provided at the top and bottom of the insert blocks 7. The outer wall of the cam rod 6 fits against the inner wall of the arc groove 8. The cover 4 covers one side of the housing 3. The insert blocks 7 on both sides of the cover 4 are inserted into the middle of the two connecting plates 5. Rotating the two cam rods 6 towards the insert blocks 7 clamps the arc grooves 8 at the top and bottom of the insert blocks 7, thus connecting the connecting plates 5 and the insert blocks 7 as one unit. At this time, the cover 4 and the housing 3 are fixed together, and the housing 3 and the cover 4 enclose the multimedia player, preventing external objects from directly contacting the multimedia player and protecting it. Rotating the two cam rods 6 outwards separates them from the insert blocks 7, allowing the cover 4 to be separated from the housing 3 and the multimedia player to be removed from the inside of the housing 3 for inspection.

[0020] The angle adjustment mechanism includes a cylinder 9, a connecting arm 10, and a hinge seat 14. The hinge seat 14 is symmetrically fixedly connected to one side of the base frame 1. The cylinder 9 is hinged to the top of the hinge seat 14. The output end of the cylinder 9 is fixedly connected to the connecting arm 10. The two sides of the cover 4 are symmetrically fixedly connected to pins. One end of the connecting arm 10 is hinged to one end of the pin. When the output end of the cylinder 9 moves, it can drive the housing 3 to rotate around the top of the hinge rod 2 as the center, which can adjust the housing 3 to a vertical or horizontal state. When the multimedia player is in a vertical state with the housing 3, it is convenient to display to the outside world through the multimedia player. When the multimedia player is in a horizontal state with the housing 3, it reduces the footprint of the housing 3 and the multimedia player, making it convenient to store.

[0021] The hinge rod 2 is composed of a long rod and a short rod. The short rod is welded to one side of the long rod, and the short rod and the long rod form a triangular structure. The long rod and the short rod form the hinge rod 2 and form a triangular structure. The triangular structure is stable, and the hinge rod 2 can stably support the shell 3.

[0022] Both the outer sides of the housing 3 and the cover 4 are provided with rubber sealing strips. A layer of glass glue is applied at the intersection of the cover 4 and the transparent acrylic plate 13. The rubber sealing strips and glass glue can fill the gaps between the housing 3, the cover 4 and the transparent acrylic plate 13 to ensure the airtightness between the housing 3, the cover 4 and the transparent acrylic plate 13, and prevent foreign objects from entering the interior of the housing 3 and causing damage to the multimedia player.

[0023] A rechargeable outdoor power supply box 11 is fixedly installed inside the base frame 1. A round hole matching the power socket of the housing 3 is provided on one side of the bottom of the housing 3. A connecting wire 12 is connected to one side of the rechargeable outdoor power supply box 11. One end of the connecting wire 12 is inserted into the power socket through the round hole. The other end of the connecting wire 12 is connected to a plug. The plug is connected to a socket to charge and store electrical energy for the rechargeable outdoor power supply box 11. The rechargeable outdoor power supply box 11 has an indicator light to show the power level. After the power is fully charged, the plug is unplugged and separated from the connecting wire 12. The device is transported to the intersection where traffic police officers are on duty. After the housing 3 is turned over, one end of the connecting wire 12 is inserted into the power socket through the round hole. The rechargeable outdoor power supply box 11 provides power to the multimedia player through the connecting wire 12 and starts working. The traffic police officers transmit traffic accident videos to the multimedia player through the cloud and broadcast the illegal videos to the outside world for safety education.

[0024] The connecting line 12 is wrapped with a protective sleeve made of rubber material. The rubber material contains a metal wire. The rubber protective sleeve wraps around the connecting line 12, and the metal wire can increase the toughness and strength of the protective sleeve, thus providing better protection for the connecting line 12.

[0025] The road traffic safety education information display device has a cover 4 that covers one side of the housing 3. The inserts 7 on both sides of the cover 4 are inserted into the middle of the two connecting plates 5. Rotating the two cam rods 6 towards the inserts 7 clamps the arc-shaped grooves 8 at the top and bottom of the inserts 7, thus connecting the connecting plates 5 and the inserts 7 into one unit. At this time, the cover 4 and the housing 3 are fixed to each other, and the housing 3 and the cover 4 enclose the multimedia player, preventing external objects from directly contacting the multimedia player and protecting it. Rotating the two cam rods 6 outwards separates them from the inserts 7, allowing the cover 4 to be separated from the housing 3 and the multimedia player to be removed from the inside of the housing 3 for inspection and maintenance.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
