Description

Technical Field

[0001] This utility model relates to the field of forestry protection technology, specifically a forestry protection and fire prevention publicity and display device. Background Technology

[0002] Fire is the greatest threat to forests. Forest fires can burn large areas of forest, harm a large number of animals, reduce the regeneration capacity of forests, damage the forest's function of conserving water sources, and expose the ground, making it easy to trigger secondary disasters such as landslides and mudslides. Therefore, fire prevention is the key to forestry safety protection and construction. In particular, forestry fire prevention publicity work can raise people's awareness of fire prevention and prevent problems before they occur.

[0003] The existing forestry protection and fire prevention publicity and display devices have fixed structures for their bulletin boards, which cannot be adjusted and are therefore unsuitable for posters of various lengths. Utility Model Content

[0004] The purpose of this utility model is to provide a forestry protection and fire prevention publicity and display device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a forestry protection and fire prevention publicity and display device, comprising a base plate, multiple support frames fixedly connected to the corner of the top surface of the base plate, mounting blocks slidably arranged inside the support frames, two mounting grooves opened on the left and right sides of the mounting blocks, a first limiting component arranged inside the mounting grooves, casters fixedly connected to the bottom surface of the mounting blocks, two support rods fixedly connected to both ends of the top surface of the base plate, mounting frames fixedly connected to the top surfaces of the two support rods, two display panels slidably arranged inside the mounting frames, two fixed brackets symmetrically distributed and fixedly connected to the top of the rear side of the mounting frames, an adjustment component arranged in the middle of the fixed brackets, and a second limiting component arranged at the rear end of the fixed brackets.

[0006] Preferably, the first limiting component includes a mounting plate, a spring, and a limiting rod. The mounting plate is snapped into the inner side of the mounting groove, the spring is fixedly connected to the side of the mounting plate, and the limiting rod is fixedly connected to the end of the spring away from the mounting plate.

[0007] Preferably, the adjustment assembly includes a rotating rod, a rotating plate, a gear, and a rack. The rotating rod is rotatably connected to the middle of the fixed bracket, the rotating plate is fixedly connected to the top surface of the rotating rod, the gear is fixedly connected to the bottom end of the rotating rod, and the rack is fixedly connected to the upper end of the rear side of the display panel. The rack is meshed with the gear.

[0008] Preferably, the second limiting component includes a fixed base and a limiting ring. The fixed base is fixedly connected to the rear end of the top surface of the fixed bracket, and one end of the limiting ring is hinged to the inner side of the fixed base. The inner side of the limiting ring is provided with multiple limiting grooves distributed in a circular pattern.

[0009] Preferably, a connecting rod is fixedly connected to the top surface of the mounting block, and the top end of the connecting rod passes through the support frame and is fixedly connected to a trapezoidal block.

[0010] Preferably, the mounting bracket has two sliding grooves on its upper and lower sides, and the display board has two sliders fixedly connected to its upper and lower sides, with the sliders slidably disposed inside the sliding grooves.

[0011] Preferably, the support frame has multiple limiting holes distributed vertically on its left and right sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When in use, the universal wheels make the whole device easy to move. Press the limiting rod into the mounting groove, and the trapezoidal block drives the connecting rod and mounting block to move upward until the mounting groove coincides with the limiting hole located above. Under the action of the spring, the limiting rod pops out into the limiting hole, so that the universal wheels are hidden in the support frame and the bottom plate contacts the ground, which improves the stability when placed.

[0014] 2. When using this utility model, rotating the rotating plate causes the rotating rod to drive the gear to rotate. Since the gear and rack mesh, the rack drives the display plate to move outward from the mounting frame, thereby adjusting the distance between the two display plates, which is convenient for installing posters of different lengths. The limiting ring is placed on the rotating plate, and the corner of the rotating plate is locked in the limiting groove, thereby limiting the adjustment component. Attached Figure Description
