Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and in particular to a construction safety education and training equipment. Background Technology

[0002] In the construction industry, safety education and training are crucial for ensuring the safety of construction workers and reducing accidents. Currently, safety education and training on construction sites often involve playing safety education videos on floor-standing televisions. While these televisions can visually present accident cases and standardized operating procedures, they have significant limitations in functionality.

[0003] From the perspective of actual training needs, during post-training explanations, personnel not only need to rely on videos to demonstrate basic content, but also need to write down and annotate key knowledge points (such as safety points under special working conditions, detailed equipment operation specifications, etc.) and conduct on-site demonstrations to enhance workers' understanding and memory. However, existing floor-standing televisions only have a single function of video playback. To meet the writing needs, an additional independent writing board needs to be installed next to it. However, the additional writing board increases the space occupied, further compressing the space for personnel activities and equipment placement in an already compact construction site or training room, resulting in a cluttered training environment. Therefore, we propose a construction safety education and training device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing floor-standing televisions, which only have a single function of video playback and require an additional independent writing board to meet writing needs. This invention provides a construction safety education and training device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A construction safety education and training device includes a floor frame, a mounting frame on the top of the floor frame, two interlocking whiteboards mounted on the upper and lower ends of the mounting frame via a sliding and rotating structure, and a display screen fixed on the front surface of the mounting frame. When the whiteboard is moved to the front of the display screen, it covers the surface of the display screen.

[0006] Preferably, the sliding and rotating structure includes a slide groove formed on the mounting frame, a slide seat provided in the slide groove, a spring provided between the slide seat and the outer end wall of the slide groove, and a connecting rod provided between the slide seat and the writing whiteboard. The two ends of the connecting rod are rotatably connected to the top of the slide seat and the top of the writing whiteboard, respectively. By pulling the writing whiteboard to both sides, the slide seat is driven to slide outward in the slide groove. When pulled a certain distance, the writing whiteboard can be rotated to the rear of the display screen, thereby exposing the display screen for video training.

[0007] Preferably, a guide post is fixed between the inner walls of both ends of the slide groove, and both the slide block and the spring are sleeved on the guide post. The guide post improves the stability when the spring is compressed and the slide block moves.

[0008] Preferably, when the two whiteboards are spliced ​​together, the spring is compressed and there is a gap between the slide and the inner wall of the slide groove. This arrangement allows the whiteboard to be attached to the surface of the display screen by the spring, reducing the entry of dust.

[0009] Preferably, guide wheels are provided on the upper and lower outer walls of the mounting bracket, and the guide wheels make rolling contact with the whiteboard, which facilitates the whiteboard to rotate around the side of the display screen.

[0010] Preferably, the back of the writing whiteboard is detachably connected to a dustproof layer, which is one of cotton cloth, sponge, or rubber.

[0011] Preferably, the dustproof layer is connected to the whiteboard via Velcro or snaps, making it easy to remove and clean after prolonged use.

[0012] Preferably, both whiteboards are provided with handles on their outer sides, and the sides of the two whiteboards that are close to each other are provided with matching connecting protrusions and connecting grooves, so as to splice the two whiteboards together and expand the writing area.

[0013] Preferably, the lower end of the display screen is provided with a placement tray, which is fixed on the floor frame and is used to place training aids such as writing pens and erasers.

[0014] The beneficial effects of this utility model are as follows: Compared with existing technologies, this utility model integrates video playback and writing functions by setting up a floor stand, mounting frame, writing whiteboard, display screen, and sliding and rotating structures. Pulling and rotating the writing whiteboard can expose the display screen to play videos, and it can be used for writing after being reset. It does not require an additional writing board, thus saving space. At the same time, the dustproof layer structure on the back of the writing whiteboard can prevent dust from entering the display screen when the device is not in use, avoiding the situation where the display screen becomes unclear due to excessive dust on the surface after a long period of time.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Reference Figure 1-5 A construction safety education and training device includes a floor frame 1, which is made of metal, preferably stainless steel or alloy steel, and has high strength and rust resistance. The bottom of the floor frame 1 is equipped with an anti-slip pad, which is made of rubber and has anti-slip texture on the surface to increase the friction with the placement surface, improve the overall stability of the device, and prevent tipping. The top of the floor stand 1 is equipped with a mounting bracket 2, and a display screen 3 is fixed on the front surface of the mounting bracket 2. The display screen 3 is electrically connected to an external control terminal and can receive and play video signals through wired (such as HDMI, VGA, etc.) or wireless (such as Bluetooth, etc.) methods. It supports the playback of various content such as construction safety education videos and teaching courseware, and meets the needs of training video display. When the whiteboard 4 moves to the front of the display screen 3, the whiteboard 4 covers the surface of the display screen 3.

[0019] Slide grooves 21 are provided on both the upper and lower ends of the mounting bracket 2. The slide grooves 21 are long strip-shaped through grooves that extend along the length of the mounting bracket 2. Their inner walls are polished to reduce frictional resistance. A guide post 22 is provided inside the slide groove 21. The guide post 22 is cylindrical and parallel to the length direction of the slide groove 21. A slide block 23 is fitted on the guide post 22. A wear-resistant bushing is provided on the inner wall of the slide block 23 to ensure smooth sliding. A spring 24 is provided between the slide block 23 and the outer end wall of the slide groove 21. The spring 24 is sleeved on the guide post 22. The setting of the guide post 22 improves the stability of the spring 24 when it is compressed and the slide block 23 moves. At the same time, it provides elastic force for the whiteboard 4 to be reset. The slide block 23 and the whiteboard 4 are rotatably connected by a connecting rod 5. The two ends of the connecting rod 5 are rotatably connected to the top of the slide block 23 and the top of the whiteboard 4, respectively. By pulling the whiteboard 4 to both sides, the slide block 23 is driven to slide outward in the slide groove 21. When it is pulled a certain distance, the whiteboard 4 can be rotated so that the whiteboard 4 is rotated to the rear of the display screen 3, thereby exposing the display screen 3 for video training.

[0020] Among them, guide wheels 25 are provided on the upper and lower outer walls of the mounting bracket 2. The guide wheels 25 are made of rubber and have a smooth surface. The guide wheels 25 roll in contact with the writing whiteboard 4, making it easy for the writing whiteboard 4 to rotate around the side of the display screen 3. The writing whiteboard 4 is made of high-strength composite board, which has good writing smoothness and abrasion resistance. Both writing whiteboards 4 are equipped with handles 42 on their outer sides. The handles 42 make it easy to pull the writing whiteboard 4 to move. The two writing whiteboards 4 are respectively equipped with a connecting protrusion 43 and a connecting groove 44 on the side of the two writing whiteboards 4 that are close to each other, so as to realize the splicing of the two writing whiteboards 4 and expand the writing area. The back of the whiteboard 4 is connected to a cotton cloth via Velcro or snaps. When the whiteboard 4 covers the surface of the display screen 3, the cotton cloth prevents dust from entering. The cotton cloth can also be removed for cleaning after prolonged use. In addition to cotton cloth, materials with protective effects such as sponge or rubber can also be used.

[0021] It should be noted that when the two whiteboards 4 are spliced ​​together, the spring 24 is in a compressed state, and there is a gap between the slide 23 and the inner end wall of the slide groove 21. This setting allows the whiteboard 4 to be attached to the surface of the display screen 3 by the spring 24, reducing the entry of dust.

[0022] Furthermore, a placement tray 6 is provided at the lower end of the display screen 3. The placement tray 6 is fixed on the floor frame 1. The placement tray 6 is used to place training auxiliary tools such as writing pens and erasers. The surface of the placement tray 6 is provided with anti-slip texture to prevent the placed writing tools and other items from slipping, ensuring that the tools are easy to access and stable.

[0023] In this embodiment, when video training is required, the writing whiteboards 4 on both sides are pulled, causing the slide base 23 to slide outward. When pulled a certain distance, the writing whiteboard 4 can rotate around the guide wheel 25, so that the writing whiteboard 4 rotates to the rear of the display screen 3, thereby exposing the display screen 3 for video training.

[0024] When writing is required, the writing whiteboard 4 on the back is pulled again to rotate to the front, and the two writing whiteboards 4 are spliced ​​together. The spring 24 drives the writing whiteboard 4 to cover the surface of the display screen 3. The display screen 3 is protected from dust by the dustproof layer 41. At the same time, writing can be done on the writing whiteboard 4. The device integrates video playback and writing functions, eliminating the need for an additional writing board and saving space.
