Description

Technical Field

[0001] This utility model relates to the field of signage technology, and in particular to a confined space warning sign. Background Technology

[0002] In industrial production, municipal engineering, and other fields, confined space operations involve risks such as oxygen deficiency, accumulation of toxic and harmful gases, and flammability and explosiveness. Therefore, it is essential to clearly indicate these hazards using warning signs. Confined space warning signs are a crucial component of on-site safety protection, effectively reminding workers to avoid risks and ensuring their safety.

[0003] Currently, traditional confined space warning signs mostly adopt fixed installation and integrated structures. Their mechanical design mainly relies on bolt fixing to the foundation or hanging brackets, and the protective structure is usually just a single flat back panel or a simple shell. The graphic information on the surface of the sign is mostly presented in the form of ink printing or film, and is fixed to the back panel by adhesive or mechanical riveting.

[0004] However, in practical applications, signs are exposed to complex environments such as humidity, dust, and corrosive gases for extended periods, which can easily lead to blurred graphics and deformed backings due to corrosion, thus affecting the readability and effectiveness of warning information. For example, in chemical industrial parks and underground sewage networks, signs often suffer from peeling reflective film and fading text due to corrosion from acid and alkaline gases or water vapor penetration, rendering them unable to provide timely safety warnings and posing serious safety hazards. Therefore, a confined space warning sign is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a confined space warning sign, which aims to improve the problem that existing signs exposed to complex environments such as humidity, dust, and corrosive gases for a long time are prone to erosion, resulting in blurred graphics and deformed backing, which in turn affects the readability and effectiveness of warning information.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A confined space warning sign includes a sign body, an information panel is provided on the side wall of the sign body, a protective component is provided on the side wall of the sign body, and a fixing component is provided on the lower surface of the information panel; The protective assembly includes a first protective shell and a second protective shell. The side wall of the sign body is slidably connected between the first and second protective shells. One side wall of the first protective shell is rotatably connected to the side wall of the second protective shell. A first hook is fixedly connected inside the second protective shell. A second hook is slidably connected inside the first protective shell. A pressing block is slidably connected inside the first protective shell. The side wall of the pressing block is fixedly connected to the side wall of the second hook. A fixing seat is fixedly connected inside the first protective shell. A spring is provided inside the first protective shell. One end of the spring is fixedly connected to the side wall of the fixing seat, and the other end of the spring is fixedly connected to the side wall of the second hook.

[0007] As a further description of the above technical solution: The fixing component includes a positioning block, the sidewall of which is fixedly connected to the lower surface of the information board, and the sidewall of which is slidably connected inside the sign body.

[0008] As a further description of the above technical solution: The first hook and the second hook engage with each other, and the side wall of the second hook is slidably connected inside the second protective shell.

[0009] As a further description of the above technical solution: A rotating shaft is fixedly connected inside the protective shell. The two side walls of the protective shell are rotatably connected to the side wall of the rotating shaft. A torsion spring is sleeved on the side wall of the rotating shaft. One end of the torsion spring is attached to one side wall of the protective shell, and the other end of the torsion spring is attached to the two side walls of the protective shell.

[0010] As a further description of the above technical solution: The sign body has a positioning groove inside, and the side wall of the positioning block is slidably connected inside the positioning groove.

[0011] As a further description of the above technical solution: The sign body has a magnetic block 1 inside, and the information sign has a magnetic block 2 on its lower surface. The magnetic block 1 and the magnetic block 2 attract each other.

[0012] As a further description of the above technical solution: The magnetic blocks are symmetrically distributed around the information board and correspond to the magnetic blocks. The positioning blocks are symmetrically distributed at the four corners of the information board and correspond to the positioning slots.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the sign body is protected from external environmental corrosion by protective shell one and protective shell two. By pressing the squeezing block, the second hook squeezes the spring, causing the second hook to separate from the first hook, thus releasing the lock on the second protective shell. At this time, the second protective shell can be rotated to open the protective assembly, exposing the sign body for easy installation and removal. This solves the problem that some warning signs in confined spaces are exposed to complex environments such as moisture, dust, and corrosive gases for a long time, which are prone to corrosion, resulting in blurred graphics and deformed back panels, thus affecting the readability and effectiveness of warning information. The above structure improves the protective effect on the sign. 2. In this utility model, when installing the information sign, the positioning block on the lower surface of the information sign is aligned with the positioning groove inside the sign body. During the insertion process, the positioning block slides along the positioning groove. When the information sign is fully inserted, the magnetic block two on the lower surface of the information sign and the magnetic block one inside the sign body attract each other, further fixing the information sign with magnetic force to prevent it from loosening or falling off. When replacing the information sign, simply overcome the magnetic force of the magnetic block one and the magnetic block two, pull the information sign upwards, and let the positioning block disengage from the positioning groove. Then the information sign can be removed and a new information sign can be installed. Attached Figure Description

[0016] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a confined space warning sign, including a sign body 1, which carries warning information for confined spaces and serves to remind workers of potential dangers. An information board 2 is provided on the side wall of the sign body 1, which displays detailed information such as safety tips and emergency measures, enabling flexible information replacement and updating. A protective component is provided on the side wall of the sign body 1 to protect the sign body 1 and the information board 2, preventing external environmental corrosion and extending service life. A fixing component is provided on the lower surface of the information board 2 to securely connect the information board 2 to the sign body 1, facilitating easy installation and removal of the information board 2. The protective components include a first protective shell 3 and a second protective shell 4. The first and second protective shells 3 and 4 enclose the sign body 1, effectively isolating it from external environmental factors such as moisture, dust, and corrosive gases, thus protecting the internal structure. The side wall of the sign body 1 is slidably connected between the first and second protective shells 3 and 4, allowing the sign body 1 to be stably placed inside the protective shells and facilitating installation and removal. The side wall of the first protective shell 3 is rotatably connected to the side wall of the second protective shell 4. A hook 7 is fixedly connected inside the second protective shell 4, and a hook 8 is slidably connected inside the first protective shell 3. A pressing block 9 is slidably connected inside the first protective shell 3, and its side wall is fixedly connected to the side wall of the hook 8. The pressing block 9 cooperates with the hook 8 to slide horizontally. Pressing the pressing block 9 moves the hook 8, releasing the locking state of the hooks 7 and 8. A fixing seat 10 is fixedly connected inside the first protective shell 3, and a spring 11 is installed inside the first protective shell 3. One end of spring 11 is fixedly connected to the side wall of the fixed base 10, and the other end of spring 11 is fixedly connected to the side wall of hook 2 8. Spring 11 is used to provide a reset force after hook 2 8 moves, so as to realize the effect of hook 2 8 automatically rebounding and resetting, and to facilitate locking with hook 1 7 again. Hook 1 7 and hook 2 8 are engaged. The side wall of hook 2 8 is slidably connected to the inside of protective shell 2 4. The two work together to achieve the effect of tightly locking protective shell 1 3 and protective shell 2 4, ensuring the sealing of the protective component. A rotating shaft 5 is fixedly connected inside protective shell 1 3. The rotating shaft 5 serves to provide the axis for the rotation of protective shell 1 3 and protective shell 2 4. The side wall of protective shell 2 4 is rotatably connected to the side wall of rotating shaft 5. A torsion spring 6 is sleeved on the side wall of rotating shaft 5. One end of torsion spring 6 is attached to the side wall of protective shell 1 3, and the other end of torsion spring 6 is attached to the side wall of protective shell 2 4. The torsion spring 6 is made of elastic metal wire, so as to keep protective shell 1 3 and protective shell 2 4 in a closed state when no external force is applied. Reference Figures 4-5The fixing component includes a positioning block 15, which defines the installation position of the information sign 2 on the sign body 1, achieving precise positioning and preventing the information sign 2 from shifting. The side wall of the positioning block 15 is fixedly connected to the lower surface of the information sign 2 and slidably connected inside the sign body 1, achieving initial connection and guidance between the information sign 2 and the sign body 1. The sign body 1 has a positioning groove 12 inside, which cooperates with the positioning block 15, and the two slide and embed, achieving the effect of quickly installing the information sign 2 to the designated position. The side wall of the positioning block 15 is slidably connected inside the positioning groove 12, ensuring that the information sign 2 remains stable after installation and does not shake. A magnetic block 13 is provided inside the sign body 1, and a magnetic block 24 is provided on the lower surface of the information sign 2. The magnetic blocks 13 and 24 further reinforce the connection between the information sign 2 and the sign body 1, preventing the information sign 2 from shifting. When signboard 2 detaches, magnetic block 13 and magnetic block 2 14 attract each other, working together to achieve tool-free quick installation and removal of signboard 2, improving maintenance efficiency. Magnetic block 2 14 is symmetrically distributed around signboard 2 and corresponds to magnetic block 13. This symmetrical distribution ensures that the magnetic force is evenly applied to signboard 2, achieving a stable and balanced fixation of signboard 2. Positioning blocks 15 are symmetrically distributed at the four corners of signboard 2 and correspond to positioning grooves 12. Positioning blocks 15 and positioning grooves 12 work together to achieve precise alignment during installation of signboard 2, avoiding the influence of installation deviation on the attraction effect of magnetic block 13 and magnetic block 2 14. The combination of positioning blocks 15 and magnetic block 2 14, with positioning blocks 15 first defining the position and magnetic block 2 14 then providing the fastening force, achieves the dual effect of ensuring both installation accuracy and a firm connection, allowing signboard 2 to be stably installed on signboard body 1 and facilitating quick replacement later.

[0018] Working principle: When using this sign, the protective shell 3 is pre-installed in the required position, and then the sign body 1 is placed inside to achieve the warning function. When it is necessary to view or change the information, press the squeezing block 9. The squeezing block 9 drives the hook 2 8 to compress the spring 11 and slide into the protective shell 3. The hook 2 8 separates from the hook 1 7, releasing the lock on the protective shell 2 4. At this time, the protective shell 2 4 can be rotated to open the protective assembly and expose the sign body 1. When closing the protective shell, turn the protective shell 2 4 back to its original position. The hook 2 8 extends under the reset action of the spring 11 and re-engages with the hook 1 7, completing the closure of the protective shell and protecting the sign body 1 from the external environment. To prevent environmental erosion, when it is necessary to install information sign 2, align the positioning block 15 on the lower surface of information sign 2 with the positioning groove 12 inside the sign body 1. During insertion, the positioning block 15 slides along the positioning groove 12, which plays a role in positioning and initial fixation. When information sign 2 is fully inserted, the magnetic block 14 on the lower surface of information sign 2 and the magnetic block 13 inside the sign body 1 attract each other, and further fix information sign 2 by magnetic force to prevent it from loosening or falling off. When replacing information sign 2, simply overcome the magnetic force of magnetic block 13 and magnetic block 14, pull information sign 2 upward, so that positioning block 15 is disengaged from positioning groove 12, and information sign 2 can be removed and a new information sign 2 can be installed.
