Description

Technical Field

[0001] This invention relates to the field of signage technology, specifically to a safety production signage based on magnetic attraction, adhesive, and negative pressure synergistic fixation and its installation method. Background Technology

[0002] In industrial production settings, safety signs are indispensable tools for conveying safety regulations and warning of operational risks. They need to be stably and smoothly attached to the casings of various production equipment over a long period. These equipment casings are mostly made of magnetically compatible materials such as iron or stainless steel, and the working environment often involves complex factors such as continuous vibration, oil contamination, and temperature fluctuations. Currently, the commonly used methods for fixing safety signs have significant limitations: First, widely used pure adhesive bonding methods, such as ordinary double-sided tape, are prone to fatigue and aging of the adhesive layer under long-term and severe equipment vibration, leading to adhesive failure and causing the signs to curl up or even fall off completely. In addition, during the manual bonding process, air is very likely to remain between the sign and the equipment surface, forming air bubbles that are difficult to eliminate. This not only makes the surface of the sign uneven, but also causes the key safety warning information to be distorted and blurred, seriously weakening its safety reminder function.

[0003] Secondly, while simple magnetic fixing solutions are convenient to install, they are prone to displacement under vibration, lack stability, and cannot be applied to non-ferromagnetic surfaces. Although some improved solutions combining magnetism and adhesive have been developed, they have not effectively solved the problem of localized lifting caused by material deformation or adhesive layer creep during long-term use.

[0004] The aforementioned defects collectively result in the short lifespan and high maintenance costs of existing signs, failing to meet the core requirements of "long-term stability, clear visibility, and convenient installation" in industrial applications, thus constituting a long-standing and urgent technical problem that needs to be solved. Summary of the Invention

[0005] This invention aims to solve the technical problems of existing signs, such as warping, detachment, and instability under vibration due to the single fixing method. To address these problems, this invention provides the following technical solution: A safety production sign includes: The sign body includes a logo portion in the center of the front and stretchable portions on its sides, and the logo portion and / or stretchable portions are made of magnetic material; A U-shaped base is fixedly connected to the back edge of the card body. An adhesive layer for bonding with the outer shell of the production equipment is provided on the side of the U-shaped base away from the card body. Wedge-shaped grooves are provided on two opposite side walls of the U-shaped base. A magnetic piston rod is disposed between the U-shaped seats. The two ends of the magnetic piston rod are symmetrically provided with wedge-shaped portions that are adapted to the wedge-shaped grooves. The wedge-shaped portions are engaged in the wedge-shaped grooves and can slide along them. A pull rope is attached to the side wall of the magnetic piston rod; The sign body, the U-shaped base, the magnetic piston rod, and the production equipment shell opposite to the sign body together form a closed space. By pulling the rope, the magnetic piston rod is driven to move along the wedge-shaped groove toward the opening end of the U-shaped base, reducing the pressure in the closed space and causing the sign part to fit tightly against the production equipment shell under atmospheric pressure.

[0006] Furthermore, the magnetic piston rod forms a double-sided magnetic coupling with the flexible magnetic plate body and the iron production equipment shell, which is used to prevent the magnetic piston rod from moving back after it moves.

[0007] Furthermore, the side of the magnetic piston rod away from the card body is coplanar with the side of the adhesive layer away from the U-shaped seat.

[0008] Furthermore, a sealing gasket is provided on the side of the magnetic piston rod away from the card body, and the side of the sealing gasket away from the magnetic piston rod is coplanar with the side of the adhesive layer away from the U-shaped seat.

[0009] Furthermore, the sealing gasket is made of fluororubber, and the lower surface of the sealing gasket is provided with a micron-level anti-slip texture with a depth of 0.02mm to 0.05mm.

[0010] Furthermore, the surface of the wedge-shaped portion of the magnetic piston rod is covered with a rubber sealing layer.

[0011] Furthermore, the pull cord is made of nylon, and the length of the pull cord is greater than the length of the U-shaped seat.

[0012] Furthermore, the adhesive layer at the lower end of the U-shaped seat is an acrylic pressure-sensitive adhesive with a thickness of 0.1mm to 0.2mm.

[0013] The present invention also provides a method for installing the above-mentioned safety production sign, comprising the following steps: S1. Align and fix the U-shaped seat to the back edge of the card body; S2. Insert the wedge-shaped parts at both ends of the magnetic piston rod into the wedge-shaped groove of the U-shaped seat from the opening of the U-shaped seat, slide the magnetic piston rod along the wedge-shaped groove to a position close to the bottom of the U-shaped seat, and comb the free end of the pull rope to the outside of the U-shaped seat; S3. Secure the U-shaped seat to the predetermined position on the outer shell of the production equipment using the adhesive layer on its lower side, and press the edges evenly to bond them together. Ensure stable bonding at the bonding point; S4. Pull the rope connected to the side wall of the magnetic piston rod to drive the magnetic piston rod along the wedge-shaped groove towards the U. The open end of the base slides to reduce the pressure in the enclosed space formed by the plate body, the U-shaped base, the magnetic piston rod, and the outer shell of the production equipment, so that the marking part of the plate body fits tightly against the outer shell of the production equipment under atmospheric pressure.

[0014] Furthermore, in step S4, the magnetic piston rod is prevented from moving back after it has moved by the magnetic attraction between the magnetic piston rod and the card body and the outer shell of the production equipment.

[0015] Compared with existing technologies, the core advantage of this invention lies in constructing a triple synergistic fixing mechanism of "adhesive initial fixation, magnetic assisted positioning, and negative pressure tight bonding." These three elements are not simply superimposed but rather produce a synergistic effect. Specifically, the adhesive layer under the U-shaped base provides a stable and reliable installation reference frame and a basic sealed environment; the magnetic attraction between the sign and the equipment shell achieves initial adsorption and, together with the magnetic piston rod, forms a guarantee to prevent component backflow; while the sliding piston rod actively reduces the pressure in the enclosed space and cleans the back of the sign during the sliding process, and uses uniform atmospheric pressure to tightly press the sign onto the equipment surface.

[0016] This not only solves the problem of localized warping in traditional pasting methods, ensuring a flat sign surface and clear information visibility, but also greatly improves the long-term stability of the sign in vibration environments, effectively preventing warping and detachment, thereby extending its service life.

[0020] To make the technical means, objectives, and effects achieved by this invention readily understandable, the specific embodiments of this invention will be described in detail below with reference to the accompanying drawings. It should be noted that the scope of protection of this invention is not limited to the specific embodiments described below. Any equivalent substitutions or improvements made by those skilled in the art based on the basic concept of this invention should fall within the scope of protection of this invention.

[0021] Example 1: This embodiment provides a safety production sign, such as Figure 1 As shown, the core component of this sign includes the sign body 1, which is made of flexible magnetic material. This flexible magnet is not a traditional rigid magnet; it is typically made by vulcanizing a mixture of magnetic powders such as neodymium iron boron and strontium ferrite with polymers such as silicone rubber and PVC, thus possessing flexibility and stretchability. The sign body 1 is further divided into two functional areas: a label section 11 located in the center of the front, used for printing or pasting safety warning graphics; and a stretchable section 12 surrounding the label section 11. This stretchable section 12 utilizes the flexibility of its material to elastically deform under stress, allowing the central label section 11 to be pressed against the equipment surface.

[0022] Furthermore, by designing a stepped mold depth, a thickness difference can be formed between the marking part 11 and the stretching part 12 during the one-piece molding process of the sign body 1. That is, the thickness of the marking part 11 is increased relative to the stretching part 12, thereby reducing its deformation capacity and preventing the marking part 11 from being subjected to excessive tensile deformation during the movement of the magnetic piston rod 3, which would affect the movement of the magnetic piston rod 3.

[0023] Please see Figure 2 , it is Figure 1 The diagram shows the back structure of the sign. From the back, a U-shaped base 2 is clearly visible, fixedly connected to the back edge of the sign body 1. The U-shaped base 2 acts as a rigid support frame, and on its side away from the sign body 1, i.e., its lower side, is an adhesive layer for bonding to the outer casing of the production equipment. This adhesive layer is preferably an acrylic pressure-sensitive adhesive, and its thickness can be selected from different specifications, such as 0.1mm, 0.15mm, or 0.2mm, to balance adhesive strength and ease of construction. During transportation and storage, the lower surface of this adhesive layer is covered with a release film to maintain its adhesion. Specifically, wedge-shaped grooves 21 are formed on two opposite sidewalls of the U-shaped base 2. Figure 3 A schematic diagram of the disassembled structure of the sign is shown, providing a clearer view of the relationships between the components. A magnetic piston rod 3 is positioned between the U-shaped seats 2. Both ends of the magnetic piston rod 3 are symmetrically machined with wedge-shaped portions 31 that fit into the wedge-shaped grooves 21 on the U-shaped seats 2. During assembly, the wedge-shaped portions 31 precisely engage within the wedge-shaped grooves 21 and slide along their guide. This wedge-shaped fit not only provides a smooth sliding trajectory but also effectively limits unintended movement of the magnetic piston rod 3 in the vertical and lateral directions, ensuring motion stability. A pull rope 4 is connected to the side wall of the magnetic piston rod 3. This pull rope 4 is preferably made of high-strength nylon, and its length is designed to be greater than the overall length of the U-shaped seats 2 to facilitate the operator's application of force.

[0024] A key design element is that when the sign is initially placed on the outer casing of the production equipment, the back of the sign 1, the U-shaped base 2, the magnetic piston rod 3, and the outer casing of the production equipment opposite the sign 1 together form an initial enclosed space. Please refer to... Figure 4 The view shows the state after the sign is connected to the production equipment casing. By pulling the pull rope 4, the magnetic piston rod 3 can be moved along the wedge groove 21 towards the opening end of the U-shaped seat 2.

[0025] Assuming that the sign body 1 cannot deform, the continuous movement of the magnetic piston rod 3 towards the opening of the U-shaped seat 2 will obviously continuously expand the volume of the aforementioned enclosed space. Since the amount of air in this enclosed space is fixed, the constant increase in volume will directly lead to a decrease in pressure within the enclosed space. At this time, under the influence of atmospheric pressure and the pressure difference between the environment and the sign body 1, the marking part 11 is tightly pressed against the outer shell of the production equipment. Simultaneously, as the magnetic piston rod 3 slides towards the U-shaped seat 2, the upper and lower sides of the magnetic piston rod 3 will respectively generate a unidirectional scraping and cleaning action on the back of the sign body 1 and the surface of the production equipment outer shell, bringing out some impurities such as dust and fibers that are not visible to the naked eye to the outside of the enclosed space, further preventing gaps or air bubbles from forming on the bonding surface between the sign body 1 and the production equipment outer shell due to the presence of impurities.

[0026] To optimize sealing performance and protect the equipment surface, a sealing gasket 32 ​​can also be provided on the side of the magnetic piston rod 3 away from the plate body 1, i.e., at its lower end. For example... Figure 5 and Figure 6As shown in the back and split diagram, the sealing gasket 32 ​​is preferably made of fluororubber to withstand the challenges of oil and high temperatures in industrial environments. Fluororubber is resistant to oil and extreme temperatures, with a temperature range of -20°C to 200°C. On the lower surface of the sealing gasket 32, the side in contact with the equipment housing, micron-level anti-slip textures can be provided. The depth of these textures can be, for example, 0.02mm, 0.035mm, or 0.05mm. These fine textures effectively increase the static friction between the sealing gasket 32 ​​and the equipment housing, preventing the sealing gasket 32 ​​from slipping after the external force pulling the magnetic piston rod 3 disappears. To ensure that the sliding of the magnetic piston rod 3 does not affect the sealing performance of the enclosed space, a rubber sealing layer can be wrapped around the surface of its wedge-shaped portion 31. This sealing layer can fill the gap between the wedge-shaped portion 31 and the wedge-shaped groove 21 using its own elastic deformation, ensuring the integrity of the sealed space.

[0027] Furthermore, the magnetic piston rod 3 itself possesses magnetism, forming a unique double-sided magnetic coupling with the flexible magnetic plate body 1 and the iron production equipment shell. This magnetic attraction enhances the tightness of the fit between components, ensuring the airtightness of the enclosed space. On the other hand, after the magnetic piston rod 3 moves to the target position, the magnetic force effectively prevents it from shifting back due to equipment vibration or internal pressure recovery, thus acting as a self-locking mechanism. To ensure uniform force distribution across the entire mating surface and avoid localized gaps, the lower end face of the magnetic piston rod 3, or, when equipped with a sealing gasket 32, the lower end face of the sealing gasket 32, is preferably coplanar with the plane of the adhesive layer at the lower end of the U-shaped seat 2, i.e., on the same horizontal plane. This flush design ensures the airtightness of the enclosed space at the magnetic piston rod 3 and also allows the sealing gasket 32 ​​to effectively scrape and clean the equipment surface during the movement of the magnetic piston rod 3.

[0028] It is important to emphasize that in this embodiment, the adhesive, magnetic attraction, and negative pressure are not simply parallel functions, but rather constitute a deeply coupled and mutually supportive collaborative system. This system can effectively delay the failure process of any single component, especially the adhesive layer, and provide redundancy protection when one component's performance degrades. Specifically, the main function of the adhesive layer is to provide an initial, rigid positioning reference for the entire signage system. It firmly anchors the U-shaped base 2 to the equipment housing, defining precise boundaries and a sealing foundation for subsequent magnetic positioning and negative pressure formation. Without the initial fixation of the adhesive layer, relying solely on magnetic attraction, the U-shaped base 2 may experience slight movement under vibration, compromising the airtightness required to form negative pressure.

[0029] However, as mentioned earlier, the pure adhesive layer is at risk of fatigue aging under long-term vibration. In this case, the intervention of magnetic attraction and negative pressure significantly improves the working condition of the adhesive layer. Negative pressure adsorption, the magnetic attraction between the flexible magnetic plate 1 and the equipment casing, and the magnetic attraction between the magnetic piston rod 3 and the equipment casing generate a huge, uniformly distributed clamping force perpendicular to the equipment surface. This force tightly "presses" the plate 1 onto the equipment, greatly distributing the peeling and shear stresses acting on the adhesive layer. This allows the adhesive layer to shift from bearing the main load to primarily serving a positioning and auxiliary sealing function, and the significant reduction in its stress level directly slows down the fatigue aging process. This protects the sealing environment necessary to maintain negative pressure and indirectly protects the edges of the adhesive layer from repeated peeling stress.

[0030] Conversely, the stable substrate provided by the adhesive layer also ensures the effectiveness of the magnetic attraction and the integrity of the negative pressure space. If the adhesive layer completely fails, causing the U-shaped seat 2 to detach, the magnetic attraction and negative pressure will indeed be difficult to maintain the long-term fixation of the sign independently. However, the synergistic effect of the three greatly improves the overall lifespan and reliability of the system under harsh working conditions.

[0031] In summary, the safety production sign in this embodiment utilizes the synergistic effect of the flexible magnetic sign body 1, the adhesive layer and the U-shaped seat 2 with the wedge-shaped groove, and the magnetic piston rod 3 with the wedge-shaped part 31 and the sealing gasket 32, along with the pull rope 4, to construct a triple fixing system of "adhesive initial fixation, magnetic assisted positioning, and negative pressure tight adhesion." Its usage can be summarized as follows: first, the U-shaped seat 2 is initially fixed to the equipment surface through the adhesive layer, forming a reference frame; then, the magnetic piston rod 3 is inserted, causing its wedge-shaped part 31 to engage with the wedge-shaped groove 21; finally, the pull rope 4 is pulled, causing the magnetic piston rod 3 to slide and reduce the pressure in the enclosed space, thereby tightly, flatly, and without air bubbles adhered to the equipment. This triple fixing mechanism synergistically enhances reliability far exceeding that of a single fixing method, jointly ensuring the long-term service life and stability of the sign in harsh industrial environments.

[0032] Example 2: This embodiment provides a method for installing the safety production sign described in Embodiment 1. The method first involves gluing and fixing the U-shaped base 2 to the back edge of the sign body 1. This step is typically completed before the sign leaves the factory, forming a semi-finished assembly for easy on-site installation. Next, in step S2, the operator aligns the wedge-shaped portions 31 at both ends of the magnetic piston rod 3 with the opening of the U-shaped base 2 and engages them within its wedge-shaped grooves 21. Initially, the magnetic piston rod 3 is usually slid along the wedge-shaped grooves 21 to a position near the bottom of the U-shaped base 2 to allow sufficient travel space for subsequent expansion of the enclosed space. Simultaneously, the free end of the pull rope 4 connected to the side wall of the magnetic piston rod 3 needs to be straightened and ensured to extend beyond the U-shaped base 2 for easy gripping and pulling.

[0033] Step S3 is a crucial preparatory step for on-site installation. The operator peels off the release film from the adhesive layer on the underside of the U-shaped base 2, and then precisely fixes the entire assembly to the predetermined position on the production equipment housing using this adhesive layer. During this process, the adhesive joint between the U-shaped base 2 and the equipment housing must be pressed evenly to ensure full contact between the adhesive layer and the equipment surface, forming a preliminary and stable fixation. This preliminary fixation provides a reliable "foundation" for subsequent steps, preventing the magnetic piston rod 3 from shifting during the pulling process.

[0034] The final core step is S4. The operator smoothly pulls the rope 4 connected to the side wall of the magnetic piston rod 3 in a direction parallel to the equipment surface. This pulling action drives the magnetic piston rod 3 to slide from its initial position toward the opening end of the U-shaped seat 2 along the guide of the wedge groove 21. As the magnetic piston rod 3 moves, the volume of the enclosed space formed by the tension part 12 of the plate body 1, the U-shaped seat 2, the magnetic piston rod 3, and the production equipment shell changes, resulting in a significant decrease in the gas pressure within this space, forming a local negative pressure. Under the pressure difference between the atmospheric pressure and this negative pressure area, the marking part 11 of the plate body 1 is uniformly pressed against the surface of the equipment shell, while the tension part 12 on its side undergoes flexible stretching, allowing the marking part 11 to be pressed against the equipment surface. Throughout the bonding process, the double-sided magnetic coupling between the magnetic piston rod 3 and the plate body 1 and the production equipment shell continues to function. It not only enhances the tightness of the press, but more importantly, after the magnetic piston rod 3 moves into place, the magnetic attraction acts like a natural self-locking device, which can effectively resist the tendency of the equipment to move back due to vibration or internal pressure, ensuring the long-term stability of the bonding state.
