[0030] Working principle

[0031] Installation phase

[0032] Building the support structure: Install the telescopic rod 15 to the bottom of the load-bearing box 4. The detachable connection design between the two makes the operation convenient. Next, connect the support rod 14 and the positioning plate 11 in sequence to quickly build a stable support frame. This modular splicing method requires no special tools, greatly shortening the installation time.

[0033] Fixed main identification board: insert the main identification board 1 into the observation cover 2 along the card slot 3, which not only plays a positioning role, but also facilitates the replacement of the identification board. Then install the sealing bottom plate 8, which is detachably connected with the observation cover 2, can effectively seal the main identification board 1 in the observation cover 2, avoid its erosion by the external environment, and ensure the clear and lasting warning information.

[0034] Tighten and stabilize the whole: insert the connecting head 10 into the corresponding connecting pipe 13 on the positioning plate 11, operate the positioning and pressing guide assembly 7, and press the tensioning rope 9. The winding roller 5 is transmission connected with the transmission roller 6 in the bearing box 4, when the tensioning rope 9 is affected by the positioning and pressing guide assembly 7, the tensioning rope 9 between the bearing box 4 and the positioning plate 11 is gradually tightened, thereby greatly improving the stability of the whole support.

[0035] Use stage

[0036] In the use process, the support structure composed of the bearing box 4, the telescopic rod 15, the supporting rod 14 and the positioning plate 11 provides stable support for the identification board, ensuring that it remains upright in various environments. The main identification board 1 sealed in the observation cover 2 clearly displays the fire warning information and continuously plays a warning role.

[0037] Recycling stage

[0038] When the identification board needs to be recycled, rotate the transmission roller 6, since the transmission roller 6 is transmission connected with the winding roller 5, the winding roller 5 rotates synchronously. During the rotation of the winding roller 5, the tensioning rope 9 is gradually wound back for recycling, realizing the convenient recycling of the tensioning rope 9. Then, according to the reverse order of installation, sequentially disassemble the sealing bottom plate 8, the main identification board 1, the connecting head 10 and the connecting pipe 13, and the telescopic rod 15, the supporting rod 14 and the positioning plate 11, complete the whole recycling work of the identification board.

[0039] Example 2

[0040] As Figures 1 to 3As shown, an easy-to-install fire safety warning sign includes a carrying box 4, an observation cover 2 with an open bottom connected to one side of the carrying box 4, a card slot strip 3 connected to the top inside the observation cover 2, a main signboard 1 provided in the card slot strip 3, a sealing bottom plate 8 detachably connected to the opening of the observation cover 2, transmission rollers 6 rotatably connected to both sides inside the carrying box 4, a winding roller 5 rotatably connected to the carrying box 4 on the other side of the transmission rollers 6, a tensioning rope 9 penetrating through the carrying box 4 and wound around the winding roller 5, a connecting head 10 connected to the penetrating end of the tensioning rope 9, positioning and compression guide assemblies 7 connected to both sides of the carrying box 4 for compressing the tensioning rope 9, a telescopic rod 15 detachably connected to the bottom of the carrying box 4, a support rod 14 detachably connected to the telescopic rod 15, a positioning plate 11 detachably connected to the support rod 14, and a connecting pipe 13 corresponding to the connecting head 10 and detachably connected to the opposite side of the positioning plate 11 and the carrying box 4.

[0041] The observation cover 2 is a transparent product.

[0042] What are the benefits of the above arrangement:

[0043] Ensure effective delivery of warning information

[0044] The transparent observation cover 2 does not block the warning content on the main signboard 1, and passing personnel can clearly and intuitively obtain the fire safety information conveyed by the sign. Whether in an indoor environment with sufficient light or in a complex outdoor lighting condition, the transparent observation cover 2 can maximize the visibility of the main signboard 1, improve the warning effect, enable people to notice the fire safety prompt at the first time, and reduce the risk of fire.

[0045] Convenient maintenance and inspection

[0046] During routine maintenance, staff can directly check the status of the main signboard 1, such as whether there is damage, fading, etc., without disassembling the observation cover 2. This convenience greatly improves maintenance efficiency and saves labor and time costs. At the same time, the quick inspection process also ensures that the sign is always in good working condition and continuously plays a fire safety warning role.

[0047] Enhance overall aesthetics

[0048] The transparent observation cover 2 makes the sign more transparent as a whole, does not destroy the original design style of the sign, but instead adds a simple and elegant beauty. This helps the sign to better integrate into the environment of various places, whether in modern commercial buildings or natural landscape areas, without appearing conspicuous, meeting the needs of fire safety and also taking into account environmental harmony.

[0049] Prolong the service life

[0050] The observation cover 2 itself plays a protective role for the main identification board 1. The transparent material achieves protection while not causing aging differences due to uneven lighting caused by shielding. Moreover, the transparent observation cover 2 can effectively block dust, rain, ultraviolet rays, and other erosions to the main identification board 1, prolonging the service life of the main identification board 1 and reducing replacement costs.

[0051] The clamping groove strip 3 is made of rubber.

[0052] What are the benefits of the above settings?

[0053] Strengthen the fixing effect

[0054] Rubber has excellent flexibility and elasticity. When the main identification board 1 is inserted, the clamping groove strip 3 will tightly adhere to the edge of the main identification board 1 due to its own elasticity. Even if it is shaken by external force, the main identification board 1 is difficult to displace, effectively avoiding the situation that the warning information cannot be normally displayed due to shaking and falling off, and ensuring that the fire warning sign plays a stable role.

[0055] Protect the identification board

[0056] During the process of inserting or removing the main identification board 1, the clamping groove strip 3 made of rubber can avoid scratching the surface of the main identification board 1, preventing scratches from damaging the appearance of the identification board and affecting the recognition of the warning information. Moreover, in the long-term use process, the buffering characteristics of rubber can absorb the impact force transmitted to the main identification board 1 due to external vibration or collision, reducing the risk of damage to the main identification board 1 and prolonging its service life.

[0057] Reduce installation difficulty

[0058] The flexibility of rubber allows the main identification board 1 to be inserted into the clamping groove strip 3 without precise alignment, allowing for a certain degree of deviation. The installation personnel can more easily install the main identification board 1 into place, greatly saving installation time and improving installation efficiency. At the same time, this also reduces the requirement for professional skills of the installation personnel, and even non-professionals can successfully complete the installation.

[0059] Improve environmental adaptability

[0060] Rubber itself has good weather resistance. Whether in a high-temperature, humid environment, or in a cold, dry climate, the rubber clamping groove strip 3 can maintain stable performance and will not deform or harden due to environmental changes. It always provides reliable fixation for the main identification board 1, ensuring that the fire warning sign works normally in different environments.

[0061] Reduce maintenance costs

[0062] Due to the protection of the rubber slot strip 3 to the main identification plate 1 and the stable performance of itself, the damage frequency of the main identification plate 1 and the slot strip 3 is reduced, the cost of replacement and maintenance is reduced, and the safety risk that the fire warning sign cannot be normally used due to maintenance is also reduced.

[0063] As shown in Figure 4 The positioning and pressing guide assembly 7 includes a guide groove body 701 arranged in the bearing box 4, and the tensioning rope 9 penetrates the guide groove body 701. The guide groove body 701 is provided with a positioning sleeve 705 connected with the inner wall of the bearing box 4. The positioning sleeve 705 is threadedly connected with a push rod 703 penetrating the bearing box 4. The penetrating end of the push rod 703 is rotationally connected with a pressing plate 702 inserted into the guide groove body 701. The end of the push rod 703 away from the pressing plate 702 is connected with a rotating head 704 arranged outside the bearing box 4. The push rod 703 pushes the pressing plate 702 to press the tensioning rope 9 penetrating the guide groove body 701.

[0064] What are the benefits of the above settings:

[0065] Precise guidance: The guide groove body 701 provides a precise guide path for the tensioning rope 9, ensuring that the tensioning rope 9 does not deviate or shake during movement, allowing the tensioning rope 9 to be arranged according to the predetermined direction and position, thereby ensuring the stability and reliability of the entire sign structure.

[0066] Convenient adjustment: By rotating the rotating head 704, the push rod 703 can be easily controlled to advance and retreat in the positioning sleeve 705. Since the push rod 703 is threadedly connected with the positioning sleeve 705, this threaded transmission method has good transmission accuracy and self-locking performance. By slightly rotating the rotating head 704, the pressing degree of the pressing plate 702 to the tensioning rope 9 can be accurately adjusted to adapt to different installation environments and tensioning needs.

[0067] Effective pressing: The push rod 703 pushes the pressing plate 702 to press the tensioning rope 9, providing sufficient friction to prevent the tensioning rope 9 from slipping during use, ensuring that the tension between the bearing box 4 and the positioning plate 11 remains stable, thereby enhancing the stability of the entire support structure, allowing the fire warning sign to remain upright and stable under various environmental conditions, effectively playing its warning role.

[0068] Compact structure: The guide groove body 701, the positioning sleeve 705, the push rod 703, the pressing plate 702, and the rotating head 704 cooperate with each other to form a compact overall structure, occupying a small space and being reasonably arranged in the bearing box 4, which does not affect the other functions of the bearing box 4, and realizes efficient positioning, pressing, and adjustment of the tensioning rope 9, improving the space utilization.

[0069] Easy to maintain: the components of this structure are relatively independent, and the connection is simple, when maintenance or replacement is needed, it is convenient for workers to operate. For example, if the pressing plate 702 or the push rod 703 is worn or damaged, it can be easily disassembled and replaced, without affecting other parts of the entire sign, reducing maintenance cost and difficulty.

[0070] The push rod 703 is integrally made with the rotating head 704.

[0071] What are the benefits of the above settings:

[0072] Enhance structural stability: integrally made avoids the problems of looseness, gap and other connection methods between the push rod and the rotating head, making them form a stable whole. When rotating the rotating head to push the push rod, it can ensure that the force transmission is more direct and stable, and the pressing effect of the pressing plate on the tensioning rope will not be affected by the instability of the connection, ensuring the reliable performance of the positioning and pressing guide assembly.

[0073] Improve transmission efficiency: without energy loss of intermediate connection link, the rotation of the rotating head can be more efficiently converted into the linear motion of the push rod, making it easier and more accurate for the operator to adjust the position of the pressing plate. The integrally made structure reduces friction and jamming in the force transmission process, improving the smoothness of the entire adjustment process.

[0074] Example 3

[0075] As shown in Figures 1 to 3 , an easy-to-install fire warning sign includes a bearing box 4, one side of the bearing box 4 is connected with an open-bottom observation cover 2, the top of the observation cover 2 is connected with a clamping groove strip 3, the clamping groove strip 3 is inserted with a main sign plate 1 arranged in the clamping groove strip 3, the opening of the observation cover 2 is detachably connected with a sealing bottom plate 8, both sides of the bearing box 4 are rotatably connected with transmission rollers 6, one side of the transmission rollers 6 penetrates the bearing box 4, the other side of the transmission rollers 6 is drivingly connected with a winding roller 5 rotatably connected with the bearing box 4, the winding roller 5 is wound with a tensioning rope 9 penetrating the bearing box 4, the penetrating end of the tensioning rope 9 is connected with a connecting head 10, both sides of the bearing box 4 are connected with a positioning and pressing guide assembly 7 for pressing the tensioning rope 9, the bottom of the bearing box 4 is detachably connected with an extension rod 15, the extension rod 15 is detachably connected with a supporting rod 14, the supporting rod 14 is detachably connected with a positioning plate 11, the positioning plate 11 is connected with a connecting pipe 13 corresponding to the connecting head 10 on the opposite side of the bearing box 4, and the connecting pipe 13 is detachably connected with the corresponding connecting head 10.

[0076] The tensioning rope 9 is a steel wire rope.

[0077] What are the benefits of the above settings:

[0078] High strength and high load-bearing capacity: Steel wire rope has excellent tensile strength, can withstand larger tension without easy breaking. In the fire warning sign, it can effectively connect and tighten the bearing box 4 with the positioning plate 11, ensuring that the sign can maintain a stable upright state under various environmental conditions, including strong wind, vibration, etc., and will not cause the sign to fall or damage due to the breaking of the tensioning rope, thus ensuring its normal warning function.

[0079] Good wear resistance and corrosion resistance: Steel wire rope usually undergoes special surface treatment, has good wear resistance and corrosion resistance. In outdoor environments, even if exposed to air for a long time, subjected to rain, dust, ultraviolet rays and other natural factors, and friction with other parts, the steel wire rope can maintain good performance and is not prone to wear, rust and other problems, prolonging the service life of the tensioning rope and reducing the frequency and cost of maintenance and replacement.

[0080] Moderate flexibility and elasticity: Steel wire rope has both flexibility and elasticity, which can be easily bent and arranged during installation to adapt to different installation positions and angle requirements, and can also absorb part of the energy through elastic deformation when subjected to external impact, thereby reducing damage to other parts of the sign and helping to maintain the stability of the tension force.

[0081] High reliability and safety: Due to the high strength and stability of steel wire rope, using steel wire rope as a tensioning rope can provide reliable support and fixation for the fire warning sign, enhancing the safety of the entire sign system. In emergency situations such as fire, the sign can maintain normal display status, providing accurate warning information to people, helping to guide personnel evacuation and smooth conduct of fire rescue work.

[0082] The bearing box 4 is screw-threadedly connected with the telescopic rod 15, the telescopic rod 15 is screw-threadedly connected with the support rod 14, the support rod 14 is screw-threadedly connected with the positioning plate 11, and the connecting pipe 13 is screw-threadedly connected with the connecting head 10.

[0083] What are the benefits of the above arrangement?

[0084] Convenient assembly and disassembly: The screw-threaded connection method makes it relatively easy to assemble and disassemble the components. When installing the fire warning sign, workers can easily connect the bearing box 4 with the telescopic rod 15, the telescopic rod 15 with the support rod 14, the support rod 14 with the positioning plate 11, and the connecting pipe 10 with the connecting head 13 by rotating the components. Similarly, when the sign needs to be repaired, replaced or transported, these components can be easily disassembled, making it easy to operate and improving work efficiency.

[0085] Stable and reliable connection: threaded connection can provide a more tight and stable connection. During use, the friction between the threads can effectively prevent relative displacement or loosening between the components, ensuring that the fire warning sign can maintain the stability of the overall structure under various environmental conditions. This stable connection can withstand certain external forces and vibrations, and is not prone to tilting, shaking or even collapsing of the sign due to loose connection, ensuring the normal use and warning effect of the sign.

[0086] Height adjustability: since the bearing box 4 and the telescopic rod 15, the telescopic rod 15 and the support rod 14 are all threaded, by rotating the telescopic rod 15 and the support rod 14, the height of the entire sign can be easily adjusted. This adjustability allows the sign to adapt to different installation environments and usage requirements, such as in different height buildings or places, the sign can be adjusted to the best visible height according to the actual situation, so as to better play its warning role.

[0087] The positioning plate 11 is provided with symmetrically distributed positioning grooves 12.

[0088] What are the benefits of the above settings:

[0089] Precise positioning: the positioning grooves 12 can provide accurate positioning for components that need to be installed on the positioning plate 11, ensuring that these components are installed in the correct position, ensuring the accuracy and stability of the entire structure. For example, other components connected to the positioning plate 11 can be accurately installed by embedding the positioning grooves 12, avoiding installation position deviation, so that each part of the fire warning sign can be correctly assembled and cooperated, effectively playing its function.

[0090] Enhanced stability: symmetrically distributed positioning grooves 12 can make the positioning plate 11 more balanced in terms of bearing weight and stress. When objects are connected to the positioning plate 11 through the positioning grooves 12, the force can be evenly distributed on the positioning plate 11, reducing the possibility of deformation, tilting or damage caused by uneven stress, improving the stability of the entire positioning plate 11 and the fire warning sign structure connected to it, so that it can better withstand external pressure and tension.

[0091] Convenient installation: installers can directly align the components with the positioning grooves 12 for installation, without the need for additional measurement or marking, simplifying the installation process and improving installation efficiency. The symmetrical distribution design also facilitates the identification and operation of installers, reducing the difficulty of installation, even in dim light or limited space, the installation work can be completed more accurately.

[0092] For example, Figure 5As shown, the telescopic rod 15 comprises a plug-in pipe 151, a sleeve pipe 153 plugged with the plug-in pipe 151, the plug-in end of the plug-in pipe 151 is connected with symmetrically distributed spring compression plugs 152, and the two sides of the sleeve pipe 153 are provided with a plurality of groups of positioning holes 154 distributed equidistantly from top to bottom, and the spring compression plugs 152 are plugged with the corresponding positioning holes 154.

[0093] What are the benefits of the above arrangement:

[0094] Highly flexible and adjustable: With the help of the plurality of groups of positioning holes 154 distributed equidistantly from top to bottom, and the symmetrically distributed spring compression plugs 152, the user only needs to press the spring compression plugs 152 to make them disengage from the current positioning hole 154, move the plug-in pipe 151 in the sleeve pipe 153 to the appropriate position, and then release the spring compression plugs 152 to make them engage in the new positioning hole 154, so as to accurately adjust the length of the telescopic rod 15. This makes the fire warning signboard adaptable to different height requirements, such as in high factory buildings or low passages, etc. The signboard can be ensured to be at the best visible height, fully playing the warning role.

[0095] Convenient and efficient installation: The automatic rebounding feature of the spring compression plugs 152 makes the connection operation of the plug-in pipe 151 and the sleeve pipe 153 not need to rely on any tools. The installer only needs to insert the plug-in pipe 151 into the sleeve pipe 153, and the spring compression plugs 152 will automatically engage in the positioning hole 154, completing quick positioning and fixing, greatly shortening the installation time and improving work efficiency.

[0096] Stable and reliable connection: The spring compression plugs 152 and the positioning holes 154 are tightly plugged, and under the action of the spring force, a large friction force is formed between them, effectively preventing the plug-in pipe 151 and the sleeve pipe 153 from sliding or accidentally disengaging. Even if the fire warning signboard is vibrated or impacted by external force during use, the telescopic rod 15 can remain stable, ensuring the safety and reliability of the entire signboard structure.

[0097] Convenient storage and transportation: When storing and transporting the fire warning signboard, the plug-in pipe 151 can be completely retracted into the sleeve pipe 153 by pressing the spring compression plugs 152, greatly reducing the overall volume of the telescopic rod 15, reducing transportation and storage costs, and also avoiding damage to the telescopic rod during handling due to its excessive length.

[0098] The examples made by the present utility model are not a limitation on the implementation modes. Based on the above description, other different forms of changes or variations can be made by those skilled in the art, and all the implementation modes do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present utility model.
