Abstract
Description
Technical Field
[0001] This utility model relates to the field of flagpole technology, and in particular to a folding universal warning flagpole. Background Technology
[0002] During aviation fuel refueling operations, refueling trucks need to move frequently on the apron and deliver fuel to aircraft through exposed refueling hoses. Due to the complex apron environment, which involves various vehicles, ground staff, and equipment working together, the refueling hoses, when extended, can easily become potential collision points. Without appropriate warning and protective measures, this can easily lead to fuel leaks, equipment damage, or even safety accidents.
[0003] Traditional warning and protective measures mainly rely on simple markings such as fixed warning signs and cones. While these methods serve a warning purpose, they also have certain limitations. For example, visibility is insufficient; static signs are difficult to notice in time at night, in low light, or in inclement weather conditions. Adaptability is poor; the warning position cannot be flexibly adjusted according to apron space requirements, and its effectiveness is easily affected by obstruction from ground support equipment. There is no collision trigger mechanism; if the refueling hose is accidentally touched, the emergency warning cannot be automatically activated, delaying risk response. There is no collision reset mechanism; when the warning device is collided with, it is difficult for it to automatically reset to the warning position, making it difficult to properly warn surrounding equipment and personnel. Therefore, there is an urgent need to design a retractable audible and visual alarm warning flagpole to improve the safety of the aviation fuel refueling process. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a foldable universal warning flagpole that is highly adaptable to the environment, has active warning and automatic reset functions, and can improve the safety of the aviation fuel refueling process.
[0005] To achieve the above objectives, this utility model provides a folding universal warning flagpole, including an audible and visual alarm, a fixed rod, a connecting rod, an elastic element, a movable rod, and several warning components. The control switch of the audible and visual alarm and several warning components are all located at the top of the movable rod. The elastic element is located at the bottom of the movable rod. The end of the elastic element away from the movable rod is connected to the connecting rod. The connecting rod is movably and limitably installed at the top of the fixed rod. The fixed rod is located near the end of the refueling pipe.
[0006] Preferably, the top surface of the fixed rod has a mounting hole for the connecting rod to extend into, and the wall of the mounting hole has an adjustment groove and a notch. The connecting rod is detachably connected to the fixed rod through a locking member passing through the adjustment groove, and the notch is used to accommodate the connecting rod.
[0007] Preferably, the bottom end of the movable rod and the top end of the connecting rod are respectively fitted with sleeves into which the elastic element extends, and fasteners for locking the elastic element are detachably mounted on the sleeves.
[0008] Preferably, the two sleeves are integrally formed with the movable rod and the connecting rod, and the elastic element is a spring.
[0009] Preferably, the top of the movable rod is provided with a mounting base, and the mounting base is provided with a control switch for the audible and visual alarm. The mounting base is provided with a plurality of warning components evenly and at intervals along its circumference. Each of the warning components includes a horizontal bar and a warning flag. One end of the horizontal bar is rotatably mounted on the mounting base, and the other end of the horizontal bar passes through the warning flag.
[0010] Preferably, a plurality of the warning components further includes a vertical bar, which is disposed on the horizontal bar and perpendicular to the horizontal bar, and the vertical bar passes through the warning flag.
[0011] Preferably, the outer walls of the fixed rod, connecting rod, and movable rod are all coated with reflective paint; the bottom of the fixed rod is provided with a connecting plate for detachable connection with the refueling pipe fixing bracket.
[0012] Beneficial effects:
[0013] 1. In this utility model of folding universal warning flagpole, several warning components can remind surrounding vehicles, ground staff or equipment that refueling is in progress, effectively preventing them from accidentally entering the refueling area, ensuring the warning effect on the surrounding environment, and improving the safety of the aviation fuel refueling process.
[0014] 2. During use, the folding universal warning flagpole of this utility model can position several warning components above the refueling pipe through the movable pole, thereby expanding the visibility range of the warning components by taking advantage of the height. This not only improves visibility, but also meets the needs of use at night, in low light or in bad weather conditions when used in conjunction with an audible and visual alarm. It is reliable in use.
[0015] 3. During use, the staff can adjust the spatial placement of several warning components according to the actual usage situation of this utility model folding universal warning flagpole. This not only avoids the warning components being blocked by ground equipment or personnel, thus affecting the effectiveness of use, but also improves the adaptability to the surrounding environment.
[0016] 4. When the folding universal warning flagpole of this utility model collides, the movable pole can automatically reset through the elastic element, thereby ensuring that the warning effect of several warning components on the movable pole remains effective, and no manual intervention or readjustment of the placement of the movable pole is required, which reduces the labor intensity of the staff and is convenient to use.
[0017] 5. In this utility model of a folding universal warning flagpole, by setting the control switch of the audible and visual alarm at the top of the movable pole, when the movable pole is collided and tilted, the control switch of the audible and visual alarm can make contact with the external structure to cause the main body of the audible and visual alarm to emit a collision alarm.

[0018] 6. In this utility model of folding universal warning flagpole, by installing the fixing rod onto the refueling pipe fixing bracket, several warning components can move synchronously with the head of the refueling pipe. That is, no matter how the refueling pipe extends, turns, or moves, several warning components are always close to the head of the refueling pipe, thereby marking the dynamic range of movement of the refueling pipe head in real time and ensuring the warning effect on the surrounding environment.
[0019] 7. When the folding universal warning flagpole of this utility model is not in use, the connecting rod is movably installed on the top of the fixed rod, so that the staff can adjust the movable rod, elastic element and connecting rod relative to the fixed rod, so that the movable rod can be placed on the refueling pipe fixing frame, thereby reducing the space occupied, facilitating handling, transportation and management, and preventing this utility model from obstructing other equipment or making incorrect warning information on the apron.

[0031] Example 1:
[0032] This utility model proposes a foldable universal warning flagpole 100.
[0033] In one embodiment of this utility model, the folding universal warning flagpole 100 includes an audible and visual alarm, a fixed rod 1, a connecting rod 2, an elastic element 3, a movable rod 4, and several warning components. The control switch of the audible and visual alarm and several warning components are all located on the top of the movable rod 4. An elastic element 3 is located at the bottom of the movable rod 4. The end of the elastic element 3 away from the movable rod 4 is connected to the connecting rod 2. The connecting rod 2 is movably and limitedly installed on the top of the fixed rod 1. The fixed rod 1 is located near the end of the refueling pipe.
[0034] Specifically, such as Figures 1 to 3 As shown, in the folding universal warning flagpole 100 of this utility model, since the top of the movable pole 4 is equipped with several warning components (such as reflective flags, LED lights, etc.), during the refueling process, the operator raises the movable pole 4 to a preset position, placing the warning components above the refueling pipe. This height advantage expands the visibility range of the warning components, improving visibility. Furthermore, by cooperating with an audible and visual alarm, it meets the needs of use at night, in low light, or in adverse weather conditions, ensuring reliable operation. Moreover, the warning components can be installed on the movable pole 4 using a rotating snap-fit method, such as by bolting. The operator can adjust the spatial placement of the warning components according to actual usage, thus not only preventing obstruction by ground equipment or personnel, but also improving adaptability to the surrounding environment.
[0035] Understandably, since the bottom of the movable lever 4 is provided with an elastic element 3, the end of the elastic element 3 away from the movable lever 4 is connected to the connecting rod 2, and the connecting rod 2 is movably and limitedly installed on the top of the fixed rod 1, the movable and limited connection between the connecting rod 2 and the fixed rod 1 can be a damped hinge or a ball joint, etc., so that the connecting rod 2 can rotate relative to the fixed rod 1, and the movable lever 4 can rotate synchronously with the connecting rod 2 under the action of the elastic element 3. This allows the staff to raise the movable lever 4 to a preset position when refueling is required, and to remind surrounding vehicles, ground staff or equipment that refueling is in progress through several warning components, effectively preventing them from accidentally entering the refueling work area, ensuring the warning effect on the surrounding environment, and improving the safety of the refueling process. Furthermore, when the folding universal warning flagpole 100 of this utility model collides, the elastic element 3 between the movable pole 4 and the connecting rod 2 allows the movable pole 4 to automatically reset after the collision, thereby ensuring the continued effectiveness of the warning effect of the warning components on the movable pole 4 without manual intervention or readjustment of the placement of the movable pole 4, reducing the labor intensity of the staff and making it convenient to use. At the same time, since the top of the movable pole 4 is equipped with a control switch for an audible and visual alarm, and the body of the audible and visual alarm can be installed on the movable pole 4 or the refueling vehicle, when the movable pole 4 is collided and tilted, the control switch of the audible and visual alarm will collide with the external structure, causing the body of the audible and visual alarm to emit a collision alarm, thereby actively warning the surrounding equipment or ground staff, facilitating a rapid response after a collision, further improving the safety of the aviation fuel refueling process, reducing the probability of secondary accidents, and ensuring reliable use.
[0036] It should be noted that during the refueling process, in order to improve the connection stability between the refueling hose tip and the aircraft fuel tank refueling interface, a refueling hose fixing bracket 200 is usually used to support the refueling hose tip. Therefore, in actual use, the folding universal warning flagpole 100 of this utility model can be installed by the operator using bolts or other methods to attach the fixing rod 1 to the refueling hose fixing bracket 200. This allows several warning components to move synchronously with the refueling hose tip. That is, no matter how the refueling hose extends, turns, or moves, the warning components are always positioned close to the refueling hose tip. This allows for real-time marking of the dynamic range of movement of the refueling hose tip, ensuring a warning effect on the surrounding environment. In addition, when the folding universal warning flagpole 100 of this utility model is not in use, since the connecting rod 2 is movably installed on the top of the fixed rod 1, the staff can adjust the movable rod 4, the elastic element 3 and the connecting rod 2 relative to the fixed rod 1, so that the movable rod 4 can be placed on the refueling pipe fixing frame 200, thereby reducing the space occupied, facilitating handling, transportation and management, and preventing the folding universal warning flagpole 100 of this utility model from obstructing other equipment or making incorrect warning messages on the apron.
[0037] In one embodiment, the top surface of the fixed rod 1 has a mounting hole 5 for the connecting rod 2 to extend into. The wall of the mounting hole 5 has an adjusting groove 6 and a notch 7. The connecting rod 2 is detachably connected to the fixed rod 1 via a locking member passing through the adjusting groove 6, and the notch 7 is used to accommodate the connecting rod 2. Specifically, as shown... Figure 1 and Figure 3 As shown, the locking component can be a bolt connection, as is common in existing technologies. This not only ensures that the connecting rod 2 is securely installed in the mounting hole 5, but also allows the connecting rod 2 to rotate relative to the fixed rod 1. The structural design is simple and reasonable. Understandably, when refueling is required, the operator lifts the movable rod 4 and rotates it to a preset position. At this time, the movable rod 4, connecting rod 2, and fixed rod 1 are coaxially aligned, allowing the connecting rod 2 to slide towards the fixed rod 1 within the mounting hole 5. That is, the connecting rod 2 and the mounting hole 5 are engaged, and the locking component moves synchronously to one end of the adjusting groove 6. Under the action of the wall of the mounting hole 5, the connecting rod 2 is circumferentially limited, effectively preventing the connecting rod 2 and the movable rod 4 from tipping over during use, thus improving the safety of the connecting rod 2, the movable rod 4, and several warning components. The structure is ingenious and reasonable, providing stable support and ensuring a good warning effect on the surrounding environment. Furthermore, after refueling, when the folding universal warning flagpole 100 is no longer needed, workers can lift the movable rod 4 and connecting rod 2 away from the fixed rod 1. At this time, the locking component moves synchronously to the other end of the adjusting groove 6. Because the mounting hole 5 has a notch 7 on its wall, the connecting rod 2 can rotate and be accommodated within the notch 7. This allows for the rotation and storage of the connecting rod 2, movable rod 4, and several warning components, reducing space occupation and making operation simple and convenient.
[0038] In one embodiment, the bottom end of the movable rod 4 and the top end of the connecting rod 2 are respectively equipped with sleeves 8 into which the elastic element 3 extends. Fasteners for locking the elastic element 3 are detachably mounted on the sleeves 8. Specifically, as shown... Figure 1 and Figure 3 As shown, by fitting both ends of the elastic element 3 into two sleeves 8 respectively, and installing fasteners on the two sleeves 8, the fasteners can be bolts or other existing materials. Bolts are easy to install and remove and are readily available. The fasteners connect and limit the two ends of the elastic element 3, thereby ensuring the stability of the installation of the elastic element 3 and ensuring the automatic reset effect of the movable rod 4 when it is hit, making it reliable in use.
[0039] In one embodiment, such as Figure 1 and Figure 3As shown, the two sleeves 8 are integrally formed with the movable rod 4 and the connecting rod 2, respectively, and the elastic element 3 is a spring. This eliminates the assembly steps between the two sleeves 8 and the movable rod 4 and the connecting rod 2, avoids assembly gaps, eliminates assembly errors, and is easy to manufacture. In addition, the elastic element 3 is made of a spring, which has the characteristics of compact structure, easy material sourcing, and large elastic deformation force, thus facilitating the automatic reset effect of the movable rod 4 and ensuring reliable use.
[0040] In one embodiment, a mounting base 9 is provided at the top of the movable rod 4. A reset switch for the audible and visual alarm is provided on the mounting base 9. Several warning components are evenly and spaced along the circumference of the mounting base 9. Each warning component includes a horizontal bar 10 and a warning flag 11. One end of the horizontal bar 10 is rotatably mounted on the mounting base 9, and the other end of the horizontal bar 10 passes through the warning flag 11. Specifically, as... Figures 1 to 3 As shown, by evenly spaced and circumferentially spaced several warning components along the mounting base 9, these components can provide all-around warnings to the surrounding environment from the mounting base 9. The structural design is simple and reasonable. Furthermore, since one end of the crossbar 10 in the warning components is rotatably mounted on the mounting base 9, workers can flexibly adjust the display angle of the warning flag 11, expanding the warning range, eliminating blind spots, and improving visibility. It should be noted that the warning flag 11 has an identification structure on its surface. The identification structure can be made of highly reflective fluorescent material and forms standardized warning signs through specific patterns, text, or color combinations, effectively solving the technical problems of unclear information transmission and limited visibility distance in traditional warning devices. In addition, the crossbar 10 can be made of silicone-coated memory metal core, allowing workers to manipulate the crossbar 10 to adjust the spatial position of the warning flag 11, thus preventing the warning flag 11 from being obstructed by external structures, further eliminating blind spots, and enhancing environmental adaptability, flexibility, and convenience of use.
[0041] In one embodiment, the warning components further include a vertical bar 12, which is disposed on and perpendicular to the horizontal bar 10, and passes through the warning flag 11. Specifically, as shown... Figure 1 and Figure 2 As shown, since the vertical pole 12 and the horizontal pole 10 are perpendicular to each other, the vertical pole 12 and the horizontal pole 10 can form a "right-angle" support structure, which allows the warning flag 11 to always remain in an unfolded state. This not only effectively prevents the warning flag 11 from getting tangled or folded due to changes in wind force and reduces the swing amplitude of the warning flag 11, ensuring the continuous visibility of the warning flag 11, but also provides a more stable and efficient safety warning guarantee for aviation fuel refueling operations.
[0042] In one embodiment, the outer walls of the fixed rod 1, connecting rod 2, and movable rod 4 are all coated with reflective paint; the bottom of the fixed rod 1 is provided with a connecting plate 13 for detachable connection with the refueling pipe fixing bracket 200. Specifically, as shown... Figures 1 to 3 As shown, by coating the outer walls of the fixed rod 1, connecting rod 2, and movable rod 4 with a high-reflectivity reflective paint (such as using glass microspheres or prism reflection technology), the visibility of the folding universal warning flagpole 100 of this utility model at night and in low-visibility environments can be significantly improved. Simultaneously, the reflective paint extends the service life of the fixed rod 1, connecting rod 2, and movable rod 4 under sun and rain conditions. Furthermore, when the folding universal warning flagpole 100 needs to be installed on the refueling pipe mounting bracket 200, workers can connect the connecting plate 13 to the refueling mounting bracket using bolts or other methods, thereby achieving rapid installation of the fixed rod 1. The structural design is simple and reasonable, and it is easy to assemble and disassemble, facilitating maintenance.
[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
