Description

Technical Field

[0001] This utility model relates to the field of warning device technology, specifically a telescopic warning device for aircraft refueling trucks. Background Technology

[0002] Safety is paramount during aircraft refueling operations. Aircraft refueling trucks need to operate in the complex environment of airports, surrounded by numerous personnel, other vehicles, and aircraft.

[0003] Traditional warning methods often use hard material warning signs, which, while effective to some extent, have many shortcomings. Hard material warning devices may scratch or damage the aircraft due to space constraints or improper operation at the work site. Therefore, a telescopic warning device for aircraft refueling trucks is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a retractable warning device for aircraft refueling vehicles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic warning device for an aircraft refueling vehicle, comprising a base, a fabric layer adhered to the top of the base, and a pull block fixed to the top of the fabric layer;

[0006] Several reflective strips for warning are sewn onto the outer side of the fabric layer; two mounting brackets are fixed to the bottom of the base; and several support rings are fixed to the inner wall of the fabric layer.

[0007] A notification component is provided on one side of the mounting bracket;

[0008] The prompting component includes a fixing frame, the fixing frame having a sliding groove inside, a sliding plate slidably connected to the inner side wall of the sliding groove, a sliding column fixed to one side of the bottom of the sliding plate, and the outer side of the sliding column passing through one side of the fixing frame and the mounting frame in sequence.

[0009] A limit plate is fixed at the middle of the bottom of the inner wall of the slide, a switch is installed at the bottom of the inner wall of the slide, and a buzzer is installed at the top of the fixing frame.

[0010] Preferably, the base is provided with a refueling pipe on one side, which is installed at the oil outlet of the aircraft refueling vehicle, and a connecting frame is installed on the outside of the refueling pipe.

[0011] Preferably, the bottom side of the mounting frame is connected to the connecting frame by bolts, and the fabric layer is cone-shaped.

[0012] Preferably, the diameter of the support rings increases from top to bottom. When several support rings are interlocked, the fabric layer is in a retracted state, and when several support rings are separated, the fabric layer is in an extended state.

[0013] Preferably, the aforementioned mounting bracket has a battery compartment inserted into one side, and a button battery is installed inside the battery compartment.

[0014] Preferably, as described above, a spring connects the bottom of the battery compartment to the top of the slide plate, and the bottom of the fixing frame is fixed to one side of the mounting frame.

[0015] Preferably, the output terminal of the button battery is electrically connected to the input terminal of the switch, and the output terminal of the switch is electrically connected to the input terminal of the buzzer.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0017] 1. When the warning device is deployed, multiple reflective strips extend along with the fabric layer, effectively alerting the surrounding area and improving safety at the work site. The reflective strips reflect light under illumination, enhancing the visibility of the warning and ensuring that nearby personnel can clearly see the warning signal. After refueling, the warning device can be easily retracted. Multiple support rings of different diameters interlock, allowing the fabric layer to retract compactly to the top of the base, significantly reducing the size of the warning device and facilitating storage and transportation. The telescopic warning device uses soft fabric and a retractable design, fundamentally avoiding the risk of hard-material warning devices scratching the aircraft, thus protecting its safety. Simply pulling or pressing the lever allows workers to easily deploy or retract the warning device, making setting and deactivating warnings during refueling operations quick and convenient.

[0018] 2. When the bolts connecting the mounting bracket and the connecting frame become loose, causing the gap between them to widen, the linkage of components such as the spring, sliding plate, and sliding column triggers the switch, which in turn causes the buzzer to sound an alarm. This allows staff to be informed of the loose bolts immediately, preventing more serious equipment failures or safety issues caused by undetected loose bolts. The buzzer's audible alarm proactively informs staff, reducing omissions and oversights compared to the need for staff to periodically and manually check for loose bolts, thus improving the safety and stability of equipment operation.

[0030] Example

[0031] Please see Figure 1-7 This utility model provides a technical solution: a telescopic warning device for an aircraft refueling truck, including a base 1, a fabric layer 3 bonded to the top of the base 1, a pull block 5 fixed to the top of the fabric layer 3, the fabric layer 3 being made of Oxford cloth; several reflective strips 4 for warning are sewn onto the outside of the fabric layer 3, the reflective strips 4 unfold as the fabric layer 3 extends, effectively warning the surroundings, two mounting brackets 6 are fixed to the bottom of the base 1, and several support rings 7 are fixed to the inner wall of the fabric layer 3, the support rings 7 being made of rubber or plastic;

[0032] A refueling pipe 8 is installed on one side of the base 1 at the oil outlet of the aircraft refueling vehicle. A connecting frame 9 is installed on the outside of the refueling pipe 8. The bottom side of the mounting frame 6 is connected to the connecting frame 9 by bolts. The fabric layer 3 is cone-shaped. The diameter of the support ring 7 increases from top to bottom to accommodate the contraction and expansion of the fabric layer 3. When several support rings 7 are interlocked, the fabric layer 3 is in a retracted state. When several support rings 7 are separated, the fabric layer 3 is in an extended state.

[0033] A prompting component 2 is provided on one side of the mounting bracket 6; the prompting component 2 includes a fixing bracket 21, a sliding groove 28 is provided inside the fixing bracket 21, a sliding plate 23 is slidably connected to the inner wall of the sliding groove 28, a sliding column 25 is fixed to one side of the bottom of the sliding plate 23, and the outer side of the sliding column 25 passes through the fixing bracket 21 and the mounting bracket 6 in sequence; the linkage of components such as the spring 22, the sliding plate 23, and the sliding column 25 triggers the switch 24, which in turn causes the buzzer 27 to sound a prompt, a limit plate 29 is fixed at the middle of the bottom of the inner wall of the sliding groove 28, the switch 24 is installed at the bottom of the inner wall of the sliding groove 28, and the buzzer 27 is installed at the top of the fixing bracket 21.

[0034] A battery compartment 26 is inserted into one side of the mounting bracket 21. A button battery is installed inside the battery compartment 26. A spring 22 connects the bottom of the battery compartment 26 to the top of the slide plate 23. The bottom of the mounting bracket 21 is fixed to one side of the mounting bracket 6. The buzzer 27 provides an audible prompt to inform the staff. Compared with the need for staff to manually check the bolts regularly, this reduces the omissions and oversights of manual inspection. The output terminal of the button battery is electrically connected to the input terminal of the switch 24. The bottom of the slide plate 23 is attached to the contact of the switch 24. When the slide plate 23 moves downward, the switch 24 is quickly triggered. The output terminal of the switch 24 is electrically connected to the input terminal of the buzzer 27.

[0035] Working principle: First, the mounting frame 6 is connected to the connecting frame 9 with bolts. Then, when the aircraft refueling truck is refueling, the staff only needs to pull the pull block 5 upward. The pull block 5 causes the fabric layer 3 to extend upward, so that the height of multiple support rings 7 increases and they separate from each other. At this time, multiple reflective strips 4 unfold with the fabric layer 3, which can warn the surrounding area.

[0036] Once the aircraft refueling truck has finished refueling, simply press the pull block 5. The pull block 5 will push the fabric layer 3, causing multiple support rings 7 to move downwards. Since the diameters of the multiple support rings 7 are different, the smaller diameter support ring 7 will fit inside the larger diameter support ring 7, causing the fabric layer 3 to retract to the top of the base 1, reducing the size of the warning device.

[0037] When the mounting bracket 6 and the connecting bracket 9 are connected by bolts, during daily use, if the connecting bolts loosen, the gap between the mounting bracket 6 and the connecting bracket 9 will increase. The spring 22 will push the slide plate 23 to slide downwards inside the slide groove 28, and at the same time push the bottom of the slide column 25 to fit against one side of the connecting bracket 9, so that the bottom of the slide plate 23 contacts the contact of the switch 24. The slide plate 23 will trigger the switch 24, and then the buzzer 27 will produce an audible warning to inform the staff that the bolts of the mounting bracket 6 of the warning device are loose and need to be checked.

[0038] In summary, when the warning device is deployed, multiple reflective strips 4 extend along with the fabric layer 3, effectively alerting the surrounding area and improving safety at the work site. The reflective strips 4 reflect light under illumination, enhancing the visibility of the warning and ensuring that surrounding personnel can clearly see the warning signal. After refueling, the warning device can be easily retracted. Multiple support rings 7, due to their different diameters, interlock, allowing the fabric layer 3 to retract compactly onto the top of the base 1, significantly reducing the size of the warning device and facilitating storage and transportation. The telescopic warning device uses soft fabric and a telescopic design, fundamentally avoiding the risk of hard-material warning devices scratching the aircraft, thus protecting its safety. By simply pulling or pressing the lever 5, workers can easily deploy or retract the warning device, making the setting and removal of warnings during refueling operations very quick and convenient.

[0039] When the bolts connecting the mounting bracket 6 and the connecting bracket 9 become loose, causing the gap between them to increase, the linkage of components such as the spring 22, the slide plate 23, and the sliding column 25 triggers the switch 24, which in turn causes the buzzer 27 to sound an alarm. This allows the staff to be informed of the loose bolts immediately, preventing more serious equipment failures or safety issues caused by the failure to detect the loose bolts in time. The sound alarm from the buzzer 27 proactively informs the staff, reducing omissions and oversights compared to the need for staff to manually check for loose bolts regularly, thus improving the safety and stability of equipment operation.
