Description

Technical Field

[0001] The invention relates to the technical field of aircraft refueling guns, in particular to a universal aircraft refueling gun which can stop automatically. Background Art

[0002] Aircraft refueling trucks are generally equipped with gravity refueling reel hoses and gravity refueling guns for gravity refueling of aircraft. The gravity refueling gun must be fixed with an interlocking brake sensor for easy access. When the refueling gun is taken out, the vehicle brakes, and when the refueling gun is returned, the brakes are released. In addition, aircraft fuel generally has two types: aviation kerosene and aviation gasoline. Due to the different characteristics of the two fuels, the gravity refueling gun heads used for refueling are different, and mixing is not allowed to avoid danger.

[0003] However, when the aircraft is refueled by gravity, the refueling gun is directly placed in the aircraft refueling port for fuel filling. During the refueling process, a large amount of oil and gas escapes from the refueling port. If it cannot be diffused and ventilated in time, it is very easy to form a high concentration of oil vapor accumulation, posing a safety hazard. In addition, when refueling, the existing refueling gun is generally used to limit the refueling gun by engaging with the fuel tank port through a threaded fixing ring fixed on the side end of the oil outlet pipe. When the refueling pipe shakes or moves, it is easy to pull the refueling gun out of the fuel tank port, thereby causing fuel to spill outside, which not only wastes materials but also pollutes the environment. In addition, during the refueling process, the refueling staff is required to place the oil gun at the refueling port. When refueling at night, due to the limitation of light, the position of the fuel tank is even more unclear. If you are not careful, the aviation fuel may splash out and splash onto the staff, causing harm to the staff. Summary of the invention

[0016] The beneficial effects of the present invention are:

[0017] (1) The general aircraft refueling gun capable of automatically stopping described in the present invention can seal the gas in the fuel tank by means of a protective structure installed at the side end of the refueling gun body, thereby preventing a large amount of oil and gas from escaping from the refueling port. The refueling gun body can be conveniently fixed at the refueling hole of the fuel tank by means of a fixing structure, thereby preventing the refueling gun body from falling and causing fuel to scatter during refueling. The refueling gun body and the protective structure can be installed and connected by means of a positioning structure and a limiting structure. That is, when it is necessary to inject aviation fuel into the refueling gun body of the aircraft, the fixing seat is first installed at the side end of the oil outlet pipe at the side end of the refueling gun body, and the rubber ring is engaged with the oil filling hole of the fuel tank, thereby sealing the oil and gas in the fuel tank, thereby preventing the oil and gas in the fuel tank from escaping, thereby preventing air pollution and preventing the volatilization of fuel from affecting the use. The rubber block fixed in the rubber ring can better seal the oil filling hole, and then the top block is pressed by an external screwdriver, thereby driving the top block to slide in the fixed shaft, thereby driving the insertion rod to slide in the fixed shaft through the sliding connection of the rotating rod and the sliding groove. When the insertion rod slides to and After the slots are separated, the external screwdriver is rotated, so that the fixed shaft can be driven to rotate through the top block, and the turntable can be driven to rotate through the rotating shaft, so that the first interference block fixed on the turntable can be driven to rotate, and because the first interference block and the interference plate are in conflict, the interference plate can be driven to slide in the fixed seat, so that the fixed seat can be fixed to the oil filling pipe of the oil tank through the clamping rod fixed at the side end of the interference plate, and the second interference block can also be driven to rotate when the turntable rotates, and the clamping plate can be driven to slide in the fixed seat through the interference between the second interference block and the positioning block, so that the clamping plate can be fixed on the oil outlet The fixing ring and the clamping plate at the side end of the tube are engaged, which can facilitate the installation of the fixing seat on the oil outlet pipe at the side end of the fuel gun body. After the fuel is added, the reverse rotation of the top block can drive the fixed shaft to rotate, thereby driving the first resistance block and the second resistance block to rotate, so that the fixing seat can be removed from the oil filling pipe of the fuel tank, and the fixing seat can also be removed from the side end of the fuel gun body. The second spring can drive the top block to slide and reset in the fixed shaft, and the first spring fixed at the side end of the limit block can drive the clamping plate to slide and reset after the positioning block and the second resistance block are separated.

[0018] (2) The general aircraft fueling gun capable of automatic stop according to the present invention can illuminate the surrounding environment when injecting fuel at night through the lighting structure installed on the side end of the fueling gun body. The installation structure facilitates the limit fixation of the lighting structure.

After the first contact and the second contact are in contact, since the first contact is electrically connected to the lighting lamp, the second contact is electrically connected to the internal power supply, and the lighting lamp and the internal power supply are electrically connected, a circuit loop can be formed after the first contact and the second contact are in contact, thereby driving the lighting lamp to work and illuminate the surrounding area.

When lighting is not required, pressing the push block can drive the top plate to slide, thereby driving the sliding plate to slide.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0028] As Figures 1-6 shown, a general aircraft refueling gun capable of automatically stopping according to the present invention includes a refueling gun body 1. A protection structure 2 is installed on the side end of the refueling gun body 1. A fixing structure 3 is installed inside the protection structure 2. A positioning structure 4 is installed inside the protection structure 2. A limiting structure 5 is installed inside the protection structure 2. A lighting structure 6 is installed on the side end of the refueling gun body 1. An installation structure 7 is installed inside the lighting structure 6;

[0029] The protection structure 2 includes an oil outlet pipe 201. The oil outlet pipe 201 is installed on the side end of the refueling gun body 1. The side end of the oil outlet pipe 201 is detachably connected to a fixed seat 202. The side end of the fixed seat 202 is fixedly connected to a rubber ring 203. A rubber block 204 is installed inside the rubber ring 203. The fixed seat 202 is installed on the side end of the oil outlet pipe 201 on the side end of the refueling gun body 1. The rubber ring 203 is clamped with the fuel injection hole of the fuel tank, so as to be able to seal the oil and gas in the fuel tank. Therefore, it can prevent the oil and gas in the fuel tank from emitting, not only can prevent air pollution, but also can prevent the fuel from volatilizing and affecting the use. Through the rubber block 204 fixed in the rubber ring 203, the fuel injection hole can be better sealed.

[0030] Specifically, the fixing structure 3 includes a contact plate 301 which is slidably connected inside the fixing base 202. A clamping rod 302 is fixedly connected to the side end of the contact plate 301, and the clamping rod 302 is slidably connected to the rubber ring 203. A rotating shaft 303 is rotatably connected inside the fixing base 202, and a turntable 304 is fixedly connected to the side end of the rotating shaft 303. The turntable 304 is rotatably connected to the fixing base 202. A first contact block 305 is fixedly connected to the side end of the turntable 304, and the first contact block 305 contacts the contact plate 301. By driving the turntable 304 to rotate through the rotating shaft 303, the first contact block 305 fixed on the turntable 304 can be driven to rotate. Since the first contact block 305 contacts the contact plate 301, the contact plate 301 can be driven to slide inside the fixing base 202. Therefore, through the clamping rod 302 fixed to the side end of the contact plate 301, the fixing base 202 can be fixed on the fuel tank filling pipe.

[0031] Specifically, the positioning structure 4 includes a clamping plate 401 which is slidably connected inside the fixing base 202. A fixing ring 402 is fixedly connected to the side end of the oil outlet pipe 201, and the fixing ring 402 is engaged with the clamping plate 401. A positioning block 403 is fixedly connected to the side end of the clamping plate 401, and a second contact block 404 is fixedly connected to the side end of the turntable 304. The positioning block 403 contacts the second contact block 404. A limiting block 405 is fixedly connected to the side end of the clamping plate 401, and the limiting block 405 is slidably connected to the fixing base 202. A first spring 406 is fixedly connected between the limiting block 405 and the fixing base 202. When the turntable 304 rotates, it can also drive the second contact block 404 to rotate. By the second contact block 404 contacting the positioning block 403, the clamping plate 401 can be driven to slide inside the fixing base 202. Therefore, by the fixing ring 402 fixed to the side end of the oil outlet pipe 201 being engaged with the clamping plate 401, it is convenient to install the fixing base 202 on the oil outlet pipe 201 at the side end of the fuel dispenser body 1. After refueling, rotating the top block 502 in the reverse direction can drive the fixed shaft 501 to rotate, thereby driving the first contact block 305 and the second contact block 404 to rotate, so that the fixing base 202 can be removed from the fuel tank filling pipe, and the fixing base 202 can also be removed from the side end of the fuel dispenser body 1. Through the second spring 507, the top block 502 can be driven to slide and reset inside the fixed shaft 501. Through the first spring 406 fixed to the side end of the limiting block 405, after the positioning block 403 and the second contact block 404 are separated, the clamping plate 401 can be driven to slide and reset.

[0032] Specifically, the limiting structure 5 includes a fixed shaft 501. The side end of the fixed seat 202 is rotatably connected to the fixed shaft 501. A top block 502 is slidably connected inside the fixed shaft 501, and a plug rod 503 is slidably connected inside the fixed shaft 501. A slot 504 is provided inside the fixed seat 202, and the plug rod 503 is inserted into the slot 504. A second spring 507 is fixedly connected between the top block 502 and the fixed shaft 501. A rotating rod 505 is fixedly connected inside the top block 502. A sliding groove 506 is provided on the side end of the plug rod 503, and the rotating rod 505 is slidably connected to the sliding groove 506. By pressing the top block 502 with an external screwdriver, the top block 502 can be driven to slide inside the fixed shaft 501. Thus, through the sliding connection between the rotating rod 505 and the sliding groove 506, the plug rod 503 can be driven to slide inside the fixed shaft 501. When the plug rod 503 slides to be separated from the slot 504, rotate the external screwdriver. Thus, the fixed shaft 501 can be driven to rotate by the top block 502.

[0033] Specifically, the lighting structure 6 includes an insulating rod 601. The side end of the fuel dispenser body 1 is fixedly connected to the insulating rod 601. A sliding plate 602 is slidably connected inside the insulating rod 601. A pressing block 603 is fixedly connected to the top end of the sliding plate 602. A first contact 604 is fixedly connected to the bottom end of the sliding plate 602. A second contact 605 is fixedly connected inside the insulating rod 601. The first contact 604 abuts against the second contact 605. A third spring 606 is fixedly connected between the sliding plate 602 and the insulating rod 601. A lighting lamp 607 is fixedly connected to the side end of the fuel dispenser body 1. When lighting is required during fuel injection at night, when grasping the insulating rod 601, the pressing block 603 can be pressed downward to slide, thereby driving the sliding plate 602 to slide downward. When the first contact 604 abuts against the second contact 605, since the first contact 604 is electrically connected to the lighting lamp 607, the second contact 605 is electrically connected to the internal power supply, and the lighting lamp 607 is electrically connected to the internal power supply, a circuit loop can be formed after the first contact 604 abuts against the second contact 605. Thus, the lighting lamp 607 can be driven to work to illuminate the surroundings.

[0034] Specifically, the installation structure 7 includes a fixing rod 701. The bottom end of the sliding plate 602 is fixedly connected to the fixing rod 701. A fixing block 702 is fixedly connected inside the insulating rod 601. The fixing rod 701 is inserted into the fixing block 702. The bottom end of the sliding plate 602 is fixedly connected to a top plate 703. The top plate 703 is slidably connected to the insulating rod 601. The bottom end of the top plate 703 is fixedly connected to a pushing block 704. By engaging the fixing rod 701 with the fixing block 702, the sliding plate 602 can be fixed, thereby preventing the sliding plate 602 from resetting and affecting lighting. When lighting is not required, pressing the pushing block 704 can drive the top plate 703 to slide, thereby driving the sliding plate 602 to slide. After the fixing rod 701 and the fixing block 702 are separated, the elastic force of the third spring 606 can drive the sliding plate 602 to slide back to its original position.

[0035] When the present invention is in use, when it is necessary to inject aviation fuel into the fuel gun body 1 of the aircraft, first install the fixed seat 202 at the side end of the oil outlet pipe 201 on the side end of the fuel gun body 1, and engage it with the fuel injection hole of the fuel tank through the rubber ring 203, so as to seal the oil and gas in the fuel tank. Therefore, it can prevent the emission of oil and gas in the fuel tank, not only prevent air pollution, but also prevent the evaporation of fuel from affecting the use. Through the rubber block 204 fixed in the rubber ring 203, better sealing treatment can be carried out at the fuel injection hole. Then, press the top block 502 with an external screwdriver, so that the top block 502 can slide in the fixed shaft 501. Thus, through the sliding connection between the rotating rod 505 and the chute 506, the plug rod 503 can be driven to slide in the fixed shaft 501. When the plug rod 503 slides to be separated from the slot 504, rotate the external screwdriver, so that the fixed shaft 501 can be driven to rotate by the top block 502. Therefore, the turntable 304 can be driven to rotate by the rotating shaft 303, and the first contact block 305 fixed on the turntable 304 can be driven to rotate. Since the first contact block 305 abuts against the contact plate 301, the contact plate 301 can be driven to slide in the fixed seat 202. Therefore, through the clamping rod 302 fixed on the side end of the contact plate 301, the fixed seat 202 can be fixed on the fuel tank injection pipe. When the turntable 304 rotates, the second contact block 404 can also be driven to rotate. By the second contact block 404 abutting against the positioning block 403, the clamping plate 401 can be driven to slide in the fixed seat 202. Therefore, through the fixed ring 402 fixed on the side end of the oil outlet pipe 201 and the clamping plate 401 being engaged, it is convenient to install the fixed seat 202 on the oil outlet pipe 201 at the side end of the fuel gun body 1. After refueling, rotating the top block 502 in the reverse direction can drive the fixed shaft 501 to rotate, so that the first contact block 305 and the second contact block 404 can be driven to rotate, so that the fixed seat 202 can be removed from the fuel tank injection pipe, and the fixed seat 202 can also be removed from the side end of the fuel gun body 1. Through the second spring 507, the top block 502 can be driven to slide and reset in the fixed shaft 501. Through the first spring 406 fixed on the side end of the limit block 405, after the positioning block 403 and the second contact block 404 are separated, the clamping plate 401 can be driven to slide and reset. When it is necessary to illuminate when injecting fuel at night, when grasping the insulating rod 601, the pressing block 603 can be pressed downward to slide, so that the slide plate 602 can be driven to slide downward. When the first contact 604 abuts against the second contact 605, since the first contact 604 is electrically connected to the illuminating lamp 607, the second contact 605 is electrically connected to the internal power supply, and the illuminating lamp 607 is electrically connected to the internal power supply, a circuit loop can be formed after the first contact 604 abuts against the second contact 605, so that the illuminating lamp 607 can be driven to work to illuminate the surrounding area. Through the engagement of the fixing rod 701 and the fixing block 702, the slide plate 602 can be fixed, so as to prevent the slide plate 602 from resetting and affecting the illumination. When illumination is not required,Pressing the push block 704 can drive the top plate 703 to slide, thereby driving the slide plate 602 to slide. After the fixed rod 701 and the fixed block 702 are separated, the elastic force of the third spring 606 can drive the slide plate 602 to slide back to its original position.
