Description

Well lid opening device for airplane refueling bolt well

Technical Field

The utility model relates to an aircraft fuel filler bolt well technical field specifically is an aircraft fuel filler bolt well lid opening device.

Background

Along with the development of science and technology, the design of the well cover of the oil filling bolt well in the airport apron is more and more environment-friendly and safe. The fueler well lid is very obvious with traditional all kinds of well lids difference, at first the well lid periphery is equipped with the sealing washer, makes well lid and well body combine closely, not only can prevent in the well that the long-pending oil that volatilizees the polluted air also can prevent rainwater, debris etc. from getting into in the well, secondly the well lid has self-locking function (well lid is covered the back and is clockwise rotated, outstanding little cylinder slips into well body track under the well lid) and prevents that the well lid from breaking away from the well body because of external factor, two ear holes on the well lid terminal surface are used for the bare-handed use of uncapping of staff. Reason based on above function leads to the gas pin well lid very hard and consuming time when opening, still causes staff's waist strain easily, then urgently needed an appurtenance to assist the staff to carry out the well lid and open in the face of above problem to reduce intensity of labour, improve work efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that still causes staff's waist strain easily when having the gas pin well lid to open among the prior art very hard and consuming time, and the aircraft gas pin well lid opening device who provides.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an aircraft fuel hydrant well lid opening device, includes and rotates the handle and rotate the handle pole, the equal slidable mounting in outer wall both sides of rotating the handle pole has the revolute pair, the below of revolute pair rotates and links to each other there is the transmission landing leg, the inner wall below rigid coupling of transmission landing leg has the right angle parallel hook, the inboard center of outer wall of transmission landing leg is provided with reset spring, reset spring's both sides end all links to each other with the transmission landing leg is fixed.

Preferably, the left side and the right side of the outer wall of the rotating handle rod are sleeved with the rotating handles.

Preferably, the upper parts of the outer ends of the outer walls of the transmission supporting legs are fixedly connected with transmission supporting leg handles.

Preferably, the rotating grip and the surface of the handle of the transmission leg are sleeved with rubber layers.

The utility model provides a pair of aircraft fuel hydrant well lid opening device, beneficial effect lies in:

through the handle, the landing leg handle, the transmission landing leg, cooperation between reset spring and the right angle parallel hook, when opening device uses, the rotation handle is held to both hands, and drive transmission landing leg handle with the finger and make the transmission landing leg open, put into the terminal right angle parallel hook of transmission landing leg respectively in the well lid both sides ear hole of fuel hydrant again, then the transmission landing leg handle of transmission landing leg is loosened respectively to both hands, reset spring then drives the terminal right angle parallel hook of both sides transmission landing leg and is fixed in well lid both sides ear hole to the relative motion, mention earlier with both hands at last and rotate the handle, reuse both hands applys a moment of couple to rotating the handle, upwards mention behind the rotation well lid, accomplish the well lid and open, it is very hard and consuming time when effectually having avoided the fuel hydrant well lid to open, still cause the problem of staff's waist strain easily.

Drawings

Fig. 1 is a schematic view of the structure of the present invention;

fig. 2 is a left side view structure diagram of the present invention;

fig. 3 is a schematic top view of the present invention.

In the figure: 1. the handle comprises a rotary handle, 2 a revolute pair, 3 a rotary handle rod, 4 a return spring, 5 a transmission supporting leg handle, 6 a transmission supporting leg, 7 and a right-angle flat hook.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to figures 1-3: in the embodiment, the device for opening the well lid of the airplane refueling bolt well comprises a rotating handle 1 and a rotating handle rod 3, wherein two sides of the outer wall of the rotating handle rod 3 are both provided with a revolute pair 2 in a sliding manner, a transmission leg 6 is rotatably connected to the lower part of the revolute pair 2, a right-angle flat hook 7 is fixedly connected to the lower part of the inner wall of the transmission leg 6, a reset spring 4 is arranged at the center of the inner side of the outer wall of the transmission leg 6, the transmission leg 6 with the handle is connected with the rotating handle 1 through the revolute pair 2 and can rotate freely, the surfaces of the rotating handle 1 and the transmission leg handle 5 are sleeved with rubber layers, the skin of a hand is prevented from being abraded during operation, two ends of the reset spring 4 are respectively fixed at the middle position of the two transmission legs 6 with the handle, the tail ends of two sides of the reset spring 4 are fixedly connected with the transmission leg 6, the left side and the right side of the outer wall of the rotating handle rod 3 are sleeved with the rotating handle 1, the transmission leg 6 is fixedly connected with the transmission leg handle 5, the outer wall of the rotating handle 2, the rotating handle 3, the reset spring 4, the right-angle flat hook 7 can be made of iron, copper, or other transmission legs, the transmission legs can be made of a transmission legs, or made of a hard aluminum alloy flat hook 3, 2136;

through handle 1, landing leg handle 5, transmission landing leg 6, cooperation between reset spring 4 and the right angle parallel hook 7, when opening device uses, rotation handle 1 is held to both hands, and drive transmission landing leg handle 5 with the finger and make transmission landing leg 6 open, put into the terminal right angle parallel hook 7 of transmission landing leg 6 respectively in the well lid both sides ear hole of fuel hydrant, then both hands loosen the transmission landing leg handle 5 of transmission landing leg 6 respectively, reset spring 4 then drives the terminal right angle parallel hook 7 of both sides transmission landing leg and is fixed in well lid both sides ear hole to the relative motion, lift earlier with both hands at last and rotate handle 1, reuse both hands exert a moment of couple to rotating handle 1, upwards mention behind the well lid rotating, accomplish the well lid and open, the effectual very hard and consuming time when having avoided the fuel hydrant well lid to open, still cause the problem of staff's waist strain easily.
