DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-5 As shown in the figure, a kind of oil gun integrated high-efficiency oil gas recovery gas collecting cover device, including connecting cover 1 and fixed sleeve 2, fixed sleeve 2 is installed on the outside of connecting cover 1, and the top of fixed sleeve 2 is fixedly connected with connecting ring 3.

[0026] Fixed sleeve 2 is made of rubber material, which can be deformed according to the oil tank filler of different vehicles, and connecting ring 3 can be connected to the oil gun.

[0027] Mounting ring 4 is fixed to the inner wall of connecting ring 3, and the outside of connecting ring 3 is provided with first connecting block 5.

[0028] Mounting ring 4 is made of rubber material, and the cooperation of mounting ring 4 and fixed groove 15 can facilitate the extrusion of excess air in fixed groove 15 when first connecting block 5 and second connecting block 6 are closed, so that the air pressure in the area is lower than the atmospheric pressure of the surrounding environment, forming negative pressure, thereby improving the stability of the connection after installation.

[0029] Second connecting block 6 is rotatably connected to the outside of first connecting block 5.

[0030] The cooperation of second connecting block 6 and first connecting block 5 can facilitate the fixation of connecting ring 3 by cooperating with bolt 7 and limiting nut 18, so as to prevent connecting cover 1 from falling off the surface of the oil gun after installation.

[0031] Bolt 7 is bolted to the inner wall of first connecting block 5 and second connecting block 6 respectively.

[0032] Bolt 7 can facilitate the fixation of first connecting block 5 and second connecting block 6, thereby facilitating the installation and disassembly of connecting cover 1.

[0033] The bottom of the connecting cover 1 is fixedly connected with a limiting frame 8, and the inner wall of the limiting frame 8 is provided with a mounting hole 9.

[0034] The limiting frame 8 can assist the limiting rod 10 to slide, and the inner wall of the limiting frame 8 is provided with the mounting hole 9, so that the sealing groove 14 can be deformed when contacting the oil inlet of the vehicle oil tank, thereby preventing the protruding nut from damaging the paint surface of the vehicle.

[0035] The inner wall of the limiting frame 8 is slidably connected with the limiting rod 10, and the outer side of the fixed sleeve 2 is provided with a limiting groove 11 for cooperating with the limiting rod 10.

[0036] The limiting rod 10 is used in cooperation with the limiting groove 11, so that the fixed sleeve 2 and the bottom of the connecting cover 1 can be connected, thereby preventing the fixed sleeve 2 from frequently falling off from the outer side of the connecting cover 1.

[0037] The outer side of the limiting rod 10 is provided with a limiting spring 12, the outer side of the limiting rod 10 is fixedly connected with a limiting piece 13 for limiting the limiting spring 12, and the outer side of the limiting piece 13 is fixedly connected with one end of the limiting spring 12.

[0038] When the fixed sleeve 2 needs to be disassembled, the limiting rod 10 is first pulled, at this time, the limiting rod 10 drives the limiting piece 13 to compress the limiting spring 12, and at the same time, the limiting rod 10 is separated from the limiting groove 11, at this time, the fixed sleeve 2 can be disassembled, when installing, the fixed sleeve 2 is sleeved on the outer side of the connecting cover 1, then the limiting rod 10 is loosened, at this time, the limiting spring 12 rebounds to force the limiting rod 10 to move horizontally, thereby the limiting rod 10 is clamped with the limiting groove 11, so that the installation of the fixed sleeve 2 is completed.

[0039] The bottom of the connecting cover 1 is provided with a sealing groove 14 for preventing oil gas from leaking when refueling.

[0040] The sealing groove 14 is made of rubber material, when contacting the vehicle surface, due to the mutual extrusion of the oil inlet of the oil tank and the sealing groove 14, the air inside the groove is forced out, forming a negative pressure area, due to the action of the external atmospheric pressure, the rubber grooving part will be tightly adsorbed on the vehicle surface, thereby preventing oil gas from leaking during refueling.

[0041] The inner wall of the mounting ring 4 is provided with a fixed groove 15, and the inner wall of the connecting ring 3 is provided with a mounting groove 16.

[0042] The fixed groove 15 can provide a negative pressure area, and the mounting groove 16 can prevent the connecting ring 3 from being extruded and deformed to expose a gap when the first connecting block 5 and the second connecting block 6 are closed, thereby reducing the stability of the connection.

[0043] The inner wall of the first connecting block 5 is rotationally connected with a supporting rod 17, and the outer side of the supporting rod 17 is rotationally connected with the inner wall of the second connecting block 6, and the outer side of the bolt 7 is threadedly connected with a limiting nut 18.

[0044] The supporting rod 17 can assist the first connecting block 5 and the second connecting block 6 to rotate, and the limiting nut 18 is used in cooperation with the bolt 7, so that the first connecting block 5 and the second connecting block 6 can be conveniently limited, thereby improving the stability when the connecting cover 1 is connected with the oil gun.

[0045] Working principle: firstly, the rotating limiting nut 18 releases the bolt 7, then the device is inserted into the outer side of the oil gun through the middle slot, then the first connecting block 5 and the second connecting block 6 limit the connecting ring 3, then the rotating limiting nut 18 limits the bolt 7, so that the first connecting block 5 and the second connecting block 6 are limited, and then the device is fixed to the outer side of the oil gun, when the fixed sleeve 2 needs to be disassembled, firstly, the limiting rod 10 is pulled, at this time, the limiting rod 10 drives the limiting piece 13 to compress the limiting spring 12, and at the same time, the limiting rod 10 is separated from the limiting slot 11, at this time, the fixed sleeve 2 can be disassembled, when the fixed sleeve 2 is installed, firstly, the fixed sleeve 2 is sleeved on the outer side of the connecting cover 1, then the limiting rod 10 is loosened, at this time, the limiting spring 12 rebounds to force the limiting rod 10 to move horizontally, so that the limiting rod 10 is clamped with the limiting slot 11, thereby completing the installation of the fixed sleeve 2, and then the oil gun can work on the oil tank filler.
