Detailed Description
Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, which is a good sealing oil delivery joint.
Wherein, the hose 24 is connected with the joint 10 through the hose connector 20, thereby increasing tightness. The apertured nut 23 is screwed onto the attachment ring 14 so that the second sealing ring 22 is compressed by the apertured nut 23 and the first sealing ring 21 is inserted into the first sealing groove 15, whereby the connection between the hose 24 and the fitting 10 is very tight and does not loosen.
The application provides an oil delivery joint with good sealing performance, which comprises a joint 10 made of aluminum alloy and a hose 24 arranged on the joint 10; the joint 10 is a cylinder with a hollow inner part; the outer surface of the left end of the joint 10 is cut to form a plug-in joint 11; the outer surface of the joint 10 is provided with anti-drop rings 12, hexagonal nuts 13 and threaded connecting rings 14 at intervals from left to right; a first sealing groove 15 is concavely arranged on the right end face of the joint 10; the hose 24 is extended with a hose connector 20; the hose connector 20 is provided with a first sealing ring 21 and a second sealing ring 22; the second seal ring 22 is vertically connected to the first seal ring 21; a screw cap with a hole 23 is sleeved on the hose connector 20; a holed nut 23 is screwed to the coupling ring 14, said first sealing ring 21 being inserted in the first sealing groove 15. The hollow structure inside the joint 10 is used for oil transportation. Oil enters from the hose 24 and then through the fitting 10 into the oil tank. Connection of the hose 24 on the fitting 10: the hose 24 is inserted through the hole of the perforated nut 23, and the perforated nut 23 is screwed to the connection ring 14, so that the first sealing ring 21 is inserted into the first sealing groove 15, and the second sealing ring 22 is pressed against the right end surface of the joint 10 by the inner wall of the perforated nut 23, and thus the joint 10 and the hose 24 are connected with good sealing performance and are not loosened. The second sealing ring 22 and the first sealing ring 21 are vertically connected together, and the combination of the two increases the leakage path, so the sealing performance is better. The anti-slip ring 12 can prevent the joint 10 from slipping out of the oil tank, and the hexagonal nut 13 blocks the oil tank opening during oil filling, so that the safety can be improved. The hexagonal nut 13 also facilitates the threading of the apertured nut 23 onto the attachment ring 14. The clamping block 30 with the elastic block is generally arranged in the oil tank, and the anti-drop ring 12 can be clamped on the clamping block 30 when oil is filled, so that the anti-drop ring is not easy to slide out of the oil tank. When needing to be noticed, the clamping block 30 can not completely and tightly clamp the anti-drop ring 12, and a part of gap is reserved between the anti-drop ring 12 and the clamping block 30 for balancing the internal and external pressure of the oil tank. The hose 24 is a flexible tube that can withstand deformation. The hose connector 20 and the hose 24 are of one-piece construction.
Further, the outer diameter of the plug 11 gradually increases from left to right. This configuration facilitates smooth transition of force when the fitting 10 is inserted into the fuel tank, while facilitating insertion of the fitting 10 into the fuel tank.
Further, a separation preventing groove 18 is formed between the separation preventing ring 12 and the hexagonal nut 13. The snap-in block 30 in the tank is snapped into the anti-slip groove 18 to prevent the anti-slip ring 12 from slipping out of the tank.
Preferably, the joint between the anti-drop ring 12 and the joint 10 is provided with an arc-shaped transition surface, which facilitates smooth force transition when inserting or extracting the fuel tank, and also facilitates easier processing of the joint 10.
Further, a second sealing groove 16 is formed between the hexagonal nut 13 and the connection ring 14, and a third sealing ring 17 is disposed in the second sealing groove 16. After the hexagonal nut 13 is screwed, the space between the hexagonal nut 13 and the connection ring 14 is sealed by the third sealing ring 17, so that the sealing performance is further improved.
Preferably, the first sealing ring 21, the second sealing ring 22 and the third sealing ring 17 are rubber sealing rings or plastic sealing rings.
Preferably, the outer surface of the hose 24 has a metal braid to prevent the hose 24 from being damaged and bitten by a mouse.
In summary, the design of the present invention is focused on the connection between the hose 24 and the connector 10 via the hose connector 20. The apertured nut 23 is screwed onto the attachment ring 14 so that the second sealing ring 22 is compressed by the apertured nut 23 while the first sealing ring 21 is inserted into the first sealing groove 15, whereby the connection between the hose 24 and the fitting 10 is very tight and does not loosen. After the hexagonal nut 13 is screwed, the space between the hexagonal nut 13 and the connection ring 14 is sealed by the third sealing ring 17, so that the sealing performance is further improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
