Embodiment Construction
[0016] Further illustrate the present invention below in conjunction with accompanying drawing.
[0017] like figure 1 , 2 As shown, the present invention includes a fixing bolt 8 with a central through hole, an inner end for connecting with a fuel engine, and an oil pipe joint 3 sleeved on the fixing bolt 8 . The oil pipe joint 3 has a joint nozzle 3-1, and the side wall of the fixing bolt 8 is provided with an oil hole 8-2 for connecting the joint nozzle 3-1 and the central through hole.
[0018] The present invention also includes a connection terminal 6 that is internally packaged with a connection section between a wire 7 and the heating element 1, the wire 7 is drawn out from the connection terminal 6 for connecting a power supply, and the heating element 1 is inward from the connection terminal 6 Lead out and pass through the central through hole of the fixing bolt 8 for heating the fuel. The connecting terminal 6 is inserted into the central through hole of the fix...

The invention provides a connecting device of an oil tube and a heating element. The connecting device comprises a fixed bolt (8) with a central through hole, an oil tube joint (3) sleeved on the fixed bolt (8), and a wiring terminal (6) internally provided with a connecting section of a lead (7) and a heating element (1) in an encapsulation way. The wiring terminal (6) is inserted into the central through hole of the fixed bolt (8) from an external port of the fixed bolt (8); and a matching section of the wiring terminal (6) and the central through hole of the fixed bolt (8) is gradually thinned from outside to inside. A closing nut (5) with the external end blocked on the wiring terminal (6) is in threaded match with the external end of the fixed bolt (8); and an internal end sealing ring (2) and an external sealing ring (4) which are respectively arranged against the internal end surface and the external end surface of the oil tube joint (3), are arranged on the fixed bolt (8). According to the connecting device, the wiring terminal and the fixed bolt can be mounted and dismounted by simply being screwed; and the operation in assembling and dismounting is relatively convenient and simple to carry out.
Description
[0001] [0002] technical field [0003] The invention relates to a connection device for an oil pipe and a heating element. It is mainly used to connect the oil inlet and outlet pipes of the fuel engine and is also used to connect the heating element of the fuel engine. [0004] Background technique [0005] The fuel heating element of the fuel engine is generally external, that is, the heating element is arranged on the outer wall of the heated container (such as the engine, oil pipe, oil cup, etc.), and the internal fuel is heated through the heat conduction of the container wall. The main disadvantage is the low heat transfer efficiency. It consumes a lot of energy and affects the normal operation of the battery. [0006] The Chinese invention patent with the notification number CN201129581 discloses "a fuel pipe fixing connector", which can not only allow the power wire to pass through, but also effectively seal the oil pipe connection, and realize the purpose of hea...
