Abstract
The utility model discloses a device for connecting an oil pipe with a heating element. The device comprises a fixing bolt (8), an oil pipe joint (3) and a wiring terminal (6), wherein the fixing bolt is provided with a center through hole; the oil pipe joint (3) is fixed on the fixing bolt (8); and a connecting section, which is arranged between a lead wire (7) and the heating element (1), is packed in the wiring terminal (6). The wiring terminal (6) is inserted into the center through hole of the fixing bolt (8) from the external orifice of the fixing bolt (8), and the matching section of the wiring terminal (6) with the center through hole of the fixing bolt (8) is thinner gradually from outside to inside. A closed nut (5) of which an outer end is clamped on the wiring terminal (6) is in threaded fit with the outer end part of the fixing bolt (8); and the fixing bolt (8) is further provided with an inner-end sealing ring (2) and an outer-end sealing ring (4) which are respectively butted against to the inner end surface and the outer end surface of the oil pipe joint (3). The assembly/disassembly between the wiring terminal and the fixing bolt can be realized through a simple screwing operation, so that the assembly/disassembly operation is more convenient and fast.
Description
Technical field
The utility model relates to a kind of oil pipe and heating element connection set.The heating element that is mainly used in connecting the turnover oil pipe of fuel engine and is used for connecting simultaneously fuel engine.
Background technique
The fuel Heating element of fuel engine is generally external, being about to heating element is arranged on the outer wall that is heated container (such as motor, oil pipe, lubricating cup etc.), heat conduction by container wall is implemented contactless heating to inner fuel oil, and the major defect of this mode is that heat transfer efficiency is low.Power consumption is large, affects the normal operation of storage battery.
Notification number is that the Chinese utility model patent of CN201129581 discloses " a kind of oil passageway fixed connect member ", can allow power lead to pass through, can effectively seal the oil pipe connection place again, realized the purpose that in oil pipe or fuel tank, diesel oil heated, having solved is the built-in problem of electrical heating elements, has improved heat conduction efficiency.But the oil passageway fixed connect member complicated structure of this structure, assembly manipulation is loaded down with trivial details.
The model utility content
Technical problem to be solved in the utility model is: by a kind of oil pipe and heating element connection set are provided, can the cross-under wire, on the basis that meets the demands of heating element and sealing, have more succinct structure, and make assembling simpler.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme.
A kind of oil pipe and heating element connection set is characterized in that: it comprises with the fixing bolt of central through bore and is enclosed within oil connection on this fixing bolt, offers on the sidewall of fixing bolt for the oilhole that is communicated with oil connection and described central through bore; Comprise that also inside is packaged with the tenminal block of the linkage section between wire and the heating element, among tenminal block is inserted into the central through bore of fixing bolt from the external port of fixing bolt, tenminal block is tapered from outside to inside with the section of the cooperation outer wall of the central through bore of fixing bolt, and the central through bore of fixing bolt also is tapered from outside to inside with the tenminal block section of cooperation inwall; The outer end is stuck in sealing nut on the tenminal block and the outer end screw-thread fit of fixing bolt; The inner seal ring and the outer end seal ring that lean against respectively the inside and outside end face of oil connection also are installed on fixing bolt.
Also be fixedly installed the spanner cap between sealing nut and oil connection on the fixing bolt; Described outer end seal ring is between this spanner cap and described oil connection.
Good effect of the present utility model is: the first, wire and heating element are imported into through tenminal block among the central through bore of fixing bolt, and heating element is inwardly derived through described central through bore, enter the fuel Heating container.Thereby realized the built-in layout of heating element, had higher heat conduction efficiency, and reduced energy consumption.The second, because the section of cooperation of tenminal block and the central through bore of fixing bolt with tapering, along with sealing tightening of nut, has realized closely cooperating between the central through bore wall of tenminal block and fixing bolt, has better sealing effect.Three, by being set, interior exterior seal ring guaranteed sealing to exterior edge face in the oil connection.The more important thing is that four, by sealing nut and spanner cap are screwed the dismounting that can realize between tenminal block and the fixing bolt in opposite directions, assembling and disassembling section are more convenient.
Description of drawings
Fig. 1 is overall structure schematic representation of the present utility model.
Fig. 2 is the structural representation of the utility model fixing bolt.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, the utility model comprises with central through bore, inner be used for the fixing bolt 8 that is connected with fuel engine and be enclosed within oil connection 3 on this fixing bolt 8.Described oil connection 3 offers on the sidewall of fixing bolt 8 for the oilhole 8-2 that is communicated with joint mouth 3-1 and described central through bore with joint mouth 3-1.
The utility model comprises that also inside is packaged with the tenminal block 6 of the linkage section between wire 7 and the heating element 1, described wire 7 is outwards drawn for connecting power supply from tenminal block 6, and the central through bore that fixing bolt 8 was inwardly drawn and passed to described heating element 1 from tenminal block 6 is used for fuel oil is heated.Among tenminal block 6 is inserted into the central through bore of fixing bolt 8 from the external port of fixing bolt 8, the section of the cooperation outer wall of tenminal block 6 and the central through bore of fixing bolt 8, namely the outer wall of the tenminal block 6 in this cooperation segment limit is tapered from outside to inside, correspondingly, the central through bore of fixing bolt 8 and tenminal block 6 section of cooperation inwalls, namely the inwall of the central through bore of the fixing bolt 8 in this cooperation segment limit also is tapered from outside to inside.The outer end is stuck in the outer end screw-thread fit of sealing nut 5 and fixing bolt 8 on the annular boss 5-1 of tenminal block 6.Sealing nut 5 drives the central through bore that tenminal block 6 inserts fixing bolt 8 gradually when being tightened, and because tenminal block 6 is designed with tapering with the section of cooperation of the central through bore of fixing bolt 8, along with tightening of sealing nut 5, realized closely cooperating between the central through bore wall of tenminal block 6 and fixing bolt 8, played effective seal action.
The purpose of described encapsulation (such as encapsulating encapsulation) is that the linkage section between wire 7 and the heating element 1 (being joint part) is fixed in tenminal block 6 inside, and plays sealing process and outwards flow out with the fuel oil in the central through bore of prevention fixing bolt 8.
In order to realize the sealing at oil connection 3 inside and outside two ends, the inner seal ring 2 and the outer end seal ring 4 that lean against respectively oil connection 3 inside and outside end faces are installed also on fixing bolt 8.
Also be fixedly installed the spanner cap 8-1 between sealing nut 5 and oil connection 3 on the fixing bolt 8, as shown in Figure 2.The effect of this spanner cap 8-1 have two: the first, be used for blocking from the outer end outer end seal ring 4; The second, during charge and discharge operations as the engaging member of spanner.
