DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 5 and Figure 6 The embodiment of the present invention provides a device for heating fuel through a heating plate in front of a fuel rail, comprising a hollow plate 1, an oil delivery pipe 5 provided on the right side of the hollow plate 1, a plurality of fuel nozzles 6 connected to the bottom of the oil delivery pipe 5, a heating mechanism 2 provided on the inner side of the hollow plate 1, the heating mechanism 2 being used to heat the oil, a disassembly mechanism 3 provided on the outer side of the hollow plate 1, the disassembly mechanism 3 being used to facilitate maintenance of the device, and a conveying mechanism 4 provided on the inner side of the oil delivery pipe 5, the conveying mechanism 4 being used to convey the oil;

[0032] The heating mechanism 2 includes a double-headed spring rod 21, and the two double-headed spring rods 21 are respectively fixedly connected to the front and rear sides of the outside of the hollow plate 1. The left and right sides of the double-headed spring rod 21 are fixedly connected with a U-shaped block 22. The elastic potential energy of the double-headed spring rod 21 itself can push the U-shaped block 22 to move. The inner side of the U-shaped block 22 is rotatably connected to the telescopic plate 23, and the outer side of the telescopic plate 23 is rotatably connected to the top cover 24. The movement of the U-shaped block 22 can move the telescopic plate 23 to push the top cover 24 to move. The front and rear sides of the bottom of the top cover 24 are fixedly connected to the connecting frame 25, and the outer side of the connecting frame 25 is slidably connected to the heating rod 26. The inner bottom of the hollow plate 1 is fixedly connected with a heating block 27. Starting the heating block 27 can heat the heating rod 26. An operating component 28 is provided on the outer side of the U-shaped block 22, and a positioning component 29 is provided on the top of the hollow plate 1;

[0033] Specifically, the operator presses the U-shaped blocks 22 on both sides to cause them to move, thereby driving the double-headed spring rod 21 to contract. As the U-shaped blocks 22 move, the telescopic plate 23 begins to rotate under the action of the force, and the rotation of the telescopic plate 23 further pushes the top cover 24 and the connecting frame 25 to move upward. In this process, the heating rod 26 originally located on the outside of the heating block 27 is moved out. The operator can then pull the heating rod 26 out of the connecting frame 25 along the sliding direction, so that the heating rods 26 of different densities can be replaced according to actual needs. After the replacement is completed, the top cover 24 is reclosed on the top of the hollow plate 1, and the heating block 27 is started. The heat generated by the heating block 27 is transferred to the heating rod 26, and the oil can be heated.

[0034] Reference Figure 2 、 Figure 4 and Figure 7 The disassembly and assembly mechanism 3 includes an oil outlet 31, which is connected to the right side of the hollow plate 1. The middle part of the left side of the oil delivery pipe 5 is connected to a connecting cover 32. The connecting cover 32 can improve the sealing effect of the oil outlet 31. A plurality of positioning blocks 33 are fixedly connected to the outer side of the connecting cover 32. A rotating ring 34 is rotatably connected to the outer left side of the oil delivery pipe 5. A plurality of clamping plates 35 are fixedly connected to the outer side of the rotating ring 34. The clamping plates 35 are engaged with the positioning blocks 33. The clamping of the clamping plates 35 by the positioning blocks 33 can fix the oil outlet 31 and the connecting cover 32. A clamping block 36 is rotatably connected to the top left side of the oil delivery pipe 5. The clamping block 36 is engaged with the rotating ring 34. The engagement of the clamping block 36 with the rotating ring 34 can fix the rotation position and angle of the rotating ring 34. A sealing component 37 is provided on the left side of the hollow plate 1, and a penetrating component 38 is provided on the outer side of the top cover 24.

[0035] Specifically, the oil can be smoothly discharged into the oil delivery pipe 5 through the oil outlet 31, and the setting of the connecting cover 32 effectively improves the sealing performance of the oil outlet 31 to prevent oil leakage. When the hollow plate 1 needs to be dismantled and maintained, the operator only needs to rotate the clamping block 36 to release the clamping state with the rotating ring 34, and then rotate the rotating ring 34. The rotation of the rotating ring 34 will push the clamping plate 35 on it to move, and the clamping plate 35 will be released from the positioning block 33 after movement. In this way, the disassembly or fixing operation between the oil outlet 31 and the connecting cover 32 can be completed quickly and conveniently.

[0036] Reference Figure 4 、 Figure 7 and Figure 8 The conveying mechanism 4 includes a hollow cover 41 and a belt 43. The hollow cover 41 is connected to the left side of the top of the oil pipeline 5. The left and right sides of the bottom of the hollow cover 41 are rotatably connected to rotating wheels 42. The two rotating wheels 42 are connected by belts 43. The belts 43 can improve the stability and synchronization of the rotation of the rotating wheels 42. The bottom of the left rotating wheel 42 passes through the oil pipeline 5 and is fixedly connected to a bevel gear 411. When the rotating wheel 42 rotates, it drives the bevel gear 411 to rotate. The left side of the inside of the oil pipeline 5 is fixedly connected to a paddle 47, and the outer side of the paddle 47 is fixedly connected to a conical gear ring 41. 0, the conical gear ring 410 is meshed with the conical gear 411, and the right side of the paddle 47 is fixedly connected to the auger 48. The paddle 47 will circulate with the flow of oil and simultaneously drive the conical gear ring 410 and the auger 48 to rotate. The top of the hollow cover 41 is fixedly connected to the mounting block 44. The right side of the mounting block 44 is rotatably connected to the threaded rod 45. The outer side of the threaded rod 45 is threadedly connected to the threaded block 46. The threaded block 46 is rotatably connected to the right rotating wheel 42. Rotating the threaded rod 45 will push the threaded block 46 and the right rotating wheel 42 to move. A protective component 49 is provided on the outer side of the oil pipeline 5;

[0037] Specifically, when the oil flows in the pipeline, it will generate a driving force on the paddle 47 and the auger 48, causing them to start rotating. The rotation of the auger 48 can significantly improve the oil transportation effect and ensure that the oil flows more smoothly. At the same time, the rotation of the paddle 47 will also drive the bevel gear ring 410 to rotate. When the bevel gear ring 410 rotates, it drives the bevel gear 411 to rotate together through the meshing action with the bevel gear 411. After the bevel gear 411 rotates, with the help of the belt 43, the rotating wheels 42 on both sides will rotate synchronously. At this time, the operator rotates the threaded rod 45 along the mounting block 44. The rotation of the threaded rod 45 will drive the threaded block 46 and the rotating wheel 42 on the right to move. In this way, the tightness of the belt 43 can be adjusted, thereby controlling the rotation speed of the auger 48.

[0038] Reference Figure 2 、 Figure 3 and Figure 6The operating assembly 28 includes a handle 282, and a plurality of handles 282 are respectively fixedly connected to the outer side of the U-shaped block 22. The outer side of the handle 282 is fixedly connected to the connecting block 281. By pushing the handle 282 on the connecting block 281, it is easy to push and operate the U-shaped block 22 to move; the positioning assembly 29 includes an insertion rod 291, and a plurality of insertion rods 291 are respectively fixedly connected to the bottom of the top cover 24. Slots 292 are provided around the top of the hollow plate 1. The insertion rods 291 are engaged with the slots 292. The engagement of the insertion rods 291 with the slots 292 can improve the sealing of the top cover 24 when it is closed.

[0039] Specifically, by holding the handle 282 on the connecting block 281, it is easy to operate and push the U-shaped block 22 to move. When the top cover 24 and the hollow plate 1 are closed, the sealing of the top cover 24 when closed can be improved by engaging the insertion rod 291 with the slot 292.

[0040] Reference Figure 1 、 Figure 3 and Figure 6 The sealing assembly 37 includes an oil inlet 371. The left side of the hollow plate 1 is connected to the oil inlet 371. The outer side of the oil inlet 371 is threadedly connected to a threaded cover 372. By fixing the threaded cover 372 to the oil inlet 371, dust can be prevented from entering the interior of the device. The penetration assembly 38 includes a positioning frame 381. The inner side of the top cover 24 is provided with a positioning frame 381. The inner side of the positioning frame 381 is fixedly connected to an observation window 382. The operation of the device can be easily observed through the positioning frame 381 and the observation window 382.

[0041] Specifically, the oil inlet 371 can be used to add and replenish oil into the hollow plate 1, and the rotating threaded cover 372 can prevent dust from entering the inside of the device when not in use. The observation window 382 that passes through the inner side of the positioning frame 381 can facilitate real-time observation of the flow of oil in the hollow plate 1 and the operation of the device.

[0042] Reference Figure 2 、 Figure 7 and Figure 8 , the protective component 49 includes an insulation plate 491, which is fixedly connected to the left and right sides of the outside of the oil pipeline 5 respectively. The left and right sides of the bottom of the insulation plate 491 are fixedly connected with brackets 492. The insulation plate 491 can improve the insulation effect of the device, and the bracket 492 can support the fuel injector 6; the left side of the mounting block 44 is rotatably connected to the knob 7, the right side of the knob 7 passes through the mounting block 44 and is fixedly connected to the threaded rod 45, and the threaded rod 45 can be driven to rotate by rotating the knob 7; the outer periphery of the hollow plate 1 is provided with slide grooves 8, and the U-shaped block 22 is slidably connected to the slide grooves 8. The slide grooves 8 can improve the stability of the movement of the U-shaped block 22;

[0043] Specifically, the insulation effect of the oil pipeline 5 can be improved through the insulation plate 491, and the fuel injector 6 can be pushed for positioning through the bracket 492 at the bottom. The threaded rod 45 can be easily rotated by turning the knob 7, and the stability of the U-shaped block 22 during movement can be improved through the slide groove 8.

[0044] Working principle: By pressing the U-shaped blocks 22 on both sides to move them and contract the double-headed spring rod 21, the movement of the U-shaped blocks 22 can drive the telescopic plate 23 to rotate. At this time, as the telescopic plate 23 moves, the top cover 24 and the connecting frame 25 are pushed upward. At this time, the heating rod 26 will move out from the outside of the heating block 27 and be pulled out from the connecting frame 25 as it slides. The heating rods 26 of different densities can be replaced according to needs. After the replacement is completed and the top cover 24 is re-closed on the top of the hollow plate 1, the heating block 27 is started to heat the heating rod 26, and the oil can be heated.

[0045] The oil can be discharged into the oil delivery pipe 5 through the oil outlet 31. At the same time, the sealing performance of the oil outlet 31 can be improved through the connection cover 32. When the hollow plate 1 needs to be dismantled for maintenance, the clamping block 36 is rotated to release the engagement with the rotating ring 34. Then, the rotating ring 34 rotates to push the clamping plate 35 on it to move, so that the clamping plate 35 is released from the engagement with the positioning block 33. In this way, the oil outlet 31 and the connection cover 32 can be quickly disassembled or fixed.

[0046] Finally, when the oil flows, it will push the paddle 47 and the auger 48 to rotate. The rotation of the auger 48 can improve the oil delivery effect. At the same time, the rotation of the paddle 47 will also drive the conical gear ring 410 to rotate, and drive the conical gear 411 to rotate as it engages. At this time, the transmission of the belt 43 can synchronously drive the rotating wheels 42 on both sides to rotate. At this time, rotating the threaded rod 45 along the mounting block 44 can drive the threaded block 46 and the right rotating wheel 42 to move, so as to control the rotation speed of the auger 48 by releasing or tightening the belt 43.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
