Description

Technical Field

[0001] The utility model relates to the technical field of engine oil nozzles, in particular to a high-efficiency lubricating tubular engine oil nozzle. Background Art

[0002] Traditional internal combustion engine piston cooling relies on the high-speed rotation of the crankshaft. This centrifugal force creates a centrifugal force that ejects the oil from the crankshaft. Most of the oil falls back into the oil pan, while a small amount splashes onto the pistons, cooling and lubricating them. This method of piston cooling is not only inefficient but also inadequate, resulting in a shortened piston lifespan.

[0003] In addition, when the existing oil nozzle is in use, the oil flowing in the nozzle will have a certain resistance due to the resistance of the flow channel and the limitation of the internal structure, which makes its circulation efficiency low. Moreover, after long-term use, the oil leaks out and cannot be sprayed to the designated position, which is very detrimental to the normal use of the engine and makes its lubrication efficiency low. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a high-efficiency lubricating tubular oil nozzle, which can solve the problem that when the existing oil nozzle is in use, the oil will have a certain resistance in the nozzle due to the resistance of the flow channel and the limitation of the internal structure, which makes its circulation efficiency low. After long-term use, the oil leaks from it and cannot be sprayed to the designated position, which is very detrimental to the normal use of the engine and makes its lubrication efficiency low.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: a high-efficiency lubricating tubular oil nozzle, comprising a nozzle sleeve, a nozzle pipe fixing seat fixedly connected to the nozzle sleeve, an elbow nozzle fixedly installed in the nozzle fixing seat, an inner circulation groove formed on the inner wall of the nozzle sleeve, the inner circulation groove being used to convey oil to the elbow nozzle pipe, the elbow nozzle pipe being connected to the inner circulation groove, and a mounting post being disposed in the nozzle sleeve;

[0006] The outer surface of the mounting post is provided with a thread for mounting, the mounting post is provided with a flow hole, the inner wall of the flow hole is provided with a sliding groove, the upper and lower ends of the sliding groove are tapered inclined surfaces, and the sealing steel ball is arranged in the sliding groove, and the sealing steel ball is adapted to the inner wall of the sliding groove;

[0007] Conical sealing rings are provided at both ends of the nozzle sleeve to improve the installation sealing performance;

[0008] The inner wall of the sliding trough is provided with a plurality of vertical flow grooves, and the plurality of vertical flow grooves are evenly arranged in a circular array.

[0009] Preferably, the vertical flow groove is used to improve the fluidity of the engine oil, and the inner wall of the sliding groove is provided with a circumferential flow channel hole.

[0010] Preferably, the circumferential flow channel hole is used to connect the flow hole and the inner annular flow groove.

[0011] Preferably, a hexagonal screw head is fixedly connected to the upper end of the mounting column, and an oil inlet is provided on the top of the hexagonal screw head.

[0012] Preferably, the oil inlet is connected to the inner circulation groove through a sliding groove, and a spring is provided in the sliding groove, and the spring is used to push the sealing steel ball upward.

[0013] Preferably, sealing conical grooves are provided at both ends of the nozzle sleeve, and two conical sealing rings are respectively located in the corresponding sealing conical grooves, and the conical sealing rings are used to press the sealing conical grooves.

[0014] Compared with the prior art, the present invention provides a highly efficient lubricating tubular oil nozzle, which has the following beneficial effects:

[0015] This high-efficiency lubricating tubular oil nozzle is constructed by opening a threaded hole for fixing the nozzle at a designated position on the engine, and then tightening a mounting post to install it on the threaded hole. During the process of tightening the mounting post, the nozzle sleeve will compress the conical sealing ring through two sealing conical grooves. At this time, the conical sealing ring will fill the gap between the nozzle sleeve and the mounting post, which can effectively ensure the sealing performance of the nozzle sleeve and avoid the problem of oil flowing out of the gap and failing to effectively reach the designated position to play a lubricating role.

[0016] This high-efficiency lubricating tubular oil nozzle has multiple circumferential flow channel holes that are evenly arranged in a circular array. This can improve the oil circulation efficiency when the nozzle is installed, so that the oil circulation efficiency will not be affected at any installation angle, and the oil usage efficiency is also improved.

[0017] This high-efficiency lubricating tubular oil nozzle has multiple vertical flow grooves evenly arranged in a circular array, so that when the oil drives the sealing steel ball to move, the spring can always be in the sliding groove, and the oil flows through the multiple vertical flow grooves, which avoids the problem that the sealing steel ball easily affects the efficiency of oil circulation when moving.

[0018] This high-efficiency lubricating tubular oil nozzle, when used, the oil pump will pressurize the oil, the oil is drawn out from the oil pan and pressurized and then sent to various parts of the engine that need lubrication. When it is delivered to the oil nozzle, the sealing steel ball will be pushed downward first, and the oil will enter the sliding groove from the oil inlet. At this time, although the sealing steel ball is pushed open by its own pressure, the sealing steel ball is still stably restricted by the sliding groove enclosure. The oil will flow from the vertical flow groove into the sliding groove, and then the oil will enter the inner annular flow groove from multiple circular flow channel holes. After entering the inner annular flow groove, the oil will enter the elbow nozzle under its own pressure, and finally be sprayed from the elbow nozzle to the engine piston. This spraying method helps the oil to cover the engine components more evenly and improve the lubrication effect.

[0019] This high-efficiency lubricating tubular oil nozzle forms a lubricating film on the surface of engine components through the sprayed oil, reducing friction and wear between components. At the same time, the oil also has a certain cooling effect, which can absorb and take away the heat generated by the engine components during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The outer surface of the mounting post 3 is provided with a thread 13 for installation. The mounting post 3 has a flow hole 16 formed inside. The inner wall of the flow hole 16 has a sliding groove 4 formed therein. The upper and lower ends of the sliding groove 4 are tapered inclined surfaces. The sealing steel ball 5 is arranged in the sliding groove 4 and is adapted to the inner wall of the sliding groove 4.

[0030] Conical sealing rings 12 are provided at both ends of the nozzle sleeve 1 to improve the sealing performance of the installation;

[0031] A plurality of vertical flow grooves 7 are formed on the inner wall of the sliding groove 4 , and the plurality of vertical flow grooves 7 are evenly arranged in a circular array.

[0032] Furthermore, the vertical flow groove 7 is used to improve the fluidity of the engine oil, and the inner wall of the sliding groove 4 is provided with a circumferential flow channel hole 8.

[0033] Furthermore, the circumferential flow channel hole 8 is used to connect the flow hole 16 and the inner annular flow groove 2 .

[0034] Furthermore, a hexagonal screw head 14 is fixedly connected to the upper end of the mounting column 3 , and an oil inlet 15 is formed at the top of the hexagonal screw head 14 .

[0035] Furthermore, the oil inlet 15 is communicated with the inner circulation groove 2 through the sliding groove 4. A spring 6 is provided in the sliding groove 4. The spring 6 is used to push the sealing steel ball 5 upward.

[0042] Working principle: This high-efficiency lubricating tubular oil nozzle is constructed by opening a threaded hole for fixing the nozzle at a designated position on the engine, and then tightening the mounting post 3 to be installed on the threaded hole through the thread 13. In the process of tightening the mounting post 3, the nozzle sleeve 1 will compress the conical sealing ring 12 through the two sealing conical grooves 11. At this time, the conical sealing ring 12 will fill the gap between the nozzle sleeve 1 and the mounting post 3, which can effectively ensure the sealing performance of the nozzle sleeve 1 and avoid the problem that the oil flows out of the gap and cannot effectively reach the designated position to play a lubricating role.

[0043] The high-efficiency lubricating tubular oil nozzle has multiple circumferential flow channel holes 8 that are evenly arranged in a circular array. This can improve the oil circulation efficiency when the nozzle is installed, so that the oil circulation efficiency will not be affected at any installation angle, and the oil use efficiency is also improved.

[0044] This high-efficiency lubricating tubular oil nozzle has multiple vertical flow grooves 7 that are evenly arranged in a circular array. When the oil drives the sealing steel ball 5 to move, the spring 6 can always be in the sliding groove 4, and the oil can flow through the multiple vertical flow grooves 7, which avoids the problem that the sealing steel ball 5 easily affects the efficiency of oil circulation when moving.

[0045] The high-efficiency lubricating tubular oil nozzle, when used, will pressurize the oil by the oil pump. The oil is drawn out from the oil pan and pressurized and then sent to various parts of the engine that need lubrication. When it is delivered to the oil nozzle, the sealing steel ball 5 will be pushed downward first. At this time, the oil will enter the sliding groove 4 from the oil inlet 15. Although the sealing steel ball 5 is pushed open by its own pressure at this time, the sealing steel ball 5 is stably restricted by the sliding groove 4 at this time. The oil will flow from the vertical flow groove 7 into the sliding groove 4, and then the oil will enter the inner annular flow groove 2 from multiple circumferential flow channel holes 8.
