Description

Technical Field

[0001] The utility model relates to the technical field of engine oil level detection, and more particularly to an engine oil dipstick. Background Art

[0002] The oil dipstick is an engine component used to check the oil level in the oil pan. A lack of oil in the engine can cause engine failure. Because some oil from the oil pan enters the lubrication oil passages when the engine is running, it's important to stop the engine, allow the oil to drain back into the oil pan, and then use the dipstick to check the oil level.

[0003] However, some user scenarios require the engine to run continuously. During engine operation, some oil enters the lubrication passages, causing the oil level in the oil pan to drop. Using the existing oil dipstick according to previous standards can result in significant errors and misjudgment of the oil level. Utility Model Content

[0004] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art, and the purpose of the present invention is to provide an engine oil dipstick that can reduce misjudgment.

[0005] The technical solution of the utility model is: an engine oil dipstick, comprising an oil dipstick body, a buffer groove and a transparent cover covering the buffer groove at the lower end of the oil dipstick body, an exhaust port and an oil inlet at the upper and lower ends of the buffer groove, respectively, and a static upper scale line, a dynamic upper scale line, a static lower scale line, and a dynamic lower scale line are sequentially arranged in the buffer groove from top to bottom.

[0006] As a further improvement, a pull ring is provided at the upper end of the oil dipstick body.

[0007] Furthermore, an operating block is provided on the upper half of the pull ring to increase the operating area.

[0008] Furthermore, the operating block is composed of two half blocks, and the two half blocks are buckled on both sides of the upper half of the pull ring and locked by a first screw.

[0009] Furthermore, a dust cover is provided at the connection between the pull ring and the oil dipstick body.

[0010] Furthermore, the pull ring and the oil dipstick body are both made of metal, and the pull ring and the oil dipstick body are connected by threads or welding.

[0011] Furthermore, the cross section of the buffer groove is a semicircular structure.

[0012] Furthermore, the transparent cover is bonded to the oil dipstick body by glue.

[0013] Furthermore, one side of the transparent cover plate is hinged to one side of the oil dipstick body via a hinge, and the other side of the transparent cover plate is buckled to the other side of the oil dipstick body via a snap fastener.

[0014] Furthermore, one side of the transparent cover plate is hinged to one side of the oil dipstick body via a hinge, and the other side of the transparent cover plate is locked to the other side of the oil dipstick body via a second screw.

[0015] Beneficial effects

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The utility model provides a static upper scale line, a dynamic upper scale line, a static lower scale line, and a dynamic lower scale line, so that the oil amount can be measured when the engine is stopped and when the engine is running. The static scale line is used for detection and evaluation during stop measurement, and the dynamic scale line is used for detection and evaluation during operation measurement, which can reduce misjudgment. At the same time, the buffer tank is covered by a transparent cover plate, and the oil waves generated by the engine vibration hit the transparent cover plate, but the buffer tank is not affected, which can reduce the detection error caused by the oil waves generated by the engine vibration.

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0024] See Figures 1 to 4An engine oil dipstick includes an oil dipstick body 1, a buffer tank 2 provided at the lower end of the oil dipstick body 1, and a transparent cover plate 3 covering the buffer tank 2. An exhaust port 4 and an oil inlet 5 are provided at the upper and lower ends of the buffer tank 2, respectively. The buffer tank 2 is provided with, from top to bottom, a static upper scale line 6, a dynamic upper scale line 7, a static lower scale line 8, and a dynamic lower scale line 9. When the oil dipstick is inserted into the engine, engine oil enters the buffer tank 2 through the oil inlet 5, and gas in the buffer tank 2 is discharged through the exhaust port 4.

[0025] When measuring when the engine is stopped, the static upper scale line 6 and the static lower scale line 8 are used for detection and evaluation. When measuring when the engine is running, the dynamic upper scale line 7 and the dynamic lower scale line 9 are used for detection and evaluation. That is, this oil dipstick can be used to measure the oil amount when the engine is stopped and when it is running, which can reduce misjudgment.

[0026] In addition, the static upper scale line 6, the dynamic upper scale line 7, the static lower scale line 8, and the dynamic lower scale line 9 are set in the buffer tank 2, and then the buffer tank 2 is covered by the transparent cover 3. The engine vibration generates oil waves that hit the transparent cover 3, but the buffer tank 2 is not affected, which can reduce the detection error caused by the oil waves generated by the engine vibration.

[0027] The upper end of the oil dipstick body 1 is provided with a pull ring 10. As a further improvement, the upper half of the pull ring 10 is provided with an operating block 11 that can increase the operating area. When inserting or withdrawing the oil dipstick, the finger acts on the operating block 11, the finger force area is large, and the operation is simpler and more convenient.

[0028] Specifically, the operating block 11 is composed of two halves, which are buckled on both sides of the upper half of the pull ring 10 and locked by the first screw 12.

[0029] A dust cover 13 is provided at the connection between the pull ring 10 and the oil dipstick body 1 for covering the oil hole.

[0030] In this embodiment, the pull ring 10 and the oil dipstick body 1 are both made of metal, and the pull ring 10 and the oil dipstick body 1 are connected by threads or welding. The cross section of the buffer groove 2 is a semicircular structure.

[0031] In one embodiment, the transparent cover 3 is bonded to the oil dipstick body 1 by glue.
