Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engine oil discharge, in particular to an engine oil discharge mechanism. Background Art
[0002] The oil discharge of the diesel engine of the road sweeper is the key to maintenance. During maintenance, it is necessary to open the oil drain mechanism on the engine, and use a container to catch the old, expired or contaminated oil discharged from the engine, and then replace it with an appropriate amount of new oil. After checking for leaks, start the engine to confirm normal operation. Regular maintenance and oil replacement can ensure the normal operation of the engine and extend its service life.
[0003] However, the engine oil drain mechanism on conventional road sweepers is prone to accidental touch or accidental collision due to the lack of effective anti-accidental touch measures. In particular, when the road sweeper workers are spraying and sweeping, they need to frequently open and close the water supply pipeline on the vehicle. The oil drain mechanism has a similar structure to the water supply pipeline, which is more likely to cause accidental touch or accidental collision by the operator, causing the oil drain hole to open accidentally and cause oil leakage, increasing safety hazards and maintenance difficulties. Utility Model Content
[0004] The utility model aims to solve at least one of the technical problems existing in the prior art.
[0005] To this end, one purpose of the utility model is to provide an engine oil drain mechanism, which limits the rotation of the wrench and prevents oil leakage caused by misoperation by setting slots on the wrench and the arc plate and inserting a pin into the slot on the arc plate.

[0009] Preferably, one end of the bottom of the bolt is threadedly connected to the valve stem inside the ball valve.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1 An embodiment of the utility model provides an engine oil discharge mechanism, comprising: an engine 1.
[0018] Among them, Figure 1 and Figure 2 As shown, an oil pump drain hole 2 is provided at the bottom of the engine 1, and a ball valve 3 is connected to one side of the oil pump drain hole 2. A wrench 4 is installed on the ball valve 3 through a bolt 6. The bottom end of the bolt 6 is threadedly connected to the valve stem of the ball valve 3. When the engine 1 is routinely maintained, the ball valve 3 is opened by turning the wrench 4 to open the channel of the oil pump drain hole 2, and the remaining oil in the engine 1 is discharged. After the discharge, the ball valve 3 is closed and new oil is added to the engine 1 to complete the maintenance operation.
[0019] Furthermore, the water outlet of the ball valve 3 is connected to the oil drain pipe 5. When the engine oil is discharged outward through the ball valve 3, the oil discharge direction can be guided by the oil drain pipe 5 to avoid being unable to control the oil discharge direction when the engine oil is discharged.
[0020] In this embodiment, Figure 2-Figure 3 As shown, an arc plate 8 passes through the bolt 6, the arc plate 8 is located at the bottom of the wrench 4, and a slot 9 is provided on the arc plate 8, a latch 10 is provided inside the slot 9, and a limiting convex ridge 11 is integrally formed on the outer wall of the arc plate 8, and a limiting rod 7 is welded on the ball valve 3.
[0021] When the engine 1 does not require routine maintenance, the wrench 4 will rotate to a position parallel to the ball valve 3, so that the ball valve 3 opens the oil pump drain hole 2. When the wrench 4 is rotated to a state where the ball valve 3 intersects vertically, the oil pump drain hole 2 can be closed, and it is convenient to insert the pin 10 into the slot 9. At this time, rotating the wrench 4 will cause one side of the wrench 4 to be blocked by the pin 10.
[0022] Further, see Figure 3 The latch 10 is a B-shaped pin, one end of the B-shaped latch 10 is located inside the slot 9, and the other end is located outside the slot 9, which increases the stability and durability of the latch 10.
[0023] It should be noted that the thickness of the curved plate 8 does not exceed 50 mm.
[0024] like Figure 2 and Figure 3 As shown, the limiting rod 7 can prevent the rotation angle of the wrench 4 from exceeding 180°.
[0025] The working steps of this scheme are summarized and sorted out according to the above technical scheme: the engine oil discharge mechanism of the utility model includes a ball valve 3 installed on the oil pump oil discharge hole 2. When the engine 1 is subjected to routine maintenance, the passage of the oil pump oil discharge hole 2 is opened by opening the ball valve 3 to discharge the remaining oil in the engine 1. After the discharge, the ball valve 3 is closed and new oil is added to the engine 1 to complete the maintenance operation.
[0026] When the engine 1 does not need routine maintenance, the wrench 4 will rotate to a position parallel to the ball valve 3, so that the ball valve 3 closes the oil pump drain hole 2, and the latch 10 is inserted into the slot 9 on the arc plate 8. At this time, rotating the wrench 4 will cause one side of the wrench 4 to be blocked by the latch 10. When the limiting ridge 11 is acted upon by the latch 10, it will abut against the limiting rod 7 so that the wrench 4 cannot be rotated, which effectively limits the rotation range of the wrench 4 and avoids oil leakage from the engine 1 caused by the operator accidentally touching the wrench 4 to turn it open. In addition, the latch 10 is reusable and can be reinserted into the slot 9 after the oil is discharged. Fewer structural parts are required and the cost is lower.
