Description

A kind of engine jettison gear and engine sump tank

Technical field

The utility model is related to technical field of engines more particularly to a kind of engine jettison gears and engine oil pan Shell.

Background technology

Machine oil is the lubrication cooling liquid mediums of mainstream in current engine, in order to ensure it moistens ring cooling quality, is needed Oil change at regular intervals；Current most of engine be all by installed on engine sump tank the form of oil-draining screw come In-engine discarded machine oil is discharged, in actual engine maintenance maintenance work, scrap machine is discharged back-outing oil-draining screw It when oily, is easily scalded by the machine oil of high temperature, and general engine sump tank can precipitate a large amount of greasy filth, be put using common Oily screw fashion oil extraction is difficult greasy filth to be discharged, but it is preferable to the leakproofness of machine oil by the way of oil-draining locknut, at present Can be played in existing replacement device prevents the effect of scald maintenance personal well, but its leakproofness and operability exist Larger defect, a kind of jettison gear as described in Chinese patent document 201720296151.5, the device are oily when draining the oil Tube top movable valve plug opens sealing valve, and machine oil is flowed out from the gap of sealing valve and valve body, the disadvantage is that machine oil is flowed out from gap, Mass rate of emission is slow, needs to realize by attachment devices such as evacuators and quickly drain the oil, although the device is filled equipped with sealing ring Increase sealing effect is set, but is consequently exerted at the pressure on sealing device and only provides by elastomeric element, because engine works When machine oil there is certain pressure, and if it is being used in automobile engine, automobile jolts because of road conditions, easily makes seal member Generate to loosen and lead to oil leakage, and need during discharging machine oil it is continual withstand spool, operate and be more troublesome.

Utility model content

In order to solve the problems of the above-mentioned prior art, the utility model proposes a kind of engine jettison gear and Engine sump tank has the advantages that easy to operate, production cost is low and drains the oil fireballing.

What the technical solution of the utility model was realized in：

A kind of engine jettison gear, which is characterized in that including shell, turn plug, locking spring, sealing valve block, connection Bar, the turn plug, locking spring, connecting rod are all located in the shell, and circumference is equipped with external screw thread beyond the Great Wall for the turn, described Housing cavity wall is equipped with internal thread, and the shell is equipped with open end, sealed end, oil leak hole, and the turn plug is from the shell Open end is screwed on the housing cavity wall, and the end face of the turn plug towards the shell is equipped with counterbore, and other end is solid A fixed screw rod, described locking spring one end is connected in the counterbore, and the other end is resisted against the sealed end of the shell, described Sealed end is equipped with a through-hole, which is equipped with a stage portion abutted with the sealing valve block, and described connecting rod one end is fixed on The sealing valve block corresponds on the end face of the through-hole, and the other end is fixed on the bottom face of the counterbore, the sealing valve Block is equipped with a sealing ring, and the outer wall that the shell corresponds to the sealing valve block is equipped with seal groove corresponding with the sealing ring, The sealing ring is socketed a sealing ring.

In this engine jettison gear of the utility model, the sealing one side of the valve block far from the shell is equipped with Rotating part, the rotating part include rotation fixed pole, spill spin block, flabellum, and the rotation fixed pole is fixed in the sealing valve block, described The excircle for rotating fixed pole is equipped with a bulge loop, and the spill spin block is rotatably socketed in the rotation fixed pole, and is equipped with and institute The annular groove of bulge loop cooperation is stated, the flabellum is fixed on the spill spin block, and where rotation direction towards the sealing valve block Direction.

On this basis, the utility model also provides engine sump tank, it is characterised in that the engine sump tank packet Starting jettison gear containing above-mentioned one kind.

This engine jettison gear and engine sump tank for implementing the utility model, have the advantages that： When maintenance personal needs replacing engine inner engine oil, only it need to be connected to engine oil drum with the oil leak hole in oil pipe and jettison gear, revolved Turn to start to drain the oil after screw rod opens sealing valve block, machine oil directly flows into engine oil drum from jettison gear, avoids machine oil direct It sprays and scalds maintenance personal, the rotation of the rotating part in device makes the machine oil in machine oil shell generate vortex in outflow, stirs The greasy filth of dynamic oil sump bottom precipitation, makes it be discharged together with machine oil, the turn plug in jettison gear is screwed after draining the oil, is made Sealing valve block abuts against in the shell surface of jettison gear；Without increasing maintenance personal's compared with existing bolt drains the oil mode Additional workload and operation it is safer laborsaving.
