Description

Oil pan with high locking force locking piece

The technical field is as follows:

the utility model relates to an engine spare part field especially relates to an oil pan with high locking force retaining member.

Background art:

the oil sump is the lower half of the crankcase and serves to close the crankcase as the housing for the oil sump, prevent the ingress of contaminants, and to collect and store the lubricating oil that flows back from the various friction surfaces of the diesel engine, dissipate some of the heat, and prevent the oxidation of the lubricating oil.

The oil sump is mostly formed by stamping a thin steel plate, and the oil sump is generally cast and formed by cast iron or aluminum alloy in a complex shape. At present, a lot of car enterprises on the market adopt the oil pan of plastics material, and the plastics oil pan generally all adopts the PA66 material to make, and the biggest advantage in aluminum alloy oil pan is compared in weight lighter in the plastics oil pan, uses the decibel that the plastics oil pan can control engine noise to a certain extent, and uses the plastics oil pan can save 20% -40% cost.

When a vehicle using a plastic oil pan is replaced with lubricating oil, the oil drain bolt 3 needs to be detached to drain old lubricating oil as shown by the fixture block 5 shown in fig. 4 and the oil drain bolt 3 shown in fig. 5, and when the oil drain bolt 3 is detached, the situation that the fixture block 5 connected with the oil drain bolt 3 on the oil pan falls off or even is twisted and cracked often occurs, which also occurs during installation, and shortens the service life of the oil pan.

The utility model has the following contents:

the utility model aims at prior art's defect, a oil pan with high locking force retaining member is provided, in order to solve when changing lubricating oil to the vehicle that uses the plastics oil pan, need dismantle the oil drain bolt, thereby the old lubricating oil of discharge, when dismantling the oil drain bolt, often appear screwing up the power too big, the fixture block that leads to on the oil pan and oil drain bolted connection appears droing, the condition of twisting the fracture appears even, the same such condition that has during the installation takes place, the problem of the life of oil pan has been shortened.

In order to achieve the above object, the present invention provides the following technical solutions: an oil pan with a high-locking-force locking member comprises a hollow oil pan main body, wherein an oil discharge port is formed in one side of the oil pan main body, the high-locking-force locking member is detachably mounted at the oil discharge port and comprises an oil discharge bolt and a locking member, the locking member is fixedly connected in the oil discharge port, and the oil discharge bolt is detachably connected with the oil pan main body through the locking member;

the retaining member includes the go-between, the go-between is installed in the oil drain, and the go-between is provided with all around and uses the go-between centre of a circle evenly to encircle the strip stopper that distributes as the center, and the stopper both ends are parallel and level with the go-between both ends, have the strip clearance between the two adjacent stoppers, and each stopper encircles along the oil drain and inlays, each stopper terminal surface and oil drain inner wall interference fit.

In order to guarantee the sturdiness and the life of retaining member, go-between and stopper gear column structure for integrated into one piece.

In order to improve the fastening nature of being connected between retaining member and the oil pan, the stopper is the trapezium structure, and its bottom width reduces to the top gradually to the parcel nature is stronger.

In order to be more convenient to disassemble and maintain, the connecting ring is internally provided with an internal thread matched with the oil drainage bolt.

In order to guarantee the stability of being connected between retaining member and the oil pan main part, retaining member thickness is unanimous with oil pan main part bottom thickness.

Borrow by above-mentioned scheme, the utility model provides a pair of oil pan with high locking force retaining member has following beneficial effect at least:

the utility model discloses a retaining member replaces the fixture block that prior art adopted, retaining member integrated into one piece's gear structure improved with oil pan main part between parcel nature and the occlusal force, can avoid the oil drain bolt in traditional connected mode too big because of screwing up the power, lead to coming off in the oil pan main part with oil drain bolted connection's fixture block appearance, appear twisting the condition of splitting even, the life of extension oil pan main part has reduced the cost of vehicle maintenance and maintenance.
