Stretching clamping type engine oil pan oil drainage blocking system and method for applying same

Abstract

The invention discloses a stretching clamping type engine oil pan oil drainage blocking system which comprises an inner fixing seat, an outer blocking component and expansion springs. The inner fixingseat comprises a fixing front column, a fixing middle column and a fixing rear column, the outer blocking component comprises a front insertion column, a middle insertion column and a rear clamp body, the front insertion column and the middle insertion column are matched with inner cavities of the fixing front column and the fixing middle column in an insertion manner, the middle insertion columnand the expansion springs which are arranged in the fixing middle column can be driven by one another via a piston sleeve, the fixing rear column, an upper arc plate and a lower arc plate are clampedto form an upper clamp groove and a lower clamp groove, the upper arc plate and the lower arc plate are connected onto the fixing rear column, the rear clamp body comprises an upper clamp block and alower clamp block, the upper clamp block and the lower clamp block which are connected with the rear end of the middle insertion column are correspondingly clamped with the upper clamp groove and thelower clamp groove, and a transparent observation block is embedded in a front column cavity and is arranged in a position between the front end of the front insertion column and the outer side surface of the fixing front column. The stretching clamping type engine oil pan oil drainage blocking system in the design has the advantages that threaded connection, torque control or optional assembling / detaching tools can be omitted, and the stretching clamping type engine oil pan oil drainage blocking system is easy to operate and high in controllability.

Description

technical field [0001] The invention relates to an oil drain screw plug structure of an engine oil pan, which belongs to the field of engines, in particular to a stretching and locking type engine oil pan oil drain plugging system and a method of use thereof, which are particularly suitable for avoiding plugging and dismantling of threaded connections mode without torque control. Background technique [0002] When the engine reaches the maintenance mileage, it is necessary to replace the oil in the oil pan. Use a wrench to unscrew and remove the oil drain plug on the oil pan to release the internal oil, then tighten the oil drain plug and re-inject new oil. At present, the oil drain plugs of engines on the market are all connected with the oil drain plug seats on the oil pan in a threaded form. For aluminum alloy and plastic oil pans, their strength is lower than that of steel stamped oil pans. It often happens that users in the market do not follow the specified torque whe...
