Description
Technical field
The utility model relates to mechanical engineering pump technical field, particularly relates to a kind of pump cover detaching structure of sewage pump.
Background technique
Inner impurity removed by Current Domestic sewage pump, the pump cover of water pump need be broken, could remove.It is all locked with multiple bolt that conventional pump cover is installed fixing, and dismounting needs with instruments such as spanners.The production installation and removal inconvenience of sewage pump, it is inconvenient that user to remove in sewage pump impurity, dismantle multiple bolt, and when not having an instrument, efficiency is low.Therefore, how to ensure that user does not need special tool just can become urgent problem by metal cleaning equipment easily when sewage pump uses and all needs to remove contamination at every turn.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and gets final product the convenient pump cover detaching structure carrying out the sewage pump cleared up without the need to special tool.
The technical solution adopted in the utility model is:
A kind of pump cover detaching structure of sewage pump, comprise the pump housing, pump cover and pressing plate, the described pump housing, pump cover and pressing plate set gradually, pump cover and the pump housing are locked by a dismountable fixing-assembly and are paid by described pressing plate, described fixing-assembly comprises connecting screw rod, holding down bolt and tightening knob, described pump housing periphery wall is evenly provided with at least two group location chunks, location chunk comprises positioning block and lower positioning block, one end of described connecting screw rod is detachably installed between upper positioning block and lower positioning block by holding down bolt, described pump cover periphery wall is provided with the pump cover otic placode corresponding with locating chunk, described pump cover otic placode is provided with pump cover opening, the corresponding pump cover otic placode place of described pressing plate is provided with pressing plate otic placode, described pressing plate otic placode respective pump cover gab place is provided with pressing plate through hole, the other end of described connecting screw rod is by tightening knob fixing with on pressing plate through pump cover opening and pressing plate through hole successively.
Described upper positioning block and lower positioning block are respectively equipped with holding down bolt through hole.
Seal washer is provided with between the described pump housing and pump cover.
The lower end of described holding down bolt is provided with position limit pin, and position limit pin is positioned at the below of lower positioning block.
The utility model adopts above technological scheme, pump cover and the pump housing to be locked pay by described pressing plate by the fixing-assembly that is made up of connecting screw rod, holding down bolt and tightening knob.When needs dismounting pump cover, tightening knob of only need outwarding winding, takes off holding down bolt and pump cover can disassemble by connecting screw rod easily, so that user clears up.The pump cover of sewage pump can disassemble to clear up sewage pump without the need to special tool by the utility model easily.
