Utility model content
Hold caducous problem for existing washing machine back shroud, the utility model provides a kind of back shroud of difficult drop-off.
The technical solution of the utility model is:
A kind of back shroud of difficult drop-off, comprise the back shroud body with installing hole, described back shroud body upper punch is pressed with the projection as reinforcement, the middle part of described projection has towards the groove of back shroud body recess, the relative both sides of described back shroud body have mounting limit and fillet respectively, described mounting limit from back shroud body edges backward cover board body side turnover, described fillet from back shroud body edges backward cover board body opposite side turnover.
Described groove makes back shroud intensity higher, in addition, the basis fixing back shroud at traditional self-tapping screw increases mounting limit and fillet, and mounting limit is for being articulated in the housing of washing machine, and fillet adopts and is bolted on the housing of washing machine.Large at the self-tapping screw of installing hole usually than used, when thus vibrating, back shroud just has the space of movement, can the side-lining of back shroud toward fillet by adjusting bolt, the edge of installing hole is resisted against on self-tapping screw tightly, back shroud does not have mobile space, is just not easy to produce to loosen.
As preferably, formed between described mounting limit and back shroud body and mount mouth, described mounting mouth is enlarging.
As preferably, in described mounting mouth, there is lead-in chamfered.
As preferably, the angle of described fillet and back shroud body is 90 degree.
As preferably, described fillet offers at least two bolt mounting holes.
As preferably, the base angle of described groove is obtuse angle.
Existing washing machine back shroud is typically provided with the jack of three socket power line plugs, but often occurs the situation that socket power line plug drops, and mainly after length service time, jack becomes large, and socket power line plug is fixing loosely.
As preferably, described back shroud body is provided with power-line plug putting hole, and the edge movable of described power-line plug putting hole is provided with blank cover.
Power-line plug putting hole is used for whole power-line plug to stretch into washing machine back shroud and hides in interior washing machine shell, does not worry the problem that power-line plug comes off from washing machine back shroud so completely.Described blank cover is used for covering power-line plug putting hole.
In order to blank cover and power-line plug putting hole seal tight, preferably, the edge of described blank cover has breach.Described breach can stretch out by power supply source line.
In order to fixed power source line, preferably, described back shroud body is fixed with the clip of band caulking groove, the clip of described band caulking groove and power line interference fit.
The back shroud of difficult drop-off of the present utility model, increasing groove in raised central portion on the one hand makes the intensity of back shroud increase, the opposing party increases the adhesion of mounting limit and fillet reinforcement back shroud and washing machine shell, and can the side-lining of back shroud towards fillet by bolt, installing hole is pushed against with the self-tapping screw for fixing back shroud, and during vibration of washing machine, back shroud is not easy to loosen.
