Dynamic stretch, and since tension spring is no longer as hook is swung up and down, has prevented tension spring and has been likely to occur during the swing
Obscission, and then avoid the risk of tension spring failure of adjustment;
2, the active force steering mechanism combined by the way that drawstring is arranged with pulling force steering assembly, can be such that tension spring is in always
Horizontality, while also having prevented the pivoting friction process of tension spring and fixed block, to reduce tension spring and fixed block friction damage
Bad risk substantially prolongs the service life of tension spring adjustment structure;
3, the active force steering mechanism combined by the way that drawstring is arranged with pulling force steering assembly, during door open and close, by
It is driven in the phase mutual friction of drawstring and pulling force idler wheel, can effectively convert the speed and strength with buffered gate open and close, it is ensured that switch
Stability when door, extends the service life of dish-washing machine;
4, through setting gasket on the hook of hinge link block, effectively isolation is corresponding is linked up with and drawstring and hinge pin
Direct contact, protect drawstring and hinge pin from hook fray, substantially prolong the service life of tension spring adjustment structure, and
Effectively eliminate the noise that friction generates.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1-Fig. 8, the door tension spring adjustment structure of this table dish-washer, including liner 1, door-plate 2 and pedestal 3, and set
The hinge component being placed between door-plate 2 and pedestal 3, liner 1 are assemblied in 3 top of pedestal from top to bottom, and door-plate 2 passes through hinge component
It is articulated with 3 front side of pedestal;Hinge component includes hinge support block 4, tension spring 7 and hinge link block 9, and hinge support block 4 passes through spiral shell
Nail is fixed on 3 side of pedestal, and hinge link block 9 is fixed on 2 bottom of door-plate, hinge support block 4 and hinge link block 9 by screw
Mutually rotation connection rotates door-plate 2 relative to liner 1, and then opens and closes 1 inner cavity of liner;7 one end connects hinge link block 9 of tension spring,
