The specific embodiment

Embodiment 1

This example is the box-like hard packing housing of a kind of folding fastener of an electrothermal plate pot blocking device.In drain pan 1 and the lid shell 2 heating plate is housed all, between heating plate and the housing electric heating element is housed, control turn-knob 4 is contained on the hull outside wall, is respectively equipped with leg 3 on the upper wall surface of the lower wall surface of drain pan 1 and lid shell 2.

Lid shell hinge plate 6 is fixed on by fixed plate 11 and covers on the shell side wall, and is connected with drain pan hinge plate 7 hinges on being fixed on base side walls; Locking plate 8 upper wall surfaces are attached on the lid shell hinge plate side that is positioned at the hinge-point projection left and right sides, and hinge-point P equates with distance to inner side edge 6a and upper side edge 6c to covering the distance of shell hinge plate lower side 6b.The button 5 that retracing spring 10 is housed is arranged on drain pan 1 sidewall, and its end that stretches in the housing is connected with the locking plate 8 that is contained between the guiding parts 9, has the gap that rotates and stretch out for hinge plate on the sidewall of drain pan 1 and lid shell 2 joint faces.

This example lid shell hinge plate lower side 6b and upper side edge 6c are parallel to each other, and inner side edge 6a is vertical with lower side 6b.

When lid shell 2 is buckling state with drain pan 1, the lower side 6b of lid shell hinge plate leans against (see figure 6) on locking plate 8 upper wall surfaces, because locking plate 8 acts on lid shell hinge plate 6 sides of the hinge-point projection left and right sides, block its swivel arm and can not rotate, so the lid shell is locked in buckling state; Inside button push 5, driving locking plate 8 moves inwards, shell hinge plate lower side is covered in the disengaging of locking plate upper wall surface, hinge plate can rotate, the lid shell is opened, because hinge-point equates with distance to lower side 6b to the distance of inner side edge 6a, so forward the half-open position release-push to, during the locking plate elastic reset, the side of the hinge plate inner side edge 6a hinge-point projection left and right sides can be attached on locking plate 8 upper wall surfaces (referring to Fig. 7), make that swivel arm is forward and reverse all can not to rotate, this routine inner side edge 6a is vertical with lower side, so the lid shell is locked in the states of opening 90 degree; Pin button, the rotatable cover shell, because 6c is parallel with lower side for lid shell hinge plate upper side edge, and hinge-point equates with distance to lower side 6b to the distance of upper side edge 6c, so be opened to 180 degree release-pushes, locking plate 8 upper wall surfaces that reset can be attached on the side of the upper side edge 6c hinge-point projection left and right sides (referring to Fig. 8), and the lid shell is locked in the states of opening 180 degree, and the leg 3 of lid shell outside wall surface acts on bearing surface simultaneously with the leg 3 on the drain pan outside wall surface.

By on can find out, when hinge-point P to the distance of inner side edge 6a and hinge-point when lower side 6b distance equates, lid shell hinge plate 6 can be positioned semi-open state, open angle depends on the angle of inner side edge 6a and lower side 6b, when hinge-point P to the distance of upper side edge 6c and hinge-point when lower side 6b distance equates, lid shell hinge plate 6 can be positioned full open mode, open angle depends on the angle of upper side edge 6c and lower side 6b, so hinge-point is to the distance of covering shell hinge plate inner side edge and upper side edge, distance at least to a side will equate to lower side 6b distance with hinge-point, the lid shell could be locked to an open mode at least, present embodiment is to interior, last two sides distance all equates, so may be locked in two open angle states.As a same reason, the inner side edge of different angles is arranged, and the distance of hinge-point to the distance of each inner side edge and hinge-point to lower side covered the open mode that the shell hinge plate can be locked in a plurality of angles when equating when a plurality of and lower side 6b are set.

The electrothermal plate pot adopts the utility model structure, has the saving space, carries advantage easy for operation, and when opening and using, and can make to cover shell and drain pan is in the lock state, and safety of operation is reliable.

Embodiment 2 (Fig. 9～Figure 11)

This routine difference from Example 2 is: the upper wall surface that locking plate 8 is positioned at the hinge-point P projection outside is provided with protruding step 8a, lid shell hinge plate 6 lower side 6b be provided with can with the locking plate upper wall surface step 8a convex-concave cooresponding recessed step 6d of embedding combination mutually, hinge-point P equates with distance to lower side 6b, inner side edge 6a, upper side edge 6c to the distance of step 6d.

When lid shell and drain pan are in buckling state, not only forward and reverse the blocking of locking plate 8 upper wall surfaces covered shell hinge plate swivel arm, and the step 8a on its upper wall surface blocks the step 8d that covers shell hinge plate lower side, to cover shell more securely and be locked in buckling state, equally open 90 and spend and 180 when spending states when lid shell and drain pan are in, step 8a on the locking plate 8 can block the cross-linking part of covering shell hinge plate lower side and inner side edge and the cross-linking part of inner side edge and upper side edge respectively, is locked in cooresponding open mode more securely thereby will cover shell.
