The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the inoperable electric-heating cooking utensil of this no inner sealing lid that the utility model provides, comprise: pot body 1, one end is rotationally connected with pot body 1 and the other end and pot body 1 manual cover assembly 2 that fastens, be located at the fastening draw-in groove 3 that is used for cover assembly 2 and pot body 1 fastening on pot body 1, be located at the movable sealing inner cap 5 of cover assembly 2 bottoms, be provided with rotating shaft 7 at cover assembly 2 and pot body 1 manual buckling end, be arranged with the engaging support mechanism that can rotate relative to this cover assembly 2 in the rotating shaft 7, the engaging support mechanism lower end is provided with bottom clasp 43, engaging support mechanism cooperates with movable sealing inner cap 5 so that cover assembly 2 fastens with pot body 1, during fastening, bottom clasp 43 is buckled in and fastens in the draw-in groove 3; Engaging support mechanism cooperates with cover assembly 2 by flexible member disposed thereon rotates engaging support mechanism clockwise direction cover assembly center, when no movable sealing inner cap, engaging support mechanism bottom clasp turns to fastening draw-in groove over top to the cover assembly center and is withstood, and cover assembly and pot body can not be fastened.
As Fig. 5, Fig. 6, shown in Figure 7, engaging support mechanism comprises button bar 4 and rotation latch hook 6, button bar 4 is the shaped as frame of leg for the lower ending opening two ends, bottom clasp 43 is arranged on 4 liang of leg bottoms of button bar, vertical button bar 4 main bodys of button bar 4 upper end both side ends are provided with the brace 46 of two band through holes, and button bar 4 is set in the rotating shaft 7 by this two brace 46; Rotation latch hook 6 is a T shape, and its upper end laterally is provided with through hole 64, and rotation latch hook 6 is installed in button bar 4 openings also by through hole 64 and button bar 4 coaxial settings; Flexible member is three torsion springs in the present embodiment, these three torsion springs all are set in the rotating shaft 7 and are separately positioned on button bar 4 two ends and rotation latch hook 6 upper center, be provided with first groove 65 of ccontaining its torsion spring 63 at rotation latch hook 6 middle parts, these rotation latch hook torsion spring 63 1 ends are stuck in first groove 65, and its other end is stuck on the cover assembly 2.Be respectively equipped with second groove 45 of ccontaining its torsion spring 44 at button bar 4 two ends, button bar torsion spring 44 1 ends are stuck in second groove 45, and its other end is stuck on the cover assembly 2.
When installing, rotating shaft 7 covers button bar 4 one end braces 46, button bar 4 one end torsion springs 44, rotation latch hook 6 upper end through holes 64, rotation latch hook torsion spring 63, button bar 4 other end torsion springs 44, button bar 4 other end braces 46 successively.Rotation latch hook 6 cooperates with movable sealing inner cap 5 and button bar 4 respectively, rotates latch hook 6 and button bar 4 and cooperates with cover assembly 2 by torsion spring separately respectively.Be specially: rotation latch hook 6 upper surfaces are provided with a boss 66 to a side at cover assembly 2 centers, and these boss 66 upper surfaces (being end face) engage with movable sealing inner cap 5 flanges; Rotation two ends, the left and right sides, another side, latch hook 6 upper end are equipped with an inclined platform, button bar 4 middle parts be provided with side by side two opposite with bottom clasp 43 openings and be positioned at the arc top clasp 42 of bottom clasp 43 tops, under 44 effects of button bar button spring, top clasp 42 protruding sides and inclined platform side 62 offset.
Fasten for the ease of cover assembly 2 and pot body 1, fasten draw-in groove 3 tops and be provided with the inclined-plane, when movable sealing inner cap 5 was arranged, engaging support mechanism bottom clasp 43 was positioned on the inclined-plane that fastens draw-in groove 3, and bottom clasp 43 can slide with it along the inclined-plane that fastens draw-in groove 3 and fasten.
For the anglec of rotation of restriction engaging support mechanism when movable sealing inner cap 5 is not installed, extend a spacing catch 47 obliquely in button bar 4 upper center.When no movable sealing inner cap 5, rotation latch hook 67 rotates around the shaft clockwise, make the inclined platform side 62 turn to the inside (promptly clockwise rotate) of button bar top clasp 42 along rotation latch hook 6, at this moment, the spacing catch 47 that extends owing to button bar 4 tops is stopped the top plan place that makes the bottom clasp rest on fastening draw-in groove 3 by cover assembly, as Fig. 2, shown in Figure 6, closes when covering, bottom clasp 43 withstands on and fastens draw-in groove 3 tops, cover assembly 2 can't be pressed down and can not fasten with pot body 1.
The left and right sides is provided with two through hole 8 on cover assembly 2, rotating shaft 7 is located in the two through hole, the position of rotating shaft 7 is when having made when normal mounting movable sealing inner cap 5, the rotation final position of rotation latch hook 6 engages with movable sealing inner cap 5, at this moment, engaging support mechanism bottom clasp 43 is positioned on the inclined-plane that fastens draw-in groove 3.
Operation principle of the present utility model is:
As Fig. 3, shown in Figure 4, in the time of in movable sealing inner cap 5 normally places cover assembly 2, because the existence of movable sealing inner cap 5, rotation latch hook 6 upper surfaces engage with movable sealing inner cap 5 flanges to boss 66 end faces that a side at cover assembly 2 centers is provided with, limited rotation latch hook 6 under the effect of button spring 63 the anglec of rotation and stop at clamped position, simultaneously under 44 effects of button bar button spring, because clasp 42 protruding sides in top offset with rotation latch hook 6 inclined platform sides 62, rotation latch hook 6 inclined platform sides 62 promote clasp 42 protruding sides, top, button bar 47 is rotated to the direction opposite with cover assembly 2 centers around the shaft, bottom clasp 43 turns to the top that pot body 1 fastens draw-in groove 3 inclined-planes at this moment, the user firmly closes downwards when covering, and bottom clasp 43 slips into along the inclined-plane that fastens draw-in groove 3 to fasten cover assembly 2 and pot body 1 are fastened.
As Fig. 1; shown in Figure 2; when no movable sealing inner cap 5 spacing; rotation latch hook 67 continuation around the shaft rotates clockwise; make the inclined platform side 62 turn to the inside (promptly clockwise rotate) of button bar 4 top clasps 42 along rotation latch hook 6; consequently button bar 4 bottom clasps 43 move to the fastening draw-in groove 3 top plan places on pot body 1; at this moment; the spacing catch 47 that extends owing to button bar 4 tops is stopped the top plan place that makes bottom clasp 43 rest on fastening draw-in groove 3 by cover assembly 2; close when covering; bottom clasp 43 withstands on and fastens draw-in groove 3 tops; cover assembly 2 can't be pressed down and with pot body 1 can not fasten, thereby finished defencive function.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
