The specific embodiment
Describe performance of the present invention in detail below in conjunction with accompanying drawing, but they do not form limitation of the invention, only for example.Simultaneously by illustrating that advantage of the present invention will become more clear and easily understand.
Consult accompanying drawing known: pressure cooker upper handle of the present invention, it comprises upper handle handle body A, it is characterized in that it also comprises the button 3 of the button hole 2 that is positioned at upper handle handle body A side, guard plate 5, rotatable card angle 8, stopping valve E, draw-in groove 4 is arranged on button 3, guard plate 5 one sides have card base 6 to be positioned at draw-in groove 4, stopping valve E is positioned at the front end of guard plate 5, button 3 is fixed on upper handle handle body A by locating shaft 7, the opposite side of guard plate 5 has rotatable card angle 8, guard plate 5 and rotatable card angle 8 are positioned at the chute 9 on upper handle handle body A, chute 9 communicates with button hole 2, the front end of guard plate 5 is spacing by spring 10, bossed sliding angle 11 between rotatable card angle 8 and button 3 on guard plate 5, cover plate 12 is fixed on upper handle handle body A, the sliding angle 11 of projection is limited in the locating slot 13 on cover plate 12, rotatable card angle 8 is useful on the sliding angle 11 of projection is positioned to interior two of the front-end and back-end working position of locating slot 13 (as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 8, Figure 12, shown in Figure 13).
On rotatable card angle 8, locating dowel 81 is arranged, torsion spring 82 is sleeved on locating dowel 81, and is positioned at the locating hole 51 of guard plate 5 sides, and this structure can be rotated flexibly, is convenient to the transmission (as shown in Fig. 7, Fig. 9) of button actions.
Rear end one side of chute 9 has convex 91, locating dowel 81 is positioned at 8 stage casings, rotatable card angle, the upper end at rotatable card angle 8 is grab 84, grab 84 contacts with cover plate 12 or is positioned at cover plate 12 flush ends, the lower end at rotatable card angle 8 is support body 83, and support body 83 contacts with the front end in contact of convex 91 or with convex 91 upper surfaces.This structure can pass to spring and stopping valve by the action of button transmission by guard plate exactly by rotatable Ka Jiao, and this action is located to (as shown in Fig. 2, Fig. 7) exactly.
On pressure cooker left-hand seat convex 91, transition inclined-plane 92 is arranged.The support body 83 that this structure is convenient to the lower end at rotatable card angle 8 moves to convex 91 front ends from convex 91 upper surfaces smoothly, or from convex 91 nose motion to convex 91 upper surfaces (as shown in Fig. 2, Fig. 7).
In the lower end of upper handle handle body A one side limited location projection 21, the opposite side in the lower end of upper handle handle body A has gathering sill 22, and chute 9 is between spacing projection 21 and gathering sill 22.This structure is and the structure of lower handle coupling, is convenient to uncap and closing lid (as shown in Figure 2).
The pressure cooker open and close lid mechanism, it comprises above-mentioned pressure cooker upper handle 1 and pressure cooker lower handle B (as shown in Figure 10, Figure 11, Figure 12, Figure 13).
Pressure cooker upper handle of the present invention and cover opening-closing mechanism thereof are arranged on the pot cover C and pot body D of pressure cooker, and it comprises upper handle 1, lower handle B and stopping valve E.Wherein, upper handle 1 comprises the parts such as upper handle handle body A, button 3, guard plate 5, spring 10.
It is upper that upper handle 1 is fixedly connected on pot cover C, and middle part is a chute 9, for guard plate 5 parts such as grade are installed.Guard plate 5 is loaded in chute 9, and there is a card base 6 its side, and this card base is positioned at the draw-in groove 4 on button 3.Chute 9 connects with button hole 2, and it is upper that button 3 is fixed on upper handle handle body A by locating shaft 7, and be positioned at button hole 2.By pressing button 3, it is rotated around locating shaft 7, drive draw-in groove 4 rotations, thereby promote guard plate 5, move forward.
Lower handle B is fixedly connected on the pot body D of pressure cooker, and lower handle B has a guiding convex B1 corresponding to snap fit 84 positions of rotatable card base 8.As shown in figure 10, the end of guiding convex B1 is transition inclined-plane B3.In the closing lid process, the snap fit 84 on rotatable card angle 8 is upwards pushed by transition inclined-plane B3, thereby drive rotatable card angle 8, rotates.After rotate at rotatable card angle 8, the front end that its support body 83 breaks away from convex 91 is faced directly, and moves at the upper surface of convex 91, thereby guard plate 5 can be moved backward.
Also have a limited impression B2 on lower handle B, this groove is L-shaped, and corresponding with guard plate 5 De Hua angles 11, bottom.In the closing lid process, snap fit 84 on rotatable card base 8 is upwards pushed by transition inclined-plane B3, thereby when the front end that makes rotatable card angle 8 turn to its support body 83 disengaging convexes 91 is faced directly, under the effect of spring 10, guard plate 5 moves backward, and makes shoes 11 snap in limited impression B2.Now, the L shaped straight flange of the sliding limited groove B2 in angle 11 blocks, thereby causes sliding angle 11 can not rotate with respect to lower handle B together with guard plate 5 and upper handle 1.
As shown in Figure 3 and Figure 4, at the front end of guard plate 5 with a bayonet socket 54.If pot cover C and a pot body D do not fasten and do not put in place, when upper handle A and lower handle B are not incorporated into fully, the support body 83 at rotatable card angle 8 just withstands on the front end of convex 91, and guard plate 5 can not be retreated.Now the bayonet socket on guard plate 5 54 staggers with the position of stopping valve E, and stopping valve E is just blocked in the front portion of guard plate 5, makes stopping valve E not increase, and causes sealing, and the pressure in pot also just can not rise.Therefore, only have when upper handle 1 and lower handle B are incorporated into fully, the pressure in pot could rise, and pressure cooker is normally used, thereby guarantee its security performance.
When pressure cooker normally uses, stopping valve E is risen by a pot internal gas pressure effect, makes the pressure cooker sealing, thereby makes pot internal gas pressure can continue to rise.Now, stopping valve E rises up in the bayonet socket 54 of guard plate 5, stops guard plate 5 to move forward, thereby button 3 can't be rotated, and also just can't make sliding angle 11 exit from limited impression B2, and pot cover C also just can't open.At the pot internal gas pressure, during higher than ambient pressure, stopping valve E just can not fall, and while so just having guaranteed, in pot, pressure is arranged, can't open pot cover C.
Only have and drop to when consistent with ambient pressure when a pot internal gas pressure, stopping valve E just can fall because of self gravitation.Now, as long as turn knob 3 just can promote guard plate 5 by card base 6 and move forward, also just can open pot cover C simultaneously.
In addition, in the closing lid process, when the snap fit 84 at rotatable card angle 8 by jack-up, while making guard plate 5 retreat, guard plate 5 can impinge upon on upper handle handle body A under the effect of spring 10, produces clear and melodious impact sound, thereby remind consumer's closing lid to put in place, avoid occurring maloperation.
In the present invention, unaccounted part is prior art.
