The guiding skewed slot of said positioning disk by the locating slot of uncapping, gathering sill, close and cover locating slot three parts and seamlessly transit and constitute.
Guiding mechanism on the described snap close is clasp or projection.
Said positioning disk is provided with upwardly extending finger, and the other end of finger directly or indirectly is connected with the folding lid and revolves hand, and said folding lid revolves hand and exposes the cover outside, revolves the hand rotation when external force drives the folding lid, and this folding lid revolves the hand-motion positioning disk and rotates forward or backwards.
The position corresponding with finger is provided with the gathering sill that extends along circumferentially on the said mounting flange, and finger revolves the hand interlock with the folding lid after passing gathering sill.
Said mounting flange upper edge circumferentially also is provided with spacing hole, and positioning disk is provided with corresponding screw, and the screw that passes spacing hole links to each other with screw, positioning disk is rotatably connected on mounting flange, and spacing hole limits the slewing area of positioning disk.
The bottom of said positioning disk is provided with cover plate, and the cover plate upper end is provided with heavy stand, and positioning disk places on the heavy stand.
After said connector passes pilot hole, snap close and mounting flange are flexibly connected.
The bottom of said cover plate is provided with retainer ring; Be provided with the sealing ring of pot in the sealing between retainer ring and the cover plate; Said retainer ring is provided with double-screw bolt, and passing pilot hole is screw with the connector that snap close and mounting flange flexibly connect, and said screw is fixed on the double-screw bolt of retainer ring.
Beneficial effect of the present invention mainly is: reduced the frictional force of detaining tooth and interior pot in the folding lid process, easy to operate, technology is simple, and cost is low.

The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
Like Fig. 1, shown in 2, electric pressure cooking saucepan of the present invention comprises cover 1, mounting flange 2, positioning disk 3, cover plate 4, snap close 5, retainer ring 6, sealing ring 7, interior pot 8.Mounting flange 2, positioning disk 3 be coaxial to be arranged at cover 1 and interior pot 8, and circle distribution has a plurality of snap closes 5 between mounting flange 2 and the positioning disk 3.The bottom of positioning disk 3 is provided with cover plate 4, and cover plate 4 upper ends are provided with heavy stand 41, and positioning disk 3 places on the heavy stand 41.The bottom of cover plate 4 is provided with retainer ring 6, is provided with the sealing ring 7 of pot in the sealing between retainer ring 6 and the cover plate 4, and retainer ring 6 is provided with double-screw bolt 61.
As shown in Figure 3, snap close 5 is provided with clasp 51, button tooth 52, pilot hole 53, is provided with the guide groove 22 that is disposed radially with snap close 5 corresponding positions on the mounting flange 2, and correspondence is provided with guiding skewed slot 31 on the positioning disk 3.Guiding skewed slot 31 by the locating slot 32 of uncapping, gathering sill 33, close and cover locating slot 34 3 parts and seamlessly transit and constitute.Pilot hole 53 on the snap close 5 is consistent with guide groove 22 directions; The connector 11 that passes pilot hole 53 flexibly connects snap close and mounting flange 2; This connector 11 is a screw; After screw passed the circular hole 23 that is arranged on the mounting flange 2, behind the through hole on the pilot hole 53 that passes snap close 5 again and the cover plate 4, the end of screw was fixed on the double-screw bolt 61 of retainer ring 6.
Mounting flange 2 directly or indirectly is fixedly connected with cover 1; The button tooth 52 of snap close 5 fastens with interior pot 8 each other, and the clasp 51 of snap close 5 is plugged in the guiding skewed slot 31 of positioning disk 3, and positioning disk 3 is provided with upwardly extending finger 10; The other end of finger 10 directly or indirectly is connected with the folding lid and revolves the hand (not shown); The folding lid revolves hand and exposes cover 1 outside, revolves the hand rotation when external force drives the folding lid, and this folding lid revolves hand-motion positioning disk 3 and rotates forward or backwards.Be provided with the gathering sill 25 that extends along circumferentially with finger 10 corresponding positions on the mounting flange 2 in addition, finger 10 passes gathering sill 25 backs and directly or through link gear and folding lid revolves the hand interlock.In the folding lid process, positioning disk 3 rotating band moving lock buttons 5 are along guide groove 22 radial motions of mounting flange 2, and the button tooth 52 of snap close 5 fastens with interior pot 8 or breaks away from.
In addition; Circumferentially also be provided with spacing hole 21 in mounting flange 2 upper edges; Positioning disk 3 is provided with corresponding screw 35, and the screw 9 that passes spacing hole 21 links to each other with screw 35, and positioning disk 3 is rotatably connected on mounting flange 2; And spacing hole limits the slewing area of positioning disk, and makes positioning disk 3 and mounting flange 2 keep concentric fit.
As shown in Figure 4, be the vertical view of mounting flange 2, positioning disk 3, cover plate 4, snap close 4, sealing ring 7, retainer ring 6 assembling back composition cover plate assemblies.Finger 10 drives positioning disk 3 rotations, does radial motion through placing the clasps 51 driving snap closes 5 in the skewed slot 31 that leads, and realizes the fastening or the disengaging of button tooth 53 and interior pot 8.
