Abstract
The utility model discloses a pressure cooker with hooks for locking, which comprises a cooker body and a cooker lid, wherein, a safety valve assembly, a pressure limiting valve assembly and a cross beam lid locking mechanism are arranged on the cooker lid, and both ends of a cross beam of the cross beam lid locking mechanism are hinged with hooks which are provided with lug bosses. The hinged points of the hooks and the cross beam are provided with torsion springs, and the mouth of the cooker body is provided with convex edges matched with the hooks. The whole pressure cooker has the advantages of artful design, simple structure, high safety and convenient operation, and the utility model is a product for replacing ordinary pressure cookers at present.
Description
The utility model relates to a kind of pressure cooker, particularly relates to a kind of pressure cooker of pot cover and pot body being locked by hook.
The locking of pressure cooker lid and pot body is the part that realizes pressure cooker function and security most critical.Present general pressure cooker, its locking are that the cooperation of the tooth that matches with pot body by pot cover realizes.This locking mode is opened the pot cover inconvenience, and sealing is relatively poor.The designer has proposed various improvement projects, a kind of efficient energy-saving safe pressure cooker is disclosed as Chinese patent ZL96247808.3, this utility model is a kind of cross bar lock cover type pressure cooker, include pot body and pot cover, curve form is made in the bottom of pot body, the upper end is provided with handle, and pot cover is provided with pressure limiting valve and cross bar locking closure mechanism, and handle is locked on the pot body by two semicircle beckets and connector.Its cross bar locking closure mechanism includes cross bar, degree of tightness nut, parbuckle screw, parbuckle screw seat, the degree of tightness nut is packed in the middle part of cross bar, the parbuckle screw seat is packed in the middle part of pot cover by connector, parbuckle screw revolves to be put in the degree of tightness nut, its lower end is on chute set on the parbuckle screw seat, and the contact-making surface of parbuckle screw and parbuckle screw seat is provided with ball, and control is operated to the folding of pot cover by mechanism by the cross bar locking closure.Whole pressure cooker structure is complicated, and security is not enough.
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, pressure cooker that security performance is good.
The technical solution adopted in the utility model is: a kind of pressure cooker locked by hooks, comprise pot body and pot cover, have safety valve complement, pressure limiting valve assembly and crossbeam locking closure mechanism on the pot cover, described crossbeam locking closure mechanism is made up of handle, crossbeam, top nut, screw rod, lower nut, top nut is packed in the middle part of crossbeam, lower nut is packed in the middle part of pot cover inside by connector, and screw rod revolves to be put in top nut; The hinged hook that has convex in described crossbeam two ends, hook is provided with torsion spring with the crossbeam hinged place; Pot body oral area has the bead that matches with hook.
Also be provided with outer cover on the crossbeam, pot cover is provided with sound prompt device.
The utility model passes through crossbeam locking closure mechanism and hook is locked pot cover and pot body, and hook firmly hooks the pot body, and sealing is strengthened greatly.Rotary handle, the relative pot cover of crossbeam position moves down, and convex withstands pot cover edge aft hook and automatically springs open on the hook, can open pot cover easily.Whole pressure cooker design is ingenious, simple in structure, safe and reliable, easy to use, is the renewal product of present usual pressure pot.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is a hook action schematic diagram of the present utility model;
Vertical view when Fig. 3 has outer cover for the crossbeam of utility model shown in Figure 1.
As figure, a kind of pressure cooker locked by hooks comprises pot body 18 and pot cover 11, and pot body 18 both sides have handle 1; Have safety valve complement 12, pressure limiting valve assembly 4 and crossbeam locking closure mechanism on the pot cover 11, described crossbeam locking closure mechanism is made up of handle 6, crossbeam 3, top nut 7, screw rod 8, lower nut 10, top nut 7 is packed in the middle part of crossbeam 3, lower nut 10 is packed in the middle part of pot cover 11 inside by connector, and screw rod 8 revolves to be put in top nut 7; For preventing that crossbeam 3 from moving, be provided with the anti-blade 9 of crossbeam; Pot cover also is provided with reinforced sheet 5 on 11 middle parts.
Described crossbeam 3 two ends are by pin 2 hinged hooks 14, and hook 14 is provided with torsion spring 13 with crossbeam 3 hinged places; Have convex 19 on the hook 14, pot body 18 oral areas have and hook 14 beads that match 20.
Pot cover 11 with periphery that pot body 18 contacts on be provided with annular groove 17, annular groove 17 is embedded in sealing ring 15, to guarantee strict sealing the between pot cover 11 and the pot body 18.
Also be provided with outer cover 21 on the described crossbeam 3, make the pressure cooker outward appearance more attractive in appearance.
Also sound prompt device can be provided with on the pot cover, when desired parameters reaches setting value, voice suggestion can be sent.
When the utility model uses, rotary handle 6 drives top nut 7 rotations, crossbeam 3 is downward thereupon when top nut 7 moves down, linking up with 14 simultaneously also moves downward, link up with 14 convex 19 and will withstand pot cover 11 edges this moment, thereby make torsion that hook 14 overcomes torsion spring 13 open and make the head crotch of hook 14 break away from the constraint of pot body 18 oral area beads 20, thereby pot cover 11 can be opened easily to the outside.When the cooking, pot cover 11 is combined on pot body 18, rotary handle 6 moves upward crossbeam 3, because of linking up with the increase of convex on 14 19 and the Edge Distance of pot cover 11, hook 14 is under the elastic force effect of torsion spring 13, automatically get back to and pot position that the bead 20 of body 18 oral areas matches, hook 14 hooks with a pot alms bowl 18, moves upward owing to crossbeam 3 simultaneously, the internal force that hook 14 produces forces the sealing ring 15 in the pot cover to fit tightly with pot body 18, thereby plays good sealing function.
