Abstract

The utility model discloses a pressure cooking kettle, which comprises: a kettle body and a kettle cover; the kettle body is disposed with a flange; the kettle cover is provided with a pressure limiting valve, a opening-stopping valve and at least two radially movable clamp; a turning handle can be turned to drive a pull bar, and the pull bar drive the clamp to open or close the kettle cover. the pull bar comprises an outer pull bar and an inner pull bar; the outer pull bar is hinged to the inner pull bar; the other end of the outer pull bar is fixed to the clamp; the other end of the inner pull bar is driven by the turning handle; and matched limiting mechanisms are disposed on the kettle cover and the outer pull bar. Because the pull bar comprises an outer pull bar and an inner pull bar, and the outer pull bar is hinged to the inner pull bar, the pivoting frictional force at the hinging point and the frictional force at the outer pull bar limiting mechanism is far less than the frictional force in the arc chute or outer cover guiding chute in the background technologies, thereby, the opening and closing operation of the kettle cover is caused easier and the using is more convenient.

Description

Pressure cooker

Technical field:

The utility model relates to a kind of pressure cooker.

Background technology

Existing clamp-type pressure cooker is generally locked pot body and pot cover or release by two clamps." a kind of rotating clamp jaw type pressure cooker " just disclosed for No. 00216103.6 as Chinese patent.In this technical scheme, rotating clamp jaw type pressure cooker comprises: pot body, pot cover, pressure limiting valve assembly, safety valve complement.At least one pair of radially movable clamp of installing of configuration relatively is set on the pot cover, and the control clamp is opened and closed control device, this control device comprise revolve and with revolve the spin-block that matches, have deep-slotted chip breaker on the spin-block, one end of clamp and pull bar is fixed, and the other end of pull bar is by in the deep-slotted chip breaker on the pull bar sleeve embedding spin-block.Be provided with the gathering sill of guaranteeing that pull bar radially moves in the outer cover.It realizes the closure or openness pot cover by clamp moving radially on pot cover.But it has the following disadvantages:

1, owing to guaranteeing that the gathering sill that pull bar radially moves is located in the outer cover, when in use generation was loosening between pot cover and outer cover, it was unreliable to cause clamp to move radially.

2, owing to adopting the one-part form pull bar, spin-block drives pull bar and moves, and pull bar contacts the resistance that produces with gathering sill forces pull bar to move radially, and makes the unlatching of clamp and closed procedure require great effort, and uses inconvenient.

3, for to make gathering sill enough intensity be arranged to bear the friction of pull bar, the outer cover of tape guide groove is generally made with metal material, makes above-mentioned pressure cooker manufacturing cost height.

Summary of the invention:

The purpose of this utility model is: the pressure cooker that a kind of clamp mobile working is reliable, operation is light, manufacturing cost is relatively low is provided.

The utility model is achieved through the following technical solutions:

A kind of pressure cooker comprises: pot body and pot cover, and pot body oral area is provided with flange, and pot cover is provided with pressure limiting valve, stopping valve and at least two clamps that can move radially, and revolves rotation is driven pull bar, and pull bar drives clamp to open or to cover pot cover; It is characterized in that: described pull bar comprises outside link and draw-in bar, and outside link and draw-in bar are hinged, and the outside link other end and clamp are fixed, and the draw-in bar other end is by revolving driving, and pot cover and outside link are provided with the position-limit mechanism that matches.

The course of work of the present utility model is as follows: when opening pot cover, handle is revolved in rotation, revolve rotation is driven draw-in bar, draw-in bar promotes outside link, because outside link is hinged with draw-in bar and pot cover and outside link are provided with the position-limit mechanism that matches, thereby clamp is radially outwards moved, realize opening pot cover.Backward rotation is revolved then closing the lid operation.

Advantage of the present utility model is: because pot cover and outside link are provided with the position-limit mechanism that matches, it is very reliable that it can make clamp move radially, and reduces the manufacturing cost of pressure cooker simultaneously.Because pull bar comprises outside link and draw-in bar, outside link and draw-in bar are hinged, the frictional force at the rotation friction of this pin joint and outside link position-limit mechanism place will be far below the frictional force of gathering sill in deep-slotted chip breaker in the background technology and the outer cover, make that the unlatching and the closed procedure of the utility model pot cover are very light, use more convenient.

In the utility model, the described draw-in bar other end is hinged with the rotatable lamella of band joint pin, revolves being provided with the joint pin patchhole.Adopt said structure with draw-in bar with revolve linking to each other, it is simple in structure, simultaneously, guarantees to revolve reliable transmission between handle and draw-in bar.

In the utility model, described at least one outside link is provided with the stopping valve perforate, and pot cover is provided with the pressure limiting valve perforate.Making pressure cooker of the present utility model have safety only opens and the pressure limiting function.

In the utility model, described position-limit mechanism comprises: be fixed in limited block and the elongated hole of being located on the outside link on the pot cover.Position-limit mechanism adopts said structure, and it is simple in structure, low cost of manufacture, and can limit moving radially of outside link and clamp reliably, guarantee the pot cover reliable operation.

In the utility model, described limited block is the two cylindrical limited posts that are welded on the pot cover.It can guarantee to reduce the friction between outside link and limited post under the spacing reliable situation.

Fig. 3 is the utility model status architecture schematic diagram (remove revolve) of uncapping.

Fig. 4 is that the utility model revolves bottom schematic view.

The specific embodiment:

In conjunction with Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: a kind of pressure cooker of present embodiment, comprise: pot body 1 and pot cover 2, pot body oral area is provided with flange, pot cover is provided with pressure limiting valve 3, stopping valve 4 and at least two clamps that can move radially 5, revolve 6 rotation drive pull bars, pull bar drives clamp to open or to cover pot cover.Pull bar comprises outside link 7 and draw-in bar 8, and outside link 7 is hinged with draw-in bar 8, and outside link 7 other ends and clamp 5 are fixing, and draw-in bar 8 other ends are by revolving 6 drives, and pot cover 2 and outside link 7 are provided with the position-limit mechanism that matches.Outside link 7 is provided with a stopping valve perforate 9, and pot cover is provided with pressure limiting valve perforate 10.

Draw-in bar 8 other ends are hinged with the rotatable lamella 12 of band joint pin 11, revolve being provided with joint pin patchhole 13.Position-limit mechanism comprises: be fixed in limited block and the elongated hole of being located on the outside link 14 on the pot cover.Limited block is the two cylindrical limited posts 15 that are welded on the pot cover.

Because pot cover and outside link are provided with the position-limit mechanism that matches, it is very reliable that it can make clamp move radially, and reduce the friction between outside link and limited post, reduces the manufacturing cost of pressure cooker.Because pull bar comprises outside link and draw-in bar, outside link and draw-in bar are hinged, the frictional force at the rotation friction of this pin joint and outside link position-limit mechanism place will be far below the frictional force of gathering sill in deep-slotted chip breaker in the background technology and the outer cover, make that the unlatching and the closed procedure of the utility model pot cover are very light, use more convenient.And draw-in bar and the syndeton of revolving between handle are simple, reliable transmission.
