Abstract

The utility model relates to a pressure cooker which can enhance biting force in duplication, which is mainly composed of a cooker lid 4, a seal ring 5 and a cooker body 1. The pressure cooker is characterized in that the total projected length of a screw thread-shaped cooker tooth 2 or cover tooth 6 approximately equals to the girth of cooker edge, which makes the cover conjunction of the cooker lid 4 and the cooker body 1 in the screw conjunction structure of full line screw thread. The full line screw thread can be realized by sheathing a pipe-shaped stainless steel pipe wall on the upper end of a barrel shape pan body and a concave and protrude groove which rolls and corresponds in a pitch width at the lower end of the cooker lid.

Description

All fronts biting connecions pressure cooker

The utility model belongs to the culinary cuisine utensil, particularly a kind of thread revolving type pressure cooker.

Pressure cooker on the market is generally aluminum alloy materials and makes now, has occurred the thin-wall stainless steel goods in recent years, and various types of revolving type pressure cooker pot bodies are translated into the plane outside the upper edge, and six five equilibriums form 6 pot teeth simultaneously by dashing 6 breach in outer the reaching then; Translate into punching out 6 corresponding lid teeth in plane in the pot cover outer, promptly pot tooth and Gai Ya are planar shaped, closing Gai Shixian will cover, staggered the interlocking of pot tooth makes and covers tooth and be lower than a pot tooth, rotates pot cover then, make and cover tooth and overlap with a pot tooth from the below and realize interlock, that is to say that the interlock maximum magnitude is 1/2nd (being commonly referred to half line) of pot edge girth, thereby also define the upper limit of snap-in force.Because the interior pressure that 100KPa is born in the requirement of pressure cooker technical standard, when the pot body wall is thick when being 2mm, in order to strengthen pot tooth and Gai Ya intensity, design is that a pot body upper end comprises that the thickness of pot tooth is that 4mm needs to increase by one ironing operation like this, has increased the material consumption simultaneously on technology usually.In addition, owing to be the plane interlock, its sealing sealing ring that places one's entire reliance upon often because of the aging elasticity of sealing ring reduces, causes user's sealing ring of having to frequently change during use.

The purpose of this utility model provides a kind of pressure cooker that can significantly improve the keying strength of pot tooth and Gai Ya under the situation that does not increase wall thickness, perhaps under the situation that keeps pot, the present keying strength of lid tooth, can reduce wall thickness, saves material; In addition, also can reduce elasticity requirement to sealing ring.

The technical solution of the utility model is: by the pressure cooker that pot cover, sealing ring, pot body are formed, the total projection length of the pot tooth of its thread shape or lid tooth is approximately equal to the pot edge girth, makes covering to all fronts thread of pot cover and pot body screw structure.

Utilize pressure cooker provided by the utility model, have following two advantages:

1, owing to realize interlock completely, with respect to original half line occlusion structure, its snap-in force strengthens at double, has improved security.Need not during production to consider to thicken to cover tooth and pot tooth, the pot body wall is thick unanimous between the higher and lower levels, thereby can omit the ironing operation, has also saved material, has reduced production cost;

2, owing to adopt the thread interlock, the spacing between pot, the lid can become with both relative rotation angle, thereby the elasticity of sealing ring is not had specific (special) requirements.Aging or the attenuation such as sealing ring as long as do not rupture, can realize sealing by screwing the pot cover mode, and the user need not often to change sealing ring.

In the accompanying drawing, Fig. 1 is embodiment master's TV structure schematic diagram, and Fig. 2 is the vertical view of pot body among Fig. 1.

Below in conjunction with the manufacturing process that relates to all fronts thread among the embodiment, and with reference to accompanying drawing, the utility model is described in further detail.

One, the pot system is done:

(1), stainless steel (or aluminium) plectane is drawn into pot body 1;

(2), on pot mouth plane circle by six five equilibriums radial cuts from outside to inside, depth of cut be no more than circle wide 1/2nd;

(3), the cutting part punching out is become 6 spiral shell shape pot teeth 2, each pot tooth upper end and adjacent pot tooth lower end basic maintenance under upright projection being joined end to end, also is the girth that spiral shell shape pot tooth total projection length is approximately equal to the pot edge with particular manufacturing craft.The plane is enclosed not, and cutting part is the plane 3 that pad is put sealing ring 5.

Two, pot cover is made:

(1) pound steel (or aluminium) plectane is not drawn into and covers shape;

(2) form pot cover 4 with translating into the plane circle in the bead;

(3) make (2) same procedure radial cuts with above-mentioned pot system;

(4) make (3) same procedure with above-mentioned pot system and be made into corresponding spiral shell female cap tooth 6, the total projection length of lid tooth be approximately equal in the lid along or the girth of pot edge, will cover 4 and execute with a pot body 1 and to close, promptly constitute all fronts interlock.

Above-mentioned pot tooth or lid tooth quantity are not particularly limited in the general knowledge scope, and is also fairly good such as 8 tooth effects in the experiment.

The thickness of the pot body of present embodiment, pot cover, pot tooth, lid tooth is 2mm.

As another embodiment, can in a pitch H width of tubular stainless steel tube wall upper end, roll out several spiral shell shape recessed (protruding) groove and form the pot tooth, then its cover is welded in barrel-shaped pot body upper end, cover tooth with rolling out the formation of corresponding spiral shell shape protruding (recessed) groove in the pitch H width of Stainless steel pot cover lower end, also can reach identical technique effect.

Claims

1, a kind of all fronts biting connecions pressure cooker, form by pot cover (4), sealing ring (5), pot body (1), it is characterized in that the pot tooth (2) of thread shape or the total projection length of lid tooth (6) are approximately equal to the girth of pot edge, make the lid of pot cover (4) and pot body (1) screw structure for the zygonema thread entirely.

2, all fronts as claimed in claim 1 biting connecions pressure cooker, it is characterized in that overlapping and roll out several spiral shell shape recessed (protruding) groove in the pitch H width of the tubular good steel pipe walls upper end that is welded in barrel-shaped pot body upper end and form a pot tooth (2), roll out protruding accordingly (recessed) groove in the pitch H width of Stainless steel pot cover lower end and form and cover tooth (6).
