Description

Metal pan combines the combined cover of usefulness with lever

The utility model relates to the parts of cooking appliance, particularly a kind of cover in conjunction with metal pan and its lever.

The combined cover structure of metal pan of commonly using and lever, can consult Fig. 1 illustrates, it is to be plane 101 by an end, and hold sheet metal to be bent into hollow form in addition with a turnover plane 102, after the bending, plane 101 can fall to being located at the turnover plane 102 on, again with mash welder 103 with the two solid welding, so this structure can cause following drawback:

A, because of being by mash welder 103 solid weldings, so the surface can stay pad, the existing property of the outer existing U.S. of influence.

When B, welding, must be earlier with plane 101 and turnover plane 102 pressings row welding again, so time-consuming taking a lot of work.

C, plane 101 is mat spot welding seam with the abutment on turnover plane 102, so the quality of welding directly influences service life, thus must give special heed to when carrying out spot welding, so can cause the waste in man-hour.

Intrinsic above-mentioned disadvantages, so people's another kind of structure of redeveloping out is arranged, (as shown in Figure 2) it mainly is to be bent into hollow form by a sheet metal, and several cards 104 are arranged in the outside projection of two binding end end walls of this sheet metal, this card 104 be expansion section 105 than outboard end, nearly Inner end then is skinny 106, the card 104 of two binding ends is staggered arrangement, and 104 set draw-in groove 107 shapes of a binding end card and size equal another binding end the shape and the size of corresponding card, mutually combine with engaging of draw-in groove 107 in order to do two binding end cards 104.

Only look into this structure, still have following drawback:

A, because of it is that the card 104 and the draw-in groove 107 of mat two binding ends mutually combines, so in conjunction with the time must be quite accurate, just can make card 104 and draw-in groove 107 finish combination, oppose time-consuming taking a lot of work.

B, because of the adhesion of the card 104 of its two binding end, what be mat expansion section 105 with skinny 106 is big or small very nearly the same, so the intensity that is produced is little, so lack service life.

The purpose of this utility model is a kind of metal pan that overcomes the above-mentioned shortcoming of prior art of design combines usefulness with lever a combined cover, and it is smooth that it has appearance, and the life-span is long, the characteristics that cost is low.

Above-mentioned purpose of the present utility model can adopt following technical scheme to realize.The strip sheet metal that is had the circular arc opening by a side bends the metal pan that forms combines usefulness with lever combined cover, and its architectural feature is that this belongs to sheet entirely and is divided into a long end and a short end with respect to its circular arc open centre; These long and short two ends are formed with the male and female fastening structure that fastens mutually when supplying this sheet metal to be bent into hollow square respectively.

According to the embodiment of the utility model, this male and female fastening structure is included in these length end outside two ends and laterally is convexly equipped with two projections, and this two projection and this length end joint are established two geosutures, and offer two side's openings in two outside appropriate locations of this weak point end.

According to another embodiment of the utility model, this male and female buckle structure is included in each perpendicular projection that is provided with of two outsides of this weak point end, and this long end end place forms a turnover plane, and its turnover is in its two outside and respectively is provided with a square hole.

According to the another embodiment of the utility model, this male and female fastening structure is included in to be established two and is and crushes the not circular arc lug of fracture on this weak point end, and the turnover plane that this length holds place to establish is provided with two corresponding square open-works; In addition, this circular arc lug can also be by superimposed plane above two square open-works on the turnover plane through being stamped to form.

Advantage of the present utility model:

A, back its outward appearance of combination are plane, make the people cannot see binding site, so more attractive in appearance on outer showing.

The method of B, its combination is all the manner of mutual hook or anti-hook, and puzzlement tight and that nothing gets loose, enemy's long service life.

C, its main body system utilize easy male and female to cooperate, and the mode of combination is simple and combination fast is fit to a large amount of productions, so the man-hour that can reduce cost and make up.

D, it can be because of different moulds, and do different engagement states, richer variability and the expense that can save the exploitation new die again.
