The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1 to Figure 3, the aluminium matter High Temperature High Pressure can easy-open end of the utility model embodiment comprises and covers frame 1, closure plate 2 and draw ring 3, wherein, lid frame 1 is for being fixed on vessel port, play the effect being connected and fixed, distance H between lid frame 1 top and the bottom surface of transition scrobicular ring 22 is 5.2 millimeters, can certainly be the arbitrary numerical value between 3 millimeters to 8 millimeters, vertical distance between lid frame 1 and closure plate 2 is unlikely to oversize like this, effectively raises the non-deformability of lid; The bottom surface of lid frame 1 is provided with annular slot, and lid frame 1 is fixed in vessel port by annular slot.
The thickness d of aluminum closure plate 2 is 0.5 millimeter, closure plate 2 is connected with lid frame 1, can is played to sealing function, because can need to be produced under the environment of High Temperature High Pressure, if lid adopts existing structure and manufactures with aluminium, can cause lid rigidity, the requirement of hardness out of reach, lid easily produces distortion, there is rough phenomenon, lid even can be given and damage by high pressure steam, cause poor sealing, outward appearance is not attractive in appearance yet, for fear of this problem, closure plate 2 is formed and connects bulge loop 21 to center of circle direction successively bending by cylindrical, transition scrobicular ring 22, strengthen bulge loop 23 and be positioned at recessed 24 of home position, adopt this structure, strengthening bulge loop 23 can effectively increase the strength and stiffness of lid, preferably, connect between bulge loop 21 and transition scrobicular ring 22, between transition scrobicular ring 22 and reinforcement bulge loop 23, strengthen bulge loop 23 with recessed 24 between all by an inclined-plane 25, be connected, inclined-plane 25 guarantees that bending part seamlessly transits, avoid producing stress, the surperficial retractility of closure plate 2 is better, preferably, the width L on inclined-plane 25 is 0.8 millimeter, as shown in Figure 2, the internal diameter R that connects bulge loop 21 is 1.8:1 with the ratio of strengthening the internal diameter r of bulge loop 23, the width k that strengthens bulge loop 23 is 0.2:1 with the ratio that is connected the internal diameter R of bulge loop 21.
Draw ring 3 is riveted together with this closure plate 2, and be provided with line of weakness 4 between closure plate 2 and lid frame 1, draw ring 3 and the contiguous line of weakness 4 in the interconnective position of closure plate 2, like this when opening easy open cover, line of weakness 4 generation cracks, place a little less than closure plate 2 and the shearing stress that covers frame 1 concentrate on thin thickness, thereby it is separated to force closure plate 2 and lid frame 1 to be torn between the two, draw ring 3 is riveted together with this closure plate 2, and draw ring 3 adopts tin-plate material to make, hardness is higher, what the degree of depth of line of weakness 4 can be portrayed like this is more shallow, increase and connect wall thickness, rigidity and the hardness of closure plate 2 have been improved further.
The top of line of weakness 4 is provided with from lid frame 1 stretches out, safe edge 11 along line of weakness 4 trends, horizontal throw between line of weakness 4 and safe edge 11 edges is between 0 to 0.5 millimeter, safe edge 11 comprises along lid frame 1 inwall to horizontally extending the first connecting strap 111 of internal tank, the end face of the first connecting strap 111 is provided with towards container inner wall direction and is tilted to the second connecting strap 112 of downward-extension, the lower end of the second connecting strap 112 is provided with towards horizontally extending the 3rd connecting strap 113 of internal tank, closure plate 2 is connected mutually with the 3rd connecting strap 113, horizontal throw between line of weakness 4 and the first connecting strap 111 end faces is between 0 to 0.5 millimeter.Described the first connecting strap 111, the second connecting strap 112 and the 3rd connecting strap 113 interconnect and are integral, formation is the cross-sectional plane of " Z " shape, be further used as preferred embodiment, the cross-sectional plane 114 of the coupling end of the first connecting strap 111 and the second connecting strap 112 is arc-shaped curved surface, so in use, the edge of safe edge 11 is rounder and more smooth, does not hinder hand.
In actual production, easy open cover of the present utility model adopts aluminum material to replace traditional tin-plate material, lid frame 1 and closure plate 2 be one-body molded punching press out, most of easy open covers are all circular, therefore can utilize metal die stamped.Because the performances such as the hardness of aluminum alloy, rigidity are all low than tin-plate, but the utility model adopts and is provided with the closure plate structure of strengthening bulge loop 23, not only good rigidity, non-deformability is strong, and lightweight, can not get rusty, can meet equally the encapsulation requirement that internal tank produces larger pressure.
The above is the specific embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
