Description

Ring-fastening bolt for household pressure cooker

The utility model is used for family's cooking utensils, particularly a kind of collar pin device that can prevent the gas leakage of family expenses seal ring of pressure cooker.At present, the family expenses pressure cooker has entered huge numbers of families, has high temperature, saves time, advantage such as energy-conservation.Especially its 120 ℃ of high temperature (can stew meat, bone mashed in short-term) are that other cooker institute can't replace, and are subjected to user's welcome especially.These advantages of pressure cooker mainly are not allow the steam gas leakage that leaks guarantee by the sealing ring of making of rubber.But first wife's the rubber seal life-span is short, usually use some months and will modification shrink gas leakage, must change at any time, various each manufacturer production of sealing ring accessory reason of market sale now, its thickness specification disunity, appropriate degree does not guarantee, often short supply again, and its result of use of pressure cooker of gas leakage is not as good as common aluminium pan.In order to prolong the service life of sealing ring, there is the people to adopt two sealing rings simultaneously, one is specifically designed to the oiliness food that boils, and another is specifically designed to cooking rice.When temperature is low in the winter time, for fear of gas leakage, also must sealing ring be scalded with boiling water before the use, and then put pot cover into and use, the purpose of scalding circle is to allow the sealing ring expanded by heating seal.Above-mentioned two kinds of usings method of improving sealing rings, though can its life-span of proper extension and improve its serviceability, when sealing ring further shrink leak gas after or of no avail.

Task of the present utility model is that one of design can be adjusted the sealing ring tight ness rating at any time, prevents the collar pin device of pressure cooker gas leakage, makes sealing ring never leak gas, and the life-span improves greatly, needn't change circle.

Task of the present utility model is achieved in that this collar bolt is made up of lower chuck 4, upper grip 3 and the nut bolt that has been used for pressuring action that links to each other with them, wherein the bottom of lower chuck 4 is hook shape, when compressing use, lower chuck 4 contacts with pot cover outer upper surface 5 with pot body outer bottom surface 6 respectively with upper grip 3.

Below in conjunction with drawings and Examples the utility model is done to describe further.

Fig. 1 is the overall structure schematic diagram of first kind of embodiment of the utility model.

Fig. 2 is that the collar bolt compresses the schematic diagram when using on pressure cooker.

Digital declaration of will is as follows among the figure: 1, and wing bolt, 2, nut, 3, upper grip, 4, lower chuck, 5, pot cover outer upper surface, 6, pot body outer bottom surface.

See figures.1.and.2, wherein the bottom of lower chuck 4 is hook shape, and purpose is to block a pot body outer bottom surface 6 in use better, and the top of lower chuck 4 is connected with a nut 2, and nut 2 can fitly be made with lower chuck 4, also can the split manufacturing.Upper grip 3 is connected with wing bolt 1, and both also can fitly make or the split manufacturing, and during use, upper grip 3 contacts with pot cover outer upper surface 5, and in order to reduce wear, the contact point of last lower chuck should be made the blunt surface of circle.

Fig. 3 is the overall structure schematic diagram of second kind of embodiment of the utility model.

Fig. 4 is the schematic diagram of extraordinary fastening bolt 7.

With reference to Fig. 3 and Fig. 4, the upper grip 3 of Tape movement arm and lower chuck 4 are sleeved on the bolt 7, and upper grip 3 can axially move freely along bolt 7 by transfer arm.Can adorn a spring 10 between upper grip 3 and the lower chuck 4, lower chuck 4 is strutted the bottom that is positioned at bolt 7 under the effect of spring force.For lower chuck is freely rotated around bolt 7, the cross section of bolt 7 Lower Halves can be made into regular polygon as making square or circle and lack or the shape of band keyway, and corresponding with the size shape of connecting hole on the last lower chuck transfer arm.Wing nut 8 is positioned at the first half of bolt 7, between upper grip 3 and wing nut 8 sleeve 9 can be housed, and purpose is in order to adjust the stroke distances of wing nut 8 more easily.

When using the utility model collar bolt, as long as at will put up (see figure 2) on the both sides of pot cover with loading onto after estimating centering with two collar bolts, hand-tight make-up wing bolt 1 or wing nut 8 are screwed onto the feel feel and have covered tightly and get final product.The utility model can be vast family and overcomes seal ring of pressure cooker with a difficult problem of promptly leaking gas for a long time, uses product of the present invention can adjust the tight ness rating of rubber seal at any time, and pressure cooker is never leaked gas, and as long as first wife's circle can use for a long time and needn't change circle.
