Abstract
The utility model relates to a pressure cooker without a sealing ring. The original soviet union pressure cooker adopts safety rod pressure which can guarantee the safety of the pressure cooker, but the cooler cover is difficult to open. The original pressure cooker is sealed by a sealing ring, and because the sealing ring is easy to age, the periodic replacement becomes to a problem. The pressure cooker without a sealing ring of the utility model comprises a cooker body 1 at the upper end of which a cooker cover 3 is arranged. A pressure regulating valve 19 and a safety valve 18 are arranged at the upper end of the cooker cover 3, the external conical end face 2 at the upper end of the cooker cover 3 and the internal conical end face 4 at the upper end of the cooker body 1 are pressed firmly, a central axis 5 is fixedly connected to the top of the cooker cover 3 by the nut 6, and an eccentric wheel 7 which is connected to the handle 10 by the operating lever 9 is arranged on the central axis 5. A catch plate ring 12 and a handle 13 are fixed on the external end face of the cooker body 1 symmetrically, and a safe bar 11 on the top of which a handle 8 is provided is arranged in the catch plate ring 12. The utility model is used in the daily life.
Description
Technical field: the utility model relates to a kind of novel no sealing ring pressure cooker.
Background technology: former the earliest in Soviet Union's pressure cooker, sharpest edges are to adopt safety pole to compress, abandoned a rotary locking structure, can guarantee that pressure cooker is perfectly safe, pressure regulator valve and safety valve under normal circumstances can be guaranteed safety, can superpressure, can not complain and quarrel loudly, once two valves all block, and the pot internal gas pressure still constantly rises, when air pressure reached certain numerical value, the safe thick stick that will bend lifted a little with pot cover, exhaust then, when air pressure just often, it can utilize metallic elastic, sealing resets once again, therefore can guarantee that pressure cooker is perfectly safe, but because adopt the leading screw hand to turn round compressing structure, because the resistance that self-locking performance had of screw is too big, the lid pot, it is all very hard to boil, especially women and old man use and have any problem, and now all withdraw from the market.The pressure cooker that generally uses has rubber seal at present, its sealing ring is easily aging, need periodic replacement, make troubles to use, and pot cover and pot body adopt plane spiral cover compressing structure, and pressure regulator valve and safety valve are once all be blocked after death the continuation supercharging, have only road of blast step-down, make the security of pressure cooker be difficult to ensure.
Summary of the invention: the purpose of this utility model provides a kind of simple in structure, and is safe in utilization, reliable, the novel no sealing ring pressure cooker of good sealing effect.
Above-mentioned purpose realizes by following technical scheme:
Novel no sealing ring pressure cooker, its composition comprises: the pot body, pot cover is equipped with in described pot body upper end, pressure regulator valve and safety valve are equipped with in described pot cover upper end, described pot cover upper end outer cone end face and described pot body upper end female cone end face compress, central shaft and fixedly connected with nut is equipped with on described pot cover top, eccentric wheel is housed on the described central shaft and is connected with handle by actuating linkage, symmetry fixedly is equipped with clamp ring and handle on the external end face of described pot, in the described clamp ring safe thick stick is housed, handle is equipped with on the top of described safe thick stick.
Above-mentioned novel no sealing ring pressure cooker is equipped with support in the described pot body, and the pot connection is housed on the described support.
Above-mentioned novel no sealing ring pressure cooker, described pot body is a drum shape.
Above-mentioned novel no sealing ring pressure cooker, described pot cover is the hemispherical discs shape, described handle is spherical handle.
This technical scheme has following beneficial effect:
1. novel no sealing ring pressure cooker of the present utility model, be on the basis of the usual pressure pot of public use, retrofit for the second time, cancelled sealing ring, break no sealing ring and then be not called the tradition of pressure vessel, use gapless taper fit, replace the just flat fastening with sealing ring, its method is in the oral area junction of pot body and pot cover pot body oral area to be processed internal conical surface, and the oral area of pot cover processes outer conical surface, borrow hold-down mechanism, eccentric rotation pressure reaches outer conical surface and internal conical surface and closely cooperates, and forms the totally-enclosed novel pressure cooker that does not leak, its sealing effectiveness is better than the sealing effectiveness that sealing ring is arranged, really accomplished more sealing, it is more lasting to use, and uses this product can save sealing rubber ring, also saved and changed the trouble that sealing ring brings, and safety is guaranteed.
2. there is not the sealing ring pressure cooker and is " with awl, side, tiltedly just replacing, flat, straight " Machine Design theory, its design philosophy have in theory a big new breakthrough (with awl, side, tiltedly just replacing, flat, straight " a big new breakthrough of Machine Design thought is published on 2002 the tenth second phases of Ministry of Machine-Building Industry's Machine Design); this world breaks through; be equally applicable to hydraulic press, hydraulic press, air compressor, steam engine, boiler, aircraft, motorcycle moving (buffer), also be applicable to the transformation (comprising track for a train, city underground, light rail construction etc.) of diel.
3. this product is earlier pot cover to be covered into a pot body upper end in use, after inside and outside circular cone aligns, safe thick stick is changed in the clamp ring, central shaft is fixed on the top of pot cover with cap nut, again eccentric wheel is fixed on the central shaft, safe thick stick is enclosed within on the central shaft, fixes, whole retaining mechanism is become one with the ball-type handle, the hand balanced handle turns to the right side by the center, eccentric wheel is rotated press pot cover from low to high, outer cone and female cone are reached closely cooperate, and lock constant, thereby formed totally-enclosed, leak free pressure vessel had not both had the pressure cooker of sealing ring, had guaranteed safe in utilization.
4. this product adopts safe thick stick as hold-down mechanism, has abandoned the disposable locking of cap-rotating type mechanism, thus can guarantee to be perfectly safe, thus thoroughly eradicated the hidden danger that pressure cooker is complained and quarrel loudly easily.
5. because pot body and pot cover have adopted gapless cone to cooperate, replaced the present world, domestic generally use just, reef knot closes, promptly cancelled sealing rubber ring, the advantage that cone cooperates is not have the gap, automatic centering, dereism, self-locking performance are all very good, add that the hold-down mechanism energy pressurize of being made up of central shaft, nut, actuating linkage, eccentric wheel, pot cover, handle and spherical handle is tightly reliable, and air-tightness is good.
6. the balanced handle of this product drives eccentric wheel by actuating linkage and forwards high convex surface to by low concave surface and press pot cover to carry out compacting to lock, replaced the hand button with lever, overcome existing pressure cooker and under high pressure reversed the hard slow again shortcoming of screw rod, appearance design is also more perfect, and pressing is faster, more save labour.
Description of drawings: accompanying drawing 1 is a structural representation of the present utility model.
