Description
Technical field
The utility model relates to a kind of pressure cooker, specifically relates to the safe locking device of pressure cooker.
Background technology
Pressure cooker belongs to the daily life cooker, the locking mode of present pressure cooker cover mainly adopts the rotation pot cover, the groove chucking of the interior scotch of pot cover and sealing ring and stay-warm case is fixed, after its shortcoming is locking, locked easily, and when pot cover fasten not in place or pot in when having remained air pressure, and the maloperation of uncapping by force easily causes the accident, and has potential safety hazard.Improved safe locking device is also arranged, as application number is 98233741, the applying date is on March 5th, 1998, denomination of invention is the patent of the automatic chain safety device of pressure cooker air pressure, form by indicator valve, oscillating deck, cam balance staff, fixed cover, back-moving spring, spring and handle etc., it is characterized in that: indicator valve is made up of valve rod, valve body, fastening glue bowl, valve rod is a hollow rod member with the level, two ends respectively are drilled with 2 holes up and down, the fastening glue bowl is arranged at the bottom, valve rod is contained in the valve body of hollow body, and the valve body riveted joint is fastened on the pot cover; Oscillating deck one end and valve rod aligned position have a semi-circular hole, and the other end has the rectangular groove of a flange, and there is a hole at the middle part, puts fixed cover, and countersunk head screw is fixed on fixed cover on the upper handle; Oscillating deck and the upper end swing arm of cam balance staff are slidingly connected, and cam balance staff stage casing connects with back-moving spring, and the lower end is provided with cam; The upper handle middle part is provided with upper and lower balance staff seat, is used for fixing the cam balance staff, and an end of back-moving spring is enclosed within fixing spring and colludes, and the other end is enclosed within on the spring in cam balance staff stage casing.This patent is improved the usual pressure pot exactly, indicator valve and oscillating bar assembly are set in pot cover and upper handle, by indicator valve and the mutual interlock of oscillating bar assembly, preventing that pot cover from fastening uncaps not tight or improper opportunity, its improvement has certain effect, but its complex structure is changed the cost height, is unfavorable for producing the needs of popularization.
Summary of the invention
The purpose of this utility model be exactly provide in order to solve above-mentioned deficiency a kind of simple in structure, change low, the safer practicality of cost, can cover the safe locking device of tight pressure cooker automatically.
The utility model is realized above-mentioned purpose by following technical proposals:
The utility model is arranged between pot cover and the stay-warm case, is made of the fluctuating hook groove that is arranged on projection piece on the pot cover, is arranged on stay-warm case; When covering, the projection piece on the pot cover edge is inserted in the fluctuating hook groove on the stay-warm case; Described fluctuating hook groove is " √ " shape; Described projection piece is corresponding with fluctuating hook groove to be provided with several rightly, becomes the equal circumference setting.
Advantage of the present utility model is: 1, by improving the pot cover and the stay-warm case of usual pressure pot, it is low to change cost; 2, the projection piece on the pot cover places in the fluctuating hook groove on the stay-warm case and can slide up and down, and is simple and practical, is convenient to promote; 3, when producing pressure in the pot, the projection piece jack-up fluctuating hook groove end of pot cover, pot cover can not turn round; When pot cover buckles when incorrect, when in the pot pressure being arranged, pot cover can slide to the locking closure position automatically, or skids off stay-warm case along fluctuating hook groove, makes in the pot and can not produce pressure, guarantees safe in utilization.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments
Fig. 1 is the utility model pot cover front view;
Fig. 2 is the utility model pot cover left view;
Fig. 3 is the front view of the utility model pot body and stay-warm case;
Fig. 4-8 is the local user mode procedure chart of the utility model embodiment.
Specific embodiment
As Fig. 1, Fig. 2, Fig. 3, the utility model is arranged between pot cover 1 and the stay-warm case 3 by improving the usual pressure pot, is made of the fluctuating hook groove 4 that is arranged on projection piece 2 on the pot cover 1, is arranged on stay-warm case 3; Projection piece 2 is arranged on inboard, pot cover edge, its diameter is slightly less than the width of fluctuating hook groove 4, fluctuating hook groove 4 is arranged on the outside of stay-warm case, be about " √ " shape, return till the chimoto of " √ ", projection piece 2 on the pot cover 1 is inserted in the fluctuating hook groove 4 on the stay-warm case 3, and the pot cover 1 that turns clockwise is a lockable.
As shown in Figure 4, the fluctuating hook groove 4 that pot cover 1 is aimed at stay-warm case 3 is put into, because the gravity effect, the projection piece 2 on the pot cover 1 slips into along the hypotenuse of fluctuating hook groove 4, as shown in Figure 5, when in the pot pressure being arranged, projection piece 2 on the pot cover 1 can slide to the locking closure position automatically, or skids off stay-warm case 3 along the hypotenuse of fluctuating hook groove 4, makes in the pot and can not produce pressure, guarantee safe in utilizationly, Fig. 6 slides into the state of fluctuating hook groove at 4 ends for pot cover 1; When producing pressure in the pot, projection piece 2 jack-up of pot cover 1 are to the non-return position of fluctuating hook groove 4, and this moment, pot cover 1 can not turn round, as Fig. 7; When not having pressure in the pot, pot cover 1 resets, and rotate counterclockwise pot cover 1 and can open pot cover 1 this moment, shown in Figure 8.
Described projection piece 2 is provided with 3 pairs with fluctuating hook groove 4, becomes the equal circumference setting; Described projection piece 2 also can be arranged on the outside portion of stay-warm case, and fluctuating hook groove 4 adapts with projection piece 2 can be arranged on the pot cover inboard.
