Abstract
The utility model relates to a pressure automatic linking safety device for a pressure cooker, which is composed of an indicating valve, a wobble plate, a cam pendulous axis, a fixing sleeve, a reset spring, a spring hook, a handle, etc. The indicating valve and pendulous rod components are arranged in a cooker lid and an upper handle. Through mutual linkage between the indicating valve and the pendulous rod components, accidents caused by the reason that the cooker lid is not fastened in place or the cooker lid is forced to be opened as the pressure cooker still has air pressure can be avoided. The utility model has the advantages of reasonable design, simple production process, low cost, good sealing performance, compact structure, firm and durable structure, safe and convenient operation, etc.
Description
The utility model belongs to the automatic chain safety device of a kind of pressure cooker air pressure.
At present, the chain safety device of pressure cooker open and close cover has various, for example patent 96236662.5 pressure cooker foolproof apparatus, patent 96217223.5 pressure cooker cover closing/opening safety devices, patent 95246106.4 pressure cooker safety interlocks etc., all can utilize interlock to control the interior air pressure of pressure cooker, safety has had assurance, but fasten not in place with pot cover sometimes or pot in also have air pressure and when the maloperation phenomenon such as uncapping by force, the accident that just can not prevent takes place, in addition, existing safety device is hand switch, and operation is convenient inadequately.
The purpose of this utility model provides the automatic chain safety device of a kind of pressure cooker air pressure, be prone to the reason of accident at pressure cooker, ad hoc air pressure indicator valve, pot cover fastens the indication that all has not in place, informs that the user closes lid again, when remaining certain air pressure in the pot, be in latched position, pot cover can not draw away, and has overcome the insecurity of uncapping by force and bringing, and the accident that prevents takes place.This device is not with any hand switch, fully by handle control, has solved the problem of inconvenient operation.
The utility model is made up of indicator valve, oscillating deck, cam balance staff, fixed cover, back-moving spring, spring and handle etc., indicator valve (18) is made up of valve rod, valve body, fastening glue bowl, valve rod (1) is a hollow rod member with the level, two ends respectively are drilled with 2 holes (12) up and down, fastening glue bowl (3) is arranged at the bottom, valve rod (1) is contained in the valve body (2) of hollow body, and valve body (2) riveted joint is fastened on the pot cover (4); Oscillating deck (5) one ends and valve rod (1) aligned position have a semi-circular hole (14), and the other end has the rectangular groove of a flange (17), and there is a hole at the middle part, puts fixed cover (7), and countersunk head screw (8) is fixed on fixed cover (7) on the upper handle (9); Oscillating deck (5) is slidingly connected with cam balance staff (6) upper end swing arm (19), and cam balance staff (6) stage casing connects with back-moving spring (10), and the lower end is provided with cam (13); Upper handle (9) middle part is provided with upper and lower balance staff seat (15,16), is used for fixing cam balance staff (11), and an end of back-moving spring (10) is enclosed within fixing spring and colludes on (11), and the other end is enclosed within on the spring in cam balance staff (6) stage casing.
The utility model mainly is the improvement to pressure cooker upper handle structure, indicator valve is set in pot cover and a fixing point is set in upper handle, utilize concavo-convex effect with pot body tooth, swing displacement with the cam balance staff, oscillating deck is given in transmission, oscillating deck is produced swing, reach the purpose of cover closing and opening safety device, can prevent from effectively to remain air pressure in not in place or the pot and uncap maloperation by force and the accident that causes when pot cover fastens.It is reasonable in design, and production technology is simple, good airproof performance, and compact conformation, sturdy and durable, easy and safe to operate.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model closes and covers view;
Fig. 3 is not oscillating deck schematic diagram during folding of the utility model pot cover;
Fig. 4 is that the utility model closes lid oscillating deck schematic diagram when not in place.
Below in conjunction with accompanying drawing the utility model is elaborated:
As shown in Figure 1, indicator valve is made up of valve rod, valve body, fastening glue bowl, valve rod (1) and the hollow rod member of a band step, two ends respectively are drilled with the pore (12) of 2 Φ 2 up and down, the bottom has fastening glue bowl (3) to be contained in the valve rod lower end, seals, and valve body (2) riveted joint is fastened on the pot cover (4).Oscillating deck (5) one ends and valve rod (1) aligned position mutually dash the semi-circular hole (14) that a Φ 13 is arranged, the other end dashes the rectangular groove (17) of one 6 * 15 flange, be slidingly connected with cam balance staff (6) upper end swing arm (19), the middle part dashes Φ 9 holes, put fixed cover (7), and can swing, with countersunk head screw (8) fixed cover (7) is fixed on the upper handle (9), cam balance staff (6) stage casing connects with back-moving spring (10), the lower end is provided with cam (13), can the oscillating deck (5) of connection be produced swing with the displacement that swings back and forth of pot body tooth platform.Upper handle (9) middle part is provided with up and down balance staff seat (15,16) stationary cam balance staffs (6) and fixing spring and colludes (11) and do that cam balance staff (6) connects back-moving spring (10) and oscillating deck (5) is used.
Through assembling and setting repeatedly, the semicircle orifice (14) of oscillating deck (5) is failure to actuate and is aligned with valve rod (1) when pot cover (4) inactive state, valve rod (1) can slide up and down, when working pressure pot pot cover is not incorporated into, pot body tooth ledge has been turned right the cam (13) of cam balance staff (6) and has been pressed interlock to make oscillating deck (5) swing of turning left be in pore (12) the discharge gas that valve rod (1) top can not go up valve rod (1) pass through valve rod (1) to the greatest extent fully when covering because of closing, make a pot internal gas pressure be not more than 5KPa, thereby play to close and cover safety effect, avoid not blowing up the situation that pot cover hurts sb.'s feelings and taking place because of lid is incorporated into the position.When pot cover is incorporated into fully, the cam (13) of cam balance staff (6) is fully along at the bottom of pot body tooth slides into tooth the time, oscillating deck (5) is under the effect of back-moving spring (10), cam balance staff (6) drives oscillating deck (5), semi-circular hole (14) aligns with valve rod (1), the crack is 2.5MM between the semi-circular hole (14) of valve rod (1) and oscillating deck (5), valve rod (1) can be to rising, and under the effect of air pressure to rising to sealing, gas has been arranged in cooked back of food as the pot, valve rod (1) can be uncapped voluntarily owing to the weight of self falls.As there is residual air, valve rod (1) can't fall owing to gas pressure, this moment is as uncapping, because cam balance staff (6) is under the connection swing effect at the bottom of the pot body tooth, make oscillating deck (5) produce swing from left to right, but do not fall because of valve rod (1) this moment, and make oscillating deck (5) can't swing and lock to the right, therefore can't uncap, play safety effect.
Available metal materials processings such as valve rod, valve body, oscillating deck, cam balance staff, fixed cover, spring in the utility model, upper handle can form with the phenoplasts compacting, and fastening glue bowl, countersunk head screw, back-moving spring all can be bought, and press the figure process and assemble and get final product.
