Abstract
The utility model relates to a safety device for a pressure cooker, particularly the technical field of a self-locking mechanism for safely using a pressure cooker. The utility model is characterized in that an eccentric wheel self-locking mechanism is arranged on an upper handle of the pressure cooker; the mechanism is formed by that a sliding slot of the upper handle is provided with a pushing plate 10 which can be connected with an ejection plate 6 through a shaft hole, simultaneously, an eccentric wheel 9 is fixed on the upper handle 11 through a shaft pin 7 and is connected with the ejection plate 6 through a connecting component 13, and a torsion spring 8 is arranged between the eccentric wheel 9 and the shaft pin 7. A proper position of the upper handle 11 of a pressure cooker cover is provided with a thrust valve rod 3 which can move up and down. The technology has the advantages that of novel design, compact structure, self locking function, explosion preventing function by releasing steam and reducing pressure, low cost, high reliability and convenient operation.
Description
The utility model is that pressure cooker uses safeties, the self-locking mechanism technical field of security insurance when relating in particular to the pressure cooker switching.
When the improper use, occur dangerously for fear of pressure cooker,, a collection of patented technology occurred as explosion phenomenon.As the patent No. is that 94206278.7 Chinese patent pressure cooker uses safeties, a kind of safe self-locking mechanism that opens and closes is provided, when its shortcoming is used, need upper and lower handle to cooperate, fragile, or block can not locking phenomenon, structure is relative complex also, as the patent No. is 93230335.8 Chinese patent pressure cooker open and close cover safety control, and its shortcoming is a complex structure, the pressure limiting function of losing heart.
The utility model purpose is to provide a kind of eccentric wheel type to have the self-locking good reliability, and has the pressure cooker of the pressure limiting function of further losing heart to use safeties.
It is to realize like this that pressure cooker of the present utility model uses the technical scheme of safeties.It comprises push pedal, spring, thrust valve rod, upper and lower handle, pot cover, has an eccentric wheel self-locking mechanism to be contained in the pressure cooker upper handle in safeties.
Described eccentric wheel self-locking mechanism is that a push pedal is arranged in the upper handle chute, this push pedal can connect a top board by the axis hole mode, an eccentric wheel is fixed in upper handle by pivot pin simultaneously, and connect top board by a connection piece, one torque spring is installed between eccentric wheel and the pivot pin, and pressure cooker cover has a thrust valve rod moving up and down in the suitable part of upper handle.
Appropriate location has a sealing ring in described thrust valve rod, and is the O RunddichtringO, is the boundary with the sealing ring, and its upper end has a disappointing duct, and its lower end has outgassing groove, and the flexible back-up ring of its lower end appropriate location.
Description of drawings:
Fig. 1: this pressure cooker uses the structure principle chart of safeties;
Fig. 2: this pressure cooker uses the partial sectional view of overlooking of safeties;
Fig. 3: this pressure cooker uses the thrust valve rod fundamental diagram of safeties.
Use the embodiment of safeties to be further described below in conjunction with description of drawings to pressure cooker of the present utility model.
As Figure 1-3, pressure cooker of the present utility model uses safeties to adopt an eccentric wheel self-locking mechanism in upper handle, this eccentric wheel 9 is fixed in upper handle 11 by pivot pin 7, can about suitably rotate, be connected a top board 6 in the upper handle 11 by a connection piece 13 again, push pedal 10 connects a top board 6 by the axis hole mode, and a torque spring 8 is installed between eccentric wheel 9 and the pivot pin 7, and pot cover 1 in upper handle 11 appropriate locations have one can upper and lower lifting thrust valve rod 3 and corresponding valve opening 2.Be contained in an O RunddichtringO 4 in thrust valve rod 3 middle part locating slots 16, the duct 14 of losing heart, its top one is main aperture road, center, in around open the reasonable quantity aperture.Its underpart has outgassing groove 15, and the lower end appropriate location has a circlip 5.When pressure cooker closes when covering, pot cover 1 beginning is rotated along the pot tooth, be that eccentric wheel 9 convex surfaces are withstood by the pot serratd edge, eccentric wheel 9 contact positions are changeed backward, eccentric wheel 9 upper connectors, 13 drive top boards 6 and push pedal 10 move forward seals thrust valve rod 3, make thrust valve rod 3 be in opening, as Fig. 3 a, pressure cooker heating this moment, thrust valve rod 3 will lose heart, so can not go up pressure, reach to close and cover security requirement, when having only to 12 coincidences of upper handle 11 lower handles, eccentric wheel 9 enters a pot tooth recess, see Fig. 2, move after driving top board 6 and push pedal 10, thrust valve rod 3 is opened, this moment, pot cover 1 was pinned by eccentric wheel 9 with the pot body, and this moment, thrust valve rod 3 was by air pressure jack-up when in the pot proper pressure being arranged, and self sealss, as Fig. 3 b, when the pot internal gas pressure still when 5KPa is above, thrust valve rod 3 blocks top board 6, push pedal 10 just pushes away to get on, the eccentric wheel self-locking device just can not be opened, and reaches safety uncapping property requirement, when the pot internal gas pressure is reduced to 5KPa when following, this moment, thrust valve rod 3 dropped to opening automatically by the deadweight effect, but this moment pot still can not be opened, and must up push away push pedal 10, moves to seal the thrust valve rod and see that Fig. 3 a and eccentric wheel 9 produce recess on top board 6, just can open pot cover 1, reach the safety opening-closing cover requirement.
When pressure cooker operating valve and safety valve are malfunctioning, when pot inner pressure surpasses 180KPa, 0 RunddichtringO 4 is ejected locating slot 16 by air pressure, it is displaced downwardly to above the circlip 5, thrust this moment valve rod outgassing groove 15 is interlinked to the outside with pot cover 1 and sees Fig. 3 C, reaches quick exhaust step-down, has guaranteed safe handling, simultaneously after eliminating fault, as long as move into 0 RunddichtringO 4 in the locating slot 16 promptly reusable.
The utility model pressure cooker effect safeties have modern design, and compact conformation can be real Existing closing lid self-locking has again the overpressure protection buck functionality, can prevent effectively that pressure cooker is anti-fried, also manufactures This is low, good reliability, the advantage such as easy to use.
