Abstract
The utility model provides an anti-loose pressure-cooker handle, consisting of a cooker cover and an upper handle mutually fixed. The thrusting valve base is provided with a thrusting rod with a sealing ring and an air hole, a thrusting plate to prevent the opening of pressure handle in the cooker by mistake, a thrusting rod fixedly integrated with the thrusting plate, a spring for the reset of the thrusting plate and a supporting plate, etc. The utility model improves the non-fixing thrusting valve base into a fixing structure with the cooker cover, which not only keeps the original safety function of preventing the opening of the handle by mistake due to the pressure in the cooker, but also adds the fixing points of the hander and the cooker cover from two to three, thereby reinforcing the connection without causing the loose of the handle for a long time and reducing unnecessary troubles during using.
Description
Technical field
The utility model relates to the anti-loosening structure of rotary extrusion type spinning pressure cooker handle.
Background technology
Rotary extrusion type spinning pressure cooker handle is fixed on the pot cover limit with two pieces of sunk screws usually, owing to open by the parallel swing in the handle left and right sides during pot cover folding, on the force transmission to two of its swing piece sunk screw, use certainly will cause screw loosening for a long time, therefore the user wants frequent trip bolt, makes troubles to use.Pressure cooker cover is provided with the thrust valve for safe opening simultaneously, the function of the thrust valve seat of this thrust valve only is fixedly thrust valve rod, having under the pressure condition and thrust valve rod synchronization lifting, the mating reaction of the thrust plate in it and the upper handle, spring etc. is to guarantee to prevent under the elevated pressures situation in the pot that pot cover from opening, when pot inner pressure just can be uncapped during less than 5KPa.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and provide the anti-loosening minimizing of a kind of handle to use the pressure cooker handle of trouble.
The technical scheme that the utility model solves is: anti-loosening pressure cooker handle, comprise by sunk screw and make 2 fixing pot covers and upper handle, be provided with between the two the thrust valve seat and in have the thrust valve rod of sealing ring and passage, be provided with in the upper handle and prevent to have in the pot thrust plate of pressing the handle mistake to open, this thrust plate and throw-out lever are fixed with one, the both ends of the spring that thrust plate is resetted links to each other with thrust plate with support plate respectively, it is characterized in that described thrust valve seat simultaneously as the 3rd fixing point of pot cover and upper handle and by nut also tightly on pot cover.
The faying face of described thrust valve seat and pot cover is provided with sealing ring.
Compared with prior art, the not fixed structure that the utility model has only improved the thrust valve seat for the fixed structure of pot cover, the thrust valve is original to be avoided having in the pot outside the safety effect of holding up out handle having kept, make the fixing of handle and pot cover increase to three fixing points simultaneously by two fixing points, reinforced annexation greatly, make handle for a long time with not loosening, reduce the unnecessary trouble in using.
Description of drawings
Fig. 1 has provided structural representation of the present utility model.
The specific embodiment
Embodiment to the utility model is described in detail again according to above-mentioned accompanying drawing.
As shown in Figure 1, pot cover of anti-loosening pressure cooker handle (1) and upper handle (2) are done at 2 by two pieces of sunk screws (10) and are fixed, and pot cover is connected on pot body (9) by pot cover sealing ring (11), forms sealing in the pot.The thrust valve is arranged between upper handle and the pot cover, form by thrust valve seat (3) and thrust valve rod (4), the thrust valve seat is the multidiameter tubular construction, top is positioned in the upper handle pre-manufactured hole, the bottom is shaped on screw thread, by nut (13) and tightly on pot cover, make the thrust valve seat fix no lifting action, simultaneously with the faying face of pot cover on sealing ring (14) is set, the fastening thrust valve seat of nut is that upper handle increases an anti-loosening fixing point with being connected of pot cover, the thrust valve seat has groove in the side at corresponding thrust plate position, is convenient to thrust plate (5) and pushes and block the thrust valve rod and prevent that it from opening.The thrust valve rod is located in the thrust valve seat and promotes lifting by steam, passage is arranged on it and be provided with sealing ring (12).
Be located at thrust plate (5) head that prevents the thrust valve rod in the upper handle and open and be the jag shape, perpendicular to the thrust valve rod, rear end and throw-out lever (8) are fixed with one, spring (7) one ends that thrust plate resets are linked to each other with support plate (6) on being fixed on upper handle, the other end links to each other with the thrust plate rear portion, and the active force of spring makes thrust plate block the thrust valve rod all the time forward.
When not having pressure in the pot or being lower than 5KPa, the thrust valve rod is descending the position, the state that promptly descends, and pot cover can be opened at any time.When pot inner pressure during greater than 5KPa, the thrust valve rod rises to topmost, blocks thrust plate and moves forward, and this moment, throw-out lever was stuck in the lower handle (not shown) groove, and pot cover just can not be opened.
Claims (2)
1. anti-loosening pressure cooker handle, comprise by sunk screw (10) and make 2 fixing pot covers (1) and upper handle (2), be provided with between the two thrust valve seat (3) and in have the thrust valve rod (4) of sealing ring (12) and passage, be provided with in the upper handle and prevent to have in the pot thrust plate (5) of pressing the handle mistake to open, this thrust plate and throw-out lever (8) are fixed with one, spring (7) two ends that thrust plate is resetted link to each other with thrust plate (5) with support plate (6) respectively, it is characterized in that described thrust valve seat (3) simultaneously as the 3rd fixing point of pot cover and upper handle and by nut (13) also tightly on pot cover (1).
2. anti-loosening pressure cooker handle according to claim 1, described thrust valve seat (3) is provided with sealing ring (14) with the faying face of pot cover (1).
