Abstract
The utility model belongs to the improvement aiming at an auxiliary safety device of an existing pressure cooker. The utility model comprises a control pin which is installed on a cooker lid and is provided with a rubber sealing member, a safety plate which is positioned on a hand lever and is provided with a guide rod, a spring which is abutted on the guide rod and a guiding groove which is opened on a lower hand lever, wherein, the guide rod can slide along the guiding groove and can drive the safety plate to slide above the control pin. When the cooker lid is safely closed, the front end of the safety plate is not extended and cover below the control pin which is propped up and sealed by air pressure, when the cooker lid is not closed, the safety plate is pressed on the control pin to enable the cooker to lie in exhaust condition. When the inner of the cooker has pressure, the control pin can not descend and the cooker lid can not be opened. The utility model has the advantages of convenient operation, safe operation, simple production process, etc., and the utility model can used by being assembled on various types of pressure cookers.
Description
The utility model belongs to the pressure cooker auxiliary security and uses control device.
For fear of because of the improper contingency that causes of pressure cooker lid folding, Patent Office of the People's Republic of China once on July 1st, 1996 applied for that the patent No. is 96237132, name is called the patent of " pressure cooker handle ", it is provided with a self-locking mechanism on the usual pressure pot handle, when pot cover covers when not in place, pot inner pressure can not raise; When having pressure not drain in the pot, pressure cooker is in self-locking state, and pot cover can not be opened, thereby has guaranteed the pressure cooker open and close process safe.But the structural slab more complicated in these safeties, inconvenient operation is damaged in the use easily.
It is a kind of simple in structure, easy to operate that the purpose of the utility model is to provide, the pressure cooker safety opening-closing handle of long service life.
The technical solution of the utility model is such: it utilizes the self structure of existing pressure cooker, the control pin that can move up and down, have rubber seal is housed on pot cover, in upper handle, be equipped with and have guide rod, front end and place on the control pin and can and withstand on the spring of guard plate guide rod one side, and on lower handle, have control and lead a groove along the guard plate of pot cover radial slippage.Lower end of the guide rod can be led a groove along lower handle and be slided.Lead a groove and be camber line shape or oblique line shape track, it is not held and is provided with positioning table; Guide rod is in leading a groove slipping, and guard plate is left and right sides rectilinear translation above the control pin then.When pot cover closes up, upper and lower handle is complete when overlapping, and guide rod rests on the positioning table, and guard plate is not stretched just and covered on the control pin.
When pot cover and a pot body when not closing up, guard plate is pressed on the control pin, and the control pin can not rise, and and valve seat between gapped and be in exhaust condition, cause pot inner pressure not rise; In normal operation, a steam jack-up in the control pin quilt pot, and unhinderedly pass on the self-locking hole of upper handle, its underpart is enclosed on the valve seat; When steam in the pot does not discharge when finishing, the control pin does not fall, and guard plate can not move, and pot cover is in self-locking state and can't opens, thereby opens the contingency that pot cover causes under the situation of having avoided the pot internal gas pressure not eliminate effectively.
Obviously, the utlity model has easy to use, handling safety, advantage such as production technology is simple, cost is low, and the life-span is long can be assemblied on the pressure cooker of various models and use.
Below in conjunction with embodiment shown in the drawings the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model when closing up fully.
Fig. 2 is the A-A view of Fig. 1.
As shown in Figure 1, pressure cooker safety opening-closing handle comprise the control pin that is contained on the pot cover 14 and place the guard plate 7 that has guide rod 9 in the upper handle 8 and roof pressure on guard plate 7 guide rods 9 spring 10 and open and on lower handle 11, lead a groove 12.Control pin 4 make " worker " and font, its axle center has gas port, the lower end has the side opening that communicates with gas port, and is contained in seal washer, nut 2 and is fixed in the valve seat 6 on the pot cover 1, leaves the gap 3 of 1-2mm therebetween.In order to guarantee that control pin 4 is fitted on the valve seat 6 after the air pressure jack-up good sealing property is arranged, above control pin 4 lower end boss, be with rubber seal 5; Upper handle 8 and control pin 4 have self-locking hole on the relative position.Guard plate 7 front ends are stretched and are covered above control pin 4, and the rear end is provided with the guide rod 9 of making one with it, and the centre of guide rod 9 is provided with groove, and an end of spring 10 places in the groove, and the other end withstands on the upper handle 8.Guide rod 9 lower ends can be led a groove 12 along lower handle 11 and be slided, and lead a groove 12 and are oblique line shape, and it is not held and is provided with positioning table, referring to Fig. 2.Open in the process of closing at pot cover 1, guard plate 7 is led at guide rod 9 under the effect of a groove 12 and spring 10, move left and right above control pin 4; When pot cover 1 closes up fully, upper and lower handle 11 over against, guard plate 7 front ends fail to cover just on control pin 4, control pin 4 is risen by air pressure jack-up.
When pot cover 1 did not close up fully with a pot body 13, guard plate 7 was pressed on the control pin 4 all the time, control pin 4 can not on move, make pot interior gas by outside gap 3 and the gas port discharge pot, air pressure can not rise.
In the time of will opening pot cover 1 by force when certain air pressure is arranged in the pot, as long as pot inner pressure is controlled pin 4 and is through all the time in the self-locking hole 11 greater than control pin 4 deadweight gravity; do not fall; make guard plate 5 can not parallelly be moved, cause pot cover 1 to open, thereby play the safeguard protection effect by card.
