Abstract
The utility model relates to a handle of a pressure cooker, which is composed of an upper handle, a connection rod, a press plate of the connection rod, a spring, a sealing control pin of a rubber ring, a lower handle and a control concave position of the lower handle, wherein the connection rod can radially slide in a guide groove along a cooker cover, and a connection rod control pin can slide along a guide surface of the concave position of the lower handle. A push rod of a safety indication valve can pass through a hole of the connection rod when interior pressure of the pressure cooker is more than 5KPa, and the cooker cover can not be opened; the push rod of the safety indication valve drops down to the original position when the interior pressure of the pressure cooker is under 5KPa, and the lower handle can be pulled to open the cooker cover. The utility model has the advantages of simple structure, simple processes and safety.
Description
The utility model belongs to a kind of pressure cooker handle.
At present, do not have safety device on traditional pressure cooker handle, normal the automatic chain safety device of patent 94212082.5 pressure cooker air pressure occurs in the pot air pressure being arranged still and strong maloperation phenomenon such as uncap, patent 93202581.1 cover closing and opening safety device for pressure cooker, structure are complicated.Technology is complicated, and easy to clean is not fragile, and cost is higher.
The pressure cooker handle that provides a kind of security performance strong, simple in structure is provided the purpose of this utility model.
The utility model is made up of upper handle, connecting rod, connecting rod pressing plate, spring, lower handle, lower handle control recess, upper handle has guide groove in (3), connecting rod (6) is housed, by pressing plate (12) orientation, pressing plate (12) is contained on the upper handle (3), and connecting rod (6) can radially slide along pot cover in guide groove, and connecting rod (6) front end has the hole corresponding to safety indicator valve (5), it is connecting rod control pin (7) that there is a pin rear end, can slide along the spigot surface of lower handle recess in pin (7) lower end.Pin (7) resets by spring (9), connecting rod (6) is slided and reset, when raising, pot inner pressure make safe indicator valve (5) push rod pass the hole of connecting rod (6), connecting rod (6) is fixing, and connecting rod control pin (7) is stopped by the lower handle recess, and pot cover pins and do not open, when descending, pot inner pressure makes safe indicator valve (4) the push rod original position that descends back, connecting rod (6) can radially slide along pot cover, and when staff rotated upper handle, connecting rod control pin (7) withdrawed from spring (9) effect lower edge lower handle control recess.O-ring seal control pin (10) is arranged on the upper handle (3), connect O-ring seal (11), control pin (10) other end is by the shoulder hole of described spring (9) connecting pin (7), the spigot surface that rubber sealing control pin (10) is arranged on the lower handle control recess, when upper handle did not overlap with lower handle, control pin (10) heads on cushion rubber (11) can not seal pot cover (2) and pot body (1).
The utility model is to design according to GB13623 " aluminum pressure cooker safety and performance requirement) ", when pot inner pressure when 5KPa is above, the push rod of safe indicator valve passes the hole of connecting rod (6), pot cover is not opened, improved the pressure cooker usage safety performance, simple in structure, easy to operate, good airproof performance, easy cleaning, not fragile.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is a utility model lower handle concave surface schematic diagram;
As shown in Figure 1, the pot body (1) and the concavo-convex tooth contraposition of pot cover (2) are buckled well, " closing " word direction by upper handle moves upper handle (3), the recess (8) of control pin (7) and lower handle (4) that is installed in the connecting rod (6) of upper handle rigidly connects when touching, because of spring (9) withstands O-ring seal control pin (10), O-ring seal (11) top is recessed, make O-ring seal gas leakage, the this moment as the heating of heating, liter does not play pressure in the pot; During correct the use, upper handle (3) overlaps with lower handle (4), connecting rod control pin (7) and O-ring seal control pin (10) are fixing in lower handle control recess (8), O-ring seal is round and seals with pot body (1) and pot cover (2), be forced into pressure more than 5KPa when heating in the pot, the push rod of safe indicator valve (5) rises the hole of passing connecting rod (6), and the auto lock pot cover is not opened, when stopping the heating kettle internal pressure when 5KPa is following, the push rod of safe indicator valve returns original position again.Move by " opening " word direction of upper handle (3) and can open pot cover, thereby improve pressure cooker security performance in use.
