Description
One, technical field
The utility model relates to daily used a kind of pressure cooker, especially relates to a kind of clamp-type open and close cover structure of pressure cooker.
Two, background technology
In order to realize the tight fastening of pot body and pot cover, reach the purpose that improves pot inner pressure safely, people have designed various types of pressure cookers.Press the difference of closed form, pressure cooker can be divided into revolving type, gland-type, fall to covering formula, clamp-type etc.
Chinese patent has been announced a kind of novel pressure cooker open and close cover structure No. 200620044097.7, comprise a pot body, pot body and at least two clamps that the edge of pot cover and pot body can be snapped together, the hinged connecting rod that equates with clamp quantity on pot cover, the leading section of connecting rod and the straight bar part of clamp are hinged, central authorities at pot cover are provided with a rotating disk, rotating disk can be stirred the pin joint swing of connecting rod around its pot cover, moves radially thereby promote corresponding clamp, realizes the folding of pot cover.But the open and close cover structure of this pressure cooker, clamp broke away from the planar annular of pot cover fully when pot cover was opened, when deformation appears in connecting rod or clamp, clamp just is difficult to smooth the cooperation with pot cover, cause complicated operation, complex structure, the demanding shortcoming of the accuracy of manufacture, in order to reduce the accuracy of manufacture, to reduce bayonet socket and adopt the clamp of little radian.The clamp of little radian can not encase the edge of pot cover fully, and under the situation of pot inner high voltage, small deformation may take place the pot cover that is not wrapped between the clamp, causes gas leakage, reduces whole withstand voltage properties.
Three, summary of the invention
Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, provide a kind of easy to operate, resistance to pressure good, simple in structure, clamp-type open and close cover structure that the accuracy of manufacture requires low pressure cooker.
The clamp-type open and close cover structure of pressure cooker comprises the pot cover that is provided with ring edge, is provided with the pot body of ring edge, clamp that at least 2 cross sections take the shape of the letter U, that described pot cover and pot body oral area can be fastened, is connected on the clamp to drive the connecting rod of clamp; Described pot cover be provided with the pressure regulator valve of regulating pot inner pressure, can lifting under the pot inner pressure effect latching valve, cover plate, described cover plate is provided with the hole of matching with pressure regulator valve, latching valve, pot button; Described pot cover center is provided with a pot button, and described pot button is provided with the manual piece that is used to drive described connecting rod, and connecting rod below, pot button middle part is provided with the interlock plate that is used to connect each connecting rod; It is characterized in that: described clamp one end is hinged on the pot cover, and the other end is hinged on the head of connecting rod; It is hinged with described clamp, pot cover, interlock plate, manual piece successively that described connecting rod arrives afterbody from the head, and described connecting rod is fulcrum, is the point of application, is that application point constitutes a leverage with the pin joint of itself and clamp with the pin joint of itself and manual piece with the pin joint of itself and interlock plate.
Further, on the axle of described pot button below return spring is housed, described return spring compresses described connecting rod.
Further, described clamp is a semicircular arc, and two clamps are radially and are hinged on the pot cover diagonally.
Further, described connecting rod can be to be hinged on the clamp by movable sliding pin, and described movable sliding pin is provided with return spring.
Further, described connecting rod by mobile jib be positioned at " protruding " shape groove that is connected with connecting rod and form, what the self-locking hole that allows the latching valve free lifting is arranged on described " protruding " shape groove and stop that latching valve rises only rises hole slot, when described clamp was in buckling state, described latching valve was positioned at described self-locking hole; When described clamp was in open mode, described latching valve was positioned at the described hole slot that only rises, and stoped latching valve to rise.
Further, described self-locking hole can be two circular holes that are interconnected with only rising the hole, and the diameter of self-locking hole is greater than the diameter that only rises hole slot.
For this reason, technical conceive of the present utility model is: the pressure cooker original state is closed, press manual piece, described manual piece drives connecting rod around around itself and the center position rotation towards the pot body of the pin joint of the pin joint of interlock plate, itself and return spring, under the effect of interlock plate, each connecting rod rotates synchronously, is fulcrum with the fixing point, swings towards the direction away from the pot body thereby drive clamp, and pot cover is opened; Unclamp manual piece, connecting rod under the effect of return spring around its with the hinged support of pot cover towards the rotation of pot body direction, under the effect of interlock plate, each connecting rod rotates synchronously, thereby the drive clamp is fulcrum with the stiff end, swings towards pot body direction, and pot cover closes.When clamp was in closure state, latching valve matched with the self-locking hole of connecting rod " protruding " shape groove, and when in the pot pressure being arranged, latching valve rises, stop connecting rod to rotate, thereby realize self-locking, when pot inner pressure descends, latching valve descends, and connecting rod can freely rotate, self-locking releasing; When clamp does not close safely, only rising hole slot and match on latching valve and the connecting rod plush copper, connecting rod " protruding " shape groove stops latching valve to rise, and guarantees that pot inner pressure does not rise, and improves security.
Clamp one end of the present utility model is hinged on the pot cover, even pot cover edge, clamp produce miniature deformation, clamp also can cooperate smoothly with pot cover, has easy to operate, simple in structure, the accuracy of manufacture and requires low advantage; Clamp of the present utility model can encase the pot cover edge fully, and good airproof performance is safe.
Below in conjunction with specification drawings and specific embodiments the utility model is further described.
