Description

Pressure cooker is exempted from pushing handle safety opening-closing device

The utility model relates to a kind of pressure cooker and exempts from pushing handle safety opening-closing device, belongs to pressure cooker safe practice field.

Existing pressure cooker handle apparatus form is a lot, and the characteristics of handle arrangement are also varied, but through long-term practice, and we find that push button handle inconvenient operation in pressure cooker open and close brings many troubles to the user; Though the handle that has is relatively simple for structure, but mechanism and the relative motion of lower handle slideway are long in the upper handle, and frictional resistance is excessive during motion, user's opening and closing pressure cooker of must exerting oneself, even cause deformation or breakage, make troubles and waste to the business and consumer.

The purpose of this utility model is the problem at above-mentioned existence, and provides a kind of simple in structure, does not establish push button, and the folding lid is laborsaving, and the pressure cooker of high safety is exempted from pushing handle safety opening-closing device.This device can be realized: (1) pot cover closes and does not in placely boost.(2) the pressure pot cover of not opening is arranged in the pot.(3) high-intensityly only start and end depression bar, thereby guarantee pressure cooker safety operate as normal.

The purpose of this utility model is achieved in that

Be provided with in the upper handle chute and only start and end depression bar, both bottoms are connected by spring, only start to have the hole, end the depression bar afterbody and stretch in the hole of only starting, and lower handle is provided with chute, and the chute head end connects slideway, and it is shaped as

, the chute tail end connects slideway, and it is shaped as Can establish push button like this, the bottom of only starting can skid off from the lower handle slideway.

The utility model has the advantages that simple in structurely, easy to use, lower handle chute slideway has changed in the past

Shape, the chute afterbody with The slideway of shape connects, and the junction forms the right angle, and this structure need be provided with push button, could skid off from the right angle that chute is connected with slideway by the promotion of the push button bottom of only starting.The utility model handle is for exempting from pushing handle, and the folding pot cover is easy, has played pressure cooker safeguard protection effect, meets the pertinent regulations of national standard " pressure cooker security requirement " fully, and its application will provide more satisfied product for the consumer.

Fig. 1 is the utility model structural representation.

Start till Fig. 2 and end the depression bar structural representation.

Fig. 3 is lower handle chute and slideway plane.

Describe the utility model in detail below in conjunction with accompanying drawing:

As Figure 1-3, latching valve 2 is installed on the pressure cooker cover 1, and the latching valve spool can move up and down under the pot inner pressure effect.Only start 4 with end depression bar 5 and be connected in the chute that is arranged on upper handle 3 by spring 6, only start 4 to have the hole, end depression bar 5 afterbodys and stretch in 4 holes of only starting, only depression bar 5 tail ends are fork-shaped, and are provided with overhead kick.Lower handle 7 is provided with chute 11, and chute 11 head ends connect Shape slideway 8, the chute tail end connects

The slideway 10,9 of shape, only start 4 with end depression bar 5 front-rear reciprocation movement under the effect of lower handle slideway 8,9,10 and spring 6, thereby reach the motion of control latching valve spool.

Can realize in sum closing not in place when pot cover, promptly end depression bar 5 to contact and only start 4 when not contacting lower handle slideway 9 with lower handle slideway 8, end depression bar 5 and cover the latching valve spool, make on the spool not come, make and pass through the latching valve structure hole normal open external world in the pressure cooker, no pressure plays the safeguard protection effect in the pot; When continuing to contact with lower handle slideway 8, depression bar 5 only starts 4 when beginning to contact when ending with lower handle slideway 9, end depression bar 5 and under the effect of lower handle slideway 8, break away from the latching valve spool gradually, meanwhile only start 4 under the effect of lower handle slideway 9, to push down the latching valve spool gradually, the latching valve spool still is in by pressure condition, and pot inner pressure can't raise; When only starting 4 when finishing under the effect of lower handle slideway 10, to move in the motion of lower handle slideway 9, end depression bar 5 and lose control fully the latching valve spool, thereby but the latching valve spool 4 push down and reached pot cover and close and not in placely do not boost by only starting.

Only start 4 under the effect of lower handle slideway 10, to break away from the latching valve spool gradually, when pot cover is incorporated into, be that upper handle 3 is when overlapping fully with lower handle 7, only start 4 to break away from the latching valve spools, the latching valve spool rises under the pot inner pressure effect latching valve structure hole is sealed, and makes the pot inner pressure rising, after the latching valve spool raises, stoped and only started 4 and end travelling forward of depression bar 5, lower handle slideway 10 has also stoped 4 side-to-side movements of only starting simultaneously, and the pressure pot cover of not opening is arranged in the pot this moment.The whole pushing handle safety opening-closing device of exempting from has played pressure cooker safeguard protection effect.

Claims (2)

1, a kind of pressure cooker is exempted from pushing handle safety opening-closing device, it is characterized in that: in the upper handle chute, be provided with and only start and end depression bar, both bottoms are connected by spring, the hole of only starting to have, ending the depression bar afterbody stretches in the hole of only starting, lower handle is provided with chute, and the chute head end connects slideway, and it is shaped as

The chute tail end connects slideway, and it is shaped as
