Summary of the invention:
The purpose of this utility model provides a kind of pressure cooker self-locking device simple in structure, esy to use, safe and reliable.
The utility model is achieved in that
A kind of pressure cooker self-locking device, include upper handle, lower handle, latching valve, slide block, latching valve is arranged on the pressure cooker cover, the latching valve spool can be gone up under the effect of pot inner pressure, following motion, described lower handle is provided with slider slideway, slider slideway is made up of positive and negative slope two parts, described slide block is the L type, front end at the horizontal part of slide block is provided with valve opening, the vertical portion of slide block is provided with the spring location and installation hole of matching with spring anchor point on the upper handle, a side of slide block vertical portion is provided with the slide block backing pin, the horizontal part of slide block is arranged in the slide block slot of upper handle, and be connected with upper handle elasticity by spring, slide block can be stuck on the upper handle by the slide block backing pin, and slider slideway one side of lower handle is provided with and the corresponding contact of slide block backing pin.
Above-mentioned valve opening is and the corresponding strip of latching valve spool hole.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is simple in structure, and is easy to use;
2, the utility model also is in when being not suitable for uncapping in the pressure cooker internal pressure, and when promptly also having pressure in the pot, latching valve is in locking state, avoid pot cover to open, pot inner pressure the excessive user of causing injure, and eliminated the potential safety hazard that in use exists, and is safe and reliable;
3, the utility model in use, when normal occlusion covers, have " rub-a-dub " ring, if do not have the sound indication drowning to get togather, need to check, avoid unnecessary damages;
4, the utility model is applicable to the pressure cooker equal pressure container.

Fig. 2 is the upward view of upper handle of the present utility model;
Fig. 3 is the perspective view of slide block of the present utility model;
Fig. 4 is the front view of lower handle of the present utility model;
Fig. 5 is slide block of the present utility model and lower handle slideway contacting structure schematic diagram;
Fig. 6 is the structural representation when going up lower handle and closing up fully of the present utility model.
The specific embodiment:
With specific embodiment the utility model is further described below, referring to Fig. 1-6:
A kind of pressure cooker self-locking device, include upper handle 3, lower handle 4, latching valve 2, slide block 5, latching valve 2 is arranged on the pressure cooker cover 1, latching valve spool 21 can be gone up under the effect of pot inner pressure, following motion, described lower handle 4 is provided with slider slideway 41, slider slideway 41 is made up of positive and negative slope two parts, described slide block 5 is the L type, front end at the horizontal part 51 of slide block 5 is provided with valve opening 511, the vertical portion of slide block 5 is provided with the spring location and installation hole 52 of matching with spring anchor point 32 on the upper handle, a side of slide block 5 vertical portions is provided with slide block backing pin 7, think that with slide block backing pin 7 side of corresponding slide block slot 31 is provided with slide block backing pin stuck point 33, the horizontal part 32 of slide block 5 is arranged in the slide block slot 31 of upper handle 3, and be connected with upper handle 3 elasticity by spring 6, slide block 5 can be stuck on the slide block backing pin stuck point 33 on the upper handle 3 by slide block backing pin 7; Slider slideway 41 1 sides of described lower handle 4 are provided with and slide block backing pin 7 corresponding contacts 42.
Above-mentioned valve opening 511 is the strip hole, and corresponding with latching valve spool 21.
The course of work of the present utility model is as follows:
In the use, in pot, there is not pressure, latching valve spool 21 is in the state of whereabouts, the stroke of the locking campaign of latching valve 2 is by slideway 41 decisions of lower handle 4, contact with slideway 41 on the lower handle by the head of slide block 5, track according to slideway 41, can promote slide block 5 moves toward interior, slide block backing pin 7 is stuck on the upper handle on 3 the slide block backing pin stuck point 33, when pot cover 1 is incorporated into, promptly go up, lower handle 3,4 when overlapping fully, can send clear and melodious " rub-a-dub " ring, indicating that pressure cooker lid 1 has got togather, if do not have sound indication pot cover 1 not get togather, need to check, till pressure cooker lid 1 gets togather, at this moment, valve opening 511 (if pot cover 1 is incorporated into half, valve opening 511 is in closure state) on same axis on latching valve spool 21 and the slide block 5, pot inner pressure reaches certain scope after heating, the valve opening 511 that latching valve spool 21 can pass slide block 5 rises, just can reach the sealing pressurize in the pot like this, make the pressure cooker operate as normal, this moment is under the effect of latching valve 2 and slide block 5, can not normally uncap, promptly have when pressure can not open pot cover in the pot; When boiling, when also having air pressure in the pot, latching valve spool 21 can not float under the effect of pot inner pressure down, pot inner pressure is sealed, simultaneously, the upper end of latching valve spool 21 is stuck in the valve opening 511 of slide block slide block 5 is pinned, that is: latching valve 2 is in locking state, then can't open pot cover 1, entire mechanism plays the safeguard protection effect; When pot inner pressure was reduced to normal pressure, latching valve spool 21 was in falling state, and the valve opening 511 of slide block 5 can not blocked in the upper end of latching valve spool 21, and at this moment, turn upper handle 3 under the effect of lower handle slideway 41 and spring 6, can be opened pot cover 1.
