Abstract

The utility model relates to a push-free handle for pressure cookers. A latching valve is installed on a lid of the pressure cooker, and the inner of the latching valve is provided with a valve core which can move up and down under the action of pressure in the cooker. A sliding groove is arranged in an upper handle, and a supporting rod penetrates through a sliding hole of a sliding plate through a cam frame which is fixed in a cavity of the upper handle together with the sliding plate, wherein, the front end of which is provided with a central hole which is corresponding to the valve core of the latching valve on the cooker lid. The sliding plate makes reciprocating motion under the guiding of the supporting rod along the sliding groove in the upper handle under the action of the cam frame and a spring. The motion stroke of the sliding plate is determined by the motion of a cam on the upper end of the cam frame driven by a cam on the lower end of the cam frame propped up by a toothed ring of a cooker body. The utility model has the advantages of simple structure, durable parts, convenient operation and reliable safety performance.

Description

Pressure cooker is exempted from pushing handle

The utility model relates to a kind of pressure cooker and exempts from pushing handle.

The handle mechanism of existing pressure cooker is of all kinds, but exists problems.The complex structure that has, the inconvenience that operates makes troubles to the user; Though the structure that has is simple, part rapid wear in the mechanism brings unnecessary difficulty to the user.In order to satisfy consumer's requirement, make the folding lid security performance of pressure cooker better, operate easylier, designed the novel pushing handle mechanism that exempts from.

The purpose of this utility model be to provide a kind of simple in structure, part is durable, pressure cooker easy to use, that performance is safe and reliable is exempted from pushing handle.

The purpose of this utility model is achieved in that

It is that latching valve is contained on the pot cover, is provided with spool in the latching valve, and spool can move up and down under the pot inner pressure effect.Be provided with chute in the upper handle, slide plate is located in the chute of upper handle.The nose is provided with centre bore, and is corresponding with the latching valve spool on the pot cover.Slide opening is arranged on the slide plate, and support bar passes in the sliding chamber that slide plate is fixed on upper handle by cam holder.Slide plate is under the effect of cam holder and spring, and is by the support bar guiding, reciprocating in the upper handle chute.The movement travel of slide plate is to be moved along pot body serratd edge by the cam of cam holder lower end to push slide plate with the cam that drives the cam holder upper end and decide.

The utility model has the advantages that simple in structurely, part is durable, and is easy to use, safe and reliable.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the latching valve structure chart.

Fig. 3,4 is the cam holder structure chart.

Fig. 5 does not contact schematic diagram for the cam of cam holder lower end with the pot body.

Fig. 6 is that the cam of cam holder lower end contacts schematic diagram with the pot body.

Fig. 7 closes up schematic diagram fully for pot cover and pot body.

Fig. 8 is for having pressure, latching valve spool rising schematic diagram in the pot.

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

Shown in Fig. 1-8, latching valve 2 is installed on the pressure cooker cover 1, be provided with self-locking spool 9 in the latching valve 2, spool 9 can move up and down under the pot inner pressure effect.Be provided with chute in the upper handle 3, slide plate 4 structures such as Fig. 8 are arranged in the upper handle chute.Support bar 5 passes the slide opening 11 on the slide plate 4 and passes cam holder 6 simultaneously and is fixed in the upper handle, and it is corresponding with the latching valve spool 9 on the pot cover 1 that slide plate 4 front ends are provided with centre bore 10.Spring 7 is enclosed within slide plate 4 tail ends, and slide plate can move back and forth in the upper handle chute under the effect of cam holder 6 and spring 7.

The course of work of the present utility model is as follows:

When the cam 12 that is incorporated into cam holder 6 lower ends when pot cover 1 contact with a pot body serratd edge 14, the cam of cam holder 6 lower ends is under the top power of pot body serratd edge 14, and was mobile backward.It is mobile backward that the cam 13 of cam holder 6 upper ends pushes slide plate 4 compression springs 7 at this moment.As Fig. 5, slide plate 4 front end centre bores 10 depart from spool 9, and spool 9 is pressed not come, through hole and the extraneous normal open and do not boost of pot inner pressure by latching valve, and as shown in Figure 2, promptly pot cover closes and does not in placely boost.When pot cover is incorporated into, be that upper handle 3 is when overlapping fully with lower handle 8, the cam of cam holder lower end leaves a pot body serratd edge 14, slide plate 4 is under the effect of spring 7, recover reset condition, make slide plate 4 front end centre bores 10 concentric with latching valve spool 9, when in the pot pressure being arranged, the centre bore 10 that latching valve spool 9 passes slide plate 4 floats up.Pot is sealed pressurize, make the pressure cooker operate as normal, simultaneously slide plate 4 is pinned, can not move.Have in the pot this moment and press the lid of not opening, so entire mechanism has played the safeguard protection effect.

Claims

1, a kind of pressure cooker is exempted from pushing handle, latching valve is contained on the pot cover, be provided with spool in the latching valve, it is characterized in that being provided with in the upper handle chute, slide plate is located in the chute of upper handle, and the nose is provided with centre bore, corresponding with the latching valve spool on the pot cover, slide opening is arranged on the slide plate, and support bar passes in the sliding chamber that slide plate is fixed on upper handle by cam holder, and the cam holder two ends are cam.
