Abstract
The utility model relates to a self-locking handle mechanism for pressure cookers, which is formed by connecting a handle provided with a self-locking device with a cooker lid with a sealing member, wherein, the handle is fixed on the top surface of the cooker lid, and the Self-locking device is provided with a press-button, a spring and a lever with a movable pin which are fixed on the cooker lid through a connection piece and a supporting frame. When in use, only the movable pin falls into the margin of cooker teeth on the cooker body and is locked after the cooker lid and the cooker body are closed properly, the pressure cooker can gain pressure and the cooker lid can not be opened. The cooker lid can only be opened by relieving self-lock after discharging the pressure by first pressing the press-button, etc., so explosion accidents due to misoperation can be prevented from occurring. The utility model has the advantages of compact structure, small size, convenient use, high safety and reliability.
Description
The utility model relates to a kind of safety control of pressure cooker, particularly a kind of pressure cooker self-locking handle mechanism that is used for the folding of controlled pressure pot on the pressure cooker lid that is installed in.
For pressure cooker can more safely be worked, improve its security insurance coefficient, prevent the pressure cooker explosion accident that causes because of misoperation, generally all on pressure cooker, increase the self-locking device of dress safety valve and various different structures, have their own characteristics each.
The purpose of this utility model is to provide a kind of pressure cooker self-locking handle mechanism, its compact conformation, safety coefficient height, has auto-lock function, dependable performance, easy to use.
The utility model is achieved in that pressure cooker self-locking handle mechanism is connected institute by the handle that self-locking device is installed and forms with the pot cover that has seal, and described handle is fixed on the end face of pot cover, and the lever that described self-locking device is button, spring, have a removable pin is fixed on the pot cover by connector and support.
Fig. 1. structural representation of the present utility model.
Fig. 2. removable pin is position view on pot cover.
Fig. 3. removable pin is position view on the pot body.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Lever (5) is the prolate bar shaped of middle band through hole; Support (7) on the shape of through hole is arranged; Connector is pin (8).
Guide pad (9) on flat of open slot arranged; Removable pin (10) one ends are cylindrical, and an end is have rectangular opening plate shaped.
Respectively there is a joint pin on pot cover (2) upper surface both sides, and there is a groove centre, and there is a through hole at the edge.
Handle (1) shape and pot cover (2) are complementary, and through hole are arranged, passage and button hole on it.
Seal (3) is connected with sliding sleeve by the piston boit of band sealing ring, is fixed on pot cover (2) and goes up same as the prior art.
Earlier removable pin (10) is put into the through hole on pot cover (2) edge, again with guide pad (9), support (7) spot welding respectively is fixed on the pot cover (2), guide pad (9) is welded on the top position of pot cover (2) edge through hole, and cooperate also spacing with removable pin (10), the rectangular opening that lever (5) one ends pass on the removable pin (10) is connected with removable pin (10), other passes lever (5) with pin (8) by end and support (7) is movably connected on the support (7), between groove on the pot cover (2) and lever (5), put into spring (6), the handle (1) that will have button (4) at last is screwed on two joint pins of pot cover (2), and self-locking handle mechanism is assembled into.
During use, pot cover (2) is covered on pot body (11), closing when covering removable pin (10) on pot cover (2) is between A-B shown in Figure 3 on the position, promptly do not put in place, at this moment removable pin (10) is by jack-up, under pin (8) effect, lever (5) head is depressed, and makes the piston boit in the seal (3) can not jack-up.When removable pin (10) moved to the B position, removable pin (10) was fallen into edge's pinning that a pot body (11) is gone up the pot tooth, and at this moment the motion stops jack-up in the seal (3) seals, and presses on the pressure cooker, and pot cover (2) can not be opened.If will uncap, also need click button (4) earlier, make lever (5) head push down seal (3) downwards it can not be sealed, allow a pot inner vapor from passage, discharge, remove self-locking after the pressure release, at this moment just can open pot cover (2).Therefore just can prevent to take place the explosion accident of pressure cooker because of misoperation, safe in utilization, reliable.
The utility model is compared with prior art: so the handle of mechanism is mounted in the top of pot cover, and from Locking device is mounted in again in the cavity that forms between handle and pot cover, its compact conformation, little, the user of volume Just, improved again safety coefficient.
