Abstract
The utility model relates to a piston type automatic body locking device for pressure cooker, which is composed of a cooker body, a cooker lid, a locking stud, a sealing rubber bowl, an upper and lower piston rod and a piston seat. The piston seat is arranged on the cooker body. The piston rod is provided with the locking stud. The locking stud can pass through a locking hole on the cooker lid. The utility model has the advantages of simple structure, simple manufacturing process, strong practicability, low cost and easy cleaning. The utility model can reliably prevent misoperation. The utility model can ensure service property quality for a long time.
Description
The utility model belongs to the automatic lock uint of a kind of pressure cooker pot body piston type.
At present, the pressure cooker security seal is equipped with of all kinds, as patent 94212082.5 cover closing and opening safety device for pressure cooker, structure is complicated, technology is complicated, and easy cleaning is not damaged easily, practicality is strong inadequately, still surplus more atmospheric phenomenon in the pot in the time of can not preventing to uncap effectively.
The purpose of this utility model is to provide a kind of automatic lock uint of pressure cooker pot body piston type safe in utilization, simple in structure.
The utility model by pot body (8), pot cover (7), locking double-screw bolt (1), fluid sealant bowl (2), go up that lower piston rod (3), tapering are just adjusted cover (4), piston seat (6) is formed.Piston seat (6) is contained on pot body (8), lower piston rod (3) is housed in the piston seat (6), piston rod (3) and locking double-screw bolt (1) thread connection, fluid sealant bowl (2) is clipped between piston rod (3) and the locking double-screw bolt (1), and locking double-screw bolt (1) can pass the locking hole (9) on the pot cover (7).
The utility model is simple in structure, and technology is simple, and practicality is stronger, can be contained in arbitrary position of a pot body (8) upper edge, can prevent reliably that misoperation from being strong phenomenon of uncapping when still residual air is pressed in the pot, cost is very low, every as long as increase just can be gone into operation for 1.5 yuan on old-fashioned pressure cooker, the user is simple to operate, and is safe in utilization, understands at a glance, can take out cleaning, can guarantee service property (quality) for a long time, make producer and user all relieved, be worth promoting.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view.
As shown in Figure 1, piston rod (6) is just adjusted cover (4) seat on piston seat (6) by tapering, can control glue bowl (2) and cover optimum height between (7) by the height of adjusting cover (4), to reach best result of use.Simultaneously, because this is with tapering, can prevent that food from dropping on the piston seat, guarantee piston rod up and down freely, piston seat (6) is riveted tightly on one's body the pot by rivet (5).At the pot tooth upper punch recessed step of pot body (8) or pot cover (7), close the relative position when tight to determine pot cover and pot body, when guaranteeing in the pot air pressure to be arranged, locking double-screw bolt (1) can pass the locking hole (9) on the pot cover (1).The cap of locking hole (9), locking double-screw bolt (1), fluid sealant bowl (2), last lower piston rod (3), tapering is just adjusted cover, all can be circular, square, triangle, pentagon, hexagon or other geometry.
During work, not in place if pressure cooker closes lid, fluid sealant bowl envelope is locking hole incessantly, and steam is discharged from the hole, and no pressure in the pot reaches to close and covers purpose of safety; As get togather when covering, the pot internal gas pressure increases, and piston rod moves upward, owing to there is pressure glue bowl to turn over downwards, seal up locking hole, and the locking double-screw bolt ejects upwards, enters in the locking hole, with pot body and pot cover locking, before not arranged gas, the pot cover of not opening reaches the purpose of safety of uncapping, when having arranged gas, piston rod falls down automatically and can uncap safely.For the purpose of attractive in appearance, can add a cover on the locking hole, result of use is constant.In addition in use, when pressure did not boost piston rod, the locking double-screw bolt should cover security to guarantee to close a little more than the fluid sealant bowl.
