Abstract
The utility model relates to an automatic safety device for opening and closing a lid of a pressure cooker, which is composed of a cooker body, a cooker lid, a locking pin, a sealing rubber sleeve, a locking hole, a supporting seat having taper and rivets. The supporting seat having taper is arranged above the cooker body. The locking pin is arranged in the supporting seat, which is provided with the sealing rubber sleeve. When the pressure cooker closes the lid, the locking pin aims at the position of the locking hole. The utility model has simple structure, safe opening and closing the lid, favorable effect, long service life and cheap cost.
Description
The utility model belongs to a kind of pressure cooker open and close cover automatic safety.
At present, the pressure cooker security seal is equipped with of all kinds, as patent 95244228.0 pressure cooker open and close safety controls, patent 95230981.5 pressure cooker safety devices, structure are complicated, and technology is complicated, easy cleaning not, damage easily, practicality is strong inadequately, can not effectively solve when uncapping still surplus more atmospheric phenomenon in the pot.
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 is by pot body, pot cover, locking pin, seal rubber sleeve, locking hole, band tapering bearing, rivet are formed, pot body (7) top edges is dashed installing hole, band tapering bearing (3) is housed, be placed with locking pin (2) in the bearing (3), the relevant position of pot cover (6) dashes locking hole (5), and seal rubber sleeve (1) interference is locked in the groove location of locking pin (2), and pot body tooth and pot cover tooth part (6) have gone up boss with mutual location.When pressure cooker gets togather when covering, locking pin aligns the locking hole position.
The utility model structure is very simple, uses as safe as a housely, effective, and the life-span is long, can prevent reliably that misoperation from promptly closing lid phenomenon of uncapping not in place and strong during band air pressure in the pot, makes producer and user all relieved, is worth promoting.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view.
As Fig. 1, shown in Figure 2, this device is earlier at the good installing hole of pot body (7) upper punch, use rivet (4) (countersunk head then, snap rivet all can), with bearing (3) the method, edge position on one's body the pot of riveting tightly, height can be when design size, the height of adjusting installing hole and bearing tapering solves, again seal rubber sleeve (1) is locked in the groove location of lock pin (2) by the interference method, the back is put into bearing (3) to the locking pin of band seal rubber sleeve, at the relative position of pot cover towards one of locking hole, and partly play a boss at pot body tooth and pot cover tooth and solve orientation problem, promptly accuse and install.After installing, locking pin (2) should be a little more than seal rubber sleeve (1), when pressure cooker does not get togather when covering, air pressure rises locking pin (2), withstands on the edge or pot cover sealing station of locking hole, and seal rubber sleeve does not have effect, the pot internal gas pressure is discharged from locking hole, plays the effect of closing lid safety.When pressure cooker gets togather when covering, locking pin aligns the locking hole position, produces air pressure in the pot with locking pin jack-up from bearing, seal rubber sleeve is translated into the plane downwards, seals up locking hole, does not allow deflation, the locking pin jack-up that makes progress, enter locking hole, pin pot cover, when in the pot air pressure being arranged, can not uncap again, treat after pot interior exhaust that locking pin utilization deadweight falls after rise automatically, reaches the security of uncapping.This installation cost is quite cheap, and every cover is no more than 1 yuan, can satisfy requirements of large-scale production to greatest extent and because of price is low, and quality is good and be convenient to sell.Seal rubber sleeve can be a bowl type, plain cushion type, locking pin (2) can be done squarely circle, hexangle type and other shape, the tapering part of band tapering bearing, can be divided into two parts, locking hole can be done squarely for for the purpose of both artistic and practical, and other geometry, also can add a cover, but total effect is constant, principle is constant.
