Referring to Fig.1 2, in the new embodiment of the utility model, jam plate 70 is jam plate mating surface 72 far from 40 end face of pressing plate, the The inner bottom surface of one inner cavity 11 is pivot mating surface 13, CONTACT WITH FRICTION between jam plate mating surface 72 and pivot mating surface 13, when first When pivot 10 rotates, jam plate 70 is able to drive by the frictional force of jam plate mating surface 72 and pivot mating surface 13 and is rotated.At other In embodiment, other modes can also be used and be fixed.

The working principle of the utility model is as follows:

When closing lid, jam plate is rotated with lid, and the big end of side chamber body of the roller in jam plate is to small end motion, roller and lock Plate, transmission shaft are in interference fit, so that roller has very big damping force to transmission shaft；Simultaneously as transmission shaft and connecting shaft Cooperated by spacer pin, thus the damping force that transmission shaft is subject to will be passed to connecting shaft, and connecting shaft is connect with pedestal and common It remain stationary motionless.Lid can be made to remain stationary without damping force under the action of external force motionless, realize lid in Product Definition The limit function at any angle uncapped in angle, when practical operation, if thinking closing lid, slightly firmly, structure is simple, uses Family is easy to operate.

When uncapping, damping force is substantially zeroed, specifically: during uncapping, lid drives jam plate rotation, and roller is along lock The arching trajectory of the damping space of plate moves, and jam plate drives roller, to big end motion, to roll at this time along the small end of the side chamber body of jam plate Column keeps clearance fit with the mating surface of transmission shaft, transmission shaft does not stress, and keeps relatively quiet always situated in the track big end of jam plate Only, pedestal does not have the active force of direction of rotation to lid during lid is opened, thus lid can be opened easily.

The utility model can be applied to the heavier a plurality of cooking apparatus of lid, especially complain and quarrel loudly etc..For fryer, There are motor, wind wheel, heating component etc. in fryer pot cover part, causes pot cover more many than general pot cover weight, when pot cover is opened, operation , can be very inconvenient when picking and placing article on one side if personnel hold pot cover on one side, and it is dangerous, for this purpose, if pot cover may be implemented arbitrarily It will be conveniently many when angle self-locking function.It is existing be usually realized by knob, button, this for new user in use, Under the premise of not reading specification, it is difficult to grasp the application method of knob, button, can make troubles to user's operation.Compared to it Under, the structure of the utility model is not needed using any knob, button, it is only necessary to which manpower normally uncapped, closing lid It easily opens, pot cover can be fixed in any angle, have great convenience for the user.

In conclusion the utility model overcomes the shortcomings that prior art, a kind of next self-locking knot of damping force close to the inner portion is provided Structure, uncap may be implemented uprightly to limit to maximum angle rear cover body, and any angle pot cover can be fixed voluntarily during closing lid, real Existing any angle of the pot cover in the maximum opening and closing lid angle of Product Definition is fixed, and different clients difference fixed angle is met Demand, and be not required to additional switch, additional power fix pot cover, operate simpler, conveniently.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein, Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model, These modes are fallen within the protection scope of the utility model.
