The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.

A kind of damping structure of uncapping, extremely shown in Figure 6 such as Fig. 1, comprising that pot cover 1, pot body 2, pot cover 1 and be connected by rotating shaft 3 between the body 2 with stewing, rotating shaft 3 two ends are connected in the draw-in groove of pot body 2, be arranged with torsion spring 4 in the rotating shaft 3, two external parts of torsion spring 4 are connected in respectively pot body 2 and pot covers 1, and pot covers and also is provided with cap-opening mechanism on 1, pot covers and is provided with damping block 5 on 1, offers corresponding friction plate 6 on pot body 2.

Because pot cover 1 when just opening, be by inactive state to motion state, pot covers 1 rotary speed from slow to fast, to cover in order realizing stewing 1 at the uniform velocity, to open stably, need to frictional resistance also be ascending.

Therefore, damping block 5 is set to the inclined-plane with the end face that friction plate 6 contacts.

Perhaps damping block 5 is set to cambered surface with the end face that friction plate 6 contacts.

Friction plate 6 is set to cambered surface with damping block 5 contact-making surfaces.The end face of above-mentioned damping block 5 is set to inclined-plane or cambered surface, and the contact-making surface of friction plate 6 is set to cambered surface, and damping block 5 is better contacted with friction plate 6, effectively produces frictional force, and can make its smooth frictional rotation, can not be stuck.Along with the angle of uncapping increases, damping block 5 covers 1 with pot and turns to certain angle, and damping block 5 increases with friction plate 6 contacts area of pot body 2, and the frictional force of generation also increases, and the speed that slows down and uncap; When arriving certain angle, damping block 5 can reduce again with friction plate 6 contacts area, and the frictional force of generation also and then reduces, like this so that stew and cover 1 and slowly steadily uncap.

To shown in Figure 6, pot covers 1 and is provided with damping block cover 7, offers sleeve joint hole 8 on the damping block cover 7 such as Fig. 3, and damping block 5 is provided with socket post 9, and socket post 9 is provided with projection 10, and socket post 9 passes sleeve joint hole 8, and projection 10 is connected in sleeve joint hole 8.The connected mode of clamping is simple in structure, and is durable, makes easily and assembles.

As shown in Figure 1, damping block 5 and friction plate 6 complete two covers that are set to provide enough frictional force, and are symmetrical arranged, and it is 1 stressed even that pot cover.

Damping block 5 and friction plate 6 are damping block 5 and the friction plate 6 of silica gel or rubber, and silica gel and rubber have preferably coefficient of friction, are suitable as the material that the frictional force device is provided.

It should be noted that at last: above only is preferred embodiment of the present utility model; be not limited to the utility model; although with reference to embodiment the utility model is had been described in detail; for a person skilled in the art; it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing; perhaps part technical characterictic wherein is equal to replacement; but all within spirit of the present utility model and principle; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
