Description

Insulation good-for-nothing lid driving switching mechanism

Technical field

The utility model relates to the insulation good-for-nothing, particularly relates to a kind of insulation good-for-nothing lid driving switching mechanism, belongs to the kitchen tools field.

Background technology

The insulation good-for-nothing mainly is made up of staving and bung, and in order to make the good-for-nothing good heat preservation performance, staving contacts with bung and reaches sealing, helps again moving simultaneously, so between staving and bung, be provided with the mechanism that is connected usually.Existing bindiny mechanism commonly used is generally staving and adopts screw socket to be connected with bung, but the screw socket connection is only applicable to circular good-for-nothing, and troublesome poeration; Another kind is a rotary switch, on the limit of staving, wing screw is installed, and opens a rectangular groove at the bung edge; When ingot forwarded to rectangular groove parallel position, bung can take out, when ingot forwards to the orthogonal position of rectangular groove; Bung is fastened, and can not raise.Use the shortcoming of wing screw bigger, exceed easy and hand or the collision of other article above the bung as volume ratio.Therefore, people have designed the various bindiny mechanisms between staving and the bung, like Chinese patent 200920122080.2; Name is called the lid clamping body of good-for-nothing " insulation ", and this technical scheme relies on stirring up and down of handle to reach bung and tightens with staving and be connected, and reliability is than higher; Operate also more convenient, but because need be through being installed in outer lever operated of good-for-nothing, not only complex structure; The installation trouble, and volume is big, heavy, especially packs, freight is expensive.Chinese patent 200820121342.9 for another example, and name is called " bindiny mechanism of insulation good-for-nothing staving and bung ", and brace and strap that this technical scheme relates to staving and staving inner bag cooperate with the projection of bung; Strap has comprised upper and lower and side stand; And the card muscle, complex geometry, difficulty of processing is big; Particularly relate to parts such as staving inner bag, the assembling trouble.

Summary of the invention

The purpose of the utility model is in order to overcome the shortcoming that prior art exists; Provide a kind of and on the cornice of staving, thrust unit is installed, rely on thrust unit that bung is connected, relate to simple in structure; Volume is little, and operation is incubated good-for-nothing lid driving switching mechanism especially easily.

The technical scheme of the utility model insulation good-for-nothing lid driving switching mechanism is: comprise staving and bung, it is characterized in that being shaped on the lifting spring seat on the edge, described staving two, in the lifting spring seat lifting spring is installed; Be shaped on guide pad in the both sides of lifting spring seat separately and promote spring housing, promote the promotion spring is installed in the spring housing, shift knob is installed on lifting spring; Shift knob top is shaped on convex platform and lower platform, and the bottom outer wall of shift knob is shaped on the ring muscle, in lifting spring seat, guide pad and promotion spring housing, switch cover is arranged; Be shaped on button hole in the switch cover; The size of button hole and shift knob top are consistent, the ring muscle of shift knob bottom and the pig of button hole, and the bottom of switch cover is shaped on gathering sill, promotes spring eye and stifled groove; Promoting spring eye matches with one that promotes spring; Gathering sill matches with guide pad, and stifled bar is installed in the stifled groove, is shaped on the switch inserted sheet at two of bung; Under stifled bar, be shaped on the switch jack, the switch inserted sheet matches with the switch jack.

The utility model discloses a kind of insulation good-for-nothing lid driving switching mechanism, utilize edge, staving two that the driving switching mechanism is set, not be used in the outer installation auxiliary device of staving, volume is little; Switching mechanism is pegged graft with bung two and cooperated, and is simple in structure, easy for installation; Production cost is low, and described driving switching mechanism one is to make the shift knob can oscilaltion, once by opening; The 2nd, make switch jack meeting move left and right, assurance switch inserted sheet is pushed down and is thrown off, and uses very convenient.Whole use is: when needs are shut bung, bung is placed on the bowl opening, with the outside of hand propelled switch cover; Make to promote spring by compression, shift knob up pushes away at the following shift knob of the effect of lifting spring when shifting onto, and the convex platform of shift knob and lower platform are raised in the button hole; The end face of shift knob lower platform is just in time blocked by button hole, and the ring muscle is blocked by the bottom surface of the button hole of switch cover, and shift knob can not drop out; Staving and bung are closed, and be very docile, high insulating effect.In the time will opening bung, the convex platform of the shift knob that press...withes one's finger down makes lifting spring by compression; Make the lower platform of shift knob drop to switch cover below, switch cover and stifled bar etc. under the effect that promotes spring, switch cover and stifled bar to extrapolation; Make the convex platform of shift knob still be higher than button hole; Oral area by button hole blocks, and the switch inserted sheet of bung is come out from the switch jack of stifled bar, and bung can be picked up.In actual product, all be equipped with inner bag and heat-insulation layer in staving and the bung.

The utility model insulation good-for-nothing lid driving switching mechanism, described gathering sill is a T shape gathering sill, and corresponding guide pad is a T shape guide pad, and T shape gathering sill matches with T shape guide pad.T shape gathering sill cooperates T shape guide pad to operate steadily, reliably.Described lifting spring seat comprises semi-moon shaped seat ring; Be shaped on two protruding chewing in the seat ring; Each is protruding, and of chewing separately with lifting spring contacts; Described shift knob comprises semi-moon shaped hollow switch body, is shaped on two fixed legs in the hollow switch body, and fixed leg contacts with the other end of lifting spring.Lifting spring one crown protruding chewing, and the other end heads on fixed leg, and lifting spring is not shifted, and shift knob is processed ducted body, like lid, covers in the outside of lifting spring seat, under the effect of lifting spring, can only move up and down, and left-right and front-back does not move.Periphery at button hole below the said switch cover is shaped on retaining muscle and slide plate, and the retaining muscle contacts with the ring muscle of shift knob, and slide plate contacts with the lower platform upper surface of shift knob.Retaining muscle and slide plate make the wall attenuation of switch cover more, see like recess from below, and the retaining muscle is pushed down and encircled muscle shift knob is not dropped out, when opening, the lower platform of shift knob slide into slide plate below.Described stifled bar be shaped on T shape lead blind groove with promote the spring blind hole.There is lead blind groove of T shape to supply the movable and location of guide pad, promotes the spring blind hole and supply to promote the arrangement of spring head and stop.
