Description

Two sliding-tongue latching devices of heat preservation dinner flask and bung

Technical field

The present invention relates to heat preservation dinner flask, particularly relate to two sliding-tongue latching devices of a kind of heat preservation dinner flask and bung, belong to kitchen tools field.

Background technology

Heat preservation dinner flask is mainly comprised of staving and bung, and in order to make good-for-nothing good heat preservation performance, staving contacts and reaches sealing with bung, is conducive to again move, so be conventionally provided with the mechanism that is connected between staving and bung simultaneously.Existing conventional bindiny mechanism is generally staving and adopts screw socket to be connected with bung, but screw socket connection is only applicable to circular good-for-nothing, and troublesome poeration; Another kind is rotary switch, on the limit of staving, wing screw is installed, and opens a rectangular groove at bung edge, when ingot forwards 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 ingot helical for volume ratio is larger, exceed easy above bung and hand or the collision of other article.Therefore, the inventor has designed the various bindiny mechanisms between staving and bung, as Chinese patent 201120237784.1, name is called " handle linkage switch of heat preservation dinner flask ", and this technical scheme is at staving both sides mounting handle, and handle has linked switch, do not change the product structure of staving own, switch processing is than being easier to, easy for installation, the features such as cost province.But because handle is outside staving, volume ratio is larger, during transportation and packing, to remove, when using, user sets up, for some housewives, make troubles.

Summary of the invention

The object of the invention is in order to overcome the shortcoming of prior art, a kind of button that arranges in bung is provided, button drives dead bolt, and dead bolt coordinates with the lockhole of staving oral area, and simple in structure, volume is little, two sliding-tongue latching devices of easy to operate heat preservation dinner flask and bung.

The technical scheme of two sliding-tongue latching devices of heat preservation dinner flask of the present invention and bung is, comprise staving and bung, bung is divided into bottom set plate, on bung, there is handle, between bung and staving, jockey is set, two that jockey described in it is characterized in that is included in staving oral area is respectively shaped with two lockholes, one at bung is shaped with two solid dead bolts, in the other end of bung, movable snap close is set, described movable snap close comprises button, by pipe, lifting spring, guide cylinder, slide plate, promote spring and spring jacking block, in bung, be shaped with button hole, button is set in button hole, in button, arrange by pipe, by lifting spring is set in pipe, by control, there is plate, under button, there is guide cylinder, in guide cylinder, be shaped with guide plate, in guide plate, be shaped with inserting plate hole, the both sides of guide cylinder are shaped with fixedly ear, by screw, by fixing ear, guide cylinder is fixed on below bung, plate is through inserting plate hole, under guide cylinder, slide plate is set, in slide plate, be shaped with angled-lift splits, one of slide plate is shaped with two dead bolts, the other end of slide plate is shaped with spring and buckles, described angled-lift splits contacts with the plate by pipe, two described dead bolts match with the lockhole of staving, described spring links and connects promotion spring, there is spring jacking block the other end that promotes spring, spring jacking block is arranged on the bottom of bung.

The invention discloses two sliding-tongue latching devices of a kind of heat preservation dinner flask and bung, at two of staving oral area, be respectively shaped with two identical lockholes, one at bung has two fixedly dead bolts, the other end of bung arranges movable snap close, the structure of movable snap close comprises button from top to bottom, by pipe, lifting spring, guide cylinder, slide plate, promote spring and spring jacking block, in bung, be shaped with button hole, button up passes button hole below button hole, because button is cylindrical shape and has limit eaves in bottom, so button can not pulled out from button hole, in columnar button, arrange one circular by pipe, by control, there is top board, the bottom of pressing pipe reach button below, by lifting spring is set in pipe, a upper crown of lifting spring is below pipe top board, by the bottom of pipe, there is opening to be divided into two plates, circular guide cylinder is set below button, middle part at circular guide cylinder is shaped with guide plate, next crown of lifting spring is on guide plate, in guide plate, have inserting plate hole, by the plate under pipe, pass inserting plate hole, circular guide cylinder outer wall is shaped with fixedly ear, by screw, guide cylinder is fixed on below bung, under guide cylinder, slide plate is set, in slide plate, be shaped with angled-lift splits, angled-lift splits contacts with the head of plate, head by plate slides along angled-lift splits, slide plate is produced mobile, it is the topmost action of movable snap close, the dead bolt reaching on one, slide plate exits from lockhole, in the other end of slide plate, there is spring to buckle, buckle at spring on a crown that promotes spring, the other end that promotes spring withstands on spring jacking block, spring jacking block is arranged on the bottom of bung.During work, first the fixedly dead bolt of one of bung is inserted in the lockhole of staving, how passable arbitrary lockhole be, knob down again press...withes one's finger, button drives by pipe, make lifting spring compressed, by the plate of pipe bottom, through the inserting plate hole of guide cylinder, stretch out downwards with the angled-lift splits of slide plate and collide, the head of plate slides along angled-lift splits, slide plate is produced mobile, promotion spring is compressed, thereby make dead bolt on slide plate to inside contracting, bung is put into bowl opening downwards, unclamps finger, slide plate outwards moves under the effect that promotes spring, and dead bolt inserts in lockhole.Latching device is arranged in bung, does not need to expand good-for-nothing volume, adopts push-botton operation, uses very convenient, light.

Two sliding-tongue latching devices of heat preservation dinner flask of the present invention and bung, described is shaped with banking stop by pipe outer wall, is shaped with stopper slot in guide plate, and banking stop matches with stopper slot.There is coordinating of banking stop and stopper slot, avoided rotating by pipe, guaranteed that plate contacts with angled-lift splits.Described slide plate bottom is shaped with chute, is shaped with sliver on base plate, and chute matches with sliver.There is coordinating of chute and sliver, dead bolt accurately inserted in lockhole.
