Abstract
The utility model discloses a cork for a thermos bottle attached to the bottle, which is composed of a cover body, an elastic cork sleeve and a fixer for the cork sleeve. A hollow pipe provided with steps is downwards formed in the center of the upper end surface of the cover body, the elastic cork sleeve is in the shape of a sleeve pipe, and an inner cavity of the utility model is in a drum shape. The fixer for the cork sleeve is composed of a screw bolt on the surface of the cover and a fixing nut of a cork sleeve, a screw cap of the fixing nut of a cork sleeve is provided with a clamping ring for the cork sleeve, and the upper end of the elastic cork sleeve is sheathed on the steps on the center of the cover body. The lower end of the elastic cork sleeve is sheathed on the clamping ring of the fixing nut of a cork sleeve, and the screw bolt on the surface of the cover and the fixing nut of a cork sleeve are used for tightly fixing the lower end of the elastic cork sleeve. The utility model has the advantages that the cork and the cover are integrated, the diameter of the cork sleeve can be adjusted, and the appearance of the thermos bottle of the utility model is shapely. A mouth of the thermos bottle is sanitary, the sealing performance is good and reliable, and the utility model is an ideal cork attached to the bottle.
Description
The utility model relates to the adjustable conjuncted gag of a kind of vacuum flask, belongs to the vacuum flask accessory.
Chinese patent CN90213124.4 discloses a kind of " connection open type health Thermos bottle top ", it is formed by filling in loam cake, enclosing cover, the rubber automatic control, plug is thread connection with enclosing cover in loam cake and the rubber and plastic automatic control, and the bottle cap of this structure is to adjust it by the upper-lower position of plug in enclosing cover in the adjustment automatic control rubber and plastic to cooperate the suitable degree of degree of tightness with internal diameter of the bottleneck.In use, often make plug displacement in it because the user is screwed, thermos flask airtight performance variation, and difficult the discovery influence heat insulation effect, moreover plug position in will often adjusting needs hand to grab interior plug and turns during adjustment, so very unhygienic, also cumbersome.
The purpose of this utility model is at above-mentioned shortcoming of the prior art, and provides a kind of adjustable reducing plug sleeve conjuncted gag.
The purpose of this utility model is achieved in that it is made up of lid, elasticity plug sleeve and plug sleeve fixture, and center, lid upper surface forms the hollow pipe with step downwards.The elasticity plug sleeve is a cannula-like, the plug sleeve fixture is made up of capping bolt and plug sleeve hold-down nut, on the nut of plug sleeve hold-down nut, be provided with the plug sleeve snap ring, the resilient plug set upper side is enclosed within on the step at lid center, the lower end of elasticity plug sleeve is enclosed within on the snap ring of plug sleeve hold-down nut, and fastening by capping bolt and plug sleeve hold-down nut.
The utility model can also adopt following measure to realize, is provided with featherway on the inwall of lid hollow pipe, is provided with feather key on plug sleeve hold-down nut outer wall.Be provided with keyway on the inwall of two ends up and down at the resilient plug cover.Be provided with protruding key on the lid hollow pipe step and on the correspondence position on the snap ring of plug sleeve hold-down nut.
Elasticity plug sleeve inner chamber becomes cydariform, and the two ends wall thickness has lateral ribs greater than middle wall thickness on its outer surface up and down.The elasticity plug sleeve is made by nontoxic rubber or nontoxic vinyl chloride.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A profile.
By illustrated embodiment as can be known, it is made up of lid 3, elasticity plug sleeve 2 and plug sleeve fixture, and center, lid 3 upper surface forms the hollow pipe with step downwards, is provided with the featherway 5 of two symmetries on the inwall of hollow pipe.On the step of hollow pipe, be provided with resilient plug and put the corresponding protruding key 6 of keyway.
Elasticity plug sleeve 2 is a cannula-like, and its inner chamber becomes cydariform, and the two ends wall thickness has lateral ribs greater than middle wall thickness on its outer surface up and down, and its effect is compensation and increases it and interior elasticity and the seal through cooperating of bottleneck.Be provided with keyway 7 on the inwall of two ends up and down at the resilient plug cover.Elasticity plug sleeve 2 is made by nontoxic rubber or nontoxic vinyl chloride.
The plug sleeve fixture is made up of capping bolt 1 and plug sleeve hold-down nut 4.The nut of capping bolt 1 cooperates with lid 3 center small stairs.Plug sleeve hold-down nut 4 is provided with plug sleeve snap ring 8 for having the tubular nut of nut on its nut.On the outer wall of snap ring 8, be provided with and put the corresponding protruding key 6 of keyway with resilient plug.On the outer wall of plug sleeve hold-down nut 4, be provided with feather key 9.
Elasticity plug sleeve 2 combines as a whole by plug sleeve fixture and lid 3, and the resilient plug set upper side is enclosed within on the step at lid center, and the lower end of elasticity plug sleeve is enclosed within on the snap ring 8 of plug sleeve hold-down nut, and fastening by capping bolt 1 and plug sleeve hold-down nut 4.Feather key 5 in the feather key 9 of plug sleeve hold-down nut 4 and the lid hollow pipe matches, and its effect is to guarantee that plug sleeve hold-down nut 4 can only move up and down, and can not rotate.The keyway 7 that resilient plug puts respectively with lid center step on protruding key 6 and the protruding key 6 on the plug sleeve hold-down nut snap ring match, its effect is that elasticity plug sleeve 2 can only be shortened or extend, and can not rotate by warp-wise, to guarantee in the daily use repeatedly, the elasticity that cooperates of plug sleeve and bottleneck can not produce and neglect pine and neglect tight phenomenon.
The adjustable reducing of elasticity plug sleeve is by tightening or loosening capping bolt 1 and realize, twist capping bolt 1 tightly more, press elasticity plug sleeve 2 flat more, by the reason in " drum chamber " by plug sleeve hold-down nut 4, elasticity plug sleeve 2 stage casings are to expanding all around, and promptly diameter becomes big.Otherwise, capping bolt 1 to be unscrewed, the diameter of elasticity plug sleeve 2 just diminishes.When this conjuncted gag matches with vacuum flask for the first time, cooperate the suitable degree of degree of tightness as long as the plug of elasticity plug sleeve 2 directly adjusted to internal diameter of the bottleneck, just can normally use then.
The utility model has the advantages that gag combines as a whole and to overlap diameter adjustable, use this novel vacuum flask, the outward appearance integrated beauty, the bottleneck health is good, and is airtight good and reliable, is a kind of comparatively ideal conjuncted gag.
