Description

The telescopic bottleneck of screw thread

Technical field

The utility model relates to the telescopic bottleneck of a kind of bottleneck structure of container, particularly screw thread.

Background technology

Liquid container is widely used, and often there is small amount of liquid to flow to the bottleneck outer wall in the process that is down liquid of unique deficiency and causes that bottleneck pollutes, the entire container of making dirty surface, this is the drawback of the common existence of liquid container institute in the market.

In order to solve above-mentioned drawback; The patent No. is that the utility model of ZL200820170140.3 provides a kind of telescopic oil outlet pipe not have the water clock bottleneck structure; It comprises and bottleneck bonded assembly bottleneck body and its bonded assembly bottle cap, it is characterized in that being provided with in the described bottleneck body by the flexible oil outlet pipe of bottle cap drive; It is that the top is provided with elastic draw hook and the upper flange that is located at the oil outlet pipe upper oral part to a pair of symmetry that extends below in the bottle cap that described bottle cap drives flexible oil outlet pipe structure; Said oil outlet pipe infraoral is provided with lower flange; Also be provided with spacing the button on the said oil outlet pipe.When falling oil, unload decap earlier; Bottle cap is pulled out oil outlet pipe because of the relation of elastic draw hook and upper flange unloading process of assembling; When oil outlet pipe be drawn out receive lower flange spacing after, the overhanging height of oil outlet pipe substantially exceeds the bottleneck height, even when falling liquid move too quickly this moment or hand is shaken; The liquid of pouring out can not drop on the bottleneck, and the small amount of liquid that remains in the oil outlet pipe upper oral part can be crossed the fuel return hole that is located on the bottleneck body and is back to container.

Said structure is well to have solved a small amount of flow liquid to flow to the bottleneck outer wall and cause that bottleneck pollutes; The phenomenon of making whole vessel surface dirty; But this lean on bottle cap unload process of assembling because of elastic draw hook cooperates with upper flange the direct mode that oil outlet pipe is pulled out; Can have damaged easily problem, service life is not long; And liquid return be through fuel return hole realize but the problem that liquid also can flow out from fuel return hole has also appearred simultaneously.

The utility model content

The purpose of the utility model is to provide a kind of liquid container bottleneck that can thoroughly solve to pollute for the deficiency that solves above-mentioned prior art, and can recycle the telescopic bottleneck of the screw thread of long service life.

To achieve these goals, the telescopic bottleneck of the utility model institute design-calculated screw thread comprises bottle cap, telescopic pipe and main body; Telescopic pipe places in the main body; The inwall of said bottle cap lower part is provided with the bottle cap negative thread, and said main body is a hollow structure, and the external wall of upper portion of main body is provided with bottle cap and connects outside thread; Bottle cap is connected outside thread through the bottle cap negative thread and is connected on the main body with bottle cap on the main body; The middle part inwall that it is characterized in that said main body is provided with threaded telescopic pipe flange connector, and the upper edge of threaded telescopic pipe flange connector is provided with position limiting convex ring, and the bottom outer wall of telescopic pipe is provided with the outside thread flange; The outside thread flange cooperates with the threaded telescopic pipe flange connector at main body middle part, and the top of telescopic pipe and bottle cap top are divided into the coupling linkage structure.

Said structure design can thoroughly solve the pollution problem of liquid container bottleneck, and thread connecting mode makes and the utlity model has and can recycle, the advantage of long service life.

The bottom integral type of said main body is connected with container, container perhaps is set on the wall within it connects negative thread, and when main body and container were integral structure, said position limiting convex ring snapped fit onto the threaded telescopic pipe flange connector upper edge in the middle part of the main body.This structural change makes that the field of application of the utility model is wider.

When main body and container when being threaded, the side ancient piece of jade, round, flat and with a hole in its centre of said lower body part is provided with the locking screw keyhole, is mainly used in when opening bottle cap, prevents to produce between main body and the container loosening.

In order to make raffinate flow back to container; The facial contour of the outside thread flange on the outer wall of said telescopic pipe bottom is that convex-shaped arc surface and spill cambered surface replace bonded assembly plum blossom shape structure, and the telescopic pipe die arrives the inside radius of the distance B at spill cambered surface center greater than position limiting convex ring..

The top of said telescopic pipe and bottle cap top can be the polygons that matees interlock each other, are divided into interior 12 corner structures as preferred bottle cap top, and the top of said telescopic pipe is the regular hexagon structure.This preferred structure makes that the utility model integral structure is attractive in appearance, and operability is better.

The telescopic bottleneck of the screw thread that the utility model obtains; When opening bottle cap in the use; Bottle cap rotation drive telescopic pipe moves up to the position limiting convex ring lower flat along the threaded telescopic pipe flange connector in the middle part of the main body and contacts with telescopic pipe outside thread flange upper plane; The blocking-up liquid in container flows out between main body and telescopic pipe, and it is suitable for reading to be higher than main body far away owing to telescopic pipe is suitable for reading, when liquid flows out from telescopic pipe, also can not make dirty main body outer wall and vessel surface; During capped; Telescopic pipe rotates; The threaded telescopic pipe flange connector at main body middle part separates with the outside thread flange of telescopic pipe bottom, and a small amount of raffinate on the telescopic pipe outer wall flows back in the container through the position limiting convex ring inwall at main body middle part and the space between the telescopic pipe outer wall, avoids waste; Guarantee that vessel surface is totally pollution-free; Simultaneously above-mentioned whole process has utilized the induced way that is threaded to replace in the prior art bottle cap to lean on elastic draw hook to cooperate the direct mode that oil outlet pipe is pulled out with upper flange unloading process of assembling fully, feasiblely the utlity model has and can recycle, the advantage of long service life.
