Description
Technical field
This utility model relates to dip-tube device, relates in particular to a kind of dip-tube anticreep assembly.
Background technology
Dip-tube is always difficult point of the prior art with the fixation assembly of cooperage spigot.At present, producer arranges the groove of an annular in the bottom of cooperage spigot.Using extrusion friction between dip-tube and cooperage spigot groove internal-and external diameter to realize dip-tube and cooperage spigot between the two fixing, this structure is the most unstable.Dip-tube is easily made to deviate from from toroidal cavity along with the liquid sloshing in container in transportation.Additionally, due to thickness is the thinnest at the restriction cooperage spigot stress of material and mould, the most cracking phenomenon.How overcoming the problems referred to above is the direction that those skilled in the art need research.
Summary of the invention
For solving the problems referred to above, this utility model provides a kind of dip-tube anticreep assembly.
Its concrete scheme used is as follows:
A kind of dip-tube anticreep assembly, including dip-tube, cooperage spigot and hold-doun nut, described dip-tube end is provided with flared tube, and the internal diameter of described flared tube is more than the internal diameter of dip-tube pipe shaft；Be provided with the first boss bottom described cooperage spigot, described first boss is provided with the second boss；The first through hole, the second through hole and third through-hole it is provided with in described hold-doun nut；Described first through hole two ends are respectively communicated with upper surface and second through hole of hold-doun nut；Described third through-hole two ends are respectively communicated with the lower surface of the second through hole and hold-doun nut；Internal diameter and the second boss external diameter of described flared tube adapt；The internal diameter of described third through-hole and the external diameter of the first boss adapt, and the internal diameter of described first through hole is less than the external diameter of flared tube.
By using this technical scheme: hold-doun nut is set on the pipe shaft of dip-tube, being connected on by the Flaring Pipe Sleeves on the second boss makes dip-tube connect as one with cooperage spigot, pipe shaft along dip-tube drags hold-doun nut until hold-doun nut is socketed on the first boss, utilize the stuck dip-tube of hold-doun nut, thus effectively prevent coming off of dip-tube.
Preferably, in above-mentioned dip-tube anticreep assembly: described first boss outer is provided with external screw thread, and described third through-hole is provided with the female thread corresponding with described external screw thread.
By using this technical scheme: utilize intermeshing of external screw thread and female thread, further the annexation between strengthening hold-doun nut and cooperage spigot.
Compared with prior art, this utility model simple in construction, be easily achieved.Can effectively prevent dip-tube in transportation from coming off from cooperage spigot.Prevent stress cracking, increase ultimate torque, improve air-tightness.
Accompanying drawing explanation

Fig. 2 is the enlarged diagram of a-quadrant in Fig. 1.
In above-mentioned accompanying drawing, each parts are as follows with the corresponding relation of reference:
1, dip-tube；2, cooperage spigot；3, hold-doun nut；11, flared tube；21, the first boss；22, the second boss；211, external screw thread；31, the first through hole；32, the second through hole；33, third through-hole；331, female thread.
Detailed description of the invention
Embodiment 1 the most of the present utility model:
A kind of dip-tube anticreep assembly, including dip-tube 1, cooperage spigot 2 and hold-doun nut 3.Described dip-tube 1 end is provided with flared tube 11, and the internal diameter of described flared tube 11 is more than the internal diameter of dip-tube 1 pipe shaft；Be provided with the first boss 21 bottom described cooperage spigot 2, described first boss 21 is provided with the second boss 22；Circle the first through hole the 31, second through hole 32 and third through-hole 33 it is provided with in described hold-doun nut 3；Described first through hole 31 two ends are respectively communicated with upper surface and second through hole 32 of hold-doun nut 3；Described third through-hole 33 two ends are respectively communicated with the second through hole 32 and the lower surface of hold-doun nut 3；Internal diameter and second boss 22 external diameter of described flared tube 11 adapt；The internal diameter of described third through-hole 33 and the external diameter of the first boss 21 adapt.The internal diameter of described first through hole 31 is less than the external diameter of flared tube 11.Described first boss 21 outer is provided with external screw thread 211, and described third through-hole 33 is provided with the female thread 331 corresponding with described external screw thread 211.
In practice, its assembling process is as follows:
Hold-doun nut 3 is set on the pipe shaft of dip-tube 1, being socketed in by flared tube 11 on second boss 22 makes dip-tube 1 connect as one with cooperage spigot 2, pipe shaft along dip-tube 1 moves hold-doun nut 3 until third through-hole 33 is socketed on the first boss 21, utilize intermeshing of external screw thread 211 and female thread 331 so that hold-doun nut 3 is fixed as one with cooperage spigot 2.Utilize the first through hole internal diameter 31 characteristic less than flared tube 11 external diameter of hold-doun nut 3, it is achieved stuck to dip-tube 1, thus effectively prevent coming off of dip-tube 1.
The above; it is only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
