Abstract

The utility model discloses a kind of flexible pipe anti-racking means, comprise flexible pipe or pen container, head and lid, it is characterized in that, flexible pipe or pen container front end internal fixation have a sleeve pipe, the sleeve pipe rear end connects a baffle plate, sleeve pipe has inlet point near on the sidewall of baffle plate, and the sleeve pipe other end place of sleeve pipe one end and close inlet point extends internally respectively and forms two cast projectioies; Head one end inserts inside pipe casing, its external diameter is identical with the internal diameter of 2 sleeve pipe projectioies of sleeve pipe, and there is a head projection in this head one end outside, is stuck between 2 sleeve pipe projectioies of sleeve pipe inboard, form one section space between head projection and the sleeve pipe projection, spring is housed in the middle of the space; Flexible pipe or pen container are provided with securing device in the outside of securement head, and lid is installed on flexible pipe or the pen container by securing device; The utility model can prevent effectively that flexible pipe class device is squeezed and the situation of fluid because of carelessness.

Description

The flexible pipe anti-racking means

Technical field

The utility model relates to a kind of flexible pipe, is meant a kind of anti-racking means of flexible pipe concretely.

Background field

When liquid was contained in flexible pipe or the similar squeezable device, as long as pinch flexible pipe a little, liquid will be extruded from the head, and was very convenient.If but run into because of carelessness, also often extrude easily, cause waste, especially adorn the flexible pipe of some cosmetics liquids, when carrying, run into easily, in case extrude, will make dirty clothing or suitcase, cleaning is got up pretty troublesome.

The utility model content

The utility model aims to provide a kind of anti-racking means of flexible pipe, prevents to be expressed to flexible pipe because of carelessness with regard to fluid.

The utility model is realized its purpose by following technological means: flexible pipe or pen container front end internal fixation have a sleeve pipe, the sleeve pipe rear end connects a baffle plate, sleeve pipe has inlet point near on the sidewall of baffle plate, and the sleeve pipe other end place of sleeve pipe one end and close inlet point extends internally respectively and forms two cast projectioies; Head one end inserts inside pipe casing, its external diameter is identical with the internal diameter of 2 sleeve pipe projectioies of sleeve pipe, and there is a head projection in this head one end outside, is stuck between 2 sleeve pipe projectioies of sleeve pipe inboard, form one section space between head projection and the sleeve pipe projection, spring is housed in the middle of the space; Flexible pipe or pen container are provided with securing device in the outside of securement head, and lid is installed on flexible pipe or the pen container by securing device.

The utility model is all right: head can be the porous fluid, single hole fluid or hairbrush; Securing device is a buckle-type, perhaps is outside thread, and there is the negative thread that matches with it the lid inboard.

Compared with prior art, the utlity model has and to prevent to be expressed to because of carelessness the situation of flexible pipe,, remove lid and push then fluid smoothly a little in case cover lid just can prevent to push fluid with regard to fluid.

Description of drawings

Fig. 1 is the structural representation of the utility model flexible pipe leak-proof device.

Wherein, 1, flexible pipe or pen container, 2, baffle plate, 3, spring, 4, inlet point, 5, head, 6, lid, 7, the sleeve pipe projection, 8, the sleeve pipe projection, 9, the head projection, 10, sleeve pipe.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:

Embodiment 1, flexible pipe or pen container 1 front end internal fixation have a sleeve pipe 10, sleeve pipe 10 rear ends connect a baffle plate 2, sleeve pipe 10 is in having inlet point 4 near on the sidewall of baffle plate 2, and the sleeve pipe other end place of sleeve pipe 10 1 ends and close inlet point extends internally respectively and forms two cast sleeve pipe projectioies 7,8; Head 5 one ends insert sleeve pipe 10 inside, its external diameter is identical with the internal diameter of sleeve pipe projection 7,8, there is a head projection 9 in the outside of head 5 above-mentioned ends, be stuck between 2 sleeve pipe projectioies 7,8 of sleeve pipe inboard, form one section space between head projection 9 and the sleeve pipe projection 7, spring 3 is housed in the middle of the space; Flexible pipe or pen container 1 are provided with screw thread with the outside of securement head 5, and there is the screw thread that matches with it lid 6 inboards.

When not screwing on lid 6, spring 3 is in elongation state, and head 5 is released, so the inlet of head 5 leaves baffle plate 2, flexible pipe or pen container 1 internal liquid enter head 5 by inlet point 4, reach the fluid purpose.Under the effect of external force, when screwing on lid 6 gradually, head 5 is inwardly advanced, up to making the inlet of head 5 be close to baffle plate 2, form the sealing state of head 5, even flexible pipe or pen container 1 interior liquid were squeezed and can not enter head 5 by inlet point 4 this moment, spring 3 is in compressive state, when outwarding winding lid 6 once more, spring 3 is replied elongation state, head 5 is released, stopped till head projection 9 moves up to sleeve pipe projection 8, this moment, the inlet of inlet point 4 and head 5 was unimpeded.

Embodiment 2, except flexible pipe or pen container in the buckle-type that the securing device in the outside of securement head is, other are with embodiment 1.

Certainly, head 5 of the present utility model can be porous, single hole or hairbrush, and such change all drops within the protection domain of the present utility model.

Claims

1, a kind of flexible pipe anti-racking means, comprise flexible pipe or pen container, head and lid, it is characterized in that, flexible pipe or pen container front end internal fixation have a sleeve pipe, the sleeve pipe rear end connects a baffle plate, sleeve pipe has inlet point near on the sidewall of baffle plate, and the sleeve pipe other end place of sleeve pipe one end and close inlet point extends internally respectively and forms two cast projectioies; Head one end inserts inside pipe casing, its external diameter is identical with the internal diameter of 2 sleeve pipe projectioies of sleeve pipe, and there is a head projection in this head one end outside, is stuck between 2 sleeve pipe projectioies of sleeve pipe inboard, form one section space between head projection and the sleeve pipe projection, spring is housed in the middle of the space; Flexible pipe or pen container are provided with securing device in the outside of securement head, and lid is installed on flexible pipe or the pen container by securing device.
