Description
Technical field
The utility model relates to a kind of water pipe adapter, more specifically refers to
a kind of expansion joint.
Background technique
Water pipe is the pipeline of water supply, be seen everywhere in daily life, water pipe also has rigidity and flexibility etc. multiple, the problem needing water pipe to lengthen often is run in life, particularly basin, the water tap of the positions such as washbowl, length due to water pipe just reserves when mounted, when running into toward utensil filled with water higher than water tap of bucket or kettle equal altitudes, need to adopt flexible pipe to connect in addition, or add water toward other places, and need water pipe to have good rigidity, and market can only have been bought usually flexible pipe or the leather hose of ripple, the requirement of rigidity cannot be met.
Summary of the invention
Main purpose of the present utility model is to provide and solves above-mentioned Problems existing, a kind of expansion joint is provided, it is by structure improvement, interior pipe and outer tube is docking together fast by folder bundle device, and interior pipe can freely at this outer in-pipe and stable position.
An object more of the present utility model be to provide a kind of safe and reliable, simple expansion joint is installed.
The technical solution adopted in the utility model is: a kind of expansion joint, comprise outer tube, movable insertion is connected on the interior pipe of this outer tube and departs from the folder bundle device of this outer tube for limiting this interior pipe, one end of this outer tube is provided with trumpet-shaped clasp, the middle part of this interior pipe is provided with limited part, this interior pipe of this limited part side is provided with at least one groove, seal ring is provided with in this groove, this folder bundle device comprises the slip ring on this interior pipe of this limited part opposite side of pivot bush unit, be fixed on the folder bundle part outside slip ring and be arranged on the elastic buckles component for fastening this clasp of this folder bundle part inside.
Number of recesses on this interior pipe is two, and the quantity of seal ring is two.
This slip ring is provided with for the fixing draw-in groove of this folder bundle part.
This outer tube is provided with the skew wall for preventing interior pipe from departing from relative to the other end of this clasp.
The beneficial effects of the utility model are: the utility model structurally comprises outer tube, movable insertion is connected on the interior pipe of this outer tube and departs from the folder bundle device of this outer tube for limiting this interior pipe, one end of this outer tube is provided with trumpet-shaped clasp, the middle part of this interior pipe is provided with limited part, this interior pipe of this limited part side is provided with at least one groove, seal ring is provided with in this groove, this folder bundle device comprises the slip ring on this interior pipe of this limited part opposite side of pivot bush unit, be fixed on the folder bundle part outside slip ring and be arranged on the elastic buckles component for fastening this clasp of this folder bundle part inside.It is by structure improvement, interior pipe and outer tube is docking together fast by folder bundle device, and interior pipe can freely at this outer in-pipe and stable position.And the utility model have safe and reliable, simple feature is installed.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Be illustrated in figure 1 one of the present utility model preferably specific embodiment, a kind of expansion joint, comprise outer tube 10, movable insertion is connected on the interior pipe 20 of this outer tube 10 inside and departs from the folder bundle device 30 of 20 these outer tubes 10 for limiting this interior pipe, one end of this outer tube 10 is provided with trumpet-shaped clasp 11, the middle part of this interior pipe 20 is provided with limited part 21, this interior pipe 20 of this limited part 21 side is provided with at least one groove 22, seal ring 221 is provided with in this groove 22, this folder bundle device 30 comprises the slip ring 31 on this interior pipe 20 of this limited part 21 opposite side of pivot bush unit, be fixed on the folder bundle part 32 outside slip ring 31 and be arranged on the elastic buckles component 33 for fastening this clasp 11 of this folder bundle part 32 inside.
Further, groove 22 quantity on this interior pipe 20 is two, the quantity of seal ring 221 is two, the space between this interior pipe 20 and this outer tube 10 is filled by seal ring 221, while preventing the liquid (tap water) entered in pipe from overflowing, can stable position after increase damping function impels interior pipe to move.
Further, this slip ring 31 is provided with for the fixing draw-in groove 311 of this folder bundle part 32.
In the process made, the caliber of limited part 21 side (that side for docking with outer tube enclosure) is greater than the caliber of opposite side (that side that slip ring is socketed), and to make both there is certain drop in periphery, this drop is above-mentioned limited part.
This elastic buckles component is spring.
By the existence of this limited part, prevent interior pipe 20 from departing from outer tube, namely the position-limiting action of this limited part is subject to, after elastic buckles component 33 fastens this outer tube, because slip ring cannot by the opposite side of limited part, therefore in realizing, pipe can do fore and aft motion within the specific limits in outer tube, and prevent interior pipe from departing from outer tube, and due to folder bundle device energy fast fastening, while therefore the utility model realizes stretching, also add Security, prevent interior pipe from departing from outer tube and the hidden danger that causes.
It is worth mentioning that, this outer tube 10 is provided with the skew wall 12 for preventing interior pipe from departing from relative to the other end of this clasp 11, and the effect of skew wall 12 is similar with the effect of limited part, is all for preventing interior pipe from an other landing of outer tube.
Embodiment of the present utility model and accompanying drawing are just in order to show design concept of the present utility model, and protection domain of the present utility model should not be confined to this embodiment.
By above describe can find out that purpose of design of the present utility model can effectively be implemented.The portion shows of embodiment the purpose of this utility model and implement function and structure theme, and comprise other equivalent replacement.
Therefore, right of the present utility model forms the equivalence comprising other and implements, concrete right range reference claim.
