Abstract
The utility model relates to an expansion joint, its characterized in that: including inflation cover and expansion pipe, the inflation cover is including connecting portion and bulge, connecting portion are equipped with the internal thread, the expansion pipe includes that fixed part, press section and cover connect, the fixed part is equipped with the external screw thread, the press section is the toper, is equipped with bellied dog between its and cover connect, connecting portion overlap and the expansion pipe in order to be connected the inflation through interior matching the external screw with the fixed part. The utility model discloses the fine solution of expansion joint the connection problem between the metal pipeline such as shower curtain rod to have fine steadiness, the inner tube of connection and the phenomenon of outer tube disconnection can not appear in the use.
Description
Technical field
The utility model relates to a kind of piping attachment, is specifically related to a kind of expansion joint.
Background technique
Bath-curtain rod, refers to the telescopic supporting rod for hanging shower curtain, uses simple, low price, and it is convenient to change.Being generally an inner and outer pipes structure i.e. interior pipe puts in an outer tube, and in utilizing, button, spring or screw fix Bath-curtain rod, and then hanging up shower curtain, is the ideal in current humble abode epoch, solves narrow space and the random problem flown of spray.
At present, the interior pipe of the metallic conduit of similar Bath-curtain rod with mainly utilize between outer tube in detain, spring or screw carry out being connected, all there is certain problem in these interface units, for example, between interior pipe and outer tube, stable connection is poor, and Bath-curtain rod in use there will be separated the showing of inner and outer tubes.
Summary of the invention
For the problems referred to above, technical problem to be solved in the utility model is, provides a kind of expansion joint, and pipe in Bath-curtain rod can well be connected with between outer tube by it, has good steadiness.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of expansion joint, and its structural feature is, comprises expansion sleeve and expansion tube, and described expansion sleeve comprises joint and bulge, and described joint is provided with internal thread; Described expansion tube comprises fixing part, press section and bell and spigot joint, and described fixing part is provided with outside thread, and described press section is tapered, is provided with protruding block between itself and bell and spigot joint; Described joint coordinates to be connected expansion sleeve and expansion tube by internal and external threads with fixing part.
The utility model expansion joint, except being applied in except on Bath-curtain rod, can also being applied to the pipeline similar with Bath-curtain rod and being connected.In use, expansion tube in expansion joint is socketed on inner pipe by bell and spigot joint, then expansion sleeve is connected by the internal thread of joint and the outside thread of expansion tube fixing part, the bulge of such expansion sleeve will be corresponding with the press section of expansion tube, because press section is tapered, so the bulge of expansion sleeve will outwards expand.Then by outer tube sleeve on expansion joint, because the bulge on expansion sleeve is expanded gradually by the inside pipe direction of outer tube, the contact meeting more and more consolidation of outer tube and expansion joint, even can be expressed to expansion joint, applying expansion joint so just can by outer tube and firm the linking together of interior pipe.
Further, described joint is provided with guiding gutter, and described bulge is provided with breach and dilation is slit into two parts, and described breach is relative with guiding gutter.Joint being arranged guiding gutter is that gas when being squeezed by expansion joint is discharged, and makes interior pipe consistent with the air pressure of outer tube.And bulge is the part being subject to outer tube extruding, being divided into two-part can increase its frictional force with outer tube, and then steadiness when increasing expansion joint use.
Further, lines is provided with outside described bulge.The setting of lines herein is also the frictional force in order to increase bulge and outer tube, and then increases steadiness when expansion joint uses.
Further, described expansion joint adopts flexible plastic.
The utility model expansion joint well solves the connectivity problem between the metallic conduits such as Bath-curtain rod, and has good steadiness, in use there will not be the phenomenon that the interior pipe of connection and outer tube disconnect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model expansion sleeve structural representation.
Fig. 3 is the utility model expansion pipe structure schematic diagram.
Embodiment
By describe in detail the utility model technology contents, structure characteristics, reached object and effect, hereby exemplify embodiment below and coordinate accompanying drawing to be explained in detail.
Shown in Fig. 3, the utility model expansion joint is flexible plastic, and it comprises expansion sleeve 2 and expansion tube 1, and wherein, expansion sleeve 2 comprises joint 21 and bulge 22, and joint 21 is provided with internal thread; And expansion tube 1 comprises fixing part 12, press section 13 and bell and spigot joint 11, fixing part 12 is provided with outside thread, and it matches with the internal thread of joint 21, and press section 13 is tapered, is provided with protruding block between itself and bell and spigot joint 11.
The utility model expansion joint, except being applied in except on Bath-curtain rod, can also being applied to the pipeline similar with Bath-curtain rod and being connected.In use, expansion tube 1 in expansion joint is socketed on inner pipe by bell and spigot joint 11, then expansion sleeve 2 is connected by the internal thread of joint 21 and the outside thread of expansion tube 1 fixing part 12, the bulge 22 of such expansion sleeve 2 will be corresponding with the press section 13 of expansion tube 1, because press section 13 is tapered, so the bulge 22 of expansion sleeve 2 will outwards expand.Then by outer tube sleeve on expansion joint, because the bulge on expansion sleeve 2 is expanded gradually by the inside pipe direction of outer tube, the contact meeting more and more consolidation of outer tube and expansion joint, even can be expressed to expansion joint, applying expansion joint so just can by outer tube and firm the linking together of interior pipe.
Continue with reference to the expansion sleeve 2 shown in Fig. 2, its joint 21 is provided with guiding gutter 211, and bulge 22 is provided with breach 221 and bulge 22 is divided into two parts, and this breach 221 is relative with guiding gutter 211.Joint 21 being arranged guiding gutter 211 is that gas when being squeezed by expansion joint is discharged, and makes interior pipe consistent with the air pressure of outer tube.And bulge 22 is the parts being subject to outer tube extruding, being divided into two-part can increase its frictional force with outer tube, and then steadiness when increasing expansion joint use.In order to ensure the steadiness of expansion joint further, set up lines in the outside of bulge 22.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalence changes done according to the utility model the scope of the claims and description with modify, be all within scope that the utility model patent contains.
