The utility model discloses a telescopic pipe can extend when water pressure increases, and the outer tube does not have the fold, and material saving and appearance are pleasing to the eye, in addition, coupling assembling and inside and outside pipe can fast assembly and dismantlements, and the operation of being convenient for promotes the availability factor.
Description
Technical field
The utility model relates to a kind of pipe fitting, particularly a kind of telescoping tube.
Background technology
At present, telescoping tube mainly comprises inner and outer tubes, and inner tube is made up of elastomeric material, outside inner tube is arranged onGuan Zhong, the pipe table of outer tube arranges fold. In use, by stretching outer tube, fold launches, and makes outer tubeLength is elongated, thereby inner tube is extended. After finishing using, because making outer tube, receives the elastic-restoring force of inner tubeContracting, thus be convenient to storage. Existing telescoping tube defect is that outer tube will form fold, thereby needs moreMaterial, cost is higher; In addition, fold cannot launch completely, and development length is limited.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of corrugationless to produce, and saves materialAnd assembly and disassembly fast, telescoping tube easy to use.
Concrete technical scheme is as follows: a kind of telescoping tube, comprises inner tube, outer tube and coupling assembling, described inner tubeBe arranged in outer tube, described coupling assembling is arranged on telescoping tube two ends, and the length of described inner tube is identical with outer tube,The external diameter of inner tube is less than the external diameter of outer tube, and described inner tube is made up of elastomeric material, and described outer tube is by elastomeric nonwovenCloth is made, and described coupling assembling comprises Connection Block and guiding piece, and Connection Block inside is provided with hollow tube, inner tubeCan be set on hollow tube, hollow tube surrounding is provided with flexure strip, and guiding piece is located at outside pipe and by bulletProperty sheet is fixed.
It is below attached technical scheme of the present utility model.
As preferred version, described coupling assembling comprises fixture, and fixture is provided with internal thread, described companyJoint chair is provided with external screw thread, and fixture and Connection Block are threaded connection.
As preferred version, described fixture inside is provided with tapering point, and described tapering point can tighten up flexure strip.
As preferred version, described guiding piece one end is provided with introducing port, and it is horn-like that introducing port is.
As preferred version, the outer surface of described Connection Block is provided with limiting section, and limiting section is around Connection Block setting.
Technique effect of the present utility model: telescoping tube of the present utility model can extend in the time that hydraulic pressure increases, andOuter tube corrugationless, saves material and good looking appearance; In addition, coupling assembling and inner and outer pipe can rapid-assemblingsAnd dismounting, convenient operation, promotes service efficiency.

Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but thisUtility model is not limited to listed embodiment.
As shown in Figures 1 to 5, the telescoping tube 100 of the present embodiment comprises inner tube 1, outer tube 2 and coupling assembling3, described inner tube 1 is arranged in outer tube 2. Described coupling assembling 3 is arranged on telescoping tube 100 two ends, described inThe length of inner tube 1 is identical with outer tube 2, and the external diameter of inner tube 1 is less than the external diameter of outer tube 2, described inner tube 1 byElastomeric material is made, and described outer tube 2 is made up of elastic non-woven cloth. Described coupling assembling 3 comprises Connection Block 31With guiding piece 32, Connection Block 31 inside are provided with hollow tube 311, and inner tube 1 can be set in hollow tube 311On. Hollow tube 311 surroundings are provided with flexure strip 312, and it is outside and by flexure strip that guiding piece 32 is located at outer tube 2312 is fixing. In use, inner tube and outer tube can raise and stretch along with hydraulic pressure the telescoping tube of technique schemeLong, while use, can automatically shrink, meanwhile, the outer tube that adopts elastic non-woven cloth to make, makes the outer tube can be completeFull stretching, extension. In addition, adopt, flexure strip makes coupling assembling be connected with inside and outside body with guiding piece, is convenient to groupInstallation and dismantling are unloaded and stable connection.
As shown in Figures 1 to 5, further, described coupling assembling 3 comprises fixture 3, fixture 33Be provided with internal thread 331, described Connection Block 31 is provided with external screw thread 312, fixture 33 and Connection Block 31Be threaded connection, connect and can further promote assembling convenience by screw thread. Establish described fixture 33 insideHave tapering point 331, described tapering point 331 can tighten up flexure strip 312, thus rotation fixture in fromMove and tighten up flexure strip, realize Fast Installation. Described guiding piece 32 one end are provided with introducing port 321, introducing port 321Be horn-like, insert thereby be convenient to inner and outer tubes. The outer surface of described Connection Block 31 is provided with limiting section 313,Limiting section 313, around Connection Block setting, carries out spacing to fixture 33.
The telescoping tube of the present embodiment can extend in the time that hydraulic pressure increases, and outer tube corrugationless, saves material and outerShape is attractive in appearance; In addition, coupling assembling and inner and outer pipe can rapid-assembling and dismountings, convenient operation, and lifting makesUse efficiency.
The above is only preferred embodiment of the present utility model, it should be pointed out that for the artThose of ordinary skill, not departing under the prerequisite of the utility model principle, can also make some improvementAnd retouching, these improvements and modifications also should be considered as protection domain of the present utility model.
