Abstract
The utility model relates to a sealing hoop relating to a connection construction member generally used by pipelines. The utility model comprises a metal external shell, a spiral shaft, and a screw thread belt, wherein, the spiral shaft is placed in the metal external shell at first, and then, the spiral shaft and the metal external shell are fixed on the screw thread belt after the interaction between the buckling strips which are respectively arranged on the metal external shell and the screw thread belt. As a result, a locking buckle is formed. When the utility model is used, the tail end of the screw thread belt is inserted into the metal external shell so that external screw threads arranged on a screw bolt and the internal screw threads arranged on the screw thread belt are mutually jointed. Then, the spiral shaft is rotated, and the screw thread belt is screwed out of the metal external shell, and thereby, the internal diameter of the screw thread belt decreases as effective length decreases, and the tight looping role is played. The utility model has the advantages of beautiful appearance and convenient use. In particular, the characteristic of flexible, quick, and convenient use is exhibited more obviously when the construction of pipeline connection is carried out on working faces with limitation, wherein, the working faces with limitation comprise narrow port passages, dead corner positions, etc.
Description
Technical field
The utility model relates to pipeline commonly used and pipeline is refuted the construction part that connects usefulness.
Background technique
Refuting of existing water pipe and water pipe connects, and is be provided with screw thread in adopting one straight-through, has externally threaded water pipe and refutes and connect with two respectively.Rotate mutually combine with the outside thread of water pipe port by the internal thread on straight-through and link together, install so cumbersome, and usually not good enough because refute the construction effect that connects, and the phenomenon that appearance is seeped water, leaked.If fruit is refuted under the situation about connecing at hard tube and flexible pipe, inconvenience more when adopting such method of construction operation.
Summary of the invention
The utility model for address the above problem provide a kind of refute connect better performances, sealing is better, and sealing hoop easy to use, aesthetic in appearance.
Main technical schemes of the present utility model is: the sealing hoop comprises metal shell, screw axis, thread belt.Pack into metal shell the inside of screw axis then by after the profile on the metal shell and the interaction of the profile on the thread belt, two is fixed on it on thread belt, forms a snap close.
During use, rubber soft plastic pipe by a perforation links together two pipelines, enclose around one with the circumference of thread belt then along the rubber soft plastic pipe, then the tail end of thread belt is injected in the metal shell, outside thread on the screw axis and the internal thread on the thread belt are bonded with each other, form a ring-type.By external force rotating screw axle and thread belt is screwed out from metal shell, the internal diameter of thread belt will diminish along with reducing of effective length so then, thus with rubber soft plastic pipe lock ring on water pipe.The other end also with same method with rubber soft plastic pipe lock ring on water pipe, such two pipelines are just refuted and have been connected into an integral body.And soft plastic pipe made by polymer rubber section bar material, and it is splendid to make pipeline and pipeline refute the tightness that connects.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail:
Fig. 1 is an an embodiment's of the present utility model general illustration:
Fig. 2 is a combination assumption diagram of the present utility model:
Fig. 3 is a use schematic representation of the present utility model:
Fig. 4 is the structural representation of a kind of mode of execution of the present utility model:

Embodiment
As Fig. 1, Fig. 2, shown in Figure 3: screw axis 2 metal shell 3 the insides of packing into, after interacting by profile on the metal shell 38 and profile 5 on the thread belt then, it two is fixed on the thread belt 1, form a snap close.
As shown in Figure 4: behind above-mentioned mode of execution, adopt the rubber soft plastic pipe of a perforation that two water pipes are linked together, use sealing hoop then, circumference along the rubber soft plastic pipe encloses around one, and in the tail end of the thread belt 1 insertion metal shell 3, outside thread 6 on the screw axis 2 is bonded with each other with internal thread 4 on the thread belt, forms a ring-type.By external force rotating screw axle 2, the tail end of thread belt 1 will screw out from metal shell 3 step by step then, and crimp rubber soft plastic pipe gradually, makes rubber soft plastic pipe lock ring on water pipe; The other end also with same method with the soft plastic pipe lock ring on water pipe, refute and be connected into an integral body.Like this, two water pipes are just refuted and are connected together.
Shown in Figure 5: this embodiment connects for hard tube and refuting of flexible pipe, earlier hard tube is inserted in the rubber soft plastic pipe, adopts above-mentioned mode of execution to refute then and is connected into an integral body.Adopt above-mentioned said embodiment to use sealing hoop, this mode of execution is refuted the mode of execution that connects and is compared with existing, and more apparent it is easy to use, advantage efficiently.
