Abstract
The utility model discloses an annular corrugated pipe, which comprises a corrugated pipe body, a connection pipe arranged at one end of the corrugated pipe body, external threads arranged at the outer side of the connection pipe, a spoiler arranged at the inner side of the connection pipe and arranged for an annular array, a positioning ring arranged at one end of the side surface of the connection pipe, a first sealing ring arranged on the positioning ring, a connection sleeve arranged at the other end of the corrugated pipe body, a second sealing ring arranged at one end inside the connection sleeve, and internal threads arranged at the inner side of the connection sleeve; a sealing glue layer is coated on the external thread; through the synergism of spoiler and external screw thread, after the bellows body lets in fluid, refute and connect the pipe and produce the torque under spoiler and fluid effect to make internal thread and external screw thread contact inseparabler, and make the sealant layer distribute more evenly between internal thread and external screw thread, thereby improve the leakproofness of refuting and connecting.
Description
Technical Field
The utility model relates to a bellows field, concretely relates to annular bellows.
Background
In the use of the prior corrugated pipe for transporting and infusing liquid, the corrugated pipe is often required to be used for a long distance, so that a plurality of sections of corrugated pipes are required to be connected in series for use, in the prior nonmetal corrugated pipe, the corrugated pipes are usually connected by directly rotating threads, and the sealing of the corrugated pipes is realized by utilizing the threaded connection, but because the production errors of the corrugated pipes and the like are caused, the threaded connection on the corrugated pipes is not tight enough, and the liquid is easily polluted due to the liquid leakage or the external liquid infiltration.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing an annular bellows that has simple structure, connection stability height, the leakproofness is good and improve life.
In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides an annular corrugated pipe, includes the bellows body, sets up the refute of bellows body one end connects the pipe, sets up refute the external screw thread in the takeover outside, set up refute take over inboard, and be the spoiler that the annular array set up, set up refute the holding ring of pipe side one end, set up and be close to on the holding ring the first sealing washer of external screw thread one side sets up refute the cover of bellows body other end, set up and be in refute the second sealing washer of the inside one end of cover, and set up and be in refute the inboard internal thread of cover.
Preferably, the external thread is coated with a sealant layer.
Preferably, the spoiler is disposed obliquely.
Preferably, the corrugated pipe body is a high-density polyethylene pipe body.
Preferably, the diameter of the docking sleeve is larger than the diameter of the docking tube.
Preferably, the diameter of the first seal ring is larger than the diameter of the second seal ring.
The utility model discloses technical effect mainly embodies: through the synergistic effect of the spoiler and the external thread, after the corrugated pipe body is filled with fluid, the connection pipe generates torque under the action of the spoiler and the fluid, so that the internal thread is in closer contact with the external thread, the sealing glue layers are more uniformly distributed between the internal thread and the external thread, the connection tightness and stability are improved, the sealing performance is further improved by matching the first sealing ring and the second sealing ring, and the service life of the corrugated pipe is prolonged; therefore, the connecting structure has the advantages of simple structure, high connecting stability, good sealing performance and prolonged service life.

Fig. 1 is a structural diagram of an annular corrugated pipe according to the present invention;
fig. 2 is a schematic connection diagram of the annular corrugated tube of the present invention.
Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.
The utility model provides an annular corrugated pipe, as shown in fig. 1-2, including bellows body 1, set up refute the pipe 2 that connects of bellows body 1 one end, set up refute the external screw thread 3 in the takeover 2 outside, the coating has the sealant layer 31 on the external screw thread 3 for improve the leakproofness between internal thread 9 and the external screw thread 3, set up refute take over 2 inboard and for the spoiler 4 that the annular array set up, spoiler 4 is the slope setting for after letting in fluid, utilize the torque that fluid produced to spoiler 4 to make between internal thread 9 and the external screw thread 3 inseparabler, be convenient for sealant layer 31 evenly distributed between internal thread 9 and external screw thread 3, still improved the structural strength who refutes takeover 2, set up refute the holding ring 5 of takeover 2 side one end, set up in the holding ring 5 be close to the first sealing washer 6 of external screw thread 3 one side, the setting is in refuting of the 1 other end of bellows body connects cover 7, sets up refute the second sealing washer 8 of the inside one end of connecting cover 7 for cooperation sealing glue layer 31 and first sealing washer 6 further improve the leakproofness, and set up and be in refute the internal thread 9 of connecting cover 7 inboard.
The utility model discloses technical effect mainly embodies: through the synergistic effect of the spoiler and the external thread, after the corrugated pipe body is filled with fluid, the connection pipe generates torque under the action of the spoiler and the fluid, so that the internal thread is in closer contact with the external thread, the sealing glue layers are more uniformly distributed between the internal thread and the external thread, the connection tightness and stability are improved, the sealing performance is further improved by matching the first sealing ring and the second sealing ring, and the service life of the corrugated pipe is prolonged; therefore, the connecting structure has the advantages of simple structure, high connecting stability, good sealing performance and prolonged service life.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
