Abstract

The utility model relates to a pipeline pressing quick-changing connector which solves the problems that in the existing pipeline pressing connection mode, operation is complex, and production efficiency is low. The pipeline pressing quick-changing connector comprises a connector body, a rubber conical sleeve, a locking nut, a clamping hoop and a hose. The outer circle of the rubber conical sleeve is of a conical structure, the diameter of the small end of the rubber conical sleeve is smaller than the size of an inner hole of a pipeline, the diameter of the big end of the rubber conical sleeve is larger than the size of the inner hole of the pipeline, and the inner hole of the rubber conical sleeve is matched with the connector body. A step for limiting the small end of the rubber conical sleeve is arranged at the front end of the connector body, and the locking nut is screwed on the connector body close to the big end of the rubber conical sleeve. When the locking nut moves left and right along threads on the connector body, pressing and loosening of the rubber conical sleeve can be achieved, and the connector body is connected with a pressure source through the clamping hoop and the hose. The pipeline pressing quick-changing connector is high in universality, convenient to operate, and high in replacement speed, and improves production efficiency.

Description

Pipeline is suppressed quick change joint
Technical field
The utility model relates to a kind of joint, is specifically related to a kind of pipeline and suppresses quick change joint.
Background technique
Conventionally when the welding pipeline of conveying liquid or gas is suppressed, pressure source is connected the main flexible pipe that adopts and connects with pipeline, then with clip, flexible pipe is fastening, and the blank pipe of especially usining uses more frequent as this Placement of pipeline of connecting end.When suppressing pipeline external diameter specifications vary, must change the flexible pipe of dimension, cost of production is relatively high; On the other hand, this Placement replacing operates more loaded down with trivial details while suppressing pipeline, and manufacturing efficiency is lower.
Summary of the invention
The utility model has solved current pipeline, and to suppress the operation existing in Placement more loaded down with trivial details, the problem that manufacturing efficiency is lower.
The utility model is realized by following technological scheme:
A kind of pipeline is suppressed quick change joint, comprise fittings body, rubber tapered sleeve, locking nut, clip and flexible pipe, rubber tapered sleeve cylindrical is cone structure, end diameter is less than the interior hole dimension of pipeline, Outside diameter is greater than the interior hole dimension of pipeline, rubber tapered sleeve endoporus coordinates with fittings body, fittings body front end is with to the spacing step of rubber tapered sleeve small end, near on the fittings body of the large end of rubber tapered sleeve, be screwed with locking nut, when locking nut moves left and right along the screw thread on fittings body, can realize the compression of rubber tapered sleeve and unclamp, fittings body is connected with pressure source with flexible pipe by clip.
Fittings body and pressure source connection part structure are back taper structure.
This welding pipeline quick change joint positions with pipeline endoporus, adopt the rubber sleeve that cylindrical is tapering to coordinate with pipeline endoporus, play the effect of sealing and protection pipeline, the cross section of the conical distribution of rubber tapered sleeve can adapt to the variation of pipeline diameter in certain limit simultaneously; Small end at rubber sleeve is spacing with fittings body step, when locking nut applies end thrust along fittings body axis to the large end of rubber tapered sleeve, rubber tapered sleeve deforms, it is large that the radial dimension of the conical surface becomes, and after coordinating with pipeline inner wall, the rubber deformation of contact position is restricted, blank pipe inwall is produced to radial pressure, guarantee that rubber tapered sleeve and blank pipe produce enough frictional force to maintain coupled condition, form high pressure sealing band simultaneously, guarantee sealing effect.When needs disconnect, locking nut to be unscrewed, rubber tapered sleeve resiles naturally, and this joint and pipeline are directly disconnected.
The utility model is owing to taking above technological scheme, and it has the following advantages:
(1) this welding pipeline quick change joint structure is reasonable, reliable, the applicable pipeline specification limit of sealing is wide, and versatility is stronger, and cost of production is lower.
(2) when this welding pipeline quick change joint is that blank pipe connects, easy to operate, change speed, improved manufacturing efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises fittings body 2, rubber tapered sleeve 3, locking nut 4, clip 5 and flexible pipe 6.Rubber tapered sleeve 3 cylindricals are cone structure, end diameter is less than the interior hole dimension of pipeline 1, Outside diameter is greater than the interior hole dimension of pipeline 1, relies on the specifications vary of the variation adaptation pipeline 1 of tapering, and rubber tapered sleeve 3 can be realized according to the variation of pipeline specification the coupling of different taperings simultaneously; Rubber tapered sleeve 3 endoporus coordinate with fittings body 2, and the step of fittings body 2 front ends is spacing to the small end of rubber tapered sleeve 3, and large end is spacing by locking nut 4, when locking nut 4 moves left and right along the screw thread on fittings body 2, can realize the compression of rubber tapered sleeve 3 and unclamp; On locking nut 4, be designed with reticulate pattern and tool lock tieholen, in the time of can connecting according to reality, the size of pressure source is carried out choice for use; Back taper structure on fittings body 3 is connected with pressure source with flexible pipe 6 by clip 5.During actual use, first rubber tapered sleeve 2 small ends of this welding pipeline quick change joint are inserted in the endoporus of pipeline 1, then rotation lock nut 4 makes its large end that compresses rubber tapered sleeve 2, after 3 distortion of rubber tapered sleeve, is connected with pipeline 1, when needs disconnect, counter-rotation locking nut.

Claims (2)

1. a pipeline is suppressed quick change joint, it is characterized in that: comprise fittings body, rubber tapered sleeve, locking nut, clip and flexible pipe, rubber tapered sleeve cylindrical is cone structure, end diameter is less than the interior hole dimension of pipeline, Outside diameter is greater than the interior hole dimension of pipeline, rubber tapered sleeve endoporus coordinates with fittings body, fittings body front end is with to the spacing step of rubber tapered sleeve small end, near on the fittings body of the large end of rubber tapered sleeve, be screwed with locking nut, when locking nut moves left and right along the screw thread on fittings body, can realize the compression of rubber tapered sleeve and unclamp, fittings body is connected with pressure source with flexible pipe by clip.
2. a kind of pipeline according to claim 1 is suppressed quick change joint, it is characterized in that: fittings body and pressure source connection part structure are back taper structure.
