Abstract
The utility model relates to a pipe joint, comprising a connecting piece. The front end of the connecting piece is provided with a hollow fastening bolt, and the inner side of the connecting piece is provided with a locking hoop; the inner side of the locking hoop is provided with an inward inclined end face; the connecting piece on the inner side of the end face is provided with a locking sleeve, a deformation gasket and an elastic sealing ring; when the pipe joint is used, the hollow fastening bolt is tightly screwed to cause the locking sleeve to be extruded between the outer wall of a pipe and the locking hoop and to cause the elastic sealing ring to deform to obtain the purposes of connecting and sealing the pipe. The utility model solves solve the disadvantages of sleeving threads on the pipe during installation, inconvenient installation, large labor intensity and low work efficiency in the prior art.
Description
The utility model relates to a kind of pipe joint.
Existing pipe joint comprises all that usually an internal surface is provided with the link of screw thread, by die head threading machine screw thread on the tube end headgear that needs connect, then pipe and link is fitted together, to reach the purpose of connecting pipeline during installation.Its shortcoming has two: one, rotates inconveniently when some pipe joints is installed, and also there is the direction requirement last mounting point, but generally during construction difficultly reaches the direction requirement of both satisfying the mounting point, and screw thread is tightened; The 2nd, die head threading machine need be taken to the job site and carry out mantle fiber, labor intensity is increased, working efficiency reduces.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and does not need when a kind of the installation is provided to require and the fast holding pipe joint that is connected the pipe seal request connecting mantle fiber on the pipe and rotate direction convenient, that satisfy the mounting point easily.
For finishing above-mentioned purpose, the utility model provides a kind of fast holding pipe joint, it comprises a link, its special way is, the inwall of this link is provided with an intilted end face, the front end of link is equipped with a hollow clamping bolt, a locking strap is equipped with in its inboard, the inwall of locking strap also is provided with an intilted end face, a lock sleeve is respectively installed in above-mentioned two intilted end face inboards, the inboard of lock sleeve respectively is provided with a distortion packing ring, between two distortion packing rings an elastic seal ring is housed.
For finishing the purpose of foregoing invention, another fast holding pipe joint that the utility model provides also comprises a link, its special way is: the inwall of this link is provided with a platform, the front end of link is equipped with a hollow clamping bolt, a locking strap is equipped with in its inboard, the inwall of this locking strap is provided with an intilted end face, lock sleeve of the installed inside of this end face, the inboard of lock sleeve is provided with a distortion packing ring, and an elastic seal ring is installed between distortion packing ring and the described platform.
Lock sleeve in above-mentioned two kinds of fast holding pipe joints can be the cone locking cover, also can be the cylindrical shape locking cover of being made by sheet metal.
Lock sleeve in above-mentioned two kinds of fast holding pipe joints can link together with the distortion packing ring.Locking strap can link together with hollow clamping bolt, and the front-end face that is about to hollow clamping bolt is made an intilted end face.
Fig. 1 is the utility model first embodiment's a structural representation;
Fig. 2 is the utility model second embodiment's a structural representation;
Fig. 3 is the structural representation after second embodiment uses.
Know with reference to Fig. 1, this fast holding pipe joint has a link 1, the inwall of this link 1 is provided with an intilted end face 2, the front end of link 1 is equipped with a hollow clamping bolt 10, a locking strap 9 is equipped with in its inboard, the inwall of locking strap also is provided with an intilted end face 8, a cone locking cover 3,7 is respectively installed in above-mentioned two intilted end face inboards, the inboard of lock sleeve is provided with a distortion packing ring 4 and 6 respectively, between these two distortion packing rings an elastic seal ring 5 is housed.
With reference to Fig. 2 as can be known, this second embodiment also has a link 1, hollow clamping bolt 10, locking strap 9, cone locking cover 7, distortion packing ring 6 and elastic seal ring 5, but it does not have the cone locking cover 3 among the embodiment 1, distortion packing ring 4 and the intilted end face 2 that is located at link 1 inwall, described seal ring 5 directly is positioned on the platform 11 of being located in the link 1.
With reference to Fig. 3, in the pipe 12 direct insertion tube joints that will need during use to connect, tighten hollow clamping bolt 10 with instrument, locking strap 9 will move forward under the thrust of hollow clamping bolt, cone locking cover 7 will at first be squeezed between the inwall of the outer wall of pipe 12 and locking strap 9, distortion packing ring 6 also will deform and make elastic packing distortion simultaneously and will seal between the outer wall of pipe 12 and the pipe joint, can reach like this to connect and the purpose of sealing.
In conjunction with the foregoing description as can be seen, the utility model has following advantage compared to existing technology:
Can directly pipe be inserted link when 1, installing, need not be used in mantle fiber on the pipe, save the work of carrying die head threading machine, labor intensity is reduced, working efficiency improves;
2, pipe can be coupled together by tightening hollow clamping bolt, not need turne tube or link, easy for installation, and can fully satisfy the direction requirement of pipe joint mounting point;
3, the elastic seal ring after the distortion is close to tube wall, thereby sealing is fine;
4, clamp ring is squeezed between the inwall of tube outer wall and pipe joint, has not only increased the compressive strength after pipe joint connects, and has made difficult becoming flexible between pipe and the pipe joint, can reach rigidly connected purpose.
Claims (4)
