Abstract
An insert-type self-locking fast tube joint and a disassembling tool matched with same belong to the tube connecting and tube disassembling fields. The insert-type self-locking fast tube joint is characterized in that rubber sealing rings, a drum-shaped tube locking device with inner teeth and an inner supporting tube having outer wall with concave and convex stoppers are arranged in a tube joint shell, a dustproof guide plug bush is arranged at a throat of the tube joint, wherein the dustproof duct plug bush can be pulled out of the tube joint shell, injector blocks of the disassembling tool can be inserted into the tube joint shell to shove away the teeth of the tube locking devices so as to push a connected tube out; the bottom of the inner surface of the tube joint shell is fixedly integrated with the tail of the inner supporting tube, and the quantity of the inner supporting tube is determined according to materials of the connected tube. The disassembling tool matched with the insert-type self-locking fast tube joint comprises handles, the rigid ejector blocks, disassembling teeth and a shrinkage controlling switch. The problems of high requirements for labor, time and environmental condition of the jointing work and the non-reusability of the joint when the tube joint is used for connecting tubes of different materials are solved. By the aid of the tube joint with sealing and self-locking functions and the disassembling tool matched with the same, tubes can be assembled and dissembled in a fast and convenient way.
Description
Technical field
The present invention relates to connection, dismounting devices field, the insertion self-locking pipe joint of various hard tubing of a kind of specifically quick connection or soft tubing and the supporting piping tool that unloads thereof of various material tubing.
Background technique
At present, the Placement of various material tubing roughly has bayonet joint, clamp-press type connection, clamp band type connection, thread type connection, hot melten type connection, veneer type connection etc.Above-mentioned any Placement all requires highly to construction environment, need the professional and technical personnel to pass through the special tool operation, has complex operation, time-consuming, and the human operational error is prone to the shortcoming that causes tie point to leak, leak gas; The various pipe joints of the above Placement also can't connect soft tubing easily, and majority can't be reused.
Summary of the invention
The present invention is loaded down with trivial details, time-consuming for the connection, the disassembling section that solve present various tubing; Pipe joint can't be reused; The problem that can not conveniently connect soft tubing; A kind of sealing and auto lock structure of having is provided, installation and removal simply, connecting tube joint and the supporting piping tool that unloads thereof efficiently.
Technological scheme of the present invention is; A kind of insertion self-locking pipe joint that can connect various hard or soft tubing fast reaches the unload piping tool supporting with it; Comprise the pipe joint housing; Rubber seal, barrel shaped internal tooth lock pipe arrangement and the concavo-convex interior stay tube that stops of outer wall belt are arranged in the pipe joint housing, and closing in place of pipe joint housing has dustproof conduit plug sleeve.Its special way is that pipe joint shell inner surface bottom and interior stay tube tail end under the ring-like extruding of machinery, fasten as one pipe joint housing and interior stay tube the concavo-convex blocking teeth of front end outer wall belt of interior stay tube; Barrel shaped internal tooth lock pipe arrangement becomes barrel shaped, and cylindrical shell one end has 2-3mm to cylindrical shell heart bending 90 degree, forms circular back-up ring; The cylindrical shell and the internal tooth tooth root portion of lock pipe arrangement connect as one, and internal tooth has certain inclination angle towards the reel heart with the reel inwall; There are the teeth that bend inwards at internal tooth crown position, and the lock pipe arrangement has the above internal gear winding reel inwall of two rows, and respectively arranges internal tooth and be staggered; Teeth directional is consistent; Towards circular back-up ring, the outer wall of barrel shaped internal tooth lock pipe arrangement is parallel with the pipe joint housing, directly is close to the pipe joint inner walls; Dustproof conduit plug sleeve can be pulled out the pipe joint housing, gives the jacking block slot milling that unloads piping tool, in the jacking block slip insertion tube joint housing, pushes the teeth of the lock pipe arrangement that vises outer pipe wall open, thereby extracts tubing.
The present invention provide simultaneously with connection set supporting unload piping tool; Comprise lever, hard jacking block, tear tooth and undergauge control switch open, it is characterized in that two levers are nearly semicircle, joining through connection axis of a cylinder 1 links together; Two levers and two semicircular hard jacking blocks and two semicircular teeth of tearing open are connected as a single entity; Lever and hard jacking block, tearing tooth open can be along being connected axis of a cylinder 1 opening and closing, and the undergauge control switch is joined with one of them lever and linked together through connecting axis of a cylinder 2, opens the undergauge control switch; The lever of holding with a firm grip can dwindle and unload two formed round internal diameters of semicircle hard jacking block of piping tool.
Technique effect of the present invention is; Adopt technique scheme can realize a kind of easy and simple to handle, connect fast; Simple in structure, can reuse, can conveniently connect the pipe joint of hard or soft tubing; It has overcome the pipe joint of existing unlike material when connecting tubing; The technical sophistication that exists, to construction environment require high, time-consuming, need shortcoming such as special tool, suit is in copper pipe, Stainless Steel Tube, aluminum pipe, the connection of various material tubing such as plastics class AGR, PPR, PE, PVC and plastic-aluminum tubing use.
