Abstract

A detachable connector for pipe fittings comprises a connector body, and a gland is connected outside the connector body through threads. The detachable connector for pipe fittings is characterized in that a step is manufactured on the inner wall of the connector body; an expansion fixing part is arranged on the step, a conical surface inclined outward is manufactured on the outer wall of the expansion fixing part; a chamfered surface inclined outward is manufactured on the inner wall of the gland and is matched with the conical surface; and an inverted buckle is arranged on the inner wall of the expansion fixing part and is used for clamping a plastic pipe. The utility model adopts the scheme that the outer part of the connector body is in threaded connection, and the expansion fixing part arranged inside the connector body retracts and clamp under pressure, so that the plastic pipe does not come off; and the detachable connector is mounted quickly, dismounted easily and replaced conveniently, and has simple structure and good sealing performance.

Description

Removable pipe fitting joint
Technical field
The utility model relates to a kind of removable pipe fitting joint, belongs to the plastic pipe technical field.
Background technique
Existing plastic pipe joint generally adopts hot melt to connect or is threaded, and the shortcoming that hot melt connects is can not dismantle after connecting, and maintenance is inconvenient; The two ends that mainly are included in pipe fitting joint that are threaded are shaped on internal thread, be attached thereto the tubing end that connects and be shaped on outside thread, both directly are threaded, and seal with stuffing such as greasy filth, fibers in the threaded connection place, install, dismantle trouble, labor intensity is big; And this Placement produces corrosion easily in the threaded connection place, and sliding dental phenomenon often takes place in very inconvenience when dismounting or maintenance.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of simple in structure, easy to loading and unloading, the removable pipe fitting joint of good seal performance.
The technological scheme of the removable pipe fitting joint of the utility model is: comprise joint body, joint body is outer through the gland that is threaded, it is characterized in that described joint body inwall is shaped on step, the expansion fixed block is set on the step, the outer wall of expansion fixed block is made the conical surface of outer incline, and the inwall of gland is made the scarf of outer incline, and scarf matches with conical surface, be shaped on back-off on the inwall of expansion fixed block, back-off blocks plastic tube.
Removable pipe fitting joint of the present utility model, described joint body inwall is shaped on step, the expansion fixed block is set on the step, the outer wall of expansion fixed block is made the conical surface of outer incline, the inwall of gland is made the scarf of outer incline, scarf matches with conical surface, is shaped on back-off on the inwall of expansion fixed block, and back-off blocks plastic tube.During installation plastic tube is inserted in the expansion fixed block, expansion fixed block overcoat gland, again the expansion fastener tapes tubing is inserted in the joint body, gland is tightened through screw thread with joint body and is connected, in the process of tightening, expansion fixed block pressurized shrinks, and the chucking plastic tube can not come off plastic tube.The outside employing of this programme is threaded, and inner employing expansion fixed block pressurized shrinks the chucking mode, and plastic tube can not come off, and quick for installation, dismounting is changed conveniently easily, and simple in structure, good seal performance.
Removable pipe fitting joint of the present utility model is provided with seal ring between the step of described expansion fixed block and joint body, seal ring has been arranged, good seal performance.Described expansion fixed block is the opening cutting ferrule, when the inwall of gland with after the outer wall of opening cutting ferrule contacts, cutting ferrule opening pressurized shrinks, and plastic tube is blocked.
Description of drawings
Fig. 1 is a removable pipe fitting joint structural representation of the present utility model;
Fig. 2 is that expansion fixed block of the present utility model cooperates schematic representation with gland;
Fig. 3 is that expansion fixed block of the present utility model is an opening cutting ferrule schematic representation.
Embodiment
The utility model relates to a kind of removable pipe fitting joint, as shown in Figure 1-Figure 3, comprise joint body 1, joint body 1 is outer through screw thread 2 connection glands 3, it is characterized in that described joint body 1 inwall is shaped on step 4, expansion fixed block 5 is set on the step, the outer wall of expansion fixed block is made the conical surface 51 of outer incline, and the inwall of gland 3 is made the scarf 31 of outer incline, and scarf 31 matches with conical surface 51, be shaped on back-off 52 on the inwall of expansion fixed block 5, back-off 52 blocks plastic tube 6.During installation plastic tube 6 is inserted in the expansion fixed block 5, expansion fixed block 5 overcoat glands 3, again expansion fixed block 5 is being with tubing 6 to be inserted in the joint body 1, gland 3 is tightened through screw thread 2 with joint body 1 and is connected, in the process of tightening, expansion fixed block 5 pressurizeds shrink, and chucking plastic tube 6 can not come off plastic tube 6.The outside employing of this programme is threaded, and inner employing expansion fixed block pressurized shrinks the chucking mode, and plastic tube can not come off, and quick for installation, dismounting is changed conveniently easily, and simple in structure, good seal performance.Be provided with seal ring 7 between the step 4 of described expansion fixed block 5 and joint body 1, seal ring arranged, good seal performance.Described expansion fixed block 5 is an opening cutting ferrule 8, when the inwall of gland with after the outer wall of opening cutting ferrule contacts, cutting ferrule opening pressurized shrinks, and plastic tube is blocked.
