Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example (b): referring to fig. 1 and 2, for the utility model discloses a connecting pipe fitting for pipe connection, including connecting piece inside lining 1. The end of the connecting piece lining 1 is set to be an inclined chamfer, and the diameter of the connecting piece lining 1 at the position of the chamfer is smaller than the inner diameter of the connecting pipeline 3, so that the connecting piece lining 1 can penetrate into the connecting pipeline 3 more conveniently. Fixedly connected with base 2 (base 2 and connecting piece inside lining 1 integrated into one piece) is gone up to connecting piece inside lining 1, and the cover is worn to have connecting tube 3 in the one end that connecting piece inside lining 1 kept away from base 2.
Referring to fig. 2 and 3, in order to more stably wear the connecting pipe 3 and the connector liner 1 together, the sealability between the connecting pipe 3 and the connector liner 1 is improved. Therefore, the outer side wall of the connector liner 1 is fixedly connected with a limit flange 44 (the limit flange 4 and the connector liner 1 are integrally formed), the limit flange 4 is annular, and the limit flange 4 and the connector liner 1 are coaxially arranged. Connecting tube 3's inside wall is opened there is spacing groove 5, and spacing groove 5 is provided with two at connecting tube 3's inside wall, and two spacing grooves 5 set up about connecting tube 3's central axis symmetry, and spacing post 6 has been slided to wearing in the spacing groove 5. The position of the limiting column 6 close to the opening end of the connecting pipeline 3 is set to be an inclined arc surface, the bottom of the limiting groove 5 is welded with a pressure spring 7, and the pressure spring 7 is extruded between the limiting column 6 and the limiting groove 5.
Referring to fig. 2 and 3, an operator penetrates the connecting piece lining 1 into the connecting pipe 3 from one end of the connecting pipe 3, the limiting flange 4 extrudes the limiting column 6, and the pressure spring 7 retracts into the limiting groove 5 under pressure. At this moment, connecting piece inside lining 1 wears to overlap in connecting tube 3, and the reaction force that pressure spring 7 produced makes spacing post 6 support tightly at the lateral wall of connecting piece inside lining 1, and spacing flange 4's setting plays spacing effect to spacing post 6, has reduced connecting tube 3 and has received and has rocked, takes place connecting piece inside lining 1 and breaks away from the phenomenon that comes out from connecting tube 3.
Referring to fig. 2 and 3, since the connector liner 1 may penetrate into the connection pipe 3, a gap exists between the outer sidewall of the connector liner 1 and the connection pipe 3. Therefore, an annular flange 8 is fixedly connected to the outer peripheral wall of the connecting piece lining 1 (the annular flange 8 and the connecting piece lining 1 are integrally formed), the diameter of the annular flange 8 is larger than that of the connecting piece lining 1, a sealing groove 9 is formed in the outer side wall of the annular flange 8, the sealing groove 9 is annularly formed along the outer side wall of the annular flange 8, and a sealing ring 10 is placed in the sealing groove 9. When the connecting piece lining 1 is sleeved in the connecting pipeline 3 in a penetrating manner, the sealing ring 10 in the sealing groove 9 is tightly abutted to the inner side wall of the connecting pipeline 3, the sealing ring 10 plays a role in sealing a gap between the connecting piece lining 1 and the connecting pipeline 3, and the sealing property between the connecting pipeline 3 and the connecting piece lining 1 is further improved.
Referring to fig. 3 and 4, the outer side wall of the annular flange 8 is fixedly connected with the anti-slip threads 11 (the anti-slip threads 11 are integrally formed with the annular flange 8), and the anti-slip threads 11 are uniformly distributed along the outer peripheral wall of the annular flange 8. When connecting piece inside lining 1 wears to overlap in connecting tube 3, the anti-skidding line 11 of 8 periphery walls of annular flange contradicts with connecting tube 3's inside wall, and anti-skidding line 11 has increased the frictional force between annular flange 8 and connecting tube 3 for connecting piece inside lining 1 alternates in connecting tube 3 more steadily.
Referring to fig. 1 and 2, in order to facilitate connection and disconnection of the joint pipe lining to and from other pipes, a mounting pipe 12 is fixedly connected to the base 2 (the mounting pipe 12 is integrally formed with the base 2), and an outer side wall of the mounting pipe 12 is twisted with a screw thread. The peripheral wall of the base 2 is in a regular hexagon shape. The adjustable spanner of operating personnel cooperates with base 2 for operating personnel revolves base 2 soon more conveniently, is in the same place base 2 and other pipeline threaded connection.
Referring to fig. 2, when an operator replaces a pipeline, the pipeline is detached from one of the installation pipes 12, and at this time, the operator penetrates the plug 13 into the installation pipe 12, and the diameter of the plug 13 gradually changes from large to small. The plug 13 is inserted into the installation pipe 12, so that the one-way sealing of the installation pipe 12 is realized, and the use performance of the installation pipe 12 in actual work is improved.
Referring to fig. 2, a positioning piece 14 is fixedly connected to one end of the plug 13 having a larger diameter (the positioning piece 14 is integrally formed with the plug 13), and the positioning piece 14 is provided to reduce the difficulty in taking out the plug 13 when the plug is completely slid into the connecting pipe 3. Meanwhile, an operator can install and take the plug 13 out of the installation pipe 12 by pinching the positioning piece 14, so that the convenience of taking the plug 13 by the operator is improved.
The implementation principle of the embodiment is as follows: when two pipelines need to be connected together, an operator takes the connecting piece lining 1, puts the sealing ring 10 into the sealing groove 9, and then penetrates the connecting piece lining 1 into the connecting pipeline 3. At this time, the limit column 6 is abutted against one side of the connector liner 1 under the action of the compression spring 7, so that the connector liner 1 is stably inserted into the connecting pipe 3. Then, the staff takes the pipeline that needs to be connected, screws in the cover in other pipelines from one side screw thread of installation pipe 12, realizes that the pipeline is threaded connection on connecting piece inside lining 1 from the one end of installation pipe 12 for connecting pipeline 3 is connected with other pipelines.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
