Problems solved by technology
[0002] Existing connection methods of pipe fittings mainly include ferrule type connection, compression type connection, etc. The connection methods of these pipe fittings have the following disadvantages: the installation is time-consuming and labor-intensive, special special tools are required for installation, and it is difficult to replace the pipe fittings after the pipeline leaks, maintenance high cost
[0004] However, in the above-mentioned technical solution, the internal tooth washer is fixed in the groove in the shape of a door. The internal tooth washer is not only difficult to install, but also easy to damage the internal tooth washer during the insertion and removal of the pipe, and it is inconvenient to replace.
At present, there is a method of fixing the internal tooth washer by thread connection, that is, external threads are provided outside the internal tooth washer, and internal threads matching the external threads on the internal tooth washer are provided in the pipe fitting body. This method of fixing the internal tooth washer It is still not convenient for the installation and replacement of the inner tooth washer, and it is not convenient for the processing and manufacturing of pipe fittings

Embodiment Construction
[0028] Embodiments of the present invention are described in detail below:
[0029] see Figure 1 to Figure 8 , an in-line quick-connect pipe fitting, including a pipe fitting body 1, the pipe fitting body 1 is an elbow pipe fitting, and the present invention is not limited to elbow pipe fittings, and can also be applied to straight-through, three-way, and four-way pipe fittings. The end of the main body 1 is sequentially provided with a sealing ring 2 and an internal tooth washer 4 with teeth inclined and diverging toward the sealing ring 2 along its opening direction, and a compression ring 6 is connected to the internal tooth washer 4. The inner wall of the pipe fitting body 1 is provided with a groove 104 for installing the compression ring 6 .
[0030] Such as Figure 6 As shown, the pressing ring 6 is in the shape of an open ring. The purpose of designing the opening 603 is to ensure that the compression ring 6 can be smoothly snapped into the groove 104 of the pipe b...

The invention discloses a direct insertion quick connecting pipe fitting which comprises a pipe fitting body. An internal tooth washer is arranged inside the pipe fitting body, a pressing ring is further arranged inside the pipe fitting body, a groove which is used for mounting the pressing ring is formed in the inner side wall of the pipe fitting body, and one end of the pressing ring abuts against the internal tooth washer. The pressing ring is additionally arranged inside the pipe fitting body, so that the internal tooth washer is extruded to be fixed through the pressing ring, the fact that a groove which is used for fixing the internal tooth washer is formed in the pipe fitting body is avoided, and therefore the fact that an opening is formed in the internal tooth washer is of no need. The direct insertion quick connecting pipe fitting is convenient for the internal tooth washer to mount and replace and simple in structure.
Description
technical field [0001] The invention relates to the technical field of pipe fitting installation, in particular to an in-line quick-connect pipe fitting. Background technique [0002] Existing connection methods of pipe fittings mainly include ferrule type connection, compression type connection, etc. The connection methods of these pipe fittings have the following disadvantages: the installation is time-consuming and labor-intensive, special special tools are required for installation, and it is difficult to replace the pipe fittings after the pipeline leaks, maintenance high cost. [0003] In view of the above defects, the Chinese patent specification discloses an in-line quick-connect pipe fitting and a pipe taking sleeve, which are provided with sealing rings along the opening direction in the end of the pipe fitting body, and internal teeth with inclined and divergent teeth facing the sealing ring. The washer is provided with an annular protrusion on the inner wall of ...
