DETAILED DESCRIPTION
[0020] like Figures 1 to 3 As shown, the present application is a metal pipe quick-plug connector, including a mounting cylinder 101 and a mounting cylinder 2 103 located above the mounting cylinder 101, and a threaded pipe 102 is connected below the mounting cylinder 101;
[0021] The second installation cylinder 103 is provided with a moving cylinder 104 penetrating the upper end thereof, and a limiting assembly for limiting the metal pipe is provided inside the moving cylinder 104, and the limiting assembly includes a limiting block 109 and a spring 110. The left and right sides of the inner wall of the moving cylinder 104 are provided with grooves 108, and the limiting blocks 109 are provided with two pieces and are respectively inserted into the two grooves 108, and the springs 110 are provided with two pieces and are respectively connected between the two limiting blocks 109 and the bottom of the corresponding groove 108;
[0022] When the metal pipe quick-plug connector is used, the threaded pipe 102 is screwed into one of the metal pipes to be connected, and the other metal pipe to be connected is inserted into the moving cylinder 104. Since there are two limit blocks 109 and they are respectively inserted into the two grooves 108, and there are two springs 110 and they are respectively connected between the two limit blocks 109 and the bottom of the corresponding grooves 108, the metal pipe can push the limit blocks 109 outward into the grooves 108. At this time, the spring 110 is compressed, and the elastic force of the spring 110 can limit the metal pipe to a certain extent.
[0023] The installation cylinder 101 and the installation cylinder 2 103 are detachably connected. The installation cylinder 2 103 is provided with a retaining spring 115 for limiting the metal pipe. The installation cylinder 101 is connected with a support ring 114. The support ring 114 and the retaining spring 115 are detachably connected. The left and right sides of the inner wall of the installation cylinder 2 103 are provided with sliding grooves 111. Two sliding blocks 112 are provided and are respectively connected to the left and right sides of the moving cylinder 104 and are slidably connected in the adjacent sliding grooves 111.
[0024] An oblique groove 117 is formed on the inner end of the support ring 114, and the retaining ring 115 is located in the oblique groove 117. The mounting ring 116 is connected to the upper end of the retaining ring 115, and the mounting ring 116 is connected to the support ring 114 through bolts. The pressure ring 113 is connected to the lower end of the moving cylinder 104, and the lower end of the pressure ring 113 is in contact with the upper surface of the retaining ring 115.
[0025] When the user inserts the metal pipe into the moving cylinder 104, the moving cylinder 104 is moved downward. Since the left and right sides of the inner wall of the second installation cylinder 103 are provided with slide grooves 111, the sliding block 112 is provided with two pieces and is respectively connected to the left and right sides of the moving cylinder 104 and is slidably connected in the adjacent slide grooves 111, so when the moving cylinder 104 moves downward, the sliding block 112 can move up and down along the slide groove 111 to prevent the moving cylinder 104 from separating from the second installation cylinder 103, and at the same time, the stability of the movement of the moving cylinder 104 is improved to a certain extent. Since the retaining spring 115 is located in the inclined groove 117, the pressure ring 113 is connected to the lower end of the moving cylinder 104, and the lower end of the pressure ring 113 is in contact with the upper surface of the retaining spring 115, the pressure ring 113 can push the retaining spring 115 downward, and the retaining spring 115 can move downward and deform. At this time, the metal pipe can continue to move downward through the retaining spring 115, which is convenient for subsequent plugging;
[0026] A sealing ring 107 and a sealing ring 106 are respectively arranged inside the installation tube 101 and inside the threaded tube 102. The sealing ring 107 is attached to the inner wall of the installation tube 101 and is located below the support ring 114. A connecting ring 105 is connected inside the threaded tube 102, and the sealing ring 106 is attached above the connecting ring 105.
[0027] When the metal pipe passes through the retaining ring 115, since the sealing ring 107 fits the inner wall of the installation tube 101 and is located below the support ring 114, the metal pipe can pass through the sealing ring 107. At this time, the sealing ring 107 is compressed, and the sealing ring 107 can improve the sealing between the installation tube 101 and the metal pipe. When the sealing ring 107 is squeezed, it can also limit the metal pipe to a certain extent. Since the threaded pipe 102 is internally connected with the connecting ring 105, the sealing ring 106 fits above the connecting ring 105. After the metal pipe passes through the sealing ring 107, it continues to move downward and can contact and squeeze the sealing ring 106. At this time, the sealing ring 106 can improve the sealing between the metal pipe and the connecting ring 105, thereby effectively improving the sealing between the metal pipe and the threaded pipe 102, thereby effectively improving the sealing at the metal pipe quick-connect plug, and effectively avoiding leakage;
[0028] like Figure 1 and Figure 2 As shown, after the user plugs the metal pipe into the extrusion sealing ring 106, the moving cylinder 104 moves upward, and the pressure ring 113 can move upward with the moving cylinder 104, and the retaining spring 115 can reset upward to limit the metal pipe, thereby completing the plug-in limit of the metal pipeline and completing the connection between the two metal pipes, with good sealing performance;
[0029] The installation tube 1 101 and the installation tube 2 103 are connected by bolts;
[0030] Since the mounting cylinder 101 and the mounting cylinder 2 103 are connected by bolts, the mounting ring 116 is connected to the upper end of the retaining ring 115, and the mounting ring 116 is connected to the support ring 114 by bolts, the bolts between the mounting cylinder 101 and the mounting cylinder 2 103 are removed, and the limit between the mounting cylinder 101 and the mounting cylinder 2 103 can be released, and the mounting cylinder 2 103 is moved upward to be separated from the mounting cylinder 101, and the mounting ring 116 inside the mounting cylinder 101 can be exposed, and the mounting ring 116 and the support ring 114 are connected. By removing the bolts, the user can remove the mounting ring 116 and the retaining spring 115 for replacement, place the new mounting ring 116 and retaining spring 115 on the support ring 114, connect the new mounting ring 116 to the support ring 114 by bolts, and then connect the mounting tube 101 and the mounting tube 2 103 to each other by bolts, thereby completing the replacement of the retaining spring 115. Replacing the retaining spring 115 can effectively prevent the elasticity of the retaining spring 115 from weakening and affecting the stability of the metal pipe connection, thereby further ensuring the sealing of the metal pipe quick-connect plug.
