Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] First embodiment:

[0019] Please see Figure 1 and Figure 2 ,in, Figure 1 This is a schematic diagram of the overall structure of the first embodiment of this utility model. Figure 2 This is a cross-sectional view of the first embodiment of the present invention.

[0020] This utility model provides a pipe docking device for water supply and drainage, including a first pipe 101, a second pipe 102, a rotating unit and a docking assembly. The docking assembly includes an external threaded ring 103, an internal threaded ring 104, a fixing ring 105, a housing 106, a limiting rod 107, a spring 108, a first ring 109 and a first sealing ring 110. The rotating unit includes a second ring 111 and an annular groove 112. The fixing ring 105 has multiple limiting holes 113. The right end of the limiting rod 107 has a chamfered surface 114.

[0021] In this specific embodiment, when it is necessary to disassemble the first pipe 101 and the second pipe 102, first pull the limiting rod 107 to move it, causing the limiting rod 107 to disengage from the limiting hole 113. Then, the external threaded ring 103 can be rotated to disengage from the internal threaded ring 104, thus separating the first pipe 101 and the second pipe 102. When reinstallation is required, first pull the limiting rod 107, then align the external threaded ring 103 with the internal threaded ring 104, and then release the limiting rod 107. Under the elastic force of the spring 108, the limiting rod 107 aligns with the corresponding limiting hole 113, thereby limiting and fixing the external threaded ring 103. To prevent the external threaded ring 103 from disengaging from the internal threaded ring 104, the device can disassemble and install the first pipe 101 and the second pipe 102. The operation is simple and quick, saving workers' time and improving work efficiency. When the worker rotates the external threaded ring 103, it will cause the second ring 111 to rotate within the annular groove 112. Therefore, when the external threaded ring 103 rotates, it will not cause the second pipe 102 to rotate, avoiding the situation where the second pipe 102 rotates during disassembly and installation, thus affecting other connection points of the pipe. The first sealing ring 110 prevents water from leaking from the connection between the internal threaded ring 104 and the external threaded ring 103, improving the sealing effect of the device.

[0022] The rotating unit is connected to the left side of the second pipe 102, the external threaded ring 103 is connected to the left side of the rotating unit, the internal threaded ring 104 is fixedly connected to the right end of the first pipe 101, the external threaded ring 103 and the internal threaded ring 104 are threadedly adapted, the outer shell 106 is fixedly connected to the upper end of the first pipe 101, the fixing ring 105 is fixedly sleeved on the outside of the external threaded ring 103, one end of the limiting rod 107 passes through the outer shell 106 and is adapted to the corresponding limiting hole 113, the first ring 109 is fixedly sleeved on the outside of the limiting rod 107 and located inside the outer shell 106, and the two ends of the spring 108 are fixedly connected to the inner wall of the outer shell 106 and the first ring 109, respectively. When the first pipe 101 and the second pipe 102 need to be disassembled, first pull the limiting rod 107 to move it, so that the limiting rod 107 disengages from the limiting hole 113. Then, the external threaded ring 103 can be rotated to disengage from the internal threaded ring 104, thus separating the first pipe 101 and the second pipe 102. When reinstallation is required, first pull the limiting rod 107, then align the external threaded ring 103 with the internal threaded ring 104, and then release the limiting rod 107. Under the elastic force of the spring 108, the limiting rod 107 aligns with the corresponding limiting hole 113, thereby limiting and fixing the external threaded ring 103 and preventing it from disengaging from the internal threaded ring 104. Thus, this device can disassemble and install the first pipe 101 and the second pipe 102, and the operation is simple and quick, saving workers' time and improving work efficiency.

[0023] Secondly, the annular groove 112 is fixedly connected to the left end of the second pipe 102, and the second ring 111 is rotatably connected to the annular groove 112, with the left end of the second ring 111 fixedly connected to the external threaded ring 103. When the operator rotates the external threaded ring 103, it will cause the second ring 111 to rotate within the annular groove 112. Therefore, when the external threaded ring 103 rotates, it will not cause the second pipe 102 to rotate, thus avoiding the situation where the second pipe 102 rotates during disassembly and installation, thereby affecting other connection points of the pipe.

[0024] Meanwhile, the first sealing ring 110 is fixedly connected to the right end of the first pipe 101, and the right end of the first sealing ring 110 abuts against the left end of the external threaded ring 103. The first sealing ring 110 prevents water from leaking out from the connection between the internal threaded ring 104 and the external threaded ring 103, thus improving the sealing effect of the device.

[0025] In addition, the right end of the limiting rod 107 has a chamfered surface 114. When reinstalling, it is not necessary to pull the limiting rod 107 first. The chamfered surface 114 is pressed by the sides of the multiple limiting holes 113 when the external threaded ring 103 and the fixing ring 105 rotate, so that the limiting rod 107 is finally positioned in the corresponding limiting hole 113. This reduces the operation process for the operator.

[0026] When using the pipe connection device for water supply and drainage of this utility model, when it is necessary to disassemble the first pipe 101 and the second pipe 102, first pull the limiting rod 107 to move it, so that the limiting rod 107 disengages from the limiting hole 113. Then, the external threaded ring 103 can be rotated to disengage from the internal threaded ring 104, and then the first pipe 101 and the second pipe 102 can be separated. When it is necessary to reinstall, first pull the limiting rod 107, then after the external threaded ring 103 is engaged with the internal threaded ring 104, release the limiting rod 107. Under the elastic force of the spring 108, the limiting rod 107 engages with the corresponding limiting hole 113, thereby limiting and fixing the external threaded ring 103 and preventing it from disengaging from the internal threaded ring 104. Thus, this device can disassemble the first pipe 101 and the second pipe 102. The device is easy and quick to install and operate, saving workers' time and improving work efficiency. When the worker rotates the external threaded ring 103, it will drive the second ring 111 to rotate in the annular groove 112. Therefore, when the external threaded ring 103 rotates, it will not drive the second pipe 102 to rotate, avoiding the situation where the second pipe 102 will rotate during disassembly and installation, thus affecting other connection points of the pipe. The setting of the first sealing ring 110 prevents water from leaking out from the connection between the internal threaded ring 104 and the external threaded ring 103, improving the sealing effect of the device. Moreover, when reinstalling, it is not necessary to pull the limiting rod 107 first. It is only necessary to squeeze the chamfered surface 114 through the sides of the multiple limiting holes 113 when the external threaded ring 103 and the fixing ring 105 rotate, so that the limiting rod 107 is finally located in the corresponding limiting hole 113, thereby reducing the operation process for workers.

[0029] This utility model provides a pipe connection device for water supply and drainage, which also includes a handle 201 and a second sealing ring 202.

[0030] In this specific embodiment, the handle 201 facilitates the movement of the limiting rod 107 by the operator, improving convenience. The side of the second sealing ring 202 contacts and abuts against the inner wall of the internal threaded ring 104. The second sealing ring 202 prevents water from leaking out from the connection gap between the annular groove 112 and the second ring 111.

[0031] The handle 201 is fixedly connected to the limiting rod 107 and located at the left end of the limiting rod 107. The second sealing ring 202 is disposed inside the annular groove 112. The handle 201 facilitates the movement of the limiting rod 107 by the operator, improving convenience. The side of the second sealing ring 202 contacts and abuts against the inner wall of the internal threaded ring 104. The second sealing ring 202 prevents water from leaking out from the connection gap between the annular groove 112 and the second ring 111.
