Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, specifically a double-layer drainage floor drain pipe connection device. Background Technology

[0002] A double-layer drainage floor drain refers to a floor drain with two drainage pipes underneath, one for sewage and the other for rainwater. In the design of a double-layer drainage floor drain, the sewage pipe and the rainwater pipe do not interfere with each other and are diverted separately, avoiding the mixing of sewage and rainwater. This design helps to keep the indoor air fresh and effectively prevents the generation of floor drain odors. Specifically, a double-layer filter floor drain also has two layers of filter screens, which can effectively intercept hair, paper scraps and other debris to prevent the drain pipe from getting blocked. The pipe connection device is used to connect the drainage pipes.

[0003] Existing patent CN212839934U discloses a water supply and drainage pipe connection device, including a water supply pipe, a drainage pipe, and a sealing element. A first mounting component and a second mounting component are fixedly installed at the edges of the water supply pipe and drainage pipe, respectively. Both the first and second mounting components have installation channels, and a screw passes through these channels. This water supply and drainage pipe connection device achieves a fixed connection between the water supply pipe and the drainage pipe by using a water supply pipe, a first mounting component, a drainage pipe, a second mounting component, and a sealing element, and by using a screw and nut to fix the first mounting component, the second mounting component, and the sealing element. Sealing nails are used to engage in positioning grooves. The arrangement of multiple sets of sealing nails and positioning grooves increases the contact area between the sealing element and the water supply and drainage pipes, thus improving the sealing performance between the water supply and drainage pipes. This water supply and drainage pipe connection device is easy to install, has high sealing performance, and can effectively prevent water leakage at the connection between the water supply and drainage pipes.

[0004] The existing technology has the following problems:

[0005] 1. The existing double-layer drainage floor drain pipe connection device only connects and fixes the pipes by setting bolts. This makes it easy for the connection between the pipes to become unstable as the usage time increases, which leads to loosening of the pipe connection, increases maintenance costs, and fails to meet the usage requirements.

[0006] 2. The existing double-layer drainage floor drain pipe connection device has a less than ideal sealing performance, which may lead to water leakage at the connection between the device and the pipe during long-term use, reducing the practicality of the device and making it inconvenient to promote. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a double-layer drainage floor drain pipe connection device, which solves the problem that with the increase of usage time, the connection between pipes is prone to loosening, resulting in loosening at the pipe connection and less than ideal sealing performance. This also leads to the problem of water leakage at the connection between the device and the pipe during long-term use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a double-layer drainage floor drain pipe connection device, including a mounting frame, a first connection hole on one side of the mounting frame, a connecting rod inside the first connection hole, a positive thread on one side of the outer surface of the connecting rod, a positive locking nut on the outer surface of the positive thread on the connecting rod, a reverse thread on the other side of the outer surface of the connecting rod, a reverse locking nut on the outer surface of the reverse thread on the connecting rod, a pipe body on one side of the mounting frame near the first connection hole, a second connection hole on one side of the pipe body, and a sealing mechanism inside the mounting frame.

[0009] As a preferred technical solution of this utility model, the size of the mounting bracket is adapted to the size of the pipe body, and there are four sets of the first connecting holes. The four sets of the first connecting holes are arranged in a circular array on the mounting bracket, and the positions of the first connecting holes and the positions of the second connecting holes are set to correspond to each other.

[0010] As a preferred embodiment of this utility model, the forward thread and the reverse thread are integrally formed with the connecting rod, and the dimensions of the forward locking nut and the reverse locking nut are respectively adapted to the dimensions of the forward thread and the reverse thread.

[0011] As a preferred embodiment of this utility model, the sealing mechanism is fixedly installed on the mounting bracket, and the size of the sealing mechanism is adapted to the size of the pipe body.

[0012] As a preferred embodiment of the present invention, the sealing mechanism includes a sealing element, a sealing gasket is provided on one side of the sealing element, a first sealing ring is provided on the side of the sealing gasket of the sealing element, and a second sealing ring is provided on the side of the first sealing ring of the sealing element.

[0013] As a preferred embodiment of this utility model, the size of the sealing gasket is adapted to the size of the sealing element, and there are two sets of sealing gaskets, which are arranged corresponding to each other at the midpoint of the size of the sealing element.

[0014] As a preferred technical solution of this utility model, the first sealing ring and the second sealing ring are both installed on the sealing element by adhesive connection, the positions of the first sealing ring and the second sealing ring are respectively arranged to correspond to each other, and the first sealing ring and the second sealing ring are specifically made of rubber material.

[0015] Compared with the prior art, this utility model provides a double-layer drainage floor drain pipe connection device, which has the following beneficial effects:

[0016] 1. This double-layer drainage floor drain pipe connection device, by setting up an installation bracket, a first connection hole, a connecting rod, a forward thread, a forward locking nut, a reverse thread, a reverse locking nut, and a second connection hole, allows for connection by first inserting two sets of pipe bodies into the left and right sides of the installation bracket, aligning the second connection holes on the two sets of pipe bodies with the first connection holes on the installation bracket, and then fitting the first connection hole and the second connection hole together with the connecting rod. Simultaneously, the forward locking nut and the reverse locking nut are threaded into the forward and reverse threads on the connecting rod, respectively, forming an interlocking structure. This further strengthens the firmness and stability of the connection between the installation bracket and the pipe body, making the connection less prone to detachment or loosening. This design avoids the problem of unstable pipe connections over time, reduces maintenance costs, and meets usage requirements.

[0017] 2. This double-layer drainage floor drain pipe connection device, by setting sealing elements, sealing gaskets, a first sealing ring and a second sealing ring, when one end of the pipe body is inserted into the mounting bracket, firstly, the end of the pipe body abuts against the sealing gasket, improving the sealing effect of the connection between the mounting bracket and the pipe body. Then, through the mutual cooperation of the first sealing ring and the second sealing ring, the sealing effect at the connection between the device and the pipe is further strengthened. This design, through the setting of multiple sealing structures, improves the sealing performance of the device, avoids the problem of water leakage at the connection between the device and the pipe during long-term use, improves the practicality of the device, and facilitates its promotion.
