Description

Technical Field

[0001] The utility model relates to the technical field of bathroom drain pipes, in particular to a high-efficiency sealing connection device for bathroom drain pipes. Background Technique

[0002] A bathroom drain pipe refers to a water pipe system used to discharge waste water in bathroom facilities, including drain pipes for wash basins, bathtubs, shower rooms, toilets, etc. When pipes are connected, connection devices are often required;

[0003] After retrieval, a patent with the authorized announcement number CN221278736U proposes a connection structure for drain pipes. The following problems exist in this technical solution:

[0004] Currently, when a drain pipe drains water, due to the inconvenience of playing a check valve role and the inability to prevent reverse blockage, after long-term drainage, not only is it easy for mosquitoes to crawl back in the pipe, but also the phenomenon of odor return occurs, thereby reducing the applicability of use;

[0005] In view of the above problems, the utility model document proposes a high-efficiency sealing connection device for bathroom drain pipes. Content of the Utility Model

[0006] The utility model provides a high-efficiency sealing connection device for bathroom drain pipes, which solves the disadvantages in the prior art that due to the inconvenience of playing a check valve role and the inability to prevent reverse blockage, after long-term drainage, not only is it easy for mosquitoes to crawl back in the pipe, but also the phenomenon of odor return occurs, thereby reducing the applicability of use.

[0007] The utility model provides the following technical solutions:

[0008] A high-efficiency sealing connection device for bathroom drain pipes, comprising:

[0009] Two drain pipes, a connecting pipe is arranged between the two drain pipes, and one end of each drain pipe is communicated with a connecting block corresponding to the connecting pipe;

[0010] Both ends of the connecting pipe are communicated with threaded heads, a threaded groove for threaded connection of the threaded heads is formed on one side of each connecting block, and a sealing gasket closely attached to one side of the inner wall of the threaded groove is arranged on one side of each threaded head;

[0011] A check valve mechanism, which is arranged in the connecting pipe to prevent the phenomenon of water volume backflow and odor return in the drain pipe;

[0012] A support mechanism, which is arranged outside the drain pipe to support and fix the drain pipe.

[0013] In a possible design, the check mechanism includes a check pipe, a fixing plate, a check cover, and a sealing ring. The check pipe is fixedly installed on the inner wall of the connecting pipe. A sealing ring is provided on the outer wall of the check pipe, and the outer wall of the sealing ring is in close fit with the inner wall of the connecting pipe. The fixing plate is fixedly arranged on one side of the check pipe. The check cover is rotatably connected to one side of the fixing plate through a rotating shaft and is used to cover the check pipe.

[0014] In a possible design, the support mechanism includes two groups of arc-shaped blocks, four rubber pads, two support rods, and two fixing blocks. The two groups of arc-shaped blocks are respectively arranged outside the two drain pipes. Each group of arc-shaped blocks consists of two. Each rubber pad is fixedly arranged on the inner wall of each arc-shaped block. A connecting plate is fixedly arranged at each end of each arc-shaped block. The four connecting plates are divided into two groups, and each group of connecting plates is fixedly connected through a fastener. Each fastener respectively includes a bolt and a nut.

[0015] In a possible design, one end of each support rod is fixed to the outer wall of one of the arc-shaped blocks, and the other end of the support rod is fixed to one side of the fixing block. Three fixing holes are provided on one side of each fixing block.

[0016] In a possible design, a maintenance pipe is communicated with the outer wall of the connecting pipe. The outer wall of the maintenance pipe is provided with an external thread, and a sealing cover threadedly connected to the external thread is arranged outside the maintenance pipe. A plurality of anti-slip protrusions are fixedly arranged on the outer wall of the sealing cover.

[0017] In a possible design, both the sealing ring and the two sealing gaskets are made of ethylene propylene diene monomer (EPDM) rubber.

[0018] In the present application, when in use, first the two drain pipes are threadedly connected to the threaded heads at both ends of the connecting pipes through the connecting blocks at their respective ends. The connection method is not only simple and fast, but also achieves initial connection stability through the tight engagement of the threads. When the threaded head is screwed into the thread groove of the connecting block, the sealing gasket on one side of the threaded head will be pressed against the inner wall of the thread groove to form a tight sealing layer. The EPDM rubber material used for the sealing gasket has good elasticity and water resistance, which can ensure long-term and effective sealing effect and prevent water from leaking from the connection. During normal drainage, the water flow will push the check cover to open, allowing the water to flow smoothly through the check pipe to the downstream drain pipe. If water backflow or gas backflow occurs, the check cover will open under reverse pressure. It automatically closes under the action of force and restores the sealing state, effectively preventing water or gas from flowing back into the upstream drain pipe, thereby preventing water backflow and odor regurgitation. The check pipe is fixedly installed in the connecting pipe, and its design allows water to pass in one direction. The sealing ring is also made of EPDM rubber and fits tightly between the check pipe and the connecting pipe to ensure the sealing of the check pipe installation. The check cover is rotatably connected to the fixed plate through a rotating shaft. It is usually in a closed state, covering the outlet of the check pipe to prevent water backflow and odor backflow. Therefore, the drain pipe can play a check role when draining and can achieve the purpose of reverse prevention, avoiding the situation where mosquitoes and insects easily crawl back into the pipe and odor regurgitation after long-term drainage, thereby improving the applicability of use;

[0019] The cam is then screwed down to allow the user to open or close the cam, and the cam is then screwed down to allow the user to open or close the cam when the cam is in use.

[0020] In the present invention, the highly efficient sealed bathroom drainage pipe connection device can effectively prevent water or gas from flowing back into the upstream drainage pipe through the anti-return mechanism, thereby preventing water backflow and anti-odor phenomena;

[0021] In the present utility model, the high-efficiency sealed sanitary drainage pipe connecting device can be firmly installed on a wall or other fixed structures through a support mechanism, thereby ensuring the stability and safety of the drainage pipe, enhancing the firmness during the drainage process of the drainage pipe, and improving the application effect.

[0022] In the present utility model, when the drainage pipe is draining, it is convenient to play an anti-backflow role, and the purpose of reverse prevention can be achieved, avoiding the situation that mosquitoes and insects crawl back and the pipe smells after long-term drainage, thereby improving the applicability of use.
