[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 5 As shown, this utility model provides a quick-connect fitting for drainage pipes in building construction, including a connector 1. An extension pipe 3 is fixedly installed at the top of the connector 1. A connector 2 is provided in the inner cavity of the extension pipe 3. A storage pipe 4 is slidably connected to the inner cavities of both the connector 2 and the connector 1. A sealing ring 5 and an extension ring 6 are fixedly installed on the outer wall of the storage pipe 4. A limit ring 7 is fixedly installed in the inner cavities of both the connector 1 and the connector 2. A sealing ring 8 is inserted into the end of the extension ring 6 near the limit ring 7.

[0016] By storing adhesive in the space formed between the sealing ring 5, the extension ring 6 and the outer wall of the storage tube 4, the storage tube 4 can be removed in advance when connecting the drain pipe. During the removal of the storage tube 4, since there is a gap between the extension ring 6 and the connector 2, the adhesive can be applied to the side walls of the connector 2 and the connector 1. The construction personnel no longer need to carry adhesive, thus achieving fast and uniform adhesive application.

[0017] Among them, sealing ring 5 contacts joint 1 and joint 2, and there is a three-millimeter gap between extension ring 6 and joint 1 and joint 2.

[0018] refer to Figure 3 The sealing ring 5 directly contacts the connector 1 and connector 2 to seal the space above the adhesive. The extension ring 6 is designed to have a gap between it and connector 2 and connector 1, allowing the adhesive to flow out through this gap and be applied to connector 1 and connector 2.

[0019] Among them, the sealing ring 28 is in close contact with the limiting ring 17, and the top of the limiting ring 17 is a bevel.

[0020] The adhesive is sealed by the tight contact between the limiting ring 7 and the sealing ring 8, which isolates the adhesive from the space and water and prevents it from solidifying. The top surface of the limiting ring 7 is set as a slope to prevent sewage from remaining on the limiting ring 7 during drainage.

[0021] Among them, an extension rod 9 is fixedly installed at the end of the storage tube 4 away from the extension tube 3. A fixing tube 11 and a spring 14 are fixedly installed at both ends of the extension rod 9. A locking pin 12 is slidably connected to the inner cavity of the fixing tube 11. A support ring 13 is fixedly installed on the surface of the locking pin 12.

[0022] By opening round holes on connector 1 and connector 2, when the product is not in use, the elasticity of spring 14 enables the locking pin 12 to be inserted into the round hole, thereby locking the extension rod 9 and positioning the storage tube 4 to prevent it from falling off.

[0023] Among them, a pull ring 10 is fixedly installed at the end of the extension rod 9 away from the storage tube 4. The pull ring 10 is circular. An extension piece 15 is fixedly installed at the rear end of the locking pin 12. The spring 14 is fixedly connected to the locking pin 12 and is located inside the fixing tube 11.

[0024] The pull ring 10 facilitates the extension rod 9 to be pulled out, and the extension piece 15 allows for easy movement of the locking pin 12.

[0025] Among them, the top end of the extension tube 3 is fixedly installed with a limit ring 16, the bottom end of the connector 2 is fixedly installed with a positioning ring 17, and a sealing ring 18 is placed in the middle of the positioning ring 17.

[0026] By setting the sealing ring 3 18, a seal can be achieved between the connector 2 and the extension pipe 3. Furthermore, by setting the connector 2 to be able to slide up and down inside the extension pipe 3, the total length of the connector 1 and the connector 2 can be changed by pulling the connector 2, thus enabling the connection of gaps between different drain pipes.

[0027] Working principle and usage process of this utility model: First, wipe both ends of the drain pipe. Then, use the extension piece 15 to move the locking pin 12 so that the locking pin 12 leaves the round hole. Use the pull ring 10 to pull out the extension rod 9 and the storage tube 4. During the pulling process, since there are gaps between the extension ring 6 and the connector 1 and connector 2, the glue will flow out from the gaps and then be applied to the connector 1 and connector 2. With connector 2 on top and connector 1 on the bottom, place this product between two drain pipes. Then, put connector 1 on the drain pipe downstream in the drainage direction, and pull connector 2 inside the extension pipe 3 so that connector 2 is put on the other drain pipe.
