The locking frame 24 will reset under the elastic action of the third spring 23 to squeeze the steel ball 21, so that the steel ball 21 is clamped in the clamping groove 12 provided on the outer side of the male head 2 for positioning. Then, the second plug 17 provided inside the female head 1 will contact and squeeze the first plug 10 provided inside the male head 2, so that the female head 1 and the male head 2 are in a flowing state. Furthermore, the connection device of the drainage pipe has the effect of quick docking, and the operation is simple, so as to improve the installation efficiency between the drainage pipes.

[0028] In the present utility model, preferably, one end of the female head 1 and the male head 2 are respectively provided with a first pipeline connector 3 and a second pipeline connector 4, and threaded grooves 5 are formed inside both the first pipeline connector 3 and the second pipeline connector 4.

Both the second movable frame 16 and the fifth rubber ring 19 are slidably connected inside the female head 1, and a fourth rubber ring 18 is snap - connected to the outside of the second plug 17.

[0033] In the present utility model, preferably, a fifth rubber ring 19 is snap - connected to one end inside the female head 1.

[0034] In the present utility model, preferably, a number of ball grooves 20 and steel balls 21 are circularly arranged, and an anti - slip groove 26 is provided on the outside of the locking frame 24.

[0035] Working principle and usage process of the present utility model: When in use, the female head 1 and the male head 2 are the core parts of the device. Both are respectively equipped with a first valve and a second valve, as well as a clamping groove 12 for clamping. When connecting, the user inserts the front end of the male head 2 into the clamping groove 12 of the female head 1. This is a preliminary docking that can be quickly completed by the naked eye. To achieve a quick and stable connection, a ball groove 20 is designed inside the female head 1, and a steel ball 21 is rotatably connected therein. This design allows the steel ball 21 to roll freely inside the female head 1 until it encounters the clamping groove 12 on the outer side of the male head 2. At this time, the limit platform 22 and the third spring 23 come into play, and the steel ball 21 is compressed into the clamping groove 12 through the pressing block 25 and the locking frame 24 to complete precise positioning. When the steel ball 21 is positioned, the first valve and the second valve inside the female head 1 and the male head 2 will come into contact and squeeze each other, thus ensuring the flow state between the two, enabling the pipeline to start draining water. To enhance the connection tightness and safety, one end of the male head 2 and the female head 1 are respectively equipped with a first pipeline connector 3 and a second pipeline connector 4. Thread grooves 5 are provided inside both of them. When the connectors are rotationally engaged, the thread grooves will provide additional grip to ensure that the connection will not accidentally loosen. In addition, at the contact part of the female head 1 and the male head 2, multiple rubber rings, namely the first rubber ring 7, the second rubber ring 11, the third rubber ring 14, and the fifth rubber ring 19, are provided. Their presence increases the connection tightness and prevents water leakage. The entire connection process is simple to operate. The user only needs to toggle the locking frame 24, and after the steel ball 21 is compressed, it can be easily inserted into the inside of the female head 1. Further, by rotating the first pipeline connector 3 and the second pipeline connector 4, the final connection is completed. This design greatly improves the installation efficiency of the drainage pipeline and also ensures the quality and reliability of the connection.
