[0017] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is combined with the drawings and example, and the utility model is further detailed.The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] The utility model provides a kind of mechanical type fast plug-in drainage pipe mechanism for water tank, as shown in Figure 1 The drainage pipe mechanism includes drainage cover 3, drainage plug 1 and water tank flange 5;Water tank flange 5 is fixed in water tank bottom plate, and water tank flange 5 can be fixed on water tank bottom plate by welding mode.

[0019] Drainage cover 3 is tubular structure, and drainage cover flange is fixed in the bottom of drainage cover 3, and drainage cover flange and drainage cover 3 are integrated structure, and drainage cover flange and water tank flange 5 cooperate to fix drainage cover 3 in the bottom of water tank, and drainage cover 3 is communicated with water tank outside through water tank flange 5, drainage cover flange and water tank flange 5 are fixed by fastener, and sealing pad 4 is arranged between drainage cover flange and water tank flange 5, and sealing pad 4 can adopt silicon rubber material.Drainage cover 3 pipe wall is evenly arranged with several drainage holes, and drainage cover 3 pipe wall is also provided with slot.

[0020] The drain plug 1 is a cylindrical structure that mates with the axial hole of the tubular structure of the drain sleeve 3. The drain plug 1 can be inserted into the drain sleeve 3 and can also be provided with a handle 2 on the top of the drain plug 1. A fixed shaft 7 that mates with a slot is fixed to the side of the drain plug 1. The drain plug 1 and the fixed shaft 7 are an integrated structure, and the fixed shaft 7 can be limited in the slot and is used to secure the drain plug 1 to the drain sleeve 3. The diameters of the water tank flange 5 and the central hole of the drain sleeve flange are consistent with the diameter of the drain plug 1. After the drain plug 1 is inserted into the drain sleeve 3, the bottom of the drain plug 1 is inserted into the central hole of the water tank flange 5 at the bottom of the water tank, sealing the bottom of the water tank. After the drain plug 1 is removed from the drain sleeve 3, water flows out of the water tank through the drain sleeve 3. The evenly distributed drainage holes in the drain sleeve 3 wall ensure rapid water drainage, and the drainage holes located at the bottom of the drain sleeve 3 wall ensure that all water in the water tank can be discharged without residue.

[0021] The drain sleeve 3, the drain plug 1, the drain sleeve flange and the water tank flange 5 can all be made of stainless steel.

[0022] like Figure 2 As shown, in this embodiment, two slots are symmetrically arranged on the side of the drain sleeve 3, and the top of the slot is connected to the top of the drain sleeve 3; two fixed shafts 7 are symmetrically fixed on the side of the drain plug 1, and the fixed shaft 7 is a columnar structure. When the drain plug 1 is inserted and rotated, the moving trajectory of the fixed shaft 7 is consistent with the shape of the slot, that is, when the drain plug 1 is inserted into the drain sleeve 3 and rotated, the fixed shaft 7 moves along the slot and is finally limited at the end of the slot.

[0023] As an improvement, the slot is composed of three connected structures, the upper section of the slot is arranged along the busbar of the drain sleeve 3, the middle section of the slot is arc-shaped, and the lower section of the slot is arranged circumferentially along the drain sleeve 3; when the drain plug 1 is inserted into the drain sleeve 3, the fixed shaft 7 moves from the top of the drain sleeve 3 along the upper section of the slot to the bottom of the drain sleeve 3; after the drain plug 1 is inserted into place, the fixed shaft 7 reaches the upper end of the arc in the middle section of the slot, and the drain plug 1 is rotated so that the fixed shaft 7 continues to move along the arc in the middle section of the slot until it reaches the upper end of the lower section of the slot, and the drain plug 1 is continued to be rotated until the fixed shaft 7 is limited at the end of the lower section of the slot to prevent the drain plug 1 from detaching from the drain sleeve 3. During the process of inserting the drain plug 1 into the drain sleeve 3 and rotating, the moving trajectory of the fixed shaft 7 is consistent with the shape of the slot; when drainage is required, the drain plug 1 is rotated in the opposite direction of the rotation direction during insertion, so that after the fixed shaft 7 reaches the upper end of the arc in the middle section of the slot, the drain plug 1 is pulled out vertically.

[0024] An annular sealing groove may also be provided on the inner periphery of the middle hole of the drain sleeve flange, and a sealing ring 6 is provided in the annular sealing groove. After the drain plug 1 is inserted into the drain sleeve 3, the sealing ring 6 abuts against the drain plug 1. The sealing ring 6 may be made of rubber material.
