[0007] Preferably, the disassembly and assembly assembly includes a first annular block fixedly mounted on the inner wall of the first tube, a third annular block fixedly mounted on the inner wall of the first tube, the third annular block being located between the first annular block and the siphon drain pipe body, a telescopic rod fixedly mounted on a side wall of the third annular block close to the first annular block, a second annular block fixedly mounted on the telescopic end of the telescopic rod, a first groove is formed on a side wall of the first annular block away from the third annular block, a second groove is formed on a side wall of the first annular block close to the third annular block, and a clamping block is fixedly mounted on the outer side wall of the second tube.

[0008] Preferably, the first groove and the second groove are of the same size, the first groove is a through groove, and the clamping block is matched with the first groove and the second groove.

[0009] Preferably, the outer diameter of the second tube is equal to the inner diameters of the first annular block, the second annular block and the third annular block.

[0010] Preferably, the second annular block is slidably connected to the inner wall of the first tube.

[0011] Preferably, a pointer is fixedly mounted on the outer side wall of the second tube, and a positioning mark is fixedly mounted on a side wall of the first annular block away from the third annular block, and the position of the positioning mark corresponds to the position of the second groove.

[0012] Beneficial effects of the utility model:

[0013] By setting up a disassembly and assembly component, the installation and disassembly between the rainwater head and the siphon drain pipe body can be completed through the cooperation between the clamping block and the first groove and the second groove.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A siphon drainage device includes a siphon drainage pipe body 1, a first pipe 2 is arranged on the siphon drainage pipe body 1, a siphon rainwater head 4 is arranged on the outside of the first pipe 2, a second pipe 3 is arranged at the bottom of the siphon rainwater head 4, and a disassembly assembly is arranged between the first pipe 2 and the second pipe 3.

[0020] The disassembly and assembly assembly includes a first annular block 7 fixedly mounted on the inner wall of the first tube 2, a third annular block 14 fixedly mounted on the inner wall of the first tube 2, the third annular block 14 is located between the first annular block 7 and the siphon drain pipe body 1, a telescopic rod 12 is fixedly mounted on one side wall of the third annular block 14 close to the first annular block 7, a second annular block 11 is fixedly mounted on the telescopic end of the telescopic rod 12, a first groove 8 is provided on one side wall of the first annular block 7 away from the third annular block 14, a second groove 10 is provided on one side wall of the first annular block 7 close to the third annular block 14, and the third annular block 12 is fixedly mounted on the telescopic end of the telescopic rod 12. A clamping block 9 is fixedly installed on the outer wall of the second tube 3, the first groove 8 and the second groove 10 are of the same size, the first groove 8 is a through groove, the clamping block 9 and the first groove 8 and the second groove 10 are all adapted to each other, the outer diameter of the second tube 3 is equal to the inner diameters of the first annular block 7, the second annular block 11 and the third annular block 14, the second annular block 11 is slidably connected to the inner wall of the first tube 2, a pointer 5 is fixedly installed on the outer wall of the second tube, a positioning mark 6 is fixedly installed on the side wall of the first annular block 7 away from the third annular block 14, and the position of the positioning mark 6 corresponds to the position of the second groove 10.

[0021] When the utility model is used, the block 9 on the second tube 3 is made to correspond to the first groove 8. Since the block 9 is adapted to the first groove 8, the block 9 can pass through the first groove 8. When the block 9 passes through the first groove 8, the block 9 contacts the second annular block 11, so that the second annular block 11 slides in the direction close to the third annular block 14, the telescopic rod 12 retracts, the spring 13 is compressed, and after the block 9 passes through the first groove 8, the second tube 3 is rotated, and the rotation of the second tube 3 drives the block 9 to rotate. When the pointer 5 on the second tube 3 is aligned with the positioning mark 6, the block 9 rotates to the position corresponding to the second groove 10 and the second tube 3 is slowly released. The elastic force generated by the compression of the spring 13 can make the block 9 enter the second groove 10, and the connection between the first tube 2 and the second tube 3 is completed;

[0022] When it is necessary to complete the disassembly between the first tube 2 and the second tube 3, the second tube 3 is moved downward so that the block 9 is away from the second groove 10, and then the second tube 3 is rotated to align the block 9 with the first groove 8. The block 9 on the second tube 3 cooperates with the first groove 8 to pass through the first annular block 7. The operation is simple and convenient.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
