DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a drain plug linkage device;

[0024] It includes a connecting cylinder 1, a connecting tube 2 and an assembling cylinder 5. The inner wall of the assembling cylinder 5 is provided with four groups of limiting grooves 7. A plug column 12 is movably arranged inside the assembling cylinder 5. The bottom end of the plug column 12 is connected to a telescopic rod 10. The bottom end of the plug column 12 is connected to a spring 11, and the spring 11 is located outside the telescopic rod 10. The bottom end of the plug column 12 is connected to four groups of connecting plates 14. A protrusion 15 is connected to one side of the connecting plate 14, and the protrusion 15 is engaged with the limiting groove 7. A sliding ring 16 is movably arranged inside the assembling cylinder 5.

[0025] The limiting grooves 7 are symmetrically arranged in four groups on the inner wall of the assembly tube 5. After the limiting grooves 7 are connected with the protrusions 15, the limiting grooves 7 can position the protrusions 15 so that the plug 12 is positioned and installed inside the assembly tube 5, so that the spring 11 is in a compressed and deformed state. The bottom end of the protrusion 15 adopts an arc design, and the connecting plate 14 plays a connecting role. The connecting plate 14 provides a suitable installation position for the protrusion 15. After the extrusion force is applied to the plug 12, the plug 12 drives the protrusion 15 to slide downward inside the limiting grooves 7. After the arc surface at the bottom end of the protrusion 15 is squeezed and contacted with the limiting grooves 7, the connecting plate 14 is slightly deformed, so that the protrusion 15 slides down to the inside of the sliding ring 16. The outer side of the sliding ring 16 is a smooth surface in contact with the inner wall of the assembly cylinder 5, and the inner wall of the sliding ring 16 is a rough surface. The protrusion 15 is squeezed and contacted with the inner wall of the sliding ring 16. The elastic action of the spring 11 can drive the sliding ring 16 to slide upward inside the assembly cylinder 5. The engaging block 17 arranged on the outer side of the sliding ring 16 slides from the bottom inner wall of the engaging groove 8 to the top inner wall of the engaging groove 8. At this time, the sliding ring 16 moves upward to cover the limiting groove 7, so that the plug 12 can protrude from the assembly cylinder 5. The protruding plug 12 can be positioned by the telescopic rod 10 and the spring 11. The sliding ring 16 can slide down to the original position by gravity and the impact force of the flow.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a drain plug linkage device;

[0027] The bottom end of the connecting tube 1 is combined and connected with a connecting tube 2, and the connecting tube 2 is threadedly connected to the connecting tube 1, four groups of guide grooves 3 are opened inside the connecting tube 1, and a retaining ring groove 4 is opened on the inner wall of the connecting tube 1, and the retaining ring groove 4 is connected with the inside of the guide groove 3, and four groups of retaining blocks 6 are arranged on the outer side of the assembling tube 5, and the retaining blocks 6 are movably combined and connected with the guide groove 3, and the retaining blocks 6 are movably combined and connected with the retaining ring groove 4.

[0028] The connecting cylinder 1 and the connecting pipe 2 are one of the main components of the drain plug linkage device. The connecting pipe 2 and the connecting cylinder 1 are threadedly connected to facilitate the assembly of the connecting pipe 2 and the connecting cylinder 1. The locking block 6 arranged on the outside of the assembly cylinder 5 is movably combined and connected with the guide groove 3 and the locking ring groove 4. The guide groove 3 is used to guide the locking block 6 up and down. After the locking block 6 slides into the locking ring groove 4, the assembly cylinder 5 is rotated by a certain angle, so that the assembly cylinder 5 and the connecting cylinder 1 can be assembled, which is convenient for the later disassembly and replacement of the assembly cylinder 5.

[0029] like Figure 4 and Figure 5 As shown, a drain plug linkage device;

[0030] The inner wall of the assembly tube 5 is connected to a support frame 9, and the top of the support frame 9 is connected to the bottom end of the telescopic rod 10 and the spring 11, a plurality of sealing rings 13 are arranged on the outer side of the plug 12, and the sealing rings 13 are made of rubber material, and the sealing rings 13 are in contact with the inner wall of the assembly tube 5, and four groups of engaging blocks 17 are arranged on the outer side of the sliding ring 16, and the engaging blocks 17 are movably connected to the engaging groove 8.

[0031] The support frame 9 is installed on the inner wall of the assembly tube 5 by connection. The support frame 9 is a cross circular plate shape. The support frame 9 can support the bottom end of the spring 11 and the telescopic rod 10. The sealing ring 13 on the outside of the plug 12 is in contact with the inner wall of the assembly tube 5. The sealing ring 13 and the plug 12 can seal the inside of the assembly tube 5 to achieve a sealing effect on the drain port of the container. The joint block 17 is movably assembled in the joint groove 8. The joint groove 8 can make the sliding ring 16 movably connected and installed in the inside of the assembly tube 5.

[0032] Before use, the connecting tube 1 is sealed and connected to the bottom end of the container, and the guide groove 3 is used to guide the positioning block 6 to move up and down. After the positioning block 6 slides into the inside of the positioning ring groove 4, the assembly tube 5 is rotated by a certain angle, so that the assembly tube 5 and the connecting tube 1 can be assembled, which is convenient for the later disassembly and replacement of the assembly tube 5;

[0033] After the limiting groove 7 is connected with the protrusion 15, the plug 12 is positioned and installed inside the assembly tube 5. At this time, the spring 11 is in a compressed and deformed state. After the extrusion force is applied to the plug 12, the plug 12 drives the protrusion 15 to slide downward inside the limiting groove 7. After the arc surface at the bottom end of the protrusion 15 is squeezed and contacted with the limiting groove 7, the connecting plate 14 is slightly deformed, causing the protrusion 15 to slide down to the inside of the sliding ring 16.
