Detailed Description

As shown in fig. 1-4, a drainer structure includes a drainer body, the drainer body includes a hollow tubular body 1, a turned edge 13 is formed on an upper port of the tubular body 1 by extension, a sealing cover 4 is arranged at the upper port, and the drainer structure is characterized in that: the bottom of the sealing cover 4 is also provided with a cylinder body 5 with an internal hollow bottom opening, the side wall of the cylinder body is provided with a water filtering hole or a grid hole 51, and the cylinder body 5 is connected with the inner wall of the upper end opening of the tubular body 1 by adopting a lifting structure.

As shown in fig. 5, the lifting structure includes an internal thread 19 disposed on the inner wall of the upper end of the tubular body, an external thread 6 engaged with the internal thread is disposed on the outer circumferential surface of the tubular body, a water filtering hole or a grid hole 51 is disposed on the side wall of the tubular body 5, a sealing ring 52 is further sleeved above the external thread, and the outer diameter of the sealing ring 52 is slightly larger than the inner diameter of the tubular body 1.

The utility model adds a cylinder with an internal hollow bottom opening at the bottom of the sealing cover, and the side wall of the cylinder is provided with a water filtering hole or a grid hole, which can filter foreign matters to prevent blocking and dropping; in addition the utility model discloses an inside and outside screw-thread fit realizes that the lift of sealed lid reaches the switching function of downcomer.

In order to achieve a certain anti-dropping effect of the sealing cover, as shown in fig. 4, the external thread 6 of the present invention is divided into an upper section and a lower section, a section of non-threaded section 63 is reserved between the upper external thread 61 and the lower external thread 62, and the height of the non-threaded section 63 is greater than the height of the internal thread 19; the height of the unthreaded section 63 is greater than the pitch of the external thread and is in a non-multiple relationship with the pitch.

The cylinder 5 comprises an upper ring 55 and a lower ring 56, the upper and lower rings are connected by arranging a plurality of axial guide bars 57, a thread-shaped convex strip is wound on the peripheral surfaces of the axial guide bars to form an upper external thread 61, and a hollow part formed between the upper external thread 61 and the axial guide bars 57 forms the water filtering hole or the grid hole 51; the sealing ring 52 is sleeved on the upper ring 55, and the top of the upper ring 55 is connected with the sealing cover 4 into a whole; the outer peripheral surface of the lower ring 56 is provided with a thread-shaped groove to form the lower external thread 62.

The utility model discloses two sections external screw threads about the external screw thread adoption of barrel to go up and leave one section unthreaded section between external screw thread and the external screw thread down, unthreaded section highly is greater than the internal screw thread height, and unthreaded section highly is greater than the internal screw thread and highly can plays the anticreep function, and when last external screw thread upwards rotation breaks away from the internal thread, unthreaded section and internal thread do not have the cooperation relation, because the sealed lid of outer screw thread section blockking still can't break away from the mouth of a river down this moment, thereby play the function of anticree.

If the sealing cover needs to be taken out, the sealing cover needs to be lifted up, the upper end of the lower thread section is abutted to the upper end of the inner thread, then the sealing cover is slowly rotated to enable the screw mouth of the inner thread to be aligned with the screw mouth of the lower outer thread, and then the sealing cover can be slowly taken out; the utility model has the advantages that the thread-free section is arranged between the upper external thread and the lower external thread, and the height of the thread-free section is larger than that of the internal thread, so that when the upper external thread is separated from the internal thread, the lower external thread does not correspond to the internal thread; the height of the thread-free section is in a non-integral multiple relation of the thread pitch of the external thread, so that the difficulty of meshing the lower external thread and the internal thread is increased, and a better anti-falling effect is achieved.
