[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a disposable kitchen sink drain basket with a hard frame, comprising multiple semi-circular hollow tubes 1. Reinforcing mechanisms 2 are installed on the front and rear sides of the outer wall of each semi-circular hollow tube 1, for reinforcing the filter screen. Multiple adjusting mechanisms 3 are equidistantly installed inside each semi-circular hollow tube 1, for expansion and quick release. Each reinforcing mechanism 2 includes a threaded rod 201, installed on the front and rear sides of the outer wall of the semi-circular hollow tube 1. A worm gear 202 is fixedly connected to the upper middle part of the outer wall of the threaded rod 201. A movable plate 205 is threadedly connected to the outer wall of the threaded rod 201. Worms 203 are rotatably connected to the front and rear sides of the outer wall of the semi-circular hollow tube 1. Ring clips are fixedly connected to adjacent sides of the outer wall of the movable plate 205. A fixed disc 208 is installed at the bottom of the semi-circular hollow tube 1. A nylon mesh 210 is fixedly connected to the bottom of the fixed disc 208. Fixed short columns 204 are fixedly connected to the front and rear sides of the bottom of the semi-circular hollow tube 1. Slide grooves 306 are opened at the left and right ends of the top of the rear semi-circular hollow tube 1. The outer wall of the extrusion plate 301 is slidably connected to the inside of the slide groove 306. The front side of the inner wall of the moving plate 205 is slidably connected to the outer wall of the fixed short column 204. The fixed short column 204 can restrict the movement direction of the fixed short plate 206 and ensure that the fixed short plate 206 can move up and down smoothly. The bottom end of the threaded rod 201 is fixedly connected to the fixed short plate 206. The fixed short plate 206 can restrict the movement distance of the moving plate 205.

[0035] Specifically, a ring frame is formed by connecting multiple semi-circular hollow tubes 1 end to end, providing rigid support to ensure that the drain basket does not deform when placed at the edge of the sink. The edge of the nylon mesh 210 is pre-attached to the bottom of the fixed disc 208 with glue. Multiple slots 209 are opened on the top of the fixed disc 208. When the worm gear 203 is rotated, it drives the threaded rod 201 to rotate through meshing with the worm wheel 202. Since the bottom end of the threaded rod 201 is limited by the fixed short plate 206, and the inner wall of the moving plate 205 is slidably connected to the fixed short column 204, the moving plate 205 is forced to move along the outer wall of the threaded rod 201. The moving plate 205 drives the annular retaining teeth 207 to rise, so that the top retaining teeth of the annular retaining teeth are inserted into the slots 209 of the fixed disc 208, fixing the nylon mesh 210 to the bottom of the semi-circular hollow tube 1 and preventing the filter screen from falling off or shifting. The reverse worm gear 203 drives the annular locking tooth 207 to descend and disengage from the locking groove 209, releasing the lock on the fixed disc 208. The old nylon mesh 210 and the fixed disc 208 are removed, and only the disposable nylon mesh 210 is replaced. Users can discard it after use. While conveniently collecting and removing kitchen waste from the sink, there is no need to clean the stainless steel drain basket. The outer wall of the extrusion plate 301 is slidably connected to the inside of the slide 306. The front side of the inner wall of the moving plate 205 is slidably connected to the outer wall of the fixed short column 204. The fixed short column 204 can restrict the movement direction of the fixed short plate 206, ensuring that the fixed short plate 206 can move up and down smoothly. The bottom end of the threaded rod 201 is fixedly connected to the fixed short plate 206. The fixed short plate 206 can restrict the movement distance of the moving plate 205.

[0036] Reference Figure 6 , Figure 7 and Figure 8 The adjusting mechanism 3 includes an extrusion plate 301, which is equidistantly installed inside the rear semi-circular hollow tube 1. Multiple springs 305 are fixedly connected at equal intervals on adjacent sides of the outer wall of the extrusion plate 301. A serrated plate 302 is fixedly connected to the bottom of the extrusion plate 301. C-shaped plates 303 are installed on the left and right ends of the inner wall of the front semi-circular hollow tube 1. A serrated plate 304 is fixedly connected to adjacent sides of the outer wall of the C-shaped plate 303. The worm 203 is meshed with the worm wheel 202. Multiple slots 209 are equidistantly opened inside the fixed disc 208. The top of the annular tooth 207 engages with the inside of the slot 209. The engagement of the annular tooth 207 with the slot 209 can achieve the reinforcement effect. A nylon mesh 210 is fixedly connected to the bottom of the fixed disc 208.

[0037] Specifically, the spring 305 is compressed by squeezing the two extrusion plates 301 towards the center. Then, the tooth pitch of the two serrated plates 302 and 304 is adjusted by pulling the semi-circular hollow tube 1. After adjustment, the extrusion plates 301 are released, the spring 305 rebounds, pushing the serrated plates 302 and 304 to re-engage and lock the current diameter to adapt to different sizes of water tanks. When quick disassembly is required, the C-shaped plate 303 of the front semi-circular hollow tube 1 is aligned with the gap of the extrusion plates 301 of the rear semi-circular hollow tube 1. When inserted, the inclined surface of the C-shaped plate 303 pushes... The moving extrusion plate 301 moves to both sides, and the spring 305 is compressed. When the first sawtooth plate 302 and the second sawtooth plate 304 are aligned, the spring 305 rebounds instantly, so that the teeth of the two sawtooth plates are fully embedded, forming an axial lock, realizing quick installation and disassembly. The worm 203 is meshed with the worm wheel 202. Multiple slots 209 are equidistantly opened inside the fixed disc 208. The top of the annular tooth 207 engages with the inside of the slot 209. The engagement of the annular tooth 207 with the slot 209 can achieve a reinforcement effect. A nylon mesh 210 is fixedly connected to the bottom of the fixed disc 208.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The first sawtooth plate 302 and the second sawtooth plate 304 engage with each other, which can achieve the effect of fixing and adjusting. The bottom of the C-shaped plate 303 is fixedly connected to the bottom of the inner wall of the semi-circular hollow tube 1. The semi-circular hollow tube 1 can fix the C-shaped plate 303. The top of the threaded rod 201 is rotatably connected to the bottom of the inner wall of the semi-circular hollow tube 1. The outer wall of the worm 203 is rotatably connected to the inside of the semi-circular hollow tube 1. The semi-circular hollow tube 1 can support the worm 203 to rotate.

[0039] Specifically, the first sawtooth plate 302 and the second sawtooth plate 304 engage, achieving both fixing and adjustment. The bottom of the C-shaped plate 303 is fixedly connected to the bottom of the inner wall of the semi-circular hollow tube 1, which serves to fix the C-shaped plate 303. The top of the threaded rod 201 is rotatably connected to the bottom of the inner wall of the semi-circular hollow tube 1, and the outer wall of the worm gear 203 is rotatably connected to the inside of the semi-circular hollow tube 1, which supports the worm gear 203 to rotate.

[0040] Working principle: Multiple semi-circular hollow tubes 1 are connected end to end to form a ring frame, providing rigid support and ensuring that the drain basket does not deform when placed at the edge of the sink. The edge of the nylon mesh 210 is pre-glued to the bottom of the fixed disc 208 with glue. Multiple slots 209 are opened on the top of the fixed disc 208. When the worm gear 203 is rotated, it drives the threaded rod 201 to rotate through meshing with the worm wheel 202. Since the bottom end of the threaded rod 201 is limited by the fixed short plate 206, and the inner wall of the moving plate 205 is slidably connected to the fixed short column 204, the moving plate 205 is forced to rotate along the outer edge of the threaded rod 201. The wall moves, and the moving plate 205 drives the annular locking tooth 207 to rise, so that its top locking tooth is inserted into the slot 209 of the fixed disc 208, fixing the nylon mesh 210 to the bottom of the semi-circular hollow tube 1 to prevent the filter screen from falling off or shifting. The reverse worm gear 203 drives the annular locking tooth 207 to fall down and disengage from the slot 209, releasing the lock on the fixed disc 208. The old nylon mesh 210 and the fixed disc 208 are removed. Only the disposable nylon mesh 210 is replaced, which allows the user to throw it away after use. While conveniently collecting and removing kitchen waste in the sink, there is no need to wash the stainless steel drain basket.

[0041] The spring 305 is compressed by squeezing the two squeezing plates 301 towards the center. Then, the tooth pitch of the two serrated plates 302 and 304 is adjusted by pulling the semi-circular hollow tube 1. After the adjustment is completed, the squeezing plates 301 are released, and the spring 305 rebounds, pushing the serrated plates 302 and 304 to re-engage and lock the current diameter to adapt to different sizes of water tanks. When quick disassembly is required, the C-shaped plate 303 of the front semi-circular hollow tube 1 is aligned with the gap of the squeezing plate 301 of the rear semi-circular hollow tube 1. When inserted, the inclined surface of the C-shaped plate 303 pushes the squeezing plate 301 to move to both sides, and the spring 305 is compressed. When the serrated plates 302 and 304 are aligned, the spring 305 rebounds instantly, so that the teeth of the two serrated plates are fully embedded, forming an axial lock, realizing quick installation and disassembly.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
