Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically to a rotating knife holder. Background Technology

[0002] Traditional knife holders are made of a single welded metal piece, resulting in a large size and weight. Furthermore, their open sides make it easy for users to touch the blade, posing a safety hazard. This is especially true for knife holders used in the European and American markets, where the knives often have long, thin blades and are lighter than traditional kitchen knives. This makes the knives more prone to wobbling, and the blade can easily extend from the side of the holder, leading to accidental cuts. Utility Model Content

[0003] The purpose of this invention is to provide a safe and reliable knife holder.

[0004] The purpose of this utility model is achieved as follows.

[0005] A rotating knife holder includes a rotating base and a rotating base. A water receiving tray is detachably connected to the bottom of the rotating base. The rotating base is rotatably connected to the rotating base via the water receiving tray. A first cavity with an open top surface is provided at the center of the top of the rotating base. A protective sleeve is detachably connected to the top of the first cavity. The top and bottom of the protective sleeve are open. A top cover is detachably connected to the top of the protective sleeve. The top cover has several knife insertion holes. The first cavity and the protective sleeve form a laterally closed knife placement cavity. The knife insertion holes communicate with the knife placement cavity. At least one second cavity is provided around the first cavity on the top of the rotating base. The top surface of the second cavity is open. The bottom of the first cavity and the second cavity are respectively provided with corresponding water receiving trays and drain outlets.

[0006] Furthermore, the inner wall of the first cavity extends upward to form a base and a first annular wall. The outer side of the first annular wall is provided with a first annular groove. The first annular wall is inserted into the protective sleeve until the bottom surface of the protective sleeve and the bottom surface of the first annular groove abut against each other. The bottom of the protective sleeve and the first annular wall are inserted to form the detachable connection between the first cavity and the protective sleeve.

[0007] Furthermore, a second annular wall extends downward from the bottom surface of the top cover. The outer side of the second annular wall is provided with a second annular groove. The second annular wall is inserted into the top of the protective sleeve until the top surface of the protective sleeve and the bottom surface of the second annular groove abut against each other. The insertion of the top of the protective sleeve and the second annular wall constitutes the detachable connection between the protective sleeve and the top cover.

[0008] Furthermore, the base extends downward along the bottom surface and contour with a third annular wall. The inner side of the third annular wall has several arc-shaped protrusions. The top of the water receiving tray has a fourth annular wall. The outer side of the fourth annular wall has a third annular groove. The side wall of the third annular groove has several arc-shaped grooves. The fourth annular wall is inserted into the third annular wall, and the third annular wall is placed in the third annular groove until the bottom surface of the third annular wall and the bottom surface of the third annular groove abut together. The arc-shaped protrusions are engaged with the arc-shaped grooves to form the detachable connection between the base and the water receiving tray.

[0009] Furthermore, the bottom of the first cavity is open to form the drain outlet, and the water receiving tray has radially arranged reinforcing ribs from the center to the periphery. The height of the top of the reinforcing ribs gradually decreases from the center of the water receiving tray to the periphery, and the bottom of the first cavity abuts against the reinforcing ribs. The open bottom of the first cavity, in conjunction with the water receiving tray, allows the blade placement cavity to accommodate longer blades.

[0010] Furthermore, a rotating base is located at the center of the bottom of the water receiving tray, with a shaft hole inside the rotating base. A convex shaft is located at the center of the rotating base. The water receiving tray sits on the rotating base, and the convex shaft is inserted into the shaft hole. The water receiving tray drives the rotating base to rotate around the convex shaft. The water receiving tray and the rotating base are not easily separated during rotation.

[0011] Furthermore, the rotating base includes a fixed base, a rotating base, and ball bearings. The fixed base has an annular groove, and the rotating base is arranged in a circular shape within the annular groove. The rotating base and the annular groove are in contact through ball bearings. The fixed base has the aforementioned convex shaft at its center, and the water receiving tray sits on the rotating base. The rotating base and the water receiving tray rotate around the convex shaft as a pivot point, preventing the rotating base and the water receiving tray from detaching from the rotating base due to centrifugal force.

[0012] Furthermore, a fifth annular wall extends downward from the bottom of the water receiving tray. This fifth annular wall is positioned outside the fixed base, which has a support portion within the annular groove. A protrusion extends downward from the bottom of the water receiving tray within the fifth annular wall, with the bottom surface of the protrusion slidingly contacting the top surface of the support portion. The support portion has a centrally located convex shaft. The water receiving tray experiences some resistance during rotation and cannot rotate on its own. It can quickly stop after rotating under external force.

[0013] Furthermore, the protrusion is shaped like a cross with the center of the water receiving tray, and the support part has several evenly spaced perforated sections. This reduces the contact area between the protrusion and the support part, thus lowering the rotational resistance.

[0014] Furthermore, the rotating base, top cover, and drip tray are made of plastic, while the protective sleeve is a metal protective sleeve. There is one second cavity surrounding the first cavity, and the second cavities are divided into multiple chambers by a first partition. Each chamber has several through holes at its bottom to form the drain outlet, and each chamber has several second partitions at its bottom. The first and second partitions work together to prevent utensils from tipping over into the second cavity.

[0015] The protective sleeve and the first cavity of this invention cooperate to prevent side contact with the blade, reducing safety hazards. Assembly and disassembly of the base, protective sleeve, top cover, water tray, and rotating base are simple and easy. The detachable blade holder design facilitates maintenance and replacement of damaged parts. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1, see Figure 1-4 As shown, a rotating knife holder includes a rotating base 1, a protective sleeve 2, a top cover 3, a water receiving tray 4, and a rotating base 5.

[0022] The rotating base 1 has a first cavity 11 with an open top surface at its top center. At least one second cavity 12 is located around the first cavity 11 at the top of the rotating base 1. The second cavities 12 are also open at their top surfaces. The bottoms of the first and second cavities 11 and 12 are respectively provided with corresponding water receiving trays 4 and drain outlets 13. Specifically, the inner wall of the first cavity 11 extends upwards from the base to form a first annular wall 14. The outer side of the first annular wall 14 has a first annular groove 15, and the outer side of the top of the first annular groove 15 has a first guide slope 16. A third annular wall 17 extends downwards along the bottom surface of the base, and the inner side of the third annular wall 17 has several arc-shaped protrusions 18. In this embodiment, the bottom of the first cavity 11 is open, forming the drain outlet 13. A second cavity 12 is located and surrounds the first cavity 11. The second cavities 12 are divided into multiple chambers 120 by a first partition 121. Each chamber 120 has several through holes 122 at its bottom to form the drain outlet 13, and each chamber 120 has several second partitions 123 at its bottom. The rotating base 1 is integrally injection molded from plastic. The top surface of the first partition 121 is lower than the top surface of the second cavity 12, and the top surface of the second partition 123 is much lower than the top surface of the first partition 121, that is, the top surface of the second partition 123 is slightly higher than the bottom surface of the second cavity 12. Cutlery such as knives, forks, and chopsticks are placed in the chambers 120, with the bottom of the utensil abutting against the second partition 123 and the top of the utensil abutting against the side of the second cavity 12. The protective sleeve 2 is open at the top and bottom, and its shape is adapted to the shape of the first cavity 11. The protective sleeve 2 is a metal protective sleeve, such as an aluminum protective sleeve, an aluminum alloy protective sleeve, a stainless steel protective sleeve, or a copper alloy protective sleeve.

[0023] The top of the first cavity 11 and the protective sleeve 2 are detachably connected. Specifically, the first annular wall 14 is inserted into the protective sleeve 2 until the bottom surface of the protective sleeve 2 abuts against the bottom surface of the first annular groove 15, and the bottom of the protective sleeve 2 and the first annular wall 14 are inserted to form the detachable connection between the first cavity 11 and the protective sleeve 2. The first guide slope 16 guides the protective sleeve 2 to fit onto the first annular wall 14. Preferably, the protective sleeve 2 and the first annular groove 15 are interference-fitted.

[0024] The top cover 3 extends downward from its bottom surface to form a second annular wall 31. The outer side of the second annular wall 31 has a second annular groove 32, and the bottom of the second annular wall 31 has a second guide slope 33 facing the second annular groove 32. The top cover 3 has several inserting slots 30. The top cover 3 is integrally injection molded from plastic.

[0025] The top cover 3 and the top of the protective sleeve 2 are detachably connected. Specifically, the second annular wall 31 is inserted into the top of the protective sleeve 2 through the second guide slope 33 until the top surface of the protective sleeve 2 and the bottom surface of the second annular groove 32 abut against each other. The insertion of the top of the protective sleeve 2 and the second annular wall 31 constitutes the detachable connection between the protective sleeve 2 and the top cover 3. The first cavity 11 and the protective sleeve 2 constitute a laterally closed blade placement cavity 10. The blade insertion port 30 communicates with the blade placement cavity 10. The blade is inserted from the insertion port, and the blade is placed in the blade placement cavity 10. The handle of the blade is placed on the top cover 3. Preferably, the second annular wall 31 and the second annular groove 32 are interference-fitted. The top cover 3 is not easily detached.

[0026] The water receiving tray 4 and the rotating base 1 are detachably connected at the bottom. Specifically, the top of the water receiving tray 4 is provided with a fourth annular wall 41, the outer side of the fourth annular wall 41 is provided with a third annular groove 42, and the side wall of the third annular groove 42 is provided with a plurality of arc-shaped grooves 43. The fourth annular wall 41 is inserted into the third annular wall 17, and the third annular wall 17 is placed in the third annular groove 42 until the bottom surface of the third annular wall 17 and the bottom surface of the third annular groove 42 abut against each other. The arc-shaped protrusion 18 is engaged with the arc-shaped groove 43 to form the detachable connection between the base and the water receiving tray 4. The bottom of the water receiving tray 4 extends downward with a fifth annular wall 44, and the bottom of the water receiving tray 4 extends downward with a protrusion 45 within the fifth annular wall 44.

[0027] The water receiving tray 4 is provided with radially arranged reinforcing ribs 46 from the center to the periphery, and the height of the top of the reinforcing ribs 46 gradually decreases from the center of the water receiving tray 4 to the periphery. After the water receiving tray 4 and the rotating base 1 are connected, the bottom of the first cavity 11 abuts against the reinforcing ribs 46.

[0028] A rotating base 47 is located at the center of the bottom of the water receiving tray 4. A shaft hole 48 is provided within the rotating base 47. A convex shaft is located at the center of the rotating base 5. The water receiving tray 4 sits on the rotating base 5, and the convex shaft is inserted into the shaft hole 48. The water receiving tray 4 drives the rotating base 1 to rotate around the convex shaft. In this embodiment, the reinforcing ribs 46 are arranged in a cross shape, and all reinforcing ribs 46 are fixedly connected to the rotating base 47. A protrusion 45 extends from the bottom of the shaft hole 48.

[0029] The rotating base 5 includes a fixed base 6, a rotating base 7, and ball bearings 8. The fixed base 6 has an annular groove 61, and the rotating base 7 is arranged in a ring shape within the annular groove 61. The rotating base 7 and the annular groove 61 are in contact through the ball bearings 8. The fixed base 6 has a convex shaft 62 at its center, and the water receiving tray 4 sits on the rotating base 7. Specifically, the fifth annular wall 44 is located outside the fixed base 6. The fixed base 6 has a support portion 63 within the annular groove 61. The bottom surface of the protrusion 45 and the top surface of the support portion 63 are in sliding contact. The support portion 63 has the convex shaft 62 at its center, and the water receiving tray 4 sits on the top surface of the rotating base 7. In this embodiment, the protrusion 45 is cross-shaped with the center of the water receiving tray 4, and the support portion 63 is evenly provided with several hollowed-out portions 64, which reduces the contact area between the protrusion 45 and the support portion 63, thereby reducing rotational friction resistance.

[0030] The rotating base 5 and the water tray 4 are detachable, making it easy to remove the water tray 4 and empty the accumulated water. The top cover 3, protective sleeve 2, rotating base 1, water tray 4 and rotating seat 7 rotate synchronously relative to the fixed base 6, so that the knife handle on the top cover 3 or the utensils (knives, forks, chopsticks, etc.) in the second cavity 12 can be moved to a convenient position for picking up and putting down.
