Description
Technical Field
[0001] The utility model relates to the technical field of wooden chopping boards, and particularly relates to a wooden chopping board with a knife sharpening device. Background Technique
[0002] A wooden chopping board, also known as a cutting board, is a common kitchen tool in cooking, used for cutting and preparing food ingredients. Common materials include oak, olive wood, bamboo, walnut wood, beech wood, maple wood, wutamu, rosewood, etc. Different woods have different hardness and antibacterial properties. Generally speaking, wooden chopping boards are relatively soft and relatively friendly to the blade.
[0003] Existing wooden chopping boards are equipped with a knife sharpening device. During cooking, the sharpness of the knife is crucial for food ingredient processing. A chopping board with a knife sharpening device allows users to sharpen the knife at any time while or after cutting vegetables, ensuring that the knife always remains sharp. There is no need to find a whetstone or knife sharpener separately, reducing the storage space requirement for kitchen utensils and avoiding the situation where the knife becomes dull due to forgetting or not being able to find the sharpening tool. A sharp knife cuts food ingredients more smoothly, reducing the cutting resistance caused by a dull knife, thereby reducing the risk of slipping the knife or cutting fingers due to excessive force.
[0004] However, after the knife sharpening device is used, the operator is prone to forget to dry the water stains, and the knife sharpening device is generally made of easily corroded materials such as metal. If the knife sharpening device adheres to water stains for a long time, impurities and minerals in the water stains may accelerate its corrosion process. Long-term corrosion will damage the surface and structure of the knife sharpening device, reducing its service life. Therefore, it is necessary to propose a wooden chopping board with a knife sharpening device to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a wooden chopping board with a knife sharpening device to solve the problems raised in the above background technique.
[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0008] After the bottom surface of the anti-slip mat is fitted to the external tabletop, the bottom surface of the knife sharpener can be made to fit the external tabletop, and the elastic force of the first spring can form a pulling force on the rotating block to one side, ensuring that the knife sharpener can fit the surface of the fixing plate, so as to limit the knife sharpener, facilitating the use of the knife sharpener for knife sharpening work. And by setting the protective plate, the hand of the operator without holding the knife can be separated from the knife sharpener, preventing the operator from accidentally hurting his own hand, thereby improving the safety performance of the device; by rotatably connecting the rotating block and the knife sharpener, and by pulling the first spring, the knife sharpener can be rotated to the bottom on the other side, so that the bottom surface of the knife sharpener fits the surface on the other side of the fixing plate. At the same time, by installing the rotating plate, the knife sharpener can be rotated to the bottom at one end again, so as to adjust the opening angle of the grinding edge opening provided on the knife sharpener. After the chopping board body is used up, by rotating the handle to the top of the chopping board body and turning the grinding edge of the knife sharpener downward, the water stains adhering to the surface of the grinding edge will automatically drip downward, preventing excessive water from remaining on the surface of the knife sharpener for a long time and affecting the use of the knife sharpener, thereby prolonging the service life of the knife sharpener.

A second spring is fixedly installed inside the fixing frame, and the other end of the second spring is fixedly connected to a clamping block. The clamping block extends out of the inside of the fixing frame and is engaged with the inner wall of the connecting block. A pull plate is provided at one end of the fixing frame, and the pull plate extends into the fixing frame and the second spring and is fixedly connected to the surface of one end of the clamping block.
[0010] Adopting the above technical solution, in this solution, the elastic force of the second spring itself can form a thrust on the clamping block to the other end, so as to facilitate the clamping block to be inserted into the inside of the connecting block to limit the connecting block, and further realize the limit fixation of the protective plate.
[0011] A further improvement of the technical solution of the present utility model lies in that: a pull ring is fixedly installed at one end of the pull plate.
[0012] Adopting the above technical solution, in this solution, by installing the pull ring, the contact area between the hand of the operator and the pull plate can be enlarged, so as to facilitate pulling the pull plate to one end and pulling the clamping block out of the inside of the connecting block, thereby facilitating the rotation operation of the connecting block and the protective plate.
[0013] A further improvement of the technical solution of the present utility model lies in that: a sliding plate is slidably installed on the top of the protection plate, and the inner wall of the sliding plate fits the surfaces at both ends of the protection plate. Limit blocks are fixedly installed at both ends of the protection plate. A plurality of sliding grooves matching the shapes of the limit blocks are formed in the inner wall of the sliding plate near both ends. Each limit block is respectively slidably connected to the inside of each sliding groove. A limit plate is rotatably installed on one side of the protection plate at the top of the connecting block. Convex blocks are attached to the surface of one side of the protection plate on both sides at the top of the limit plate. Each convex block is made of rubber material.
[0014] With the above technical solution, in this solution, by setting the limit blocks and the sliding grooves, the sliding trajectory of the sliding plate around the protection plate can be guided and limited. After rotating the protection plate 90 degrees to the bottom on the other side, the sliding plate can be moved to the periphery of the knife sharpener to block part of the position of the knife edge of the knife sharpener. And by rotating the limit plate 180 degrees and squeezing the convex blocks at the same time, the limit plate can be clamped between the two convex blocks to limit the limit plate, and at the same time, the sliding plate is limited, so that the knife sharpener can be protected to a certain extent.
[0015] A further improvement of the technical solution of the present utility model lies in that: a fixed frame is fixedly installed on the other side of the sliding plate. A baffle is inserted into the fixed frame. Rubber blocks are fixedly installed on the top of the fixed frame at both ends of the baffle. Each rubber block is made of rubber material. Each rubber block fits the surface at the top of the baffle. Partition strips are fixedly installed on the surface of the other side of the protection plate at both ends of the fixed frame.
[0016] With the above technical solution, in this solution, by inserting the baffle into the fixed frame, a part of the knife edge of the knife sharpener can be blocked from the bottom, further protecting the knife sharpener, and thus further extending the service life of the knife sharpener.
[0017] A further improvement of the technical solution of the present utility model lies in that: a plurality of anti-slip pads are attached to the surface at the bottom of the chopping board body.
