Description

Technical Field

[0001] The utility model relates to the technical field of knife sharpening tools, and more specifically to a knife sharpening device. Background Art

[0002] A knife sharpener, also known as a whetstone, is a tool. The blade of a knife becomes blunt after use, and it needs to be sharpened by pulling it back and forth on the sharpener. Its materials include diamond, zirconium oxide, etc.

[0003] The traditional way of sharpening knives with a whetstone requires the addition of whet oil or water, which is not very clean and sanitary, so it is not very popular. The current knife sharpeners on the market are composed of motors, grinding wheels, pulleys, etc. Although they are water-free and mud-free, more sanitary, and easy to use, they are too expensive, have a complicated structure, and are very inconvenient to use.

[0022] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figure 1 and Figure 2 As shown, this embodiment discloses a knife sharpening device 10, comprising: a main body 11; two knife sharpening parts 20, respectively arranged at the two ends of the main body 11; wherein the knife sharpening part 20 comprises a rotating shaft 21, a grinding disc 22 and a grinding wheel 23, the grinding disc 22 is used to polish the cutting edge of the tool, the grinding disc 22 is detachably fixed on the grinding wheel 23, the grinding wheel 23 is rotatably mounted on the end of the main body 11 through the rotating shaft 21, the rotating shafts 21 of the two grinding wheels 23 are independently arranged, and the two grinding wheels 23 can rotate independently relative to the main body 11.

[0024] Through the design of independent rotation of the double-sided grinding wheel 23, since the independent grinding wheel 23 can have different rotation speeds when rotating, better direction control can be achieved, and it is more conducive to adjusting the movement direction when polishing the tool with reciprocating motion, and can better fit the tool to be polished; when the grinding device 10 is used on a support surface, the movement above the support surface is achieved by applying force to the main body 11, so that the two grinding wheels 23 can rotate independently relative to the main body 11, and since the grinding disc 22 is fixed on the independently rotatable grinding wheel 23, the grinding wheel 23 can rotate synchronously with the grinding disc 22 while rotating, so as to polish the tool to be polished.

[0025] Among them, the two ends of the main body 11 are provided with mounting positions 15, and the mounting positions 15 are fixed with bearings 16. The rotating shaft 21 passes through the bearings 16 and cooperates with the limiting member 12 to limit the position. The setting of the bearings 16 can reduce the friction coefficient of the rotating shaft 21 during the movement and ensure the accuracy of its rotation, so that the rotation of the grinding wheel 23 is smoother. A threaded hole (not shown in the figure) is provided on one side of the grinding wheel 23, and one end of the rotating shaft 21 is detachably fixedly connected to the threaded hole. The rotating shaft 21 is directly installed on the grinding wheel 23 through the threaded hole, which is convenient for the installation and removal of the rotating shaft 21; of course, according to actual needs, the rotating shaft 21 and the grinding wheel 23 can also be made into one piece, which is conducive to reducing the parts that need to be assembled. One end of the rotating shaft 21 is fixedly connected to the sharpening wheel 23, and the other end of the rotating shaft 21 is provided with a limiting groove 211. The main body 11 is provided with a limiting member 12, and the limiting member 12 cooperates with the limiting groove 211 to limit the rotating shaft 21. The limiting member 12 is installed inside the main body 11. While ensuring the cooperation with the limiting groove 211, the limiting member 12 can be effectively hidden, so that the overall sharpening device 10 is more concise and beautiful.

[0026] Among them, the limiting member 12 includes at least one latch 121, and the latch 121 can be set in an even number. The latch 121 is symmetrically arranged around the rotating shaft 21. A limiting hole 13 is provided on the main body 11. The latch 121 is limited by cooperating with the limiting groove 211 through the limiting hole 13. An arc-shaped recess 122 is provided at the end of the latch 121 that cooperates with the limiting groove 211. The arc-shaped recess 122 cooperates with the limiting groove 211 to better limit and fix, so that the latch 121 and the rotating shaft 21 can better limit and cooperate.

[0027] Among them, the outer surface of the main body 11 is provided with an annular groove 14, the limiting hole 13 is provided at the bottom of the annular groove 14, and a decorative ring 17 is installed on the annular groove 14. The decorative ring 17 not only has the function of aesthetic decoration, but also can effectively limit the latch 121, effectively preventing the latch 121 from falling off from the limiting hole 13 during use, and while fixing the latch 121, it also has the function of limiting the hand holding of the main body 11, ensuring the correctness of holding the knife sharpening device 10. The decorative ring 17 is made of rubber or silicone material, which can effectively increase the friction between the hand and the main body 11 of the knife sharpening device 10, making the operation of the knife sharpening device 10 more stable.

[0028] Among them, the grinding wheel 23 is provided with an annular boss 231, which is arranged on the surface of one side matching with the rotating shaft 21. The annular boss 231 is arranged along the edge of the threaded hole, which can effectively avoid the grinding wheel 23 from generating friction with the main body 11 during rotation, and effectively avoid the wear of the relative surfaces between the main body 11 and the grinding wheel 23, thereby improving the overall durability of the grinding device 10.

[0029] Among them, a fixing layer 24 is provided between the grinding wheel 23 and the grinding disc 22. The fixing layer 24 is an adhesive sheet or a magnetic sheet. The grinding disc 22 is adhered to the grinding wheel 23 by an adhesive sheet, or is directly installed on the grinding wheel 23 by magnetic attraction of a magnetic sheet, so that the grinding disc 22 with severe wear can be replaced separately, which can effectively reduce the relevant use cost.

[0030] Among them, the sharpening wheel 23 is made of metal material, and can be optionally made of aluminum, copper or stainless steel. The sharpening wheel 23 made of aluminum is more durable. A rubber ring or a silicone ring is sleeved on the outer circumference of the sharpening wheel 23 to effectively reduce the noise when the sharpening wheel 23 rotates on the supporting surface; the main body 11 is made of wooden material, and the main body 11 of wooden material can effectively reduce the overall weight of the sharpening device 10, making the sharpening device 10 more portable and further improving the overall texture of the sharpening device 10; optionally, the grinding discs 22 of the two sharpening parts 20 are made of different materials to better adapt to the polishing of different knives.

[0031] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
