Technical Field

[0001] The utility model relates to the technical field of kitchen knives, in particular to a kitchen knife with a counterweight. Background Art

[0002] A kitchen knife is a kitchen utensil, which is mainly used for cutting food or carving food. It can be divided into stainless steel knives and iron knives, and can also be divided into Chinese kitchen knives, Japanese kitchen knives and Western kitchen knives. Some existing household kitchen knives are of fixed weight. When it is necessary to cut meat of different hardness, multiple knives of different weights must be equipped, which will cause great inconvenience to the user.

[0003] In order to solve the above problem, the patent document with the publication number CN201235538Y discloses a dual-purpose chopping and cutting kitchen knife with a detachable counterweight, which is composed of a blade and a counterweight. A connecting lock is designed in the middle of the blade back, and the counterweight has a mounting groove that matches the blade back. There is an installation lock pin in the middle of the groove. The counterweight can be connected to the blade body through the connecting lock in the middle of the blade back, the mounting groove on the counterweight, and the installation lock pin in the mounting groove. A connecting lock is designed in the middle of the blade back of an ordinary dual-purpose chopping and cutting knife, and a counterweight with a certain weight, a mounting groove and a connecting lock pin is processed at the same time. When chopping chicken nuggets, the counterweight is connected to the blade back and the connecting lock in the middle of the blade back as a whole through the mounting groove, the connecting lock pin, the blade back, and the connecting lock in the middle of the blade back; when cutting ordinary vegetables, the counterweight is removed from the blade back.

[0004] However, the above patent document has the following defects: first, the counterweight is not installed stably. When the kitchen knife is raised and lowered, the loosened locking pin will slide along the installation groove, causing the blade and the counterweight to separate, so there is a safety hazard of "counterweight flying out"; second, the counterweight and the kitchen knife body produce collision sounds due to relative sliding; third, the counterweight is a cylindrical structure, which is not compatible with the sheet-like blade, so that after the two are combined, the overall appearance looks very bulky and lacks coordination.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0031] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper surface", "lower surface", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "forward", "reverse", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] like Figure 1 , 2 As shown in Figure 3, a kitchen knife with a counterweight comprises a kitchen knife body 1, the lower side of the kitchen knife body 1 is a blade 2, one end of the kitchen knife body 1 is provided with a handle 3, and the upper side of the kitchen knife body 1 is provided with a counterweight 4. The kitchen knife of the present application is provided with a counterweight to increase the impact force, which is convenient for cutting hard ingredients such as bone-in meat and turtle back. The "cut" here actually means "chop".

[0033] The counterweight 4 and the kitchen knife body 1 are detachably connected. The present application adopts a detachably connected structure, and there are two ways of using the kitchen knife: when cutting vegetables, the counterweight is removed; when chopping vegetables, the counterweight is retained. This makes it more convenient to use the kitchen knife. When using the kitchen knife to cut soft ingredients such as green vegetables and green onions, it does not require too much impact force to achieve cutting, so the counterweight can be removed. After removing the counterweight, it is more convenient to cut vegetables.

[0034] The bottom surface of the counterweight 4 is provided with an insertion groove 5, and the side surface of the counterweight 4 is provided with a screw hole 6 connected with the insertion groove 5, and a fastening screw 7 is provided in the screw hole 6, and a rotation adjustment handle 8 is provided at the end of the fastening screw 7. After the counterweight 4 is plugged into the upper side of the kitchen knife body 1, the fastening screw 7 is rotated to fix the counterweight 4 to the kitchen knife body 1 through the fastening screw 7.

[0035] like Figure 4 , 5 As shown in FIG. 6 , the counterweight 4 includes a front side plate 41, a rear side plate 42 and an upper side plate 43. The upper side plate 43 connects the front side plate 41 and the rear side plate 42 together. The gap between the front side plate 41 and the rear side plate 42 is the plug-in slot 5. The front side plate, the rear side plate and the upper side plate are enclosed to form a sheet structure. The counterweight is designed as a sheet structure to increase the adaptability of the counterweight to the kitchen knife body 1, so that the overall appearance looks more coordinated after the two are combined.

[0036] The length of the rear side plate 42 is greater than that of the front side plate 41. The excess portion of the rear side plate 42 relative to the front side plate 41 is called a limit plate 44. A limit block 45 is provided on the surface of the limit plate 44. A limit hole 9 is provided on the kitchen knife body 1. The limit block 45 is located in the limit hole 9. The limit hole 9 is used to limit the upward and downward movement of the limit block 45.

[0037] The kitchen knife body is also provided with an introduction hole, the introduction hole partially overlaps with the non-circular hole, and the limit block is non-circular.

[0038] The limiting hole is a non-circular hole. Specifically, the limiting hole 9 is an elongated hole, more specifically, the elongated hole is a rectangular hole. The upper side 10 and the lower side 11 in the elongated hole are parallel to each other. The kitchen knife body 1 is also provided with an introduction hole 12. The introduction hole 12 partially overlaps with the elongated hole. The introduction hole is a circular hole and the diameter of the circular hole is greater than the distance between the upper side and the lower side of the rectangular hole. The upper surface and the lower surface of the limiting block 45 are parallel planes. The limiting block 45 extends into the introduction hole 12 to adjust its posture and then enters the elongated hole. The elongated hole is used to limit the rotation of the limiting block 45. The above-mentioned structural form further improves the safety of use, can effectively avoid the separation of the counterweight from the kitchen knife body during use, and prevent the phenomenon of "counterweight flying out". The limit hole is used to limit the upward and downward movement of the limit block, which not only eliminates the safety hazard of "counterweight flying out" when the kitchen knife is used, but also avoids the collision sound caused by the relative sliding of the counterweight and the kitchen knife body.

[0039] The shape of the limit block 45 in the limit hole 9 of the present application is only the best implementation mode of the present application. Of course, the limit block 45 and the limit hole 9 can also be other shapes, such as triangle, polygon, etc., which are all within the protection scope.

[0040] In addition, the width of the front side plate is smaller than that of the rear side plate. The end surface of one end of the front side plate is an inclined surface. In this structural form, when installing the counterweight, the upper side of the kitchen knife body can first contact the surface of the rear side plate and slide along the surface of the rear side plate. The upper side of the kitchen knife body is guided by the rear side plate to extend into the insertion groove 5 on the bottom surface of the counterweight 4, which greatly facilitates the installation of the counterweight.

[0041] The kitchen knife body 1 is also provided with a fixing hole 13. When the limiting block 45 slides along the elongated hole to the end of the elongated hole, the screw hole 6 corresponds to the fixing hole 13, and the fastening screw 7 extends into the fixing hole 13. The fastening screw 7 is extended into the fixing hole 13 on the kitchen knife body 1. The end of the elongated hole in the present application plays a limiting role in the installation of the counterweight, so that the screw hole 6 can be easily aligned with the fixing hole 13, making the installation and fixation more convenient.

[0042] Working principle: In terms of usage functions, kitchen knives are divided into three functions: "cutting", "slicing" and "chopping". The front section of the blade is used to achieve the "cutting" function, the middle section of the blade is used to achieve the "slicing" function, and the back section of the blade is used to achieve the "chopping" function. When realizing the "cutting" and "slicing" functions, the counterweight should be removed, and when realizing the "chopping" function, the counterweight should be retained.

[0043] In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without contradiction. Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limiting the utility model. Those skilled in the art may change, modify, replace and modify the above embodiments within the scope of the utility model.
