Description

Technical Field

[0001] This utility model relates to a knife sharpener, specifically to a technology that allows for quick and convenient adjustment of the blade angle. Background Technology

[0002] Knife sharpeners are frequently used in the kitchen. The sharpening stone is a common stone, which users can use to sharpen their knives.

[0003] To facilitate storage and organization, various types of sharpening devices have emerged in the prior art, each with a wide range of functions. For example, they can be set at different angles to facilitate sharpening, or the sharpening blade can be hidden during use to avoid long-term exposure to the outside and affecting aesthetics.

[0004] However, existing sharpeners typically have two prominent problems: when the sharpening stone is sealed in a container, it needs to be opened frequently for sharpening, making it impossible to keep the sharpening stone inside the casing during sharpening, which would reduce the impact of sharpening debris on the surrounding environment; and secondly, the angle adjustment of the sharpening blades is inconvenient, especially the inability to quickly adjust the angle of multiple positions, making it difficult to sharpen multiple sets of blades simultaneously. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and thus provide a technology for quickly adjusting the angle of the whetstone or the clamping force.

[0006] To achieve the above objectives, this utility model provides an adjustable angle sharpener, which includes a housing, an adjustment knob, a gear assembly, a moving rod, and a sharpening blade.

[0007] The outer casing has an opening for sharpening tools;

[0008] The adjustment knob is rotatably mounted on the outside of the housing;

[0009] The gear assembly is located inside the housing and is connected to the adjustment knob.

[0010] The movable rod cooperates with the gear assembly, and the movable rod moves laterally under the action of the gear assembly;

[0011] The grinding blade is connected to the moving rod. When the moving rod moves laterally, it causes the grinding blade to swing, thereby adjusting the grinding angle. The grinding blade corresponds to the opening for grinding.

[0012] Preferably, the openings for sharpening the blade are in multiple sets along the transverse direction, and an equal number of sharpening blades are provided accordingly.

[0013] Preferably, the gear assembly includes a first drive gear and a connecting rod connected in sequence, with the end of the connecting rod connected to the adjustment knob; the first drive gear meshes with the first elongated tooth of the first moving rod to drive the moving rod to move laterally.

[0014] Preferably, the movable rod has a sliding rod portion, and the outer casing has a guide sliding groove inside, with the sliding rod portion cooperating with the guide sliding groove.

[0015] Preferably, the connecting rod is sequentially connected to a first bevel gear, an intermediate bevel gear, a second bevel gear, and a second drive gear, and the second drive gear engages with the second elongated tooth portion of the second moving rod; the moving direction of the second moving rod is synchronous and opposite to the moving direction of the first moving rod.

[0016] Preferably, it also includes a fixing rod, which has a central grinding block, and grinding blades are respectively arranged on both sides of the central grinding block, with the grinding blades forming different driving directions.

[0017] Preferably, the lower interior of the outer casing has a fixing part, and the grinding blade is hinged to the fixing part via a connecting post.

[0018] Preferably, the grinding blade has a main grinding part and an opening, and the fixing rod is disposed at the position of the opening.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By adjusting the knob, the gear assembly moves, which in turn moves the moving rod laterally. This causes the sharpening blade to deflect and adjust its angle, thus facilitating the sharpening action.

[0021] 2. When sharpening the blade, place it in the sharpening opening. The sharpening action takes place inside the outer casing, which helps to collect debris and prevent pollution of the surrounding environment.

[0022] 3. Through the cooperation of gears and racks, the moving rod is driven to move laterally, which causes the grinding blade to swing and thus achieve angle adjustment.

[0023] 4. By using the first bevel gear, the intermediate bevel gear, the second bevel gear, and the second drive gear, two sets of moving rods with different opposite movements are designed. This allows the two sets of grinding blades to work simultaneously and move towards the center or away from each other at the same time, thus achieving the simultaneous adjustment function of the two sets of grinding blades.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1:

[0039] like Figure 1 , 2 As shown, this embodiment provides an adjustable angle sharpener, which includes a housing 10, an adjustment knob 20, a gear assembly 30, a moving rod 40, and a sharpening blade 50;

[0040] The outer casing 10 has a sharpening opening 11;

[0041] The adjustment knob 20 is rotatably disposed on the outside of the housing 10;

[0042] The gear assembly 30 is located inside the housing 10 and is connected to the adjustment knob 20;

[0043] The movable rod 40 cooperates with the gear assembly 30, and the movable rod 40 moves laterally under the action of the gear assembly 30.

[0044] The grinding blade 50 is connected to the moving rod 40. When the moving rod 40 moves laterally, it causes the grinding blade 50 to swing, thereby adjusting the grinding angle. The top of the grinding blade 50 corresponds to the grinding hole 11.

[0045] In practical applications, place the blade into the sharpening hole 11, and then the blade contacts the sharpening blade 50 and performs a back-and-forth sharpening operation. When the angle needs to be adjusted, rotate the adjustment knob 20, and the gear assembly 30 moves to drive the moving rod 40, which in turn moves the sharpening blade 50 to achieve angle adjustment.

[0046] Preferably, the grinding blade 50 has a driving post 54 in its central region, and the moving rod 40 has a driving notch 44, which engages with the driving post 54; the bottom of the grinding blade 50 is hinged to the outer shell 10. When the moving rod 40 moves, the driving notch 44 causes the driving post 54 and the grinding blade 50 to deflect and swing as a whole, that is, to deflect around the hinged position at the bottom, so as to achieve angle adjustment.

[0047] Preferably, the openings 11 for sharpening are arranged in multiple groups along the transverse direction, and an equal number of sharpening blades 50 are provided accordingly. The sharpening blades 50 at different positions can be made of different types of materials to meet the needs of different types of sharpening.

[0048] like Figure 3 , 4 As shown, preferably, the gear assembly 30 includes a first drive gear 31 and a connecting rod 32 connected in sequence, with the end of the connecting rod 32 connected to the adjustment knob 20; the first drive gear 31 meshes with the first elongated tooth 421 of the first moving rod 42 to drive the first moving rod 42 to move laterally. Through the cooperation of the gear and rack, when the first drive gear 31 rotates, it drives the first moving rod 42 to move horizontally, thereby causing the grinding blade 50 to deflect and swing to achieve angle adjustment.

[0049] like Figure 2 As shown, preferably, the movable rod 40 has a sliding rod portion 41, and the outer casing 10 has a guide sliding groove 12 inside, with the sliding rod portion 41 cooperating with the guide sliding groove 12. The cooperation between the sliding rod portion 41 and the guide sliding groove 12 makes the movable rod 40 more stable when sliding and less prone to disengaging from its position.

[0050] like Figure 5 As shown, preferably, the lower interior of the outer casing 10 has a fixing part 13, and the grinding blade 50 is hinged to the fixing part 13 via a connecting post 53. The bottom of the grinding blade 50 is hinged via the connecting post 53, while the middle region of the grinding blade 50 can be deflected by the movement rod 40 to achieve angle adjustment.

[0051] Preferably, the grinding blade 50 has a main grinding portion 51 and an opening portion 52, with the fixing rod 60 positioned at the opening portion 52. The opening portion 52 is provided so that the grinding blade 50 will not touch the fixing rod 60 in the middle when it swings.

[0052] Second embodiment:

[0053] like Figure 4 As shown, preferably, the connecting rod 32 is sequentially connected to the first bevel gear 33, the intermediate bevel gear 34, the second bevel gear 35, and the second drive gear 36. The second bevel gear 35 and the second drive gear 36 are coaxially connected. When the second bevel gear 35 rotates, it simultaneously drives the second drive gear 36 to rotate as well.

[0054] The second drive gear 36 engages with the second elongated tooth 431 of the second moving rod 43; the moving direction of the second moving rod 43 is synchronous and opposite to the moving direction of the first moving rod 42.

[0055] This causes the second moving rod 43 and the first moving rod 42 to move in opposite directions. The second moving rod 43 can also drive the grinding blade 50 to move, thus creating a situation where the second moving rod 43 and the first moving rod 42 respectively drive the grinding blade 50 to move closer together or away from each other.

[0056] like Figure 5 As shown, preferably, it also includes a fixing rod 60, which has a central grinding block 61. Grinding blades 50 are respectively arranged on both sides of the central grinding block 61, and the grinding blades 50 form different driving directions. The grinding blades 50 arranged on both sides are respectively connected to the second moving rod 43 and the first moving rod 42.

[0057] Preferably, the two sets of sharpening tools are connected by openings 11 to form a structure. Each structure is provided with two sets of sharpening blades 50 that can be driven to move simultaneously. The middle position of the two sets of sharpening blades 50 is a middle sharpening block 61. In this way, the blade can be placed on either sharpening blade 50. In addition, the distance between the sharpening blade 50 and the middle sharpening block 61 changes after the angle of the sharpening blade 50 is adjusted, which can adjust the clamping force with the blade, thus facilitating the sharpening operation.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
