Description

Knife sharpener

Technical Field

The utility model belongs to the technical field of the sharpener, a sharpener is related to.

Background

After the knife such as kitchen knife, outdoor knife, scissors and the like is used for a long time, the knife edge of the knife is not sharp. A knife sharpener is an apparatus for sharpening a knife and sharpening the edge of the knife. Such as chinese patent application No.: CN201821025277 discloses a box of whetting a knife, including the receiver that has the cavity, place whetstone and the upper cover of lid on the receiver in the receiver, a plurality of lugs have on the medial surface of receiver, interior bottom surface has a plurality of sand grips, when whetstone sets up on the receiver, the lug supports to the lateral surface of whetstone and leans on, the sand grip supports to the bottom surface of whetstone and leans on, the lug is fixed a position the whetstone, the sand grip is used for making the interior bottom surface time of whetstone bottom surface and receiver form the space of water storage.

Although foretell receiver can carry out the stable stay to the whetstone, the supporting member to the whetstone on the receiver is more, the structure is comparatively complicated, especially the whetstone is placed in the receiver, not with the receiver tight fit, can follow the interior separation of receiver in order to realize the whetstone, there is the clearance between the lateral wall of whetstone and the lug, the whetstone can take place to remove when using the receiver relatively, based on the material of whetstone and receiver, after long-time the use, the supporting member on the receiver can be worn and torn by the whetstone, the whetstone can't stabilize spacing on the receiver.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a sharpener, the utility model aims to solve the technical problem that: the existing knife sharpener can not stabilize and limit the sharpening stone.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a sharpener, includes that base, lid establish on the base and have lid and the whetstone of cavity, the lid has the communicating opening with the cavity, its characterized in that, the whetstone sets up in the lid, be equipped with the limit structure who restricts whetstone horizontal position when the lid opening up between the interior bottom surface of whetstone and lid.

The working direction of the knife sharpener is that the opening of the cover body is arranged upwards. The whetstone sets up in the cavity of lid, its gravity is vertical to be exerted downwards to the lid on the interior bottom surface, limit structure that sets up on the bottom surface can carry out the stable support to the whetstone in the lid, the whetstone can eliminate the clearance between self and the limit structure because of self gravity promptly, can paste with limit structure all the time and lean on the cooperation, limit structure can restrict the horizontal migration of whetstone simultaneously, avoid the whetstone to take place to remove the wearing and tearing lid because of the clearance when using, guarantee that the sharpener can be spacing to the stability of whetstone.

In the sharpener, the limiting structure comprises a limiting column protruding out of the inner bottom surface of the cover body and a groove formed in the sharpening stone, and the limiting column is embedded into the groove. The matching structure of the limiting column and the groove is simple, and the movement of the limiting column and the supporting part in the horizontal direction is restrained to a certain extent. The limiting structure can also be a limiting column arranged on the knife stone and a limiting column protruding out of the inner bottom surface of the cover body.

In the knife sharpener, a connecting structure for limiting the vertical position of the knife sharpening stone is further arranged between the inner bottom surface of the cover body and the knife sharpening stone. Through the design of the connecting structure, the movement between the knife stone and the cover body is further limited, the knife stone is prevented from colliding with the cover body or the base due to the self-displacement caused by external factors, and the stable limit of the knife stone in the cover body is ensured; and limit structure and connection structure separately set up, even when one of them structure can't be to the spacing of whetstone, another structure also can assist the whetstone remain stable on the box body, guarantees that the whetstone is stabilized spacing in the sharpener.

In the knife sharpener, the connecting structure comprises a glue dripping groove which is arranged on the inner bottom surface of the cover body and is used for filling glue, and the opening of the glue dripping groove is arranged upwards.

The connecting structure can also be a hook piece arranged on the inner bottom surface of the cover body and a connecting piece which is arranged on the knife stone and used for hooking the components into a ring shape.

In the knife sharpener, the inner bottom surface of the cover body is convexly provided with the supporting part for supporting the knife sharpening stone, and the limiting structure and the connecting structure are both arranged on the top surface of the supporting part. The limiting structure and the connecting structure are arranged on the supporting part, so that the distance between the two structures is shortened, the acting force of the limiting structure and the positioning structure for limiting the knife stone is more concentrated, the structure is more compact, and the two structures can limit the knife stone more stably; and the supporting part makes the interior bottom surface of whetstone and lid leave the space between, and the whetstone needs water to cool off cutter and whetstone when using, and this space can be used for storing waste water.

In the knife sharpener, a yielding gap is reserved between the outer side surface of the knife sharpening stone and the inner side surface of the cover body. The design in clearance of stepping down for the waste water of usefulness of whetting a knife can be followed the below that gets into the whetstone in the clearance of stepping down, realizes the water storage function, and the practicality is stronger.

In the knife sharpener, the inner bottom surface of the cover body is provided with the support piece which is arranged in a protruding mode, and the support piece is supported below the knife stone in an abutting mode. Through the design of a supporting piece, the supporting effect on the knife sharpening stone is increased, the knife sharpening stone is prevented from collapsing, and the stability of the knife sharpener in use is ensured.

In the knife sharpener, the outer side surface of the cover body is provided with the non-slip mat. Through the design of slipmat, increase whole sharpener's non-slip ability, increase sharpener in use's stability.

In the sharpener, the base is in a long strip shape, the base is detachably connected below the base, the upper surface of the base is provided with a concave working groove, a sharpener bar is arranged between the base and the base, one end of the sharpener bar is abutted against the base, and the other end of the sharpener bar penetrates through the working groove and is abutted against the base. This sharpener collects whetstone and whetstone in an organic whole, realizes the multi-functional of sharpener, with the whetstone setting between base and base, whetstone setting is on the lid for whetstone and whetstone can part and use simultaneously, increase this sharpener's practicality.

In foretell sharpener, the base is cubic, the upper surface of base has recessed constant head tank, the lower surface of base has recessed spacing groove, the slope of sharpener stick sets up, and the both ends of sharpener stick imbed constant head tank and spacing groove respectively, the outer peripheral face of sharpener stick supports with the cell wall of constant head tank and spacing groove respectively and leans on. Through foretell design for the knife sharpening stick can stably set up on base and base, guarantees that the cutter can stably polish on this sharpener.

Compared with the prior art, this sharpener has following advantage:

1. through leaning on limit structure and connection structure and supporting in the bottom of whetstone, effectively avoid the relative lid of whetstone to take place to shift, guarantee the stability of sharpener.

2. This sharpener collects the function in an organic whole of whetstone and whetstone stick to whetstone and whetstone stick can use simultaneously, and can not influence each other, this sharpener has stronger practicality.
