Abstract

The utility model provides a kitchen knife of removable blade, including cutter body, blade, its characterized in that: the cutter is characterized by further comprising a cutter frame, the lower portion of the cutter body and the upper portion of the blade are linear, the cutter frame is rectangular, the thickness of the upper portion of the cutter frame is consistent with that of the lower portion of the cutter body, a rectangular through hole is formed in the middle of the cutter frame from top to bottom, the width and the length of the through hole are matched with those of the blade, the blade is arranged in the through hole of the cutter frame to be connected in a matched mode, the upper end face of the blade is in contact with the lower end face. The blade is protected by the knife rest, so that the blade is not easy to deform, and the blade can be thinner, thereby greatly reducing the cost.

Description

The kitchen knife of changeable blade

Technical field

The utility model relates to a kind of kitchen knife of changeable blade.

Background technology

Usually, kitchen knife all is that cutter hub and blade are made of one, in order to reduce its cost, only add special material at knife edge part, but the rust of blade meeting in use for some time, need after whetting a knife, to be convenient to continue to use, after repeatedly whetting a knife, the special material of knife edge part can consume and lose, until ruing out of, this moment, kitchen knife have to be scrapped, and had brought unnecessary loss to the consumer virtually.Therefore, Chinese patent CN2294820Y discloses a kind of kitchen knife of replaceable blade, form by cutter hub and blade, bottom at cutter hub is provided with tongue and groove, the top of blade is provided with the emboss pit with cutter hub bottom tongue and groove form fit, emboss pit on the blade and the tongue and groove on the cutter hub are inlayed, and by the geometrical clamp of being located at the front and back end cutter hub and blade are fixed.The kitchen knife of this replaceable blade can not be done blade section thinner owing to be that blade is embedded on the cutter hub, is unfavorable for reducing cost significantly.

The utility model content

The utility model aims to provide the kitchen knife of the changeable blade that a kind of blade is thinner, cost is lower.

The technical scheme that the utility model adopted is: a kind of kitchen knife of changeable blade, comprise cutter hub, blade, it is characterized in that: also include knife rest, cutter hub bottom and blade top are linear, knife rest is rectangle, its top thickness is consistent with cutter hub bottom thickness, be provided with rectangular through holes from top to bottom in the centre, the width of its through hole, length and blade are suitable, blade is located at and is become to be connected in the through hole of knife rest and the upper surface contacts with the lower surface of cutter hub, and knife rest fuses by jockey and cutter hub.

Described jockey comprises cutter hub, knife rest, two ends in the cutter hub bottom respectively are provided with contiguous block, the centre is provided with manhole, thickness is less than the thickness of cutter hub, knife rest top offer groove, the width of groove matches with contiguous block thickness on the cutter hub, the contiguous block height on the depth ratio cutter hub is bigger, is provided with manhole on its two ends, lead to the hole site on the position of its through hole, size and the cutter hub, big or small consistent, connecting rod are arranged in the through hole on knife rest, the cutter hub.

The cutting edge of described blade can be arc.

The bottom of described cutter hub can also offer a groove, and its width, length match with the top of blade.

Described blade two ends can also be provided with limited block, and limited block places in the groove on knife rest top, and its size adapts with it.

The beneficial effects of the utility model are: (1) has protected blade owing to be built in knife rest, makes blade more not yielding, therefore, can do blade thinner, thereby reduce cost significantly; (2) because blade cutting edge is made as arc, guaranteed still can normally use when chopping board is recessed; (3) because a groove has been offered in the cutter hub bottom, matches with it in blade top, further improved the bulk strength of knife rest, blade, helped the thickness of attenuate cutter hub, reduced cost; (4) be provided with limited block at the blade two ends, and place in the groove on the knife rest, prevented from effectively to cause blade and knife rest poor fit to cause blade to break away from knife rest owing to repeatedly changing blade.

The specific embodiment

The structure of an embodiment of the utility model, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of kitchen knife of changeable blade comprises knife rest 2, blade 3, cutter hub 4.Cutter hub 4 bottoms are linear, and two ends respectively are provided with contiguous block 5, are provided with manhole in the middle of the contiguous block 5, and thickness is less than the thickness of cutter hub 4; Blade 3 is rectangle, and top is linear; Knife rest 2 is rectangle, its top thickness is consistent with cutter hub 4 bottom thickness, top offer groove, the width of groove matches with contiguous block 5 thickness on the cutter hub 4, contiguous block 5 on the depth ratio cutter hub 4 is highly bigger, on its two ends, be provided with manhole, the position of its through hole, the lead to the hole site of the contiguous block 5 on size and the cutter hub 4, size is consistent, in the middle of knife rest 5, be provided with rectangular through holes from top to bottom, the width of its through hole, length and blade 3 are suitable, the interior one-tenth of through hole that blade 3 is located at knife rest 2 is connected, and the upper surface contacts with the lower surface of cutter hub 4, be arranged in knife rest 2 by connecting rod 1, in the through hole on the cutter hub 4, they are fused, and connecting rod 1 can be a bolt, nut.

For guarantee chopping board through long-time use to cause still can normally use kitchen knife when recessed, therefore, blade 3 cutting edges are made as arc.

For further improving the bulk strength of knife rest 2, blade 3, more help the thickness of attenuate cutter hub 4, reduce cost, also offer a groove in the bottom of cutter hub 4, its width, length match with the top of blade 3.

For preventing to cause blade 3 and knife rest 2 poor fits to cause blade 3 to break away from knife rest 4 effectively owing to repeatedly changing blade 3, also be provided with limited block 6 at blade 3 two ends, limited block 6 places in the groove on knife rest 4 tops, and its size adapts with it.
