Abstract
The utility model relates to a can opener with a roll cutter, which is a household commodity used for opening metal cans and wavily cutting metal containers such as paint barrels, coal oil barrels, etc. When the metal skins on the upper part of the cans and barrels are pressed by the utility model, a ratchet wheel is rotated by hand to drive the cutter to wavily cut to open the metal cans and barrels. The utility model is provided with a cutter seat board and a ratchet wheel seat board which is rotationally connected with the cutter seat board by connecting pieces; the spherical protrusion of the cutter seat board is provided with the mounting hole of a declivitous cutter shaft which is fixed on the cutter seat board through an inclined hole; the exposing end of the cutter shaft is provided and is rotationally connected with the cutter; the ratchet wheel seat board is provided with the mounting hole of a ratchet wheel shaft which is rotationally connected with the ratchet wheel seat board through the mounting hole; the ratchet wheel shaft is fixedly connected with the ratchet wheel and a ratchet wheel handle fixedly connected by screw thread.
Description
The utility model is a kind of family daily necessity of manually opened metal can, also can be used for cans such as scroll-diced paint kettle, kerosene bucket.This instrument rotates ratchet with hand when the metal skin on jar bucket top is exerted pressure, drives the cutting knife scroll-diced, to reach the purpose of opening metal jar bucket.
The instrument of the unlatching iron sheet can of selling on the market is a kind of crush-cutting formula metal can opener at present.This instrument utilizes lever principle, with its blade tip to applying static pressure above the can, to reach the purpose of opening can.But because this instrument mechanical efficiency is low, cutting power is poor, thereby the operation effort, damages easily, and service life is short, and kerf quality is low.
The purpose of this utility model is to provide a kind of roll-turning metal can opener, by the ratchet hand feed, and the cutting knife scroll-diced, not only easy and simple to handle, laborsaving saving time, and long service life, kerf quality is good.
The technical scheme and the substance of the roll-turning metal can opener that the utility model proposes are: the ratchet seat board that this opener has a cutting knife seat board and is rotationally connected with attaching parts and cutting knife seat board, a downward-sloping slitter shaft mounting hole is arranged on the ball bumps of cutting knife seat board, slitter shaft is fixed on the cutting knife seat board by inclined hole, one cutting knife that is rotationally connected is housed on the slitter shaft bared end, a ratchet shaft mounting hole is arranged on the ratchet seat board, ratchet shaft is rotationally connected by this hole and ratchet seat board, and the ratchet of captive joint and the ratchet handle of captiveing joint with screw thread are arranged on the ratchet shaft.The user with the right hand hold cutting knife seat board and pawl seat wrench handle make cutting knife and ratchet near and clamping after on the metal can, with the right hand rotating ratchet handle ratchet rolling below the metal can upper end flange is advanced, the effect lower cutter of friction force rotate and with blade cutting metal jar on the plane, thereby reach a purpose of opening jar barrel.
In sum, the utility model is compared with prior art, has following characteristics, advantage and good effect:
The utility model is owing to adopt the ratchet hand feed, and the cutting knife continuous rolling cuts, the mechanical efficiency height, and cutting power is strong, saves manpower and time, and is easy to operation.
The utility model is because the cutting knife heat treatment hardness reaches HRC50～65, and the ratchet heat treatment hardness reaches HRC40～55, and is not fragile, long service life.
The utility model is located owing to bending protuberance with the Zhe on the ratchet seat board, energy continuous feed when guaranteeing that by the ratchet rotation cutting knife cuts, and kerf quality is good.
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation according to the roll-turning metal can opener that the utility model proposes.
Fig. 2 is the A-A section-drawing of roll-turning metal can opener.
Fig. 3 is the cutting knife detail drawing of roll-turning metal can opener.
Fig. 4 is the ratchet detail drawing of roll-turning metal can opener.
Describe realization concrete structure of the present utility model, best way and service condition in detail below in conjunction with accompanying drawing.
Roll-turning metal can opener is assembled by ratchet seat board (1), cutting knife seat board (2), ratchet handle (3), cutting knife (4), ratchet (5), ratchet shaft (6), slitter shaft (7), ladder rivet shaft (8), taper knob (9).Above part at first is assembled into pawl seat board component and Cutter apron board component, with two ladder rivet shafts it is assembled into integral body again.
The pawl seat board component is made up of ratchet seat board (1), ratchet handle (3), ratchet (5), ratchet shaft (6).The shank of ratchet seat board is equipped with taper knob (9).Ratchet shaft (6) and ratchet handle (3) are with being weldingly connected.Ratchet (5) and ratchet shaft (6) are with being threaded.During with hand rotating ratchet handle (3), sour jujube commentaries on classics (5) seat board (1) relatively rotates freely.
The Cutter apron board component mainly is made up of cutting knife seat board (2), cutting knife (4), slitter shaft (7).The shank of cutting knife seat board is equipped with taper knob (9).The small end of slitter shaft (7) links to each other with cutting knife seat board (2) with welding.Cutting knife (4) slitter shaft (7) relatively rotates freely.
After pawl seat board component and Cutter apron board component fit together with two ladder rivet shafts (8), just can be that the center relatively rotates with the ladder rivet shaft on right side.The user grasps the handle of two seat boards, can adjust the distance between cutting knife (4) and the ratchet (5) effectively, make its easily clamping on metal can.
When withstand with the ratchet on ratchet (5) cylindrical metal can upper end flange below after, again the blade of cutting knife (4) is pushed down the last plane of metal can, and is propped up the cylinder of metal can with the curved protuberance of the Zhe of ratchet seat board (1), make it keep good location.The user uses right hand clockwise direction rotating ratchet handle (3) simultaneously with left hand grip pressure two seat board handles effectively, and ratchet (5) is rotated.Under the effect of friction force, cutting knife (4) rotates and advances and the scroll-diced metal skin, opens jar purpose of bucket thereby reach.
For describing best way of the present utility model in detail, existing vital parts to roll-turning metal can opener further is explained as follows:
As shown in Figures 1 and 2, ratchet seat board ［ 1 ］ is formed by the steel plate punch process.One ratchet shaft mounting hole is arranged in the middle, and there is a connection piece mounting hole on the right side, and there is a waist shape elongated slot in the left side, so that ratchet seat board ［ 1 ］ can rotate in waist shape interval.Have a Zhe to bend protuberance below the ratchet seat board, the location is used when opening jar.
As shown in Figures 1 and 2, cutting knife seat board ［ 2 ］ is formed by the steel plate punch process.One ball bumps is arranged in the middle.One downward-sloping 20～30 ° slitter shaft mounting hole is arranged on the ball bumps.In the ball bumps both sides a connection piece mounting hole is arranged respectively.
As shown in Figure 3, cutting knife (4) is processed by carbon tool steel or alloy tool steel, and after heat treatment hardness reaches HRC50～65.Its tool point angle A is 40～60 °.
As shown in Figure 4, ratchet (5) is processed by structural carbon steel or alloy structureal steel, and after heat treatment hardness reaches HRC40～55.Its anterior angle B is one 25～-30 °, and its tooth angle C is 75～80 °.
