Abstract

The invention discloses a glass cutter which comprises a cutter head (14) and a cutter bar (15), wherein the cutter head (14) is arranged at one end of the cutter bar (15), the glass cutter also comprises a backup plate, a ruler (12) and a sliding device, one end of the ruler (12) is fixedly connected to the backup plate in the vertical direction, the sliding device is connected with the ruler (12) in a sliding manner, and the cutter bar (15) is connected with the sliding device and is vertical to the plane of the ruler (12) close to the surface of glass. After the structure is adopted, the ruler is combined with the cutter head and the cutter bar, namely the cutter bar drives the cutter head to be matched with the ruler in a sliding way, so that a user can realize the function of marking on glass only by carrying one glass cutter; meanwhile, the vertical drawing board of the backup plate is abutted against the edge of the glass, so that a plurality of random parallel lines can be drawn, the operation is very convenient, and the parallelism is more accurate.

Description

Glass cutter

Technical field

The present invention relates to the parting tool technical field, specifically is a kind of glass cutter.

Background technology

Glass cutter refers to the cutter of glass-cutting, and the part that usually is used for cutting on the glass cutter is to be made by diamond or the alloy material larger than strength of glass.The glass cutter of prior art comprises cutter head and knife bar, and cutter head is fixed on the end of knife bar, and during operation, the user holds knife bar, and cutter head is got final product in delineation on glass.But there is following shortcoming in the glass cutter of this structure:

1) since glass when being cut, the necessary smooth and continuous of line, the glass section that cuts out so just can smooth rule, therefore, glass cutter need to be equipped with ruler when delineation or other scales are rule, so, the user must carry required ruler or other scales during operation, in case there are not these scale work just can not carry out;

2) when when glass surface is carried out the line of parallel lines or vertical line, with regard to as drawing on paper, need to several scale be operated simultaneously, such as, when drawing parallel lines, need two rulers, the first is worked as guiding ruler, second vertically resting on the first chi draws a line first, down or up moves along first chi again, draw again the second line after determining the position, therefore, this operation has two drawbacks: the one, operate cumbersome, the 2nd because the position of the more parallel lines that mark of human factor has deviation.

Summary of the invention

Technical problem to be solved by this invention is, accurately glass cutter of a kind of simple to operate, scribing position is provided.

For solving the problems of the technologies described above, glass cutter provided by the invention, comprise cutter head and knife bar, described cutter head is located at an end of knife bar, it also comprises backup plate, ruler and carriage, one end vertical direction of described ruler is fixedly connected on the backup plate, and carriage and ruler are slidingly connected, and knife bar is connected with carriage and perpendicular to the plane near glass surface of ruler.

Described backup plate is formed by connecting by top panel, lower panel, vertical panel and gusset plate, one end of described ruler is fixedly connected on the top panel, have two openings on the vertical panel, in two openings roller is installed all, the two ends of the central shaft of roller are connected with lower panel with top panel respectively, the outer circumference surface of roller protrudes from the plane of vertical panel, and the axis of each roller is all equal to the distance of vertical panel.

Described carriage comprises arbor support, knife bar seat and adjusting bolt, arbor support is slidingly connected on the ruler, the knife bar seat is connected to a side of arbor support, and adjusting bolt is threaded in the knife bar seat, and the lower end of adjusting bolt is connected with the upper end of knife bar.

Also has locking latches between described arbor support and the ruler, this locking latches comprises securing bolt and fixed block, fixed block is fixedly connected on the arbor support, and securing bolt is threaded in fixed block and the arbor support and the end face of securing bolt is pushed against on the ruler.

Described arbor support and ruler are slidingly connected and refer to, ruler relative both sides along its length all have groove, have the relative card base of both direction on the arbor support, and described two card bases are slidingly fitted in the groove respectively.

Described ruler edge in the longitudinal direction indicates scale.

Described ruler inside is hollow along its length.

After adopting above structure, the present invention compared with prior art has the following advantages:

1) because ruler and cutter head and knife bar are combined, namely knife bar band dynamic cutter head can be slidingly matched along ruler, and therefore, the user only need carry this glass cutter and just can be implemented in line function on glass;

2) simultaneously, end at ruler is connected with backup plate, like this, whole chi is just presented a T-shaped structure, utilize the vertical panel of backup plate to be resisted against the edge of glass, therefore, when whole glass cutter device moves up and down along the edge of glass or during move left and right, just can mark several random parallel lines, operation is very easy, and parallelism is also more accurate;

3) in backup plate, be provided with two rollers, and the outer circumference surface of roller protrudes from the plane of vertical panel, like this, backup plate is just by the outer circumference surface of two rollers and the edge contact of glass, make the whole mode of motion that rolls and cooperate that glass cutter and glass edge are, friction resistance is little, makes glass cutter more flexible with contacting of glass, and it is also more flexible to operate;

4) after being provided with locking latches between arbor support and the ruler, make carriage can be fixed on the ruler, that is to say, the position of cutter head is motionless, like this, when vertical panel slided along glass edge, cutter head just moved along the direction of sliding, therefore, can mark the groove perpendicular with the length direction of ruler;

5) between ruler and the arbor support by groove and card base cooperate realize sliding, make the slip of carriage on ruler more steady, simultaneously, this interface arrangment also avoids arbor support to drop out from ruler;

6) be provided with scale at ruler, can grasp clearer, intuitively the length of the bar of ruling when line user;

7) ruler is made the hollow structure of hollow, can be alleviated the weight of ruler, carry and use lighter.
