Description

A kind of board-like shrinking plate backer picture ruler

Technical field

The present invention relates to hand-held tool fields more particularly to a kind of board-like shrinking plate backer to draw ruler.

Background technique

Existing plate fitment requires to set up side shrinking plate or top once when being related to placing by wall or being installed to room top plate Shrinking plate, the reason is that place the ground or metope or top surface of furniture, unhorizontal not vertical or mutual out of plumb or not The corner angle staff or payment to a porter of flat shape and complicated surface, these are universal phenomena existing for existing structure, only pass through shrinking plate, The curve of peace scene variation is cut, and for correcting the deficiency of building, problem is that the prior art is by carpenter's craft Scribing line cutting after finite point measurement, first is that measurement point is limited, second is that hand dipping error is big, third is that spend more operation Time, this not only influences product quality, influences working efficiency, while influencing product beauty, and there are no be directed to this currently on the market The specific purpose tool of aspect, although the device that existing publication number is 2017206113375, workpiece is more, construction it is complicated and Heaviness, manufacturing cost is high, inconvenient to use, is unable to get fine popularization.

Summary of the invention

For above-mentioned background technique problem, one kind is invented for board-like shrinking plate backer and draws ruler, to facilitate site operation to draw Line uses.

The present invention is achieved by the following technical solutions.

A kind of board-like shrinking plate backer picture ruler, including scale and slide rule, the scale is square, wherein a right-angle side Equipped with the symmetrical shoulder in front and back, it vertically is equipped with concave slot with the shoulder in another right-angle side parallel direction, it is described One side opening of concave slot, opening outwardly, the slide rule is elongated, on a front of slide rule be equipped with groove, institute In the concave slot of the slide rule insertion the stated scale, and can slide up and down, and by the slide rule groove with it is described fixed The concave slot set on ruler is slidably matched and controls limit, and the left and right sides on the slide rule length direction is between being equipped with Every uniformly distributed aperture, wherein left side aperture and right side small hole center mutually stagger half spacing.

The concave slot set on the further scale can be set to "convex" shaped groove, correspondingly in the slide rule On a front be equipped with match therewith protrusion body.

It is symmetrical that the concave slot or "convex" shaped groove set on the further scale can be set as two sides, correspondingly exists Two sides is symmetrically arranged with the body of groove or protrusion on the slide rule.

Further technical solution is to cut the oblique angle of 10-45 degree at the slide rule both ends.

Further technical solution is that the spacing of two apertures takes 2mm, small aperture 1.2-1.5mm.

Present invention employs scales and slide rule, are slided on scale by slide rule, and pass through the concave slot on scale Cooperate with the groove set on slide rule, guarantees that slide rule is moved up and down without double swerve, 1.2- is taken by the aperture on slide rule 1.5mm guarantees that general bow pen microcephaly pen tip can penetrate positioning and draw lines, takes 2mm by two small pitchs of holes, and utilization is wherein left Between side aperture and right side small hole center mutually stagger half, as long as using in this way by slide rule rotary head, work can be made Precision reaches 1mm, it is sufficient to reach existing construction precision requirement, cut the oblique angle of 10-45 degree at slide rule both ends, to reduce slide rule shifting Dynamic to interfere with metope, component of the present invention is few, and delicate structure is easy to operate, easy to use, and setting-out is accurate, improves operation precision And efficiency.

Specific embodiment

Further explanation of the technical solution of the present invention with reference to the accompanying drawings and embodiments.

A kind of board-like shrinking plate backer picture ruler, including scale 1 and slide rule 2, the scale 1 is square, wherein always The arm of angle is equipped with the symmetrical shoulder 11 in front and back, is vertically equipped with concave slot with the shoulder in another right-angle side parallel direction 12,12 1 side opening of concave slot, outwardly, the slide rule 2 is elongated, on a front of slide rule 2 for opening Equipped with groove 21, the slide rule 2 is inserted into the concave slot 12 of the scale 1, and can be slided up and down, and by described The concave slot 12 set on slide rule groove 21 and the scale is slidably matched and left and right limits, 2 length direction of slide rule On the left and right sides along aperture 22 uniformly at intervals is equipped with, wherein left side aperture and right side small hole center 23 mutually stagger two points One of spacing.

The concave slot 12 set on the further scale 1 can be set to "convex" shaped groove, correspondingly described A front on slide rule is equipped with the body of the protrusion to match therewith.

It is symmetrical that the concave slot 12 or "convex" shaped groove set on the further scale 1 can be set as two sides, accordingly Ground two sides on the slide rule is symmetrically arranged with the body of groove or protrusion.

Further technical solution is to cut the oblique angle 24 of 10-45 degree at 2 both ends of slide rule.

It is below that the operation of the present embodiment field lofting further illustrates in conjunction with attached drawing 5.

Job step: one, first by rectangle shrinking plate 3 to be cut, pacifies field condition and horizontally or vertically leave actual installation Distance is simultaneously fixed temporarily placement, the shoulder of scale is abutted against on 3 edges of boards of shrinking plate to be cut, by the tip of slide rule against existing Profilogram 4 selectes the aperture on the slide rule of suitable spacing, can be turned around by slide rule using the precision of 1mm being obtained, by picture Pen tip passes through the aperture on selected slide rule, and two, scale is pushed, continuous setting-out is made.

It, can be by anti-a direction of scale when needing reversed draw.
