Description
Technical Field
The utility model relates to a square belongs to measuring tool technical field.
Background
The square is a tool with at least one right angle and two or more straight edges for scribing or testing the right angle, is a commonly used measuring tool in the work of checking and scribing, is used for detecting the perpendicularity of a workpiece and the perpendicularity of the relative position of the workpiece, is a professional measuring tool, is suitable for the perpendicularity test of machine tools, mechanical equipment and parts, is an important measuring tool in the mechanical industry for installation, processing and positioning and the like, and has the characteristics of high precision and good stability, but sometimes when the perpendicularity of the measured workpiece is measured, the corner is in fillet transition or a bulge is arranged on the measuring edge, two right-angled edges of the square cannot be tightly attached to the measuring edge of the measured workpiece, and the measuring precision of the perpe.
Disclosure of Invention
The utility model aims to solve the technical problem that a unfilled corner square is provided, its right angle is the unfilled corner design, has the protrusion for the fillet or be close to the measurement edge of corner if measure the corner of work piece, and the square's right-angle side still can paste tightly with measuring the limit, improves measurement accuracy, can solve prior art not enough.
The technical scheme of the utility model is that: a unfilled corner square comprises a right-angle triangular structure consisting of two right-angle sides and a bevel side, wherein the right angle is of a unfilled corner structure. If there is the protrusion for the fillet or the measurement edge that is close to the corner in the corner of measuring the work piece, because of the right angle is unfilled corner structure, consequently can avoid the fillet and have the protrusion with the measurement edge that is close to the corner, the right-angle side of square still can paste tight measurement with the measurement edge, improves measurement accuracy.
Further, the two right-angle sides are provided with straight sides which slide along the length direction of the corresponding right-angle sides. The straight edge slides along the right-angle edge and can flexibly avoid the bulge on the measuring edge of the workpiece, meanwhile, the straight edge is longer in length and can be attached to the measuring edge for a longer distance, and the measuring precision is further improved.
And further, the straight edges sliding along the length direction of the corresponding right-angle edge are connected to form a right-angle corner. When a workpiece without a bulge at a right-angle corner is measured, the two straight sides are connected in a sliding manner along the length direction of the corresponding right-angle side to form a right angle, so that a normal right-angle ruler is formed for measurement.
Further, length scales are arranged on the straight edges. The measurement can be performed.
Further, length scales are arranged on the bevel edge. The measurement can be performed.
An elastic clamping piece is arranged on one straight edge forming the right-angle corner, a clamping groove is formed in the elastic clamping piece, and a buckle matched with the clamping groove is arranged on the other straight edge. When the two straight sides are connected in a sliding mode along the length direction of the corresponding right-angle side to form a right angle, and a normal right-angle ruler is formed to be used, the clamping groove in the elastic clamping piece is clamped with the buckle, and the two straight sides are connected stably.
To sum up, the utility model provides a right angle edge is provided with the straight flange, and the straight flange is portable to be avoided in a flexible way the bellying on the measurement edge of measuring the work piece, has higher measurement accuracy's unfilled corner square.
Drawings
Fig. 1 and 4 are schematic structural views of the present invention;
fig. 2 and fig. 3 are usage status diagrams of the present invention.
Shown in the figure: a first right-angle side 1; a second right-angle side 2; a bevel edge 3; a first straight side 4; a second straight side 5; a first chute 6; a second chute 7; a workpiece 8; a fillet 9; a first protrusion 10; second protrusion 11, elastic card 12 and buckle 13.
Detailed Description
The embodiment of the utility model provides a: as shown in fig. 1 to 3, a unfilled corner square includes a right-angle triangular structure composed of a first right-angle side 1, a second right-angle side 2 and a hypotenuse 3, and the right angle is a unfilled corner structure. When there is the protrusion for fillet 9 or the measurement edge that is close to the corner if measure work piece 8's corner, because of the right angle be unfilled corner structure, consequently can avoid fillet 9 and have the protrusion on being close to the measurement edge of corner, the first right-angle side 1 and the second right-angle side 2 of square still can paste with the measurement edge of measuring work piece 8 and tightly measure, improve measurement accuracy.
The preferential first right-angle side 1 of this embodiment is provided with a first straight side 4 sliding along the length direction thereof, and the second right-angle side 2 is provided with a second straight side 5 sliding along the length direction thereof. The first straight edge 4 is provided with a first sliding groove 6, the second straight edge is provided with a second sliding groove 7, the first right-angle edge 1 and the second right-angle edge 2 are respectively provided with a sliding block which is correspondingly matched, both ends of the first sliding groove 6 and the second sliding groove 7 are of a sealing structure, the first straight edge 4 slides along the first right-angle edge 1 to avoid a first bulge 10 on one measuring edge of the workpiece 8, the second straight edge 5 slides along the second right-angle edge 2 to avoid a second bulge 11 on the other measuring edge of the workpiece 8, and meanwhile, the first straight edge 4 and the second straight edge 5 can be prevented from being separated from the corresponding right-angle edges when sliding, and the measuring accuracy can be further improved because the lengths of the first straight edge 4 and the second straight edge 5 are longer and can be closely attached to the measuring edges at a longer distance.
The first straight edge 4 and the second straight edge 5 preferred in this embodiment respectively slide along the length direction of the first right-angle edge 1 and the second right-angle edge 2, and the two are connected to form a right-angle corner. When the workpiece 8 without the bulge at the right-angle corner is measured, the first straight edge 4 and the second straight edge 5 form a right angle, and the normal square measurement is performed.
The preferred first straight edge 4 and second straight edge 5 of this embodiment are provided with length scales. The measurement can be performed.
The preferred bevel 3 of this embodiment is provided with length scales. The measurement can be performed.
In the preferred embodiment, as shown in fig. 4, the second straight edge 5 forming the right-angled corner is provided with an elastic card 12, the elastic card 12 is provided with a slot, and the first straight edge 4 is provided with a buckle 13 matching with the slot. When the first straight edge 4 and the second straight edge 5 are connected in a sliding mode along the length direction of the corresponding straight edge to form a right angle, and a normal square is formed to be used, the elastic clamping piece 12 of the second straight edge 5 bounces and resets again, the clamping groove is connected with the clamping buckle 13 in a clamping mode, the fixed phases of the two straight edges cannot slide again, a stable right-angle square is formed to be used, the elastic clamping piece 12 is broken off, the clamping groove is separated from the clamping buckle 13, and the two straight edges can slide again.
