Description

Technical Field

[0001] The utility model relates to the technical field of ceramic measurement, in particular to a special ruler for measuring the shape of ceramics. Background Art

[0002] Ceramics are generally made of natural clay and a variety of natural minerals as the main raw materials, which are crushed, mixed, formed and calcined to form ceramic utensils with a certain shape. The specifications and sizes of ceramics are different, and the blank forming process is also different; ceramics can be obtained into a predetermined shape through blank forming, firing and cooling.

[0003] For small round ceramics with relatively simple shapes, the maximum diameter, minimum diameter and height can be measured by general rulers such as vernier calipers or steel rulers. Some larger ancient ceramics or antique ceramics have a protruding bell-shaped mouth on the top, with a slender neck below the bell-shaped mouth and a bulging belly below the slender neck, which exceeds the measuring range of common vernier calipers. Steel rulers or tape measures cannot be used to accurately measure the diameter, maximum diameter and other external dimensions of the ceramics, and it is difficult to measure the diameter of the bulging belly using general rulers.

[0004] In addition, when using a universal ruler to measure the external shape of relatively simple ceramics or ancient ceramics, the vernier caliper or steel ruler needs to be held continuously with one or both hands, and metal products are sharp and rigid, which can easily damage ceramics and fail to protect them. If an accident occurs, the ceramics or relatively precious ancient ceramics will be knocked over, which will be an immeasurable loss. Therefore, the problem that technicians in this field need to solve is to provide a special ruler for measuring the external shape and size of ceramics, which is convenient for measuring the external shape and size of ceramics, has high ceramic size measurement efficiency, and protects ceramics.

[0042] A first transverse ruler 3 is slidably connected on the surface of the first longitudinal ruler 1 and the second longitudinal ruler 2; a first lifting eye screw 7 is pierced through the first longitudinal slider 14, and the first lifting eye screw 7 passes through the through hole at the side end of the first transverse ruler 3, and the first lifting eye screw 7 fastens the first transverse ruler 3 at a specified height; the second longitudinal slider 16 is arranged at the bottom end of the second longitudinal slide groove 15, and a second lifting eye screw 8 is pierced through the second longitudinal slider 16, and the second lifting eye screw 8 is threadedly connected to the second longitudinal slider 16, and the second lifting eye screw 8 passes through the second longitudinal slide groove 15 and the first transverse slide groove 12 respectively, and is fixed on the surface of the first transverse ruler 3.

[0043] The second lifting ring screw 8 cooperates with the first lifting ring screw 7 so that the first transverse ruler 3 slides longitudinally along the first longitudinal ruler 1; specifically, the first lifting ring screw 7 and the second lifting ring screw 8 are loosened at the same time, and the first transverse ruler 3 is lifted upward or pulled downward so that the first transverse ruler 3 slides back and forth along the first longitudinal ruler 1, so as to place the first transverse ruler 3 on the top end face of the ceramic to measure the height dimension of the ceramic.

[0044] Or, the second lifting screw 8 slides laterally along the first transverse slot 12 to adjust the distance between the first longitudinal ruler 1 and the second longitudinal ruler 2, referring to Figure 3 Specifically, tighten the first lifting ring screw 7 and loosen the second lifting ring screw 8 at the same time, and slide the second longitudinal ruler 2 horizontally back and forth along the first transverse slide groove 12 to adjust the distance between the first longitudinal ruler 1 and the second longitudinal ruler 2, so as to facilitate the measurement of the maximum diameter of the ceramic and efficiently measure the external dimensions of the ceramic.

The 0 scale of the first transverse ruler 3 is flush with the inner side edge of the first longitudinal ruler 1, and the inner side edge refers to the edge that abuts against the maximum diameter of the ceramic when measuring the outer dimensions of the ceramic. The first transverse ruler 3 overlaps the top of the ceramic, and the first longitudinal ruler 1 and the second longitudinal ruler 2 respectively abut against the two arc surfaces in the diameter direction of the ceramic to detect the maximum diameter of the ceramic, which is convenient and fast, and the outer dimensions of the ceramic are measured efficiently.

[0046] A first transverse groove 12 is provided on the first transverse ruler 3, and the first transverse groove 12 is configured as a waist-shaped groove. A second lifting eye screw 8 is passed through the first transverse groove 12, and the second lifting eye screw 8 is also penetrated by the second longitudinal groove 15, and is threadedly connected with a second longitudinal slider 16 provided below the second longitudinal groove 15, so that the second longitudinal ruler 2 can slide horizontally along the first transverse ruler 3, or the first transverse ruler 3 can slide vertically along the first longitudinal ruler 1 and the second longitudinal ruler 2.

[0047] Preferably, a level installation slot is provided above the first horizontal ruler 3, and a level 5 is installed in the level installation slot. Figures 1 to 3Overlap the first horizontal ruler 3 on the top of the ceramic, observe the bubble position of the bubble tube of the spirit level, and you can see whether the first horizontal ruler 3 is horizontal.

[0051] Specifically, the second transverse ruler 4 is made of 5 mm stainless steel round rod. Figure 7 and Figure 8 The thinner diameter is conducive to the end face of the second transverse ruler 4 to abut against the shape of the ceramic, which is convenient for accurately measuring the outer dimensions of the bulge of the ceramic.

[0052] The second transverse ruler 4 is inserted into the aperture of the second transverse ruler sliding block 13, and the second transverse ruler 4 slides horizontally along the second transverse ruler sliding block 13.

The brush 18 can be a pencil, a ballpoint pen, a marker or a watercolor pen to copy the outline of the ceramic; in this specific embodiment, the brush 18 is a carbon lead. Before copying the outline of the ceramic, the carbon lead is asymmetrically cut so that the tip of the carbon lead is located on the side that fits the ceramic, so that the outline of the ceramic is copied more accurately. Specifically, a pen cap is fixed at the end of the second transverse ruler 4, and the pen cap is configured to be formed by bending an annular hard plastic arc. The bottom end of the pen cap is adapted to the arc radius of the second transverse ruler 4, and the pen cap fits the ceramic.

[0056] The first longitudinal ruler 1 and the second longitudinal ruler 2 are configured to be made of long strips of bakelite, which have high mechanical strength and good insulation properties. Bakelite is actually a thermosetting phenolic plastic product, which is less likely to knock against the surface of ceramics than metal products such as stainless steel, thereby protecting ceramics. This is of great significance for the measurement of larger cultural relics such as ancient ceramics.

[0057] A base 10 is provided below the longitudinal ruler. Figure 6 , the base 10 is provided with a snap-in groove, and the longitudinal ruler is snap-into the snap-in groove; specifically, a base 10 is provided below the first longitudinal ruler 1 and the second longitudinal ruler 2, and the base 10 is provided with a snap-in groove, and the snap-in groove abuts against the side edges of the first longitudinal ruler 1 and the second longitudinal ruler 2 to improve the stability of the special ruler for measuring the shape of ceramics, reduce the probability of the special ruler for measuring the shape of ceramics tilting and falling and bumping against the ceramics, and protect the ceramics to avoid damage to the ceramics.
