Description

Dimension measuring device

More particularly, the present invention relates to a dimension measuring apparatus, which measures the dimensions of various objects having an irregular three-dimensional shape easily and freely in an everyday life as well as an industrial site, ≪ / RTI >

Vernier calipers used for measuring dimensions such as length, width, and height generally have a main body 1 having a scale 1a formed on its outer side as shown in Fig. 1, (2) in which a main body (2a) is formed and slidingly moved along the outer side of the scale (1a) of the main body (1).

In this vernier caliper, a shoulder 1b and a shoulder 1c are fixed to a main body 1 of a quadrangle. The jaws 2b and 2c of the shoulder 2 are slidably moved along the main body 1 And measures the dimensions such as the inner diameter and outer diameter of the object.

However, the vernier caliper as described above measures the dimension in only one direction given by the dimension of the unidirectional direction, that is, the square main body 1 and the crown 2 coupled thereto, so that it is difficult to measure dimensions Is generated.

For example, in the case where the measurement object is irregular or not parallel, the measurement distance can not be measured because it is not formed in a straight line, and thus measurement can not be performed. In particular, an object having a different height, an object connected in a stepwise manner, a stepped object having irregularities, It becomes very difficult to measure the length.

From this, an octagonal caliper is proposed which can easily measure (move) an arbitrary angle without depending on the shape of the object to be measured, and to measure the dimensions of the object while rotating in one direction as well as the other direction and the vertical direction.

2A and 2B, the fixed jaw body 10 and the movable jaw body 20 are assembled and fixed to the fixed jaw body 10, as shown in Fig. 2A and Fig. 2B, A caliper for measuring the distance of a measured object (K) between a lip (11) and a moving jaw lip (22), characterized in that the fixed jaw body (10) has a regular octagonal cross section, A measurement graduation 13 is formed in the movable jaw body 20 and a rectangular recess 21 in which the fixed jaw body 10 is inserted is formed in the movable jaw body 20, And a measurement reference plate 24 having a through-hole 25 formed at the center thereof is fixed via bolts 23.

The conventional octagonal caliper configured as described above has a configuration in which the movable jaw body 20 is movable relative to the fixed jaw body 10 so as not to be separated from each other and the shape of the measured object is irregular, The movable jaw body 20 is pushed downwardly of the fixed jaw body 10 to be separated and then the angle is adjusted in accordance with the measurement point of the object to be measured so as to be engaged with the separating operation , It is possible to easily and precisely measure irregularly shaped objects to be measured, which were previously impossible to measure, by positioning them at the measurement points of the object to be measured.

However, in order to adjust the angle in accordance with the measurement position of the object to be measured, the conventional octagonal caliper has to separate the mobile jaw body 20 from the fixed jaw body 10 and adjust it to a desired angle, In particular, when the length of the object is continuously measured by varying the angle of the mobile jaw body 20, it is necessary to repeat the inconvenience of separation and engagement of the mobile jaw body 20 from the fixed jaw body 10, If the length of the measurement object is long, the inconvenience is added.

In addition, since the conventional octagonal caliper can be adjusted only by eight angles while being adjusted by 0 ° to 45 °, it is limited even when the angle is adjusted. Therefore, when the angle is out of the range, an error as much as the deviation occurs, Lt; / RTI >

In the conventional octagonal caliper, when the angle is adjusted, the angle to be adjusted is determined by observing the eye. Therefore, when the angle is adjusted not to be suitable for measuring the dimension of the object, accurate measurement is not performed or the movable jaw body 20, There is a disadvantage that it is necessary to separate and reassemble.

Accordingly, although it has been possible to measure the irregularly shaped object to be measured, which has not been possible in the past, all the troubles associated with it can not be avoided, and moreover, accurate measurement can not be ensured.

In addition, it is also necessary to make it easy to carry while measuring an object having a large dimension.
