Description

[0001] BOLT MEASURING DEVICE [0002]

The present invention relates to a device for measuring the thickness and length of a bolt.

A bolt is a mechanical element used to fix building materials or machine parts, usually with a head, which is threaded into a round bar. The shape of the head is usually hexagonal, but there are also squares, cylinders, and saucers. The most widely used is through bolts, bolts in the holes of the bolts, and then tighten with a nut.

Bolts are usually made of steel and are called bolts, semi-finished bolts, black bolts, etc., which are finished according to the fineness of the surface. There are also bolts made of brass or light alloy.

The load applied to the threaded portion of the bolt may be subjected to axial load, torsion, shear load, axial load, or static load.

These bolts are used in various lengths and types in the assembly process of the product and are generally used after being classified according to their length.

Therefore, it is desirable to measure the length and thickness of the mixed bolts, classify them according to length and thickness, and store and manage them. The present invention is intended to easily measure the length of the bolt.

There is an open utility model 2015-0001739 to measure the length of the bolt. However, this is different from the measurement of a stud bolt measuring device, which is different from the measurement of a common bolt having a bolt head as in the present invention.

The present invention aims to easily measure and separate the thickness and length of various bolts.

The present invention provides a body 30, 430 formed of a hole or groove processable material); Bolt insertion holes or grooves (10a, 410a; 10b, 410b) formed in the body; And a scale (20, 410aa) formed in the body in parallel with the bolt insertion hole or groove adjacent to the bolt insertion hole or groove, and the bolt (200, 300) can be inserted into the bolt insertion hole or groove, And the length of the bolt can be measured by the scale.

Also, in the present invention, the bolt insertion hole or groove may be formed from the upper surface to the bottom surface of the body.

In the present invention, the bottom surface of the bolt insertion hole may have a recess 11 formed therein.

Also, in the present invention, the bolt insertion hole or groove is formed in accordance with the standard of the bolt thickness, and the thickness of the bolt to be inserted can be measured.

Further, in the present invention, when the bolt measuring device is for measuring the length of the plate head bolt, the head of the plate head bolt may be inserted into the bolt insertion hole or the groove, The bolt insertion hole or the end of the groove may be formed so as to stop the head of the bolt.

The present invention has a hole or groove through which a bolt can be inserted into the body and a ruler is engraved on the body so that the bolt can be easily inserted into the hole or groove so that the length of the bolt can be easily measured.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Fig. 1 shows that the bolt 200 to be measured in the present invention is inserted into the bolt insertion hole 10a of the measuring apparatus 100 of the present invention.

The measurement apparatus 100 of the present invention comprises a body 30 capable of hole processing and a bolt insertion hole 10a is formed in the body 30 so that the bolt 200 can be inserted.

A scale 20 is formed on the body 30 adjacent to the bolt insertion hole 10a to measure the length of the inserted bolt.

Further, the bolt insertion hole 10a is formed to fit the thickness of the bolt to be inserted, so that the thickness of the bolt to be inserted can also be measured.

2A shows a bolt insertion hole 10a and a scale 20 passing through a body 30, a top surface to a bottom surface of the body in a state where the bolt 200 is separated from the measuring apparatus 100. FIG.

It is preferable that the bolt insertion hole 10a penetrate to the bottom surface and the bottom surface has a recess 11 that is wider than the diameter of the insertion hole so that the bolt insertion hole 10a can be wiped with the cleaning rod when foreign substances are present in the bolt insertion hole 10a Do.

FIG. 3A is a plan view of FIG. 2, in which a bolt insertion hole 10a is formed in the center of an upper surface, and the cross section is circular.

FIGS. 2B and 3B show the bolt insertion holes 10a of FIGS. 2A and 3B in the form of bolt insertion grooves 10b.

The bolt insertion grooves 10b of FIGS. 2b and 3b are not formed in the body as shown in FIG. 3a but are formed in the form of a groove 10b formed on one side of the body in the vertical direction of the body, ), The bolt length can be measured.

Figs. 3C to 3E are examples in which the cross-sectional shape of the bolt insertion hole 10b in Fig. 3B is modified, and Figs. 3F and 3G are examples in which the cross section of the bolt insertion hole 10a is modified.

The bolt insertion hole 10a and the groove 10b are preferably circular in cross section, but are not limited thereto and can be modified into various shapes.

In FIG. 3F, the body is divided into two portions 30a and 30b. After the bolts are inserted into the holes 10f, the body is detached and the bolt length can be measured.

In FIGS. 3A, 3F, and 3G, all the length portions of the bolt are inserted into the body. In FIGS. 3B to 3E, only a part of the length portion is inserted into the insertion grooves 10c, 10d, 10e, and 10g formed in the body.

Fig. 4 is a measuring apparatus 400 capable of measuring the length of the dish head bolt 300 of Fig. 7 according to another embodiment of the present invention.

The dish head 310 is inserted into an upper portion of the bolt insertion hole 410a of the measuring apparatus 400. [

Since the head is not fastened in the case of the conventional bolt 200 but is fastened to the head end in the head bolt 300, the length of the screw is measured from the end of the head. The bolt insertion hole 410a of the measuring device 400, So that the dish head 310 can be inserted.

FIG. 5A is a plan view of the measuring apparatus 400 of FIG. 4, FIG. 6 shows a plain bolt 200, and FIG. 7 shows a dish head bolt 300.

FIGS. 5B to 5E are views showing the bolt insertion hole 410a being deformed into the bolt insertion groove, as shown in FIGS. 3B to 3E. FIG. 5F is a hole having an elliptical shape in cross section and FIG. 5F is a hole having a rectangular shape in cross section.

5b to 5e are formed with bolt insertion grooves 410b, 410c, 410d and 410e on one side of the body 430 and FIGS. 5a, 5f and 5g are bolt insertion holes 410a, 410f and 410g, (Not shown).

5A, 5F, and 5G, the plate head bolt has a structure in which the entire length of the bolt is inserted into the body 430, and in FIGS. 5B to 5E, a part of the length of the bolt is placed in the groove.

As described above, in the present invention, the bolt insertion hole or groove is formed in the measuring apparatuses 100 and 400 and the bolt is inserted into the bolt insertion hole or groove, and then the thickness and length of the bolt can be measured. have.

In the case of the bolt insertion hole, it is preferable that the bolt insertion hole is formed of a transparent material such as acrylic. However, when the bolt insertion hole is formed in the shape of a groove, the bolt insertion hole can be replaced with all materials such as opaque plastic and machinable aluminum.

For reference, bolts are standardized by thickness and length.

The thickness (diameter) is generally 2, 3, 4, 5, 6, 8, 10a, 12, 16, 20mm, and the length is more than the thickness.

For example, bolt M5x10a refers to a bolt with a thickness of 5 mm and a length of 10 am.

This device enables simultaneous measurement of the thickness and length of the bolt.

The diameter of the hole or groove of the device is formed to be slightly larger than the thickness of the bolt, so that the bolt is easily inserted and formed to match the thickness.

For example, a bolt of M5x10a is made slightly larger than 5mm so that bolts with a diameter of 5mm can be inserted easily.
