Abstract

The present invention relates to a counter-sink washer capable of improving a loosening prevention function of a dish head bolt by adding a spring function to a counter washer washer,
A plate having a plate shape capable of accommodating the head portion of the plate head bolt, a central hole through which the bolt portion of the plate head bolt can be passed, and a cut portion connecting the center hole and the outside.

Description

Countersink washer

The present invention relates to a counter-sink washer, and more particularly, to a counter-sink washer capable of improving the unclamping function of a dish head bolt by adding a spring function to the counter-sink washer.

A bolt is used to assemble various objects or parts. When a bolt is used to assemble a part, a washer is used for the purpose of preventing the bolt from being tightened against the part and being loosened by vibration.

The above-mentioned washer is a mechanical part for use with a screw fastener such as a bolt and a nut to largely disperse the load applied to the bolt head or nut to prevent screw loosening or the like, and includes flat washer, square washer, spring washer, / External washer, band washer, wave washer, insulation washer, rubber washer, turtle washer, countersink washer and special washer.

The countersunk washer described above is used with a dish head bolt.

1 is a view showing a state of use of a conventional counter-sink washer.

1, the conventional countersunk washer 3 is installed and assembled between the hole 1a of the object 1 and the dish head bolt 2 so that the load of the dish head bolt 2 It serves to disperse and prevent loosening.

However, the above-described conventional counter-sink washer has a problem that the anti-loosening function of the dish head bolt is relatively weak.

SUMMARY OF THE INVENTION An object of the present invention is to provide a countersunk washer capable of improving a loosening prevention function of a dish head bolt by adding a spring function to a countersunk washer.

In order to achieve the above-mentioned object, the present invention is characterized in that the structure of the present invention has a plate shape in which a head portion of a plate head bolt can be housed, a central hole through which a bolt portion of a plate head bolt can pass, It is preferable that a cut portion connecting the outside is formed.

The construction of the present invention is preferably such that one end of the cut portion of the countersink washer is positioned above the other end.

It is preferable that the folding line is formed on the opposite side of the cutting portion with respect to the center hole of the counter-sink washer.

The present invention has the effect of improving the loosening preventing function of the dish head bolt by adding the spring function to the counter sink washer.

1 is a view showing a state of use of a conventional counter-sink washer.
2 is a perspective view of a countersunk washer according to an embodiment of the present invention.
3 is a view illustrating a state of use of the counter sink washer according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention. Other objects, features, and operational advantages, including the purpose, operation, and effect of the present invention will become more apparent from the description of the preferred embodiments.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory only and are not to be construed as limiting the scope of the invention as disclosed in the accompanying claims. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and similarities, many of which are within the scope of the present invention.

Also, terms and words used in the description and claims of the present invention are defined based on the principle that the inventor can properly define the concept of a term in order to explain its invention in the best way, And should not be construed as limited to only the prior art, and should be construed in a meaning and concept consistent with the technical idea of the present invention. For example, the terms relating to directions are set on the basis of the position represented on the drawing for convenience of explanation.

FIG. 2 is a perspective view of a counter-sink washer according to an embodiment of the present invention, and FIG. 3 is a view illustrating a state of use of the counter-sink washer according to an embodiment of the present invention.

As shown in Figs. 2 and 3, the configuration of the counter sink washer 4 has a plate shape capable of accommodating the head portion of the plate head bolt 2, and the bolt portion of the plate head bolt 2 And a cutting portion 4b connecting the center hole 4a to the outside is formed in the center hole 4a.

The cut portion 4b of the counter-sink washer 4 has a structure in which one end is located at the upper portion or the lower portion of the other end.

A folding line is formed on the opposite side of the cutting portion 4b with respect to the center hole 4a of the counter-sink washer 4. [

The operation of the counter sink washer according to the above-described configuration is as follows.

After the countersink washer 4 is assembled and engaged between the hole of the object 1 and the dish head bolt 2 and then an impact or vibration is applied to the object 1 and the dish head bolt 2, 4) to prevent the plate head bolt (2) from being broken by impact or vibration.

In addition, the cutting portion 4b of the counter-sink washer 4 has an elastic force like a spring because one end of the cutting portion 4b is positioned at an upper portion or a lower portion of the other end than the other end, thereby preventing the plate head bolt 2 from being loosened Thereby preventing loosening as a result.

1: object 2: plate head bolt
3, 4: Countersink washers
