Description

本考案は、角座金に関し、特に、構造強度が高い角座金に関する。 The present invention relates to a square washer, and more particularly to a square washer having high structural strength.

従来、日常生活ではビスを利用して被螺着体を位置決めしたり、固定したり、調整したり、接続したりすることが一般的である。ビスを螺着する際、ビス頭部が被螺着体に力を加える面積を増やすために、ビス頭部と被螺着体との間に座金を配設し、ビス頭部と被螺着物との間の固定面積を増大させて受ける力を分散させることにより、被螺着体の表面を保護し、被螺着体の表面においてビス頭部が回転して被螺着体が損壊してしまうことを防ぐ。   Conventionally, in a daily life, it is common to position, fix, adjust, and connect a screwed object using a screw. When screwing a screw, in order to increase the area in which the screw head applies force to the screwed body, a washer is provided between the screw head and the screwed body, and the screw head and the screwed object The surface to be screwed is protected by increasing the fixed area between the screw and the screw, and the screw head rotates on the surface of the screw to be damaged. To prevent it.

従来の座金は平坦な板体で構成されている上、ビスを挿通させる穿孔がその中央に形成され、穿孔の直径がビス頭部の直径より小さく設計されている。実際に使用する際、ビスは、穿孔に挿通されてから被螺着体上に螺着されるため、ビス頭部を回転させてビスを螺着する際、座金に形成された穿孔の周囲が、ビス頭部が押し付けられた圧力を受け、座金に形成された穿孔の周囲の構造強度が不足することにより、座金の穿孔の周囲がビス頭部から印加される大きめの圧力に耐えることができずに、座金の中央が凹んで周囲が反り上がってしまい、最悪の場合、座金が破壊され、ビス頭部と被螺着体との間の固定面積を座金により増大させることができなくなる虞があった。   A conventional washer is composed of a flat plate body, and a perforation through which a screw is inserted is formed at the center, and the diameter of the perforation is designed to be smaller than the diameter of the screw head. In actual use, the screw is inserted into the hole and then screwed onto the member to be screwed. Therefore, when the screw is screwed by rotating the screw head, the periphery of the hole formed in the washer is Because of the insufficient pressure of the structure around the perforations formed in the washer due to the pressure applied to the head of the screw, the periphery of the perforation of the washer can withstand the large pressure applied from the screw head. In the worst case, the washer may be destroyed and the fixed area between the screw head and the member to be screwed may not be increased by the washer. there were.

そのため、従来の座金構造の強度を高める角座金が求められていた。   Therefore, there has been a demand for a square washer that increases the strength of the conventional washer structure.

本考案の目的は、構造強度が高い角座金を提供することにある。 An object of the present invention is to provide a square washer having high structural strength.

上記課題を解決するために、本考案の第１の形態によれば、板体、複数のリブ及び複数の凹溝を備える角座金であって、前記板体は、第１の表面及び第２の表面を有し、穿孔が中央に形成され、前記リブは、前記板体の周縁に向かって延びるように、前記第２の表面に形成され、前記凹溝は、前記リブと表裏の関係になるように前記第１の表面に形成されていることを特徴とする角座金が提供される。 In order to solve the above problems, according to a first embodiment of the present invention, a square washer comprising a plate body, a plurality of ribs and a plurality of concave grooves, the plate body comprising a first surface and a second surface. The rib is formed in the second surface so as to extend toward the periphery of the plate body, and the concave groove is in a relationship between the rib and the front and back surfaces. A square washer is provided on the first surface.

前記リブは、４つの直線リブを含み、前記直線リブには、前記穿孔に隣接した箇所から前記板体の周縁に向かって対称的に延設され、前記直線リブが前記穿孔を中心として十字状に形成されていることが好ましい。   The rib includes four straight ribs, and the straight ribs are symmetrically extended from a position adjacent to the perforations toward the periphery of the plate body, and the straight ribs are cruciform around the perforations. It is preferable to be formed.

前記リブは、前記穿孔を取り囲むようにその周囲に設けられた環状リブを含み、前記直線リブは、前記環状リブの外側に接続され、前記板体の周縁に向かって対称的に延設されていることが好ましい。   The rib includes an annular rib provided around the perforation so as to surround the perforation, and the linear rib is connected to the outside of the annular rib and extends symmetrically toward the periphery of the plate body. Preferably it is.

前記板体は、矩形状であり、前記第２の表面に向かって僅かに折り曲げられた折り曲げ部を四隅にそれぞれ有することが好ましい。   It is preferable that the plate has a rectangular shape and has bent portions slightly bent toward the second surface at the four corners.

本考案の角座金は、板体上に形成した複数のリブ及び複数の凹溝により全体の構造強度を高め、ビスにより角座金を被螺着体上に固定させるため、角座金が変形することを防ぎ、角座金と被螺着体との間の接触面積及び保持力を高めることができる。 The square washer of the present invention has a plurality of ribs and a plurality of concave grooves formed on the plate body to increase the overall structural strength, and the square washer is fixed on the screwed body with screws, so that the square washer is deformed.

以下、本考案の実施形態について図に基づいて説明する。なお、これによって本考案が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited thereby.

（第１実施形態）
図１及び図２を参照する。図１は、本考案の第１実施形態に係る角座金を示す正面斜視図である。図２は、本考案の第１実施形態に係る角座金を示す背面斜視図である。図１及び図２に示すように、本考案の第１実施形態に係る角座金１０は、板体１１、複数のリブ１３及び複数の凹溝１５から構成されてなる。 (First embodiment)
Please refer to FIG. 1 and FIG. FIG. 1 is a front perspective view showing a square washer according to a first embodiment of the present invention. FIG. 2 is a rear perspective view showing the square washer according to the first embodiment of the present invention. As shown in FIGS. 1 and 2, the square washer 10 according to the first embodiment of the present invention includes a plate body 11, a plurality of ribs 13, and a plurality of concave grooves 15.

板体１１は、第１の表面１１１及び第２の表面１１２を含む。板体１１には、ビスの軸（図示せず）を挿通させる穿孔１１３が中央に形成されている。   The plate body 11 includes a first surface 111 and a second surface 112. A perforation 113 through which a screw shaft (not shown) is inserted is formed in the plate 11 at the center.

複数のリブ１３は、板体１１の周縁に向かって延びるように、第２の表面１１２に形成されている。   The plurality of ribs 13 are formed on the second surface 112 so as to extend toward the periphery of the plate body 11.

複数の凹溝１５は、リブ１３と表裏の関係になるように第１の表面１１１に形成されている。複数の凹溝１５は、第２の表面１１２のリブ１３と表裏の関係になるように第１の表面１１１に形成されている。   The plurality of concave grooves 15 are formed on the first surface 111 so as to have a front-back relationship with the ribs 13. The plurality of concave grooves 15 are formed on the first surface 111 so as to have a front-back relationship with the ribs 13 of the second surface 112.

図３及び図４を参照する。図３及び図４に示すように、実際に使用する際、まず、ビス２０の頭部２２下方にスプリングワッシャ−４０を配設してから、ビス２０の軸２１を穿孔１１３へ挿通させ、被螺着体３０のビス孔３１に位置合わせしてから、ビス２０の頭部２２を回転させて軸２１をビス孔３１へ螺着させる。このとき角座金１０は、頭部２２と被螺着体３０との間に位置し、リブ１３は、被螺着体３０の表面に当接される。頭部２２は、スプリングワッシャ−４０を介して第１の表面１１１に当接され、これら複数のリブ１３の一部が頭部２２と被螺着体３０との間に位置して頭部２２を支え、スプリングワッシャ−４０を介して板体１１に圧力を印加する。複数のリブ１３は、角座金１０の構造強度を高め、穿孔１１３の周囲により頭部２２が印加する圧力に耐えることができる。また、複数のリブ１３及び複数の凹溝１５は、角座金１０の中央から周囲に向かって延び、頭部２２から角座金１０に印加される圧力を分散させ、穿孔１１３の周囲に応力が集中しないため、角座金１０が変形して損壊することを防ぐ。また、角座金１０は、リブ１３を介して被螺着体３０の表面との保持力を高め、角座金１０と被螺着体３０とが相対的に移動することを防ぐ。   Please refer to FIG. 3 and FIG. As shown in FIGS. 3 and 4, when actually used, first, a spring washer 40 is disposed below the head 22 of the screw 20, and then the shaft 21 of the screw 20 is inserted into the hole 113 to be covered. After alignment with the screw hole 31 of the screw body 30, the head 22 of the screw 20 is rotated to screw the shaft 21 into the screw hole 31. At this time, the square washer 10 is positioned between the head 22 and the member to be screwed 30, and the rib 13 is brought into contact with the surface of the member to be screwed 30. The head 22 is brought into contact with the first surface 111 via a spring washer 40, and a part of the plurality of ribs 13 is positioned between the head 22 and the screwed body 30 and the head 22. And pressure is applied to the plate body 11 via the spring washer 40. The plurality of ribs 13 can increase the structural strength of the square washer 10 and can withstand the pressure applied by the head 22 around the perforations 113. The plurality of ribs 13 and the plurality of concave grooves 15 extend from the center of the square washer 10 toward the periphery, disperse the pressure applied to the square washer 10 from the head 22, and stress concentrates around the perforations 113. Therefore, the square washer 10 is prevented from being deformed and damaged. Further, the square washer 10 increases the holding force with the surface of the screwed body 30 via the ribs 13 and prevents the square washer 10 and the screwed body 30 from moving relatively.

また、角座金１０は、複数のリブ１３と複数の凹溝１５とにより構造強度が高くなるため、ビス２０を螺着する際、角座金１０は変形しない上、角座金１０の中央が凹んでその周囲が反り上がることを防ぐことができるため、角座金１０と被螺着体３０との間の接触面積を大きくすることができる。例えば、被螺着体３０が端子台（図示せず）上の端子片である場合、端子台は、ビス２０を利用して角座金１０と端子片とを対応させて螺着し、外付け導線を堅牢に挟持すると、角座金１０が端子片上に平坦に密着されるため、角座金１０と端子片との間の接触面積が増大し、角座金１０と端子片との間の電気抵抗を減らし、角座金１０と端子片との間に挟持した外付け導線の電気的接続の状態が好ましいものとなる。   Further, since the square washer 10 has a high structural strength due to the plurality of ribs 13 and the plurality of concave grooves 15, when the screw 20 is screwed, the square washer 10 is not deformed and the center of the square washer 10 is recessed. Since the surroundings can be prevented from warping, the contact area between the square washer 10 and the body to be screwed 30 can be increased. For example, when the member 30 to be screwed is a terminal piece on a terminal block (not shown), the terminal block is screwed by using the screw 20 to correspond to the square washer 10 and the terminal piece, and externally attached. When the lead wire is firmly clamped, the square washer 10 is brought into close contact with the terminal piece so that the contact area between the square washer 10 and the terminal piece increases, and the electrical resistance between the square washer 10 and the terminal piece is increased. The state of electrical connection of the external conductors reduced and held between the square washer 10 and the terminal piece becomes preferable.

第１実施形態のリブ１３は、４つの直線リブ１３１を含む。これら複数の直線リブ１３１には、穿孔１１３に隣接した箇所から板体１１の周縁に向かって対称的に延設され、直線リブ１３１が穿孔１１３を中心として十字状に形成されている。複数の凹溝１５は、直線リブ１３１に対応した４つの直線凹溝を含む。板体１１は正方形を呈し、直線リブ１３１はそれぞれ同じ長さを有する。そのため、頭部２２と角座金１０との間に発生する圧力は、角座金１０から垂直に延びた２つの直線方向で均一に分散されて支えられ、角座金１０の中央に応力が集中することを防ぐことができる。   The rib 13 of the first embodiment includes four straight ribs 131. The plurality of linear ribs 131 are symmetrically extended from the position adjacent to the perforations 113 toward the periphery of the plate body 11, and the linear ribs 131 are formed in a cross shape with the perforations 113 as the center. The plurality of grooves 15 include four straight grooves corresponding to the straight ribs 131. The plate 11 has a square shape, and the linear ribs 131 have the same length. Therefore, the pressure generated between the head 22 and the square washer 10 is uniformly distributed and supported in two linear directions extending vertically from the square washer 10, and stress is concentrated at the center of the square washer 10. Can be prevented.

第１実施形態のリブ１３は、環状リブ１３２を含む。環状リブ１３２は、穿孔１１３を取り囲むように設けられ、直線リブ１３１は、板体１１の周縁に向かって対称的に延びて環状リブ１３２の外側に延設されている。複数の凹溝１５は、環状リブ１３２に対応した環凹溝を含み、実際に使用する際、環状リブ１３２は、被螺着体３０の表面に当接され、穿孔１１３の周囲が環状リブ１３２により支えられ、頭部２２に印加される圧力により角座金１０が変形することを防ぐ。また、スプリングワッシャ−４０の一部は、環状凹溝中に収容される。   The rib 13 of the first embodiment includes an annular rib 132. The annular rib 132 is provided so as to surround the perforation 113, and the linear rib 131 extends symmetrically toward the peripheral edge of the plate body 11 and extends outside the annular rib 132. The plurality of concave grooves 15 include annular concave grooves corresponding to the annular ribs 132. When actually used, the annular ribs 132 are brought into contact with the surface of the screwed body 30, and the periphery of the perforations 113 is the annular ribs 132. The square washer 10 is prevented from being deformed by the pressure applied to the head 22. A part of the spring washer 40 is accommodated in the annular groove.

第１実施形態の板体１１の四隅には、第２の表面１１２に向かって僅かに折り曲げられた折り曲げ部１１４がそれぞれ設けられ、ビス２０が螺着されると、板体１１の四隅が被螺着体３０の表面に当接され、角座金１０の支持力を高め、角座金１０の構造強度を高めることができる。   Folded portions 114 slightly bent toward the second surface 112 are provided at the four corners of the plate body 11 of the first embodiment, and when the screws 20 are screwed, the four corners of the plate body 11 are covered. Abutting on the surface of the screw body 30, the supporting force of the square washer 10 can be increased, and the structural strength of the square washer 10 can be increased.

（第２実施形態）
図５及び図６を参照する。図５は、本考案の第２実施形態に係る角座金を示す正面斜視図である。図６は、本考案の第２実施形態に係る角座金を示す背面斜視図である。図５及び図６に示すように、本考案の第２実施形態に係る角座金１０’は、板体１１、複数のリブ１３及び複数の凹溝１５から構成されてなる。複数のリブ１３は、４つの直線リブ１３１及び環状リブ１３２を含む。環状リブ１３２は、穿孔１１３を取り囲むようにその周囲に設けられている。複数の直線リブ１３１は、穿孔１１３に隣接した箇所から板体１１の周縁に向かって対称的に延設され、複数の直線リブ１３１が穿孔１１３を中心に十字状に形成されている。第２実施形態は、板体１１が長方形を呈し、複数の直線リブ１３１が互いに対応した２つの長めの直線リブ１３１と、二つの短めの直線リブ１３１と、を含む点が第１実施形態と異なる。 (Second Embodiment)
Please refer to FIG. 5 and FIG. FIG. 5 is a front perspective view showing a square washer according to a second embodiment of the present invention. FIG. 6 is a rear perspective view showing a square washer according to a second embodiment of the present invention. As shown in FIGS. 5 and 6, the square washer 10 ′ according to the second embodiment of the present invention includes a plate body 11, a plurality of ribs 13, and a plurality of concave grooves 15. The plurality of ribs 13 include four straight ribs 131 and an annular rib 132. The annular rib 132 is provided around the perforation 113 so as to surround it. The plurality of straight ribs 131 are symmetrically extended from the position adjacent to the perforations 113 toward the periphery of the plate body 11, and the plurality of straight ribs 131 are formed in a cross shape with the perforations 113 as the center. The second embodiment is different from the first embodiment in that the plate body 11 has a rectangular shape, and a plurality of linear ribs 131 includes two long linear ribs 131 corresponding to each other and two short linear ribs 131. Different.

図７を参照する。図７に示すように、実際に使用する際、まず、ビス２０の頭部２２の下方に、スプリングワッシャ−４０を配設してから、ビス２０の軸２１を穿孔１１３に挿通させ、被螺着体３０のビス孔３１に位置合わせさせる。続いて、ビス２０の頭部２２を回転させ、ビス孔３１中に軸２１を螺着させると、角座金１０’が頭部２２と被螺着体３０との間に位置する。複数のリブ１３の直線リブ１３１及び環状リブ１３２が被螺着体３０の表面に密着され、頭部２２は、スプリングワッシャ−４０を介して第１の表面１１１に当接される。複数の直線リブ１３１の一部及び環状リブ１３２は、頭部２２と被螺着体３０との間に位置して頭部２２を支え、スプリングワッシャ−４０を介して板体１１に圧力が伝えられる。複数の直線リブ１３１及び環状リブ１３２は、角座金１０’の構造強度を高め、頭部２２と角座金１０’との間の圧力が角座金１０’上の垂直の２直線方向で分散されて支えられるため、角座金１０’の中央に応力が集中することを防ぎ、穿孔１１３の周囲を環状リブ１３２により支え、角座金１０’が変形することを防ぐ。   Please refer to FIG. As shown in FIG. 7, when actually used, first, a spring washer 40 is disposed below the head portion 22 of the screw 20, and then the shaft 21 of the screw 20 is inserted through the perforation 113 to be screwed. It is aligned with the screw hole 31 of the adherend 30. Subsequently, when the head 22 of the screw 20 is rotated and the shaft 21 is screwed into the screw hole 31, the square washer 10 ′ is positioned between the head 22 and the screwed body 30. The straight ribs 131 and the annular ribs 132 of the plurality of ribs 13 are in close contact with the surface of the body to be screwed 30, and the head portion 22 is in contact with the first surface 111 via the spring washer 40. A part of the plurality of linear ribs 131 and the annular rib 132 are located between the head 22 and the screwed body 30 to support the head 22, and pressure is transmitted to the plate body 11 via the spring washer 40. It is done. The plurality of linear ribs 131 and the annular ribs 132 increase the structural strength of the square washer 10 ′, and the pressure between the head 22 and the square washer 10 ′ is distributed in two perpendicular linear directions on the square washer 10 ′. Since it is supported, stress is prevented from concentrating at the center of the square washer 10 ′, and the periphery of the perforation 113 is supported by the annular rib 132 to prevent the square washer 10 ′ from being deformed.

第２実施形態の板体１１の４隅には、第２の表面１１２に向かって僅かに折り曲がった折り曲げ部１１４がそれぞれ形成され、板体１１の４隅が被螺着体３０の表面に当接されるため、角座金１０’の支持力が高まり、角座金１０’の構造強度を高めることができる。   Folded portions 114 slightly bent toward the second surface 112 are formed at the four corners of the plate body 11 of the second embodiment, respectively, and the four corners of the plate body 11 are formed on the surface of the screwed body 30. Because of the contact, the supporting force of the square washer 10 ′ is increased, and the structural strength of the square washer 10 ′ can be increased.

上述したことから分かるように、本考案の角座金は、板体上に形成した複数のリブ及び複数の凹溝により全体の構造強度を高め、ビスにより角座金を被螺着体上に固定させるため、角座金が変形されることを防ぎ、角座金と被螺着体との間の接触面積及び保持力を高めることができる。   As can be seen from the above, the square washer of the present invention increases the overall structural strength by a plurality of ribs and a plurality of concave grooves formed on the plate, and the square washer is fixed on the screwed body by screws. Therefore, the square washer can be prevented from being deformed, and the contact area and the holding force between the square washer and the screwed body can be increased.
