本考案は、車両用ラジエータ等の熱交換器用合成樹脂製タンクの外壁面にファ ンシュラウド等の部品を取付けるための雌螺子を収容する雌螺子保持部の構造に 関するものである。 The present invention relates to a structure of a female screw holding portion that accommodates a female screw for mounting a component such as a fan shroud on an outer wall surface of a synthetic resin tank for a heat exchanger such as a vehicle radiator.
【0002】[0002]
従来、熱交換器用合成樹脂製タンクの外壁面にファンシュラウド等の部品を取 付けるために、ナット等の雌螺子を収容する雌螺子保持部をタンク外壁面に一体 に形成したものがあった。 Conventionally, in order to mount parts such as fan shrouds on the outer wall surface of a synthetic resin tank for a heat exchanger, a female screw holding portion for housing a female screw such as a nut has been integrally formed on the outer wall surface of the tank.
【0003】 例えば、特開平1−131896号公報に記載されたものでは、図6に図示するよう に、タンク外壁面01に設けられたナット保持部02に収納されたナット03がこのナ ット保持部02より脱落しないようにするためにナット03に突起04を形成し、この 突起04をナット保持部02の外壁片05におけるボルト貫通孔06の上方切欠き07に係 合させるようになっていた。 また前記特開平1−131896号公報には他の実施例として、図7ないし図8に図 示するように、ナット03の後方に円筒部08を形成し、ナット保持部02の押え片09 を逆Ω状部010 に形成し、この逆Ω状部010 にナット03の円筒部08を嵌合させる ようになっていた。For example, in the one disclosed in JP-A-1-131896, as shown in FIG. 6, the nut 03 housed in the nut holding portion 02 provided on the outer wall surface 01 of the tank is the nut 03. A protrusion 04 is formed on the nut 03 so as not to fall off from the holding portion 02, and the protrusion 04 is adapted to be engaged with the upper cutout 07 of the bolt through hole 06 in the outer wall piece 05 of the nut holding portion 02. It was As another embodiment of the above-mentioned JP-A-1-131896, as shown in FIGS. 7 to 8, a cylindrical portion 08 is formed at the rear of the nut 03 and a holding piece 09 of the nut holding portion 02 is provided. The reverse Ω-shaped portion 010 was formed, and the cylindrical portion 08 of the nut 03 was fitted into the reverse Ω-shaped portion 010.
【0004】 しかしこれらの部品取付け構造では、いずれもナット03に突起04または円筒部 08を形成する必要があるので、普通の形状のナットを使用することができず、コ ストアップが避けられず、またナット保持部02には水抜き孔がないため、水が溜 ってナット03が腐食する惧れがあった。However, in any of these component mounting structures, it is necessary to form the protrusion 04 or the cylindrical portion 08 on the nut 03, so that it is not possible to use a nut having an ordinary shape, and cost increase cannot be avoided. Also, since the nut holding portion 02 does not have a water drain hole, there is a risk that water will collect and the nut 03 will corrode.
【0005】 このような欠点を除去したものとして本出願人が出願した実開平 3-71276号公 報に記載されたものでは、図9ないし図12に図示されるように、合成樹脂製タン ク011 に設けられたナット保持部012 の外壁片013 の頂部内面に係止突起014 を 形成するとともに、ナット保持部012 の底壁片015 に矩形状の水抜き孔016 を形 成することにより、普通の形状のナット017 を使用できるようにし、コストダウ ンと耐久性向上を図ったが、このような形状のナット保持部012 を合成樹脂製タ ンク011 と一体に成形するには、水抜き孔016 および係止突起014 の下面を画定 するための抜き型を下方から上方に向けて水抜き孔016 からナット保持部012 内 に装入する必要があり、タンク端縁部が外方に膨出した形状のタンク011 に、こ の構造を適用することができなかった。 なお外壁片013 にはボルト孔018 が形成され、水抜き孔016 より後方にU字状 の切欠き019 を有する薄い押え片020 が側壁片021 とは独立して立設されている 。[0005] As disclosed in Japanese Utility Model Laid-Open No. 3-71276, filed by the applicant of the present invention, in which such defects are eliminated, as shown in FIGS. 9 to 12, a synthetic resin tank is used. By forming the locking protrusion 014 on the inner surface of the top of the outer wall piece 013 of the nut holding portion 012 provided in 011 and forming the rectangular drain hole 016 in the bottom wall piece 015 of the nut holding portion 012, We have made it possible to use the nut 017 of ordinary shape to improve the cost down and durability, but in order to mold the nut holding part 012 of such shape with the synthetic resin tank 011 integrally, It is necessary to insert a cutting die for defining the lower surfaces of 016 and the locking projection 014 from the bottom to the top through the drain hole 016 into the nut holding part 012, and the tank edge part bulges outward. This structure can be applied to the tank 011 with the There was no. A bolt hole 018 is formed in the outer wall piece 013, and a thin pressing piece 020 having a U-shaped cutout 019 is provided rearward of the water draining hole 016 and is erected independently of the side wall piece 021.

本考案はこのような難点を克服した熱交換器用合成樹脂製タンクの雌螺子保持 部の改良に係り、熱交換器用合成樹脂製タンクの外壁面に雌螺子を収容できる雌 螺子保持部を一体に形成し、該雌螺子保持部を貫通して該雌螺子保持部内の雌螺 子に雄螺子を螺合緊締することにより、部品を取付けることができる部品取付け 構造において、前記雌螺子保持部は、前記タンクの外壁面より一体に突出した1 対の両側壁片と、前記雄螺子を嵌挿することができる雄螺子孔を備え該1対の両 側壁片の側縁に一体に結合された外壁片と、前記タンクの外壁面より一体に突出 するとともに前記両側壁片および外壁片の底縁に一体に結合された底壁片と、前 記タンク外壁に設けられた押え部分または該タンク外壁および外壁片間に配設さ れた押え片とよりなり、前記タンク外壁面に相対する外壁片内面の巾方向中央の 上部に、前記雌螺子上端と係脱自在に係合する係止突起が突設され、前記外壁片 には、前記底壁片上面および前記係止突起下面と同じ高さで連なった上下1対の 切欠きが前記雄螺子孔の上下に設けられたことを特徴とするものである。 The present invention relates to improvement of a female screw holding portion of a synthetic resin tank for a heat exchanger, which overcomes such difficulties, and an integrated female screw holding portion for housing a female screw is provided on an outer wall surface of the synthetic resin tank for a heat exchanger. In the component mounting structure in which the component is mounted by penetrating the female screw holding portion and screwing and tightening the male screw to the female screw in the female screw holding portion, the female screw holding portion includes: An outer wall integrally provided with a pair of both side wall pieces projecting integrally from the outer wall surface of the tank, and male screw holes into which the male screw can be inserted and connected to side edges of the pair of both side wall pieces. A piece, a bottom wall piece that integrally projects from the outer wall surface of the tank and is integrally connected to the bottom edges of the both side wall pieces and the outer wall piece, and a pressing portion provided on the tank outer wall or the tank outer wall, It is called a holding piece placed between the outer wall pieces. A locking projection that engages with the upper end of the female screw in a disengageable manner is projectingly provided at an upper portion of the inner surface of the outer wall piece facing the outer wall surface of the tank in the widthwise center, and the outer wall piece has the bottom wall piece. It is characterized in that a pair of upper and lower notches that are continuous at the same height as the upper surface and the lower surface of the locking projection are provided above and below the male screw hole.
【0007】 本考案は前記したように構成されているので、前記雌螺子保持部の上方から該 雌螺子保持部に向けて雌螺子を押込むだけで、前記外壁片上部が外方に向い弾性 変形し、該雌螺子は前記係止突起を乗越えて前記雌螺子保持部に装入される。 また本考案では、前記雌螺子保持部に装入された雌螺子は前記係止突起に係止 されているので、該雌螺子は前記雌螺子保持部から脱落することはない。Since the present invention is configured as described above, by simply pushing the female screw from above the female screw holding portion toward the female screw holding portion, the upper portion of the outer wall piece is elastically turned outward. After being deformed, the female screw rides over the locking projection and is inserted into the female screw holding portion. Further, in the present invention, since the female screw inserted in the female screw holding portion is locked by the locking protrusion, the female screw does not fall off from the female screw holding portion.
【0008】 さらに本考案においては、前記底壁上面と同じ高さで連なった切欠きが前記雄 螺子孔の下に設けられているため、たとえ前記底壁片に水抜き孔が形成されてい なくても、前記雌螺子保持部に浸入した水は、前記雄螺子孔の下の切欠きから外 部へ排出され、該雌螺子保持部内に水が溜ることがなく、雌螺子と雄螺子との螺 合部分や該雌螺子の腐食が未然に防止され、耐久性え大巾に向上する。Further, in the present invention, since the notch that is continuous with the upper surface of the bottom wall is provided under the male screw hole, even if the drain hole is not formed in the bottom wall piece. However, the water that has penetrated into the female screw holding portion is discharged to the outside through the notch below the male screw hole, and the water does not collect in the female screw holding portion. Corrosion of the screwed portion and the female screw is prevented in advance, and the durability is greatly improved.
【0009】 さらにまた本考案は前記したように構成されているため、前記雄螺子孔の上下 の切欠き面や、前記係止突起の下面や、前記底壁片の上面をそれぞれ画定するた めの抜き型を前記外壁片の外方から前記雄螺子孔内に装入するだけで、タンクお よび雌螺子保持部の金型を構成することができ、熱交換器用合成樹脂製タンクと これと一体の雌螺子保持部とを、頗る能率良く成型することができ、単純な形状 の雌螺子の使用と相俟って大巾なコストダウンを図ることができる。 しかも本考案では、抜き型を前記雌螺子保持部の下方から上方へ挿入する必要 がないため、該雌螺子保持部より下方のタンク外線部が外方へ膨出した形状のタ ンクも形成することができ、熱交換器用合成樹脂製タンク形状の自由度が頗る広 くなる。Furthermore, since the present invention is configured as described above, the upper and lower cutout surfaces of the male screw hole, the lower surface of the locking projection, and the upper surface of the bottom wall piece are defined. The mold for the tank and the female screw holding portion can be constructed by simply inserting the punching die into the male screw hole from the outside of the outer wall piece. The integral female screw holding portion can be molded with high efficiency, and in combination with the use of the female screw having a simple shape, the cost can be greatly reduced. Moreover, in the present invention, since it is not necessary to insert the punching die from the lower side to the upper side of the female screw holding portion, the tank outer wire portion below the female screw holding portion also forms a tank bulging outward. Therefore, the degree of freedom in the shape of the tank made of synthetic resin for the heat exchanger becomes extremely wide.
