Description

本考案は、流体を噴射するノズルに係り、特に、流体供給管からの流体を噴射口から噴射するに好適なノズルに関する。 The present invention relates to a nozzle that ejects fluid, and more particularly to a nozzle that is suitable for ejecting fluid from a fluid supply pipe from an ejection port.

従来、ノズルとして、例えば、電気部品などの製造工程において、現像液、エッチング液、剥離液、洗浄液などの流体を噴霧するために、液体供給配管から供給される流体を噴霧するように構成されたスプレーノズルが知られている（特開２００２−３７００５１号公報参照）。 Conventionally, the nozzle is configured to spray a fluid supplied from a liquid supply pipe in order to spray a fluid such as a developing solution, an etching solution, a stripping solution, and a cleaning solution in a manufacturing process of an electrical component, for example. A spray nozzle is known (see JP 2002-370051 A).

このスプレーノズルは、液体供給配管から供給される液体をアダプタを介してノズル本体に流入し、流入された液体をノズル本体から噴霧対象に噴霧することができる。 This spray nozzle can flow the liquid supplied from the liquid supply pipe into the nozzle body via the adapter, and spray the flowed liquid from the nozzle body to the spray target.

しかし、従来技術では、ノズル本体に液体を流入するに際して、ノズル本体を弾性ゴムパッキンを介してアダプタに取り付け、アダプタを液体供給配管に取り付ける構造を採用しているので、ノズルの取付にアダプタが必要になるとともに、ノズルの取り付け作業が面倒である。 However, in the prior art, when the liquid flows into the nozzle body, the nozzle body is attached to the adapter via the elastic rubber packing, and the adapter is attached to the liquid supply pipe. At the same time, the nozzle mounting work is troublesome.

本考案は、前記従来技術の課題に鑑みて為されたものであり、その目的は、ノズルの取り付けを簡単にすることにある。 The present invention has been made in view of the problems of the prior art, and an object thereof is to simplify the mounting of the nozzle.

前記課題を解決するために、請求項１に係るノズルは、中空構造の流体流路を形成する胴体と、前記胴体に併設された筒体とを備え、前記胴体には、前記流体流路に連なる流体導入口が形成され、前記筒体には、前記胴体の流体流路に導入された流体を噴射するための噴射口が形成され、前記筒体外周面には、環状のねじ部が形成されてなる構成とした。 In order to solve the above-described problem, a nozzle according to claim 1 includes a body that forms a fluid flow path having a hollow structure, and a cylindrical body that is provided alongside the body.

When the body is rotated in this state, the nozzle can be easily attached to the attachment target by screwing the screw portion to be attached and the screw portion on the outer peripheral surface of the cylindrical body.

一方、取り付け対象に筒体外周面のねじ部と螺合可能なねじ部がなく、取り付け対象に筒体が挿入可能な貫通孔が形成されているときには、取り付け対象の貫通孔内に筒体を挿入し、貫通孔から突出した筒体外周面のねじ部に締結部材を装着し、筒体外周面のねじ部に締結部材のねじ部を噛み合せた状態で、締結部材を回転させると、締結部材のねじ部と筒体外周面のねじ部との螺合により、ノズルを取り付け対象に簡単に取り付けることができる。 On the other hand, when there is no threaded portion that can be screwed with the threaded portion on the outer peripheral surface of the cylinder, and the through hole into which the cylinder can be inserted is formed in the installation target, the cylinder is placed in the through hole of the installation target. When the fastening member is inserted into the threaded portion on the outer peripheral surface of the cylinder protruding from the through hole and the threaded portion of the fastening member is engaged with the threaded portion on the outer peripheral surface of the cylindrical body, the fastening member is rotated. The nozzle can be easily attached to the attachment target by screwing the screw part with the screw part on the outer peripheral surface of the cylindrical body.

請求項２に係るノズルは、請求項１に記載のノズルにおいて、前記胴体のうち前記筒体に隣接する部位は、前記筒体よりも径の大きい大径部として形成され、前記大径部のうち前記筒体との境界に位置する環状面は、前記胴体を取り付け対象に取り付けるときの取り付け面として形成されてなる構成とした。 The nozzle according to claim 2 is the nozzle according to claim 1, wherein a portion of the body adjacent to the cylindrical body is formed as a large-diameter portion having a larger diameter than the cylindrical body, Of these, the annular surface located at the boundary with the cylindrical body is formed as an attachment surface when the body is attached to an attachment target.

（作用）ノズルを取り付け対象に取り付けるときに、胴体の環状面が取り付け対象の表面に密着するまで、胴体または締結部材を回すことで、ノズルを取り付け対象に確実に取り付けることができる。 (Operation) When the nozzle is attached to the attachment target, the nozzle can be reliably attached to the attachment target by turning the trunk or the fastening member until the annular surface of the fuselage comes into close contact with the surface of the attachment target.

以上の説明から明らかなように、請求項１に係るノズルによれば、アダプタを用いることなく、ノズルを取り付け対象に簡単に取り付けることができる。 As apparent from the above description, according to the nozzle according to the first aspect, the nozzle can be easily attached to the attachment object without using an adapter.
