Description

本発明は、水分測定を行う際に用いられるパウダーインジェクタに関し、特に、測定容器に容易に装着できるように構成したパウダーインジェクタに関する。   The present invention relates to a powder injector used when performing moisture measurement, and more particularly to a powder injector configured to be easily mounted on a measurement container.

従来、パウダーインジェクタ１００を滴定容器に装着するために、図３に示すように、パウダーインジェクタ１００に設けた装着栓１０１を滴定容器１０２の受け口に嵌合する手段をとっていた（例えば、特許文献１参照）。
図３は従来のパウダーインジェクタの装着状態を説明する図である。
図３のパウダーインジェクタ１００は、プランジャをバレル１０４の貫通孔に挿通配置し、そのバレル１０４を装着栓１０１に挿通嵌合してある。バレル１０４に対する装着栓１０１の装着位置は、嵌合状態のまま相互に摺動させて変更する。このパウダーインジェクタ１００を取り付ける滴定容器１０２は、発生液１０５を入れた容器本体１０６をアダプタ部材１０７で蓋をし、この蓋に乾燥筒１０８や検出電極等１０９が設けられている。 Conventionally, in order to attach the powder injector 100 to the titration container, as shown in FIG. 3, a means for fitting the mounting plug 101 provided on the powder injector 100 into the receiving port of the titration container 102 has been taken (for example, Patent Documents). 1).
FIG. 3 is a diagram for explaining a mounting state of a conventional powder injector.
In the powder injector 100 shown in FIG. 3, a plunger is inserted into the through hole of the barrel 104, and the barrel 104 is inserted and fitted into the mounting plug 101. The mounting position of the mounting plug 101 with respect to the barrel 104 is changed by sliding each other in the fitted state. In the titration container 102 to which the powder injector 100 is attached, a container body 106 containing a generated liquid 105 is covered with an adapter member 107, and a drying cylinder 108, a detection electrode 109, and the like are provided on the lid.

容器本体１０６の側壁には、中空開孔を有する裁頭円錐台形状の受け口１０３が設けられている。受け口１０３には、パウダーインジェクタ１００の装着栓１０１が嵌合されている。装着栓１０１は、裁頭円錐台形状の受け口１０３に整合するように、外形が同じく中空開孔の裁頭円錐台形状に形成されたテーパー部１１０と、該テーパー部１１０に連設され、該テーパー部１１０より大径のストッパ部１１１とから構成されている。装着栓１０１の中空開孔１１２内には、バレル１０４が挿入嵌合されている。   On the side wall of the container main body 106, a truncated conical receiving port 103 having a hollow opening is provided. A fitting plug 101 of the powder injector 100 is fitted into the receptacle 103. The mounting plug 101 is connected to the tapered portion 110, the tapered portion 110 having the same outer shape formed in the truncated truncated cone shape so as to be aligned with the truncated cone shaped receiving port 103, and the tapered portion 110, The stopper portion 111 has a diameter larger than that of the tapered portion 110. A barrel 104 is inserted and fitted into the hollow hole 112 of the mounting plug 101.

パウダーインジェクタ１００の装着栓１０１を受け口１０３に取り付ける時、パウダーインジェクタ１００のバレル１０４は、容器本体１０２の受け口１０３から内部に挿入され、バレル１０４先端が発生液１０５内に浸積される。これに伴って、装着栓１０１のテーパー部１１０が容器本体１０２の受け口１０３内に挿通嵌合される。これにより、受け口１０３に対する装着栓１０１の嵌合位置は特定の位置に決まってしまう。このとき、受け口１０３の先端と装着栓１０１のストッパ部１１１が当接して挿入状態が停止することも有る。
特開２００３−２６２６１５号公報 When the mounting plug 101 of the powder injector 100 is attached to the receptacle 103, the barrel 104 of the powder injector 100 is inserted into the container body 102 from the receptacle 103, and the tip of the barrel 104 is immersed in the generated liquid 105. Accordingly, the tapered portion 110 of the mounting plug 101 is inserted and fitted into the receiving port 103 of the container main body 102. As a result, the fitting position of the mounting plug 101 with respect to the receiving port 103 is determined to be a specific position. At this time, the distal end of the receiving port 103 and the stopper 111 of the mounting plug 101 may come into contact with each other and the insertion state may stop.
JP 2003-262615 A

この装着栓１０１は、一度、受け口１０３に装着栓１０１のテーパー部１１０が嵌合してしまうと、受け口１０３に対する位置を変更することができない。
また、この装着栓１０１は、受け口１０３の先端に装着栓１０１のストッパ部１１１が当接してしまうと、受け口１０３に対する位置を変更することができない。いずれの場合も、それ以上は挿入位置の調整ができない。バレル１０４に対する装着栓１０１の取り付け位置が不適切の場合には、バレル１０４の先端が滴定容器１０２内の発生液１０５内に届かない場合や、バレル１０４の先端が滴定容器１０２の底に当接してしまって、先端に収納されている試料がプランジャを押下げても排出できない場合等の不都合が発生する。 Once the tapered portion 110 of the mounting plug 101 is fitted into the receiving port 103, the mounting plug 101 cannot change its position with respect to the receiving port 103.
In addition, the position of the mounting plug 101 with respect to the receiving port 103 cannot be changed if the stopper 111 of the mounting plug 101 comes into contact with the tip of the receiving port 103. In either case, the insertion position cannot be adjusted any further. When the mounting position of the mounting plug 101 with respect to the barrel 104 is inappropriate, the tip of the barrel 104 does not reach the generated liquid 105 in the titration vessel 102, or the tip of the barrel 104 abuts against the bottom of the titration vessel 102. Thus, inconvenience occurs when the sample stored at the tip cannot be discharged even if the plunger is pushed down.

このような場合には、滴定容器１０２の受け口１０３からパウダーインジェクタ１００の装着栓１０１を引き抜き、バレル１０４に対する装着栓１０１の取り付け位置を調整した後、再度、滴定容器１０２にパウダーインジェクタ１００を装着し、装着栓１０１を滴定容器１０２の受け口１０３に嵌合することになる。
このような問題が発生すると、正確に秤量された粉末試料の全量を、測定直前まで外気及び滴定容器中の雰囲気と接触させることなく、発生液に直接投入することができない。 In such a case, after removing the mounting plug 101 of the powder injector 100 from the receiving port 103 of the titration container 102 and adjusting the mounting position of the mounting plug 101 with respect to the barrel 104, the powder injector 100 is mounted on the titration container 102 again. The fitting plug 101 is fitted into the receiving port 103 of the titration container 102.
When such a problem occurs, the entire amount of the accurately weighed powder sample cannot be directly put into the generated liquid without being brought into contact with the outside air and the atmosphere in the titration container until immediately before the measurement.

本発明の目的は、上記問題点に鑑み、容器に装着した状態でも、装着位置の調整ができるパウダーインジェクタを提供することにある。   In view of the above problems, an object of the present invention is to provide a powder injector capable of adjusting the mounting position even when mounted on a container.

At this time, the flange plate 5 is brought into contact with the flange portion 12 of the cylinder member 3, and the support portion 14 of the elastic locking member 4 is brought into contact with the flange plate 5. From this state, the cylinder member 3 is inserted into the opening 21 of the fitting portion 19 of the sheath member 6 so that the fitting portion 19 contacts the end of the support portion 14 in the bulging portion 15 of the elastic locking member 4. Insert it in the fitted state until it touches. As a result, the assembled state shown in FIG.

図２は本発明の組み立てられたパウダーインジェクタを容器の受け口に装着した状態を説明する図である。図２において、図１で使用されている符号と同じものは図１の説明を援用する。
図１（ｊ）に示された組立状態のパウダーインジェクタ１を、滴定容器２４の容器本体２５に形成した受け口２６に挿入し、弾性係止部材４を受け口２６に挿入嵌合する。このとき、鞘部材６の先端の透孔２３およびシリンダ部材３の先端が発生液２７中に挿入されていない場合、シリンダ部材３のフランジ部１２やフランジ板５を手で持ってパウダーインジェクタ１を受け口２６中へ押し込む。その際、膨出部１５は、その弾性を付与する膨出部１５の構成により中心方向へ弾性変形することにより、受け口２６内を該受け口と嵌合状態のまま摺動して位置変更することができる。 FIG. 2 is a view for explaining a state in which the assembled powder injector of the present invention is attached to the receptacle of the container. In FIG. 2, the same reference numerals used in FIG. 1 refer to the description of FIG. 1.
The powder injector 1 in the assembled state shown in FIG. 1 (j) is inserted into a receiving port 26 formed in the container body 25 of the titration container 24, and the elastic locking member 4 is inserted and fitted into the receiving port 26. At this time, when the through hole 23 at the tip of the sheath member 6 and the tip of the cylinder member 3 are not inserted into the generated liquid 27, the powder injector 1 is held by holding the flange portion 12 or the flange plate 5 of the cylinder member 3 by hand. Push into the receptacle 26. At that time, the bulging portion 15 is elastically deformed in the center direction by the configuration of the bulging portion 15 that imparts its elasticity, so that the position of the bulging portion 15 is slid while being fitted to the receiving port 26 and changed in position. Can do.

図１（ｋ）は本発明の弾性係止部材の実施例２を示す図である。
図１（ｋ）の弾性係止部材は、図１（ｆ）の弾性係止部材と比べると、狭持部を省略した膨出部の構成となっている。このように狭持部を省略することにより、狭持部１８と鞘部材６の嵌合状態がなくなるので、その分、膨出部１５は変形が容易になり、受け口２６の開口サイズが多少狭くても最適な位置まで容易に挿入嵌合することができる。 FIG. 1 (k) is a view showing Example 2 of the elastic locking member of the present invention.
The elastic locking member of FIG. 1 (k) has a bulging portion configuration in which the holding portion is omitted as compared with the elastic locking member of FIG. 1 (f). By omitting the pinching portion in this manner, the fitting state between the pinching portion 18 and the sheath member 6 is eliminated, and accordingly, the bulging portion 15 is easily deformed, and the opening size of the receiving port 26 is somewhat narrow. However, it can be easily inserted and fitted to the optimum position.

図１（ｌ）は本発明の弾性係止部材の実施例３を示す図である。
図１（ｌ）の弾性係止部材は、図１（ｆ）の弾性係止部材４と比べると、支持部１４の面に対する立ち上がり部の立ち上がり角度を、図１（ｆ）では鈍角（反時計回り方向で）としているのに対し、図１（ｌ）では鋭角（弾性係止部材の中心軸方向でみて、図１（ｆ）のものと比べ反対向き）となっている。これにより、膨出部１５ａはそれぞれ変形した立ち上がり部１６ａ、摺接部１７ａ、狭持部１８ａから構成されることになる。このように立ち上がり角度を変えたことにより、膨出部１５ａの弾発力が弱くなり、膨出部１５ａの変形がさらに容易になる。 FIG. 1 (l) is a view showing Example 3 of the elastic locking member of the present invention.
The elastic locking member of FIG. 1 (l) has a rising angle of the rising portion with respect to the surface of the support portion 14 as compared to the elastic locking member 4 of FIG. 1 (f), and an obtuse angle (counterclockwise) in FIG. In FIG. 1 (l), the angle is acute (in the direction opposite to that of FIG. 1 (f) when viewed in the central axis direction of the elastic locking member). Thereby, the bulging part 15a is comprised from the rising part 16a which deform | transformed, the sliding contact part 17a, and the clamping part 18a, respectively. By changing the rising angle in this way, the elastic force of the bulging portion 15a is weakened, and the deformation of the bulging portion 15a is further facilitated.

図１（ｍ）は本発明の弾性係止部材の実施例４を示す図である。
図１（ｍ）の弾性係止部材は、図１（ｆ）の弾性係止部材と比べると、膨出部１５ｂの断面形状が直線をつないで形成されている。特に、膨出部１５ｂの外側が、立ち上がり部１６ｂ、摺接部１７ｂ、狭持部１８ｂに分けて断面が直線で形成されている。これにより、摺接部１７ｂが受け口の面に広い範囲で密着できる。
以上説明した以外に、弾性係止部材は、以上の説明にあった各部分を組み合わせて構成することもできる。 FIG. 1 (m) is a view showing Example 4 of the elastic locking member of the present invention.
In the elastic locking member of FIG. 1 (m), the cross-sectional shape of the bulging portion 15b is formed by connecting straight lines as compared with the elastic locking member of FIG. 1 (f). In particular, the outside of the bulging portion 15b is divided into a rising portion 16b, a sliding contact portion 17b, and a holding portion 18b, and the cross section is formed in a straight line. As a result, the sliding contact portion 17b can be in close contact with the surface of the receiving port in a wide range.
In addition to the above description, the elastic locking member can be configured by combining the parts described above.
