Japanese Utility Model Publication No. 6-83973

本発明は、かかる不都合を解消して、ポンプブロックの機種によらずに、共通の防振ゴム部材を用いることができるポンプブロックの防振装置を提供することを目的とする。   It is an object of the present invention to provide a vibration isolator for a pump block that can eliminate such inconvenience and can use a common anti-vibration rubber member regardless of the type of pump block.

かかる目的を達成するために、本発明は、ポンプとポンプモータとからなるポンプブロックと、該ポンプブロックを基台に取り付けたときに該ポンプブロックと該基台との間に配設されて該ポンプブロック駆動時の振動を低減する防振ゴム部材とを備えるポンプブロックの防振装置において、ポンプとポンプモータとを支持する支持部材と、ポンプモータが載置される天板部と該天板部から垂下される角筒状の脚部とを備える防振ゴム部材と、該天板部と一体的に形成されて該支持部材に接続される金属製の接続部材と、該脚部と一体的に形成されて該脚部を該基台に取り付ける金属製の取付部材とを備えることを特徴とする。   In order to achieve such an object, the present invention provides a pump block comprising a pump and a pump motor, and is disposed between the pump block and the base when the pump block is attached to the base. In a vibration isolator for a pump block including a vibration isolating rubber member that reduces vibration when the pump block is driven, a support member that supports the pump and the pump motor, a top plate portion on which the pump motor is mounted, and the top plate Anti-vibration rubber member provided with a rectangular tube-like leg part hanging from the part, a metal connection member formed integrally with the top plate part and connected to the support member, and integral with the leg part And a metal attachment member for attaching the leg portion to the base.

本発明のポンプブロックの防振装置によれば、前記ポンプとポンプモータとからなるポンプブロックは前記支持部材により支持され、該支持部材を介して、前記防振ゴム部材の天板部と一体的に形成された接続部材に接続される。従って、前記ポンプブロックの機種に応じて前記支持部材を変えればよく、前記防振ゴム部材は該ポンプブロックの機種によらず共通に用いることができる。   According to the vibration isolator for a pump block of the present invention, the pump block including the pump and the pump motor is supported by the support member, and is integrated with the top plate portion of the vibration isolation rubber member via the support member. It is connected to the connecting member formed in the above. Therefore, the support member may be changed according to the model of the pump block, and the anti-vibration rubber member can be commonly used regardless of the model of the pump block.

また、本発明のポンプブロックの防振装置によれば、前記防振ゴム部材は、前記接続部材を備えるので前記ポンプブロックの組み付けを容易に行うことができ、しかも、前記天板部から垂下される脚部に一体的に形成された取付部材を備えるので前記基台への取り付けを容易に行うことができる。   Further, according to the vibration isolator for a pump block of the present invention, the vibration isolating rubber member includes the connection member, so that the pump block can be easily assembled and is suspended from the top plate portion.

本実施形態の防振装置１では、まず、取付部材２１の取付孔部２１ａを用いて、防振ゴム部材７の脚部１５を図示しない基台に螺着する。次に、ブラケット５の接続片６と防振ゴム部材７の接続部材８とを、ビス孔６ａ，８ａを用いてビス止めし、ブラケット５と接続部材８とを接続する。このとき、ブラケット５の係止片９ａ，９ｂを、防振ゴム部材７の庇凹部１６ｂに係止する。そして、ブラケット５のモータ取付孔部１２にポンプ本体３を、ポンプ取付孔部１３にポンプモータ４をそれぞれ螺着することにより、ポンプブロック２をブラケット５に支持させる。従って、ポンプブロック２の組み付け、脚部１５の前記基台への取り付けを容易に行うことができる。   In the vibration isolator 1 of the present embodiment, first, the leg portion 15 of the vibration isolating rubber member 7 is screwed to a base (not shown) using the mounting hole 21 a of the mounting member 21. Next, the connection piece 6 of the bracket 5 and the connection member 8 of the vibration isolating rubber member 7 are screwed using the screw holes 6a and 8a, and the bracket 5 and the connection member 8 are connected. At this time, the locking pieces 9 a and 9 b of the bracket 5 are locked to the flange recess 16 b of the vibration isolating rubber member 7. The pump block 2 is supported by the bracket 5 by screwing the pump body 3 into the motor mounting hole 12 of the bracket 5 and the pump motor 4 into the pump mounting hole 13. Therefore, the assembly of the pump block 2 and the attachment of the leg portion 15 to the base can be easily performed.

本実施形態の防振装置１によれば、ポンプブロック２は前述のようにブラケット５に支持されると共に、鍔状部４ａの下端部により防振ゴム部材７の上面に載置され、しかもブラケット５の係止部９ａ，９ｂが防振ゴム部材７の庇凹部１６ｂに係止されていることにより、その荷重が支持されている。ブラケット５は上述のように接続部材８に接続されており、接続部材８は防振ゴム部材７と一体的に形成され、接続部材８を形成する金属板１７の大部分は天板部１４に内蔵されているので、接続部材８はブラケット５にかかるポンプブロック２の荷重を支持することができる。また、天板部１４に内蔵されている金属板１７は、上部からポンプモータ４の鍔状部４ａの下端部により押圧されているので、ブラケット５に対してポンプモータ４と反対側に螺着されているポンプ本体３の荷重を支持することができる。そして、この状態でポンプモータ４を駆動すると、その振動が防振ゴム部材７により吸収され、給湯器等に該振動が伝播することを防止することができる。   According to the vibration isolator 1 of the present embodiment, the pump block 2 is supported by the bracket 5 as described above, and is placed on the upper surface of the vibration isolating rubber member 7 by the lower end portion of the hook-shaped portion 4a. Since the five locking portions 9a and 9b are locked to the flange recess 16b of the vibration isolating rubber member 7, the load is supported. The bracket 5 is connected to the connection member 8 as described above. The connection member 8 is formed integrally with the vibration isolating rubber member 7, and most of the metal plate 17 forming the connection member 8 is attached to the top plate portion 14. Since it is built in, the connecting member 8 can support the load of the pump block 2 on the bracket 5. Further, since the metal plate 17 built in the top plate portion 14 is pressed from above by the lower end portion of the bowl-shaped portion 4a of the pump motor 4, it is screwed to the bracket 5 on the opposite side to the pump motor 4. The load of the pump main body 3 currently made can be supported. When the pump motor 4 is driven in this state, the vibration is absorbed by the vibration isolating rubber member 7 and can be prevented from propagating to the water heater or the like.

また、本実施形態の防振装置１によれば、ポンプブロック２はブラケット５に支持され、ブラケット５を介して防振ゴム部材７の接続部材８に接続される。従って、ポンプブロック２の機種を変更するときには、ポンプブロック２の機種に応じてブラケット５の仕様を変更すればよく、防振ゴム部材７はポンプブロック２の機種によらず共通に用いることができる。   Further, according to the vibration isolator 1 of the present embodiment, the pump block 2 is supported by the bracket 5 and connected to the connection member 8 of the vibration isolating rubber member 7 via the bracket 5. Therefore, when the model of the pump block 2 is changed, the specification of the bracket 5 may be changed according to the model of the pump block 2, and the anti-vibration rubber member 7 can be used in common regardless of the model of the pump block 2. .

ところで、本実施形態の防振装置１では、図５（ａ）、図６（ａ）に示すように、天板部１４には金属板１７が内蔵されており、脚部１５の下部、接地部１９には金属板２０が内蔵されており、金属板１７，２０が防振ゴム部材７の補強材として作用する。しかし、脚部１５において、金属板１７，２０の間の部分はゴムのみからなり、補強材が含まれていない。このとき、防振装置１が備えられている給湯器等の梱包が落下する等して大きな衝撃が加わると、防振ゴム部材７は図５（ａ）、図６（ａ）に矢示する垂直方向、水平方向に大きく変形して、ポンプブロック２を支持できなくなることが懸念される。   By the way, in the vibration isolator 1 of this embodiment, as shown to Fig.5 (a) and FIG.6 (a), the metal plate 17 is incorporated in the top-plate part 14, and the lower part of the leg part 15, grounding is carried out. The metal plate 20 is built in the part 19, and the metal plates 17, 20 act as a reinforcing material for the vibration isolating rubber member 7. However, in the leg part 15, the part between the metal plates 17 and 20 consists only of rubber | gum, and the reinforcing material is not contained. At this time, when a large impact is applied, for example, when a package such as a water heater provided with the vibration isolator 1 is dropped, the vibration isolator rubber member 7 is indicated by arrows in FIGS. 5 (a) and 6 (a). There is a concern that the pump block 2 cannot be supported due to significant deformation in the vertical and horizontal directions.

そこで、本実施形態の防振装置１において、防振ゴム部材７は図５（ｂ）、図６（ｂ）に示すように、天板部１４に内蔵される金属板１７が脚部１５内部に垂下するクランク状の第１の変形規制部材２２を備え、脚部１５の下部に内蔵される金属板２０が脚部１５内部に垂直に起立する第２の変形規制部材２３を備えるものであってもよい。   Therefore, in the vibration isolator 1 of the present embodiment, as shown in FIG. 5B and FIG. 6B, the vibration isolating rubber member 7 has a metal plate 17 built in the top plate portion 14 provided inside the leg portion 15. The first deformation restricting member 22 has a crank shape that hangs down from the bottom, and the metal plate 20 built in the lower portion of the leg portion 15 includes a second deformation restricting member 23 that stands vertically inside the leg portion 15. May be.

第１の変形規制部材２２は、図７に示すように、天板部１４に内蔵される金属板１７から脚部１５内に金属板２０方向に延出される接続部２２ａと、接続部２２ａの先端から金属板１７と平行な方向に延出される腕部２２ｂと、腕部２２ｂの先端からさらに金属板２０方向に延出される先端部２２ｃとからなり、接続部２２ａ、腕部２２ｂ、先端部２２ｃによりクランク形状が形成されている。第２の変形規制部材２３は、第１の変形規制部材２２に対し、垂直方向では先端２３ａが腕部２２ｂに対向し、水平方向では第２の変形規制部材２３自体が先端部２２ｃに対向して配設されている。   As shown in FIG. 7, the first deformation restricting member 22 includes a connection portion 22a extending in the direction of the metal plate 20 from the metal plate 17 built in the top plate portion 14 into the leg portion 15, and a connection portion 22a. It consists of an arm portion 22b extending from the tip in a direction parallel to the metal plate 17, and a tip portion 22c extending further from the tip of the arm portion 22b in the direction of the metal plate 20, and includes a connecting portion 22a, an arm portion 22b, and a tip portion. A crank shape is formed by 22c. The second deformation regulating member 23 is opposite to the first deformation regulating member 22 in the vertical direction with the tip 23a facing the arm portion 22b and in the horizontal direction the second deformation regulating member 23 itself faces the tip portion 22c. Arranged.

前記構成によれば、防振ゴム部材７に梱包落下時等の大きな衝撃が加わったときに、垂直方向では、第２の変形規制部材２３の先端２３ａと、第１の変形規制部材２２の腕部２２ｂとが、防振ゴム部材７を形成するゴムを介して相互に近接することにより、脚部１５の変形が規制される。また、水平方向では、第２の変形規制部材２３自体と、第１の変形規制部材２２の先端部２２ｃとが防振ゴム部材７を形成するゴムを介して相互に近接することにより、脚部１５の変形が規制される。   According to the above configuration, when a large impact is applied to the anti-vibration rubber member 7 such as when the package is dropped, the distal end 23a of the second deformation restriction member 23 and the arm of the first deformation restriction member 22 are vertically aligned. The deformation of the leg portion 15 is restricted when the portion 22b comes close to each other through the rubber forming the anti-vibration rubber member 7. Further, in the horizontal direction, the second deformation regulating member 23 itself and the tip 22c of the first deformation regulating member 22 are close to each other via rubber forming the vibration isolating rubber member 7, whereby the leg portion 15 deformations are regulated.

従って、防振ゴム部材７は、梱包落下時等の大きな衝撃が加わったときにも、変形を低減することができ、ポンプブロック２を確実に支持することができる。   Therefore, the anti-vibration rubber member 7 can reduce deformation even when a large impact is applied such as when the package is dropped, and can reliably support the pump block 2.
