本考案は風雨に曝されかつ防水条件の厳しい屋
外に設置される例えば鉄道の電気転てつ機等の外
部機器に使用する防水パツキングに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to waterproof packing used for external equipment, such as electric railway switch machines, which are exposed to wind and rain and installed outdoors under severe waterproofing conditions.
従来、この種の防水パツキングとして第1図に
示すものがある。 Conventionally, there is a type of waterproof packing shown in FIG. 1.

器内への侵入を防止していた。 The figure shows the main parts of the container for attaching waterproof packing, and a top lid 2 is attached to a container main body 1 with an open top. A waterproof packing 4 having a substantially hollow rectangular cross section is fixed to the groove 3 formed at the edge of the upper lid 2 by adhesive or the like.
By pressing the lower end surface of the waterproof packing 4 against the upper end surface of the peripheral wall 1a of the container body 1, rainwater and the like are prevented from entering the container.

侵入し易かつた。 However, in such conventional waterproof packing, the waterproof packing 4 is fixed to the upper lid 2 side and its lower end surface is pressed against the upper end surface of the peripheral wall 1a of the container body 1 for sealing, so the sealing surface is only one surface. If heavy rain or water from snow-melting sprinklers falls on this seal from the side, or hits the ballast 5 and is thrown up, water will enter the container through the seal surface. It was easy.

止するようにしたものである。 This invention focuses on these conventional problems,
This was done to solve this problem. For this purpose, a waterproofing device is constructed by extending the inside and outside of the container at the bottom of the packing body to form a clamping part that clamps the opening edge of the container body, as well as forming a plurality of protrusions that are pressed into contact with the inner surface of the groove on the lid edge. By fixing the packing to the container body via the clamping portion, the sealing surface is formed in an upwardly concave shape to prevent rainwater from entering the container.
以下、本考案を第2図に示す一実施例に基づい
て説明する。 The present invention will be explained below based on an embodiment shown in FIG.

る。 In FIG. 2, a pair of seal pieces 12 are formed by extending downwardly from both sides of the lower end of a packing body 11, which is made of an elastic material and has a substantially hollow rectangular cross section, to form a holding portion having a U-shaped cross section. Further, a plurality of deformable protrusions 13 are erected on the outer wall of the packing main body 11 to serve as a sealing part, and these protrusions 13 are connected to the upper cover 14.
By coming into pressure contact with the inner surface of the groove 15, rainwater is prevented from entering the container through the inner surface of the groove 15.
そして、従来と同様の上面開放の容器本体16
の周囲壁16aの内外両側面をシール片12で挾
持し、この挾持部を接着剤で接着し、防水パツキ
ング17を容器本体16に固定する。 The container body 16 has an open top, similar to the conventional one.
The waterproof packing 17 is fixed to the container body 16 by sandwiching both the inner and outer surfaces of the surrounding wall 16a with the seal pieces 12, and bonding the sandwiched parts with an adhesive.
このようにすると、容器本体16と防水パツキ
ング17との当接面積(シール面積)が増加し、

る。 In this way, the contact area (sealing area) between the container body 16 and the waterproof packing 17 increases,
In addition, since the sealing surface is concave and bent upwards, it can more effectively prevent rainwater from entering the container than before, thereby preventing damage to, for example, electrical equipment inside the container or electrical leakage. can. In addition, since the deformable protrusion 13 is provided on the upper part of the packing body 11, the groove 1
The waterproof packing 17 can be smoothly inserted into the inside of the waterproof packing 17.
しかも、本実施例では上蓋14の外側縁部を従
来に較べ下方に延設し、パツキング本体11を覆
うようにしているので、容器内部への雨水の侵入
を更に効果的に防止できる。 Moreover, in this embodiment, the outer edge of the top lid 14 is extended downward compared to the conventional case to cover the packing body 11, so that rainwater can be more effectively prevented from entering the inside of the container.

雨水の侵入を防止できる。 As explained above, the present invention has a protruding holding part that holds the opening periphery of the container main body at the lower part of the waterproof packing, and a sealing part having a plurality of protrusions that are pressed against the inner surface of the groove of the lid. Since the packing is fixed to the container body side, the sealing surface has a bent shape and the sealing distance can be increased, improving sealing performance and preventing rainwater from entering the container.
