本発明は、容器を密閉するカバーを、容器のフランチに
結合する場合等に用いるボルトに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a bolt used for coupling a cover for sealing a container to a flange of the container.

支腕（１２）及びポル） （１３）の加工が面倒であっ
た。For example, when bolting a cover to the flange at the end of a container where internal pressure is applied, conventionally, as shown in Figure 5, it is often tightened with a commercially available pol (10) and nut (11). If the cover (5) is flanched (6
), use two spanners to remove the bolt (
10) and nut (11) had to be turned in opposite directions. Also, as illustrated in Fig. 5, bolts (13
) with the head of the support arm (12) fixed to the side wall (7) of the container body.
), fit the bolt (13) into the notch (4) provided in the cover (5) and flange (6), and then tighten the nut (14).
) was tightened. In this case, Natsu (1
It is easy to attach and detach as you only need to turn 4).
The machining of the support arm (12) and pole (13) was troublesome.
本発明は極めて安価で簡単な構造のボルトにより、１個
のスパナで迅速にカバーを脱着出来ることを目的とする
。An object of the present invention is to enable the cover to be quickly attached and detached using a single spanner using bolts that are extremely inexpensive and have a simple structure.
１個のスパナでナツトを確実に締め付ける為には、ボル
トが容器のフランチ（６）又はカバー（５）に対し、回
転が制約されればよい。In order to reliably tighten the nut with one wrench, the bolt only needs to be restricted from rotating relative to the flange (6) or cover (5) of the container.
カバー（５）、フランチ（６）に設けた切り込み溝（４
）に対してボルトの回転を防止するには、ボルトのねぢ

り込み溝（４）の側壁に当って、ボルトの回動が制約さ
れるようにすればよい。The cut groove (4) provided on the cover (5) and flange (6)
) To prevent the bolt from rotating against the bolt, provide a part of the threaded side of the bolt that protrudes more than the diameter of the bolt.
Either this protrusion hits the side wall of the notch (4) and its rotation is restricted, or a protrusion is provided on the back surface (9) of the bolt head (3), that is, on the thread side. , this protrusion may come into contact with the side wall of the cut groove (4), thereby restricting the rotation of the bolt.
［作 用］
第１図に例示するように、ボルト頭部（３）のボルト軸
部（１）側に突起部（２）を設ける。[Function] As illustrated in FIG. 1, a protrusion (2) is provided on the bolt shaft (1) side of the bolt head (3).
突起部（２）は第１図の平面図に示すように、はぼボル
ト径程度の巾があればよく、切り込み溝（４）に嵌れば
よい。又その高さ（ｈ）は、フランチ（６）及びカバー
（５）を合せた厚さ以下であればよいから、一般には３
〜５ＩＩＩＩ１１位あれば充分である。As shown in the plan view of FIG. 1, the protrusion (2) only needs to have a width approximately equal to the diameter of the bolt, and only needs to fit into the cut groove (4). In addition, its height (h) should be less than the combined thickness of the flange (6) and cover (5), so it is generally 3.
~5III11 is sufficient.
切り込み溝（４）の内側面に当って、ボルトの回動を制

いが、第７図に示するように、ボルト軸部（１）とボル
ト頭部（３）の双方に連接されたものである方が、強度
も大きく、製造も容易である。The purpose of this protrusion (2) is to hit the inner surface of the cut groove (4) and restrict the rotation of the bolt, so this protrusion (2) projects independently from the back surface (9) of the bolt head (3). It may be a piece that is straight or protrudes to the side of the bolt shaft (1), but as shown in Fig. 7, it may be connected to both the bolt shaft (1) and the bolt head (3). It is stronger and easier to manufacture.

ばよい。In order to use the bolt of the present invention, a cut groove (4) is provided at a position that matches both the flange (6) and the cover (5) as illustrated in FIGS. 4 and 5, and the bolt of the present invention is , and tighten with a nut (11) as shown in FIG. 6, or with a knob (15) as shown in FIG.
突起部（２）が切り込み溝（４）の内壁に当ってボルト
は回転しないから、１個のスパナ或は片手でカバー（５
）とフランチ（６）を簡単に着脱できる。Since the protrusion (2) hits the inner wall of the notch (4) and the bolt does not rotate, use one spanner or one hand to remove the cover (5).
) and flange (6) can be easily attached and detached.
本発明のボルトを使用すれば、１個のスパナでナツトを

、サービス性が向上する。Using the bolt of the present invention, the bolt can be removed laterally from the notch (4) by turning the nut with a single wrench or by slightly rotating the knob with one hand, allowing the flange (6) to be removed from the notch (4). Since the cover and cover (5) can be easily attached and removed and manufactured at low cost, serviceability can be improved if applied to equipment that requires disassembly and assembly, such as chemical equipment, pressure vessels, a number of tanks, etc.
