８図に示す様なものが存在する。(Prior technology) Conventionally, this type of swingable pipe joint was manufactured by
There is a pipe joint as disclosed in Japanese Patent No. 52-19717, ie, as shown in FIG. 8 of the drawings.

ていた。 In other words, in these conventional pipe fittings, the joint body 22 having a spherical outer circumferential surface is attached to the pipe body 12.
The joint body 22 is fitted into the spherical recess 21 of the joint body 20 so as to be able to freely slide spherically. However, in this case, the joint body 20 that holds the joint body 22 having a spherical bulge cannot be constructed from a single member. The cap 20a and the cap 23 have to be divided into two parts, and as a result, the number of parts for the joint member increases, which poses a problem in its manufacturability.
よつて、従来に於いては、上記難点を解決する
ものとして、例えば実公昭49−9771号公報に所載

にて当接支持させてなるものである。 That is, as shown in FIG. 7, in this conventional joint, a spherical gasket 2e is externally fitted and fixed to a tube body 12 having an annular protrusion 30 projecting thereon, and the inner periphery of the other joint body 4e is Two protrusions 31, 3
1 to protrude, so that both ends of the gasket 2e fitted into the joint body 4e are connected to the protrusions 31, 31.
It is supported in contact with the

装着の確実性に大なる問題点を有していた。(Problems to be Solved by the Invention) However, in the conventional device, both ends of the gasket 2e made of only an elastic member are supported by two protrusions 31, 31. For example, when a force in the direction of arrow A acts on the pipe body 12 and a pulling force in the same direction acts on the seal 2e, the seal 2e is compressed and deformed to a diameter smaller than the inner diameter of the protrusion 31, and the joint body 4e This poses a serious problem in the reliability of attachment of the gasket 2, as there is a risk that the gasket may easily come off.

ある。 Incidentally, even if in the above-mentioned conventional method, the packing 2e installed in the joint body 4e is prevented from being easily reduced and deformed by increasing the outer diameter of the packing 2e, etc., the packing 2e may be easily compressed and deformed. If the force is large, not only will it not be possible to reliably prevent separation from the joint body 4e, but the larger the outer diameter of the seal 2e, the more difficult it will be to fit the seal 2e into the joint body 4e. A contradictory situation had arisen that made it difficult.

作業性を良好なものにする点にある。 The present invention was devised in view of the conventional problems as described above, and its purpose is to allow the packing to be installed inside the joint body without deteriorating the workability of installing the gasket into the joint body. The purpose is to reliably prevent the packing from accidentally separating from the joint body, and to simplify the structure of the joint as a whole to improve manufacturing workability.

It is a pipe joint in which a shaped packing 2 is fitted, and when a pipe body 12 is inserted into the packing 2 and the packing 2 is compressed outward in the radial direction, the outer diameter of the fitting is The dimension D has been enlarged to embed expandable and contractible coil springs 3 and 3a that are respectively locked to locking portions 7 and 7a formed at both ends of the spherical recess 6.

Since it is locked by the locking parts 7, 7a at both ends of the spherical recess 6 of the main body 4, even if a pulling force is applied to the packing 2, the packing 2 will not move.
Their withdrawal and withdrawal will be completely prevented.

以下、本考案の実施例について図面を参照して
説明する。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

のテーパ状である。 In FIG. 1, reference numeral 4 indicates a substantially cylindrical joint body made of one member, and the joint body 4 has a spherical recess 6 formed on the inner peripheral surface 5 at one end thereof, as shown in FIG. ing. Reference numerals 7 and 7a indicate locking portions formed at both ends of the spherical recess 6, respectively.
The inner diameter dimension a is the smallest inside the spherical recess 6. Reference numerals 8 and 8a indicate inner peripheral surfaces located on both outer sides of the locking portions 7 and 7a, and the inner peripheral surfaces 8 and 8a are tapered outward.

Also, one side of each coil spring 3, 3a is exposed from both ends of the packing 2.
本実施例に係る管継手１１の構成部品は以上の
構成からなり、次にその使用方並びに作用につい
て説明する。 The components of the pipe joint 11 according to this embodiment have the above-mentioned configuration, and the usage and operation thereof will be explained next.

装着作業が困難となることは一切ない。 First, the original diameter d of the packing 2 is larger than the inner diameter da of the locking part 7 of the joint body 4;
The diameter d of the packing 2 is the inner diameter of the joint body 4.
The packing 2 is fitted into the spherical recess 6 of the joint body 4 in a compressed state smaller than da, and in the state shown in FIG. 1 after fitting, the packing 2 is restored to a state close to its original diameter d. However, when the packing 2 is compressed to a small diameter when the packing 2 is installed inside the joint body 4, the coil springs 3, 3a inside are also compressed at the same time, so that the presence of the coil springs 3, 3a is reduced. This does not make the work of installing the packing 2 difficult at all.
次に、前記継手に管体を連結させる場合につい
て説明すれば、先ず第４図イに示す如くパツキン
２内に管体１２を挿入させた状態に於いては、前
記パツキン２の全体はその半径方向外方に圧縮さ
れて、その外周面が球面凹部６の内周面に面接触
し、これによつて管体１２が同図ロの如く継手本
体４に対して揺動自在となるのである。 Next, to explain the case where a pipe body is connected to the joint, firstly, when the pipe body 12 is inserted into the packing 2 as shown in FIG. It is compressed outward in the direction, and its outer circumferential surface comes into surface contact with the inner circumferential surface of the spherical recess 6, thereby making the tube body 12 swingable relative to the joint body 4 as shown in FIG. .

ルスプリング３，３ａはその外径寸法Ｄが拡大さ
れて継手本体４の球面凹部６の両端側の内周面に
夫々強固に当接される。 In the above state, the coil springs 3, 3a embedded in the packing 2 are also pressed outward by the tube body 12, so that the coil springs 3, 3a are The diameter dimension D is enlarged, and the joint body 4 is firmly abutted on the inner circumferential surfaces of both ends of the spherical recess 6, respectively.

る。 Therefore, in this state, for example, if a pulling force is generated in the tube body 12 in the direction of arrow B, and a pulling force in the same direction is also applied to the packing 2, one of the coil springs 3 will move against the right end of the spherical recess 6. Since it is locked to the locking portion 7, the packing 2 is completely prevented from being accidentally removed from the spherical recess 6. Similarly, even if a force in the direction opposite to the direction of the arrow B is applied to the packing 2, the other coil spring 3a is engaged with the locking portion 7a, so that the packing 2 is suitably prevented from coming off.

キン２に対して摺動自在に挿通されているか否か
は一切問うものではない。 Furthermore, when the tubular body 12 is slid in the left-right direction, the stopper ring 14 and the stopper 19 provided appropriately on the tubular body 12 are respectively locked to the coil springs 3 and 3a.
This also prevents the tubular body 12 from coming off and sliding beyond a predetermined size. That is, whether the tube body 12 is inserted into the packing 2 in a fixed state or slidably, a pulling force acts on the packing 2, but the coil springs 3, 3a installed in the packing 2 In any of the above cases, the sealing member 2 acts to abut and lock the locking portions 7, 7a of the joint body 4 to prevent the packing 2 from coming off. Therefore, in the present invention, there is no question as to whether or not the tube body 12 is slidably inserted into the packing 2 or not.

至つた。(Effects of the invention) As described above, the present invention embeds expandable and contractible coil springs in both ends of the packing, and when the tube is inserted into the packing, the diameter of the coil spring expands. Since the coil spring is configured to be locked to the locking portions at both ends of the spherical concave portion of the joint body, the gasket can be easily removed when a pulling force is applied, unlike a conventional gasket made of only an elastic member. There is no possibility that the gasket will be compressed and deformed and come off from the joint body, and the installed state of the gasket can be reliably maintained by the engagement between the coil spring and the locking part of the spherical recess, so that it is always in the proper state. We have achieved the special effect of being able to connect the tubes.

できるという顕著な効果をも有するに至つた。 Moreover, when the packing is inserted into the spherical recess of the joint body and the coil spring is simultaneously reduced and deformed, the coil spring does not interfere with the fitting of the fitting. However, it has also had the remarkable effect of making the fitting work easier.
従つて、本考案によれば、従来では解決できな

なる実益をも有する。 Furthermore, as mentioned above, the present invention allows the entire packing to be reduced and deformed together with the coil spring so that it can be fitted into the spherical recess of the joint body, thereby constructing the joint body into a single piece. Therefore, the number of parts in the entire joint is small, and it has excellent manufacturability, and has the great practical benefit of being able to reduce manufacturing costs.
