個縫隙22，22之3字形之鍵構件24所構成，將鍵構件24之 相對向之卡止部24a，24b之對向部間尺寸，設定於稍小於 配管21之直徑同時，於此卡止部24a，24b之前端部，形成 一於釘入初期抵觸於配管21之表面且隨著釘入而嵌入配管 21表面之錐形部25者已為公知。 如依這種構成之配管接頭裝置，可將連接對象之配管 21插入接頭本體23之同時，將鍵構件24 , 24嵌入接頭本體 23之縫隙22，22，然後用鐵槌重覆衝擊，藉由鍵構件24之 錐形部25，25使前述配管21之表面局部地壓縮變形，一面 使錐形部25 , 25嵌入其壓縮變形部，一面使卡止部24a， 24a卡止於其嵌入後之面部，藉此來達成配管21與前述接 頭本體23之連接。 然而，於這種構成之配管接頭裝置，由於用來壓縮變 形配管面面之鍵構件24係形成η字形狀，所Μ鍵之打進力 被分散於二傾卡止部24a，24b，在鍵構件24之打進時，必 需大揮鐵槌重覆強打鍵構件24,除了被迫做強力勞動Μ外 尚有鍵構件24之打進需花費時間等問題。 (請先閱讀背面之注意事項再填寫本頁) -裝_ 訂. 線 1 in —1- «ΙΊΙ · 本紙張尺度適用中國國家標準（CNS ) A4規格（210X297公釐） 4 A7 B7 經濟部中央標準局員工消費合作社印製 五、發明説明（ 又，隨著砸入，卡止部24a，24a，互相容易任意擴大 ，因此為了該卡止部24a，24b之基部側強度之提高，而必 需要把鍵構件24作成寬廣之形狀，但這麼一來鍵構件24便 從配管21之表面大幅突出，而有被服被釣住或傷及身體等 之危險性。而且，由於在強打鍵構件24時配管21之支持構 件將受到其強打份兒之打進衝擊，所Μ存在著必須將該支 持構件作成堅固構造等題題，更且，為了大揮鐵槌打進鍵 構件24,而在管周圍需要廣闊之空間，所Μ如配管空間狹 窄，配管輻湊的話，有配管之作業變成非常困難的問題。 尤其是，在打進鍵構件24時，將鍵構件24直線狀地打 進去，使之嵌定保持於配管之事乃為極重要之工作，可是 如果誤打鍵構件24之打進處，例如打到鍵構件24之上端隅 角部的話，下部側之卡止部24b則變成從縫隙22跑出，使 得僅由上部側之卡止部24a使配管21壓縮變形。在此情況 下，配管21—有振動，鍵構件24即隨著滑落，從而造成很 大的由配管21之致命脫落所引起之危險性，為此對鍵構件 24之打進要求相當之熟練度。 〔發明之概要〕 本發明係鑑於上述實情而創作者，其目的係在於提供 一種不需要熟練，而可用輕力，因此*不需大揮鐵槌，可 迅速且確實地連接配管之配管接頭裝置。 爲了達成上述目的，本發明所取之技術方段係如下。 即，本發明之配管接頭裝置，係由一於插入配管表面

於前述孔徑之直徑）所構成之卡止部8之前端側，形成有 一Μ揷入前述透孔7之狀態抵觸於配管2表面之截頭圓錐 形之錐形部9同畤，於此錐形部9前端連縉形成有螺紋部 2，並將前述卡止部8與錐形部9之合計長度尺寸，設定 於稍小於前逑鼓出部4a之長度尺寸。 由這種構成之配管接頭裝置1所成之配管2與接頭本 體4之連接，係按照以下之步驟行之。 經濟部中央標準局員工消費合作社印製 首先，藉配管2之端部通過透孔7及0環a，將此配 管2插入接頭本體4之插入管部3，至該配管2之端部位 置於位置限制構件6之附近，或者，抵觸於該位置限制構 件6，使此配管2之表面之一部分面臨於接頭本體4之透 孔7 (請參照第2圖右側）。 此配管2之插入是否達到所規定者之判斷，乃靠感覺 行之。且，為了期待插入之正確度，最好，考慮配管2之 規定插入尺寸，在配管表面例如施K彩色塗料之標記，預

入透孔7成拘束狀態之鍵構件5之錐形部9所局部地壓縮 變形，藉此，使錐形部9深入其壓縮變形部。 然後，重覆叩擊該鍵構件5，藉此使前逑錐形部9逐 漸深入配管表面之壓縮變形部同時，使卡止部8卡止於其 深入後之面部，使得前述配管2Κ止拔之狀態連結固定於 接頭本體4，其後，視其需要而將螺母D螺定於螺紋部d ，以謀求鍵構件5之止拔，藉此完成配管2之對於接頭本 體4之插入連接。 依照上述之構成，雖在令配管之表面局部地壓縮變形 ，使卡止部卡止於其深人面部方面，與習知之藉3字形鍵 構件來連接配管之形態並無不同，但由於打擊對象之鍵構 件5爲拘束在透孔7内之一支單體物，所Μ在鍵構件5之 打進時，可使打擊力集中於該一支之鍵構件5，即使沒有 大揮鐵槌強打鍵構件5，也可藉錐形部9使配管2之表面 局部地壓縮變形。 因此，如依照這種構成之配管接頭裝置1的話，並不 需要熟練任誰都可簡單且迅速地，用輕力來進行配管2之 對於接頭本體4之連接，同時並不需要大揮鐵槌，所Μ即 使配管空間狹窄或配管輻湊（集中於一處），也可輕易進 (請先·Η讀背面之注意事項再填寫本頁) -裝. 訂 « in In . 本紙張尺度適用中國國家標準（CNS ) Α4規格（210Χ297公釐） 9 五、發明説明（8 ) A7 B7 經濟部中央標準局員工消費合作社印製 樣卻為相同，故省略其連接態樣之重覆說明。其次，根據 第8圖，說明有關第三實施例之配管接頭裝置1。此配管 接頭裝置1，係於較之接頭本體4中之透孔便向内側之揷 入管部3之内部，設有密封配管2用之0環a，一方面在 前述接頭本體4之内部一體連設有一從内倒支持配管2端 部之型心14上具有特激。該型心14係形成對插入管部成同 心圓狀；該型心14之外面雖與插入管部3之內面呈並行之 圓筒狀，但型心14之内面卻形成錐形狀K便盡可能地減少 對流體之阻力。其他構成則與上述第一實施例相同，故省 略說明。 如依此構成，由於將配管2插入接頭本體4之插入管 部3中，於此狀態，藉由型心14從內側支持配管2之端部 ，所Μ將鍵構件5打進透孔7使配管2局部地壓縮變形時 ，即使在位置於鍵構件5兩俩之管壁部分多少產生有應變 ，也可利用型心14來阻止位置於0環a附近之管壁之變形 ，可使〇環a與配管2外面之接觸穩定。 即，當將鍵構件5打進接頭本體4之透孔7，使配管 2局部地壓縮變形時，如僅只舆管壁之鍵構件5接連之部 位變形的話，倒沒有什麽問題，可是實際上多在位置於鍵 構件5兩侧方之管壁部分產生應變。因此，如透孔7與0 環a之間隔過窄的話，隨鍵構件5之打進而產生之管壁之 應變則及於0環a位置，0環a與配管2外面之接觸變鬆 ，從而使藉助於0環a之密封性能降低，最後可能引起漏

件5之打進而引起之管壁應變之影罌，但此時，由於透孔 7與0環a之間隔變大而接頭本體4中之揷入管部3之長 度變長，配管接頭裝置1之尺寸於是拉長此變長之部分。 在此方面，如第8圖所示，只要在接頭本體4之内部 設有一從内侧支持配管2之端部之型心14 ,即使將透孔7 與0環a之間隔設定得狹窄，0環a也不受随著鍵構件5 之打進而引起之管壁應變之影轡，不需拉長配管接頭裝置 1之尺寸，也可確保高密封性能。 又，第8圖雖圖示跟第1圖〜第3圖所示者同一型式 (使用斷面爲圓形之鍵構件5之配管接頭裝置1)作為接 頭4和鍵構件5，但就择頭本體4和鍵構件5而言，不用 說可使用跟第4圖〜第7圖所示之第二實施例同一之型式 者。 其次，根據第9圖〜第11屬，說明第四實施例之有關 配管接頭裝置1。此配管接頭裝置1，係於較之接頭本體 4中之透孔7更內側之前述接頭本體4内部，設有一壓接

3間。型心式墊圈15之筒狀部分15b之外面雖可形成與插 入管部3之內面並行之圓筒狀，但本實施例，一如第10圖 所示，乃讓筒狀部分15b向直徑方向外方翹曲，使筒狀部 分之前端部強勁且確實地接觸於配管2之内面。又，於第 9圖〜第11圖中，雖圖示跟第1圖〜第3圖所示之第一實 施例同一型式（使用斷面為圓形之鍵構件5的配管接頭裝 置1)作為接頭本件4和鍵構件5,但不同說也可使用跟

Description of the Invention (1) [Field of Invention] The present invention relates to a joint device for various pipes such as steel pipes, non-embroidered concrete pipes, other copper pipes, or synthetic resin. [Explanation of the Known Technology] As for such a piping joint device, it is known as disclosed in Japanese Patent Application Publication No. 6291 of the Heisei 5 Years; that is, as shown in FIG. The two slit openings on the surface of the piping 21 are formed by the joint body 23 formed on both sides of the center of the pipe axis, and a key member 24 which is fixed in the shape of the two gaps 22 and 22, and the key members 24 are opposed to each other. The dimensions of the opposing portions of the locking portions 24a, 24b are set to be slightly smaller than the diameter of the piping 21. At the same time, the front ends of the locking portions 24a, 24b form a contact with the surface of the piping 21 at the initial stage of nailing and follow A tapered portion 25 that is inserted into the surface of the pipe 21 by nailing is known. According to the piping joint device configured in this way, while inserting the pipe 21 to be connected into the joint body 23, the key members 24, 24 are inserted into the gaps 22 and 22 of the joint body 23, and then the impact is repeated with an iron hammer. The tapered portions 25 and 25 of the key member 24 partially compress and deform the surface of the piping 21 described above, while the tapered portions 25 and 25 are fitted into the compression-deformed portion, and the locking portions 24a and 24a are locked after the fitting. With the face, the connection between the piping 21 and the joint body 23 is achieved. However, in the piping joint device of this configuration, since the key member 24 for compressing and deforming the piping surface is formed into an η shape, the driving force of the M key is dispersed in the two-tilt locking portions 24a, 24b. When driving in the component 24, a large hammer must be used to repeat the strong keying component 24. In addition to the forced labor M, there are problems such as the time required for the key component 24 to advance.

Description of the invention (Also, the locking portions 24a, 24a can easily expand each other arbitrarily as they are broken in. Therefore, it is necessary to improve the strength of the base side of the locking portions 24a, 24b. The key member 24 is formed in a wide shape, but in this way, the key member 24 protrudes greatly from the surface of the piping 21, and there is a danger of being caught by fishing or hurting the body. Moreover, the piping is performed when the key member 24 is strongly hit. The support member of 21 will be impacted by the impact of its strong members. Therefore, there are problems such as the need to make the support member a solid structure. In addition, in order to enter the key member 24 with a large hammer, it is necessary to surround the tube. For a wide space, if the piping space is narrow and the piping is spliced, there is a problem that the piping operation becomes very difficult. In particular, when the key member 24 is driven, the key member 24 is driven straight in to fix it. Holding the piping is an extremely important task. However, if the entry of the key member 24 is accidentally hit, for example, if it hits the upper corner of the key member 24, the locking portion 24b on the lower side will run out of the gap 22. So that the piping 21 is compressed and deformed only by the locking portion 24a on the upper side. In this case, the piping 21 vibrates, and the key member 24 slides down, resulting in a large amount caused by the fatal drop of the piping 21. For this reason, the proficiency required for driving the key member 24 is considerable. [Summary of the Invention] The present invention was created in view of the above facts, and its purpose is to provide a light force that does not require proficiency, so * The piping joint device for piping can be quickly and surely connected without the need for a big hammer. In order to achieve the above purpose, the technical section taken by the present invention is as follows. That is, the piping joint device of the present invention is made by inserting piping.

Description of the invention (5) Inside, a setting is used to restrict the aforementioned piping 2 At the same time as the position restricting member 6 of the insertion position, a groove b for inserting and holding a seal is formed on both sides of the position restricting member 6 respectively, and a ring b is inserted into the pipe 2; Further toward the outer surface of the pipe end side, a semi-circular bulging portion 4 orthogonal to the center direction of the tube axis is continuously provided; here, the bulging portion 4a forms a circular through hole 7 which is inserted in the connection direction facing The surface of the aforementioned pipe 2 inserted into the pipe portion 3. The eight front key members 5 are used to describe the through holes 7; they are formed by a circular pin (having a large diameter head C larger than the aforementioned through holes and having a diameter corresponding to that of the through hole). The front end side of the locking portion 8 constituted by the diameter of the aforementioned hole is formed with a truncated conical cone that is in a state of being inserted into the through hole 7 and abutting against the surface of the pipe 2 9 is the same, a threaded portion 2 is formed at the front end of the tapered portion 9 in succession, and the total length of the locking portion 8 and the tapered portion 9 is set to be slightly smaller than the length of the front raised portion 4a. The connection between the piping 2 formed by the piping joint device 1 and the joint body 4 is performed in accordance with the following steps. Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs First, the end of the piping 2 is passed through a through hole 7 and 0 rings a, insert this pipe 2 into the insertion pipe portion 3 of the joint body 4, until the end portion of the pipe 2 is placed near the position restriction member 6, or, abut the position restriction member 6 to make this pipe 2 Part of the surface faces the through hole 7 of the joint body 4 (refer to the right side of FIG. 2). The judgment of whether the insertion of the pipe 2 reaches the prescribed one is made by feeling. And, in order to expect the correctness of the insertion, It is best to consider the specified insertion size of piping 2 and apply K color paint on the surface of the piping. The paper size is pre-applied to the Chinese National Standard (CNS) A4 (210X297 mm). 8 Α7 Β7 Employees of Zhongli Standards Bureau, Ministry of Economic Affairs Consumer cooperatives Printed 5. Description of the invention (6) First, make a mark so that the piping 2 is inserted into the joint body 4 according to the specified size, and the mark can be confirmed with a visual stool through the through hole 7 of the joint body 4. Next, the key member 5 is inserted into the foregoing The through hole 7 is a state in which the tapered portion 9 is in contact with the surface of the pipe 2 and the hammer member 5 is used to hit the key member 5. In this way, the pipe 2 is inserted into the through hole 7 as the key member 5 is hit. The conical portion 9 of the key member 5 in the restrained state is partially compressed and deformed, thereby causing the tapered portion 9 to penetrate into its compression deformed portion. Then, the key member 5 is repeatedly tapped, thereby tapering the front palate. The portion 9 gradually penetrates the compressive deformation portion of the piping surface, and at the same time, the locking portion 8 is locked on the face after the penetration, so that the piping 2K is pulled out and fixed to the joint body 4, and then, if necessary, the nut The D screw is fixed to the threaded portion d to prevent the key member 5 from being pulled out, thereby completing the insertion connection of the pipe 2 to the joint body 4. According to the above structure, although the surface of the piping is locally compressed and deformed, and the locking portion is locked on its deep human face, it is not different from the conventional form of connecting the piping by a 3-shaped key member, but because of the target of strike The key member 5 is a single body confined in the through hole 7, so when the key member 5 is driven in, the striking force can be concentrated on the key member 5 even if there is no strong hammer. The key member 5 may be partially compressed and deformed by the tapered portion 9. Therefore, if the piping joint device 1 according to this structure is used, it is not necessary for anyone to be able to simply and quickly connect the piping 2 to the joint body 4 with light force, and at the same time, a large hammer is not required. , So even if the piping space is narrow or the piping is spliced (concentrated in one place), it can be easily entered (please read the notes on the back before filling out this page)-binding.

Description of the invention (8) A7 B7 The printed samples of the staff consumer cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs are the same, so the repeated descriptions of the connection patterns are omitted. Next, a piping joint device 1 according to a third embodiment will be described with reference to Fig. 8. The piping joint device 1 is located inside the pipe section 3 and penetrates inwardly than the through hole in the joint body 4. It is provided with a 0 ring a for sealing the piping 2. On the one hand, it is integrally connected with the inside of the joint body 4. The core 14 provided with an end portion supporting the pipe 2 from the inside has a special exciter. The core 14 is formed into a concentric circle shape with respect to the insertion tube portion. Although the outer surface of the core 14 is in a cylindrical shape parallel to the inner surface of the insertion tube portion 3, the inner surface of the core 14 has a tapered shape. It is possible to reduce the resistance to the fluid. The other configurations are the same as those of the first embodiment described above, so the description will be omitted. With this configuration, since the pipe 2 is inserted into the insertion pipe portion 3 of the joint body 4, in this state, the core portion 14 supports the end portion of the pipe 2 from the inside, so that the key member 5 is driven into the through hole 7 so that When the piping 2 is partially compressed and deformed, even if there is some strain in the pipe wall portions located at the key member 5, the core 14 can be used to prevent the deformation of the pipe wall located near the 0 ring a, so that the 0 ring a. The contact with the outside of piping 2 is stable. That is, when the key member 5 is driven into the through hole 7 of the joint body 4 and the pipe 2 is partially compressed and deformed, if only the successive parts of the key member 5 of the pipe wall are deformed, there is no problem, but it is actually many Strain is generated in the pipe wall portions located on both sides of the key member 5. Therefore, if the distance between the through hole 7 and the 0 ring a is too narrow, the strain of the pipe wall caused by the hitting of the key member 5 is at the position of the 0 ring a, and the contact between the 0 ring a and the outside of the pipe 2 becomes loose, so that The sealing performance by the 0 ring a is reduced, and finally water leakage may be caused. ----.-- J ---- --install ----- one——order ----- ^-j line 1 (Please read the precautions on the back before filling this page) This paper size applies China National Standard (CNS) A4 specification (210X 297 mm) _ 11 11 V. Description of invention (9) A7 B7 The Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs printed a statement about such unsuitable avoidance countermeasures, or permitted the examination Leave a sufficient gap between the through-hole 7 and the 0 ring a so that the 0-ring 5 is not affected by the strain of the pipe wall caused by the hitting of the key member 5. However, at this time, the through-hole 7 and the 0 ring a The interval of a becomes larger and the length of the pipe-in pipe portion 3 in the joint body 4 becomes longer, so that the size of the pipe joint device 1 becomes longer. In this regard, as shown in FIG. 8, as long as a core 14 is provided inside the joint body 4 to support the end of the pipe 2 from the inside, even if the interval between the through hole 7 and the 0 ring a is set to be narrow, the 0 ring a is not affected by the strain of the pipe wall caused by the hitting of the key member 5, and it is not necessary to lengthen the size of the pipe joint device 1, and high sealing performance can be ensured. Fig. 8 shows the same type as the one shown in Figs. 1 to 3 (the piping joint device 1 using the key member 5 having a circular cross section) as the joint 4 and the key member 5, but the head is selected. For the body 4 and the key member 5, needless to say, the same type as the second embodiment shown in Figs. 4 to 7 can be used. Next, the piping joint device 1 according to the fourth embodiment will be described with reference to Figs. 9 to 11. This piping joint device 1 is located inside the aforementioned joint body 4 which is more inside than the through hole 7 in the joint body 4, and is provided with a core washer 15 crimped to the inner surface of the end portion of the piping 2 with special features. The core washer 15 is made of an elastic material such as rubber or synthetic resin. This washer 15 includes: a ring portion 15a, which is embedded with a positioning ring groove 16 formed on the inner surface of the joint body 4; and a cylindrical portion 15b, which is integrally connected to the axial direction two from the inside of the ring portion 15a. Among them, the cylindrical portion 15b is elastically in contact with the inner surface of the pipe 2, thereby exerting the sealing function.

Description of Invention (l〇) Since a 0 ring a connected to the outside of the piping 2 and a core washer 15 connected to the inside of the piping 2 can be used to exert the second-layer sealing function, high sealing performance can be ensured. Further, it is preferable that the inner surface side of the end portion of the pipe 2 be sloped in advance so that the pipe 2 can be smoothly inserted between the core washer 15 and the insertion pipe portion 3 of the joint 4. Although the outer surface of the cylindrical portion 15b of the core washer 15 can be formed in a cylindrical shape parallel to the inner surface of the insertion tube portion 3, as shown in FIG. 10, the cylindrical portion 15b is made to have a diameter Warping in the outward direction makes the front end of the tubular portion strongly and surely contact the inner surface of the pipe 2. In addition, in FIGS. 9 to 11, the same type as the first embodiment shown in FIGS. 1 to 3 is shown (a piping joint device 1 of a key member 5 having a circular cross section is used) as the illustration. The joint body 4 and the key member 5 are different, but the same type as the second embodiment shown in FIGS. 4 to 7 may be used. Next, a piping joint device 1 according to a fifth embodiment will be described with reference to Fig. 12. This piping joint device 1 is an improved version of the piping joint device 1 of the second embodiment described above. As shown in FIG. 13, for example, the outside of the piping inserted on the end side is honed by a sander and processed into The pipe 2 of the tapered tapered surface portion 2a, or a pipe 2 which is processed into the tapered tapered surface portion 2a by using an extruder or the like as shown in FIG. 14 is used as a connection target. Specifically, a ring-shaped recessed portion f is formed in the vicinity of the position-limiting member 6 of the joint body 4, and a conical portion is formed on the ring-shaped recessed portion f so as to correspond to the tapered tapered surface portion 2a of the pipe 2 described above.

Description of the invention (11) Move in the direction of entry, and a seal is formed between the piping 2 and the sealing mechanism 13; on the one hand, as shown in Figure 15 As shown, as the key member 5, a locking member 11 having a tapered portion 9 and a locking portion 8 is used, which faces the hole shaft core of the through hole 7 and is slightly withdrawn toward the pipe shaft core of the pipe 2. Thereby, the pipe 2 is moved in the insertion direction as the key structure 5 is struck. That is, it is made on the inclined surface of the locking member 11 (the tapered portion 9 and the locking portion 8) to generate a thrust force that can move the pipe 2 with the key member 5 and move toward the core of the pipe shaft. A tapered contact seal is formed between the tapered surface portion 2a of the aforementioned pipe 2 and the tapered surface S of the sealing mechanism 13. According to the above configuration, a part of the driving force of the key member can be converted into the pipe 2 The tapered tapered surface portion 2a is pressed in the direction of the tapered surface S of the sealing mechanism 13, so that the affinity between the pipe 2 and the sealing mechanism 13 can be improved, and high sealing performance can be ensured. In the above-mentioned embodiment, although a gasket is used as the sealing mechanism 13, the annular recessed portion f is not formed. Instead, a conical surface S is formed in the joint body 4 itself as a sealing mechanism. As the pipe 2 moves in the insertion direction, It is also possible to form a seal using a tapered metal contact between the tapered surface portion 2a and the tapered surface S of the pipe 2. At this time, it can be applied between the surfaces contacted by gold, such as a liquid sealing material .

That is, the key member 5 shown in Fig. 17 is a part in which the key member 5 used in the second embodiment or the fifth embodiment is partially changed. According to the second embodiment or the fifth embodiment, as shown in FIG. 6, the ridge line of the locking portion 8 which is locked on the pipe surface formed by the tapered portion 9 and penetrates into the face is formed with the key body 10. The number of surfaces (bottom surface) is parallel, but the ridge line of the locking portion 8 on the key member 5 side shown in FIG. 17 forms a tapered portion S3 with a gentle slope, so that the locking portion will be followed by the _ member 5 Go deeper into the piping surface that penetrates into the face. When the key member shown in FIG. 17 is used in the second embodiment, the locking member 11 (the tapered portion 9 and the locking portion 8) is provided in parallel with the longitudinal direction of the key body 10, and In the fifth embodiment, the locking member 11 (the tapered portion 9 and the locking portion 8) is inclined to face the key body 10 in a long direction as shown in FIG. 12. In either case, the tapered portion S3 formed at a gentle slope of the ridge line of the locking portion 8 can be extended to the front end of the locking member 11 so that the tapered portion 9 and the ridge line formed at the locking portion 8 are relaxed. The inclined tapered portion S3 has the same gradient. On the one hand, the key member 18 shown in FIG. 18 is a part of the key member used for the piping joint device 1 of the fifth embodiment is changed by M, so that the locking portion 8 has a deeper function.

The front end of the key body 10 is made to protrude from the through hole 7, and the key member 5 is pulled out by the bending deformation of the protruding portion 10a. As shown in Fig. 17 and Fig. 18, since the deformation of the pipe wall of the piping 2 progresses slowly with the hitting of the key member, the connection of the piping 2 to the joint body 4 can be performed with more force. . In addition, according to each of the above-mentioned embodiments, although a form in which one key member 5 is driven into one connection object is adopted, a plurality of through holes 7 are formed at a predetermined interval in the circumferential direction of the joint body 4 A connection form in which the key member 5 is driven into each of the through holes 7 to compress and deform the piping 2 at a plurality of locations is also possible. In addition, since the above-mentioned key member is confined inside the through-hole 7 and is tightly held between the surface of the pipe 2 and the through-hole 7 which are compressed and deformed, it is not necessary to stop the nut D or the bending of the protruding portion 10a.

For example, according to the structure of the scope of application patents Nos. 1 to 6, the surface of the key structure piping is partially compressed and deformed, and when a key member latching part is locked in this compression deformed part, the key of the object to be struck is taken. The component is made into a single body confined in the through hole, so that the striking force can be concentrated on the key component. Therefore, no strong hammer is required to hit the key component, so no proficiency is required.
