[Prior Art] The use of the combination pipe is quite extensive and is common in pipe fittings such as daily product frames and frames. The existing combined tube, usually the inner tube is inserted into the outer tube, and the machine f limits the total length of the combined tube to no change. However, the two tubes are the same as the circular tube wall, which is easy to cause rotation. It is not eliminated by the card engine mechanism. For the user, the hidden factor belonging to the accident is not to be careless. Here, the author of this essay explores the problem of cutting technology. =,: Years of experience in R&D and manufacturing of related industries, actively seeking for the way, finally succeeded in developing a set of reforms to improve Xi (10). [New content] In order to solve the above problems, the applicant uses a hand with non-circular pipe fittings: 'The hidden danger of the straight inner pipe rotating relative to the outer pipe, achieving the purpose of strengthening the structure, smoothing the movement and lifting the load, etc. The present invention provides a combined tube structure, the good '疋 is composed of an inner tube inserted-outer tube-combined tube, the inner::b; the wheel f is non-circular' having a plurality of holes penetrating the wall of the tube, and the shape of the outer wall of the outer panel It conforms to the shape of the inner tube. The inner tube can be reciprocated along the length of the tube but cannot rotate relative to the outer tube. 3 M396350 The inner and outer tubes can be elliptical, semi-circular, square, and six. One of the angles or other shapes. In addition, the shape of the hole of the inner tube penetrating the wall of the tube may be one of a hexagonal hole, an elongated hole, a round hole, a square hole or other function shape for the snap mechanism to be engaged. The techniques, means and functions thereof are as follows, and the following examples are given in detail with reference to the drawings. It is believed that the above-mentioned objects, structures and features of the present invention can be obtained by - deep and specific [embodiments] The related embodiments are described in detail.
明參閱第1、2圖，是由一内管2〇插入一外管 3〇合稱為-組合f 10。該内管2〇外表呈擴圓形狀並 在:壁貫穿複數六角孔22，而外管％内壁形成吻合 /内管20外表的形狀，限制内管2〇沿著管長方向作往 復運動，進而延長或縮減組合管1〇的總長度。這些 六角孔22彼此隔著相同的距離，供—卡掣機構 料㈡洞中’維持組合f W 長度。 又丨匕说… 圖面中，該内管20與外管3〇為管徑不一的橢圓 形管體，無論如何扭動，皆不能讓内# 2〇才目對外管 3〇旋轉，故組合管10整體結構強度相當 提昇負荷程度。 〃相對 根據上述組合管10的結構特性，得以衍生以 的實施例。 ’ 譬如第3、4圖緣製的組合管1〇，同樣是讓内管 4 M396350 40插入外管5〇尹。 50為管徑* —的& 處在於··該内管40與外管 .1 、颌似半圓形管體，並在兩管各自形 成一平面部41、5丨，、士 a τ θ ^ 51廷些平面部41、5!彼此靠攏， 止内g 40相對外誉士>古由. 貫穿若干長形 ^轉。在内管40平面部41 距離，供卡掣m 42彼此隔著相同的 :挲機構卡入而維持組合管10總長度。 外管;〇如為第二:6圖所示，該組合管10的内管60與Referring to Figures 1 and 2, an inner tube 2〇 is inserted into an outer tube 3, which is called a combination f 10 . The inner tube 2 has a rounded outer shape and the wall penetrates the plurality of hexagonal holes 22, and the inner wall of the outer tube forms the shape of the outer surface of the inner tube 20, restricting the inner tube 2 to reciprocate along the length of the tube, thereby extending Or reduce the total length of the combined tube 1〇. These hexagonal holes 22 are separated from each other by the same distance, and the length of the combination f W is maintained in the "cavity mechanism" (2) hole. In other words, in the figure, the inner tube 20 and the outer tube 3 are elliptical tubes of different diameters, and no matter how they are twisted, the inner tube 2 can not be rotated by the outer tube. The overall structural strength of the composite pipe 10 considerably increases the degree of load. 〃In contrast to the structural characteristics of the above-described composite pipe 10, an embodiment derived therefrom is derived. For example, the combination tube of the 3rd and 4th sheets is 1〇, and the inner tube 4 M396350 40 is also inserted into the outer tube 5〇. 50 is the diameter of the tube * - the inner tube 40 and the outer tube .1, the jaw is a semi-circular tube body, and each of the two tubes forms a flat portion 41, 5 丨, 士 a τ θ ^ 51 some flat parts 41, 5! Close to each other, stop inside g 40 relative outside the reputation of the ancients. Through a number of long form ^ turn. At the distance of the flat portion 41 of the inner tube 40, the cassettes 42 are separated from each other by the same: the mechanism is engaged to maintain the total length of the combined tube 10. The outer tube; as shown in the second: Figure 6, the inner tube 60 of the combined tube 10 is

One of the inner tubes 6 of the cowpea penetrates a plurality of circular holes 62 which are separated by the same distance, and the total length of the combined tube 1〇 is maintained by the action of the card engine. Then, the seventh and eighth figures are seen. The inner tube 8 of the combined tube 1 is a hexagonal tube having a diameter of *, and the inner tube 80 is rotated relative to the outer tube 90 by the opposing tube wall. One of the inner tubes 8 is: a wall spans through a plurality of square holes 82, and the total length of the combined tubes 10 is determined by the snap mechanism engaging the holes.
最後看到第9圖的組合管10，與第3、4圖實施 例相似，1樣是讓内管4〇插入外管5〇中。差異處在 於：該外管5G為大管徑的圓形管體，套在半圓形的 内管40外部。 根據上述說明，本實施例的組合管具備以下優 點： ’、 内^外管彎曲為非圓形的管壁，利用彎折角落強 化官件結構，相對提昇組合管整體強度，兼具兩 管往復運動的引導作用，使組合管長度伸縮動作. 順暢。 5 二、組合管整體負荷程度，因為管壁結構性強化而 所提昇。 ^上述實施例僅為說明本創作，非為限制本創作。 熟習此技藝者從上述實施例衍生之各種變化、修改與 應用均在本創作之範B壽内。 【圖式簡單說明】 第1圖是立體圖，表現本創作組合管第一較佳垂 施例的組裳情形。 只 第2圖是剖視圖，表現第i圖橢圓形組合管有關 内、外管結合部位的具體情形。 第3圖是立體圖，表現本創作組合管第二較佳恭 施例的組裝情形。 只 第4圖是剖視圖，表現第3圖類似半圓形組合管 有關内、外管結合部位的具體情形。 第5圖疋立體圖，表現本創作組合管第三較佳每 施例的組裝情形。 貝 第6圖是剖視圖，表現第5圖四方形組合管有關 内、外管結合部位的具體情形。 第7圖疋立體圖，表現本創作組合管第四較佳每 施例的組裝情形。 只 第8圖是剖視圖，表現第7圖六角形組合管有關 内、外管結合部位的具體情形。 第9圖是剖視圖，表現本創作組合管第五較佳實 施例有關内、外管結合部位的具體情形。 貝 M396350 【主要元件符號說明】 組合管10 内管 20、40、60、80 六角孔22 外管 30、50、70、90 平面部41、51 長形孔42 圓孔62 方孔82Finally, the composite tube 10 of Fig. 9 is seen, similar to the embodiment of Figs. 3 and 4, in which the inner tube 4〇 is inserted into the outer tube 5〇. The difference is that the outer tube 5G is a circular tube having a large diameter and is sleeved outside the semicircular inner tube 40. According to the above description, the combined tube of the present embodiment has the following advantages: ', the inner and outer tubes are bent into a non-circular wall, and the bent corner is used to strengthen the official structure, and the overall strength of the combined tube is relatively increased, and both tubes are reciprocated. The guiding effect of the movement makes the length of the combined tube telescopic. Smooth. 5 2. The overall load level of the combined pipe is enhanced by the structural strengthening of the pipe wall.
