Description

Universal joint for connecting liquid piping

本設計係關於一種液體配管接合用之萬向接頭。 This design is about a universal joint for liquid piping joints.

後視圖與前視圖對稱，故省略後視圖。 The rear view is symmetrical to the front view, so the rear view is omitted.

參考立體圖1、2表示第一和第二直管部1和5中的一個或第一和第二直管部1和5中的任何一個的自由端部分20相對於相反端可以旋轉或擺動的大小和廣度的情況。 With reference to the perspective views 1, 2 show that one of the first and second straight pipe portions 1 and 5 or the free end portion 20 of any one of the first and second straight pipe portions 1 and 5 can rotate or swing relative to the opposite end The size and breadth of the situation.

參考剖面圖是沿著立體圖中的A-A'剖面線的中心垂直剖面圖，其中外和內裝配部3和7的外和內半球體2和6的第一和第二直管部1和5的中心軸線Z1和Z2在基本平面S中彼此分別設置成直角(90°)，基本平面S由包括上述中心軸線Z1和Z2形成。而上述這種情況稱為基本情況。 The reference cross-sectional view is a central vertical cross-sectional view along the AA' section line in the perspective view, in which the outer and inner hemispheres 2 and 6 of the outer and inner fitting portions 3 and 7 and the first and second straight pipe portions 1 and 6 The central axes Z1 and Z2 of 5 are respectively set at right angles (90°) to each other in the basic plane S, which is formed by including the above-mentioned central axes Z1 and Z2. The above situation is called the basic situation.

另一方面，在參考剖面圖中，例如，內裝配部7的內半球體6的第二直管部5相對於球心P可旋轉地移動，如沿著基本平面S的箭頭線L所示，並且第一直管部1保持固定狀態。 On the other hand, in the reference cross-sectional view, for example, the second straight pipe portion 5 of the inner hemisphere 6 of the inner fitting portion 7 is rotatably movable relative to the center P, as shown by the arrow line L along the basic plane S , And the first straight pipe portion 1 is kept in a fixed state.

在這種情況下，假設當第二直管部5沿箭頭線L移動到參考剖面圖中至多右手側部分時，並且第一直管部1處於固定狀態，則第一和第二直管部1和5的中心軸線Z1和Z2'之間的夾角約為80°，而上述這種狀態稱為第一情況。 In this case, it is assumed that when the second straight pipe portion 5 moves along the arrow line L to the reference cross-sectional view When the right-hand side part is at most, and the first straight pipe portion 1 is in a fixed state, the included angle between the central axes Z1 and Z2' of the first and second straight pipe portions 1 and 5 is about 80°, and the above-mentioned The state is called the first situation.

另一方面，假設當第二直管部5沿箭頭線L移動到參考剖面圖中至多左手側部分時，並且第一直管部1處於固定狀態，則第一和第二直管部1和5的中心軸線Z1和Z2'之間的夾角約為120°，而上述這種狀態稱為第二情況。 On the other hand, assuming that when the second straight pipe portion 5 moves along the arrow line L to at most the left-hand part in the reference cross-sectional view, and the first straight pipe portion 1 is in a fixed state, the first and second straight pipe portions 1 and The angle between the central axis Z1 and Z2' of 5 is about 120°, and this state is called the second case.

參考立體圖1示出了在第一情況下的配置，其中如圓形允許線B所示第二直管部5以360°的角度，沿著耦接環10的邊緣圓周在與上述基本平面S垂直的單獨的表面T上樞轉，並且保持第一直管部1被固定。 1 shows the configuration in the first case, as shown by the circular allowable line B, the second straight pipe portion 5 is at an angle of 360°, along the edge circumference of the coupling ring 10, in line with the above-mentioned basic plane S The vertical single surface T pivots and keeps the first straight pipe portion 1 fixed.

因此，參考立體圖1以虛線示出了在這第一情況下第二直管部5的自由端部分20的位置可以變化多大和多廣。 Therefore, referring to the perspective view 1, it is shown in dotted lines how much and how wide the position of the free end portion 20 of the second straight pipe portion 5 can vary in this first case.

請注意，參考立體圖1和參考立體圖2中，虛線(-----)表示移動到與初始位置(由實線所示)不同的位置的第二直管部5的相對可見的外部配置。而雙虛線(====)表示無法直接在圖上看到的第二直管部5的外部配置。 Please note that in the reference perspective view 1 and the reference perspective view 2, the dashed line (-----) represents the relatively visible external configuration of the second straight pipe portion 5 moved to a position different from the initial position (indicated by the solid line). The double dashed line (====) indicates the external configuration of the second straight pipe portion 5 that cannot be directly seen on the figure.

另一方面，參考立體圖2示出了第二情況下的配置，其中如圓形允許線B所示第二直管部5以360°的角度，沿著耦接環10的邊緣圓周在與上述基本平面S垂直的單獨的表面T上樞轉，並且保持第一直管部1被固定。 On the other hand, referring to the perspective view 2 shows the configuration in the second case, in which the second straight pipe portion 5 is at an angle of 360° as shown by the circular allowable line B, along the edge circumference of the coupling ring 10, and It pivots on a separate surface T perpendicular to the basic plane S, and keeps the first straight pipe portion 1 fixed.

因此，參考立體圖2以虛線示出了在這第二情況下第二直管部5的自由端部分20的位置可以變化多大和多廣。 Therefore, referring to the perspective view 2, it is shown in dotted lines how much and how widely the position of the free end portion 20 of the second straight pipe portion 5 can vary in this second situation.
