Abstract
A concentric slide clamshell coupler 10 includes a pair of primary arcuate shaped coupling halves 12 joined at a hinge. Concentrically arranged secondary arcuate shaped coupling halves 20 are nested within the primary coupling halves 12. The primary and secondary coupling halves have respective hinges. When the hinges are aligned, the coupler may be opened. To close and lock the coupler about abutting ends of two fluid conveying members, the secondary coupling halves 20 are rotated within channels of the primary coupling halves 12, thereby separating the respective hinge elements from one another, and moving a portion of one of the secondary coupling halves 20 to span across distal facing surfaces of the primary coupling halves 12. In relation to a longitudinal axis of the connected fluid conveying members, the coupler when closed and locked creates a continuous ring around the ends of the fluid conveying members. The continuous ring locking features and hinge create redundant load carrying mechanisms.

With reference to Fig. 5, the figure shows fluid delivery component 30 and how to be fixed in joiner.As shown in the figure, sleeve 37 is stuck between the subtend end of flange 34.The outer rim 38 of flange 34 and sleeve 37 is blocked by annular extension 19 and can contact with the inner peripheral surface of annular extension 19.As mentioned above, how the present invention is being connected about fluid delivery component and seal aspect is not confined to any particular configuration especially relative to each other, and therefore this figure is the example of a kind of possible configuration how fluid delivery component is connected by joiner.
With reference to Fig. 6, its to show in the sectional views about major and minor coupling halves between the alternate embodiment at interface.In the figure, the slidably relation between major and minor coupling halves connects realization by dovetail type.More specifically, main coupling halves 12 is shown having in a pair of dovetail joint shape laterally spaced inner tracks 51.These tracks 51 extend radially inwardly.Secondary coupling halves 20 is arranged on outstanding track 51, and secondary coupling halves 20 has the dovetail joint shape opening 52 of a pair correspondence.Also imagine this dovetail joint to connect and can arrange in the opposite manner, that is, main coupling halves 12 can be combined with the recess of dovetail joint shape, and secondary coupling halves 20 can be combined with track or the extension part of the dovetail joint shape be received within recess.The sectional shape of secondary coupling halves can be described as the rectangle with dovetail joint shape track substantially.
In sectional view with reference to Fig. 7, this figure interface between the major and minor coupling halves of display, another alternate embodiment is also shown.In the figure, the slidably relation between major and minor coupling halves is connected realization by simple flange with groove.Therefore, because secondary coupling halves is not completely enclosed within the constraint portions of main coupling halves, so this interface may be defined as open.As shown in the figure, external connecting half portion 12 comprises annular slot or groove 54, and it is received from the outstanding complementary annular flange 56 of secondary coupling halves 20 radially outward.For each embodiment in these alternate embodiments, the motion between major and minor coupling halves realizes in the same manner.Secondary coupling halves is only slided or skew in concentric fashion, then locked in place as further discussed below.The shape of cross section of secondary coupling halves is as shown in the figure substantially in t shape.
Fig. 8 and 9 show further the basic structure details of main coupling halves 12.Fig. 8 also show about being used for other details of component of locking framework of the rotational position locking major and minor coupling halves.More specifically, the lock bolt base 74, respective pins opening 78 and the tooth anchor 80 that more fully describe in figs. 12 and 13 below showing of Fig. 8.
Figure 10 and 11 shows the basic structure details of secondary coupling halves 20 further.Particularly, Figure 10 show about hinge component and be used for other details of locking framework of the rotational position locking major and minor coupling halves.Joint portion 36 is shown having the pin opening 39 for hinge.Figure 10 also illustrates the locking member 82 on the outer surface being arranged on coupling halves 20.Locking member 82 comprises multiple elastic locking tooth 84 and buckle face 86.
With reference to Figure 12, joiner 10 is illustrated as the locking framework 68 of the rotational position had for locking major and minor coupling halves.As shown in the figure, secondary coupling halves has been rotated into the plane of distally in opposite directions between end 15 or gap that make one of them coupling halves cross over main coupling halves, and it roughly illustrates at plane/gap 88 place in fig. 12.Due to sizable quality that the transverse cross-sectional area of secondary coupling halves provides in this position, because herein is provided lock-in feature structure very reliably.---can imagine that this skew causes coupling halves to offset the position got back to such as shown in Fig. 2---to prevent skew unexpected between major and minor coupling halves to be necessary to arrange locking framework.Locking framework 68 comprises the lock bolt 70 be rotatably installed on the lock bolt base 74 of subtend.One pin (not shown) is positioned to the opening alignd created between the pin opening 78 of the alignment being passed in lock bolt base 74 and the pin opening (not shown) in the hinge part 76 being formed in lock bolt 70.The free end of lock bolt 70 comprises distally claw 72.Secondary coupling halves is rotated into and locking teeth 84 is inserted between tooth anchor 80 as shown in the figure.The pair of locking tooth 84 of outside is during rotation by slightly to interior extruding, and then decontrol when fully rotating to block tooth anchor 80, tooth 84 is tightly held in the gap between tooth anchor 80 thus.In this position, lock bolt 70 can be rotating closed, as shown in figure 13.Lock bolt 70 is rotated into and distally claw 72 is engaged with the buckle face 86 of locking member 82, thus lock bolt is fixed on operating position and prevents any motion between major and minor coupling halves.In addition, a pair protuberance 75 aliging of this lock bolt gap had between tooth 84.When lock bolt closes, protuberance 75 frictionally inserts in this gap, and this prevents any of tooth to open or move further.It is evident that, the lock operation that postrotational secondary coupling halves and locking framework 68 two are different provides locking redundancy.
The present invention it is contemplated that the locking framework of other form.Such as, replace illustrated locking framework 68, also imagination can utilize lock pin to realize locking, and described lock pin slips into a pair base with the opening be formed in main coupling halves with the opening alignd that formed between base of can aliging for a pair with the opening be formed in secondary coupling halves.More specifically, can setting example as shown in figure 12 with a pair base 74 of pin opening 78, and be formed in base and the opening of a pair like configurations in secondary coupling halves.When these openings are aligned, can use lock pin that coupling halves is remained on appropriate location.The button latch of interference is formed between the surface that the another kind of mode locking major and minor coupling halves can be included in major and minor coupling halves.Such as, with the elastic leaf springs of the outstanding button be arranged in one of main coupling halves can be aligned be formed in faced by secondary coupling halves on opening engage, and button inserts in this opening and can realize lock function.
According to a further aspect in the invention, a kind of method for fluid delivery component being connected to each other by joiner is provided.According to the method, provide a pair main coupling halves and a pair secondary coupling halves.Main coupling halves is arch, and forms clamshell style configuration.Coupling halves can move between the opened and the closed positions.In operating position, the end in opposite directions of coupling halves covering fluid transfer member is to connect parts.In order to coupling halves is locked in fluid delivery component, secondary coupling halves is directed with one heart about main coupling halves, and can rotate around longitudinal axis X-X (Fig. 1 and 3), described longitudinal axis limits such direction: coupling halves extends through joiner around this direction.After secondary coupling halves rotates, the hinged end of main coupling halves is crossed over by a part for one of secondary coupling halves, and the far-end in opposite directions of main coupling halves is also crossed over by another part of secondary coupling halves, prevents joiner to be opened thus.In order to prevent movement between major and minor coupling halves or translation, be provided with locking framework to lock the position of secondary coupling halves relative to main coupling halves.
Although described illustrative embodiment in detail in literary composition, it should be understood that above-mentioned concept can be implemented in further, different ways and adopt, and claims should be interpreted as comprising such modification, unless limited by prior art.
