Description

Technical Field

[0001] This invention relates to a fluid connector, and more particularly to a fluid connector with a ball valve structure. Background Technology

[0002] Fluid connectors are used in piping systems for fluid transport, primarily for quickly connecting or disconnecting two pipe sections while controlling the flow of fluid. Traditionally, fluid connector designs have focused on sealing performance and ease of operation, but in practical applications, the following technical defects and limitations still exist.

[0031] To provide a more detailed and complete description of this invention, reference can be made to the accompanying drawings and the various embodiments described below, in which the same numbers represent the same or similar elements. Furthermore, well-known elements and steps are not described in the embodiments to avoid unnecessarily limiting the scope of this invention.

[0032] In the embodiments and claims, unless otherwise specified in the text, “a” and “the” may refer to one or more.

[0033] Please refer to Figures 1 and 2 simultaneously. Figure 1 A perspective view of the fluid connector 100 of this novel invention in the on-state is shown. Figure 2 Show Figure 1The figure shows a perspective view of the fluid connector 100 with the interlocking mechanism exposed after removing part of the main body. The main body 102 of the fluid connector 100 has a first end 102a and a second end 102b, and a fluid channel 106 extends from the first end 102a to the second end 102b. The first end 102a of the main body 102 is provided with a docking platform 104. When the fluid connector 100 is in the open state, the fluid channel 106 allows fluid to flow freely.

[0034] The fluid connector 100 has a switch 120 disposed on the body 102, and includes a handle 120a and a positioning component 120b. The switch 120 controls the fluid connector 100 to switch between an open state and a locked state. When the fluid connector 100 is in the open state, the handle 120a has an open position relative to the body 102 (i.e., the length direction of the handle 120a is approximately parallel to the length direction of the body 102). The positioning component 120b is used for positioning and unlocking the handle 120a.

[0035] The valve assembly 150 of the fluid connector 100 includes a ball core 152, a shaft connector 154, and a shaft connector 156. The ball core 152 is located between the shaft connectors 154 and 156, and is rotatably pivotally connected to the body 102 via the shaft connectors 154 and 156. The shaft connector 154 connects the ball core 152 to the handle 120a, allowing the ball core 152 to rotate synchronously with the handle 120a. Under the thrust of the spring 156a, the shaft connector 156 securely pivots the ball core 152 within the body 102.

[0036] The interlocking mechanism 140 of the fluid connector 100 includes a ball 142 (see [link]). Figure 5 The device comprises a fastener 144, a first rod 146, and a second rod 148. A ball bearing 142 is rotatably connected between the fastener 144 and the cam 123 of the switch 120. The fastener 144 passes through the groove 146a of the first rod 146 and abuts against the second rod 148. The interlocking mechanism 140 controls the interlocking operation of the two fluid connectors 100. The fastener 144, by the thrust of two springs 143, allows the ball bearing 142 to be securely rotatably connected between the fastener 144 and the cam 123 of the handle 120a, preventing displacement. The cam 123 of the handle 120a is connected to a shaft connector 154. When the handle 120a is rotated, it drives the cam 123, the shaft connector 154, and the ball bearing 152 to rotate. The docking platform 104 has a first rod groove 122, a second rod groove 124, and a positioning groove 126. The first rod 146 is housed in the first rod slot 122, and is pushed outward from the first rod slot 122 by the thrust of the spring 146d. The second rod 148 is housed in the second rod slot 124, and is pushed outward from the second rod slot 124 by the thrust of the spring 148d.

[0037] Please refer to Figures 3 and 4 at the same time. Figure 3 A perspective view of the fluid connector 100 of this novel invention in the locked state is shown. Figure 4 Show Figure 3 The figure shows a perspective view of the fluid connector 100 with the main body removed, exposing the interlocking mechanism. When the fluid connector 100 is in the locked state, the fluid passage 106 is blocked by the ball core 152, preventing free fluid flow. The switch 120 controls the fluid connector 100 to switch between the open and locked states. When the fluid connector 100 is in the locked state, the handle 120a has a locked position relative to the main body 102 (i.e., the length direction of the handle 120a is approximately perpendicular to the length direction of the main body 102).

[0038] Compared to the open state of the fluid connector 100, rotating the switch 120 so that the length direction of the handle 120a is approximately perpendicular to the length direction of the body 102 controls the valve assembly 150, and rotating the ball core 152 so that its through hole 152a is not connected to the fluid channel 106 of the body 102, thus preventing the fluid from flowing freely in the fluid channel 106, thereby achieving the closed state of the fluid connector 100.

[0039] When the fluid connector 100 is in the open state, the through hole 152a of the ball core 152 will rotate to the position aligned with the fluid channel 106 (i.e., the through hole 152a connects to the fluid channel 106), so as to achieve the purpose of free flow of fluid in the fluid channel 106.

[0040] Please refer to Figure 5 This diagram shows a top view of the interlocking mechanism and valve assembly of the novel fluid connector in the open state. To clearly show the interlocking mechanism 140, the handle 120a has been removed, exposing the handle cam 123 and the interlocking mechanism 140. The interlocking mechanism 140 includes a ball bearing 142, a fastener 144, a first lever 146, and a second lever 148, and interacts with the handle cam 123 to achieve interlocking and malfunction protection of the fluid connector.

[0041] The ball bearing 142 is connected between the groove 145 of the fastener 144 and the cam 123 of the handle. The inner surface of the groove 145 fits the spherical ball bearing 142, so that the ball bearing 142 can smoothly roll between the fastener 144 and the cam 123.

[0042] Fastener 144 includes a flat plate 144a and a columnar member 144b, the columnar member 144b extending from the flat plate 144a, and a groove 145 disposed on the side of the flat plate 144a opposite to the columnar member 144b. Cam 123 has a larger radius r1 and a smaller radius r2, the radius being the distance from the pivot center 121 of cam 123 to its outer edge. Second rod 148 has a first outer diameter D1, a second outer diameter D2, and a third outer diameter D3, the first outer diameter D1 being smaller than the second outer diameter D2, and the second outer diameter D2 being smaller than the third outer diameter D3. First region 148a of second rod 148 has the first outer diameter D1, second region 148b of second rod 148 has the second outer diameter D2, third region 148c of second rod 148 has the third outer diameter D3, and fourth region 148e of second rod 148 has the third outer diameter D3. The first region 148a connects the second region 148b and the third region 148c, forming a recessed area. The second region 148b connects the first region 148a and the fourth region 148e, and the second region 148b is a recessed area relative to the fourth region 148e. The first rod 146 has a shallow limiting groove 146b, a deeper limiting groove 146c, and a sliding groove 146a. The limiting grooves 146b and 146c are connected to each other to form a stepped structure. The sliding groove 146a penetrates part of the bottom of the deeper limiting groove 146c.

[0043] When the fluid connector 100 is in the open state, the outer edge of the cam 123, with its larger radius r1, abuts against the ball 142, pushing the flat plate 144a of the fastener 144 to engage with the deeper limiting groove 146c of the first rod 146. The first rod 146 is thus restricted from sliding. The columnar member 144b of the fastener 144 also passes through the groove 146a and slides against the first region 148a of the minimum first outer diameter D1 of the second rod, thus restricting the second rod 148 from sliding. Therefore, both the first rod 146 and the second rod 148 are mutually restricted from sliding.

[0044] Please refer to Figure 6The figure shows a top view of the interlocking mechanism and valve assembly of the fluid connector in the locked state. When the fluid connector 100 is in the locked state, because the outer edge of the smaller radius r2 of the cam 123 abuts against the ball 142, the fastener 144, under the upward thrust of its spring 143 (see also Figures 9 and 10), causes the flat plate 144a of the fastener 144 to disengage from the deeper limiting groove 146c of the first rod 146 and slide within the shallower limiting groove 146b of the first rod 146. The columnar member 144b of the fastener 144 also disengages from the first region 148a of the first outer diameter D1 of the second rod and slides against the second region 148b of the second outer diameter D2 (second smallest outer diameter) of the second rod 148. Therefore, cam 123 is restricted from rotating by fastener 144, while first rod 146 and second rod 148 are unrestricted and can slide or rotate towards springs 146d and 148d. When second rod 148 slides towards spring 148d, causing the first region 148a of the first outer diameter D1 to be directly below (or vertically overlapping) the columnar member 144b of fastener 144, the columnar member 144b of fastener 144 has not yet abutted the first region 148a. Thus, the restriction of cam 123 by fastener 144 can be released. At this time, after positioning component 120b unlocks and opens handle 120a, handle 120a can rotate cam 123 to the outer edge of larger radius r1 abutting ball 142, thereby pushing columnar member 144b abutting the first region 148a, and thus restoring fluid connector 100 to its original position. Figure 5 The status shown is active.

[0045] Please refer to Figure 7 The diagram shows a perspective view of the novel fluid connector interlocking system 200. The fluid connector interlocking system 200 includes two fluid connectors 100. For the interlocking relationship of the docking platforms of the two fluid connectors 100, the body portion of one of the fluid connectors 100 is removed to expose the interlocking mechanism 140. When the docking platforms 104 of the two fluid connectors 100 are interlocked, the two docking platforms 104 are rotatably interlocked using their respective locking tongues 105 and locking tongue grooves 107, and the first rod 146 of one fluid connector 100 protrudes from the first rod groove 122 and inserts into the positioning groove 126 of the other fluid connector 100 (see also [reference]). Figure 1The second rod 148 is then pressed by the other fluid connector 100 and moves towards the spring 148d, so that the first region 148a with the smallest outer diameter D1 is located directly below the columnar member 144b of the fastener 144. This releases the fastener 144 from restricting the cam 123, allowing the cam 123 to rotate to the outer edge of the larger radius r1 to abut against the ball 142, thereby enabling the fluid connector 100 to switch from the locked state to the open state. In this embodiment, when the two fluid connectors 100 are docked, the second rod 148 is pressed by the locking tongue 105 of the other fluid connector 100 and moves towards the spring 148d. However, this invention is not limited to this, and the second rod 148 can also be configured to be pressed by the second rod 148 of the other fluid connector 100 and move towards the spring 148d.

[0046] If both fluid connectors 100 are in the open state, the first rod 146 and the second rod 148 are both restricted from sliding or rotating (see above). Figure 5 (Description of the open state of fluid connector 100), and the first rod 146 is inserted into the positioning groove 126 of the other fluid connector 100, so that the docking platform 104 of the two fluid connectors 100 cannot be rotated to unlock, thus avoiding liquid leakage when unlocking.

[0047] Please refer to Figure 8 and Figure 11 , Figure 8 A cross-sectional view of the positioning assembly 120b of the switching element of the fluid connector of this novel invention is shown. Figure 11 The diagram shows a top view of the slide rail 129b and groove 129a on the body of the fluid connector of this invention. A positioning assembly 120b is used to lock or unlock the switch, allowing the handle 120a to be positioned or slide freely. The positioning assembly 120b includes a button lever 127 and a ball bearing 129. The button lever 127 has a receiving groove 127d and a limiting groove 127c, which are continuous grooves on the button lever 127, with the receiving groove 127d being deeper than the limiting groove 127c. The button lever 127 is disposed within the handle 120a, and the ball bearing 129 is positioned between the limiting groove 127c of the button lever 127 and the groove 129a of the slide rail 129b by the thrust of the spring 127a, preventing the handle 120a from rotating. The groove 129a is a recess on the slide rail 129b used to position the ball bearing 129. When the button lever 127 is pressed in the direction of the arrow in the figure, aligning the button lever 127 receiving groove 127d with the ball bearing 129, the ball bearing 129 is allowed to roll, the handle 120a can rotate, and the ball bearing 129 can roll on the slide rail 129b. The handle 120a can rotate relative to the body 102 to the open position (see reference). Figure 1 ) or locked position (refer to) Figure 3 ).

[0048] Please refer to Figure 9 This diagram shows a cross-sectional view around the fastener 144 of the fluid connector 100 of the present invention. This cross-section reveals the fastener 144, the spring 143, and its spring groove 147. Two spring grooves 147 are located within the body 102 for accommodating two springs 143, respectively. The two springs 143 are connected to the flat plate 144a of the fastener 144, providing a thrust to press the flat plate 144a against the ball 142, thereby preventing displacement of the ball 142.

[0049] The novel fluid connector and its interlocking system achieve a docking interlock and malfunction protection mechanism for the fluid connector through the interconnection of the aforementioned valve assembly, switching element and interlocking mechanism.

[0050] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention.
