Description

Technical Field

[0001] This invention relates to a fluid connector assembly, and more particularly to a fluid connector assembly with a release fixture. Background Technology

[0002] Quick-connect fluid couplings are connection elements specifically designed for hydraulic, pneumatic, or other fluid systems, enabling rapid connection and disconnection of pipelines without the use of tools. The basic structure of a quick-connect fluid coupling typically includes a male and a female connector, with a specially designed mechanism ensuring a seal and secure fit. This design significantly reduces installation and maintenance time and lowers the risk of fluid leakage caused by disassembly and assembly.

[0003] However, connecting and disconnecting certain quick couplings without tools still requires special skill and strength from the user. More innovative improvements are needed to enhance the efficiency of quick coupling connection and disconnection. Utility Model Content

[0004] This invention proposes a fluid connector assembly that solves the problems of prior art.

[0005] According to one embodiment of the present invention, a fluid connector assembly includes a female connector body, a male connector body, a valve ring sleeve, and a release fixture. The female connector body has a connecting channel, two positioning grooves, two positioning rods, and a gasket ring. The two positioning grooves communicate between the outer wall of the female connector body and the inner wall of the connecting channel. The two positioning rods are slidably connected within the two positioning grooves, and the gasket ring is fitted onto the outer wall of the female connector body and located below the two positioning rods. The male connector body has a connecting portion housed within the connecting channel. The connecting portion has a male groove, and the two positioning rods are located within the male groove when exposed on the inner wall of the connecting channel. The valve ring sleeve is fitted onto the female connector body and abuts against the two positioning rods. The release fixture is fitted onto the valve ring sleeve and abuts against the upper edge of the valve ring sleeve.

[0006] According to another embodiment of the present invention, the male head body has an L-shaped fluid channel or a straight fluid channel.

[0007] According to another embodiment of the present invention, the release fixture has a baffle that abuts against the upper edge of the valve ring.

[0008] According to another embodiment of the present invention, the angle between the extending directions of the two positioning grooves and the axial direction of the female head body is an acute angle.

[0009] According to another embodiment of the present invention, the female head body further includes an annular protrusion and a spring, the spring being surrounded by the outer wall of the female head body and located between the gasket ring and the annular protrusion.

[0010] According to another embodiment of the present invention, the female head body further includes a threaded connection portion, and the annular protrusion is located between the spring and the threaded connection portion.

[0011] According to another embodiment of the present invention, the release fixture has a semicircular ring and a baffle plate, the baffle plate abutting against the upper edge of the valve ring sleeve, and the semicircular ring abutting against the side wall of the valve ring sleeve.

[0012] According to another embodiment of the present invention, the baffle includes a semi-circular groove or a two-thirds circular groove.

[0013] According to another embodiment of the present invention, the valve ring sleeve has a flange ring that abuts against the two positioning rods.

[0014] According to another embodiment of the present invention, when the release fixture is pressed down, the baffle presses down against the upper edge of the valve ring sleeve, the flange ring of the valve ring sleeve presses down on the two positioning rods and drives the gasket ring to move down, so that the two positioning rods disengage from the male head groove.

[0015] In summary, this novel fluid connector assembly, through the interconnection of its release fixture, valve ring sleeve, positioning groove, positioning rod, and gasket ring, achieves the ability to quickly unlock the male and female connector bodies from an interlocked state by applying force with a single hand to the release fixture.

[0056] AG: Angle Detailed Implementation

[0057] 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.

[0058] In the embodiments and claims, unless otherwise specified in the text, “a” and “the” may refer to one or more.

[0059] Please refer to the following at the same time Figure 1 , Figure 2 , Figure 1 A side view of the fluid connector assembly 100a according to a first embodiment of the present invention is shown. Figure 2 Draw Figure 1 A perspective view of the release fixture 130 of the fluid connector assembly 100a. The release fixture 130 is fitted onto the valve ring sleeve 140 and abuts against the upper edge of the valve ring sleeve 140 of the fluid connector assembly 100a, thereby more effectively controlling the fluid connector assembly 100a to quickly unlock from the interlocked state.

[0060] The fluid connector assembly 100a includes a female connector body 110, a male connector body 120, and a valve ring sleeve 140. The valve ring sleeve 140 is fitted onto the female connector body 110 to control the rapid unlocking of the fluid connector assembly 100a from the interlocked state. A release fixture 130 is fitted onto the valve ring sleeve 140, allowing the user to quickly unlock the female connector body 110 and the male connector body 120 of the fluid connector assembly 100a from the interlocked state by applying force with one hand.

[0061] The release fixture 130 includes a housing 131, a semicircular ring 132, and a baffle 133. The baffle 133 extends inward from the bottom end of the housing 131 to form a groove 133a. The semicircular ring 132 extends downward from the bottom end of the housing 131. The baffle 133 abuts against the upper edge of the valve ring sleeve 140, and the semicircular ring 132 abuts against the side wall of the valve ring sleeve 140.

[0062] Please refer to Figure 3 Its illustration Figure 1 The fluid connector assembly 100a is shown in a side view with the release fixture 130 and valve ring sleeve 140 removed. The female connector body 110 includes a threaded connection portion 110a, a coupling portion 110b, and an annular protrusion 110c. The annular protrusion 110c is located between the threaded connection portion 110a and the coupling portion 110b. The coupling portion 110b has two positioning grooves 114 and two positioning rods 113, with the two positioning rods 113 slidably connected within the two positioning grooves 114 respectively. Please also refer to... Figure 15The valve ring sleeve 140 has a flange ring 141 extending toward the coupling portion 110b on its inner side. The flange ring 141 is located above and abuts against the two positioning rods 113. A spring 111 surrounds the outer wall of the coupling portion 110b of the female head body and is located between the gasket ring 112 and the annular protrusion 110c. The spring 111 and the gasket ring 112 are both located between the valve ring sleeve 140 and the coupling portion 110b. The thrust provided by the spring 111 causes the gasket ring 112 to push the two positioning rods 113 upward and confine them within the two positioning grooves 114.

[0063] Please refer to the following at the same time Figures 4-6 , Figure 4 Draw Figure 1 A cross-sectional view of the fluid connector assembly 100a in its interlocked state along section AA. Figure 5 Draw Figure 1 A cross-sectional view of the fluid connector assembly in interlocking state two along section AA. Figure 6 Draw Figure 1 The fluid connector assembly is shown in a cross-sectional view along section AA in its unlocked state. The interlocked state of the fluid connector assembly 100a means that the connection portion 120b of the male connector body 120 and the coupling portion 110b of the female connector body 110 are interlocked.

[0064] The male connector body 120 includes a threaded connection portion 120a, a connecting portion 120b, and a turning portion 120c, with the turning portion 120c located between the threaded connection portion 120a and the connecting portion 120b. The connecting portion 120b of the male connector body 120 is inserted into and accommodated within the connecting channel 115 of the female connector body 110.

[0065] The male connector body 120 has a male connector groove 121 in its connecting portion 120b. Two positioning grooves 114 connect the outer wall of the coupling portion 110b and the inner wall of the connecting channel 115. When the connecting portion 120b of the male connector body 120 and the coupling portion 110b of the female connector body 110 are in an interlocked state (refer to...), Figure 4 Two positioning rods 113 are exposed on the inner wall of the connecting channel 115 and located within the male head groove 121, thereby preventing relative movement between the connecting portion 120b of the male head body 120 and the coupling portion 110b of the female head body 110. (See reference...) Figure 5 The angle AG between the extension direction of the positioning groove 114 and the axial direction 110' of the female head body 110 is an acute angle. In other words, the extension direction of the positioning groove 114 allows the two positioning rods 113 to slide down by gravity (when the gasket ring 112 moves down and does not push the positioning rods 113).

[0066] Please refer to the following at the same time Figure 5 , Figure 15 When force is applied and the jig 130 is released (e.g.) Figure 4(In the direction of the arrow), when the connecting part 120b of the male head body 120 and the coupling part 110b of the female head body 110 are in the interlocked state (also known as the semi-unlocked state), the release fixture 130 abuts against the upper edge of the valve ring sleeve 140, causing the valve ring sleeve 140 to slide down. At this time, the baffle 133 of the release fixture 130 presses down the upper edge 140a of the valve ring sleeve 140, thereby causing the flange ring 141 of the valve ring sleeve 140 to abut against and press down the two positioning rods 113, and causing the gasket ring 112 to move down. This allows the two positioning rods 113 to slide down and disengage from the male head groove 121 by gravity and be located in the middle position of the positioning slide groove 114, so that the connecting part 120b of the male head body 120 and the coupling part 110b of the female head body 110 can slide relative to each other to unlock.

[0067] Next refer to Figure 6 , Figure 7 Under the elastic thrust of springs 161 and 163, the connecting part 120b of the male head body 120 is disengaged from the coupling part 110b of the female head body 110 and is in an unlocked state, so that the male head groove 121 of the connecting part 120b is disengaged from the coupling part 110b of the female head body 110 and is exposed.

[0068] The female connector body 110 also includes a valve body 160. The valve body 160 includes a bottom end 160a, a head 160b, and a stem 160c. The stem 160c has a smaller outer diameter and connects between the bottom end 160a and the head 160b. The bottom end 160a of the valve body 160 connects to the bottom opening 115a of the connection channel 115 of the female connector body 110. When the female connector body 110 and the male connector body 120 are in one or both interlocked states, the head 160b of the valve body 160 is slidably connected within the fluid channel 123 in the connection portion 120b of the male connector body 120.

[0069] Spring 161 is located in the fluid passage 123 of the male body 120 and is connected between the bend 120c and the valve head 162. Spring 163 is connected between the bottom end 160a of the valve body 160 and the valve sleeve 165 of the female body 110.

[0070] Reference Figure 4 , Figure 5 When the connecting portion 120b of the male connector body 120 and the coupling portion 110b of the female connector body 110 are in interlocked state one or two, the head 160b and the stem portion 160c of the valve body 160 are located in the fluid passage 123 of the male connector body 120, allowing fluid to flow freely through the fluid passage 123. Specifically, the outer diameter of the head 160b of the valve body 160 is smaller than the inner diameter of the flow-limiting section 123a of the fluid passage 123, thus allowing fluid to flow freely through the fluid passage 123.

[0071] Reference Figure 6 , Figure 7When the connecting portion 120b of the male connector body 120 and the coupling portion 110b of the female connector body 110 are in the unlocked state, neither the male connector body 120 nor the female connector body 110 allows free flow of fluid. Specifically, the outer diameter of the head 160b of the valve body 160 in the female connector body 110 seals the inner diameter of the valve sleeve 165, and the outer diameter of the valve sleeve 165 seals the inner diameter of the coupling portion 110b, preventing free flow of fluid in the connecting channel 115. At the same time, the outer diameter of the valve head 162 in the male connector body 120 seals the flow-limiting section 123a of the fluid channel 123, preventing free flow of fluid in the fluid channel 123.

[0072] Please refer to the following at the same time Figure 8 , Figure 9 , Figure 10 , Figure 8 A side view of the fluid connector assembly 100b according to the second embodiment of the present invention is shown. Figure 9 Draw Figure 8 A perspective view of the release fixture 130' of the fluid connector assembly. Figure 10 Draw Figure 8 The side view of the fluid connector assembly with the release fixture and valve ring removed. The main difference between fluid connector assembly 100b and fluid connector assembly 100a and the first embodiment lies in the structural differences of the male body 120' and the release fixture 130'.

[0073] The release fixture 130' includes a housing 131', a semicircular ring 132, and a baffle 133'. The baffle 133' extends inward from the bottom end of the housing 131' to form a groove 134. The semicircular ring 132 extends downward from the bottom end of the housing 131'. The baffle 133' abuts against the upper edge 140a of the valve ring sleeve 140, and the semicircular ring 132 abuts against the side wall of the valve ring sleeve 140.

[0074] The structural difference between release jig 130' and release jig 130 is that: cover 131' does not have a top wall 131a; groove 134 includes a two-thirds circular arc groove, while groove 133a includes a semi-circular arc groove. The design of cover 131' without a top wall is to match the shape of male head body 120' and also to give cover 131' the elasticity to recover from deformation, so that the groove 134 of baffle 133' can fit around male head body 120'. Although the structure of baffle 133' is slightly different from baffle 133, the actuation relationship between baffle 133' and valve ring sleeve 140, positioning rod 113 and gasket ring 112 is the same as in the first embodiment, and will not be described again.

[0075] Please refer to the following at the same time Figures 11-14 , Figure 11 Draw Figure 8 A cross-sectional view of the interlocking state of the fluid connector assembly 100b along section BB. Figure 12 Draw Figure 8 A cross-sectional view of the fluid connector assembly in interlocking state two along section BB. Figure 13 Draw Figure 8 A cross-sectional view of the fluid connector assembly in the unlocked state along section BB. Figure 14 Draw Figure 8 The side view of the fluid connector assembly in the unlocked state, removing the release fixture and valve ring sleeve.

[0076] The male connector body 120' includes a threaded connection portion 120a, a connecting portion 120b, and an annular protrusion 120d, with the annular protrusion 120d located between the threaded connection portion 120a and the connecting portion 120b. The male connector body 120' has a straight fluid channel 123'. The connecting portion 120b of the male connector body 120' is inserted into and accommodated within the connecting channel 115 of the female connector body 110.

[0077] The structural difference between the male head body 120' and the male head body 120 is that the male head body 120' has a straight fluid channel 123', while the male head body 120 has an L-shaped fluid channel 123. The release jig 130' is also modified to differ from the release jig 130 due to the structural difference of the male head body 120'.

[0078] The operation of the male connector body 120' and female connector body 110 in the interlocked and unlocked states of the fluid connector assembly 100b is basically the same as that of the fluid connector assembly 100a described above, and will not be repeated here.

[0079] This novel fluid connector assembly, through the interconnection of its release fixture, valve ring sleeve, positioning slide, positioning rod, and gasket ring, enables the male and female connector bodies of the fluid connector assembly to be quickly unlocked from the interlocked state by applying force with a single hand to the release fixture.

[0080] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art may make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
