The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] like Figures 1 to 4As shown, the present invention provides a gas telescopic quick connector device 100, including a first connector part 1 and a second connector part 2, the first connector part 1 includes a connecting pipe structure, one end of the connecting pipe structure is used to connect with a fixed platform pipeline (existing technology, a part to be connected), and the other end of the connecting pipe structure is connected to a male plug 11, and a plug-in drive mechanism (a pneumatic, electric or hydraulic drive mechanism, which can be used with existing technology) is connected to the connecting pipe structure, and the male plug 11 can slide and swing under the drive of the connecting pipe structure; the second connector part 2 includes a female socket 21 that can be plugged in or separated from the male plug 11, and the female socket 21 is used to connect with a mobile vehicle body pipeline (existing technology, a part to be connected).

[0036] The gas telescopic quick connector device of the present invention directly drives and controls the engagement or separation of the male plug and the female socket through a plug-in drive mechanism, and has a high degree of automation; the connecting pipe structure connected to the fixed platform pipeline is telescopic and swingable, and can eliminate certain angles and radial deviations to achieve automatic docking; the gas telescopic quick connector device of the present invention can have an open design for the diameter size, and has few restrictions on the diameter size, which can meet the demand for a large diameter, has good connection air tightness, and is highly safe; the gas telescopic quick connector device of the present invention has a simple structure, is easy to manufacture and install, is reliable to use, and is easy to maintain.

[0037] Further, if Figure 1 As shown, the connecting pipe structure includes a fixed pipe 12 for fixedly connecting to a fixed platform (prior art), the first end of the fixed pipe 12 is connected to the fixed platform pipeline (prior art, the part to be connected), the second end of the fixed pipe 12 is connected to a sliding pipe 13, the first end of the sliding pipe 13 is slidably inserted into the fixed pipe 12, the second end of the sliding pipe 13 is connected to a swinging pipe 14, the first end of the swinging pipe 14 is swingably connected to the sliding pipe 13, and the second end of the swinging pipe 14 is connected to a convex plug 11.

[0038] The sliding pipe 13 can slide along the fixed pipe 12 to meet the needs of expansion and contraction during the plugging and unplugging process of the gas telescopic quick connector device; the swinging pipe 14 can swing relative to the sliding pipe 13 to eliminate certain angles and radial deviations to meet the needs of automated docking.

[0039] Further, if Figure 1 As shown, a sliding frame 15 is sleeved on the outer side of the swing pipe 14 , and the sliding frame 15 can drive the swing pipe 14 and the sliding pipe 13 to slide along the axial direction of the fixed pipe, and the swing pipe 14 can swing in the sliding frame 15 .

[0040] like Figure 1As shown, in this embodiment, a swing pipe channel is provided in the sliding frame 15 along the axial direction of the fixed pipe, a rubber sleeve 16 is provided in the swing pipe channel, and the swing pipe 14 passes through the rubber sleeve 16, and the swing pipe 14 can swing along the radial direction of the fixed pipe in the rubber sleeve 16. The rubber sleeve 16 is elastic, so that the sliding frame 15 can drive the swing pipe 14 to slide while allowing the swing pipe 14 to swing inside the sliding frame 15 (the swing of the swing pipe is a small angle swing to eliminate a certain angle and radial deviation).

[0041] Furthermore, the aforementioned plug-in drive mechanism is connected to the sliding frame 15. The plug-in drive mechanism is fixedly connected to the sliding frame to avoid directly clamping the pipeline and ensure the stability and safety of the drive.

[0042] Furthermore, the first end of the swing pipe 14 is connected to the second end of the sliding pipe 13 through a rubber joint 17, and the rubber joint 17 can be extended and retracted along the axial direction of the fixed pipe and can swing along the radial direction of the fixed pipe. The rubber joint 17 can prevent the swing pipe 14 from being affected by the sliding pipe 13 when the swing pipe 14 swings at an angle.

[0043] Further, if Figure 1 , Figure 2 As shown, the male plug 11 includes a plug housing 111, a first guide frame 112 is sleeved on one side of the plug housing 111 close to the swing pipe 14, a first valve flap 113 is slidably penetrated at the center of the first guide frame 112, a first through groove 114 is arranged on the first guide frame 112 on the radially outer side of the first valve flap 113, a first conical stop surface 115 with a diameter gradually expanding from the outside to the inside is arranged on the end of the plug housing 111 away from the swing pipe 14, a first stop ring 116 that can be abutted and stopped on the first conical stop surface 115 is arranged on the first valve flap 113, and a first abutting column 117 is arranged on the end of the first valve flap 113 away from the swing pipe 14; a first spring 118 is sleeved on the first valve flap 113, and the two ends of the first spring 118 abut against the first guide frame 112 and the first stop ring 116 respectively. Figure 1 As shown, when the male plug 11 and the female socket 21 are in a separated state, the first retaining ring 116 is pressed against and sealed on the first conical retaining surface 115 under the action of the first spring 118, and the male plug 11 is in a closed state; Figure 4 As shown, when the male plug 11 is plugged into the female socket 21, the first retaining ring 116 moves axially away from the first conical retaining surface 115 under the action of the axial force, and the male plug 11 is in a connected state.

[0044] Further, if Figure 1 , Figure 3As shown, the female socket 21 includes a socket housing 211, and the plug housing 111 can be sealed and inserted into the socket housing 211; a second guide frame 212 is sleeved on the side of the socket housing 211 away from the first joint part 1, and a second valve flap 213 is slidably penetrated at the center of the second guide frame 212, and a second through groove 214 is arranged on the radial outer side of the second valve flap 213 on the second guide frame 212, and a second conical stop surface 215 is arranged in the socket housing 211, and the diameter of the second conical stop surface 215 is from the diameter away from the first joint part 1 to the diameter of the second conical stop surface 215. One side of the first joint portion is gradually expanded toward the side close to the first joint portion (the second conical stop surface 215 is symmetrically arranged with the first conical stop surface 115), a second stop ring 216 is arranged on the second valve flap 213, which can be abutted against and stopped on the second conical stop surface 215, and a second abutting column 217 is arranged at one end of the second valve flap 213 close to the first joint portion; a second spring 218 is sleeved on the second valve flap 213, and the two ends of the second spring 218 are respectively pressed against the second guide frame 212 and the second stop ring 216. Figure 1 As shown, when the male plug 11 and the female socket 21 are in a separated state, the second retaining ring 216 is pressed and sealed against the second conical retaining surface 215 under the action of the second spring 218, and the female socket 21 is in a closed state; Figure 4 As shown, when the male plug 11 is plugged into the female socket 21, the second retaining ring 216 moves axially away from the second conical retaining surface 215 under the action of the axial force, and the female socket 21 is in a connected state.

[0045] Further, if Figure 1 As shown, the socket housing 211 can be fixedly connected to the fixing frame 22, and the fixing frame 22 is used to be connected to the mobile vehicle body.

[0046] Further, if Figure 1 As shown, to ensure the sealing effect, a first sealing ring 31 is arranged between the sliding pipe 13 and the fixed pipe 12; a second sealing ring 32 is sleeved on the first retaining ring 116; a third sealing ring 33 is sleeved on the second retaining ring 216; and a fourth sealing ring 34 is sleeved on the outer wall of the plug housing 111.

[0047] The working process of the gas telescopic quick connector device 100 of the present invention is as follows:

[0048] The joint connection process is as follows: the plug-in drive mechanism pushes the sliding frame 15 to slide in the direction close to the second joint part 2, and the male plug 11 is inserted into the socket housing 211 of the female socket 21 under the action of the sliding frame 15, and the first top support column 117 of the first valve flap 113 is pressed against the second top support column 217 of the second valve flap 213, and the first spring 118 and the second spring 218 are both compressed, and the first retaining ring 116 leaves the first conical retaining surface 115, and the second retaining ring 216 leaves the second conical retaining surface 215, and the male plug 11 and the female socket 21 are in a connected state, and the fixed platform pipeline connected to the first joint part 1 and the mobile vehicle body pipeline connected to the second joint part 2 are connected; at this time, the plug housing 111 is inserted into the socket housing 211, and is sealed by the fourth sealing ring 34, so that the gas in the pipeline will not overflow.

[0049] The disconnection process of the joint is opposite to the connection process. The plug-in drive mechanism pushes the sliding frame 15 to slide in the direction away from the second joint part 2, and the first abutting column 117 and the second abutting column 217 no longer abut each other. The first spring 118 and the second spring 218 rebound. Under their action, the first retaining ring 116 abuts against the first conical retaining surface 115, and the second retaining ring 216 abuts against the second conical retaining surface 215. The male plug 11 and the female socket 21 are both in a closed state. After closing, the male plug 11 is disengaged from the female socket 21, and the gas in the pipeline will not overflow.

[0050] As described above, the gas expansion quick connector device provided by the present invention has the following beneficial effects:

[0051] The gas telescopic quick connector device of the present invention directly drives and controls the engagement or separation of the male plug and the female socket through a plug-in drive mechanism, and has a high degree of automation; the connecting pipe structure connected to the fixed platform pipeline is telescopic and swingable, and can eliminate certain angles and radial deviations to achieve automatic docking; the sliding pipe can slide along the fixed pipe to meet the telescopic requirements of the gas telescopic quick connector device during the plug-in and pull-out process; the swinging pipe can swing relative to the sliding pipe, and can eliminate certain angles and radial deviations to meet the requirements of automatic docking; the gas telescopic quick connector device of the present invention can have an open design for the diameter size, and has fewer restrictions on the diameter size, which can meet the requirements of a large diameter, good connection air tightness, and high safety; the gas telescopic quick connector device of the present invention has a simple structure, is easy to manufacture and install, is reliable to use, and is easy to maintain.
