Description

Technical Field

[0001] This utility model relates to the technical field of automotive connectors, specifically a bidirectional interlocking anti-disconnection quick-connect connector. Background Technology

[0002] In the automotive industry, with the development of automobiles, there are more and more pipes on cars, the assembly space is decreasing, and the pipe structure is becoming more complex. The stability of pipe connections is related to vehicle performance and safety. Traditional automotive quick-connect fittings use ordinary snap-fit ​​assembly connections or a structure with conical seals and threaded locking for connection. The former is limited by space, the minimum installation size of the connector is large, which is not conducive to the assembly of connectors in narrow spaces and is inconvenient to operate. The latter is easily damaged during the disassembly process during maintenance and other operations.

[0003] To address the aforementioned deficiencies, the prior art (Chinese patent with publication number CN208295369U and publication date of 2018-12-28) includes a quick-connect connector and an automobile, comprising a quick-connect female connector and a quick-connect male connector. The quick-connect female connector has a first cavity penetrating through its first and second ends. The second end of the quick-connect female connector is fixedly connected to a first component to be connected. The first end of the quick-connect male connector is fitted with a sealing ring. The second end of the quick-connect male connector is fixedly connected to a second component to be connected. The first end of the quick-connect male connector is inserted into the first cavity of the quick-connect female connector through the first end of the quick-connect female connector and engages with the inner wall of the quick-connect female connector through the sealing ring.

[0004] The above solution uses a plug-in connection method for fixation, which is reinforced with fasteners. However, both the plug-in and reinforcement methods are unidirectional. During the driving process, cars will experience various road conditions, resulting in vibration and impact. The simple plug-in connection method is more prone to connection failure under long-term vibration and impact. Utility Model Content

[0005] The purpose of this utility model is to provide a bidirectional interlocking anti-disconnection quick connector to solve the problem of existing quick connectors mentioned in the background art, which have a single connection direction and method. During use, when a car experiences various road conditions, vibrations and impacts are generated. The simple plug-in fixing method is more prone to connection failure under long-term vibration and impact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional interlocking anti-disconnection quick connector, comprising a first connector, wherein a second connector is inserted into the top of the first connector;

[0007] A pressing member is symmetrically and slidably connected to the outer side of the first connector. The pressing member is connected to the anti-disengagement groove, and the anti-disengagement groove is correspondingly opened on the inner wall of the second connector.

[0008] The second connector has a transverse groove at equal angles on its side, and an outer fixing frame is slidably connected in the transverse groove. The bottom of the outer fixing frame is engaged with a locking groove, which is opened at equal angles on the outside of the first connector.

[0009] The inner wall of the second connector is provided with a first sealing ring and a second sealing ring from bottom to top, and the first sealing ring and the second sealing ring are located on the mating surface where the first connector and the second connector are inserted.

[0010] Furthermore, the pressing component is configured with an "L" shaped structure, the top of the pressing component is configured with a barb-shaped structure, a first spring is connected between the pressing component and the first connector, and the top of the pressing component abuts against the inside of the anti-detachment groove in an alternating manner.

[0011] Furthermore, a horizontal plate is slidably connected through the side of the anti-detachment groove, and the horizontal plate is slidably connected through the interior of the second connector. A second spring is installed between the horizontal plate and the inner wall.

[0012] Furthermore, the end of the horizontal plate is configured as a hemispherical structure, the end of the horizontal plate abuts against the insertion rod, the insertion rod is slidably connected to the inner wall of the second connector through a third spring, the outside of the insertion rod is inserted into the slot, and the slot is symmetrically opened on the top outer side of the first connector.

[0013] Furthermore, a vertical rod is slidably connected through the insertion point of the second connector and the first connector. The vertical rod is connected through the horizontal groove, and the top of the vertical rod is slidably connected in the guide groove. The guide groove is opened on the front side of the outer frame. The outer frame forms a horizontal sliding structure through the vertical rod and the guide groove. The outer frame is set as a "C" shaped structure.

[0014] Furthermore, a notch is provided on the inner wall of the anti-detachment groove, and a movable block is connected inside the notch by a fourth spring. A first airbag is provided between the movable block and the notch. The first airbag is connected to a first sealing ring through a connecting pipe. The first sealing ring is located on the outer ring of the mating surface of the first connector and the second connector.

[0015] Furthermore, a second airbag is installed inside the transverse groove, and the outer fixing frame is in compression contact with the second airbag. The second airbag is connected to the second sealing ring through a connecting pipe, and the second sealing ring is located on the inner ring of the mating surface of the first connector and the second connector.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This two-way interlocking anti-disengagement quick connector, due to its robust structure and excellent locking performance, can better adapt to these complex working conditions during use, reducing loosening or damage to the connector caused by vibration and impact, making the connection more stable, and preventing pipeline leaks from affecting the normal operation of the vehicle.

[0018] 1. Further, after pressing the two pressing parts, the pressing parts compress the first spring, making it easier to insert into the anti-disengagement groove. After insertion, the pressing parts are released, and the first spring drives it to return to its original position. The barb structure at the top of the pressing parts will interlock and abut against the inner wall of the anti-disengagement groove, thereby connecting and fixing it. When the pressing parts extend into the anti-disengagement groove, they will press the horizontal plate. The horizontal plate compresses the second spring and moves. After the horizontal plate moves, it abuts against the inclined surface of the insertion rod, thereby pushing the insertion rod to move outward and compress the third spring to engage with the slot on the outside of the first connector, thereby connecting and fixing the first connector and the second connector in the horizontal and vertical directions.

[0019] 2. Furthermore, after the first connector and the second connector are inserted, they will compress the vertical rod, thereby pushing the vertical rod to slide. After the vertical rod slides, it will push the outer fixing frame to retract and slide inward along the guide groove. After the outer fixing frame slides, it will be inserted into the locking groove on the outside of the first connector, thereby realizing bidirectional locking between the first connector and the second connector.

[0020] 3. Furthermore, when the pressing part is inserted into the anti-dislodgement groove, it will squeeze the movable block in the recess. The movable block compresses the fourth spring and squeezes the first airbag. After the first airbag is compressed, it delivers gas to the first sealing ring. The first sealing ring will then seal the outer ring of the mating surface of the first connector and the second connector.

[0021] 4. Furthermore, when the outer retainer retracts and slides, it will compress the second airbag in the transverse groove. The gas in the second airbag is delivered to the second sealing ring, which will seal the inner ring of the mating surface of the first and second joints, thereby achieving a double sealing effect and improving the sealing performance after the automotive pipeline is connected.
