[0044] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.

[0045] like Figures 1 to 9 As shown, the present embodiment discloses a quick connector device, which includes a plug 1, a socket 2, a quick connector 3 and an elastic top piece 4. The outer peripheral surface of the socket 2 has at least one slot 21, and the quick connector 3 has a through hole 31. One end of the through hole 31 can be rotatably sleeved on the plug 1. The elastic top piece 4 is located in the through hole 31, and the elastic top piece 4 is pressed between the quick connector 3 and the outer peripheral surface of the plug 1. The elastic top piece 4 applies a force on the quick connector 3 to limit the rotational movement of the quick connector 3. The socket 2 is inserted into the other end of the through hole 31, and the socket 2 and the plug 1 are plugged into each other. The other end of the through hole 31 has at least one buckle portion 32, and the quick connector 3 can rotate on the outer peripheral surface of the socket 2 so that the buckle portion 32 is buckled and connected to the slot 21 or detached from the slot 21.

[0046] In this embodiment, the through hole 31 penetrates the quick connector 3 along the axial direction of the quick connector 3, and the right end of the quick connector 3 is sleeved on the plug 1 and can rotate on the plug 1. When the quick connector device is in use, the plug 1 and the socket 2 are plugged into each other, and at the same time, the left end of the through hole 31 is sleeved on the socket 2, and the buckle part 32 will be located at the notch of the card slot 21, and the quick connector 3 can rotate on the outer peripheral surface of the socket 2. By rotating the quick connector 3, the quick connector 3 can rotate relative to the plug 1 and the socket 2, and the buckle part 32 rotates and is buckled in the card slot 21, so that the quick connector 3 is connected to the socket 2, that is, the plug 1, the socket 2 and the quick connector 3 are connected together. When the quick connector device needs to be disassembled, by rotating the quick connector 3, the quick connector 3 can rotate relative to the plug 1 and the socket 2, and the buckle part 32 rotates and disengages from the card slot 21, so that the quick connector 3 and the socket 2 can be disconnected from each other, and by applying a force on the plug 1 or the socket 2 along the axial direction, the plug 1 and the socket 2 can be disassembled from each other. By rotating the quick connector 3 , the buckle portion 32 can be buckled into or out of the slot 21 , thereby achieving mutual connection or mutual disassembly, which is very convenient and quick to use.

[0047] When the quick connector device is in use, the two ends of the quick connector 3 are respectively connected to the plug 1 and the socket 2 through the through hole 31. At the same time, the plug 1 and the socket 2 are plugged into each other, so that the connection between the plug 1 and the socket 2 is stable and reliable, with high safety and stability.

[0048] During the use of the quick connector device, the elastic top piece 4 is pressed between the quick connector 3 and the outer peripheral surface of the plug 1, and the elastic top piece 4 will apply a force to the inner wall surface of the quick connector 3 and / or the outer peripheral surface of the plug 1, thereby limiting the rotational movement of the quick connector 3. The elastic top piece 4 prevents the quick connector 3 and the plug 1 from generating a rotational movement, so that the snap-on portion 32 of the quick connector device is snap-connected to the snap-on slot 21 during use and does not fall out of the snap-on slot 21, effectively preventing the electrical connection between the plug 1 and the socket 2 from loosening and causing electrical connection failure or burning, and greatly enhancing the reliability and service life of the quick connector device.

[0049] When the quick connector device is normally used, the rotation of the quick connector 3 is limited by the elastic top piece 4. Of course, in special cases, when the quick connector 3 needs to be rotated for disassembly, a larger force can be applied or a tool can be used on the quick connector 3 to overcome the force applied by the elastic top piece 4 on the quick connector 3 to achieve the rotation of the quick connector 3.

[0050] In this embodiment, the number of the card slots 21 and the buckle parts 32 are both multiple and one-to-one corresponding, and the multiple card slots 21 are arranged at intervals along the circumference of the socket 2. The multiple buckle parts 32 are correspondingly buckled and connected to the multiple card slots 21, so that the connection stability between the quick connector 3 and the socket 2 is higher.

[0051] In this embodiment, when the plug 1 and the socket 2 are plugged into each other, the plug 1 and the socket 2 cannot rotate, thereby ensuring the stability of the electrical connection. The socket 2 and the plug 1 are plugged into each other through a buckle structure to prevent the socket 2 and the plug 1 from rotating along their circumferential direction. Specifically, the right end of the socket 2 and / or the left end of the plug 1 are provided with a buckle groove and a buckle component to achieve plugging. Of course, other structures can also be provided to achieve mutual plugging.

[0052] The outer surfaces of the plug 1 and the socket 2 are marked, and the marks facilitate accurate alignment of the plug 1 and the socket 2 when they are plugged into each other, which is very convenient to use.

[0053] The outer surface of the plug 1 has an inwardly recessed mounting groove 11, the bottom of the elastic top piece 4 is embedded in the mounting groove 11, the top of the elastic top piece 4 has an outwardly protruding elastic top 41, and the inner wall surface of the quick connector 3 has a plurality of damping grooves 33. The quick connector 3 rotates on the plug 1 so that the elastic top 41 sequentially extends into the plurality of damping grooves 33. When the quick connector device is installed or disassembled, the quick connector 3 and the plug 1 need to rotate relative to each other, and the elastic top 41 sequentially extends into the plurality of damping grooves 33, so that the operator has an obvious feeling of the elastic top 41 extending into the damping groove 33 when using it, so that the quick connector 3 and the plug 1 generate relative rotational movement and the surface operation is normal. The damping groove 33 has a certain blocking effect on the elastic top 41, and the quick connector 3 will not be able to rotate unless a large force is applied, thereby ensuring the structural stability and higher safety and stability. The mounting groove 11 is used to accommodate the elastic top piece 4 to limit the displacement and dislocation of the elastic top piece 4 during use, and has higher stability. At the same time, the structure is simple and easy to process and manufacture.

[0054] The outer surface of the quick connector 3 may also have a mark, which can remind the operator of the rotation direction for installation or removal, and can also remind the operator whether the installation or removal is in place.

[0055] In this embodiment, the elastic top member 4 is a centrifugal top spring, which has a simple structure and is easy to manufacture.

[0056] The outer peripheral surface of the socket 2 has at least one guide groove 22, which extends from the end of the socket 2 facing the plug 1 along the axial direction of the socket 2 in the direction away from the plug 1 to one end of the card slot 21 and is connected to the card slot 21. The other end of the card slot 21 is extended along the circumferential direction of the socket 2, so that the quick connector 3 moves along the axial direction of the socket 2 to be inserted into the guide groove 22 and moves to one end of the card slot 21 in the guide groove 22, and the quick connector 3 moves along the circumferential direction of the socket 2 so that the buckle portion 32 is buckled and connected in the card slot 21.

[0057] When the quick connector device is installed, the quick connector 3 moves in the axial direction of the socket 2 toward each other, so that the buckle portion 32 is inserted into the guide groove 22 and moves to the end of the slot 21 in the guide groove 22; then it moves along the circumferential direction of the socket 2, so that the buckle portion 32 is buckled and connected in the slot 21, thereby realizing the connection between the quick connector 3 and the socket 2, and the plug 1 and the socket 2 are plugged into each other. When the quick connector device is disassembled, the quick connector 3 moves in the circumferential direction of the socket 2, so that the buckle portion 32 moves to the end of the slot 21 located in the guide groove 22; then the quick connector 3 and the plug 1 both move in the axial direction of the socket 2 away from each other, so that the buckle portion 32 is separated from the slot 21 and then from the guide groove 22, thereby realizing the disconnection between the quick connector 3 and the socket 2, and the disconnection between the plug 1 and the socket 2.

[0058] The guide groove 22 has a guiding function, and is used to guide the buckle portion 32 into the slot 21, so as to achieve accurate alignment for installation and removal; and installation and removal can be achieved only by axial movement and circumferential rotation, which is very convenient and fast to use, saving time and effort. At the same time, the structure is simple and the processing and manufacturing are very convenient.

[0059] The outer peripheral surface of the socket 2 also has a positioning annular groove 23, and the through opening 31 has a positioning protrusion 35. The positioning annular groove 23 is connected to the guide groove 22. The positioning protrusion 35 moves along the axial direction of the socket 2 and is inserted into the guide groove 22 and moves into the positioning annular groove 23 in the guide groove 22. The positioning protrusion 35 moves along the circumferential direction of the socket 2 so that the positioning protrusion 35 is restricted to move in the positioning annular groove 23. The positioning annular groove 23 continuously and uninterruptedly surrounds the outer peripheral surface of the socket 2. When the quick connector device is installed, the positioning protrusion 35 first moves along the axial direction so that it moves from the guide groove 22 to the positioning annular groove 23, and then rotates along the circumferential direction so that the positioning protrusion 35 rotates in the positioning annular groove 23. The positioning annular groove 23 restricts the positioning protrusion 35 so that the positioning protrusion 35 can only rotate in the positioning annular groove 23 without causing displacement and dislocation, thereby achieving high rotation stability of the quick connector 3 and improving the electrical connection stability of the quick connector device. At the same time, the structure is simple and the processing and manufacturing are convenient.

[0060] The outer peripheral surface of the socket 2 has a plurality of protruding blocks 24 protruding outward, and the plurality of protruding blocks 24 are arranged at intervals so that a guide groove 22 is formed between any two adjacent protruding blocks 24, and the positioning ring groove 23 is located between the clamping groove 21 and the protruding blocks 24. The guide groove 22 is machined and manufactured by the plurality of protruding blocks 24, and the structure is simple and the manufacturing is very convenient.

[0061] The quick connector device also includes a snap ring 5. The inner wall surface of the quick connector 3 and the outer peripheral surface of the plug 1 are provided with snap ring grooves 13. The snap ring 5 extends into the two snap ring grooves 13, so that the plug 1 and the quick connector 3 are rotatably connected through the snap ring 5. The snap ring 5 enables the plug 1 and the quick connector 3 to rotate relative to each other, effectively avoiding the occurrence of offset and misalignment, and providing higher stability.

[0062] The inner wall surface of the quick connector 3 has an arc-shaped limit groove 34, and the outer surface of the plug 1 has a limit block 12, which extends into the arc-shaped limit groove 34 and can rotate in the arc-shaped limit groove 34. The arc-shaped limit groove 34 is located at one end of the quick connector 3 facing the plug 1 and is located in the through opening 31. When the quick connector 3 and the plug 1 are connected to each other through the clamp 5, the limit block 12 extends into the arc-shaped limit groove 34 and can rotate in the arc-shaped limit groove 34. When the buckle portion 32 is located at the connection between the slot 21 and the guide slot 22, the limit block 12 is located at the end of the arc limit slot 34 and abuts against the side wall of one end of the arc limit slot 34, so that the limit block 12 can only rotate along the other end of the arc limit slot 34 in the arc limit slot 34. At the same time, the buckle portion 32 will also rotate in the slot 21 from the opening of the slot 21; when the limit block 12 abuts against the side wall of the other end of the arc limit slot 34, it indicates that the buckle portion 32 has moved to the bottom of the slot 21, so that the buckle portion 32 is accurately positioned in the slot 21, the connection stability is high, and it is very convenient to use.
