[0015] Preferably, one end of the rotating shaft is rotatably connected with the inner wall of the empty groove, torsion springs are sleeved on the outer sides of the rotating shafts, a hook strip is arranged on the lower side of the fixing rod plate, and the hook strip is slidably installed through the second coupler.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, the staff holds coupler 1 and aligns the guide rod with the perforation and inserts it. As coupler 1 gradually approaches coupler 2, coupler 1 drives spring 1, the ball seat, the ball, and electric contact disk 2 to approach coupler 2 synchronously until electric contact disk 2 contacts electric contact disk 1. Electric contact disk 2 drives the ball and the ball seat to adaptively compress spring 1 to complete the coupling. At the same time, the fixed hook plate also approaches and inserts into the fixed hook groove. When the inclined surface of the fixed hook plate contacts the border of the fixed hook groove, it will be subjected to a squeezing force, driving the two sides of the fixed hook plate to slide and approach each other on coupler 2, compressing spring 3. Until the fixed hook plate is completely inserted into the fixed hook groove, spring 3 pushes the two sides of the fixed hook plate to reset, completing the locking and fixing of the connection between coupler 1 and coupler 2, ensuring the connection stability between coupler 1 and coupler 2.

[0017] 2. In the present invention, the provided limit ring can ensure that the surfaces of electric contact disk 2 and electric contact disk 1 that approach each other are always in stable contact without sliding or deviation, guaranteeing the stability of the electrical connection. During disassembly, only need to press the buckle grooves on the fixed hook plate simultaneously, driving the two sides of the fixed hook plate to approach each other synchronously, compressing spring 3, and the fixed hook plate can be disengaged from the fixed hook groove. Both installation and disassembly are convenient.

[0018] 3. In the present invention, the provided guide rod and perforation facilitate improving the connection accuracy between coupler 1 and coupler 2, avoiding manual alignment and wasting time, and improving the connection efficiency between coupler 1 and coupler 2.

[0019] 4. In the present invention, when coupler 1 approaches coupler 2, it also drives the elastic pressing strip to move synchronously. Before electric contact disk 1 contacts electric contact disk 2, the elastic pressing strip squeezes the pressing plate, and the pressing plate drives link 1 to slide into coupler 2 internally, compressing spring 2 and the airbag. The gas in the airbag sprays out from the nozzle hole, facilitating the pre-cleaning of the dust on the surfaces of electric contact disk 1 and electric contact disk 2 that approach each other. The cleaned and fallen dust will fall from the lower opening of the limit ring, ensuring the stability when electric contact disk 1 and electric contact disk 2 conduct electricity and contact, and avoiding the situation of poor contact caused by dust.

[0020] 5. In the present invention, when the connected coupler 1 and coupler 2 are subjected to a large external pulling force, causing coupler 1 and coupler 2 to deviate in different directions, the provided spring 1 will adaptively deform in the front, back, left, and right directions, and cooperate with the ball to adaptively roll in the ball seat, facilitating the stable fitting of electric contact disk 2 and electric contact disk 1 all the time, ensuring the electrical connection stability between coupler 1 and coupler 2.

[0021] 6. In the present invention, when the guide rod is inserted into the through hole, the upper guide rod will contact and push the inclined surface of the fixed inclined plate to rise. The fixed inclined plate drives the second connecting rod to slide upward on the support plate, compressing the fourth spring. When the fixed groove passes under the fixed inclined plate, the fourth spring drives the fixed inclined plate and the second connecting rod to reset. The lower end of the fixed inclined plate abuts and fits against the upper end of the fixed groove. When the first coupler and the second coupler are connected and the second electric contact plate and the first electric contact plate are about to contact, pulling the hook bar upward drives the fixed rod plate to slide upward on the movable plate, compressing the fifth spring. At this time, the lower end of the fixed rod plate will separate from the movable plate. After the first electric contact plate and the second electric contact plate are in contact and fit, the fixed hole plate on the second electric contact plate will move between the fixed rod plate and the movable plate. Release the hook bar, and the fifth spring drives the fixed rod plate and the hook bar to reset. The fixed rod plate is inserted through and fixed in the fixed hole plate. The fixed rod plate, the fixed hole plate, and the movable plate are all made of conductive materials, contact each other, and form an electrical connection. When the first coupler and the second coupler are subjected to excessive external force, causing the fixed hook plate and the fixed hook groove to deform and separate, the guide rod slides out of the through hole. The cooperation of the set fixed inclined plate and the fixed groove limits the connection between the first coupler and the second coupler again, avoiding the separation of the first coupler and the second coupler.

[0022] 7. In the present invention, when the first electric contact plate and the second electric contact plate are separated and the fixed hole plate and the fixed rod plate are already integrated, it will pull the fixed rod plate, the movable plate, and the wire to disengage synchronously in the direction of the first coupler. At the same time, the wire will adaptively loosen a certain length from the roller, driving the roller and the rotating shaft to rotate adaptively in the empty groove, compressing the torsion spring. At this time, the second electric contact plate, the fixed hole plate, the fixed rod plate, the movable plate, the wire, the roller, the rotating shaft, and the first electric contact plate form an electrical connection, thus ensuring that under the condition that the first coupler and the second coupler are subjected to a large external force impact from the outside, a stable electrical connection can still be ensured, greatly ensuring the connection stability between the couplers.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0026] Refer to Figures 1-11, A coupler connector with stable connection, including coupler 1, and a coupler 2 is provided on the right side of the coupler 1; there is also a connection mechanism for connecting and communicating the coupler 1 and the coupler 2. The connection mechanism includes an electric contact plate 1 installed fixedly inside the left end of the coupler 2. An electric contact plate 2 is provided corresponding to the electric contact plate 1 on the right side of the coupler 1. A limit ring 1 is fixedly installed corresponding to the electric contact plate 2 on the outer side of the electric contact plate 1. A spherical ball 3 is fixedly installed in the middle of the left end of the electric contact plate 2. A ball seat 4 is movably installed on the left side of the spherical ball 3. A first spring 5 is fixedly installed at the left end of the ball seat 4. The left end of the first spring 5 is fixedly installed on the coupler 1. Nozzle holes 6 are equidistantly opened on the inner side of the limit ring 1. An airbag 7 is communicated inside the nozzle hole 6. The airbag 7 is fixedly installed on the front and back sides inside the coupler 2. A pressure plate 8 is fixedly installed at the left end of the airbag 7. A first connecting rod 9 is fixedly installed at the right end of the pressure plate 8. The right end of the first connecting rod 9 penetrates and is slidably installed on the coupler 2. A second spring 10 is sleeved on the outer side of the first connecting rod 9. The left and right ends of the second spring 10 are fixedly connected to the pressure plate 8 and the coupler 2 respectively. An elastic pressing strip 11 is fixedly installed on the right end of the coupler 1 corresponding to the pressure plate 8. Fixed hook plates 12 are symmetrically slidably installed on the upper and lower sides of the left side of the coupler 2. A third spring 13 is fixedly installed between the fixed hook plates 12. And a fixed hook groove 14 is opened on the front end of the coupler 1 corresponding to the fixed hook plates 12; During operation, the operator holds coupler 1 and aligns the guide rod 17 with the perforation 18 and inserts it. As coupler 1 gradually approaches coupler 2, coupler 1 drives the first spring 7, ball seat 6, ball 5, and the second electrical contact plate 4 to approach coupler 2 synchronously until the second electrical contact plate 4 contacts the first electrical contact plate 3. The second electrical contact plate 4 drives the ball 5 and the ball seat 6 to adaptively compress the first spring 7 to complete the coupling. At the same time, the fixed hook plate 14 also approaches and inserts into the fixed hook groove 16. When the inclined surface of the fixed hook plate 14 contacts the frame of the fixed hook groove 16, it will be subjected to a squeezing force, driving the two fixed hook plates 14 to slide and approach each other on coupler 2, compressing the third spring 15. Until the fixed hook plate 14 is completely inserted into the fixed hook groove 16, the third spring 15 pushes the two fixed hook plates 14 to reset, completing the locking and fixing of the connection between coupler 1 and coupler 2, ensuring the connection stability between coupler 1 and coupler 2. The provided limit ring 301 can ensure that the surfaces of the second electrical contact plate 4 and the first electrical contact plate 3 that approach each other are always in stable contact without sliding or deviation, ensuring the stability of the electrical connection. During disassembly, only need to press the buckle grooves on the fixed hook plate 14 simultaneously, driving the two fixed hook plates 14 to approach each other synchronously, compressing the third spring 15, and the fixed hook plate 14 can be disengaged from the fixed hook groove 16. Both installation and disassembly are convenient. The provided guide rod 17 and perforation 18 are convenient for improving the connection accuracy between coupler 1 and coupler 2, avoiding manual alignment and wasting time, and improving the connection efficiency between coupler 1 and coupler 2. When coupler 1 approaches coupler 2, it also drives the elastic pressing strip 13 to move synchronously. Before the first electrical contact plate 3 contacts the second electrical contact plate 4, the elastic pressing strip 13 squeezes the pressing plate 10, and the pressing plate 10 drives the first connecting rod 11 to slide into coupler 2, compressing the second spring 12 and the airbag 9. The gas in the airbag 9 is ejected from the nozzle hole 8, which is convenient for cleaning the dust on the surfaces of the first electrical contact plate 3 and the second electrical contact plate 4 that approach each other in advance. The cleaned and fallen dust will fall from the lower opening of the limit ring 301, ensuring the stability of the conductive contact between the first electrical contact plate 3 and the second electrical contact plate 4 and avoiding the situation of poor contact caused by dust. When the connected coupler 1 and coupler 2 are subjected to a large external pulling force, causing coupler 1 and coupler 2 to deviate in different directions, the provided first spring 7 will adaptively deform in the front, back, left, and right directions, and cooperate with the ball 5 to adaptively roll in the ball seat 6, which is convenient for keeping the second electrical contact plate 4 and the first electrical contact plate 3 in stable contact all the time, ensuring the stability of the electrical connection between coupler 1 and coupler 2.

[0027] As an embodiment of the present invention, a safeguard mechanism is further provided for stably connecting the first coupler 1 and the second coupler 2. The safeguard mechanism includes guide rods 17 fixedly installed at the four corners of the right end of the first coupler 1. Corresponding to the guide rods 17, through holes 18 are respectively opened at the four corners of the left end of the second coupler 2. Fixed inclined plates 19 are respectively arranged inside the upper through holes 18. Fixed grooves 1901 are respectively opened at the upper ends of the guide rods 17 corresponding to the fixed inclined plates 19. A second connecting rod 20 is fixedly installed at the upper end of the fixed inclined plate 19. A support plate 21 is slidably installed through the upper end of the second connecting rod 20. The support plate 21 is fixedly installed at the upper end of the second coupler 2. A fourth spring 22 is sleeved on the outer side of the second connecting rod 20. The upper and lower ends of the fourth spring 22 are respectively fixedly connected to the support plate 21 and the fixed inclined plate 19. A fixed hole plate 23 is fixedly installed at the right end of the second electric contact plate 4. An empty groove 24 is opened at the left end of the first electric contact plate 3. A fixed rod plate 25 corresponding to the fixed hole plate 23 is arranged inside the empty groove 24. A movable plate 26 is slidably installed through the middle of the fixed rod plate 25. The upper and lower ends of the movable plate 26 are slidably connected to the first electric contact plate 3. The lower end of the fixed rod plate 25 is abutted and attached to the movable plate 26. A fifth spring 27 is fixedly installed at the upper end of the fixed rod plate 25. The upper end of the fifth spring 27 is fixedly installed on the movable plate 26. A wire 28 is fixedly installed at the right end of the movable plate 26. The other end of the wire 28 is fixedly wound with a roller 29. Rotating shafts 30 are respectively fixedly installed at the front and rear ends of the roller 29. The wire 28, the movable plate 26, and the fixed rod plate 25 are all electrically connected. One end of the rotating shaft 30 is rotatably connected to the inner wall of the empty groove 24. A torsion spring 31 is sleeved on the outer side of the rotating shaft 30. A hook strip 32 is arranged below the fixed rod plate 25. The hook strip 32 is slidably installed through the second coupler 2; During operation, when the guide rod 17 is inserted into the perforation 18, the upper guide rod 17 will contact and push the inclined surface of the fixed inclined plate 19 to rise. The fixed inclined plate 19 drives the second connecting rod 20 to slide and rise on the support plate 21, compressing the fourth spring 22. When the fixed groove 1901 passes below the fixed inclined plate 19, the fourth spring 22 drives the fixed inclined plate 19 and the second connecting rod 20 to reset. The lower end of the fixed inclined plate 19 abuts and fits against the upper end of the fixed groove 1901. When the first coupler 1 and the second coupler 2 are connected and the second electric contact disk 4 and the first electric contact disk 3 are about to contact, pulling the hook bar 32 upward drives the fixed rod plate 25 to slide upward on the movable plate 26, compressing the fifth spring 27. At this time, the lower end of the fixed rod plate 25 will separate from the movable plate 26. After the first electric contact disk 3 and the second electric contact disk 4 are in contact and fit, the fixed hole plate 23 on the second electric contact disk 4 will move between the fixed rod plate 25 and the movable plate 26. Release the hook bar 32, and the fifth spring 27 drives the fixed rod plate 25 and the hook bar 32 to reset. The fixed rod plate 25 is inserted through and fixed in the fixed hole plate 23. The fixed rod plate 25, the fixed hole plate 23, and the movable plate 26 are all made of conductive materials, contact each other, and form an electrical connection. When the first coupler 1 and the second coupler 2 are subjected to excessive external force, causing the fixed hook plate 14 and the fixed hook groove 16 to deform and separate, the guide rod 17 slides out of the perforation 18. The cooperation of the set fixed inclined plate 19 and the fixed groove 1901 limits the connection of the first coupler 1 and the second coupler 2 again, preventing the first coupler 1 and the second coupler 2 from separating. At the same time, the first electric contact disk 3 and the second electric contact disk 4 separate. The fixed hole plate 23 is already integrated with the fixed rod plate 25, and it will pull the fixed rod plate 25, the movable plate 26, and the wire 28 to disengage synchronously in the direction of the first coupler 1. At the same time, the wire 28 will adaptively loosen a certain length from the roller 29, driving the roller 29 and the rotating shaft 30 to rotate adaptively in the empty groove 24, compressing the torsion spring 31. At this time, the second electric contact disk 4, the fixed hole plate 23, the fixed rod plate 25, the movable plate 26, the wire 28, the roller 29, the rotating shaft 30, and the first electric contact disk 3 form an electrical connection, thus ensuring that the first coupler 1 and the second coupler 2 can still ensure a stable electrical connection under the condition of being impacted by a large external force from the outside, greatly ensuring the connection stability between the couplers.

[0028] Working principle: When the present invention is in use, the staff holds the first coupler 1 and aligns the guide rod 17 with the perforation 18 and inserts it. As the first coupler 1 gradually approaches the second coupler 2, the first coupler 1 drives the first spring 7, the ball seat 6, the ball 5 and the second electric contact plate 4 to approach the second coupler 2 synchronously until the second electric contact plate 4 contacts the first electric contact plate 3. The second electric contact plate 4 drives the ball 5 and the ball seat 6 to adaptively compress the first spring 7 to complete the coupling and adaptively compress the first spring 7. At the same time, the fixed hook plate 14 will also approach and insert into the fixed hook groove 16. When the inclined surface of the fixed hook plate 14 contacts the frame of the fixed hook groove 16, it will be subjected to a squeezing force, driving the two sides of the fixed hook plate 14 to slide and approach each other on the second coupler 2, compressing the third spring 15. Until the fixed hook plate 14 is completely inserted into the fixed hook groove 16, the third spring 15 pushes the two sides of the fixed hook plate 14 to reset, completing the locking and fixing of the connection between the first coupler 1 and the second coupler 2, ensuring the connection stability between the first coupler 1 and the second coupler 2. The provided limit ring 301 can ensure that the surfaces of the second electric contact plate 4 and the first electric contact plate 3 that approach each other are always in stable contact without sliding or deviation, ensuring the stability of the electrical connection. During disassembly, only need to press the buckle grooves on the fixed hook plate 14 simultaneously, driving the two sides of the fixed hook plate 14 to approach each other synchronously, compressing the third spring 15, and the fixed hook plate 14 can be disengaged from the fixed hook groove 16. Both assembly and disassembly are convenient. The provided guide rod 17 and perforation 18 are convenient for improving the connection accuracy between the first coupler 1 and the second coupler 2, avoiding manual alignment and wasting time, and improving the connection efficiency between the first coupler 1 and the second coupler 2. When the first coupler 1 approaches the second coupler 2, it will also drive the elastic pressing strip 13 to move synchronously. Before the first electric contact plate 3 contacts the second electric contact plate 4, the elastic pressing strip 13 squeezes the pressing plate 10, and the pressing plate 10 drives the first connecting rod 11 to slide into the second coupler 2, compressing the second spring 12 and the airbag 9. The gas in the airbag 9 is ejected from the nozzle hole 8, which is convenient for cleaning the dust on the surfaces of the first electric contact plate 3 and the second electric contact plate 4 that approach each other in advance. The cleaned and fallen dust will fall from the lower opening of the limit ring 301, ensuring the stability when the first electric contact plate 3 and the second electric contact plate 4 conduct electricity and contact, and avoiding the situation of poor contact caused by dust. When the connected first coupler 1 and second coupler 2 are subjected to a large external pulling force, causing the first coupler 1 and the second coupler 2 to deviate in different directions, the provided first spring 7 will adaptively deform in the front, back, left and right directions, and cooperate with the ball 5 to adaptively roll in the ball seat 6, which is convenient for keeping the second electric contact plate 4 and the first electric contact plate 3 always in stable contact, ensuring the electrical connection stability between the first coupler 1 and the second coupler 2;When the guide rod 17 is inserted into the through hole 18, the upper guide rod 17 will contact and push the inclined surface of the fixed inclined plate 19 to rise. The fixed inclined plate 19 drives the second connecting rod 20 to slide and rise on the support plate 21, compressing the fourth spring 22. When the fixed groove 1901 passes below the fixed inclined plate 19, the fourth spring 22 drives the fixed inclined plate 19 and the second connecting rod 20 to reset. The lower end of the fixed inclined plate 19 abuts and fits against the upper end of the fixed groove 1901. When the first coupler 1 and the second coupler 2 are connected and the second electric contact plate 4 and the first electric contact plate 3 are about to contact, pulling the hook bar 32 upward drives the fixed rod plate 25 to slide upward on the movable plate 26, compressing the fifth spring 27. At this time, the lower end of the fixed rod plate 25 will separate from the movable plate 26. After the first electric contact plate 3 and the second electric contact plate 4 are in contact and fit, the fixed hole plate 23 on the second electric contact plate 4 will move between the fixed rod plate 25 and the movable plate 26. Release the hook bar 32, and the fifth spring 27 drives the fixed rod plate 25 and the hook bar 32 to reset. The fixed rod plate 25 is inserted through and fixed in the fixed hole plate 23. The fixed rod plate 25, the fixed hole plate 23, and the movable plate 26 are all made of conductive materials, contact each other, and form an electrical connection. When the first coupler 1 and the second coupler 2 are subjected to excessive external forces, causing the fixed hook plate 14 and the fixed hook groove 16 to deform and separate, the guide rod 17 slides out of the through hole 18. The cooperation of the set fixed inclined plate 19 and the fixed groove 1901 limits the connection between the first coupler 1 and the second coupler 2 again, preventing the first coupler 1 and the second coupler 2 from separating. At the same time, the first electric contact plate 3 and the second electric contact plate 4 separate. The fixed hole plate 23 is already integrated with the fixed rod plate 25, and it will pull the fixed rod plate 25, the movable plate 26, and the wire 28 to disengage synchronously in the direction of the first coupler 1. At the same time, the wire 28 will adaptively loosen a certain length from the roller 29, driving the roller 29 and the rotating shaft 30 to rotate adaptively in the empty groove 24, compressing the torsion spring 31. At this time, the second electric contact plate 4, the fixed hole plate 23, the fixed rod plate 25, the movable plate 26, the wire 28, the roller 29, the rotating shaft 30, and the first electric contact plate 3 form an electrical connection, thus ensuring that when the first coupler 1 and the second coupler 2 are subjected to a large external force impact from the outside, a stable electrical connection can still be ensured, greatly ensuring the connection stability between the couplers.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
