Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a charging pile and method with electronic leakage protection technology, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a charging pile with electronic leakage protection technology, comprising: a charging pile body, a charging head, the charging head is fixedly mounted on the surface of the charging pile body, and the charging head is used to charge electric vehicles; a rain shield, the rain shield is fixedly mounted on the surface of the charging pile body, and the rain shield is used to prevent rainwater from entering the charging head; a leakage monitor, the leakage monitor is fixedly mounted on the surface of the charging pile body, and the leakage monitor is used to monitor the flow of current and detect whether there is abnormal leakage; a charging pile body is provided with a There is a rotating slot, a fixed block is fixedly installed on the surface of the charging head, a trapezoidal skateboard is slidably installed on the inner wall of the charging pile body, a U-shaped pull rod is fixedly installed on the surface of the trapezoidal skateboard, a fixed plate is fixedly installed on the surface of the U-shaped pull rod, a trapezoidal plate is slidably installed on the surface of the charging pile body, and a protective device and a heat dissipation device are provided inside the charging pile body to prevent rainwater from entering. Insert the fixed block into the rotating slot, and then rotate the charging head. The rotation of the charging head will drive the fixed block to rotate, and the rotation of the fixed block will contact the trapezoidal skateboard, and the fixed block will push the trapezoidal skateboard to move away from the fixed block.

[0007] According to the above technical solution, a triangular slide is slidably installed on the inner wall of the charging pile body, a push rod is fixedly installed on the surface of the triangular slide, and a triangular block is fixedly installed on the bottom of the trapezoidal plate. When the push rod moves away from the fixed block, the triangular block moves away from the fixed plate, and when the triangular block moves away from the fixed plate, the trapezoidal plate moves away from the fixed plate.

[0008] According to the above technical solution, a No. 1 spring is arranged between the charging pile body and the trapezoidal skateboard. When the fixed block is out of contact with the trapezoidal skateboard, the elastic force of the No. 1 spring itself will drive the trapezoidal skateboard to reset. A No. 2 spring is arranged between the charging pile body and the trapezoidal plate. When the trapezoidal plate is out of contact with the fixed plate, the elastic force of the No. 2 spring itself will drive the trapezoidal plate to reset. A No. 3 spring is arranged between the charging pile body and the triangular skateboard. When the fixed block triangular skateboard is out of contact, the elastic force of the No. 3 spring itself will drive the triangular skateboard to reset.

[0009] A method for using a charging pile with electronic leakage protection technology includes the following steps: Step 1: After the charger is connected to the car, the leakage monitor monitors the current flow during charging and detects whether there is abnormal leakage. When the system detects leakage, the charging pile automatically cuts off the power supply to prevent current leakage, thereby ensuring the safety of users. Step 2: When charging is completed, insert the fixed block into the rotating slot, and then rotate the charging head. The rotation of the charging head drives the fixed block to rotate. The fixed block rotates and contacts the trapezoidal slide. The fixed block pushes the trapezoidal slide to move away from the fixed block. When the fixed block is separated from the trapezoidal slide, the No. 1 spring drives the trapezoidal slide to reset. The trapezoidal slide resets to limit the fixed block. The limiting method makes the charging head less likely to fall off, preventing the charging head from being pulled and collided and falling directly to the ground, which may easily cause damage to the charging head. Step 3: When the charging head needs to be used, manually pull the U-shaped pull rod away from the fixed block. The movement of the U-shaped pull rod away from the fixed block drives the trapezoidal slide to disengage from the limit of the fixed block, so that the charging head can be taken out normally. At the same time, the movement of the U-shaped pull rod away from the fixed block drives the fixed plate to move away from the fixed block. The fixed plate moves away from the fixed block and contacts the trapezoidal plate. The fixed plate pushes the trapezoidal plate to move away from the fixed plate. When the fixed plate is out of contact with the trapezoidal plate, the No. 2 spring drives the trapezoidal plate to reset. The trapezoidal plate resets to limit the fixed plate. There is no need to pull the U-shaped pull rod by hand all the time, which is more convenient to operate. Step 4: The push rod moves away from the fixed block, pushing the triangular block away from the fixed plate. The triangular block moves away from the fixed plate, driving the trapezoidal plate to move away from the fixed plate. The trapezoidal plate moves away from the fixed plate to release the limit on the fixed plate, so that the U-shaped pull rod and the trapezoidal slide are reset, which is convenient for the subsequent continuous limit of the fixed block to ensure the stability of the charging head. According to the above technical solution, a protective device and a heat dissipation device for preventing rainwater from entering are provided inside the charging pile body. The protective device includes a circular ring, a hollow slip ring and a slide groove. The hollow slip ring will move away from the circular ring when it is reset. The charging pile body interface is protected by the hollow slip ring moving away from the circular ring. The circular ring is fixedly installed on the inner wall of the charging pile body, the hollow slip ring is slidably installed on the surface of the circular ring, and the slide groove is opened on the surface of the circular ring.

[0010] According to the above technical solution, an L-shaped frame is fixedly installed on the surface of the hollow slip ring, a semicircular plate is slidably installed on the surface of the slide groove, a connecting seat is fixedly installed on the top of the semicircular plate, a rotating plate is rotatably installed on the inner wall of the connecting seat, and the end of the rotating plate away from the connecting seat is rotatably installed on the inner wall of the L-shaped frame. When the rotating plate moves away from the circular ring, it will squeeze the connecting seat to move downward, and the downward movement of the connecting seat will drive the semicircular plate to move downward. The internal interface of the charging pile body is blocked by the two semicircular plates moving towards each other.

[0011] According to the above technical solution, a No. 4 spring is arranged between the hollow slip ring and the circular ring. When the hollow slip ring loses the extrusion of the charging head, the elastic force of the No. 4 spring itself will drive the hollow slip ring to reset. A No. 5 spring is arranged between the slide groove and the semicircular plate. When the L-shaped frame is reset, the semicircular plate loses the extrusion and will reset under the elastic force of the No. 5 spring itself.

[0012] According to the above technical solution, the heat dissipation device includes a connecting rod, a pulley, a trapezoidal block and a heat dissipation baffle. The hollow slip ring moves in the direction away from the circular ring, driving the connecting rod to move in the direction away from the circular ring. The movement of the connecting rod in the direction away from the circular ring will drive the pulley to move in the direction away from the circular ring. The movement of the pulley in the direction away from the circular ring will break away from the extrusion of the trapezoidal block. A heat dissipation groove is provided on the surface of the charging pile body. The connecting rod is fixedly installed on the surface of the hollow slip ring. The pulley is rotatably installed on the inner wall of the connecting rod. The heat dissipation baffle is slidably installed on the inner wall of the heat dissipation groove. The trapezoidal block is fixedly installed on the surface of the heat dissipation baffle.

[0013] According to the above technical solution, a U-shaped frame is fixedly installed on the surface of the heat dissipation baffle, a fixed rod is fixedly installed on the surface of the heat dissipation baffle, and a dust shield is fixedly installed on the surface of the fixed rod. When the heat dissipation baffle moves away from the pulley, the fixed rod moves away from the pulley, and the fixed rod moves away from the pulley, which drives the dust shield away from the pulley.

[0014] According to the above technical solution, a No. 6 spring is arranged between the heat dissipation baffle and the heat dissipation groove. When the trapezoidal block loses the squeezing of the pulley, the elastic force of the No. 6 spring itself will drive the heat dissipation baffle to reset, and the pulley contacts the surface of the trapezoidal block.

[0015] The present invention provides a charging pile with electronic leakage protection technology and a method thereof. It has the following beneficial effects: (1) In this invention, when the charging head is connected to the car, the leakage monitor will monitor the flow of current during charging and detect whether there is abnormal leakage. When the system detects leakage, the charging pile body will automatically cut off the power supply to avoid current leakage, thereby ensuring the safety of the user. When charging is completed, the fixed block is inserted into the rotating slot, and then the charging head is rotated. The rotation of the charging head will drive the fixed block to rotate, and the rotation of the fixed block will contact the trapezoidal slide, and the fixed block will push the trapezoidal slide away from the fixed block. When the fixed block is separated from the trapezoidal slide, the No. 1 spring will drive the trapezoidal slide to reset. The reset of the trapezoidal slide will limit the fixed block, and the limiting method will prevent the charging head from falling off easily, and prevent the charging head from being pulled and directly falling to the ground, which may easily cause damage to the charging head.

[0016] (2) This invention does not require the user to pull the U-shaped pull rod by hand all the time, making the operation more convenient. After contacting the limit of the fixed block, the charging head is rotated in the opposite direction. The reverse rotation of the charging head will drive the fixed block to rotate in the opposite direction. During the reverse rotation of the fixed block, the triangular slide plate will be contacted, and the fixed block will push the triangular slide plate to move away from the fixed block. The limit on the fixed plate is released by moving the trapezoidal plate away from the fixed plate, so that the U-shaped pull rod and the trapezoidal slide plate are reset, which is convenient for the subsequent continuous limit of the fixed block to ensure the stability of the charging head.

[0017] (3) In this invention, when the charging head is taken out, the hollow slip ring loses its compression and resets under the elastic force of the No. 4 spring. The hollow slip ring resets and moves away from the circular ring. The interface of the charging pile body is protected by the movement of the hollow slip ring away from the circular ring. At the same time, when the charging head is inserted into the charging pile body, the hollow slip ring guides the charging head to prevent the deviation of the charging head when it is inserted into the charging pile body, which may cause damage to the charging head. The internal interface of the charging pile body is blocked by the two semicircular plates moving towards each other, which prevents the inclined rain from entering the internal interface of the charging pile body when charging the car on rainy days, causing corrosion of the interface of the charging pile body, which may cause leakage risk and pose a safety hazard.

[0018] (4) This invention improves the heat dissipation effect by opening the heat dissipation vent during charging, thereby preventing the internal voltage from being too high during charging, which may cause the device to overheat and affect the normal operation of the device. When the charging head is returned to its original position, the heat dissipation baffle will block the heat dissipation vent to prevent water vapor in the air from entering the interior of the charging pile body. The entry of water may cause corrosion or short circuit of components such as circuit boards and interfaces. At the same time, the dust shield will push impurities accumulated inside the heat dissipation vent away from the pulley to prevent impurities from accumulating inside the heat dissipation vent and affecting the normal heat dissipation of the device.

[0023] A triangular slide 10 is slidably installed on the inner wall of the charging pile body 1, a push rod 11 is fixedly installed on the surface of the triangular slide 10, and a triangular block 12 is fixedly installed on the bottom of the trapezoidal plate 9. The trapezoidal plate 9 is moved away from the fixed plate 8 to release the limitation on the fixed plate 8, so that the U-shaped pull rod 7 and the trapezoidal slide 6 are reset, which is convenient for the subsequent continuous limitation of the fixed block 5 to ensure the stability of the charging head 2.

[0024] A No. 1 spring is arranged between the charging pile body 1 and the trapezoidal skateboard 6. When the fixed block 5 is out of contact with the trapezoidal skateboard 6, the elastic force of the No. 1 spring itself will drive the trapezoidal skateboard 6 to reset. A No. 2 spring is arranged between the charging pile body 1 and the trapezoidal plate 9. When the trapezoidal plate 9 is out of contact with the fixed plate 8, the elastic force of the No. 2 spring itself will drive the trapezoidal plate 9 to reset. A No. 3 spring is arranged between the charging pile body 1 and the triangular skateboard 10. When the fixed block 5 and the triangular skateboard 10 are out of contact, the elastic force of the No. 3 spring itself will drive the triangular skateboard 10 to reset.

[0025] A method for using a charging pile with electronic leakage protection technology includes the following steps: Step 1: After the charging head 2 is connected to the car, the leakage monitor 4 monitors the flow of current during charging and detects whether there is abnormal leakage. When the system detects leakage, the charging pile body 1 automatically cuts off the power supply to prevent current leakage, thereby ensuring the safety of users; Step 2: When charging is completed, insert the fixed block 5 into the rotating slot, and then rotate the charging head 2. The rotation of the charging head 2 drives the fixed block 5 to rotate, and the fixed block 5 rotates to contact the trapezoidal slide 6. The fixed block 5 pushes the trapezoidal slide 6 to move away from the fixed block 5. When the fixed block 5 is separated from the trapezoidal slide 6, the No. 1 spring drives the trapezoidal slide 6 to reset. The trapezoidal slide 6 resets to limit the fixed block 5. The limiting method makes the charging head 2 not easy to fall off, and prevents the charging head 2 from being pulled and collided and falling directly to the ground, which may easily cause damage to the charging head 2. Step 3: When the charging head 2 needs to be used, the U-shaped pull rod 7 is manually pulled to move in the direction away from the fixed block 5. The U-shaped pull rod 7 moves in the direction away from the fixed block 5, driving the trapezoidal slide 6 to disengage from the limit of the fixed block 5, so that the charging head 2 can be taken out normally. At the same time, the U-shaped pull rod 7 moves in the direction away from the fixed block 5, driving the fixed plate 8 to move in the direction away from the fixed block 5. The fixed plate 8 moves in the direction away from the fixed block 5 and contacts the trapezoidal plate 9. The fixed plate 8 pushes the trapezoidal plate 9 to move in the direction away from the fixed plate 8. When the fixed plate 8 is out of contact with the trapezoidal plate 9, the No. 2 spring drives the trapezoidal plate 9 to reset. The trapezoidal plate 9 resets to limit the fixed plate 8. There is no need to pull the U-shaped pull rod 7 by hand all the time, and the operation is more convenient. Step 4: The push rod 11 moves away from the fixed block 5, pushing the triangular block 12 to move away from the fixed plate 8. The triangular block 12 moves away from the fixed plate 8, driving the trapezoidal plate 9 to move away from the fixed plate 8. The trapezoidal plate 9 moves away from the fixed plate 8 to release the limitation on the fixed plate 8, so that the U-shaped pull rod 7 and the trapezoidal slide 6 are reset, which is convenient for the subsequent continuous limitation of the fixed block 5 to ensure the stability of the charging head 2.

[0026] When this embodiment works: after the charging head 2 is connected to the car, the leakage monitor 4 will monitor the flow of current during charging and detect whether there is abnormal leakage. When the system detects leakage, the charging pile body 1 will automatically cut off the power supply to avoid current leakage, thereby ensuring the safety of users. When charging is completed, the fixed block 5 is inserted into the rotating slot, and then the charging head 2 is rotated. The rotation of the charging head 2 will drive the fixed block 5 to rotate. The rotation of the fixed block 5 will contact the trapezoidal slide 6, and the fixed block 5 will push the trapezoidal slide 6 to move away from the fixed block 5. When the fixed block 5 is separated from the trapezoidal slide 6, the fixed block 5 will be pushed away from the trapezoidal slide 6. After that, the No. 1 spring will drive the trapezoidal slide 6 to reset, and the reset of the trapezoidal slide 6 will limit the fixed block 5, so that the charging head 2 is not easy to fall off by limiting, and the charging head 2 is prevented from being pulled and directly falling to the ground, which may easily cause damage to the charging head 2. At the same time, when the charging head 2 needs to be used, the U-shaped pull rod 7 is manually pulled in the direction away from the fixed block 5. The movement of the U-shaped pull rod 7 in the direction away from the fixed block 5 will drive the trapezoidal slide 6 to break away from the limit of the fixed block 5, so that the charging head 2 can be taken out normally. At the same time, the movement of the U-shaped pull rod 7 in the direction away from the fixed block 5 will drive the fixed plate 8 to move away from the fixed block 5. When the fixing plate 8 moves in the direction away from the fixing block 5, the fixing plate 8 will contact the trapezoidal plate 9, and the fixing plate 8 will push the trapezoidal plate 9 to move in the direction away from the fixing plate 8. When the fixing plate 8 is out of contact with the trapezoidal plate 9, the second spring will drive the trapezoidal plate 9 to reset, and the reset of the trapezoidal plate 9 will limit the fixing plate 8. There is no need to pull the U-shaped pull rod 7 by hand all the time, which makes the operation more convenient. At the same time, after releasing the limit on the fixing block 5, the charging head 2 is rotated in the opposite direction. The reverse rotation of the charging head 2 will drive the fixing block 5 to rotate in the opposite direction. During the reverse rotation of the fixing block 5, it will contact the triangular slide plate 10, and the fixed block 5 will push the triangular slide plate 10 moves in the direction away from the fixed block 5, the triangular slide 10 moving in the direction away from the fixed block 5 will drive the push rod 11 to move in the direction away from the fixed block 5, the push rod 11 moving in the direction away from the fixed block 5 will push the triangular block 12 to move in the direction away from the fixed plate 8, the triangular block 12 moving in the direction away from the fixed plate 8 will drive the trapezoidal plate 9 to move in the direction away from the fixed plate 8, and the trapezoidal plate 9 is moved in the direction away from the fixed plate 8 to release the limitation on the fixed plate 8, so that the U-shaped pull rod 7 and the trapezoidal slide 6 are reset, which is convenient for the subsequent continuous limitation of the fixed block 5 to ensure the stability of the charging head 2.

[0027] See also Figures 1-8On the basis of the above embodiment, in another embodiment of the present invention, a protective device and a heat dissipation device for preventing rainwater from entering are provided inside the charging pile body 1. The protective device includes a circular ring 131, a hollow slip ring 132 and a slide groove 137. The circular ring 131 is fixedly mounted on the inner wall of the charging pile body 1, the hollow slip ring 132 is slidably mounted on the surface of the circular ring 131, and the slide groove 137 is provided on the surface of the circular ring 131. The hollow slip ring 132 guides the charging head 2 to prevent deviation when the charging head 2 is inserted into the charging pile body 1.

[0028] An L-shaped frame 133 is fixedly installed on the surface of the hollow slip ring 132, and a semicircular plate 136 is slidably installed on the surface of the slide groove 137. A connecting seat 135 is fixedly installed on the top of the semicircular plate 136, and a rotating plate 134 is rotatably installed on the inner wall of the connecting seat 135. The end of the rotating plate 134 away from the connecting seat 135 is rotatably installed on the inner wall of the L-shaped frame 133 to prevent slanted rain from entering the internal interface of the charging pile body 1 when charging the car on rainy days, causing corrosion of the interface of the charging pile body 1, which may cause the risk of leakage and pose a safety hazard.

[0029] A No. 4 spring is arranged between the hollow slip ring 132 and the circular ring 131. When the hollow slip ring 132 loses the extrusion of the charging head 2, the elastic force of the No. 4 spring itself will drive the hollow slip ring 132 to reset. A No. 5 spring is arranged between the slide groove 137 and the semicircular plate 136. When the L-shaped frame 133 is reset, the semicircular plate 136 loses the extrusion and will reset under the elastic force of the No. 5 spring itself.

[0030] The heat dissipation device includes a connecting rod 141, a pulley 142, a trapezoidal block 143 and a heat dissipation baffle 144. A heat dissipation groove is opened on the surface of the charging pile body 1. The connecting rod 141 is fixedly installed on the surface of the hollow slip ring 132. The pulley 142 is rotatably installed on the inner wall of the connecting rod 141. The heat dissipation baffle 144 is slidably installed on the inner wall of the heat dissipation groove. The trapezoidal block 143 is fixedly installed on the surface of the heat dissipation baffle 144. The heat dissipation port will be opened by resetting the heat dissipation baffle 144. The heat dissipation effect is improved by opening the heat dissipation port during charging to prevent the internal voltage from being too high during charging, causing the equipment to overheat and affecting the normal operation of the equipment. When the charging head 2 is returned to its position, the heat dissipation baffle 144 will block the heat dissipation port to prevent water vapor in the air from entering the interior of the charging pile body 1. The entry of moisture may cause corrosion or short circuit of components such as circuit boards and interfaces.

[0031] A U-shaped frame 145 is fixedly installed on the surface of the heat dissipation baffle 144, a fixed rod 146 is fixedly installed on the surface of the heat dissipation baffle 144, and a dust shield 147 is fixedly installed on the surface of the fixed rod 146. The dust shield 147 pushes impurities accumulated inside the heat dissipation port away from the pulley 142 to prevent the accumulation of impurities from affecting the normal heat dissipation of the equipment.

[0032] A No. 6 spring is provided between the heat dissipation baffle 144 and the heat dissipation groove. When the trapezoidal block 143 loses the squeezing of the pulley 142, the elastic force of the No. 6 spring itself will drive the heat dissipation baffle 144 to reset, and the pulley 142 will contact the surface of the trapezoidal block 143.

[0033] When this embodiment is working: after the charging head 2 is taken out, the hollow slip ring 132 loses its extrusion and will reset under the elastic force of the No. 4 spring. The hollow slip ring 132 resets and moves in the direction away from the circular ring 131. The hollow slip ring 132 moves in the direction away from the circular ring 131 to protect the interface of the charging pile body 1. At the same time, when the charging head 2 is inserted into the charging pile body 1, the hollow slip ring 132 will guide the charging head 2 to prevent the deviation of the charging head 2 when it is inserted into the charging pile body 1, which will cause damage to the charging head 2. At the same time, the hollow slip ring 132 moves in the direction away from the circular ring 131, which will drive the L-shaped frame 13 3 moves in the direction away from the ring 131, the L-shaped frame 133 moving in the direction away from the ring 131 will drive the rotating plate 134 to move in the direction away from the ring 131, the rotating plate 134 moving in the direction away from the ring 131 will squeeze the connecting seat 135 to move downward, and the connecting seat 135 moving downward will drive the semicircular plate 136 to move downward. The two semicircular plates 136 move toward each other to block the internal interface of the charging pile body 1, preventing the inclined rain from entering the internal interface of the charging pile body 1 when charging the car on a rainy day, causing corrosion of the interface of the charging pile body 1, which may cause leakage risk and pose a safety hazard.

[0034] The hollow slip ring 132 moves in the direction away from the circular ring 131, driving the connecting rod 141 to move in the direction away from the circular ring 131. The movement of the connecting rod 141 in the direction away from the circular ring 131 will drive the pulley 142 to move in the direction away from the circular ring 131. The movement of the pulley 142 in the direction away from the circular ring 131 will break away from the extrusion of the trapezoidal block 143, so that the heat dissipation baffle 144 is reset under the elastic force of the No. 6 spring. The reset of the heat dissipation baffle 144 will open the heat dissipation port. By opening the heat dissipation port during charging, the heat dissipation effect is improved, and the internal voltage is prevented from being too large during charging, resulting in overheating of the equipment and affecting the normal operation of the equipment. When the charging head 2 is returned to its position, the heat dissipation baffle 144 will block the heat dissipation port to prevent water vapor in the air from entering the interior of the charging pile body 1. The entry of moisture may cause damage to components such as circuit boards and interfaces. Corrosion or short circuit, at the same time, when the connecting rod 141 moves toward the direction close to the ring 131, it will drive the pulley 142 to move toward the direction close to the ring 131, and the pulley 142 moving toward the direction close to the ring 131 will push the trapezoidal block 143 to move away from the pulley 142, and the trapezoidal block 143 moving away from the pulley 142 will drive the heat dissipation baffle 144 to move away from the pulley 142, and the heat dissipation baffle 144 moving away from the pulley 142 will drive the fixing rod 146 away from the pulley 142, and the fixing rod 146 away from the pulley 142 will drive the dust shield 147 away from the pulley 142, and the impurities accumulated inside the heat dissipation port will be pushed out by the dust shield 147 in the direction away from the pulley 142, so as to prevent the accumulation of impurities from affecting the normal heat dissipation of the equipment.

10. A method for using a charging pile with electronic leakage protection technology, using the charging pile with electronic leakage protection technology according to claim 9, characterized in that: The following steps are involved: Step 1: After the charging head (2) is connected to the car, the leakage monitor (4) monitors the flow of current during charging and detects whether there is abnormal leakage. When the system detects leakage, the charging pile body (1) automatically cuts off the power supply to prevent current leakage, thereby ensuring the safety of users; Step 2: When charging is completed, the fixed block (5) is inserted into the rotating card slot, and then the charging head (2) is rotated. The rotation of the charging head (2) drives the fixed block (5) to rotate, and the fixed block (5) rotates and contacts the trapezoidal slide (6). The fixed block (5) pushes the trapezoidal slide (6) to move in a direction away from the fixed block (5). When the fixed block (5) is separated from the trapezoidal slide (6), the No. 1 spring drives the trapezoidal slide (6) to reset. The trapezoidal slide (6) resets and limits the fixed block (5). The limiting makes it difficult for the charging head (2) to fall off, and prevents the charging head (2) from being pulled and collided and directly falling to the ground, which easily causes damage to the charging head (2); Step 3: When the charging head (2) needs to be used, manually pull the U-shaped pull rod (7) to move away from the fixed block (5). The U-shaped pull rod (7) moves in the direction away from the fixed block (5) to drive the trapezoidal slide (6) to break away from the limit of the fixed block (5), so that the charging head (2) can be taken out normally. At the same time, the U-shaped pull rod (7) moves in the direction away from the fixed block (5) to drive the fixed plate (8) to move in the direction away from the fixed block (5). The fixed plate (8) moves in the direction away from the fixed block (5) and contacts the trapezoidal plate (9). The fixed plate (8) pushes the trapezoidal plate (9) to move in the direction away from the fixed plate (8). When the fixed plate (8) breaks away from the contact with the trapezoidal plate (9), the second spring drives the trapezoidal plate (9) to reset. The trapezoidal plate (9) resets to limit the fixed plate (8). There is no need to pull the U-shaped pull rod 7 by hand all the time, and the operation is more convenient. Step 4: The push rod (11) moves in a direction away from the fixed block (5) to push the triangular block (12) to move in a direction away from the fixed plate (8). The triangular block (12) moves in a direction away from the fixed plate (8) to drive the trapezoidal plate (9) to move in a direction away from the fixed plate (8). The trapezoidal plate (9) moves in a direction away from the fixed plate (8) to release the restriction on the fixed plate (8), so that the U-shaped pull rod (7) and the trapezoidal slide (6) are reset, which facilitates the subsequent continuous restriction of the fixed block (5) to ensure the stability of the charging head (2).
