DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

The movement of the pressing sleeve 804 drives the four push blocks 805 to move, and the movement of two push blocks 805 will respectively conflict with the movement of two limit blocks 806. The fourth spring 807 contracts, and when one side of the push block 805 conflicts with the sliding sleeve 802, the pressing sleeve 804 cannot be pushed further. At this time, the sliding sleeve 802 can be pulled, and the sliding sleeve 802 will conflict with the limit block 806 during the movement and continue to move toward the connection The internal movement of the column 801 releases the pressing sleeve 804 while pulling the sleeve 802 and then continues to pull the sleeve 802. Next, in the process of pulling the sleeve 802, the two limit blocks 806 will be engaged with the sleeve 802 again under the action of the fourth spring 807, so that the sleeve 802 cannot continue to move. At this time, since the sleeve 802 moves from the inside of the charging pile body 9 to the outside of the charging pile body 9, the charging pile body 9 will not resist the wires wrapped around the sleeve 802, so it is more convenient to take the wires, and it is also convenient to wind the wires, thereby effectively improving the convenience of operation.

[0023] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9As shown, the lifting structure 2 includes a slide 201 and a motor 202, two slides 201 are fixedly connected inside the placement groove 1, and the same placement platform 206 is slidably connected between the two slides 201, and the motor 202 is installed at the bottom end of the slide 201. A screw rod 203 is rotatably connected to the slide 201, and the bottom end of the screw rod 203 is fixedly connected to the output shaft of the motor 202. A connecting sleeve 204 is threadedly connected to the screw rod 203, and the connecting sleeve 204 is rotatably connected to the placement platform 206. A charging pile body 9 is placed on the top of the placement platform 206, and a clamping structure 3 is provided on the slide 201, and a plurality of clamping grooves 205 are provided on the connecting sleeve 204. The top of the placement platform 206 is provided with The groove 207 has a trumpet-shaped top, and the bottom end of the charging pile body 9 is located inside the groove 207. The plurality of slots 205 are distributed in a circular array about the rotation center of the connection sleeve 204. The widths of the two ends of the cross section of the connection sleeve 204 are smaller than the width in the middle. The positioning structure 3 includes a pressure ring 301 and a stopper 302. Two pressure rings 301 are slidably connected to the placement table 206. Two stoppers 302 are fixedly connected to the bottom end of the pressure ring 301. The stoppers 302 are slidably connected to the placement table 206. The bottom end of the stopper 302 abuts against a stopper 303, which is slidably connected to the placement table 206. One end of the two stoppers 303 is respectively connected to the two slots 205. The first spring 304 is in contact with the block 303 and the placement table 206, the bottom end of the cross section of the block 302 is a trapezoidal structure, one end of the cross section of the block 303 is a trapezoidal structure, the top of the pressure ring 301 extends to the outside of the placement table 206, the shielding structure 4 includes a sleeve rod 401 and a slide column 402, four sleeve rods 401 are fixedly connected to the placement table 206, the sleeve rod 401 is internally slidably connected to the slide column 402, the tops of the four slide columns 402 are fixedly connected to the same blocking cover 404, the outer sleeve of the slide column 402 is provided with a second spring 405, one end of the second spring 405 is in contact with the shielding cover 404 and the other end is in contact with the sleeve rod 401, and the slide column 402 is on the A pressure rod 403 is fixedly connected, that is, the placement slot 1 can be buried underground when in use. Since the charging pile body 9 is located inside the placement slot 1, the charging pile body 9 can be prevented from being exposed to the external environment for a long time, thereby reducing the probability of damage to the charging pile body 9. When the new energy vehicle needs to be charged, the two motors 202 can be started at the same time. The output shaft of the motor 202 rotates to drive the screw rod 203 to rotate. Since the ends of the two clamping blocks 303 are engaged with two of the clamping slots 205 at this time, the connection sleeve 204 and the placement platform 206 cannot rotate. At this time, the rotation of the screw rod 203 will drive the connection sleeve 204 to move in the axial direction of the screw rod 203. The simultaneous movement of the two connection sleeves 204 will drive the placement platform 206 to move.By setting two slide seats 201, the placement platform 206 is guided to move. The movement of the placement platform 206 will drive the charging pile body 9 to move, so that the charging pile body 9 moves from the inside of the placement slot 1 to the outside of the placement slot 1. At this time, the new energy vehicle can be charged through the charging pile body 9. The shielding cover 404 and the water retaining frame 7 can prevent rainwater from entering the inside of the placement slot 1. When a heavy object is located on the top of the shielding cover 404, the shielding cover 404 will move under the action of the gravity of the heavy object. The movement of the shielding cover 404 drives the four sliding columns 402 to slide inside the four sleeve rods 401 respectively, and the four second springs 405 contract. The movement of the sliding column 402 will drive the pressure rod 403 to move, and the pressure rod 403 moves. The movement of the pressing ring 301 will resist the movement of the pressing ring 301, and the movement of the pressing ring 301 will drive the movement of the resisting block 302. The movement of the resisting block 302 will resist the movement of the card block 303 away from the card slot 205. The first spring 304 will contract, and when the bottom end of the shielding cover 404 contacts the top end of the placement slot 1, the movement will stop. At this time, the end of the card block 303 is not engaged with the card slot 205. Therefore, when the screw rod 203 rotates, it will drive the connecting sleeve 204 to rotate without changing the position of the placement platform 206. Therefore, it can prevent the shielding cover 404 from overturning a person or a car during the movement, and at the same time prevent the motor 202 from bearing a large load, and avoid damage to the motor 202, thereby effectively improving the safety and stability of use.

[0024] Specifically, Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the fixed structure 6 includes a card plate 601 and a slide plate 603, two slide plates 603 are slidably connected to the placement platform 206, and the slide plate 603 is fixedly connected to the card plate 601. The ends of the two card plates 601 are respectively engaged with the two sides of the charging pile body 9, and one of the card plates 601 is rotatably connected to a rotating block 602, and the slide plate 603 is fixedly connected to a rack 604. The bottom end of the placement platform 206 is rotatably connected to a gear 605, and the two sides of the gear 605 are respectively meshed with the two racks 604. A third spring 606 is fixedly connected between the slide plate 603 and the placement platform 206. The counterweight structure 5 includes a connecting block 501 and a guide wheel 502. Four connecting blocks 501 are fixedly connected to the placement slot 1, and the connecting blocks 501 are rotatably connected to guide wheels 502, and connecting ropes 503 are wound around the guide wheels 502. One end of the connecting rope 503 is fixedly connected to the placement platform 206, and the other end of the connecting rope 503 is fixedly connected to the counterweight 504. A guide column 505 is fixedly connected to the connecting block 501, and the counterweight 504 is slidably connected to the guide column 505, that is, during the movement of the placement platform 206, the counterweight 504 will slide on the guide column 505. Since the counterweight 504 and the placement platform 206 are connected by the connecting rope 503, and the connecting rope 503 is wound around the guide wheel 502, the counterweight 504 can slide on the guide column 505. The gravity of the weight block 504 can be converted into an upward pulling force on the placement table 206, so that a part of the gravity of the charging pile body 9 can be offset by the gravity of the counterweight block 504, thereby saving energy and labor. At the same time, when the charging pile body 9 is damaged and needs to be disassembled for maintenance, the charging pile body 9 can be moved from the inside of the placement slot 1 to the outside of the placement slot 1, and then one of the card plates 601 is pulled, and the movement of one of the card plates 601 will drive one of the slide plates 603 to move. Since the two slide plates 603 are fixedly connected with the rack 604 and the rack 604 is meshed with the two sides of the gear 605, when one of the slide plates 603 moves, it will drive the other slide plate 603 to move in the opposite direction. , so that the other card plate 601 also moves in the opposite direction, so that the two card plates 601 move away from the charging pile body 9 at the same time. When the ends of the two card plates 601 are not engaged with the charging pile body 9, the rotating block 602 can be rotated ninety degrees. At this time, the card plate 601 is released. Under the support of the rotating block 602, the third spring 606 will not stretch to make the card plate 601 engage with the charging pile body 9 again, thereby avoiding the need to pull the card plate 601 by hand during the disassembly process, thereby effectively improving the convenience of operation. Next, the charging pile body 9 can be removed from the placement table 206. At this time, the rapid disassembly of the charging pile body 9 is completed, which is convenient for the inspection and maintenance of the charging pile body 9.

[0025] When the present invention is in use, the placement slot 1 can be buried underground. Since the charging pile body 9 is located inside the placement slot 1, the charging pile body 9 can be prevented from being exposed to the external environment for a long time, thereby reducing the probability of damage to the charging pile body 9. When it is necessary to charge the new energy vehicle, the two motors 202 can be started at the same time. The output shaft of the motor 202 rotates to drive the screw rod 203 to rotate. Since the ends of the two clamping blocks 303 are engaged with two of the clamping slots 205 at this time, the connection sleeve 204 and the placement platform 206 cannot rotate. At this time, the rotation of the screw rod 203 will drive the connection sleeve 204 to move in the axial direction of the screw rod 203. , the simultaneous movement of the two connecting sleeves 204 will drive the placement table 206 to move. The two slide seats 201 are provided to guide the movement of the placement table 206. During the movement of the placement table 206, the counterweight 504 will slide on the guide column 505. Since the counterweight 504 and the placement table 206 are connected by a connecting rope 503, and the connecting rope 503 is wound around the guide wheel 502, the gravity of the counterweight 504 can be converted into an upward pulling force on the placement table 206, so that the gravity of a part of the charging pile body 9 can be offset by the gravity of the counterweight 504, thereby achieving energy saving and labor saving. The movement of the placement table 206 will The charging pile body 9 will be driven to move, so that the charging pile body 9 moves from the inside of the placement groove 1 to the outside of the placement groove 1. At this time, the new energy vehicle can be charged through the charging pile body 9. The shielding cover 404 and the water retaining frame 7 can prevent rainwater from entering the inside of the placement groove 1. When a heavy object is located at the top of the shielding cover 404, the shielding cover 404 will move under the action of the gravity of the heavy object. The movement of the shielding cover 404 drives the four sliding columns 402 to slide inside the four sleeve rods 401 respectively, and the four second springs 405 contract. The movement of the sliding column 402 will drive the pressure rod 403 to move, and the movement of the pressure rod 403 will resist the movement of the pressure ring 301. The pressure ring 301 moves The movement of the stopper 302 will cause the stopper 303 to move away from the slot 205, and the first spring 304 will contract. When the bottom end of the shielding cover 404 contacts the top end of the placement slot 1, the movement will stop. At this time, the end of the block 303 is not engaged with the slot 205. Therefore, when the screw rod 203 rotates, the connection sleeve 204 will be driven to rotate without changing the position of the placement platform 206. Therefore, the shielding cover 404 can be prevented from overturning a person or a car during the movement, and the motor 202 can be prevented from being subjected to a large load, thereby preventing the motor 202 from being damaged, thereby effectively improving the safety and stability of use. During use, excess wires can be wrapped around the sleeve 802, and the two baffles 803 can resist the wrapped wires, thereby preventing the wrapped wires from falling off the sleeve 802, thereby effectively improving the stability of use. By wrapping excess wires around the sleeve 802, excess wires can be prevented from being entangled around the charging pile body 9, thereby avoiding adverse effects on the lifting and lowering of the charging pile body 9. When the charging plug is needed to charge the new energy vehicle, the charging pile body 9 is first moved from the inside of the placement slot 1 to the outside of the placement slot 1, and then the pressing sleeve 804 is pressed. The movement of the pressing sleeve 804 drives the four push blocks 805 to move, and the movement of the two push blocks 805 will respectively resist the movement of the two limit blocks 806, and the fourth spring 807 contracts. When one of the push blocks 805 When the sliding sleeve 802 contacts the side and the sliding sleeve 802, the pressing sleeve 804 cannot be pushed further, and the sliding sleeve 802 can be pulled at this time. The sliding sleeve 802 will contact the limiting block 806 during the movement and continue to move toward the inside of the connecting column 801. In the process of pulling the sliding sleeve 802, the pressing sleeve 804 is released and the sliding sleeve 802 is continued to be pulled. Next, in the process of pulling the sliding sleeve 802, the two limiting blocks 806 will be engaged with the sliding sleeve 802 again under the action of the fourth spring 807, so that the sliding sleeve 802 cannot move further. At this time, since the sliding sleeve 802 moves from the inside of the charging pile body 9 to the outside of the charging pile body 9, the charging pile body 9 will not resist the wires wound on the sliding sleeve 802, so it is more convenient to take the wires, and it is also convenient to wind the wires, thereby effectively improving the convenience of operation; When the charging pile body 9 is damaged and needs to be disassembled for maintenance, the charging pile body 9 can be moved from the inside of the placement slot 1 to the outside of the placement slot 1, and then one of the card plates 601 is pulled, and the movement of one of the card plates 601 will drive one of the slide plates 603 to move. Since the two slide plates 603 are fixedly connected with the rack 604 and the rack 604 is meshed with the two sides of the gear 605, when one of the slide plates 603 moves, it will drive the other slide plate 603 to move in the opposite direction, so that the other card plate 601 also moves in the opposite direction, so that the two card plates 601 move simultaneously. When the ends of the two clamping plates 601 are not engaged with the charging pile body 9, the rotating block 602 can be rotated ninety degrees. At this time, the clamping plate 601 is released. Under the support of the rotating block 602, the third spring 606 will not stretch to make the clamping plate 601 engage with the charging pile body 9 again, thereby avoiding the need to hold the clamping plate 601 by hand during the disassembly process, thereby effectively improving the convenience of operation. Next, the charging pile body 9 can be removed from the placing table 206. At this time, the rapid disassembly of the charging pile body 9 is completed, thereby facilitating the inspection and maintenance of the charging pile body 9.
