[0002] With the continuous advancement of technology and the growing awareness of environmental protection, charging boxes are becoming increasingly popular. As a device that provides power to various electronic devices, charging boxes play an increasingly important role in modern society. In order to protect the internal structure of the charging box and prevent accidents, it is necessary to lock the charging box door. Therefore, a charging box door lock is needed.

[0003] Most existing charging boxes use padlocks to lock the doors. However, padlocks exposed to the elements for extended periods are susceptible to rust and corrosion from rain and dust, affecting their normal use and consequently compromising the overall safety of the charging box. Furthermore, some locks, due to the large size of the charging box doors, only restrict and fix the door to the outer shell near the lock itself, neglecting to simultaneously restrict and fix the top and bottom of the door to the charging box shell. This results in a loose seal between the top and bottom of the door and the charging box shell, posing a safety hazard and leading to poor overall locking and sealing performance.

With the gear 19 and tooth 23, the rotation of the handle 13 can drive the first extension bar 24 to move up or down and the second extension bar 25 to move down or up, thus locking and limiting or opening the door body 4 and the charging box body 2. With the sealing ring 27, the sealing effect between the door body 4 and the charging box body 2 can be improved. With the limit block 26, the first extension bar 24 and the second extension bar 25 can be limited to ensure the vertical movement of the first extension bar 24 and the second extension bar 25.

[0028] In this embodiment

[0029] When using the door lock of this charging box, the ventilation window 3 allows for heat dissipation inside the charging box body 2, ensuring the normal operation of the internal structure. The protective cover 5 protects the charging gun 6 and also allows for the winding and placement of the connecting wires of the charging gun 6. With the charging gun 6 in place, new energy vehicles can be charged. The control panel 7 and the main switch 8 allow for control of the internal structure of the charging box body 2 and the charging gun 6. The wire trough 9 allows for the laying of connecting wires inside the charging box body 2, preventing tangled wires and facilitating subsequent maintenance by the user. When it is necessary to seal and lock the door body 4 and the charging box body 2, the user closes the door body 4 and the charging box body 2, and then turns the handle 13 clockwise. The rotation of the handle 13 drives the locking pin 18 to rotate, and the rotation of the locking pin 18 drives the gear 19 and the locking plate 20 to rotate. The rotation of the locking plate 20 can change the locking plate 20 from a vertical state to a horizontal state, thereby completing the initial limiting between the door body 4 and the charging box body 2. At the same time, under the limiting of the gear 23, the rotation of the gear 19 drives the first connecting strip 21 to move upward and the second connecting strip 22 to move downward. The upward movement of the first connecting strip 21 drives the first extension strip 24 to move upward and the second extension strip 22 to move downward. The downward movement of 22 causes the second extension bar 25 to move downward, simultaneously completing the limiting of the top and bottom of the door body 4 and the charging box body 2. Then, the handle 13 is folded down and placed into the lock case 11. The handle 13 causes the locking fastener 16 and the torsion spring 17 to rotate. With the help of the key, the lock cylinder 15 is rotated, which can press one end of the locking fastener 16. At this time, the locking fastener 16 and the handle 13 are locked together, completing the locking of the handle 13. Finally, the padlock is passed through the fixing ring 12 and locked, realizing the sealing and locking between the door body 4 and the charging box body 2, achieving a good locking effect. With the setting of the sealing ring 27, the gap between the door body 4 and the charging box body 2 can be improved. The sealing effect is achieved by limiting the first extension bar 24 and the second extension bar 25 under the setting of the limiting block 26, ensuring the vertical movement of the first extension bar 24 and the second extension bar 25. When opening the main body of the box door 4, the user inserts the key into the lock cylinder 15 and turns it to release the pressure on the fastener 16. Under the reset force of the torsion spring 17, the fastener 16 resets to an inclined state and pushes the bottom end of the handle 13 out from the lock shell 11. The user flips the handle 13 upward and turns it counterclockwise to release the limitation of the first extension bar 24, the second extension bar 25 and the locking piece 20 on the main body of the box door 4, thereby completing the opening of the main body of the box door 4.

[0030] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
