[0038] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present invention: An electrical box door connection structure includes a box body 1 and a rotating box door 3. A plurality of fixed screws 4 are equally spaced and fixedly connected to the rear side of the top end of the box body 1 and the bottom end of the front side of the rotating box door 3. Fixed hinges 5 are threadedly connected to the outer walls of the two left fixed screws 4, and rotating hinges 6 are threadedly connected to the outer walls of the two right fixed screws 4. A limit chute 7 is opened in the middle of the right end of the fixed screw 4. A moving rotating rod 8 is slidably connected to the inner wall of the limit chute 7. The inner wall of the rotating hinge 6 is rotatably connected to the outer wall of the moving rotating rod 8. A damping piece 9 is fixedly connected to the left side of the rotating hinge 6. A resistance spring 10 is fixedly connected to the left side of the damping piece 9. The left end of the resistance spring 10 is fixedly connected to the outer part of the right end of the fixed hinge 5. A fixed lock tooth 11 is fixedly connected to the right side of the rotating hinge 6. A moving lock tooth 12 is fixedly connected to the outer wall of the right side of the moving rotating rod 8. The fixed lock tooth 11 and the moving lock tooth 12 are engaged with each other. An unlocking mechanism 2 is provided at the right end of the moving rotating rod 8;

[0040] Specifically, when it is necessary to unlock the rotating box door 3 of the electric box under normal conditions, the moving lever 8 is pulled outwards by hand. During this process, it is necessary to overcome the elastic force of the resistance spring 10. The resistance spring 10 is in a compressed state under normal conditions. When an outward pulling force is applied to the moving lever 8, the moving lever 8 begins to slide in the limit chute 7, and at the same time drives the moving lock tooth 12 on the right side of its outer wall to gradually move away from the fixed lock tooth 11 on the right side of the rotating hinge 6. The engagement effect between the moving lock tooth 12 and the fixed lock tooth 11 is completely released, so that the rotating box door 3 is no longer locked and can be freely opened. After adjusting the rotating box door 3 to a suitable position, the moving lever 8 is released, so that the resistance spring 10 releases the resistance and engages the moving lock tooth 12 with the fixed lock tooth 11 again, so that the rotating box door 3 will not be accidentally closed due to external forces, preventing potential safety hazards to the operator during work, enabling the operator to concentrate on operating, inspecting or repairing the equipment inside the electric box. When it is necessary to close the rotating box door 3 and re-lock it after completing the relevant operations, the moving lock tooth 12 and the fixed lock tooth 11 are unlocked in the same way as above. The rotating box door 3 is fitted to the box body 1. After releasing the moving lever 8, the resistance spring 10 is no longer stretched by external forces, so that the moving lever 8 slides inwards in the limit chute 7. As the moving lever 8 moves inwards, the moving lock tooth 12 gradually approaches the fixed lock tooth 11, and then the box body 1 and the rotating box door 3 are locked after being closed. During this process, the damping piece 9 plays an important buffering role. The damping piece 9 can slow down the moving speed of the moving lever 8, making the engagement process smoother and avoiding the impact and noise generated by rapid engagement. When the moving lock tooth 12 and the fixed lock tooth 11 are in full contact, they will be tightly engaged together under the continuous action of the resistance spring 10 and automatically locked after closing the box door, providing a reliable guarantee for the normal use of the electric box and the safety of the internal equipment, avoiding the problem that the rotating box door 3 is accidentally closed or opened due to external forces in a specific working environment, thus bringing potential safety hazards to the operator.

[0041] Refer to Figure 2 、 Figure 4 and Figure 5 As shown in FIGS. 9, 10 and 11, the unlocking mechanism 2 includes a connection hole 201. The inner wall of the connection hole 201 is threadedly connected with a connection block 202. The middle of the right end of the connection block 202 is fixedly connected with a pulling rope 203. The pulling rope 203 passes through the inside of the box body 1. A pulley 204 is rotatably connected to each inner bending part of the box body 1. The pulling rope 203 fits on the inner walls of the plurality of pulleys 204. The top end of the pulling rope 203 is fixedly connected with an I-shaped slide rail 205. The middle of the top wall of the I-shaped slide rail 205 is fixedly connected with a manual dial 206. A horizontal chute 207 is formed in the front side of the top wall of the box body 1. The bottom of the I-shaped slide rail 205 slides inside the horizontal chute 207;

[0042] Specifically, a stable connection structure is formed by the threaded connection between the connection hole 201 and the connection block 202. When it is necessary to unlock the electric box door, manually move the manual dial 206. Since the manual dial 206 is fixedly connected to the I-shaped slide rail 205, pushing the manual dial 206 will drive the I-shaped slide rail 205 to slide within the horizontal chute 207. The movement of the I-shaped slide rail 205 will pull the pulling rope 203 fixedly connected thereto. The pulling rope 203 passes through the inside of the box body 1 and fits against the inner wall of the pulley 204 at multiple bending points. The function of the pulley 204 is to change the pulling direction of the pulling rope 203, enabling the pulling rope 203 to smoothly transmit the pulling force. As the pulling rope 203 is pulled, the connection block 202 will receive an outward pulling force. Since the connection block 202 is fixedly connected to the moving rotating rod 8, the movement of the connection block 202 will drive the moving rotating rod 8 to move outward. When the moving rotating rod 8 moves outward, the moving lock teeth 12 on the right side of its outer wall gradually disengage from the engagement state with the fixed lock teeth 11 on the right side of the rotating hinge 6, thus realizing the unlocking function. When the manual dial 206 is released, under the action of the resistance spring 10, the moving rotating rod 8 will automatically move inward and return to the locked state, achieving convenient unlocking of the connection structure of the electric box door and providing a reliable and easy-to-operate method for users when they need to open the electric box door.

[0043] Referring to Figure 1 and Figure 5 , at the front top end of the rotating box door 3, two dial slots 13 are provided. When the rotating box door 3 is closed, the two manual dials 206 are respectively contained within the two dial slots 13; on the left and right sides of the manual dial 206, a plurality of anti-slip strips 14 are fixedly connected, and the plurality of anti-slip strips 14 are arranged equidistantly from top to bottom; at the middle of the front top end of the rotating box door 3, an inverted cone buckle 15 is fixedly connected, and at the middle of the front end of the top wall of the box body 1, a catch 16 is fixedly installed, and the catch 16 and the catch 16 are opened and closed with each other;

[0044] Specifically, when the rotating box door 3 is closed, the manual dial 206 is contained within the dial slot 13, making the overall structure more compact and avoiding collisions or accidental touches caused by the protrusion of the manual dial 206. The anti-slip strips 14 on both sides of the manual dial 206 are arranged equidistantly from top to bottom. When operating the manual dial 206, the friction between the fingers and the manual dial 206 can be increased, making it more convenient and accurate for users to perform the unlocking operation, not easy to slip, and improving the stability of the operation. When the rotating box door 3 is closed, the inverted cone buckle 15 and the catch 16 are engaged with each other, providing an additional locking function for the electric box door and enhancing the stability and safety when the box door is closed.

[0045] Referring to Figure 1 , Figure 2 and Figure 4, a sealing strip 17 is fixedly connected to the outer wall of the front side of the rotating box door 3, a sealing groove 18 is formed on the outer side of the top wall of the box body 1, and the sealing strip 17 and the sealing groove 18 are engaged with each other when the rotating box door 3 is closed; a rotating groove 19 is formed on the right side of the connecting block 202, and the shape of the rotating groove 19 is a regular hexagon; the four corners of the bottom wall of the box body 1 are all designed with a smooth shape, and both the box body 1 and the rotating box door 3 are designed symmetrically;

[0046] Specifically, when the rotating box door 3 is closed, the sealing strip 17 and the sealing groove 18 are engaged with each other to form a good sealing effect, which can effectively prevent external impurities such as dust and water vapor from entering the inside of the electric box, protect the electrical equipment inside the electric box from the influence of the external environment, improve the reliability and service life of the equipment. The regular hexagon rotating groove 19 on the right side of the connecting block 202 can facilitate the operation of using tools to install, disassemble or adjust the connecting block 202, improving the convenience of installation and maintenance. The smooth design of the four corners of the bottom wall of the box body 1 reduces the collision damage that may be caused by sharp corners, improving the safety of use. The symmetrical design of the box body 1 and the rotating box door 3 is not only more beautiful in appearance, but also more stable in structure, enabling the electric box to better withstand various external forces during use and ensuring the overall performance of the electric box.

[0047] Working principle: When it is necessary to unlock the rotating cabinet door 3 of the electrical box under normal conditions of the electrical box, pull the movable rotating rod 8 outwards by hand. During this process, it is necessary to overcome the elastic force of the resistance spring 10. The resistance spring 10 is in a compressed state under normal conditions. When an outward pulling force is applied to the movable rotating rod 8, the movable rotating rod 8 begins to slide in the limit sliding groove 7, and at the same time drives the movable locking tooth 12 on the right side of its outer wall to gradually move away from the fixed locking tooth 11 on the right side of the rotating hinge 6. The engagement effect between the movable locking tooth 12 and the fixed locking tooth 11 is completely released, so that the rotating cabinet door 3 is no longer locked and can be freely opened. After adjusting the rotating cabinet door 3 to the appropriate position, release the movable rotating rod 8 to enable the resistance spring 10 to release resistance and re-engage the movable locking tooth 12 with the fixed locking tooth 11, so that the rotating cabinet door 3 will not be accidentally closed due to external forces, preventing potential safety hazards to the operator during work, enabling the operator to concentrate on operating, inspecting or repairing the equipment inside the electrical box. When it is necessary to close the rotating cabinet door 3 and re-lock it after completing the relevant operations, unlock the movable locking tooth 12 and the fixed locking tooth 11 in the same way as above, fit the rotating cabinet door 3 with the box body 1, and after releasing the movable rotating rod 8, the resistance spring 10 is no longer subjected to the tensile force of external forces, causing the movable rotating rod 8 to slide inwards in the limit sliding groove 7. As the movable rotating rod 8 moves inwards, the movable locking tooth 12 gradually approaches the fixed locking tooth 11, and then the box body 1 and the rotating cabinet door 3 are locked after being closed. During this process, the damping piece 9 plays an important buffering role. The damping piece 9 can slow down the moving speed of the movable rotating rod 8, making the engagement process smoother and avoiding the impact and noise generated by rapid engagement. When the movable locking tooth 12 and the fixed locking tooth 11 are in full contact, they will be tightly engaged together under the continuous action of the resistance spring 10 and automatically locked after closing the cabinet door, providing reliable guarantee for the normal use of the electrical box and the safety of the internal equipment;

[0048] Furthermore, the connecting hole 201 and the connecting block 202 are threadedly connected to form a stable connection structure. When the electrical box door needs to be unlocked, the manual paddle 206 is manually toggled. Since the manual paddle 206 is fixedly connected to the I-shaped slide rail 205, pushing the manual paddle 206 will drive the I-shaped slide rail 205 to slide in the horizontal slide groove 207. The movement of the I-shaped slide rail 205 will pull the pulling rope 203 fixedly connected thereto. The pulling rope 203 runs through the interior of the box body 1 and fits the inner wall of the pulley 204 at multiple bends. The function of the pulley 204 is to change the pulling force of the pulling rope 203. The force direction enables the pulling rope 203 to smoothly transmit the pulling force. As the pulling rope 203 is pulled, the connecting block 202 will be subjected to the outward pulling force. Since the connecting block 202 is fixedly connected to the movable rotating rod 8, the movement of the connecting block 202 will drive the movable rotating rod 8 to move outward. When the movable rotating rod 8 moves outward, the movable locking tooth 12 on the right side of its outer wall gradually disengages from the engaging state with the fixed locking tooth 11 on the right side of the rotating hinge 6, thereby realizing the unlocking function. When the manual paddle 206 is released, under the action of the resistance spring 10, the movable rotating rod 8 will automatically move inward and return to the locked state.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
