[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Examples, such as Figures 1-4As shown, a photovoltaic grid-connected cabinet that is easy to assemble includes a grid-connected cabinet body 1. Cabinet doors 11 are provided on both the front and rear sides of the grid-connected cabinet body 1. A partition 12 is provided inside the grid-connected cabinet body 1. For the grid-connected cabinet body 1, the internal partition 12 divides the interior of the grid-connected cabinet body 1, providing space on both the front and rear sides for easy installation of electrical components, thus improving its functionality. Furthermore, two partitions 12 can be provided in the grid-connected cabinet body 1, and a heat dissipation component can be installed between them to improve the rationality of the grid-connected cabinet body 1's design. This embodiment aims to solve the connection problem between two grid-connected cabinet bodies 1, specifically: two grid-connected cabinet bodies 1 are arranged vertically. A plug-in rod 2 is located on the upper inner side of the lower grid-connected cabinet body 1. Corresponding to the plug-in rod 2, a locking mechanism 3 is located inside the upper grid-connected cabinet body 1. That is, when an additional grid-connected cabinet body 1 needs to be added, the lower grid-connected cabinet body 1 is first placed in a suitable position on the ground, and then the newly added grid-connected cabinet body 1 is placed on top of the existing one, with the locking mechanism 3 aligned with the plug-in rod 2. The locking mechanism 3 then connects the upper and lower grid-connected cabinet bodies 1 together, ensuring the stability of the connection and preventing displacement, thus meeting usage requirements. Furthermore, to ensure the connection effect between the cabinets, the locking mechanism 3 includes a mounting plate 31, with a locking mechanism 31 located on top of the mounting plate 31. A socket 32 ​​is provided between two mounting plates 31, and a housing 33 is provided within the housing 33. A locking rod 34 with a wedge-shaped end is provided within the housing 33. An adjusting rod 35 is provided within the housing 33 between the two locking rods 34. The adjusting rod 35 includes a frustum-shaped upper part of a retaining block 351, and a screw 352 is provided below the retaining block 351. When the adjusting rod 35 is driven, its screw 352 can rotate vertically relative to the housing 33, thereby allowing the retaining block 351 to act on the locking rod 34, causing it to move horizontally and ensuring the locking action. Specifically, the upper grid-connected cabinet body 1 is placed on the lower grid-connected cabinet body 1, with the socket 32 ​​and the plug-in rod 2 facing each other. When it is necessary to connect two adjacent grid-connected cabinet bodies 1, force is applied to the adjusting rod 35 to rotate it, so that the lower part of the pressing block 351 acts on the locking rod 34, and the locking rod 34 moves to both sides and is inserted into the plug-in rod 2 through the plug-in sleeve 32, thereby completing the convenient connection of the two adjacent grid-connected cabinet bodies 1, achieving a locking effect, preventing them from shifting, greatly improving the functionality of the device and meeting the usage requirements; furthermore, a lifting moving mechanism 4 is provided on the outside of the lower grid-connected cabinet body 1. The lifting moving mechanism 4 can not only achieve stable placement of the grid-connected cabinet, but also move and adjust its position, greatly improving the practicality of the device and fully meeting the usage requirements;

[0020] In the above process: Utilizing the established locking mechanism 3, when the upper grid-connected cabinet body 1 is placed on the lower grid-connected cabinet body 1, the locking mechanism 3 corresponds to the plug-in rod 2, and drives the adjusting rod 35 in the locking mechanism 3, causing the locking rod 34 to insert into the plug-in rod 2, thus connecting the upper and lower grid-connected cabinet bodies 1 and securing them together to prevent displacement. This greatly improves the functionality of the device and meets usage requirements. Utilizing the established lifting and moving mechanism 4, on the one hand, it can achieve stable placement of the grid-connected cabinet body 1, improving its stability; on the other hand, it can also… The device can be switched from a stable placement state to a mobile state, making it convenient for users to move and adjust its position. In other words, the established lifting and moving mechanism 4 can both stably place the grid-connected cabinet and move and adjust its position, greatly improving the practicality of the device and fully meeting the usage requirements. The device is reasonably designed, simple in structure, easy to process, and can easily add cabinets, especially in the vertical direction, optimizing the spatial planning of the installation location. At the same time, it improves the functionality of the device, makes the moving and adjusting process more convenient, reduces the difficulty of operation, and meets the usage requirements.

[0021] To further improve the rationality of the device design, the end face of the locking rod 34 near the outer side of the adjusting rod 35 is designed with an inclination. A circular hole 321 is provided in the plug sleeve 32 corresponding to the locking rod 34, and a plug hole 21 is provided in the plug rod 2 corresponding to the circular hole 321. Specifically, the inclination end face of the adjusting rod 35 is adapted to the outer periphery of the abutment block 351. When the adjusting rod 35 is rotated, the outer periphery of the abutment block 351 corresponds to the end face of the locking rod 34, which facilitates the locking action. The circular hole 321 and the plug hole 21 provide the prerequisite for the locking rod 34 to connect the plug sleeve 32 and the plug rod 2, ensuring the stability of the connection effect and meeting the usage requirements.

[0022] To ensure the locking effect of the locking mechanism 3, a keyway 321 is provided inside the housing 33. A slot 341 is provided inside the locking rod 34 corresponding to the keyway 321. A limit rod 36 is provided inside the keyway 321. A retaining spring 37 is provided on one side of the limit rod 36 and is located inside the slot 341. Specifically, the keyway 321 and the slot 341 are of the same specifications, and the limit rod 36 is provided inside the housing 33. When the locking rod 34 extends outward under the action of the adjusting rod 35, When the locking function is implemented, the locking rod 34 compresses the clamping spring 37 at the slot 341. When it is necessary to loosen the locking mechanism 3, the adjusting rod 35 is rotated in the opposite direction. The compressed clamping spring 37 extends and retracts, and drives the locking rod 34 to move towards the adjusting rod 35, so that it resets and waits for the next locking action. The establishment of the above device enables the locking rod 34 to have a reset function, which greatly improves the functionality of the device and meets the usage requirements.

[0023] To facilitate convenient adjustment of the position of the grid-connected cabinet body 1, the lifting and moving mechanism 4 includes a mounting frame 41. A sleeve rod 42 is provided on one side of the mounting frame 41, and a lifting rod 43 is installed inside the sleeve rod 42. A roller 44 is provided at the lower end of the lifting rod 43, and a pulley 45 is provided above the lifting rod 43. A rotating eccentric wheel 46 is provided on one side of the mounting frame 41 above the pulley 45. The smaller end of the rotating eccentric wheel 46 can rotate relative to the mounting frame 41. Furthermore, a rotating frame 47 with a Z-shaped design is provided at the larger end of the rotating eccentric wheel 46. Specifically, the mounting frame 41 is connected to the outer side of the grid-connected cabinet body 1, and the sleeve rod 42 is located on the inner side of the mounting frame 41. In other words, when the position of the grid-connected cabinet body 1 needs to be adjusted, force is applied to the rotating frame 47. When the rotating frame 47 rotates, the driving force acts on the rotating eccentric wheel 46, and the smaller end of the rotating eccentric wheel 46 rotates relative to the mounting frame 41. When the lifting rod 43 rotates, it acts on the pulley 45. Under the rotation of the eccentric wheel 46, the lifting rod 43 moves vertically relative to the sleeve rod 42, causing the roller 44 to move downward and protrude from the lower end face of the mounting bracket 41. This allows the grid-connected cabinet body 1 to be lifted vertically by a certain distance, facilitating contact between the roller 44 and the ground. Considering its practical functionality, a locking screw 352 can be set on the outside of the sleeve rod 42. That is, when the lifting moving mechanism 4 changes from the state of supporting the grid-connected cabinet body 1 with the mounting bracket 41 to the state of the grid-connected cabinet body 1 being movable and adjustable, the locking screw 352 is screwed on so that it passes through the sleeve and abuts against the mounting bracket 41, thereby locking the lifting moving mechanism 4 in the use state and improving its functionality. Of course, a corresponding screw hole can be opened in the mounting bracket 41 corresponding to the locking screw 352 to ensure the stability of the locking effect and provide a prerequisite for the subsequent movement and adjustment of the grid-connected cabinet body 1.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
