[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a modularly assembled high and low voltage complete set of equipment, including an equipment cabinet 1. The bottom of the equipment cabinet 1 is fixedly connected with casters 2. The casters 2 can be casters with self-locking function. The equipment cabinet 1 can be moved by the casters 2 to improve the flexibility of the equipment cabinet 1. Assembly mechanisms 3 are provided on the left and right sides of the equipment cabinet 1, and stabilizing mechanisms 4 are provided at the bottom of the equipment cabinet 1.

[0020] Reference Figures 1-3The assembly mechanism 3 includes a boss 31, which is fixedly connected to the right end of the equipment cabinet 1. A retaining frame 32 is fixedly connected to the left side of the equipment cabinet 1. The end of the boss 31 away from the equipment cabinet 1 has an inclined surface 33. A groove 34 is formed on the inner wall of the boss 31. When the roller 37 is inserted into the groove 34, it can limit the retaining frame 32 to the outer wall of the boss 31. A pull rod 35 is slidably connected through the inner wall of the retaining frame 32. The pull rod 35 is a rod-shaped structure with the top of the pull rod 35 extending above the retaining frame 32. Pulling the pull rod 35 upwards... 5 can drive the roller 37 to move out of the inside of the groove 34, thereby separating the assembled equipment cabinet 1. The bottom of the pull rod 35 is fixedly connected to the limit spring 36. The end of the limit spring 36 away from the pull rod 35 is fixedly connected to the inner wall of the frame 32. The inner wall of the pull rod 35 is rotatably connected to the roller 37. When the frame 32 is docked with the boss 31, the roller 37 inside it contacts the inclined surface 33. The roller 37 will be squeezed by the inclined surface 33, causing the roller 37 to roll against the surface of the inclined surface 33 and push the pull rod 35 upward.

[0021] Reference Figures 1-3 The stabilizing mechanism 4 includes a slide rod 41, which is slidably connected to the inner wall of the boss 31. A suction cup 42 is fixedly connected to the bottom of the slide rod 41. By sliding the slide rod 41 downward, the suction cup 42 at its bottom can be attracted to the surface of the workshop floor. The slide rod 41 has an "L" shaped structure. There are three sets of suction cups 42, which are equidistantly arranged at the bottom of the slide rod 41 in the horizontal direction. When the three sets of suction cups 42 are attracted to the workshop floor, the stability of the equipment cabinet 1 during use can be improved. A positioning rod 44 is fixedly connected to the top of the slide rod 41. The positioning rod 44 is slidably connected to the inner wall of the boss 31. A return spring 45 is fixedly connected to the end of the positioning rod 44 away from the slide rod 41. The end of the return spring 45 away from the positioning rod 44 is fixedly connected to the inner wall of the boss 31. Through the elasticity of the return spring 45 and the positioning rod 44, the slide rod 41 can be moved to slide downward and reset on the inner wall of the boss 31.

[0022] Reference Figures 1-3 The outer wall of the boss 31 is slidably connected to the limiting frame 46. The side wall of the slide rod 41 is provided with a limiting groove 43 that matches the limiting frame 46. When the frame 32 pushes the limiting frame 46, the limiting frame 46 will move out of the limiting groove 43. When the limiting frame 46 moves out of the limiting groove 43, the limiting of the slide rod 41 will be released.

[0023] Working principle: When assembling two sets of equipment cabinets 1, the left side frame 32 of one set of equipment cabinets 1 is aligned with the right side boss 31 of the other set of equipment cabinets 1 and a pushing force is applied. Simultaneously, the casters 2 facilitate smooth movement of the equipment cabinets 1, causing the left side frame 32 of one set of equipment cabinets 1 to gradually fit onto the outer wall of the right side boss 31 of the other set of equipment cabinets 1. At the same time, during the docking process between the frame 32 and the boss 31, when the roller 37 inside the frame 32 contacts the inclined surface 33, the roller 37 is squeezed by the inclined surface 33, causing it to roll against the surface of the inclined surface 33 and push the pull rod 35 upwards. This allows the pull rod 35 to move smoothly within the frame 32. The inner wall slides upward and stretches the limiting spring 36. As the equipment cabinet 1 moves, the roller 37 inside the frame 32 will move against the surface of the inclined plane 33 and gradually approach the groove 34. When the roller 37 and the groove 34 are completely overlapped, the roller 37 will be released from the pressure of the inclined plane 33. At this time, under the elastic action of the limiting spring 36, the pull rod 35 can be driven to slide down and reset on the inner wall of the frame 32. During the downward sliding and reset process, the pull rod 35 will drive the roller 37 to insert into the inside of the groove 34. At this time, the frame 32 can be limited to the outside of the boss 31 by the roller 37 cooperating with the groove 34, thus completing the assembly of the two sets of equipment cabinets 1.

[0024] When it is necessary to separate the assembled equipment cabinet 1, simply pull the lever 35 upward to move the roller 37 out of the groove 34, thereby releasing the roller 37 from the limit of the frame 32. Then push the equipment cabinet 1 to separate the frame 32 from the boss 31, thus completing the separation of the two sets of equipment cabinet 1.

[0025] As the card frame 32 gradually fits onto the outer wall of the boss 31, it contacts the limiting frame 46, which pushes the limiting frame 46, causing it to slide on the outer wall of the boss 31 and gradually approach the equipment cabinet 1. At the same time, the limiting frame 46 gradually moves out of the limiting groove 43. When the limiting frame 46 is completely removed from the limiting groove 43, it releases the limiting of the slide rod 41. At this time, under the elastic action of the return spring 45, the positioning rod 44 can slide down and reset on the inner wall of the boss 31. Simultaneously, the positioning rod 44 will drive the slide rod 41 to slide down synchronously on the inner wall of the boss 31. The downward sliding of the slide rod 41 can cause the suction cup 42 at its bottom to adhere to the surface of the workshop floor. The adhesion of the suction cup 42 to the workshop floor can improve the stability of the equipment cabinet 1 during use, thereby improving the stability of the modularly assembled equipment cabinet 1.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
