Two first vertical rods are provided on one side of the top surface of the base plate, and a sleeve is provided on one side of each first vertical rod. Two strip-shaped grooves are formed on the other side of the top surface of the base plate, and second vertical rods are provided within these grooves. A stop bar is provided on one side of each second vertical rod. The beneficial effects of this utility model are: by setting the first and second vertical rods and using the sleeve and stop bar in combination, this utility model can protect and restrict the building electrical equipment placed on the base plate, preventing the equipment from slipping off the base plate during transportation, thus avoiding damage to the equipment and preventing injury to transportation personnel, thereby improving the safety of transportation personnel.

[0004] However, the existing mobile support structure is relatively simple, and electrical equipment transported on the platform surface is prone to leakage. Equipment that is not sufficiently grounded cannot release electricity, making operators susceptible to electric shock when operating the equipment.

[0005] Therefore, it is necessary to redesign and modify the movable supports for building electrical equipment. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a movable support for building electrical equipment, which has the advantage of improving safety in use. It solves the problems of existing movable supports having a relatively simple structure, electrical equipment transported on the platform surface being prone to leakage, and equipment not sufficiently grounded being unable to release electricity, which makes operators prone to electric shock when operating the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a movable support for building electrical equipment, including a load-bearing plate;

[0008] Both sides of the bottom of the support plate are fixedly connected to connecting frames, and both sides of the bottom of the connecting frames are equipped with rollers. The inner side of the connecting frames is provided with a limit frame through an adjustment structure. The top of the limit frame passes through the support plate and extends to the top of the support plate. The support plate is set in a hollow shape. The surface of the limit frame is fixedly connected to a cable. The side of the cable away from the limit frame is electrically connected to a grounding connector. The bottom of the grounding connector can contact the ground.

[0009] As a preferred embodiment of this utility model, the adjusting structure includes a bidirectional screw rod movably connected to the inner side of the connecting frame via a bearing. Both sides of the surface of the bidirectional screw rod are threaded with threaded sleeves, and both sides of the threaded sleeves are fixedly connected with connecting rods. A crank is sleeved on the surface of the connecting rod, and a support plate is movably connected to the side of the crank rod away from the connecting rod via a pin. The top of the support plate is connected to the bottom of the limiting frame.

[0010] As a preferred embodiment of this utility model, the surface of the support plate is provided with an adjustment groove, and the bottom of the limiting frame is threadedly connected with a bolt located inside the adjustment groove, and the bolt and the adjustment groove are slidably connected.

[0011] As a preferred embodiment of this utility model, connecting blocks are fixedly connected to both sides of the bottom of the bearing plate, and a support leg is movably connected to the surface of the connecting block by a pin. The side of the support leg away from the connecting block is in contact with the ground.

[0012] As a preferred embodiment of this utility model, a force-bearing rod is fixedly connected to the surface of the support leg, the force-bearing rod extends to the outside of the crank on the side away from the support leg, and the connecting rod is located at the bottom of the force-bearing rod and is slidably connected to the force-bearing rod.

[0013] As a preferred embodiment of this utility model, a vertical plate is fixedly connected to the surface of the support leg, and the grounding connector is embedded in the surface of the vertical plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides an active grounding path for electrical equipment placed on a support plate by connecting the limiting frame with cables and grounding connectors, and ensuring that the grounding connectors can contact the ground. Any leakage current of the equipment can be safely released through the limiting frame, cables, grounding connectors, and the earth, effectively preventing the operator from being electrocuted.

[0016] 2. This utility model uses an adjustment structure composed of a bidirectional screw, a screw sleeve, a connecting rod, a crank, and a support plate. By rotating a bidirectional screw, the limit frames on both sides can be driven to rise and fall simultaneously and synchronously, making the operation simple and labor-saving.

[0017] 3. The design of the adjustment groove and bolts in this utility model allows for fine adjustment of the position of the limit frame relative to the support plate after the position of the support plate is determined, providing additional flexibility to adapt to equipment of different sizes or shapes.

[0018] 4. This utility model provides additional and more stable support points for the support by lowering the outriggers after the support is moved to the target position so that they contact the ground, which greatly improves the overall stability of the support and prevents the support from shaking or moving accidentally during use.

[0019] 5. This utility model establishes a mechanical linkage by slidingly connecting the force-bearing rod on the outrigger with the connecting rod in the adjustment structure. When the outrigger is lowered, the movement of the outrigger is transmitted to the connecting rod through the force-bearing rod. The movement of the connecting rod will drive the crank and the support plate to move, thereby automatically adjusting the height of the limit frame.

[0020] 6. This utility model ensures that when the outrigger is lowered and stably contacts the ground by embedding the grounding connector into the upright plate on the surface of the outrigger, the grounding connector will also maintain good and stable contact with the ground. This directly improves the reliability of the grounding circuit. Attached Figure Description

[0026] 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.

[0027] like Figures 1 to 4 As shown, the present invention provides a movable support for building electrical equipment, including a support plate 1;

[0028] A connecting frame 2 is fixedly connected to both sides of the bottom of the support plate 1. Rollers 3 are installed on both sides of the bottom of the connecting frame 2. A limit frame 4 is set on the inner side of the connecting frame 2 through the adjustment structure. The top of the limit frame 4 passes through the support plate 1 and extends to the top of the support plate 1. The support plate 1 is set to be hollow. A cable 5 is fixedly connected to the surface of the limit frame 4. A grounding connector 6 is electrically connected to the side of the cable 5 away from the limit frame 4. The bottom of the grounding connector 6 can contact the ground.

[0029] refer to Figure 2 The adjustment structure includes a bidirectional screw 7 that is movably connected to the inner side of the connecting frame 2 via a bearing. Both sides of the surface of the bidirectional screw 7 are threaded with a screw sleeve 8. Both sides of the screw sleeve 8 are fixedly connected with a connecting rod 9. A crank 10 is sleeved on the surface of the connecting rod 9. A support plate 11 is movably connected to the side of the crank 10 away from the connecting rod 9 via a pin. The top of the support plate 11 is connected to the bottom of the limiting frame 4.

[0030] As a technical optimization of this utility model, the adjustment structure composed of a bidirectional screw 7, a screw sleeve 8, a connecting rod 9, a crank 10 and a support plate 11 can simultaneously and synchronously drive the lifting and lowering of the limit frames 4 on both sides by rotating a bidirectional screw 7, which is simple and labor-saving.

[0031] refer to Figure 2 The surface of the support plate 11 is provided with an adjustment groove 12, and the bottom of the limit frame 4 is threadedly connected with a bolt 13 located inside the adjustment groove 12. The bolt 13 and the adjustment groove 12 are slidably connected.

[0032] As a technical optimization of this utility model, the design of the adjusting groove 12 and the bolt 13 allows for fine adjustment of the position of the limiting frame 4 relative to the support plate 11 after the position of the support plate 11 is determined, providing additional flexibility to adapt to equipment of different sizes or shapes.

[0033] refer to Figure 4 Both sides of the bottom of the bearing plate 1 are fixedly connected to the connecting blocks 14. The surface of the connecting blocks 14 is movably connected to the support legs 15 through the pins. The side of the support legs 15 away from the connecting blocks 14 is in contact with the ground.

[0034] As a technical optimization of this utility model, after the support is moved to the target position, the outrigger 15 is lowered to make it contact the ground, providing an additional and more stable support point for the support, which greatly improves the overall stability of the support and prevents the support from shaking or moving accidentally during use.

[0035] refer to Figure 4A force-bearing rod 16 is fixedly connected to the surface of the outrigger 15. The force-bearing rod 16 extends to the outside of the crank 10 from the side away from the outrigger 15. The connecting rod 9 is located at the bottom of the force-bearing rod 16 and is slidably connected to the force-bearing rod 16.

[0036] As a technical optimization of this utility model, a mechanical linkage is established by sliding the force rod 16 on the support leg 15 with the connecting rod 9 in the adjustment structure. When the support leg 15 is lowered, the movement of the support leg 15 is transmitted to the connecting rod 9 through the force rod 16. The movement of the connecting rod 9 will drive the crank 10 and the support plate 11 to move, thereby automatically adjusting the height of the limit frame 4.

[0037] refer to Figure 4 The support leg 15 is fixedly connected to the upright plate 17, and the grounding connector 6 is embedded in the surface of the upright plate 17.

[0038] As a technical optimization of this utility model, by embedding the grounding connector 6 into the upright plate 17 on the surface of the support leg 15, it is ensured that when the support leg 15 is lowered and stably contacts the ground, the grounding connector 6 will also maintain good and stable contact with the ground. This directly improves the reliability of the grounding circuit.

[0039] The working principle and usage process of this utility model are as follows: When the operator needs to transport and operate building electrical equipment, the mobile support is first easily moved by the rollers 3 at its bottom. The bearing plate 1 has a hollow design, which not only reduces weight but also facilitates heat dissipation and prevents water accumulation. After the support is moved to the target position, the operator begins the fixing and grounding process: by rotating the bidirectional screw 7 inside the connecting frame 2, the rotation of the screw drives the two threaded sleeves 8 on its surface to move towards each other. The movement of the threaded sleeves 8 is transmitted to the crank 10 through the connecting rod 9. The crank 10 moves with the pin as the fulcrum, thereby pushing the support plate 11 to adjust up and down. The limiting frame 4 at the top of the support plate 11 moves accordingly. The top of the support plate 1 extends to the top, effectively limiting and fixing the electrical equipment. At the same time, it allows the cable 5 on the top of the limit frame 4 to contact the equipment. During the movement of the screw sleeve 8, the connecting rod 9 on the surface of the screw sleeve 8 slides into contact with the force rod 16. The movement of the connecting rod 9 indirectly affects the position of the support leg 15 through the force rod 16, realizing the coordination between the adjustment of the limit frame 4 and the lowering of the support leg 15. The vertical plate 17 on the surface of the support leg 15 is inlaid with a grounding connector 6. When the support leg 15 is fully lowered, the grounding connector 6 automatically contacts the ground. The cable 5 on the surface of the limit frame 4 forms a grounding path, safely conducting any potential leakage current to the ground and completely eliminating the risk of electric shock to the operator.

[0040] In summary, this movable support for building electrical equipment provides an active grounding path for electrical equipment placed on the support plate 1 by connecting the limiting frame 4 with the cable 5 and the grounding connector 6, and ensuring that the grounding connector 6 can contact the ground. Any leakage current from the equipment can be safely released through the limiting frame 4, the cable 5, the grounding connector 6, and the earth, effectively preventing electric shock to the operator.
