Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a power engineering distribution box. Background Technology

[0002] Distribution boxes are frequently used in power engineering construction. Existing distribution boxes, widely used in industry, commerce, construction, and infrastructure, serve as the "nerve center" of the power network, ensuring the stable operation of the power system. They typically contain multiple racks for installing electrical components. However, a current type of power engineering distribution box (Announcement No.: CN220086753U) has the following disadvantages in use:

[0003] During use, the partitions inside the distribution cabinet can move up and down under the adjustment of the screw sleeve. However, when the first screw rotates, it will drive all the partitions to adjust. Since all the partitions are adjusted together, the space distribution at the top and bottom of the distribution box will be uneven. The top and bottom areas will waste space or have improper installation of electrical components due to the excessive or insufficient spacing between the partitions. Furthermore, it is not convenient to add or remove partitions as needed, and the practicality is relatively low. Therefore, this patent proposes a power engineering distribution box to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a power distribution box for power engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power distribution box for power engineering, including a distribution cabinet, with two fixed rods installed inside the distribution cabinet. A connecting groove is provided on the side of the two fixed rods that are close to each other. Multiple limiting blocks are installed in the connecting grooves. A connecting rod is inserted into the connecting groove. An installation groove is provided in the connecting rod. Sliding grooves are provided on both sides of the installation groove. A movable plate is slidably connected in the installation groove. Two fixed blocks are fixed to one end of the movable plate. A movable block is slidably connected in the sliding groove and contacts the fixed blocks. A movable rod is fixed on the side of the movable blocks that are far apart from each other. Limiting grooves are provided on both sides of the connecting rod. Inserted blocks are slidably connected in the limiting grooves. The movable rod passes through the connecting rod and is fixed to the inserted blocks. The inserted blocks are inserted between the two limiting blocks. A first spring is fixed between the movable plate and the installation groove. A second spring is fixed between the movable block and the sliding groove. A pull rod is fixed to the other end of the movable plate. A handle is fixed to the end of the pull rod located outside the connecting rod.

[0006] Furthermore, a mounting plate is fixed to the top of the connecting rod, and the mounting plate has multiple mounting holes.

[0007] Furthermore, the power distribution cabinet has an air inlet on one side and an air outlet on the other side.

[0008] Furthermore, protective covers are fixed on both sides of the power distribution cabinet. Multiple ventilation holes are opened on the side of the protective covers that are far apart from each other. An air intake fan is installed in the protective cover on the side of the air inlet, and an air supply fan is installed in the protective cover on the side of the air outlet.

[0009] Furthermore, the front of the distribution cabinet is equipped with a door.

[0010] Furthermore, the bottom of the power distribution cabinet is equipped with casters.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By creating a connecting groove in the fixed rod (inverted L-shape), the connecting rod can be moved out of the groove when it needs to be added or removed. Pulling the handle outward moves the lever outward, compressing the first spring and causing the moving plate and fixed block to move outward. This stretches the second spring, moving the moving block into the mounting groove, which in turn moves the moving rod and the insert block. The insert block then enters the limiting groove, facilitating adjustment of the connecting rod's position. Once the desired position is reached, releasing the handle allows the insert block to be inserted between the two corresponding limiting blocks for positioning and fixation. This allows for easy adjustment of the connecting rod's position according to the size of the electrical components in the distribution cabinet, making it highly practical.

Detailed Implementation

[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] Distribution boxes are frequently used in power engineering construction. Distribution cabinets are widely used in industry, commerce, construction, and infrastructure, serving as the "nerve center" of the power network and ensuring the stable operation of the power system. Existing distribution boxes typically have multiple racks for mounting electrical components. This invention provides a power engineering distribution box with a connecting groove 5 on the fixed rod 4. The connecting groove 5 is inverted L-shaped, allowing the rod to be moved out of the groove 5 when adding or removing connecting rods 7. This can be achieved by pulling the handle outwards. 17. The handle 17 drives the pull rod 11 to move outward, thereby compressing the first spring 12. The moving plate 9 and the fixed block 10 move outward, so that the second spring 16 stretches and drives the moving block 13 to move into the mounting groove 8, thereby driving the moving rod 14 and the insertion block 15 to move, so that the insertion block 15 enters the limiting groove, which facilitates the adjustment of the position of the connecting rod 7. When the appropriate position is reached, the handle 17 is released, and the insertion block 15 can be inserted between the two corresponding limiting blocks 6 to achieve limiting and fixing. It is convenient to adjust the position of the connecting rod 7 according to the size of the electrical components in the distribution cabinet 1, which is highly practical.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a power distribution box for electrical engineering, including a distribution cabinet 1. Two fixed rods 4 are installed inside the distribution cabinet 1. A connecting groove 5 is provided on one side of each fixed rod 4 that is close to each other. Multiple limiting blocks 6 are installed in the connecting groove 5. A connecting rod 7 is inserted into the connecting groove 5. An installation groove 8 is provided in the connecting rod 7. Sliding grooves are provided on both sides of the installation groove 8. A movable plate 9 is slidably connected in the installation groove 8. Two fixed blocks 10 are fixed to one end of the movable plate 9. A movable block 13 is slidably connected in the sliding groove. 3. The movable blocks 13 are in contact with the fixed block 10. The movable blocks 13 are fixed with movable rods 14 on the opposite sides. Limiting grooves are opened on both sides of the connecting rod 7. Insert blocks 15 are slidably connected in the limiting grooves. The movable rod 14 passes through the connecting rod 7 and is fixed to the insert blocks 15. The insert blocks 15 are inserted between the two limiting blocks 6. A first spring 12 is fixed between the movable plate 9 and the mounting groove 8. A second spring 16 is fixed between the movable block 13 and the sliding groove. A pull rod 11 is fixed at the other end of the movable plate 9. A handle 17 is fixed at the end of the pull rod 11 located outside the connecting rod 7.

[0021] It should be noted that by opening a connecting groove 5 on the fixed rod 4, the connecting groove 5 is inverted L-shaped. This allows the connecting rod 7 to be moved out of the connecting groove 5 when it is necessary to add or remove it. By pulling the handle 17 outward, the handle 17 moves the pull rod 11 outward, thereby compressing the first spring 12. The moving plate 9 and the fixed block 10 move outward, and the second spring 16 stretches, moving the moving block 13 into the mounting groove 8. This moves the moving rod 14 and the insertion block 15, allowing the insertion block 15 to enter the limiting groove. This facilitates the adjustment of the position of the connecting rod 7. Once the appropriate position is reached, the handle 17 is released, allowing the insertion block 15 to be inserted between the two corresponding limiting blocks 6 for limiting and fixing. This makes it easy to adjust the position of the connecting rod 7 according to the size of the electrical components in the distribution cabinet 1, which is highly practical.

[0022] like Figure 2 As shown, a mounting plate 18 is fixed to the top of the connecting rod 7, and multiple mounting holes are provided on the mounting plate 18. An air inlet is provided on one side of the distribution cabinet 1, and an air outlet is provided on the other side. Protective covers 3 are fixed to both sides of the distribution cabinet 1. Multiple ventilation holes are provided on the sides of the protective covers 3 that are far apart from each other. An intake fan is installed inside the protective cover 3 on the side with the air inlet, and a blower 19 is installed inside the protective cover 3 on the side with the air outlet. A door 2 is installed on the front of the distribution cabinet 1. Casters with anti-braking function are installed at the bottom of the distribution cabinet 1 to facilitate fixing the distribution cabinet 1 in a designated position.

[0023] It should be noted that the electrical equipment in the distribution cabinet 1 will generate heat during operation. Fresh air is introduced by installing an intake fan, and the exhaust fan 19 exhausts the hot air in the distribution cabinet 1, which effectively reduces the temperature inside the distribution cabinet 1, helps to provide air circulation and heat dissipation, maintains a stable temperature inside the distribution cabinet 1, extends the service life of the electrical equipment, and improves its reliability and safety.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
