Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically an adjustable power distribution cabinet. Background Technology

[0002] Power distribution cabinets (also known as distribution boxes or distribution cabinets) are important equipment used in power systems for distributing electricity. They are key components for power conversion in power systems, used to distribute electrical energy and control, protect, and monitor circuits. Distribution cabinets are commonly used in power distribution systems in industrial, commercial, and residential buildings to ensure a safe and efficient power supply to electrical equipment.

[0003] Chinese Patent Publication No. (CN211183030U) discloses a volume adjustable power distribution cabinet, including a cabinet with an opening on one side. Two ventilation windows are symmetrically fixedly installed on two side walls of the cabinet that are far apart from each other. Two guide rails are symmetrically fixedly installed inside the cabinet. Four suspension mechanisms are slidably installed on the two guide rails. The four suspension mechanisms are threadedly connected to the two guide rails by several symmetrically arranged second fastening screws. A support plate is engaged and installed on each of the two suspension mechanisms near the opening of the cabinet. Two hinges are symmetrically installed on one outer side wall of the cabinet. A door panel is rotatably installed on the side of the cabinet near the opening through the two hinges. A glass plate is fixedly installed on the door panel.

[0004] In the aforementioned comparative documents, to secure the suspension mechanism to the guide rail, a second fastening screw is typically inserted into a threaded hole on the slider and connected to the corresponding second threaded groove on the guide rail via a threaded connection. While this method ensures the stability of the suspension mechanism, its design has certain limitations. Because the number of second threaded grooves on the guide rail is fixed, and the distance between each second threaded groove is constant, the installation position of the suspension mechanism is also fixed. This means that if the user needs to adjust the height or position of the suspension mechanism, they will be limited by the layout of the second threaded grooves on the guide rail, resulting in insufficient flexibility and making it difficult to meet the needs of different application scenarios.

[0005] In view of this, the present invention solves the above-mentioned technical problems by proposing an adjustable power distribution cabinet. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an adjustable power distribution cabinet. When the mounting plate needs to be fixed, the user can press the first and second connecting rods to change them from a folded state to a parallel state, pushing the two connecting plates to move back to back. This causes the two compression blocks to compress and plastically deform, increasing the friction with the anti-slip texture on the sliding groove surface, thus fixing the mounting plate in any position. Simultaneously, as the first and second connecting rods become parallel, the bottom of the connection will compress the inclined surface of the locking block, causing it to contract. Then, under the action of the second return spring, the locking block extends again, limiting the first and second connecting rods and preventing the mounting plate from loosening when fixed. When the mounting plate needs to be loosened, simply pull the locking block manually to release the limitation. The compression block returns to its original shape under the action of the first return spring, causing the connecting plates to move relative to each other, folding the first and second connecting rods, and thus loosening the mounting plate. The entire process allows the mounting plate to freely adjust its position and height on the guide plate surface, greatly improving the flexibility and adaptability of the distribution cabinet in different application scenarios.

[0007] This utility model provides the following technical solution: an adjustable power distribution cabinet, including a cabinet body;

[0008] Guide plates are bolted to both sides of the inner cavity of the power distribution cabinet. A sliding groove is provided on one side of each of the two guide plates. A mounting plate is slidably connected to the surface of the guide plate. Two connecting plates are slidably connected to the inner cavity of the mounting plate. A pressing block is fixedly connected to one side of each of the two connecting plates. The pressing block is located in the inner cavity of the sliding groove. A first connecting rod and a second connecting rod are rotatably connected to the inner cavities of the two connecting plates respectively. The first connecting rod and the second connecting rod are connected by a pin. A pressing groove is provided at the top of the mounting plate. A first return spring is fixedly connected to the opposite surfaces of the two connecting plates and the mounting plate.

[0009] As a preferred embodiment of this utility model, the locking assembly includes two guide rods, which are fixed inside the mounting plate. Locking blocks are slidably connected to the surfaces of the two guide rods. A second return spring is fitted onto the surface of each guide rod, and a slope is formed on the rear surface of the locking block.

[0010] As a preferred technical solution of this utility model, heat dissipation holes are provided on both sides of the power distribution cabinet body, and a cooling fan is fixedly connected to the top of the power distribution cabinet body.

[0011] As a preferred embodiment of this utility model, the surface of the sliding groove is provided with anti-slip texture, the anti-slip texture is a diamond pattern, and the extrusion block is a rubber extrusion block.

[0012] As a preferred embodiment of this utility model, the bottom of the guide plate is bolted with a connecting block, the locking block is fixedly connected to the opposite side of the mounting plate with a bellows cover, and the bottom of the inner cavity of the mounting plate is fixedly connected with a limiting block, which is located below the first connecting rod and the second connecting rod.

[0013] As a preferred embodiment of this utility model, the sliding groove is T-shaped, the combination of the connecting plate and the extrusion block is T-shaped, and the width of the extrusion block is smaller than the width of the sliding groove.

[0014] As a preferred embodiment of this utility model, the pressing groove is rectangular in shape, and the width of the pressing groove is greater than the width of the first connecting rod and the second connecting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model overcomes the limitation of fixed threaded grooves by using a sliding groove to make the mounting plate slide and connect with the guide plate surface. This allows the mounting plate to be fixed at any position on the guide plate surface. This design improves the flexibility of installation and can meet the needs of adjusting the height and position of the mounting plate in different application scenarios.

[0017] 2. This utility model adopts a folding and unfolding mechanism of the first and second connecting rods, which, together with the anti-slip texture of the extrusion block and the sliding groove surface, generate a large friction force, thereby achieving stable fixation of the mounting plate. In addition, the design of the locking block further ensures the stability of the connection when the first and second connecting rods are in a parallel state, preventing the first and second connecting rods from folding after the mounting plate is fixed, thus improving the fixation stability of the mounting plate.

[0018] 3. This utility model allows for the fixing and loosening of the mounting plate by simply pressing the first and second connecting rods and pulling the locking block, simplifying the operation process and improving work efficiency. 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] Please see Figure 1-6As shown, the adjustable power distribution cabinet includes a cabinet body 1. Guide plates 2 are bolted to both sides of the inner cavity of the cabinet body 1. A sliding groove 201 is provided on one side of each guide plate 2. A mounting plate 202 is slidably connected to the surface of the guide plate 2. Two connecting plates 203 are slidably connected to the inner cavity of the mounting plate 202. A pressing block 204 is fixedly connected to one side of each connecting plate 203. The pressing block 204 is located within the inner cavity of the sliding groove 201. A first connecting rod 205 and a second connecting rod 206 are rotatably connected to the inner cavities of the two connecting plates 203, respectively. The first connecting rod 205 and the second connecting rod 206 are connected by a pin. A pressing groove 207 is provided at the top of the mounting plate 202. The opposing surfaces of the two connecting plates 203 and the mounting plate 202 are fixedly connected. A first return spring 208 is fixedly connected to the mounting plate 202. A locking assembly is fixedly connected inside the mounting plate 202. The locking assembly includes two guide rods 3. The two guide rods 3 are mainly used to guide and limit the locking block 301. The two guide rods 3 are fixed inside the mounting plate 202. The locking block 301 is slidably connected to the surface of the two guide rods 3. A second return spring 302 is fitted on the surface of the guide rods 3. An inclined surface 303 is opened on the rear surface of the locking block 301. Heat dissipation holes 4 are opened on both sides of the power distribution cabinet body 1. A cooling fan 401 is fixedly connected to the top of the power distribution cabinet body 1. The heat dissipation holes 4 and the cooling fan 401 are mainly used to cool the power distribution cabinet body 1. The electronic components inside the cavity are cooled. The surface of the sliding groove 201 has anti-slip textures to increase the friction between the sliding groove 201 and the extrusion block 204, ensuring the stability of the mounting plate 202 when fixed. The anti-slip textures are diamond-shaped to further enhance friction. The extrusion block 204 is a rubber extrusion block, made of rubber material, possessing a certain degree of elasticity and plastic deformation capability. A connecting block 5 is bolted to the bottom of the guide plate 2. By setting and removing the connecting block 5, the mounting plate 202 can be added or removed. A bellows cover 501 is fixedly connected to the opposite side of the locking block 301 and the mounting plate 202. The bellows cover 501 is mainly used to prevent foreign objects from entering the mounting plate 202. The inner cavity of 02 affects the reset of the locking block 301. Simultaneously, the bellows cover 501 can retract or expand according to the movement of the locking block 301. A limit block 502 is fixedly connected to the bottom of the inner cavity of the mounting plate 202. The limit block 502 is mainly used to prevent the first connecting rod 205 and the second connecting rod 206 from folding downwards after they are parallel. The limit block 502 is located below the first connecting rod 205 and the second connecting rod 206. The sliding groove 201 is T-shaped, and the combined shape of the connecting plate 203 and the pressing block 204 is T-shaped. The width of the pressing block 204 is smaller than the width of the sliding groove 201, creating a certain gap between the pressing block 204 and the sliding groove 201. This allows the connecting plate 203 to move the pressing block 204.The pressing block 204 can move away from and no longer contact the anti-slip texture of the sliding groove 201 through the gap. The pressing groove 207 is rectangular in shape, and the width of the pressing groove 207 is greater than the width of the first connecting rod 205 and the second connecting rod 206, so that the first connecting rod 205 and the second connecting rod 206 can be folded upward through the width of the pressing groove 207. If the width of the pressing groove 207 is less than the width of the first connecting rod 205 and the second connecting rod 206, it will affect the upward folding of the first connecting rod 205 and the second connecting rod 206.

[0028] Since the first link 205 and the second link 206 are initially folded upwards, when it is necessary to fix the mounting plate 202, the user uses their fingers to press down on the connection between the first link 205 and the second link 206 through the pressing groove 207, so that the originally folded first link 205 and the second link 206 gradually become parallel. During this process, the first link 205 and the second link 206 push the connecting plate 203 to move in opposite directions. The opposite movement of the connecting plate 203 drives the pressing block 204 to move in opposite directions and compresses the first return spring 208. Since the pressing block 204 is made of rubber, it will undergo plastic deformation when it comes into contact with the anti-slip texture on the surface of the sliding groove 201, thereby generating a large frictional force, so that the mounting plate 202 moves in any direction on the guide plate 2. With the position fixed, as the first link 205 and the second link 206 gradually become parallel, the bottom of the connection between the first link 205 and the second link 206 will contact the inclined surface 303 of the locking block 301, causing the locking block 301 to retract. When the first link 205 and the second link 206 become completely parallel, the locking block 301 extends under the action of the second return spring 302, limiting the connection between the first link 205 and the second link 206 to prevent the connection between the first link 205 and the second link 206 from folding upward when the mounting plate 202 is fixed, causing the compression block 204 to retract. At the same time, the limiting block 502 located below the first link 205 and the second link 206 can prevent the connection between the first link 205 and the second link 206 from folding downward.

[0029] When it is necessary to loosen the mounting plate 202, first pull the locking block 301 so that the locking block 301 no longer limits the connection between the first link 205 and the second link 206. Since the pressing block 204 and the first return spring 208 are compressed, the pressing block 204 and the first return spring 208 will return to their original shape, so that the pressing block 204 no longer contacts the anti-slip texture of the sliding groove 201, and drives the connecting plate 203 to move relative to each other, and causes the first link 205 and the second link 206 to fold upward, thereby loosening the mounting plate 202.
