[0002] Building electrical cabinet is a device used to centrally install, protect and control electrical equipment and circuits inside a building. It usually consists of an external metal box, internal electrical components and a power distribution system, which is used to distribute electricity, control circuits, and provide safety protection functions.

[0003] A large amount of heat is generated when the building electrical cabinet is in operation. If the heat is not dissipated in time, it will affect the electronic control components inside the electrical cabinet. Traditional building electrical cabinets have filter holes or filter screens installed on the sides. The filter screens or filter holes are used to ventilate and dissipate heat inside the electrical cabinet. When the filter screen is exposed to the outside for a long time, some dust screens will clog the filter screen, and the filter screen needs to be disassembled here. However, traditional filter screens are installed and connected with bolts. When disassembling or installing, manual use of corresponding tools is required, and then the tools are repeatedly tightened to achieve the purpose of disassembly and installation. Bolts will oxidize when exposed to the outside for a long time, increasing the workload of disassembly and installation. At the same time, some building electrical cabinets installed outdoors may be hit by gravel or falling objects, which may cause damage to the top of the electrical cabinet, and the electrical cabinet needs to be replaced.

The inner wall of the plug-in block 17 is slidably connected with a movable column 14, and the movable column 14 is slidably connected to the inner wall of the plug-in block 17. The outer wall of the moving column 14 is fixedly connected with an extrusion plate 16, and the movement of the extrusion plate 16 can guide the plug-in block 17 so that it can only move in the vertical direction. The inner wall of the extrusion plate 16 is elastically connected with the plug-in block 13 through a limit spring 15. There are two groups of plug-in blocks 13, and both are L-shaped. The inner wall of the cabinet 1 is detachably installed with a filter screen 3, and the cabinet 1 is ventilated through the slots of the filter screen 3. The bottom end of the filter screen 3 is fixedly connected with a moving block 10. There are two groups of moving blocks 10, and both are T-shaped, so that the filter screen 3 falls off the inner wall of the cabinet 1 when moving.

[0024] In the embodiment of the utility model, the building electrical cabinet with good ventilation effect, the top of the cabinet body 1 is slidably connected with a movable block 9, the movable block 9 is provided with four groups, and can only move horizontally, the outer wall of the movable block 9 is hinged with a movable plate 8, the movement trajectory of the movable plate 8 is an arc trajectory, the top of the movable plate 8 is hinged with a fixed block 7, the fixed block 7 is provided with four groups and can only move vertically, the top of the fixed block 7 is fixedly connected with a connecting plate 6, the outer wall of the connecting plate 6 is fixedly connected with an elastic telescopic rod 5, the elastic telescopic rod 5 is formed by two groups of sleeve rods being sleeved with each other, and relative sliding can occur between them to change its overall length, and the elastic telescopic rod 5 is built with a spring so that It has a certain elasticity, and the inner wall of the elastic telescopic rod 5 is filled with damping liquid, which plays a buffering role. The top of the connecting plate 6 is fixedly connected with a baffle 2, which prevents some gravel and falling objects from falling and causing damage to the top of the cabinet 1. One end of the connecting spring 12 is fixedly connected to the inner wall of the fixing seat 11, and the other end of the connecting spring 12 is fixedly connected to the top of the plug-in block 17. The outer wall of the plug-in block 17 is slidably connected to the inner wall of the fixing seat 11. When the plug-in block 17 is squeezed, it will move upward, squeezing the corresponding connecting spring 12 to shorten its length. When the plug-in block 17 is not squeezed, the elasticity of the connecting spring 12 will reset, and the limit spring One end of 15 is fixedly connected to the outer wall of the plug block 13, and the other end of the limit spring 15 is fixedly connected to the inner wall of the extrusion plate 16. The outer wall of the plug block 13 is slidably connected to the inner wall of the extrusion plate 16. When the plug block 13 is squeezed, it will move upward, squeezing the corresponding limit spring 15 to shorten its length. When the plug block 13 is not squeezed, the elasticity of the limit spring 15 will reset, and the outer wall of the plug block 13 will be plugged into the inner wall of the positioning plate 4. When the plug block 13 is plugged into the positioning plate 4, the plug block 17 is always in an upwardly expanded state, thereby releasing the limit of the plug block 17 and the filter screen 3. At this time, the staff can disassemble the filter screen 3, and the plug block 13 The outer wall contacts the outer wall of the positioning plate 4. When installing the filter screen 3, the top of the filter screen 3 squeezes the inclined surface of the plug-in block 17, so that the plug-in block 17 moves upward, which is convenient for installation. The bottom end of the plug-in block 17 is plugged into the inner wall of the top of the filter screen 3, and the traditional bolt installation is replaced by plug-in, so as to achieve the purpose of saving time and effort in disassembly and installation. The outer wall of the filter screen 3 and the movable block 10 are both slidably connected to the inner wall of the cabinet 1. After the limit of the plug-in block 17 is released, the filter screen 3 can be moved and then taken out, and then it can be cleaned. The bottom end of the elastic telescopic rod 5 is fixedly connected to the top of the cabinet 1, and the elastic telescopic rod 5 can guide the baffle 2.

[0025] In the utility model, when in use, when the cabinet 1 is placed outdoors for a long time, some dust will block the filter holes of the filter screen 3, making the overall ventilation effect of the cabinet 1 worse. At this time, the filter screen 3 needs to be disassembled, and then the filter screen 3 is cleaned, and the two groups of plug-in blocks 13 are moved to the middle by pressing the two groups of plug-in blocks 13, and then the plug-in block 17 can be moved upward through the squeezing plate 16. At this time, the plug-in limit of the plug-in block 17 and the filter screen 3 is released, and then the movable column 14 is pushed so that the movable column 14 drives the squeezing plate 16 and the two groups of plug-in blocks 13 to move, and then the two groups of plug-in blocks 13 are loosened. At this time, due to the elasticity of the limit spring 15, the two groups of plug-in blocks 13 are reset and the two groups of plug-in blocks 13 are plugged with the two groups of positioning plates 4, and then The relevant personnel can then remove the filter 3 and disassemble it for cleaning. The operation is simple and convenient, and it avoids repeatedly tightening the bolts to achieve the purpose of disassembling and installing the filter 3. At the same time, when some falling objects or gravel fall, the gravel or falling objects will first contact the baffle 2, causing the baffle 2 to move downward. In the process of the baffle 2 moving downward, the top sleeve of the elastic telescopic rod 5 will be driven to move downward, and the sleeve will squeeze the damping liquid on the inner wall of the elastic telescopic rod 5. The damping liquid will hinder the movement of the sleeve due to its own properties, thereby forming its motion damping, and the movable plates 8 at both ends will drive the two groups of movable blocks 9 to move toward both ends, unloading a part of the impact force of the falling objects and gravel, so that the device can reduce the impact force on the cabinet 1 by buffering and damping.
