Description
Technical Field
[0001] The utility model belongs to the technical field of distribution cabinets, and more specifically, particularly relates to a sealing structure of a distribution cabinet. Background Art
[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), and are the final equipment of the power distribution system. Distribution cabinets are the general term for motor control centers. Distribution cabinets are used in occasions where the load is relatively dispersed and the number of circuits is small; motor control centers are used in occasions where the load is concentrated and the number of circuits is large. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby loads. This level of equipment should provide protection, monitoring, and control for the load.
[0003] Based on the above, the inventor found the following problems: Most of the current distribution cabinets open from the middle to both sides. This way will have more gaps at the opening and closing doors, resulting in poor sealing at the opening and closing doors. During long-term use, moisture enters the interior of the distribution cabinet from the gaps of the opening and closing doors, which may affect the operation of the equipment inside the distribution cabinet.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sealing structure of a distribution cabinet is provided, in order to achieve a more practical and valuable purpose. Summary of the Utility Model
[0005] In order to solve the above technical problems, the utility model provides a sealing structure of a distribution cabinet to solve the problem that there are more gaps at the current opening and closing doors, resulting in poor sealing at the opening and closing doors.
[0006] The purpose and effect of the sealing structure of a distribution cabinet of the utility model are achieved by the following specific technical means:
[0007] A sealing structure of a distribution cabinet includes a cabinet body and an opening and closing door. A fixing plate is connected to the opening and closing door through fixing bolts. A moving groove is opened at the lower part of the opening and closing door. A pushing mechanism is arranged inside the moving groove. The pushing mechanism includes a moving part. An installation groove is installed at the lower part of the moving part. A plugging part is installed inside the installation groove. A plugging groove is opened inside the plugging part. A pushing rod is plugged inside the plugging groove. One end of the pushing rod is movably connected to a pulling rod through a first connecting shaft. One end of the pulling rod is connected to a pushing rod through a second connecting shaft. One end of the pushing rod is connected to a connecting rod through an installation shaft. One end of the connecting rod is connected to a sealing gasket.
[0008] Further, the number of the sealing gaskets is two. The two sealing gaskets are arranged oppositely and are attached to both sides inside the cabinet body. The number of the moving parts is two.
[0009] Furthermore, there is a space between the fixed plate and the opening and closing door. A limit block is installed on the inner side of the fixed plate, and a limit groove is opened on the limit block. The connecting rod is located inside the limit groove.
[0010] Furthermore, the two moving parts are connected by a connecting block. A through groove is opened on the fixed plate, and fixed blocks are installed on the upper and lower parts of the fixed plate where the through groove is located.
[0011] Furthermore, a rotating rod is rotatably installed on the inner side of the fixed block. A thread is opened in the middle of the rotating rod. An extension block is installed on the connecting block, and the rotating rod is connected to the extension block through the thread.
[0012] Furthermore, limit rods are installed on both sides of the cabinet body. A lifting block is slidably connected to the limit rods. An extension plate is installed on the lifting block, and the lifting block is connected to the fixed plate through the extension plate.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] In the utility model, when the moving part moves upward, it can drive the push rod to move through the lower plug-in part. The other end of the push rod presses down the pull rod through the first connecting shaft. The pull rod drives the push rod to move through the second connecting shaft. When the push rod moves, it can push the connecting rod to move. The connecting rod moves inside the limit groove. At the same time, the connecting rod can push one end of the sealing pad to move to both sides, so that the sealing pad fits to the connection between the inner side of the cabinet body and the opening and closing door, which can improve the overall sealing performance.
