Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a distribution box with an extended structure. Background Technology

[0002] A distribution box contains a vast amount of data parameters. It typically forms a low-voltage electrical wiring system, requiring the assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment within a closed or semi-closed metal cabinet or panel. During normal operation, circuits can be connected or disconnected manually or automatically. Distribution boxes are characterized by their small size, easy installation, specialized technical performance, fixed location, unique configuration functions, lack of site restrictions, widespread application, stable and reliable operation, high space utilization, small footprint, and environmental benefits. During application, numerous devices are installed inside the distribution box for power supply or protection. The dimensions of the distribution box are generally fixed.

[0003] For example, the prior art Chinese patent publication number "CN222463884U" provides a distribution box with an extended structure, including a distribution box body, extension boxes on both sides of the distribution box body, a reinforcing rod installed inside the distribution box body near the back end, grooves opened on the inner walls of both sides of the distribution box body, bolts connecting the front and rear ends of the distribution box body, a dustproof net connected to the outer wall of the extension box, a dustproof net shielding component provided on the outer wall of the extension box, and a base connected to the bottom end of the distribution box body.

[0004] This device can be adjusted when the internal space of the distribution box is insufficient during use, thereby increasing the internal space to facilitate the installation of more equipment. At the same time, when used outdoors, it can also increase the sealing of the distribution box in case of rain, preventing rainwater from entering and causing damage to the equipment, thus improving the practicality of the distribution box.

[0005] Existing distribution boxes with extendable structures expand the internal space when components cannot be installed. However, the expanded space lacks connecting structures, making it inconvenient to install components. Furthermore, the fixed installation space is unsuitable for components of different sizes, hindering adjustments to the installation space. Additionally, when used indoors, the bottom of the distribution box is easily exposed to moisture, causing corrosion of the extendable structure, affecting its extension and the safe use of components.

[0006] Therefore, a distribution box with an extended structure is proposed. Utility Model Content

[0007] The purpose of this utility model is to solve the shortcomings of existing technologies where, after the extension structure expands the internal space of the distribution box, the expanded space lacks a connecting structure, making it inconvenient to install connecting structures for components. Furthermore, when the fixed installation space is unsuitable for components of different sizes, it is inconvenient to adjust the size of the installation space for the components. Therefore, this utility model proposes a distribution box with an extension structure.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] Design a distribution box with an extended structure, including a box body, a bottom plate fixed to the bottom end of the box body, a door installed on the front of the box body, a handle fixed to the surface of the door, a support plate installed inside the bottom end of the box body, support columns fixed at the four corners of the top of the support plate, a first mounting plate installed between two support columns, a lifting column inserted into the top of the support column, a top plate fixed to the top of the lifting column, an outer shell fixed to the bottom end of the top plate and located outside the box body, and an inner shell fixed to the bottom end of the top plate and located inside the box body.

[0010] Furthermore, a humidity sensor is installed at the top of the base plate, and a first electric push rod is fixed in the middle of the top of the base plate. The first electric push rod is vertically arranged, and its top is fixedly connected to the middle of the bottom of the support plate. The support plate is a rectangular plate structure and is horizontally slidably installed inside the box.

[0011] Furthermore, the inner surface of the box body has a guide groove, and the middle of the side of the support plate is guided up and down by a fixing block inserted into the guide groove. The support column is a rectangular column structure and is set vertically. It has a lifting groove inside, and the bottom end of the lifting column is slidably inserted into the lifting groove.

[0012] Furthermore, the lifting groove has a connecting groove on its side, and the first mounting plate has a first connecting post fixed at both ends. The first connecting post is slidably inserted into the connecting groove. The first connecting post has a threaded post structure, and a first nut is connected to its surface. The first nut is pressed against the side of the support post. The surface of the first mounting plate has a first mounting hole evenly distributed.

[0013] Furthermore, a second electric push rod is installed at the bottom of the lifting trough, and the top of the second electric push rod is fixedly connected to the bottom of the lifting column. The side of the lifting column has an overlapping groove, which is a C-shaped structure and is horizontally arranged.

[0014] Furthermore, a second mounting plate is installed between the two lifting columns. The surface of the second mounting plate is evenly provided with second mounting holes. Second connecting columns are fixed at both ends of the second mounting plate. The second connecting columns are threaded columns and are slidably overlapped inside the overlap groove. A second nut is connected to the surface of the second connecting column and is fastened against the side of the lifting column.

[0015] Furthermore, both the outer shell and the inner shell have C-shaped cross-sections and are vertically arranged. The top plate is horizontally arranged, and a shield is connected to the front of its bottom end. The shield is an elastically adjustable shield structure and is vertically arranged.

[0016] Furthermore, a hanging rod is connected to the bottom end of the shield, and a limiting plate is fixed at the middle of the bottom end of the hanging rod and at the position on both sides of the handle. The surface of the limiting plate has a positioning hole, which is a threaded hole structure, and a positioning bolt is rotatably installed inside the thread. The positioning bolt passes horizontally through the inside of the handle.

[0017] The present invention provides a distribution box with an extended structure, which has the following advantages:

[0018] 1. This utility model installs a humidity sensor at the bottom of the box, which is connected to an external controller to detect the humidity at the bottom of the box. When the box is wet, the first electric push rod drives the support plate to move upward along the guide groove, thereby moving the first mounting plate and the second mounting plate upward, so that the extension structure is removed from the wet area, maintaining the flexible lifting and lowering of the extension structure and protecting the safety of the internal components of the distribution box.

[0019] 2. In this utility model, a first mounting plate is installed at the top of the support plate via a support column and a connecting groove. The spacing between adjacent first mounting plates can be adjusted along the connecting groove to facilitate the installation of components of different sizes. Furthermore, a lifting column is fixed at the bottom of the top plate. The lifting column slides into the lifting groove inside the support column and is adjusted for height by a second electric push rod. The second electric push rod is controlled by an external controller, which drives the lifting column to move up and down, thereby expanding the size of the internal space of the distribution box. Moreover, components can be installed at different heights by using overlapping grooves of different heights to install second mounting plates at different heights, allowing for flexible installation of components of different sizes.

[0020] 3. In this utility model, the inner shell and outer shell are fixed at the bottom of the top plate, and a shield is installed on the front side of the bottom of the top plate. In this way, after the space inside the distribution box is extended, the outer shell and inner shell can be stably extended and adjusted, and the position above the front end of the outer shell can be shielded by stretching the shield. The bottom end of the shield is positioned and connected to the handle by a limiting plate and a positioning bolt. Therefore, the shield is kept stable and shields the front end of the extended space, avoiding exposure of the extended space. Attached Figure Description
