Description

Technical Field

[0001] The invention relates to the technical field of distribution boxes, and in particular to a high-safety distribution box for buildings. Background Art

[0002] The building distribution box plays a vital role in the building electrical system. It is not only responsible for receiving electrical energy from the power supply, but also responsible for distributing it to various electrical equipment in the building. The existing building distribution box distributes the electrical energy to various electrical equipment after connecting the power cables to the internal electronic components through the wiring trough on the lower side of the box. However, after the cables pass through the wiring trough, there is a certain gap between the cables and the wiring trough, resulting in poor stability of the cable connection, which is easy to affect the power consumption of the equipment, and some animals (such as mice, etc.) can easily enter the box from the wiring trough and damage the electronic components in the box.

[0003] Therefore, a high-security distribution box for buildings has been developed that can compress and fix the cables while closing the box door, thereby improving the stability of the cable connection and blocking the cable access groove to prevent animals such as rats from entering the box. Summary of the invention

[0004] In order to overcome the shortcomings of existing building distribution boxes, in which a certain gap is left between the cables and the wiring troughs, resulting in poor stability of the cable connection, which is easy to affect the power consumption of equipment, and some animals (such as mice, etc.) can easily enter the box through the wiring troughs and damage the electronic components in the box. The present invention provides a high-safety distribution box for buildings that can compress and fix the cables while closing the box door, thereby improving the stability of the cable connection and blocking the cable access troughs to prevent animals such as mice from entering the box.

When the box door is rotated and closed, the extrusion piece will be driven to move to the front side of the pushing rod and squeeze the pushing rod to move backward. The first spring is squeezed and contracted, and then the pushing rod pushes the upper part of the second connecting piece to swing backward, thereby causing the rotating seat to rotate, driving the cable management plate to rotate, so that the cable management plate presses the cables onto the mounting frame. When the box door is opened, the extrusion piece disengages from the pushing rod, and the first spring rebounds, causing the pushing rod to reset, and the rotating seat is reset by gravity, so that the cable management plate no longer presses the cables, thereby facilitating maintenance.

After the ejection piece is separated from the third connecting piece, it rebounds through the second spring, so that the mounting plate is reset.

[0012] Furthermore, it also includes an air supply mechanism, which includes a fixed frame, a filter and a fan. The left and right parts of the mounting frame are connected to the fixed frame, and the filter is clamped on the fixed frame.

The desiccant is placed in the placement rack. When the humidity in the installation rack is high, the desiccant absorbs moisture.

[0015] Beneficial effects of the present invention: 1. In the present invention, when the box door is closed, the extrusion member squeezes the push rod, causing the push rod to move backward on the guide seat, and then the push rod pushes the second connecting member to move backward, causing the rotating seat to rotate, driving the cable management plate to rotate and press the cables onto the mounting frame, thereby achieving the effect of pressing and fixing the cables while closing the box door, improving the stability of the cable connection, and at the same time blocking the cable access groove to prevent animals such as mice from entering the box.

DETAILED DESCRIPTION

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] A high-security distribution box for buildings, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, a first connecting member 0, a front frame 2, a top cover 3, a box door 4, a back plate 5 and a blocking mechanism 6. The left and right sides of the mounting frame 1 are connected to two front and rear first connecting members 0. The left and right sides of the mounting frame 1 are provided with ventilation slots for ventilation and heat dissipation. The front side of the mounting frame 1 is connected to the front frame 2, and the upper side of the mounting frame 1 is connected to the top cover 3. The top cover 3 is a trapezoidal structure for dust prevention and cleaning. The front side of the right part of the front frame 2 is rotatably connected to the box door 4, and the rear side of the mounting frame 1 is connected to the back plate 5. A blocking mechanism 6 is provided between the mounting frame 1 and the box door 4.

[0039] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the blocking mechanism 6 includes a rotating seat 60, a wire management plate 61, a second connecting member 62, a guide seat 63, a pushing rod 64, a first spring 65 and an extrusion member 66. The rotating seat 60 is rotatably connected to the lower side of the mounting frame 1, and the wire management plate 61 is connected to the front of the rotating seat 60. A rubber sheet is provided on the wire management plate 61 to facilitate pressing the cables. The second connecting member 62 is connected to the left side of the rotating seat 60, and the guide seat 63 is connected to the inner side of the lower left part of the mounting frame 1. A pushing rod 64 is slidably connected to the guide seat 63. The pushing rod 64 is extruded and matched with the second connecting member 62, and the pushing rod 64 passes through the front frame 2. A first spring 65 is connected between the pushing rod 64 and the guide seat 63. An extrusion member 66 is connected to the lower left side of the box door 4. When the box door 4 is rotated and closed, the extrusion member 66 will be driven to move to the front side of the pushing rod 64 and squeeze the pushing rod 64 to move backward.

[0040] When using the present invention, first place the mounting frame 1 in the use area, the top cover 3 closes the upper side of the mounting frame 1, the back plate 5 closes the rear side of the mounting frame 1, and then the box door 4 is opened to install the electrical components in the mounting frame 1. Then, the cables are connected to the electrical components from the access slots on the lower side of the mounting frame 1 to distribute the electricity used by the building electrical equipment. Then, the box door 4 is closed to close the mounting frame 1. When the box door 4 is closed, the extrusion member 66 is driven to move, so that the extrusion member 66 squeezes the push rod 64, so that the push rod 64 moves backward on the guide seat 63, and the first spring 65 is squeezed and contracted, thereby causing the push rod 64 to move backward on the guide seat 63. The rod 64 pushes the upper part of the second connecting member 62 to swing backward, thereby rotating the rotating seat 60, driving the cable management plate 61 to rotate, so that the cable management plate 61 presses the cables onto the mounting frame 1, thereby playing the role of pressing and fixing the cables while closing the box door 4, improving the stability of the cable connection, and blocking the cable access groove to prevent animals such as mice from entering the box. When the box door 4 is opened, the extrusion member 66 disengages from the push rod 64, and the first spring 65 rebounds, so that the push rod 64 is reset, and the rotating seat 60 is reset by gravity, so that the cable management plate 61 no longer presses the cables, which is convenient for maintenance.

[0041] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10As shown, a ventilation mechanism 7 is also included, and the ventilation mechanism 7 includes a rotating plate 70, a rotating member 71, a pushing frame 72, an electric push rod 73 and a temperature and humidity monitoring module 74. Ten rotating plates 70 are rotatably connected between two adjacent first connecting members 0, and the rear sides of the rotating plates 70 are connected to rotating members 71. The inner sides of the left and right parts of the mounting frame 1 are slidably connected to the pushing frames 72, and the pushing frames 72 are movably connected to the adjacent rotating members 71. The inner sides of the left and right parts of the mounting frame 1 are connected to electric push rods 73, and the electric push rods 73 are located above the pushing frames 72. The telescopic ends of the electric push rods 73 are connected to the adjacent pushing frames 72. The inner sides of the left and right parts of the mounting frame 1 are connected to temperature and humidity monitoring modules 74, and the temperature and humidity monitoring modules 74 are located in front of the electric push rods 73. The temperature and humidity monitoring modules 74 are connected to the adjacent electric push rods 73 through wires.

[0042] By using the ventilation mechanism 7 of the present device, the internal ventilation can be controlled according to the situation inside the mounting frame 1. The temperature and humidity monitoring module 74 monitors the temperature and humidity inside the mounting frame 1. When the temperature and humidity inside the mounting frame 1 are high, the temperature and humidity monitoring module 74 controls the electric push rod 73 to start, so that the electric push rod 73 pushes the pushing frame 72 to move downward, so that the pushing frame 72 pushes the rotating member 71 to rotate, and then the rotating plate 70 rotates to leak out of the ventilation slot on the mounting frame 1 for ventilation, thereby playing a role in controlling the internal ventilation according to the situation inside the mounting frame 1 and reducing the entry of dust.

[0043] like Figure 1 , Figure 2 , Fig.11 , Fig.12 and Fig.13 As shown, it also includes an ejection mechanism 8, which includes a guide column 80, a mounting plate 81, a second spring 82, a third connecting member 83 and an ejection member 84. The front sides of the upper and lower parts of the back plate 5 are connected to the left and right guide columns 80, and the mounting plate 81 is slidably connected between the guide columns 80. The second spring 82 is connected between the guide columns 80 and the mounting plate 81. The front sides of the left and right parts of the mounting plate 81 are connected to the upper and lower third connecting members 83. The upper and lower parts of the push frame 72 are connected to the ejection member 84, and the ejection member 84 is squeezed and matched with the adjacent third connecting member 83.

[0044] The ejection mechanism 8 of the device can speed up the ventilation in the mounting frame 1. When installing electronic components, the electronic components are installed on the mounting plate 81. When the push frame 72 moves downward, the ejection member 84 is driven to move downward, so that the ejection member 84 squeezes the third connecting member 83, so that the third connecting member 83 moves forward, and drives the mounting plate 81 to move forward. The second spring 82 is squeezed and contracted, thereby increasing the gap between the mounting plate 81 and the back plate 5, and speeding up the ventilation in the mounting frame 1. After the push frame 72 is reset, the ejection member 84 is separated from the third connecting member 83, and rebounds through the second spring 82, so that the mounting plate 81 is reset.

[0045] like Figure 1 , Figure 2 and Fig.14 As shown, it also includes an air supply mechanism 9, which includes a fixing frame 90, a filter 91 and a fan 92. The left and right parts of the mounting frame 1 are connected to the fixing frame 90, and the filter 91 is clamped on the fixing frame 90. The upper and lower fans 92 are connected to the sides of the fixing frame 90 that are close to each other.

[0046] By using the air supply mechanism 9 of the present device, air can be supplied to the mounting frame 1. When the mounting frame 1 is ventilated, the fan 92 is started to supply air to the mounting frame 1, and the filter 91 filters the air, and the air is discharged from the lower part of the filter 91, thereby playing a role in accelerating the air circulation in the mounting frame 1.

[0047] like Figure 1 , Figure 2 and Fig.15 As shown, a sealing mechanism 10 is also included. The sealing mechanism 10 includes a rubber pad 101 . The front side of the front frame 2 is connected to the rubber pad 101 .

[0048] The sealing mechanism 10 of the device can enhance the sealing between the door 4 and the front frame 2. When the door 4 is closed to seal the mounting frame 1, the door 4 contacts the rubber pad 101, thereby enhancing the sealing between the door 4 and the front frame 2.

[0049] like Figure 2 and Fig.15 As shown, a placing mechanism 11 is also included, and the placing mechanism 11 includes a placing rack 111, and the lower rear side of the front frame 2 is connected to the placing rack 111.

[0050] By using the placement mechanism 11 of the device, the inside of the mounting rack 1 can be dried. The desiccant is placed in the placement rack 111. When the humidity inside the mounting rack 1 is high, the desiccant absorbs moisture, thereby drying the inside of the mounting rack 1 and avoiding affecting the operation of the internal electronic components.

[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
