Description

Technical Field

[0001] This utility model belongs to the field of fuse box technology, and particularly relates to a sealed fuse box. Background Technology

[0002] A sealed fuse box is a fuse device used to protect the electrical system of automobiles or other vehicles. It protects the fuse from environmental factors by placing the fuse in a sealed box to prevent external contaminants such as moisture and dust from entering. This box is usually designed to be completely sealed, with the fuse inside and sealed by screws or other means.

[0003] To ensure a good seal at the points where cables pass through the fuse box and connect to it, existing sealed fuse boxes typically install special sealing rings. These rings tightly wrap around the outer surface of the cables, providing waterproof and dustproof performance for the entire system. However, in practical applications, due to prolonged exposure to the external environment and the effects of temperature changes, these sealing rings may gradually age, corrode, or wear, leading to a decline in their sealing performance or even complete failure. Once the sealing rings lose their function, moisture and dust can enter the fuse box, affecting not only the fuse's operation but also causing safety hazards such as short circuits, and in severe cases, even fires. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a sealed fuse box with a compensation mechanism that can tightly fit the outer arc surface of the cable even when the sealing ring is corroded and worn, thus fully ensuring the sealing performance of the fuse box. This can effectively extend the overall service life of the fuse box and reduce the frequency of personnel replacing the sealing ring.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sealed fuse box, including a box body, a cover snapped onto the upper end of the box body, the box body and the cover being fixed together by various screws, multiple mounting brackets being provided inside the box body, each mounting bracket having multiple mounting holes inside, an automatic compensation sealing mechanism for sealing cables being provided at the lower end of the front side of the box body, the automatic compensation sealing mechanism including multiple fixed arc-shaped plates provided at the lower end of the front side of the box body, a mounting shell being provided at the lower end of the front side of the box body, a sliding plate being slidably arranged inside the mounting shell, multiple sliding columns being slidably arranged inside the sliding plate, a connecting plate being provided between the lower ends of the multiple sliding columns, and multiple movable arc-shaped plates being provided at the lower end of the connecting plate, the multiple movable arc-shaped plates respectively cooperating with the upper and lower adjacent fixed arc-shaped plates for installation. The assembly includes multiple movable and fixed arc-shaped plates, each with a sealing ring on its inner arc surface. The movable and fixed arc-shaped plates are bonded to the sealing rings. Multiple wire holes are located between the movable and fixed arc-shaped plates at the lower front side of the housing. An elastic compensation drive unit is located between the connecting plate and the sliding plate. A compensation adjustment assembly is located inside the mounting shell. The elastic compensation drive unit includes multiple springs located between the connecting plate and the sliding plate, each spring being sleeved on the outer arc surface of a corresponding sliding column. The compensation adjustment assembly includes a screw threaded into the mounting shell. The lower end of the screw is rotatably connected to the upper end of the sliding plate. A torsion unit is located at the upper end of the screw, including a screw head. The screw head is welded to the screw head, and a cross-shaped groove is located inside the screw head.

[0006] As a further improvement of this utility model, multiple mounting blocks are provided on the left and right sides of the box body, and mounting holes are provided inside the multiple mounting blocks.

[0007] As a further improvement of this utility model, an observation window is provided inside the installation opening at the upper end of the cover.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, by turning multiple screws with a screwdriver, the cover can be removed from the box. Then, the fuse can be installed onto the mounting bracket through the mounting hole. Next, by rotating the screw head in the opposite direction, the screw rod rotates, causing the moving arc plate on the sliding plate to move upward. The cable on the fuse can then be passed through the round hole at the bottom of the box. Then, by rotating the screw head in the forward direction, the screw rod rotates, causing the moving arc plate on the sliding plate to move downward. This, along with the sliding post, causes the sealing ring inside the moving arc plate on the connecting plate to move downward. Together with the sealing ring inside the fixed arc plate, a quick and secure seal can be achieved between the cable and the box.

[0010] Secondly, after prolonged use, the sealing ring will corrode and wear. The elastic rebound force of the spring, together with the sliding plate, can drive the sealing ring inside the moving arc plate on the sliding plate to move downwards and continuously make tight contact with the cable for sealing. The compensation mechanism can also tightly fit the outer arc surface of the cable even when the sealing ring is corroded and worn, which can fully guarantee the sealing performance of the fuse box, effectively extend the overall service life of the fuse box, and reduce the frequency of personnel replacing the sealing ring.

[0011] Thirdly, the observation window on the cover allows for a direct view of the real-time status of the internal fuse box without disassembling it, making it convenient for personnel to observe and understand.

[0012] Fourth, the box can be quickly fixed in a suitable position through the mounting holes inside the mounting block, making it easy for personnel to install. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 2As shown in Figure 3, the sealed fuse box includes a box body 101, a cover 102 is snapped onto the upper end of the box body 101, and the box body 101 and the cover 102 are fixed together by various screws 103. The box body 101 is provided with multiple mounting brackets 105, and each mounting bracket 105 has multiple mounting holes. The lower end of the front side of the box body 101 is provided with an automatic compensation sealing mechanism for sealing the cable. The upper end of the cover 102 has an observation window 106 in the mounting opening.

[0021] like Figure 3 , 4 As shown, the automatic compensation sealing mechanism includes multiple fixed arc-shaped plates 202 disposed at the lower end of the front side of the box body 101. A mounting shell 201 is disposed at the lower end of the front side of the box body 101. A sliding plate 210 is slidably disposed inside the mounting shell 201. Multiple sliding posts 206 are slidably disposed inside the sliding plate 210. A connecting plate 205 is disposed between the lower ends of the multiple sliding posts 206. Multiple movable arc-shaped plates 203 are disposed at the lower end of each connecting plate 205. The multiple movable arc-shaped plates 203 are respectively fitted and installed with adjacent fixed arc-shaped plates 202. Sealing rings 204 are disposed on the inner arc surfaces of the multiple movable arc-shaped plates 203 and the multiple fixed arc-shaped plates 202. Multiple sealing rings 204 are disposed on the lower end of the front side of the box body 101. Multiple wire holes are provided between the arc plate 203 and the fixed arc plate 202. An elastic compensation drive unit is provided between the connecting plate 205 and the sliding plate 210. A compensation adjustment component is provided inside the mounting shell 201. The elastic compensation drive unit includes multiple springs 207 provided between the connecting plate 205 and the sliding plate 210. The multiple springs 207 are respectively sleeved on the outer arc surface of the corresponding sliding column 206. The compensation adjustment component includes a screw 208 threadedly connected inside the mounting shell 201. The lower end of the screw 208 is rotatably connected to the upper end of the sliding plate 210. A torsion unit is provided at the upper end of the screw 208. The torsion unit includes a screw head 209 provided at the upper end of the screw 208. A cross groove is opened inside the screw head 209.

[0022] First, the operator uses a screwdriver to turn multiple screws 103 to remove the cover from the box 101. Then, the operator can install the fuse into the mounting bracket 105 through the mounting hole. Next, the operator uses a screwdriver to rotate the screw head 209 in the reverse direction, causing the screw rod 208 to rotate. This causes the moving arc plate 203 on the sliding plate 210 to move upward, allowing the cable on the fuse to pass through the hole at the bottom of the box 101. Then, by rotating the screw head 209 in the forward direction, the screw rod 208 rotates, causing the moving arc plate 203 on the sliding plate 210 to move downward. This, along with the sliding column 206, causes the sealing ring 204 inside the moving arc plate 203 on the connecting plate 205 to move downward, cooperating with the sealing ring 204 inside the fixed arc plate 202 to achieve a fixed seal between the cable and the box 101.

[0023] When the sealing ring 204 is corroded and worn after long-term use, the elastic rebound force of the spring 207, together with the sliding plate 210, can drive the sealing ring 204 inside the moving arc plate 203 on the sliding plate 210 to move downward and continuously make tight contact with the cable for sealing.

[0024] The observation window 106 on the cover 102 allows for a direct view of the real-time status of the internal fuse box without disassembling it.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, multiple mounting blocks 104 are provided on the left and right sides of the box body 101, and mounting holes are provided inside the mounting blocks 104.
