Description

Technical Field

[0001] This utility model relates to the field of low-voltage boxes, specifically a small low-voltage box. Background Technology

[0002] A low-voltage distribution box is a centralized box for low-voltage lines. It is generally used in modern home decoration for centralized management of lines such as network cables, telephone lines, computer monitors, USB cables, VGA, component video, and antenna lines for televisions.

[0003] Currently, most small low-voltage boxes are designed with a hinged door. A hinged door requires a large external space to open. In some confined installation environments, such as corridors or corners, the door can easily interfere with surrounding walls, pipes, or other equipment, making it impossible to open completely. This causes great inconvenience to the installation, debugging, and maintenance of the equipment. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a small low-voltage electrical box.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A small low-voltage electrical box includes a box body with ventilation holes on the left and right side walls and an opening on the front. Guide grooves are formed on the upper and lower parts of the left and right inner side walls, extending forward and backward, and located in the front half of the box body. The length of the guide grooves is equal to the length of the upper door. An upper door is located between the two upper guide grooves, and a lower door is located between the two lower guide grooves. The upper and lower doors have identical structures. The outer walls of the upper and lower doors slide against the inner wall of the box body. Guide wheels are rotatably mounted on the left and right sides of opposite ends of the upper and lower doors, located within guide grooves and slidingly engaging with them. Handles are fixedly connected to the middle of opposite ends of the front outer walls of the upper and lower doors. Stop bars are fixedly connected to the front sides of the left and right inner side walls of the box body, located between the upper and lower guide grooves. The edges of the upper and lower doors are arc-shaped.

[0007] The handle of the lower compartment door has locking posts on both the left and right sides. The locking posts are fixedly connected to the upper part of the front side wall of the lower compartment door. The handle of the upper compartment door has fixing posts on both the left and right sides. The fixing posts are fixedly connected to the lower part of the front side wall of the upper compartment door. The fixing posts are located above the locking posts. The outer wall of the fixing posts is rotatably connected to the buckle. The lower outer side of the buckle has a locking groove, and the locking posts engage with the locking groove.

[0008] The beneficial effects of this utility model are:

[0009] Both the upper and lower doors of this utility model can be rotated and pulled out to open. Compared with the overall hinged door, it does not take up too much extra space outside the cabinet during the opening process. Especially in environments with limited space, it can avoid interference with other equipment or obstacles when the cabinet door is opened, thus improving space utilization.

[0015] like Figure 1-4 As shown: A small low-voltage electrical box includes a box body 1. Ventilation holes are provided on the left and right side walls of the box body 1. The front of the box body 1 is open. Guide grooves 2 are provided on the upper and lower parts of the left and right inner side walls of the box body 1, extending forward and backward. The guide grooves 2 are located in the front half of the box body 1, and the length of the guide grooves 2 is equal to the length of the upper box door 3. An upper box door 3 is located between the two upper guide grooves 2, and a lower box door 4 is located between the two lower guide grooves 2. The upper box door 3 and the lower box door 4 have the same structure. The outer wall of the upper door 3 and the inner wall of the box 1 are slidably fitted. Guide wheels 5 are rotatably installed on the left and right sides of the opposite ends of the upper door 3 and the lower door 4. The guide wheels 5 are located in the guide groove 2 and are slidably fitted with the guide groove 2. Handles 6 are fixedly connected to the middle of the opposite ends of the front outer walls of the upper door 3 and the lower door 4. The front sides of the left and right inner walls of the box 1 are fixedly connected to the baffles 7. The baffles 7 are located between the upper and lower guide grooves 2. The edges of the upper door 3 and the lower door 4 are arc-shaped, and the arcs are on the opposite edges of the handles 6.

[0016] The handle 6 of the lower compartment door 4 has a locking post 8 on both the left and right sides. The locking post 8 is fixedly connected to the upper part of the front side wall of the lower compartment door 4. The handle 6 of the upper compartment door 3 has a fixing post 9 on both the left and right sides. The fixing post 9 is fixedly connected to the lower part of the front side wall of the upper compartment door 3. The fixing post 9 is located above the locking post 8. The outer wall of the fixing post 9 is rotatably connected to the buckle 10. The lower outer side of the buckle 10 has a locking groove 11. The locking post 8 is engaged with the locking groove 11.

[0017] Initially, the upper door 3 and the lower door 4 are in the closed position. At this time, the handles 6 at the middle of the opposite ends of the front outer walls of the upper door 3 and the lower door 4 are in the opposite position. The baffle 7 is located between the upper and lower guide grooves 2, which plays a certain role in limiting and blocking, preventing the door from rotating excessively. At the same time, the slots 11 of the two latches 10 respectively engage with the two latches 8, so that the upper door 3 and the lower door 4 are fixed to each other and jointly close the front opening of the box body 1.

[0018] When it is necessary to open the box door to operate or dissipate heat from the equipment inside the low-voltage box, first manually operate the latch 10 to rotate it around the fixed post 9, so that the locking post 8 can be disengaged from the locking slot 11, thus releasing the fixed connection between the upper box door 3 and the lower box door 4. Then, by pulling the handle 6 on the upper box door 3 and the lower box door 4, the upper box door 3 and the lower box door 4 can be rotated upward and downward around the guide wheel 5, thereby opening the front opening of the box 1. Then push the upper box door 3 and the lower box door 4 to slide backward along the guide groove 2.

[0019] Because the guide wheel 5 and the guide groove 2 slide together, the sliding friction can be reduced, making the door slide more smoothly, which makes it easier for operators to maintain the equipment inside the box or to dissipate heat inside the box more quickly.

[0020] After the operation is completed, slide the upper box door 3 and the lower box door 4 forward along the guide groove 2, and then rotate them back to the initial angle so that the upper box door 3 and the lower box door 4 return to the closed position. Then, operate the buckle 10 again to rotate it around the fixed post 9 and insert the locking post 8 into the locking groove 11 to achieve the fixed connection between the upper box door 3 and the lower box door 4, and re-close the front opening of the box body 1.
