Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of network terminals, in particular to a protection box for a passive optical network terminal. Background Art
[0002] In modern communication networks, passive optical networks, as important access technologies, are widely used in the field of broadband access. Passive optical network terminals often need to be installed outdoors or in relatively harsh environments, which makes them vulnerable to external environmental factors such as rain, dust, insects, etc., resulting in equipment failures or performance degradation. In order to effectively protect passive optical network terminals from external environmental factors, a protection box is usually installed outside them.
[0003] However, most traditional protection boxes for passive optical network terminals adopt a screw fixation method. During the assembly process, it is necessary to fix them one by one with screws. During maintenance and repair, it is also necessary to remove the screws one by one, making the disassembly and assembly operations of the protection box relatively cumbersome and affecting work efficiency. Content of the Utility Model
[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a protection box for a passive optical network terminal.
[0005] Technical Solution: A protection box for a passive optical network terminal includes a box body, a box cover is arranged on the top of the box body. On the upper part of the left and right sides inside the box body, first clamping blocks are fixedly connected respectively. On the left and right sides of the bottom of the box cover, second clamping blocks are arranged respectively. On the left and right sides of the top of the box cover, connecting rods are slidably connected respectively. One ends of the two connecting rods are fixedly connected to the two second clamping blocks respectively. The other ends of the two connecting rods are fixedly connected with grips respectively. An elastic member one is connected between the second clamping block and the box cover. On the front, rear, left and right sides of the bottom of the box cover, sealing strips are movably connected. The sealing strips are used to seal the gap between the box body and the box cover. An unfolding assembly capable of unfolding the sealing strips is arranged on the box cover.
[0006] Optionally, on the front and rear sides of the top of the box cover, limiting plates two are slidably connected respectively. On the left and right sides of the top of the box cover, limiting plates one are slidably connected respectively. The limiting plates one and the limiting plates two are fixedly connected to the sealing strips in their respective orientations. The limiting plates one and the limiting plates two are connected to the upper part of the box cover with elastic members two.
[0007] Optionally, the unfolding assembly includes a rotating rod. On the left and right sides of the top of the box cover, rotating rods are rotatably connected respectively. The two ends of the rotating rod are respectively connected to the limiting plate one and the connecting rod. When the connecting rod moves in one direction, the rotating rod can drive the limiting plate one to move in the opposite direction.
[0008] Optionally, the unfolding component further includes sliding rods. Both ends of the first limiting plate are fixedly connected with sliding rods. Both ends of the second limiting plate are provided with inclined sliding grooves. The end of the sliding rod away from the first limiting plate is slidably connected with the adjacent inclined sliding groove. When the first limiting plate moves away from the box cover, the sliding rod will guide the second limiting plate to move away from the box cover synchronously under the guidance of the inclined sliding groove.
[0009] Optionally, anti-slip sleeves are sleeved on both grips.
[0010] Optionally, the maximum distance between the two grips is the distance that can be fully grasped with one hand.
[0011] Beneficial effects: Through the engagement design of the first clamping block and the second clamping block, the user can realize the quick opening and closing of the box cover only by simply operating the grip, which simplifies the assembly and disassembly operations, thereby improving the work efficiency. At the same time, by setting the sealing strip and the unfolding component, the sealing strip automatically unfolds during the descent of the box cover to avoid hindering the movement of the box cover. After the box cover is closed, the sealing strip can automatically reset and closely fit the gap between the box cover and the box body, effectively preventing the intrusion of external factors such as moisture and dust, and protecting the optical network terminal from damage.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] Referring to the embodiments herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0018] A passive optical network terminal protection box, as Figures 1 - 4 shown, includes a box body 1, a box cover 2 is arranged on the top of the box body 1, first clamping blocks 3 are fixedly connected to the left and right sides of the upper part inside the box body 1, second clamping blocks 4 are arranged on the left and right sides of the bottom of the box cover 2, connecting rods 5 are slidably connected to the left and right sides of the top of the box cover 2, one ends of the two connecting rods 5 are respectively fixedly connected to the two second clamping blocks 4, the other ends of the two connecting rods 5 are each fixedly connected to a handle 6, the maximum distance between the two handles 6 is the distance that can be fully held by one hand, an elastic member 7 is connected between the second clamping block 4 and the box cover 2, sealing strips 8 are movably connected to the front side, rear side, left side and right side of the bottom of the box cover 2, and the sealing strips 8 are used to block the gap between the box body 1 and the box cover 2, and an unfolding assembly capable of unfolding the sealing strips 8 is arranged on the box cover 2.
[0019] Limit plates two 10 are slidably connected to the front side and rear side of the top of the box cover 2, limit plates one 9 are slidably connected to the left side and right side of the top of the box cover 2, the limit plates one 9 and the limit plates two 10 are fixedly connected to the sealing strips 8 in their respective orientations, and elastic members two 11 are connected between the limit plates one 9 and the limit plates two 10 and the upper part of the box cover 2.
[0020] The unfolding assembly includes a rotating rod 12, the rotating rods 12 are rotatably connected to the left and right sides of the top of the box cover 2. In this embodiment, the rotating rods 12 on the left and right sides of the top of the box cover 2 are both a pair. Both ends of the rotating rod 12 are provided with sliding grooves, a fixed rod is connected to the limit plate one 9, a U-shaped rod is connected to the connecting rod 5, and each rotating rod 12 is slidably connected to a rod end of the fixed rod on the limit plate one 9 and a rod end of the U-shaped rod on the connecting rod 5 through the sliding grooves at its two ends. When the connecting rod 5 moves in one direction, the rotating rod 12 can drive the limit plate one 9 to move in the opposite direction.
[0021] The unfolding assembly further includes a sliding rod 13, sliding rods 13 are fixedly connected to both ends of the limit plate one 9, inclined sliding grooves 14 are opened at both ends of the limit plate two 10, and the end of the sliding rod 13 far from the limit plate one 9 is slidably connected to the adjacent inclined sliding groove 14. When the limit plate one 9 moves away from the box cover 2, the sliding rod 13 will guide the limit plate two 10 to move away from the box cover 2 synchronously under the guidance of the inclined sliding groove 14.
[0022] Anti-slip sleeves 15 are sleeved on the two handles 6, and the anti-slip sleeves 15 can increase the stability and friction when the user holds the handles 6, prevent operation errors caused by hand slipping, and ensure the safety and reliability of the operation.
[0023] Working principle: When in use, the user holds the two grips 6 with one hand and applies appropriate force to make the two grips 6 approach each other. This action is transmitted to the second latch 4 through the connecting rod 5, causing the two second latches 4 to move simultaneously towards the center of the lid 2. During this process, the second latch 4 compresses the first elastic member 7. Subsequently, the user aligns the lid 2 with the box body 1 and applies a downward pressure to the lid 2. As the lid 2 gradually descends, the second latch 4 gradually enters the lower area of the first latch 3 until it is completely below its bottom. At this time, the user actively releases the two grips 6, and the second latch 4 moves back in the direction away from the center of the lid 2 under the elastic action of the first elastic member 7 until it is stably engaged with the first latch 3, thus maintaining the lid 2 in a tightly closed state with respect to the box body 1.
[0024] When the connecting rod 5 moves towards the center of the lid 2, through the transmission of the rotating rod 12, the first limiting plate 9 moves in the direction away from the center of the lid 2. During this process, the sliding rod 13 slides along the inclined chute 14, thereby guiding the second limiting plate 10 to move synchronously in the direction away from the center of the lid 2. In this way, the first limiting plate 9 and the second limiting plate 10 each drive the sealing strip 8 connected to them to move and unfold in the direction away from the center of the lid 2, ensuring that during the descent of the lid 2, the sealing strip 8 does not obstruct the movement of the lid 2. During this process, the second elastic member 11 is compressed and stores elastic potential energy; when the grip 6 is released and the second latch 4 returns to its original position, through the transmission of the connecting rod 5 and the rotating rod 12, the first limiting plate 9 moves in the direction towards the center of the lid 2. At the same time, under the guidance of the sliding rod 13 and the inclined chute 14, the second limiting plate 10 moves synchronously in the direction towards the center of the lid 2. Finally, the first limiting plate 9 and the second limiting plate 10 each drive the sealing strip 8 connected to them to move and return to their original positions in the direction towards the center of the lid 2. During this process, the second elastic member 11 gradually releases its elastic potential energy to assist the reset action of the sealing strip 8 and finally ensure that the sealing strip 8 tightly fits the gap between the lid 2 and the box body 1, thereby effectively improving the sealing performance of the entire protective box and preventing the intrusion of external factors such as moisture and dust, and protecting the internal components of the box body 1 from damage.
