[0007] By adopting the above technical scheme, the sliding groove is arranged on the box body for inserting and sliding the sliding block, so that the worker can manually slide the top plate outwards from the top of the box body along the horizontal direction until the sliding block slides to abut against the outer end groove wall of the sliding groove, at this time, the plate body has been completely removed from the top area of the box body, and the plate body can be turned downwards to the side surface of the box body through the rotating connection structure between the plate body and the slat, which not only realizes the complete exposure of the outer surface of the top plate, facilitates the worker to remove the dust, sundries or accumulated water on the top plate, but also makes the top area of the box body completely open, which is convenient for the worker to intuitively check the top state and perform necessary maintenance operation, and the worker does not need to use a ladder, climbing equipment or other tools to perform high-altitude operation, thereby reducing the operation risk of the worker during cleaning and maintenance, improving the efficiency and quality of cleaning and maintenance, further improving the cleanliness and safety of maintaining the overall operation environment of the ring network box, and being beneficial to prolonging the service life of the equipment.

[0008] Optionally, the box body is provided with a receiving groove, a rotating plate is rotatably connected in the receiving groove, and the top plate is slidably connected to the rotating plate. A positioning groove is formed in the bottom wall of the receiving groove, and the bottom wall of the positioning groove is inclined. The distance from the bottom wall of the positioning groove to the receiving groove gradually decreases in the direction in which the top plate is separated from the box body. A positioning block for driving the rotating plate to rotate is slidably connected in the positioning groove. A first gear is arranged on the supporting shaft, and a first rack is arranged in the box body and engaged with the first gear. A connecting groove is formed in the positioning block for inserting and sliding the first rack. When the box door is rotated in the opening direction, the first gear drives the first rack to drive the positioning block to move away from the supporting shaft, and the positioning block drives the rotating plate to rotate away from the box body, and the top plate slides in the direction of separating from the top of the box body along the inclined direction of the rotating plate.

[0009] By adopting the above technical scheme, when the box door is rotated in the opening direction, the first gear drives the first rack to drive the positioning block to move away from the supporting shaft. Since the distance from the bottom wall of the positioning groove to the receiving groove gradually decreases in the direction in which the top plate is separated from the box body, the positioning block gradually rises during sliding. The positioning block can drive the rotating plate to rotate away from the box body to realize that the top plate is inclined with the rotating plate. The top plate can slide in the direction of separating from the top of the box body under the action of gravity, so that the worker can automatically slide out the top plate while opening the box door, avoiding the situation that the worker is difficult to pull out the top plate due to height limitation, and reducing the operation steps of the worker to pull out the top plate, thereby providing the worker with the time-saving and labor-saving operation experience, and further improving the convenience and work efficiency of operation.

[0010] Optionally, a moving groove is formed in the groove wall of the sliding groove and extends along the height direction of the box body. When the sliding block slides to the connecting position of the sliding groove and the moving groove, the plate body is separated from the surface of the box body, and the slat can drive the plate body to slide along the height direction of the box body.

[0011] By adopting the above technical scheme, when the sliding block slides to the connecting position of the sliding groove and the moving groove, the moving groove extends along the height direction of the box body, so that the board strip can drive the board body to fall along the height direction of the box body to adapt to the staff with lower height, so as to facilitate the staff to clean the top plate thoroughly, reduce the muscle strain and fatigue caused by the long-time head-up or hand-lifting operation of the staff, and the lowered top plate is more convenient for detailed inspection and thorough cleaning, thereby improving the quality and efficiency of the maintenance work.

[0012] Optionally, the board body is provided with a locking block for fixing the board body and the board strip, the board body is provided with a limiting hole for inserting the locking block, and the board strip is provided with a fixing hole for inserting the locking block; when the locking block is inserted into the fixing hole and the limiting hole, the board body and the board strip are fixed.

[0013] By adopting the above technical scheme, the locking block is inserted into the fixing hole and the limiting hole to fix the board body and the board strip, so as to prevent the top plate from rotating or shaking around the board strip unexpectedly due to accidental stress during lifting, cleaning or maintenance, prevent the sudden rotation of the top plate from causing collision, pinching or damage risk to the operator, surrounding equipment or the box body itself, thereby improving the stability and controllability of the operation process, and strengthening the structural safety of the equipment in the maintenance state, further ensuring the safety of the personnel and the equipment.

[0014] Optionally, the box body is provided with a second gear engaged with the first gear, the rotation direction of the first gear is perpendicular to the rotation direction of the second gear, the box body is provided with a second rack engaged with the second gear, the second rack is arranged in a ring shape, and the board strip is provided with a tooth block engaged with the second rack; when the board body is completely separated from the box body and the box door continues to rotate, the tooth block on the board strip is engaged with the second rack, and the second gear drives the second rack to drive the tooth block to move towards the ground.

[0015] By adopting the above technical scheme, when the top plate completely slides out of the box body and the box door continues to rotate in the opening direction, the first gear drives the second gear engaged with the first gear to rotate, and then drives the ring-shaped second rack engaged with the second gear to move. Since the board strip is provided with the tooth block engaged with the second rack, the movement of the second rack will drive the tooth block and the top plate connected thereto to stably fall along the vertical direction towards the ground. This design further realizes the automatic adjustment of the height of the top plate after the top plate slides out, so that the top plate is lowered to a position convenient for operation, and the staff can easily touch the surface of the top plate without the need to stand on tiptoe or use tools, thereby facilitating cleaning, inspection and other operations. This not only further reduces the operation difficulty and physical burden, but also improves the safety of the maintenance operation and the smoothness of the man-machine cooperation, and enhances the ease of use of the whole equipment.

[0016] Optionally, a fixing member for limiting the opening angle of the door is slidably connected to the box, and the fixing member is located on the rotation path of the door; when the door abuts against the fixing member, the second rack is engaged with the tooth block, and the slider enters the intersection of the sliding groove and the moving groove; when the door continues to pass through the fixing member, the second rack is driven by the second gear to move the tooth block towards the ground.

[0017] By adopting the above technical scheme, when the staff rotates the door, the horizontal movement and vertical landing of the top plate can be divided into two steps by the fixing member slidably connected to the box for limiting the opening angle of the door. The staff needs to manually disengage the fixing member from the rotation path of the door before continuing to rotate the door. Then, the second rack is engaged with the tooth block to drive the top plate to stably descend towards the ground, so as to realize precise triggering and control of the top plate descending action, effectively avoid the risk of accidentally triggering the top plate to directly and quickly descend and injure personnel or equipment due to excessive opening of the door, and significantly improve the safety of operation. The two-stage action provides a time window for observation and confirmation for the staff, so that they can fully check the environment around the side of the box before performing the top plate descending, and eliminate interference or personnel retention hidden dangers, further improving the safety of the staff's work.

[0018] Optionally, a groove is formed in the groove wall of the moving groove for inserting the locking block, and a first magnet is arranged on the bottom wall of the groove. A second magnet is arranged on the locking block and is attracted to the first magnet. When the slider abuts against the groove wall on the ground side of the moving groove, the locking block is aligned with the groove, and the first magnet is attracted to the second magnet. The locking block can be disengaged from the limiting hole to realize rotation of the plate body.

[0019] By adopting the above technical scheme, when the slider abuts against the groove wall on the ground side of the moving groove, the locking block is aligned with the groove, so that the first magnet on the bottom wall of the groove and the second magnet on the locking block are attracted to each other. The locking block can be automatically and stably inserted into the groove, thereby automatically releasing the rotation constraint of the plate body. After the top plate falls to the lowest position, it can be immediately flipped freely without manual intervention for additional unlocking operation, which is convenient for the staff to thoroughly clean the top plate.

[0020] Optionally, a clamping block is arranged on the fixing member, and the clamping block is located on the rotation path of the door after the door passes through the fixing member. An operating rod is arranged on the fixing member, and an operating hole is formed in the groove wall of the groove for inserting the operating rod. When the clamping block is located on the rotation path of the door, the operating rod is inserted into the groove to block the first magnet from attracting the second magnet. When the clamping block is disengaged from the rotation path of the door, the operating rod is disengaged from the groove, and the locking block can be disengaged from the limiting hole by the attraction of the first magnet and the second magnet.

[0021] By adopting the technical scheme, the clamping block can limit the continuous rotation of the box door by being located on the moving path of the box door after the fixing piece, the operating rod is inserted into the groove to block the mutual adsorption of the first magnet and the second magnet, so as to keep the effective state of the rotation limiting of the locking block to the plate body, the staff needs to slide the fixing piece to make the clamping block separate from the rotation path of the box door, so that the operating rod exits the groove, and the first magnet and the second magnet can be automatically adsorbed under the magnetic attraction, so that the locking block separates from the limiting hole, the plate body is unlocked and rotates, the linkage of the clamping block and the operating rod is used to realize the double control of the rotation locking of the plate body, so as to further improve the safety and controllability of the operation process.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing a sliding groove on the box body for the sliding block to slide, the staff can manually slide the top plate outwards from the top of the box body along the horizontal direction until the sliding block slides to the outer end wall of the sliding groove, at this time the plate body has been completely removed from the top area of the box body, through the rotation connection structure between the plate body and the slats, the plate body can be flipped downwards to the side of the box body, not only realizing the complete exposure of the outer surface of the top plate, but also facilitating the staff to clean the dust, debris or water on the top plate, and making the top area of the box body completely open, so that the staff can intuitively check the top state and perform necessary maintenance operations, without the need for tools such as ladders and climbing equipment for high-altitude work, reducing the operation risk of the staff during cleaning and maintenance, and improving the efficiency and quality of cleaning and maintenance, further improving the cleanliness and safety of the overall operating environment of the ring network box, and prolonging the service life of the equipment.

[0023] 2. When the box door rotates in the opening direction, the first gear drives the first rack to drive the positioning block to move away from the support shaft, since the distance from the bottom wall of the positioning groove to the accommodating groove gradually decreases in the direction of the top plate separating from the box body, the positioning block gradually lifts during the sliding process, and the positioning block can drive the rotating plate to rotate away from the box body to tilt the top plate, so that the top plate can slide away from the top of the box body under the action of gravity, thereby realizing that the staff can automatically slide out the top plate while opening the box door, avoiding the situation that the staff cannot easily pull out the top plate due to height restrictions, and reducing the operation steps of the staff to pull out the top plate, providing a time-saving and labor-saving operation experience for the staff, and further improving the convenience and work efficiency of the operation.

A first gear (12) is provided on the support shaft (12). 1) The housing (1) is provided with a first rack (171) that meshes with the first gear (121), and the positioning block (17) is provided with a connecting groove (172) for the first rack (171) to be inserted and slid. When the door (13) is rotated in the opening direction, the first gear (121) drives the first rack (171) to drive the positioning block (17) to move away from the support shaft (12), and the positioning block (17) drives the rotating plate (16) to rotate away from the housing (1). The top plate (2) slides away from the top of the housing (1) along the tilt direction of the rotating plate (16).

3. A ring mesh box with an easy-to-clean top as described in claim 1, characterized in that: The sliding groove (14) has a moving groove (18) on its wall, and the moving groove (18) extends along the height direction of the box (1). When the slider (223) slides to the connection between the sliding groove (14) and the moving groove (18), the plate (21) is separated from the surface of the box (1), and the strip (22) can drive the plate (21) to slide along the height direction of the box (1).

4. A ring mesh box with an easy-to-clean top as described in claim 1, characterized in that: The plate (21) is provided with a locking block (23) for fixing the plate (21) and the strip (22). The plate (21) is provided with a limiting hole (214) for the locking block (23) to be inserted, and the strip (22) is provided with a fixing hole (224) for the locking block (23) to be inserted. When the locking block (23) is inserted into the fixing hole (224) and the limiting hole (214), the plate (21) and the strip (22) are fixed.

5. A ring mesh box with an easy-to-clean top as described in claim 1, characterized in that: The housing (1) is provided with a second gear (122) that meshes with the first gear (121). The rotation direction of the first gear (121) is perpendicular to the rotation direction of the second gear (122). The housing (1) is provided with a second rack (19) that meshes with the second gear (122). The second rack (19) is set as a ring. The plate (22) is provided with a tooth block (225) that meshes with the second rack (19). When the plate (21) is completely slid away from the housing (1) and the door (13) continues to rotate, the tooth block (225) on the plate (22) meshes with the second rack (19). The second gear (122) drives the second rack (19) to drive the tooth block (225) to move towards the ground.

6. A ring mesh box with an easy-to-clean top as described in claim 5, characterized in that: The box body (1) is slidably connected to a fixing member (3) for limiting the opening angle of the box door (13). The fixing member (3) is located on the rotation path of the box door (13). When the box door (13) abuts against the fixing member (3), the second rack (19) meshes with the tooth block (225), and the slider (223) enters the junction of the sliding groove (14) and the moving groove (18). When the box door (13) continues to pass through the fixing member (3), the second gear (122) drives the second rack (19) to drive the tooth block (225) to move towards the direction closer to the ground.

7. A ring mesh box with an easy-to-clean top as described in claim 6, characterized in that: The moving groove (18) has a groove (181) on its wall for inserting the locking block (23). The bottom wall of the groove (181) is provided with a first magnet (182), and the locking block (23) is provided with a second magnet (231) that attracts the first magnet (182). When the slider (223) abuts against the wall of the moving groove (18) on the side closest to the ground, the locking block (23) aligns with the groove (181) and the first magnet (182) attracts the second magnet (231). The locking block (23) can disengage from the limiting hole (214) to allow the plate (21) to rotate.

8. A ring mesh box with an easy-to-clean top as described in claim 7, characterized in that: The fixing member (3) is provided with a locking block (31), which is located on the rotation path of the door (13) after passing through the fixing member (3). The fixing member (3) is provided with an operating rod (321), and the groove wall of the groove (181) is provided with an operating hole for the operating rod (321) to be inserted. When the locking block (31) is located on the rotation path of the door (13), the operating rod (321) is inserted into the groove (181) to block the first magnet (182) from attracting the second magnet (231). When the locking block (31) is removed from the rotation path of the door (13), the operating rod (321) is removed from the groove (181), and the locking block (23) can be removed from the limiting hole (214) by the attraction of the first magnet (182) and the second magnet (231).
