Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a fence device for easy elevator maintenance, including four sets of support columns 1, protective nets 2, adjusting pipes 3, adjusting rods 4, adjusting mechanisms, and disassembly and assembly mechanisms; three sets of protective nets 2 are arranged between one side of the four sets of support columns 1, two sets of adjusting pipes 3 are connected to both ends of the protective nets 2, two sets of adjusting rods 4 are arranged at both ends of the adjusting pipes 3, two sets of adjusting mechanisms are arranged between the two ends inside the adjusting pipes 3 and one end of the two sets of adjusting rods 4, and one end of the adjusting rod 4 is connected to one end inside the adjusting pipe 3 through the adjusting mechanism. Disassembly and assembly components for installing or disassembling the adjusting rods 4 are arranged between one end of the two sets of adjusting rods 4 and one side of the support column 1.

[0025] The assembly and disassembly assembly includes connecting blocks 5 and a fixing mechanism. Two sets of connecting blocks 5 are fixedly installed on one side of the support column 1. The connecting blocks 5 have slots. The slots on one side of the connecting blocks 5 are matched with one end of the adjusting rod 4. The slots on one side of the two sets of connecting blocks 5 are inserted into one end of the two sets of adjusting rods 4. A fixing mechanism for fixing the adjusting rod 4 is provided between the connecting blocks 5 and one end of the adjusting rod 4.

[0026] Specifically, by using the connecting block 5 and the fixing mechanism together, one end of each of the two sets of adjusting rods 4 is first inserted into the inner cavity of the slot on one side of the connecting block 5, and then the fixing mechanism is used to fix one end of the adjusting rod 4 inside the connecting block 5. Conversely, one side of the adjusting rod 4 can be removed from the inside of the connecting block 5, so as to install or remove the adjusting rod 4, thereby facilitating the replacement or maintenance of the protective net 2. This solves the problem that it is impossible to install or remove the support column 1 from the protective net 2, which makes it inconvenient to maintain the elevator fence. It reduces the complexity of operation for maintenance personnel, avoids the risk of losing tools, and improves the installation efficiency and adaptability of the fence device. At the same time, the device can be quickly separated by disassembling the components, making it convenient to transport.

[0027] The fixing mechanism includes a sliding cavity 6, a bidirectional lead screw 7, a rotating ball 8, a sliding block 9, an L-shaped limiting block 10, a first fixing hole 11, and a second fixing hole 12. The sliding cavity 6 is opened inside the support column 1. The bidirectional lead screw 7 is rotatably connected inside the sliding cavity 6. One end of the bidirectional lead screw 7 passes through the sliding cavity 6 and extends to the top of the support column 1, where it is connected to the rotating ball 8. Two sets of sliding blocks 9 are fitted to the two ends inside the sliding cavity 6. The two sets of sliding blocks 9 are threadedly connected to the two ends of the surface of the bidirectional lead screw 7. An L-shaped limiting block 10 is fixedly connected to one side of the sliding block 9. The first fixing hole 11 is opened through the top of the connecting block 5. The second fixing hole 12 is opened through the end of the adjusting rod 4. The first fixing hole 11 and the second fixing hole 12 are correspondingly set to one end of the L-shaped limiting block 10, and the inside of the first fixing hole 11 and the inside of the second fixing hole 12 are inserted into one end of the L-shaped limiting block 10.

[0028] Specifically, through the coordinated use of the sliding cavity 6, the bidirectional lead screw 7, the rotating ball 8, the sliding block 9, the L-shaped limiting block 10, the first fixing hole 11, and the second fixing hole 12, the rotating ball 8 drives the bidirectional lead screw 7, synchronously controlling the opposite movement of the sliding blocks 9 on both sides, so that the two sets of L-shaped limiting blocks 10 are simultaneously inserted into the first fixing hole 11 of the connecting block 5 and the second fixing hole 12 of the adjusting rod 4. A single rotation operation can complete the locking or unlocking between the adjusting rod 4 and the support column 1.

[0029] The adjustment mechanism includes an adjustment cavity 13, a limiting rod 14, a limiting plate 15, a telescopic spring 16, and an adjustment hole 17. The adjustment cavity 13 is opened inside one end of the adjustment rod 4. The upper end of the adjustment cavity 13 is slidably connected to the limiting rod 14. The bottom of the limiting rod 14 is fixedly connected to the limiting plate 15. A telescopic spring 16 is installed between the bottom of the limiting plate 15 and the inner wall of the lower end of the adjustment cavity 13. Several sets of adjustment holes 17 are evenly opened through one end of the surface of the adjustment tube 3. The interior of the adjustment hole 17 is adapted to one end of the limiting rod 14, and one end of the limiting rod 14 is inserted into the inner cavity of the adjustment hole 17.

[0030] Specifically, through the coordinated use of the adjusting cavity 13, limiting rod 14, limiting plate 15, telescopic spring 16, and adjusting hole 17, the adjusting rod 4 forms a telescopic structure with the adjusting tube 3 via the adjusting mechanism, limiting rod 14, and adjusting hole 17. Under the action of the telescopic spring 16, the limiting rod 14 engages with the adjusting hole 17 at different positions, enabling stepless length adjustment and facilitating the enclosure of areas of different sizes. The adjusting hole 17 is marked with graduations on its outer side, and the limiting rod 14 has a red indicator on its top, which protrudes from the graduations after insertion. This allows maintenance personnel to visually confirm the adjustment length, avoiding erroneous operations and improving safety.
