Maintenance includes regular inspection, maintenance and repair to ensure the normal operation of each part of the elevator and prevent failures. In order to prevent unauthorized personnel from entering the elevator shaft and suffering from falling accidents, a convenient elevator maintenance modular fence is needed. Through this design, the elevator maintenance modular fence ensures the safety of the elevator shaft and prevents the risk of accidental falling by non-staff.

[0003] During the use of traditional convenient elevator maintenance combined fences, the brackets of the combined fences are usually fixed to the elevator shaft wall or the ground to ensure that their structure is stable and reliable and not easy to move or tilt. The fences are equipped with handrails, and maintenance personnel can rely on the handrails for support and balance to ensure their stability during the maintenance process.

[0004] However, it has not solved the problem that traditional fences are only connected by plastic opening buckles. When in use, the fences can be separated by applying a slight force, which poses a certain danger and leads to the problem of no warning, so that there are gaps and non-professionals may accidentally enter the maintenance area.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4The utility model provides an embodiment: a portable elevator maintenance combined fence, including a railing 1, one side of the railing 1 is rotatably connected to a connecting block 2, one side of the connecting block 2 is fixedly connected to a connecting column 3, the other side of the railing 1 is rotatably connected to a connecting block 2 11, one side of the connecting block 2 11 is fixedly connected to a connecting seat 12, a slot 13 is provided inside the connecting seat 12, a limiting column 4 is fixedly connected inside the connecting column 3, the outer wall of the limiting column 4 is slidably connected to a symmetrically arranged limiting ring 5, and the outer wall of the limiting ring 5 is provided with a limiting The outer wall of the limit ring 5 is rotatably connected to a connecting rod 9, one end of the connecting rod 9 is rotatably connected to a wedge-shaped card block 10, the outer wall of the wedge-shaped card block 10 is embedded in the card slot 13, a limit slot 8 is provided inside the connecting column 3, the outer wall of the limit column 4 is sleeved with a first spring 7, one end of the first spring 7 is fixedly connected to the inside of the connecting column 3, and the other end of the first spring 7 is fixedly connected to one end of the limit ring 5. The limit assembly includes a limit block 6, one end of the limit block 6 is fixedly connected to the outer wall of the limit ring 5, and the outer wall of the limit block 6 is slidably connected to the inside of the limit slot 8;

[0032] Specifically, when multiple railings 1 need to be combined, align the connecting column 3 on one side of a railing 1 with the connecting seat 12 on another railing 1, and then gently insert it. When the connecting column 3 is fully inserted into the connecting seat 12, the wedge-shaped block 10 will be embedded under the guidance of the card slot 13 to form a chimeric lock. In order to ensure the stability and accuracy of the wedge-shaped block 10 during the chimeric process, the connecting rod 9 tightly connects the wedge-shaped block 10 with the limiting ring 5, and the limiting ring 5 is limited in the connecting column 3 through the limiting column 4. In this way, even under the action of external force, the wedge-shaped block 10 will not be easily displaced or misplaced. In addition, in order to prevent the wedge-shaped block 10 from being misplaced due to rotation when it is retracted into the connecting column 3, the limiting block 6 is fixed on the limiting ring 5, and the limiting groove 8 is located at the corresponding position of the connecting column 3. When the limiting ring 5 moves in the connecting column 3, the limiting block 6 will slide in the limiting groove 8, thereby effectively preventing the limiting ring 5 from rotating with the limiting column 4 as the center. The first spring 7 supports the limiting ring 5 with its tension, and then supports the wedge-shaped block 10 through the connecting rod 9. This support not only ensures the stability of the wedge-shaped block 10 in the embedded slot 13, but also makes it difficult for the wedge-shaped block 10 to slide out when subjected to external force.

[0033] Reference Figure 2 and Figure 3The bottom of the railing 1 is fixedly connected with a support leg 20, the bottom of the support leg 20 is fixedly connected with a brake pad 22, a universal wheel 21 is arranged inside the brake pad 22, a limit plate 15 is arranged inside the connecting seat 12, a positioning groove 16 is opened inside the limit plate 15, a positioning block 14 is fixedly connected inside the connecting seat 12, the outer wall of the positioning block 14 is slidably connected inside the positioning groove 16, the outer wall of the limit plate 15 is slidably connected inside the connecting seat 12, a pressure block 18 is fixedly connected to the top of the limit plate 15, a top block 17 is fixedly connected to the bottom of the limit plate 15, and a second spring 19 is sleeved on the outer wall of the top block 17, one end of the second spring 19 is fixedly connected to the bottom of the limit plate 15, and the other end of the second spring 19 is fixedly connected to the inside of the connecting seat 12;

[0034] Specifically, the handrail 1 is pushed to the elevator door position to be blocked by the legs 20. When the handrail 1 reaches the designated position, in order to ensure its stability, the brake pad 22 needs to be fixed by stepping on the universal wheel 21. This operation can effectively prevent the handrail 1 from moving or shaking when subjected to external force. When the handrail 1 needs to be separated from the elevator door position, the top block 17 is driven to move by pressing the pressure block 18, thereby retracting the wedge-shaped block 10 into the connecting column 3. This process is a key step in separating the handrail 1, which ensures that the connection between the connecting column 3 and the connecting seat 12 can be released smoothly.

[0035] Working principle: When using the convenient elevator maintenance combined fence, first, when multiple railings 1 need to be combined, it is only necessary to insert the connecting column 3 on one side of a railing 1 into the connecting seat 12 on the other railing 1, and the wedge-shaped card block 10 in the connecting column 3 is embedded in the card groove 13 for embedding and locking. The wedge-shaped card block 10 is connected to the limit ring 5 through the connecting rod 9, and the limit ring 5 is limited in the connecting column 3 through the limit column 4. The limit ring 5 is limited in the limit groove 8 through the limit block 6 to prevent the wedge-shaped card block 10 from retracting into the connecting column 3 and rotating out of position with the limit column 4 as the center of the circle through the limit ring 5, so that the wedge-shaped card block 10 cannot be reset, and the tension of the first spring 7 is used to prevent the wedge-shaped card block 10 from being retracted into the connecting column 3. The limiting ring 5 is supported so that the limiting ring 5 supports the wedge-shaped block 10 through the connecting rod 9, so that the wedge-shaped block 10 is not easy to slide out when embedded in the card slot 13. Then the handrail 1 is pushed to the elevator door position required to be blocked by the supporting legs 20, and the brake pad 22 is fixed by stepping on the universal wheel 21. When the handrail 1 needs to be separated, the pressing block 18 is pressed to drive the top block 17 to retract the wedge-shaped block 10 into the connecting column 3, and then the connecting column 3 is separated from the connecting seat 12. Release the pressing block 18, and the top block 17 will be reset by pushing the limiting plate 15 under the tension of the second spring 19. The limiting plate 15 slides on the outer wall of the positioning block 14 through the positioning groove 16 for limiting.
